Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a movable water-blocking drainage device on a ureteroscope. Background Art

[0002] Percutaneous nephrolithotomy (PCNL) is an important part of endourological surgery. In the treatment of upper urinary tract stones, it has become the main modern treatment method together with ureteroscopy and extracorporeal shock wave lithotripsy, and has completely changed the surgical treatment of traditional open surgery. Through comprehensive treatment methods such as percutaneous nephrolithotomy, ureteroscopy and extracorporeal shock wave lithotripsy, more than 90% of kidney stones can be exempted from open surgery.

[0003] During PCNL, when using a ureteroscope, continuous high-flow infusion of normal saline is required to expose the surgical field and drain the drainage fluid output from the kidney into a collector.

[0004] At present, the drainage method mainly uses gauze wrapped around the scope to achieve drainage. However, this method has a defect - the drainage fluid overflows when the scope enters and exits the incision: as the scope enters and exits the incision, the gauze drainage cannot effectively prevent the overflow of the drainage fluid, causing the floor of the operating room to be wet, affecting the surgical environment, and even causing a "flooding" phenomenon, posing a safety hazard. Summary of the invention

[0005] The present invention is intended to provide a movable water-blocking drain on a ureteroscope to solve the problem in the prior art that gauze is usually used to wrap the drainage when discharging drainage fluid from the ureteroscope, which cannot effectively prevent the overflow of the drainage fluid, thus hindering the operation.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] The basic technical solution provided by the present invention is: a movable water-blocking drainage device on a ureteroscope, comprising a shell, the shell consisting of an upper connecting part and a lower connecting part, the upper connecting part and the lower connecting part both consisting of a water retaining part, a buffer part and a mounting part, two groups of the mounting parts are rotatably connected by hinges, the two groups of the mounting parts are fixedly connected with a pressure plate, an elastic sheet is arranged between the two groups of the pressure plates, and the lower connecting part is connected with a liquid guide tube.

[0008] Principle of the basic technical solution: The ureteroscope body is cylindrical in shape. The elastic force of the elastic sheet 1 causes the pressure plates to move away from each other until the upper connecting part and the lower connecting part are symmetrically covered on the upper and lower sides of the ureteroscope body respectively, and the connection between the two is tightly fitted, the inner side of the mounting part fits with the surface of the body, and the shell is fixed to the body through the mounting part. The drainage fluid on the surface of the body is blocked by the shell, and is discharged after passing through the water retaining part, the buffer part, the water storage part, the liquid outlet and the catheter in sequence; the two groups of pressure plates are pressed by fingers to bring them closer to each other, causing the connection points of the two groups of mounting parts to move away from each other, so that the mounting part is separated from the body. When the opening reaches a certain degree, the device can be removed from the body or moved.

[0009] The beneficial effects of the basic technical solution are: the water retaining part is in the shape of a trumpet that opens outward, which effectively blocks the splashing of the drainage fluid; the buffer part is a spherical space inside; and the design of the water storage part is conducive to the timely discharge of water in the buffer part, thereby effectively preventing the problem of drainage fluid backflow, that is, the drainage fluid can be discharged into a designated container through the catheter, thereby solving the problem that the prior art usually uses gauze to wrap the drainage when discharging the drainage fluid from the ureteroscope, which cannot effectively prevent the overflow of the drainage fluid, thereby being detrimental to the progress of the operation.

[0010] Preferably, the lower connecting portion is connected to a water storage portion, the water storage portion is connected to a liquid outlet, the liquid guide tube is detachably connected to the liquid outlet, and the liquid outlet is connected to a valve.

[0011] With the above arrangement, when the liquid container needs to be replaced, the liquid outlet passage of the liquid outlet can be closed by the valve to prevent the drainage liquid from being discharged at will.

[0012] Preferably, the catheter is a plastic telescopic tube.

[0013] Through the above settings, it has better adaptability to different discharge distances / positions.

[0014] Preferably, the lower connecting part is connected to an adjusting seat, the adjusting seat is rollingly connected to an adjusting ball, the connecting surface between the adjusting ball and the adjusting seat is a rough surface, the adjusting ball is fixedly connected to an adjusting sleeve, the adjusting sleeve is slidably connected to an adjusting rod, the adjusting sleeve is provided with a threaded hole, the threaded hole is threadedly connected to a fastener, the fastener is clamped with the adjusting rod, the adjusting rod is connected to a sliding sleeve via a connecting rod, and the sliding sleeve is slidably connected to the liquid guide tube.

[0015] Through the above arrangement, when the catheter is stretched to a certain length, the adjusting rod is loosened by screwing the fastener, and the adjusting rod is slid downward to make the sliding sleeve slide to a position close to the end of the catheter, and then the fastener is screwed in the opposite direction to fix the adjusting rod, so that the catheter is in a stable state. When the discharge angle / position of the catheter needs to be adjusted, the adjusting ball and the adjusting seat are cooperated to pull the adjusting rod to change its angle, thereby driving the catheter to move through the slide groove, thereby achieving the effect of adjusting the discharge angle / position of the catheter.

[0016] Preferably, the outer diameter of the liquid guiding tube is larger than the inner diameter of the liquid outlet.

[0017] Through the above arrangement, the interference fit is conducive to reducing the probability of the liquid guide tube being separated from the liquid outlet, while improving the sealing between the two, and the reliability is relatively high.

[0018] Preferably, a rubber pad is fixedly connected to the inner side of the mounting portion.

[0019] The provision of the rubber pad is helpful to improve the sealing performance of the mounting part connection. At the same time, it is located between the mounting part and the mirror body to prevent contact between the two, thereby providing protection for the mirror body. BRIEF DESCRIPTION OF THE DRAWINGS
