Description

Technical Field

[0001] This invention relates to the field of medical stent technology, and in particular to a medical external fixation structure and medical external fixation components. Background Technology

[0002] Fractures and deformities of the phalanges, metacarpals, metatarsals, radius, and ulna are common orthopedic conditions. The core goal of clinical treatment is to achieve reliable fixation of the fracture ends / corrected areas, reduce complications, enable early functional exercises, and promote bone healing and limb function recovery. Currently, commonly used fixation methods include internal fixation with mini-plates and screws, and a combination of Kirschner wires and external fixators. Internal fixation with mini-plates and screws typically requires open reduction and dissection of the periosteum and soft tissue, easily leading to complications such as tendon adhesions, joint stiffness, and postoperative infection. It is also poorly suited for open fractures and severe comminuted fractures, requiring secondary surgery to remove the internal fixation in some patients. The combination of Kirschner wires and external fixators, such as the variable stiffness external fixation device for accelerating lower limb fracture healing disclosed in Chinese Patent Publication CN121570232A, usually relies on mechanical clamps to lock the Kirschner wires. These solutions are generally complex in structure, have numerous parts, and involve large external fixators, resulting in poor wearing comfort, significantly impacting patients' lives, and making it difficult to simultaneously meet the needs of early functional exercises at the injured site. Therefore, there is an urgent need for an external fixation device that is structurally simple, reliably fixed, and capable of restoring the function of the injured area. Summary of the Invention

[0003] The technical problem that this invention aims to solve is that existing medical external fixation structures are complex, have many parts, and are large in size, resulting in poor wearing comfort.

[0004] To address the aforementioned technical problems, the present invention provides a medical external fixation structure, comprising: Multiple fixation needles, each comprising a first segment and a second segment connected to each other, wherein the end of the first segment furthest from the second segment is a pointed tip for puncturing the site to be fixed, and the second segment is inclined to the first segment; A storage device, wherein the end of the second segment away from the first segment is inserted into the storage device and fixed to the storage device.

[0005] According to one embodiment of the present invention, the storage device and the first segment are spaced apart in a third direction, so that an operating space is formed between the storage device and the first segment.

[0006] According to one embodiment of the present invention, a bend is formed at the connection between the first segment and the second segment, the bend extending in a first direction toward the side away from the operating space, and the plurality of fixing needles are divided into a first needle group and a second needle group distributed at intervals along the first direction, the bend of the first needle group extending in the opposite direction to the bend of the second needle group, wherein the first direction is perpendicular to the third direction.

[0007] According to one embodiment of the present invention, the storage device has a first region, the second segment includes a first end and a second end, the first ends of a plurality of fixing pins are spaced apart in the second direction, the second ends of a plurality of fixing pins are located in the first region and are close to each other, and the first direction, the second direction and the third direction are perpendicular to each other.

[0008] According to one embodiment of the present invention, at least one of the fixing needles in the first needle group and at least one of the fixing needles in the second needle group are arranged adjacent to each other in their first segments.

[0009] According to one embodiment of the present invention, the storage device includes a box body and a solidified block, the solidified block being disposed in the box body, the end of the second segment away from the first segment penetrating the box body, the wall of the box body being able to be sealed to the second segment, and the solidified block being connected and fixed to the second segment.

[0010] According to one embodiment of the present invention, the outer contour of the storage device is rectangular, spindle-shaped, spherical, or capsule-shaped.

[0011] The present invention also provides a medical external fixation component, comprising: At least two medical external fixation structures as described above; At least one positioning element, one end of which is connected to any one of the medical external fixation structures and the other end of which is connected to another medical external fixation structure, to define the relative position of two adjacent medical external fixation structures.

[0012] According to one embodiment of the present invention, the positioning member is connected to the storage device.

