[0002] A mouth fixator is an instrument used to fix the position of the mouth and limit the degree of opening and closing of the mouth. It can help doctors perform operations better, ensure that the surgical site is fully exposed and stable, and prevent patients from closing their mouths unconsciously. For patients who are unconscious or require mechanical ventilation, a mouth fixator can help keep the airway open and prevent the tongue from falling back and blocking the airway, thereby forming a more stable surgical channel.

[0003] The existing technology has the following problems:

[0004] In terms of existing mouth fixation, an expander is usually inserted into the mouth and the mouth is expanded by the elasticity of the material. This fixation method will expand the patient's mouth to the limit that the patient can bear through the expander regardless of the size of the patient's mouth, causing discomfort to the patient and easily causing skin strain on the patient's mouth, resulting in low comfort of use. In addition, when fixing the size of the mouth, it is impossible to ensure the patient's breathing inside the mouth through additional tubes such as the trachea. When facing different users, the convenience of use is low. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods:

[0023] like Figure 1-5As shown, the utility model provides a mouth fixer, including a contraction fixing device 3, a plurality of mouth support strips 2 of different lengths are fixedly connected to the rear end of the contraction fixing device 3, a trachea fixing device 1 is fixedly connected to the upper side of the front end of the contraction fixing device 3, the middle part of the outer surface of the mouth support strip 2 is concave inward, the contraction fixing device 3 includes a support fixing frame 32, and a contraction control component 31 is rotatably connected to the middle part of the inner side of the support fixing frame 32.

[0024] The support and fixing frame 32 is the main structure of the contraction and fixing device 3, and its function is to support and fix the mouth support bar 2. The contraction control component 31 is used to control the contraction of the support and fixing frame 32, thereby adjusting the diameter of the mouth support bar 2 to adapt to the mouth size of different patients, and fix it through the recessed part of the mouth support bar 2 corresponding to the patient's teeth.

[0025] like Figure 2 As shown, the utility model provides a technical solution for a mouth fixer: preferably, the support and fixing frame 32 includes a lower outward expansion arm 323, the left end of the lower outward expansion arm 323 is rotatably connected to the upper outward expansion arm 322, and the right ends of the upper outward expansion arm 322 and the lower outward expansion arm 323 are rotatably connected to the support expansion arm 321, the support expansion arm 321, the upper outward expansion arm 322 and the lower outward expansion arm 323 have the same curvature, and the support expansion arm 321, the upper outward expansion arm 322 and the lower outward expansion arm 323 are unfolded to form a circle, and the front ends of several mouth support bars 2 are fixedly connected to the rear ends of the support expansion arm 321, the upper outward expansion arm 322 and the lower outward expansion arm 323 respectively.

[0026] The support expansion arm 321, the upper outward expansion arm 322 and the lower outward expansion arm 323 have the same curvature. When they are unfolded, they can form a circle. Through the action of the contraction control component 31, the angles between the lower outward expansion arm 323, the upper outward expansion arm 322 and the support expansion arm 321 can be changed, thereby realizing the contraction or expansion of the support fixing frame 32. When the support fixing frame 32 expands, the mouth support bar 2 is unfolded accordingly, and the degree of fixation of the mouth can be adjusted. This design can be adjusted according to the mouth size of different patients, thereby improving the applicability and comfort of the mouth fixer.

[0027] like Figure 2-3As shown, the utility model provides a technical solution for a mouth fixer: preferably, the contraction control component 31 includes a support block 311, and a rotating shaft 312 is fixedly connected to the middle part of the support block 311 from front to back, and the outer surface of the rotating shaft 312 is rotatably connected to the lower outward expansion arm 323 and the left end of the upper outward expansion arm 322. The right end of the support block 311 is rotatably connected to the rotating threaded rod 313, and the outer surface of the rotating threaded rod 313 is threadedly connected to the support adjustment block 316. The upper and lower ends of the support adjustment block 316 are fixedly connected to the adjustment moving block 315, and the adjustment moving block 315 is fixedly connected to the support moving shaft 314 from front to back, and the outer surface of the support moving shaft 314 is rotatably connected to the end of the support expansion arm 321 that is not connected to the lower outward expansion arm 323 or the upper outward expansion arm 322, and the right end of the rotating threaded rod 313 is fixedly connected to the adjustment knob 317.

