Description

Electric screwdriver for dental implantation and dental restoration

Technical Field

The utility model relates to an electric screwdriver, in particular to an electric screwdriver for dental implant and dental restoration.

Background

In the treatment process of dental implantation and dental component restoration, a doctor needs to tighten or loosen screws and accurately apply force to the implanted and restored dental component by means of a screwdriver and a torque wrench. Currently, there are two main types of tools used in clinical settings: one is that the force can be applied only by one-way moving with the help of a torque wrench; the other type can be used for bidirectional manual rotation force application. Both tools need to be held by both hands when in use, the screw tightening efficiency is low, the labor intensity is high, and the risk of aspiration or swallowing by mistake caused by dropping the apparatus into the mouth of a patient is easy to occur.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an electric screwdriver that restoration tooth was used is planted in oral cavity, solve the needs both hands that exist when the used instrument of current planting restoration tooth part used and control, elasticity screw inefficiency, the big problem of intensity of labour.

The purpose of the utility model is realized like this: the electric screwdriver includes: the screwdriver head comprises a machine head, a connecting sleeve, a motor, a handle, a battery, a shell and a screwdriver head; the front end of the shell is connected with a machine head, the rear end of the shell is connected with a handle, a battery is connected in the handle, a connecting sleeve and a motor are connected in the shell, the connecting sleeve is connected on an output shaft of the motor, the battery is connected with the motor through a switch, and the battery supplies power for the motor; the machine head is connected with a screwdriver head.

The handpiece includes: the rotary drum comprises a rotary drum connecting rod, a universal joint, a rack bar and a bevel gear; one end of a rotary drum connecting rod is connected with the connecting sleeve, the other end of the rotary drum connecting rod is connected with one end of a universal joint, the other end of the universal joint is provided with a basin gear, one end of a toothed bar is provided with teeth meshed with the basin gear, one end of the toothed bar is provided with a bevel gear, the bevel gear is a bevel gear pair, and the other bevel gear which is meshed with the bevel gear is connected with a screwdriver head.

The invention has the beneficial effects that by adopting the scheme, the screw of the dental implant component is subjected to elastic stress application by accurately controlling the rotating speed, the steering and the stress application torque of the motor and the correcting head held by the working section, and the invention has the following positive effects:

1. the working efficiency of the motor drive relative to the manual rotation is greatly improved.

2. The device has the function of stopping the overload of the stress application to prevent the damage of the planting part.

3. The connecting sleeve can be disassembled and sterilized at high temperature, so that the clinical replacement and hospital feeling control are facilitated.

4. The single-hand operation is convenient and fast, and the labor intensity of doctors is greatly reduced.

5. The screwdriver head is held firmly to prevent the instrument from falling into the mouth of the patient and causing danger.

The problem of the used instrument of the present used instrument of planting restoration tooth part exist when using need both hands to control, elasticity screw inefficiency, intensity of labour is big is solved, the utility model aims at.

The advantages are that:

1. the rotating speed, the steering and the stress application torque of the motor driven and accurately controlled motor are greatly improved relative to the working efficiency of manual rotation.

2. Convenient and fast one-hand operation, and is beneficial to safer and more accurate treatment operation in narrow intraoral space.

3. The screwdriver head is held firmly to prevent the instrument from falling into the mouth of the patient and causing danger.
