The invention relates to a portable mandibular protrusion locator, and belongs to the technical field of
medical instruments. The locator comprises a first clamping groove, a second clamping groove, a regulation device, a
stepper motor, a location controller and handheld
control equipment, wherein the regulation device comprises a grooved fixed block, a sliding block and a lead screw; the location controller comprises a location
Bluetooth module and a location control module; the handheld
control equipment comprises a handheld display input module, a handheld CPU (
central processing unit) control module and a handheld
Bluetooth module. The locator is not required to be worn when a patient sleeps during positioning, and can be independently removed after regulation, so that convenience and comfort are ensured; the mandibular protrusion distance accurate to a specific numerical value can be independently determined according to the
subjective feeling of the patient and
monitoring data, so that the most proper personalized protrusion position can be provided when an OSAHS (
obstructive sleep apnea-
hypopnea syndrome) patient receives treatment with mandibular protrusion snore-ceasing equipment, and a
treatment effect can be improved; the mandibular protrusion position of the OSAHS patient can also be predetermined, so that
blindness of clinical manufacturing of the mandibular protrusion snore-ceasing equipment is avoided, and the locator is easy to popularize and use.
