A shock wave generation apparatus (10) comprises: a shock wave focusing device (11) which has a concave surface (11a); an optical fiber (12) which is inserted into the shock wave focusing device (11); a tubular catheter (13) which guides the optical fiber; an enclosure (14) which constitutes a space to be filled with liquid at the tip of the optical fiber (12); and the liquid (L) which is filled into the enclosure (14). The shock wave focusing device (11) is configured from a ring-shaped coupling part (16) provided with a central hole (11b), and 16 blade parts (17) curved outward from the edge of the coupling part (16) toward the front and provided elastically to the edge of the coupling part (16), and can be folded by rotating the blade parts (17) with respect to the coupling part (16).

摘要： The purpose of the present invention is to reduce as much as possible projection of ultrasound onto portions other than a treatment site. When a user designates a treatment range on a diagnostic image, a switch (12) selects a transmitter for treatment (16). Ultrasound with intensity for treatment is thereby transmitted from a probe (10) to the inside of an organism. When the treatment operation continues for a prescribed time, a control unit (18) controls the switch (12) to select a transmitter for diagnosis (14). The probe (10) thereby emits an ultrasound beam for diagnosis, senses an echo thereof, generates a diagnostic image, and carries out an inspection of a positional shift of the site to be treated. In the inspection, the control unit (18) compares the diagnostic image with a reference image (i.e., a diagnostic image taken when the treatment range is specified or when an immediately previous inspection was carried out), and if a significant difference is detected therebetween, determines that a shift has occurred, issues an alarm, and urges the user to correct the positional shift. It is possible to resume the treatment when the positional shift has been corrected.

摘要： Provided are an optical fiber which has good laser beam condensation efficiency and is highly resilient, and a shockwave generating device employing same. An optical fiber (11) is employed in an underwater shockwave generating device (10) which projects a laser beam underwater and generates an underwater shockwave. The optical fiber (11) comprises: a main body part (16); and a laser convergence part (17) which is disposed upon a leading end thereof. The laser convergence part (17) is configured so as to exhibit an approximately frustum shape wherein the diameter of the leading end (18a) is narrower than the diameter of the base end (18b), and such that an interior angle θ with respect to a radial direction of a lateral face of an axial cross-section gradually decreases toward the front thereof.

摘要翻译：本发明的目的是尽可能多地将超声波投影到治疗部位以外的部位。当用户在诊断图像上指定治疗范围时，开关（12）选择用于治疗的发射器（16）。因此，用于治疗的强度的超声波从探针（10）传播到生物体的内部。当治疗操作持续规定时间时，控制单元（18）控制开关（12）选择用于诊断的发射器（14）。因此，探针（10）发射用于诊断的超声波束，感测其回波，产生诊断图像，并对待处理部位的位置偏移进行检查。在检查中，控制单元（18）将诊断图像与参考图像进行比较（即，当指定了处理范围时或者当执行了之前的检查时所拍摄的诊断图像），并且如果在其间检测到显着差异确定发生了移位，发出报警，并敦促用户纠正位置偏移。当位置偏移被校正时，可以恢复处理。
