Description

Technical Field

[0001] This utility model relates to the field of veterinary medical device technology, and in particular to an external fixation bracket and fixation system for long bone fractures in animals. Background Technology

[0002] Bone plates are generally not suitable for fixing long bone fractures in small animals because the cortex of long bones in small animals is thin, making it difficult to provide sufficient support for bone screws. At the same time, using bone plates will cause more damage to the soft tissue outside the bone, which will greatly slow down the bone tissue recovery. Therefore, when treating long bone fractures in these animals, Kirschner wires are often used in conjunction with external fixation devices to fix the bone and achieve the treatment goal.

[0003] Kirschner wire external fixators can be classified into Type I, Type II, and Type III. Type I provides unilateral fixation, Type II provides bilateral fixation, and Type III provides multilateral fixation. Type I external fixators cannot provide multidimensional fixation at the fracture site, resulting in poor fixation effectiveness. Type II and Type III external fixators can provide multilateral support at the fracture site; however, because animals cannot undergo prolonged bed rest like humans, multilateral support at the fracture site is difficult to apply to fracture treatment in small animals. Utility Model Content

Both the inner side and the outer side are arc-shaped and are spaced apart. Along the length of the support body, the first surface and the second surface are located at the two ends of the inner side and the outer side, respectively; The first surface is provided with injection holes for injecting adhesive. There are at least two injection holes, which are spaced apart circumferentially along the first surface. Each injection hole penetrates both the first surface and the second surface. The inner side is provided with mounting holes for mounting Kirschner wires. The mounting holes pass through the inner side and the outer side. There are multiple mounting holes. Each injection hole has a row of mounting holes on its axis. The center of each mounting hole intersects with the axis of the injection hole.

[0028] The following is combined Figures 1 to 5 The present invention will provide a detailed description of the external fixation bracket and fixation system for animal long bone fractures provided by the present invention through specific embodiments and application scenarios.

[0029] Firstly, such as Figure 1 As shown, this embodiment provides an external fixation bracket 1 for animal long bone fractures, including: a bracket body.

[0030] The support body has an inner side 11, an outer side 12, a first surface 13, and a second surface 14.

[0031] The inner side 11 is used to face the outer side of the long bone. Both the inner side 11 and the outer side 12 are set with arc surfaces, and the inner side 11 and the outer side 12 are set at intervals.

[0032] Along the length of the support body, the first surface 13 and the second surface 14 are located at the two ends of the inner side 11 and the outer side 12, respectively.

[0033] The first surface 13 is provided with injection holes 131 for injecting adhesive. There are at least two injection holes 131, which are arranged at intervals along the circumference of the first surface 13. Each injection hole 131 penetrates the first surface 13 and the second surface 14.

[0034] The inner side 11 is provided with mounting holes 111 for mounting Kirschner wires 2. The mounting holes 111 pass through the inner side 11 and the outer side 12. There are multiple mounting holes 111. Each injection hole 131 has a row of mounting holes 111 on its axis. The center of each mounting hole 111 intersects the axis of the injection hole 131.

[0035] Among them, the projected area of ​​the injection hole 131 at any cross section between the inner side 11 and the outer side 12 is greater than the projected area of ​​the mounting hole 111 at that cross section.

[0036] Understandably, for small animals weighing less than 10kg, such as kittens, puppies, rabbits, guinea pigs, and chinchillas, the skin layer of their long bones is thin, making it impossible to use bone plates and screws for fixation. Furthermore, the active nature of small animals makes it unsuitable to use a full-circle external fixator.

[0037] The external fixator 1 in this embodiment includes a support body. The support body has a seat structure, with the inner side 11 facing the outer side of the long bone. Since both the inner side 11 and the outer side 12 are arc-shaped surfaces, the first surface 13 and the second surface 14 located at both ends of the inner side 11 and the outer side 12 are annular surfaces. The inner side 11 and the outer side 12 are arranged in parallel and are connected to two side surfaces 15 from both sides respectively. The arc-shaped surface structure of the inner side 11 can better conform to the outer side of the animal's long bone and play a role in fixing the fracture site of the long bone.

[0038] In addition to supporting and fixing the fracture site of the long bone, the support body can also accommodate Kirschner wires 2. Mounting holes 111 are used to mount the Kirschner wires 2. This embodiment has multiple mounting holes 111 to accommodate multiple Kirschner wires 2 when fixing the long bone fracture site. Because the fracture sites differ, the Kirschner wires 2 need to be mounted on the support body in different positions; therefore, the diameter of the mounting holes 111 must be larger than the diameter of the Kirschner wires 2. The shape of the mounting holes 111 can be various, as long as it allows for adjustment of the insertion angle of the Kirschner wires 2.

