Embodiment Construction

[0032] At present, there is an oral hemp massager (referred to as a hemp massager) on the market, which does not match the connection method of oral medical equipment. It can only meet the requirements through an independent operating system, such as connecting with a separate foot control box. , which brings great inconvenience to nurses or doctors in operation; at the same time, the hemp pushing device requires special consumables (disposable pipelines), which increases the cost and diagnosis and treatment expenses for doctors and patients; the hemp pushing device generally uses stepping motors Boosting anesthesia injection, but the lack of overload protection for the stepping motor directly leads to physical damage to the stepping motor; at the same time, the control system is too complicated, and the requirements for electronic circuit design are high, which brings inconvenience to maintenance.

[0033] In view of this, the designer of the present invention designed a screw...

Abstract

The invention provides a lead screw transmission mechanism and an oral local anesthesia booster, and belongs to the field of medical instruments. The lead screw transmission mechanism used for being installed on the oral local anesthesia booster comprises a lead screw main body, a transmission nut, a motor, a guide member, a first Hall sensor assembly and a controller, wherein an output shaft of the motor is in drive connection with the lead screw main body; the transmission nut is in screwed connection with the lead screw main body; the transmission nut is slidably connected to the guide member; a transmission lead screw rotates to drive the transmission nut to do reciprocating motion relative to the guide member; the first Hall sensor assembly is in signal connection with the controller, and is used for detecting the rotating speed of the motor; the controller is in control connection with the motor. The lead screw transmission mechanism applied to the oral local anesthesia booster can accurately control the injection amount of drugs and improve the injection safety of the drugs, is convenient and rapid to operate, and sensitive to control, and can be made to be of a pen type for convenience of operation.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a screw drive mechanism and a booster for oral local anesthesia. Background technique [0002] Oral disease is a common disease among people, and oral local anesthesia is a commonly used method in oral surgery. At present, the department of stomatology has been following the traditional local anesthesia method of manual injection for the preparation of the abutment teeth of the vital pulp. Due to the strong puncture pain and injection pain, patients often have injection fear, nervousness and anxiety, and are unwilling to see a doctor. , and even give up the psychology of treatment. Especially for patients with systemic diseases such as hypertension and coronary heart disease, the pain and tension during injection can lead to serious complications. [0003] At present, there is an oral hemp massager (referred to as a hemp massager) on the market, which does not match the connectio...
