Problems solved by technology

[0003] The handle of a typical endoscopic linear cutting stapler is divided into a movable handle and a fixed handle. By gripping the movable handle, the transmission part is moved to trigger the suturing assembly. Causes false firing, causing the suture components to be scrapped before they are used, and the usage rate of the suture components is low

Abstract

The invention provides a safety device of a straight line cutting stitching instrument under en endoscope. The safety device comprises a fixed handle and a movable handle and further comprises a safety sliding block arranged on the fixed handle, a safety spring connected with the safety sliding block and a handle spring arranged on the movable handle, wherein one end of the handle spring can abut against the top end of the safety sliding block. A blocking part is arranged on the movable handle and a safety button is arranged on the safety sliding block. According to the straight line cutting stitching instrument under the endoscope, due to the arrangement of the safety device, an instrument can be used only by turning on the safety button in the time of operation by working staff, after use of the instrument is finished, the safety button automatically reset, error percussion of a stitching assembly is avoided, and a usage rate of the stitching assembly of the straight line cutting stitching instrument under the endoscope is improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a safety device for a linear cutting stapler under an endoscope. The present invention also relates to an endoscopic linear cutting stapler comprising the safety device. Background technique [0002] During the operation of minimally invasive surgery, a surgical stapler is usually used to connect adjacent parts of the tissue. At present, the commonly used endoscopic linear cutting stapler is in the form of a cutting knife on the surgical fastening device. The staple cartridges move linearly, so as to achieve the purpose of cutting and sealing the sutured tissue when the surgical suturing device is sutured. [0003] The handle of a typical endoscopic linear cutting stapler is divided into a movable handle and a fixed handle. By gripping the movable handle, the transmission part is moved to trigger the suturing assembly. Cause misfiring, cause the suture assembly to b...
