Abstract
Description
Technical Field
[0001] The invention relates to a postoperative rehabilitation brace, in particular to a novel Achilles tendon boot structure with nonlinear heel pad adjustment. Background Art
[0002] After the Achilles tendon is ruptured or torn, if the medical imaging shows that the wound surface is small or the tear is small, conservative treatment can be used. However, during conservative treatment, the physiological phenomenon of scar tissue will fill the Achilles tendon rupture or tear area, replacing the toughness and elasticity of the ligament itself, causing the Achilles tendon to lose its original strength and toughness after overall recovery, and its functional effect is poor; if the fracture surface is large or the tear is large, it is best to use surgery. The surgical treatment of Achilles tendon rupture mainly includes open repair surgery and minimally invasive surgery. Among them, minimally invasive surgery has the characteristics of small injury surface, fast recovery, and good functional effect, and is widely used. However, during the recovery period after Achilles tendon surgery, the Achilles tendon cannot move normally and needs the assistance of Achilles tendon boots.
[0003] At present, there are many kinds of Achilles tendon boots on the market, for example: a lightweight Achilles tendon boot disclosed in Chinese patent CN109044585A, an Achilles tendon boot angle adjustment device disclosed in Chinese patent CN211049741U, a new Achilles tendon boot disclosed in Chinese patent CN213098608U, an Achilles tendon boot assembly for patients with Achilles tendon rupture disclosed in Chinese patent CN218391373U, an Achilles tendon boot with leveling function disclosed in Chinese patent CN116942390A, an Achilles tendon boot brace and a manufacturing method thereof disclosed in Chinese patent CN108354701A, etc. The structures and functions of these Achilles tendon boots can meet the needs of Achilles tendon postoperative rehabilitation. However, these Achilles tendon boots also have some disadvantages such as bulky structure, limited adjustment angle, cumbersome wearing and poor postoperative fixation effect, stuffy and airtight in summer, etc.
[0004] In order to solve the above problems, people have been seeking an ideal technical solution. Summary of the invention
[0005] The purpose of the present invention is to provide a novel Achilles tendon boot structure in view of the deficiencies in the prior art.
[0006] In order to achieve the above object, the technical solution adopted by the present invention is: A novel Achilles tendon boot structure with nonlinear heel pad adjustment comprises a separately arranged sole, a dorsal limiting structure and a heel pad, symmetrical side guards are arranged on both sides of the sole, and the sides of the two side guards close to the Achilles tendon are connected by an Achilles tendon protection structure; the heel pad comprises a hard connection structure and a flexible supporting structure, and the hard connection structure is detachably connected to the Achilles tendon protection structure; the two side guards are connected by a flexible connector.
[0007] The sole includes a front sole and a rear sole, the bottom surfaces of the front sole and the rear sole are integrally formed, the upper surface of the front sole is higher than the upper surface of the rear sole to form a step structure, and the upper surface of the front sole is an arc surface that is adapted to the shape of the first to fifth metatarsal bones of the human body.
[0008] The instep limiting structure is a instep limiting plate adapted to the instep, and the rear end of the instep limiting plate is bent and extended upward to be aligned with the upper end of the Achilles tendon protection structure.
[0009] The Achilles tendon protection structure is a rear foot protection plate adapted to the Achilles tendon portion of the heel, with a smooth transition between the rear foot protection plate and the side protection plates, and the upper side of the rear foot protection plate bulges upward in a dovetail shape.
[0010] A plurality of buckles are respectively arranged on the side guard plates, and the buckles on the two side guard plates are connected by a flexible connecting piece, and a Velcro assembly is arranged on the flexible connecting piece.
[0011] A number of heat dissipation holes are evenly arranged on the side guard plate and the instep limit plate.
[0012] A plurality of slots are evenly arranged on the inner side of the rear foot protection plate from top to bottom, and a card connecting piece is arranged on the hard connection structure corresponding to the slot, and the card connecting piece is connected to a certain slot; when the card connecting piece is connected to the uppermost slot, the angle between the flexible support structure and the sole is 40°, and when the card connecting piece is connected to the lowermost slot, the angle between the flexible support structure and the sole is 0°.
[0013] The hardness of the flexible support structure is Shore 40-50 A.
