Abstract
Portable external ultrasonic lithotriptor is made up of supersonic sounding instrument and transducer.The transducer of the peripheral low frequency of mesopore high frequency is associated between pulse generator and the preamplifier.The front and back of piezoelectric chip split acoustic lens and damping thing, and periphery is to link to each other with push-pull handle to have movable interior cover, the shell of dome-shaped cover.Between shell and the movable interior cover is entrant sound liquid.Ventilative window is sealed by the entrant sound diaphragm.Be rubber cushion between outer housing and entrant sound diaphragm.This machine advantage is to locate easy; The work noiseless; Little to injury of human; Can smash little calculus, to cause litholysis.
Description
The invention belongs to the design and the manufacturing technology field of extracorporeal lithotiptor.
Existing extra chock wave lithotriptor is to collide half ellipsoid rustless steel wall of cup, generation with the shock wave that the discharge of water mesohigh takes place to reflect, and focuses on a bit.On placing a bit by B ultrasonic or lonizing radiation again, make its fragmentation to the calculus of precrushing in the human body.Its shortcoming is, the rubble point can not directly observe, to the bit comparison difficulty.Because respiratory movement is swung calculus, each shock wave not necessarily can both hit on the calculus in the human body.In addition, the shock wave wave amplitude is wide, and frequency spectrum is also wide; The electrion energy is big, and effective energy is not concentrated, and bigger to injury of human in shattering process, and is bigger to surrounding environment influence yet.
The objective of the invention is, the shortcoming at existing extra chock wave lithotriptor provides a kind of external supersonic lithotrite.
Structure of the present invention as shown in Figure 1.Form by main frame-ultrasonic depth finder and transducer.Transducer is associated in the main frame between the pulse generator and preposition amplification.The focused transducer of mesopore high frequency, peripheral low frequency, its focus is adjustable in the intravital distance of people.The structure of transducer as shown in Figure 2.Acoustic lens (12) is put in the front of piezoelectric chip (11), damping thing (10) is put in the back.Its periphery is a cover (9) in link to each other with push-pull handle (3) movable, and the outside of movable interior cover (9) is shell (7), and overcoat (7) joins with dome-shaped cover (5), and a rubber seal (6) is arranged between the two.Dome-shaped cover (5) is sleeved on push-pull handle (3) outside, and two sealing rings (4) are arranged between the two, and cable (1) is glue envelope (2) by passing in the push-pull handle (3) between push-pull handle (3) and the cable (1).Between shell (7) and the movable interior cover (9) is entrant sound liquid (8), and Oleum Ricini can be done entrant sound liquid.The window of the anterior sound transmitting window of transducer is sealed by entrant sound diaphragm (16).Between outer housing (13) and the entrant sound diaphragm (16) rubber cushion (15) is arranged.Between entrant sound diaphragm (16) and the movable interior cover (9) rubber gasket (14) is arranged.Piezoelectric chip (11) can be made concave surface and focus on shape, and removes acoustic lens (12).Be that the concave surface piezoelectric chip has piezoelectric chip and two kinds of functions of acoustic lens.
The manufacture method of portable external ultrasonic lithotriptor is:
Purchase parts assembling transducer by the processing of the structure of Fig. 2, debug between the pulse generator that is connected in the supersonic sounding instrument after qualified and the preposition amplification and get final product.
Operation principle of the present invention is:
Utilize the focus energy of ultrasound emission to smash patient's calculi in vivo.By ultrasonic reflection, be presented on the oscillography screen by receiving lines more earlier, determine focus and observe calculus whether place on the focus.Determine the calculus point intuitively like this.
The present invention has model machine, and its frequency is 20KH
2, adjustable power.Through clinic trial, respond well.
The using method of this machine is:
Carry out the cross location at B ultrasonic, measure the distance of patient's calculus and skin, the centre fixed point is changed into transducer.According to the distance of calculus of measuring and skin, hyperacoustic depth of focus takes place in the debugging transducer, checks whether focus is accurate, changes the super head check and correction of A, and focus can be launched after accurately, rubble.
Advantage of the present invention is, ultrasound wave is high frequently, frequency spectrum is fixed, high directivity, concentration of energy; But direct observation rubble point and focus; This machine is a portable, can swing transducer with patient respiratory, and energy is all handed on calculus, and is little to injury of human; The work noiseless does not have influence to surrounding; Because ultrasound wave is short, uses calculus broken forr a short time, even can reach dissolved degree.
