Description

Technical Field

[0001] The utility model relates to the technical field of joint repositioning auxiliary tools in the oral department, in particular to a temporomandibular joint repositioning auxiliary device. Background Art

[0002] Temporomandibular joint dislocation is a disease often encountered in the oral emergency department. Temporomandibular joint dislocation can occur on one side or on both sides. The most common clinical cases are acute anterior dislocation and recurrent anterior dislocation. When the patient's temporomandibular joint is dislocated, the condyle of the mandible slides out of the joint tubercle and cannot be repositioned by itself. At this time, the patient opens his mouth, cannot close it, drools, has difficulty eating and speaking, and feels extremely painful. For this type of temporomandibular joint dislocation, manual reduction is often used clinically. When the doctor performs the reduction, he first wraps the thumbs of both hands with soft objects such as gauze or paper towels, and places them on the occlusal surfaces of the second molars on both sides of the patient's mandible, and the remaining fingers are fixed in front of the mandibular margin and the mandibular angle notch. The patient is asked to relax, and the doctor presses down the back of the patient's mandible and lifts the chin, so that the condyle moves down to the bottom of the articular tubercle. When the condyle reaches the bottom and back of the articular tubercle, the patient's jaw elevator muscles reflexively contract automatically and quickly, causing the temporomandibular joint to return to the articular fossa, and the upper and lower teeth to return to the closed state. At this time, the rapidly closing teeth can easily bite the surgeon's fingers. In addition, the radial muscle contraction of such patients has a very strong bite force. Even with gauze wrapping, it is difficult to avoid the pain or even injury caused by the bite force. Therefore, a temporomandibular joint reduction auxiliary device is needed during reduction.

[0003] At present, doctors mostly use soft materials such as paper towels and gauze to wrap around the thumb for protection during reduction. This kind of protection has limited effect. Some devices can be put on the doctor's thumb for relatively stable and safe protection. However, when such devices are used, since they are put on the finger, during the reduction process, the thumb is quickly retracted out of the mouth, and the device and the thumb are easily separated, causing the protective body to be stuck in the patient's mouth, affecting the reduction effect, and failing to take into account both safety and ease of use.

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] The utility model provides Figure 1-Figure 3 The temporomandibular joint repositioning auxiliary device shown in the figure includes: a thumb sleeve 1, an extension part 12 is fixedly connected to the outer lower side of the thumb sleeve 1, and the extension part 12 is convenient for fixing the thumb sleeve 1 on the thumb; a protective sleeve 2, the protective sleeve 2 is fixedly installed on the outer side of the thumb sleeve 1, and the protective sleeve 2 is used to protect the external bite of the thumb sleeve 1; the connecting rope 3, the connecting rope 3 is fixedly installed at the bottom of the thumb sleeve 1, and the connecting rope 3 is used to pull and hang the thumb sleeve 1.

[0025] Furthermore, a damping layer 4 is fixedly connected to the inner side of the thumb cover 1. The damping layer 4 is made of sponge material. The damping layer 4 is used to protect the thumb on the inner side. At the same time, it can increase the connection tightness and friction between the inner side and the thumb, increase the difficulty of detaching the thumb cover 1 after it is fixed, and ensure the reliability of use.

[0026] Furthermore, gaps 5 for convenient deformation are provided on opposite sides of the outer sides of the thumb sleeve 1 and the protective sleeve 2. The gaps 5 can facilitate the deformation of the thumb sleeve 1 as the extension portion 12 is pulled, thereby improving the tightness of fixation.

[0027] Furthermore, friction pads 6 are fixedly mounted on one side of the outer lower side of the thumb sleeve 1 and on the adjacent side of the extension portion 12 , respectively. The friction pads 6 are used to increase the friction force at the connection after the thumb sleeve 1 and the thumb are fixed, thereby increasing the difficulty of separation.

[0028] Furthermore, a buckle 7 is fixedly connected to one side of the extension portion 12, a strip groove 8 is provided on the buckle 7, fixing holes 9 are provided on the upper and lower sides of one side of the buckle 7, and a clamping block 10 is fixedly connected to one side of the outer lower side of the thumb cover 1 at equal intervals and is symmetrically distributed up and down. The strip groove 8 is used to reduce the amount of material used, and the buckle 7 facilitates pulling the extension portion 12 to wrap around the outside of the thumb cover 1, and the fixing hole 9 can be buckled into the clamping block 10 at the corresponding position, so as to fix the buckle 7 at the current position.

[0029] Furthermore, one end of the connecting rope 3 is fixedly connected with a ring buckle 11 for hanging and holding. The ring buckle 11 can be used to hang on the outside of the nail-shaped object to hang the device, and it can also be convenient for the user to hold it for use.

[0030] Furthermore, a ball head is fixedly connected to the end of the block 10, and the maximum outer diameter of the ball head is greater than the maximum outer diameter of the rod of the block 10. The limited outer diameter can prevent the thumb cover 1 from separating from the extension part 12 after the buckle 7 is tied, thereby improving the reliability and stability of use.

[0031] Furthermore, a bite pad 13 is fixedly connected to one side of the outer side of the protective sleeve 2, and anti-skid grooves 14 are evenly distributed on the bite pad 13. The anti-skid grooves 14 are used to contact the lower teeth when the doctor's fingers are inserted into the patient's mouth, so as to increase the contact area and improve the friction.

[0032] When in use, the doctor first puts the device on the thumb so that the damping layer 4 is used to squeeze the thumbs against each other, then presses the outer lower side of the thumb sleeve 1, and pulls the extension part 12 to fit the outer lower side of the thumb sleeve 1 through the buckle 7, so that the friction pads 6 contact and squeeze each other, and then passes the fixing hole 9 on the buckle 7 through the block 10 at a certain position to complete the fixation of the device to the thumb. When performing a reduction operation on the patient, the doctor can wrap the ring buckle 11 around the palm or wrist through the connecting rope 3, and pull the thumb sleeve 1 outward through the connecting rope 3 when retracting the thumb outward, which can further prevent the thumb sleeve 1 from separating from the thumb during the reduction process, making the device both safe and reliable.

[0033] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
