Problems solved by technology

[0002] Calculus is a solid block formed in the catheter lumen or lumen of the luminal organ in the human or animal body. When treating patients, the stones in the catheter lumen are crushed by ultrasound and then discharged from the body. Traditionally, when performing stone removal, the vibrator is used to physically vibrate the patient outside the patient's body to assist the patient in removing stones. However, the vibration process has no directionality, and the amplitude is small and the frequency is high. However, the human skin itself is elastic, so the vibration process is easy to interact with the human body. The vibration of the skin forms a resonance, which resolves the vibration effect and cannot assist the patient in stone removal

Abstract

The invention discloses a hydraulic directional stone discharging machine, and relates to the technical field of medical instruments. The hydraulic directional stone discharging machine comprises: a shell; an elastic liquid bag fixedly mounted in the tray; a liquid bag communicated with the shell through a one-way valve; a handle arranged on the outer wall of the shell; a runner pipe arranged in the handle; an electromagnetic valve mounted in the runner pipe; a piston hermetically and slidably mounted on the inner wall of the shell between the limiting rings; a firing pin fixedly mounted on the outer wall of the piston; and a driving mechanism mounted in the shell, wherein the driving mechanism drives the traction mechanism through an electronic clutch, and the traction mechanism is connected and matched with the firing pin. The hydraulic directional stone discharging machine has the advantages that when the driving mechanism drives the firing pin to collide with the shell, and the patient is vibrated through the nursing pad to remove urinary calculus, the vibration direction is adjusted by adjusting the collision direction of the firing pin, and the vibration amplitude is adjusted by adjusting the collision strength of the firing pin by adjusting the compression length of the reset spring; and the vibration frequency is adjusted by adjusting the impact interval of the firing pin, so that the use is more flexible, and the stone discharging effect is improved.

Description

technical field [0001] The present invention relates to the technical field of medical devices. Background technique [0002] Stones are solid lumps formed in the lumen of catheters or in the lumen of luminal organs in humans or animals. When treating patients, the stones in the catheter lumen are broken up by ultrasound and then excreted. Traditionally, when expelling stones, the vibrator is used to physically vibrate the patient in vitro to assist the patient in expelling stones. However, the vibration process has no directionality, and the amplitude is small and the frequency is high. The human skin itself is elastic, so the vibration process is easy to be compared with the human body. The vibration of the skin forms a resonance, so that the vibration effect is resolved and the patient cannot be assisted in stone removal. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a hydraulic directional stone discharger ...
