Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary appliances, in particular to an oral cavity expansion and positioning device for nuclear magnetic resonance examination of oral patients. Background Art

[0002] At present, oral patients usually need to use a mouth opener to open their mouths during MRI examinations. However, the existing mouth openers have a single opening angle and cannot be flexibly adjusted, which reduces the convenience of use and increases the limitations of use. Therefore, personnel in this field have proposed a mouth opener for MRI examinations of oral patients.

[0003] CN216570253U discloses an oral cavity expander, but during use, the expander can only achieve an expansion effect, the patient's comfort is extremely poor, and the positioning effect cannot be achieved. Utility Model Content

[0004] The technical problem to be solved by the utility model is: how to improve the comfort of patients during examination and provide an oral magnetic resonance positioning device.

[0005] In order to achieve the above object, the utility model is realized by the following technical solutions:

[0006] The oral magnetic resonance positioning device comprises an upper jaw support and a lower jaw support which are arranged in parallel, and a plurality of adjustment holes are arranged on opposite sides of the upper jaw support and the lower jaw support and along the axial direction, and the adjustment holes are arranged correspondingly, and adjustment pressure plates are arranged in the corresponding adjustment holes; and the interiors of the upper jaw support and the lower jaw support face the throat, and the exteriors of the upper jaw support and the lower jaw support are respectively hingedly connected to one end of an operating rod, and the other ends of the two operating rods are hinged together through a hinge shaft, and the hinge shaft is located outside the oral cavity.

[0007] The upper jaw support and the lower jaw support both include a support outer shell and a grease-like object filled in the support outer shell, and the support outer shell is made of TPU material.

[0008] The cross-section of the support outer shell of the upper jaw support and the lower jaw support is rectangular.

[0009] The adjusting pressure plate adopts a telescopic joint structure, and the telescopic joint structure is wrapped with latex.

[0010] Adjustment plate, operating lever and articulation axis are made of plastic.

[0011] Compared with the prior art, the utility model has the following beneficial effects: the height and width can be adjusted according to the patient's oral condition, improving the patient's comfort. In addition, the pit structure of the occlusal part facilitates the patient's occlusal positioning, so that the oral teeth are protected and stable during the examination, which is conducive to fixing the tongue and clearly showing the relationship between the tongue and adjacent structures for magnetic resonance scanning. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is the front view of the utility model. DETAILED DESCRIPTION

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0015] like Figure 1 As shown, the oral magnetic resonance positioning device includes an upper jaw support 1 and a lower jaw support 2 arranged in parallel, and a plurality of adjustment holes are arranged on the opposite sides of the upper jaw support 1 and the lower jaw support 2 along the axial direction, and the adjustment holes are arranged correspondingly, and an adjustment pressure plate 3 is arranged in the corresponding adjustment hole, so that the adjustment pressure plate 2 is located between the upper jaw support 1 and the lower jaw support 2, and the adjustment pressure plate 2 is used to press the tongue 4. The inside of the upper jaw support 1 and the lower jaw support 2 faces the throat, and the outside of the upper jaw support 1 and the lower jaw support 2 are respectively hinged to one end of the operating rod 6, and the other ends of the two operating rods 6 are hinged together through a hinge shaft 7, and the hinge shaft 7 is located outside the oral cavity.

[0016] Furthermore, the upper jaw support 1 and the lower jaw support 2 both include a support outer shell and a grease-like object 5 filled in the support outer shell, and the support outer shell is made of TPU material so as not to damage the upper and lower jaws.

[0017] Furthermore, the cross-section of the bracket outer shell of the upper jaw bracket 1 and the lower jaw bracket 2 is rectangular, so that the contact between the bracket outer shell and the upper and lower jaws is surface contact, which improves the comfort of the patient.

[0018] Furthermore, the adjusting pressing plate 3 adopts a telescopic joint structure, and the telescopic joint structure is wrapped with latex.

[0019] The working principle of the utility model is:

[0020] When a patient needs to undergo an oral MRI examination, the medical staff operates the operating lever 6 to adjust the telescopic structure of the adjusting plate 3 according to the size of the patient's mouth that can be opened, so that the distance between the upper jaw support 1 and the lower jaw support 2 is suitable for the opening of the patient's mouth. In addition, according to the range of the patient's tongue that can be extended, the position of the adjusting plate 3 relative to the upper jaw support 1 and the lower jaw support 2 is adjusted (adjustment holes in different positions are selected).

[0021] The positioning device of the utility model is placed in the patient's oral cavity so that the upper jaw support 1 and the lower jaw support 2 respectively press against the upper and lower jaws of the patient. At the same time, the adjustment pressure plate 3 is placed above the tongue so that the adjustment pressure plate 3 can press the patient's tongue, which is conducive to fixing the tongue and clearly showing the relationship between the tongue and the adjacent structure for magnetic resonance scanning.

[0022] It should be noted that the adjusting pressure plate 3, the operating rod 6 and the hinge shaft 7 in the present invention are all made of plastic.

[0023] The utility model has the following beneficial effects: the height and width can be adjusted according to the oral condition of the patient, thereby improving the comfort of the patient.

[0024] The above is only a preferred embodiment of the present invention. It should be pointed out that those skilled in the art can make several changes and improvements without departing from the overall concept of the present invention, and these should also be regarded as the protection scope of the present invention.
