Abstract

The utility model relates to an auxiliary device used in obstetrics and gynecology, which mainly solves the disadvantages of conventional laparoscopic hysterectomy, such as high difficulty in operation, long operation time, and other complications. The utility model is characterized in that the dome top ring with scissors guide grooves on the upper surface is concentrically connected with the support ring through at least two support columns, the support ring is concentrically connected with the support force column through at least two oblique support columns, and the support force column is opened inwardly. There is a conical hollow that can coincide with the cone of the palace lifter. The adoption of the utility model is beneficial to the rapid popularization of laparoscopic total hysterectomy.

Description

vaginal pessary

The utility model relates to an auxiliary instrument used in obstetrics and gynecology, in particular to an instrument for laparoscopic hysterectomy.

In conventional laparoscopic total hysterectomy, the vagina is filled with blue gauze (because there is no blue color in the human body, it is easy to distinguish during the operation), so that the vaginal fornix is expanded so that it can be resected under the laparoscope. The disadvantages of removing the uterus after the vaginal vault are as follows: 1. Because the gauze is soft, the inflated vaginal vault is inaccurate; 2. Because the cervicovaginal part prevents the gauze from entering the top of the vault, the connection between the vault and the uterus does not protrude toward the abdominal cavity , which increases the difficulty of operation during intraperitoneal resection of the vaginal vault, and easily leads to other complications; 3. Due to the inability to control and swing the uterus, the operation time is prolonged.

The purpose of this utility model is to provide a vaginal pessary that can greatly facilitate operation, reduce operation difficulty, shorten operation time, improve operation safety and effectiveness, and reduce operation complications.

The utility model can be realized in the following manner:

The dome top ring with scissors guide grooves on the upper surface is concentrically connected with the support ring through at least two support columns, and the support ring is concentrically connected with the support force column through at least two oblique support columns. A conical hollow that coincides with the cone.

The above-mentioned dome top ring and support columns are all made of insulating and high-temperature-resistant colored materials.

The utility model can make the incision part of the vaginal dome protrude to the abdominal cavity, avoiding damage to other organs in the pelvic cavity due to electric diffusion, and the scissors guide groove on the top ring of the dome can prevent damage to the surrounding organs caused by the sliding of the scissors during surgical cutting. Combined with the use of existing instruments such as uterine lifters and cervical forceps, the vaginal vault can be better protruded to the abdominal cavity and the movement of the uterus can be controlled, thereby reducing the difficulty of the operation, improving the safety of the operation, and making the operation easier , conducive to the rapid promotion of laparoscopic hysterectomy.

Accompanying drawing 1 is the utility model sectional structure schematic diagram.

Accompanying drawing 2 is the utility model top view structure diagram.

In the figure: 1—scissors guide groove, 2—dome top ring, 3—supporting column, 4—supporting ring, 5—oblique supporting column, 6—supporting force column, 7—conical hollow, 8—a palace lifter.

Embodiment is further described below in conjunction with accompanying drawing:

The dome top ring 2, support column 3, support ring 4, oblique support column 5 and support force column 6 are all made of phenolic resin material with a diameter of 5mm, wherein: the inner diameters of the dome top ring 2 and the support ring 4 are both 30mm, The upper surface of the dome top ring 2 is provided with a scissors guide groove 1 with a blue logo, and the length of the support column 3 and the oblique support column 5 are both 20mm, and there are three each, which are evenly distributed at an angle of 120 degrees, and support the force column 6. Diameter 20mm, high 15mm, minimum diameter (upper mouth) 0.8mm, maximum diameter (lower mouth) 15mm of tapered hollow 7, assemble each parts by aforementioned mode and promptly become the utility model. During the operation, the dome ring 2 can lift the dome and protrude to the abdominal cavity, the scissors guide groove 1 near the cervical edge can fix and guide the movement of the scissors, and the hollow part between the dome ring 2 and the support ring 4 can accommodate the cervix and vagina Through the support ring 4, the upper cervical forceps can clamp the cervix and pull the cervix downward, and the uterine lifter 8 that enters the uterine cavity through the tapered hollow 7 can conveniently control the activities of the uterine body, such as fixation, front and rear, left and right, etc. Movement, etc., in order to facilitate the operation.

Claims (2)

1. A vaginal pessary, characterized in that the dome top ring with scissors guide grooves on the upper surface is connected concentrically with the support ring by at least two support columns, and the support ring is concentrically connected with the support force column by at least two oblique support columns, There is a conical hollow in the supporting force column that can match the cone of the palace lifter. 2. A vaginal pessary according to claim 1, characterized in that said dome top ring and support columns are made of insulating and high-temperature-resistant colored materials.
