Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a foot drop and inversion restraint and fixation device. Background Technology

[0002] Ankle and foot braces are medical devices used to treat and prevent foot and ankle injuries, deformities, or functional impairments. They primarily promote rehabilitation by immobilizing, correcting, or restricting joint movement. Based on function, they can be divided into static braces and dynamic braces: Static braces use a one-piece design to completely restrict ankle joint movement and are used to correct deformities such as foot drop and inversion / eversion, but may lead to gait stiffness; dynamic braces use a split structure, allowing ankle dorsiflexion movement, and are suitable for hemiplegic patients or situations requiring the preservation of some mobility, offering superior comfort and rehabilitation effects.

[0003] Patients who have undergone hemiplegic surgery already have surgical wounds in their feet and ankles, resulting in slow blood flow. Wearing rigid braces is not comfortable, and prolonged use can easily cause pressure and damage to the patient's skin. Furthermore, for hemiplegic patients, due to long-term foot deformities leading to muscle contractures, ligament fibrosis, and neuromodulation failure, simply using rigid foot and ankle fixation devices to forcibly maintain the foot in an extended position after surgery may still cause foot drop recurrence due to biomechanical imbalance.

[0004] However, dynamic braces may cause various adverse consequences due to the inconvenience of disassembly, assembly, and adjustment. They may directly reduce the corrective effect, and the cumbersome disassembly and assembly will increase the risk of operational errors. Furthermore, the high maintenance cost of dynamic braces may cause patients to delay the treatment window due to difficulties in traveling back and forth, thereby increasing their economic burden. Utility Model Content

[0005] The purpose of this utility model is to provide a fixing device that is easy to adjust and can fully guarantee the fixing effect;

[0006] A foot drop and inversion restraint and fixation device is provided, including a foot fixation device, a knee fixation device and elastic bands. Elastic bands are respectively provided on both sides of the mid-foot position of the foot fixation device to connect to both sides of the knee fixation device.

[0007] As a preferred embodiment, the foot fixing device is provided with fixing straps at the midpoint of the forefoot and the midpoint of the heel.

[0008] As a preferred embodiment, the fixing strap is equipped with Velcro for adjustment and fixation.

[0009] As a preferred embodiment, the elastic band is equipped with a snap fastener for connecting to the knee fixation device.

[0010] As a preferred embodiment, the elastic band includes an upper elastic band, a lower elastic band, and a D-ring buckle, with one end of the upper and lower elastic bands inserted into the D-ring buckle for fixation.

[0011] As a preferred embodiment, an anti-slip block is provided at one end of the upper and lower elastic bands that are inserted into the D-ring buckle.

[0012] As a preferred embodiment, the foot fixation device is an elastic stocking or an elastic foot pad.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention utilizes the synergistic effect of flexible materials and an adjustable dynamic structure to maintain a neutral dorsiflexion position of the foot while preserving moderate ankle joint mobility. The foot fixation device uses elastic stockings or elastic insoles as the contact surface, combined with Velcro straps at the forefoot and heel to achieve even pressure distribution and avoid localized compression. The knee fixation device is connected to the foot via double-sided elastic bands, using D-rings to adjust the traction tension, creating a controllable dorsiflexion pull to prevent foot drop and inversion deformities. The ends of the elastic bands are quickly attached and detached via snap fasteners, and anti-slip blocks ensure stable traction direction, ensuring ease of wear and promoting the recovery of foot and ankle muscle function.

[0020] To illustrate the features of this utility model, the following description, in conjunction with the accompanying drawings and embodiments, will further explain this utility model.

[0021] Example:

[0022] Please see Figure 1 and Figure 2This utility model embodiment provides a foot drop and inversion restraint and fixation device. The foot fixation device 1 uses a foot pad (made of 80% high-elasticity nylon + 20% spandex blend). Two 3cm wide elastic bands 3 (made of latex core wrapped with high-elastic fiber) are set on both sides of the middle of the foot pad. The ends of the elastic bands 3 are connected to the knee fixation device 2 by snap fasteners. The knee fixation device 2 is an adjustable knee strap structure. The foot fixation device 1 adds two fixing straps 4 in the middle of the foot and the middle of the heel. The fixing straps 4 are 4cm wide Velcro straps to adapt to patients with different arch heights.

[0023] Preferably, in this embodiment, the elastic band 3 is divided into an upper elastic band 31 and a lower elastic band 32 (length adjustable range 25-40cm). Both are threaded into a D-ring buckle 33 to form a length adjustment system. By sliding the D-ring buckle 33, the effective length of the elastic band 3 can be changed, thereby adjusting the back extension traction force. An anti-detachment stop 34 is provided at the end of the elastic band 3 that enters the D-ring buckle 33 to prevent the upper elastic band 31 and the lower elastic band 32 from accidentally detaching during traction.

[0024] The usage method of this embodiment is as follows:

[0025] Use of the device:

[0026] The patient first puts on the knee fixation device 2, then puts on the foot fixation device 1, tightens the fixation strap 4 at the instep and fixes it to the instep; tightens the two fixation straps 4 at the heel and fixes them to the ankle; tightens the elastic band 3, and combines the snap fastener at one end of the elastic band 3 with the snap fastener at the knee fixation device 2, adjusts the sitting or lying position, and adjusts the length of the elastic band 3 through the D-ring buckle 33 to maintain the dorsiflexion neutral position of the foot at 90 degrees.

[0027] This embodiment utilizes the synergistic effect of flexible materials and an adjustable dynamic structure to maintain a neutral dorsiflexion position of the foot while preserving moderate ankle joint mobility. The foot fixation device uses an elastic insole as the contact surface, combined with Velcro straps at the forefoot and heel to achieve even pressure distribution and avoid localized compression. The knee fixation device is connected to the foot via double-sided elastic bands, using D-rings to adjust the traction tension, forming a controllable dorsiflexion traction force to prevent foot drop and inversion deformities. The ends of the elastic bands are quickly attached and detached via snap fasteners, and anti-slip blocks ensure stable traction direction, meeting the requirements of ease of wear and promoting the recovery of foot and ankle muscle function.
