specific Embodiment approach 1

[0018] Specific embodiment 1: The intelligent deformable method of the artificial prosthesis based on the shape memory polymer of this embodiment is performed according to the following steps:

[0019] 1. Shape the smart deformable prosthesis with shape memory, and then use its shape memory effect to fold and compress;

[0020] 2. After compression, it is driven by external stimulus to make it present a deformed and expanded state, and by adjusting the external stimulus drive to achieve a controllable arbitrary deformation state, that is, the intelligent deformability of the artificial prosthesis based on shape memory polymer is completed.

[0021] In the first step of this embodiment, the shaping, for example, the prosthesis for rhinoplasty is carved into an L shape, the prosthesis for mandible is carved into a half-moon arc, and the prosthesis for breast augmentation is hemispherical; the shaped state is regarded as an intelligence with shape memory The final shape of the deformabl...

specific Embodiment approach 2

[0024] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the smart deformable prosthesis with shape memory in step 1 is made of one or both of thermoplastic shape memory polymer and thermosetting shape memory polymer. Than the composition of the complex. Other steps and parameters are the same as in the first embodiment.

specific Embodiment approach 3

[0025] Specific embodiment three: This embodiment is different from specific embodiment one in that the material form of the smart deformable prosthesis with shape memory in step one is foam, block or expansion. Other steps and parameters are the same as in the first embodiment.

Abstract

The invention provides an intelligent deformable method for an artificial prosthesis based on a shape memory polymer, and belongs to the technical field of medical equipment plastic surgery implants. The method solves problems that an existing plastic artificial prosthesis implantation process has large trauma, and adjusting prosthesis states again is difficult. The method comprises: 1, shaping an intelligent deformable prosthesis which has shape memory, and folding and compressing the prosthesis; 2, performing external stimulation to drive so the prosthesis is in a deformed unfolded state, to complete. The intelligent deformable prosthesis with shape memory is a shape memory polymer with good biocompatibility and physiological inert, and implantation wound is small, recovery process is fast, risk is low, and pain of a patient is reduced. If the patient is not satisfied on a plastic state, the intelligent deformable prosthesis can be driven to continue to deform and unfold through external stimulation, and deformation recovery rate of the prosthesis is controlled, to obtain deformation states in different degrees, until the patient is satisfied on the plastic state. The method prevents risks of a secondary surgery, and reduces pain of the patient.

Description

Technical field [0001] The invention belongs to the technical field of orthopedic implants for medical devices, and specifically relates to an intelligent deformable method for artificial prostheses based on shape memory polymers. Background technique [0002] Since the ancient Indians used frontal flaps for nasal reconstruction and the two world wars in the first half of the 20th century, plastic surgery has gradually emerged and developed rapidly. With the continuous development of tissue transplantation and tissue substitute technology, plastic surgery continued to improve and develop. At first, it was just a simple deformity correction medical treatment method to ensure that patients obtain the necessary conditions for normal life. By the 1980s, the human body was beautiful. No longer regarded as a natural endowment, people began to use advanced technology to decorate and transform the human body on a large scale. [0003] Common plastic and cosmetic procedures include breast ...
