発明の名称 (英語) FIXATOR NEW
発明の概要(英語) Provided is a bone fixator capable of reducing risks to a human body and having a simple structure. This fixator (10) is provided with: pedicle screws (12, 14) fixed to first and second mounted portions (24, 26) of a bone, respectively; first and second vibration members (16, 18); and a rod (20). The first vibration member (16) is provided with a first screw (16a) comprising a right-hand thread, and fixed to the pedicle screw (12) so as to be able to vibrate. The second vibration member (18) is provided with a second screw (18a) comprising a left-hand thread, and fixed to the pedicle screw (14) so as to be able to vibrate. The rod (20) has a third screw (20a) at one end and a fourth screw (20b) at the other end. The third screw (20a) engages with the first screw (16a) and the fourth screw (20b) engages with the second screw (18a). The second vibration member (18), when receiving ultrasonic waves oscillated from the outside of the body, deforms while vibrating, and the rod (20) rotates while being pressed against by the second vibration member (18); accordingly, the distance between the pedicle screws (12, 14), that is, the distance between the first and second mounted parts (24, 26) is increased or decreased.
従来技術、競合技術の概要(英語) BACKGROUND ART
Curved or spine, is twisted to the left as scoliosis, a serious failure occurs in the internal organs is a possibility.In order to correct a twist of the curved spine, the spine of the inside of a human body, such as a metal shaft is fixed to the supporter of the spinal fusion has been performed.This auxiliary tool is positioned, of scoliosis until the state is improved, which is fixed to the body over a long period of time.Therefore, the growth of the patient and a treatment according to the situation, the length of the auxiliary tool needs to be changed.In the prior art, the auxiliary tool to the affected area with a scalpel has been opened for exchange, a large burden on the patient.
In recent years, such as an endoscope using a minimally invasive method of adjusting the length of the auxiliary device has been proposed.However, such as endoscopic surgery incision method may be a small load is required, breakage of the hard film covering the nerve there exists the risk of complications.So that the onset of a disease, an adjustment of the length of the auxiliary tool in the form of a plurality of times, and a greater risk of unacceptable.Therefore, without cutting a method of adjusting the length of the auxiliary tool is necessary.Does not require cutting of the non-invasive method of adjusting the length of the auxiliary tool such as, a magnetic field from the outside by means of the irradiation, contraction of the aid of the body has been known a technique (Non-Patent Document 1).Expands and contracts due to such a magnetic auxiliary tool, such as glowing rod as a product in any language, are used.
