Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to a uterine manipulator for gynecology. Background Art

[0002] Since the uterus and the cervix are integrated and connected to the vagina, it is a multiple-occurrence part of gynecological diseases. During the laparoscopic surgical treatment, special medical devices are required. Generally, a uterine manipulator is used to move the human uterus to the required surgical position, help the surgical operator (doctor) define the vaginal and uterine tissues, fully expose the surgical field, and be used as a backing during resection, etc.

[0003] An existing uterine manipulator, such as a uterine manipulator with the patent number 201020209565.8, discloses including a guiding rod, a handle, a sliding rod, a locator and a flushing valve. Among them, the handle and the sliding rod are fixed; the locator is sleeved on the guiding rod and fixed with a fixing screw, the sliding rod is sleeved on the guiding rod and fixed with an adjusting screw, and the flushing valve is sleeved on the guiding rod and fixed with a connecting nut; flushing holes are opened on the guiding rod. However, its cervical clamp positioning card is arranged on the handle. Generally, two cervical clamps are required to cooperate with the surgical operation together. The position space of the cervical clamp positioning card is insufficient, and the handle is not easy to operate. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a uterine manipulator, which has the advantages of simple structure and convenient operation.

[0005] The technical solution of the utility model: a uterine manipulator, including a hollow guiding rod, a cervical support, a cervical clamp positioning card, a handle and a flushing valve which are sequentially sleeved along the head-to-tail direction of the hollow guiding rod. The cervical clamp positioning card includes a sliding block, and two positioning hooks with a V-shaped position are arranged on the sliding block. A locking nut is arranged on the opposite side of the positioning hook.

[0006] In the foregoing uterine manipulator, a sliding rod is sleeved on the hollow guiding rod, the sliding rod is fixedly connected with the handle, and the locking nut of the cervical clamp positioning card controls and locks the position of the sliding rod on the hollow guiding rod; in order to facilitate the reset of the sliding rod, a spring is sleeved between the hollow guiding rod and the sliding rod.

[0007] In the foregoing uterine manipulator, the handle is two waist-shaped cylindrical grips that are symmetric up and down, which is convenient for doctors to hold and operate stably.

[0008] In the foregoing uterine manipulator, the head of the hollow guiding rod is provided with a warping part, the included angle between the warping part and the horizontal plane is 25° - 35°, and flushing holes are provided at the head of the warping part.

[0009] Compared with the prior art, the utility model is provided with a separate positioning card for the uterine cervix forceps. There are two positioning hooks with a V-shaped position on the positioning card for the uterine cervix forceps, which is convenient for positioning and clamping the uterine cervix forceps. The uterine cervix forceps has corresponding operating positions, which can better cooperate with the surgical operation. The positioning card for the uterine cervix forceps can move relatively to meet the usage requirements of various uterine surgeries;

[0010] Furthermore, in the utility model, the handle is composed of two kidney-shaped cylindrical grips that are symmetrically arranged up and down, which is convenient for doctors to hold more comfortably and stably, reducing the fatigue of doctors during the operation;

[0011] Furthermore, the utility model is provided with a warping part, which fits the uterine wall better and enables the uterine cervix support to position and hold the uterus well;

[0012] Furthermore, the utility model is provided with a flushing valve, which is convenient for flushing the surgical area during the operation and does not require frequent replacement of surgical instruments.

[0013] In summary, the utility model has the advantages of simple structure and convenient operation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following is a further specific description of the technical solution of the utility model through examples and in combination with the drawings, but it is not used as the basis for limiting the utility model.

[0018] Example 1. A uterine lifting device, as Figure 1-2 shown, includes a hollow guiding rod 1, a uterine cervix support 2, a positioning card 3 for uterine cervix forceps, a handle 4, and a flushing valve 5 that are sequentially sleeved along the head-to-tail direction of the hollow guiding rod 1. The positioning card 3 for uterine cervix forceps includes a sliding block 31. There are two positioning hooks 32 with a V-shaped position on the sliding block 31, and a locking nut 33 is provided on the opposite side of the positioning hook 32.

[0019] A sliding rod 6 is sleeved on the hollow guiding rod 1, the sliding rod 6 is fixedly connected with the handle 4, and the locking nut 33 of the positioning card 3 for uterine cervix forceps controls and locks the position of the sliding rod 6 on the hollow guiding rod 1.

[0020] A spring is sleeved between the hollow guiding rod 1 and the sliding rod 6.

[0021] The described handle 4 is two waist-shaped cylindrical grips that are symmetrical up and down.

[0022] The head of the hollow guiding rod 1 is provided with a warped part. The angle θ between the warped part and the horizontal plane is 30°. It fits the uterine wall better and can enable the uterine support to locate and hold the uterus better.

[0023] A plurality of flushing holes 11 are rotatably provided at the head of the warped part, and the flushing range is larger.

[0024] During use, loosen the fixing screw to make the uterine support 2 slide on the hollow guiding rod 1. Adjust the position and lock it. The hollow guiding rod 1 enters the human uterus, making the uterine support 2 just top on the cervix. The hollow guiding rod 1 can control the depth of the uterus, so that the uterus will not move randomly during uterine elevation. Under the vision of the laparoscope, the uterus will be clearer in the human body and will not move randomly.

[0025] Loosen the lock nut 33 to make the slide rod 6 slide on the hollow guiding rod 1. The length of the slide rod 6 can be adjusted at any time according to the needs of the operation. At the same time, adjust and determine the position of the cervical clamp positioning card 3 to make the operation proceed smoothly.

[0026] The flushing valve 5 is connected to a flushing and suction device, and surgical flushing can be carried out during operations on women's vaginal and uterine diseases, which is very convenient.
