Instrument for occlusion of uterine blood vessels

Abstract

A surgical instrument for at least partially occlusion of the uterus blood vessels during a cesarean section comprising two jaws movable relative to each other to at least partially occlude the uterus blood vessels, latching mechanism to retain the jaws the in the working position over needed period of time and release the jaws when the need for occlusion is over,a disposable tubular cover on the end member of each jaw, said end member of a jaw is connected with the other member of the jaw with an angle 25-45 degrees, preferred angle is 30-45 degrees, said cover has an inner cavity open from one end for receiving and retaining the jaw, the thickness of the side of the cover to be engaged with the blood vessels is 3-15 mm, preferably, 8-12 mm, the width of said cover is 10-30 mm, the length of said cover is 50-60 mm, and said cover made of gauze or fabric.

Description

FIELD OF THE INVENTION[0001]The present invention relates to medical instruments and more particularly to the instruments for occlusion of the uterine blood vessels used in performing the surgical operation cesarean section and other surgical procedures.BACKGROUND OF THE INVENTION[0002]At the present time the cesarean section is one of the most widely used surgical procedures. A cesarean section is a major surgical procedure in which a baby is removed from the uterus by making a cut into the abdomen and then into the uterus. In many cases, a cesarean section is necessary to save the life of the baby or the mother. In other cases, a cesarean section is performed when a vaginal birth is not possible, e.g., failure of normal progression of labor. In some other cases, a cesarean section may be scheduled due to a patient's request, or recommended by another doctor.[0003]The cesarean section begins with an incision or cut on the skin. This cut is carried deeper until the abdomen is comple...

Problems solved by technology

One of the biggest problems related to a cesarean section is blood loss.

Even though the time of the suturing of the uterus is relatively short (about 5-10 minutes), the patient could lose a significant amount of blood just during the suturing of the uterus alone.

It is expensive process, has to be planned in advance and is time consuming.

Due to expense and invasive nature of the procedure, it has a very limited application.

Placing the uterine artery balloon is a temporary procedure, but is still limited by the cost and invasive nature of the procedure.

However, these clamps could not be used for occlusion of the uterine arteries during a normal cesarean section where there is no need for a hysterectomy for a number of reasons.

The clamp damages the uterine arteries and damage during cesarean section could be life threatening.

The profile of the clamp does not fit the abdomen of the patient during cesarean section.

Since it is difficult to occlude an artery only, the clamp has to occlude both the uterine artery and the vein which goes along the artery.
