Description

Intoe corrective shoes

Technical field

The present invention relates to foot health article fields more particularly to one kind to help to correct and prevent foot Hallux valgus Shoes.

Background technology

Hallux valgus refers to that deflection shifts big toe outward at Metatarsophalangeal joint.Intoe is a kind of solution of complexity Deformity is cutd open, and extremely challenging in the treatment.Thumb capsule refers to the apparent inside protrusions occurred in Hallux valgus, but one As in the case of the two nouns be used interchangeably.Intoe is to involve the most common lesion of big toe, is more common in middle aged and aged women, Genetic predisposition is occurred most often at plus the people for wearing inappropriate shoes for a long time, inappropriate shoes can apply big toe abnormal Pressure.Thumb is stiff to normally behave as big toe deflection outward at Metatarsophalangeal joint, occurs apparent spur on the inside of joint, and one At a little patient's spurs soft tissue because for a long time by shoes friction and Extrusion due to there is red and swollen, hydrops, referred to as bunion.Serious intoe is suffered from Person may occur in which the deflection of other toes, ride.Patient with intoe, which differs, has established a capital pain, and deformity also with pain not It is directly proportional.The main reason for pain generates be oppress after thumb caput metatarsale medial eminence and friction and cause acute bunion.Thumb plantar Toe joint is abnormal for a long time, osteoarthritis occurs, the callosity under pain and the 2nd~3 caput metatarsale is caused to cause pain.Progression of the disease Predominantly following 4 stages：1. the intoe reversible stage：Halluces turns up 10 degree or so, influences beauty, without feeling of pain, foot The palm has slight foot cocoon, not will have a direct impact on walking, pain can be caused by wearing high heels.2. the intoe contracture stage：Halluces turns up 10-20 degree, joint and it is tough carry inflammation, the first the second toes of obviously squeeze, and sole obviously broadens, and vola foot cocoon is apparent, when long Between walking easily cause halluces arthralgia and sole pain.3. intoe severe stage：Halluces turns up 20-40 degree, toe Overlapping, crossbows collapses, corn, foot pad, flat foot followed by pain, and double-legged stress has much difficulty in healing weighing apparatus, seriously affects standing and walking.4. The halluces deformity stage：Halluces turns up 40 degree or more, and toe mission terminates, and big toe overlapping, toe does not stress, and arch of foot collapses It falls into, it is difficult to walk, sole directly bears toe portion pressure, and there is callus in vola, and biped serious error negative force, each joint is difficult to assist Allocation and transportation are made, and cause human body negative force line to change, gonitis is caused to be ached all over.

The therapy of intoe mainly has two kinds of operation and corrective therapy, and it is severe, lopsided that operative treatment is suitable for pain Serious patient.Operation mainly cuts off the sclerotin of synovial bursa, hyperplasia.It, can be with if the capsular ligament on the inside of articulationes metatarsophalangeae is excessively loose Make its deflation by overlapping suture partial joint capsule.Adductor pollicis tenotomy and first metatarsal bone osteotomy are also common side Method；Correction refers to then wear corrective instrument, and current pollex valgus correction appliance is worn on foot, and the bullet of part on instrument is passed through Property power reach correction purpose, but since the daily stress of human foot is very big, cause the external force that intoe is fallen ill also very big, example As some high-heeled shoes cause intoe fall ill be all body weight concentrate on forefoot and for a long time wear shoes move cause , but current rectifier has no idea to provide so big corrective force, is also unfavorable for patient and is moved in correcting process, and And current orthotics can not bear pain caused by its foot that persistently ties tight using so big corrective force patient.

The basis of shoes is made of sole and vamp, generally using the face of sole contact as interface, is referred to as sole with lower part, Heel is attached on sole, is a part for sole, and sole can be made by multilayer material；More than interface it is referred to as shoes Face, vamp can be spliced by polylith face, also had a small number of vamp area very littles to appear to be line and do not constituted face, but are also one Vamp is planted, the attachmentes such as shoestring can be equipped on vamp.

Invention content

To solve the above-mentioned problems, the present invention proposes a kind of shoes that can easily prevent and correct intoe.

In order to achieve the goal above, the technical solution adopted in the present invention is.

