[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example:

[0020] The present embodiment provides a quick-release and quick-install structure for the front-end instrument of the navigation robot for joint replacement surgery, including: a mechanical arm 1, a flange 2, a gripper fixing plate 3, a butterfly-shaped captive screw 4, and a front-end gripper 5. Among them, the mechanical arm 1 is the basic support part of the entire structure, and is fastened to the flange 2 through a stable connection method. Matching internal threads are provided on the flange 2 and the gripper fixing plate 3, and the two are threadedly connected by butterfly-shaped captive screws 4. There are three butterfly-shaped captive screws 4, and the design of the butterfly-shaped captive screws 4 is convenient for manual operation. It only takes a simple rotation to complete the tightening or loosening, which greatly speeds up the assembly and disassembly speed of the gripper fixing plate and the mechanical arm, and saves the surgical preparation time. A slot 6 is designed in the center of the gripper fixing plate 3, and the front-end gripper 5 can be tightly combined with the gripper fixing plate 3 through the slot 6 to achieve a firm connection. The front-end gripper 5 adopts a replaceable design. According to different surgical requirements, medical staff can choose front-end grippers of different types and functions for quick replacement, which enhances the flexibility and scope of application of the system. The robotic arm 1 has six joints, which work together to enable the front end gripper 5 to move flexibly and achieve precise positioning to meet the needs of various complex surgical scenarios.

[0021] The butterfly captive screw 4 includes a butterfly screw head 7, a threaded section 8 placed below the screw head, and a cylindrical section 9 between the screw head and the threaded section, the top surface of the cylindrical section 9 is fixedly connected to the butterfly screw head 7, and the bottom surface of the cylindrical section 9 is fixedly connected to the threaded section 8; the diameter of the cylindrical section 9 is smaller than the diameter of the threaded section 8.

[0022] In order to enhance the positioning freedom of the gripper in space, the present embodiment further adds a rotating mechanism on the central axis of the robotic arm 1. By manipulating the rotating mechanism, the angle of the front gripper 5 can be adjusted conveniently and quickly to ensure that it is always in the most suitable position for surgical operation.
