Abstract

The invention discloses a laparoscopic cutting stapler, which comprises an executive assembly, a jaw direction adjustment mechanism and a stapler driving part; the jaw direction adjustment mechanism comprises a joint knob, a main turntable, a shrapnel assembly, a slave turntable, a ring gear, and a transmission shaft , pin shaft, swivel head, adjusting sleeve and 2 joint push rods; the main turntable is provided with a main boss; the slave turntable is provided with a mounting position, a slave boss and a pin hole; the shrapnel assembly includes two elastically set snaps The ring gear is fixed in the rotating head, and its inner ring is provided with evenly distributed teeth; when the joint knob is turned to adjust the jaws to turn, the shrapnel assembly is snapped into the ring gear in time, limiting the rotation from the turntable, effectively ensuring the operation For the problem of jaw swing back during the process, it is easier and labor-saving to operate the adjustment mechanism of the jaw direction; the sound from the beating of the shrapnel makes the jaw direction adjustment mechanism of the stapler have dual reminder effects of feeling and sound.

Description

technical field [0001] The invention relates to a surgical medical instrument, in particular to a laparoscopic cutting stapler capable of bidirectional locking in multiple positions, belonging to the technical field of medical instruments. Background technique [0002] The application number of the Chinese invention patent "Cutting Stapler Suitable for Minimally Invasive Surgery" is CN201310263622.9, and the following is briefly described as Patent 1, which discloses a surgical instrument. The rotating joint knob drives the joint base to rotate synchronously, and the 2 A pin shaft drives two joint push rods to slide back and forth, so that the two joint connecting plates inside the executive component drive the jaws to rotate and adjust around the hinge pins, and the top ball of the positioning bead is embedded in the joint seat for corresponding positioning under the action of the spring force. In the groove, the positioning beads block the joint seat by means of friction a...
