Endoscope and electric resection all-in-one device for urinary system

Abstract

The invention relates to an endoscope and electric resection all-in-one device for the urinary system. The endoscope and electric resection all-in-one device for the urinary system comprises a light source, a light transmitting optical fiber channel, an imaging optical fiber channel, an electric resection electrode channel, an image transmitting optical fiber and an image display device. The light transmitting optical fiber channel, the imaging optical fiber channel and the electric resection electrode channel are all arranged in sheaths. The sheaths comprise the sheath I and the sheath II which are hinged to each other. Two sliding grooves which are arranged axially are symmetrically formed in the outer wall of the sheath I. An endoscope further comprises a swinging driving device. The swinging driving device is used for controlling the sheath II 4 to swing at the far end. According to the endoscope and electric resection all-in-one device for the urinary system, bending to different degrees can be conducted according to needs, the defect of an existing bladder resectoscope is overcome, the application range of the bladder resectoscope is remarkably broadened, the recurrence rate of bladder tumors is lowered, the pain of a patient is relieved, and the burden of the patient is lightened.

Description

Technical field [0001] The invention involves the field of medical equipment technology, which specifically involves an endoscopic electrical cutting device for urinary systems. Background technique [0002] Clinically, bladder tumors are common diseases in the urinary system, and the first place in urinary tumors. The main treatment method is surgical treatment, combined with postoperative bladder irrigation chemotherapy.Its main surgical method is the scaling of the bladder tumor on the pubic bone (ie TURBT).Due to the high recurrence rate of bladder tumors, it is often necessary to surgery or multiple surgical treatment again, and the trauma of open surgery is large. The postoperative recovery is slow, the repetitiveness can be poor, and it has gradually been eliminated.Therefore, the trauma (TURBT) of the urethral bladder tumor (Turbt) has a small trauma, recovered after surgery, and has strong recurrence. It has gradually replaced open surgery.However, because the existing b...

Problems solved by technology

However, due to the fact that the existing cystoscope is straight and rigid and cannot be bent, it becomes a blind spot for tumors and lesions near the anterior and lateral walls of the bladder and near the internal opening of the urethra, and it is easy to miss diagnosis. Due to the limitations of cystoscopy, it is difficult to treat with electric resection, and open surgery is often required, which increases the patient's trauma and the risk of surgery
