Description

Visual puncture microwave ablation system

technical field

The invention relates to medical equipment, in particular to a visible puncture microwave ablation system.

Background technique

At present, microwave thermal ablation therapy is widely used in clinical tumor treatment, especially for liver cancer, lung cancer, kidney cancer, etc. At present, the basic process of using a microwave ablation needle in clinical practice is as follows: the microwave ablation needle is inserted into the human body under the guidance of ultrasound or X-ray, and then the treatment is performed by electric heating. In the above process, when puncturing with a puncture needle, it is usually performed in an indirect image manner under the guidance of auxiliary means such as an ultrasound probe and X-ray. However, due to the observation characteristics of indirect images, it is difficult for the operator to accurately puncture the target position at one time. As a result, multiple punctures may be required, resulting in increased trauma, delayed recovery, and possibly infection. In addition, traditional microwave ablation needles cannot directly view the puncture path because they do not have a visual function, which often causes tissue or blood vessel damage, bringing pain to patients, and at the same time, it is impossible to realize real-time monitoring of the treatment process and evaluation of the treatment situation.

Compared with the conventional microwave ablation system, the "visual puncture microwave ablation system" described in this paper can perform the puncturing and ablation functions of the functional body through the imaging illumination device located in the functional body. Blood vessels, tendons, etc.) are imaged, and the resulting image or video signal is transmitted back to an external display system in real time to assist in puncture and microwave ablation.

The "functional body" described herein is the part of the visible puncture microwave ablation system that performs puncture and microwave ablation on tissue. The functional body and the imaging illuminating device may or may not be an integral piece, and they together constitute an executive body. The actuator thus has the functions of performing puncture, microwave ablation and imaging illumination on the tissue.

The "injection cavity" described herein is a cavity located inside the functional body, through which not only medicinal liquids or other liquids required by body tissues in diagnosis and treatment, such as physiological saline, etc., can be injected from the outside, but also Other instruments required for surgery, such as laser fiber, guide wire, biopsy forceps, mesh basket, etc., are placed into the injection cavity and reach the target tissue site. Therefore, when the needle tip of the functional body reaches the target tissue site, a liquid (such as physiological saline) can be injected to flush the target tissue site for clear imaging, or to administer drugs or perform biopsy sampling treatment to the target tissue site. The proximal needle end of the imaging illuminator is juxtaposed (separate) with the infusion chamber or the proximal needle end of the imaging illuminator is contained in the infusion chamber, preferably the proximal needle end of the imaging illuminator The end is contained in the injection chamber.

The inside of the functional body also includes a microwave ablation and cooling cavity, and the microwave ablation and cooling cavity is closed by internal circulation.

The shape and size of the microwave ablation cooling cavity are not particularly limited, as long as the cooling of the functional body can be achieved.

The imaging illumination device includes a lens and an illumination device that partially or completely surrounds the lens, and the lens may be an optical lens or an electronic lens (as described in FIGS. 2 and 4 ).

FIG. 18 is a structural diagram of the evolution of the conventional microwave ablation system to the visible puncture microwave ablation system of the present invention. The cross-section of the functional body of the traditional microwave ablation needle is shown in 17-1 (shown by the shaded part of A).

The injection cavity and the microwave ablation cooling cavity are disconnected. The functional body of the present application can also be other evolved special-shaped structures, such as elliptical, gourd-shaped and other structures (as shown in Figure 18, some of the special-shaped structure embodiments, Figure 18, all shaded parts in a, b, c, d, shaded A All represent the functional body, the white parts of B all represent the injection cavity, and the black parts of C all represent the imaging lighting device). The evolved special-shaped structure is only for the description of the embodiment and does not limit the shape and combination of the functional body, the imaging lighting device and the injection cavity of the visible puncture microwave ablation system.

The first embodiment of the present invention and a visible puncture microwave ablation system 100 are shown in FIG. 1 , FIG. 2 , FIG. 3 , FIG. 4 , FIG. 5 , FIG. 6 , and FIG. 7 , including: a functional body 1 and imaging lighting device 12 . The functional body 1 has a puncture needle 11 , the puncture needle 11 has a needle head 112 at its distal end, and a needle tube 113 connected to the needle head 112 , and the needle head 112 is insulated from the needle tube 113 . A microwave conducting member 141 is connected to the needle 112 , and the needle 112 is at least partially exposed to form an ablation conducting portion 1130 . The imaging illumination device 12 is disposed in the needle tube 113 and is operable to illuminate and photograph through the distal end of the puncture needle 11 . The needle tube 113 is further provided with an injection port 131 , and the puncture needle 11 is further provided with an injection channel 13 communicating with the injection port 131 , and the injection channel 13 extends toward the needle 112 and penetrates the puncture needle 11 .

Specifically, as shown in FIG. 1 to FIG. 7 , when the visible puncture microwave ablation system is used, the puncture needle 11 is inserted into the human body, and water flow is injected from the injection port 131 at the same time, and the injection channel 13 penetrates the puncture needle 11, The water flow flows out from the needle 112 of the puncture needle 11 and expands to the periphery, so that the periphery of the needle 112 of the puncture needle 11 forms a cavity, and the imaging lighting device 12 can clearly photograph the specific position of the needle 112 of the puncture needle 11, thereby photographing to surrounding organizations. In addition, the water flow can also flush the blood around the needle 112 of the puncture needle 11 , which further enables the imaging lighting device 12 to take pictures with a clear field of view. The injection port 131 can also be injected with medicinal liquid or other liquid required by the body tissue in the treatment, and other surgical instruments such as laser fiber, guide wire, biopsy forceps and other therapeutic biopsy instruments can also be placed.

