Description

Technical Field

[0001] The present invention relates to a medical device, in particular to a kit composed of a plurality of products, which can limit abnormal blood vessels to prevent further expansion and facilitate the closure of the abnormal blood vessels. Background Art

[0002] Hernia is a condition in which an organ or part of an organ in the body moves out of its normal anatomical position and enters another part of the body through a congenital or acquired weakness or herniation. Its main symptoms include a mass protruding from the body surface, and the size of the mass may change as the body position changes.

[0003] Hemangiomas / vascular malformations affect the skin and deeper tissues, including tendons, muscles, nerves, and even bones. Hemangiomas occurring in the oral and maxillofacial regions account for approximately 60% of all hemangiomas in the body, most of which occur in the skin and subcutaneous tissue of the face and neck, and very few occur in the oral mucosa. Hemangiomas deep in the jaw are currently considered vascular malformations.

[0004] Clinically, it is found that, on the one hand, if the subcutaneous vascular malformation is allowed to expand, it will not only gradually protrude on the epidermis, affecting the appearance, but also cause fascial hernia and periosteal hernia, which are harmful to health. For this, surgery is usually required to remove the vascular malformation, but for diffuse vascular malformations, surgery is often unable to completely remove them, and interventional sclerosis requires repeated treatments, which takes a long treatment period and is expensive. Summary of the invention

[0005] One object of the present invention is to provide a kit for fascia repair, which limits the growth space of abnormal blood vessels to prevent further expansion and protrusion on the epidermis.

[0006] Another object of the present invention is to provide a kit for fascia repair, which limits the growth space of abnormal blood vessels and facilitates the closure of abnormal blood vessels.

[0007] Another object of the present invention is to provide a kit for preparing a medical device for treating fascial and periosteal hernia repair, thereby solving the problem of fascial and periosteal hernia caused by expansion of vascular malformations.

[0008] Another object of the present invention is to provide a medical device for fascia repair to solve the problem of fascia and periosteal hernia caused by expansion of vascular malformations.

[0009] A kit for fascia repair, comprising:

[0010] Vascular dressing, in sheet form, the main body of which is used to cover deformed blood vessels;

[0011] One end of the fixing piece is fixed in the bone tissue, and the other end is connected to the vascular dressing, defining the gap between the vascular dressing and the abnormal blood vessel, thereby limiting the growth space of the abnormal blood vessel.

[0012] Another kit for fascia repair also includes a locking piece, which is assembled with the fixing piece so that the vascular dressing is firmly connected to the fixing piece and is not (easy) to be removed.

[0013] Another kit for fascia repair includes:

[0014] Vascular dressing, in sheet form, the main body of which is used to cover deformed blood vessels;

[0015] The fixing piece is connected with the vascular dressing to define the gap between the vascular dressing and the abnormal blood vessel, limiting the growth space of the abnormal blood vessel, and comprises a fixing seat and a fixing body. The fixing body is inserted into the bone tissue, and the vascular dressing is arranged in the fixing seat.

[0016] Another kit for fascia repair includes:

[0017] Vascular dressing, in sheet form, the main body of which is used to cover deformed blood vessels;

[0018] A fixing piece, which is connected to the vascular dressing to define the gap between the vascular dressing and the malformed blood vessel, and to limit the growth space of the malformed blood vessel, comprises a fixing seat and a fixing body, the fixing body is deeply inserted into the bone tissue, and the vascular dressing is arranged in the fixing seat;

[0019] The locking piece is assembled in the fixing piece and clamps the vascular dressing between the fixing piece and the locking piece.

[0020] The kit for fascia repair also includes a fixing cavity arranged along the axial direction of the fixing seat. A fixing groove is also arranged on the inner wall of the fixing cavity for accommodating a vascular dressing, which is conducive to the vascular dressing being more firmly connected to the fixing piece.

[0021] The fixing cavity comprises a receiving area and a buckle pin area. The receiving area is used to accommodate the main body of the locking component, and the buckle pin area is used to form a stable connection between the locking component and the fixing component.

[0022] In the direction in which the locking element is placed into the fixing cavity, the receiving area is located in the front and the buckle area is located in the rear.

