Abstract
Description
Technical Field
[0001] The present invention relates to the technical field related to laparoscopic cervical cancer surgery equipment, and in particular to a vaginal cerclage and removal device used in laparoscopic cervical cancer surgery. Background Art
[0002] Laparoscopy has the advantages of less trauma, magnified surgical field, clear anatomy, and fewer postoperative complications, and is widely used in cervical cancer surgery. According to relevant literature reports in recent years, laparoscopic surgery for early cervical cancer has a lower five-year tumor-free survival rate, higher recurrence rate, and higher mortality rate than open surgery. During laparoscopic cervical cancer surgery, the squeezing of the cancer foci by the uterine manipulator and the exposure of the cancer foci when the vagina is severed are one of the main causes of tumor cell dissemination and implantation metastasis. Strict adherence to the tumor-free principle during tumor surgery is an important guarantee for the patient's prognosis. In open surgery for cervical cancer, right-angle forceps are used to Closing the vaginal stump, cutting it off and taking it out together with the uterus through the abdominal incision can effectively avoid the exposure of cancer foci and the shedding of tumor cells leading to pelvic and abdominal dissemination and implantation. In laparoscopic cervical cancer surgery, the application of the uterine-lift-free technique can reduce the risk of tumor cell vascular metastasis caused by squeezing and friction of tumor tissue. However, in order to avoid the problem of cancer foci exposure when the vagina is severed, it is conventional to use a Malpighian ligature to isolate the tumor tissue by ligating the vagina, then cut the vagina and remove the resected tissue from the vagina. Therefore, there is a special need for a vaginal cerclage and removal device for laparoscopic cervical cancer surgery.
[0003] However, the prior art has the following problems: After entering the abdominal cavity, the conventional ligature ring needs to pass through the back of the vagina, which makes it inconvenient to operate in the abdominal cavity because the ligature ring cannot be bent and shaped; during the cerclage process, the base of the clamp head is close to the vaginal wall, and the cassette must be prevented from rotating to prevent the cassette from failing to tighten, resulting in incomplete vaginal closure. Repeated adjustments are usually required to achieve the ideal cerclage state; when cutting the vagina, the length of vaginal wall resection cannot be indicated, resulting in insufficient or excessive vaginal resection; after cutting the vagina, the ligature ring will detach, exposing the tumor tissue. In summary, although the Malpighian ligature ring can solve the problem of closing the vagina to prevent tumor exposure, there are also problems such as inconvenient operation and slippage of the ligature ring during use. Summary of the invention
[0004] The purpose of the present invention is to provide a vaginal cerclage and removal device for laparoscopic cervical cancer surgery, which can more conveniently ligate the vagina, indicate the length of vaginal resection, and reduce the exposure of tumor tissue caused by the detachment of the ligation ring, so as to solve the problem proposed in the above background technology that the conventional ligation ring needs to pass through the back of the vagina after entering the abdominal cavity, and the ligation ring cannot be bent and shaped, which makes it inconvenient to operate in the abdominal cavity; during the cerclage process, the base of the clamp head is close to the vaginal wall, and at the same time, it is necessary to avoid the rotation of the cassette to prevent the cassette from being unable to be tightened, resulting in incomplete vaginal closure, and usually repeated adjustments are required to achieve an ideal cerclage state; when cutting the vagina, it is impossible to indicate the length of vaginal wall resection, resulting in insufficient vaginal resection or excessive vaginal resection; after cutting the vagina, the ligation ring will detach, resulting in exposure of tumor tissue. In summary, although the Marsh ligation ring can well solve the problem of closing the vagina to prevent tumor exposure, there are also problems such as inconvenient operation and slippage of the ligation ring during use.
[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a vaginal cerclage and removal device for laparoscopic cervical cancer surgery, comprising a cerclage ring and a vaginal cerclage auxiliary rod, the cerclage ring comprising a clamp, a plastic segment and a cassette, the vaginal cerclage auxiliary rod comprising a functional end and an operating rod.
[0006] Preferably, the chuck is made of nylon or polyethylene, and the chuck is flat and smoothly transitions with the cassette.
[0007] Preferably, the shapeable section is made of nylon or polyethylene, and has a built-in metal wire or is wrapped with a metal sleeve, and can be bent and shaped under the action of external force to facilitate the ligation ring to pass through the back of the vagina.
[0008] Preferably, the cassette is made of nylon or polyethylene and has a cylindrical structure and an annular groove, so as to avoid the non-fitting and loose cerclage caused by the rotation of the conventional ligature ring rolling belt.
[0009] Preferably, the vaginal cerclage auxiliary rod is made of nylon or polyethylene, and the vaginal cerclage auxiliary rod indicates the vaginal resection length through the distance between the functional ends A and B points.
[0010] Preferably, the diameter of the functional end point A is greater than the diameter of the functional end point B, and the ligation ring fixes the vagina at the groove of the functional end to prevent the ligation ring from falling off and assist in removing the excised tissue.
