Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular, relates to a uterine lifting component and method during magnetic anchoring traction surgery for preventing the spread of cancer cells. Background Art

[0002] Cervical cancer is the most common malignant tumor of the female reproductive tract in my country, which seriously threatens women's health. The main treatment for cervical cancer is (extensive) hysterectomy. With the popularization of minimally invasive surgical techniques, laparoscopic surgery for cervical cancer with less trauma has gradually begun to be promoted. Laparoscopic surgery has the advantages of clear vision, clear anatomy, less bleeding, fast recovery, and short hospitalization time. However, patients undergoing minimally invasive surgery for cervical cancer have a higher risk of recurrence and death than patients undergoing open surgery, which has caused concern in the academic community about laparoscopic cervical cancer resection. The adverse outcomes of minimally invasive surgery for cervical cancer may be related to the uterine manipulator, CO2 pneumoperitoneum, the range of paracervical resection, the method of vaginal incision, and the washing of the surgical field.

[0003] The existing uterine lifting cup plays a guiding and auxiliary role in minimally invasive surgery for cervical cancer. However, since this type of uterine lifting cup is located at the lower vaginal fornix, it cannot provide a large angle of rotation or force support for the surgical operation. Moreover, when the vagina is cut off during surgery, the existing uterine lifting cup cannot prevent the cervical tumor from spreading to the pelvic cavity. The cervix and the pelvic cavity may come into direct contact, resulting in tumor spread. In view of this, the present invention is specially 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 uterine lifting component and method for preventing the spread of cancer cells during magnetic anchoring traction surgery, which can support and lift the uterus during surgery to facilitate surgical operations, and separate the uterus after closing the cervical os to prevent the spread of cervical tumors.

The component and method can support and lift the uterus during surgery to facilitate surgical operations, and can sever the uterus after closing the cervical os to prevent the spread of cervical tumors.

[0061] Figure 4 Another structure of an uterine lifting rod 3 is shown, wherein the rod head 300 of the uterine lifting rod is arranged in a cavity shape, and the rod head of the uterine lifting rod comprises an upper rod head portion 301, a middle rod head portion 302, a lower rod head portion 303, a drug liquid circulation portion 304, and a circular ring portion 305.

[0062] A medicine flow channel 306 is opened in the center of the lower part 303 of the rod head, and an auxiliary medicine flow channel 307 is set on the side of the lower part of the rod head. The medicine circulation part 304 is installed in the medicine flow channel 306, and a medicine hole is opened in the center of the medicine circulation part 304 (not shown in the figure, but those skilled in the art can understand it). Auxiliary medicines or other component medicines that need to cooperate with the treatment flow out from the head of the lower part 303 of the rod head through the auxiliary medicine flow channel 307 and mix with the treatment medicine or the main medicine flowing out of the medicine hole, so as to achieve the mixing ratio or flushing and disinfection effect of the main and auxiliary medicines or multiple medicines in treatment.

[0063] The lower part 303 of the rod head is in the shape of a stepped shaft, and 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 outflowing medicine liquid will be gradually accelerated in the gradually narrowing flow cavities, thereby producing a better mixing and flushing effect.

[0064] The center of the middle part 302 of the club head has a middle lower body 311 of the club head, a middle middle body 312 of the club head, and a middle upper body 313 of the club head. The middle upper body 313 of the club head has a middle narrowed hole 314 of the club head. The lower part of the middle narrowed hole 304 of the club head is a circular hole, and the annular part 305 is installed inside the circular hole (the annular part is a circular ring, and the annular part has gaps evenly distributed intermittently around the circumference, and the medicine or liquid medicine can flow out of the gaps, which is not shown in the figure, but a person skilled in the art can understand it). The annular part 305 fixes the lower part 303 of the club head in the outlet of the middle part of the club head.

[0065] The upper part 301 of the club head is a truncated cone, and the upper part 301 of the club head and the middle part 302 of the club head are an integrated structure.

[0066] Those skilled in the art will appreciate that each step surface or edge surface of the uterine lifting rod head has been chamfered and rounded to meet the needs of surgical operations. FIG. 5 is an enlarged cross-sectional view. Each agent and liquid medicine is mixed through its own channel and flows out at the outlet 301 on the upper portion of the rod head to form a mist fluid 318. Due to the addition of more auxiliary cavities, an interacting mixing domain 319 is formed below the mist fluid, which greatly increases the mixing effect of the agents, thereby improving the therapeutic effect. Those skilled in the art will also appreciate that the uterine lifting rod can be made into a hollow tube, in which each agent or liquid medicine connecting tube is provided, and each channel can be connected to each connecting tube. This is conventional prior art in the field and will not be elaborated here.