[0023] A specific implementation of a locking component includes an assembly force-applying end and a locking end. The assembly force-applying end is a functional end provided for the purpose of assembly and for the convenience of applying external force. The locking end is located at the leading end in the direction in which the locking component is placed into the fixing cavity, and a locking key is provided on the locking end. The locking key moves (e.g., rotates) in the buckle pin area, and the locking key contacts (e.g., surface contacts) or disengages from the inner wall of the buckle pin area, thereby realizing the connection and separation of the locking component and the fixing component.

[0024] When the locking part is placed in the fixed cavity, a force is applied to the assembly force-applying end, and the locking key moves (for example, rotates or moves linearly) and enters the buckle pin area, and the locking key contacts the inner wall of the buckle pin area, thereby realizing the connection between the locking part and the fixed part. When the assembly force-applying end is subjected to force (for example, pressing or rotating), the locking key located in the buckle pin area moves (for example, rotates or moves linearly), and the contact surface between the locking key and the inner wall of the buckle pin area is separated, and the locking key is removed from the buckle pin area, thereby realizing the separation of the locking part and the fixed part, and at the same time, the locking part can be taken out of the fixed cavity.

[0025] The locking key also includes a locking surface, which is arranged facing the assembly force application end. The locking surface is tilted, for example: the radial angle with the locking member is greater than 0° and less than or equal to 45°, or greater than 0° and less than or equal to 35°, or greater than 0° and less than or equal to 25°, or greater than 0° and less than or equal to 15°, or greater than 0° and less than or equal to 10°.

[0026] Another specific implementation of the locking member includes an assembly force-applying end, a locking end, and an assembly flap, wherein one end of the assembly flap is connected to the assembly force-applying end, and the other end is connected to the locking end.

[0027] The locking piece includes 2 assembly flaps, or more, such as 3-4 flaps, with gaps between the assembly flaps, which, on the one hand, facilitate the vascular dressing to be accommodated therein and more firmly connected to the fixing piece. On the other hand, it provides a space for the assembly flaps to deform elastically in the radial direction, enhances the locking effect between the locking end and the buckle pin area, and forms a tight and stable connection.

[0028] In a kit for fascia repair, there are usually more than two fixing members and the same number of locking members as the fixing members. The fixing members and the locking members are assembled one by one.

[0029] Beneficial effects achieved by the technical solution of the present invention:

[0030] The present invention applies a kit consisting of several products to the treatment of vascular malformations, especially diffuse vascular malformations, thereby improving the efficiency of treatment. Vascular dressings, such as but not limited to thin fabrics, (biocompatible) non-woven fabrics or films, are covered on the blood vessels to increase the contact area with the blood vessels, especially diffuse vascular malformations, and then connected to the fixing parts to reduce or suppress the space for the expansion of vascular malformations, so that they no longer protrude on the epidermis, effectively reducing the occurrence of fascial hernia and periosteal hernia.

[0031] Because the space for expansion of vascular malformations is reduced or suppressed, further expansion of the malformed blood vessels is limited, and even closure of the malformed blood vessels is achieved, reducing the necessity of subsequent surgery. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The technical solution of the present invention is described in detail below with reference to the accompanying drawings. The embodiments of the present invention are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solution of the invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.

[0042] Figure 5 A schematic diagram of an embodiment of the kit of the present invention for treating vascular malformations, Figure 6 for Figure 5 Another angle diagram is shown. Figure 7 for Figure 5 The AA section view is shown. Figure 5 , Figure 6 and Figure 7As shown, the kit of the present invention includes a vascular dressing 300, the main body of which is used to cover the malformed blood vessel 10 and is in the form of a thin sheet. Common forms include, but are not limited to, fabrics, non-woven fabrics, electrostatically spun fabrics or films, etc., which increase the coverage area of ​​the malformed blood vessel and are also conducive to wrapping the malformed blood vessel to limit the expansion of the malformed blood vessel. The edge or part of the vascular dressing 300 is connected to the fixing member 100, and the other end of the fixing member 100 is fixed (for example, nailed or drilled) in the bone tissue 20, so that the vascular dressing 300 maintains the area and area of ​​the malformed blood vessel covered, and at the same time defines the gap 30 between the vascular dressing and the malformed blood vessel to limit the growth range of the malformed blood vessel. The locking member 200 is assembled with the fixing member 100, so that the vascular dressing 300 is firmly connected to the fixing member 200, not easy to fall out, and the area and area of ​​the malformed blood vessel covered by the vascular dressing 300 are maintained.

