Description

Technical Field

[0001] This utility model relates to the field of medical care equipment technology, and more specifically, to a 3D printed elbow joint fixation brace. Background Technology

[0002] In recent years, 3D printing technology has shown great potential in the medical field due to its advantages such as personalized customization, complex structure molding and rapid manufacturing. Through three-dimensional reconstruction of CT / MRI data, it can accurately match the anatomical shape of the patient's elbow joint and design a fixation brace with high fit and excellent mechanical performance. Compared with traditional standard braces, 3D printing technology can design differentiated constraint schemes for different injury types, and at the same time achieve a balance between breathability and support through hollow structure optimization.

[0003] After coronary intervention, patients are prone to rebleeding at the surgical site and hematoma around the surgical site due to the use of anticoagulants. Therefore, adequate compression of the brachial artery and elbow immobilization are the most important aspects of preventing complications. Currently, the commonly used method of elbow immobilization in clinical practice is still to use gauze to fix the puncture site of the elbow joint on the puncture side after the operation, and immobilization is achieved by simply restricting the movement of the puncture side limb.

[0004] However, during the immobilization period, patients need to eat, go to the toilet, or pick up objects. These actions can cause elbow joint movement, which may lead to rebleeding or hematoma. Moreover, this method is not comfortable for patients and cannot guarantee effective immobilization of the puncture site or prevent forearm rotation, thus leading to local vascular complications at the puncture site.

[0005] Therefore, a 3D-printed elbow joint fixation brace is proposed to address the above problems. Utility Model Content

[0006] 1. Technical problems to be solved

[0007] In view of the problems existing in the prior art, the purpose of this utility model is to provide a 3D printed elbow joint fixation brace that can prevent the patient's forearm from rotating and improve comfort.

[0008] 2. Technical Solution

[0009] To solve the above problems, the present invention adopts the following technical solution.

[0010] A 3D-printed elbow joint fixation brace includes two elastic bands, each with Velcro on its outer surface. A fixing component is fixedly connected to the inner surface of both elastic bands. Three connecting components are fixedly connected to the left side of the fixing component. Another fixing component is fixedly connected to the left side of the three connecting components. A protective component is slidably connected inside the two fixing components.

[0011] Furthermore, the fixing component includes a fixing arc plate, the inner surface of which has two strap holes, a plurality of ventilation holes of different shapes, and a plurality of slots.

[0012] Furthermore, the protective component includes a silicone pad with two strap holes on its outer surface and several ventilation holes of different shapes on its outer surface. Several silicone rods are fixedly connected to the outer surface of the silicone pad. The silicone rods cooperate with the slots to fix the silicone pad to the fixed arc plate, which can effectively improve the patient's comfort when fixing the patient's elbow joint.

[0013] Furthermore, the connecting assembly includes a connecting block, a connecting pipe is fixedly connected to the inner surface of the connecting block, a pin is slidably connected to the inner surface of the connecting pipe, and two connecting plates are slidably connected to the outer surface of the pin.

[0014] Furthermore, the positions of the two strap holes 2 correspond to the positions of the two strap holes 1, the positions of the several vent holes 2 correspond to the positions of the several vent holes 1, and the outer surfaces of the several silicone inserts are slidably connected to the inner surfaces of the several slots.

[0015] Furthermore, the right ends of the six connecting plates are fixedly connected to the left end of the fixed arc plate located on the left side, and the left ends of the three connecting blocks are fixedly connected to the right end of the fixed arc plate located on the right side.

[0016] 3. Beneficial effects

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] This solution utilizes 3D printing technology to customize fixation plates based on the patient's elbow joint anatomy, ensuring a close fit between the brace and the patient's elbow. The silicone inserts and slots work together to quickly fix the silicone pad onto the inner surface of the fixation plate, evenly distributing pressure and reducing localized pressure during elbow fixation. Irregular ventilation holes promote airflow, reducing the risk of skin stuffiness and pressure sores, significantly improving patient comfort. Furthermore, the open design of the two fixation plates allows for easy avoidance of puncture sites, effectively preventing pressure on these areas and enhancing the practicality of the fixation brace.

[0028] Example 1:

[0029] Please see Figure 1-4A 3D-printed elbow joint fixation brace includes two elastic bands 1, each with Velcro on its outer surface. The inner surfaces of the two elastic bands 1 are fixedly connected to a fixing component 2. The left side of the fixing component 2 is fixedly connected to three connecting components 4. The left side of the three connecting components 4 is fixedly connected to another fixing component 2. The two fixing components 2 are slidably connected to a protective component 3 inside each other.

