Description
Technical Field
The utility model relates to a tooth residual tooth extracting forceps, and belongs to the field of oral surgical medical appliances.
Background
The clinical tooth extraction operation can be carried out under the condition that serious malnutrition and caries are already caused when the tooth is required to be extracted. For the situation that the tooth with the seriously incomplete appearance is pulled out, the situation that the clamping contact surface cannot be clamped or the clamping is unstable is often difficult to find on the seriously defective decayed tooth in the tooth pulling process of the traditional tooth pulling forceps, because the tooth is pulled out mainly through the cambered surface of the inner side of the jaw to clamp the crown cambered surface when the traditional tooth pulling forceps clamp the tooth, but when the situation that the appearance of the cambered surface of the tooth is seriously damaged is encountered, the problem that the concave of the jaw of the tooth pulling forceps is difficult to find the acting point on the appearance of the severely damaged tooth with the incomplete appearance or the found acting point is poor in stability is caused, and further slipping easily occurs when the tooth is pulled out or the situation that the residual tooth is clamped and broken because the clamping force is stably increased is caused, so that the operation efficiency and the operation safety are seriously influenced.
In addition, because the appearance and the tooth surface radian of adult teeth and children teeth and each tooth position tooth in the oral cavity all have great difference, in order to deal with the appearance and the surface arc of the teeth of adult, children, guarantee to realize stable centre gripping, traditional tooth extraction pliers have to design the tooth extraction pliers of the multiple model of head and the different angles of pincers leg, the model specification reaches twenty kinds more, the apparatus use cost is high, need carefully select in clinical tooth extraction in addition and just can select suitable model, have influenced operation efficiency.
Disclosure of Invention
The utility model aims to solve the technical problems that: overcomes the defects in the prior art, and provides the tooth forceps for extracting the residual teeth, which can accurately clamp the residual teeth at four points, clamp the residual teeth stably and fixedly, and can realize the positioning and clamping of the residual teeth with various shapes by reducing the contact area.
The utility model relates to a tooth residual tooth dental forceps which comprises two forceps bodies connected through a hinge shaft, wherein the parts of the forceps bodies positioned at the front part of the hinge shaft are forceps beaks, the rear parts of the forceps bodies are forceps handles, the clamping surfaces of the front end clamping sections of the two forceps beaks are concave arc surfaces, the front parts of the clamping surfaces are provided with grooves which extend to the front end surfaces of the forceps bodies and form two positioning clamping points on the front end surfaces of the forceps bodies; in the closed state, a space exists between the front ends of the beaks of the two pincers (namely, the front ends of the beaks of the two pincers are not closed).
The tooth forceps designed by the utility model adopts a completely different positioning and clamping principle from the traditional tooth forceps, the grooves on the clamping surfaces at the front ends of the two forceps beaks and the front end surfaces of the corresponding forceps bodies form four positioning and clamping points, and the contact area between the forceps beaks and the residual teeth is reduced through four-point positioning and clamping, so that the positioning and clamping of the residual teeth with different shapes in the oral cavity of adults and children are realized, the clamping stability is ensured, and the tooth forceps are favorable for removing the residual teeth. Through the structural design, on one hand, the preparation of the tooth forceps is reduced, the operation flow is optimized, and on the other hand, the clinical model selection difficulty and the instrument use cost are greatly reduced, and the economic benefit is outstanding.
Preferably, the width of the groove gradually increases from the back to the front, namely from the rear end of the clamping surface to the front end, and the width of the groove gradually increases, so that the front end of the beak of the pliers can be effectively ensured to form a clamping fixing point, and four-point positioning is realized.
Preferably, the thickness of the beak is gradually reduced from back to front. The thickness of the front end of the forceps beak is thinner, so that the front end of the forceps beak can better enter into the gap between the gum and the teeth during clamping, and the teeth can be clamped stably from the root.
Preferably, the hand-held part of the forceps handle is provided with a handle flower so as to increase the friction force between the hand and the forceps handle, prevent the forceps body from slipping, and reduce the damage probability to adjacent teeth and soft tissues in operation.
Preferably, the lip teeth are arranged on the front end clamping surface of the beak clamping section, so that friction force is increased, and the beak clamping section is more stable when clamping residual teeth.
In addition, the surfaces of the forceps handles and the forceps beaks can be brushed, so that corrosion is reduced, and the service life of the tooth-residual tooth forceps is prolonged; the outer side surface of the clamp handle can be arc-shaped, so that an operator can feel comfortable when holding the clamp body.