[0043] In the kit of this embodiment, there are usually more than two fixing members 100 and the same number of locking members 200. The fixing members 100 and the locking members 200 are assembled one by one. When the vascular dressing 300 is used to wrap the malformed blood vessel, only one fixing member 100 and one locking member 200 can be used to maintain the area and size of the malformed blood vessel wrapped by the vascular dressing 300.

[0044] Figure 1 A cross-sectional view of an embodiment of the assembly of the fixing member and the locking member of the kit of the present invention, Figure 2 for Figure 1 QQ section view shown, Figure 3 A cross-sectional view of another embodiment of the assembly of the fixing member and the locking member of the kit of the present invention, Figure 4 FIG. 1 is a schematic diagram of an embodiment of a locking member of a kit of the present invention. Figure 5 and Figure 6 ,like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the fixing member 100 includes a fixing seat 110 and a fixing body 120. The fixing body 120 is deeply inserted into the bone tissue, which is conducive to determining the position of the fixing member 100 and prevents it from changing. The vascular dressing is arranged in the fixing seat 110, and the locking member 200 is assembled in the fixing seat 110, and the vascular dressing 300 is clamped between the fixing member 100 and the locking member 200. Thus, the fixing member 100 is connected with the vascular dressing 300 to define the gap between the vascular dressing and the abnormal blood vessel, and the growth space of the abnormal blood vessel is limited and it no longer expands, for example, protruding from the epidermis.

[0045] A fixing cavity 130 is arranged along the axial direction of the fixing seat 100, and a fixing groove 131 is also arranged on the inner wall of the fixing cavity 130 for accommodating a vascular dressing, thereby enhancing the "grabbing" ability of the fixing cavity 130 for the vascular dressing placed therein and preventing it from falling out, thereby facilitating a more secure connection between the vascular dressing 300 and the fixing member 100.

[0046] The fixing cavity 130 further includes a receiving area 132 and a buckle pin area 133. The receiving area 132 is used to accommodate the main body of the locking member 300, and the buckle pin area 133 is used to form a stable connection between the locking member 200 and the fixing member 100. In this embodiment, along the direction in which the locking member 200 is placed into the fixing cavity 130, the receiving area 132 is located in the front, and the buckle pin area 133 is located in the back. That is, as shown in the figure, the locking member 200 is placed into the fixing cavity 130 from top to bottom, and the receiving area 132 is located above the buckle pin area 133.

[0047] The locking member 200 includes an assembly force-applying end 210 and a locking end 230. The locking end 230 is located at the leading end in the direction in which the locking member is placed into the fixing cavity, and is assembled with the buckle pin area 133. That is, as shown in the figure, the locking member 200 is placed into the fixing cavity 130 from top to bottom, and the locking end 230 is at the bottom, and the assembly force-applying end 210 is at the top. In this way, the locking member 200 and the fixing member 100 are tightly and firmly connected. At the same time, the vascular dressing 300 arranged between the locking member 200 and the fixing member 100 is also firmly placed in the fixing cavity 130, and it is difficult to easily fall out, so that the malformed blood vessel area and area covered by the vascular dressing 300 can be maintained.

[0048] The assembly force-applying end 210 is a functional end provided for the purpose of assembly and for the convenience of applying external force. It does not necessarily have a spatial entity, for example, a hexagonal cavity 240, which can also be connected with a force-applying tool to achieve the purpose of assembling the locking member 200 and the fixing cavity 130. No matter what shape the assembly force-applying end 210 adopts, it only needs to be connected with a force-applying tool that matches it to achieve the purpose of assembling the locking member 200 and the fixing cavity 130, and this part can be used as the assembly force-applying end 210.