Intoe corrective shoes, are made of sole and vamp, are opened on vamp there are one gap, which makes on the inside of vamp only The part vamp of only remaining vamp rear is connect with vamp other parts, will using the most narrow place in the coupling part of rear as line of demarcation Vamp is defined as inside two regions of vamp and outside vamp, and outside vamp is equipped with the gap between thumb and forefinger The extension muscle position that position passes through, the muscle position are connect with sole, and inside vamp, which includes at least, is located at thumb phalanx and metatarsal joints Inside and area are more than 4 square centimeters of the face that can be contacted with foot.The feature description of above-mentioned construction can be explained further for, It is outside that the left side of right crus of diaphragm, which is on the right side of inside, and it is outside that the right side of left foot, which is on the left of inside, and vamp is connected by gap and inside and outside vamp Most narrow punishment is connect into two regions, the definition of inside is inside vamp, and lateral area is defined as outside vamp, and both sides vamp can be with It is different big, above-mentioned gap allow vamp front inside and outside between two parts change in the regime of elastic deformation of vamp material It is a part for vamp away from the muscle position that, the gap between thumb and forefinger passes through and is connected in sole, more precisely Say be lateral shoe extend downwardly forward the parting gap between thumb and forefinger pass through and in sole connect.Its principle is, Using on foot when sole be bent, jam on sole bending, due to being all fixed on sole inside and outside vamp, so the width of sole Constant, vamp upper is equipped with gap, inside vamp and outside vamp and narrows as sole flexural deformation has spacing to become nearly gap again Deformation, at this moment inside vamp is just to the Inside To Outside in the joint between thumb metatarsal and phalanx extruding foot, and outside Vamp is deformed inward and exactly inwardly squeezes foot on the outside of forefoot, while outside vamp extends to thumb and forefinger gap Between muscle bit position also with lateral shoe towards medial movement pressurize thumb outside, these three stress points of foot are exactly thumb Turn up correction when the correct point of application, while the corrective force that is converted of the immense pressure that foot bears when being utilized on foot also greater than The corrective force of most of orthotics, intermittence force are more favorable to the blood circulation of correction simultaneously.In order to preferably realize The one of effect of the lateral shoe towards the extension muscle position transmission power across thumb and forefinger, outside vamp or outside vamp Part hardness should be selected more larger elastic plastic material be it is most ideal, such as 60 degree of hardness PVC or TPU, but It is not excluded for that using soft cloth cover or leathering and on the whole addition the complex shoes of the supporting attachment of the transmission effect of power can be reached The way in face.The mechanics frame construction for the vamp that above-mentioned Instep structure for shoes description is refered in particular to, to additional to vamp mechanics on vamp Framework does not have influential attachment, does not influence its Instep structure for shoes and still conforms to Instep structure for shoes feature described in the invention.

It is additionally provided with hanging point on the vamp of above-mentioned intoe corrective shoes, and is equipped with hanging point connecting component, inside vamp is at least Equipped with 1 hanging point, outside vamp is connected with the hanging point of outside vamp with hanging point at least provided with 1 hanging point, the hanging point of inside vamp Component is connected.In order to further strengthen the effect of correction, and there is no foot to be made because of walking motion when such as standing or sitting posture At bending when can also have preferable corrective force and rectification effect, increase above-mentioned hanging point and hanging point connecting component, so-called hanging point The point of connecting component can be tangled by exactly referring to, can be salient point can also be hook or can be in the form of hole of impaling hook etc., can Can also be the increased attachment on vamp to be integrally formed, and link member can be simple flexible rubber ring, can also be Tether more can be poly-bag or tether that both ends carry the attachment that can be connected with hanging point, as long as can meet can connect two Hanging point just should comply with the description of this patent, in addition it can design multiple hanging points on inside vamp or outside vamp, be convenient for Different hanging points is connected by adjusting connecting component to finely tune pulling force.

The hanging point connecting component of above-mentioned intoe corrective shoes is elastomeric element.Elastomeric element is more favorably lasting with application Inside pulling force can also be the elastic force cushion rubber that can be adjusted the elastomeric element of pulling force, such as can adjust effective length, this company Relay part is not necessarily required to that homogenous material is integrally formed, such as can also be multiple as elastic force cushion rubber of the both sides with hook Close component.

The inside vamp of above-mentioned intoe corrective shoes or the hanging point on the vamp of outside are hanging point part, the hanging point part with Inside vamp or outside vamp are connected and fix.Hanging point, which can be an individual hanging point part, passes through the side for riveting or being bonded Formula is mounted on vamp basic material, can also be that several hanging points are integrated and this part is then passed through riveting on one part Or the methods of gluing is fixed on inside vamp or outside vamp.

