Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to an electric intelligent external frame connection structure. Background Art

[0002] With the development of technology, orthopedic external fixators are becoming more and more electrified to improve the intelligence level of external fixators.

[0003] The host is an indispensable structure for the electrification of the external fixator. The fixing ring of the external fixator is provided with multiple holes for connection, and the host of the existing electric external fixator is fixed on the fixing ring through the holes. However, due to individual differences among patients and different fracture types, there are many specifications of external fixators, and the hole opening distances of the fixing rings of different specifications are different. As a result, when the host is set on external fixators of different specifications, it is necessary to use mounting structures of different specifications for fixation. This increases the cost of electrification of the external fixator, and also increases the learning and maintenance costs of the external fixator.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field. Summary of the invention

[0005] In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide an electric intelligent external frame connection structure to achieve universal installation of the electric external frame.

[0006] The technical solution of the present invention is as follows:

[0007] An electric intelligent external frame connection structure, used to connect the fixing ring of a Taylor frame and the main body shell. The electric intelligent external frame connection structure includes a first connecting piece, a second connecting piece and a fastener; the first connecting piece passes through the inner hole of the fixing ring, and the first connecting piece is connected to the main body shell; the second connecting piece passes through the outer hole of the fixing ring; the fastener simultaneously connects the first connecting piece and the second connecting piece; wherein the fastener and the main body shell are arranged on opposite sides of the fixing ring; the second connecting piece contacts the main body shell.

[0008] A further technical solution is that the first connecting member includes a connecting head and a first rod; the first rod passes through the inner hole; and the connecting head contacts the fixing ring and the main housing at the same time.

[0009] A further technical solution is that at least two first threaded holes are provided on the connecting head.

[0010] A further technical solution is that the second connecting member includes a supporting head and a second rod; the second rod passes through the outer hole; and the supporting head contacts the fixing ring and the main housing at the same time.

[0011] A further technical solution is that a flat position is provided on the second rod portion.

[0012] A further technical solution is that the fastener contacts the fixing ring.

[0013] A further technical solution is that the host housing is connected to the first connecting piece by screws.

[0014] A further technical solution is that the fastener is a bolt; a second threaded hole is respectively provided on the first connecting member and the second connecting member; the fastener simultaneously connects the second threaded holes on the first connecting member and the second connecting member to connect the first connecting member and the second connecting member.

[0015] A further technical solution is that the host housing includes a power housing and a wiring housing; the power housing is plug-actively connected to the wiring housing.

[0016] A further technical solution is that the Taylor frame comprises a telescopic rod and a fixing ring; the two ends of the telescopic rod are respectively connected to a fixing ring; the telescopic rod and the fixing ring are connected via a Hooke's hinge.

[0017] The beneficial technical effects of the present invention are as follows:

[0018] (1) The electric intelligent external frame connection structure of the present invention is provided with a first connecting member, a second connecting member and a fastener. The first connecting member, the second connecting member and the fastener hold the fixing ring to achieve the connection between the main housing and the fixing ring. The first connecting member connects the main housing, and the second connecting member only supports the main housing. Even if the distance between the first connecting member and the second connecting member changes with the change of the specification of the fixing ring, only the position of the second connecting member supporting the main housing changes, and the second connecting member can still support the main housing. That is, the electric intelligent external frame connection structure is a universal connection structure, which can adapt to external frame structures of different specifications and fix the main housing on the external frame. Avoid using multiple sets of structures for connection, reduce the model specifications of the connection structure, and thus reduce its production cost. At the same time, reduce the learning cost of the installer and the subsequent maintenance cost of the electric external frame.

[0019] (2) Further, the first connecting member includes a connecting head, which contacts the fixing ring to limit the position of the first connecting member. At the same time, a screw hole is provided on the connecting head to facilitate screw connection between the host housing and the first connecting member. The second connecting member includes a supporting head, which contacts the fixing ring to limit the position of the second connecting member. At the same time, the supporting head contacts and supports the host housing, and the connecting head and the supporting head cooperate to fix and support the host housing on the fixing ring.

