RU89948U1 - DEVICE FOR FASTENING FRAGRANCES AT Fracture of the upper jaw - Google Patents

Abstract

A device for fixing fragments in a fracture of the upper jaw, characterized in that it contains a tooth arch, the first extraoral part at an angle to the tooth arch in the area of the medial incisor, a bend in the form of a dental arch from the level of the second molar to the corner of the mouth, the second extraoral part at an angle to the bend , the third extraoral part at an angle to the second part and two extraoral levers ending in a hook to secure the rubber rings.

Description

The utility model relates to medical equipment, namely to a group of devices for fixing fragments in case of fracture of the upper jaw.

Among medical instruments, there are various devices used to fix fragments of the upper jaw after their reposition [Injuries of the maxillofacial region / Ed. N.M. Aleksandrova, P.Z. Arzhantseva. - M .: Medicine, 1986. - S.184-186]. However, they are complex in design, bulky, create inconvenience to the patient during sleep and are not always applicable for combined craniocerebral trauma.

A device for fixing fragments of the upper jaw "deer horns" [Galmoshch Yu. Traumatology of the maxillofacial skeleton. - Bratislava, 1975. - S.172-174].

However, this device is also complex in design. To be individual, requires laboratory manufacturing. If it is standard, then its intraoral part may not correspond to the shape and size of the dental arch of a particular patient, which will reduce the rigidity of securing fragments and reduce the effectiveness of treatment.

The goal achieved using the utility model is to simplify the design while maintaining individualization and rigidly securing fragments of the upper jaw.

This goal is achieved by the fact that the device for fixing fragments of the upper jaw contains a tooth arch, three horizontal extraoral parts with two vertical extraoral elastic arms, which end with a hook to secure the rubber rings.

Figure 1 shows a device for fixing fragments of the upper jaw general view; figure 2 is the same in working condition.

A device for securing fragments in a fracture of the upper jaw is made of a standard Kirshner needle of medium diameter and consists of a tooth (intraoral) part 1, three horizontal extraoral parts 2 and 5, and two vertical extraoral elastic arms 3 ending in hook 4 for applying rigid (elastic) stretching .

The device is manufactured as follows. The tooth part 1 is bent in the form of a dental arch of the upper jaw from the medial incisor to the second molar of one side, horizontal bend 2 is made in the region of the medial incisor at an angle of 90 ° to the tooth part, after which the extraoral vertical arm 3 is bent, which ends with hook 4, then onto at the level of the second molar, the needle is bent 180 ° and the existing bend is repeated in the form of a dental arch to the angle of the mouth, at this level a second horizontal bend 2 is made at an angle of 90 ° to the tooth part 1, then the needle is again bent at an angle of 90 ° and, in the direction and the second molar, form the third horizontal part 5, then at the level of the second molar an extraoral vertical lever 3 is bent, which ends with a hook 4. The horizontal parts 2 and 5 are bent so as not to injure the upper lip and the corner of the mouth.

The device operates as follows.

The tooth part 1 of the device is fixed with a ligature wire to the teeth of the upper jaw. An Entin hat or a plaster hat with hooks corresponding to the device hooks is fixed on the patient’s head. After reposition of the fragments, the hooks 4 of the device and the hooks of the caps are fixed between each other by rigid or elastic traction.

Changing the angle of inclination of the levers 3 allows you to achieve not only a rigid fixation, but also, if necessary, skeletal traction of the fragment. For each patient, the device is manufactured individually, which allows to achieve optimal conditions for treatment. The device can be used both for temporary (transport) and for permanent (medical) fixing of fragments. With a unilateral fracture, one device is used, with a bilateral fracture, two devices are used.
