Abstract

The utility model discloses a zygomatic osteotome. The zygomatic osteotome comprises an osteotome handle (1) and an osteotome head (2) positioned at the head part of the osteotome handle (1), and is characterized in that the osteotome head (2) comprises both an osteotome blade part with an osteotome blade (3) and a positioning part (4), the positioning part (4) is a protrusion extending outwards from the left side or the right side of the osteotome blade part, the positioning part (4) is obtuse and is in the length of 3mm-5mm and in the width of 2mm-4mm, the osteotome head (2) is bent downwards from the joint between the osteotome head (2) and the osteotome handle (1), and the bending angle ranges from 30 to 40. The zygomatic osteotome overcomes the shortcomings that a common osteotome is inaccurate in positioning and has high probability of displacement in the osteotomy process to lead the zygomatic arch to be completely fractured, and consequently, the face centers are drooping at a specified future date due to masticatory muscle contraction, achieves accuracy, quickness and safety in zygomatic arch osteotomy, and has the advantages of simple structure and strong practicability.

Description

A kind of cheekbone cutter

Technical field

This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of cheekbone cutter that can accurately locate when zygomoplasty.

Technical background

Decorative sursery adopts the method for zygomatic arch osteotomy to improve zygomatic arch evagination deformity usually, to reach the purpose of facial bone shaping.

In prior art, the zygomatic arch osteotomy does not have special-purpose bone cutting chisel, thereby generally adopts common bone cutting chisel to carry out osteotomy to zygomatic arch.And the osteotomy visual area of common bone cutting chisel is narrow and small, and inconvenience is observed, thereby the displacement of osteotomy line occurs because can't accurately locating the osteotomy line in art, causes complete fracture, and at a specified future date can face to occur sagging, uses common bone cutting chisel larger to zygomatic arch osteotomy risk.

Summary of the invention

The purpose of this utility model is exactly the problem that exists in order to overcome above-mentioned prior art, and a kind of cheekbone bone cutting chisel of special use is provided, and this cheekbone cutter can accurately be located the osteotomy line, reduces the risk of zygomatic arch complete fracture in the osteotomy process.This cheekbone cutter can significantly shorten operating time, improves operation safety.

In order to realize above-mentioned purpose of the present utility model, provide following technical scheme:

A kind of cheekbone cutter comprises, chisel grip is positioned at the chisel head of chisel grip head, it is characterized in that, described chisel head comprises chisel edge section and the location division with chisel edge, and wherein the location division is from chisel edge section left side or the outward extending projection in right side.

Preferably, described location division is obtuse, and its length range is between 3mm ~ 5mm, and width range is between 2mm ~ 4mm.

Preferably, described chisel head is bent downwardly from the junction with chisel grip, and the angle of bend scope is between 30 ° ~ 40 °.

Wherein, described chisel edge is the single face sword, and shrinks formation from top to bottom in the chisel head end.

Wherein, described chisel grip and chisel head are one-body molded.

Preferably, the length range of described chisel grip is between 270mm ~ 370mm, and width range is between 7mm ~ 11mm.

Preferably, described chisel head in the projected length scope of horizontal plane between 20mm ~ 40mm.

In addition, the end of described chisel grip has obtuse handle tail, and the cross-sectional area of described handle tail is larger than chisel grip.

In addition, the surface of described chisel grip has anti-skidding frosted or antiskid particles.

The beneficial effects of the utility model embody in the following areas:

The projection that this cheekbone cutter is provided for locating in the chisel head end can overcome the complete fracture risk that common bone cutting chisel causes because of displacement; The chisel head of the downward smooth curved of this cheekbone cutter can be deepened the visual area, accurately the location; Use this cheekbone cutter can significantly shorten operating time, improve operation safety.This utility model is simple in structure, and is safe and practical, and cost is low.

The specific embodiment

Fig. 1 is that a kind of position point of this utility model is in the front view of the cheekbone cutter in chisel edge section left side; Fig. 2 is the top view that cheekbone shown in Figure 1 is cut a hole; Fig. 3 is that a kind of position point of this utility model is in the front view of the cheekbone cutter on chisel edge section right side; Fig. 4 is the top view that cheekbone shown in Figure 3 is cut a hole.Cheekbone cutter shown in this utility model Fig. 1 (Fig. 2) and Fig. 3 (Fig. 4) is a cover, is respectively used to aim at the osteotomy line of zygomatic arch upper limb and lower edge in operation.

As shown in Figure 1, 2, a kind of cheekbone of this utility model cutter comprises, chisel grip 1 is positioned at the chisel head 2 of chisel grip 1 head.Particularly, chisel head 2 comprises with the chisel edge section of chisel edge 3 and location division 4, and wherein, location division 4 is from the chisel edge section outward extending projection in left side.

As shown in Figure 2, location division 4 is obtuse, and this obtuse structure can be protected all the other organ or tissues when the location, in order to avoid sustain damage.The length range of location division 4 is between 3mm ~ 5mm, and width range is between 2mm ~ 4mm.Positioning action is played in this location division 4 in art, to prevent chisel edge 3 lateral displacements in the osteotomy process.

As shown in Figure 1, chisel head 2 is bent downwardly from the junction with chisel grip 1, and the angle of bend scope is between 30 ° ~ 40 °.This crooked chisel head 2 can help to deepen the visual area, looks lower osteotomy blind.

As shown in Figure 1, chisel edge 3 is single face swords, and shrinks formation from top to bottom in chisel head 2 ends.

During concrete enforcement, chisel grip 1 of the present utility model is one-body molded with chisel head 2.The length range of chisel grip 1 is between 270mm ~ 370mm, and width range is between 7mm ~ 11mm.Chisel head 2 in the projected length scope of horizontal plane between 20mm ~ 40mm.

As shown in Figure 1, 2, the end of chisel grip 1 has obtuse handle tail 5, and the cross-sectional area of handle tail 5 is larger than chisel grip 1; In addition, the surface of chisel grip 1 has anti-skidding frosted or antiskid particles, prevents that hand from skidding and causing the operation error.

As shown in Fig. 3,4, a kind of cheekbone of this utility model cutter comprises, chisel grip 1 is positioned at the chisel head 2 of chisel grip 1 head.Particularly, chisel head 2 comprises with the chisel edge section of chisel edge 3 and location division 4, and wherein, location division 4 is from the chisel edge section outward extending projection in right side.

As identical in the cheekbone cutter that the cheekbone in Fig. 3,4 is cut a hole in all the other structures and Fig. 1,2, do not repeat them here.

Below introduce in detail detailed step when using this utility model osteotomy.

Be ready to the to perform the operation corresponding apparatus of use, the chisel edge 3 of looking at lower the cheekbone that adapts cutter straight are aimed at respectively the osteotomy line that zygomatic arch upper limb or lower edge are drafted, and make location division 4 tighten respectively the zygomatic arch edge.The beginning osteotomy is first touched the bone cutting chisel rear end with hammer, until osteotome enter cortical bone stable after, then hammering osteotome rear end firmly until transfix the zygomatic arch sclerotin, then is carried out other osteotomy and is operated.

Because the zygomatic arch width narrows down from front to back gradually, therefore for the cheekbone of every side face when the osteotomy, need to select according to the width of zygomatic arch the cheekbone cutter of four different in width chisel edges 3.

Although above-mentioned this utility model is described in detail; but this utility model is not limited to this; those skilled in the art can modify according to principle of the present utility model; therefore, all various modifications of carrying out according to principle of the present utility model all should be understood to fall into protection domain of the present utility model.
