A quick changing device for a surgical instrument

Abstract

The invention relates to a quick changing device for a surgical instrument, which realizes quick connection and disassembly between the surgical instrument and the end of a robot arm. The quick changing device comprises a mounting base, a mounting joint, a positioning mechanism and a locking mechanism. The positioning mechanism comprises a first positioning part and a second positioning part matching the same, wherein the first positioning part and the second positioning part are respectively arranged on the mounting base and the mounting joint; the locking mechanism includes a first connectordisposed on the mounting joint, and a control device and a second connector disposed on the mounting base. The control device is configured to control the second connector to be locked with the firstconnector so that the first positioning portion and the second positioning portion remain in mating contact, thereby realizing the assembly between the mounting joint and the mounting base. The control device is further configured to control the second connection member and the first connection member to be unlocked so that the first positioning portion and the second positioning portion are in adetachable state, thereby realizing unloading between the mounting joint and the mounting base.

Description

technical field [0001] The invention relates to the technical field of medical instruments, and particularly designs a quick-change device for surgical instruments. Background technique [0002] With the continuous development of robot technology, minimally invasive surgery is gradually entering the public's field of vision in a form different from the traditional one. The precise and efficient surgical implementation process is reflected in all aspects of medical treatment, and the medical treatment environment of patients has also been improved. It has been greatly improved, and the level of modern medical technology has also moved towards a new level. Research on related fields of minimally invasive surgery combined with robotic technology is also an important part of the development of modern medicine. [0003] Minimally invasive surgery is currently the most commonly used method of minimally invasive surgery. Research on its combined application with robotic technology...

Problems solved by technology

[0005] For example, the Chinese patent application CN106344161A discloses a quick-change mechanism for the terminal tool of a minimally invasive spinal surgery robot, which can realize the rapid installation and disassembly of the terminal instrument during the operation. However, the locking operation process is cumbersome and difficult for medical staff to implement quick operation

Another Chinese patent application CN106102642A discloses a technology and method of a shell surgical sleeve installation part, which can realize the installation and disassembly of the surgical sleeve during the operation, but its structural design makes it necessary to operate the unlock button to realize the surgical sleeve. In addition, the technical structure disclosed in this patent requires a large space to realize the layout of the mechanism, which makes it difficult to implement the compact design of the entire structure.
