A dental robot includes a platform and a suspension system. The suspension system supports the platform and automatically compensates for weights of the platform and a robot arm, end effector, and tooth clamp attached to the platform. The suspension system maintains a constant height of the platform above a base, absent an external force on the tooth clamp. The suspension system allows position and orientation of the platform to change with three degrees of positional freedom and three degrees of rotational freedom, relative to the base, in response to an external force on the tooth clamp, such as a result of movement (change in position and / or orientation) of a subject. A rigid connection between the tooth clamp and the platform ensures that position and orientation of the platform remains fixed, relative to the subject's teeth, in response to movement of the teeth.

A dental robot includes a platform and a suspension system. The suspension system supports the platform and automatically compensates for weights of the platform and a robot arm, end effector, and tooth clamp attached to the platform. The suspension system maintains a constant height of the platform above a base, absent an external force on the tooth clamp. The suspension system allows position and orientation of the platform to change, relative to the base, in response to an external force on the tooth clamp greater than about 0.1 N, such as a result of movement (change in position and / or orientation) of a subject. Consequently, the position and orientation of the platform remain fixed, relative to the subject's teeth, in response to movement of the teeth.

The present invention relates to dental tweezers. More specifically, the dental tweezers comprise: a forceps unit (11) composed of a combination of a pair of forceps; and a gripping unit (21) which is set on the outer surface of each of the forceps and adjusts the distance between the forceps, the dental tweezers further including twisting prevention units (14, 15) which are arranged offset from each other on the pair of forceps, and which guide the pair of forceps to prevent the respective opposing forceps from twisting and enable the forceps to mate when the pair of forceps approach each other closely.

Tweezers for use in conducting root canal therapy and methods of conducting root canal therapy using the tweezers are described, the tweezers including: a pair of elongate arms; the arms are moveable between a closed condition and an open condition and are biased towards the closed condition; a grasping formation is provided at the end of each of the arms; the grasping formations have substantially part cylindrical faces to grasp opposite sides of a substantially cylindrical item; and wherein the axes of the cylindrical faces are offset from a direction perpendicular to the length of the arms.

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.

An oral care device relates to the technical field of oral care and comprises a hollow elastic handle of a tweezers-shaped structure, the elastic handle comprises a holding portion and two tweezers arms, a first water pumping opening and a through hole communicated with an inner cavity of the elastic handle are formed in the end of the holding portion, and a pressing portion is arranged on the lower portion of the middle of the elastic handle. A water injection pipe is arranged in the elastic handle; the tail ends of the two tweezers arms are fixedly connected with tweezers heads, sawtooth anti-skid textures are arranged on the occlusal surfaces of the tweezers heads, silica gel bristles are arranged on the other three surfaces of the tweezers heads, and the tweezers heads are provided with water outlets and second water pumping ports; one end of the water injection pipe extending into the elastic handle is fixedly connected with the water outlet, and the other end penetrates through the through hole and is connected with the water injection device. The tweezers and the silica gel brush head are integrally designed, the silica gel tweezers replace metal materials, the multifunctional toothbrush is suitable for multi-scene requirements of tooth cleaning, medicine smearing, dressing clamping and the like, foreign body sensation is reduced, the holding comfort is improved through the lightweight design and the anti-slip handle, the risk of multi-tool switching is avoided, and the probability of misoperation injury is reduced.
