Abstract
Description
Technical Field
[0001] This invention belongs to the field of medical device technology, specifically, it relates to a magnetic anchoring traction uterine lifting component and method for preventing the spread of cancer cells during surgery. Background Technology
[0002] Cervical cancer is the most common malignant tumor of the female reproductive tract in my country, seriously threatening women's health. The main treatment for cervical cancer is radical hysterectomy. With the popularization of minimally invasive surgical techniques, laparoscopic surgery for cervical cancer, which is less invasive, is gradually being promoted. Laparoscopic surgery has advantages such as clear visualization, clear anatomy, less bleeding, faster recovery, and shorter hospital stay. However, patients undergoing minimally invasive cervical cancer surgery have a higher risk of recurrence and death compared to those undergoing open surgery, raising concerns in the academic community about laparoscopic cervical cancer resection. Possible adverse outcomes from minimally invasive cervical cancer surgery are related to factors such as the use of uterine manipulators, CO2 pneumoperitoneum, the extent of parametrial resection, the method of vaginal incision, and surgical field irrigation.
[0003] Existing uterine ligation cups play a guiding and assisting role in minimally invasive surgery for cervical cancer. However, because these uterine ligation cups are located in the low vaginal fornix, they cannot provide large-angle rotation or force support for surgical operations. Furthermore, when the vagina is severed during surgery, existing uterine ligation cups cannot prevent the spread of cervical tumors into the pelvic cavity, and the cervix and pelvis may come into direct contact, leading to tumor dissemination. In view of this, the present invention is proposed. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a magnetic anchoring traction uterine lifting component and method for preventing the spread of cancer cells during surgery. It can support and lift the uterus during surgery to facilitate surgical operation, and detach the uterus after the cervix is closed to prevent the spread of cervical tumors.
[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:
[0006] A magnetic anchoring traction uterine lifting component for preventing cancer cell dissemination includes:
[0007] An internal magnetic anchoring device is placed inside the body. The internal magnetic anchoring device includes a receiving part that abuts against the cervix and covers and seals the cervix.
[0008] An external magnetic anchoring device is placed outside the body, and the external magnetic anchoring device adjusts the position of the internal magnetic anchoring device through the attractive force between the external magnetic anchoring device and the internal magnetic anchoring device.
[0009] Furthermore: the in vivo magnetic anchoring device is magnetic, and / or the external magnetic anchoring device is magnetic.
[0010] In some alternative embodiments: the in vivo magnetic anchoring device includes a support having a recessed receiving area, the receiving portion being located in the receiving area, and a guide body of the support extending upward from the middle of the receiving area.
[0011] Furthermore: the in vivo magnetic anchoring device is shaped like an inverted mushroom, the support is a closed umbrella shaped like a mushroom cap, and the guide is shaped like a mushroom stem.
[0012] Furthermore, the in vivo magnetic anchoring device has a mounting through hole.
[0013] Furthermore, the support body and the guide body are integrally formed.
[0014] Furthermore, the mounting through hole extends through the support body and the guide body.
[0015] In some alternative implementations, the receiving part is made of an elastic material.
[0016] Furthermore, in some optional embodiments: the head of the uterine lifting rod is configured as a cavity, and the head of the uterine lifting rod includes an upper part of the head, a middle part of the head, a lower part of the head, a liquid flow section, and a ring section.
[0017] This invention also provides a method for raising the uterus during a magnetic anchoring traction procedure to prevent the spread of cancer cells. This method is used in any of the aforementioned magnetic anchoring traction procedures for preventing the spread of cancer cells. A uterus-raising rod pushes an internal magnetic anchoring device into the vagina. The receiving part of the internal magnetic anchoring device abuts against the cervix and seals it. The uterus-raising rod is then withdrawn from the vagina, leaving the internal magnetic anchoring device inside the body. An external magnetic anchoring device adjusts the position of the internal magnetic anchoring device through magnetic attraction.
[0018] Furthermore, the external magnetic anchoring device controls and adjusts the uterine posture by adjusting the position of the internal magnetic anchoring device through magnetic attraction.
[0019] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.
[0020] This invention provides a magnetic anchoring traction uterine lifting component and method for preventing the spread of cancer cells during surgery. It can support and lift the uterus during surgery to facilitate surgical operations, and detach the uterus after the cervix is closed to prevent the spread of intrauterine tumors.

[0033] like Figures 1 to 3 As shown, the present invention provides a magnetic anchoring traction uterine lifting component for preventing cancer cell dissemination during surgery. This magnetic anchoring traction uterine lifting component for preventing cancer cell dissemination includes:
[0034] An internal magnetic anchoring device 1 is placed inside the body. The internal magnetic anchoring device 1 includes a receiving part 7, which abuts against the cervical opening and covers and seals the cervical opening.
[0035] An external magnetic anchoring device is placed outside the body. The external magnetic anchoring device adjusts the position of the internal magnetic anchoring device 1 by means of the attraction between the external magnetic anchoring device and the internal magnetic anchoring device 1.
