Description

Technical Field

[0001] The utility model relates to the technical field of oral examination equipment, in particular to a portable examination device for stomatology. Background Art

[0002] When a stomatologist performs root canal treatment on a patient, it is necessary to first drill a hole at the top of the tooth, and then rely on an oral endoscope and a mouth mirror to take pictures at the drilled hole to check the root canal morphology and position of the tooth. However, they cannot extend into the inner part of the tooth pulp cavity, so the exact position of the root canal cannot be found. Moreover, the root canal positions of the teeth of each patient are different, and the tooth pulp cavities of older patients are even closed. The root canal position cannot be known through CT and oral endoscope photos. Doctors can only rely on experience and spend more time looking for the root canal position. The treatment time is relatively long, and the existing oral optical mirror equipment is large in size and relatively expensive, so the treatment cost of patients is very high and it cannot be popularized to the stomatology departments of each hospital. In addition, oral examinations also require auxiliary instruments such as forceps and probes. When going out for medical treatment, it is not convenient to carry them with you, and these instruments that come into contact with the oral cavity need to be disinfected before use. The existing kits cannot meet such requirements conveniently and efficiently, and a new type of device is needed to solve this problem. Content of the Utility Model

[0003] To solve the above problems, the utility model provides a portable examination device for stomatology, which includes a probe handle. An integrated wire is arranged inside the probe handle. One end of the integrated wire is connected to a terminal block A at the end of a bent screw tube of the probe handle. The end of the bent screw tube is threadedly connected to a disc seat of a probe head. After a terminal block B in the disc seat is butted against the terminal block A, the integrated wire is connected to a light guide beam and a transmission cable inside the probe needle tube. The transmission cable is connected to the output end of an image sensor, and the input end of the image sensor is located behind an optical mirror at the orifice of the needle tube. The other end of the integrated wire is connected to the end of an external cable through an external connection block. The end of the external cable is threadedly connected to the bottom of the probe handle, and the other end of the external cable is connected to an external light source and a display.

[0004] Furthermore, the device further includes a cylinder body. Column grooves are opened on both sides of the cylinder body, and the probe handle and the needle handle are respectively placed in the two column grooves. Through grooves and narrow grooves are respectively opened on the remaining two sides of the cylinder body. An alcohol bottle is inserted into the through groove, and forceps are clamped in the narrow groove. A cylinder cover is threadedly connected to the top of the cylinder body, and a removed probe head, a mouth mirror and a probe are arranged inside the cylinder cover.

[0005] Furthermore, a connection seat is arranged at the center of the bottom surface of the mouth mirror, and the connection seat can be threadedly connected to the bent screw tube. A lamp ring is arranged on the edge of the mouth mirror, and the lamp ring is connected to a battery inside the mouth mirror.
