Description

Technical Field

[0001] The present 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, which is a plasma resectoscope. The bipolar working device and the resectoscope sheath are sequentially inserted into the resectoscope body. When the bipolar resection ring is inserted into the rubber plug, the interference plug is in close contact with the bipolar resection ring, and under the squeezing of the bipolar resection ring, the interference plug expands outward, but is still tightly connected to the bipolar resection ring, connecting the connecting block to the resectoscope sheath, so that the gap plug is tightly connected to the inner wall of the resectoscope sheath, and there is a gap between the gap plug 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 seal between the bipolar resection ring and the resectoscope sheath, but also ensures the seal between the rubber plug and 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 removed each time, resulting in low surgical efficiency. For patients with larger prostate volumes, the risks associated with increased operation time are increased, and the surgical trauma is greater. Secondly, for most doctors who have mastered the use of plasma resectoscopes, the operating speed of the operating doctors is limited, and the longer operations increase the fatigue of the operating doctors. Moreover, 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, meet the delicate operation of resecting the prostate as much as possible during the operation, and improve surgical safety. Summary of the Invention

[0004] (1) Technical problems solved

[0005] In response to the shortcomings of the existing technology, the present invention provides a continuous cutting plasma resectoscope to solve the problem that the existing technology proposed in the background technology requires repeated manual resection, and only a small part can be removed each time, which limits the operating speed of the doctor.