[0036] Specifically, the internal magnetic anchoring device 1 is inserted into the vagina without compressing the tumor. When the receiving part 7 of the internal magnetic anchoring device 1 comes into contact with the cervix and seals the cervix, the internal magnetic anchoring device 1 is successfully placed.
[0037] An external magnetic anchoring device is placed outside the body to attract the internal magnetic anchoring device 1. Optionally, for example, it can be located on the abdominal wall. The external magnetic anchoring device adjusts the position of the internal magnetic anchoring device 1 through the attraction between itself and the internal magnetic anchoring device 1. This allows for control and adjustment of the uterine posture.
[0038] This invention provides a magnetic anchoring traction uterine lifting component and method for preventing cancer cell dissemination during surgery. It can support and lift the uterus during surgery to facilitate surgical operations, and detach the uterus after the cervix is closed to prevent the dissemination of cervical tumors.
[0039] like Figures 1 to 3As shown, in some optional embodiments, the present invention provides a magnetic anchoring traction uterine lifting assembly for preventing the spread of cancer cells, wherein the in vivo magnetic anchoring device 1 of the magnetic anchoring traction uterine lifting assembly for preventing the spread of cancer cells is magnetic, and / or the external magnetic anchoring device is magnetic.
[0040] Specifically, the external magnetic anchoring device adjusts the position of the internal magnetic anchoring device 1 by means of the attractive force between the external magnetic anchoring device and the internal magnetic anchoring device 1.
[0041] Optionally, in embodiment 1, the in vivo magnetic anchoring device 1 is magnetic, such as a magnet, while the external magnetic anchoring device is made of ferrous metal material.
[0042] Optionally, in embodiment 2, the in vivo magnetic anchoring device 1 is made of ferrous metal material, and the external magnetic anchoring device is magnetic, such as a magnet.
[0043] Optionally, in embodiment 3, the in vivo magnetic anchoring device 1 is magnetic, such as a magnet. The external magnetic anchoring device is magnetic, such as a magnet.
[0044] Those skilled in the art can choose the implementation method of the above three embodiments as needed. The present invention is introduced in the manner of embodiment 3.
[0045] like Figures 1 to 3 As shown, in some optional embodiments, the present invention provides a magnetic anchoring traction uterine lifting component for preventing the spread of cancer cells. The in vivo magnetic anchoring device 1 of the magnetic anchoring traction uterine lifting component for preventing the spread of cancer cells includes a support body 5, the support body 5 having a recessed receiving area, a receiving part 7 located in the receiving area, and a guide body 6 extending upward from the middle of the receiving area.
[0046] Specifically, the internal magnetic anchoring device 1 is shaped like an inverted mushroom, the support 5 is a closed umbrella shaped like a mushroom cap, and the guide 6 is shaped like a mushroom stem. Further, the guide 6 is a column shaped like a mushroom stem.
[0047] The cap-shaped closed umbrella and the stem-shaped column are connected. The optional support body 5 and guide body 6 are integrally molded, which is convenient for processing and manufacturing.
[0048] Furthermore, the in-body magnetic anchoring device 1 has an installation through hole 4.
[0049] The lifting rod 3 can be inserted into the installation through hole 4 of the inverted mushroom-shaped internal magnetic anchoring device 1, so that the internal magnetic anchoring device 1 can be inserted into the uterus through the vagina.
[0050] In detail, the through hole 4 penetrates the support body 5 and the guide body 6. This facilitates the insertion of the lifting rod 3 into the body and the magnetic anchoring device 1.
[0051] like Figures 1 to 3As shown, in some optional embodiments, the present invention provides a magnetic anchoring traction uterine lifting component for preventing the spread of cancer cells, wherein the receiving part 7 of the magnetic anchoring traction uterine lifting component for preventing the spread of cancer cells is made of elastic material.
[0052] The main body of the internal magnetic anchoring device 1 is made of rigid plastic with embedded magnets. Alternatively, it can be made of metal with embedded magnets.
[0053] The receiving part 7 is located inside the sealing umbrella and abuts against the cervical opening, enveloping and sealing it. Using an elastic material allows for better sealing. The elastic material can be silicone.
[0054] like Figures 1 to 3 As shown, in addition to the aforementioned magnetic anchoring traction uterine lifting component for preventing cancer cell dissemination, this application also provides a method for magnetic anchoring traction uterine lifting to prevent cancer cell dissemination. This method is used in conjunction with the aforementioned magnetic anchoring traction uterine lifting component for preventing cancer cell dissemination. The receiving portion 7 of the internal magnetic anchoring device 1 abuts against the cervix and seals it. The uterine lifting rod 3 is withdrawn from the vagina, leaving the internal magnetic anchoring device 1 inside the body. The external magnetic anchoring device adjusts the position of the internal magnetic anchoring device 1 through magnetic attraction.
[0055] Furthermore, the external magnetic anchoring device controls and adjusts the uterine posture by adjusting the position of the internal magnetic anchoring device 1 through magnetic attraction.
[0056] like Figures 1 to 3 As shown, a specific embodiment will be explained below.
