Technical Field

The invention relates to the field of oral medical instruments, in particular to a novel gutta-percha point trimmer.

Background

In the root canal treatment, the cleaned, prepared root canal needs to be densely and three-dimensionally filled to eliminate dead space and prevent infiltration of external bacteria and contaminants, thereby preventing reinfection of the root canal system. In modern root canal filling technology, gutta-percha points are the most widely and mainstream root filling materials. Before filling, it is necessary to first select a gutta-percha point of an appropriate size according to the working length of the root canal of the patient and the size of the prepared root canal, and then to perform trimming to cut off the unnecessary portion.

In root canal filling, the ideal filling stop should coincide with the stop of the root canal preparation, typically at the physiological apical foramen or at the narrowest point of the apical apex. If the super-filling or the under-filling occurs, the effect of the root canal treatment will be affected. When overcharged, infectious agents such as bacteria are pushed into the apical foramen to cause periapical inflammation, and the root-filling material may cause foreign body reactions or toxic stimulation to periapical tissues. When the root canal is under-filled, periapical tissue fluid and exudate can seep back to the unfilled root canal, and the decomposition and propagation of the exudate can cause reinfection and failure of root canal therapy. Therefore, it is important to determine the length and taper dimensions of the gutta percha point prior to root filling.

At present, the existing gum point trimming tools in the market are various in types, and have various structural forms such as push-in type, push type and rotation type, but the using effect is not close to the human meaning, so that the user experience is poor.

Disclosure of Invention

The invention aims to provide a novel gutta-percha point trimmer, and aims to solve the technical problems that the using effect of the gutta-percha point trimmer in the prior art is not nearly satisfactory and the user experience is poor.

In order to achieve the purpose, the novel gutta-percha point trimmer adopted by the invention comprises a base, a sliding block component and a limiting piece, wherein at least one guide rail is arranged on the base, and positioning holes of different specifications penetrating through each guide rail and the base, wherein the sliding block assembly comprises a sliding block and a blade, the sliding block is in clearance fit with the base, the sliding block slides along the base, a counter bore and at least one sliding chute are arranged on the sliding block, the sliding groove is in clearance fit with the guide rail, the number of the blades is at least two, each blade is fixedly connected with the sliding block, and is positioned inside each sliding chute, and each sliding chute is provided with two blades, and the two blades are symmetrically arranged along the length extension direction of the guide rail, and the limiting parts are fixedly connected with the base and positioned at two ends of the base in the length extension direction.

Each positioning hole is provided with a guide cavity and a measuring cavity, the guide cavity is a cylindrical cavity, and the measuring cavity is a conical cavity.

Wherein each blade is made of stainless steel materials, and the thickness of each blade is 0.1-0.2 mm.

The slider is provided with X-shaped crossed chutes, the blades are fixedly connected with the chutes respectively, and the side surfaces of the cutting edges of the blades are tightly attached to the horizontal plane of the guide rail and form an included angle of 25 degrees with the horizontal plane of the guide rail.

And one end of the sliding block, which is far away from the guide rail, is arranged in a concave arc structure.

The sliding block assembly further comprises an elastic piece and a supporting piece, one end of the elastic piece is fixedly connected with the sliding block, the other end of the elastic piece is fixedly connected with the supporting piece, and the elastic piece and the supporting piece are both located in the counter bore.

The outer surface wall of the base is provided with aperture marks and scale grooves, the aperture marks are located on one sides of the positioning holes, each positioning hole corresponds to one aperture mark, and the scale grooves are located on one sides of the guide rails respectively.

The base is provided with one guide rail, the sliding block is provided with one sliding groove, the sliding groove is provided with two blades in an inclined mode, the sliding groove is in clearance fit with the guide rail, the positioning holes of different specifications are arranged in a straight line along the length extending direction of the base.

The base is provided with one guide rail, the sliding block is provided with one sliding groove, the sliding groove is provided with two blades in an inclined mode, the sliding groove is in clearance fit with the guide rail, the positioning holes of different specifications are divided into two groups, the two groups of positioning holes are arranged at the two ends of the base respectively, the two groups of positioning holes are arranged in a straight line along the length extending direction of the base, and a gap is reserved between the two groups of positioning holes.

The base is provided with two guide rails, the sliding block is provided with two sliding grooves, each sliding groove is provided with two blades, each sliding groove is in clearance fit with the corresponding guide rail, the positioning holes of different specifications are divided into two groups, and the two groups of positioning holes are arranged side by side along the width extending direction of the base.

The novel gutta-percha point trimmer has the beneficial effects that: the method comprises the following steps that a dentist selects a gutta-percha point needing to be trimmed, the size of a section needing to be trimmed is determined, the gutta-percha point is inserted into a positioning hole with a corresponding specification size in a rotating mode, then the sliding block is pushed by the hand and slides on the base, and then the blade cuts off the redundant part of the gutta-percha point, and the gutta-percha point with the required size is trimmed. The novel gutta-percha point trimmer is simple and convenient to operate and high in efficiency, the cutting section size of the gutta-percha point can be guaranteed to be accurate through the positioning holes with different specifications, and the blades are symmetrically arranged in the sliding grooves, so that on one hand, the bidirectional arbitrary cutting can be carried out along the base, on the other hand, the blade edges of the blades are not exposed, fingers can not touch the blades, and the gutta-percha point trimmer is safer and more reliable; in addition, the plane of the guide rail protrudes out of the plane of the base, so that the height of the guide rail is increased independently, the gutta-percha point is cut on the guide rail, unnecessary contact area of the blade can be reduced when the cutting is carried out, the blade can be enabled to be attached to the guide rail more tightly, and therefore the using effect of the novel gutta-percha point trimmer is improved, and the user experience feeling is better.
