Embodiment 1

[0021] see Figure 1-3 , the present invention provides a technical solution: a jaw bracket for complete intravenous anesthesia without intubation. Two positioning bolts 2 are respectively screwed to the front and rear ends of the upper surface of the two channel steel plates 1, and the reinforcing ribs 3 are fixedly connected to the inner rear end of the channel steel plates 1 to improve the stability between the two channel steel plates 1, and also include a support plate 4. The first rotating shaft 5, the supporting mechanism 6, the angle adjusting mechanism 7 and the positioning mechanism 8, the supporting plate 4 is fixedly connected to the middle part of the upper surface of the channel steel plate 1 located on the left side, and the first rotating shaft 5 is rotatably installed on the support through a bearing On the right side of the plate 4, the support mechanism 6 is fixedly connected to the right end of the first rotating shaft 5, and the angle adjustment mechanism ...

Embodiment 2

[0031] The difference with embodiment 1 is:

[0032] see Figure 4 , the present invention provides a technical solution: the mandibular support mechanism 9 includes a limit sleeve 91, a limit plate 92, a sliding rod 93, a mandibular body support 94, a sliding sleeve 95, a stop bolt 96 and a mandibular angle support 97, the limit The number of sleeves 91 is two, which are respectively fixedly connected to the top front sides of the two channel steel plates 1, the limiting plate 92 is plugged into the inner cavity of the limiting sleeve 91, and one end of the sliding rod 93 is fixedly connected to the inner top of the limiting plate 92 , the outer wall of the sliding rod 93 is rectangular, the sliding rod 93 limits the rotation of the sliding sleeve 95 to ensure that the mandibular corner support 97 can move horizontally, the mandibular body support 94 is fixedly connected to the other end of the sliding rod 93, and the sliding sleeve 95 can slide left and right. On the outer ...

Abstract

The lower jaw bracket comprises two channel steel plates, four positioning bolts and a reinforcing rib, the two channel steel plates are oppositely arranged, the four positioning bolts are connected to the front ends and the rear ends of the upper surfaces of the two channel steel plates in a screwed mode respectively, the reinforcing rib is fixedly connected to the rear ends of the inner sides of the channel steel plates, and the reinforcing rib is fixedly connected to the inner sides of the channel steel plates. The supporting plate is fixedly connected to the middle of the upper surface of the channel steel plate located on the left side; the first rotating shaft is rotatably mounted on the right side of the supporting plate through a bearing; the supporting mechanism is fixedly connected to the right end of the first rotating shaft; the angle adjusting mechanism is installed in the middle of the upper surface of the channel steel plate located on the right side. The lower jaw of a patient can be lifted for a long time, and the head of the patient can be kept in a backward leaning state, so that the purpose of keeping the upper respiratory tract of the patient unobstructed during intravenous anesthesia without intubation in a short operation is achieved, the anesthesia safety of the patient is facilitated, and physical exhaustion and anesthesia working intensity of an anesthetist can be relieved.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a jaw bracket for total intravenous anesthesia without intubation. Background technique [0002] During general anesthesia, endotracheal intubation is the strongest stimulus. Endotracheal intubation under light anesthesia can cause severe coughing, suffocation and even bronchospasm. Arrhythmia, ventricular fibrillation, etc., can be life-threatening in severe cases. At the same time, some patients are not suitable for general anesthesia using muscle relaxant drugs and endotracheal intubation, especially the following groups: ① patients with myasthenia gravis undergoing thymectomy; ② severe chronic obstructive pulmonary disease (chronic obstructive pulmonary disease, COPD) undergoing thymectomy Lung volume reduction surgery; ③allergic to muscle relaxants; ④pregnant women who need general anesthesia; ⑤tracheal tumor resection, carina reconstruction; ⑥casters, singers and other sp...
