Problems solved by technology

[0003] During the operation, the abdominal aorta needs to be cut first during the insertion of the urinary catheter. During the operation, the blood pressure of the abdominal aorta is often too high, and some donors have aortic sclerosis, which leads to blood splashing after the incision, and the blood is very easy to spray. Therefore, the close cooperation of two surgeons is required during the catheterization process, and the operation is cumbersome. There is a possibility of repeated catheterization or even catheterization failure. Massive bleeding will affect the next operation and seriously affect the Perfusion efficiency of donor organ perfusate and organ quality

Embodiment 1

[0030] Such as figure 1 and figure 2 As shown, one end of the integrated puncture and perfusion catheter in this embodiment is provided with a puncture part 1, and the other end is provided with a perfusion part 2. The perfusion part 2 is fixedly connected to the puncture part 1 and is not connected inside. Complete one-piece piercing and irrigation catheter.

[0031] Such as image 3 and Figure 4 As shown, in this embodiment, the puncture part 1 includes a puncture member 11, an accommodating channel 12, and a retraction assembly 13 that can control the retraction of the puncture member 11 into the accommodating channel 12, and the puncture member 11 is arranged in the accommodating channel 12 And the accommodating channel 12 can be stretched and retracted, and the retreating component 13 is connected with the puncture member 11 . The piercing member 11 plays the role of puncturing the blood vessel, and can be stretched into and out of the accommodation channel 12, and ...

Embodiment 2

[0042] This embodiment is basically the same as Embodiment 1, the main difference lies in the structure of the puncture part 1: as Figure 6 and Figure 7 As shown, in this embodiment, the puncture part 1 is a cylindrical structure, and the cylindrical cavity at the front end is an accommodating channel 12, which can accommodate an I-shaped puncture member 11, and one end is a sharp acupuncture solid cylinder with an inclined plane as a puncture The tip 111 has a connecting rod 113 in the middle, and the matching part 112 at the other end is specifically a baffle.

[0043] In this embodiment, the middle part of the excitation part 132 is pivotally connected to the puncture part 1 through a pivot. One end of the excitation part 132 is provided with a limit hook to limit the retraction of the puncture part 11, and the other end is provided with a release limit hook. The button is provided with a torsion spring 135 that drives the limit hook to be in a limit state on the pivot. ...

Abstract

The invention discloses an integrated puncture and perfusion catheter for abdominal organ transplantation donor perfusion, one end of the integrated puncture and perfusion catheter is provided with a puncture part, and the puncture part comprises a puncture piece, an accommodating channel and a retraction assembly capable of controlling the puncture piece to retract into the accommodating channel; the puncture part is arranged in the containing channel and can stretch out and draw back to enter the containing channel, and the retraction assembly is connected with the puncture part. The catheter has the advantages of being convenient to operate, good in puncture effect, capable of avoiding blood splashing, capable of preventing damage to endangium, capable of effectively improving the perfusion efficiency, capable of guaranteeing the quality of donor organs and the like.

Description

technical field [0001] The invention relates to the technical field of surgical instruments for organ transplant donors, in particular to an integrated puncture perfusion catheter for abdominal organ transplant donor perfusion. Background technique [0002] During donor surgery for abdominal organ donation (such as liver, kidney, pancreas, small intestine, etc.), it is necessary to establish an abdominal viscera perfusion system as soon as possible, and quickly reduce the core temperature of the target organ through efficient perfusion to reduce the warm ischemia time of the target organ. To improve the success rate of transplant surgery, at the same time, it is also necessary to avoid the flow of perfusate into unnecessary organs. The current surgical method is as follows: first expose the abdominal aorta below the superior mesenteric artery, ligate the distal aorta, tie the proximal end with a thread, incise the proximal aortic wall and insert an adult urinary catheter (pr...
