TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field, especially a ureteroscope often used in urological operation. BACKGROUND

[0002] The ureteroscope is a medical equipment for urology treatment, which is used for the diagnosis and treatment of ureteral diseases, greatly improves the diagnosis and treatment level of ureteral diseases, and shortens the hospitalization time of patients. Its principle lies in that the endoscope entering the ureter can clearly observe the lesions in the ureter under direct vision or with the help of a television monitoring system, such as stones, tumors, etc., so as to diagnose and treat ureteral diseases. Many diseases in urology can be treated by using the ureteroscope, for example, ureteroscopic lithotripsy is a kind of pure urological endoscopic minimally invasive surgery which uses a thin mirror with a diameter of about 3mm to insert into the ureter through the urethra and bladder to crush and remove ureteral stones or kidney stones. It uses the natural urinary system cavity of the human body without any incision on the body. It is suitable for various ureteral stones and part of kidney stones which are ineffective for conservative treatment. At present, the ureteroscope is widely used, and the existing ureteroscope has poor sealing performance, which increases the difficulty of operation and reduces the efficiency of operation, so a better scheme is needed to improve the existing ureteroscope.

[0005] The magnetic sheet type instrument channel component includes a lens barrel, a lens compression cap, a lens sealing seat, a lens rear seat, and a horn-shaped instrument guide slot. The lens barrel is inserted into the lens sealing seat. The outer end of the lens sealing seat is surrounded by a magnetic steel. The lens sealing seat is inserted into the lens compression cap. The rear end of the lens compression cap is threadedly connected to the lens rear seat. The lens barrel and the magnetic steel are located in the lens rear seat. The lens rear seat is snap-connected to the horn-shaped instrument guide slot. The lens barrel and the mirror tube are on the same axis.

[0006] The magnetic steel has a four-petal structure. The two petals at the upper end are magnetic steel one, and the two petals at the lower end are magnetic steel two. The rear end of the magnetic steel is provided with a magnetic steel gasket.

[0007] The front end of the mirror cap is connected to the mirror tube, and a mirror sealing ring is provided around the connection.

[0008] The lens tube between the light source connector and the interface mirror is provided with holding grooves on both sides, which are elliptical grooves.

[0009] The beneficial effects of this utility model are as follows: After the surgical instruments are removed, the magnet and the magnetic pad automatically seal the instrument, reducing liquid leakage and contamination of the interface mirror, and enhancing the sealing performance. Water outlet valves and water inlet valves are provided on both sides, making it more convenient to clean the inside. An auxiliary channel is also provided at the lower end of the instrument channel to improve surgical efficiency and reduce surgical difficulty. Attached Figure Description