[0014] Compared with the prior art, the present invention has outstanding substantive features and significant progress. Specifically, the present invention provides a new Achilles tendon boot structure, which is mainly used for people who are recovering from severe Achilles tendon injuries after surgery. After the Achilles tendon is injured, especially after surgery, the Achilles tendon needs to be fixed in a position of 30 to 40 degrees of dorsiflexion for 1-2 weeks. After the fixation is removed, patients can often carry out simple daily life and walk with crutches wearing Achilles tendon boots. The next 2-6 months require targeted rehabilitation training for patients to gradually adapt the injured Achilles tendon to the stretched state. Compared with the Achilles tendon boot structure in the prior art, the heel pad in the present invention has a stronger adaptability, and the patient's use of the force on the hindfoot is uniform, and the body comfort is higher.
[0015] The present invention can achieve postoperative fixation, early rehabilitation training of the front part of the toes, angle adjustment of the rear end of the shoe, gait training, etc. through the design of the front end and rear end structures of the Achilles tendon boot, which is beneficial to dorsiflexion and plantar flexion training of the foot, improves the recovery of the overall function of the foot, and promotes the rapid recovery of the Achilles tendon function.
[0016] The length of each person's Achilles tendon is different, so the fixing angle of the Achilles tendon surgery is also different. The present invention can adjust the heel pad as needed, and the Achilles tendon adjustment angle range is 0 to 40 degrees, which increases the range of the adjustment angle.
[0017] On the basis of ensuring the functions of protection, adjustment, support, etc., the weight of the overall structure of the present invention is reduced to 40% of the original weight, which greatly improves the comfort of the user, reduces the burden of long-term weight-bearing on the injured leg, and improves the satisfaction of the Achilles tendon boot users.

DETAILED DESCRIPTION
[0027] The technical solution of the present invention is further described in detail below through specific implementation methods.
[0028] like Figure 1-8As shown, a novel Achilles tendon boot structure with nonlinear heel pad adjustment includes a separately arranged sole, an instep limiting structure S1 and a heel pad S11. Both sides of the sole are provided with symmetrical side guards S3. The sides of the two side guards S3 close to the Achilles tendon are connected by an Achilles tendon protection structure S5. The heel pad S11 includes a hard connection structure S12 and a flexible support structure. The hard connection structure S12 is detachably connected to the Achilles tendon protection structure S5. The two side guards S3 are connected by a flexible connector. Referring to the attached figure, the side guards are L-shaped as a whole, extending from both sides of the sole to both sides of the calf.
[0029] In one embodiment, the sole includes a front sole and a rear sole, and the bottom surfaces S9 (S8) of the front sole and the rear sole are integrally formed, and the upper surface S7 of the front sole is higher than the upper surface S6 of the rear sole to form a step structure, and the upper surface S7 of the front sole is an arc surface, which is adapted to the shape of the first to fifth metatarsal bones of the human body. The front sole is made of polymer rubber material, which has a greater effect on elasticity and bending degree, and is beneficial to the force when the forefoot is on tiptoe. In order to facilitate production, the front sole can adopt a double-layer structure, and the double layers are bonded together so as to form a step higher than the rear sole. In addition, the step structure can clamp the front end of the heel pad to limit the movement of the heel pad. Preferably, the structure on the front side of the heel pad is a wedge-shaped structure, which can adapt well to the sole of the foot and fit well with the sole of the foot to avoid the user's foot from being hurt when wearing it.
[0030] In one embodiment, the instep limit structure S1 is a instep limit plate adapted to the instep, and the rear end of the instep limit plate is bent upward and extended to align with the upper end of the Achilles tendon protection structure S5. The instep limit plate can be made of acrylonitrile-butadiene-styrene copolymer material with a certain hardness and elasticity, and the thickness is about 1.5-2mm.
[0031] In one embodiment, the Achilles tendon protection structure S5 is a rear foot protection plate adapted to the Achilles tendon of the heel, with a smooth transition between the rear foot protection plate and the side protection plate S3, and the upper side of the rear foot protection plate bulges upward in a dovetail shape. This "dovetail" structural bulge can well protect the Achilles tendon position, reduce weight and facilitate wearing.
[0032] In one of the embodiments, a plurality of buckles S4 are respectively provided on the side guard plates S3, and the buckles S4 on the two side guard plates S3 are connected by a flexible connector, and a Velcro assembly is provided on the flexible connector. Specifically, the flexible connector can be a flexible belt, which passes through the buckle to connect the two side guard plates, wraps the inner and outer ankles, and plays a strong supporting role on both sides, so that the overall structure of the Achilles tendon boot is relatively strong and stable. Combined with the instep limiting structure S1, the entire injured foot S10 is firmly fixed in the Achilles tendon boot of the present invention. Referring to the accompanying drawings, at least two groups of buckles are provided, one group is close to the forefoot sole, and the other group is close to the upper side of the ankle.
