Electrogynecological instruments carry current into the gynaecological field; the specula here are built so the blades stay non-conductive while an electrode works millimetres away. Peak Surgicals supplies five bipolar and electrosurgical specula: Graves, Pederson, Collin and Cusco in German stainless steel, from $27.50 to $49.50. Each is CE marked and built under ISO 13485. Compare all five patterns in the grid below.
Which Bipolar Speculum for Which Procedure?
The Bipolar Graves speculum carries a wider blade for broad cervical exposure, the Bipolar Pederson runs narrower for a tighter or nulliparous canal, the Cusco is the self-retaining duckbill pattern for hands-free access, and the Bipolar Collin suits deeper retraction each built for the electrosurgical field where a diagnostic speculum cannot safely go. Blade width and retention style decide the choice.
Bipolar Graves Vaginal Speculum (PS-1018, from $27.50) gives the widest exposure, standard where the transformation zone must be fully visible. Bipolar Pederson Vaginal Speculum (PS-1023, from $27.50) trades width for a narrower blade a smaller canal tolerates. Cusco Speculum (PS-1015, from $49.50) opens like a duckbill and holds itself open, freeing both the surgeon's hands during excision. Bipolar Collin Speculum (PS-1014, from $44.00) reaches deeper fields, and the Electro Speculum (from $28.60) covers general electrosurgical use. We supply every pattern at MOQ 1.
Why These Instruments Are Built for Current
The difference between an electro gynecology speculum and a diagnostic one is safety in a live field. During electrosurgical procedures, an electrode vaporises tissue, generating surgical smoke and placing radiofrequency current close to the speculum blades. Two design considerations answer those problems, and both are worth confirming against the specific generator system in use.
Insulation is the first. An electrosurgical speculum is built so its blades do not conduct stray current to the vaginal wall — the coating or material achieving this is what makes it compatible with an electrosurgical generator rather than merely present in the field. Smoke management is the second: electrosurgical plume obscures the view and carries vaporised tissue away from the operative site, so instruments built for these procedures route it clear.
Self-retention matters more here than in diagnostic use. The procedure needs both of the surgeon's hands, so a speculum that holds its own position as the Cusco duckbill does — removes the need for an assistant to maintain exposure.
Reprocessing, Insulation Integrity and Certification
Insulation integrity is the safety-critical inspection on any electrosurgical instrument. A breached coating routes current where it was never intended, so check the blades each cycle for coating damage rather than only for cleanliness, and withdraw any instrument whose insulation is compromised from electrosurgical use. Ultrasonic-clean before autoclaving, and confirm the retention mechanism holds position after reprocessing.
Every pattern is forged from German stainless steel, Class I, reusable, CE-marked, and built under ISO 13485 the documentation a hospital supply team verifies before qualifying a vendor. Warranty is one year with return-and-replacement, MOQ is 1 piece, orders over $99 ship free in carton box packing, and OEM marking is available for distributors.
