Description

A visual chest tube

technical field

The invention relates to the field of chest catheters, in particular to a visualized chest catheter.

Background technique

Closed thoracic drainage is the most basic surgical operation in thoracic surgery, and it is also the most basic way to observe and treat thoracic trauma. Among them, thoracic drainage tubes, referred to as chest drainage tubes and chest tubes, are currently mainly used in clinical practice. There are two types of needle chest tubes, which are the key part of the entire chest cavity closed drainage system.

In practice, the existing closed thoracic drainage is blindly penetrating the catheter, which has the safety risk of damaging important organs or adhesions in the chest, and it is difficult to achieve precise catheter placement in the chest, requiring certain surgical experience. Thoracic surgery specialists have completed it, which limits its use in the first-line clinical practice. In addition, the condition of the thoracic cavity after catheter placement needs to be indirectly judged through drainage, characteristics and imaging examinations, and there is a lack of real-time, intuitive observation and evaluation methods, leading to false positives. Diagnosing the disease increases patient risk, suffering, and unnecessary medical expenses.

SUMMARY OF THE INVENTION

Based on this, the purpose of the present invention is to provide a visual chest catheter to solve the technical problem that it is difficult to accurately place the catheter in the thoracic cavity and the situation in the thoracic cavity after the catheter is easily misjudged.

In order to achieve the above objects, the present invention provides the following technical solutions: a visual chest guide tube, comprising a main tube, a monitoring component penetrates through one side of the main tube, and a guide core component penetrates through the other side of the main tube.

Further, both sides of the inner wall of the main pipe are provided with drainage holes, the plurality of drainage holes are divided into two groups, each group of drainage holes is provided with three, and the drainage holes of the two groups are staggered from each other.

By adopting the above technical solution, the drainage holes can play a role in drainage, and the drainage holes arranged at mutual offsets can make the main pipe more stable.

Further, the monitoring component includes an auxiliary pipe, a camera is installed at the head end of the auxiliary pipe, a circuit is provided on one side of the inner side of the auxiliary pipe, and an external port is penetrated through the tail end of the circuit, and the auxiliary pipe is The diameter of the pipe above the outer surface is larger than the diameter of the pipe below the outer surface.

By adopting the above technical solution, the camera can monitor the front end of the auxiliary tube, and the line connected to the camera can be connected to the external device through the external port, providing power and outputting images, which makes the chest tube more convenient to use.

Further, the guide core assembly includes a guide core, and a slope surface is disposed in the middle of the outer surface of the guide core, and the slope surface is in a zigzag shape.

By adopting the above technical solution, the serrated slope makes it possible to keep the rotation angles of both ends of the whole head and tail as consistent as possible when the guide core is rotated when the tube is placed.

Further, the guide core is adapted to the main pipe, the core of the guide core is an aluminum rod, the outer surface of the guide core is provided with a PVC coating, and the length of the main pipe is 35-40 cm.

By adopting the above technical solution, the user can bend the guide core when needed, so as to fit the actual arc in the chest cavity and accurately place the tube, which can improve the operational safety of the chest catheter.

Compared with the prior art, the beneficial effects of the present invention are:

1. The present invention provides power supply and output image through the external port, and the catheter can be placed according to the image in the chest cavity. Even beginners can observe the situation in the chest cavity, effectively avoid important organs or adhesions in the chest cavity, and avoid blind puncture injury. , improve the safety of operation, and avoid the situation that it is difficult to achieve precise catheter placement in the thoracic cavity;

2. In the present invention, the flexible guide core can be bent according to the actual situation when the catheter is placed, cooperate with the image provided by the front camera, fit the curvature of the chest wall, accurately place the catheter in a suitable drainage position, and improve the accuracy of catheter placement. When the actual tube placement occurs, the side hole of the drainage tube is sometimes blocked by the expanded lung tissue or blood clot in the chest cavity, resulting in poor drainage and affecting the observation effect of closed drainage. The real-time image is convenient for clinicians to judge the condition and make reasonable decisions, avoiding the situation that the situation in the thoracic cavity after the catheter is easily misjudged.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary, only used to explain the present invention, and should not be construed as a limitation of the present invention.

The embodiments of the present invention will be described below based on the overall structure of the present invention.

A visual chest drainage tube, as shown in Figures 1-3, includes a main tube 1, a drainage hole 101, an auxiliary tube 2, a camera 201, a circuit 202, an external port 203, a guide core 3 and a slope 301. A monitoring component runs through one side, and a guide core component runs through the other side inside the main pipe 1 .

1-2, both sides of the inner wall of the main pipe 1 are provided with drainage holes 101, the plurality of drainage holes 101 are divided into two groups, each group of drainage holes 101 is provided with three, and the two groups of drainage holes 101 are staggered from each other, and the drainage holes 101 It can play the role of drainage, and the drainage holes 101 arranged in mutually offset positions can make the main pipe 1 more stable.
