The technical problems to be solved in the utility model can also be come further to realize by the following technical programs, and the degree of depth of described link slot is 1mm-10mm.Link slot arranges such structure, the absorption damage can alleviate sucking-off calculus time, urinary tract mucosa being caused, the calculus granule that can not hinder negative-pressure adsorption to smash again simultaneously.
The technical problems to be solved in the utility model can also be come further to realize by the following technical programs, and described projection height interval arranges, and the top of high projection is than the high 0.1mm-0.5mm in the bottom of low depression.Make like this between projection in picturesque disorderly, form small zigzag, smash the better effects if of calculus.
The technical problems to be solved in the utility model can also be come further to realize by the following technical programs,
The tail end of described tubulose shank is provided with is with externally threaded union joint.
The technical problems to be solved in the utility model can also be come further to realize by the following technical programs,
Described protruding quantity is 3-6.Projection quantity is arranged within the scope of this, and gravel particle is even, and granular size makes cleaning effect better.
The technical problems to be solved in the utility model can also be come further to realize by the following technical programs,
Described protruding quantity is 5.Projection quantity is arranged within the scope of this, and gravel particle is even, and granular size makes cleaning effect best.
The technical problems to be solved in the utility model can also be come further to realize by the following technical programs, and described protruding axial cross section is triangle,
The technical problems to be solved in the utility model can also be come further to realize by the following technical programs,
Described tubulose shank, projection and union joint are stainless steel.
Compared with prior art, this utility model is in the process of technical solution problem, obtain following technique effect: by the front end end face at tubulose shank, some projections with circular-arc end are set, in the process of rubble, ultrasonic probe for breaking stone and calculus Multi-contact, under mechanical force same as the prior art, increase several times pressure, make calculus be easy to smash, clear up, simplified operating procedure, improved rubble and clear stone efficiency, shorten operating time, can also avoid related complication.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Embodiment.As shown in Figure 1, a kind of ultrasonic probe for breaking stone, comprise tubulose shank 2, the front end end face of described tubulose shank 2 is provided with at least 2 with it integrated protruding 4, described projection 4 is the extension of tubulose shank 2, described protruding axial cross section is triangle or rectangle, between protruding 4 roots, is provided with circular-arc link slot 3, and the top end face 5 of projection is arc surface.Projection is the extension of tubulose shank, and the thickness of projection is identical with the thickness of tubulose shank, and the bus of projection and the bus of tubulose shank are on same straight line.
The degree of depth of preferred link slot is 1mm-10mm, and preferred, the degree of depth of link slot is 5mm.
Preferably, projection 4 height intervals arrange, and projection 4 comprises high protrusion element and the low protrusion element that space arranges, and the top of high projection is than the high 0.1mm-0.5mm in the top of low projection, and as preferably, the top of high projection is than the high 0.4mm in the top of low projection.
The tail end of tubulose shank is provided with is with externally threaded union joint 1.
Preferably, protruding 4 quantity can be 3-6, and more preferably, protruding 4 quantity are elected 5 as.
Tubulose shank 2, projection 4 and union joint 1 are stainless steel.
In cleaning renal calices when calculus, probe for breaking stone of the present utility model enters into renal calices by kidney mirror, because the front end end face of tubulose shank arranges some projections with circular-arc end, in the process of rubble, ultrasonic probe for breaking stone and calculus Multi-contact, under mechanical force same as the prior art, increase pressure, make calculus be easy to smash, clear up, simplified operating procedure, improved rubble and clear stone efficiency, shorten operating time, can also avoid related complication.
Preferably, described tubulose shank 2 is hollow structure, and irrigating solution and calculus bits can attract equipment sucking-off external by negative pressure of vacuum by hollow space, thereby realizes the therapeutic purposes of the clear stone of rubble.
