Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, and in particular to a push-type stone removal device for stones in the renal pelvis and renal calyx. Background Art
[0002] Kidney stones are stones that occur in the renal calyx, renal pelvis, and the connection between the renal pelvis and the ureter. Clinically, renal cast stones, multiple stones, and calyx stones are refractory kidney stones. Extracorporeal shock wave lithotripsy (ESWL) has little effect on such stones and has many complications. Open surgery may cause renal parenchymal lacerations, massive renal bleeding, and even kidney removal. Due to the special structure of the kidney and the special environment of the calyx where the stones are located during lithotripsy, the space inside the calyx is small, and it is difficult for general lithotripsy instruments to reach the calyx, resulting in troublesome stone removal in the calyx. Even if the lithotripsy machine enters the calyx, during the lithotripsy process, stone fragments are easy to enter the calyx, resulting in residual stones, incomplete surgery, and poor treatment effect. To this end, we propose a push-type stone removal device for stones in the renal pelvis and calyx. Utility Model Content

The tube wall of the puncture tube is equipped with a grip, and a group of symmetrical vertical plates are fixedly installed on the tube wall of the puncture tube. A handle is movably connected between the vertical plates through anchor bolts, and the outer wall of the handle is connected to the circle wall of the wire ferrule through a wire drawing, and the wire drawing runs through the puncture tube, and a limit block is installed at the bottom of the wire ferrule, and the outer wall of the grip is connected to the outer wall of the handle through a spring rod.
[0005] By adopting the above technical scheme, when removing stones, since a material removal mechanism is installed on the wall of the puncture tube, and the material removal mechanism is composed of a grip, a spring rod, a handle, a wire, a limit block, a wire ferrule and a vertical plate, after the medical staff inserts the puncture tube into the kidney, the wire ferrule is wrapped around the outer wall of the stone. Since a group of symmetrical vertical plates are installed on the wall of the puncture tube, a handle is movably connected between the vertical plates by anchor bolts, so that the handle can rotate between the vertical plates. Since the outer wall of the handle is connected to the circle wall of the wire ferrule by the wire, and the wire runs through the puncture tube, the grip and the handle are connected by the spring rod. Therefore, after the medical staff holds the grip, the handle rotates between the vertical plates, and the handle stretches the wire, so that the wire pulls the wire ferrule. Therefore, after the wire ferrule is pulled, the wire ferrule contracts to clamp the stone. The staff pulls the puncture tube to facilitate the removal of the stone.
[0006] Specifically, it also includes a speculum mechanism, and the speculum mechanism is installed on the tube wall of the puncture tube.
[0007] By adopting the above technical solution, kidney stones can be observed through the endoscope mechanism.
[0008] Specifically, the endoscope mechanism is composed of a percutaneous nephroscope shell, a endoscope head and a lighting lamp. A percutaneous nephroscope shell for viewing is installed on the tube wall of the puncture tube. A endoscope head is installed on the tube wall of the percutaneous nephroscope shell. A lighting lamp is installed at one end of the percutaneous nephroscope shell.
[0009] By adopting the above technical scheme, when observing kidney stones, since a endoscope mechanism is installed on the tube wall of the puncture tube, and the endoscope mechanism is composed of a percutaneous nephroscope tube shell, a endoscope lens and a lighting lamp, since a percutaneous nephroscope tube shell is installed on the tube wall of the puncture tube, after the percutaneous nephroscope tube shell is inserted into the kidney, since a endoscope lens is installed on the tube shell of the percutaneous nephroscope tube shell, a person observes the percutaneous nephroscope tube shell through the endoscope lens, observes the kidney through the refraction of light in the percutaneous nephroscope tube shell, and then illuminates the kidney through the lighting lamp, so as to find the stones in the kidney.
[0010] Specifically, a joint shell is installed on the tube wall of the puncture tube.
[0011] By adopting the above technical solution, it is possible to connect to an external gas source through the joint shell.
[0012] Specifically, a controller for controlling the lighting lamp is installed on the shell wall of the joint shell.
[0013] By adopting the above technical solution, the lighting lamp can be conveniently controlled through the controller.

After the medical staff inserts the puncture tube into the kidney, the wire ferrule is wrapped around the outer wall of the stone. Since a group of symmetrical vertical plates are installed on the wall of the puncture tube, a handle is movably connected between the vertical plates by anchor bolts, so that the handle can rotate between the vertical plates. Since the outer wall of the handle is connected to the wall of the wire ferrule by the wire, and the wire passes through the puncture tube, the grip and the handle are connected by the spring rod. Therefore, after the medical staff grips the grip, the handle rotates between the vertical plates, and the handle stretches the wire, so that the wire pulls the wire ferrule. After the wire ferrule is pulled, the wire ferrule contracts to clamp the stone. The staff pulls the puncture tube to facilitate the removal of the stone.