[0039] To secure the Kirschner wires 2 inserted into the support body, an injection hole 131 is provided on the first surface 13, penetrating both the first and second surfaces 14. Furthermore, the axis of the injection hole 131 intersects the center of each mounting hole 111, so that the Kirschner wires 2 inserted into the mounting holes 111 are exposed within the injection hole 131, and the adhesive injected through the injection hole 131 bonds the Kirschner wires 2 to the support body. To further secure the support body to one side of the long bone, this embodiment provides at least two injection holes 131, allowing for the installation of Kirschner wires 2 within at least two rows of mounting holes 111. Each row contains multiple mounting holes 111, allowing the Kirschner wires 2 to be adjusted in position along the height direction of the support body, and enabling the installation of multiple Kirschner wires 2 along the height direction of the support body. Each row contains at least three mounting holes 111.

[0040] Specifically, this embodiment provides three injection holes 131, and each injection hole 131 corresponds to a row of multiple mounting holes 111. The three injection holes 131 are evenly distributed along the annular surface of the first surface 13, so that the Kirschner wire 2 can be inserted around the outer side of the long bone to select the insertion position, better fit the outer side of the long bone for fixation, and achieve a better fixation effect.

[0041] Furthermore, in order to ensure the adhesive injection effect, the projection of the injection hole 131 on the cross section parallel to the inner side 11 and the outer side 12 in this embodiment is greater than the projection of the mounting hole 111 on the same cross section. That is, inside the bracket body, the outer edge of the injection hole 131 is larger than the diameter of the mounting hole 111, so that the adhesive injected from the injection hole 131 can cover the entire mounting hole 111, which is beneficial for fixing the Kirschner wire 2.

[0042] In practical applications, when treating fractures of long bones, Kirschner wires 2 are inserted through mounting holes 111. The fixation height and angle of Kirschner wires 2 are adjusted according to the specific fracture location, and adhesive is injected through injection holes 131. After the adhesive has solidified, the protruding Kirschner wires 2 are broken off, thus achieving fixation of the animal's long bone.

[0043] The external fixation bracket 1 for animal long bone fractures provided by this utility model has injection holes 131 on the first surface 13 of the bracket body and mounting holes 111 on the inner side 11. At least two injection holes 131 are provided, penetrating the first surface 13 and the second surface 14 and spaced apart circumferentially along the first surface 13. Furthermore, each row of mounting holes 111 is arranged sequentially along the axis of the injection holes 131, such that multiple mounting holes 111 are arrayed along the arc surface of the inner side 11. This allows the Kirschner wire 2 to be selectively inserted into the mounting holes 111 in each row of mounting holes 111. The installation height can be changed, and the installation angle can be changed by selecting the installation hole 111 in different columns of installation holes 111. Furthermore, the Kirschner wire 2 inserted into the installation hole 111 can also adjust the angle between itself and the support body along the height and width directions of the support body, realizing flexible adjustment of four degrees of freedom. Compared with the type iii external fixator 1, the external fixator 1 of this utility model does not need to be set around the entire outer side of the long bone to achieve the same multi-degree-of-freedom adjustment. It is smaller in size and does not affect the animal's daily activities, realizing unilateral and multi-dimensional stable fixation of the fracture site of the animal's long bone.

[0044] In this embodiment, the mounting hole 111 is polygonal.

[0045] Understandably, the mounting hole 111 can be polygonal, and the circular cross-section of the Kirschner wire 2 can rotate within the polygonal mounting hole 111 and adjust its orientation angle.

[0046] Alternatively, the polygon can be a regular polygon, such as a square, a regular hexagon, or a regular octagon.

[0047] In this embodiment, the mounting hole 111 is circular.

[0048] Understandably, when the mounting hole 111 is circular, the diameter of the mounting hole 111 is larger than the diameter of the Kirschner wire 2. In order to prevent the injected adhesive from rotating in the mounting hole 111, the entire injection hole 131 can be filled with adhesive so that the adhesive solidifies and forms a whole.

[0049] like Figure 1 As shown, the mounting hole 111 in this embodiment is a combination of multiple polygonal holes or multiple circular holes.

[0050] Multiple polygonal holes or multiple circular holes are arranged circumferentially along the center of mounting hole 111.

[0051] Understandably, in order to increase the range of angles that the Kirschner wire 2 can be adjusted along the mounting hole 111, the mounting hole 111 in this embodiment is a combination of multiple polygonal holes or multiple circular holes.

[0052] When adjusting the Kirschner wire 2 horizontally, it can be oriented towards a polygonal or circular hole on the horizontal plane. When adjusting the Kirschner wire 2 vertically, it can be oriented towards a polygonal or circular hole at that height. Alternatively, when adjusting the Kirschner wire 2 at any angle, it can be oriented towards any polygonal or circular hole in the circumferential direction, thus achieving flexibility in adjusting the angle of the Kirschner wire 2 and expanding the adjustment range.

[0053] Furthermore, when the mounting hole 111 is a combination of multiple polygonal holes or circular holes, in order to further reduce the weight of the external fixation bracket 1, adhesive can be injected only into the mounting hole 111 where the Kirschner wire 2 is installed. Since the adhesive in the mounting hole 111 cannot rotate around the mounting hole 111 after it solidifies, the Kirschner wire 2 can be stably fixed in the mounting hole 111, which further reduces the weight of the entire external fixation bracket 1.

