Problems solved by technology

[0005] 2. In open surgery and laparoscopic surgery, it is difficult and time-consuming to close the open end with sutured folds, even if positioned at the open end of the intestine and stomach (eg, in the esophagus after gastrectomy)
[0006] 3. In some cases (after esophageal surgery), the anvil needs to be fixed to the end of the catheter to reach the anastomotic line, which results in the transmission of microorganisms in the oral cavity and esophagus to the abdomen, thereby increasing the risk of infection
[0007] The above apps are difficult to use, time consuming, and limited in scope
For example, existing stapler anvils cannot be fixed to the endoscope end for use, making such an application impractical

Abstract

A foldable anvil provides secure anastomosis in circular staplers and has an anvil cap with a main body, a clamping arm configured on the main body, a punch section and a punch surface corresponding to the punch section. The anvil cap includes multiple foldable wings, a command wire connected with the wings, and a wire wrap pulley directing the command wire.

Description

technical field [0001] The invention relates to a circular stapler, which is an automatic suture positioner for digestive system surgery. [0002] In particular, the present invention relates to a foldable anvil top cover, which ensures quick and safe stapling in continuation of providing a circular stapler digestive system. Background technique [0003] Currently, staplers consist of two parts: a body (handle) and an anvil fixed at the end of said body. Even though said circular staplers are available on the market for fast and safe stapling, their use, especially laparoscopically, is very limited due to several disadvantages. In open surgery and laparoscopic surgery, the disadvantages that limit its use are mainly as follows: [0004] 1. In order to position the anvil in the intestine or gastric cavity to be anastomosed, it is necessary to form an independent and large space on the intestinal wall. [0005] 2. In open surgery and laparoscopic surgery, even if positioned...
