Abstract

The invention relates to the technical field of medical equipment, and in particular relates to a zygomatic chin expansion angle type opening device. The zygomatic chin expansion angle type opening device consists of a handle sheet, a handle, a rivet, a limiting band, a side fastening screw, a rear fastening screw, a post-tensioning splicing sheet, a rotating shaft, a shaft sleeve, a side sleeve, a positioning column, teeth, a rack, a front fixing strip, a pull ring handle, a pull ring, a spring, a pressing sheet, a pressing sheet shaft sleeve, a pressing sheet shaft, a pressing sheet shaft frame, a positioning pin, a positioning groove and position dividing bands, wherein the limiting band starts from the rear neck pit of the head of a patient, passes by the top of the head and is divided into left and right position dividing bands from the part between the eyebrows downwards, the two position dividing bands respectively pass through the lower edges of left and right cheekbones, the lower ends of the two position dividing bands are respectively positioned at temporal-mandibular joints on two sides of the head of the patient, and the lower edge of the middle part of the front fixing strip is positioned at the upper edge of mental protuberance. According to the zygomatic chin expansion angle type opening device, upper and lower jaws of the patient can be separated from each other without extending an instrument into the mouth of the patient.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a zygomatic and chin opening angle opening device. Background technique [0002] The mouth gag is an auxiliary device that opens the patient's mouth by external force, and is mainly used for opening the upper and lower jaws of the patient during oral surgery. However, the existing mouth gags all pry open the upper and lower jaws through instruments inserted into the oral cavity. On the one hand, such an operation will cause varying degrees of damage to the patient's teeth, gums and oral mucosa. Part of the space in the oral cavity will also block the field of view of the operation, reduce the operation space of the operation, and reduce the efficiency of the operation. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the present invention provides a zygomatic-chin opening angle opening device that can separate the upper and lower ...