[0033] In one of the embodiments, a plurality of heat dissipation holes S2 are evenly arranged on the side guard plate S3 and the instep limit plate to enhance heat dissipation while reducing weight. When used in winter, a cotton lining can be added to increase warmth retention.
[0034] In one embodiment, a plurality of slots S14 are evenly arranged on the inner side of the rear foot protection plate from top to bottom, and a clamping piece S13 is arranged on the hard connection structure S12 corresponding to the slots S14, and the clamping piece S13 is connected to a certain slot S14; when the clamping piece S13 is connected to the uppermost slot S14, the angle between the flexible support structure and the sole is 40°, and when the clamping piece S13 is connected to the lowermost slot S14, the angle between the flexible support structure and the sole is 0°. Specifically, the clamping piece and the slot can be fan-shaped.
[0035] After Achilles tendon surgery or severe injury, the Achilles tendon or heel cannot bear weight. Figure 4 In order to promote the growth and recovery of the Achilles tendon after surgery or injury, the hindfoot lifting angle is between 30-40°. However, in order for the Achilles tendon to slowly return to its previous load-bearing state, the height of the hindfoot off the ground needs to be slowly changed to achieve the normal stretching state of the Achilles tendon.
[0036] In one of the embodiments, the hardness of the flexible support structure is Shore 40-50 A, which can provide certain support for the sole of the foot. The Achilles tendon boot provided in this embodiment is suitable for patients after Achilles tendon surgery or severe injury. First, the injured foot S10 is worn in the main structure of the Achilles tendon boot, and then the instep limiting structure S1 is placed above the instep, and the instep and side guard plates S3 are fixed by a flexible belt connected with Velcro. The foot plays a supporting and fixing role in the overall Achilles tendon boot. In addition, as the Achilles tendon recovers, it is necessary to lower the height of the heel pad in the Achilles tendon boot, and then adjust the connection height of the clip S13 of the heel pad. As the Achilles tendon recovers, the heel pad is finally smoothly placed in the Achilles tendon boot and fits completely with the sole. At this time, the front end of the heel pad is flush with the upper surface of the forefoot sole, which conforms to the stress state in the normal foot and the normal structure in the shoe, and improves the comfort of the user.
[0037] The above embodiments can be combined with each other.
[0038] The present invention provides a novel Achilles tendon boot structure with nonlinear heel pad adjustment, which is mainly used for people who are recovering after surgery for severe Achilles tendon injuries. After an Achilles tendon injury, especially after surgery, the Achilles tendon needs to be fixed in a position of 30 to 40 degrees of dorsiflexion for 1-2 weeks. After the fixation is removed, the patient can often carry out simple daily life and walk with crutches wearing the Achilles tendon boot. Referring to the walking posture A1 after the Achilles tendon injury in the attached figure, the patient needs to walk on tiptoe, with the back of the foot forming a certain angle with the ground A2. The patient will need targeted rehabilitation training for the next 2-6 months to allow the injured Achilles tendon to gradually adapt to the stretched state. Compared with the Achilles tendon boot structure in the prior art, the heel pad in the present invention has a stronger adaptability, and the patient's use of the boot results in a uniform force on the back foot, and a higher sense of comfort.
[0039] The present invention can achieve postoperative fixation, early rehabilitation training of the front part of the toes, angle adjustment of the rear end of the shoe, gait training, etc. through the design of the front end and rear end structures of the Achilles tendon boot, which is beneficial to dorsiflexion and plantar flexion training of the foot, improves the recovery of the overall function of the foot, and promotes the rapid recovery of the Achilles tendon function.
[0040] The length of each person's Achilles tendon is different, so the fixing angle of the Achilles tendon surgery is also different. The present invention can adjust the heel pad as needed, and the Achilles tendon adjustment angle range is 0 to 40 degrees, which increases the range of the adjustment angle.
[0041] On the basis of ensuring the functions of protection, adjustment, support, etc., the weight of the overall structure of the present invention is reduced to 40% of the original weight, which greatly improves the comfort of the user, reduces the burden of long-term weight-bearing on the injured leg, and improves the satisfaction of the Achilles tendon boot users.
[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention, which should be included in the scope of the technical solution for protection of the present invention.
