A multi-angle bending linear stapler

Abstract

The present invention relates to the technical field of linear staplers, and discloses a linear stapler bent at multiple angles, including a firing case, one end of the bottom of the firing case is fixedly connected with a hand grip, and one side of the hand grip is rotatably connected with a firing handle. The middle part of the firing handle is plugged with a button, the end of the button is fixedly connected with a rotating sleeve, and the shaft of the rotating sleeve is rotatably connected with a first connecting rod and a second connecting rod, and the tops of the other ends of the first connecting rod and the second connecting rod are fixed Extension rods are connected, the tops of the extension rods are rotatably connected with telescopic rods, and the tops of the telescopic rods are rotatably connected with push rods, and the side wall on one side of the firing shell is provided with a third slide rail, and the third slide rail is slidingly connected with a limiting frame. The device realizes the rotation of the staple cartridge bracket in four directions by turning the first knob and the second knob, the bending angle is changeable and easy to operate, the bending angle adjustment accuracy is high, and the external force operation is avoided to increase the risk of surgery, and it is convenient for operation. Suture, with little limitation.

Description

technical field [0001] The invention relates to the technical field of linear staplers, in particular to a linear stapler bent at multiple angles. Background technique [0002] The stapler is the first stapler in the world. It has been used for gastrointestinal anastomosis for nearly a century. It was not until 1978 that the tubular stapler was widely used in gastrointestinal surgery. It is a device used in medicine to replace traditional manual suturing. Due to the development of modern technology and the improvement of production technology, the clinically used stapler is reliable in quality, easy to use, tight and suitable for tightness. [0003] The current linear cutting staplers all have the function of bending in one direction, but the bending direction is single and the bending angle is fixed. Most of the end of the staplers need to be pulled by external instruments to achieve the bending at a fixed angle. During the operation, both the stapler and the medical instr...
