Embodiment 1

[0026] like figure 1 As shown, the present embodiment discloses a ureteral stapler, comprising a fixed clip 2 and a built-in tube that can be inserted into the ureter, the fixed clip 2 is used to fixedly connect the ureter and the built-in tube, and the built-in tube includes a bulge that is in close contact with the ureter. Part 1, the inner tube and the fixing clip 2 are made of degradable materials.

[0027] Further, the built-in tube also includes parallel portions 3 disposed at both ends of the raised portion 1, the parallel portion 3 is provided with an opening at one end away from the raised portion 1, and the cross-sectional diameter of the opening is smaller than the cross-sectional diameter of the parallel portion, so as to facilitate An internal tube is placed into the ureter.

[0028] Further, the material of the built-in tube and the fixing clip 2 is any one of polylactic acid material, nano-degradable fiber, chitosan, polytetrafluoroethylene, and gelatin sponge,...

Embodiment 2

[0031] In the case of adopting the technical solution of Embodiment 1, as figure 1 As shown, a plurality of fixing holes 4 are evenly distributed on the parallel portion 3 of the built-in tube. like figure 2 , image 3 As shown, the fixing clip includes a first fixing plate 201 and a second fixing plate 202, one end of the first fixing plate 201 is connected with one end of the second fixing plate 202, and the other end of the second fixing plate 202 is provided for fixing The hook 203 at the other end of the first fixing plate 201, there is a accommodating cavity 204 between the first fixing plate 201 and the second fixing plate 202 that can be sleeved on the outside of the ureter, and a plurality of fixing pins 205 are arranged in the accommodating cavity 204, The fixing pin 205 cooperates with the fixing hole 4 on the parallel part 3 of the built-in tube to realize the fixed connection between the ureter and the built-in tube, figure 2 It is a schematic diagram of the ...

Embodiment 3

[0036] In the case of adopting the technical solution of Embodiment 1, as Figure 4 As shown, the ureteral stapler includes two fixing clips 2, and the accommodating cavity 204 between the two fixing clips 2 is connected by a biofilm 5, and the biofilm 5 is in close contact with the built-in tube. The biofilm 5 is distributed with drugs for promoting ureteral healing.

[0037] Further, the biofilm material is any one of polyhydroxybutyrate, collagen, fibrin, and biogel, but is not limited thereto.

[0038] The ureteral stapler provided in this embodiment can promote the postoperative recovery of the ureter by distributing a drug that promotes ureteral healing on the biofilm 5, and the biofilm 5 is placed close to the built-in tube, which can prevent the ureter from retracting.

Abstract

The embodiment of the invention discloses a ureter anastomat and a use method thereof. The ureter anastomat comprises a fixed clamp and a built-in tube which can be inserted into a ureter, wherein thefixed clamp can fixedly connect the ureter with the built-in tube, the built-in tube comprises a hunched portion tightly in contact with the ureter, and the built-in tube and the fixed clamp are madefrom a degradable material. The ureter anastomat provided in the embodiment is simple in structure, convenient to operate and capable of saving time and labor, and the current problems of anastomoticstenosis, inconvenient operation and time and labor waste during laparoscopic suture with a needle and a suture are solved. The built-in tube and the fixed clamp in the ureter anastomat are made fromthe degradable material, so that the ureter anastomat does not need additional suture and ureter stent indwelling and taking through operations. By adopting the ureter anastomat, a ureter breaking away under laparoscopy can quickly anastomose, the operation in the whole process is convenient, the working efficiency of doctors is greatly improved, the pressure of operation doctors is reduced, andpostoperative revival and rehabilitation are facilitated.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a ureteral stapler and a method for using the same. Background technique [0002] When performing laparoscopic needle and thread suture, due to the narrow field of view under laparoscope, the needle holder is easy to slip off, and the operation of knotting and thread trimming is cumbersome. Even experienced physicians are still difficult to suture, which takes a long time. In order to be convenient to use, people have developed staplers, but most of the existing staplers are aimed at blood vessels and intestines, and there is a lack of staplers specially used for ureter. Time consuming problem. SUMMARY OF THE INVENTION [0003] The purpose of the embodiments of the present invention is to provide a ureteral stapler and a method for using the same, so as to solve the problems of narrow anastomotic stoma, inconvenient operation, time-consuming and labor-intensive laparos...
