Technical field
This utility model relates to a kind of non-invasive achilles tendon lengthening device, is used for the treatment of the human body Achilles tendonshortening, belongs to the brace in the medical apparatus and instruments.
Background technology
Achilles tendonshortening is a kind of much orthopaedic diseases, its back group of muscle group that shows as human body shank position causes drop foot because of total length cripetura due to the reasons such as congenital reason, traumatic, muscle disease, suffers from foot and can not steadily land in walking and occur dragging the mud shape to walk lamely thereby make.The world pop classical way for the treatment of this disease is at the capable tens centimetres of longitudinal incisions of posterior leg, and heel string is cut off in the serpentine stringer, prolongs then and sews up.Calf can stay the otch cicatrix of tens centimeter length.In recent years, along with social development, living standards of the people improve year by year, and the operation with operation method increase human body height that occurs at present is called limb lengthening.Method by operation has prolonged the bone of shank, but heel string do not prolong, and people use classical way mostly usually, do an Achilles tendonlengthening after the treatment that prolongs bone finishes.The Xia Hetao doctor of Pekinese has created a kind of heel string drawbar extension art of carrying out simultaneously with prolongation bone, on patient's calcaneus, respectively cross one exactly as the thick metal needle of pencil-lead, be " Kirschner wire ", the traction bone in also drawbar extension the heel string of posterior leg.The advantage that this Xia Shi calcaneal traction prolongs art is: avoided the incision Achilles tendonlengthening to the operation misery that patient brings, shortened treatment time, also avoided the big cicatrix of tens centimeter length that postoperative occurs on the shank.This also makes the Xia Shi transcalcaneal traction become the Therapeutic Method of present treatment Achilles tendonshortening wound minimum
But also there are some shortcomings in it: pass bone marrow matter and skin communicates for a long time with the external world as Kirschner wire.Truly have just in case infection occurs to cause myelitic danger, postoperative is pulled out Kirschner wire, and the rear heel both sides still have four bean shape cicatrixes clearly altogether.
Summary of the invention
The purpose of this utility model is to overcome the weak point in the background technology and provides a kind of easy to use, to the limbs not damaged, the postoperative limbs do not have cicatrix in the art, and it is reliable to be perfectly safe, there is not the worry of infection and osteomyelitis in the therapeutic process, the non-invasive achilles tendon lengthening device that the patient takes like a shot
What the purpose of this utility model was achieved in that it comprises two both sides that are installed in shank and foot is similar to right angled triangle support, increased pressure board, foot mould, pressurized handgrip, ratchet, semilune sour jujube plate.With collude, strand, string show the position explanation.Two right angle trigonometry support thigh limits are fixed bar, and two personal share limits are positioned at shank two rear sides, and far-end fixes by fixed axis and crisperding, can translation-angle, and each links to each other near-end by hold-down nut with the string limit separately.Burst limit is connected to a fixed by draw-in groove, snap ring and limb lengthening device or the fixed screw and the shank that are fixed in shank Gypsum Fibrosum and the fixture, and can mount and dismount easily.Two right angled triangle string limits are for supporting locating rod, its near-end is straight tabular sour jujube plate stem, far-end is for being the semilune sour jujube plate of its outer marginal zone deltoid spine of arc of mid point with the ankle joint position, and near-end is connected to the angle with a strand limit near-end, and far-end fixes with Spina jujubae on the sour jujube plate and the ratchet on the crisperding.Two right angled triangle crisperdings are pressure rod, and fixedly one flat plate is an increased pressure board therebetween, put a foot mould that matches with patient's sole on the plate, and in a word, the effect of crisperding is the pressurization of implementing foot.And this gradual pressurization is to carry out persistent pressure in the fixed mode of ratchet by the pressurization spanner handle of crisperding upper end again after near-end pressurization appropriateness.
The purpose of this utility model can also realize by following technology:
Two metal right angled triangles are connected as a body by increased pressure board and pressurization spanner at the crisperding two ends.During use with the draw-in groove on the thigh limit, two fixed screws on the stator in the shank Gypsum Fibrosum fix the snap ring spiral-lock at limb lengthening device or spiral-lock, make the ready-made foot mould that matches with patient's both feet in advance and place both feet increased pressure board top down, increased pressure board is fixed on the pressure rod of crisperding, the upper end of bar is the pressurization spanner, to human body near-end pulling pressurization spanner, ratchet can slide on semilune sour jujube plate, the angle on crisperding and burst limit will inevitably diminish, the foot mould produces pressure to foot, mainly concentrate on the toe and the sole of far-end,, reduced pressure thereby just strengthened lifting surface area because foot mould and each position of foot palm surface all coincide, when the spanner pressurization causes an amount of position, (patient does not produce pain and is degree) unclamped ratchet and promoted handle, and ratchet falls to being stuck on the semilune sour jujube plate, this moment, foot mould position was fixed, and brace is the persistent pressure state.During the sole pressurization, foot and shank angle diminish, and the heel string of posterior leg is elongated, and when continuing to elongate, human body produces the adaptability growth and prolongs, and reaches therapeutic purposes.Hold the pressurization spanner when needing pressure relief and ratchet is promoted handle mention, ratchet moves away semilune sour jujube plate, and crisperding is removed with a strand limit fixed relationship, and brace is removed the pressure of foot thereupon.By physiological requirement, every day, each one or two hours to the foot pressurization for several times, each between blanking time greater than guaranteeing that the unlikely generation in sole pressurized position weighs wounded, downright bad phenomenon pressing time, can put functional position and fix night.
