Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tooth extraction assisting devices, and particularly relates to a minimally invasive tooth extraction assisting device for oral and maxillofacial surgery. BACKGROUND

[0002] Minimally invasive tooth extraction in oral and maxillofacial surgery is a tooth extraction surgery performed using minimally invasive techniques, aiming to reduce surgical trauma, shorten postoperative recovery time and reduce the risk of postoperative complications. This minimally invasive surgical method has many advantages over traditional tooth extraction surgery. The following are the general steps of minimally invasive tooth extraction in oral and maxillofacial surgery:

[0003] Anesthesia: Before the tooth extraction surgery, the oral and maxillofacial surgeon will perform local anesthesia or general anesthesia on the patient to ensure that the patient has no pain during the surgery.

[0004] High-precision diagnosis: The oral and maxillofacial surgeon may use X-rays, CT scans or other imaging techniques to accurately assess the position of the tooth, the condition of the surrounding bone and the potential difficulty of the surgery.

[0005] Surgical preparation: Before the tooth extraction surgery, the doctor will disinfect and anesthetize the local hemostasis of the surgical area.

[0006] Incision and tissue separation: The oral and maxillofacial surgeon will make a small incision around the tooth to be extracted, and then gently separate the soft tissue to obtain a good surgical field of view.

[0007] Tooth loosening and extraction: The doctor will use special dental instruments such as torque or tooth extraction forceps to gently loosen the tooth and gradually extract it.

[0008] Wound suture: As needed, the oral and maxillofacial surgeon may suture the wound after the surgery to promote healing.

[0009] In the above steps, the stability of the doctor's arm is extremely important during the work of anesthesia, incision and tissue separation, tooth loosening and extraction, and wound suture. Some inexperienced doctors will shake during the process of long-term suspension of the right arm, and the uncontrolled arm is extremely easy to cause additional harm to the patient.
