Abstract

The application provides a driving device and a stapler for an intracavitary surgical stapler, including a driving handle, a driving structure and a housing, and the driving structure includes a driving link assembly, a clamping driving assembly, a positioning pin driving assembly and a push nail driving Assemblies, the clamping drive assembly drives the clamping push rod to achieve clamping, the positioning pin drive assembly drives the positioning pin push rod to drive the positioning pin, the push pin drive assembly drives the push pin push rod to drive the push pin block, and the drive handle pushes the drive link The rod assembly is moved from the first position to the third position so that the positioning pin drive assembly and the clamping drive assembly move axially. When the drive link assembly is at the first position, the drive link assembly limits the pushing nail drive assembly to The pusher driving assembly is not in contact with the pusher push rod under the drive of the drive handle, and when the drive link assembly is at the third position, the pusher drive assembly pushes the pusher push rod under the drive of the drive handle. The positioning pin, clamping and pushing nail of the stapler are completed by a single handle, and the operation is simple.

Description

technical field [0001] The invention relates to a medical device, in particular to a driving device and a stapler for an intracavity surgical stapler. Background technique [0002] The transverse cutting anastomosis / stapler is mainly used for the creation of anastomotic stoma and the closure of the stump or incision in the digestive tract reconstruction and organ resection surgery where it is difficult to expose the surgical field. At present, the general use process of the transverse cutting stapler is: after the locking handle is positioned to lock the tissue, the firing handle is pushed, the cutter hidden in the staple cartridge assembly is pushed by the central rod driven by the firing handle, and the other side of the tissue to be cut is The anvil and the knife pad that provide the tissue cutting platform, the driven straight cutter cuts off the knife pad during the whole cutting process represents the completion of the cutting task. Compared with the transverse cuttin...
