Embodiment 1

[0031] A fast-locking detachable surgical mechanical device in this embodiment includes a base 1 , a guide 2 and a surgical tool 3 . One end of the base 1 is installed on the manipulator to facilitate the manipulation of the device. The surgical tool 3 in this embodiment uses a thoracolumbar opening circuit opener, which is an important surgical tool in spinal surgery and is used to pierce the cortical bone and cancellous bone, open the Nail channel.

[0032] Such as figure 1 As shown, the base 1 is provided with a fixed rod 11, the free end of the fixed rod 11 forms an enlarged portion 111, and the end surface 1111 of the enlarged portion 111 is provided with an opening to form a first guide cavity 112 that can partially accommodate the guide 2 inwardly. That is, the first guide cavity 112 is hollow; the fixed rod 11 is sleeved with a first locking screw sleeve 12 that forms a limit relationship with the enlarged portion 111; the guide 2 includes a guide for partially insert...

Abstract

The invention discloses a detachable surgical mechanical device capable of being locked quickly. One end of a base is installed on a mechanical arm, a fixing rod is arranged on the base, an expandingpart is formed at the free end of the fixing rod, an opening is formed in the first end face of the expanding part, a first guide cavity capable of partially containing a guider is formed inwards, andthe fixing rod is sleeved with a first locking threaded sleeve forming a limiting relation with the expanding part; the guider comprises a guide rod used for being partially inserted into the guide cavity, a second locking threaded sleeve fixed to the guide rod and a guide support arranged at the end, away from the base, of the guide rod and used for installing a surgical tool, and the first locking threaded sleeve is in threaded connection with the second locking threaded sleeve; the guide support comprises a sleeve which is vertically arranged and is used for locking the surgical tool; through mutual nesting of the two locking threaded sleeves, the guide rod and the fixing rod, tight rigid connection is formed, the bearing capacity of the guider can be improved, and it is guaranteed that the guide support cannot slightly shake when the surgical tool is used for surgical operation.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to the field of surgical robot medical instruments, in particular to a fast-locking detachable surgical mechanical device. Background technique [0002] With the continuous development of medical technology, surgical robots are more and more widely used. The end of the surgical robot is generally equipped with specific surgical tools, such as openers, lumbar openers, thoracic openers, etc. [0003] The end of the robot has particularly high requirements for the fixing, loading and unloading of surgical tools. It needs to be quickly installed and disassembled during the operation, and it needs to be assembled firmly and with high precision. Some existing connection mechanisms cannot combine the two points of fast installation and positioning accuracy well, and they often lose sight of the other, which makes the doctor feel poor during the operation and affects the quality of the o...
