Description

Mirror surface drag hook for root tip operation

Technical Field

The utility model relates to the field of oral medical equipment, in particular to a mirror surface retractor for apical operation.

Background

Root canal therapy is a routine diagnosis and treatment in stomatology. Oral root canal therapy is an effective treatment for dental pulp apical disease. However, the root canal therapy has a certain failure rate, and for the affected tooth which fails to be treated by the root canal therapy, the treatment mode of root tip operation is often needed to retain the affected tooth. In the root tip operation, the flap needs to be cut open, and the flap is pulled by using a surgical retractor to obtain a good surgical visual field. Meanwhile, the root tip operation requires root tip excision, root tip reverse preparation, and root tip reverse filling. After the root tip is cut off, the cross section of the tooth root needs to be checked by using a microscope mouth mirror, and whether the tooth root is completely cut off is determined; the preparation and the inverted filling of the root tip need to be finished by using an ultrasonic working tip and an inverted filling device of the root tip after a position is found by using a microscope mouth mirror, and the problems of side penetration and non-tightness inverted filling of the inverted preparation hole type preparation can be easily caused because the root tip can not be directly viewed. The existing retractor for the root tip operation is usually made of stainless steel materials or resin materials, and as disclosed in the patent of the invention with the publication number of CN112353520A, the purpose of observing the cross section of a tooth root while pulling tissues can not be achieved. The root tip surgical retractor with the mirror surface, like the utility model patent with the publication number of CN209678713U, has the defects of low man-machine efficiency, easy reflection, dazzling and the like in the design.

Disclosure of Invention

The technical problem is solved: the problem that the existing root tip surgical retractor can not draw tissues and observe the cross section of a tooth root is solved, and the man-machine efficiency of the original root tip retractor with a mirror surface is improved.

The utility model discloses technical scheme as follows: the utility model provides a mirror surface drag hook for root tip operation, includes first drag hook head, second drag hook head and handle, the drag hook head outside is the mirror surface, and the drag hook remainder is the rough surface, the handle both ends are two drag hook heads, and drag hook head plane and handle plane within a definite time become 90 degrees angles.

Furthermore, the two hook heads are one big and one small.

Preferably, the mirror surface retractor for the root tip operation is integrally formed by bending stainless steel.

Preferably, the hook head is trapezoidal with round and blunt corners.

Preferably, the hook rough surface is a wire-drawn, frosted or matte surface.

The utility model has the advantages that: the mirror surface drag hook for the apical operation of the utility model can observe the cross section of the tooth root when the traction tissue is in the traction tissue, is not easy to reflect light and dazzle, is easy to grip simultaneously, and improves the man-machine work efficiency.

Drawings

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

Fig. 2 is a side view of the present invention.

In the figure: 1-first hook head, 2-second hook head, 3-handle, 4-mirror surface and 5-rough surface.

Detailed Description

The present invention will be further explained with reference to the drawings and examples. The described embodiments are only some, but not all embodiments of the invention. Based on the embodiment in the utility model provides a, this technical field ordinary skilled person does not make other embodiments that the creative work prerequisite obtained, all belong to the utility model discloses the scope of protection.

Example (b): referring to fig. 1 and 2, a mirror surface retractor for a root tip operation comprises a first retractor head 1, a second retractor head 2 and a handle 3, wherein the outer side of the retractor head is a mirror surface 4, the rest part of the retractor is a rough surface 5, the two ends of the handle 3 are the first retractor head 1 and the second retractor head 2, a 90-degree angle is formed between the plane of the retractor head and the plane of the handle 2, during use, the retractor head at one end is used for traction, and the other retractor head plays a role in skid resistance. The first draw hook head 1 is a big draw hook head, and the second draw hook head 2 is a small draw hook head. When the front teeth are used, the front teeth have no mouth angle blocking, the large pull hook head 1 can be used for traction to obtain the maximum visual field, the rear teeth have mouth angle blocking, and the small pull hook head 1 can be used for reducing the traction resistance and reducing the tissue damage. Preferably, the mirror surface retractor for the root tip operation is formed by bending a stainless steel integrally, a mirror surface is formed by precisely polishing the outside of the retractor head, the retractor head is in a trapezoid shape with a blunt corner, the rest surfaces of the retractor are rough surfaces, and the rough surfaces are wire drawing, frosting or matte surfaces.

The utility model discloses during the use, select suitable draw hook head according to the tooth position, the first draw hook head 1 of big draw hook head is selected to the anterior tooth, little draw hook head second draw hook head 2 is selected to the posterior tooth, turn over behind the lamella and pull tissue lamella and lip with the draw hook head, handle 3 holds the method is, the handle 3 outside is pinned to the thumb, the fist gripping handle 3 is drawn together to the four fingers, the little finger is near another draw hook head, so gripping antiskid and laborsaving, the root cross-section can be observed in draw hook head outside mirror surface to the tractive simultaneously, because the handle surface is the rough surface, can not reflect microscope lamp or dental chair light, be difficult to the reflection of light and dazzle.

It should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the same, and although the present invention is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced equally, and these modifications or equivalent replacements cannot make the modified technical solutions depart from the technical solution scope of the present invention.
