Oral cavity lesion tissue observation instrument

Abstract

The invention provides an oral cavity diseased tissue observation instrument, and relates to the field of medical tools. The oral cavity diseased tissue observation instrument comprises a device body, a skin biopsy device is arranged in the right end of the device body, and the left end of the skin biopsy device is clamped in the right end of a connecting sleeve. The electric motor drives the threaded column to rotate, so that the threaded plate can be driven to move along the threaded column, the skin biopsy device can stretch out and draw back in the probe under the driving of the connecting plate and the connecting sleeve, the sleeve is fixed to the left end of the connecting plate, the sleeve can stretch out and draw back and has a stretching range, and the threaded plate can be limited through the sleeve; the skin biopsy device can be driven to swing through the sleeve and the connecting block by rotating the pulley, so that the angle of the skin biopsy device can be adjusted, pathological tissues can be sampled through the skin biopsy device, and meanwhile, absorbent cotton can be arranged at a port of the skin biopsy device, so that the pathological parts can be accurately applied with medicine and stopped bleeding through the skin biopsy device.

Description

technical field [0001] The invention relates to the field of medical tools, in particular to an instrument for observing oral lesion tissues. Background technique [0002] The oral cavity is the beginning of the digestive tract. The anterior cleft communicates with the outside world, and the posterior pharynx connects with the pharynx. There are teeth, tongue and other organs in the oral cavity. The front wall of the oral cavity is the lips, the side wall is the cheek, the top is the palate, The floor of the oral cavity is composed of mucous membranes and muscles. The oral cavity is divided into the anterolateral oral vestibule and the posteromedial oral cavity by means of the upper and lower dental arches. The gap behind the third molars is connected. Clinically, when the patient's trismus is closed, a gag or cannula can be placed through this passage to inject drugs or nutrients while preventing tongue bite. [0003] In the process of using oral lesion tissue observation ...
