Technical Field

[0001] This utility model relates to the field of medical auxiliary products technology, and in particular to a chest wall fixation plate with preoperative positioning function for rib fracture surgery. Background Technology

[0002] With the rapid development of science and technology, humanity's pursuit of higher medical standards is increasing. In the medical field, there is a more urgent need to accelerate patient recovery and reduce patient suffering during surgery. Especially in the treatment of multiple rib fractures, how to effectively alleviate patient pain and improve treatment outcomes has become an important topic of medical research.

[0003] In the treatment of multiple rib fractures, it is usually necessary to first immobilize the affected area to reduce pain caused by breathing. This step is crucial for the smooth progress of the surgery. However, the commonly used aluminum plate fixation method has certain limitations. The shape of the aluminum plate restricts its close fit to the patient's body, resulting in limited fixation effectiveness. In addition, before surgery, the doctor needs to accurately locate the affected area to minimize the surgical incision. While surface positioning patches, which are widely used clinically, have achieved some success in accurately locating lesions within the body, their methods are relatively simple and can only provide a rough location. This undoubtedly affects the doctor's subsequent location of the affected area, thus impacting the determination of the surgical site.

[0004] Meanwhile, the fixation and positioning of the affected area are quite complex procedures, placing a significant workload on medical staff. During this process, patients may also experience unnecessary pain and even face the risk of secondary injury. These issues urgently need to be addressed to improve the treatment outcomes for multiple rib fractures.

[0005] To address these issues, the medical community has been actively exploring new treatment methods. For example, new materials can be developed to allow for a closer fit between the fixation device and the patient's body, improving fixation effectiveness. Simultaneously, advanced imaging technology can be combined to precisely locate the affected area, providing more accurate data support for surgery. Furthermore, optimizing surgical procedures can reduce surgical time and patient discomfort.

[0006] In conclusion, with advancements in technology, breakthroughs will continue to be made in the treatment of multiple rib fractures. In future medical practice, we look forward to providing patients with more comfortable, safe, and effective treatment options, allowing them to suffer less pain and recover their health as quickly as possible.

Detailed Implementation

[0031] Example 1

[0032] This invention provides a universal chest wall fixation plate, particularly suitable for preoperative positioning before rib fracture surgery. This fixation plate integrates positioning, fixation, and protection, and can adapt to different patient body structures and specific rib fracture conditions.

[0033] Main components:

[0034] 1. Positioning Plate Body: This is the core component of the fixing plate, made of shape memory material, which has excellent flexibility and malleability. The positioning plate body adopts a metamaterial structural design to reduce weight and improve breathability.

[0035] 2. Positioning Structure: The positioning structure is a key functional component of the fixation plate. It connects to the plate body to ensure precise positioning before surgery. The outer side of the positioning structure is covered with a protective film to protect the patient's skin from direct contact and damage.

[0036] 3. Fixing Buckles and Bandages: Fixing buckles are located on both sides of the positioning plate body. These buckles secure the positioning plate body and the positioning structure together, and bandages are fixed to the upper side of the buckles. The bandages consist of a male and a female Velcro side for easy and quick adjustment and fixation.

[0037] 4. Positioning Membrane: The positioning membrane is made of 3M material and has positioning markers and multiple manual positioning holes on its upper side. Adjacent positioning holes are marked with positioning markers to facilitate precise preoperative positioning by medical personnel. The positioning markers can be letters or Arabic numerals.

[0038] 5. Metal wires and metal powder: 1-3μm metal wires and metal powder are also provided on the positioning film. These metal wires intersect to form manual positioning holes, which enhances the stability and operability of the positioning structure.

[0039] 6. Positioning strip: The positioning strip is sprayed on the positioning plate body and serves as an auxiliary part of the positioning structure to further ensure the accuracy of positioning and the fixing effect.

[0040] 7. Adhesive layer: An adhesive layer is provided on one side of the skin layer to facilitate close contact between the fixation plate and the patient's skin while maintaining good breathability.

[0041] The positioning plate body consists of a shape memory plate crossbeam and a shape memory plate connecting piece. After these components are fixed together, they can restore the preset shape after heating, thereby achieving a personalized fixing effect.

[0042] The metamaterial structure of the positioning plate and the placement of the positioning membrane significantly improve the product's breathability and reduce patient discomfort.

[0043] The Velcro design makes the fixation plate easy to adjust and secure, allowing medical staff to quickly complete preoperative positioning.

[0044] This invention, through its innovative design and structure, provides an efficient, safe, and comfortable method for preoperative localization before rib fracture surgery, and is expected to be widely used in the medical field.

[0045] Example 2

[0046] When the positioning plate body is composed of shape memory plate crossbeams and shape memory plate connecting pieces, or when the positioning plate body is a metamaterial structure:

[0047] When the affected area is fixed

[0048] Before use, first immerse the positioning plate body in hot water at 50-60℃. The positioning plate body will completely soften in about 10 seconds. After removing the positioning plate body from the hot water for approximately 30 seconds, it will cool and become plastic. Therefore, immediately wrap the still-molded positioning plate body around the patient's affected area, ensuring it fits tightly to the patient's limb. After the fixing plate body has completely cooled, a completely body-fitting fixing structure is achieved. Then, the positioning plate body is installed on the bandage using the bandage clips. Finally, the overall structure is fixed to the body using the male and female sides of the Velcro on the bandage.

