no. 1 example

[0034] like figure 1 As shown, a 3D printed T-shaped shoe is provided, comprising an instep fixing part 1, a sole support part 2 and an ankle fixing part 3, wherein the instep fixing part is made of 3D printing, and includes an inner layer 4 conforming to the patient's foot surface And wrap the skeleton layer 5 fixed on the outside of the inner layer. Among them, the skeleton layer is a soft plastic layer, such as latex, which has a setting effect and is deformed under the action of external force, but after the external force is removed, it can be restored to its original state, so that it can wrap and fix the instep of the patient, but it will not affect the skin. cause discomfort, with better comfort. At the same time, the inner layer of this embodiment is a silica gel layer, and the silica gel has good affinity, which can form better protection for the skin, and there will be no skin problems.

[0035] When making the instep fixing part, first perform a three-dimensional...

no. 2 example

[0041] Different from the first embodiment, the sole support part of this embodiment is also 3D printed, and the sole support part is set as a double-layer structure including a support layer 10 and a bonding layer 11, such as image 3As shown in the figure, the support layer is made of flexible deformable material, so that it has a certain deformation ability and can be bent to a certain extent, so that the patient's sole can be rotated back and forth at a certain angle at the heel to perform certain activities and promote Blood circulation, prevent joint stiffness, muscle atrophy, lower extremity venous thrombosis and other complications. At the same time, the fit layer can also improve the fit with the sole of the foot and improve comfort

[0042] In this embodiment, the support layer is a soft plastic layer, such as latex, cooked glue, etc., and the adhesive layer is a silicone layer.

no. 3 example

[0044] Different from the second embodiment, the ankle fixing part of the present invention is printed, so that the T-shaped shoe can be printed in one piece, which can significantly improve the production efficiency.

[0045] In all the above solutions, the instep fixing portion and the sole support portion are both porous structures 12 . like figure 1 , 2 , 3, the gas in the shoe can be exchanged with the outside, thereby alleviating the formation of a closed environment in the shoe and reducing the occurrence of various skin complications.

Abstract

The invention relates to a 3D printed T-shaped shoe, and belongs to the technical field of medical supplies, the 3D printed T-shaped shoe comprises an instep fixing part adopting 3D printing, and the instep fixing part comprises an inner layer matched with the instep of a patient in shape and a skeleton layer fixed outside the inner layer in a wrapping mode. According to the T-shaped shoe, the instep fixing part is customized in a personalized mode through 3D printing, so that the T-shaped shoe is matched with the outline of the instep of a patient in shape, the instep is well wrapped, the good fixing effect can be achieved without the high fixing force of a fastening belt, and therefore the comfort degree is improved. Meanwhile, the double-layer structure of the inner layer and the framework layer is adopted, on one hand, the instep fixing part has certain fixing strength, the firm fixing state of the instep is kept, and falling is effectively prevented, and on the other hand, through wrapping and attaching of the inner layer and the instep, the attaching level of the instep fixing part and the instep is improved, and comfort is further improved.

Description

technical field [0001] The invention relates to the technical field of medical care products, in particular to a 3D printed T-shaped shoe that can conform to human feet. Background technique [0002] Proximal femoral fracture, femoral shaft fracture or combined common peroneal nerve injury, artificial femoral head replacement, hemiplegia caused by cerebrovascular disease need to wear T-shaped shoes to keep the affected limb in a neutral position to prevent foot drop, foot internal rotation, Foot external rotation, prosthesis dislocation, malunion and other complications, so T-shaped shoes play an important role in the rehabilitation of patients' lower extremities. [0003] In order to facilitate the insertion of the existing T-shaped shoes, the toe opening structure is usually adopted, the upper is made of soft cotton cloth, and the upper part of the cotton cloth on the left and right sides is provided with a tightening belt. Since the cotton cloth has no stable wrapping abi...
