Example Embodiment

[0032] At present, there is an oral anesthesia pushing device (referred to as an anesthesia pushing device) on the market, which does not match the connection method of dental medical equipment. It can only meet the requirements through an independent operating system, such as connecting with a separate pedal control box. This brings great inconvenience to nurses or doctors in operation; meanwhile, the anesthesia device requires special consumables (disposable tubing), which increases the cost and diagnosis and treatment costs for doctors and patients; the anesthesia device generally uses a stepping motor For boosting anesthetics injection, 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 requires high electronic circuit design, which brings inconvenience to maintenance.

[0033] In view of this, the designers of the present invention have designed a screw dri...

Abstract

The invention provides a lead screw transmission mechanism and a booster for local anesthesia in the oral cavity, which belong to the field of medical devices and are used to be installed on the booster for local anesthesia in the oral cavity, including a screw main body, a drive nut, a motor, a guide, a first The Hall sensor assembly and the controller, wherein the output shaft of the motor is driven and connected to the main body of the screw, the drive nut is screwed on the main body of the lead screw, the drive nut is slidably connected to the guide, and the rotation of the drive screw drives the drive nut to reciprocate relative to the guide Movement; the signal of the first Hall sensor is connected to the controller for detecting the rotational speed of the motor, and the controller controls the connected motor. The screw drive mechanism is applied to a booster for local anesthesia in the oral cavity, which can accurately control the injection amount of medicine and improve the safety of medicine injection, and is convenient and quick to operate, sensitive to control, can be made into a pen type, and is easy to operate.

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...
