Nail bin assembly of endoscope cutting stapler

Abstract

The invention relates to a nail bin assembly of an endoscope cutting stapler. The assembly adopts the technical characteristics that: the nail bin is bounded by a nail storage hole at the aftermost part of the nail bin, the front part is the wide part of the nail bin, and the rear part is the narrow part of the nail bin; adopts the technical characteristics that: the position of the nail bin framecorresponding to the wide part of the nail bin is the wide part of the nail bin frame, and the position corresponding to the narrow part of the nail bin is the narrow part of the nail bin frame; adopts the technical characteristics that: the left side and the right side of the position, corresponding to the narrow part of the nail bin, of a nail anvil assembly are provided with nail anvil fins; realizes the technical scheme of enhancing the rigidity of the nail bin frame; realizes the technical scheme that the thickened nail anvil fins enhance the acting force for blocking the narrow part ofthe nail bin frame from moving left and right relative to the nail anvil assembly; achieves the technical effect of improving the corresponding positioning accuracy between a forming groove on the contact surface of nail anvil tissues and the nail storage hole on the contact surface of the nail bin tissues; and achieves the technical effect that an actuator assembly with the diameter of 10mm can be manufactured and a puncture outfit with the diameter of 10mm can be shared with other endoscopic surgical instruments.

Description

technical field [0001] The present invention relates to the staple cartridge assembly of the laparoscopic cutting stapler used in laparoscopic surgery, in particular to the staple cartridge assembly of the laparoscopic cutting stapler used in laparoscopic surgery, and in particular to the staple cartridge assembly used in thoracoscopic surgery. Cartridge assembly of a laparoscopic cutter stapler used in surgery. Background technique [0002] In laparoscopic surgery and thoracoscopic surgery, various manual, electric and surgical robotic endoscopic cutting and stapling devices are usually used for cutting and anastomosis in the abdominal cavity and thoracic cavity, which can reduce surgical trauma and shorten The operation time is improved, and the operation quality is improved. [0003] Various laparoscopic cutting staplers introduced in US20100200639A1 and US20170095250A1 include an execution component, an extension component and an operation component. The extension comp...

Problems solved by technology

The first unsatisfactory part of the endoscopic cutting staplers of the above two styles is that the cross section in the U-shaped groove of the staple cartridge frame is the same in the front and back direction. First, the rigidity of the staple cartridge frame is small and easy to install. Deformation occurs; second, reduce the thickness of the anvil wings, reduce the force that the anvil wings block the narrow part of the nail cartridge frame from moving left and right relative to the nail anvil assembly, thereby reducing the forming groove and the staple cartridge on the contact surface of the nail anvil tissue. The corresponding positioning accuracy of the positions of the nail storage holes on the tissue contact surface reduces the surgical quality of the laparoscopic cutting stapler; third, the diameter of the actuator assembly of most laparoscopic surgical instruments is 10mm, which is used for punctures with a diameter of 10mm However, the cross-section in the U-shaped groove of the staple cartridge rack is the same in the front-back direction. It is difficult to make an executive component with a diameter of 10 mm for an endoscopic cutting stapler. It is difficult for an endoscopic cutting stapler to share a diameter of 10 mm with other endoscopic surgical instruments. 10mm trocar

The second unsatisfactory point of the above two styles of laparoscopic cutting staplers is that the injection molded parts of the staple cartridges formed by the buckle mechanism between the staple cartridge and the staple cartridge rack need to be processed with a core-pulling mold, which will affect the processing on the one hand. Quality, on the other hand increases the processing cost
