Description
Technical field
This utility model belongs to technical field of medical instruments, specifically, and particularly a kind of Kirschner wire chuck of medical core drill mobile phone.
Background technology
In the osseous tissue operation, often to use Kirschner wire to operations such as osseous tissue position.On the core drill mobile phone, the Kirschner wire bit diameter is less by special-purpose chuck clamping for Kirschner wire, and length is longer, and general diameter is no more than 4mm, and length can reach more than the 200mm.During boring, the Kirschner wire drill bit only exposes the about 20-30mm of chuck front end, pierce certain depth after, unclamp chuck, mobile backward core drill mobile phone and the about 20-30mm of chuck clamp Kirschner wire then again, bore certain depth again, so repeatedly, get into desired depth until Kirschner wire.
At present, the core drill mobile phone generally adopts the three-jaw drill chuck to come the clamping Kirschner wire, will unclamp chuck with the wrench instrument of three-jaw drill chuck configuration behind the brill certain depth, treats to move on to certain position behind three-jaw drill chuck and the core drill mobile phone, and reuse wrench instrument screws chuck.Obviously, when boring was dark, such repeatable operation was very inconvenient, can influence the efficient and the quality of osseous tissue operation.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of Kirschner wire chuck of easy to operate medical core drill mobile phone.
The technical solution of the utility model is as follows: a kind of Kirschner wire chuck of medical core drill mobile phone, housing (1) is a hollow-core construction, in housing (1), be rotatably mounted with hollow spindle (2), be provided with thrust bearing (3) and pushing block (4) between this hollow spindle (2) and the housing (1), wherein an end of thrust bearing (3) is spacing by the step surface on the hollow spindle (2), the end face of the other end of thrust bearing (3) and pushing block (4) is fitted, described pushing block (4) is connected with handle (5), and handle (5) is articulated on the housing (1); In described hollow spindle (2), be provided with collet (6), the port taper fit of the collet segment of these collet (6) one ends and hollow spindle (2) corresponding end, the other end of collet (6) is by spring (7) and the interior step surface butt of hollow spindle (2).
Adopt above technical scheme, housing is connected with the core drill mobile phone, and the intravital hollow spindle of shell is connected with the output shaft of core drill mobile phone, and hollow spindle housing rotation relatively.In the time of the clamping Kirschner wire, earlier Kirschner wire is inserted in the housing, make Kirschner wire pass collet, then hold the handle of core drill mobile phone and the handle in this utility model, when holding handle with a firm grip, handle rotates around the pin joint of itself and housing, when handle rotates, promoting pushing block moves to the collet segment direction of collet, pushing block promotes the same moved further of hollow spindle by thrust bearing simultaneously, the collet segment of the conical surface pressuring spring chuck of hollow spindle port shrinks the collet segment of collet, and Kirschner wire is clamped.Drive the core drill mobile phone this moment, the output shaft of core drill mobile phone can drive hollow spindle, collet and Kirschner wire rotation, makes Kirschner wire carry out drilling operation.After piercing certain depth, unclamp handle, hollow spindle drives thrust bearing under the resilience force effect of spring and pushing block resets, the conical surface of hollow spindle port unclamps the compressing to the collet segment of collet, the collet segment of collet opens under the effect of self elastic force, unclamps the clamping to Kirschner wire.At this moment can suitably mobile backward core drill mobile phone and chuck, the handle of holding with a firm grip again in place clamps Kirschner wire once more and continues boring, so repeatedly until Kirschner wire being got into the needed degree of depth.This shows, this utility model not need by instrument just can realize to the clamping of Kirschner wire with unclamp, not only simple, convenient, and good reliability, can improve the efficient and the quality of osseous tissue operation greatly.
Described handle (5) is connected with housing (1) by rotating shaft (8), and the end of this handle (5) is formed with the ear pushing (5a) of two symmetric arrangement, and this ear pushing (5a) is stretched in the housing (1), and cooperates with notch (4a) clamping on the pushing block (4).Above structure easy accessibility, susceptiveness are good, and the handle of holding with a firm grip can be controlled pushing block and move, and have guaranteed only motion in the axial direction of pushing block.
Described handle (5) is a serpentine, and handsome in appearance like this, handling ease are operated convenient and labor-saving.
For simplified structure, convenient for assembly, described housing (1) is made of procapsid (1a) and back casing (1b), and procapsid (1a) connects with back casing (1b), and fixes by screw thread.
Structure is compact more, also further the raising hollow spindle moves and maintainability in order to make, in described procapsid (1a), be supported with end cover (10) by clutch shaft bearing (9), this end cover (10) is formed with spacing disk body near an end of collet (6), the end face of described one of them card of spacing disk body and clutch shaft bearing (9) is fitted, and the collet segment of another card of spacing disk body and collet (6) connects.
Be supported with lining (12) by second bearing (11) in described procapsid (1a), this lining (12) is slidingly matched with hollow spindle (2), and lining (12) is by end cover (10) and second bearing (11) axial limiting.Lining plays location and guiding to the end of hollow spindle, in the time of can preventing on the one hand the hollow spindle rotation and housing rub, on the other hand, can guarantee the axially movable smoothness of hollow spindle.
Described spring (7) is set on the spring base (13), this spring base (13) is the hollow sleeve structure, one end of spring base (13) stretches in the collet (6), spacing by the boss on the spring base (13), step surface butt in one end of described spring (7) and the boss butt, the other end of spring (7) and hollow spindle (2).Above structure can be guaranteed the axiality of spring and collet, prevented from like this when hollow spindle from moving axially circular runout to take place, and collet clamping Kirschner wire is more firm, reliable.
Beneficial effect: this utility model can realize fast under need not be by the situation of instrument to the clamping of Kirschner wire with unclamp, easy and simple to handle, laborsaving, clamping firmly, reliable, help improving the efficient and the quality of osseous tissue operation.
