０mg入りの衝撃波発生具３，３Ａで衝撃波を１７０回か
ら２３０回発生させることにより、体外に自然排出可能
な大きさまでに破砕しうることが確認された。So, actually, using a reflective focusing mirror 1 having a diameter of 13 cm and a depth of 11 cm with the first focus at 2.14 cm from the bottom, a 1 cm × 1.5 cm × 2 cm renal stone crushing experiment was performed in water. , Lead azide 1 of Examples 1 and 2 in FIGS. 2 and 3
It was confirmed that by generating shock waves 170 to 230 times with shock wave generators 3 and 3A containing 0 mg, they can be crushed to a size that can be naturally discharged to the outside of the body.

られた。In order to crush a calculus from outside the body with the reflection focusing mirror 1, it is preferable to repeatedly generate a weak shock wave to crush the calculus because the living tissue must not be damaged.
Conventionally, the pressure corresponding to the position is 400 kg / cm 2 to 13
It was crushed by irradiating it with 100 kg / cm 2 several hundred times, but when using the shock wave generators 3 and 3A of the present invention, it was 4
It has been found that the pressure is from 00 kg / cm 2 to 700 kg / cm 2 .

従来のものより非常に格安に提供できる。The stone position aiming device searches for the position of the stone in the human body, and the shock wave reflecting and focusing mirror irradiates the stone with the shock wave generated by the explosion of the medical shock wave generator, so that the stone inside the human body is accurately crushed from outside the human body. can do. Since a large number of shock waves must be generated to treat calculus fragmentation, shock wave generators must be inexpensive in order to receive this calculus fragmentation treatment at a low cost. The generator was expensive because it contained a high-precision detonator, whereas the shock wave generator of the present invention does not include the detonator, so that the detonator and its assembling work, electrical connection, etc. It can be offered at a much cheaper price than conventional ones because it does not require operation.
医療用衝撃波発生具に起爆装置を内蔵しないので、医療
用衝撃波発生具の取扱における安全度が著しく向上す
る。Since the detonator is not built in the medical shock wave generator, the safety level in handling the medical shock wave generator is significantly improved.

る。Also in terms of calculus crushing operation, since the shock wave generator of the present invention does not have a detonator incorporated therein, operations such as electrical connection are not required and the entire operation is speeded up. Particularly, in a shock wave generator having a plurality of explosive parts, the explosive parts can be continuously exploded, so that there is an advantage that the operation is further simplified and speeded up.
