Physical therapy device helping patient to open mouth

Abstract

The invention provides a physical therapy device helping patients (who suffer a head and neck neoplasm radiotherapy, burn, an oral and maxillofacial surgery and the like) hard to open mouths to restore masticatory and language functions. The physical therapy device is composed of a body, a transmission part and a control part. The body comprises an upper shifting piece (1), lower shifting pieces (2) and a handle (3). The transmission part is a transmission flexible shaft (4). The control part comprises an adjusting rotary knob (5), a fixed handle (6) and a movable handle (7). Before use, the adjusting rotary knob (5) is rotated according to illness state. In use, the upper shifting piece (1) and the lower shifting pieces (2) which are in natural closed state are placed between upper and lower incisors, the handle (3) is held by one hand, and the fixed handle (6) and the movable handle (7) are held by the other hand. Once held, the movable handle (7) moves toward the fixed handle (6), allowing the upper shifting piece (1) and the lower shifting pieces (2) to be opened through the transmission flexible shaft (4), and accordingly the mouth is opened, and mouth functions are restored. The physical therapy device is applicable to the patients who have mouth opening difficulties and masticatory and language dysfunctions caused by the head and neck neoplasm radiotherapy, the burn, the oral and maxillofacial surgery and the like.

Description

technical field [0001] The invention relates to a medical device, which is specially used as an opening physical therapy device for patients with opening difficulties (caused by radiotherapy for head and neck tumors, burns, oral and maxillofacial surgery, etc.) to restore chewing and language functions. Background technique [0002] Radiation therapy for head and neck tumors, burns, oral and maxillofacial surgery, etc. can cause mandibular joint degeneration, jaw muscle disuse atrophy or muscle fibrosis, joint ankylosis and other sequelae. obstacle. At present, many scholars have conducted research in this area, emphasizing that active opening training should be carried out early after surgery, but due to the decline and loss of mandibular joint function, active opening training cannot be effectively implemented, so most patients are cured, but their mouths cannot open. opened. For the treatment of difficulty opening the mouth, there is currently no effective rehabilitatio...
