【Gynecological Hysteroscopy】Use of Surgical Instruments

Surgical instruments commonly used in surgical hysteroscopy - resectoscope. The resectoscope is mainly composed of the following: the working hand piece, the inner sheath, the outer sheath and the electric cutting ring. The hysteroscopic resectoscope usually adopts a passive working hand piece. When the working hand piece is in the passive position, the electric cutting ring will be recovered. inside the mirror sheath.

Obturator use of bipolar resectoscope

The main purpose is to avoid damage to the lens from objects in front of the body.

Endoscope use

Divided into 12 degrees and 30 degrees, the commonly used 12 degrees, the field of vision is relatively clear.

Operation hand key use

The front end is used to install the electric cutting ring or electric cutting ball. The back and forth movement of the handle completes the cutting of the tissue. The two sides of the handle are used to install the bipolar wire.

Inner sheath use

The front end is an insulating ceramic device to avoid electrical damage to the human body.

Outer sheath use

Perfusion of the system is accomplished by binding to the inner sheath.

The front end is the water inlet and outlet.

Electric cutting ring use

Open 90 degrees is the most widely used electric cutting ring. Main electrode for removal of polyps, fibroids, remnants, etc.

Skill:

① First power off - scrape, then power on - cut.

② Hook the tissue first, then energize, to be accurate and safe.

③ Using the electrocoagulation block, it can directly electrocoagulate to stop bleeding, avoiding the delay of precious hemostasis time by changing spherical electrodes.

Use of electric cutting needle

It is mainly used for incision of the uterine mediastinum and the opening of the fibroid surface.

Assault electrode, mostly used for septum incision and adhesion separation.

Skill:

① Probe the adhesion surface first, then power on and cut.

② Hook the adhesive cable first, then turn on the power, and the hook will break.

③ The use of electrocoagulation can directly stop the bleeding, but it should be noted that the needle tip still has the cutting function under the state of electrocoagulation.

Use of electrocautery

The front end is in the shape of a rolling ball and is mainly used for hemostasis and endometrial cutting.
