Background
With the increasing concern of people on their health problems, the need for using robotics to assist surgery in specific scenes is increasing. The surgical robot needs the mechanical arm and the surgical instrument tool to cooperate with each other to use in the using process, so as to help a doctor to complete the operation, however, most of the surgical instruments cannot be directly assembled at the tail end of the mechanical arm, and a corresponding adapter fitting needs to cooperate with each other to use, and the adapter fitting for connecting the mechanical arm and the surgical instrument tool is called a quick-assembly flange.
The existing fast-assembly flange mechanism is mostly designed in a dovetail groove mode, the design mode is high in processing difficulty and low in processing precision, and the installation precision is possibly reduced due to the error of the processing precision. After the primary assembly is finished, secondary fastening is required to be carried out through locking mechanisms such as bolts, the installation process is not simple and convenient enough, and much time can be wasted in the operation process. In addition, in the actual use process, a scene of repeatedly disassembling and assembling the surgical instrument exists, and if the surgical instrument needs to be disassembled, certain difficulty exists, and time is wasted.

Further, the locating pin is arranged in a locating pin hole of the fast-assembly base.
Furthermore, the locking ring is of an annular structure with a plum blossom annular through hole in the center, the lower half portion of the central inner wall of the locking ring is provided with internal threads for matching with external threads of the fast-assembly base, and one end of an opening of the locking ring in the movement direction is standardized and is provided with a stop block structure in circumferential distribution.
Furthermore, the upper surface of the locking ring is provided with an arc-shaped non-return groove for installing a non-return mechanism, and the radius of the outer ring of the arc-shaped non-return groove is gradually reduced.
Furthermore, the locking ring upper cover is of a disc structure with a hole at the center, and the lower surface of the locking ring upper cover is provided with tenons distributed in a circumferential manner, and the tenons are matched with the arc-shaped non-return grooves of the locking ring to limit the relative rotation of the locking ring upper cover and the locking ring.
Further, the backstop mechanism comprises 3 groups of spring-driven backstop cylinders with backstop cylinder guide, wherein the backstop cylinders are circumferentially arranged in the locking mechanism.
Furthermore, the non-return cylinder is matched with the inner wall of the non-return groove of the locking mechanism, the outer wall of the fast-assembly base and the non-return cylinder in a guiding mode.
Furthermore, one side of the non-return cylinder guide is provided with a cylinder projection structure for standardizing the displacement of the non-return spring; the other side is provided with a semicircular groove which is used for matching with the non-return cylinder.
Furthermore, one end of the non-return spring is tightly pressed with the inner wall of the non-return groove, and the other end of the non-return spring is matched with the cylindrical protrusion structure guided by the non-return cylinder.
Furthermore, the release ring is a thin-wall annular structure with anti-skid insections on the outer side, 3 raised structures distributed in a circumferential manner are arranged in the release ring, and a round blind hole is formed in one side of each raised structure and used for being matched with a release spring; the raised structure cooperates with the non-return groove on the locking ring to secure the release ring and the locking ring and to define the rotational degree of freedom of the release ring relative to the locking ring.
Furthermore, the release spring is guided to be a square round-corner sheet, and one side of the release spring is provided with a square long-strip protruding structure which is used for matching with the mounting hole on the locking ring and limiting the radial displacement of the release spring; the other side is provided with a round blind hole which is used for matching with a release spring.

The invention discloses a realization principle of a quick-mounting flange for an orthopedic surgery robot with a non-return mechanism, which comprises the following steps: 1. the realization principle of the non-return mechanism is that the friction force between the non-return cylinder and the two side walls prevents the loosening direction of the locking mechanism from rotating by changing the size of the gap of the non-return groove: firstly, the non-return spring drives the non-return cylinder to be attached to two side walls; secondly, due to the loosening and rotating trend of the locking mechanism, the non-return cylinder generates a movement trend in the direction of reducing the gap of the non-return groove. Due to the rigid structure of the non-return cylinder and the non-return groove, the contact pressure between the non-return cylinder and the two walls is increased, and the increase of the friction force among the non-return cylinder, the quick-mounting base and the locking ring is initiated. Finally, the non-return cylinder is mechanically locked at the initial position, and the loosening and rotation of the locking ring are inhibited; 2. the release mechanism is realized by pushing the non-return cylinder out of the matching state with the quick-assembly base through the movement of the tenon on the release ring before the non-return mechanism takes effect. At the moment, the single matching of the non-return cylinder and the non-return groove can not cause mechanical locking due to friction, and the loosening and rotation of the locking ring can occur; 3. the operation component is pre-positioned at a proper position in the flange through the quick-mounting flange positioning pin. And when the locking ring is rotated, the locking mechanism is pressed down due to the thread fit relationship, and forms a close fit relationship with the operation component. Due to the action of the non-return mechanism, the reverse movement of the locking ring is limited, and the operation part is locked and fixed. Thereby allowing the work component and the robot arm to be closely coupled. The quick-mounting flange is simple in structure, and enables installation of operation parts to be more convenient.
The invention has the advantages that: 1. the quick-mounting flange for the orthopedic surgery robot with the non-return mechanism has the function of connecting the mechanical arm and the surgical instrument, wherein the operation part is pre-positioned at a proper position in the flange through a quick-mounting flange positioning pin, the locking ring is rotated to form a close fit relation with the operation part, the circumferential movement of the locking ring is limited, and meanwhile, the operation part is locked and fixed, so that the operation part is tightly connected with the mechanical arm; 2. in order to solve the problem that the surgical instrument is repeatedly disassembled and assembled in the actual use process, if the surgical machine needs to be disassembled, the release ring only needs to be screwed forcefully in the opposite direction, the non-return cylinder is withdrawn from the over-matching state, and the circumferential movement of the locking ring is not limited. The locking ring is moved to a position which is separated from the dismounting contact surface of the operation part, and the operation instrument can be directly taken down to replace other tools.
