Abstract
The utility model proposes the special pneumatic ballistic lithotripsy probe of a kind of Urology Surgery, comprise probe base portion and probe, probe and probe base portion are connected, and described probe end sides has groove, be provided with the sawtooth tilted towards probe base portion in groove, the height of described sawtooth is concordant with groove height.During rubble, its indented sides is pushed down calculus, during rubble, probe its indented sides in extensional vibration process produces the cutting force moved back and forth to calculus, thus calculus is smashed, and avoids calculus to be shifted.
Description
Technical field
This utility model relates to medical instruments field, particularly the special pneumatic ballistic lithotripsy probe of a kind of Urology Surgery.
Background technology
Existing URL technology utilizes the bullet moved back and forth at a high speed in trajectory repeatedly to clash into probe, makes probe produce extensional vibration, thus smash calculus.Therefore, during rubble, probe front just must be clashed into calculus, calculus could be smashed.For activeness calculus, this impact force often makes calculus forward end be shifted, especially proximal ureteral calculus, can impact in kidney by calculus, causes rubble failure.And if push down calculus rubble with probe side, because its side is smooth, cannot calculus be pushed down.Even if push down calculus, when rubble, due to the vibration of probe, calculus is easily slippage also, effectively can not smash calculus.
Summary of the invention
For solving above-mentioned prior art Problems existing, the utility model proposes the special pneumatic ballistic lithotripsy probe of a kind of Urology Surgery.Probe front side of the present utility model indentation, during rubble, pushes down calculus by its indented sides, during rubble, probe its indented sides in extensional vibration process produces the cutting force moved back and forth to calculus, thus calculus is smashed, and avoids calculus to be shifted.
For achieving the above object, the technical solution of the utility model is:
The special pneumatic ballistic lithotripsy probe of a kind of Urology Surgery, comprise probe base portion and probe, probe and probe base portion are connected, and described probe end sides has groove, be provided with the sawtooth tilted towards probe base portion in groove, the height of described sawtooth is concordant with groove height.
Further, the angle of inclination of described sawtooth is 0-30 °.
Further, the tip of described groove and sawtooth is smooth circular arc.
Relative to prior art, the beneficial effects of the utility model are: probe front side of the present utility model indentation, during rubble, its indented sides is pushed down calculus, during rubble, probe its indented sides in extensional vibration process produces the cutting force moved back and forth to calculus, thus calculus is smashed, and avoids calculus to be shifted.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
Wherein, 1-probe base portion, 2-probe, 3-groove, 4-sawtooth.
Detailed description of the invention
Below in conjunction with the drawings and the specific embodiments, this utility model content is described in further detail:
As shown in Figure 1, the special pneumatic ballistic lithotripsy probe of a kind of Urology Surgery, comprise probe base portion 1 and probe 2, probe 2 and probe base portion 1 are connected, described probe 2 end sides has groove 3, be provided with the sawtooth 4 tilted towards probe base portion 1 in groove 3, the height of described sawtooth 4 is highly concordant with groove 3.
Further, the angle of inclination of described sawtooth 4 is 0-30 °.
Further, the tip of described groove 3 and sawtooth 4 is smooth circular arc.
Operation principle of the present utility model is: side, probe 2 front end of the present utility model is provided with groove 3, and be provided with the sawtooth 4 tilted towards probe base portion 1 in groove 3, the height of described sawtooth 4 is highly concordant with groove 3., during rubble, calculus is pushed down in sawtooth 4 side, during rubble, probe its indented sides in extensional vibration process produces the cutting force moved back and forth to calculus, thus calculus is smashed, and avoids calculus to be shifted.And smooth circular arc is arranged on sawtooth 4 top, avoids sawtooth 4 in operation and hook tissue because of carelessness, Accessory injury occurs.
The above, be only detailed description of the invention of the present utility model, but protection domain of the present utility model is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
