Abstract

The invention provides a transverse intracavity stitching instrument with a sealing structure. The stitching instrument comprises an end executor, a connecting outer tube and a driving assembly at least partially arranged in the connecting outer tube, and is characterized in that the end executor comprises a nail bin shell, a stitching nail and a nail pushing block; the driving assembly comprisesa driving push rod and a driving shell; the driving push rod is used for driving the nail pushing block to push the stitching nail upwards; the driving shell is used for driving the nail bin shell; the near end of the driving shell is connected with a hollow driving connecting rod, and the driving push rod sequentially penetrates through an inner cavity of the hollow driving connecting rod and aninner cavity of the driving shell; a first sealing ring is arranged between the driving push rod and the hollow driving connecting rod; and a second sealing ring is arranged between the hollow drivingconnecting rod and the connecting outer pipe. The driving mechanism of the transverse stitching instrument is improved to be connected and driven by adopting a cylindrical element, and a sealing device is correspondingly arranged at the key part, so that the transmission is not influenced, the sealing property can be ensured, and the transverse stitching instrument is suitable for endoscopic surgery and the air leakage condition in the surgery process is prevented.

Description

technical field [0001] The invention relates to a medical instrument, in particular to a sealing structure and a stapler for endoscopic surgery. 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 cutting stap...
