Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, and particularly relates to a cervical clamp. Background Art
[0002] After women menopause, due to the change of hormone levels, the cervix will show obvious physiological atrophy, and the degree of atrophy varies from person to person. And hysteroscopy examination or surgical operation of tissue sampling is often required for intrauterine space-occupying lesions after menopause. At this time, the atrophic cervical conditions increase the difficulty of hysteroscopy operation for postmenopausal women. Even if vaginal suppositories can be used clinically for preoperative cervical preparation to try to soften the cervix, there are still some patients with severe cervical atrophy, the contour of the external cervical os disappears or even the external cervical os is completely closed, which makes it very difficult to clamp and fix the cervix with a cervical clamp, and further hysteroscopy operation cannot be carried out. In addition, due to the atrophy of the external cervical os, it is very difficult to find the external cervical os with a cervical probe, and violent operation is extremely likely to cause failure of cavity exploration because it cannot enter the uterine cavity through a false tract, and even cause damage to surrounding organs, such as uterine perforation, bladder perforation, and even rectal injury, etc. The consequences are unimaginable, causing serious adverse consequences to the health of patients, increasing the economic burden of patients and causing adverse social impacts. Therefore, for the key steps to be solved in hysteroscopy operation for postmenopausal women, it is to use reasonable instruments to clamp and fix the cervix and dilate the cervix.
[0003] As Figure 1 shown, the existing cervical clamp, commonly known as cervical forceps 1, is an "X-shaped" forceps made of metal, including two metal forceps body rods, two ring handles at the tail end, a middle fixing screw, and a clamping structure formed by the rat teeth of the two forceps bodies at the head end, and the forceps body at the head end of the cervical forceps 1 is slightly arc-shaped.
[0004] Due to the existing head end design of the existing cervical clamp, when clamping and fixing the cervix, because it can only clamp one part of the circular cervix, the natural direction of the cervix and the uterine cavity line after being pulled is artificially changed, and then the cervical probe operation is extremely likely to cause difficulty in cavity exploration or even perforation. In addition, for the severely atrophic cervix, the cervical flattening makes the cervical appearance contour disappear. The plane formed after the clamping and closing of the head end of the existing cervical forceps 1 is parallel to the transverse section of the external cervical os, and the cervix cannot be clamped. Even if the adjacent vaginal tissue is barely clamped, it may cause damage and bleeding of the vaginal wall, and it is not firm enough to carry out the next operation. The traction of surrounding tissues affects the natural direction of the cervix and the uterine cavity line, further increasing the difficulty and risk of the surgical operation.

[0032] The cervical clamp device provided by the present utility model greatly improves the success rate of the fixation operation of the atrophic cervix of postmenopausal women, improves the safety and convenience of the operation, reduces the injury of the vaginal wall around the cervix, and improves the surgical safety. The advantage of in-situ cavity entry makes the cervical cavity exploration operation safer and easier to enter the cavity, which is beneficial to the safety of the patient during the surgical treatment process and reduces the complications of hysteroscopic surgery.
[0033] In a preferred embodiment, the rat tooth part 33 is arranged towards the second side clamp head 42, and a corresponding fixing surface is arranged on one side of the second side clamp head 42 close to the rat tooth part 33.
[0034] Specifically, on the basis of the existing technology, the present utility model abandons the homogeneous design of the head end clamp bite, and changes to a structure of a biting clamp with a rat tooth part 33 plus a clamp body provided with a hollow tube 43. By inserting the thin-type probe 5 into the hollow tube 43, when performing the operation of severe cervical atrophy, the clamp body containing the hollow tube 43 is easier to insert into the external orifice of the cervix and bite with the rat tooth part 33 to fix the cervix. Under the advantage of in-situ cavity entry, the original direction of the cervical canal and uterine cavity can be not changed. Further, the thin-type probe 5 is inserted into the cervical canal through the hollow tube 43 to more safely and effectively clarify the direction of the cervical canal, in order to reduce the surgical operation risk, avoid surgical perforation, make the operation more convenient and easier to perform, and reduce surgical complications.
[0035] In a preferred embodiment, the cervical clamp 2 includes a first clamp body 3 and a second clamp body 4. The first clamp body 3 and the second clamp body 4 are connected by a fixing member 21 and rotatably connected with the fixing member 21 as a fixed point.

The connecting portion 44 and the connection between the first clamp handle portion 34 and the first clamp jaw portion 31 are connected by the fixing member 21.
[0038] Specifically, the present utility model changes the "X-shaped" structure of the cervical clamp in the prior art. The second clamp body 4 is connected between the second clamp handle portion 45 and the second clamp jaw portion 41 through the connecting portion 44, which can change the biting mode between the ratchet teeth portion 33 and the second side clamp head 42, so that it is not necessary for the first clamp body 3 and the second clamp body 4 to be closely attached for biting, maintaining the advantage of the second clamp body 4 entering the cavity in place, and facilitating the probe 5 to explore the direction of the cervical canal.
[0039] In a preferred embodiment, the first side clamp head 32 is arranged on the front side of the first clamp jaw portion 31, the second side clamp head 42 is arranged on the front side of the second clamp jaw portion 41, and the cross-sectional dimension of the second side clamp head 42 is larger than the cross-sectional dimension of the remaining part of the second clamp jaw portion 41.
[0040] In a preferred embodiment, the probe 5 outlet end of the hollow tube 43 is arranged at the top of the second side clamp head 42, and the probe 5 inlet end of the hollow tube 43 is arranged at the bottom of the second side clamp head 42 and on the side of the second clamp jaw portion 41 away from the first clamp jaw portion 31 below the second side clamp head 42.
[0041] Specifically, the cross-sectional dimension of the second side clamp head 42 is larger than the cross-sectional dimension of the remaining part of the second clamp jaw portion 41. The probe 5 inlet end of the hollow tube 43 is arranged at the bottom of the second side clamp head 42 and on the side of the second clamp jaw portion 41 away from the first clamp jaw portion 31 below the second side clamp head 42, which is more conducive to the probe 5 entering the hollow tube 43 and improving the convenience of operation; at the same time, the setting direction of the hollow tube 43 maintains the advantage of the second clamp body 4 entering the cavity in place, facilitating the probe 5 to explore the direction of the cervical canal.
[0042] In a preferred embodiment, the bottom surface of the second side clamp head 42 has a set slope, and the inclination direction is gradually inclined upward along the direction away from the first clamp jaw portion 31.
[0043] Specifically, the bottom surface of the second side clamp head 42 is gradually inclined upward, such that the probe 5 inlet end of the hollow tube 43 faces a direction convenient for operation, which is more conducive to the probe 5 entering the hollow tube 43 and improves the convenience of operation.