[0049] A locking key 231 is provided on the locking end 230 to make the connection between the locking member 200 and the fixing member 100 tighter and more stable. The locking key 231 moves in the buckle pin area 133, and the locking key 231 contacts or disengages from the inner wall of the buckle pin area 133, thereby realizing the connection and separation between the locking member and the fixing member. In this embodiment, after the locking member 200 is placed in the fixing cavity 130, a torsional force is applied to the assembly force application end 210, driving the locking key 231 to rotate (clockwise in the figure), enter the buckle pin area 133, and come into surface contact with the inner wall of the buckle pin area, thereby realizing the connection between the locking member 200 and the fixing member 100 (see for details). Figure 2). Then, a torsional force is applied to the assembly force application end 210, driving the locking key 231 in the buckle pin area to rotate (counterclockwise in the figure), and the contact surface with the inner wall of the buckle pin area is separated, and the locking key 231 is disengaged from the buckle pin area 133, realizing the separation of the locking member 200 and the fixing member 100 (see Figure 3 ). Subsequently, the locking member 200 can be taken out from the fixing cavity 130. At this time, the vascular dressing 300 arranged between the locking member 200 and the fixing member 100 is also taken out from the fixing cavity 130, which is conducive to adjusting the malformed blood vessel region and area covered by the vascular dressing 300.

[0050] The locking surface 232 provided on the locking key 231 is arranged to face the assembly force-applying end 210. When a torsional force is applied to the assembly force-applying end 210, the locking key 231 is driven to rotate, and the locking surface 232 is tilted to the radial direction of the locking member, thereby enhancing the connection between the locking member 200 and the fixing member 100 to be tighter and more stable. The radial angle (not shown) between the locking surface 232 and the locking member is greater than 0° and less than or equal to 45°, or greater than 0° and less than or equal to 35°, or greater than 0° and less than or equal to 25°, or greater than 0° and less than or equal to 15°, or greater than 0° and less than or equal to 10°.

[0051] The locking member 200 further includes an assembly flap 220, one end of which is connected to the assembly force-applying end 210, and the other end is connected to the locking end 230. When the locking end 230 is arranged at one end of the assembly flap 220, it is also regarded as a part of the assembly flap 220. The assembly force-applying end 210 does not necessarily have a spatial entity, so one end of the assembly flap 220 also forms the assembly force-applying end 210. For example, a plurality of assembly flaps 220 are enclosed to form a polyhedron such as a triangular prism, a quadrangular prism or a hexagonal prism, and are connected by a force-applying tool matched therewith, so that a force can be applied to the locking member 200 as a whole, so that the locking member 200 moves, such as rotating or moving linearly.

[0052] The interior enclosed by a plurality of assembly petals 220 forms a travel space, which provides the required space for the assembly petals to move radially (for example, displacement due to elastic deformation), thereby helping to enhance the locking effect between the locking end and the buckle area to form a tighter and more stable connection.

[0053] The gaps 221 are provided between the assembly flaps 220, which not only facilitates the accommodating of the vascular dressing 300 therein, but also enhances the "grabbing" capability of the fixing cavity 130 for the vascular dressing therein, prevents it from slipping out, and facilitates a more secure connection between the vascular dressing 300 and the fixing member 100. It also facilitates the radial displacement of the assembly flap (for example, displacement due to elastic deformation) to provide the required space, thereby facilitating the enhanced locking effect between the locking end and the buckle pin area, and forming a tighter and more stable connection.

[0054] Figure 8 The photo of an embodiment of inserting the kit of this embodiment into the subcutaneous part of the inner arm of a patient with vascular malformation shows that after the vascular dressing 300 is covered on the affected part of the vascular malformation, the vascular dressing 300 is assembled and fixed using a fixing piece (not shown) and a locking piece 200, and the fixing piece is inserted into the bone tissue. Fig. 9 This is a photo of the suture after surgery. As a result, the growth space of the malformed blood vessels is limited and no longer expands, for example, protruding from the epidermis. Among 10 patients, the kit of this embodiment was implanted under the skin on the inner side of the arm of patients with vascular malformations. After clinical follow-up, 9 patients have shown significant improvement, with an improvement rate of 90% or more.

[0055] It has been verified that the kit of this embodiment is applied to the treatment of vascular malformations, so that the space for the expansion of vascular malformations is reduced or suppressed, and no longer protrudes on the epidermis, effectively reducing the occurrence of fascial hernia and periosteal hernia. For the treatment of diffuse vascular malformations, since the space for the expansion of vascular malformations is reduced or suppressed, the further expansion of the abnormal blood vessels is limited, which not only improves the efficiency of treatment, but also reduces the number of interventional sclerosis treatments required, and even achieves the closure of abnormal blood vessels, reducing the necessity of subsequent surgery.
