Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a novel uterine lifter and its method of use. Background Technology

[0002] Uterine lifters are mainly used in gynecological surgeries, especially in endometrial cancer surgery, to effectively support, lift, and fix the uterus, thereby fully exposing the surgical field, facilitating surgical operations, preventing further spread of endometrial cancer lesions, and improving the precision and safety of the surgery.

[0003] In existing technologies, uterine manipulators use a solid structure and are equipped with a manipulator rod. The manipulator rod is inserted into the uterus and used to swing and lift the uterus to the optimal surgical position. However, the solid structure is heavy, and the manipulator rod can easily cause the endometrial cancer lesions to peel off when it is inserted into the uterus. Furthermore, improper operation of the manipulator rod can easily cause uterine perforation, thereby increasing the risk of tumor metastasis and spread. Summary of the Invention

[0004] To address the above problems, this invention provides a novel uterine lifting device and its method of use, the specific technical solution of which is as follows.

[0005] A novel uterine manipulator includes a control handle, a hollow rod, a connecting rod, cervical forceps, and a uterine manipulator cup. The top end of the hollow rod is connected to the bottom of the uterine manipulator cup. A through hole is provided at the center of the bottom of the uterine manipulator cup. One end of the connecting rod passes through the interior of the hollow rod and the through hole of the uterine manipulator cup and connects to the cervical forceps. The other end of the connecting rod is connected to the control handle. The uterine manipulator cup includes a tightening device, which includes an elastic collar disposed at the center of the uterine manipulator cup. The elastic collar has an opening for tightening the outlet of the cervical canal. The connecting rod passes through the opening of the elastic collar.

[0006] Preferably, the elastic collar is located 2-3 cm below the rim of the cup.

[0007] Preferably, the tightening device further includes a pulling device, the upper edge of which is fixed to the inner periphery of the uterine cup, and the lower edge is connected to the elastic collar.

[0008] Preferably, the diameter of the traction device gradually decreases from top to bottom.

[0009] Preferably, the opening diameter of the elastic collar is 2-4 cm.

[0010] Preferably, the cervical forceps can be retracted inside the uterine cup or extend outside the opening of the uterine cup.

[0011] Preferably, the control handle can control the connecting rod to move up or down to extend the cervical forceps outside the cup of the uterine cup, or to retract the cervical forceps inside the uterine cup; the hollow rod includes a first bolt, which is used to lock the position of the connecting rod.

[0012] Preferably, the cervical forceps includes at least two clamps, which have a serrated anti-slip structure.

[0013] Preferably, the control handle includes a second bolt for securing the two clamps of the cervical forceps.

[0014] A method for using a novel uterine lifting device includes the following steps:

[0015] Step S1: Insert the novel uterine lifter into the vagina, adjust the position of the novel uterine lifter, operate the control handle to move upward, and extend the cervical forceps from the opening of the uterine lifter cup;

[0016] Step S2: After the cervical forceps are extended and reach the cervix, the control handle is operated again to gradually close the two clamps of the cervical forceps to clamp the cervix, and the two clamps are fixed by the second bolt.

[0017] Step S3: Move the control handle downwards to pull the cervix downwards into the uterine cup using the cervical forceps. Simultaneously, move the uterine cup upwards towards the vaginal fornix until the cup opening is flush against the vaginal fornix. During the upward movement of the uterine cup, the uterine cup, through the traction device, drives the elastic collar upwards along the cervical forceps and cervical canal until the elastic collar passes above the cervical forceps and fits on the outer surface of the cervical canal to tighten the opening of the cervical canal. Fix the position of the connecting rod with the first bolt.

[0018] Beneficial effects

[0019] This invention provides a novel uterine lifting rod, which has the following advantages compared with the prior art:

[0020] (1) The novel uterine lifter of the present invention, by setting a hollow rod and placing the connecting rod inside the hollow rod, reduces the overall weight of the uterine lifter on the one hand, and eliminates the uterine lifter rod that enters the uterine cavity, instead using cervical forceps to clamp the cervix, which can effectively prevent the uterine lifter rod from entering the uterine cavity and causing the peeling of endometrial cancer lesions. At the same time, it avoids uterine perforation caused by improper operation when placing the uterine lifter rod, thereby increasing the risk of tumor metastasis and spread.

[0021] (2) The cervical forceps set at the front end of the connecting rod can extend from the uterine cup to effectively clamp the cervix, avoiding cutting the vaginal wall tissue during the operation. When the uterus is removed, the uterus will fall into the uterine cavity, preventing the endometrial tissue from flowing out and causing further spread.

[0022] (3) The present invention also includes an elastic tightening device inside the uterine cup. The tightening device includes an elastic collar that can bind the cervical canal to prevent tissues in the uterine cavity, especially cancerous tissues, from flowing out of the cervical canal and causing cancer cells to spread further.

