Description
Technical Field
The invention relates to a pipeline instrument and an implantation method in the field of medical instruments, in particular to a pipeline instrument and an implantation method for implanting the endoscope into small intestine through anus and colon.
Background
The digestive tract of the human body is called an upper digestive tract from the oral cavity to the duodenal papilla, a lower digestive tract from the ileocecal valve to the anus, and a middle digestive tract from the duodenal papilla to the ileocecal valve according to the dividing line of the visible organ marker under the endoscope. Prior to 2015, traditional medical techniques worldwide have failed to achieve atraumatic, prolonged repeated administration from the anus into the whole colon. In 2015, a technique for implanting a tube deep in the colon for fecal transplantation in the whole colon (also known as the lower digestive tract), or for wide-range administration in the whole colon, has been used clinically, which is what we invented and named endoscopic intestinal implantation (transendoscopic entral tubing, TET). The results of clinical studies of this technology were published in journal of academy 2016. In the process of widely popularizing and further researching the technology, we find that when the intestinal tract is not only bent, but also is particularly bent, a hose is placed at any part of the colon, so that the operation technology and corresponding special instruments are not easy to separate. If it were to be delivered smoothly and safely to the small intestine and secured to the inner wall of the small intestine for long-term indwelling and repeated administration, no instruments and techniques have been satisfied before. However, to date, no technology has been available to achieve the delivery of repeated doses from the anorectal indwelling catheter. The small intestine end is an important part of the immune diseases such as Crohn disease, and the small intestine end is an important part of local administration, so that the small intestine end is proved to be an important progress of the administration route. Today, with highly developed endoscope technology, in combination with the research of TET technology in the previous years, the technology only used for the whole colon implantation tube and drug delivery is broken through, and with brand new instrument design and operation technology, the technical difficulty of implanting a pipeline into the small intestine via the anus-colon path and retaining the pipeline for drug delivery is very important.
Disclosure of Invention
The invention aims to: a first object of the present invention is to provide a plumbing device for endoscopic trans-anal colonic implantation into the small intestine that facilitates the endoscopic safe implantation of one end of a flexible tunnel into the small intestine and the convenient and safe attachment thereof to the flexible tortuous intestinal wall of the small intestine.
A second object of the present invention is to provide an implantation method for an endoscopic trans-anal colonic to intestinal tract implantation.
The technical scheme is as follows: to achieve the above object, the present invention discloses a tubing set for endoscopic trans-anal colonic implantation into the small intestine, comprising a flexible elastic hollow tube having a proximal end and a distal end, and a plurality of single ring fixing wire rings fixed on the hollow tube at a distance of more than 3cm, wherein the hollow tube is threaded with an elastic guide wire freely movable in the axial direction from the proximal end, the guide wire does not penetrate out of the distal end of the hollow tube, and a guide wire-free guide tube section is formed at the distal end of the hollow tube; and the guide wire is also connected with a non-metal homogenizing booster for pushing the pipeline.
Wherein the length L of the guide wire-free guide tube section is 3-10 cm. The design of the guide wire-free catheter section is convenient for an auxiliary instrument to clamp the distal end of the hollow pipeline or a single-ring fixed wire ring at the distal end under an endoscope to enter the tail section of the small intestine after passing through the ileocecal valve from the ileocecal part, so that the probability of successful operation is increased, and the operation time is reduced.
Preferably, a boss which is convenient for pushing the pipeline is arranged at the end part of the nonmetal homogenizing booster connected with the guide wire, and the diameter of the boss is larger than or equal to that of the hollow pipeline.
Furthermore, the nonmetal homogenizing booster and the guide wire are connected by adopting a detachable clamping groove.
Further, the diameter of the hollow pipeline is more than or equal to 2.5mm.
Preferably, the doubling-over length of the wire ring of the single-ring fixed wire ring is 1-2.5 cm, and the distance L1 between adjacent single-ring fixed wire rings is more than 3cm. The single-ring fixed wire ring meets the clamping operation of the titanium clamp for fixing with the arm length of 1cm under an endoscope, avoids the situation that the fixed wire falls off in advance due to improper stress caused by overlong wire rings, and also avoids the situation that the titanium clamp cannot clamp due to overlong wire rings; while the single loop design also avoids knot tying that may cause clotting and clumping of the intestinal lumen contents. The distance between the single-ring fixed wire rings in the invention meets the requirement that the distance between the annular folds of the intestinal canal reduces the mutual traction of the two single-ring fixed wire rings in the peristaltic and extension processes, and avoids the problem that the single-ring fixed rings fall off from the intestinal wall prematurely due to the mutual traction.
And the hollow pipeline is provided with a plurality of pore canals communicated with the inside of the pipeline, and the distance L2 between the end part of the guide wire close to the distal end of the hollow pipeline and the adjacent pore canals is more than or equal to 2cm. The guide wire design of the invention completely avoids iatrogenic injury caused by the guide wire not penetrating out of the adjacent duct in the operation process.
