Mouth gag for rehabilitation exercise after oral cancer radiotherapy

Abstract

The invention relates to the technical field of medical instruments, in particular to a mouth gag for rehabilitation exercise after oral cancer radiotherapy. A threaded rod is movably connected to theouter surface of the middle of a supporting block, gears are engaged with the outer surfaces of the two sides of the threaded rod and located on the outer side of the supporting block, and a first connecting rod is movably connected to the outer surface of each gear; a push plate is movably connected to one end of each first connecting rod, a fixing shaft is fixedly connected to the outer surfaceof the supporting block and located on one side of each push plate, adjusting rods are movably connected to the two sides of the outer wall of each fixing shaft, a limiting spring is fixedly connected between the outer surfaces of the two adjusting rods on one side of the each push plate, a top plate is fixedly connected to the outer surface of each adjusting rod, and a jaw plate is fixedly connected to one ends of the two adjusting rods on one side of each push plate. Due to the fact that meshing between the threaded rod and the gears is easy to control, the threaded rod is rotated to enablethe opening and closing degrees of the oral cavity to be equal each time, over excitation action cannot be generated on the oral cavity, and the mouth gag can better adapt to the comfort degree of different people.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a mouth opener for rehabilitation exercise after oral cancer radiotherapy. Background technique [0002] Difficulty in opening the mouth is clinically mainly due to ankylosis of the temporomandibular joint caused by radiotherapy for nasopharyngeal cancer and oral cancer, organic lesions, etc., manifested as tightness, pain, narrowing of mouth opening, and even trismus when opening the mouth. As a result, it is difficult for patients to eat. Appropriate and targeted rehabilitation exercises and treatment and nursing measures can effectively improve local blood circulation and help patients restore normal labor-saving function of the oral cavity.

Problems solved by technology

[0003] Although the existing oral dilator has a certain degree of elasticity, its volume is still large after being folded and compressed, it is difficult to put it into the patient's mouth, and it increases the pain of the patient during the placement process. Objects, easy to produce fluid in the mouth, the existing mouth opener can not suck out the saliva in the patient's mouth, which makes the patient feel uncomfortable. Therefore, those skilled in the art provide a mouth opener for rehabilitation exercise after oral cancer radiotherapy to solve the above-mentioned problems. Questions raised in the background art
