Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical devices, in particular to an external fixation traction device for trauma orthopedics. Background Art
[0002] At present, traumatic fractures and bone nonunion, delayed bone union, and bone deformity caused by various factors are seriously threatening human health, and greatly affecting the living standards and quality of life of disabled people. In the process of fracture treatment, reduction and fixation are crucial links. Good reduction operation can create favorable conditions for fracture healing and limb function recovery. Orthopedic external fixator is a treatment method to assist in fracture reduction. Its specific operation is to accurately insert Kirschner wires at the distal and proximal ends of the fracture site, and then use the needle holder to tightly connect and firmly fix the Kirschner wires to the external frame body, so as to achieve external fixation and flexible adjustment of the fracture site. The significant advantage of the treatment method is that the surgery has little trauma, which can not only avoid disrupting local blood circulation to the greatest extent, but also provide a stable fixation effect for the fracture site. Since patients usually wear external fixators for more than three months, and the current Kirschner wires penetrate the skin and bones, although the Kirschner wires can play a good fixation role on the bones, there is a lack of corresponding protection measures for the parts that come into contact with the skin. When patients are doing walking exercises, the outer skin will be pulled by the Kirschner wires, which can easily lead to inflammatory reactions in the skin at the puncture site and even infection. Therefore, it is necessary to take protective measures for the skin tissue around the Kirschner wires when patients are doing walking exercises. Summary of the Invention
[0003] The present invention provides an external fixation traction device for trauma orthopedics. By arranging a compression component that can be installed at any position on the Kirschner wire, auxiliary pressing and fixation can be performed on the skin around the Kirschner wire puncture site. In this way, the patient's skin can be effectively prevented from being pulled by the Kirschner wire when walking, and the risk of inflammation and infection at the skin puncture site is greatly reduced, so as to solve the problem of insufficient protection at the contact point between the existing Kirschner wire and the skin, which causes the patient's skin to be pulled when walking and exercising.
[0004] In order to solve the above technical problems, the present invention provides the following technical solutions:
[0005] An external fixation and traction device for trauma orthopedics comprises at least two fixing rings, each of which is provided with a constraint groove; a connecting rod is installed between the fixing rings and inside the constraint groove; a needle seat is fixedly connected to the outer side of the connecting rod, and a Kirschner wire is slidably connected to the inside of the needle seat; a compression assembly is used to compress and fix the skin tissue around the Kirschner wire puncture site, and the compression assembly is connected to the Kirschner wire.
[0006] Optionally, the compression assembly includes a first clamp sleeve and a second clamp sleeve installed on the outside of the Kirschner wire, and two extension arms are symmetrically installed on the first clamp sleeve and the second clamp sleeve. An elastic plate is installed on one side of the extension arms, and a gauze pad is installed on the side of the elastic plate away from the extension arm.
[0007] Optionally, the first clamping sleeve includes two first clamping seats, two first connecting arms are symmetrically fixedly connected between the two first clamping seats, and a plurality of hooks are symmetrically fixedly connected to the outside of the first connecting arms.
[0008] Optionally, the second clamp sleeve includes two second clamp seats, two second connecting arms are symmetrically fixedly connected between the two second clamp seats, and a plurality of through holes for plugging hooks are symmetrically opened inside the second clamp seats.
[0009] Optionally, a first clamping protrusion is fixedly connected to one side of the first connecting arm, a second clamping groove is provided inside the second connecting arm, and the first clamping protrusion extends into the second clamping groove, a second clamping protrusion is provided on the outside of the second connecting arm, a first clamping groove is provided inside the first connecting arm, and the second clamping protrusion extends into the first clamping groove.
[0010] Optionally, the exterior of the two first connecting arms is provided with an outward-turning portion.
[0011] Optionally, two insertion holes are provided inside each of the extension arms, and a plurality of insertion posts are fixedly connected to the side of the elastic plate away from the gauze pad, and the insertion posts are inserted into the insertion holes.
[0012] Optionally, an elastic sheet is provided on the side of the extension arm close to the elastic plate, a weakened bending portion is provided at the connection between the elastic sheet and the extension arm, an adjusting bolt is threadedly connected to the inside of the extension arm, and one end of the adjusting bolt is in conflict with the side of the elastic sheet away from the elastic plate.
[0013] Optionally, two bandages are symmetrically arranged on one side of the gauze pad, and the bandages are sleeved on the outside of the elastic plate.
