Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to anatomical metal bone plates. Background Technology

[0002] Anatomical metal bone plates are medical devices used for fracture treatment. They are primarily made of metal and designed according to the anatomical morphology of bones in different parts of the human body. Their function is to surgically fix the plate to the fracture site after a fracture occurs. The plate's support and fixation function helps maintain a stable position of the fracture ends, creating favorable conditions for bone healing and promoting the gradual restoration of the fracture site to its normal physiological structure and function.

[0003] A search revealed publication number CN205626082U, which discloses an anatomical metal bone plate, comprising a bone plate body, pressure holes, side wing main plates, side wing locking holes, main plate locking holes, and a support plate. One end of the bone plate body is connected to the support plate. A pressure hole is provided on the side of the bone plate body connected to the support plate, and a main plate locking hole is provided on the other side of the bone plate body. The side wing main plates are connected to the upper side of the bone plate body, and the connection between the side wing main plates and the bone plate body is a rhomboid or square structure. Side wing locking holes are provided on the side wing main plates. In clinical use, the bone plate of this invention can be slightly adjusted according to individual differences, has a large fixation range, reduces the workload of physicians, and its high plasticity reduces the probability of bone plate fracture during the healing period.

[0004] The anatomical structure of bones is complex, and traditional calcaneal fracture fixation techniques cannot well adapt to different parts and types of fracture morphology of the calcaneus. Fixation devices cannot accurately fit the surface of the calcaneus, resulting in uneven stress distribution, affecting fracture healing, and even causing complications. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an anatomical metal bone plate, which aims to improve the problem that existing bone plates cannot accurately fit the surface of the root bone, thus affecting treatment.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an anatomical metal bone plate, comprising a first connecting plate, a first branch fixedly connected to the right side of the first connecting plate, a second branch fixedly connected to the right side of the first branch, a third branch fixedly connected to the top of the first connecting plate, a fourth branch fixedly connected to the left side of the first connecting plate, and a fifth branch fixedly connected to the bottom left side of the first connecting plate.

[0007] The above technical solution aims to maintain basic stability at the fracture site. This type of bone plate can provide patients with some psychological reassurance in the early postoperative period. Because its fixation effect is directly visible and the surgical trauma is relatively small, patients usually experience less postoperative pain and can more actively cooperate with early rehabilitation training, such as performing simple foot flexion and extension exercises in bed. This not only helps promote local blood circulation and prevent deep vein thrombosis in the lower extremities, but also lays a good foundation for further weight-bearing exercises.

[0008] As a further description of the above technical solution: Preferably, the first connecting plate has a circular hole on its surface, the first branch has circular holes around its perimeter, the second branch has a circular hole on its right side, the third branch has two circular holes at its top and bottom, the fourth branch has four circular holes on its surface, and the fifth branch has three circular holes on its surface. The angle between the third branch and the first branch is 125 degrees, the angle between the fourth branch and the third branch is 40 degrees, and the angle between the fifth branch and the fourth branch is 35 degrees. The first connecting plate, the first branch, the second branch, the third branch, the fourth branch, and the fifth branch are integrally formed and have an overall length of 88 mm.

[0009] Through the above technical solution, because this type of bone plate has high fixation accuracy, it reduces the occurrence of chronic pain or gait abnormalities caused by poor fixation, ensures good recovery of the patient's foot function, and enables them to return to normal life and work more quickly.

[0010] As a further description of the above technical solution: Preferably, it includes a second connecting plate, a first fixing plate is fixedly connected to the right side of the second connecting plate, a second fixing plate is fixedly connected to the left side of the second connecting plate, a third fixing plate is fixedly connected to the left side of the second fixing plate, a fourth fixing plate is fixedly connected to the bottom of the third fixing plate, and a fifth fixing plate is fixedly connected to the bottom left side of the second connecting plate.

[0011] The above technical solution is of great significance for the precise fixation of this type of bone plate in the treatment of fractures of the lateral wall of the calcaneus. On the one hand, stable fixation avoids secondary damage to the surrounding muscles, tendons and nerves caused by further displacement of the fracture fragments. On the other hand, by maintaining the normal anatomical shape of the calcaneus, it ensures the balance of force on the lateral soft tissues and reduces the risk of postoperative soft tissue adhesion and contracture.

