Problems solved by technology

In order to avoid the interference between the feeding chuck and the clip behind it when the driving mechanism is backed up, the feeding chuck is often small in size and thin in thickness, and is generally a thin sheet. Such a structure may make the feeding of the clip unstable and the strength of the feeding chuck is insufficient. , it is easy to find fractures during the movement, so that the clip applier cannot work normally

Embodiment Construction

[0081] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0082] The user of the surgical instrument may be a clinician, a doctor who manipulates the surgical instrument during surgery to perform surgery. The terms "proximal", "posterior" and "distal", "anterior" are used herein with respect to the clinician manipulating the surgical instrument. The terms "proximal" and "posterior" refer to the part relatively close to the clinician, and t...

Abstract

The clip applier comprises a transmission mechanism, and the transmission mechanism comprises a switching mechanism, a clip feeding driving mechanism, a jaw driving mechanism and a clip pushing driving mechanism; the switching mechanism is connected with the clamp feeding driving mechanism, the jaw driving mechanism and the clamp pushing driving mechanism. The switching mechanism abuts against the actuating piece and is used for receiving the power. Under the action of the actuating piece, the switching mechanism drives the clamp feeding driving mechanism to execute the clamp feeding action, drives the jaw driving mechanism to execute the jaw closing action and drives the clamp pushing driving mechanism to execute the clamp pushing action according to a preset sequence. The number of the actuating piece is one. According to the clip applier, one trigger drives the three driving mechanisms to achieve three functions in order, so that it can be effectively guaranteed that the driving mechanisms do not interfere with one another, and the reliability and safety of the clip applier are improved.

Description

technical field [0001] The present invention relates to a clamp applier. Background technique [0002] In human surgical operations, such as abdominal surgery, a major factor for the ultimate success of the operation when trying to prevent bleeding is to apply clamps. [0003] Existing clamp appliers generally include an operating assembly, an elongated shaft extending from the operating assembly along a distal end, and a jaw assembly disposed at the distal end of the elongated shaft, the jaw assembly including a pair of jaws, the jaws defining a channel for To accommodate surgical clips. [0004] The operating assembly includes a trigger, and a transmission mechanism driven by the trigger is accommodated in the operating assembly to perform the clip feeding action, the clip applying action and the clip pushing action so as to realize the continuous firing function of the clip applying pliers. In order to facilitate the doctor to operate the clip applier and save the docto...
