Description

Technical Field

[0001] The utility model relates to a crown removal forceps for dental surgery and belongs to the technical field of medical instruments. Background Art

[0002] With the changes in modern human eating habits and maxillofacial bone development, the trend of incompatibility between human jaw bone mass and tooth mass has become increasingly prominent, which in turn causes the limited eruption space of mandibular third molars and the increasing incidence of mandibular third molars. Impacted wisdom teeth can cause local food impaction and caries of adjacent teeth; in addition, improper long-term local cleaning can easily cause local inflammation, leading to pericoronitis of wisdom teeth. In severe cases, it can cause severe multi-space infection in the maxillofacial region, threatening life. Therefore, the extraction of mandibular impacted third molars can effectively solve the complications related to impacted third molars. However, in clinical practice, some impacted teeth are located close to the inferior alveolar nerve, and even the roots penetrate into the inferior alveolar nerve canal. After surgery, it will cause permanent dysfunction of the inferior alveolar nerve, which is often manifested as numbness of the skin in the area innervated by the inferior alveolar nerve on the affected side, seriously affecting the quality of life of patients. Based on this, crowning of mandibular impacted third molars came into being. This technique refers to a method of cutting off the crown and retaining the residual root while keeping the tooth as immobile or slightly moving as possible. In recent years, a large number of studies in China have shown that this method can effectively protect the inferior alveolar nerve while effectively solving the complications caused by impacted third molars to patients. The essence of this technique is to minimally invasively and effectively cut off the crown and preserve the root. However, during the cutting process, due to the smooth surface of the crown and the irregular shape of the cut crown, it is often difficult to remove it because it is stuck between the root and the mesial second molar. At present, ordinary vascular forceps or dental tweezers are mostly used clinically to remove it. However, in practice, the clamping angle of ordinary vascular forceps and dental tweezers cannot meet the requirements, and the clamping tip strength is insufficient, so it is often impossible to remove the cut crown in one go, and it may even come out during the clamping process, causing accidental swallowing and serious complications.

[0003] Therefore, there is an urgent need in the art for a dental crown removal forceps that can efficiently and safely remove a cut and separated crown, prevent accidental falling off, reduce operation difficulty, save operation time, and improve intraoperative safety. Summary of the invention

[0004] The utility model aims to solve the problem that common vascular forceps or dental tweezers in the prior art often cannot remove the severed crown at one time, and even come off during the clamping process, causing accidental swallowing and forming serious complications.

[0005] In order to achieve the purpose of solving the above-mentioned problems, the technical solution adopted by the utility model is to provide a crown removal forceps for dental surgery, including a pair of forceps handles, the forceps handles are provided with locking forceps teeth for a pair of locking crown removal forceps, the ends of the two forceps handles are detachably provided with curved forceps beaks for firmly clamping the cut crown, and the middle parts of the two forceps handles are also provided with joints for opening and closing the crown removal forceps.

[0006] Preferably, the bending angle of the beak of the forceps is 45° or 90°.

[0007] Further preferably, the length of the curved portion of the beak of the forceps is 4 cm.

[0008] Further preferably, the tip of the forceps beak is a staggered sawtooth shape with a width of 3 mm.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] 1. The dental crown removal forceps of the utility model can remove the severed crown at one time, thereby preventing accidental falling off, reducing the difficulty of operation, saving operation time, and improving the safety during the operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to make the present invention more clearly understood, a preferred embodiment is described in detail with reference to the accompanying drawings as follows:

[0016] like Figure 1 , 2 As shown, the utility model provides a crown removal forceps for dental surgery. Before use, routine anesthesia, disinfection and draping are performed, and the flap is fully incised to expose the surgical area. After bone removal and cutting off the crown along the enamel-cementum junction, the locking forceps teeth 2 are separated, the forceps handles 1 are held, and the two forceps handles 1 are separated through the joint 3, and a suitable forceps beak 4 is selected, and the free crown is clamped by the tip of the forceps beak 4 to remove it.

[0017] The above is only a preferred embodiment of the utility model, and is not any formal or substantial limitation of the utility model. It should be pointed out that ordinary technicians in this technical field can make some improvements and supplements without departing from the utility model, and these improvements and supplements should also be regarded as the protection scope of the utility model. Any technician familiar with this profession can make some changes, modifications and equivalent changes made by using the technical content disclosed above without departing from the spirit and scope of the utility model, which are all equivalent embodiments of the utility model; at the same time, any changes, modifications and evolutions of any equivalent changes made to the above embodiments based on the essential technology of the utility model are still within the scope of the technical solution of the utility model.
