Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of medical apparatus and instruments, and specifically relates to an adjustable occlusion catheter. BACKGROUND

[0002] The occlusion catheter is delivered to a target site, and then a medium is injected into the balloon to inflate the balloon, so as to realize occlusion of a specific channel or blood vessel. This occlusion can prevent the flow of blood, body fluid, etc., and create conditions for subsequent diagnosis or treatment (such as one-lung ventilation surgery) operations.

[0003] In the prior art, in order to facilitate observation of the position of the balloon, a camera is arranged on the occlusion catheter. Although the related art can improve the observation effect to a certain extent, it cannot simultaneously solve the problems of catheter exploration and balloon positioning during surgery.

[0023] To make the structure characteristics and effects of the present application clearer, the present application will be described in detail below in combination with the drawings and specific embodiments.

[0024] As shown in the drawings, Figures 1-2 In one embodiment, an adjustable occlusion catheter includes a catheter body 1, a bendable catheter front end 2 is arranged at the distal end of the catheter body 1, the bendable catheter front end 2 can make the catheter more easily enter the trachea at various angles, and has higher applicability. A first camera 3 is arranged at the head end position of the bendable catheter front end 2, the first camera 3 can observe the situation in front when the catheter front end 2 enters the trachea, so as to make the catheter enter the target position, i.e. the bronchus.

[0025] A balloon 4 is arranged outside the circumference of the catheter front end 2, and after reaching the target position, the balloon 4 can be inflated by injecting a medium (such as liquid or gas) into the balloon 4 through the liquid filling hole in the catheter (as prior art, not described here) to make the balloon 4 expand and achieve occlusion of the target position.

[0026] A camera two 5 is arranged at the proximal end of the balloon 4, i.e. the connection position of the catheter main body 1 and the catheter front end 2. Specifically, the camera two 5 is arranged at the connection between the catheter front end 2 and the catheter main body 1, and the camera two 5 is perpendicular to the connection. The camera two 5 can observe the position of the balloon 4 when the balloon 4 is positioned, so as to more efficiently position the balloon 4 to the target position.

[0027] Through the above technical solution, by arranging the camera one 3 and the camera two 5, the problems of catheter exploration and balloon 4 positioning during surgery can be solved at the same time, greatly improving the operation efficiency and safety during surgery.

[0028] Optionally, the data transmission wires of the camera one 3 and the camera two 5 pass through the catheter front end 2 and the catheter main body 1 and are connected to an external controller and a display. The video pictures taken by the camera one 3 and the camera two 5 can be observed through the display.

[0029] Optionally, a sputum suction tube is arranged inside the catheter main body 1, and a sputum suction port 6 of the sputum suction tube is arranged at the distal end of the catheter front end 2. Referring to Figure 2 , the sputum suction port 6 and the camera one 3 are at the distal end of the catheter front end 2. Through the sputum suction port 6, sputum in the bronchus can be sucked out and discharged outward through the channel in the catheter main body 1.

[0030] Optionally, a handle 7 is arranged at the end of the catheter main body 1 away from the catheter front end 2. One end of the handle 7 is provided with an angle adjuster. The angle adjuster includes at least two guide wires. The guide wires are connected through the inside of the catheter main body 1 and the catheter front end 2. The connection between the catheter front end 2 and the catheter main body 1 is a flexible tube. Both the catheter front end 2 and the catheter main body 1 have a certain flexibility. Therefore, by controlling the two guide wires, 180-degree angle adjustment of the catheter front end 2 can be realized. By controlling the two guide wires, bending at different angles can also be realized, so as to enter different angle bronchus.

[0031] Optionally, the outside of the catheter main body 1, the catheter front end 2 and the balloon 4 is coated with a hydrophilic lubricating coating, such as polyacrylamide (PAM), polyvinylpyrrolidone (PVP), polyethylene oxide (PEO), polyvinyl alcohol (PVA) and the like. By coating the hydrophilic lubricating coating, the friction with the bronchus can be reduced, and the safety can be improved.

[0032] The above description of disclosed embodiments enables one of ordinary skill in the art to make or use the application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein can be applied to other embodiments without departing from the spirit or scope of the application. Thus, the present application is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
