Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to an endoscope guide nozzle. Background Art

[0002] During percutaneous renal surgery and ureteroscopic surgery, therapeutic instruments (such as laser optical fiber, balloon dilatation catheter, lithotripsy basket, occluder, guidewire, etc.) are generally inserted from the working channel of the endoscope. In order to maintain a clear field of vision during the operation, continuous infusion of flushing fluid, such as saline, is often required. When the hydraulic pressure in the inner cavity of the endoscope is too high, flushing fluid and blood may be ejected from the therapeutic instrument insertion port at the rear end of the endoscope onto the operator. Therefore, in order to prevent the liquid from flowing back out of the body through the operating channel, a waterproof cap needs to be installed on the operating hole.

[0003] like Figure 1 As shown, Figure 1 This is a common structure of the waterproof cap 2, including an interface end 201, a sealing end 202 and an annular groove 203. It is generally made of elastic materials such as silicone. In order to prevent liquid backflow, a zero-gap structure is generally used, which makes it difficult for therapeutic instruments to enter the endoscope. Therefore, clinicians will install a guide nozzle on the waterproof cap to expand the waterproof cap and facilitate the entry of therapeutic instruments into the endoscope; after the instrument reaches the target position, the guide nozzle is removed from the waterproof cap.

[0004] The Chinese utility model patent with publication number CN208837882U discloses an endoscope waterproof cap, including an elastic cap with good sealing properties, which can not only ensure that there will be no water leakage during endoscopic surgery, but also can temporarily expand the waterproof cap through an expansion guide, thereby providing a temporary endoscopic working channel, which is convenient for other medical devices to be implanted into the endoscope. However, after the above-mentioned expansion guide guides the treatment instruments such as balloon dilation catheters, guide wires, and stone baskets into the endoscope, the expansion guide is suspended on the treatment instrument, which causes great inconvenience to clinicians and affects the surgical operation. If the expansion guide is to be removed from the treatment instrument, the operating end of the treatment instrument left outside the human body can only be disassembled, and then the expansion guide can be slid to the end along the length direction of the treatment instrument before it can be detached from the treatment instrument, which is a cumbersome step.

[0005] How to solve the above problems has become a technical problem that needs to be solved urgently. Utility Model Content
