Description

Technical Field

[0001] The utility model relates to the technical field of plasma resectoscopes, in particular to a plasma resectoscope with no edge and double mirrors. Background Art

[0002] Minimally invasive electrosurgical resection surgery is a minimally invasive surgery that uses an electric knife to remove diseased tissue. It can generally play the role of electric coagulation to stop bleeding. It is often used to relieve the discomfort symptoms caused by diseases such as polyps and myomas. It is relatively less traumatic to the body and usually the recovery after surgery is relatively fast.

[0003] During surgery, the sheath assembly needs to be filled with saline, which places extremely strict demands on its sealing performance. If the sealing structure is not effective, the saline inside the sheath assembly will leak through the gaps, contaminating the external structure of the resectoscope and increasing the difficulty of cleaning the resectoscope after surgery. The leaked saline may also drip into other areas and cause contamination, increasing the risk of infection during surgery. Moreover, it is only compatible with a single lens interface type, which has poor versatility. To this end, we have developed a dual-lens plasma resectoscope with no edge to address these issues.
