Description

technical field [0001] The invention belongs to the field of medical instruments, in particular to a clip applier capable of continuously releasing hemostatic clips. Background technique [0002] The hemostatic clip is a new type of surgical instrument that has been widely adopted and used by medical institutions around the world in the past ten years. It greatly reduces the operation risk and operation time, and achieves minimal trauma to the patient. With the use of a large area, new requirements and new concepts have been proposed by professional doctors in major medical institutions: "It is best to realize continuous clamping of hemostatic clips by clip appliers", so that doctors do not need to leave the human body after using clip appliers to enter the human abdominal cavity , continuous and fast operation, and can quickly and effectively operate the forceps with one hand, and can ensure the smooth completion of one operation. [0003] In the prior art, there are two t...

Problems solved by technology

As far as simple laparoscopic surgery is concerned, six hemostatic clips need to be clamped continuously at one time, and the above action must be repeated six times. This is obviously troublesome and time-consuming on the operating table, and it will also delay the operation time

[0004] The other is a clip applicator that sends multiple hemostatic clips in one go (for example, the Chinese patent application whose publication number is CN103637827A), this clip applier is to pack 10-20 hemostatic clips inside, and these hemostatic clips can Clipping, but when the hemostatic clip in the warehouse is clipped, the clip applicator can no longer be used, because the hemostatic clip cannot be inserted

It is obviously wasteful to discard the whole pair of clip appliers