[0054] like Figure 1 As shown, in this embodiment, the multiple polygonal holes or multiple circular holes are the same size, and the multiple polygonal holes or multiple circular holes are evenly arranged around the center of the mounting hole 111.

[0055] Understandably, multiple polygonal holes or multiple circular holes are of the same size and are evenly arranged around the center of the mounting hole 111, so that the Kirschner wires 2 can be adjusted at the same angle around the center of the mounting hole 111, which facilitates the operator's angle adjustment operation of the Kirschner wires 2.

[0056] like Figure 1 As shown, in this embodiment, the curvature of the first surface 13 is greater than or equal to the curvature of the second surface 14. The first surface 13 is disposed near the proximal end of the long bone, and the second surface 14 is disposed near the distal end of the long bone.

[0057] Understandably, because the proximal and distal outer contours of an animal's long bones differ in size, with the proximal end having a larger inner diameter than the distal end, the curvature of the first surface 13 in this embodiment is greater than the curvature of the second surface 14. The support body in this embodiment exhibits a shape that is wider at one end and narrower at the other, to better conform to the shape of the animal's long bones and achieve a better fixation effect.

[0058] like Figure 2 As shown, the curvature of the first surface 13 in this embodiment ranges from 10° to 180°.

[0059] Understandably, in order to fix the long bones of an animal on one side and avoid affecting the animal's daily activities, the curvature of the first surface 13 in this embodiment cannot exceed 180°. The curvature of the first surface 13 in this embodiment is α.

[0060] Specifically, the curvature of the first surface 13 can be 10°, 120°, or 180°, and is usually set between 60° and 120°.

[0061] like Figure 3 As shown, the curvature of the second surface 14 in this embodiment ranges from 10° to 180°.

[0062] Understandably, in order to fix the long bones of an animal unilaterally and avoid affecting the animal's daily activities, the curvature of the second surface 14 in this embodiment cannot exceed 180°. The curvature of the first surface 13 in this embodiment is β.

[0063] Specifically, the curvature of the second surface 14 can be 10°, 120°, or 180°, and is usually set between 60° and 120°.

[0064] like Figure 2 As shown, the radius of the arc formed by the first surface 13 and the outer side 12 in this embodiment ranges from 5 to 100 mm.

[0065] Understandably, the outer diameter of long bones varies for different small animals, and the radius of the arc formed by the first surface 13 and the outer side 12 in this embodiment can be adapted to the long bones of different small animals. The radius of the arc formed by the first surface 13 and the outer side 12 is r1.

[0066] Specifically, the radius of the arc formed by the first surface 13 and the outer edge 12 can be 5mm, 50mm, or 100mm.

[0067] like Figure 3 As shown, the radius of the arc formed by the second surface 14 and the outer edge 12 in this embodiment ranges from 5 to 105 mm.

[0068] Understandably, the outer diameter of long bones varies for different small animals, and the radius of the arc formed by the second surface 14 and the outer side 12 in this embodiment can be adapted to the long bones of different small animals. The radius of the arc formed by the second surface 14 and the outer side 12 is r2.

[0069] Specifically, the radius of the arc formed by the second surface 14 and the outer edge 12 can be 5mm, 50mm, or 105mm.

[0070] like Figure 1 As shown, the external fixation bracket 1 in this embodiment is made of titanium alloy, aluminum alloy, engineering plastic, nylon plastic, glass fiber, or carbon fiber plastic.

[0071] Understandably, in order to reduce the weight when fixing small animals, the external fixation bracket 1 in this embodiment uses lightweight components, such as titanium alloy components, aluminum alloy components, engineering plastic components, nylon plastic components, glass fiber components, or carbon fiber plastic components. The materials are lightweight yet strong, which can fix the fracture site of the animal's long bone without affecting the animal's daily activities.

[0072] Secondly, such as Figure 4 and Figure 5 As shown, this embodiment provides a fixation system, including: Kirschner wires 2, adhesive, and the above-mentioned external fixation bracket for animal long bone fractures 1.

[0073] At least one Kirschner wire 2 is provided. The Kirschner wire 2 passes through the mounting hole 111 and extends into the long bone. Adhesive is used to bond and fix the Kirschner wire 2 to the external fixation bracket 1.

[0074] Specifically, since the fixation system includes an external fixation bracket 1 for animal long bone fractures, and the specific structure of the external fixation bracket 1 for animal long bone fractures is as described in the above embodiments, the fixation system shown in this embodiment includes all the technical solutions of the above embodiments. Therefore, it has at least all the beneficial effects achieved by all the technical solutions of the above embodiments, which will not be described in detail here.

[0075] Understandably, the number of Kirschner wires 2 used for fixation varies depending on the specific location of the long bone spicules in different animals. One or multiple Kirschner wires 2 can be used, depending on the specific fixation scenario.

[0076] The fixation system can provide unilateral, multi-dimensional fixation at the bone pins of long bones in animals. It is lightweight and compact, does not affect the animal's daily activities, and achieves good therapeutic results.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
