Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to a uterine manipulator. Background Art

[0002] During gynecological laparoscopic surgery or focused ultrasound treatment, the uterine manipulator is one of the commonly used instruments. Whether performing related surgeries or using intrauterine perfusion, a traditional uterine manipulator needs to be used. The traditional uterine manipulator is used by inserting the uterine manipulator into the cervical opening of women to fix the uterine manipulator. The traditional uterine manipulator includes a uterine manipulator in the shape of a fixed truncated cone with a central opening. The center of the uterine manipulator in the shape of a fixed truncated cone is fixed on a connecting rod. The shape and size of the uterine manipulator are fixed and cannot be adjusted. Due to the different body structures of each person, usually, the cervical opening of women who have never given birth is very small, while the cervical opening of women who have given birth is larger. However, the uterine volume of women is usually only about 5 ml, so the shape of the uterine manipulator cannot be made into a fixed truncated cone with a larger slope, and the outer diameter of the truncated cone with a gradually changing diameter is stuck at the cervical opening. Traditional uterine manipulators cannot be used when used on patients with a very small cervical os, as forcing them into the cervical os will cause injury to the patient. Traditional uterine manipulators cannot be used when used on patients with a very large cervical os, as the cervical os cannot be relied upon to fix the uterine manipulator. Therefore, a uterine manipulator with a fixed shape and size cannot ensure that it is suitable for all patients. Moreover, the use of traditional uterine manipulators will cause injury and pain to the patient when they are withdrawn from the cervix after use. Summary of the invention

[0003] In view of the technical problems existing in the prior art, the present invention provides a uterine manipulator capable of adjusting the diameter of the uterine lifting part, thereby bringing convenience to treatment.

DETAILED DESCRIPTION

[0014] In order to enable those skilled in the art to better understand, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0015] like Figure 1The uterine manipulator shown includes a uterine manipulator part 1, an outer rod 2, a first connecting rod 3 and a second connecting rod 4, wherein the uterine manipulator part 1 is a truncated cone body with a hollow structure, and the uterine manipulator part 1 includes a flexible baffle 13 and an elastic sheet 12 hinged to the flexible baffle 13, wherein a through hole 11 is opened at the center of the flexible baffle 13, the inner wall of the elastic sheet 12 is made of a rigid material and the outer wall is provided with a silicone layer; the first connecting rod 3, the second connecting rod 4 and the outer rod 2 are all hollow structures, wherein one end of the first connecting rod 3 is fixed at the center of the top inside the uterine manipulator part 1, the second connecting rod 4 is slidably connected to the first connecting rod 3, and the top of the second connecting rod 4 passes through the first connecting rod 3 and the through hole 11 in turn, and is connected to the first The fastening bolt 31 at the end of the connecting rod 3 is fixed to the first connecting rod 3; the outer rod 2 is connected to the outer thread of the first connecting rod 3 through an internal thread, wherein a circular supporting block 21 is provided on the top of the outer rod 2, and an independent connecting sleeve 22 is sleeved on the top of the supporting block 21, and a support rod 23 is fixedly provided on the outer wall of the independent connecting sleeve 22 at even intervals, and a roller 24 is provided at the support rod 23 to be slidably connected to the inner side of the elastic sheet 12; a smooth flexible head 41 is provided on the top of the second connecting rod 4, and a liquid spraying hole 42 is opened on the flexible head 41, and an air bag 43 is connected to the bottom of the second connecting rod 4, and a liquid injection port 44 is provided on one side above the air bag 43. A sealing plug is provided at the liquid injection port 44. The diameter of the through hole 11 is smaller than the inner diameter of the first connecting rod 3. A compression spring 25 is sleeved on the top of the first connecting rod 3, and the two ends of the compression spring 25 are respectively fixedly connected to the inner wall of the flexible baffle 13 and the independent connecting sleeve 22. There are at least four support rods 23 and four rollers 24. The bottom of the second connecting rod 4 is provided with anti-slip grooves. The angle between the support rod 23 and the independent connecting sleeve 22 is 30° to 60°.

[0016] In the present invention, the lifting part 1 is a truncated cone with a small upper part and a large lower part. Before use, first rotate the outer rod 2. Driven by the outer rod 2, the supporting block 21 is lowered to the lowest point in the lifting part 1, so that the diameter of the lifting part 1 is in the smallest state. Then loosen the fastening bolt 31, and adjust the relative position of the second connecting rod 4 and the first connecting rod 3 to adjust the distance extended by the flexible head 41 at the front end of the lifting part 1. After adjustment, screw the fastening bolt 31 into the screw hole at the end of the first connecting rod, and fix the relative position of the first connecting rod 3 and the second connecting rod 4 by the fastening bolt 31 to prevent the second connecting rod 4 from sliding. Then the medical staff holds the second connecting rod 4 to extend the uterine manipulator into the uterus. At this time, the position of the supporting block 21 is adjusted by rotating the outer rod 2. While the supporting block 21 rotates upward, the supporting block 21 drives the independent connecting sleeve 22 mounted on the supporting block 21 to move. The pulley 24 fixed by the support rod 23 on the independent connecting sleeve 22 moves toward the top surface of the uterine manipulator 1 under the push of the supporting block 21. In the process of the supporting block 21 moving upward, the diameter of the uterine manipulator 1 becomes larger until it is adjusted to a size suitable for the patient's cervical opening, thereby fixing the uterine manipulator with the patient's cervix. In addition, drugs need to be injected during the operation. The drugs can be injected from the drug injection port 44, and the drug injection port 44 is sealed by a sealing plug. The air bag 43 is squeezed to squeeze the drug out of the spray hole 42 to inject the drug into the designated part. When the uterine manipulator needs to be taken out after use, the outer rod 2 is rotated in the opposite direction, and the supporting block 21 no longer applies pressure to the independent connecting sleeve 22. At this time, the other end of the independent connecting sleeve 22 is subjected to the elastic force of the compression spring 25 and is restored to its original position with the help of the force of the compression spring 25, thereby reducing the diameter of the uterine manipulator 1 and allowing the uterine manipulator to be taken out smoothly, thus avoiding secondary injury to the patient.
