Description

Novel corner gum sword

Technical Field

The utility model relates to the field of medical equipment, more specifically relates to a novel corner gum sword.

Background

In the local oral surgery, the oral cavity far and middle, namely the back dental area, the upper jaw and the lower jaw which are not easy to see are often required to be operated, but because the front teeth block and the visual field in the gum surgery is not good, a conventional scalpel only has a knife edge in one direction, the back teeth are difficult to cut in, and a sharp knife cannot be smoothly pushed forward when running on the bone surface, a sharp knife tip can bounce to influence the operation, more importantly, the conditions of the oral surgery are extremely special, because the shapes of the teeth cause the undercut between the adjacent teeth, the undercut part easily influences the positions of a knife handle and the knife edge, and the positions of the adjacent gaps of the teeth cannot be reached or cut.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a gum cutter not only can conveniently open the not good position in art district field of vision, can also cut nearly well blind area gum root.

The utility model discloses a realize above-mentioned purpose, realize through following technical scheme:

the utility model provides a novel corner gum sword, includes handle of a knife and tool bit, and the tool bit attaches the two-way cutting edge that the cutting edge constitutes by arc cutting edge and back of the body, and arc cutting edge attaches the cutting edge with the back of the body and is two-sided edging, and the handle of a knife attaches the position that the cutting edge is adjacent with the back of the body and opens there is the arc recess, and the back of the body attaches the cutting edge and adopts half peach-shape, includes the hypotenuse of small circle cutting edge and both sides promptly, one side hypotenuse with the arc cutting edge meets, and opposite side hypotenuse incurving forms natural smooth curved surface with the arc recess.

Preferably, the curved edge is longer and thicker than the backing edge.

Preferably, the handle of a knife divide into end to end's grab handle and the handle of buckling, the handle one end of buckling is fixed with the tool bit, the other end with the rotatable fixed connection of grab handle.

Preferably, the relative rotation fixed angle of the bending handle and the grab handle is divided into three angles of 0 degrees, 30 degrees and 60 degrees.

Preferably, the length of the arc-shaped cutting edge is 10mm, the length of the back attached blade is 3mm, and the length of the knife handle is 20mm.

Preferably, the cutter head is made of stainless steel.

The utility model has the advantages of:

the two-way double-edged gingival knife can be pushed forwards or pulled backwards, can flexibly control the entry into the front inverted recess or the rear inverted recess, and is easy to cut gingiva and attach gingiva.

The back-attached blade is of a curve shape, can easily enter the inverted concave of the adjacent surface of the tooth, is tapered in a semi-peach shape and is very thin, and can enter the periodontal ligament to cut off the periodontal ligament when tooth extraction is performed, so that a dental elevator can easily enter to form minimally invasive tooth extraction when tooth extraction is performed; the blade can be used for removing subgingival calculus during periodontal surgery; when the periapical periodontitis surgical instrument is used for periapical periodontitis, the periapical periodontitis surgical instrument can enter a bone cavity of a surgical area to scratch, and soft tissues and granulation tissues inside the periapical periodontitis surgical instrument can be effectively removed.

The blade is divided into three types, namely a straight blade, a corner of 30 degrees and a corner of 60 degrees, so that the flexible operation of various angles of the blind area visual angle inverted concave area is convenient in clinical operation.

The blade is made of novel high-strength stainless steel, has very high hardness, does not have the swing of a disposable blade during operation, has stable and accurate hand feeling, is easy to cut tough and hard tissues such as cornified gums and the like, and can be repeatedly sterilized for use.

Fig. 1 is a schematic structural diagram of embodiment 1 of the present invention;

fig. 2 is a schematic structural diagram of the embodiment 2 of the present invention;

fig. 3 is a schematic structural view of another state of embodiment 2 of the present invention;

wherein, the knife comprises 1-arc-shaped knife edge, 2-back attached knife edge, 3-small arc-shaped knife edge, 4-arc-shaped groove, 5-knife handle, 6-grab handle and 7-bending handle.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. It should be noted that the terms "vertical", "upper", "lower", "horizontal", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only used for convenience in describing the present application and simplifying the description, but do not indicate or imply that the indicated device or element must have a specific orientation.

The utility model discloses an embodiment discloses a novel corner gum sword, including handle of a knife (5) and tool bit, specifically please refer to FIG. 1, the tool bit is the two-way cutting edge form of compriseing arc cutting edge (1) and back of the body attached cutting edge (2), and arc cutting edge (1) and back of the body attached cutting edge (2) are two-sided edge sharpening. The shape of the arc-shaped cutting edge (1) is similar to that of a conventional 15# blade, but the length of the cutting edge area is prolonged, the back attached cutting edge (2) is in a half peach shape and comprises a small arc-shaped cutting edge (3) and bevel edges on two sides, the bevel edge on one side is connected with the arc-shaped cutting edge, the bevel edge on the other side is bent inwards, and an arc-shaped groove (4) formed in the position, adjacent to the back attached cutting edge, of the knife handle forms a natural smooth curved surface.

For convenience of operation, the length of the arc-shaped cutting edge (1) is designed to be 10mm, the length of the back attaching blade (2) is designed to be 3mm, and the length of the knife handle (5) is designed to be 20mm.

In another embodiment, the knife handle is divided into a grab handle (6) and a bending handle (7) which are connected end to end, the grab handle is convenient for an operator to grab the knife body, one end of the bending handle is fixed with a knife head, the other end of the bending handle is fixedly connected with the grab handle in a rotating mode, the relative rotating fixed angle of the grab handle and the knife handle is divided into three types of 0 degree, 30 degrees and 60 degrees, namely three types of straight blades, 30 degrees of rotation angles and 60 degrees of rotation angles are formed, and the types are respectively shown in figures 1, 2 and 3, so that the knife handle can be selectively and flexibly operated according to specific conditions of various angles such as different blind area visual angles in clinical practice.

Finally, it should be noted that: the foregoing is illustrative of the preferred embodiments of the present invention, and is not to be construed as limiting the invention, and any modifications, equivalent alterations, improvements and the like made within the spirit and principle of the invention are intended to be included within the scope of the invention.
