Abstract

The invention discloses a rapidly dismountable handle. The handle comprises a mounting base, a trephine sleeve, stop levers, a rotary switch and a positioning rod, wherein the trephine sleeve is fixedto the mounting base and is coaxial with the mounting base, at least two stop levers are arranged on the peripheral wall of the mounting base, a mounting hole is formed in the trephine sleeve in theaxial direction, a working hole coaxial with the mounting hole is formed in the mounting base, a positioning rod mounting through hole is formed in the trephine sleeve in the radial direction, the positioning rod is connected with the positioning rod mounting through hole in an inserted mode, the trephine sleeve is sleeved with the rotary switch, a positioning rod guide groove and a positioning rod mounting groove are formed in the rotary switch, and the upper end of the positioning rod is in sliding fit with the positioning rod guide groove; when the positioning rod is located at one end, connected with the positioning rod mounting groove, in the positioning rod guide groove, the lower end of the positioning rod extends into the mounting hole; and when the positioning rod is located at the other end of the positioning rod guide groove, the lower end of the positioning rod moves into the positioning rod mounting through hole. By using the rapidly dismountable handle, the trephine can be rapidly mounted and dismounted, and the operation efficiency is effectively improved.

Description

technical field [0001] The invention relates to a handle, in particular to a handle that can be quickly disassembled and assembled. Background technique [0002] The ring saw is an instrument that must be used in minimally invasive surgery. It is necessary to use ring saws of different diameters during the operation, but the ring saw itself does not have a handle, and the handle needs to be installed separately. The process is very troublesome and affects the speed of the operation. Therefore be badly in need of developing a ring saw handle that can be disassembled quickly. Contents of the invention [0003] The purpose of the present invention is to provide a handle that can be quickly disassembled to solve the technical problems in the prior art, which can realize the rapid installation and disassembly of the ring saw, and effectively improve the operation efficiency. [0004] The invention provides a handle that can be quickly disassembled, including a mounting base, ...
