Description

Technical Field

[0001] The utility model relates to the technical field of uterine manipulators, in particular to a uterine manipulator for fixing the uterus. Background Art

[0002] The uterine manipulator is used for total or subtotal hysterectomy. It mainly includes a central guide rod, a cervical fixator, and a vault cup. The characteristics of the uterine fixator are that the front part is provided with a cervical support, and the front end is a threaded cone. The cervical fixator has a central channel axially opened inside, and the central guide rod passes through it. The vault cup is wrapped around the outer periphery of the cervical fixator, and the inner diameter of the front part is greater than or equal to the diameter of the cervical support to form a cup body, and the rear part is narrowed to form a handle. The end of the handle is provided with a screw that can fix the vault cup at a specific position of the cervical fixator. The three different parts can be organically combined together, so that the problems encountered in laparoscopic total hysterectomy, such as gas leakage after vaginal incision, difficulty in swinging the uterus, and blurred display of the boundary between the cervix and the vaginal wall, are solved, which is particularly conducive to the complete removal of the cervix.

[0003] Existing Chinese patent publication numbers (CN215584333U, CN215306545U) respectively propose a uterine fixation device for gynecological laparoscopic surgery and a uterine fixation device for gynecological laparoscopic surgery. The structural design of the device can adjust and lock the angle of the front end of the device inserted into the uterus, but the structural design is complex and the adjustment angle is limited. Utility Model Content

[0007] Preferably, anti-slip grooves are cold-rolled on the outside of the knob and the tail of the threaded fastener to facilitate applying a torsional force during rotation.

[0008] Preferably, angle display scales are provided at intervals at the tail end of the insertion rod, and a reference line is fixed on the knob to display the reference angle, so that medical staff can adjust the rotation angle of the uterine lifting rod with reference.

[0010] Preferably, the silicone sheath is in a conical sheath structure, which is inserted into the front end of the uterine lifting rod so that it will not move backward after being inserted into the body.

[0011] Preferably, a non-slip rubber sleeve with a concave-convex structure is fixedly mounted on the outside of the handle.

[0012] The advantages and positive effects of the utility model are:

[0013] 1. Simple structure, easy to manufacture and assemble.

[0014] 2. Any angle adjustment can be achieved by turning the knob, and the adjustment range is larger than that of the prior art.

[0015] 3. The silicone sheath effectively improves the flatness and smoothness of the device, making it easier to insert into the body. BRIEF DESCRIPTION OF THE DRAWINGS
