Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a smart device for quickly assembling and disassembling tools at the end of an oral craniomaxillofacial osteotomy robot. Background Art

[0002] Oral and craniomaxillofacial osteotomy is a type of surgery used to correct deformities of the oral and craniomaxillofacial skeleton or improve related function and appearance. During the operation, according to the specific surgical plan, the surgeon will make an incision in the mouth or corresponding part of the face to expose the bone that needs to be cut. Specialized osteotomy instruments, such as electric saws and osteotomes, are then used to cut the bone along the predetermined osteotomy line. After cutting, the bone segments are repositioned to the ideal position and fixed with internal fixation materials such as titanium plates and nails to ensure the bone heals in its new position. Finally, the incision is sutured to complete the operation. The oral and craniomaxillofacial skeleton is a complex three-dimensional structure. During surgery, the surgeon must precisely determine the location, angle, and depth of the osteotomy, as well as the direction and distance of bone movement and repositioning. This requires the surgeon to have good spatial imagination and precise operating skills. The surgeon must be able to accurately complete various operations within the limited surgical field of view and operating space to achieve precise reconstruction of the facial skeleton and restore normal facial morphology and occlusal function. To achieve the ideal surgical outcome, surgeons must perform numerous delicate operations. For example, when using micro-titanium plates and nails for bone fixation, they must accurately drill holes and insert screws to ensure stability and reliability. These delicate operations require the surgeon to maintain high concentration for extended periods, which can easily lead to fatigue and affect the accuracy and efficiency of the surgery.

[0003] Multi-degree-of-freedom serial or parallel robotic arms can achieve precise and flexible spatial motion and can realize the desired complex spatial operations through programming, remote operation, and human-machine collaboration. Therefore, robotic arms can effectively reduce the surgical difficulty of oral craniomaxillofacial osteotomy surgery, improve surgical precision, reduce surgical intensity, shorten the surgeon's learning curve, and achieve a uniform level of surgical quality. However, oral craniomaxillofacial osteotomy surgery requires a variety of surgical tools, which have the following technical drawbacks: how to achieve the rapid and precise installation and replacement of multiple surgical tools at the end of the robotic arm is a problem that must be solved; while solving the problem of rapid and precise installation and replacement, the vibration disturbance caused by electric surgical tools must also be considered, so the stability and reliability of the installation must also be addressed; robotic arms cannot be cleaned and sterilized, while surgical tools must remain sterile. Therefore, rapid and precise installation and replacement should not destroy the sterility of the surgical tools, and a sterile barrier should be constructed between the end of the robotic arm and the surgical tools.

[0004] Patent publication number CN218922776U discloses an end-instrument clamping device and an intraocular surgical robot, belonging to the field of surgical instrument technology. The end-instrument clamping device is used in an intraocular surgical robot and includes a mounting base and a clamping mechanism. The mounting base is mounted on the end-instrument clamping device of the intraocular surgical robot. The clamping mechanism is mounted on the mounting base and includes a clamping member. The clamping member is a tubular structure with a mounting channel for an actuator to pass through. The clamping member is used to clamp the actuator, which is used to perform intraocular surgery. The clamping mechanism also includes a positioning member, which is disposed on the clamping member and is used to securely position the actuator within the clamping member. The positioning member is a tubular structure with an inner wall having a tapered surface with a gradually decreasing diameter. As the positioning member moves axially along the clamping member, the tapered surface gradually shrinks, thereby gradually applying pressure to multiple clamping portions of the clamping end until the positioning member can no longer move axially, thereby achieving positioning and clamping of the actuator. This structure has the following technical defects during use: the structure of the synchronous belt and synchronous pulley is relatively large and complex, and cannot meet the technical requirements of rapid replacement and installation of multiple surgical tools and construction of a sterile barrier in oral craniomaxillofacial osteotomy surgery.

[0005] Therefore, how to design a dexterous device for quickly loading and unloading tools at the end of an oral craniomaxillofacial osteotomy robot, which can quickly and accurately install and replace multiple surgical tools at the end of a robotic arm when using a multi-degree-of-freedom motion platform such as a robotic arm to assist in oral craniomaxillofacial surgery, has become an urgent problem to be solved.