The invention relates to an implantation method based on a pipeline instrument for implanting into small intestine through anus under an endoscope, which comprises the following steps:
(1) Firstly, the endoscope is required to be sent to a target position of the small intestine through anus and colon;
(2) Then the pipeline is required to be sent to the target position of the small intestine from the inner forceps channel hole of the endoscope;
(3) The pipeline is left in situ and pushed out of the endoscope, so that the separation of the pipeline and the endoscope is completed;
(4) When the endoscope is again accessed and the hollow pipeline with the built-in guide wire is found not to be at the target position of the small intestine, a disposable titanium clamp is used for clamping a single ring fixing ring at the far end of the hollow pipeline, then the endoscope is utilized to enter the environment, the endoscope passes through a ileocecal valve along with the endoscope, enters the small intestine to reach the target position of the small intestine, and a clamping device is conveyed from a forceps pipeline hole of the endoscope to sequentially fix the single ring fixing ring of the hollow pipeline to the intestinal wall;
(5) After the fixation is finished, the endoscope is slowly pushed out of the anus, and then the guide wire is pulled out, and the guide wire can be extruded and inserted into a connecting cap at the proximal end of the hollow pipeline, so that the infusion apparatus can be conveniently docked.
The beneficial effects are that: compared with the prior art, the invention has the following remarkable advantages:
(1) The combined structure design of the guide wire, the hollow pipeline and the nonmetal homogenizing booster is used for facilitating safe implantation of the soft pipeline front end into the small intestine under an endoscope, and the soft pipeline front end is conveniently and safely fixed on the soft and tortuous intestinal wall of the small intestine, so that the design of the device for only using the pipeline for colon implantation before breakthrough is needed;
(2) The single-ring fixed wire ring meets the clamping operation of the titanium clamp for fixing with the arm length of 1cm under an endoscope, avoids the situation that the fixed wire falls off in advance due to improper stress caused by overlong wire rings, and also avoids the situation that the titanium clamp cannot clamp due to overlong wire rings; simultaneously, the single-ring design also avoids that the knot of the thread can cause the coagulation and agglomeration of the intestinal cavity content; the distance between the single-ring fixed wire rings in the invention meets the requirement that the distance between the annular folds of the intestinal canal reduces the mutual traction of the two single-ring fixed wire rings in the peristaltic and extension processes, and avoids the problem that the single-ring fixed rings fall off from the intestinal wall prematurely due to the mutual traction;
(3) The design of the guide wire-free catheter section is convenient for an auxiliary instrument to clamp the distal end of the hollow pipeline or a single-ring fixed wire ring at the distal end under an endoscope to enter the tail section of the small intestine after passing through a ileocecal valve from a ileocecal part, so that the probability of successful operation is increased, and the operation time is reduced;

Detailed Description
The technical scheme of the invention is further described below with reference to the accompanying drawings.
As shown in fig. 1, the invention relates to a pipe device for implanting into small intestine via anus under endoscope, which comprises a hollow pipe 3, a single ring fixing wire ring 4, a guide wire 5 and a nonmetal homogenizing booster 6. The hollow tube 3 of the present invention is a flexible elastic member having a proximal end 1 and a distal end 2, wherein the hollow tube at the distal end is also referred to as the mouth side end, whereas the proximal end in the direction of the anal orifice is also referred to as the anal side end. The diameter of the hollow pipeline 3 is more than or equal to 2.5mm, the hollow pipeline 3 is provided with a plurality of pore canals 8 communicated with the pipe, and the distance L2 between the end part of the guide wire 5 near the distal end of the hollow pipeline and the adjacent pore canals 8 is more than or equal to 2cm. The diameter of the guide wire is far smaller than the inner diameter of the hollow pipeline, the space position of the guide wire in the pipeline can be uncontrollably changed due to shrinkage caused by bending radian, bending quantity and resistance, namely, if the hollow pipeline is straightened in the actual operation process, the guide wire in the hollow pipeline is also kept in a straight state, the distance from the end of the guide wire to the far end of the hollow pipeline can be obtained, but if the guide wire is bent to different degrees, the distance becomes unstable. Meanwhile, after the hollow pipeline made of different materials is processed and molded, the hollow pipeline can be shortened or lengthened due to the influences of factors such as the placement time, the temperature and the like, and when the hollow pipeline is used, a guide wire can be excessively long in the hollow pipeline and even longer than the hollow pipeline, so that the possibility of stabbing, perforating and the like of intestinal walls can be caused; furthermore, if just passed out of the tunnel, it has a very high probability of causing iatrogenic damage. The guide wire design of the invention can completely avoid the iatrogenic injury caused by the guide wire not penetrating out of the adjacent duct in the operation process.
According to the invention, a plurality of single-ring fixed wire rings 4 are fixed on a hollow pipeline 3 at intervals, and the longitudinal distance between every two adjacent single-ring fixed wire rings 4 is larger than 3cm. The doubling-over length of the wire loops of the single-ring fixed wire loops 4 is 1-2.5 cm, and the distance L1 between the adjacent single-ring fixed wire loops 4 is more than 3cm. The single-ring fixed wire ring meets the clamping operation of the titanium clamp for fixing with the arm length of 1cm under an endoscope, avoids the situation that the fixed wire falls off in advance due to improper stress caused by overlong wire rings, and also avoids the situation that the titanium clamp cannot clamp due to overlong wire rings; simultaneously, the single-ring design also avoids that the knot of the thread can cause the coagulation and agglomeration of the intestinal cavity content; the distance between the single-ring fixed wire rings in the invention meets the requirement that the distance between the annular folds of the intestinal canal reduces the mutual traction of the two single-ring fixed wire rings in the peristaltic and extension processes, and avoids the problem that the single-ring fixed rings fall off from the intestinal wall prematurely due to the mutual traction.
