Intellectualized orthopaedics implant for reconstruction after centrum excision

Abstract

The invention discloses an intellectualized orthopaedics implant for reconstruction after centrum excision. The intellectualized orthopaedics implant comprises an outer sleeve and an inner sleeve, wherein the outer sleeve is provided with an opening in one end, and an end surface at the other end, and the inner sleeve is provided with an opening in one end, and an end surface at the other end; theopening end of the outer sleeve is mounted at the opening end of the inner sleeve in a sleeving manner; the outer sleeve is in clearance fit with the inner sleeve; a stress sensor is arranged in a gap between the outer sleeve and the inner sleeve; a stress sensor and a displacement sensor are arranged at a supporting component between the opening end of the inner sleeve and the outer sleeve; anda gravity sensor is arranged on the inner wall of the outer sleeve or the inner sleeve; a plurality of through holes are formed in the side wall of the outer sleeve and / or the inner sleeve, communicate with an inner cavity of the outer sleeve and / or the inner sleeve, and are formed in the periphery of the outer sleeve and / or the inner sleeve. According to the intellectualized orthopaedics implantdisclosed by the invention, under the situation that X-ray examination and CT examination are not performed, whether a patient is subjected to bone fusion or not can be accurately judged, the precision rate for judging bone fusion is increased, and the own position, the stress situation and the like of the orthopaedics implant after transplanting can be recorded and fed back.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an intelligent orthopedic implant used for reconstruction after vertebral body resection. Background technique [0002] After the implantation of the existing orthopedic implants, repeated X-ray and CT examinations are required to assist in judging whether the patient has achieved bone healing, and the patient needs to go to the hospital for multiple examinations. There are problems such as labor costs, time costs, economic costs, and radiation hazards. ; And there is a lack of records and feedback on the position and stress of orthopedic implants after implantation, as well as the patient's spinal movement, rehabilitation exercise time, rest time, and supine time. Contents of the invention [0003] The present invention aims to provide an intelligent orthopedic implant for reconstruction after vertebral body resection, which can accurately determine whether a patient has achieve...
