Abstract

The invention relates to a spreader, in particular to a spreader for oral and maxillofacial surgery. According to the dilator for the oral and maxillofacial surgery, the upper jaw and the lower jaw of a patient can be supported, the oral cavity of the patient can be prevented from being hurt by sharp objects, and the distraction range can be conveniently adjusted. The dilator for the oral and maxillofacial surgery comprises a first cushion block, a second cushion block, a guide mechanism, an up-down distraction mechanism and the like, the first cushion block and the second cushion block are arranged up and down, and the guide mechanism used for guiding is arranged between the first cushion block and the second cushion block. And the guide mechanism is provided with an up-down opening mechanism for assisting the opening of the oral cavity of the patient. The upper jaw and the lower jaw of a patient can be supported through the first cushion block and the second cushion block, the oral cavity of the patient can be prevented from being hurt by sharp objects, the opening range of the oral cavity of the patient can be conveniently adjusted by rotating the screw rod, and a doctor does not need to hold the oral cavity for a long time.

Description

technical field [0001] The invention relates to a spreader, in particular to a spreader for oral and maxillofacial surgery. Background technique [0002] In human medicine, oral and maxillofacial refers to a part of human organs, because it contains a wide range, such as lips, ears, nose and eyes, so we call it the face most of the time. When doctors perform oral and maxillofacial surgery, most of the patients' mouths are opened, so as to facilitate the observation of the inside of the patient's oral cavity. Most of them use tools such as pliers or clips to open the patient's mouth, which requires the doctor to hold the tool with force for a long time, so it is easy to cause the doctor's hand muscle soreness, and it is not convenient to control the distance of the mouth opening, so It is also easy to cause secondary injury to the patient. [0003] According to the patent authorization publication number CN214761247U and the announcement date of 20211119, a spreader for ora...
