Urology instruments cover two distinct jobs, traction on the prostate during prostatectomy, and calibration or dilation of the urethra for catheterization. Peak Surgicals supplies five patterns, Lowsley Tractor, Wire Mandrins, catheters, Otis Bougie and Walther Dilator, in German stainless steel, from $6.60 to $541.55. Each is CE marked and built under ISO 13485. Compare all five instruments in the grid below.
Prostate Traction, Wire Mandrins and Urethral Access
The Lowsley Prostatic Tractor applies traction to the prostate gland during prostatectomy through jaws opened and closed by a handle knob, wire mandrins stiffen a flexible catheter for controlled insertion, and Otis Bougie a Boule and Walther Dilator Catheter calibrate or dilate the urethra, each instrument answers a different step in urethral access and prostate surgery. Function, not shared anatomy, is what groups this range.
Lowsley Prostatic Tractor (PS-OT-0974, $541.55) carries straight and curved variant ends (PS-1422, PS-1423), with jaws that grip the prostate for traction, rounded tips allow comfortable perineal introduction. Wire Mandrins (PS-1401, PS-1402, from $6.60) insert into a flexible catheter to add rigidity during placement, then withdraw once the catheter is positioned. Female Catheters for 5" and 8" Urethral Catheterization (PS-1409, $11.00) cover routine catheterization at two lengths. Otis Bougie a Boule (PS-1404, $14.30) calibrates the urethra from 8Fr to 40Fr with a bulbed tip designed for progressive dilation. Walther Dilator Catheter (PS-1408A, $7.15, 5¼") provides urethral access and dilation at a shorter working length. We supply every pattern at MOQ 1.
French Gauge Sizing and Why It Matters
Urethral instruments are sized in French gauge (Fr), where each unit equals roughly ⅓mm of diameter, a system distinct from the millimetre or inch measurements used elsewhere in this catalogue. The Otis Bougie's 8Fr to 40Fr range covers calibration from a narrow stricture assessment through to full urethral capacity, and selecting the wrong size either fails to dilate adequately or forces tissue beyond what the urethra safely tolerates.
Progressive dilation is the working principle behind a bougie: rather than forcing a single large instrument through a narrowed urethra, the operator works through successive sizes, each slightly larger, letting tissue accommodate gradually. The bulbed tip on the Otis pattern is shaped specifically to lead that progression without catching against the urethral wall. Selecting the correct starting Fr size against the patient's baseline urethral calibre, and stepping up rather than skipping sizes, is what makes progressive dilation safe.
Reprocessing, Material and Certification
These instruments are forged from German stainless steel, corrosion-resistant across repeated autoclave cycles, and holding the smooth, polished surface finish that a urethral instrument depends on. Surface finish is the inspection point unique to this category: any burr, pit or roughness on an instrument passed through the urethra risks mucosal trauma, so inspect the full working length rather than only the tip before each use. The Lowsley Tractor's jaw mechanism should be checked for smooth opening and closing under the handle knob.
Every instrument is 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.
