Abstract
The invention discloses an intramedullary bone extending bone transport device. The intramedullary bone extending bone transport device comprises a composite bushing device and a seal cover which can seal the composite bushing device through screws, the composite bushing device comprises a bushing and a hollow intramedullary needle which is connected with the inside of the bushing, the intramedullary bone extending bone transport device further comprises a remote control power-driven retractable device, a remote control device and a rotating motor, inverted thorns are disposed on surfaces of the hollow intramedullary needle, the remote control power-driven retractable device is connected with the bottom of the seal cover, a first groove and a second groove are formed in the inner wall of the bushing, the length of the first groove and the second groove is equal to that of the bushing, the first groove and the second groove are symmetrical, and meanwhile, the width of the first and second grooves is larger than that of the inverted thorns. By means of the intramedullary bone extending bone transport device, the hollow intramedullary needle can rotate counterclockwise in vitro for a certain angle if excessively extending occurs during usage and unlocking can be achieved, and thereby, excessively extending can be avoided during one-time extending.
Description
Technical field
The present invention relates to a kind of orthopedic medical device, more particularly, to a kind of intramedullary bone prolongation bone Filtting device.
Background technology
At the beginning of long tube bone metaphysis extension osteotomy art is 80 to limb lengthening in terms of research Therapeutic Method it is adaptable to
Side caused by a variety of causes upper and lower limb shortened deformity.Foreign well-known orthopedist Monticelli reported in June nineteen eighty-three
Through metaphysis lateral osteotomy lengthening 30, domestic Li Qihong orthopaedic medical treatment circle authority waits and also reported tibia in 1986
Metaphysis extension osteotomy art 50.
The prolongation of locking hollow intramedullary needle or cripetura method have two kinds, and one kind is in composite bushing device (in scabbard formula marrow
Pin) in be provided with agnail, bone marrow intracavity after casing bit is arranged on osteotomy, by far and near end intramedullary needle lock hole, will cut
Skeleton after bone is locked on casing bit, sews up the incision；Another kind is by external traction limbs, and bone marrow intracavity is provided with agnail
Scabbard formula casing bit be subjected to displacement, be provided with agnail due in casing bit, the result being subjected to displacement can only be extend limbs,
And agnail can not be overcome so that limbs is bounced back.
Content of the invention
The present invention is aiming at the problems referred to above, provides a kind of intramedullary bone to extend bone Filtting device, this device can make agnail root
Stretched according to needs.
For solving above-mentioned technical problem, a kind of intramedullary bone that the present invention provides extends bone Filtting device, including a compound sleeve
Pipe device and one can close the capping of composite bushing device by screw, and described composite bushing device includes sleeve and company
It is connected to the hollow intramedullary needle in sleeve pipe, also includes a remote control type electric retractor device, described hollow intramedullary needle surface is provided with two rows
In to, symmetrical downward agnail, the size of described agnail for can along sleeve pipe upward sliding, left-right rotation and can not
Slide downward；Described remote control type electric retractor device is connected to closure base portion, also includes a remote control unit and a rotary electric machine,
Described rotary electric machine is provided with and this rotary electric machine is electrically connected with angular transducer and remote-receiver, described rotation electricity
Machine upper end cassette is connected to remote control type electric retractor device lower end, and described rotary electric machine lower end is connected in the upper of hollow intramedullary needle
End；Described sleeve pipe inwall is provided with length first groove consistent with sleeve pipe and the second groove, and described first groove and second
Groove symmetrically shape；The width of described first, second groove is more than the width of agnail simultaneously.
After above-mentioned technology, if it is an advantage of the current invention that there is excessive prolongation in use in hollow intramedullary needle, can
With rotate counterclockwise certain angle in vitro, you can unblock, thus avoiding, in prolongation once, excessive prolongation occurs.
Brief description
Shown in Fig. 1 is the structural representation of the present invention.
Wherein：1st, cover；2nd, sleeve pipe；3rd, hollow intramedullary needle；4th, remote control type electric retractor device；5th, agnail；6th, remote control dress
Put；7th, rotary electric machine；8th, angular transducer；9th, remote-receiver；10th, the first groove；11st, the second groove.
Specific embodiment
With reference to the accompanying drawings and detailed description the present invention is described in more detail.
Illustrated from the structure chart of Fig. 1, a kind of intramedullary bone prolongation bone Filtting device, including a composite bushing device and
One can close the capping 1 of composite bushing device by screw, and composite bushing device includes sleeve 2 and is connected in sleeve pipe 2
Hollow intramedullary needle 3, also include a remote control type electric retractor device 4；Hollow intramedullary needle 3 surface be provided with two rows be in to, right
The downward agnail 5 claiming, the size of this agnail 5 for can along sleeve pipe 2 upward sliding, left-right rotation and can not be to downslide
Dynamic.
Remote control type electric retractor device 4 be connected to capping 1 bottom, the present invention also include simultaneously a remote control unit 6 and
One rotary electric machine 7, the angular transducer 8 that this rotary electric machine 7 is provided with and this rotary electric machine 7 is electrically connected with and remote control reception dress
Put 9, and rotary electric machine 7 upper end cassette is connected to remote control type electric retractor device 4 lower end, rotary electric machine 7 lower end is connected in sky
The upper end of heart intramedullary needle 3；Length first groove 10 consistent with sleeve pipe 2 and the second groove 11 are provided with the inwall of sleeve pipe 2, the
One groove 10 and the second groove 11 symmetrically shape；And the width of the first groove 10, the second groove 11 is more than the width of agnail 5.
Actually used central, if hollow intramedullary needle 3 occurs excessive prolongation in use, that is, remote control type electric stretches dress
Put 4 be reduced to certain position in the case of, can by remote control unit 6 manipulate rotary electric machine 7 rotate an angle make agnail 5
Enter the first groove 10, the second groove 11, the big I of rotational angle is remotely-controlled device 6 and is known by angular transducer 8, so
After so that remote control type electric retractor device 4 is elongated to Len req, make hollow intramedullary needle 3 return to desired location.
The above is only the preferred embodiment of the present invention it is noted that ordinary skill people for the art
For member, on the premise of without departing from the technology of the present invention principle, some improvement can also be made, these improvement also should be regarded as this
Bright protection domain.
