Description

UTERINE MANIPULATOR

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a uterine artery, and more particularly, to a uterine artery for easily manipulating the movement of the uterus during laparoscopic surgery.

Hysterectomy is the most common form of surgery performed in gynecologists. In the past, abdominal hysterectomy with laparoscopic hysterectomy was performed, but laparoscopic hysterectomy has been widely used recently.

Laparoscopic surgery has several advantages over open surgery. In other words, it can be expanded anatomically and pathologically from the technical point of view, and access to surgery, quality and rectum is easy. In addition, laparoscopic surgery has the advantage of reducing the possibility of intestinal adhesion because the internal organs of the abdominal cavity are not exposed to the atmosphere. In addition, the advantages of laparoscopic surgery for patients with abdominal incision are very few, very superior to cosmetic surgery, less pain, shorter hospital stay, faster return to daily life, infection rate and intestinal obstruction It is extremely small, and there is little bleeding.

Recently, laparoscopic surgery for cervical cancer has been performed. The operation of the uterus in hysterectomy and uterine myomectomy is the essential procedure of laparoscopic surgery in the field of gynecology as the basis of uterine surgery.

The laparoscopic surgery can shorten the operation time by facilitating the operation of the uterus. The uterus can be manipulated in the front and back of the uterus, but the operation of the uterus can not be performed. There is a face that is lacking in height.

FIG. 10 is a cross-sectional perspective view showing the airbag section of the uterus according to an embodiment of the present invention, FIG. 11 is a cross-sectional view illustrating a first adapter of the uterus according to an embodiment of the present invention, And FIG. 12 is an exemplary view illustrating the use of the uterus according to an embodiment of the present invention.

10 to 12, the airbag portion 700 may have an inner portion 710, a first expanding portion 720, and a second expanding portion 730.

The inner portion 710 may have a mounting ring 711 coupled to the mounting groove 313 of the receiving portion 300 and may extend in the longitudinal direction of the coupling cap portion 310 while surrounding the coupling cap portion 310. [ have.

The first bulging portion 720 may be connected to the inner portion 710 and may be formed to surround a part of the outer peripheral surface of the inner portion 710. A first tube 721 may be connected to the first bulging portion 720 and a first adapter 722 may be connected to one end of the first tube 721. When an air supply unit (not shown) for supplying air is connected to the first adapter 722 to supply air, the air is supplied to the first bulging portion 720 through the first tube 721 and is filled therein, The expanding portion 720 may expand.

The first bulging portion 720 can seal the interior of the vagina 10 while expanding, thereby preventing gas from escaping through the cut vagina when the vagina is cut during surgery.

A check valve 723 may be provided inside the first adapter 722. The check valve 723 may be coupled with an air supply unit. The air supply part may be a syringe and the check valve 723 may be opened by air pressure when air is supplied through the air supply part. When the air supply through the air supply part is stopped, the check valve 723 can be closed by the air pressure in the first tube 721.

When an air supply unit (not shown) for supplying air is connected to the second adapter 732 to supply air, the air is supplied to the second expansion unit 730 through the second tube 731 to be filled therein, The expanding portion 730 can expand.

The second expanding portion 730 can seal the inside of the vagina 10 while expanding so that when the vagina is cut during surgery, the gas may not flow out through the cut vagina. The second bulging portion 730 may be formed independently of the first bulging portion 720. That is, the airbag portion 700 has the shape of the double airbag by having the first inflating portion 720 and the second inflating portion 730.

As a result, even if one of the first bulging portion 720 and the second bulging portion 730 ruptures, the other one can prevent the outflow of the gas. The second adapter 732 may be provided with a check valve as described above. After the second expansion part 730 is inflated, the second stopper 735 may block the check valve to prevent air from being discharged .
