A plurality of brackets 2 are fixedly connected to the bottom of the sliding ring 1 . A foot seat 3 is fixedly connected to the bottom of the bracket 2 . The foot seat 3 is made of rubber material. The sliding sleeve 41 is arranged in a semicircular shape and matches the sliding ring 1 .

The device in this scheme is mainly used to assist doctors in performing urological surgery. Since there are many tissues and ureters in the human urinary system, some tissues need to be lifted during the operation so that the doctor can operate on the lesion.

The above-mentioned hook assembly 6 is used to hook up tissue. The hook assembly 6 is installed on the telescopic assembly 5. The telescopic assembly 5 can drive the hook assembly 6 to telescopically move through the cooperation of the knob 54 and the threaded rod 52, which is convenient for adjustment. The telescopic assembly 5 is rotatably connected to the sliding assembly 4, so as to achieve the purpose of adjusting the angle of the hook assembly 6. The sliding sleeve 41 is semicircular, and three fixing blocks 42 are fixed on the inner side of the sliding sleeve 41, two of which are located at the edge of the sliding sleeve 41, which play a limiting role, so that the sliding sleeve 41 can be fixed on the outer end of the sliding ring 1, and at the same time, the outer end of the sliding ring 1 is provided with three annular grooves matching the fixing blocks 42, so that the sliding sleeve 41 can slide outside it, which is convenient for doctors to adjust the position when using it.

The sliding ring 1 is supported by four brackets 2, and a foot 3 made of rubber is provided at the bottom of the bracket 2, so that the sliding ring 1 can be placed on the operating table without manual holding, thereby reducing hand fatigue and burden, improving the stability and accuracy of the operation, and providing a better field of view and visibility, so as to observe the operating area more clearly.

Please refer to Figures 1 to 4. The telescopic assembly 5 includes a mounting rod 51 and a knob 54. The knob 54 is fixedly connected to a limit block 55 near the mounting rod 51. The limit block 55 is arranged in a T shape. A limit groove matching the limit block 55 is formed at one end of the mounting rod 51 near the knob 54. The limit block 55 is slidably connected to the limit groove.

The telescopic assembly 5 also includes a threaded rod 52, and a thread matching the threaded rod 52 is arranged on the inner side of the knob 54. The threaded rod 52 passes through the knob 54 and extends to the inside of the mounting rod 51. The threaded rod 52 is threadedly connected to the knob 54. The end of the threaded rod 52 away from the hook assembly 6 is fixedly connected to a slider 53. A sliding groove matching the slider 53 is opened inside the mounting rod 51, and the slider 53 is slidably connected to the sliding groove.

When it is necessary to control the extension and retraction of the hook assembly 6, it is necessary to turn the knob 54. Since the knob 54 is threadedly connected to the threaded rod 52, and the knob 54 is restricted on the mounting rod 51 by the limit block 55, the knob 54 can be rotated at the end of the mounting rod 51 without displacement. At this time, the threaded rod 52 will move and retract inside the mounting rod 51. At the same time, a slider 53 is fixed to one end of the threaded rod 52. The slider 53 plays a limiting role. When the knob 54 is turned, the threaded rod 52 will not rotate with it. By turning the knob 54, the position of the hook assembly 6 can be adjusted, which is convenient to use.

Please refer to FIG. 1 and FIG. 3 , the hook assembly 6 includes a pick plate 61 and a pair of hooks 62 . The pair of hooks 62 are respectively fixedly mounted on both sides of the pick plate 61 , and the pair of hooks 62 are symmetrically distributed.

The lifting piece 61 and the retractor 62 in this solution can cooperate to lift the human body. The lifting piece 61 is in the shape of a "human" character, and a pair of retractor hooks 62 are arranged at the end of the lifting piece 61. The retractor hooks 62 are arranged to be inclined outward to reduce damage to tissues when hooking.

The main mounting shaft 71 and the secondary mounting shaft 72 in this solution are mainly used to adjust the rotational damping of the mounting rod 51. The main mounting shaft 71 passes through the mounting rod 51 and the sliding sleeve 41. By adjusting the tightness of the threaded connection between the secondary mounting shaft 72 and the main mounting shaft 71, the rotational damping between the mounting rod 51 and the sliding sleeve 41 can be controlled, thereby improving the convenience of use.

Working principle: When using the device in this scheme, first, the sliding ring 1 needs to be installed on the operating table through the bracket 2 and the foot seat 3. The sliding sleeve 41 is semicircular, and three fixing blocks 42 are fixed on the inner side of the sliding sleeve 41, two of which are located at the edge of the sliding sleeve 41, which play a role of limiting. The outer end of the sliding ring 1 is provided with three annular grooves matching the fixing blocks 42, so that the sliding sleeve 41 can slide outside it. When it is necessary to control the retractor assembly 6 to retract, it is necessary to rotate the knob 54. Since the knob 54 is threadedly connected to the threaded rod 52, the threaded rod 52 will move and retract in the mounting rod 51. At the same time, a slider 53 is fixed to one end of the threaded rod 52. The slider 53 plays a role of limiting. When the knob 54 is turned, the threaded rod 52 will not rotate with it. The picking piece 61 and the retractor 62 can cooperate to pick up the human body. The picking piece 61 is in the shape of a "human", and a pair of retractors 62 are arranged at the end of the picking piece 61. The retractors 62 are arranged to be inclined outward to reduce damage to the tissue when hooking it up.