[0013] According to one embodiment of the present invention, at least one of the positioning elements is a rigid structure, or at least one of the positioning elements is an elastic structure, or there are at least two positioning elements, and at least one of the positioning elements is a rigid structure and at least one of the positioning elements is an elastic structure.

[0014] The medical external fixation structure of this invention fixes the fixation needles by tilting the first and second segments of the fixation needles, inserting the second segments of multiple fixation needles into a storage device, and fixing the second segments to the storage device. This greatly simplifies the medical external fixation structure, involves fewer parts, is more convenient to wear and use, and reduces the size of the medical external fixation structure, thus minimizing its impact on the patient. Furthermore, the smooth outer surface of the storage device prevents the medical external fixation structure from snagging on clothing or external objects during use. This reduces the impact of the medical external fixation structure on the patient's life and improves user comfort.

[0015] The medical external fixation component of this invention provides two or more medical external fixation structures, which are connected to form a stable whole by positioning components. This is used to coordinate the fixation of the target site, improve the fixation stability of the target site, facilitate the healing and functional recovery of the target site, reduce interference between the medical external fixation structure and the external structure, and improve user comfort.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0025] like Figure 1 and Figure 2 As shown, a medical external fixation structure 100 according to an embodiment of the present invention includes a storage device 120 and a plurality of fixation needles 110.

[0026] Specifically, the fixing needle 110 includes a first segment 111 and a second segment 112 connected to each other. The end of the first segment 111 away from the second segment 112 is a pointed tip for piercing the area to be fixed. The second segment 112 is inclined to the first segment 111, and a bend 113 is formed between the first segment 111 and the second segment 112 of the fixing needle 110. The end of the second segment 112 away from the first segment 111 passes through a receiving device 120 and is fixed to the receiving device 120, thereby defining the relative positions of the plurality of fixing needles 110. Figure 2As shown, when using the medical external fixation structure 100, the first segment 111 of multiple fixation pins 110 is inserted into the target fixation site 200, and the second segment 112 of multiple fixation pins 110 is inclined to its own first segment 111 and stored and fixed in the storage device 120, thereby fixing the relative position between the multiple fixation pins 110, and thus fixing the position of the bone in the target fixation site 200.

[0027] Compared to existing technologies that rely on mechanical clamps to lock the fixation pin 110, this application uses a storage device 120 to fix the fixation pin 110. This involves fewer parts, has a simpler structure, and is more convenient to wear and use. Furthermore, it concentrates the second segment 112 of the fixation pin 110 within a specific area, reducing the volume of the medical external fixation structure 100. In addition, the outer surface of the storage device 120 is smoother than that of mechanical clamps, preventing the medical external fixation structure 100 from snagging with clothing or external objects during use. This reduces the impact of the medical external fixation structure 100 on the patient's life and improves user comfort.

[0028] According to an embodiment of the present invention, the medical external fixation structure 100 fixes the fixation needles 110 by tilting the first segment 111 and the second segment 112 of the fixation needles 110, and by inserting the second segment 112 of a plurality of fixation needles 110 into a storage device 120 and fixing the second segment 112 to the storage device 120. This greatly simplifies the medical external fixation structure 100, involves fewer parts, is more convenient to wear and use, and reduces the size of the medical external fixation structure 100, thus reducing its impact on the patient. Furthermore, the outer surface of the storage device 120 is smooth, preventing the medical external fixation structure 100 from snagging with clothing or external objects during use. This reduces the impact of the medical external fixation structure 100 on the patient's life and improves user comfort.

[0029] According to some embodiments of this application, the storage device 120 includes a box body 123 and a solidified block 121 disposed within the box body 123. The end of the second segment 112 away from the first segment 111 penetrates into the box body 123 and is connected and fixed to the solidified block 121. The wall of the box body 123 can be sealed to the second segment 112, so that the interior of the box body 123 remains sealed after the fixing pin 110 is connected to the box body 123. The solidified block 121 is formed by filling the box body 123 with liquid solidifying material and solidifying and hardening. The wall of the box body can be punctured by the second segment 112, and the punctured area of ​​the wall of the box body 123 can self-recover, so that the wall of the box body 123 is sealed to the second segment 112, thereby preventing leakage after the solidifying agent is injected into the box body 123. The box body 123 can be a box body with an open top side, or the box body 123 can include a box body and a lid, with the solidified block 121 disposed inside the box body and the lid covering the box body, thereby separating the solidified block 121 from the outside.

