Abstract

The utility model provides a broken nail slotting device which comprises a handle, two clamping pieces and a slotting cutter, wherein the two clamping pieces are hinged on the handle and engaged witheach other, a nail-clamping notch and a guide track groove are formed on each of the two clamping pieces and engaged with each other, the pedestal of the slotting cutter is inserted in the two guide track grooves and slides along the guide track grooves, a mini cam motor is fixed inside the handle, a connecting rod is hinged on the cam of the cam motor, and the other end of the connecting rod is hinged on the pedestal of the slotting cutter. The slotting cutter reciprocates on the surface of a broken nail to form a slot, and then the broken nail is unfastened and withdrawn by a screw driver. The saw teeth of the slotting cutter do not exceed the surface of the clamping pieces, thereby preventing the injury of any part of a human body and achieving good using effect.

Description

The broken nail notcher

Technical field:

This utility model relates to the orthopedic medical device technical field, the broken nail notcher when being used to take out broken nail in the bone.

Background technology:

In medical operating, often in patient's muscle or bone, implant nail because this nail is thinner, therefore rupture easily, head comes off, below a part be embedded in very difficult taking-up in muscle or the bone.Its reason is that the position of broken nail part is difficult to determine, might be vertical, also might be askew in muscle.Common taking-up mode is: by adjusting the angle and the position of broken end, broken end and broken nail are partly coincide, can determine the angle of broken nail, and then with the use that matches of hole making drill and two instruments of device for taking out broken nail, earlier the broken nail position animally open an aperture, the reuse device for taking out broken nail takes out broken nail.Its weak point is that common device for taking out broken nail is to utilize device for taking out broken nail to clamp broken end, rotates then and takes out, because broken end is less, is difficult for clamping, and is so very inconvenient.So people expect, open a groove on the broken end of broken nail, utilize screw to open rotation and take out, be difficult for hurting osseous tissue like this, it is also comparatively convenient to operate.

The utility model content:

The purpose of this utility model is to provide a kind of broken nail notcher, and it is simple in structure, and it can make things convenient for the doctor to open the back-out broken nail with screw easily at the broken end surface of broken nail fluting.

Technology solution of the present utility model is as follows:

The broken nail notcher, comprise handle 1, intermediate plate 2, necking tool 3, be hinged with two intermediate plates that match 2 on handle 1, have two clip nail notches 21 that match and guide-track groove 22 on the intermediate plate, base 31 sleeves of necking tool 3 slide along this guide-track groove 22 in two guide-track grooves 22;

Handle 1 internal fixation has miniature cam motor 4, is hinged with connecting rod 5 on the cam of cam motor 4, and the other end of connecting rod 5 is hinged on the base 31 of necking tool 3.

The switch 42 of described cam motor 4 is arranged on the handle 1.

The front end tool arc extension 23 of described intermediate plate 2.

Described two intermediate plates 2 adopt motorized motions to clamp, unclamp, and its motor switch is arranged on the handle 1.

The beneficial effects of the utility model are: during use, the clip nail notch of two intermediate plates clamps broken nail, starting cam motor then, and necking tool goes out groove at the surperficial reciprocating saw of broken nail head, opens the turn broken nail with screw then and can take out.The sawtooth of its necking tool can not surpass the surface of intermediate plate, so can not hurt any tissue of human body, result of use is good.

Description of drawings:

Fig. 1 is the schematic perspective view of this utility model embodiment 1;

Fig. 2 is the structural representation of necking tool drive part;

Fig. 3 is the annexation sketch map of necking tool and connecting rod;

The schematic perspective view of Fig. 4 embodiment 2.

The specific embodiment:

The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.

Embodiment 1, see that Fig. 1～3 show: broken nail notcher in the bone, comprise handle 1, intermediate plate 2, necking tool 3, on handle 1, be hinged with two intermediate plates that match 2, have two clip nail notches 21 that match and guide-track groove 22 on the intermediate plate, base 31 sleeves of necking tool 3 slide along this guide-track groove 22 in two guide-track grooves 22;

The switch 42 of described cam motor 4 is arranged on the handle 1.

The front end tool arc extension 23 of described intermediate plate 2.

Embodiment 2, and is shown in Figure 4: described two intermediate plates 2 adopt motorized motions to clamp, unclamp, and its motor switch is arranged on the handle 1.All the other are with embodiment 1.

Operation principle: during use, the clip nail notch 21 of two intermediate plates 2 clamps broken nail, and the starting cam motor 4 then, and necking tool 3 goes out groove at the surperficial reciprocating saw of broken nail head, opens the turn broken nail with screw then and can take out.The sawtooth of its necking tool 3 can not surpass the surface of intermediate plate, so can not hurt any tissue of human body, result of use is good.

The front end tool arc extension 23 of intermediate plate 2 among the embodiment 1 clamps for these extension 23 application of forces with hands to the broken end of broken nail.

Two intermediate plates 2 adopt motorized motions to clamp, unclamp among the embodiment 2.Electronic clamping some electronic clampings, the loose configuration commonly used now with unclamping employing gets final product.
