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
Moreover, the length of the gun body of the existing clip applier is fixed. When it is found that the length needs to be increased during the hand-holding process, the clip applier is often pulled out from the patient's body and a longer clip applier is selected again.

Abstract

The invention relates to a clip applier shaft assembly and a medical surgical clip applier. An inner sleeve and an outer sleeve are arranged in a tube body, and a second driving shaft is used for pushing the inner sleeve to move relative to the outer sleeve, so that a gun body of the clip applier can stretch out and draw back; and moreover, the gun body can be reset by arranging a first reset piece for connecting the tube body with the inner sleeve. Therefore, the clip applier shaft assembly and the gun body of the medical operation clip applier can stretch out and draw back, the requirement for length diversification in the operation process is met, operation risks are reduced, and the instrument cost 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...