[0012] As a further description of the above technical solution: Preferably, the second connecting plate has four round holes on its surface, the first fixing plate has round holes at its top and bottom, and the second fixing plate has round holes at its top and left side; the third fixing plate has round holes at its top and bottom, and the fourth fixing plate has a round hole at its bottom; the angle between the second fixing plate and the fourth fixing plate is 90 degrees, and the angle between the second fixing plate and the fifth fixing plate is 35 degrees; the second connecting plate, the first fixing plate, the second fixing plate, the third fixing plate, the fourth fixing plate, and the fifth fixing plate are integrally formed and have an overall length of 60 mm.

[0013] The above technical solutions enable patients to better preserve the range of motion of the lateral side of their foot during rehabilitation, maintain balance when walking and standing, reduce the risk of falls due to foot discomfort, improve self-care ability, and clearly show the good maintenance of width and height of the calcaneus during the healing process in imaging follow-up, providing strong evidence for the full recovery of joint function.

[0014] As a further description of the above technical solution: Preferably, the device includes a third connecting plate, a first connecting piece fixedly connected to the right side of the third connecting plate, a second connecting piece fixedly connected to the bottom left side of the third connecting plate, a third connecting piece fixedly connected to the left side of the second connecting piece, and a fourth connecting piece fixedly connected to the left side of the third connecting plate.

[0015] Through the above technical solution, for complex fractures involving the talocalcaneal joint surface, the comprehensive stabilization and fixation of this type of bone plate not only reduces the fracture fragments, but also greatly improves the stress environment of the articular cartilage after restoring the smoothness of the joint surface, so that the synovial fluid can be evenly distributed, providing sufficient nutrients for chondrocytes and effectively delaying the degenerative process of cartilage.

[0016] As a further description of the above technical solution: Preferably, the third connecting plate has round holes at its bottom and right side, the first connecting piece has round holes at its top and bottom, the third connecting piece has three round holes on its surface, the fourth connecting piece has three round holes on its surface, the angle between the first connecting piece and the second connecting piece is 145 degrees, the angle between the second connecting piece and the third connecting piece is 135 degrees, and the third connecting plate, the first connecting piece, the second connecting piece, the third connecting piece and the fourth connecting piece are integrally formed and have an overall length of 65 mm.

[0017] Through the above technical solutions, during postoperative rehabilitation training, when patients perform joint flexion, extension, inversion and eversion activities according to the principle of gradual progression, they can clearly feel the joint flexibility gradually improving and the pain gradually decreasing. At the same time, due to the reliable support of the bone plate on the joint surface, the joint surface can remain stable even in the initial partial weight-bearing stage, reducing the potential threat of traumatic arthritis and long-term complications, ensuring the long-term foot function of patients, and improving their quality of life.

[0018] As a further description of the above technical solution: Preferably, it includes a fourth connecting plate, a first support plate is fixedly connected to the top left side of the fourth connecting plate, a second support plate is fixedly connected to the bottom left side of the fourth connecting plate, a third support plate is fixedly connected to the top left side of the second support plate, a fourth support plate is fixedly connected between the first support plate and the third support plate, and a fifth support plate is fixedly connected between the first support plate and the second support plate.

[0019] Through the above technical solution, when used for fractures of specific parts of the anterior or posterior calcaneus, this model has the advantage of local stability of the bone plate. Taking the calcaneal tuberosity fracture as an example, after fixation, the anatomical position of the calcaneal tuberosity can be accurately restored, which is crucial for the attachment and force generation of the Achilles tendon.

[0020] As a further description of the above technical solution: Preferably, the fourth connecting plate has round holes at all four corners, the first support plate has two round holes, the second support plate has three round holes, the third support plate has two round holes, and the fourth support plate has one round hole. The angle between the first and second support plates is 45 degrees. The fourth connecting plate, the first support plate, the second support plate, the third support plate, the fourth support plate, and the fifth support plate are integrally formed and have an overall length of 65 mm.

