Description

Medical one-touch 3-way stopcock

The present invention relates to a medical 3-way stopcock, which allows medical staff to freely perform suction and cleaning without removing the suction device by connecting the one-touch 3-way stopcock to a connecting tube.

Conventional spine surgery involves making a relatively large incision to open the spine to the outside, causing various problems such as severe pain and long recovery time, so minimally invasive surgery is becoming increasingly common.

This minimally invasive surgery involves inserting a catheter percutaneously into the lesion area under local anesthesia with minimal incision and then performing the necessary treatment.

Recently, spinal endoscopy using this minimally invasive method is being performed by cutting the skin and inserting the tools necessary for spinal endoscopy.

In particular, Unilateral Biportal Endoscopy (UBE) is sometimes performed, which is a surgical method that involves making two small holes in the skin, inserting a spinal endoscope into one hole and inserting the tools necessary for the surgery into the other hole. It has the advantage of minimizing damage to tissues, including muscles, and having almost no surgical infection.

An important point in this kind of spinal endoscopy is securing an accurate field of view. This is because quick and effective treatment cannot be performed if the lens at the tip of the endoscope is obscured by body tissue or internal bleeding blood. Ensuring visibility is important not only in spinal endoscopy but also in arthroscopic surgeries such as knee and shoulder surgery.

For this purpose, surgical tools are being developed, and in addition to ablation for lesion treatment, high-frequency treatment devices are used to remove soft tissue or ligaments to secure the endoscope's field of view, and to achieve hemostasis.

This high-frequency treatment device is connected to a generator and immediately removes soft tissues or ligaments in the body that interfere with vision during surgery, enables rapid hemostasis, and discharges contaminants out of the body by passing saline solution through the treatment area. This makes effective surgery possible.
