Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and specifically relates to an oral medical expander. Background Art

[0002] In surgical nursing, the use of an oral splint is relatively common. One type of oral splint uses a spring and a clamping block between relatively sliding sleeves to open holes, thereby adjusting the distance between the upper and lower jaw plates of the oral splint. However, the size of the mouth opening that can be opened varies from patient to patient, and there is a distance between the multiple holes used for clamping. This results in low accuracy in adjusting the distance between the upper and lower jaw plates, resulting in poor effectiveness of the oral splint.

[0003] Utility model patent publication number CN215017067U discloses a spreader for oral surgical care. The spreader uses a spring and a clamping block between relatively sliding sleeves to open holes, thereby adjusting the spacing between the upper and lower jaw plates of the oral spreader. However, different patients can open their mouths to different sizes, and there is a spacing between the multiple holes used for clamping. This results in low accuracy in adjusting the spacing between the upper and lower jaw plates, resulting in poor performance of the oral spreader. In view of this, the present utility model is proposed. Utility Model Content

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0026] like Figures 1 to 5 As shown, an oral medical expander includes a tooth sleeve 1, a connecting part 2 and a limiting part 3.

[0027] Specifically, the gear sleeve 1 is composed of an upper gear sleeve and a lower gear sleeve. Rubber strips 11 are bonded on both sides of the opening side of the gear sleeve 1. Connecting sleeves 12 are fixed at both ends of the other side of the gear sleeve 1. Linear slide grooves 14 are opened on both sides of the inner wall of the connecting sleeve 12. A groove 15 is opened on the other side of the inner wall of the connecting sleeve 12. The groove 15 is located on the inner wall of the opening of the connecting sleeve 12. A screw groove 16 is opened in the middle of the bottom of the groove 15.

[0028] More specifically, the connecting member 2 is located between two adjacent connecting sleeves 12, and the two adjacent connecting sleeves 12 are connected by a sealing belt 13. The setting of the sealing belt 13 plays a sealing role to prevent foreign matter in the oral cavity from entering the connecting sleeve 12 and affecting the relative movement of the connecting member 2 and the connecting sleeve 12. The sealing belt is sleeved on the outside of the connecting member 2, and the connecting member 2 includes a connecting rod 21. The two ends of the connecting rod 21 are respectively inserted into the two connecting sleeves 12. Both ends of the connecting rod 21 are connected to a spring 22, and the spring 22 is located in the connecting sleeve 12. The setting of the spring 22 enables the upper and lower tooth sleeves to automatically open as the patient's mouth opens wider without the need for additional assistance. Sliders 23 are fixed on both sides of both ends of the connecting rod 21. The sliders 23 are located in the corresponding linear slide grooves 14, which play a guiding and limiting role to prevent the connecting rod 21 from rotating in the connecting sleeve 12 while not affecting the relative sliding of the connecting rod 21 and the connecting sleeve 12. A plurality of tooth grooves 24 distributed in a linear array are provided on the other side of both ends of the connecting rod 21.

[0029] More specifically, the limit member 3 is located on one side of the open end of the connecting sleeve 12, and is used to limit the connecting member 2 and the connecting sleeve 12 relative to each other. The limit member 3 includes a movable plate 31 arranged in the groove 15, and a plurality of tooth blocks 32 distributed in a linear array are fixed on one side of the movable plate 31. The tooth blocks 32 are adapted to the tooth grooves 24, which play a limiting role and can limit the connecting rod 21 and the connecting sleeve 12 relative to each other, and maintain the opening angle of the upper tooth sleeve and the lower tooth sleeve. The middle part of the other side of the movable plate 31 is movably connected to a screw rod 33 through a bearing. One end of the screw rod 33 passes through the screw groove 16 and is fixed with a knob 34. The knob 34 is located on the outside of the connecting sleeve 12, and the screw rod 33 is driven to rotate by the knob 34. The screw 33 cooperates with the screw groove 16 to drive the movable plate 31 to move in the groove 15, thereby controlling the limiting of the connecting rod 21 and the connecting sleeve 12.

[0030] When the device is working, first, the upper and lower tooth sleeves on the tooth sleeve 1 are kneaded together so that the upper and lower tooth sleeves are close to each other, then the tooth sleeve 1 is placed in the patient's mouth, and the patient's upper and lower teeth are respectively connected to the upper and lower tooth sleeves, and then the patient opens his mouth to the maximum, and the upper and lower tooth sleeves open with the patient's mouth under the action of the spring 22. At this time, the knob 34 is turned, and the knob 34 drives the screw 33 to rotate, and the screw 33 cooperates with the screw groove 16 to drive the movable plate 31 to move in the groove 15 until the tooth block 32 on the movable plate 31 engages with the tooth groove 24 on the connecting rod 21, and the connecting rod 21 is relatively limited to the connecting sleeve 12, and then the upper and lower tooth sleeves are limited, so that the upper and lower tooth sleeves cooperate to keep the patient's mouth open.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