The guide wire 5 of the present invention is a flexible elastic homogeneous guide wire, and the guide wire 5 can freely move along the axial direction of the hollow pipe 3. The guidewire 5 penetrates the hollow tube 3 from the proximal end 1 of the hollow tube 3 without penetrating the distal end of the hollow tube 3 and forms a guidewire-free catheter section at the proximal end 1 of the hollow tube 3. The length L of the guide wire-free guide tube section is 3-10 cm. In practical operation, when the endoscope reaches the target position, the pipeline is often not in situ, if the pipeline is retracted to the colon due to the traction of the endoscope, a foreign body forceps or a disposable titanium clamp or other tools must be used for clamping the distal end of the hollow pipeline or a fixed wire ring at the distal end of the hollow pipeline under the direct vision of the endoscope, and the opportunity of the endoscope to move towards the small intestine is utilized for holding the hollow pipeline to enter the target position of the small intestine. The largest technical gateway from the large intestine to the small intestine is through a ileocecal orifice, the diameter of which is smaller than the intestinal lumen and the angle of which is large, through which the endoscope carries a hollow tube and into the tortuous intestinal lumen of the small intestine, which is prone to failure or takes a long time. For patients under anesthesia, prolonged surgery is faced with increased risk of anesthesia, increased medical costs of medication and monitoring. Therefore, the design of the guide wire-free catheter section is convenient for an auxiliary instrument to clamp the distal end of the hollow pipeline or a single-ring fixed wire ring at the distal end under an endoscope to enter the tail section of the small intestine after passing through the ileocecal valve from the ileocecal part, so that the success rate of operation is increased, and the time spent in the operation is reduced.
The guide wire 5 is also connected with a non-metal homogenizing booster 6 for pushing the pipeline, the non-metal homogenizing booster 6 is connected with the guide wire 5 by adopting a detachable clamping groove, or the non-metal homogenizing booster 6 is coated outside the guide wire 5 and integrally connected. The end part of the nonmetal homogenizing booster 6 connected with the guide wire 5 is provided with a boss 7 which is convenient for pushing the pipeline, and the diameter of the boss 7 is larger than or equal to that of the hollow pipeline 3. The guide wire 5 of the present invention is generally made of a metal material and has a smooth surface. The diameter of the nonmetallic homogenizing booster 6 is required to be smaller than the forceps channel hole of the endoscope, usually smaller than 2.7mm or smaller than 3.2mm, because the nonmetallic homogenizing booster is only required to push the hollow pipe and the guide wire thereof smoothly through the forceps channel hole of the endoscope and leave the endoscope. The surface of the non-metallic homogenizing booster 6 is smooth, preferably a plastic or polymer material is used, and no metal is present. The design of the homogeneous metal guide wire 5 and the non-metal homogeneous booster 6 of the present invention greatly reduces the medical costs.
The fixation of the present invention is typically accomplished under a selected endoscope using a disposable endoscope clip (e.g., titanium clip) within the intestinal lumen. For special treatment requirements, such as more than 2 weeks of indwelling pipelines, the indwelling pipelines can be implanted through an anus-colon way, and then a laparoscope suturing technology is utilized to fix the wire ring through the wall under the assistance of an intestinal endoscope, so that a stable fixed soft catheter is realized, and the method is very important for the long-time indwelling of the pipelines in the small intestine. The present invention is useful for transanally implanting and securing a tube to the small intestine, but is not limited to using the target site for the small intestine end segment, and may be used for the fixation of ileocecal, ascending, transverse and descending colon.
The invention relates to an implantation method based on a pipeline instrument for implanting into small intestine through anus under an endoscope, which comprises the following steps:
(1) Firstly, the endoscope is required to be sent to a target position of the small intestine through anus and colon;
(2) Then the pipeline is required to be sent to the target position of the small intestine from the inner forceps channel hole of the endoscope;

(4) When the endoscope is again accessed and the hollow pipeline with the built-in guide wire is found not to be at the target position of the small intestine, a disposable titanium clamp is used for clamping a single ring fixing ring at the far end of the hollow pipeline, then the endoscope is utilized to enter the environment, the endoscope passes through a ileocecal valve along with the endoscope, enters the small intestine to reach the target position of the small intestine, and a clamping device is conveyed from a forceps pipeline hole of the endoscope to sequentially fix the single ring fixing ring of the hollow pipeline to the intestinal wall;
(5) After the fixation is finished, the endoscope is slowly pushed out of the anus, and then the guide wire is pulled out, and the guide wire can be extruded and inserted into a connecting cap at the proximal end of the hollow pipeline, so that the infusion apparatus can be conveniently docked.