[0011] Preferably, the chuck, the shapeable section and the cassette are integrally formed, and the internal components of the chuck are distributed in a ring shape.
[0012] Preferably, the operating rod of the vaginal cerclage auxiliary rod is provided with anti-slip textures, and the functional end and the operating rod are integrally formed.
[0013] Compared with the prior art, the present invention has the following beneficial effects: The vaginal cerclage and removal device used in laparoscopic cervical cancer surgery can facilitate the laparoscopic vaginal cerclage process through a specially designed cerclage ring. The specially designed cerclage ring shows great convenience in the laparoscopic vaginal cerclage process. Its unique structure and material properties enable medical staff to easily and accurately place the cerclage ring in the corresponding part of the vagina within the limited operating space of the laparoscope, and the cerclage action is smoother and more efficient, effectively reducing the operation time and the surgical risks caused by inconvenient operation, and greatly improving the accuracy and stability of the vaginal cerclage procedure.
[0014] The vaginal cerclage and removal device for laparoscopic cervical cancer surgery uses a vaginal cerclage auxiliary rod to accurately indicate the length of vaginal resection, reducing the shedding of the ligation ring after vaginal cutting. The use of the vaginal cerclage auxiliary rod improves the accuracy of the surgery. The vaginal cerclage auxiliary rod can accurately indicate the length of vaginal resection according to the surgical plan, avoiding the problem of inaccurate resection length caused by human judgment error or limited surgical field of view. At the same time, through the support and positioning function of the auxiliary rod, the position of the ligation ring can be effectively maintained stable during the vaginal cutting operation, significantly reducing the possibility of the ligation ring shedding after vaginal cutting, thereby effectively preventing the exposure of tumor tissue, reducing the risk of tumor cell diffusion and implantation in the abdominal cavity, providing a more reliable guarantee for the patient's surgical prognosis, and can more conveniently ligate the vagina, indicate the length of vaginal resection, reduce the exposure of tumor tissue caused by the detachment of the ligation ring, and optimize the quality and effect of laparoscopic cervical cancer surgery as a whole.

Doctors can perform vaginal resection operations accurately based on this. During the operation, the cerclage ring 1 can firmly fix the vagina in the groove of the auxiliary rod functional end 201.
[0023] The diameter of the functional end 201A point is greater than the diameter of the functional end 201B point. The ligation ring 1 fixes the vagina at the groove of the functional end 201 to prevent the ligation ring 1 from falling off and assist in the removal of excised tissue. By setting the functional ends 201A and B points and using the pre-set fixed distance between the functional ends 201A and B points, an intuitive and accurate reference standard for the length of vaginal excision is provided to the doctor, and the doctor can perform the vaginal excision operation accurately based on this. During the operation, the ligation ring 1 can firmly fix the vagina at the groove of the functional end 201 of the auxiliary rod.
[0024] The clamp head 101, the plastic segment 102 and the cassette 103 are integrally formed, and the internal components of the clamp head 101 are distributed in a ring shape. By arranging the clamp head 101, the plastic segment 102 and the cassette 103 to be integrally formed, the process of laparoscopic vaginal cerclage can be facilitated.
[0025] The operating rod 202 of the vaginal cerclage auxiliary rod 2 is provided with anti-slip textures, and the functional end 201 and the operating rod 202 are integrally formed.

[0027] The clamp head 101 is made of nylon or polyethylene, and is flat and smoothly transitions with the cassette 103. By setting up the clamp head 101, the unique design of the clamp head 101 being flat and smoothly transitioning with the cassette 103 allows it to smoothly pass through narrow incisions and limited space in the abdominal cavity during laparoscopic operation, reducing jams and obstructions, and facilitating accurate arrival at the vaginal cerclage site.
[0028] The plastic segment 102 is made of nylon or polyethylene. The plastic segment 102 has a built-in metal wire or a wrapped metal sleeve. It can be bent and shaped under the action of external force to facilitate the ligation ring 1 to pass through the back of the vagina. By setting the plastic segment 102, the plastically bendable connecting segment can flexibly adjust its shape according to the physiological structure of the vagina and the requirements of surgical operations, and further adapt to different surgical scenarios, so that the ligation ring 1 can fit the vaginal tissue tightly. The cylindrical cassette 103 provides a stable and reliable structural basis for the ligation. The synergistic effect of the three greatly facilitates the implementation of laparoscopic vaginal cerclage operations.
[0029] The cassette 103 is made of nylon or polyethylene and has a cylindrical structure and an annular groove, which avoids the non-fitting and loose cerclage caused by the rotation of the rolling belt of the conventional ligation ring 1. By setting the cassette 103 and the unique design of the flat clamp head 101 and the smooth transition with the cassette 103, during laparoscopic operation, it can smoothly pass through the narrow wound and the limited space in the abdominal cavity, reduce jamming and obstruction, and facilitate accurate arrival at the vaginal cerclage site.

