Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with specific embodiments.

[0021] Such as figure 1 As shown in the structural diagram of the present invention, the locking device includes a base 3-1 with a groove on it, and the upper part of the limit block 2-1 rotates through the limit block rotation shaft 3-3 connected to the base 3-1. Connected in the groove of the base 3-1, the two hooks 3-2, which are installed on both sides of the limit block and arranged symmetrically, are respectively connected by the rotation of the hook rotating shaft 3-4 connected to the base 3-1. In the groove of the base 3-1, the upper ends of the two tension springs 3-5 arranged symmetrically are respectively hooked in the pin holes at the lower ends of the two hooks and the lower ends are hooked in the bottom ends of the stopper 2-1. On the spring pin shaft 3-6, the axis of the limit block rotating shaft is parallel to the axis of the suspension hook rotating sha...

Abstract

The invention discloses a locking device for a surgical robot quick replacement mechanism, comprising a base, a stop block, two hooks and two tension springs. The base is provided with a groove, the upper part of the stop block is rotatably connected into the groove of the base through a stop block rotating shaft connected to the base, the two hooks which are respectively mounted at both sides ofthe stop block and are symmetrically arranged are rotatably connected into the groove of the base respectively through hook rotating shafts connected to the base, the upper ends of the two symmetrically arranged tension springs are respectively hooked in pin holes at the lower ends of the two hooks, the lower ends of the two tension springs are hooked on a spring pin shaft at the bottom end of the stop block, and the axis of a rotating shaft of the stop block is arranged in parallel to the axes of the hook rotating shafts. The invention has the advantages that: (1) two limit positions respectively correspond to two states of a tool in quick replacement operation, i.e. a tool dismounting state and a tool locking state; and (2) the two limit positions can be randomly switched by being pressed once and can be automatically kept under the spring action without continuously pressing in use.

Description

technical field [0001] The invention relates to a locking device, in particular to a locking device for a quick-change mechanism of a surgical robot. Background technique [0002] Minimally invasive surgery robot system uses slender surgical tools to penetrate into the body through tiny incisions on the surface of the human body for surgical operations. Due to the limitations of different surgical types and various specific surgical operations, it is impossible to use one surgical tool to perform all surgical operations. Under such circumstances, it is necessary to use a quick-change mechanism to quickly and easily replace different surgical tools during the operation. At the same time, the performance of the quick-change mechanism is also an important part of the overall performance of the minimally invasive surgical robot system. Its performance indicators not only affect the use of surgical tools and the entire system, but also directly determine the design indicators an...