[0023] (4) The present invention features a cervical forceps that can extend and be stored in a cervical cup. An elastic ring is connected to the inside of the cervical cup via a traction device. After the cervical forceps extend out of the cervical cup to clamp the cervix, the control handle is operated to pull the cervix downward into the cervical cup via the cervical forceps. At the same time, the cervical cup moves upward toward the vaginal fornix until the cup opening is close to the vaginal fornix. This is beneficial for identifying the vaginal fornix during the operation, making it easier to detach the vagina at the vaginal fornix. On the other hand, during the upward movement of the cervical cup, the cervical cup moves the elastic ring along the cervical forceps and cervical canal via the traction device until the elastic ring passes above the cervical forceps, thus cleverly placing the elastic ring on the outer surface of the cervical canal to tighten the opening of the cervical canal.

[0026] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] This embodiment discloses a novel uterine lifter, including control handles 81 and 82, a hollow rod 4, a pair of connecting rods 51 and 52 (not shown in the figure), cervical forceps 91 and 92, and a uterine lifter cup 1. The top end of the hollow rod 4 is connected to the bottom of the uterine lifter cup 1. A through hole is provided at the center of the bottom of the uterine lifter cup 1. One end of the connecting rods 51 and 52 passes through the interior of the hollow rod 4 and the through hole of the uterine lifter cup 1 and is connected to the cervical forceps 91 and 92 respectively. The other end is connected to the control handles 81 and 82 respectively. The uterine lifter cup 1 includes a tightening device, which includes an elastic collar 2. The elastic collar 2 is located in the center of the uterine lifter cup 1 and is located 2-3 cm below the cup mouth plane of the uterine lifter cup 1. The elastic collar 2 has an opening for tightening the outlet of the cervical canal. The connecting rods 51 and 52 pass through the opening of the elastic collar 2.

[0028] Furthermore, the tightening device may also include a pulling device 3, the upper edge of which is fixed to the inner periphery of the uterine cup, and the lower edge is connected to the elastic collar 2.

[0029] Furthermore, by controlling handles 81 and 82, the connecting rods 51 and 52 can be moved up or down to retract the cervical forceps 91 and 92 inside the uterine cup 1 or extend them outside the cup opening of the uterine cup 1; a fixing bolt 6 is provided on the hollow rod 4 to lock the position of the connecting rods 51 and 52.

[0030] The method of using the novel uterine lifting device provided in this embodiment includes the following steps.

[0031] Step S1: Insert the new type of uterine lifter into the vagina, adjust the position of the new type of uterine lifter, operate the control handles 81 and 82 to move the connecting rods 51 and 52 upward, and extend the cervical forceps 91 and 92 from the cup opening of the uterine lifter cup 1.

[0032] Step S2: After the cervical forceps 91 and 92 reach the cervix, operate the control handles 81 and 82 again to gradually close the jaws of the cervical forceps 91 and 92 to clamp the cervix.

[0033] Step S3: Operate the control handles 81 and 82 downwards to pull the cervix downwards into the interior of the lifting cup 1 using cervical forceps 91 and 92. At the same time, the lifting cup 1 moves upwards towards the vaginal fornix until the cup opening is close to the vaginal fornix. During the upward movement of the lifting cup 1, the lifting cup 1 drives the elastic collar 2 to move upwards along the cervical forceps 91 and 92 and the cervical canal through the traction device 3 until the elastic collar 2 passes above the cervical forceps 91 and 92 and is placed on the outer surface of the cervical canal to tighten the opening of the cervical canal. The position of the connecting rod is fixed by the second bolt 7.

[0034] Preferably, the opening diameter of the elastic collar 2 is 2cm-4cm, which is used to ensure that the cervical forceps 91, 92 and the cervical canal can pass through the opening in step S3, and the elastic collar 2 can finally be placed on the cervical canal with a larger upward diameter.

[0035] Preferably, the clamps of cervical forceps 91 and 92 have a serrated anti-slip structure.

[0036] The uterine lifting device provided in this embodiment has the following advantages:

[0037] (1) The cervical forceps are designed to extend and retract into the cervical cup. An elastic ring is connected to the inside of the cervical cup via a traction device. After the cervical forceps extend and clamp the cervix, the control handle is operated to pull the cervix downwards into the cervical cup via the forceps. Simultaneously, the cervical cup moves upwards towards the vaginal fornix until the cup opening is flush against the vaginal fornix. This facilitates identification of the vaginal fornix during the procedure, making vaginal transection easier. Furthermore, during the upward movement of the cervical cup, the traction device pulls the elastic ring upwards along the forceps and cervical canal until the elastic ring passes above the forceps, cleverly securing the elastic ring to the outer surface of the cervical canal to tighten the opening. This prevents intrauterine tissue, especially cancerous tissue, from flowing out of the cervical canal, thus preventing further spread of cancer cells.

[0038] (2) By setting a hollow rod and placing the connecting rod inside the hollow rod, the overall weight of the uterine lifter is reduced on the one hand, and the uterine lifter rod that enters the uterine cavity is eliminated on the other hand. Instead, the cervical forceps are used to clamp the cervix, which can effectively prevent the uterine lifter rod from entering the uterine cavity and causing the endometrial cancer lesion to peel off. At the same time, it avoids uterine perforation caused by improper operation when placing the uterine lifter rod, thereby increasing the risk of tumor metastasis and spread.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
