Description
Technical field
The utility model, which is related to, minimally invasive takes Stone technique field, more particularly to microtrauma type kidney stone stone taking device.
Background technology
Kidney stone is current clinical common disease, refers to and betides kidney calices, the knot of renal plevis and renal plevis and urine output pipe jointing part
Stone.Kidney is the lithogenous main portions of urinary system shape, and ureteral calculi is almost all from kidney, and kidney stone is than other any portions
Position calculus is more easy to coup injury kidney.The most frequently used modus operandi of kidney stone is pyelolithotomy, the kidney of current Clinical practice
The plane that stone face is shallow band is taken, calculus in kidney is gripped with it, lithotomy forceps contacts small with calculus, is only capable of clamping calculus one end, no
It is easy to take out, very big difficulty is brought to operation.
Existing Chinese patent CN201855292U provides a kind of Meshy stone-picking device for having a handles with holes.By outer sheath, hand
Handle, traction seal wire and lithotomy net composition；Draw seal wire and lithotomy net is located inside outer sheath, handle is by drawing seal wire and taking stone
Net is connected；Handle includes four single hole operating handles.Outer sheath is inserted near calculus when using, pushing handle makes lithotomy net
In deployed condition, each single hole operating handle for handle of pulling back respectively makes lithotomy net wrap up calculus and take out.
But above-mentioned technical operation is complicated, it is necessary to control four hand adjustment arthrolith net and then wrap up calculus.Stone net wire side compared with
Greatly, it is impossible to which specific aim extracts target calculus.And the more difficult selection in aperture of above-mentioned design stone net, mesh too maximum size can spill, too
It is small, need, by calculus-smashing to small grain size, to increase workload.
Utility model content
The purpose of this utility model is to provide microtrauma type kidney stone stone taking device, the existing kidney stone taking device surface of a wound of solution
Greatly, the problem of complex operation.
To achieve the above object, above-mentioned technique effect is reached, the utility model solves above-mentioned ask by the following technical programs
Topic：
The action bars of suit, is connected with action bars front end in microtrauma type kidney stone stone taking device, including outer sheath, outer sheath
Grabbing device, what the grabbing device included end buckle takes stone pawl, described to take stone pawl bottom to be hinged with action bars.
Take stone pawl bottom to be connected through the hinge with action bars, take stone pawl end to be rotated around action bars, so, take stone
Pawl can reach the effect of opening and closing.Outer sheath is touched, the grabbing device being connected with action bars is moved relative to after outer sheath, this
When take stone pawl by outer sheath radial compression applied, close automatically and capture target calculus.
It is described to take stone pawl medial surface and action bars as the improvement of the above-mentioned microtrauma type kidney stone stone taking device of the utility model
Between be connected with elastic thrust element.Take stone pawl bottom to be connected through the hinge with action bars, take stone pawl can be in opening or closure
State.In order to effectively control the working condition for taking stone pawl, elastic thrust element is set, is not affected by when taking stone pawl from outer sheath
During radial pressure, in the presence of elastic thrust element, the open-shaped state of stone pawl is taken；When taking stone pawl by the footpath from outer sheath
During to pressure, the effect of stretching that pushes away of elastic thrust element is suppressed, and takes stone pawl synchronizing close in the presence of radial pressure, it is to avoid
Because pawl stitches spacing, calculus is from taking stone pawl seam situation about tumbling.
As the improvement of the above-mentioned microtrauma type kidney stone stone taking device of the utility model, the grabbing device takes stone using three
Pawl is adjacent to take the distance between stone pawl identical.Triangle has stability, the characteristics of having firm, firm, pressure-resistant.Set three
It is individual to take stone pawl, calculus is captured using the stability of triangle, the stability for taking stone is improved.Adjacent take between stone pawl is set simultaneously
Apart from identical, the situation generation of gap inequality between pawl is avoided that, prevents calculus from being dropped between pawl seam, influence takes stone effect.
As the improvement of the above-mentioned microtrauma type kidney stone stone taking device of the utility model, the action bars front end face is adjacent to take
Interstitial site between stone pawl is provided with axially extending bore.During stone is taken, it often may require that some miscellaneous functions of addition to take
What lapicide made is smoothed out, such as flusher, aerating device, visual device, lighting device etc.., can by setting axially extending bore
Effectively improve the practicality and applicability of device.
As the improvement of the above-mentioned microtrauma type kidney stone stone taking device of the utility model, the axially extending bore is placed with endoscope
Insertion section, insertion section is connected through through hole tail end with endoscope main body.It is minimally invasive take stone treat in, because of the surface of a wound of Minimally Invasive Surgery
It is small, all aid in visual device to feed back inner case often through endoscope, reach the effect for fast and safely taking stone.
The beneficial effects of the utility model are：
1st, take stone pawl bottom and action bars to be hinged, by setting ring set type structure, be applied to using outer sheath and take stone pawl footpath
The closure at pawl end is realized to pressure.
2nd, the working condition of stone pawl is taken for effectively control, being provided with elastic thrust element makes to take the open-shaped state of stone pawl.When
When the radial pressure of outer sheath suppresses the effect of elastic thrust element, stone pawl synchronizing close in the presence of radial pressure is taken, is kept away
Exempt from pawl seam spacing, calculus is tumbled from taking the gap of stone pawl.
3rd, action bars front end face, the adjacent interstitial site taken between stone pawl is provided with axially extending bore.Stone process is taken to add one
A little miscellaneous functions, by setting axially extending bore to place auxiliary equipment, can effectively improve the practicality of device in order to take lapicide to make
And applicability.
It is big that the utility model can preferably solve the existing kidney stone taking device surface of a wound, the problem of complex operation.
