Description

TECHNICAL FIELD

[0001] The utility model relates to a tooth forceps, particularly to an adjustable tooth forceps. BACKGROUND

[0002] At present, tooth forceps as a common tool in oral medical instruments, its main function is to realize the extraction of teeth by clamping teeth with the forceps head. However, the tooth forceps in the prior art has the following technical limitations, resulting in low efficiency and flexibility:

[0003] The clamping area of the forceps head of the existing tooth forceps is fixed and cannot be adjusted according to the width of the teeth. This design brings some disadvantages:

[0004] When the clamping area of the forceps head is too wide, it is easy to cause additional compression to the tissues around the teeth, increase the discomfort of the patient, and may cause the teeth to be clamped insecurely, affecting the tooth extraction effect;

[0005] When the clamping area of the forceps head is too narrow, the clamping force is concentrated on some points of the teeth, which is easy to cause damage to the surface of the teeth, especially to the fragile or damaged teeth, which may cause them to break during the extraction process, increasing the operation difficulty. Since the clamping area of the forceps head cannot be adjusted according to the width of the teeth, the applicability of the existing tooth forceps is poor, and it cannot efficiently meet the tooth extraction needs of different teeth.

[0006] The forceps head and the forceps body of the existing tooth forceps are usually designed as a fixed integral type, and the angle and the length of the forceps head relative to the forceps body are not adjustable. This design has the following problems:

[0007] In order to adapt to the tooth extraction operation of teeth in different positions, such as incisors, molars or wisdom teeth, the space and direction of the teeth are different, and the angle of the fixed forceps head often cannot meet the actual needs. Therefore, it is usually necessary to prepare multiple tooth forceps with different angles to adapt to various tooth extraction angles, increasing the operation burden and cost of the doctor.

[0008] For deep teeth, especially the posterior teeth area, the forceps head of the existing tooth forceps is often too short to be inserted into the interior to effectively clamp the teeth for tooth extraction, which further limits the use range of the tool.

[0009] The above problems result in that the existing tooth forceps are not flexible and have poor applicability in actual use, and the doctor needs to frequently change tools to complete the extraction of teeth in different positions, increasing the operation time and complexity.
