DETAILED DESCRIPTION

[0024] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0025] Embodiment:

[0026] As shown in Figs. 1 to 5 A mandibular support device for oral surgery, comprising a mandibular support 1 and a front neck support 3, a rear neck support 5 is arranged on the rear side of the front neck support 3, the mandibular support 1 with an arc structure is arranged above the front neck support 3, the mandibular support 1 is adjustably connected with the front neck support 3 through an adjusting mechanism 2, and the mandibular support 1 is adjustably connected with the front neck support 3 through a supporting mechanism 4 on the left and right sides.

[0027] The adjusting mechanism 2 comprises a hinged joint 21, an adjusting screw rod 22, a limiting baffle 23, a reset spring 24, a fixed plate 25, an adjusting knob 26 and a guide sleeve 27. The fixed plate 25 is horizontally fixed on the ring surface of the front neck support 3. A through groove 28 for the rotation of the guide sleeve 27 is formed in the fixed plate 25. The guide sleeve 27 is arranged in the through groove 28 and is rotatably connected to the inner wall of the through groove 28 through a pin shaft. The adjusting screw rod 22 is inserted into the guide sleeve 27. The adjusting knob 26 is screwed on the adjusting screw rod 22 at a position below the guide sleeve 27. The adjusting screw rod 22 is hingedly connected to the lower jaw support 1 through the hinged joint 21. A plurality of limiting baffles 23 are fixed on the ring surface of the adjusting screw rod 22. The reset spring 24 is sleeved on the adjusting screw rod 22 between the limiting baffles 23 and the guide sleeve 27. The adjusting mechanism 2 cooperates with the lower jaw support 1 to stably support the lower jaw of the patient, effectively solves the jaw fatigue problem caused by the long-time opening of the upper and lower jaws during the oral surgery, and accurately adjusts the position and angle of the lower jaw support 1, thereby reducing the possibility of the patient's unintentional movement of the lower jaw, reducing the risk of injury in the oral cavity and improving the operation effect.

[0028] In the embodiment, the lower jaw support 1 is arranged in an arc shape to fit the lower jaw. The design ensures that the lower jaw support 1 closely fits the lower jaw of the patient, provides stable support, and prevents the lower jaw support 1 from slipping or shifting during the operation, thereby ensuring the accuracy of the operation. The inner side of the lower jaw support 1 is pasted with a buffer cotton pad 11 to prevent the lower jaw support 1 from directly contacting the skin of the patient, reduce friction and irritation, and increase the comfort of the patient during use. The buffer cotton pad 11 can absorb and distribute the pressure of the lower jaw support 1 on the lower jaw, thereby reducing the pressure pain caused by long-term wearing. A plurality of air vents 12 are formed in the buffer cotton pad 11 and the lower jaw support 1 to facilitate air circulation in the lower jaw during the operation and reduce the discomfort of the patient.

[0029] In the embodiment, the support mechanism 4 comprises a ball joint 41, a support rod 42, a positioning piece 43, a support spring 44 and a sliding sleeve 45. The support rod 42 is arranged between the lower jaw support 1 and the front neck support 3. The upper end of the support rod 42 is hingedly connected to the lower jaw support 1 through the ball joint 41. The lower end of the support rod 42 is inserted into the sliding sleeve 45. The sliding sleeve 45 is vertically rotatably connected to the front neck support 3 through a pin shaft. The positioning piece 43 is fixed on the ring surface of the support rod 42. The support spring 44 is sleeved on the support rod 42 between the positioning piece 43 and the sliding sleeve 45. The two sets of support mechanisms 4 can simultaneously support the lower jaw support 1 from both sides to ensure the stability of the lower jaw support 1, thereby ensuring that the lower jaw support 1 can provide sufficient support during the operation to prevent shifting and shaking.

[0030] In this embodiment, the front cervical brace 3 and the rear cervical brace 5 are integrally elliptical in structure, which conforms to the natural curve of the human neck, providing better fit and support. The front cervical brace 3 and the rear cervical brace 5 are hingedly connected on one side and detachably connected on the other side through the magic tape 31, allowing quick connection and disconnection of the front cervical brace 3 and the rear cervical brace 5 through the hinge and the magic tape 31, facilitating wearing.

[0031] In this embodiment, a sponge neck pad 52 is attached to the inner side of the rear cervical brace 5, which closely fits the patient's neck curve, reducing direct contact between the neck and the rear cervical brace 5, and reducing discomfort that may occur from long-term wearing, significantly reducing the patient's neck fatigue.

[0032] In this embodiment, a rubber pad 51 is fixed to the outer ring surface of the rear cervical brace 5, which can stably support the rear cervical brace 5, increase the friction between the rear cervical brace 5 and the operating bed, prevent the rear cervical brace 5 from rotating and loosening, and thus ensure the stability of the support to the neck.

[0033] The working principle of the lower jaw support device for oral surgery is as follows:

[0034] In actual use, first, the front cervical brace 3 and the rear cervical brace 5 are worn on the patient's neck, and the two are quickly connected through the magic tape 31 to form a support structure that fits the neck curve. The sponge neck pad 52 on the inner side of the rear cervical brace 5 closely fits the patient's neck, providing comfortable support and reducing neck fatigue. The rubber pad 51 on the outer ring surface of the rear cervical brace 5 increases the friction between the rear cervical brace 5 and the operating bed, ensuring the stability of the device. Then, according to the condition of the patient's lower jaw, the height and angle of the lower jaw brace 1 are adjusted by rotating the adjusting knob 26, ensuring that the lower jaw brace 1 closely fits the patient's lower jaw, and the patient's lower jaw is stably supported by the lower jaw brace 1. In this process, the doctor drives the adjusting screw 22 to move up and down in the guide sleeve 27 by rotating the adjusting knob 26, and adjusts the height and angle of the lower jaw brace 1 by moving the adjusting screw 22 to adapt to different degrees of opening of the patient's lower jaw. The support mechanism 4 on the left and right sides is hingedly connected to the lower jaw brace 1 through the ball head hinge 41, providing flexible support. The lower end of the support rod 42 is inserted into the sliding sleeve 45, which is vertically rotatably connected to the front cervical brace 3, allowing a certain degree of vertical movement. The positioning piece 43 and the support spring 44 ensure the stable position of the support rod 42 in the sliding sleeve 45, while absorbing and buffering the force when the patient moves slightly.

[0035] Obviously, the above embodiments of the present application are only examples for clearly illustrating the present application, and are not intended to limit the embodiments of the present application, and for ordinary skilled in the art, on the basis of the above description, other different forms of changes or variations can be made, and all the embodiments cannot be exhausted here, and any obvious changes or variations derived from the technical solutions of the present application still fall within the protection scope of the present application.
