Craniocerebral three-dimensional plastic prosthesis with muscular pedicle window and preparation method thereof

Abstract

The invention discloses a craniocerebral three-dimensional forming restoration with a muscle base window. According to the craniocerebral three-dimensional forming restoration with the muscle base window, a medical three-dimensional forming material serves as a substrate, multiple mesh holes are formed in the substrate, the craniocerebral three-dimensional forming restoration with the muscle base window is provided with a smooth outline edge, a suitable individualized muscle base window three-dimensional structure is reserved for the skull defect zone muscular tissue of a patient at the edge, close to the base of skull, of an outline, the tissue combinations such as the muscles, the meninx and the brain which are attached to a skull defect zone are located at the inner side of the craniocerebral three-dimensional forming restoration with the muscle base window, the outline radian of the craniocerebral three-dimensional forming restoration with the muscle base window are formed with the consideration of the distribution condition of the tissue combinations such as the muscles, the meninx and the brain in the skull defect zone, so that it is guaranteed that the skull and the brain are repaired and protected together, and symmetry and beauty of the skull and the brain at the two sides are considered. Compared with the prior art, the craniocerebral three-dimensional forming restoration with the muscle base window has the following advantages that the internal environments such as brain blood supply and intracranial pressure maintenance are improved and recovery of the brain functions is facilitated.

Description

technical field [0001] The invention relates to a craniocerebral three-dimensional shaped prosthetic body and a preparation method thereof, in particular to a cranial brain individualized three-dimensional shaped prosthetic body with a muscular pedicle window and a preparation method thereof. Background technique [0002] Decompressive craniectomy has saved the lives of a large number of patients in clinical practice, but long-term large skull defects can cause damage to the cranial contents, which is not conducive to the recovery of the body, and the safety and appearance are seriously affected. Therefore, surgical repair of skull defects is a very common medical operation, and two methods of autogenous bone repair and artificial material reconstruction are usually used clinically at home and abroad. When the repair area is large, artificial materials are often used for reconstruction. Traditionally, materials such as plexiglass and silicone rubber are used. The advantage i...

Problems solved by technology

The three-dimensional cranial prosthesis with muscular pedicle window can be directly used in the repair of skull defects, so that the operation does not need to integrate the muscle, dura mater, even arachnoid mater, pia mater, brain tissue and other structures that have been fused into a complex and have been repaired. The established ecological internal environment is reconstructed. The operation only exposes the muscular pedicle along the subgaleal space of the flap, which is easy to operate, with less damage and less bleeding; the operation and anesthesia time is short, the patient's reaction is mild, and the postoperative recovery is fast; the cranial cavity is restored. Integrity, protection of cranial content and natural appearance, is conducive to improving the blood supply of the brain and maintaining the stability of the internal environment such as intracranial pressure, promoting the recovery of brain function and improving the quality of life of patients; solve the problem of traditional muscle-fascial extracranial bone repair The postoperative titanium mesh entraps the muscle, causing a series of problems such as restricted mastication and local pain, insufficient local plumpness in appearance, impact and destruction of the new intracranial environment, deformation and loosening of skull repair materials, etc.
