Description

Multifunctional tweezers

Technical Field

The utility model relates to the technical field of dental implants, in particular to a pair of multifunctional tweezers.

Background technique

Dental implants are known as the third set of teeth for humans after deciduous teeth and permanent teeth. They are a boon to patients with missing teeth. Their structure and function have been continuously improved and optimized in clinical practice. The general restoration process of dental implants is to first bury the implant in the alveolar bone, wait for 2-6 months, and wait for the implant to form a bony connection with the alveolar bone. Then, take a tooth model from the patient, make a crown, put the abutment on the implant, use a screwdriver to rotate the central screw to fix it on the implant, and then fix the crown on the abutment. The implant restoration is complete.

During the operation of dental implants, the implant, abutment, crown and other components generally need to be placed in the mouth by the doctor using tweezers or the fingers of the left hand, and then the doctor uses the right hand to hold the tool to install the components. At least three fingers need to be placed when placing by hand, and the doctor's vision will be blocked by his own hands, so he can only operate blindly, which can easily cause medical accidents such as the restoration components slipping and being swallowed or inhaled by the patient. Although placing the implant in the mouth by clamping with tweezers can avoid obstruction of the operating vision, there is still a risk that the clamped component will collapse into the mouth from the front end of the tweezers. In addition, after the doctor uses the tweezers in his left hand to place the clamped component in the corresponding position of the alveolar socket, he needs to use the right hand to hold the instrument to install the clamped component. At this time, the patient's mouth needs to be opened at a larger angle. However, it is often difficult for the patient to actively open the appropriate angle, and an assistant is needed to help pry the patient's mouth open at an appropriate angle, which not only wastes manpower, but also occupies space in the mouth, affects the operating field of view, and improper operation may also cause injury to the patient.
