A hand tool for dentistry and/or dental prosthetics, having a grip part which defines a main axis and, in the direction of the main axis, comprises a front end area and a rear end area. The grip part has, in the front end area, an open receiving recess in which the collet element is arranged with an adjustable receiving diameter for receiving an object. The receiving diameter of the collet element can be modified by way of an actuating device. The collet element can be secured against rotation in the grip part.

A system of tools for use in an orthodontic setting made up of a series of individual tools. Each tool comprises a pair of flat, generally elongated arms placed in an adjacent lengthwise relationship and connected at each first ends in a manner so as to force the remaining portions of the arms apart. Each of the tools has specially modified features that allow the tools to perform specific functions such as: scraping teeth and orthodontic devices; grasping orthodontic brackets; placing orthodontic brackets onto a tooth without disturbing other free-floating brackets; measuring the distance between portions of a tooth so as to ensure proper bracket placement; measuring the distance between orthodontic brackets; and aseptically retrieving objects from a drawer.

The present invention relates to a pliers that includes first and second arms that are pivotally interconnected utilizing an appropriate mechanical fastener. A spring is generally disposed about the mechanical fastener to bias the pliers toward an open condition. Further, a bearing is generally located between the first and second arms to hinder friction between the first and second arms, facilitate movement of the pliers between open and closed conditions, and provide some control for the range of pivotal motion of the first arm relative to the second arm.

A dental instrument includes a first arm, a second arm, which is pivotally coupled to the first arm about a pivot axis, and a spring. The first and second arms are pivotal with respect to each other in a plane generally orthogonal to the pivot axis. Each of the arms has a proximal portion, a medial portion, and a distal portion, with the proximal portions defining hand grip portions, and with the arms being pivotally connected at their medial portions. The spring biases the distal portions of the arms toward each other. Each of the distal portions comprises a first portion and a prong portion depending from the first portion. The prong portions comprise back-to-back generally C-shaped portions and spaced apart tines. The C-shaped portions define a pair of seats, with the tines depending from the seats and having spaced apart distal ends adapted for engaging a rubber-dam clamp, and the seats providing contacts for a dental retaining ring.

Dental forceps for holding dental articulating paper has dual elongated spring arms, moveable toward and away from each other. The spring arms each have a lower handle section, an intermediate section extending from the lower handle section, and an upper section with a cantilevered member extending from the top end of the intermediate section. Clamping support arms extend outward from and perpendicular to the cantilevered member of each of the spring arms. The support arms have jagged surfaces which enhance the paper holding capability of the spring arms. When the spring arms are fully biased away from each other, the support arms are closed and articulating paper is held therebetween. When the lower handle sections of the spring arms are moved together, the support arms open to release the paper.

The invention discloses a heavy disposable dental forceps, which includes a plastic body with a metal entity. The main body includes a set of tweezers, forceps arm, each of the forceps arms are provided with a cavity portion. In fact, the entity body of the metal pattern to extend into the body cavity in a solid portion provided in a recess on the body by the forceps. Heavy metal entity set disposable dental forceps have a certain weight in order to facilitate the use of medical personnel to operate. The use of such dental forceps, tweezers body medical staff can no longer be discarded after use reusable metal entity were retained for the next inserted on the new tweezers body again. The forceps may have a better use of the body indicator for indicating use state of the main body of the forceps. By interpreting the use of indicator, the user can know whether the body has been used forceps before.

The present invention provides a tweezer for dental and other applications. The tweezer including a main body portion (12, 14) extending in a generally longitudinal direction. The main body portion having a first end (20) and a second end (18). A hinge connector (16) is located between the first end and the second end. A first pair of pincers is located at the first end (20). A second pair of pincers is located at the second end (18). A bias mechanism (22) urges the first pair of pincers (20) into a closed position and urging the second pair of pincers (18) in an open position, whereby the user may apply a force to the tweezers to overcome the bias mechanism (22) and urge the first pair of pincers (20) away from the closed position and the second pair of pincers (18) away from the open position.

The invention discloses an ophthalmic comprehensive examination diagnostic unit which comprises a base plate and a diagnostic plate. The surface of the base plate is connected with the diagnostic plate through a stand column, a through groove is formed in the center of the surface of the diagnostic plate, a lead screw is arranged in the through groove in a penetrating mode, the two ends of the lead screw are connected with the diagnostic plate through bearings, one end of the lead screw penetrates through the diagnostic plate, a hand wheel is connected to the end of the lead screw, a movable block is connected to the side face of the lead screw through a thread pair, a sliding plate is connected to the top of the movable block, guide rails are arranged on the two sides of the surface of the diagnostic plate respectively, first sliding grooves formed in the bottoms of the two ends of the sliding plate and the guide rails are installed in a matched mode, and an installation plate is arranged at the top end in the middle of the sliding plate. According to the ophthalmic comprehensive examination diagnostic unit, dichroscope and a microscope can be adjusted simultaneously and synchronously when a lens is adjusted, the precision of the adjusted position is still high, the examination effect is not affected, synchronous adjustment can be achieved, the consumed time of adjustment is short, and the examination efficiency is high.

A cannula for evacuating irrigation fluid, saliva and/or blood for use in the dental field is formed of three interconnected tubular conduits and includes two hollow tube members one of which includes a first aperture formed on a buttressed plate parallel to the first tubular member, a second aperture being located on an upper part of the distal portion of the second tubular member allowing simplified placement and removal by engaging forceps in the apertures and use of the cannula with a first branch of the cannula inserted between the teeth and the tongue of a patient and the second branch of the cannula inserted between the teeth and the cheek of the patient.

The invention discloses a high-stability dentist's nipper and relates to the technical field of dentist's utensils. Nipper heads are mounted at the front end of a nipper body, an antiskid pad is mounted on the inner side of each nipper head, a handle sleeve is connected at the rear end of the nipper body in a sleeved manner, a connecting block is arranged on the inner side of the nipper body, a roller is mounted at each of two ends of the connecting block, the rollers are mounted in sliding grooves of the nipper body, a connecting rod is connected with one end of the connecting block and connected with a driving rod of a driver, and a driving pad is mounted inside the nipper body. The high-stability dentist's nipper is convenient for realizing quick clamping, less prone to sliding, simple to operate, convenient to use, time saving and high in working efficiency.

The pliers, preferably in the form of dental pliers, include first and second members. Each of the members includes a handle portion and a jaw portion. The members are pivotally connected for movement of the jaw portions between remote and proximate positions. One of the jaw portions has a recess within which a nichrome heating element is situated. First and second wires extend into the recess and are connected to the heating element. The wires are connected to a variable power source to electrically energize the heating element such that the jaw portion of the pliers with the heating element is heated to the desired degree.
