Description
Technical field
This utility model relates to a kind of Open mouth training apparatus, is specifically related to a kind of passive Open mouth training device.
Background technology
At present, to the limitation of mouth opening that causes behind some surgical operations, for example the remporomandibular joint postoperative contains arthroscope and open operation; Behind the fracture of mandible, condylar fracture especially; Behind the operation on mandible, especially after the operation of orthognathous and ramus of mandible tumor; And the limitation of mouth opening that situation causes behind some fascial space infection of maxillofacial regions etc., the initiative and the effect of Open mouth training vary with each individual voluntarily owing to the patient, so will influence the curative effect of treatment operation, for this reason, how improve the effect extremely attention of osteoarthrosis surgery always of patient's Open mouth training.At present, the representational mouth-gag of developed country of being popular in has three kinds: continue passive Open mouth training device (continuous passivemotion, CPM) and two manual mouth-gag, wherein, the effect that continues passive Open mouth training device (CPM) is the generation of avoiding situations such as joint accretion, ankylosis and amyotrophy, alleviating pain promotes the circulation of local joint blood circulation and joint fluid that swelling is disappeared.CPM advantage clinically is: it has overcome patient's difference of the initiative of Open mouth training voluntarily, help the patient to carry out Open mouth training, the auxiliary curative effect that realizes operation on joint, alleviate postoperative pain, prevent the generation and the recurrence of contracture outside interior adhesion of postoperative capsule and the joint, recover mouth opening to greatest extent.Its mechanism of action is: at first, CPM can increase the nutrition and metabolism activity of articular cartilage.Joint fluid is very important for the removing of harmful substance and slough in the metabolism of the nutrition of articular cartilage, chondrocyte, the articular cavity, passive activity can promote the secretion of synovial membrane and absorption and synovial fluid to permeate to cartilage, helps articular cartilage regeneration and functional rehabilitation.Secondly, CPM can stimulate and quicken the reparation of articular cartilage.Make the antigen-exposed of sealing behind the articular cartilage damage, contact the generation immunoreation with joint fluid, antigen antibody complex then can further damage articular cartilage, continuously active has increased the joint fluid metabolism, remove harmful substance, stimulate the proliferation of chondrocytes, and make that undifferentiated cell transforms to chondrocyte in the blood, participate in repairing articular cartilage; In addition, undifferentiated osteoprogenitor cell can be converted into chondrocyte, repairing articular cartilage through the motion stimulation in the osseous tissue; The movable adhesion that also helps to eliminate periarticular soft tissues, blood circulation promoting is accelerated tissue repair.At last, CPM can ease the pain.According to " pain sensation gate control theory ", because motion constantly is transferred to nerve centre with stimulus signal through the teleneuron of joint capsule, it can suppress uploading of pain sensation signal; The intracavity hydrops that occurs after the joint injury, pressure raise and the joint capsule overtension can cause pain, and cause articular cartilage dysbolismus, joint continuous passive motion can quicken the knuckle synovia circulation, help to eliminate swelling and pain.Therefore, the CPM treatment is worth promoting as the supplementary means of necessity of joint surgery postoperative.But also there are some obvious defects in the use of CPM: 1. machine costs an arm and a leg, and every price 7-8 ten thousand RMB are not that most of units accept; 2. 40 yuan/hour of training expenses (by the Shanghai standard), as training requirement by the U.S., every patient's total cost is many more than 1.8 ten thousand RMB, this obviously is to refuse to obey to close national conditions, and the average cost that our actual clinical is used is 800 RMB/every, differ from 22 times more than with the training standard of the U.S., this is an one of the main reasons that causes China and foreign countries' curative effect difference; 3. the patient needs train to hospital every day, brings time and economic added burden and inconvenience to the patient.
Summary of the invention
It is a kind of simple in structure that the purpose of this utility model will provide exactly, can reach the described a kind of passive Open mouth training device that continues passive Open mouth training.
For this reason, a kind of passive Open mouth training device that this utility model provides, it mainly comprises manual device and gag, and is connected in the connection tube between above-mentioned manual device and the gag.Wherein, described manual device is made of loam cake and lower cover, has one to connect fulcrum between described loam cake, the lower cover, also has the pump housing between described loam cake, the lower cover; Described gag is made of loam cake and lower cover, connecting spring by one between described loam cake and the lower cover connects, have the pump housing to connect between described loam cake and the lower cover, described loam cake and lower cover respectively be connected with a dens supporter up and down, on described dens supporter, the dens supporter liner can be installed.
Of the present utility modelly succeed in developing the national conditions that meet China, can not cause the high-quality passive mouth-gag of tooth and joint injury again,, can obtain excellent curative effect to improve the treatment of limitation of mouth opening rehabilitation of patients,
This utility model adopts hydraulic pressure and lever principle, in conjunction with modern material and processing technique, follow the strong point of external mainstream product, rely on the cooperation of producer of domestic corporation, design and produce the passive mouth-gag of high-quality hydraulic pressure voluntarily, with the blank of filling up domestic and international this field with benefit the people.
A kind of passive Open mouth training device that this utility model provides partial design and performance in theory is better than external like product, and it is embodied in: adopt hydraulic principle, during Open mouth training, make the stressed of facing evenly be unlikely to impaired; The conduction that hydraulicdriven another advantage is active force is all slowly carried out with discharging, than the dependence snap action power of China life-time service more help realizing training objectives, and can avoid the iatrogenic injury in stressed tooth and joint.
A kind of passive Open mouth training device that this utility model provides adopts lever principle, makes manual force when the strength of 1kg, and the active force of gag part just can reach the strength of 4kg, and so, the patient is very laborsaving, is convenient to realize long training requirement.
The design of the bite-block part in the mouth of a kind of passive Open mouth training device that this utility model provides is made up of metal and the soft bullet material of macromolecule, and metal is in order to strengthen its form, and the soft bullet material of macromolecule can make it and facing is fitted and protect facing.There is certain adjustability the central authorities coupling part, to adapt to different dental arch forms.Being connected to of soft bullet material of macromolecule and metallic plate is detachable, and the replaceable use of soft bullet pad of three kinds of different-thickness is arranged, with the needs of satisfied different training stages and the replacing after the wearing and tearing.
The size of the opening degree of a kind of passive Open mouth training device that this utility model provides has the intensity adjustments function of third gear, to adapt to the needs of different training period and different cases.
