Description

Dental mirror structure with replaceable lens

This creation relates to an oral lens structure with interchangeable lenses, especially an oral lens structure that facilitates the assembly and disassembly of lenses. The lens is fitted into the observation portion at one end of the grip. The observation portion is provided with a perforation. By pushing the lens away from the observation part, the effect of replacing the lens can be achieved, which effectively reduces the cost and is environmentally friendly, and it has the effect of easy assembly and convenience.

The dentist clinically uses an oral mirror to open the tongue or cheek to expose the teeth to observe each tooth surface. The oral mirror includes a handle and an observation end, and the observation end is provided with a concave portion for a lens to be set. Mirror extended into the cavity for observation and treatment.

The lenses of common dental mirrors can be broadly classified into two types: fitted or fitted.

According to the conventional knowledge, the fixed structure of the fixed dental mirror lens, such as the "improved structure of disposable dentist mouth mirror" disclosed in the domestic new patent No. 082206163, is mainly made by integrally forming the handle and the frame, in which the mirror The frame is provided with a concave edge for pivotal connection of the lens. The handle is pivotally placed on the side edge of the frame and extends to an appropriate angle to the outer edge. The handle is provided with a tapered rod body It is characterized by the position of the pivotal edge of the handle's tapered rod body adjacent to the frame, and a supporting edge portion extending downward from the lower edge of the thinnest rod portion of the handle body, the supporting edge portion Extend a reinforcing beam to the bottom edge of the frame.

Another conventional fixed-type oral lens lens fixing structure, such as the "improved structure of disposable medical mouthpieces" disclosed in the domestic new patent No. 087203031, its structural features are: in the search handle groove of the mouthpiece, A reflective patch is attached to form a reflective device; in addition, a stirring knife handle is integrally formed on the end of the mouth mirror body to facilitate the dentist to stir the medicine or tooth filler users.

In the above disclosed structure, in the former, the handle and the frame are integrally formed, and the frame is formed with a concave edge, and the lens can be fitted into the concave edge, and the handle is provided as a tapered rod body The side edge of the frame, and the lowermost edge of the thinnest rod part of the handle rod body has a supporting edge part extending downward, and the supporting edge part extends a reinforcing beam to the bottom edge surface of the frame; the latter is composed of a search handle and a caliber grip The mixing knife handle is formed in one piece, the search handle is round and has a groove body, and the reflective patch is placed in the groove.

However, the above-mentioned conventional lens fixing methods cannot be replaced regardless of whether they are fitted or fitted. Nowadays, most of the lenses are reflective patches, which are easy to scratch when used, that is, they need to be discarded, which increases the cost and makes them invisible. It causes waste and is not environmentally friendly, and the overall structure really needs to be improved.

In view of this, the present invention discloses an interchangeable lens oral mirror structure, which includes: a grip rod; an observation part, which is provided at one end of the grip rod, and the observation part is provided with a groove, which is provided in the observation part The location is provided with a perforation communicating with the groove; a lens, so that the lens is embedded in the groove; with the above-mentioned components, a tool can be inserted into the perforation of the observation part and the lens can be removed from the groove to replace the lens The effect, without having to abandon the entire set of oral mirrors, effectively reduce costs and environmental protection, its assembly is easy and convenient, and indeed has excellent innovation and convenience and practicality.

The oral lens structure of the replaceable lens of the present invention is provided with a perforation in the groove of the observation portion at one end of the grip rod, which is to fit and position the lens in the groove, which can be used when the lens needs to be replaced The top pillar with a column is inserted into the perforation, and the lens is lifted upward to catch the lens out of the groove, so that the effect of replacing the lens can be achieved without having to discard the entire set of oral mirrors, which effectively reduces costs and is environmentally friendly. Its assembly is easy and convenient. Those with excellent practicability and convenience; furthermore, the cover perforated at the groove perforation in the groove of the observation part is provided with a cover to provide waterproof and dustproof effects; it can further be provided with a tool holder The top surface is respectively provided with a first accommodating groove and a second accommodating groove. The preset position inside the first accommodating groove is provided with a vertical post vertically, which can embed the observation part in the first accommodating groove, so that the top post is aligned with the perforation , When the observation part is inserted downward into the first receiving slot, the top post is inserted into the perforation and the lens is lifted upwards to catch the lens out of the groove, and the effect of lens replacement can be achieved; it can set a lens in the second receiving slot Inside, and then reverse the observation part so that the groove is set downward and embedded downward into the second receiving groove, the lens can be fitted and positioned in the groove to achieve the convenience of assembling the lens; the observation A first abutment edge is formed on the top edge of the groove to extend inwardly. When the lens is fitted into the groove, the first abutment edge abuts the top edge of the lens to provide a stable position; it can Further, it is provided that the side edge of the lens forms a tapered upwardly inclined edge surface, and the observation portion extends toward the inner side of the groove to form a second resisting edge, so that when the lens is fitted into the groove, the second resisting The stop edge resists the side edge of the lens to achieve the effect of stabilizing the fixed position; it can also be set such that the inner side wall surface of the observation portion corresponds to the side edge of the lens and extends toward the groove to form a side wall that slopes downward and gradually expands, so that When the lens is fitted in the groove, the side edge and the side wall are mutually fixed against each other, which can also achieve the effect of stabilizing the fixed position.
