Problems solved by technology

Although the histocompatibility and support strength of metal materials are better, in clinical applications, metal materials will produce stress shielding and lead to osteoporosis due to their high elastic modulus; the material itself cannot be degraded, and a secondary treatment is required after bone healing Surgical removal; the metal will be corroded physiologically, releasing toxic metal ions and causing tissue inflammation; the effect of bone bonding is not good, affecting the healing of bone tissue, etc.

Embodiment Construction

[0024] Typical embodiments embodying the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention is capable of various changes in different embodiments without departing from the scope of the present invention, and that the description and drawings therein are illustrative in nature and not limiting. this invention.

[0025] Such as figure 1 As shown, the bone plate main body 1 is in a circular shape, and can also be designed in a square, trapezoidal, elliptical, and other symmetrical and regular structures that can be easily tailored, all of which can achieve the purpose of the present invention. The bone plate is a 1 mm thick circular sheet with a radius of 10 mm. The plate body is made of polylactic acid material, the surface has a microporous structure, and antibacterial substances are loaded on it, and the diameter of the micropores on the surface is 0.1-5 μm. The surf...

Abstract

The invention provides a shapeable artificial bone plate. The shapeable artificial bone plate is made of biological absorbable materials. A bone plate body is round or square or trapezoid or the like and is of a symmetrical structure with a regular shape. The surface of the bone plate is coated with antibacterial materials. The bone plate is characterized by being capable of being shaped through heating during an operation. The shapeable artificial bone plate can be applied to a fenestration operation. According to the size of a window of a patient, the size of the bone plate can be customized, and postoperative infection and adhesion can also be effectively restrained.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a bone plate used for window covering after thoracolumbar fenestration surgery and a manufacturing method thereof. Background technique [0002] Lumbar intervertebral disc herniation, also known as lumbar annulus fibrosus rupture, is due to degeneration of the lumbar intervertebral disc, or external force causes the imbalance of pressure inside and outside the lumbar keyboard, causing intervertebral disc rupture and annulus fibrosus tissue to bulge, protrude or protrude, compressing and stimulating A series of symptoms and signs caused by the nerves in the spinal canal and the nerve roots in the intervertebral foramina. At present, hemilaminectomy and total laminectomy are mainly used in the treatment of intervertebral disc herniation, but these two methods seriously damage the three-dimensional stability of the lumbar spine operation segment, and the exposure range is large, the b...
