Background technology
Long bone large segmental bone defect caused by osteomyelitis, bone tumour and open fracture, such as malpractice will seriously affect
The quality of life and labour capacity of patient.It is to treat the effective ways of bone defect that bone, which moves method,.At present conventionally by outer fixed dress
It sets and gives bone exact stability, take one section of bone living of bone defect upper and lower end, using the movable fixture on external fixing rack,
According to the work bone in set direction and frequency, the drawing interception of suitable speed, the regeneration potential of bone tissue is remotivated, is gradually filled out
Psoralen defect completes the reconstruction and reparation of limbs.
There are many complication, including pin site infection to be loosened with fixed pin during outer fixed bone is moved, soft tissue contracture,
Anchylosis, deformity and serious Soft tissue cutting pain etc., and incidence is higher, directly affects the process for moving treatment, very
To the functional rehabilitation for influencing limbs.How to effectively reduce related complication during bone is moved is still a stubborn problem.
Full merging controllable type intramedullary nail technology tentatively realizes internal distraction osteogenesis, but technique is difficult to complete greatly
The Limb lengthening operation of section bone defect, and it is expensive, it is clinically difficult to promote.
Therefore clinically there is an urgent need to a kind of internal marrow dermoskeletons of controllable type to move technology, and it is automatic thoroughly to realize that bone is moved
Change, is simplified controllableization；And expand the indication that internal bone moves technology significantly, advantage is improved, cost is reduced.
Invention content
The purpose of the invention is to provide a kind of internal marrow dermoskeleton Conveyer, reduction is treated using exterior fixing rack
Many complication, simplify bone move technology treatment more they tend to, painlessization, economization.
A kind of internal marrow dermoskeleton Conveyer by main body, sliding block, lock screw, motor, titanium cable, belt wheel, battery, wirelessly connects
Receiving apparatus, power receiving system, wireless charging pedestal and Digiplex composition；
Main body both ends offer multiple locking screw thread holes respectively, and lock screw is spun in locking screw thread hole, are set in the middle part of main body
It is equipped with groove, sliding slot is provided in the main body of groove both sides, the boss of sliding block both sides is placed in sliding slot, and sliding block can be along sliding slot
It is slided, locking screw thread hole and through-hole is offered on sliding block；Motor setting is in lower body, and there are one motor output end installations
Belt wheel, titanium cable passes through the through-hole on sliding block and both ends are separately fixed on belt wheel, which passes through radio receiver and battery
Connection, there are one power receiving systems for the connection of battery upper end, and power receiving system will be external to battery powered, wireless charging pedestal
Electric energy is transmitted to power receiving system, and Digiplex transmits a signal to radio receiver.
The operation principle of the present embodiment：
Bone Conveyer main body both ends are fixed on bone defect area both ends by lock screw bridge joint, osteotomy end is by locking spiral shell
Nail is fixed on sliding block, then carries out bone-culting operation operation, when needing to pull active bone block, presses Digiplex, battery to
Motor is powered, and belt wheel is rotated along single direction under motor driving, and belt wheel winds titanium cable around single direction therewith, and belt wheel often rotates
Once, length of the titanium cable on belt wheel is 0.25mm, and titanium cable can pull the active bone block for cutting end to distally moving 0.25mm,
Electrical axis can be automatically locked after the completion of rotation every time, be interrupted daily, rotate with having the rhythm and pace of moving things four times, titanium cable can pull the work blocked
Property bone block move 1mm to receiving terminal, the device by electrical axis machinery rotate, band movable belt pulley along single direction wind titanium
Cable, the active bone block that titanium cable can be interrupted, rhythmic drawing is blocked realize that bone moves skeletonization.
Beneficial effects of the present invention：
It is rotated using motor driven belts wheel, the movement of titanium cable tie movable slider, distraction osteogenesis is carried out to the active bone block of osteotomy, it is real
What existing bone was moved automates, controllably changes, simplifying, reducing the pain and family burden of patient, while decreasing medical matters people
The workload of member.
