Tool jig for assembling surgical robot instrument connecting mechanism

Abstract

The invention discloses a tool jig for assembling a surgical robot instrument connecting mechanism. The tool jig comprises a rectangular base, a stand column and an assembling base, a circular counterbore is formed in the upper end face of the assembling base, and a positioning hole penetrating through the lower end face of the assembling base is formed in the bottom face of the counter bore; inserting holes penetrating through the left end face and the right end face of the assembling base are formed in the opposite inner walls of the left side and the right side of the upper end of the counter bore, and a plurality of blocking strips are inserted into the inserting holes of the assembling base; a vertical material ejecting block is inserted into the positioning hole of the assembling base; and the lower end of the ejecting block is inserted into the base; driving wheels abut against the positions, between the base and the assembling base, of the left side wall and the right side wall of the ejecting block, supporting columns are formed on the left side wall and the right side wall, close to the outer edges of the lower ends of the driving wheels, of the ejecting block and inserted into the driving wheels, supporting shafts are formed in the circle centers of the driving wheels, and the outer ends of the supporting shafts extend out of the side walls of the assembling base tobe fixedly sleeved with inclined connecting rods.

Description

technical field [0001] The invention relates to the technical field of medical equipment, and more specifically relates to a tooling fixture for assembling a connecting mechanism of an instrument of a surgical robot. Background technique [0002] During laparoscopic surgery, it is necessary to find a suitable connection mechanism between the laparoscopic surgical robot instrument and the instrument base to form a docking between the laparoscopic surgical robot instrument and the instrument base. The patent No. 201611257011.3 proposes a It is used for the connection mechanism of robotic instruments in laparoscopic surgery; the mechanism is composed of the lower cover of micro-instruments, the upper cover of micro-instruments, springs and limit screws, the lower cover of micro-instruments is rectangular, the upper cover of micro-instruments is circular, and the lower cover of micro-instruments Placed in the upper cover of the micro-device; the spring is arranged between the up...

[0002] During laparoscopic surgery, it is necessary to find a suitable connection mechanism between the laparoscopic surgical robot instrument and the instrument base to form a docking between the laparoscopic surgical robot instrument and the instrument base. The patent No. 201611257011.3 proposes a It is used for the connection mechanism of robotic instruments in laparoscopic surgery; the mechanism is composed of the lower cover of micro-instruments, the upper cover of micro-instruments, springs and limit screws, the lower cover of micro-instruments is rectangular, the upper cover of micro-instruments is circular, and the lower cover of micro-instruments Placed in the upper cover of the micro-device; the spring is arranged between the upper cover of the micro-device and the lower cover of the micro-device, and the limit screw is used to limit the upper cover of the micro-device and the lower cover of the micro-device; when this part is installed, use Manual assembly. During manual assembly, it is necessary to press the lower cover of the micro-device into the upper cover of the micro-device, and then install the limit screw. This manual installation is laborious and troublesome; it is necessary to design related fixtures to assist in the installation, so as to facilitate the connection mechanism of the device assembly
