Problems solved by technology
This kind of joint fixed by multiple screws is difficult to be accepted in the operating room because it consumes the doctor's ineffective work time
Especially considering issues such as disinfection and sterilization, the robot is wrapped with a layer of disinfection curtain during the operation, which is a critical factor in clinical acceptability for orthopedic operations where surgical tools at the end of the robot need to be replaced frequently during the operation. Big challenges will also limit the clinical promotion of orthopedic surgical robots

Embodiment Construction
[0030] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0031] see Figure 1 to Figure 5 , as shown in the legend therein, a quick-change mechanism for an end tool of an orthopedic surgery assisting robot is used to quickly disassemble and assemble a surgical tool mounted on the end of a robot, the quick-change mechanism includes a locking assembly, and the locking assembly includes :
[0032] The flange 10 at the end of the robot, the free surface of the flange 10 at the end of the robot constitutes the first positioning surface;
[0033]The locking pin 20, the locking pin 20 is located on the above-mentioned first positioning surface, and the locking pin 20 has a first locking surface 21, a first connecting surface 22, a se...

The invention discloses a rapid replacing mechanism for an orthopedic surgery assisting robot end tool and a rapid replacing method. By using a locking pin, a locking groove, a stopping part and elastic parts in a combined mode, the locking groove tightly presses the locking pin on the stopping part under the action of a spring force so as to achieve limiting, relative to the locking groove, of the locking pin in the groove depth direction; meanwhile, the locking pin is in inclined surface connection with the locking groove so as to achieve limiting, relative to the locking groove, of the locking pin in the groove length direction, by overcoming the acting force of the springs under the exogenic action, unlocking of the locking pin and the locking groove in the groove depth direction can be achieved, then unlocking in the groove length direction is conducted, and rapid dissembling and assembling of the locking pin and the locking groove are achieved. The robot end and the surgical tool can be disassembled and assembled rapidly, and therefore the adaptability and acceptability of an orthopedic surgery robot in an operating room are improved.
Description
technical field [0001] The invention relates to the field of medical equipment, in particular to a quick-change mechanism and a quick-change method for end tools of an orthopedic surgery auxiliary robot. Background technique [0002] The orthopedic surgical robot is one of the earliest surgical robots to be researched and applied in the medical field, and it is also a surgical robot that has been studied more at home and abroad. ) clinical license. [0003] During orthopedic surgery, robotic end-of-surgery tools will need to be replaced frequently according to surgical needs. For this reason, in the design of orthopedic surgery robots, the end connections of the robots are all designed as industrially common flange structures for the replacement of surgical tools. This multi-screw-fixed joint is difficult to be accepted in the operating room because of the waste of doctor's ineffective work time. Especially considering issues such as disinfection and sterilization, the ro...
