Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an anesthesia mandibular bracket with an adjustment structure. Background Art

[0002] Clinical anesthesia uses anesthesia skills to anesthetize surgical patients, and controls, adjusts, monitors and treats the stability of vital signs to provide the best conditions for painlessness and safety. General anesthesia is one of the main methods of clinical anesthesia. When the patient falls asleep or is under general anesthesia, the patient's consciousness gradually disappears, the muscles in the mouth relax, and the tension of the soft tissue decreases, leading to relaxation of the mandibular joint and airway obstruction. If not treated in time, it will cause hypoxia and even endanger the patient's life.

[0003] Therefore, a chin support is used to support the patient's chin. When the chin is placed on the support, the patient's face is limited to fix the head. However, the size of the patient's head is different. The existing support cannot adjust the position of the face limiter, resulting in a gap between the face limiter and the head, causing the patient's head to shift, reducing the limiting effect on the head, and further reducing the support effect of the support. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art that the position of the face limiter cannot be adjusted, which reduces the limiting effect on the head and further reduces the supporting effect of the bracket, and to propose a mandibular bracket for anesthesia with an adjustment structure.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A mandibular support for anesthesia with an adjustment structure is designed, comprising an arc-shaped plate, a support mechanism connected to the arc-shaped plate, notches on both sides of the arc-shaped plate, each of the notches being rotatably connected to a limiting mechanism, each of the notches being connected to an adjustment mechanism for adjusting the position of the limiting mechanism, each of the adjustment mechanisms being connected to an elastic band, and one end of each elastic band being connected to the corresponding limiting mechanism;

[0010] Preferably, the limiting mechanism includes a baffle, one side of the baffle is rotatably connected to the notch, the baffle is fixedly connected to the elastic band, and a second elastic pad is fixedly connected to the baffle.

[0011] Preferably, fixing blocks are clamped on both sides of the baffle, a sterilization cloth layer is fixedly connected between the two fixing blocks, and the sterilization cloth layer is in contact with the second elastic pad.

[0012] Preferably, the sterilization cloth layer is a silver fiber sterilization cloth layer.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Example 1: Reference Figure 1-3 A mandibular support for anesthesia with an adjustment structure includes an arc-shaped plate 1, a support mechanism 2 is connected to the arc-shaped plate 1, slots 3 are provided on both sides of the arc-shaped plate 1, each slot 3 is rotatably connected to a limiting mechanism 4, each slot 3 is connected to an adjustment mechanism 5 for adjusting the position of the limiting mechanism 4, each adjustment mechanism 5 is connected to an elastic band 6, and one end of each elastic band 6 is connected to the corresponding limiting mechanism 4;

[0023] The adjustment mechanism 5 includes a mounting plate 51, which is fixedly connected to the slot 3. The upper end of the mounting plate 51 is fixedly connected to the elastic band 6. A second threaded hole is provided on the mounting plate 51, and a second threaded rod 52 is connected to the second threaded hole. One end of the second threaded rod 52 is fixedly connected to a sphere 53.

[0024] Working process:

[0025] When in use, the patient's lower jaw is placed on the bracket mechanism 2, which supports the lower jaw, and then the second threaded rod 52 is rotated. After the second threaded rod 52 rotates, it drives the ball 53 to move toward the limiting mechanism 4. After moving a distance, the ball 53 contacts the limiting mechanism 4 and pushes the limiting mechanism 4 to rotate. The limiting mechanism 4 rotates toward the patient's face. After the limiting mechanism 4 rotates, it pulls the elastic belt 6. The elastic belt 6 is stretched after being pulled and generates elastic force. After the two limiting mechanisms 4 rotate toward each other at a certain angle, they contact the patient's face to support and limit the patient's face. After anesthesia, the patient's head will not deviate, thereby improving the supporting effect of the bracket mechanism 2 on the lower jaw.

[0026] Example 2: In Example 1, when the lower jaw is supported by the bracket mechanism 2, the position between the bracket mechanism 2 and the limiting mechanism 4 is relatively fixed and cannot be adjusted, thereby failing to meet the need for adjustment. Figure 3 As another preferred embodiment of the present invention, the difference from Example 1 is that the bracket mechanism 2 includes two symmetrically arranged sliding grooves 21, the two symmetrically arranged sliding grooves 21 are opened on the arc plate 1, and a movable plate 22 is connected between the two symmetrically arranged sliding grooves 21, and a notch 23 is opened at the upper end of the movable plate 22, and a first elastic pad 24 is connected in the notch 23. A first threaded hole is opened on the movable plate 22, and a first threaded rod 25 is connected to the first threaded hole. One end of the first threaded rod 25 is rotatably connected to the sliding groove 21. When supporting the lower jaw, the lower jaw is located in the notch 23, and the first elastic pad 24 reduces the extrusion strength between the lower jaw and the notch 23. When the position of the movable plate 22 is adjusted, the first threaded rod 25 is rotated. After the first threaded rod 25 is rotated, the movable plate 22 moves in the vertical direction, thereby changing the distance between it and the limiting mechanism 4, and the position of the movable plate 22 can be adjusted.

[0027] Example 3: In Example 1, when the patient's face is supported and limited by the limiting mechanism 4, bacteria are easily adhered to the limiting mechanism 4, referring to Figure 2 As another preferred embodiment of the present invention, the difference from Example 1 is that the limiting mechanism 4 includes a baffle 41, one side of the baffle 41 is rotatably connected to the slot 3, the baffle 41 is fixedly connected to the elastic band 6, and a second elastic pad 42 is fixedly connected to the baffle 41. Fixed blocks 43 are clamped on both sides of the baffle 41, and a sterilization cloth layer 44 is fixedly connected between the two fixed blocks 43. The sterilization cloth layer 44 is in contact with the second elastic pad 42. The sterilization cloth layer 44 is a silver fiber sterilization cloth layer. When the patient's face is supported and limited, the baffle 41 contacts the patient's face through the second elastic pad 42 and the sterilization cloth layer 44, supporting and limiting the patient's face. The sterilization cloth layer 44 has a sterilization effect, thereby reducing the bacteria on the second elastic pad 42 and the baffle 41.

[0028] Example 4: In Example 1, the height of the arc plate 1 cannot be adjusted when supporting the mandible. Figure 4 The cam 72 is fixed on the upper end of the support frame 71 and the support frame 72 is fixed on the support frame 71. The cam 72 is fixed on the upper end of the support frame 71 and the support frame 72 is fixed on the support frame 71.

[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
