Implantable Meaning System

technical field

The invention relates to the field of meaning systems, in particular to implantable meaning systems.

background technology .

Hand trauma is one of the common traumas in our country. According to statistics, hand trauma accounts for more than 20% of the total number of surgical emergencies. Accounts for 40% of all orthopedic emergencies. Among them, the fingers are completely or incompletely missing the majority. In the process of man-machine operation in current industrial production, it is inevitable to cause traumatic damage to fingers, resulting in a decrease in production capacity and serious inconvenience to life. How to reduce the morbidity rate of these patients, improve their quality of life, and make them not disabled after being injured, has become a health issue of common concern to the society. Finger repair and reconstruction methods used to use surgical methods such as deepening of the tiger's mouth, skin tube transplantation and bone grafting, lifting and lengthening of the stump, finger transposition, and toe transplantation. In the 1960s, with the development of microsurgery, hand function reconstruction Some remarkable achievements have been made in the field, especially in recent years, with the improvement of material life and spiritual life, as well as the improvement of medical conditions and technology, patients with finger defects have put forward higher requirements for the repair and reconstruction of missing fingers. Doctors in surgery, plastic surgery and microsurgery are also constantly exploring and trying various new technologies, methods and materials. Inspired by the Branemark dental implant method, the basic data of the metacarpal and phalanx bones of Chinese people were obtained through autopsy and CT three-dimensional imaging technology. After it forms a firm combination with the residual finger, use computer rapid prototyping and 3D printing technology to prepare a personalized silicone finger that is symmetrical to the healthy finger for the patient. The defect is repaired, and finally an implant-style prosthesis with beautiful appearance and certain functions is formed. This implant-type finger prosthesis technology can not only solve the shape problem of single or multiple finger defects, but also restore the function of the hand to a certain extent, and has the existence of deep proprioception, which overcomes the traditional finger especially Reconstruction of multi-finger defects has the disadvantage of high cost, solves the difficult problem of repairing multi-finger defects, and has advantages that cannot be compared with traditional artificial fingers. It has broad application prospects and can produce good social and economic benefits at the same time.
