Description

Technical Field

[0001] The invention relates to the technical field of plasma resectoscopes, and in particular to a continuous cutting plasma resectoscope. Background Art

[0002] The plasma resectoscope is the most effective treatment for electroresection of prostate and bladder tumors. The patent publication number is CN117653315A. A plasma resectoscope has a bipolar working device and a resectoscope sheath sequentially inserted on the resectoscope body. When the bipolar resection ring is inserted into the rubber plug, the interference plug body is in close contact with the bipolar resection ring, and under the squeezing of the bipolar resection ring, the interference plug body expands, but is still tightly connected to the bipolar resection ring, connecting the connecting block to the resectoscope sheath, so that the gap plug body is tightly connected to the inner wall of the resectoscope sheath, and there is a gap between the gap plug body and the bipolar resection ring, which will not affect the subsequent movement of the bipolar resection ring. The segmented setting of the rubber plug not only ensures the sealing between the bipolar resection ring, but also ensures the sealing between the resectoscope sheath, so that sterile water will not flow out from the gap, thereby achieving the internal sealing of the ion resectoscope and the reciprocating motion of the bipolar resection ring.

[0003] However, the above-mentioned existing technical solutions require repeated manual resections, and only a small part can be resected each time, resulting in low surgical efficiency. For patients with larger prostate volumes, the risks associated with increased operation time and greater surgical trauma are caused. Secondly, for most doctors who have mastered the use of plasma resectoscopes, the operating speed of the operating doctors is limited, and longer operations increase the fatigue of the operating doctors. In addition, the current plasma resectoscope's resection ring can only resect the prostate in the anterior-posterior direction during TURP, and it is impossible to select the most appropriate cutting angle for operation according to surgical needs, so as to meet the delicate operation of resecting the prostate as much as possible during surgery and improve surgical safety.
