Description

Technical Field

[0001] This invention belongs to the field of rehabilitation training equipment technology, specifically a thoracic surgical rib fracture fixation device. Background Technology

[0002] Posterior fixation of rib fractures is primarily achieved through external or internal fixation. External fixation uses tools such as chest straps, adhesive tape, or bandages to hold the ribs to the chest wall, reducing movement at the fracture ends and thus alleviating pain, bleeding, and swelling. Internal fixation involves surgically suturing the ribs to surrounding tissues or using materials such as metal plates or pins. This method is suitable for multiple rib fractures and single rib fractures with significant displacement.

[0003] External fixation methods generally present certain problems when used for auxiliary fixation of individuals. Existing external fixation methods typically involve wrapping the patient's rib area with bandages, often using large-area Velcro adhesive. To maintain the tightness of the bandage during adhesion, the contact ends need to be pulled forcefully, applying pressure to the body. However, to prevent pressure sores caused by obstructed local blood circulation during long-term use, the bandage needs to be loosened periodically, but not completely. However, when used on elderly individuals, the elasticity of the bandage means that it will completely unravel when the adhesive is released, requiring subsequent re-tensioning and fixation. Due to the poor physical function of the elderly, it is difficult to ensure that the bandage maintains its tightness when re-fixation is needed. Therefore, to address the above issues, a thoracic surgical rib fracture fixation device is proposed. Summary of the Invention

[0004] To address the issue raised in the background art regarding the poor physical function of the elderly population, making it difficult to ensure that the bandage maintains its tightness when re-fixation is needed, this invention provides a thoracic surgical rib fracture fixation device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a thoracic surgical rib fracture fixation device, comprising a fixation bandage, and further comprising: The pulling element is fitted inside the fixing bandage; The positioning element is installed on the side wall of the fixing bandage and is connected to the pulling element; The movable component is located on the inner wall of the fixed bandage and is symmetrically arranged on the upper and lower sides of the pulling component; The pulling member includes a pull strap that is annularly sleeved in the inner cavity of the fixed bandage. One end of the pull strap is used to tighten the opening of the fixed bandage, and the other end of the pull strap passes through the fixed bandage and extends outward. A first connecting strap is installed at the end of the pull strap located outside the fixed bandage. Second connecting straps are installed on both the upper and lower sides of the first connecting strap, and the second connecting straps are engaged with the movable member by a snap fastener. The positioning element includes a fixing strap installed on the outer wall of the fixing bandage. An elastic band is installed on the fixing strap, and the fixing strap and the elastic band are respectively equipped with positioning holes and positioning blocks that engage with each other. The elastic band is fastened to the end of the buckle strap through the buckle on the buckle strap. The movable component includes an expansion bag and a rubber airbag mounted on the pull belt, with the rubber airbag communicating with the expansion bag via an air groove.

[0006] Preferably, the fixing bandage includes a band body, and the inside of the band body has an annular cavity for the movement of the tension strap and the movable component; A rubber gasket for compressing the rubber airbag is installed in the annular cavity.

[0007] Preferably, the second connecting strip has embedded Velcro, and the engaging end of the card strip and the card slot is made of rigid material; The cartridge is shaped like an inverted "L", and the outer wall at the bottom of the cartridge is fitted with a rubber ring with a size larger than the inner diameter of the slot.

[0008] Preferably, a pull cord is installed at the end of the cassette away from the second connecting belt, and a rubber ball is installed at one end of the pull cord.

[0009] Preferably, the fixing belt is equipped with a limiting hook for limiting the pull rope. The lower end of the limiting hook is an upward-opening ring, and the limiting hook is arc-shaped as a whole. The interval value of the upward-opening area at the bottom of the limiting hook is smaller than the outer diameter value of the pull rope.

[0010] Preferably, there is a gap between the fixing strap and the elastic band, and a hook and loop fastener connected to the male hook and loop fastener is installed on one side wall of the fixing strap at the gap; The buckle strap is made of rigid spring sheet.

[0011] Preferably, the number of positioning holes is several, the size of the several positioning holes is adapted to the size of the positioning block, and the number of positioning blocks is one.

