Technical Field

The utility model relates to the technical field of oral medical appliances, in particular to forceps.

Background

Along with the increasing demands of people on oral health, the oral cavity implantation technology is continuously developed, and the artificial tooth implantation is to implant a pure titanium artificial tooth root (implant) with high biocompatibility into an alveolar bone, and after the artificial tooth root and the alveolar bone are firmly combined for a plurality of months, the subsequent denture upper structure is installed.

When the upper structure is manufactured, an oral cavity model of a patient needs to be manufactured, and parts such as a base station, a dental crown and the like are selected based on the oral cavity model, so that preparation is made for subsequent denture installation. When the mould is planted and taken, the transfer rod is needed to be put into the implant bolt channel, the mould is taken by the silicon rubber, the transfer rod can be inserted into the silicon rubber impression, and the plaster filling mould is carried out after the substitute body is connected to the transfer rod. The purpose of the transfer rod is to determine the position and depth of the implant, so that the accuracy of the oral model is largely determined by the fit of the transfer rod with the implant in place.

In the actual operation process, after the transfer rod and the implant are placed in place, the transfer rod needs to be temporarily fixed, and then the central screw of the transfer rod is screwed so as to realize the correct in-place anastomosis of the transfer rod and the implant. The existing transfer rod positioning operation is mainly finished by bare hands of operators, specifically, after one hand is used for positioning the transfer rod, the other hand is used for screwing the central screw. Because the space in the oral cavity is narrow, especially when the missing tooth gap is small and the implant implantation is deeper, the operation visual field is limited, the transfer rod is difficult to be fixed by bare hands, the condition that the transfer rod is not screwed in place and is sprung and misplaced easily occurs, the transfer rod is repeatedly positioned slightly, the operation time is prolonged, and the pain is increased for patients; the model is distorted, the base station and the dental crown manufactured in a personalized way are invalid, and even parts accidentally drop and fall into the respiratory tract of a patient, so that unnecessary economic loss or disputes are caused.