[0028] The support block 311 plays the role of supporting and connecting other components. The rotating shaft 312 in the middle allows the lower expansion arm 323 and the upper expansion arm 322 to rotate around the rotating shaft 312. When the rotating threaded rod 313 rotates, the support adjustment block 316 will move along the axial direction of the supporting expansion arm 321 under the restriction of the rotating threaded rod 313. When the support adjustment block 316 moves, it will drive the supporting expansion arm 321 to move through the adjusting moving block 315 and the supporting moving shaft 314. The adjusting knob 317 is used to control the rotation of the rotating threaded rod 313.

[0029] like Figure 4 As shown, the utility model provides a technical solution for a mouth fixer: preferably, the trachea fixing device 1 includes a fixing plate 11, the rear end of the fixing plate 11 is fixedly connected to the upper side of the front end of the support block 311, which plays the role of fixing and supporting the entire trachea fixing device 1, and the lower side of the fixing plate 11 is fixedly connected to the support plate 13, which provides an installation basis for the fixing component 12, and the front end of the support plate 13 is fixedly connected to the fixing component 12 for fixing the trachea, and a through hole is opened in the middle of the support plate 13.

[0030] like Figure 4-5 As shown, the utility model provides a technical solution for a mouth fixer: preferably, the fixing component 12 includes a threaded movable groove 128, the threaded movable groove 128 is opened in the middle of the front end of the support plate 13, and sliding grooves 125 are opened on the upper and lower sides of the threaded movable groove 128, and a movable fixed block 124 is slidably connected in the sliding groove 125, and a fixing ring 126 is fixedly connected to the opposite sides of the two movable fixed blocks 124, and a guide movable column 123 is fixedly connected to the middle of the front end of the sliding groove 125, and threaded movable blocks 127 are threadedly connected on the left and right sides of the threaded movable groove 128, and the front ends of the two threaded movable blocks 127 are commonly fixedly connected to a fixed rotating ring 121, and two guide grooves 122 running through the front and back are opened on the outside of the fixed rotating ring 121, and the outside of the guide movable column 123 slides on the inner side of the nearest guide groove 122.

[0031] like Figure 5 As shown, the utility model provides a technical solution for a mouth fixer: preferably, the two guide grooves 122 are arc-shaped extending from the inner side of the fixed rotating ring 121 to the outer side, the two guide grooves 122 are symmetrical with the center of the fixed rotating ring 121 as the center, the fixed ring 126 is semicircular, and the two fixed rings 126 can form a circle on the side away from the movable fixed block 124.

[0032] When the fixed rotating ring 121 is rotated, the guide moving column 123 will move under the guidance of the guide groove 122, thereby driving the movable fixed block 124 to slide in the sliding groove 125. Due to the restriction of the sliding groove 125, the movable fixed block 124 can only drive the fixed ring 126 to slide back and forth, thereby reducing the distance between the two fixed rings 126 and fixing the trachea and other pipelines. At the same time, the threaded moving block 127 can improve the self-locking performance through the threaded connection with the threaded moving groove 128, and the fixed rotating ring 121 will be driven by the thread to squeeze toward the movable fixed block 124 when fixing a pipeline of a specific size, and the contact with the movable fixed block 124 increases friction to prevent the fixed ring 126 from retreating.

[0033] The working principle of this mouth retainer is described in detail below.

[0034] like Figure 1-5 As shown, first put the mouth support bar 2 into the patient's mouth, rotate the adjustment knob 317 according to the size of the patient's mouth, and adjust the contraction of the support fixing frame 32 through the contraction control component 31 to make the mouth support bar 2 reach the appropriate diameter, and support the patient's teeth through the recessed part to ensure the fixation of the mouth shape. Then, if the trachea needs to be used, pass the trachea through the through hole in the middle of the support plate 13, rotate the fixed rotating ring 121, and make the guide moving column 123 drive the movable fixing block 124 to slide under the guidance of the guide groove 122, thereby reducing the distance between the two fixing rings 126 and fixing the trachea. During use, it can be adjusted according to tracheas of different diameters to ensure stable fixation.

[0035] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