[0012] Preferably, the rubber airbag is in the shape of a right triangle, and the rubber airbag is symmetrically installed on the upper and lower sides of the pull strap, with the inner cavity of both communicating with the air groove.

[0013] Preferably, the air groove is formed inside the pull strap, the air groove is shaped like a horizontal "H", and each air outlet end of the air groove is connected to the expansion bag.

[0014] Preferably, the expansion bag is specifically composed of half a hollow cylindrical bag and is elastic; When the rubber air bladder is compressed, the gas inside it enters the interior of the expansion bag through the air groove, and the expansion bag gradually expands.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention, through the coordination of structures such as pullers and positioning elements, allows the positioning block to be pulled out from the positioning hole when the bandage needs to be loosened periodically. The pull bandage, secured by the male and female Velcro straps, will not suddenly and completely loosen due to its own elasticity. Simultaneously, the positioning block is sequentially snapped into the next positioning hole, and the connection between the male and female Velcro straps can be released for fine-tuning. This effectively prevents elderly users from expending excessive physical effort to periodically loosen the bandage under long-term fixation, thereby improving the external fixation effect for rib fractures.

[0016] This invention utilizes a combination of pulling and moving components. The pull strap moves the rubber airbag, gradually bringing it into contact with a rubber pad. The rubber pad compresses the airbag, causing it to expand until it becomes semi-cylindrical. At this point, the expansion bag provides several vertical supports to the back area. Simultaneously, according to… Figure 6 It can be seen that one group compresses the back of the body, while the other group compresses the annular cavity of the belt, creating bidirectional contact on both sides. After the belt is put on, external auxiliary fixation and support are provided to enhance the resistance of the belt to body bending; at the same time, it avoids the effect of a significant decrease in resistance due to air leakage in a single piece; thus greatly improving the effect of orthopedic fixation of rib fractures in thoracic surgery.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1 to 11 As shown, the present invention provides a fixation device for thoracic rib fractures, including a fixation bandage 1, and further comprising: Pulling element 2 is fitted inside the fixing bandage 1; Positioning element 3 is installed on the side wall of fixing bandage 1 and is connected to pulling element 2; The movable component 4 is located on the inner wall of the fixed bandage 1 and is symmetrically arranged on the upper and lower sides of the pulling component 2. The pulling member 2 includes a pull strap 21 that is annularly sleeved in the inner cavity of the fixed bandage 1. One end of the pull strap 21 is used to tighten the opening of the fixed bandage 1, and the other end of the pull strap 21 passes through the fixed bandage 1 and extends outward. A first connecting strap 22 is installed at the end of the pull strap 21 located outside the fixed bandage 1. A second connecting strap 23 is installed on both the upper and lower sides of the first connecting strap 22, and the second connecting strap 23 is engaged with the movable member 4 through a snap fastener 26. The positioning component 3 includes a fixing strap 31 installed on the outer wall of the fixing bandage 1. An elastic band 33 is installed on the fixing strap 31, and the fixing strap 31 and the elastic band 33 are respectively equipped with a positioning hole 32 and a positioning block 34 for engaging. The elastic band 33 is fastened to the end of the buckle 26 through the buckle 37 on the buckle strap 36. The movable component 4 includes an expansion bag 43 and a rubber airbag 41 disposed on the pull belt 21. The rubber airbag 41 is connected to the expansion bag 43 through an air groove 42.

[0021] like Figure 3 and Figure 4 As shown, the fixed bandage 1 includes a band body 11, and the inside of the band body 11 is provided with an annular cavity for the pull strap 21 and the movable member 4 to move. A rubber gasket 12 for compressing the rubber airbag 41 is installed in the annular cavity.

[0022] The above scheme is adopted: the size of the annular cavity inside the belt body 11 is larger than the size of the pull belt 21, thereby ensuring the smooth movement of the pull belt 21 in the annular cavity. The specific installation position of the rubber gasket 12 can be changed accordingly based on the size of the rubber airbag 41, and the size of the rubber gasket 12 can also be adjusted according to the actual usage. Figure 3 and Figure 5 It can be seen that the installation position of the rubber pad 12 corresponds to the lower end of the inclined surface of the rubber airbag 41. When the rubber airbag 41 moves in the annular cavity, causing the rubber pad 12 to gradually squeeze the rubber airbag 41, the gas inside the rubber airbag 41 will enter the interior of the expansion bag 43 through the air groove 42, causing the expansion bag 43 to gradually expand into a cylindrical shape.

