Technical Field

The invention relates to the field of finger correction, in particular to a finger joint bending injury orthopedic platform.

Background

The finger deformity correction is to correct certain finger adhesion phenomenon by means of operation.

Polydactyly is one of the most common congenital malformations. Some neoplastic indications are inherited, for example, those of the middle and small fingers indicate autosomal dominant genetic malformations. The deformity of the 4 th finger, the ring finger, the middle finger and the little finger, has unique manifestations. Complicated deformities such as mirror hand (ulnar side, both hands) and five long fingers also belong to the neoplastic finger deformity, and repeated deformities can be divided into radial (thumb side), medial and ulnar (little finger side) types.

And are also more common and can be divided into full and partial. Only soft tissue closure may also be referred to as simple syndactyly. The term "complicated" with bony connection refers to the condition of a complex finger. And the index is commonly seen between 3-4 fingers, and also in Apert syndrome (craniosynostosis, complex index of the hands or feet with varying degrees), banding deformity, and Poland syndrome (lack of pectoralis major and index).

More commonly, the bending fingers are deformed either to the frontal or sagittal plane, with localized bony deformities except for the bending fingers. Many children are complicated with different systemic diseases. The flexed finger (camptodactly) is a common curved finger and can be classified into infant type and juvenile type. The onset of the disease is mild in adolescent age 12-14 years old, and is common in women.

In addition, the optical fiber is a short term for optical fiber, and is a fiber made of glass or plastic, which can be used as a light transmission means. The principle of transmission is 'total reflection of light'. The fine optical fiber is enclosed in a plastic sheath so that it can be bent without breaking. Generally, a Light Emitting Diode (LED) or a laser beam is used as a transmitter at one end of the optical fiber to transmit an optical pulse to the optical fiber, and a photosensor is used as a receiver at the other end of the optical fiber to detect the pulse.

In the multimode optical fiber, the core diameter is 50 μm and 62.5 μm, which are approximately equivalent to the thickness of human hair. Whereas the diameter of the single-mode optical fiber core is 8 μm to 10 μm, 9/125 μm is generally used. The core is surrounded by a glass envelope, commonly referred to as a cladding, of lower refractive index than the core, which keeps the light rays within the core. Further on the outside is a thin plastic outer jacket, i.e. a coating, for protecting the cladding. The optical fibers are typically bundled and protected by an outer jacket. The core is usually a double-walled concentric cylinder of silica glass with a small cross-sectional area, which is brittle and easily broken, and therefore requires the addition of a protective layer.