Extension on the single part that the vamp of above-mentioned intoe corrective shoes is integrally formed, inside vamp or outside vamp Point is a protrusion on vamp material or groove or through-hole.This is the minimum way of cost, by mold by vamp material one The material with certain degree of hardness and toughness, such as the PVC or TPU of 60 degree of shore hardness are selected in secondary injection molding molding, and hanging point is only It is one on the vamp material special shape position that can tangle hanging point connecting component.

The above-mentioned horizontal cross-section of muscle position of intoe corrective shoes or so width is more than 3 millimeters, and anterior-posterior length is more than 16 millis Rice.In order to achieve the effect that correction, the muscle position should have certain support strength and the scale of construction, if the higher portion of selection hardness Comfort is realized and can be reduced to part, so the wider thicker shape of selection is more reasonable, and increases the contact surface with toe Product helps to reduce pressure when exerting a force, and reduces sense of discomfort.

Vamp and outside vamp phase connection on the inside of the vamp rear at the vamp gap rear of above-mentioned intoe corrective shoes Most narrow place is divided to be less than 20 millimeters.Support is played the role of in the part for being provided with the connection of the vamp after gap, is placed on vamp and is deformed inward When squeeze instep, the Regional contraction to that need not apply corrective force can operate unnecessary sense of discomfort, this inside vamp With outside vamp in the join domain of vamp rear can be integrally formed join domain can also be inside vamp and outside Vamp overlaps herein and fixed join domain, while meeting the requirement for supporting vamp rear in a word cannot it is too wide or It is too hard, cannot the front of inside vamp and outside vamp be deformed inward, 20 millimeters of the most narrow place of connection has been one very wide Supporting zone, can usually select 10 millimeters or so it is more reasonable.

The vamp of above-mentioned intoe corrective shoes is made of the plastic material 30 degree to 80 degree of shore hardness.In this hair Bright middle vamp is main mechanics frame construction, so above-mentioned vamp description should not include not influencing vamp mechanics framework Attachment, for example, the cloth of covering or Foot-rub-preventive cushion material etc., and vamp be exactly especially refer in particular to meet wearing and corrective force Mechanics framework select hardness suitably can again have with stress deformation to better meet the mechanics framework requirement of vamp It is more satisfactory selection that the plastic material of certain screen resilience, which is manufactured, especially can more be conducive to shape with mold integrated injection molding At more reasonably mechanics frame construction.

Above-mentioned intoe corrective shoes are a kind of dew flip-flop or peep-toe sandals.The demand of correction fully relies on shoes first half The structure divided is met, and the latter half of shoes is designed to that open slippers still more with the sandals of foot, have no effect on the correction of shoes Function, but basic structure will reveal toe.

There are one flexible accessories for above-mentioned intoe corrective shoes, are covered in except above-mentioned vamp, play sand prevention or warming Effect.The central inventive point of corrective shoes is that the power that preceding vamp upper partial cross-section is constituted transmits framework, although can usually set The structural form for counting into dew flip-flop and peep-toe sandals, it is also possible to increase cloth cover that is warming but not influencing mechanical structure, It can increase to not reveal the shoe style design of toe in waterproof or the cloth cover section material appearance of sand prevention.

Intoe corrective shoes proposed by the present invention are intended to make patient a kind of with intoe prevention and correcting function by wearing Mechanics vamp framework realize the prevention and correction of intoe, principle is stress deformation using shoes when on foot come to foot Apply corrective force again and again, is not the lasting sanguimotor corrective force that is unfavorable for, while people also being utilized to stand or walk Shi Tichong realizes the pressure of foot larger corrective force, has this stress carrier of shoes, corrective force need not be again from foot Some pressure spot is found to provide the fulcrum of power, and completely using shoes as the fulcrum of power, there will be no non-lesion for such foot Region an innocent person is brought disaster to, and additionally there are one it is important correcting the innovation of period, the solution of the present invention can be with sandals Or the form of slippers is implemented, and it can also be to add the outdoor shoe pattern formula in the form of sand prevention or warming cloth cover to implement, especially present invention choosing When implementation with the form of pantofle, a correction side for not needing patient's deliberately wear corrective device is virtually provided Case, but wear slippers indoors daily when all correcting or preventing intoe, this is very beneficial for continuing for corrective therapy Property and validity.
