Electrosurgical instruments deliver radiofrequency current to coagulate tissue and control bleeding bipolar patterns confining that current between two tips, monopolar patterns returning it through a patient plate. Peak Surgicals supplies 71 patterns across bipolar forceps, monopolar forceps, ESU pencils, diathermy electrodes and bipolar scissors, from $3.96 to $495.00, every one carrying a model number. Each is CE marked and built under ISO 13485. Compare all 71 patterns in the grid below.
Bipolar or Monopolar: Which Instrument for Which Field?
Bipolar forceps confine current between the two tips, limiting lateral thermal spread for work near nerve, vessel or delicate tissue, while monopolar instruments pass current through the patient to a return electrode, cutting and coagulating faster across open fields. The choice is a thermal-margin decision before it is a preference.
Bipolar patterns dominate where collateral damage matters. Jeweller Bipolar Forceps (PS-1039, $25.30) and McPherson Bipolar Forceps (PS-1042, $25.85) carry the finest tips for microsurgical coagulation; Adson Bipolar Forceps (PS-1713, $27.50) handle general tissue; Cushing (PS-1109, from $22.00) and Yasargil Bayonet (PS-1094A, $39.60) reach deep neurosurgical fields. For open work, monopolar patterns move faster, Adson Monopolar Forceps (PS-1063, from $40.15), Gillies (PS-1058-1, from $25.30) and Gerald 1×2 Teeth (PS-1065-1, from $40.15) all deliver cut-and-coagulate through one tip.

Non-Stick, Irrigating and Bayonet: What Each Solves
Three engineering answers to three specific failures. Eschar buildup on the tips is the first: coagulated tissue welds to steel, and pulling the forceps away tears the clot it just made. Non-stick tips resist that adhesion, Straight Bipolar Forceps Non-Stick (PS-1085, $39.60), Cushing Non-Stick (PS-1088, $55.00) and McPherson Two Pin (PS-1091, $34.65) with 0.5–2mm tips carry it.
Heat is the second. Irrigating patterns run saline down the shaft to cool the tips at the moment of coagulation, which both prevents sticking and limits thermal spread. European Irrigation Bipolar Forceps (PS-1046, $50.60) deliver 0.3–2mm irrigating tips; Hardy Bayonet Irrigation 10" (PS-1050, $38.50) and Cushing Irrigation 7.5" (PS-1048, $33.00) reach deep fields. Sightline is the third — the bayonet step moves the shank laterally so the hand never blocks the view down a narrow corridor, which is why Jansen (PS-1089, $31.90), Scoville (PS-1094, $38.50) and Malis patterns all use it. See irrigation and non-stick ranges.
Reusable, Single-Use, Electrodes and Certification
Reusable patterns in German stainless steel carry the lower cost per procedure where reprocessing capacity exists; single-use patterns remove that burden entirely at $22.00 each across Adson, Iris, Jansen, Jeweller, Malis, McPherson, Scoville and Semkin. Electrode accessories complete the monopolar side, ESU pencils from $3.96, Monel Handle (PS-MH-00312, $16.50), Monel Blade Fully Insulated (PS-MBFI-00311, $27.50) and Diathermy Arm With Ball Curved (PS-DAWBC-00310, $38.50) at 15mm.
Insulation integrity is the reprocessing point that matters most on these instruments: a breached coating routes current where it was never intended, so inspect insulation each cycle and ultrasonic-clean tips before autoclaving. Every pattern is CE marked and built under ISO 13485. Warranty is one year, MOQ is 1 piece, orders over $99 ship free in carton box packing, and OEM marking is available.
