Endoscopic stapling device

Abstract

The invention discloses an endoscopic stapling device, and belongs to the technical field of medical supplies. The endoscopic stapling device comprises a staple bin part, a staple resisting base, an assembly inner core and an assembly outer tube which is connected with the assembly inner core in a sleeving manner, wherein the staple resisting base is a fixed end and is fixedly connected with the left end of the assembly inner core; the staple resisting base comprises a staple resisting base body and support lateral sides which are connected with the two sides of the staple resisting base body;the support lateral sides are positioned above the right end of the staple resisting base body; the staple bin part is a movable end, and is rotatably connected with the support lateral sides throughjaw reset pins; the staple bin part is positioned on the inner sides of the support lateral sides; and opening and closing of the staple bin part is realized through connecting the staple bin part and the assembly outer tube, and the staple bin part is in contact fit with the support lateral sides in a closing state. According to the endoscopic stapling device disclosed by the invention, the staple bin part is the movable end, and the staple resisting base is the fixed end; and because of the characteristic of thinness of the staple resisting base, the staple resisting base is convenient to operate and easily passes through a gap of a narrow and small assembly, and thus, the staple resisting base is applied to complicated, narrow and small assemblies. The endoscopic stapling device has the advantages that the device has high operation passing ability, is convenient for operation of doctors and improves the surgical quality.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to a laparoscopic stapler. Background technique [0002] Laparoscopic staplers play the most critical role in surgery. Due to the limitation of the space in the abdominal cavity or the thoracic cavity, the traditional endoscopic linear stapler cannot fully and effectively reach the required surgical site for clamping, transection, and anastomotic tissue. Due to the limitation of the space in the abdominal cavity or the thoracic cavity, the space of the stripped components is limited, and the space for passing the stapler is limited. At present, the existing laparoscopic linear cutting stapler components in the market are the movable end of the nail seat and the fixed end of the staple cartridge part, which are used to close and clamp the tissue. [0003] The fixed end of the staple cartridge assembly is rigid enough to be connected and operable, and the operation feels go...

AI Technical Summary

Problems solved by technology

For example, when cutting blood vessel C and other tissues, blood vessel C will be provoked by the cross-section of staple cartridge A, and there will be certain surgical risks due to the influence of tissue traction after cutting

However, the structure of the supporting ear D on both sides is weak, which cannot meet the actual use conditions. After the movable end and the fixed end are closed, they cannot be well aligned. In this way, during the forming process of the staple, it will lead to poor forming of the staple and serious medical accidents such as leakage.