[0030] The coagulation block 121 is connected and fixed to the second segment 112 to secure the second segment 112, thereby defining the relative positions of the plurality of fixing pins 110. In some embodiments, the end of the second segment 112 away from the first segment 111 is located inside the coagulation block 121, that is, the end face of the second segment 112 away from the first segment 111 is located inside the coagulation block 121 or flush with the surface of the coagulation block 121, so that the end of the second segment 112 away from the first segment 111 does not protrude from the surface of the coagulation block 121, thereby preventing the second segment 112 from getting caught on clothing and preventing the end of the second segment 112 from causing damage to other parts of the patient, thus improving the comfort of use.

[0031] According to some embodiments of the present invention, the storage device 120 and the first segment 111 are spaced apart in the third direction Z, and a three-dimensional operating space 130 is formed between the storage device 120 and the first segment 111, thereby allowing adjustment of the storage device 120 and the fixing pin 110 through the operating space 130. Specifically, as Figure 2 As shown, the first segment 111 of multiple fixing pins 110 is distributed along the second direction Y, and the storage device 120 and the fixing pins 110 are spaced apart along the third direction Z to form a three-dimensional operating space 130, wherein the second direction Y is perpendicular to the third direction Z.

[0032] According to some embodiments of this application, a bent portion 113 is formed at the connection between the first segment 111 and the second segment 112. The bent portion 113 extends in the first direction X toward the side away from the operating space 130. Furthermore, the plurality of fixation needles 110 are divided into a first needle group and a second needle group. The bending portion 113 of the first needle group extends in the opposite direction to the bending portion 113 of the second needle group. The first direction X is perpendicular to the third direction Z to improve the stability of the medical external fixation structure 100. Specifically, the multiple fixation needles 110 are divided into a first needle group and a second needle group. In the first needle group, the bent portion 113 extends towards one end in the first direction X, and in the second needle group, the bent portion 113 extends towards the other end in the first direction X. This allows the second segment 112 of the first needle group to enter the receiving device 120 from the side away from the second needle group, and the second segment 112 of the second needle group to enter the receiving device 120 from the side away from the first needle group. Thus, in a cross-section perpendicular to the second direction Y, the first needle group and the second needle group form an approximately triangular structure, improving the stability of the medical external fixation structure 100. It should be noted that the bending portion 113 extending towards the first direction includes the case where the extension direction of the bending portion 113 is parallel to the first direction X, and the case where the component of the extension direction of the bending portion 113 in the first direction X is not zero. In some embodiments, at least one fixation needle 110 in the first needle group and at least one fixation needle 110 in the second needle group are arranged with their first segments 111 adjacent to each other, so that the medical external fixation structure 100 can more firmly fix the target fixation site 200. For example, such as Figure 3As shown, the target fixation site 200 includes two bone segments distributed in the second direction Y. In the first direction X, the bent portion 113 of the first needle group is located on one side of the target fixation site 200, and the bent portion 113 of the second needle group is located on the other side of the target fixation site 200. One fixation needle 110 in the first needle group and one fixation needle 110 in the second needle group are arranged adjacently in the second direction Y and puncture the same bone segment to form an approximately triangular fixation structure for the bone segment.