[0021] Through the above technical solutions, when patients perform heel raises and jumping exercises during later rehabilitation training, the Achilles tendon can transmit force normally, avoiding Achilles tendon damage or force transmission disorders caused by abnormal position of the calcaneal tuberosity. For anterior calcaneal fractures, this type of bone plate ensures the normal structure of the forefoot after fixation, and the forefoot pushing and pulling movements can be completed smoothly during walking, without problems such as forefoot pain and uneven force distribution caused by malunion of the fracture. This makes the patient's gait more natural and stable, and comprehensively improves the performance of the foot in daily activities.

[0022] This utility model has the following beneficial effects: 1. In this utility model, different types of calcaneal plates, with unique shapes and hole distributions, can precisely fit different parts of the calcaneus and different fracture types. Through multiple round holes and screws, the fracture ends are fixed from different directions, enhancing stability. In fractures involving the calcaneal articular surface, it can help restore the smoothness of the articular surface. These plates can evenly distribute stress, reduce local stress concentration, lower the risk of complications, and promote good healing and functional recovery of calcaneal fractures.

[0023] 2. In this utility model, through the reasonable layout of the holes on each bone plate and the design that fits the anatomical shape of the calcaneus, it is possible to achieve precise reduction and stable fixation of the fracture site of the calcaneus, help restore the normal shape of the calcaneus, such as length, width, height and flatness of the articular surface, and create good conditions for fracture healing.

[0026] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Reference Figure 1 An embodiment of the present invention provides an anatomical metal bone plate, comprising a first connecting plate 1, a first branch 101 fixedly connected to the right side of the first connecting plate 1, a second branch 102 fixedly connected to the right side of the first branch 101, a third branch 103 fixedly connected to the top of the first connecting plate 1, a fourth branch 104 fixedly connected to the left side of the first connecting plate 1, and a fifth branch 105 fixedly connected to the bottom left side of the first connecting plate 1.

[0028] Specifically, this bone plate is mainly suitable for relatively simple fractures of the calcaneus body, especially fractures with relatively regular fracture lines that do not involve the calcaneal articular surface, transverse or short oblique fractures of the calcaneus body, fracture fragments with little displacement and fracture lines that do not involve the key weight-bearing areas and articular surfaces of the calcaneus. Its length and number of holes are designed to fix such relatively regular areas of the calcaneus body.

[0029] Reference Figure 1 The first connecting plate 1 has a round hole on its surface, the first branch 101 has round holes on all four sides, the second branch 102 has a round hole on its right side, the third branch 103 has two round holes at the top and bottom, the fourth branch 104 has four round holes on its surface, and the fifth branch 105 has three round holes on its surface. The angle between the third branch 103 and the first branch 101 is 125 degrees, the angle between the fourth branch 104 and the third branch 103 is 40 degrees, and the angle between the fifth branch 105 and the fourth branch 104 is 35 degrees. The first connecting plate 1, the first branch 101, the second branch 102, the third branch 103, the fourth branch 104, and the fifth branch 105 are integrally formed and have an overall length of 88 mm.

[0030] Specifically, this calcaneal plate provides relatively stable axial fixation. The plate is firmly connected to the fracture fragments with matching screws, limiting the axial displacement of the fracture fragments and maintaining the alignment of the fracture site. During the fracture healing process, it can effectively disperse stress and reduce micromovement between the fracture ends, creating a relatively stable mechanical environment for fracture healing. This helps promote callus formation and fracture healing. At the same time, this fixation method is relatively simple, the surgical operation is relatively easy, and it causes less damage to surrounding tissues, which is beneficial to the patient's postoperative recovery.

[0031] Reference Figure 2 The second connecting plate 2 is fixedly connected to the right side of the first fixing plate 201, the second connecting plate 2 is fixedly connected to the left side of the second connecting plate 202, the second fixing plate 202 is fixedly connected to the left side of the second fixing plate 202, the third fixing plate 203 is fixedly connected to the bottom of the third fixing plate 203, and the second connecting plate 2 is fixedly connected to the bottom left side of the second connecting plate 2, and the fifth fixing plate 205 is fixedly connected to the bottom left side of the second connecting plate 2.