[0014] Optionally, an open channel for passing the Kirschner wire is opened inside the elastic plate, and a plurality of through grooves are symmetrically opened inside the elastic plate.
[0015] Compared with the prior art, the present invention has at least the following beneficial effects:
[0016] In the above scheme, the external fixation traction device for trauma orthopedics can not only achieve stable fixation of Kirschner wires in different positions with the help of the coordinated action of multiple connecting rods and needle holders, but also has the function of flexibly adding a compression component at any position outside the Kirschner wire. Through this design, the skin around the Kirschner wire puncture site can be auxiliary pressed and fixed, effectively preventing the patient's skin from being pulled by the Kirschner wire when walking, thereby significantly reducing the risk of inflammation and infection at the skin puncture site.
[0017] The hook on the first clip seat can be accurately inserted into the perforation inside the second clip seat to achieve pre-fixation of the first clip sleeve and the second clip sleeve on the Kirschner wire. Based on this, the position of the compression component on the Kirschner wire can be flexibly adjusted to ensure that the gauze pad is accurately pressed on the skin puncture site. Subsequently, the first clip protrusion on the first connecting arm and the second clip groove on the second connecting arm, as well as the second clip protrusion on the second connecting arm and the first clip groove on the first connecting arm are tightly engaged, so that the first clip sleeve and the second clip sleeve can be firmly locked on the Kirschner wire, completing the fixation of the compression component, thereby achieving auxiliary fixation of the skin, and effectively reducing the discomfort of the skin caused by the traction of the Kirschner wire during walking.
[0018] Multiple extension arms are designed with a certain degree of curvature. This unique design can promote the natural curvature of the elastic plate, significantly improving its fit with the legs. At the same time, through the coordinated action of the adjustment bolt at the front end of the extension arm and the elastic sheet, the edges and corners of the elastic plate can be compressed for the second time to ensure that the elastic plate fits closely with the skin, thereby ensuring that the gauze pad on the outside of the elastic plate produces a stable and effective compression effect on the skin.

[0037] like Figures 1 to 9As shown, an embodiment of the present invention provides an external fixation traction device for trauma orthopedics, comprising at least two fixing rings 1, each of which is provided with a constraint groove, and a connecting rod 2 is installed between the fixing rings 1 and inside the constraint groove. The constraint groove is set through the inside of the fixing ring 1. This setting can replace the traditional punching method, which not only has a good lightweight effect, but also can realize the adjustment of the connecting rod 2 to any position, and can more flexibly adapt to the puncture position. The connecting rod 2 can select the corresponding length specification according to the use requirements to meet the installation between two or more fixing rings 1. The external thread of the connecting rod 2 is connected with multiple nuts, and the fixing ring 1 is pressed against the multiple nuts, which can conveniently fix the position of the connecting rod 2 and ensure the stability of the external fixator outside the patient's body. The outer side of the connecting rod 2 is fixedly connected to the needle seat 3, and the inside of the needle seat 3 is slidably connected to the Kirschner wire 4. The needle seat 3 has a multi-angle adjustment feature. This function not only enables it to flexibly adjust the angle of the Kirschner wire 4, but also can change its installation angle on the connecting rod 2, so as to better adapt to diverse puncture needs; the compression component, the compression component is used to compress and fix the skin tissue around the puncture site of the Kirschner wire 4. The compression component is connected to the Kirschner wire 4. The compression component can be installed at any position of the Kirschner wire 4, and the angle after installation can be adjusted to fit the skin, thereby achieving auxiliary pressing and fixation of the skin around the puncture site of the Kirschner wire 4, effectively preventing the patient's skin from being pulled by the Kirschner wire 4 when walking, and greatly reducing the risk of inflammation and infection at the skin puncture site.