[0033] According to some embodiments of this application, the storage device 120 has a first region, the projection of the first region in the third direction Z at least partially covering the center of gravity of the storage device 120, and the second segment 112 includes a first end and a second end, wherein the first end is connected to the bending portion 113, and the second end is away from the first segment. The first ends of a plurality of fixation pins 110 are spaced apart in the second direction Y, and the second ends of the plurality of fixation pins 110 are located in the first region and close to each other, thereby forming an approximately pyramidal structure in the second segment 112 of the plurality of fixation pins 110, further improving the stability of the medical external fixation structure 100, making the structure of the medical external fixation structure 100 more compact, reducing its volume, and reducing the impact on the patient.

[0034] In some embodiments, the distance between the storage device 120 and the first segment 111 in the third direction Z is L, where 5mm ≤ L ≤ 50mm. This ensures that the height of the operating space 130 in the third direction Z allows for convenient operation and adjustment of the storage device 120 and the fixing pins 110, and also ensures the stability of the connection between the storage device 120 and the multiple fixing pins 110. Furthermore, it preserves the space for movement between the storage device 120 and the outer surface of the target fixation part 200, facilitating observation and allowing the target fixation part 200 to move within a certain range, meeting the needs of functional recovery of the injured area.

[0035] According to some embodiments of the present invention, the first segment 111 extends along the first direction X, and the orthographic projection of the receiving device 120 on the third direction Z at least partially falls on the target fixation part 200, wherein the first direction X, the second direction Y, and the third direction Z are mutually perpendicular. This allows the medical external fixation structure 100 to conform to the outer contour of the target fixation part 200, reducing the impact on the patient. It should be noted that the above-mentioned first segment 111 extending along the first direction X includes the case where the extension direction of the first segment 111 is parallel to the first direction X, and the case where the component of the extension direction of the first segment 111 in the first direction X is not zero.

[0036] According to some embodiments of the present invention, the box body 123 is made of silicone rubber, or TPE (Thermoplastic Elastomer), or TPU (Thermoplastic Polyurethane Elastomer), or acrylic foam. These materials have high elasticity, high resilience and good closed-cell structure, which makes the wall of the box body 123 elastic, so that the punctured area of ​​the wall of the box body 123 can recover itself. When the second segment 112 passes through the wall of the box body 123, the wall of the box body 123 can rely on its own elastic contraction to tightly wrap the outer wall of the second segment 112, forming an annular elastic seal. Thus, when liquid curing material is injected to form solidified block 121, it can ensure no leakage, no glue overflow, and no skin contamination, while ensuring the dimensional stability of the medical external fixation structure 100. After the second section 112 is pulled out, the hole on the wall can close automatically, thus allowing the box 123 to be reused and reducing waste.

[0037] In some embodiments, the outer contour of the storage device 120 is rectangular, which is convenient to manufacture; or, the outer contour of the storage device 120 may be spindle-shaped, spherical or capsule-shaped, so that the outer contour of the storage device 120 is smoother and fits the human body better, reducing the impact on the patient's life and improving the comfort of use.

[0038] like Figure 4 As shown, a medical external fixation assembly according to an embodiment of the present invention includes at least two medical external fixation structures 100 as described above and at least one positioning member 122. One end of the positioning member 122 is connected to any one of the medical external fixation structures 100, and the other end is connected to another medical external fixation structure 100, thereby defining the relative position of two adjacent medical external fixation structures 100, so that the two or more medical external fixation structures 100 form a stable whole, and reduce interference between the medical external fixation structure 100 and external structures, thereby improving user comfort. For example, in Figure 4In the example, the medical external fixation assembly includes four arrayed medical external fixation structures 100, with adjacent medical external fixation structures 100 connected by positioning elements 122. It is understood that when it is necessary to fix two or more adjacent sites, such as adjacent fingers or different parts of the same finger, corresponding medical external fixation structures 100 are set for different target fixation sites 200 to improve the fixation stability of the target fixation site 200, thereby facilitating bone healing and functional recovery. The two ends of the positioning element 122 are respectively connected to the storage device 120 of the corresponding medical external fixation structure 100. Furthermore, the positioning element 122 passes through the wall of the box 123 and is connected and fixed to the solidification block 121, making operation more convenient during the fixation process.