[0032] Specifically, this bone plate is suitable for fractures of the calcaneus body with unusual fracture lines or fracture fragments that have some degree of displacement but are not too complicated. For example, some fractures involving the lateral wall of the calcaneus with oblique or spiral fracture lines that do not cause serious damage to the talocalcaneal articular surface. The specific length and structural design of this bone plate allow it to better conform to the anatomical shape of the lateral wall of the calcaneus and effectively fix fracture fragments in these special locations.

[0033] Reference Figure 2 The second connecting plate 2 has four round holes on its surface. The first fixing plate 201 has round holes at its top and bottom. The second fixing plate 202 has round holes at its top and left side. The third fixing plate 203 has round holes at its top and bottom. The fourth fixing plate 204 has a round hole at its bottom. The angle between the second fixing plate 202 and the fourth fixing plate 204 is 90 degrees. The angle between the second fixing plate 202 and the fifth fixing plate 205 is 35 degrees. The second connecting plate 2, the first fixing plate 201, the second fixing plate 202, the third fixing plate 203, the fourth fixing plate 204 and the fifth fixing plate 205 are integrally formed and have an overall length of 60 mm.

[0034] Specifically, during fixation, this calcaneal plate can achieve precise reduction and fixation of the fracture fragments by adjusting the insertion angle and position of the screws according to the specific location and displacement direction of the fracture fragments. It can provide good lateral and axial stability, preventing the fracture fragments from shifting in the horizontal and vertical directions. During the fracture healing process, this plate can help maintain the normal width and height of the calcaneus, reduce the risk of calcaneal malunion caused by fracture displacement, and thus better restore the normal anatomical structure and function of the calcaneus.

[0035] Reference Figure 3 The third connecting plate 3 has a first connecting piece 301 fixedly connected to its right side, a second connecting piece 302 fixedly connected to its bottom left side, a third connecting piece 303 fixedly connected to its left side, and a fourth connecting piece 304 fixedly connected to its left side.

[0036] Specifically, this bone plate is used for complex calcaneal fractures, especially those involving the talocalcaneal articular surface. These fractures are often accompanied by collapse and comminutedness of the talocalcaneal articular surface, and the direction and degree of displacement of the fracture fragments are quite complex. The complex structure and multiple branches of this bone plate enable it to fix the fracture fragments in multiple directions, especially for the reduction and fixation of articular surface fracture fragments. In talocalcaneal articular surface fractures, the branches of the secondary bone plate can extend below the articular surface, effectively supporting and fixing the collapsed articular surface fracture fragments and restoring the flatness of the articular surface.

[0037] Reference Figure 3The third connecting plate 3 has round holes at the bottom and right side, the first connecting piece 301 has round holes at the top and bottom, the third connecting piece 303 has three round holes on its surface, and the fourth connecting piece 304 has three round holes on its surface. The angle between the first connecting piece 301 and the second connecting piece 302 is 145 degrees, and the angle between the second connecting piece 302 and the third connecting piece 303 is 135 degrees. The third connecting plate 3, the first connecting piece 301, the second connecting piece 302, the third connecting piece 303 and the fourth connecting piece 304 are integrally formed and have an overall length of 65 mm.

[0038] Specifically, this calcaneal plate provides comprehensive stability and fixation. Through the fixation of multiple screws in different directions, the fracture fragments are firmly connected together, maximizing the restoration of the normal anatomical shape of the calcaneus and the flatness of the articular surface. During the fracture healing process, it can effectively disperse the stress on the articular surface, reducing the occurrence of traumatic arthritis and complications. At the same time, this fixation method allows patients to perform appropriate joint movements in the early postoperative period, promoting the nutrition and repair of articular cartilage and facilitating the recovery of joint function.

[0039] Reference Figure 4 The first support plate 401 is fixedly connected to the top left side of the fourth connecting plate 4, the second support plate 402 is fixedly connected to the bottom left side of the fourth connecting plate 4, the third support plate 403 is fixedly connected to the top left side of the second support plate 402, the fourth support plate 404 is fixedly connected between the first support plate 401 and the third support plate 403, and the fifth support plate 405 is fixedly connected between the first support plate 401 and the second support plate 402.

