Hysteroscopy Instruments: Names, Functions and Care

Instruments that pass through the working channel

Office hysteroscopes with a 5 Fr channel use semi-rigid or flexible instruments of about 1.7 mm. The core set is small and each item has a clear job.

Always confirm that the instrument length matches the sheath of your hysteroscope, because a channel instrument that is too short cannot open its jaws beyond the tip.

Semi-rigid instruments are inserted with the optic in position and advanced under vision, so handle the tip gently: the jaws and scissors blades are only fractions of a millimetre thick, and a bent shaft will jam in the channel and can damage the seal.

• Grasping forceps: retrieval of small tissue fragments and a lost IUD
• Biopsy forceps: directed sampling of the endometrium, hence hysteroscopy biopsy under vision
• Scissors: dividing thin adhesions or a septum, and cutting polyp stalks
• Bipolar electrodes: needle or ball tips for coagulation and fine cutting, used in saline

Hysteroscopy forceps and scissors: what to check

Hysteroscopy forceps and scissors are fine mechanisms. Check that the jaws close completely, that the cutting edges meet along their full length and that the shaft is straight with no kinks. Ask whether the inserts are replaceable, as this affects the cost of ownership.

Disposable instruments avoid reprocessing but add a recurring cost; reusable ones need rigorous cleaning and function testing, see hysteroscope cleaning and reprocessing.

Whichever route you choose, ask the supplier how many 5 Fr instruments are normally kept per optic, because hysteroscopy biopsy lists and turnover between patients often require two or three of each type.

Cervical access and gynaecological hand instruments

Even with a no-touch approach, a hysteroscopy set is usually accompanied by a few conventional instruments: vaginal specula, a tenaculum or volsellum for stabilising the cervix, uterine sounds to assess depth, and Hegar dilators where dilation is needed.

These are standard gynaecological items. REDA's gynecology instruments range includes Cusco, Pederson, Collin and Sims specula, Hegar uterine dilators, uterine sounds, curettes, tenaculum and biopsy punch forceps. For a broader list see gynecology instruments names and uses.

Operative hysteroscopy instruments beyond 5 Fr

When pathology is larger, the instrument tier changes: a resectoscope with loop or vaporisation electrodes, or a mechanical tissue-removal system. The Richard Wolf Princess resectoscope is a slim 7 mm (21 Fr) example for monopolar and bipolar resection, with a rotating double sheath and BIVAP bipolar vaporisation electrode.

Operative work also needs a matched energy source and fluid control, so instrument selection should always be made together with the generator and pump.

A common mistake is to buy electrodes first and discover later that the generator has no matching hysteroscopic program. Ask for a written compatibility statement covering electrodes, cable, generator and the fluid used for distension (saline for bipolar, a non-electrolyte solution for monopolar).

Hysteroscope set: building a sensible list

A hysteroscope set typically includes telescope, sheaths, light cable, camera coupler, channel instruments and a container to protect them. Request an itemised quotation that names each part and its quantity. Our hysteroscope parts explanation can serve as a checklist.

Care matters: rinse immediately after use, never force jaws, protect optics from impacts, and store instruments in dedicated holders. Beckfinity specialists can help you assemble a hysteroscopy set; contact us for a quote or consultation.
