At present, with the improvement of life of people, more and more patients with tooth defects and missing can select a method of using an implant and matching a dental crown to recover the tooth chewing function of an oral cavity, but after the implant is implanted into the oral cavity, the dental crown falls off once the implant is used for a long time; the wound healing muscles grow to cover the implant completely, and the naked eye cannot distinguish where the implant is implanted on the jaw. The implant detector is a typical handheld medical product, and can help dentists automatically detect the accurate position of an implant, and determine the accurate position of an implanted metal object in a dental bed through the detector so as to accurately inlay teeth.

Detailed Description

Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings so that the advantages and features of the utility model may be more readily understood by those skilled in the art. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto.

The indicator lamp assembly 14 adopts a gradual display mode, and includes a center indicator lamp 141, a proximity indicator lamp 142, and a distance indicator lamp 143. The colors of the light approaching the indicator lamp 142, the center indicator lamp 141 and the far indicator lamp 142 are different, and the shape of the indicator lamp assembly 14 may be different. Specifically, in the present embodiment, the light colors and shapes of the proximity indicator lamp 142, the center indicator lamp 141, and the far indicator lamp 142 are different.

Referring to fig. 2, the proximity indicator lamp 142, the center indicator lamp 141, and the distance indicator lamp 143 are sequentially disposed along the length direction of the handle body 1 (i.e., the direction from the proximal end to the distal end). Specifically, when the sensor 31 reaches the very center of the implant, the center indicator light 141 displays blue, and the remaining lights are not lit; when the sensor 31 approaches the implant, the approach indicating lamp 142 displays green, and the remaining lamps are not lit; when the sensor 31 is far from the implant, the far indicator lamp 143 displays orange, and the remaining lamps are not lit. This makes it obvious to see whether the relation between probe 3 and the implant is in the state of approaching, in the state of being exactly central or far away when using and adjust according to the information that pilot lamp subassembly 14 suggests, and the location cycle is shorter, and it is very convenient to use, has improved work efficiency.

Referring to fig. 1 and 5, the oral implant detector further comprises a connecting frame 2 detachably connected with the handle body 1, and an obtuse angle is formed between the length direction of the handle body 1 and the length direction of the connecting frame 2, so that oral implant detection is facilitated. The oral implant detector has a first use state in which the sensor 31 faces upward to detect the upper jaw and a second use state; in the second use state, the sensor 31 faces downwards so as to be able to detect the lower jaw. Wherein, the handle body 1 and the connecting frame 2 are respectively provided with connecting parts, one of which is detachably inserted into the other; when the oral implant detector is in a first use state or a second use state, one connecting part is inserted into the other connecting part to connect the connecting frame 2 to the handle body 1; when the handle is switched between the first use state and the second use state, one connecting part can be pulled out from the other connecting part, and the connecting frame 2 and the handle main body 1 are separated from each other.

The slot 23 has a smooth inner surface, the plug 11 has a smooth outer surface, the inner surface of the slot 23 and the outer surface of the plug 11 are tightly attached, and the first housing 12 and the second housing 22 are kept connected into a whole by friction force therebetween. When the probing direction needs to be changed, the plug 11 can easily enter and exit the slot 23 because the inner surface of the slot 23 and the outer surface of the plug 11 are smooth. From another perspective, the oral implant detector is simple in structure on the premise that the detection direction is easy to replace.
