Description

Technical Field

[0001] The utility model belongs to the technical field of medical instruments, and in particular relates to a probe uterine dilator. Background Art

[0002] With the popularization of women's health screening, more and more endometrial lesions are now discovered early. According to statistics, the rate of hysteroscopy and uterine cavity exploration in my country ranks first among obstetrics and gynecology surgeries. Therefore, it is particularly important to ensure that the traditional exploration of the uterine cavity position, depth and dilation of the cervical os meet the requirements of uterine cavity surgery under the premise of safety. Excellent and practical surgical instruments are the guarantee of safe and beautiful completion of the operation. The completion of clamping, shearing, suturing and ligation is an important link to ensure the success of the operation. The completion of these basic operating skills is inseparable from the assistance of surgical instruments. Traditional uterine cavity exploration surgery requires entering the uterine cavity through the internal cervical os. For patients with cervical adhesions, short cervical length, and menopausal cervical atrophy, the uterine cavity probe is used, and then the cervix is ​​gradually expanded by the dilator. The operation is complicated and time-consuming, and it is easy to cause cervical tearing and damage. The incidence of complications such as postoperative infection and bleeding is high. Therefore, if the process of dilating the cervix can be simplified and repeated exploration of the uterine cavity can be reduced, the above problems can be avoided to a great extent. Utility Model Content

[0003] The utility model aims at solving the above problems and provides a novel probe dilator for uterine cavity inspection which is easy to use and can avoid complications such as postoperative cervical laceration.

[0004] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical scheme, which includes an outer sleeve, characterized in that: an intermediate tube is arranged in the outer sleeve, a receiving groove is arranged on the outer surface of the intermediate tube, and a plurality of guide grooves connected with the intermediate tube are arranged in the receiving groove; a plurality of elastic uterine expansion bars are arranged in the receiving groove, the front end of the uterine expansion bars is fixedly connected to the front end of the receiving groove, and the rear ends of the plurality of uterine expansion bars are connected to a pressure ring arranged in the receiving groove; a plurality of connecting blocks corresponding to the guide grooves are arranged in the pressure ring, and the connecting blocks pass through the guide grooves and are connected with the inner sleeve in the intermediate tube by threads; a probe is arranged in the inner sleeve.

[0005] As a preferred solution of the utility model, the probe is an elastic probe with a bending portion at the front end. The elasticity of the probe makes the probe straight when in the inner sleeve. When the probe extends from the inner sleeve, the bending portion bends at an angle under the action of elasticity.

[0006] Furthermore, the front end of the probe is an arc-shaped structure.

[0007] Furthermore, the rear end of the probe extends out of the inner sleeve, the middle tube and the outer sleeve, and is provided with a rotating handle.

[0008] As another preferred solution of the utility model, an operating handle is provided at the rear end of the intermediate tube, and the inner sleeve passes through the operating handle and is connected to an adjusting handle.

[0009] As a third preferred solution of the present utility model, a movable handle is provided at the rear end of the outer sleeve.

[0010] The beneficial effects of the utility model are as follows: first, the probe and the uterine dilator in the traditional sense are two independent medical devices. The probe has a scale for detecting the anterior or posterior position of the uterus and the depth of the uterine cavity. The size of the uterine dilator ranges from 5 to 10 mm, and the size of the uterine dilator is from small to large until the required size when dilating the cervix. When performing uterine cavity exploration, the patient needs to be in a specific position, first use the probe to explore the position and depth of the uterine cavity, and then dilate the cervix. In order to achieve the purpose of accommodating the operation instrument to enter the cervical opening, this process requires repeated replacement of different types of uterine dilator instruments, and repeated operation in and out of the uterine cavity. The process is cumbersome and easy to cause cervical injury. The utility model integrates the probe and the uterine dilator into an integrated structure. When operating on women who need to perform uterine cavity exploration and surgery, the probe is first inserted into the uterine cavity to clarify the depth and front and rear position of the uterine cavity, and then the diameter of the front operating rod is controlled by rotating the end handle of the instrument to gradually dilate the cervix to meet the surgical requirements. This invention can greatly avoid the risks of bleeding, infection, etc. caused by repeated operation in and out of the uterine cavity, which not only improves the efficiency of the operation, but also simplifies the operation process, and has a very high clinical application and promotion value.

DETAILED DESCRIPTION

[0016] The utility model includes an outer sleeve 4, which is characterized in that: an intermediate tube 3 is arranged in the outer sleeve 4, a receiving groove 14 is arranged on the outer surface of the intermediate tube 3, and a plurality of guide grooves 5 connected with the intermediate tube 3 are arranged in the receiving groove 14; a plurality of elastic uterine expansion bars 6 are arranged in the receiving groove 14, the front end of the uterine expansion bar 6 is fixedly connected with the front end of the receiving groove 14, and the rear ends of the plurality of uterine expansion bars 6 are connected with a pressure ring 7 arranged in the receiving groove 14; a plurality of connecting blocks 8 corresponding to the guide grooves 5 are arranged in the pressure ring 7, and the connecting blocks 8 pass through the guide grooves 5 and are connected with the inner sleeve 2 in the intermediate tube 3 by threads; a probe 1 is arranged in the inner sleeve 2.

[0017] As a preferred embodiment of the present invention, the probe 1 is an elastic probe 1, and a bending portion 13 is provided at the front end of the probe 1. The elasticity of the probe 1 makes the probe 1 straight when in the inner sleeve 2. When the probe 1 extends out of the inner sleeve 2, the bending portion 13 bends at an angle under the action of the elasticity.

[0018] Furthermore, the front end of the probe 1 is an arc-shaped structure.

[0019] Furthermore, the rear end of the probe 1 extends out of the inner sleeve 2, the middle tube 3 and the outer sleeve 4, and is provided with a rotating handle 12.

[0020] As another preferred solution of the present invention, an operating handle 10 is provided at the rear end of the intermediate tube 3 , and the inner sleeve 2 passes through the operating handle 10 and is connected to an adjusting handle 11 .
