DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The present application discloses a micro-bone fracture plate, specifically, Figures 1 to 5 As shown, the micro-bone fragment plate includes a main plate 1, an auxiliary plate 2, a micro-bone fragment grasping hook 3 and a micro-bone fragment blocking block 4. The main plate 1 is provided with a middle fixing hole 7, a sliding hole 8 and a proximal fixing hole 9 in sequence from the first end of the main plate 1 to the second end of the main plate 1. The auxiliary plate 2 is connected to the first end of the main plate 1. Fenders are provided on both sides of the auxiliary plate 2. Distal fixing holes 10 are opened on the fenders. The micro-bone fragment grasping hook 3 is provided on the fenders. The micro-bone fragment blocking block 4 is extended outward from the non-connected end of the auxiliary plate 2. The micro-bone fragment blocking block 4 is located between the fenders on both sides. The bone plate of the embodiment of the present application can be based on the small bone fragment blocking block 4 and the small bone fragment grasping hook 3 to assist in the repositioning and grasping of the distal free small bone fragments before surgery, and the sliding hole 8 can be used to assist in the position fixation stability of the small bone fragments after repositioning, thereby improving the fixation effect of the distal small bone fragments.

[0024] In an operative solution, the bone plate auxiliary plate 2 is integrally formed with the bone plate main plate 1. Preferably, the micro-bone plate can be made of metal materials, such as pure titanium, titanium alloy (such as Ti6Al4V ELI), stainless steel, etc. These materials have good biocompatibility and mechanical strength. It can also be made of polymer materials. It can also be made of nano-hydroxyapatite / polylactic acid composite materials. It is understandable that the nano-hydroxyapatite / polylactic acid composite material is biodegradable and can promote bone tissue growth.

[0025] In one example, the bone plate auxiliary plate 2 and the bone plate main plate 1 can be integrally formed by hot die forging.

[0026] Further, the fender includes a first fender 5 and a second fender 6, the first fender 5 is connected to the main plate 1 with a first distal bending portion 11, the second fender 6 is connected to the main plate 1 with a second distal bending portion 12, and a middle bending portion 13 is formed between the auxiliary plate 2 and the main plate 1. In one example, as Figure 4 As shown, the first distal bending portion 11 may be a groove structure, the second distal bending portion 12 may be a groove structure, and the middle bending portion 13 may be a groove structure. By providing a groove structure at the connection between the fender and the main plate 1 of the bone fracture plate and providing a groove structure between the auxiliary plate 2 and the main plate 1 of the bone fracture plate, the mutual bending between the fender and the main plate 1 of the bone fracture plate and the mutual bending between the main plate 1 of the bone fracture plate and the auxiliary plate 2 of the bone fracture plate are facilitated, thereby meeting the bending and shaping requirements of the micro-bone fracture plate.

[0027] Further, the micro-bone fragment plate of the present application can be applied to distal fractures of the metacarpal bone or the medial and lateral malleolus, and can also be applied to simple distal fractures of the radius. Exemplarily, when the micro-bone fragment plate is applied to distal fractures of the metacarpal bone or the medial and lateral malleolus, the first distal bending portion 11, the second distal bending portion 12, and the middle bending portion 13 can be pre-bent and shaped before surgery to reset the distal free micro-bone fragments. After the distal free micro-bone fragments are reset, the free micro-bone fragments are grasped with the micro-bone fragment grasping hook 3, and appropriate pressure is applied through the sliding hole 8, and then a locking screw of a suitable length is inserted through the distal fixing hole 10 and the proximal fixing hole 9 to fix it. Further, when the micro-bone fragment plate is applied to simple distal fractures of the radius, the middle bending portion 13 can be pre-bent and shaped before surgery. The free tiny bone fragments are grasped by the tiny bone fragment grasping hook 3, and appropriate pressure is applied through the sliding hole 8, and then a locking screw of appropriate length is inserted and fixed through the distal fixing hole 10 and the proximal fixing hole 9. When the above is applied at different distal ends, the pre-bending and shaping of each bending part facilitates the reduction of the distal free tiny bone fragments, and based on the interaction between the tiny bone fragment grasping hook 3 and the tiny bone fragment blocking block 4, the free tiny bone fragments are effectively grasped and reduced.

[0028] Furthermore, in another feasible scheme, the first distal bend 11 can also be a discontinuous line, that is, the first fender 5 and the main plate 1 are connected by a discontinuous line, and the second distal bend can also be a discontinuous line, that is, the second fender 6 and the main plate 1 are connected by a discontinuous line.

[0029] In an implementable solution, the middle bending portion 13 may also be a discontinuous line, that is, the bone plate auxiliary plate 2 and the bone plate main plate 1 are connected by a discontinuous line.

[0030] It can be understood that constructing each bending portion as a groove structure or as a discontinuous line is only a preferred embodiment. In other feasible schemes, each bending portion can also be constructed as other structures that can achieve pre-bending, or each bending portion can be a combination of a groove structure and a discontinuous line. The specific setting can be based on needs and is not specifically limited here.

[0031] Furthermore, the first fender 5 is provided with at least one of the tiny bone fragment grasping hooks 3 , and the second fender 6 is provided with at least one of the tiny bone fragment grasping hooks 3 .

[0032] Furthermore, the tiny bone fragment grasping hook 3 includes a hook claw portion 31 and a connecting portion 32 , one end of the connecting portion 32 is connected to the fender, and the other end of the connecting portion 32 is connected to the hook claw portion 31 , and the hook claw portion 31 is located on the end side of the connecting portion 32 .

[0033] In an implementable solution, the fender includes a sheet metal surface and a sheet metal extension surface extending from the side of the sheet metal surface in a direction away from the sheet metal surface, the sheet metal extension surface and the side of the main plate 1 of the bone fracture plate have a smooth transition, and the distal fixing hole 10 penetrates the thickness of the fender from the sheet metal surface. That is, in the embodiment of the present application, the fender is constructed based on the sheet metal structure. It can be understood that the sheet metal structure can reduce the thickness of the fender, and reduce the bending force when the first distal bending portion 11 and the second distal bending portion 12 need to be pre-bent.

[0034] The micro-bone fragment bone fracture plate of the present application comprises a bone fracture plate main plate 1, a bone fracture plate auxiliary plate 2, a micro-bone fragment grasping hook 3 and a micro-bone fragment blocking block 4. The bone fracture plate main plate 1 is provided with a middle fixing hole 7, a sliding hole 8 and a proximal fixing hole 9 in sequence from the first end of the bone fracture plate main plate 1 to the second end of the bone fracture plate main plate 1. The bone fracture plate auxiliary plate 2 is connected to the first end of the bone fracture plate main plate 1. Fenders are provided on both sides of the bone fracture plate auxiliary plate 2. A distal fixing hole 10 is provided on the fenders. The micro-bone fragment grasping hook 3 is provided on the fenders. The micro-bone fragment blocking block 4 is extended outward from the non-connected end of the bone fracture plate auxiliary plate 2. The micro-bone fragment blocking block 4 is located between the fenders on both sides. The present application can be based on the micro-bone fragment blocking block 4 and the micro-bone fragment grasping hook 3 to assist in the resetting and grasping of the distal free micro-bone fragments before surgery, and the position fixation stability of the small bone fragments after the resetting is assisted by the sliding hole 8, so as to improve the fixation effect of the distal small bone fragments.

[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
