Description

3D prints customization oral cavity gag

Technical Field

The invention relates to a 3D printing customized oral cavity mouth gag, in particular to a 3D printing customized oral cavity mouth gag which can be operated by one hand to easily dilate the oral cavity of a patient.

Background

Medical advances and advances have led to increased survival and longer survival in cancer patients, thus maintaining or improving the overall function and quality of life of cancer survivors in a multi-aspect mode of intervention is a key goal in cancer rehabilitation. Oral cancer patients are treated by surgical resection, chemotherapy and radiotherapy, and problems such as infection, malnutrition and the like are more likely to occur due to mouth opening difficulty (trismus) caused by tumors or fibrosis of soft tissues around the oral cavity generated after treatment and influence on oral cleaning and ingestion functions.

At present, the number of oral cancer patients in China is continuously increased, and aiming at the mouth opening difficulty of the patients caused by oral tumor infiltration or radiation irradiation and other groups with incomplete mouth opening, the intervention mode of the mouth opening difficulty is mainly oral rehabilitation training and is assisted by proper oral correction tools to carry out progressive extension training. The prior oral auxiliary appliance has the following disadvantages:

1. the patients often use wooden tongue depressors, and the number of tongue depressors is continuously stacked to increase the opening width of the oral cavity. Although this method is simple, it is dangerous to some extent, for example, the wood is a relatively hard material, which is liable to damage the tissues in the oral cavity, and if the force is applied too much, it is more likely to break, and further stabbing the tissues in the oral cavity.

2. The high cost price (a group of about 3 ten thousand yuan) and the very large volume of the compressible mouth gag imported from abroad affect the use will of patients.

3. The plate-mould steel mouth gag is very painful when being used by a patient, so that the patient often resists or avoids treatment due to the pain during hard rehabilitation, and the rehabilitation effect is further reduced.

Therefore, how to develop and improve the shortcomings of the conventional oral auxiliary device is to make the oral auxiliary device more convenient for users to use, have better safety and rehabilitation effects, and also have low cost and difficult damage, which is a goal of research and development needed in the related industries. Therefore, the user can not meet the requirement of the user in actual use.

The first engaging surface 131 is locally disposed on the outer surface of the first supporting portion 13, and may be formed in a wave shape or a slot shape, but not limited to this structure, because the first supporting portion 13 has the function of enhancing the external friction force, so as to improve the sealing stability of the supporting point during supporting, the structure having the function should be a technology that can be easily found by the technical concept of the present invention.

The second supporting member 20 includes a second body 21, a second pivot portion 22 and a second supporting portion 23, the second body 21 has a second space 211 therein, the second pivot portion 22 extends from one end of the second body 21, the first and second supporting

members

10 and 20 are pivotally connected to each other by the first and

second pivot portions

12 and 22, and the second supporting portion 23 extends from the other end of the second body 21 and can be inserted into the oral cavity of a patient and is matched with the first supporting portion 13 for opening and closing. The first supporting portion 13 and the second supporting portion 23 are in a mirror-reflected form, so that a second engagement surface 231 is also locally disposed on an outer surface of the second supporting portion 23, and may be formed into a wave shape or a wire groove shape, but not limited to this structure, because the second supporting portion 23 has an effect of enhancing an external friction force, so as to improve a sealing stability to a supporting point during supporting, the structure having the effect should be a technology that can be easily conceived by the technical concept of the present invention.

One end of the screw 30 is pivotally installed in the first space 111 of the first support 10, and the other end of the screw 30 can move to a multi-angle to abut against the second space 211 of the second support 20, and a nut 31 is screwed on the screw 30. The first body 11 has a base 112 disposed in the first space 111, the base 112 has a recess (not shown) formed therein, and one end of the screw 30 is disposed in the recess, so that the screw 30 is pivotally disposed in the first space 111 of the first support 10 via the base 112. Thus, a novel 3D printing customized oral cavity mouth gag 1 is formed by the above-mentioned disclosed structure.

In the present embodiment, the first and second supporting

portions

13 and 23 extend from the other ends of the first and

second bodies

11 and 21 to form a gradually flat strip supporting piece, and the first and second supporting

bodies

10 and 20 can be opened and closed at an arbitrary angle of approximately 180 ° by utilizing the structural characteristics that the rear ends of the first and second supporting

bodies

10 and 20 are pivoted to each other by the first and

second pivoting portions

12 and 22, and the second space 211 of the second supporting body 20 is larger than the first space 111 of the first supporting body 10, so that the first and second supporting

bodies

10 and 20 can move up and down when the nut 30 rotates, and the first supporting body 10 and the second supporting body 20 as the fixed end can be in a complete closed state or an open state with a desired opening degree. When the 3D printing customized oral cavity mouth gag is actually matched and applied to the oral cavity of a patient, the closed first and second supporting

parts

13 and 23 of the 3D printing customized oral cavity mouth gag 1 are firstly placed into the oral cavity, so that the upper and lower rows of teeth of the patient can be occluded on the first and second

occlusal surfaces

131 and 231 on the surfaces of the first and second supporting

parts

13 and 23, and the friction force of the patient during occlusion is enhanced through the local wavy or linear groove-shaped structure. At this time, the patient can rotate the screw cap 31 screwed on the screw rod 30 by one hand according to the requirement of the rehabilitation work, so that the screw rod 30 rotates, the screw cap 31 is screwed to generate the relative displacement with the screw rod 30, the second support body 20 is used as a fixed end, and the first support body 10 is upwards spread, so that the oral cavity of the patient can be easily expanded by one hand, and the oral cavity rehabilitation work of the patient is realized.

Please refer to fig. 3 and fig. 4, which are a schematic diagram of a second embodiment of the present invention and a schematic diagram of a third embodiment of the present invention, respectively. As shown in the figure: the present invention can be configured as the second and third embodiments in addition to the above-mentioned first embodiment, and the difference lies in that, considering the structural change of the oral cavity after the operation of the patient, in this embodiment, the first and second supporting

portions

13, 23 extend from the other ends of the first and

second bodies

11, 21 to form an arc-shaped supporting piece which is gradually flattened and wider, wherein one side edge of the front end of the first and second supporting

portions

13, 23 is bent outward to form an arc-shaped edge, so that the side edge has the function of occlusion supporting, as shown in fig. 3, the first and second supporting

portions

13, 23 are bent outward to form a first and second left arc-shaped edges 132, 232 of a bent arc-shaped shape at the left side edge, and as shown in fig. 4, the first and second supporting

portions

13, 23 are bent outward to form a first and second right arc-shaped edges 133, 233 at the right side edge.

The invention utilizes the hot door of the 3D printing manufacturing technology to accelerate the development of the customized medical material, and the 3D printing and the biomedical material are combined to provide new value for the customized medical material and are no longer high-price medical materials. The invention relates to a mouth occluder, which is an important auxiliary tool or medical material for correcting and protecting related oral medical treatment, and is specially designed according to the personal oral structure.
