Problems solved by technology

[0008] However, the shape of the protective sheath is customized according to the shape of the opening, which is not suitable for the specific conditions of the patient's teeth, and for the patient, the main body for applying force is still the opening arm of the gag, so this patent is still pending. Can solve the comfort problem of patients when using
[0009] In addition, in clinical applications, it is usually hoped that patients can take the gag home and use it regularly during rehabilitation. However, the existing gag has a long arm and is complicated to use, making it difficult for the patient to complete the gag independently. However, if a shorter moment arm is used, it will be very strenuous for the patient to use
[0010] Moreover, the existing mouth gags are usually integrated, and if a corresponding gag is customized for each patient's oral shape, the cost will be very high

Embodiment approach 1

[0094] The first embodiment of the present invention provides an opener, see figure 1 shown, including:

[0095] The upper alveolar covering part 1 can conform to the shape of the patient's upper alveolar;

[0096] The lower alveolar covering part 2 can conform to the shape of the patient's lower alveolar;

[0097] The gag also includes a stretching device 3, the top end of the stretching device 3 is against the upper alveolar covering 1, and the bottom end is against the lower alveolar covering 2, and the spreading device 3 is used to stretch the upper alveolar covering Part 1 and Lower Alveolar Covering Part 2.

[0098] When in use, put the upper alveolar covering 1 and the lower alveolar covering 2 into the patient's mouth in sequence, and then install the expansion device 3 between the upper alveolar covering 1 and the lower alveolar covering 2 , and finally the upper alveolar covering part 1 and the lower alveolar covering part 2 are stretched apart using the spreading...

Embodiment approach 2

[0104] The second embodiment of the present invention provides an opener. The second embodiment is a further improvement of the first embodiment. The main improvement is that, in the second embodiment of the present invention, see figure 2 As shown, the upper alveolar covering part 1 is provided with an upper abutment part 1a matching the shape of the top end of the distraction device 3;

[0105] The lower alveolar covering part 2 is provided with a lower abutting part matching the shape of the bottom end of the expansion device 3 .

[0106] By providing the upper abutting portion 1a and the lower abutting portion, the two ends of the stretching device 3 can be prevented from slipping when stressed, which improves the convenience of use.

[0107] Specifically, the upper abutting portion 1a and the lower abutting portion may have various forms. In this embodiment, see image 3 As shown, the upper abutting portion 1 a can be a groove sunken toward the inside of the upper alve...

Embodiment approach 3

[0111] The third embodiment of the present invention provides an opener. The third embodiment is a further improvement of the first and second embodiments. The main improvement is that in the third embodiment of the present invention, the upper abutment part The number of 1a and the lower abutting portion are three and arranged in pairs in one-to-one correspondence.

[0112] Specifically, see Figure 4 As shown, there is an upper abutting part 1a located at the position where the upper alveolar covering part 1 is opposite to the inner side of the patient's upper incisors, and the opposite lower abutting part is located at the position where the lower alveolar covering part 2 is opposite to the inner side of the patient's lower incisors Location;

[0113] There is an upper abutment part 1a located at the position where the upper alveolar covering part 1 is opposite to the inner side of the patient's upper left canine, and the lower abutting part is located at a position where ...

Abstract

The invention relates to the field of medical instruments and discloses a mouth gag. The mouth gag comprises a superior alveoli enclosing part, an inferior alveoli enclosing part and a spreading device, wherein the superior alveoli enclosing part can conform to the shape of superior alveoli of a patient; the inferior alveoli enclosing part can conform to the shape of inferior alveoli of the patient; the top end of the spreading device is propped against the superior alveoli enclosing part and the bottom end is propped against the inferior alveoli enclosing part; and the spreading device is used for spreading the superior alveoli enclosing part and the inferior alveoli enclosing part. The mouth gag is more comfortable to use and inferior in cost.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an opener. Background technique [0002] Mouth gag, also known as mouth gag, is a device used to open the mouth of a patient. There are two kinds of conventional mouth gags, one is to keep the oral cavity of general patients in an open state, and the other is to open the oral cavity of patients with difficulty in opening the mouth. [0003] For patients undergoing resection of oral and maxillofacial head and neck tumors, especially for patients undergoing tumor resection for cancers such as tongue cancer, floor of the mouth cancer, buccal cancer, upper and lower gingival cancer, and parotid gland cancer, the temporomandibular The joints are damaged to a certain extent, resulting in a significant reduction in the range of motion of the temporomandibular joints, and it is often difficult to open the mouth. Therefore need to use the opener of the second kind of function. [000...
