Description

A collection of metal instruments which appear to be Endoscopic Operating Sheaths, Trocar Punctures, and Cannula Systems, likely used for Urological or Gynecological endoscopy (such as Cystoscopy, Hysteroscopy, or Resectoscopy). These systems are designed to introduce fluid (for irrigation and visualization) and working instruments into a body cavity.

• Sheaths/Cannulas: The main cylindrical components are sheaths or cannulas. They provide a conduit for the insertion of endoscopes (rigid telescopes) and surgical instruments. They feature stopcocks/valves (the small horizontal levers) to control the flow of irrigating fluid.

• Obturators/Punctures: The pointed, solid rods (one with a very sharp tip) are obturators or trocar punctures. These are inserted into the sheath/cannula to create a safe, blunt, or sharp pathway into the body cavity before the working instrument or endoscope is introduced.

• Resectoscope Bridge/Accessory: The component on the far right, with multiple access ports, is likely a Resectoscope Bridge or working element, which allows for the insertion of instruments (like electrodes) and continuous irrigation flow during procedures like a $\text{TURP}$ (Transurethral Resection of the Prostate).
