Description

Technical Field

[0001] The utility model relates to the technical field of medical care appliances, in particular to a 3D printed brace for treating lingual calcaneal fractures and preventing soft tissue damage. Background Art

[0002] Tongue-type calcaneal fractures account for 14%-20% of all calcaneal fractures. They can occur as isolated fracture lines or as part of a more complex intra-articular calcaneal fracture pattern. After completing the tongue-type calcaneal fracture reduction surgery, the foot and ankle need to be fixed with plaster to prevent the affected area from being stressed. However, the current plaster fixation method causes the plaster to contact the upper part of the heel where the nails are implanted in the tongue-type calcaneal fracture reduction surgery, making it impossible for patients to apply medication regularly, which can cause soft tissue necrosis. Although simply opening a window on the plaster surface allows the upper part of the heel to be medicated normally, the patient will unconsciously let the upper part of the heel contact other sources of contamination such as bedding when sleeping, which can cause infection and affect the patient's recovery.

[0003] At present, the utility model with patent number CN214805929U discloses a timed cold therapy device for ankle fracture and plaster fixation, comprising a cold therapy sleeve, a circular hole is opened in the middle of the cold therapy sleeve, and the patient's heel passes through the hole. The cold therapy sleeve comprises a heat preservation sleeve and a cold therapy water bag arranged in sequence from the outside to the inside, and the heat preservation sleeve and the cold therapy water bag cover the instep and both ankles, and the cold therapy water bag is placed inside the heat preservation sleeve; the upper end of the cold therapy sleeve, located on the left and right sides of the human calf, is respectively provided with buttons, one end of the connecting belt is opened with a twist hole and is sleeved on the above-mentioned buttons, and the other end of the connecting belt is fixed on the fastening ring, and the two ends of the fastening ring are fixed by Velcro and adhesive tape; the cold therapy sleeve is located above the instep and can be unfolded, and is fixed by a zipper or Velcro, adhesive tape; the surface of the cold therapy sleeve is provided with a pocket, and a timer is arranged inside the pocket. The utility model relates to a timed cold therapy device for ankle fracture and plaster fixation, which has better fitting and cold compress effects and ensures the cold compress time. However, this application plan cannot protect the incision, and cannot ensure that the upper part of the heel will not be contaminated by other pollution sources when the patient is unconscious, such as sleeping or distracted. Therefore, it is not very suitable for the follow-up treatment of calcaneal lingual fractures. Summary of the invention

[0004] In view of the problems existing in the above-mentioned prior art, the utility model provides a 3D printed brace for treating tongue-type calcaneal fractures and preventing soft tissue damage. The incision located on the upper part of the heel during tongue-type calcaneal fracture reduction surgery can be exposed so as not to affect the application of medication on the patient. The incision can be provided with sufficient protection to facilitate the patient's recovery.

[0005] In order to achieve the above-mentioned purpose, the utility model is a 3D printed brace for calcaneal lingual fracture and preventing soft tissue damage, comprising a calf plate, a heel window plate, a plantar plate, an opening, a bandage hole and a calf extension plate, wherein the rear end of the plantar plate is fixedly connected to the lower end of the heel window plate, the upper end of the heel window plate is fixedly connected to the lower end of the calf plate, and the surface of the calf plate is provided with an arc-shaped groove that fits the rear part of the calf; and bandage holes are opened in pairs near the edges on both sides of the calf plate and the plantar plate.

[0006] In addition, the 3D printed brace suitable for calcaneal lingual fracture proposed in the above embodiment of the utility model may also have the following additional technical features:

[0007] As a further improvement of the utility model, a rectangular groove is formed on the upper part of the calf plate, and the calf extension plate is inserted into the groove.

[0008] As a further improvement of the present invention, the calf extension plate is arc-shaped.

[0009] As a further improvement of the present invention, the bandage holes are waist-shaped holes, and the number is three to four pairs.

[0010] As a further improvement of the present invention, an opening is provided in the middle of the window plate.

[0011] Through the above scheme, the utility model has at least the following advantages: compared with conventional plaster fixation, by adding a support composed of a calf plate, a heel window plate and a plantar plate into the plaster, protection is provided for the patient's heel, the incision on the upper part of the heel during tongue-type calcaneal fracture reduction surgery can be exposed without affecting the patient's medication, and the incision can be provided with sufficient protection to facilitate the patient's recovery.
