Abstract

The invention discloses a device for clamping and fast shifting surgical needles, which is used for a robot for minimally invasive surgery, and pertains to the technical field of accessories for minimally invasive surgery. The device comprises a fast-shifting cap, a compression spring, a sliding shaft, a movable pressing board and a surgical needle sleeve, wherein, the fast-shifting cap is sheathed on a frame; a through hole, which is used for installing the compression spring and the sliding shaft and being passed through by the sliding shaft, is arranged at the top of the fast-shifting cap; the compression spring is installed between the sliding shaft and the fast-shifting cap; the sliding shaft is matched with a hole on the frame under the effect of compaction and the fast-shifting cap is fixedly connected with the frame; the movable pressing board is installed at one side face of the fast-shifting cap while a bayonet is arranged at the other side face of the cap; the surgical needle sleeve is placed at the middle part of the movable pressing board, one end of which is locked in the bayonet; and the surgical needle sleeve is tightly clamped by the flexible deformation of the movable pressing board. The device can assemble and disassemble the fast-shifting cap as well as clamp and remove surgical needles of different types conveniently.

Description

technical field [0001] The invention relates to a quick-changing device, which belongs to the technical field of minimally invasive medical auxiliary equipment, in particular, it is used for clamping and quick-changing surgical needles of minimally invasive surgical robots. Background technique [0002] The parts of minimally invasive surgical equipment that may come into direct contact with patients need to be sterilized before surgery. The part to be sterilized needs to be able to be quickly connected and disconnected from the equipment body, so a quick change device is required. Since the minimally invasive surgical robot is an active positioning device, it has high requirements on the rigidity of the structure, and without manual assistance, its terminal structure is more complicated than that of existing surgical equipment. on the surgical robot. In addition, during the operation, when the robot locates the surgical needle to the designated position, it is necessary t...