[0038] like Figure 3 、 Figure 4 and Figure 7As shown, the compression assembly includes a first clamping sleeve 5 and a second clamping sleeve 6 installed on the outside of the Kirschner wire 4, and two extension arms 7 are symmetrically installed on the first clamping sleeve 5 and the second clamping sleeve 6. An elastic plate 8 is installed on one side of the multiple extension arms 7, and the extension arm 7 has a movable forward curvature. This design can make the elastic plate 8 installed on the extension arm 7 have a curvature that fits the leg, which can improve the adaptation effect of the elastic plate 8 and the leg. Two sockets 701 are provided inside each extension arm 7, and a plurality of plug posts 801 are fixedly connected to the side of the elastic plate 8 away from the gauze pad 9, and the plug posts 801 are inserted into the inside of the sockets 701. The diameter of the plug posts 801 is slightly larger than the aperture of the socket 701. This design can improve the stability of the connection between the elastic plate 8 and the extension arm 7, and the elastic plate 8 has a useful In order to pass through the open channel of the Kirschner wire 4, a plurality of through grooves are symmetrically provided inside the elastic plate 8. The open channel on the elastic plate 8 can be conveniently inserted into the outside of the Kirschner wire 4, and then connected to the extension arm 7. The through grooves provided on the extension arm 7 can not only achieve the lightweight of the extension arm 7, but also improve the heat dissipation effect after compression. A gauze pad 9 is installed on the side of the elastic plate 8 away from the extension arm 7. A through gap is provided in the gauze pad 9, which can be conveniently put on the outside of the Kirschner wire 4. Two bandages 901 are symmetrically provided on one side of the gauze pad 9, and the bandage 901 is put on the outside of the elastic plate 8. The use of the gauze pad 9 can not only achieve compression of the puncture site, but also has a breathable effect, which can keep the wound dry. The bandage 901 can facilitate the installation of the gauze pad 9 on the elastic plate 8, which is convenient for replacing it.
[0039] like Figures 4 to 8 As shown, the first clamp sleeve 5 includes two first clamp seats 501, two first connecting arms 502 are symmetrically fixedly connected between the two first clamp seats 501, and multiple hooks 503 are symmetrically fixedly connected to the outside of the first connecting arms 502. The second clamp sleeve 6 includes two second clamp seats 601, two second connecting arms 603 are symmetrically fixedly connected between the two second clamp seats 601, and multiple through-holes 602 for plugging the hooks 503 are symmetrically opened inside the second clamp seat 601. When the first clamp sleeve 5 and the second clamp sleeve 6 are docked, the hooks 503 can pass through the through-holes 602 and be buckled on the second clamp seat 601, thereby fixing the first clamp sleeve 5 and the second clamp sleeve 6. At this time, the combined first clamp sleeve 5 and the second clamp sleeve 6 can slide on the outside of the Kirschner wire 4, thereby adjusting the position of the compression component on the Kirschner wire 4 to ensure that the gauze pad 9 is accurately pressed on the skin puncture site.
[0040] A first clamping protrusion 504 is fixedly connected to one side of the first connecting arm 502, a second clamping groove 604 is provided inside the second connecting arm 603, and the first clamping protrusion 504 extends into the second clamping groove 604, and a second clamping protrusion 605 is provided on the outside of the second connecting arm 603. The first clamping groove 505 is clamped inside the first connecting arm 502, and the second clamping protrusion 605 extends into the first clamping groove 505. When the first clamping sleeve 5 and the second clamping sleeve 6 are docked, the first clamping protrusion 504 is accurately embedded in the second clamping groove 604. At the same time, the second clamping protrusion 605 is also correspondingly clamped into the first clamping groove 505, thereby promoting a tight engagement between the first connecting arm 502 and the second connecting arm 603. During the process of pressing the clamp, the first clamp sleeve 5 and the second clamp sleeve 6 will be gradually tightened, and finally after the first connecting arm 502 and the second connecting arm 603 are fully engaged, the compression component is fixed, and the gauze pad 9 on the compression component is pressed and fixed to the skin, which can effectively reduce the discomfort of the skin caused by the traction of the Kirschner wire 4 when walking. The outside of the two first connecting arms 502 is provided with an outward-turning portion 506, and the outward-turning portion 506 is turned outward to form a space for fingers to be placed, so that when the first clamp sleeve 5 and the second clamp sleeve 6 are disassembled, it is convenient to put the fingers into the first connecting arm 502 to separate it from the second connecting arm 603. The extension arm 7 is respectively fixed on the first clamp seat 501 and the second clamp seat 601. The extension arm 7 is integrally injection-molded with the first clamp sleeve 5 or the second clamp sleeve 6, which can ensure the overall structural strength and the stability of the leg compression.
[0041] like Figure 7 and Figure 9 As shown, an elastic sheet 702 is provided on the side of the extension arm 7 close to the elastic plate 8, and a weakened bending portion 703 is provided at the connection between the elastic sheet 702 and the extension arm 7. An adjusting bolt 704 is threadedly connected to the internal thread of the extension arm 7, and one end of the adjusting bolt 704 is in conflict with the side of the elastic sheet 702 away from the elastic plate 8. Since a weakened bending portion 703 is provided between the elastic sheet 702 and the extension arm 7, when the elastic sheet 702 is pressurized, it will rotate along the weakened bending portion 703. Through the adjusting bolt 704 at the front end of the extension arm 7 and the squeezing of the elastic sheet 702, secondary compression can be achieved on the corners of the elastic plate 8 to ensure that the elastic plate 8 fits tightly against the skin.
