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] like 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 inserting...

Abstract

The invention discloses a fast-locking detachable surgical mechanical device. One end of the base is installed on the manipulator, the base is provided with a fixed rod, and the free end of the fixed rod forms an enlarged part. The first guide cavity that can partially accommodate the guide is formed, and the first locking screw sleeve that forms a limit relationship with the enlarged part is sleeved on the fixed rod; the guide includes a guide rod for partially inserting into the guide cavity, fixed on the guide The second lock screw sleeve on the rod and the guide bracket for installing the surgical tool at the end of the guide rod away from the base, the first lock screw sleeve is threadedly connected with the second lock screw sleeve; the guide bracket includes a vertical The sleeve used to lock the surgical tool is set; the present invention forms a tight rigid connection through the mutual nesting of two locking nuts, guide rods, and fixed rods, which can improve the bearing capacity of the guide and ensure that the surgical tool There will be no slight shaking of the guide bracket during the 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...
