Embodiment 1

[0034] Transurethral ureteral rigid convection negative pressure channel lithotripsy device, including a rigid ureteroscope 1 and a negative pressure suction tube 2, the negative pressure suction tube 2 is installed at one end of the rigid ureteroscope 1, and the negative pressure suction tube 2 is away from the end of the rigid ureteroscope 1 Two curved splints 3 are slidably connected on the outside, and two first slide grooves 4 are provided inside the rigid ureteroscope 1 and the negative pressure suction tube 2. The extruding mechanism that separates the two arc-shaped splints 3 from each other when extruding the arc-shaped splints 3 .

[0035] The interior of the arc splint 3 is provided with a plurality of third chute 8 and fourth chute 13, and the plurality of third chute 8 is connected with the corresponding fourth chute 13, and the inside of the third chute 8 is slidingly connected Extrusion bar 9 is arranged, the inside of the third chute 8 is provided with second elas

Embodiment 2

[0038] The device for removing stones through the urethral ureteral rigid convection negative pressure channel, on the basis of Embodiment 1, the extrusion mechanism includes a moving plate 11 that is slidably connected to the inside of the first chute 4, and one side of the moving plate 11 is fixed with a Extrude the first extruding plate 12 of the arc splint 3, the arc splint 3 is located on both sides of the first chute 4, and the side plates 6 are fixed on both sides. A first spring member 7, it should be noted that, the first spring member 7 can use devices such as springs.

[0039] Wherein, the clamping mechanism includes a plurality of the fifth chute 17 opened on the inner wall of the arc splint 3, the inside of the fifth chute 17 is slidably connected with a cylindrical rod 18, and the side of the cylindrical rod 18 close to the inside of the negative pressure suction pipe 2 is fixed with a The clamping plate 20 is fixed with a second pressure receiving plate 21 on the s

Abstract

The invention discloses a transurethral ureter hard convection negative pressure channel lithotripsy and lithotripsy device which comprises a ureter hard mirror and a negative pressure suction pipe, two arc-shaped clamping plates are slidably connected to the outer side of the end, away from the ureter hard mirror, of the negative pressure suction pipe, and two first sliding grooves are formed in the ureter hard mirror and the negative pressure suction pipe correspondingly; and an extrusion mechanism used for extruding the arc-shaped clamping plates and enabling the two arc-shaped clamping plates to be far away from each other when the arc-shaped clamping plates are extruded is arranged in the first sliding groove. When large broken stone is encountered, the moving plate is pushed to drive the first extrusion plate to move in the first sliding groove, when the first extrusion plate extrudes the arc-shaped clamping plates, the arc-shaped clamping plates move in a second sliding groove, the two arc-shaped clamping plates are far away from each other, and when the distance between the two arc-shaped clamping plates is increased, boken stones can be accommodated in the device, so that the urethra is prevented from being hurt by larger broken stones or sharp parts of the broken stones.
