Description

A kind of auxiliary anesthesia device for dental surgery

technical field

The invention relates to the technical field, in particular to an auxiliary anesthesia device for dental surgery.

Background technique

Dentistry, one of the categories of medical disciplines, mainly treats diseases related to teeth and periodontal. During dental surgery, especially for operations such as tooth extraction and drilling that need to be processed on teeth, it is necessary to perform gingival surgery on the affected area in advance. A local anesthetic is injected at the site to reduce pain during the procedure.

At present, the injection of anesthesia into the gums mainly relies on a syringe. The specific operation is to use a syringe filled with anesthesia to puncture the gums to perform local anesthesia. Although effective local anesthesia can be performed, especially When performing dental surgery on children, because the syringe will be relatively painful when puncturing the gums, and the children themselves have poor self-control, and the response to pain is more sensitive and severe, so in the process of puncturing the gums with the syringe, the children are affected by pain. It is very easy to shake the head uncontrollably, and the syringe is also a relatively large part relative to the oral cavity, and the operator holds the hand, so that when the head is shaken, the needle of the syringe is very easy to move relative to the gums, and the needle It is also extremely thin and sharp, which can easily lead to secondary damage to the position of the gums, which not only affects the stability of the dental operation, but also easily increases the psychological fear of children, causing them to easily contradict dental operations.
