Medical surgical operating instrument

Abstract

The invention discloses a medical surgical operating instrument. The medical surgical operating instrument comprises a nail anvil arm and a nail box arm, the nail anvil arm comprises a telescopic arm, a connecting arm and a fixed arm, the inner surface of the telescopic arm is fixedly connected with the connecting arm, the connecting arm is slidably connected with the fixed arm, a plurality of upper matching holes are formed in the surface of the fixed arm, and the connecting arm is in threaded connection with the upper matching holes of the fixed arm through first screws. By using a movable support, the telescopic arm, the connecting arm, the fixed arm and a metal ball of a screw rod, the device can abut against the telescopic arm through the screw rod and the metal ball, so that the included angle between the nail anvil arm and the nail box arm can be adjusted, and the gap of the nail anvil arm and the nail box arm can be changed; and the effective length of the nail box arm is adjusted through the movable support, meanwhile, the effective length of the nail anvil arm is changed through the telescopic arm and the connecting arm, so that the gap between the tail ends of the nail box arm and the nail anvil arm is changed, and the device is more in gap adjusting mode, larger in adjusting range and higher in applicability.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, in particular to a medical surgical instrument. Background technique [0002] Surgical instruments refer to medical instruments used in clinical operations, and staplers are one of them. Staplers can be mainly divided into skin staplers, rectal staplers, circumcision staplers, linear cutting staplers, etc. For example, linear cutting staplers are used for resection and suturing of gastrointestinal tissues. Stapler is a device used in medicine to replace traditional manual suturing. Due to the development of modern technology and the improvement of manufacturing technology, the clinically used stapler is reliable in quality, easy to use, tight, and suitable for tightness, especially its fast suturing and few There are advantages such as surgical complications. [0003] For example, the authorized announcement number is CN106510783B, which discloses a surgical instrument. The surgical...
