Abstract

The invention discloses a safety device of clip applier for medical use, which consists of a casing, and a percussion handle, a connecting rod, a shifting block and a safety block rotating against the casing respectively, wherein the safety block is mounted with a push rod at the position far from the shaft thereof; with the push rod, the safety block can rotate from the first limit position to the second limit position along the shaft; the percussion handle and connecting rod are linked in rotation; the connecting rod is provided with a first limit structure, and the shifting block is provided with a second limit structure that collides with the first limit structure for limiting; the shifting block is further provided with a first limit part with a slip groove structure; the first limit part of the shifting block and the push rod can rotate the clamp to make the first limit part rotate along with the safety block, thereby opening or closing the safety block. The safety device can guarantee safety well and move along a definite direction during operation, which can effectively prevent the clamp from the sliding caused by false percussion of instrument. Besides, the safety device has a light structure and favorable stability, and can give out clear sound prompts.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a medical clip applier with a safety device. Background technique [0002] During surgical operations, such as abdominal surgery, shock or even death due to bleeding is one of the main risks of the operation. Therefore, stopping the bleeding as much as possible is a major factor for the ultimate success of the operation. Traditional surgical methods use ligation, suture or compression of blood vessels to achieve hemostasis. In recent years, clip applicator hemostasis is a new type of hemostasis method, which greatly improves the operation speed compared with traditional methods, and the speed of operation is directly related to the degree of bleeding. How many. Because the use of clip applicator greatly reduces the amount of bleeding in the operation, avoids infection and reduces the risk of operation, especially plays a very important role in minimally invasive surg...