[0049] During preoperative lesion localization, CT scans are used to determine the precise location of the lesion. The CT scan first uses imaging technology to perform three-dimensional reconstruction of the patient's body fat and bones. Then, the operator adjusts the CT scanner window and display options to show the patient's bones in the three-dimensional view. The operator marks the bone damage area on the screen using the scanner. After marking, the operator changes the view to the patient's fat option, and the CT scanner screen displays the patient's current fat. Because the 3M membrane absorbs and blocks X-rays, artifacts are simultaneously displayed on the CT scanner screen. Medical staff determine and record the patient's wound based on the positioning marks displayed on the CT scanner screen. Then, based on the positioning marks displayed on the CT scanner screen, they mark the hollowed-out positioning marks on the patient's skin at the wound location. During surgery, after confirming accurate positioning, an incision is made directly at the marked location for minimally invasive surgery. This reduces the workload of medical staff and effectively reduces the patient's pain.

[0050] Example 3

[0051] When the positioning plate structure is a non-perforated structure and the positioning structure is located inside the positioning plate structure, the affected area is fixed;

[0052] Before use, first immerse the positioning plate body in hot water at 50-60℃. The positioning plate body will completely soften in about 10 seconds. After removing the positioning plate body from the hot water for approximately 30 seconds, it will cool and become plastic. Therefore, immediately wrap the positioning plate body, which is not yet fully plasticized after being heated in the water, around the patient's affected area, ensuring it fits tightly to the patient's limb. After the fixing plate body has completely cooled, a completely body-fitting fixing structure is achieved. Then, the positioning plate body is installed on the bandage using the bandage clips. Finally, the overall structure is fixed to the body using the male and female sides of the Velcro on the bandage.

[0053] Before surgery, CT scans are used to locate the lesion, further pinpointing its precise location. The CT scan first uses imaging technology to create a three-dimensional reconstruction of the patient's body fat and bones. The operator then adjusts the CT scanner's window frame and display options to show the patient's bones in the 3D view. The operator marks the bone damage area on the screen using the scanner. After marking, the operator changes the view to the patient's fat option, displaying the current fat area on the CT screen. Because the 3M membrane absorbs and blocks X-rays, artifacts appear on the CT screen. Medical staff use the positioning markers displayed on the CT screen to locate and record the wound. During surgery, the positioning plate and its clips are first opened, and the positioning plate is removed. The positioning structure is still attached to the affected area. The positioning markers are then located and marked in the nearby cutouts. After confirming accurate positioning, the medical staff makes an incision at the marked location for minimally invasive surgery. This reduces the workload of medical staff and effectively minimizes patient pain.

[0054] Example 4

[0055] When using an adhesive layer for fixation, before use, without removing the protective layer, immerse the positioning plate body in hot water at 50-60°C. The positioning plate body will completely soften in approximately 10 seconds. After removing the positioning plate body from the hot water for about 30 seconds, it will cool and become plastic. Therefore, after removing the positioning plate body from the water, remove the protective layer and immediately wrap the still-molded positioning plate body around the patient's affected area, ensuring it fits tightly to the patient's limb. After the fixation plate body has completely cooled, a fixation structure that perfectly conforms to the human body will be obtained.

[0056] During preoperative lesion localization, CT scans are used to determine the precise location of the lesion. The CT scan first uses imaging technology to perform three-dimensional reconstruction of the patient's body fat and bones. Then, the operator adjusts the CT scanner window and display options to show the patient's bones in the three-dimensional view. The operator marks the bone damage area on the screen using the scanner. After marking, the operator changes the view to the patient's fat option, and the CT scanner screen displays the patient's current fat. Because the 3M membrane absorbs and blocks X-rays, artifacts are simultaneously displayed on the CT scanner screen. Medical staff determine and record the patient's wound based on the positioning marks displayed on the CT scanner screen. Then, based on the positioning marks displayed on the CT scanner screen, they mark the hollowed-out positioning marks on the patient's skin at the wound location. During surgery, after confirming accurate positioning, an incision is made directly at the marked location for minimally invasive surgery. This reduces the workload of medical staff and effectively reduces the patient's pain.

[0057] Example 5

[0058] When the positioning plate body and positioning structure of this utility model are integrated into one structure, and the positioning plate body and positioning structure are made of metamaterial, the density of which is greater than that of human skin.

[0059] When using, without removing the protective layer, immerse the positioning plate body in hot water at 50-60℃. After approximately 10 seconds, the positioning plate body will completely soften. Remove the protective layer inside the skin layer and immediately wrap the not-yet-fully-shaped positioning plate body around the patient's affected area, ensuring it fits snugly against the patient's limb. After the fixing plate body has completely cooled, a completely body-fitting fixation structure will be achieved.

[0060] During preoperative lesion localization, CT scans are used to determine the precise location of the lesion. The CT scan first uses imaging technology to perform three-dimensional reconstruction of the patient's body fat and bones. Then, the operator changes the CT scanner window and display options to show the patient's bones in the three-dimensional view. The operator marks the bone damage area on the screen using the scanning device. After marking, the operator changes the view to the patient's fat option, and the CT scanner screen displays the patient's current fat. Because the positioning plate and positioning structure are made of metamaterial with a density greater than human skin, the skin and the device present different shadows during CT use, creating artifacts on the CT scanner screen. Medical staff determine and record the patient's wound based on the positioning marks displayed on the CT scanner screen. Then, based on the positioning marks displayed on the CT scanner screen, they mark the hollowed-out positioning marks on the device at the wound location on the patient's skin. During surgery, after confirming accurate positioning, an incision is made directly at the marked location for minimally invasive surgery. This reduces the workload of medical staff and effectively reduces the patient's pain.