[0057] The internal magnetic anchoring device 1 is shaped like an inverted mushroom, with the support body 5 being a closed cap-like structure and the guide body 6 being a stem-like structure. The guide body 6 is further shaped like a stem-like column. A mounting through-hole 4 penetrates the support body 5 and the guide body 6. The uterine lift rod 3, extending from the support body 5 to the guide body 6, can be inserted into the mounting through-hole 4 of the inverted mushroom-shaped internal magnetic anchoring device 1.
[0058] Without compressing the tumor, the inverted mushroom-shaped internal magnetic anchoring device 1 is inserted into the vagina via the uterine lifter 3. By controlling the uterine lifter 3, the guide body 6 of the internal magnetic anchoring device 1 enters the uterine cavity through the cervix, while the support body 5 connected to the guide body 6 reaches the cervix. The support body 5 is a cap-shaped closed umbrella; when the closed umbrella reaches the cervix, the receiving part 7 on the surface of the closed umbrella wraps and seals the cervix. The guide body 6 is a stem-shaped column with magnetism and an embedded magnet. The receiving part 7 is made of silicone. Alternatively, the support body 5 can also be made of silicone.
[0059] After the receiving part 7 abuts against the cervix and completely seals the cervix, the uterine lifter 3 is withdrawn from the vagina, leaving the internal magnetic anchoring device 1 inside the body. Depending on the surgical field requirements, the external magnetic anchoring device can be placed externally, for example, on the abdominal wall. The external magnetic anchoring device is magnetic and used to attract the internal magnetic anchoring device 1. The external magnetic anchoring device adjusts the position of the internal magnetic anchoring device 1 through the attraction between itself and the internal magnetic anchoring device 1. This traction on the uterus allows for controlled adjustment of its posture, providing the surgeon with a wider surgical field and a better operating environment. The internal magnetic anchoring device 1 continues to seal the cervix after uterine transection, preventing the spread of intrauterine tumors. Furthermore, the internal magnetic anchoring device 1 can be removed along with the removed uterus.
[0060] This invention provides a magnetic anchoring traction uterine lifting component and method for preventing cancer cell dissemination during surgery. It can support and lift the uterus during surgery to facilitate surgical operations, and detach the uterus after the cervix is closed to prevent the dissemination of cervical tumors.
[0061] Figure 4 The diagram shows another type of lifting rod 3 structure. The rod head 300 of the lifting rod is set in a hollow shape. The lifting rod head includes an upper part 301, a middle part 302, a lower part 303, a liquid flow part 304, and a ring part 305.
[0062] A liquid flow channel 306 is provided at the center of the lower part 303 of the rod head, and an auxiliary agent flow channel 307 is provided on the side of the lower part of the rod head. The liquid flow part 304 is installed in the liquid flow channel 306, and a liquid orifice is provided at the center of the liquid flow part 304 (not shown in the figure, but those skilled in the art will understand). The auxiliary agent or other components that need to be used in combination with the treatment flow through the auxiliary agent flow channel 307 from the head of the lower part 303 of the rod head and mix with the treatment agent or main agent flowing out of the liquid orifice, so as to achieve the mixing ratio of main and auxiliary agents or multiple agents or the flushing and disinfection effect during treatment.
[0063] The lower part 303 of the rod head is in the shape of a stepped platform. The lower part 303 of the rod head has a lower step 308, a middle step 309, and an upper step 310 from bottom to top. Along the upward direction of each step, the flowing liquid will be gradually accelerated in the gradually narrowing flow channels, thereby producing a better mixing and rinsing effect.
[0064] The center of the clubhead middle portion 302 has a lower body 311, a middle body 312, and an upper body 313. The upper body 313 has a narrowing hole 314. The lower part of the narrowing hole 304 is a circular hole. The circular hole is fitted with a ring portion 305 (the ring portion is a circular ring with intermittently distributed gaps around its circumference, through which medicine or liquid can flow out; not shown in the figure, but those skilled in the art will understand). The ring portion 305 fixes the lower part 303 of the clubhead in the outlet of the clubhead middle portion.
[0065] The upper part 301 of the rod head is frustum-shaped, and the upper part 301 of the rod head and the middle part 302 of the rod head are an integrated structure. A plurality of first flow channels 315 are evenly distributed between the upper part 301 of the rod head and the middle part 302 of the rod head, and a second flow channel 316 is formed between the middle part 302 of the rod head and the lower part 303 of the rod head. A plurality of third flow channels 317 are evenly distributed on the outer circumference of the upper part 301 of the rod head.
[0066] Those skilled in the art will understand that the step surfaces or edges of the uterine manipulator head are all chamfered and rounded to meet the needs of surgical procedures. Figure 5 shows an enlarged sectional view. The various medications and liquids mix through their respective channels and flow out at the outlet 301 at the top of the manipulator head, forming a mist fluid 318. Due to the addition of many auxiliary cavities, an interactive mixing domain 319 is also formed below the mist fluid, which greatly increases the mixing effect of the medications and thus improves the therapeutic effect. Those skilled in the art will also understand that the uterine manipulator can be made into a hollow tube, with connecting tubes for various medications or liquids inside the hollow tube. Each channel can be connected to each connecting tube. This is conventional prior art in the field and will not be described in detail here.
[0067] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
