Title:
ADJUSTABLE STONE REMOVING STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2022/205531
Kind Code:
A1
Abstract:
The present invention provides an adjustable stone removing structure, comprising a base body, vibration heads, and displacement modules. Vibration recesses adapted to the vibration heads are formed in the base body; the vibration heads comprise a guide head and at least two limiting heads; and the displacement modules are disposed on the base body, and the displacement modules are used for enabling the guide head and the two limiting heads to move inwards to be gathered or move outwards to be away from each other. A limiting and guiding type vibration head structure is used, so that the vibration effect is more directional; the displacement modules can enable the vibration heads to achieve clamping and expansion, kidneys of different sizes can be adapted, adjustment and limiting can be performed according to the kidneys of different sizes, and the requirements of different sizes of kidneys for stone removal are satisfied; and the adjustable stone removing structure has enhanced stone removing efficiency, and is simple in structure, portable, and convenient to use.