[0042] The workflow of the technical solution provided by the present invention is as follows:
[0043] Place the fixing ring 1 on the proximal and distal ends of the limb fracture site respectively, select the puncture points at the proximal and distal ends of the fracture, and use a bone drill to insert the Kirschner wire 4 into the bone through the skin and subcutaneous soft tissue, and ensure that the Kirschner wire is at a specific angle to the long axis of the backbone until it penetrates the skin on the opposite side. Then adjust the penetration depth of the Kirschner wire 4, and install the needle seat 3 at both ends. Insert the connecting rod 2 into the preset constraint groove inside the fixing ring 1, turn the nut on the outside of the connecting rod 2 to fix the connecting rod 2 and the fixing ring 1, assemble the Kirschner wire 4 with the needle seat 3 installed with the connecting rod 2, and finally, tighten the fixing knob on the needle seat 3 to ensure a firm connection between the Kirschner wire 4, the needle seat 3 and the connecting rod 2.
[0044] When the patient is walking and exercising, the first clamping sleeve 5 and the second clamping sleeve 6 are clamped on both sides of the Kirschner wire 4 from two directions. At this time, the hook 503 on the first clamping seat 501 passes through the perforation 602 and is connected to the first clamping seat 501 to realize the pre-fixation of the first clamping sleeve 5 and the second clamping sleeve 6, and then the elastic plate 8 is clamped on the outside of the Kirschner wire 4, and the elastic plate 8 is pushed to move so that the plug 801 is inserted into the socket 701 inside the extension arm 7 to realize the assembly of the extension arm 7 and the elastic plate 8. Then, the gauze pad 9 is clamped on the outside of the Kirschner wire 4 and the gauze pad 9 is installed on one side of the elastic plate 8 through the bandage 901. After the compression component is assembled, it is pushed to slide or rotate on the outside of the Kirschner wire 4 to adjust its position and angle until the gauze pad 9 is tightly pressed against the periphery of the puncture site, and then the first connecting arms 502 on both sides of the first clamping sleeve 5 are pressed so that the first connecting arms 502 on the first connecting arms 502 are pressed. The clamping protrusion 504 is clamped into the second clamping groove 604 on the second clamping sleeve 6. At the same time, the second clamping protrusion 605 on the second clamping sleeve 6 is clamped into the first clamping groove 505, thereby forming an occlusal fixation of the first connecting arm 502 and the second connecting arm 603. At this time, the compression assembly can be fixed to the Kirschner wire 4. Observe the degree of fit between the corners of the elastic plate 8 and the gauze pad 9 and the skin. If there is a gap, rotate the adjusting bolt 704 on the corresponding extension arm 7. At this time, the adjusting bolt 704 drives the elastic plate 702 to rotate along the weakened bending portion 703, thereby achieving secondary extrusion of the elastic plate 8 and the gauze pad 9, and then eliminating the gap with the skin, ensuring that the compression assembly is completely fitted to the skin. Since the gauze pad 9 has good air permeability and a plurality of through grooves are provided on the elastic plate 8, it can also assist in heat dissipation, thereby ensuring that the skin at the compression point is dry.
[0045] After the walking exercise, insert your finger into the gap of the eversion part 506 and move the first connecting arm 502 to separate the first connecting arm 502 from the second connecting arm 603. At this time, you can push the compression assembly to slide on the Kirschner wire 4 again, thereby separating the gauze pad 9 from the skin. After the movement is completed, the compression assembly can be fixed on the Kirschner wire 4 again through the first connecting arm 502 and the second connecting arm 603 to facilitate subsequent use. You can also separate the first clamping sleeve 5 from the second clamping sleeve 6 to complete the removal of the compression assembly, thereby improving the flexibility of the use of the compression assembly.
[0046] The present invention encompasses any alternatives, modifications, equivalents, and solutions that fall within the spirit and scope of the present invention. While specific details are described in detail in the preferred embodiments to provide a thorough understanding of the present invention, those skilled in the art will be able to fully understand the present invention without these details. Furthermore, to avoid unnecessary confusion regarding the essence of the present invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.
[0047] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
