Abstract: A lithotriptor is disclosed, which comprises an outer slender tube having an outside diameter small enough to be inserted into the organ growing a stone therein and an inner member disposed inside the outer slender tube. The inner member or the outer slender member incorporates therein an explosive layer or a gas-generating layer, ignition means for igniting the explosive layer or the gas-generating layer, and a closing member for preventing rearward advance of the gas evolved during the explosion of the explosive layer or the gas-generating layer. By the blasting of the explosive layer or the gas-generating layer, the outer slender tube or the inner member is caused to collide with the stone and crush it.

Abstract: PURPOSE:To obtain a lithoclastic agent producible easily, insertable easily in bored hole of a calculus, capable of breaking the calculus by dilation pressure and having high safety, by using a dilation material developing dilation pressure by the hydration reaction with water, ad kneading the agent with an organic solvent. CONSTITUTION:A dilation material developing dilation pressure by the hydration reaction with water (e.g. static disintegration agent, dilation material for cement concrete, quick lime, calcined dolomite, etc.) is kneaded with an organic solvent (e.g. methanol, ethyl ether, acetone, etc.) to obtain a solid lithoclastic agent easily. A lithoclastic agent having high handleability and insertable easily into the bored hole of a calculus can be formed by forming the dilation material in the form of rod, table, etc., using the organic solvent as a binder. Since the dilation pressure develops slowly according to the elapse of time, the calculus can be broken without generating gases and shock wave in contrast with the case using an explosive as a disintegration agent, and accordingly, the agent has excellent safety.

Abstract: PURPOSE:To crush a rock or the like efficiently, easily and safely, by kneading a static crushing agent powder using an org. solvent to form a solid agent, inserting the solid agent into a fill hole, which has been formed in the material to be crushed, in the presence or absence of water and, if the solid agent is inserted in the absence of water, pouring water into the hole. CONSTITUTION:A static crushing agent powder [e.g., Blister (trade name)] is kneaded with an org. solvent to form a solid agent. The solid agent is inserted into a fill hole, which has been formed in a material to be crushed (e.g., rock), in the presence or absence of water. When the solid agent was inserted into the hole in the absence of water, water is poured therein, thereby statically crushing the material by taking advantage or the expansion pressure caused by the crushing agent. Examples of the org. solvent include methanol, ethyl ether, ethylene glycol, acetone, etc. The previous solidification of the static crushing agent according to the present invention not only enables more easy handling of the crushing agent than the conventional method but also can avoid a locally concentrated filling of the crushing agent in a crevice etc.
