When cleaning the uterine cavity, plastic tubes are required (such as removing blood clots, mucus, debris, and cleaning liquids mixed with blood). These guide tubes must be thick enough to achieve flushing without being blocked by clots. Its endoscope ranges from 1.6 to 2.9mm, with an outer diameter of 2.0 to 3.0mm.

Some types of plastic tubes can barely be used as attractants, but they are often too short to connect well with the syringe. Some attractors have a 1mm mark at the end for measurement purposes. The length of the recruitment tube is between 35-100cm and it is equipped with a rotary lock interface to facilitate the connection of a simple leak proof syringe. These attractors can attract debris outside the cervix. Liquid media can be flushed into the cervix through an attractor. Because the attractor can move freely back and forth, there is no need to rely on an optical system. Most experienced physicians can freely and frequently use attractants. Attempting to reduce the use of endoscopic observation during surgical procedures often leads to unnecessary wounds. Quietly attracting debris can make the murky view very clear, which is valuable in saving time. A new type of 3mm diameter attractor can also be used to attract pathological specimens. The new equipment will connect the flushing function and attraction function together, forming a single device

Electrodes:

Some types of electrodes can pass through the operating sheath. With the recent improvement of the thick (3mm) operating sheath, a new type of special electrode with both unipolar and bipolar modes has been introduced. These electrodes can perform all the work that an electrocautery mirror can do. Among them, unipolar electrocoagulation includes a 2.5mm button shaped electrode, electrode needle, and a flexible point cutting ring

Operation switch

Most operation sheaths are equipped with an independent operation channel. The operation channel is equipped with a valve, which is controlled by the switch of the valve to prevent leakage of uterine fluid. When soft instruments, electrodes, semi hard instruments, laser beams, or attractors need to pass through the operating sheath, the operating sheath should be equipped with washers or threaded joints to avoid leakage. Until recently, a rubber joint in urology was modified for use in hysteroscopes

Some of these joints have oversized openings, to the extent that liquid leaks when fine instruments are pushed in. The joints with only needle tip and narrow openings are most suitable for hysteroscopic surgery

A type of alternating operating gasket that is connected to the operating sheath through a rotary interface has now been developed. The planning of this switch avoids slipping. Additionally, the exquisite blade design of the gasket allows for limited passage of the fine laser beam, thereby reducing the exposure of the medium.