[0039] According to some embodiments of the present invention, at least one positioning member 122 is a rigid structure to improve the stability of the connection between the medical external fixation structures 100, thereby improving the fixation effect on the target fixation site 200. The rigid positioning member 122 ensures that the relative position between two adjacent medical external fixation structures 100 remains fixed. Alternatively, in some embodiments, at least one positioning member 122 is an elastic structure, made of one of silicone rubber, thermoplastic elastomer, thermoplastic polyurethane, or acrylic foam material. The positioning member 122 has good elastic properties, allowing the two medical external fixation structures 100 connected by the positioning member 122 to move relative to each other within a certain range, thereby allowing the corresponding fixed target fixation site 200 to move within a certain range. Alternatively, in some embodiments, there are at least two positioning members 122, wherein at least one positioning member 122 is a rigid structure and at least one positioning member 122 is an elastic structure.

[0040] In practical use, positioning elements 122 made of different materials can be selected according to needs. For example, when the fracture length is long, multiple medical external fixation structures 100 can be used for fixation. Adjacent medical external fixation structures 100 are connected by rigid positioning elements 122 to keep the relative positions of multiple medical external fixation structures 100 fixed. As another example, when it is necessary to fix two relatively movable target fixation parts 200, the two target fixation parts 200 are fixed by corresponding medical external fixation structures 100 respectively. The two medical external fixation structures 100 are connected by elastic positioning elements 122, so that the two target fixation parts 200 can move relative to each other within a certain range, which is conducive to bone healing and functional recovery.

[0041] The process of using this invention is as follows: The tips of the first segments 111 of a plurality of fixing pins 110 are passed through the target fixing portion 200. The fixing pins 110 are then bent such that the second segments 112 of the fixing pins 110 are inclined relative to the first segments 111, and the second ends of the plurality of fixing pins 110 are brought close to each other. The angle between the second segment 112 and the first segment 111 is A, 30°≤A≤135°. The second segment 112 is then passed through the wall of the housing 123, such that at least a portion of the second segment 112 is located within the housing 123. Figure 3 As shown, to improve the fixation effect of the medical external fixation structure 100 on the target fixation site 200, the first segment 111 of at least one fixation needle 110 is inserted through the cross-section of two fractured bones. After the second segment 112 is inserted into the housing 123, a liquid curing material is injected into the housing 123, and at least a portion of the second segment 112 is immersed in the liquid curing material, causing the liquid curing material to solidify into a solidified block 121, thereby connecting and fixing the second segment 112 inserted into the housing 123 to the solidified block 121. During the process of solidifying the liquid curing material into the solidified block 121, an ultraviolet lamp can be used to irradiate the curing material in the housing 123 for a preset time to accelerate the solidification of the curing material. Afterwards, the end of the second segment 112 of the plurality of fixation needles away from the first segment 111 is trimmed so that the second end does not protrude from the surface of the housing 123 or the solidified block 121.

[0042] In summary, the embodiments of the present invention provide a medical external fixation structure 100, which has at least the following advantages: 1. The structure is simplified, with fewer parts and a smaller size, making installation and use more convenient and greatly reducing the impact on patients' daily lives.

[0043] 2. The outer surface of the storage device 120 is smooth, which prevents the medical external fixation structure 100 from getting caught on clothing or external items during use, thus improving the comfort of use.

[0044] 3. It can form a three-dimensional operating space 130, which is convenient for adjustment during installation and can provide a certain amount of movement space for the target fixed part 200, which is conducive to the functional recovery of the injured part.

[0045] Finally, it should be noted that the above embodiments are only for illustrating the present invention and are not intended to limit the present invention. It should be pointed out that those skilled in the art can make several improvements and substitutions without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
