Description

Technical Field

[0001] The utility model relates to the technical field of cervical pretreatment, in particular to a novel cervical dilator. Background Art

[0002] Uterine cavity operation is a commonly used diagnosis and treatment method in obstetrics and gynecology. Given the poor extensibility of cervical tissue, cervical pretreatment before uterine cavity operation is particularly important. Mechanical methods can be used to promote cervical ripening, ensure smooth uterine cavity operation, and reduce surgical complications. In order to improve the success rate and safety of uterine cavity operation, it is necessary to design a reasonable and easy-to-operate cervical dilation device. For women of childbearing age, the cervix needs to be dilated to 9.5-10.0 mm before hysteroscopy, curettage, placement or removal of intrauterine contraceptive devices. Common complications are mainly related to cervical dilation difficulties, including cervical laceration, formation of false passages, and uterine perforation. Therefore, cervical preparation is required before surgery to facilitate surgery and reduce surgical complications. Due to ovarian failure, low estrogen levels, obvious atrophy of the cervix and uterus, hard cervix, and cervical canal stenosis in postmenopausal women, adequate cervical pretreatment should be performed before uterine cavity operation (such as hysteroscopy and surgery and IUD removal) to facilitate surgical operation and reduce surgical risks.

[0003] The cervical dilator commonly used in clinical practice has an unlimited position function and cannot control the depth of the cervical dilator entering the uterine cavity. It is easy to cause uterine perforation and form a false passage during operation, which increases the trauma and burden of the patient, makes the entire operation more time-consuming and energy-consuming, and affects the surgeon's concentration and the quality of the operation.

DETAILED DESCRIPTION

[0030] Please refer to the attached Figure 1 - Figure 5 , shows a new type of cervical dilation rod provided in an embodiment of the present application, including: a rod body 1 and a sleeve body 2.

[0031] Among them, the first end of the rod body 1 is used for cervical pretreatment, and the first end of the rod body 1 is set to a round blunt head 102, which can prevent the end of the rod body 1 from causing damage to the cervix. The sleeve 2 is sleeved on the second end of the rod body 1, so that the operator can operate the rod body 1 through the sleeve 2. The side of the sleeve 2 is fixedly connected with a limiting part 203. The distance between the end of the standard length of the rod body 1 used for cervical pretreatment and the limiting part 203 can be pre-set, so as to avoid uterine perforation and formation of false passages during operation, increase the trauma and burden of the patient, make the entire operation process more time-consuming and energy-consuming, and affect the surgeon's concentration and operation quality.

[0032] For example, the length of the rod 1 is designed to be 10 mm, and 14 groups of rods are designed according to the diameter of the rod 1. The 14 diameters are 4.5 mm, 5 mm, 5.5 mm, 6 mm, 6.5 mm, 7 mm, 7.5 mm, 8 mm, 8.5 mm, 9 mm, 9.5 mm, 10 mm, 10.5 mm, and 11 mm respectively.

[0033] A first circular hole 105 and a second circular hole 106 are provided on the side of the rod body 1 located inside the sleeve body 2. The first circular hole 105 and the second circular hole 106 are distributed along the length direction of the rod body 1. A fixing protrusion is provided on the side of the sleeve body 2. The fixing protrusion corresponds to the first circular hole 105 and the second circular hole 106. When the fixing protrusion is inserted into the first circular hole 105 and / or the second circular hole 106, the rod body 1 is fixedly connected to the sleeve body 2.

[0034] In one embodiment, the fixing protrusions include: a first fixing protrusion 204 and a second fixing protrusion 205 , and the first fixing protrusion 204 and the second fixing protrusion 205 are distributed along the length direction of the sleeve body 2 .

[0035] In the first method, when the first fixing protrusion 204 is aligned with the first circular hole 105 and the second fixing protrusion 205 is aligned with the second circular hole 106 , the rod body 1 and the sleeve body 2 can be fixedly connected.

[0036] Method 2: When the second fixing protrusion 205 is aligned with the second circular hole 106 , the rod body 1 and the sleeve body 2 can also be directly fixedly connected.

[0037] In the above two methods, the rod body 1 and the sleeve body 2 can be fixedly connected. The difference is that the relative positions of the rod body 1 and the sleeve body 2 are different (that is, the distance between the end of the rod body 1 used for cervical pretreatment and the limiting part 203 is different), which is adjusted according to actual needs.

[0038] In one embodiment, the first fixing protrusion 204 includes: a flexible sleeve 2041 recessed inward from the outside of the sleeve body 2, a hard block 2042 is fixedly connected to the inner bottom of the flexible sleeve 2041, and an ear buckle 2043 is fixedly connected to the side of the hard block 2042.

[0039] The flexible sleeve 2041 is easy to deform and will not affect the sliding of the rod body 1 on the inside of the sleeve 2. After aligning the flexible sleeve 2041 with the first circular hole 105 or the second circular hole 106, the hard block 2042 is squeezed downward and stuck on the inside of the first circular hole 105 or the second circular hole 106 to fix the rod body 1 and the sleeve 2 together; the hard block 2042 is lifted upward using the ear buckle 2043 to release the rod body 1 from the sleeve 2.

[0040] Specifically, the rod body 1 includes: a cylindrical main body 101, one end of the cylindrical main body 101 is set as a blunt head 102, the other end of the cylindrical main body 101 is fixedly connected to a handle 104, the handle 104 is a rectangular parallelepiped, and the first circular hole 105 and the second circular hole 106 are both opened on the side of the handle 104.

[0041] In one embodiment, a scale line 103 is disposed on the side of the cylindrical body 101 to indicate the length of the cylindrical body 101 .

[0042] Specifically, the sleeve body 2 includes: a cylindrical sleeve portion 201 , a first end of the cylindrical sleeve portion 201 is fixedly connected to the outer side of the limiting portion 203 , a second end of the cylindrical sleeve portion 201 is fixedly connected to the square sleeve portion 202 , and a fixing protrusion is arranged on the side of the square sleeve portion 202 .
