Abstract
The invention relates to the technical field of clamping devices, in particular to a medical screw clamping device which comprises a clamping head. The rear end of the clamping head is sequentially and fixedly connected with a clamping pipe and a rear base. The clamping head is provided with a clamping hole in the axial direction. Three wedge-shaped grooves arranged equally are formed in the clamping hole in the circumferential direction. The clamping device can be used for clamping medical screws and especially the miniature medical screws.
Description
Technical field
The present invention relates to the technical field of clamper, especially a kind of Medical screw clamper.
Background technology
The operative doctor of hospital often can be used screw in concrete operation technique work; these screws are generally miniature screw thread; due to its small volume; so clamping miniature screw thread is a very difficult thing; for clamp screws easily and fast; medical field urgently needs a kind ofly can facilitate clamp screws, especially clamps the professional tool of miniature screw thread.
Summary of the invention
The technical problem to be solved in the present invention is: in order to solve the problem proposing in above-mentioned background technology, the invention provides a kind of Medical screw clamper, it can be used for clamping Medical screw, especially clamps miniature Medical screw.
The technical solution adopted for the present invention to solve the technical problems is: a kind of Medical screw clamper, comprise chuck, the rear end of chuck is fixedly connected with clamp and back seat in turn, on the axial direction of chuck, offers clamping hole, offers three grades and divide the wedge-shaped slot of setting on the circumferencial direction of clamping hole.
In order to extend homogenize chucking power, thus on the circumferencial direction of clamp, offer three grades divide arrange and with the straight shape groove of three corresponding connections of wedge-shaped slot on described clamping hole.
For the ease of the matching used extension pipe of clamper and its, be connected, therefore the sidewall of back seat offers two installing holes that relatively distribute.
Beneficial effect of the present invention: this Medical screw clamper simple and reasonable, can be used for clamping Medical screw, especially clamp miniature Medical screw, clamp fasteningly, convenient to operation, can rapidly Medical screw be imported or be derived.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation one of the present invention;
Fig. 2 is structural representation two of the present invention;
Fig. 3 is the structural representation at A place in Fig. 1;
Fig. 4 is the structural representation at B place in Fig. 2.
In figure: 1, chuck, 2, clamp, 3, back seat, 4, clamping hole, 5, wedge-shaped slot, 6, straight shape groove, 7, installing hole.
The specific embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention is only described in a schematic way, so it only show the formation relevant with the present invention.
Medical screw clamper as shown in Figure 1, Figure 2, Figure 3 and Figure 4, comprise chuck 1, the rear end of chuck 1 is fixedly connected with clamp 2 and back seat 3 in turn, offers clamping hole 4 on the axial direction of chuck 1, offers the wedge-shaped slot 5 that three grades are divided setting on the circumferencial direction of clamping hole 4.
Wherein on the circumferencial direction of clamp 2, offer three grades divide arrange and with the straight shape groove 6 of three wedge-shaped slot 5 corresponding connections on described clamping hole 4.The sidewall of back seat 3 offers two installing holes 7 that relatively distribute.
Screw plug, in clamping hole 4, by clamping hole 4 three wedge-shaped slots 5 around, makes that screw is more resilient to be held, to import or derive.Three straight shape grooves 6 that are connected with three wedge-shaped slots 5, make chucking power more even, and ductility is strong.
The above-mentioned foundation desirable embodiment of the present invention of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this invention technological thought, carry out various change and modification completely.The technical scope of this invention is not limited to the content in description, must determine its technical scope according to claim scope.
