Problems solved by technology

[0003]However, the feeding mode of the clip magazine and the triggering mode of the surgical clips of the existing clip appliers are relatively complicated, and it is often necessary to separate the pushing device and the firing device separately. Operation, increased operation steps, increased surgical risk to a certain extent

Abstract

The invention relates to a clip applier shaft assembly and a medical surgical clip applier. According to the clip applier shaft assembly and the medical operation clip applier, a reset piece is arranged in a tube body; when a driving device of the medical surgical clip applier drives a main shaft to move towards the head end, a second reset piece deforms, and a first reset piece serves as a connecting piece to push a clip pushing assembly to move; then the main shaft makes contact with a percussion assembly and pushes the percussion assembly to move towards the head end, and a third reset piece deforms; and therefore, after final surgical clip percussion is completed and driving is stopped, the reset force generated by the reset piece enables the main shaft, the clip pushing assembly and the percussion assembly to reset. Therefore, according to the clip applier shaft assembly and the medical surgical clip applier, only the driving main shaft is arranged to move, the effects of clip pushing, clip feeding, percussion and device resetting are achieved, the operation process is simplified, and the operation risk is reduced.

Description

technical field [0001] The invention relates to a clip applier shaft assembly and a medical operation clip applier, belonging to the field of medical equipment. Background technique [0002] Endoscopic surgical staplers and surgical clip appliers are known in the art and are used in many different and useful surgical procedures. In the case of laparoscopic surgery, access to the interior of the abdomen is achieved through a narrow tube or cannula inserted through a small entry incision in the skin. Minimally invasive procedures performed elsewhere on the body are often referred to as endoscopic procedures. A tube or cannula device is typically extended into the patient through the entry incision to provide the access port. This port allows the surgeon to insert a number of different surgical instruments through it using a trocar and for performing surgery away from the incision. [0003] However, the feeding mode of the clip magazine and the triggering mode of the surgica...
