The invention provides dental forceps with a depth limiting baffle, and relates to the technical field of medical instruments, the dental forceps comprise working assemblies and a depth control assembly, the two working assemblies intersect and are rotatably connected to form a rotating joint, and the rotating joint is connected with the depth control assembly; the depth control assembly at least comprises an adjusting knob and a limiting baffle connected with the adjusting knob, the height of the limiting baffle is adjusted through rotation of the adjusting knob, and the adjusting knob is connected to one side of the rotating joint. The working assembly comprises forceps beaks and handles, and the adjusting knob and the limiting baffle are both located between the two handles. An adjusting gear is connected to the end, close to the rotating joint, of the limiting baffle and movably connected with the adjusting knob. Limiting lugs are connected to the side portions of the rotating joints, and an adjusting gear is connected between the two limiting lugs. The problems that in the prior art, the dental forceps cannot effectively control the insertion depth of the forceps beak and are poor in universality are solved.

A peptide composed of an amino acid sequence of the following General Formula 1: K—Y-R1-R2-R3-R4-R5-R6-R7-R8 (General Formula 1), a composition containing the peptide, and uses thereof are disclosed. In General Formula 1, R1 is arginine (R), lysine (K), or glutamine (Q); R2 is arginine (R) or glutamine (Q); R3, R4, and R5 are each arginine (R) or lysine (K); R6 is asparagine (N) or serine (S); and R7 and R8 are lysine (K) or tyrosine (Y). The composition is applied to the treatment of damaged dentin, such as dental caries or fractures, and thus can prevent possible dentin necrosis, dental extraction, or dental loss after treatment.

The invention discloses a multi-parameter analysis-based maxillary first molar extraction operation type decision-making method and a multi-parameter analysis-based maxillary first molar extraction operation type decision-making system. The method comprises the steps of firstly obtaining patient age and oral panorama; secondly, segmenting the panoramic film through a trained DeepLabV3 + semantic segmentation model, and extracting a mesio-middle cheek root outer side edge, a mesio-middle cheek root inner side edge, a mesio-middle cheek root outer side edge, a mesio-middle cheek root inner side edge and a root bifurcation point; calculating a tooth root minimum curvature radius R, a root bifurcation included angle theta and a local standardized bone mineral density index D based on the extracted contour; and finally, entering a preset hierarchical decision engine according to the age of the patient, automatically outputting an operation form of suggesting overall extraction or root extraction in combination with the quantization parameter, and generating a decision basis and a quantization parameter report. According to the method, deep learning feature extraction and a clinical rule engine are combined, objective quantitative decision making and personalized recommendation of a tooth extraction operation are realized, and the accuracy and interpretability of decision making are improved.

This utility model discloses a replaceable sponge-headed toothbrush after tooth extraction, including a handle, a brush head, and bristles. The brush head is provided with bristles, and a U-shaped groove is formed at the end of the brush head away from the handle. A replaceable sponge cleaning pad is installed in the U-shaped groove, and the replaceable sponge cleaning pad has a U-shaped structure that is interference-fitted with the U-shaped groove. Side limit blocks are provided on both sides of the brush head, and front limit strips are provided at the top and bottom of the front end of the brush head. This replaceable sponge-headed toothbrush after tooth extraction avoids direct contact between the brush bristles and the wound by adding a replaceable sponge cleaning pad to the brush head, reducing the patient's fear. The sponge cleaning pad is made of medical-grade hemostatic sponge, which avoids bleeding and tearing caused by secondary contact of the toothbrush with the wound. The "replaceable" design ensures that the sponge pad can be replaced after use or periodically to maintain the hygiene of the toothbrush. It is easy to clean after use, and the openings in the side limit blocks make it easier to shake off water accumulated in the stabilized part by swinging the toothbrush.

This invention discloses a manual negative pressure saliva aspirator after tooth extraction, comprising: a mouth-holding structure and a negative pressure generating element; the mouth-holding structure includes an arc-shaped support base and a flexible suction element, the arc-shaped support base being for holding in the mouth, one end of the flexible suction element being located on the arc-shaped support base, and the other end of the flexible suction element extending along the direction of gravity and used to absorb saliva in the oral cavity; the negative pressure generating element is connected to the flexible suction element through a flow guiding structure and is used to aspirate saliva within the flexible suction element through negative pressure. The patient manually operates the negative pressure generating element to generate negative pressure, which is transmitted through the flow guiding structure to the closed cavity inside the flexible suction element, thereby aspirating the saliva absorbed by the flexible suction element and exiting it from the oral cavity. Throughout the aspiration process, the negative pressure is transmitted through direct contact between the flexible suction element and the saliva, rather than through atmospheric pressure within the oral cavity acting on the wound surface. Therefore, while effectively absorbing saliva, it avoids pulling on the wound due to negative pressure, thus preventing damage to the protective blood clot.

The invention belongs to the technical field of medical instruments, and particularly relates to a dental extraction auxiliary device which comprises a box body, a supporting plate is slidably connected to the box body and used for supporting the head of a patient, an elastic part is arranged between the supporting plate and the box body, clamping mechanisms are arranged on the two sides of the box body and used for clamping the face of the patient, and the clamping mechanisms are arranged on the box body and used for clamping the face of the patient. A forehead restraining assembly is arranged at the end, away from the neck of the patient, of the box body and used for restraining the forehead of the patient, a transmission assembly is arranged on the supporting plate, the supporting plate is in transmission fit with the forehead restraining assembly through the transmission assembly, and a mouth shape amplifying mechanism is arranged on the box body and used for controlling the opening degree of the mouth of the patient. A fixing mechanism is arranged at the bottom of the box body, and the box body and the treatment chair are installed and fixed through the fixing mechanism. Omnibearing stability of the head of a patient can be ensured; the mouth opening degree of the patient can be controlled, the working efficiency is improved, and the tooth extraction operation time is shortened.
