Description
The invention belongs to the medical hygienics field, relate to bone surgery set, particularly a kind of apparatus that is used for slowly prolonging the residual finger of hands.
Finger length forfeiture is common hand injury, and much more especially finger is damaged, hand outward appearance and the function of grievous injury the disabled, and influence psychology, the live and work of the disabled.The treatment of finger defect is to prolong residual finger length, recovers its outward appearance and function.The method of treatment finger defect has following several at present:
1, leather hose bone grafting method: need to form earlier chest or stomach tube, cross transplantation is in residual finger, and the three disconnected bases of a fruit in week back are also implanted autologous iliac bone.The finger of this method lengthening is thick too fat to move, numbness, and easily cold injury ulceration, and the bone piece of implantation often is absorbed gradually and causes the part of elongatedness to be lost.So the residual finger profile and the function of method prolongation are all unsatisfactory.This law more is not suitable for to refer to damaged treatment more.
2, transfer of skin flap bone grafting method: promptly replacing traditional leather hose with the band neurovascular flap, is the technological improvement to last method.Though can overcome the relevant shortcoming of the method for going up, skin donor site is big cicatrix because of bark fetching stays, and the implantable bone piece still partly loses the elongatedness of acquisition because of far-end absorbs, and influences late result, and this law is not suitable for to refer to damaged treatment more yet.
3, metacarpal bone once prolongs method: by metacarpal bone osteotomy and the residual finger of the disposable prolongation of bone grafting operation, this law elongatedness is limited, is only applicable to the treatment of thumb defect, is not suitable for other and refers to damaged and damaged treatments that refer to more.
4, free toe transplantation method: usefulness microsurgery method in finger stub, mainly is applicable to toe transplantation thumb reconstruction or singly refers to and reproduce.This law operation technique complexity, the specification requirement height often has the possibility of failure, and needs to sacrifice normal toes, does not refer to damaged treatment so still be suitable for more.
In a word, damaged for finger length, particularly how finger is damaged, still lacks ideal Therapeutic Method and apparatus.
Much more especially the new apparatus that the object of the present invention is to provide the residual finger of a kind of easy, safe and effective hands to prolong is applicable to that residual finger soft tissue condition singly refers to damaged, thumb defect preferably, to refer to damaged extended treatment.
The objective of the invention is to reach like this: dock with two screw rods respectively at the two ends by screwed pipe, forms the compact spiral drafting system.Every pair of spiral drafting system has the screwed pipe of four apertures, the single hole screw rod that is reverse thread and diplopore screw rod, three fixed screws and two nuts by one and forms.Cooperate a special-purpose wrench and Kirschner wire commonly used with Second Mate or more spiral drafting system, simply perform the operation, can bring into play its drawing-off effect slowly, make residual finger skin, tendon, blood vessel, nerve, periosteum etc. with every day 1-2 millimeter speed extend gradually.Treat 3-4 after week, implantable bone piece between metacarpal bone that retracts or phalanges can reach the purpose that prolongs the residual finger of hands.
Below in conjunction with description of drawings formation of the present invention and implementation method.

The present invention is a kind of tubulose spiral drafting system that the residual finger of hands prolongs that is used for, comprise screwed pipe, screw rod, nut, fixed screw and Kirschner wire, dock with diplopore screw rod 2 and single hole screw rod 6 respectively at the two ends that are characterised in that screwed pipe 4, promptly constitutes a bar-shaped spiral drafting system.The stage casing of screwed pipe 4 has four rotation holes 8 of circumference uniform distribution, and the two ends of screwed pipe 4 have the opposite female thread of rotation direction.Diplopore screw rod 2 and single hole screw rod 6 have the opposite female thread of rotation direction.Diplopore screw rod 2 and single hole screw rod 6 have the opposite external screw thread of rotation direction, and its screw thread matches with screwed pipe 4.Rotate screwed pipe 4, screw rod 2 and screw rod 6 are rightabout longitudinal tensile strain or shortening.Diplopore screw rod 2 far-ends have the pin hole 10 that a confession runs through Kirschner wire 17.Single hole screw rod 6 far-ends have the pin hole 10 that a confession runs through Kirschner wire 17.In the side of pin hole 10 purl screw 11 is arranged.Be used for the nut 3 and the nut 5 of limit screwed pipe 4 and screw rod 2 or screw rod 6, its screw thread matches with screw rod 2 or screw rod 6 respectively.The screw thread of the fixed screw 1 of fixation Kel's needle 17 usefulness matches with purl screw 11.This device institute part is all made with 2Cr13 type stainless steel material.To the rotation hole on the screwed pipe 48, be furnished with special-purpose wrench 16, be used for rotating screwed pipe 4, to regulate the total length of drafting system.