[0030] This solution connects two fixation components 2 together using three connecting components 4. Two elastic bands 1 can simultaneously pull the two fixation components 2 inward to fix part of the upper arm and part of the forearm on both sides of the patient's elbow joint, preventing the patient's forearm from rotating and ensuring effective immobilization of the puncture site. By inserting protective components 3 into the two fixation components 2, the patient's comfort during fixation is improved.

[0031] Please see Figure 2-4 The fixing component 2 includes a fixing arc plate 21. The inner surface of the fixing arc plate 21 has two strap holes 22 and several ventilation holes 23 of different shapes. The inner surface of the strap holes 22 has several slots 24.

[0032] The protective component 3 includes a silicone pad 31. The outer surface of the silicone pad 31 has two strap holes 32, the positions of which correspond to the two strap holes 22. The outer surface of the silicone pad 31 has several ventilation holes 34 of different shapes, the positions of which correspond to several ventilation holes 23. Several silicone rods 33 are fixedly connected to the outer surface of the silicone pad 31, and the outer surfaces of the silicone rods 33 are slidably connected to the inner surfaces of several slots 24.

[0033] The connecting component 4 includes connecting blocks 41. The left ends of the three connecting blocks 41 are fixedly connected to the right end of the fixed arc plate 21 located on the right side. A connecting pipe 42 is fixedly connected to the inner surface of the connecting blocks 41. A pin 43 is slidably connected to the inner surface of the connecting pipe 42. Two connecting plates 44 are slidably connected to the outer surface of the pin 43. The right ends of the six connecting plates 44 are fixedly connected to the left end of the fixed arc plate 21 located on the left side.

[0034] In practical applications, three-dimensional reconstruction can be performed based on the patient's CT / MRI data. Two fixed arc plates 21 conforming to the patient's elbow shape can be fabricated using 3D printing technology. Then, pins 43 are used to pass through the center of the two connecting plates 44 and the connecting tube 42. Several silicone rods 33 and slots 24 are used to fix two silicone pads 31 to the inner surfaces of the two fixed arc plates 21. Finally, two elastic bands 1 are passed through the first strapping hole 22 of the fixed arc plate 21 and the second strapping hole 32 of the silicone pad 31, and then from the other fixed arc plate... The brace is then inserted through the strap hole 22 of plate 21, allowing it to be placed on the patient's elbow joint. This ensures that the space between the two elastic bands 1 is located at the puncture site. The elastic bands 1 are then tightened, and the brace is secured to the patient's elbow joint using Velcro. At this point, the two fixing arc plates 21 will fix part of the upper arm and part of the forearm on both sides of the patient's elbow joint to inhibit the rotation of the patient's forearm. Meanwhile, the openings of the two fixing arc plates 21 correspond to the patient's puncture site, preventing pressure on the puncture site and effectively immobilizing it.

[0035] During this process, the combination of several ventilation holes 23 and several ventilation holes 34 can effectively enhance breathability and reduce the risk of skin stuffiness and pressure sores; through the direct contact between the two silicone pads 31 and the patient's skin, the patient's wearing comfort is effectively improved.

[0036] Working principle:

[0037] Two fixed arc plates 21, conforming to the shape of the patient's elbow, are made using 3D printing technology. Then, a pin 43 is used to pass through the center of the two connecting plates 44 and the connecting tube 42 to connect the two fixed arc plates 21 together. Then, using the cooperation of several silicone rods 33 and several slots 24, two silicone pads 31 are fixed to the inner surfaces of the two fixed arc plates 21 respectively. Finally, two elastic bands 1 are passed through the first binding hole 22 of the fixed arc plate 21 and the second binding hole 32 on the silicone pad 31, and then pass out through the first binding hole 22 of the other fixed arc plate 21. At this point, the brace can be placed on the patient's elbow joint, so that the space between the two elastic bands 1 is located at the puncture site.

[0038] Tighten the elastic band 1 and fix the brace to the patient's elbow joint with the Velcro. At this time, the two fixing arc plates 21 will fix part of the upper arm and part of the forearm on both sides of the patient's elbow joint to inhibit the rotation of the patient's forearm. At the same time, the opening position of the two fixing arc plates 21 corresponds to the patient's puncture site, so it will not compress the puncture site and can effectively brake the puncture site.

[0039] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
