A resectoscope is an endoscopic electrosurgical instrument used for minimally invasive procedures in urology and gynaecology without external incisions. Using transurethral access, the surgeon performs tissue resection, vessel coagulation or the removal of pathological lesions under continuous visual control. The modern Olympus resectoscope enables high-precision work and minimises risks to the patient thanks to bipolar technology. Choosing the right equipment affects not only the surgeon’s comfort during the procedure, but also the safety of the operation, the availability of after-sales service, compatibility with power sources, and the reliability of the supply of consumables for day-to-day clinical practice.
What is a resectoscope and how does it work?
A resectoscope is a specialised endoscopic instrument for transurethral resection of tissue and endoscopic operations in hollow organs. It is most commonly used in urology during TUR procedures and in gynaecology for hysteroresectoscopy. The primary purpose of a resectoscope is to remove pathological tissue whilst simultaneously coagulating blood vessels without the need for open surgical access.
To understand how a resectoscope works, it is worth examining its main components:
- a telescope with an optical system for visualising the surgical field;
- a working element with a loop or electrode;
- a tube through which the instrument is inserted into the anatomical cavity;
- an irrigation system for supplying and draining fluid;
- connectors for connection to a high-frequency generator.
The principle of operation is based on the use of high-frequency current. The surgeon performs tissue resection using a loop electrode, whilst coagulation helps to control bleeding without the need for open surgery. The transurethral resectoscope is inserted via natural anatomical pathways, thereby avoiding incisions, reducing the length of hospital stay and speeding up the patient’s recovery.
Modern Olympus systems provide stable visualisation, ergonomic design for the surgeon and compatibility with bipolar technologies, which are now considered the clinical standard in many types of endoscopic surgery.
