Abstract

An external ring-shaped shock wave generator for fracturing a bone in order to increase the body height of adult is composed of shock wave generator, automatic detecting locator, controller and machine frame. An electronic focusing sound heal is only used for both therapy and location.

Description

A kind of extracorporeal shock wave ring-type device for cracking bones

[one] technical field: a kind of extracorporeal shock wave ring-type device for cracking bones, being mainly used in adult's noinvasive does not have huge pain and increases, and belongs to health care or medical apparatus and instruments.

[two] background technology: existing adult's osteotomy increases technology (method is to extend 0.5-1mm every day with securing elongated device after the first osteotomy to see 99.6.5 " Youth Newspaper " P14) owing to start osteotomy, therefore painful risk height greatly.Associate extracoporeal shock wave lithotripsy at this problem, key is that calculus has identical inner characteristic (seeing Yu Yaoting chief editor " biologic applications material " P120) with bone, therefore splits bone and is out of question.Further problem is the osteoblast that can not hinder osteolith tool osteogenesis function on every side, proposes two kinds of schemes for this reason: the one, split bone with audiofrequency hydraulic; The one, use the batch (-type) ultrasound wave, because being flowed by tissue diffusion and blood flow, heat energy exchanges away (" ultrasound medicine " P1504 that sees the Zhou Yongchang chief editor)

Selection and the ring-type of splitting bony site are split bone, split bony site and get shin, femur end (near the epiphysis) because inside all is that the spongiosa flesh and blood is transported, osteoblast is many here.See that from the bone cross section splitting bone mainly is that ring-type is split cortical bone, because cortical bone osteolith content is high thereby firm not splitting can't drawing-off, the generally softer easy drawing-off of spongy bone; As be difficult for drawing-off and can enlarge with audiofrequency hydraulic and split the cross section.So-called audiofrequency hydraulic is exactly that annular water pocket is close to and is split bony site and transmit sound wave.

[three] summary of the invention: the deficiency at existing osteotomy heighten operation proposes the technical scheme that noinvasive does not have huge pain.Technical scheme of the present invention is to realize like this.

A kind of extracorporeal shock wave ring-type device for cracking bones, by surge generator, survey position finder, controller and frame etc. automatically and constitute, its feature treatment and the shared electron focusing sound head of location sound head, the electron focusing sound head has the loop configuration of loop configuration or inner ring type concave surface, the inwall of loop configuration or inner ring type concave surface wall are inlayed piezoelectric patches, paste piezoelectric patches in the annular water pocket.Described a kind of extracorporeal shock wave ring-type device for cracking bones, its feature electron focusing sound head link an end by two semi-circular device one ends by hinge and constitute by hasp connection institute.Described a kind of extracorporeal shock wave ring-type device for cracking bones, its feature is selected for use audible region can adopt the continous way mode or is selected for use supersonic range can only adopt the batch (-type) mode

Advantage of the present invention: no wound, do not have huge pain, low, the easy enforcement of cost.

[four] description of drawings: Fig. 1 is an electron focusing sound head embodiment sketch map (loop configuration).Fig. 2 is an electron focusing sound head embodiment sketch map (loop configuration that internal ring is recessed).

[five] specific embodiment: embodiment is further described below in conjunction with accompanying drawing.

A kind of embodiment of extracorporeal shock wave ring-type device for cracking bones, by surge generator, survey position finder, controller and frame automatically and constitute, on and off switch, output intensity actuator, output reading instument, intervalometer, impulse modulation device etc. are housed on the controller panel.Pulse duty factor 1: 20-1: 50, cycle is millisecond or second, timing range 0-15 minute, ultrasound intensity 0.1-0.4w/cm. treatment and the shared electron focusing sound head of location sound head, the electron focusing sound head has loop configuration (Fig. 1), inlay 800-1200 piezoelectric patches on the inner surface of loop configuration (Fig. 1), paste piezoelectric patches in the annular water pocket.The electron focusing sound head links an end by two semi-circular devices (1,2) end by hinge and is constituted by the hasp connection.Being provided with sound frequency rate and supersonic frequency frequency selects.

Energized during use, load onto the electron focusing sound head and annular water pocket is close to and split bony site splitting bony site, selected continous way audio frequency gear of rotation adjusting knob or the ultrasonic gear of batch (-type), the natural frequency of selected cortical bone or osteolith is in order to resonance, set intervalometer, open the detection position finder, electronics automatic focus cortical bone (each piezoelectric patches vibrations emission sound wave comes together on the ring focusing line-and many focuses on the cortical bone cross section constitute, produce audio frequency or moment the ultrasonic bone that splits, each piezoelectric patches also can receive echo and focus on for surveying the dynamic autoelectrinic of position finder).Extend 0.5-1mm as cortical bone ring crack every day with being pre-applied on the lower limb securing elongated device.
