Description

Technical Field

[0001] This utility model belongs to the field of skeletal correction technology, and in particular relates to a combined support frame. Background Technology

[0002] The human body has 206 bones, which are interconnected to form the human skeleton. The skeleton is divided into three main parts: the skull, the trunk, and the limbs. There are 29 skull bones, 51 trunk bones, and 126 limb bones. Skeletalization is the basis for the complexity of biological structures, and the skeletal system is also a limiting factor in the evolution of biological morphology. The skeleton is a hard organ that makes up the endoskeleton of vertebrates. Its functions are to move, support and protect the body, produce red blood cells and white blood cells, and store minerals.

[0057] The combined bracket of this utility model will now be described in more detail with reference to the schematic diagrams, which illustrate preferred embodiments of this utility model. It should be understood that those skilled in the art can modify the utility model described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the utility model.

[0058] Example 1

[0059] like Figures 1-9 A modular support, comprising:

[0060] N connecting rods 6 are arranged along the Y direction, with gaps between adjacent connecting rods 6 for the central bone needle to pass through; each connecting rod 6 extends along the X direction, where N=2;

[0061] A pair of end clips 2 are connected by a first connecting rod 6 and a second connecting rod 6; an end bone pin 1 is threaded onto the end clip 2.

[0062] Several sliding pin clips 3 are provided, each of which is fitted onto an adjacent pair of connecting rods 6 and has a central bone needle threaded onto it, passing through the gap. The position of the sliding pin clip 3 on the connecting rod 6 can be adjusted before it is pressed down.

[0063] The stent is fixed to the human skeleton by the end bone pin 1 and the middle bone pin thread, ultimately achieving the purpose of treatment fixation.

[0064] In this embodiment, the X and Y directions are the same as in other embodiments.

[0065] Among them, the end bone needle 1 and the middle bone needle are both fully threaded bone needles, which can prevent the problem of thread damage and misalignment caused by different tooth pitches in existing products.

[0066] Taking the distal bone pin 1 as an example, the above problems will be explained:

[0067] The existing product's end bone pin includes two threaded sections, one of which engages with the end pin clamp thread, and the other is screwed into the bone. The two threaded sections have different tooth pitches.

[0068] In existing products, the end bone pin is first screwed onto the end nail clamp, and then the end bone pin is screwed into the bone.

[0069] During the process of screwing the end bone pin into the bone, because the rigidity of the end pin clamp is greater than that of the bone and the pitch of the two threaded segments, thread decay and misalignment problems occur in the bone during this process.

[0070] Because the thread of the end bone pin 1 is a full thread, the thread that screws into the bone is consistent with the thread on the end pin clip 2, thereby avoiding the above-mentioned problems.

[0071] The insertion depth and the distance between the clips and the skin can be preset before the bracket is inserted.

[0072] like Figure 6 The end clip 2 includes:

[0073] A first rod holder 21 and a first needle holder 22 connected to the first rod holder 21, with the first rod holder 21 facing the other end nail clip 2;

[0074] The first rod holder 21 has a pair of first rod holes 211 extending along the X direction and a first clamping groove 23 extending along the Z direction; the first needle holder 22 has a first threaded hole 221, which is a through hole.

[0075] The first rod hole 211 connects to the first clamping groove 23; the first rod hole 211 passes through the end face A of the first rod seat 21 facing the other end nail clip 2; the first clamping groove 23 passes through the end face B of the first rod seat 21 away from the bone;

[0076] The end bone pin 1 is threaded into the first threaded hole 221;

[0077] The first connecting rod 6 and the second connecting rod 6 both engage with the first rod hole 211 on the two end nail clips 2 and protrude into the first clamping groove 23.

[0078] The end clamping plate 7 is installed in the first clamping groove 23 and abuts against the outer edges of the first connecting rod 6 and the second connecting rod 6;

[0079] The end fastener passes through the end clamping plate 7 along the Z-direction and is threadedly connected to the first rod seat 21. In this embodiment, the end fastener is a screw.

[0080] like Figure 5 As shown, the end clamping plate 7 includes a clamping surface 71 that fits against the connecting rod 6 and a clamping hole 72 through which the end fastener passes.

[0081] like Figure 4 Along the Z direction, the end clamping piece 7 and the first clamping groove 23 form a preset gap.

[0082] like Figure 9 As shown, the sliding pin clip 3 includes:

[0083] A pair of second rod holders 31 are arranged along the Y direction, and a pair of second rod holes 311 extending along the X direction are opened on them;

[0084] A pair of No. 2 needle holders 32 are arranged along the X direction, and No. 2 threaded holes 321 are opened on them. The No. 2 threaded holes 321 are through holes.

[0085] The No. 2 rod holder 31 is connected to the No. 2 needle holder 32; the inner edges of all the No. 2 rod holders 31 and No. 2 needle holders 32 form a closed No. 2 clamping groove 33;

[0086] The second rod hole 311 connects to the second clamping groove 33; the second rod hole 311 penetrates the second rod seat 31;

[0087] The central bone needle is threaded into the No. 2 threaded hole 321.

[0088] The connecting rod 6 engages with the corresponding second rod hole 311 and protrudes into the second clamping groove 33.

[0089] The middle clamping plate 4 is installed in the second clamping groove 33 and abuts against the outer edge of the connecting rod 6;

[0090] The central fastener passes through the central clamping plate 4 along the Z direction and is threadedly connected to the groove surface of the second clamping groove 33.

[0091] In this embodiment, the central fastener is a locking screw 5.

[0092] Installation method of this modular bracket:

[0093] Step 1: Pre-tighten the end bone pin 1 to the end nail clip 2.

[0094] Step 2: Continue to screw the end bone pin 1 to screw the end bone pin 1 into the bone.

[0095] Step 3: Twist the middle bone pin onto the sliding pin clip 3 and the bone.

[0096] Example 2

[0097] Based on Example 1, such as Figures 10-11 By increasing the number of connecting rods 6 and sliding nail clips 3, the central bone nail is expanded outward along the Y direction to cope with more complex conditions.

[0098] In this embodiment, three connecting rods 6 are included, arranged along the Y direction, with a gap formed between adjacent connecting rods 6 for the central bone needle to pass through; each connecting rod 6 extends along the X direction.

[0099] A pair of end clips 2 are connected by a first connecting rod 6 and a second connecting rod 6; an end bone pin 1 is threaded onto the end clip 2.

[0100] Several sliding pin clips 3 are provided, each of which is fitted onto an adjacent pair of connecting rods 6 and has a central bone needle threaded onto it, passing through the gap. The position of the sliding pin clip 3 on the connecting rod 6 can be adjusted before it is pressed down.

[0101] Among them, "the first connecting rod 6" refers to the first connecting rod arranged along the Y direction.

[0102] "Second connecting rod 6" refers to the connecting rod adjacent to the first connecting rod 6.

[0103] Example 3

[0104] like Figure 12 Based on Example 1, the position of the last connecting rod 6 in the X direction is changed to expand the middle bone nail outward along the X direction.

[0105] Example 4

[0106] like Figure 13 Based on Example 2, such as Figures 10-12 By increasing the number of connecting rods 6 and sliding nail clips 3, the central bone nail is expanded outward to cope with more complex conditions.

[0107] In this embodiment, the central bone screw is expanded outward along the X and Y directions.

[0108] The above are merely preferred embodiments of this utility model and do not constitute any limitation on this utility model. Any equivalent substitutions or modifications made by those skilled in the art to the technical solutions and contents disclosed in this utility model without departing from the scope of the technical solutions of this utility model shall still fall within the protection scope of this utility model.
