Description

TECHNICAL FIELD

[0001] The present application relates to the field of medical equipment, in particular to a medical shock wave lithotriptor machine bed structure and a matching shock wave lithotriptor. BACKGROUND

[0002] The shock wave lithotriptor, also known as extracorporeal shock wave lithotriptor, is an important device for non-invasive crushing of kidney stones in patients. The shock wave lithotriptor generates high-energy shock waves outside the body, accurately locates the stone position by using an ultrasonic and X-ray positioning system, and then focuses the shock wave on the stone to break it into small particles, which are eventually discharged from the body through urine.

[0003] Among them, most of the shock wave lithotriptors contain a machine bed, and the shock wave lithotripsy process often lasts nearly 1 hour. The quality of the machine bed often plays a crucial role in the effect of shock wave lithotripsy. The existing shock wave lithotriptor machine bed often has a single structure and is not much different from a general operating bed, with at most angle adjustment and movement functions to cooperate with positioning. However, during the shock wave lithotripsy process, the patient's respiratory control is often a key factor in the success of the stone crushing. In a tense situation, the patient often involuntarily takes a deep breath, but the amplitude of the deep breath is large, which can cause the patient's kidney to shift, thereby greatly affecting the stone crushing effect. The existing shock wave lithotriptor machine bed does not optimize this aspect. SUMMARY