[0020] (3) Furthermore, the second connecting member is arranged on a side of the first connecting member away from the axis of the fixing ring. Because the inner side of the fixing ring is the patient's limb, the mainframe housing on the fixing ring can only be arranged toward the outer side of the fixing ring, that is, the center of gravity of the mainframe housing is closer to the outer side of the fixing ring. The second connecting member only supports but does not connect to the mainframe housing, so the second connecting member is arranged on a side close to the outer side of the fixing ring to better support the fixing ring and ensure the stability of the connection between the mainframe housing and the fixing ring.

[0029] Figure 1 The three-dimensional structural schematic diagram shows the electric intelligent external frame connection structure of the present invention after being installed on the external frame. Figure 2 The three-dimensional structure diagram of the electric intelligent external frame connection structure of the present invention is shown. Figure 1 and Figure 2 , an electric intelligent external frame connection structure is used to connect the fixing ring 5 of the Taylor frame and the main body shell 1. The electric intelligent external frame connection structure includes a first connecting piece 2, a second connecting piece 3 and a fastener 4. The first connecting piece 2 passes through the inner hole 51 of the fixing ring 5, and the first connecting piece 2 is connected to the main body shell 1. The second connecting piece 3 passes through the outer hole 52 of the fixing ring 5. The fastener 4 simultaneously connects the first connecting piece 2 and the second connecting piece 3. Among them, the fastener 4 and the main body shell 1 are arranged on the opposite side of the fixing ring 5. The second connecting piece 3 contacts the main body shell 1. The fixing ring 5 is held by the first connecting piece 2, the second connecting piece 3 and the fastener 4 to realize the connection between the main body shell 1 and the fixing ring 5. Among them, the first connecting piece 2 is connected to the main body shell 1, and the second connecting piece 3 only supports the main body shell 1. Even if the distance between the first connecting piece 2 and the second connecting piece 3 changes with the change of the specification of the fixing ring 5, only the position of the second connecting piece 3 supporting the main body shell 1 changes, and the second connecting piece 3 can still support the main body shell 1 at this time. That is, the electric intelligent external frame connection structure is a universal connection structure, which can adapt to external frame structures of different specifications and fix the host housing 1 on the external frame. Avoid using multiple sets of structures for connection, reduce the model specifications of the connection structure, and thus reduce its production cost. At the same time, it reduces the learning cost of the installer and the subsequent maintenance cost of the electric external frame.

[0030] At this time, the second connecting member 3 is arranged on the side of the first connecting member 2 away from the axis of the fixing ring 5. Because the inner side of the fixing ring 5 is the patient's limb, the mainframe housing 1 on the fixing ring 5 can only be arranged toward the outer side of the fixing ring 5, that is, the center of gravity of the mainframe housing 1 is closer to the outer side of the fixing ring 5. The second connecting member 3 only supports but does not connect to the mainframe housing 1, so the second connecting member 3 is arranged on the side close to the outer side of the fixing ring 5 to better support the fixing ring 5.

[0031] Please refer to Figure 1 and Figure 2 The first connecting member 2 includes a connecting head 21 and a first rod 22. The first rod 22 passes through the inner hole 51. The connecting head 21 contacts the fixing ring 5 and the main housing 1 at the same time. The freedom of the first rod 22 is limited by the connecting head 21, and the first rod 22 and the main housing 1 are connected by the connecting head 21.

[0032] Preferably, the main housing 1 is connected to the first connecting member 2 by screws, and at least two first threaded holes 211 are provided on the connecting head 21. Specifically, a plurality of screws connect the main housing 1 and the first connecting member 2 through a plurality of first threaded holes 211. The provision of a plurality of screws can improve the connection strength and stability, and ensure the connection performance between the main housing 1 and the fixing ring 5.

[0033] Please refer to Figure 1 and Figure 2 The second connecting member 3 includes a supporting head 31 and a second rod 32. The second rod 32 passes through the outer hole 52. The supporting head 31 contacts the fixing ring 5 and the main housing 1 at the same time. The freedom of the second rod 32 is limited by the supporting head 31, and the main housing 1 is supported on the fixing ring 5 by the supporting head 31.

