Abstract
The present invention relates to a kind of medical apparatus and instruments, particularly a kind of Distraction Apparatus of reparing skin defect.It comprises two parallel fixed arms, the device of the spacing of scalable two fixed arms is provided with between two fixed arms, fixed arm is provided with cylinder and sewing needle fixation clamp, and the device of the spacing of scalable two fixed arms can be the threaded rod that cover has stage clip, also can be a rhizoid thick stick.This invention structure is simple, and easy to use, the wound caused skin is little, and treatment controllability is strong, and need not cut skin or flap from normal skin, and postoperative scar is less.
Description
(1) technical field
The present invention relates to medical instruments field, particularly a kind of Distraction Apparatus of reparing skin defect.
(2) background technology
Skin injury is a kind of complication common after limb trauma.Traditional Therapeutic Method is for utilizing Free Skin Graft or transposition of flap repair deficiency, and its shortcoming to be sacrificed for district's skin or soft tissue, and cicatrix is comparatively large, and transposition of flap technical requirement is high.According to " tension force-stress rule (lawoftensionstress; LTS) ": to continue to biological tissue, stable slow drawing-off, can stimulate or activate some histiocytic regeneration and active growth, the similar fetal tissue of its growth pattern, be identical cell division, namely control the tensile stress of tractive, bone and soft tissue renewable.The Ilizarov method being usually used in skin injury stretching treatment is penetrate Kirschner wire at the skin edge of wound both sides to connect external fixer by steel wire, the postoperative skin of traction gradually edge.Its shortcoming is that external fixer is huger, carries inconvenience; And need be fixed on skeleton by Kirschner wire or screw, add wound.
(3) summary of the invention
The present invention, in order to make up the defect of prior art, provides the Distraction Apparatus of the reparing skin defect that a kind of volume is little, confession district skin accurately, is not sacrificed in stretching, wound is little.
The present invention is achieved through the following technical solutions:
A kind of Distraction Apparatus of reparing skin defect, it is characterized in that: comprise two parallel fixed arms, the two ends of described fixed arm are provided with the device of the distance that can change between two fixed arms, and described fixed arm is provided with some sewing needle fixation clamps, and on described fixed arm, cover has slidably cylinder.
The described device changing distance between two fixed arms comprises the threaded rod be fixed therein on a fixed arm, the other end of described threaded rod is furnished with fastening nut after another root fixed arm passes, this fixed arm can move on threaded rod, on described threaded rod, cover has stage clip, and the two ends of described stage clip are separately fixed on two fixed arms.
The described device changing distance between two fixed arms is the leading screw of a band rotating handle, and leading screw is connected through axle turnable with another root fixed arm after a wherein fixed arm.
The elastomeric material of described cylinder high temperature high voltage resistant makes, and all the other all parts adopt medical stainless steel, aluminium alloy or titanium alloy material to make.
The invention has the beneficial effects as follows:
1, the range of activity in joint is not limited, and easy to carry.
2, the present invention is bound on limbs by latex tubing, and limits the distance between Distraction Apparatus and skin by cylinder, and fixing reliable, wound is very little.
3, the flight pitch on leading screw or threaded rod is accurate, and according to the distance adjustment precession speed needing stretching every day, treatment controllability is strong.
4, the soft tissue regenerated by stretching covers skin injury district gradually, and need not cut skin or flap from normal skin, postoperative scar is less.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Fig. 1 be the first embodiment of the present invention main TV structure schematic diagram;
Fig. 2 be the second embodiment of the present invention main TV structure schematic diagram.
In figure, 1 fixed arm, 2 sewing needle fixation clamps, 3 cylinders, 4 threaded rods, 5 fastening nuts, 6 stage clips, 7 leading screws, 8 rotating handles.
(5) detailed description of the invention
Accompanying drawing is specific embodiments of the invention.Be illustrated in figure 1 the first embodiment, the Distraction Apparatus of this kind of reparing skin defect, comprise two parallel fixed arms 1, the two ends of fixed arm 1 are provided with the device of the distance that can change between two fixed arms, every root fixed arm 1 is provided with three sewing needle fixation clamps 2, and for fixing sewing needle, on every root fixed arm 1, cover has two slidably cylinders 3, for limiting the distance of skin and Distraction Apparatus, cylinder 3 elastomeric material of high temperature high voltage resistant makes.
The device that can change the distance between two fixed arms comprises the threaded rod 4 be fixed therein on a fixed arm 1, porose on another root fixed arm 1, the diameter in this hole is greater than the diameter of threaded rod 4, fastening nut 5 is furnished with after the other end of threaded rod 4 passes from this hole, this fixed arm 4 can move on threaded rod 4, on threaded rod 4, cover has stage clip 6, and the two ends of stage clip 6 are separately fixed on two fixed arms 1.
Except cylinder 3, all the other all parts adopt and all adopt medical stainless steel, aluminium alloy or titanium alloy material to make, therefore can complete machine autoclave sterilization.
Figure 2 shows that the second embodiment, and the difference of the first embodiment is only the device of the distance that can change between two fixed arms, it is the leading screw 7 of a band rotating handle 8, leading screw 7 passes a wherein fixed arm 1 and is connected afterwards axle turnablely with another root fixed arm 1: can open a blind hole inside fixed arm 1, the end of leading screw 7 withstands in blind hole; Can also be hinged on fixed arm 1 by the end of leading screw 7, also can be other known methods that leading screw 7 axle is turned.
During use, according to the size of skin injury area, respectively subcutaneous tissue is penetrated by parallel with skin edge for several pieces of Kirschner wires in skin injury both sides, medical sutures be needled into subcutaneous and be close to outside Kirschner wire, each piece of sewing needle is fixed on fixed arm 1 by sewing needle fixation clamp 2, with binder or latex tubing etc., fixed arm 1 is tied up on limbs with fixing Distraction Apparatus, distance between two fixed arms 1 is regulated by tightening fastening nut 5 or rotating handle 8, thus shorten the distance of the skin edge of both sides, skin injury place, each 0.25mm, every day 3-4 time.
Except technical characteristic described in description, all the other technical characteristics are those skilled in the art's known technology.
