Description

Technical Field

[0001] The present invention relates to a gynecological surgery auxiliary device. Background Art

[0002] The uterus is located in the pelvic cavity, with the cervix connected to the apex of the vagina. Naturally, the vagina is closed. During uterine surgery, especially cervical surgery, a rigid duckbill dilator or rigid anterior and posterior single-leaf retractors are used to expose the cervix. However, due to anatomical factors such as the narrower vaginal opening relative to the circular vault at the apex of the vagina, and the cervix's location deep within the vagina and its distance from the vaginal opening, the cervix cannot be fully expanded in a circular manner to display the vaginal vault and cervix. This can lead to missed diagnoses and difficult surgical treatment. Rigid duckbill dilators are prone to slipping during surgery, and anterior and posterior vaginal retractors are difficult to secure automatically, requiring the surgeon to hold them in place, hindering surgical procedures. Rigid dilators and retractors, in particular, not only fail to fully expand the vagina in a circular manner but also occupy the already narrow vaginal space, obstructing the surgical path. Furthermore, the rigid instruments forcefully pull on the perineum and vagina, causing physical and psychological discomfort for the patient.

[0003] At present, when patients with cervical cancer or cervical HPV infection use electric surgical instruments to cut, a large amount of smoke is produced, which is harmful. The clinical application of a single smoking tube to suck at one point is less effective. The smoke diffused in the vagina not only affects the vision, but also easily spreads from the vagina to the air in the operating room. Inhalation of surgical smoke is harmful to the health of doctors and patients. Summary of the Invention

[0004] The present invention is designed to avoid the shortcomings of the above-mentioned prior art and adopts a combination technology of an annular porous elastic ring, a smoking tube, a vaginal dilator, a contraction ring and an inserted fixed handle. The porous elastic ring of the present invention can be deformed to pass through the narrow vaginal opening and be erected at the top of the vagina to fully expand and display the cervix, with a wide surgical field of view. The porous elastic ring stands upright and stably under the grasp of the inserted fixed handle and will not slip or twist. After tightening the vaginal dilator, the cervix is ​​pulled toward the vaginal opening, shortening the distance and facilitating surgical operations. The annular porous smoking effect of the porous elastic ring at the top of the vagina is significant, the field of view is fast and clear, which helps to avoid interference from diffuse smoke and protect the health of doctors and patients.

[0029] The surgeon holds the handheld handle portion (320) inserted into the fixed handle, pulls the telescopic button (32) backward to the farthest end, snaps the porous elastic ring (21) into the rotating buckle (311), pushes the telescopic button (32) forward to allow the track slide plate (33) to cover the porous elastic ring (21) so that it can rotate and not fall off, and can control the porous elastic ring (21) to rotate between horizontal and 90 degrees, and adjusts the three-way pipe (211) that keeps the porous elastic ring (21) to be located on the side of the rotating buckle (311) to open the surgical field of view.

[0030] Install the buckle support plate (11), and install the vaginal anterior wall support plate (1) at the corresponding upper end of the porous elastic ring (21) on which the rotating buckle (311) is installed. First, buckle the buckle (111) of the buckle support plate (11) on the porous elastic ring (21), and then insert the pin end (123) of the anti-drop pin plate (12) from the far end of the pin hole (113) of the buckle support plate (11), and control the porous elastic ring (21) to rotate in the buckle (111) without falling off, thereby ensuring that the vaginal anterior wall support plate maintains a horizontal support function.

[0031] To install the telescopic support plate (13), first insert the telescopic support plate (13) into the upper telescopic hole (112) of the buckle (111) end of the buckle support plate (11), and then install the adjustment pin (14) in the anti-falling countersunk hole (132) of the telescopic support plate (13). The double-sided sliding limit hook (131) provided at the rear end of the telescopic support plate (13) can prevent the telescopic support plate (13) from being excessively stretched forward.

[0032] Before inserting the vaginal flexible conformable expansion protective sleeve for uterine surgery into the vagina, first rotate and flatten the porous elastic ring (21) and the vaginal front wall support plate (1), and push the telescopic button (32) forward to lock the track slide plate (33) with the slide plate buckle slope (121), press and hold the telescopic button (32) and hold the insertion part (319) of the insertion fixed handle (31) to insert the vaginal front wall support plate (1) and the porous elastic ring (21) deep into the vagina, slightly withdraw the telescopic button (32), pull the vaginal expansion sleeve (22) and the contraction ring (23) of the flexible conformable expansion protective sleeve (2), so that the porous elastic ring (21) vertically supports the vagina, and the vaginal front wall support plate (1) and the track slide plate (33) physically support the vagina horizontally at the front end of the porous elastic ring (21).

[0033] The vaginal dilation sleeve (22) forms an adaptive channel under the parallel pulling of the front porous elastic ring (21) and the rear contraction ring (23). The contraction ring (23) can be flipped according to the needs of the operation to adjust the appropriate channel size to facilitate cervical surgery under direct vision.

[0034] The inner side surface of the porous outer sheath hose (212) of the porous elastic ring (21) is provided with a plurality of air holes (2121). After being connected to the three-way pipe (211), the smoking pipe (24) and the airtight valve (25), smoke generated by electrocoagulation can be effectively sucked away, thereby ensuring a clear surgical field of view.

[0035] If necessary during the operation, the contraction ring (23) can be connected to the porous cover and used in the laparoscopic state. In order to avoid holding the handle for a long time during the operation, a balance weight can be hung on the hook at the lower end of the handle. After the operation, the handheld handle part (320) is pulled outward, and the porous elastic ring (21) will automatically flatten and exit the vagina.

[0036] The above embodiments are only descriptions of preferred implementation modes of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit and essence of the design of the present invention, any equivalent changes or modifications made to the present invention should be included in the scope of protection of the present invention.