[0034] Preferably, a flat portion 321 is provided on the second rod portion 32 , and the second rod portion 32 can more stably support the fastener 4 through the flat portion 321 , thereby ensuring the connection stability between the fastener 4 and the second rod portion 32 .

[0035] Please refer to Figure 1 and Figure 2 , the fastener 4 contacts the fixing ring 5. That is, when the host housing 1 tends to move away from the fastener 4, the fastener 4 will resist the fixing ring 5, thereby limiting the movement of the host housing 1, and firmly fixing the host housing 1 on the fixing ring 5 to prevent the fixing ring 5 from moving or vibrating.

[0036] Preferably, the fastener 4 is a bolt. The first connecting member 2 and the second connecting member 3 are respectively provided with a second threaded hole 221. The fastener 4 simultaneously connects the second threaded holes 221 on the first connecting member 2 and the second connecting member 3 to connect the first connecting member 2 and the second connecting member 3. The rod of the bolt is screwed into the two second threaded holes 221 simultaneously to connect the first connecting member 2 and the second connecting member 3. The head of the bolt contacts the second rod 32 to limit the positional relationship between the bolt and the second connecting member 3.

[0037] Figure 3 A three-dimensional structural schematic diagram of a power supply housing in the electric intelligent external frame connection structure of the present invention is shown. Figure 4 The three-dimensional structure diagram of the wiring housing in the electric intelligent external frame connection structure of the present invention is shown. Figure 1 , Figure 3 and Figure 4 The host housing 1 includes a power housing 11 and a wiring housing 12. The host housing 1 is divided into the power housing 11 and the wiring housing 12 to reduce the weight of each component. When installing the host housing 1, the wiring housing 12 and the first connecting member 2 can be connected first, the first connecting member 2 can be fixed on the fixing ring 5, and then the power housing 11 and the wiring housing 12 can be connected. This makes the handling and installation process of the host housing 1 easier.

[0038] In this example, the power supply housing 11 is plugged into the active connection wiring housing 12. Specifically, two clamping bosses 111 are protruded on the power supply housing 11, and a clamping block 112 is provided on the clamping boss 111, and the two clamping blocks 112 are arranged facing each other. The opposite side surfaces of the wiring housing 12 are respectively provided with sliding grooves 121 for the clamping blocks 112 to be clamped. The clamping blocks 112 are slid into the sliding grooves 121 to achieve the plug-in connection between the power supply housing 11 and the wiring housing 12.

[0039] Please refer to Figure 1 The Taylor frame includes a telescopic rod 6 and a fixing ring 5. The two ends of the telescopic rod 6 are respectively connected to a fixing ring 5. The telescopic rod 6 is connected to the fixing ring 5 through a Hooke hinge 61. The connection of the Hooke hinge 61 allows a certain angle deviation between the two connected parts, thereby improving the flexibility of the electric intelligent external frame. At the same time, the Hooke hinge 61 has a self-locking performance to prevent the electric intelligent external frame from deviating during the treatment process, thereby ensuring the treatment effect of the orthopedic fixed external frame.

[0040] The specific assembly process of the present invention is as follows:

[0041] From top to bottom, pass the first rod 22 through the inner hole 51 on the fixing ring 5 until the connecting head 21 contacts the fixing ring 5. Pass the second rod 32 through the outer hole 52 on the fixing ring 5 until the supporting head 31 contacts the fixing ring 5. Select the first connecting member 2 and the second connecting member 3, and align the two second threaded holes 221. The inner hole 51 and the outer hole 52 are arranged adjacent to each other. Then move the fastener 4 through the two second threaded holes 221 at the same time to connect the first connecting member 2 and the second connecting member 3. Finally, screw the wiring housing 12 to the connecting head 21, plug and connect the wiring housing 12 and the power supply housing 11, and the supporting head 31 supports the host housing 1.

[0042] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
