Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically a protective plate for hallux valgus osteotomy surgery. Background Technology
[0002] Traditional small-incision hallux valgus osteotomy correction surgery generally requires the use of a bone drill to penetrate the cancellous and cortical bone of the first metatarsal and perform osteotomy to correct the hallux valgus deformity. However, because the incision is small (about 1 cm), it cannot expose the lateral surgical field of the first metatarsal, which is a blind spot. Therefore, when the bone drill penetrates the bone and performs osteotomy, the exposed part of the bone drill, while rotating continuously, will become entangled in the myofascia, soft tissue, nerves, and blood vessels in the vicinity of the surgical blind spot. This can lead to serious complications such as bleeding, damage to myofascia, soft tissue, and blood vessels, which contradicts the concept of minimally invasive foot surgery and affects the degree of foot health recovery. Utility Model Content
[0003] (a) Technical problems to be solved
[0004] To address the shortcomings of existing technologies, this utility model provides a protective plate for hallux valgus osteotomy surgery, which solves the problems mentioned in the background art.
[0005] (II) Technical Solution
[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a protective plate for hallux valgus osteotomy surgery, comprising a blocking plate and a connecting handle. The blocking plate has a certain degree of flexibility and strength, and its shape is adapted to the anatomical structure of the foot so as to fit closely. The connecting handle is made of stainless steel and is a straight cuboid. The connecting handle is connected to the top of one side of the blocking plate.
[0007] Preferably, the baffle is made of medical-grade rubber or stainless steel.
[0008] Preferably, the middle section of the barrier is a curved rectangle with an angle of 1 arc degree ≈ 57.3°. The rectangle is 1.5 cm long, 1.0 cm wide, and 2 mm thick. The edges of the barrier are rounded to avoid damaging the patient's skin and improve the patient's comfort.
[0009] Preferably, the connecting handle is 3 cm long, 3 mm wide, and 2 mm thick. The outer surface of the connecting handle is polished smooth and the edges and corners are blunted to avoid damaging the patient's skin and improve the patient's comfort.
[0010] Preferably, the baffle plate and the connecting handle are integrally connected at a 90° angle, and the distance between the end of the baffle plate and the middle position of the baffle plate is 1.5 cm.
[0011] Preferably, the blocking plate wraps around the metatarsals of the foot from the bottom. The blocking plate can isolate the myofascia, soft tissue and nerves around the metatarsals and prevent accidental injury from the bone drill.
[0012] This utility model provides a protective plate for hallux valgus osteotomy surgery, which has the following beneficial effects:
[0013] 1. The protective plate used in hallux valgus osteotomy surgery, through the setting of the blocking plate, enables the protective plate to avoid the bone drill from causing collateral damage to the myofascia, soft tissue, nerves and blood vessels. By separating the metatarsal bones of the foot from the surrounding myofascia, soft tissue, nerves and blood vessels, the bone drill that penetrates the bone and rotates continuously can be prevented from getting entangled in the myofascia, soft tissue, nerves and blood vessels near the surgical blind area, thereby avoiding collateral damage.
[0014] 2. The protective plate used in hallux valgus osteotomy surgery, through the cooperation of the blocking plate and the connecting handle, makes the protective plate easy to insert and remove, reducing damage. Because the blocking plate has a certain degree of flexibility and strength and its shape is adapted to the anatomical structure of the foot, it can fit closely. Therefore, it can be manually folded and unfolded to restore its original shape. Thus, it can be easily inserted into the outside of the osteotomy area with only a small visible incision and unfolds to wrap around the metatarsal bone, which is very convenient. Since no additional fixation structure is needed after the blocking plate is inserted, the blocking plate can be removed simply by lifting the connecting handle, which is very convenient. Due to the small incision, the damage is minimal. Attached Figure Description
[0015] Figure 1 This is a structural schematic diagram of the three-dimensional view of this utility model.
