Dental forceps

Technical Field

The utility model relates to a medical instrument for department of stomatology, concretely relates to tweezers for dentistry.

Background

Tweezers, one of the most commonly used medical instruments in stomatology, are mainly used for holding cotton balls, small instruments and suturing to check tooth looseness, and play a considerable role in the field of dental medicine. In addition to holding the above-mentioned oral general articles, another particular use of forceps in dentistry is: the teeth are clamped. However, due to the particularity of the tooth tissue, irregular shape, different sizes, hard and smooth tooth bodies and the like, the risks of unstable clamping, sideslip, falling off and the like are easy to occur in the operation process. In the related scientific research of oral cavity, the isolated tooth is often required to be collected, and the isolated tooth is used for extracting related tissues and cells to carry out scientific experiments, so that the clamping of the tooth body tissues is particularly important. Including from clinical collection to laboratory use, a stable gripping tool is needed. However, the existing clamping instruments such as tweezers are easy to slip off, so that the tissue sample is polluted, inconvenience is brought to the experiment operation, and the smooth development of the experiment is influenced. In addition, in some clinical operation processes, for example, in the process of autologous tooth transplantation, a doctor needs to tightly clamp teeth, and the teeth are transplanted to a corresponding implanted area, so that the teeth cannot slip off or touch a non-implanted area, otherwise, the teeth are polluted, and the transplantation result is influenced.

Patent application CN212853679U discloses tweezers for oral diagnosis and treatment, including the body, body one end cross swing joint, the other one end fixed connection of body, body swing joint's one end is equipped with plug portion, is equipped with the anticreep friction strip in the plug portion, and plug portion has cup jointed and has made a diagnosis and treat the head, and it has a plurality of inspection function through plug portion with different head combinations of diagnosing, but does not consider the stability when the tweezers have the agreeing with of tooth and centre gripping tooth in the use.

Disclosure of Invention

The groove depth of the antiskid groove 3.2 is 0.02-0.08 mm.

The middle sections of the elastic forceps handles 1 are mutually crossed, and anti-slip threads 2 are arranged on the outer sides of the elastic forceps handles 1 and above the crossed positions.

The anti-slip grooves 3.2 are in a reticulate pattern.

Compared with the prior art, the utility model discloses following technological effect has:

1. the 3.1 inboard tooth contact surface of cambered surface structure sets up according to the tooth body tissue appearance, laminates with the tooth appearance, has increased moreover with tooth area of contact to increase the frictional force between tooth and the tooth contact surface, take place the sideslip when effectively preventing the centre gripping tooth, the degree of agreeing with is good, and stability is good. Cambered surface structure 3.1 is network structure's anti-skidding insection, has increased the degree of agreeing with of tweezers and tooth shape on the one hand, has increased area of contact, and on the other hand has better anti-skidding effect.

2. Through the design of the depth of the anti-skidding groove 3.2 and the width of the cambered surface structure 3.1, the impurities are prevented from being attached, the residual impurities in the tooth grooves are easier to clean, and the service life of the tweezers is prolonged.

3. Tiny centre gripping is most advanced 3.3, can be used to other tiny apparatus of centre gripping and articles for use, increases the utility model discloses a functionality not only is used for centre gripping tooth body tissue, still has the general function of traditional tweezers, realizes the multi-functionalization.

4. The crossed reverse forceps design can naturally clamp teeth or other articles in the process of releasing the forceps handle by an operator, the operation is convenient and labor-saving, and the stability is good.

5. The connecting line at the two ends of the cambered surface structure 3.1 and the forceps handle 1 form an included angle of 140-160 degrees, so that the visual field is fully exposed, and the operation is more convenient and accurate.