As can be seen from the above, since the imaging illuminating device 12 is provided in the needle tube 113, and the imaging illuminating device 12 can illuminate and photograph through the distal end of the puncture needle 11, when the puncture needle 11 is punctured, the injection port 131 injects the material into the Injecting liquid into the channel 13 can expand the cavity wall of the tissue and clean the interference around the needle 112 , so that the imaging illumination device 12 can clearly photograph the surrounding of the needle 112 , so that the puncture needle 11 can be accurately positioned to the lesion. After the microwave conduction member 141 conducts electricity, the ablation conduction part 1130 on the needle acts on the tissue with high-frequency electromagnetic waves such as microwaves, so that the affected tissue absorbs a large amount of microwaves, and the polar molecules in the tissue move at a high speed under the action of the microwave field. Movement, friction generates heat, and the temperature rises rapidly in the lesion tissue. When the temperature rises to about 60 degrees, the cell protein denatures and solidifies, resulting in irreversible necrosis. During the treatment process, the imaging lighting device 12 directly monitors the removal of the lesion in real time, and accomplishes the purpose of the treatment in the shortest time and with the least trauma, thereby treating the patient more safely and efficiently, and reducing the pain of the patient.

Preferably, as shown in FIG. 5 , the opening 140 of the accommodating cavity is opened on the needle 112 , so that the imaging illuminating device 12 can be photographed in a more precise orientation. And in other embodiments, the opening 140 of the accommodating cavity can also be opened on the needle tube 113 .

Further, as shown in FIG. 4 , FIG. 5 and FIG. 7 , the accommodating cavity extends along the length direction of the puncture needle 11 , and the space between the imaging illumination device 12 and the cavity wall of the accommodating cavity serves as the injection channel 13 . The gap between the imaging illuminating device 12 and the cavity wall of the accommodating cavity can be formed by separating the imaging illuminating device 12 from the cavity wall of the accommodating cavity. The injection channel 13 naturally formed between the imaging illuminating device and the cavity wall of the accommodating cavity is located in the accommodating cavity, so that it is not necessary to open up a new space to construct the injection channel 13, so that the inner space of the puncture needle 11 can be fully utilized, and the diameter of the puncture needle 11 It can be smaller, and the visible puncture microwave ablation system can be more precise. It is understandable that, in other embodiments, the injection channel 13 may also be provided outside the accommodating cavity, and the injection port 131 of the injection channel 13 may or may not communicate with the accommodating cavity.

Further, as shown in FIGS. 4 , 5 and 7 , the side of the functional body 1 away from the needle 112 is provided with a circulating medium injection port 151 and a circulating medium recovery port 161 , and the puncture needle 11 is provided with a circulating medium along the length of the puncture needle 11 .

Further, as shown in FIG. 4 , FIG. 5 and FIG. 7 , the inlet and outlet circulating medium circuit 65 has a liquid inlet channel 15 that communicates with the circulating medium injection port 151 and extends along the length direction of the puncture needle 11 , and is communicated with the circulating medium recovery port 161 and The liquid outlet channel 16 extends along the length direction of the puncture needle 11 , and the liquid inlet channel 15 communicates with the liquid outlet channel 16 . The liquid inlet channel 15 and the liquid outlet channel 16 and the opening of the needle 112 are not communicated with each other, and the cooling water is discharged through the puncture needle 11 through the liquid inlet channel 15 and the liquid outlet channel 16 . Optionally, as shown in FIG. 5 , the liquid outlet channel 16 is arranged around the outer periphery of the accommodating cavity. In other embodiments, the liquid outlet channel may also not be arranged around the accommodating cavity.

Further, the visible puncture microwave ablation system further includes: a temperature detection device arranged on the functional body.

Further, as shown in FIG. 4 , FIG. 5 and FIG. 7 , the needle tube 113 has an outer tube 1131 , a first inner tube 1132 sheathed in the outer tube 1131 , and the first inner tube 1132 has a accommodating cavity, and the first inner tube The opening of 1132 toward the needle 112 is the opening 140 of the receiving cavity. One end of the first inner tube 1132 and the outer tube 1131 facing the needle 112 is a closed end, and the area inside the first inner tube 1132 is not communicated with the area between the first inner tube 1132 and the outer tube 1131 .

A flow tube 150 is inserted between the first inner tube 1132 and the outer tube 1131, the flow tube 150 is spaced apart from the first inner tube 1132 and the outer tube 1131, and the flow tube 150 is open to one end of the needle and away from the closed end. The liquid inlet channel 15 is located in the flow pipe 150 , and the liquid outlet channel 16 is located between the first inner pipe 1132 and the outer pipe 1131 . The circulating water flows from the circulation pipe 150 into between the circulation pipe 150 and the first inner pipe 1132 and the outer pipe 1131, and then flows out. The temperature detection device is connected to the flow pipe 150 .
