Description
Technical field
This utility model relates to a kind of micro broken stone device, particularly relates to a kind of being applicable to and pulverizes the medical miniature lithotrite of taking out in the human body urinary system calculus body that comprises kidney, ureter, bladder and urethra.
Background technology
Urinary system calculus is the general designation of position calculus such as kidney, ureter, bladder and urethra, is one of common disease of urinary system.
Traditional calculi therapy method mainly comprises medicine lithagogue method, extracorporeal shock-wave lithotomy method and surgical calculus removing method.Wherein, the medicine lithagogue method has certain effect to microlith, but generally, need reach the treatment time of some months; The extracorporeal shock-wave lithotomy method at first is broken into powder by shock wave with calculus, discharge by human body natural's tract then, but the extracorporeal shock-wave lithotomy method is only applicable to be no more than 2cm, monistic calculus; The surgical calculus removing method at be the huge gallstone of complexity, though adopt the surgical calculus removing method can eliminate calculus, also be tangible to the injury of human body.Kidney stone particularly, the surgical calculus removing method must cause damage to renal function.
In the modern medicine, the method that is used for the treatment of urinary calculi comprises the shock wave stone crusher rubble, electrohydraulic lithotripsy, ultrasonic rubble, lithotrite rubble, pneumatic ballistic lithotripsy and holmium laser lithotripsy etc.Wherein, the pneumatic ballistic lithotripsy technology is to be applied to clinical Urology Surgery intracavity rubble new technique last century end, is applicable to various lithangiuriaes.Its process is by the microchannel that urethra or percutaneous kidney are set up endoscope directly to be inserted into the calculus place, under telescreen monitors, utilize pneumatic ballistic lithotriptor that calculus is smashed into little granule, get stone, can realize one-time cure, remedy the deficiency of extracorporeal shock-wave lithotripsy greatly.Since do not produce heat effect during operation, very slight to the damage of ureter and renal tissue.We can say that URL provides Wicresoft, economic treatment means for the urinary system calculus patient.
But the pneumatic ballistic lithotriptor that uses clinically is made up of bigger air compressor and control section at present, and floor space is bigger, is not easy to carry, and has brought limitation for the use of pneumatic ballistic lithotriptor.
The utility model content
This utility model aim to provide a kind of volume of using pneumatic ballistic lithotripsy method treatment urinary calculi little, in light weight, be easy to carry and move, economy and durability, and can realize disposable medical miniature lithotrite.
The technical scheme of this utility model medical miniature lithotrite is as follows:
This utility model medical miniature lithotrite comprises rubble pin, rubble pin medicated cap, bullet, steam vent, trajectory, trigger, body, high-pressure mini gas cylinder and power hammer; The tail end of described rubble pin leave can acceptance the groove of hammer, the tail end of described rubble pin is arranged in the rubble pin medicated cap, described rubble backshank end and power tup end are close to, the equal diameters of described bullet and trajectory internal cavity, described power hammer tail end diameter has cavity less than the diameter of bullet in the middle of the described trajectory, on the wall of described cavity steam vent is arranged, when described lithotrite was not in user mode, bullet was in the top of cavity wall upper air-vent.Be provided with the annular gap between cavity wall and the trajectory wall, the trajectory wall is provided with steam vent, and described trajectory is fixed on the body, and described body also is fixedly connected with trigger and high-pressure mini gas cylinder.
Further, the gas in the described high-pressure mini gas cylinder is compression CO
2Perhaps compressed air.
Further, described high-pressure mini gas cylinder is detachable.
The beneficial effect of this utility model medical miniature lithotrite is:
(1) described lithotrite volume little, in light weight, be easy to carry and move;
(2) described lithotrite dispense with outer connecting power, thus safety and the convenience used increased;
(3) described rubble pin and high-pressure mini gas cylinder are disposable use device, can reduce the probability of patient's cross infection;
(4) described lithotrite lithotrity effect is reliable, the rubble time is short, efficient is high, simple to operate, safety, and the patient recovers soon, economy and durability.
Description of drawings
Fig. 1 is the structural representation of this utility model medical miniature lithotrite;
1, rubble pin, 2, rubble pin medicated cap, 3, steam vent, 4, bullet, 5, trajectory, 6, trigger, 7, body, 8, the high-pressure mini gas cylinder, 9, the power hammer.
The specific embodiment
Referring to accompanying drawing 1, this utility model medical miniature lithotrite comprises rubble pin 1, rubble pin medicated cap 2, steam vent 3, bullet 4, trajectory 5, trigger 6, body 7, high-pressure mini gas cylinder 8 and power hammer 9; The tail end of described rubble pin 1 leaves and can hammer 9 groove into shape by acceptance, the tail end of described rubble pin 1 is arranged in the rubble pin medicated cap 2, described rubble pin medicated cap 2 tail ends are fixedlyed connected with trajectory 5 head ends, described bullet 4 can be moved into the projection that power is hammered 9 tail ends into shape, the equal diameters of the diameter of bullet 4 and trajectory 5 internal cavities, power is hammered the diameter of 9 tail end diameters less than bullet 4 into shape, in the middle of the described trajectory 5 cavity is arranged, steam vent 3 is arranged on the wall of described cavity, when described lithotrite is not in user mode, bullet 4 is in the bottom of cavity wall upper air-vent 3, make between the tail end of bullet 4 and cavity wall and form enclosed space, referring to accompanying drawing 2, when bullet 4 power of being moved to were hammered 9 tail ends into shape, bullet 4 was on the steam vent 3 of cavity wall, be provided with the annular gap between cavity wall and trajectory 5 walls, trajectory 5 walls are provided with steam vent, and described trajectory 5 is fixed on the body 7, and described body 7 also is fixedly connected with trigger 6 and high-pressure mini gas cylinder 8.