Referring to Fig. 1, install when of the present invention, earlier nut is screwed into screw rod, again single hole screw rod and diplopore screw rod are screwed into screwed pipe respectively, then fixed screw is screwed in the purl screw.Because two screw rods are reverse thread, when inserting rotation hole 8 rotation screwed pipes with wrench 16, screw rod promptly extends round about or shortens.
Referring to Fig. 1 to Fig. 4, designer of the present invention recommends following specification: screwed pipe long 9 is 90 millimeters.Single hole screw rod long 12 is 72 millimeters, and diplopore screw rod long 14 is 80 millimeters, both threaded portions, and promptly screw thread long 13 and screw thread are long by 15, are 60 millimeters.When screw rod all was screwed into screwed pipe, drafting system total length 7 was 160 millimeters; When back-outing, drafting system total length 7 can reach 240 millimeters, and its maximum development length is 80 millimeters.
Referring to Fig. 6, Fig. 7 and Fig. 5, use main points of the present invention are: make residual finger back of the body outside otch, cut periosteum, subperiosteum is peeled off, and appears the stump phalanges, crosses one piece of 2 millimeters thick Kirschner wire 17 at the phalanges far-end, blocks phalanges.This drafting system is transferred to shortest length, determines the radius position of threading a needle, parallel another piece Kirschner wire that pierces is installed drafting system of the present invention.The distance of drafting system two screw rods is transferred to the appropriate location.Postoperative available dedicated every day wrench 16 rotates screwed pipes 4, screw rod is in the other direction extends, and speed is 2 millimeters of 1-every day, thereby the residual finger phalanges that has blocked is separated, and its soft tissue prolongs along with drawing-off lentamente.After the drawing-off of certain hour, residual finger can obviously extend, and removes drafting system after reaching predetermined extending length, is implanted into the autologous ilium of respective length at isolating spatium interosseum, and 2-3 is the healing of ilium piece after the month, and residual finger is promptly effectively prolonged.
Referring to Fig. 8, thumb stump system prolongs with the first metacarpal bone osteotomy, for preventing that adductor pollicis makes the rotation of osteotomy piece in the drawing-off, needs to wear two pieces of Kirschner wires in that the metacarpal bone far-end is parallel, to eliminate rotating shaft.
Referring to Fig. 9, refer to when damaged that can install and overpay extender for maimed finger and prolong residual finger simultaneously, radius only need be worn one piece of Kirschner wire more.
The present invention has the following advantages and good effect:
1, the present invention is used for thumb reconstruction, residual finger prolongs, and method is simple, safety, does not namely need to transplant toes, and again without cutting skin flap, the part is a residual wire scar only. Prolongation refers to keep the former residual normal skin texture of making a comment or criticism, and feels good. On profile, quality, function, all be better than traditional leather hose bone grafting method and other finger lengthening arts.
2, the present invention can once prolong a plurality of residual fingers simultaneously, and this is that other fingers lengthen art can't be obtained.
3, adopt slow drawing-off to prolong residual finger, when having avoided metacarpal bone once to prolong art soft tissue is done too much peeling off, and can obtain more satisfied length.
4, use the present invention, adopt the subperiosteum osteotomy, kept the integrity of osteotomy place periosteum, periosteum is along with drawing-off also slowly elongation, and after the bone piece was implanted, because periosteal osteogenesis, long-term effect was reliable.
