A dental instrument having a working end that can be easily rotated into a desired position in the mouth of a patient while the handle of the instrument is held steady by the user. The dental instrument has a handle and a working end that is rotatably coupled together by a rotational joint formed by a housing having a cavity and a member positioned in the cavity so that the housing and the member are free to rotate relative to each other. The housing may include one or more finger rests for easy manipulation. The rotational joint may be connected to the handle via a bend so that the working end extends, obliquely relative to the handle. The working end may be a cord packer, a Woodson end, a periotome end, and a periosteal end. The instrument may be formed from an autoclavable, disposable, plastic or other medical grade material.

The bone chisel comprises a chisel head and a chisel body, a bending part is arranged at the end of the chisel body, and the chisel head is detachably arranged at the other end of the bending part through a connecting piece. The bone chisel has the effect of reducing the use cost and replacement cost of the bone chisel.

The application discloses a multifunctional ultrasonic dental elevator special for maxillary third molar root extraction, which comprises a working end, a joint part connected with the working end, and a handle end connected with the joint part; the working end comprises a blade slidingly arranged on the working end, a plurality of elastic members connected with the blade, a plurality of fixing plates connected with the elastic members, and a pulley connected with the bottom of the blade; the blade is connected with the pulley through a plurality of connecting lines; the joint part comprises an upper joint part connected with the working end and a lower joint part; and the handle end comprises a central control system, a blade adjusting button, a water quantity adjusting button, an illumination intensity button, a suction pipe adjusting button and a photographing emergency stop button connected with the central control system. The multifunctional ultrasonic dental elevator integrates multiple functions, avoids the replacement of different instruments during tooth extraction, greatly saves tooth extraction time, and improves the use efficiency and use range of the dental elevator.

The present invention provides a paste syringe that is designed to release, as much as possible, internal pressure generated inside a syringe body when a paste is subjected to pressure, thereby avoiding paste solidification or liquid seepage due to residual pressure, and accordingly avoiding difficulty in forward movement of an extrusion member. The paste syringe includes a syringe body, a nut member, a screw member, an extrusion member, and a closure member. The syringe body has a cylindrical inner periphery and includes a main section in which a paste is stored. The nut member is located at a base end of the main section of the syringe body such that the nut member and the main section are concentric, and has a cylindrical inner periphery on which a female thread is formed. The screw member includes a male thread section with a male thread formed on its cylindrical outer periphery, and an operation section located at the rear of the male thread section, and is allowed to move forward within the main section of the syringe body while being rotated in a direction of forward movement with the male thread being screwed into the female thread of the nut member. The extrusion member is located at a tip of the screw member. The closure member is detachably attached to a tip part of the syringe body to close a discharge orifice of the syringe body. The extrusion member includes a disc-shaped portion with an outer diameter corresponding to an inner diameter of the main section of the syringe body, and has a residual pressure-release space is provided behind the disc-shaped portion, and the disc-shaped portion includes at least one through hole that communicates with the residual pressure-release space.

Torque wrench (1) for connecting a replaceable instrument tip (20) to a hand piece that carries the replaceable instrument tip (20) in operation, comprising - a base element (2) having a receiving region (15) for placing the instrument tip inside the receiving region (15) at least during connecting the instrument tip (20) to the hand piece, - a torque wrench mechanism for applying a certain torque when connecting the instrument tip (20) to the hand piece and - a housing (10) surrounding the instrument tip (20) being arranged in the receiving region (15), the housing being preferably transparent, -- wherein the torque wrench (1) has a guiding structure (4) for aligning the torque wrench (1) relative to the hand piece during arranging the torque wrench (1) on the hand piece, in particular in an interface region of the hand piece, and / or -- wherein the housing (10) has an inner surface (11) and an outer surface (12) being concentric to each other over a complete primary region (31) extending at least from the base element (2) to the end (25) of the instrument tip (20), when the torque wrench (1) is equipped with the instrument tip (20).

This invention discloses a tool kit for extracting horizontally impacted wisdom teeth, belonging to the field of medical device technology, to solve the problem of difficult wisdom tooth extraction in the prior art. The tool kit for extracting horizontally impacted wisdom teeth includes a connecting pin (1), a support base (2), and a dental elevator (3). The connecting pin (1) can be connected and fixed to the impacted wisdom tooth (6), and the support base (2) can be matched and connected to the buccal alveolar bone surface (7). The dental elevator (3) can rotate away from the impacted wisdom tooth (6) under the action of power, with the support base (2) as the fulcrum. During the rotation, the tool kit for extracting horizontally impacted wisdom teeth can conveniently and quickly extract the wisdom tooth through the lever principle, reducing clinical operation time and patient pain.
