Description

Slot type intermaxillary traction assistor of upper and lower jaw dental arch

Technical Field

The invention relates to the technical field of maxillofacial surgery and orthodontics, in particular to a clamping groove type intermaxillary traction assistor for upper and lower dental arches.

Background

In the field of maxillofacial surgery and orthodontics, aiming at treatment of different degrees of malocclusal deformity caused by congenital or acquired diseases, small single teeth, local arch segments or implanted anchorage nails are used as anchorage nails to apply orthodontic force by rubber bands, and large whole maxillary or mandibular dentition is used as anchorage to apply larger force to elastically pull the jaw. Especially after orthognathic surgery for dentognathic face deformity and jawbone fracture surgery, the bone structure is easy to recur to the original malformed structure due to the force of soft tissue traction because muscles, ligaments and fascia and the like can not adapt to the change of the bone structure instantly. Therefore, the traction device is particularly important for the maxillary traction after the operations of verticality, class II, class III, oblique walking and the like of the upper and lower jaws. Through four to six weeks of reliable traction, stable near-far-middle-direction, left-right-direction and vertical-direction relations are kept between dentition or jawbone, a foundation is provided for postoperative reconstruction and balance of soft tissues such as a muscle system, and finally stable functional health, coordination and even beautiful appearance are obtained.

The elastic traction between the jaws usually needs to select a rubber ring with proper diameter and strength, starts from one or a group of traction hooks or anchorage nails (traction points) of the upper jaw or the lower jaw, is hung to a target position through single or double pass, straight line or broken line, box or triangle and the like according to different operation types and the direction of antagonistic muscles, and the resilience force formed after the rubber ring is stretched is the traction force needed to be utilized. On the third day after operation, a doctor can guide to complete the inter-jaw traction, and after the patient or the family member is taught, the rubber band is replaced by the patient or the family member three times per day within the period from discharge to six weeks after operation.

In summary, ensuring that the patient or family member can perform traction correctly and effectively is particularly important for the postoperative effect.

At present, a commonly used intermaxillary traction assistor is a medical vascular clamp (10cm or 12cm), although the operation is skillful by a doctor, patients and family members can not use the vascular clamp to carry out intermaxillary traction efficiently through practice feedback. The problems and reasons are summarized as follows:

1. the post-operation opening degree is small, and the visual field and the operation space are small;

2. the postoperative soft tissue still swells, the operation incision is not completely healed, and the operation difficulty is increased;

3. the traction sites are usually arranged in the cusp area and the molar area, the molar position is close to the surgical incision, the operation space is small, the visual field is poor, and the fear of patients or family members also increases the operation difficulty;

4. the medical vascular clamp is a right-handed instrument, and the closing and closing of the vascular clamp in the operation process have high requirements on an operator and higher operation difficulty;

5. the vascular clamp may accidentally injure the oral mucosa soft tissue;

6. the physiological radian of the alveolar bone is inconsistent with the curvature of the vascular forceps, so that different operation sites have different difficulties;

7. the inner side of the front end of the vascular clamp is serrated, and if the force is too large, the risk of accidental disconnection of the rubber ring can be increased;

8. the top end of the vessel forceps is round and blunt, and the rubber band is difficult to clamp by a single hand, so that the operation process is time-consuming and labor-consuming.
