The pair of adjustable dental forceps comprises a first forceps body and a second forceps body, the middle positions of the first forceps body and the second forceps body are hinged, and the tail ends of the first forceps body and the second forceps body form an operating end; the pliers further comprise pliers heads, the pliers heads are installed at the head positions of the first pliers body and the second pliers body in a telescopic rotating mode, and each pliers head can be stretched relative to the pliers body or the working angle can be adjusted; and the spacing-adjustable contact head is arranged on the contact surface of the forceps head and the teeth, and the contact surface is adjusted according to the size of the teeth. According to the utility model, the clamping area of the forceps head can be adjusted according to the width of teeth, and the angle and extension length of the forceps head relative to the forceps body can be adjusted, so that the flexibility and efficiency of tooth extraction operation are obviously improved.

This utility model discloses a self-locking oral forceps, including a first clamping arm and a second clamping arm fixedly connected at their tail ends, with a self-locking assembly between the first and second clamping arms. The self-locking assembly includes a support rod, an adjusting roller, and a locking nut. The adjusting roller is fixedly installed in the middle of the support rod and coaxially arranged with it. The first and second clamping arms have interconnected support through holes and limiting strip holes. Both ends of the support rod pass through the support through holes and limiting strip holes in sequence, extending to the outside of the first and second clamping arms and connecting with the locking nut. The locking nut has a limiting block that matches the limiting strip hole. Both ends of the support rod are machined with external threads in opposite directions. The inner walls of the inner holes of a pair of fixing nuts are machined with internal threads that match the external threads at the corresponding ends of the support rods. The structure of the self-locking assembly of this utility model allows for flexible adjustment of the tightness of the clamped object, saving time and effort during operation.

This utility model discloses a non-slip tooth extraction forceps with a beak-like, gecko-foot-inspired design. The forceps includes a first and a second lever, rotatably connected by a pin. Both the first and second levers have reinforcing components at their working ends. These reinforcing components include a mounting platform, a bristle base platform, and a fiber surface strip. The mounting platform is fixed to the surface of the first and second levers. One end of the bristle base platform is connected to the mounting platform, and the other end is connected to the fiber surface strip, forming a multi-level biomimetic adhesion structure. This application combines a gecko foot structure with tooth extraction forceps. The multi-level bristle structure achieves high-strength dry adhesion through van der Waals forces, and the mechanical mechanism of "tangential force triggering normal adhesion" perfectly matches the "grip first, then pull" action sequence in tooth extraction, increasing friction at the beak-tooth interface, significantly reducing surgical time, solving the problem of easy slippage of the forceps during tooth extraction, and significantly improving operational efficiency.

The utility model belongs to the technical field of dental forceps, and particularly relates to an oral cavity dental forceps sleeve which comprises dental forceps, a forceps head is fixedly connected to the end of the dental forceps, a forceps sleeve is connected to the outer side of the forceps head in a sleeved mode, an installation opening is formed in the edge of the top face of the forceps sleeve, a fixing band is connected to the outer side of the top of the installation opening in a sleeved mode, and a limiting groove is formed in the top face of the forceps sleeve. A mounting groove is formed in the bottom surface of the clamp sleeve, a clamping sleeve is inserted into the inner side of the mounting groove, and the two ends of the clamping sleeve are located on the two sides of the clamp sleeve. Through the arrangement of the forceps sleeve, the clamping sleeve and the fixing band, the forceps sleeve is sleeved on the outer side of the forceps head of the dental forceps, and the forceps sleeve can be made of resin materials, so that the forceps head can be well protected, the forceps sleeves with various shapes can be prepared in advance, the forceps sleeves with different shapes can be selected according to the tooth extraction requirements of medical personnel, the convenience of a tooth extraction operation is improved, and the operation is convenient. And compared with the preparation of a plurality of dental forceps, the use cost is reduced, and the arrangement is convenient.

The manufacturing method comprises the following steps: constructing a to-be-scanned area of a to-be-extracted tooth, and obtaining a first three-dimensional model based on the to-be-scanned area; selecting the model of the dental forceps main body according to the tooth position of the to-be-extracted tooth, and obtaining a second three-dimensional model corresponding to the dental forceps main body; constructing a first forceps head clamping part completely matched with the to-be-extracted tooth at the position of the to-be-extracted tooth in the first three-dimensional model, and obtaining a third three-dimensional model corresponding to the first forceps head clamping part; carrying out three-dimensional model splicing on the second three-dimensional model and the third three-dimensional model, and smoothing the joints of the models to obtain a fourth three-dimensional model; and generating a second forceps head clamping part based on a preset entity generation technology and the fourth three-dimensional model, and obtaining the personalized dental forceps based on the second forceps head clamping part and the dental forceps main body. According to the invention, personalized customization of the dental forceps is realized according to different tooth forms, the tooth extraction reliability is improved, and the tissue injury risk is reduced.
