Abstract

The invention relates to medical equipment for dental operation, and in particular relates to a medical oral cavity positioning spreader. The spreader comprises a mandibular support sleeving mandibular teeth, a maxillary support sleeving maxillary teeth and a plurality of connecting rods hinged between the two supports, wherein the connecting rods are connected to a center shaft through hinged shafts; and a turbine worm mechanism for driving the hinged shafts to move is arranged on a position, between the two hinged shafts, of the center shaft. The spreader is compact in structure, convenient to use, accurate in positioning, safe and reliable and has the advantages that the oral cavity of a patient can be positioned at any angle through the self-locking function of the turbine worm mechanism, no extra locking mechanism is needed, the danger and the hidden danger caused by suddenly closing of the oral cavity of the patient are avoided.

Description

technical field [0001] The invention relates to a medical device for dental surgery, in particular to a medical oral cavity positioning spreader. Background technique [0002] In oral surgery and inspection, in order to facilitate operation, the patient's mouth needs to be opened to a certain extent and kept for a certain period of time. However, some patients lose consciousness due to anesthesia and other reasons, and cannot open their mouths actively, so various surgical instruments need to be used to prop up the patient's oral cavity. Chinese patent 2010101762485 discloses an "Integral Active Mouth Mouth", and another Chinese patent 2010101758935 discloses a "Split Active Mouth Mouth", both of which are provided with a torsion spring between the upper jaw plate and the lower jaw plate, The torsional force of the torsion spring is used to keep the maxillary plate and the mandibular plate with a certain outward expansion force. During use, the doctor or the patient pinche...