The vaginal cerclage auxiliary rod 2 indicates the vaginal resection length through the distance between the functional end 201A and point B. The vaginal cerclage auxiliary rod 2 provides doctors with an intuitive and accurate vaginal resection length reference standard by using the pre-set fixed distance between the functional end 201A and point B. Doctors can perform vaginal resection operations accurately based on this. During the operation, the cerclage ring 1 can firmly fix the vagina in the groove of the auxiliary rod functional end 201.
[0031] The diameter of the functional end 201A point is greater than the diameter of the functional end 201B point. The ligation ring 1 fixes the vagina at the groove of the functional end 201 to prevent the ligation ring 1 from falling off and assist in the removal of excised tissue.

[0032] The clamp head 101, the plastic segment 102 and the cassette 103 are integrally formed, and the internal components of the clamp head 101 are distributed in a ring shape. By arranging the clamp head 101, the plastic segment 102 and the cassette 103 to be integrally formed, the process of laparoscopic vaginal cerclage can be facilitated.
[0033] The operating rod 202 of the vaginal cerclage auxiliary rod 2 is provided with anti-slip textures, and the functional end 201 and the operating rod 202 are integrally formed. By setting the operating rod 202 of the vaginal cerclage auxiliary rod 2 is provided with anti-slip textures, the functional end 201 and the operating rod 202 are integrally formed, the vaginal cerclage auxiliary rod 2 is used to accurately indicate the vaginal resection length, thereby reducing the shedding of the ligation ring 1 after the vagina is cut.
[0034] Working principle: When using the device, the medical staff will first check the environment around the entire device and its own status. After the inspection, if any problems are found, they will be solved in time before proceeding with the subsequent process. In the ligation ring 1, the unique design of the flat head 101 and the smooth transition with the cassette 103 can smoothly pass through the narrow incision and the limited space in the abdominal cavity during laparoscopic operation, reducing jams and obstacles, and facilitating accurate arrival at the vaginal cerclage site. The plastically bendable connecting section can flexibly adjust its shape according to the physiological structure of the vagina and the needs of surgical operations, further adapting to different surgical scenes, so that the ligation ring 1 can fit the vaginal structure tightly. The cylindrical cassette 103 provides a stable and reliable structural foundation for the ligation. The synergistic effect of the three greatly facilitates the laparoscopic vaginal cerclage operation. When the vaginal cerclage auxiliary rod 2 is working, the pre-set fixed distance between the functional end 201A and point B is used to provide the doctor with an intuitive and accurate vaginal resection length reference standard, and the doctor can accurately perform the vaginal resection operation based on this. In addition, during the operation, the ligation ring 1 can firmly fix the vagina to the groove of the auxiliary rod functional end 201. This fixing method effectively avoids the accidental fall-off of the ligation ring 1 during operations such as vaginal cutting, preventing tumor tissue from On the other hand, after the uterus and related tissues are removed, the removed tissue can be easily taken out of the body along the auxiliary rod channel by means of the connection and fixation between the cervical ligation ring 1 and the auxiliary rod, which optimizes the surgical process and improves the safety and convenience of the operation. First, the medical staff carefully inserts the vaginal cervical ligation auxiliary rod 2 into the vagina until its grooved functional end 201 firmly supports the cervix, providing a stable support and positioning basis for subsequent operations. Then, the medical staff uses the laparoscopic operation hole as a channel to smoothly deliver the cervical ligation ring 1 into the pelvic area. Subsequently, the medical staff uses the operating forceps to accurately position the cervical ligation ring. The connecting portion 8 of the ring 1 is bent and shaped by 90° to better adapt to the anatomical structure of the vagina and the requirements of the surgical path. After that, the medical staff manipulates the operating forceps to make the shaped ligation ring 1 pass through the back of the vagina, and let the cylindrical clasp 103 with annular clamping teeth pass through the clamping hole, so as to tightly fix the vaginal wall to the groove of the cerclage vaginal auxiliary rod 2, and then slowly and steadily tighten the clasp 103 to ensure the firmness and effectiveness of the ligation. Finally, the medical staff accurately indicates the vaginal resection length according to the established distance between points A and B on the cerclage vaginal auxiliary rod 2, and uses the circumcision instrument to perform circumcision on the vagina. After the circumcision is completed, the cerclage vaginal auxiliary rod 2 is slowly pulled outward, and the resected tissue is completely removed from the vagina with the help of the synergistic effect of the ligation ring 1 and the auxiliary rod, so as to complete the key operation steps in the entire surgical process, or there are alternative solutions including designing a cylindrical clasp clasp 103, other shaped ligation ring 1 connecting parts, and changing the relevant directions of the double-layer clamping teeth in the clamp head 101.
