A minimally invasive lithotripsy device; for fragmenting calculi stones formed in the body (such as in the kidney, urethra, gall bladder and salivary glands) by means of vibrations and performing the cracking operation within the body; for rupturing foreign objects with the aim of curing cancerous cells and tumours; for treating fractured and broken bones and hence easing the pain caused by such reasons. The lithotripsy device serves to break the targeted mass/stone by a nail, according to which method a hammer, that moves by means of pressurised air, applies systematic strikes on the nail. The device acquires a mechanism which serves to release the air, in front of the hammer as it moves forward, and at the back of the hammer as it is reset backwards, out to the atmosphere while it incorporates a handling equipment. |
