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, particularly relate to a kind of intramedullary bone and extend bone Filtting device.
Background technology
At the Therapeutic Method that long bone metaphysis extension osteotomy art is to research in limb lengthening at the beginning of 80, be applicable to the upper and lower limb shortened deformity in side caused by a variety of causes.Foreign well-known orthopedist Monticelli reports through metaphysis lateral osteotomy lengthening 30 example June nineteen eighty-three, and domestic Li Qihong orthopaedic medical treatment circle authority waits and also reported tibial metaphysis extension osteotomy art 50 example in 1986.
Prolongation or the cripetura method of locking hollow intramedullary needle have two kinds, one is provided with agnail in composite bushing device (scabbard formula intramedullary needle), when casing bit being arranged in the medullary cavity after osteotomy, by distance end intramedullary needle lock hole, skeleton after osteotomy is locked on casing bit, sews up the incision; Another kind is by external traction limbs, establishes barbed scabbard formula casing bit to be subjected to displacement in medullary cavity, and owing to being provided with agnail in casing bit, the result be subjected to displacement can only be extend limbs, and can not overcome agnail limbs are bounced back.
Summary of the invention
The present invention is exactly for the problems referred to above, and provide a kind of intramedullary bone to extend bone Filtting device, this device can make agnail stretch as required.
For solving the problems of the technologies described above, a kind of intramedullary bone provided by the invention extends bone Filtting device, comprise a composite bushing device and and can close the capping of composite bushing device by screw, described composite bushing device comprises a sleeve pipe and is connected to the hollow intramedullary needle in sleeve pipe, also comprise a remote control type electric retractor device, described hollow intramedullary needle surface is provided with the downward agnail that two rows be subtend, symmetry, and the size of described agnail is 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 comprise a remote control unit and a rotary electric machine, the angular transducer that described rotary electric machine is provided with and this rotary electric machine is electrically connected and remote-receiver, described rotary electric 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 end of hollow intramedullary needle; Described internal surface of sleeve pipe is provided with length first groove consistent with sleeve pipe and the second groove, and described first groove and the second groove symmetrically shape; The width of first, second groove described is greater than the width of agnail simultaneously.
After adopting above-mentioned technology, the invention has the advantages that, if hollow intramedullary needle in use occurs excessively to extend, certain angle can be rotated counterclockwise in vitro, can unlock, thus avoid, at overtime once, excessive prolongation occurs.
Accompanying drawing explanation
Shown in Fig. 1 is structural representation of the present invention.
Wherein: 1, capping; 2, sleeve pipe; 3, hollow intramedullary needle; 4, remote control type electric retractor device; 5, agnail; 6, remote control unit; 7, rotary electric machine; 8, angular transducer; 9, remote-receiver; 10, the first groove; 11, the second groove.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in more detail.
Illustrated from the structure chart of Fig. 1, a kind of intramedullary bone extends bone Filtting device, comprise a composite bushing device and and can close the capping 1 of composite bushing device by screw, the hollow intramedullary needle 3 that composite bushing device comprises a sleeve pipe 2 and is connected in sleeve pipe 2, also comprises a remote control type electric retractor device 4; Being provided with two rows in the face of hollow intramedullary needle table 3 is subtend, symmetrical downward agnail 5, and the size of this agnail 5 is for can along sleeve pipe 2 upward sliding, left-right rotation and can not slide downward.
Remote control type electric retractor device 4 is connected to the bottom of capping 1, the present invention also comprises remote control unit 6 and a rotary electric machine 7 simultaneously, the angular transducer 8 that this rotary electric machine 7 is provided with and this rotary electric machine 7 is electrically connected and remote-receiver 9, and rotary electric machine 7 upper end cassette is connected to remote control type electric retractor device 4 lower end, and rotary electric machine 7 lower end is connected in the upper end of hollow intramedullary needle 3; The inwall of sleeve pipe 2 is provided with length first groove 10 consistent with sleeve pipe 2 and the second groove 11, first groove 10 and the second groove 11 symmetrically shape; And the width of the first groove 10, second groove 11 is greater than the width of agnail 5.
In the middle of reality uses, if hollow intramedullary needle 3 in use occurs excessively to extend, namely when remote control type electric retractor device 4 has been reduced to certain position, rotary electric machine 7 can be manipulated by remote control unit 6 to rotate an angle and make agnail 5 enter the first groove 10, second groove 11, the size of rotational angle is known by remote control unit 6 by angular transducer 8, then makes remote control type electric retractor device 4 be elongated to Len req, makes hollow intramedullary needle 3 get back to desired location.
The above is only the preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle, can also make some improvement, and these improvement also should be considered as protection scope of the present invention.