[0040] Specifically, this bone plate is suitable for fractures in specific locations of the anterior or posterior part of the calcaneus, such as fractures of the anterior calcaneal process or the calcaneal tuberosity. Due to the special anatomical structure of these fractures, bone plates of specific shapes and structures are required for fixation. The structure and specifications of this bone plate can better adapt to the anatomical characteristics of the anterior or posterior part of the calcaneus, and accurately fix the fracture fragments in these locations. In fractures of the anterior calcaneal process, this bone plate can closely conform to the shape of the anterior calcaneal process, effectively fix the fracture fragments, and prevent the fracture fragments from shifting again.

[0041] Reference Figure 4 The fourth connecting plate 4 has round holes at each of its four corners. The first support plate 401 has two round holes, the second support plate 402 has three round holes, the third support plate 403 has two round holes, and the fourth support plate 404 has one round hole. The angle between the first support plate 401 and the second support plate 402 is 45 degrees. The fourth connecting plate 4, the first support plate 401, the second support plate 402, the third support plate 403, the fourth support plate 404, and the fifth support plate 405 are integrally formed and have an overall length of 65 mm.

[0042] Specifically, this calcaneal plate provides good local stability when fixing fractures of the anterior or posterior part of the calcaneus. With proper screw placement, the fracture fragments are firmly fixed to the plate. During the fracture healing process, it can reduce micromovement at the fracture site and promote fracture healing. At the same time, due to its targeted design, it has less interference with surrounding tissues, which is beneficial to the postoperative recovery of patients. It can better restore the function of the calcaneus in these specific locations and reduce foot dysfunction caused by fractures.

[0043] Working principle: When faced with different types of calcaneal fractures, users will select appropriate anatomical metal bone plates based on the specific characteristics of the fracture. For transverse or short oblique fractures where the calcaneal body is relatively simple, the fracture line is regular, the calcaneal joint surface is not involved, the displacement is not obvious, and the key weight-bearing area and joint surface are not involved, a bone plate with a length of 88 mm and consisting of a first connecting plate 1, a first branch 101, a second branch 102, a third branch 103, a fourth branch 104, and a fifth branch 105 will be selected. By screwing in the matching screws through the round holes in the first connecting plate 1 and each branch, the fracture fragments can be axially fixed, axial displacement can be restricted, the alignment of the fracture site can be maintained, stress can be distributed, micromovement of the fracture ends can be reduced, and callus formation and fracture healing can be promoted. In cases where the fracture line of the calcaneus body is in a special location, the fracture fragments have some displacement but are not too complex, such as oblique or spiral fractures involving the lateral wall of the calcaneus without serious damage to the talocalcaneal joint surface, a 60mm long bone plate with a single piece is selected. This plate includes a second connecting plate 2, a first fixation plate 201, a second fixation plate 202, a third fixation plate 203, a fourth fixation plate 204, and a fifth fixation plate 205. Based on the location and displacement direction of the fracture fragments, the screw insertion angle and position are adjusted through the round holes on the second connecting plate 2 and each fixation plate to achieve precise reduction and fixation, provide lateral and axial stability, maintain the normal width and height of the calcaneus, and reduce the risk of malunion. In complex calcaneal fractures involving the calcaneal articular surface, accompanied by collapse, comminuted fractures, and complex displacement of fracture fragments, a 65mm long, integrally molded bone plate containing a third connecting plate 3, a first connecting piece 301, a second connecting piece 302, a third connecting piece 303, and a fourth connecting piece 304 is used. Utilizing the round holes at each location, multiple screws are used to fix the fracture fragments in different directions, effectively supporting and reducing the fracture fragments on the articular surface, providing all-round stable fixation, restoring the anatomical shape of the calcaneus and the flatness of the articular surface, dispersing the stress on the articular surface, reducing complications, and facilitating early joint movement and functional recovery; For fractures of the anterior or posterior parts of the calcaneus, such as anterior protrusions or tubercles, a 65mm long, integrally molded bone plate containing a fourth connecting plate 4, a first support plate 401, a second support plate 402, a third support plate 403, a fourth support plate 404, and a fifth support plate 405 is used. Screws are strategically placed through the round holes on the fourth connecting plate 4 and each support plate to precisely fix the fracture fragments, providing good local stability, reducing micromovement at the fracture site, promoting healing, minimizing interference with surrounding tissues, restoring function in the specific area, and reducing foot dysfunction.
