Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are exemplary only for explaining the present invention, and should not be construed as limiting the present invention.

In the present invention, unless otherwise explicitly specified or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly, e.g., as being fixedly connected, detachably connected, or integrated; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood according to specific situations by those of ordinary skill in the art.

Examples

Referring to fig. 1, in the present embodiment, a periosteal detacher is provided, which includes a handle 1 and a detaching head 2 disposed on the handle 1.

As shown in fig. 1 and 2, a neck portion 3 is provided at the left end of the handle 1, and the peeling head 2 is provided on the neck portion 3. Handle 1, neck 3 and peel off head 2 three formula structures as an organic whole, wherein, can use whole root stainless steel cylinder or other corrosion-resistant and material that accords with medical standard as the raw materials, through corresponding technology with handle 1, neck 3 and peel off head 2 three machine-shaping. In order to avoid the problem that the surface of the handle 1 is too smooth to affect the holding, anti-slip lines can be arranged on the handle 1 when the handle 1 is processed.

As shown in fig. 1 and 3, the end of the stripping head 2 remote from the handle 1 is provided with a sharp projection 4. Wherein, handle 1, neck 3, peel off head 2 and bellying 4 four formula structures as an organic whole, so, can guarantee the reliability of connecting between each component to reduce the fracture possibility of appearing between the component that links to each other.

As shown in fig. 3 and 4, the cross section of the boss 4 gradually increases from the tip end to the tail end of the boss 4, wherein the boss 4 includes three cutting edges 7, and the three cutting edges 7 intersect at the tip end of the boss 4.

In the present embodiment, the shape of the boss 4 is a triangular pyramid.

As shown in fig. 4, in order to adapt to the structure of the cementum surface, the protrusion 4 may have a curved triangular pyramid shape in which each cutting edge 7 has a curvature.

To avoid the tip of the protruding part 4 being too sharp to stab soft tissue or the like, the tip of the protruding part 4 may be subjected to a blunt treatment. For example, the tip of the projection 4 may be provided with a spherical structure, wherein the radius of the spherical structure is not more than 0.01cm. It is noted that the figures do not clearly show the spherical structure at the tip of the boss 4 due to the size.

The procedure for stripping the periosteum from the teeth is roughly as follows:

cutting the periosteum at the corresponding position through a scalpel and forming a wound;

holding the handle 1 of the periosteal detacher, aligning the boss 4 with the wound and inserting the boss into the wound;

the handle 1 is moved, the convex part 4 further penetrates into the wound, wherein the cutting edge 7 can strip the periosteum in the deep part along with the penetration of the convex part 4, and meanwhile, the stripping head 2 of the periosteum stripper also enters the wound;

the handle 1 is operated, and periosteum stripping work is completed through the stripping head 2.

When performing periosteal dissection, the sharp projection 4 can be inserted into the periosteum and enter a deeper position in the periosteum only by cutting a small-sized wound on the periosteum, and the wound caused by periosteal dissection can be effectively reduced. In addition, the sharp convex part 4 can be used for accurately positioning the position to be stripped, thereby avoiding influencing other parts, and further reducing the trauma.

The periosteum stripper completes periosteum stripping work through the stripping head 2. As shown in FIG. 3, the peeling head 2 comprises a peeling surface 5, the peeling surface 5 is a smooth and convex arc surface, wherein the convex part 4 is positioned on the peeling surface 5, and the tail end of the convex part 4 is connected with the peeling surface 5.

Further, the stripping head 2 also comprises an inner concave surface 6, the inner concave surface 6 is a smooth arc surface, and the edges of the inner concave surface 6 and the stripping surface 5 are connected. Wherein the thickness of the peeling head 2 can be reduced by providing the inner concave surface 6.

In order to make the transition between the stripping head 2 and the bulge 4 smoother, the bulge 4 may comprise a curved surface 8, wherein the curved surface 8 is connected and tangent to the inner concave surface 6.

The convex portion 4 has three cutting edges 7, wherein two cutting edges 7 are respectively located at two sides of the curved surface 8, and the other cutting edge 7 is located at the back side of the curved surface 8. In the present embodiment, the cutting edge 7 on the back side of the curved surface 8 is tangent to the peeling surface 5, also for the purpose of improving the smoothness between the convex portion 4 and the peeling head 2.

The size of the peeling head 2 is larger than that of the convex part 4, so when the peeling head 2 enters into the periosteum to perform peeling work, the wound is expanded by the peeling head 2.

In order to reduce the damage to periosteum, soft tissues and the like, the peeling head 2 can be subjected to blunt treatment, so that the peeling head 2 is subjected to blunt peeling when being peeled, the damage to the periosteum, the soft tissues and the like is reduced, and the postoperative recovery is facilitated.

In this embodiment, the junction of the concave inner surface 6 and the stripping surface 5 may be provided with a rounded chamfer, thereby dulling the stripping head 2 and making the overall profile of the stripping head 2 smoother.