[0016] In the diagram: 1. Baffle plate; 2. Connecting handle. Detailed Implementation
[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0018] Please see Figure 1This utility model provides a technical solution: a protective plate for hallux valgus osteotomy surgery, including a blocking plate 1 and a connecting handle 2. The blocking plate 1 has a certain degree of flexibility and strength, and its shape is adapted to the anatomical structure of the foot so as to fit closely. The connecting handle 2 is made of stainless steel and is a straight rectangular prism. The connecting handle 2 is connected to the top of one side of the blocking plate 1. The blocking plate 1 is made of medical-grade rubber or stainless steel, specifically medical-grade silicone rubber or stainless steel, and its color is blue, green, or colorless, etc. The middle section of the blocking plate 1 is a curved rectangle with an angle of 1 arc degree ≈ 57.3° and a length of 1.5 cm. The width is 1.0 cm and the thickness is 2 mm. The edges of the blocking plate 1 are rounded to avoid damage to the patient's skin and improve patient comfort. The connecting handle 2 is 3 cm long, 3 mm wide and 2 mm thick. The outer surface of the connecting handle 2 is polished and the edges are blunted to avoid damage to the patient's skin and improve patient comfort. The blocking plate 1 and the connecting handle 2 are connected at a 90° angle. The distance between the end of the blocking plate 1 and the middle position of the blocking plate 1 is 1.5 cm. The blocking plate 1 wraps around the metatarsals of the foot from the bottom. The blocking plate 1 can isolate the myofascia, soft tissue and nerve blood around the metatarsals of the foot and avoid accidental injury by the bone drill.
[0019] When using this device, first select a protective plate of appropriate size according to the size of the patient's metatarsals. The shape and size of the curved plate 1 should approximate the shape and size of the metatarsals. During the surgery, first, make a small, visible incision of about 5mm above the gap between the metatarsals, based on the location of the osteotomy. Then, pinch the plate 1 towards the center to narrow its width, and slowly insert it through the visible incision. The insertion angle is the angle at which the plate 1 wraps around the outside of the metatarsals. During this process, the outer end of the plate 1 is slowly inserted along the outer side of the metatarsals. Because the plate 1 has the ability to self-correct, once it is inserted under the metatarsals... When the baffle plate 1 is inserted, its outer end is already attached to the lower surface of the metatarsal bone and wraps around the metatarsal bone from bottom to top. Thus, the baffle plate 1 wraps around the lower part of the metatarsal bone, separating the myofascia, soft tissue, and nerves and blood vessels. At this time, even if the bone drill penetrates the metatarsal bone, it will not continue to damage the myofascia, soft tissue, and nerves and blood vessels below. This achieves the function of protecting the myofascia, soft tissue, and nerves and blood vessels in the blind area below the metatarsal bone. After the operation is completed, the baffle plate 1 can be slowly pulled out upwards through the connecting handle 2. During this process, since the baffle plate 1 can be deformed under force, only a very small incision is needed to insert the baffle plate 1, thereby reducing damage.
[0020] In summary, the protective plate used in this hallux valgus osteotomy separates the metatarsal bones of the foot from the surrounding myofascia, soft tissues, and nerves and blood vessels through the blocking plate 1. This avoids the bone drill bit, which penetrates the bone and rotates continuously, from entangled in the myofascia, soft tissues, and nerves and blood vessels near the surgical blind spot, thus preventing collateral damage. Because the blocking plate 1 has a certain degree of flexibility and strength and its shape is adapted to the anatomical structure of the foot, it can fit closely. Therefore, it can be manually folded and unfolded to restore its original shape. Thus, it can be easily inserted into the outer side of the osteotomy area and unfolded to wrap around the metatarsal bones with only a small, visible incision, which is very convenient. Since no additional fixation structure is needed after the blocking plate 1 is inserted, the blocking plate 1 can be removed simply by lifting the connecting handle 2, which is very convenient. Due to the small incision, the damage is minimal.
[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