[0023] like Figure 7 and Figure 8 As shown, the second connecting strip 23 has a Velcro 25 embedded in it, and the engaging end of the card strip 26 and the slot 37 is made of rigid material. The cassette 26 is shaped like an inverted "L", and the outer wall at the bottom of the cassette 26 is fitted with a rubber ring with a size larger than the inner diameter of the latch 37.

[0024] Using the above solution: when the rubber ring on the outer wall of the bottom end of the cartridge 26 passes through the inlet 37, the rubber ring will be stuck below the inlet 37. At the same time, even if the cartridge 26 moves slightly upward, it will not immediately disengage from the inside of the inlet 37, and the two will still maintain the locking effect.

[0025] like Figure 7 and Figure 9 As shown, a pull cord 24 is installed at the end of the cassette 26 away from the second connecting cord 23, and a rubber ball is installed at one end of the pull cord 24.

[0026] The above solution will be adopted: Figure 9The placement and size of the rubber ball can be clearly seen. Its small size will prevent discomfort after wearing it. The pull cord 24 is also limited and suspended by the positioning component 3.

[0027] like Figure 9 As shown, a limiting hook 35 for limiting the pull rope 24 is installed on the fixing belt 31. The lower end of the limiting hook 35 is an upward-opening ring, and the limiting hook 35 as a whole is arc-shaped. The interval value of the upward-opening area at the bottom of the limiting hook 35 is smaller than the outer diameter value of the pull rope 24.

[0028] Using the above solution: the circular area with the bottom opening facing upwards of the elastic band 33 can limit the pull cord 24 while allowing the pull cord 24 to smoothly detach from its inside and out. Furthermore, the thickness of the limiting hook 35 is relatively small, so it will not cause discomfort to the body when actually worn.

[0029] like Figure 8 and Figure 9 As shown, there is a gap between the fixing strap 31 and the elastic strap 33, and a hook and loop fastener 38 connected to the male hook and loop fastener 25 is installed on one side wall of the fixing strap 31 in the gap. The buckle strap 36 is made of rigid spring.

[0030] The above scheme is adopted: continuously pull the buckle 26 and the second connecting strap 23 to connect the male Velcro 25 on the second connecting strap 23 to it, which serves as the first step of fixation. Then, due to the locking effect of the buckle 36 on the buckle 26, the elastic band 33 will move synchronously. During this process, the positioning block 34 on the elastic band 33 will be locked inside the positioning hole 32 at the corresponding distance position. First, the male Velcro 25 and the female Velcro 38 are used to fix it first. Then, the elastic band 33 is pulled to make the positioning block 34 lock in the positioning hole 32. When the elastic band 33 is pulled, the elastic band 33 applies a certain pulling force to the second connecting strap 23 and the buckle 26, thereby improving the overall tightness of the belt body 11 on the human body. At the same time, when it is necessary to loosen the belt body 11 periodically, since the elderly have poor physical strength, if they untighten the belt body 11 as a whole, they will have to spend too much energy to tighten it again. When this solution needs to be loosened, it is secured by the double fastening of the male and female Velcro straps 25 and the positioning block 34 and the positioning hole 32. When loosening, simply move the positioning block 34 into the next positioning hole 32 first, and then adjust the connection area between the male and female Velcro straps 25 and 38. When the positioning block 34 and the positioning hole 32 are untied, since the male and female Velcro straps 25 and 38 are still connected, the belt body 11 will not be quickly and completely loosened by the elasticity of the pull strap 21 and the belt body 11 itself after the positioning block 34 and the positioning hole 32 are untied.

[0031] like Figure 7 As shown, there are several positioning holes 32, the size of which is adapted to the size of the positioning block 34, and there is one positioning block 34.

[0032] Using the above scheme, the specific number, shape, and size of the positioning holes 32 can be set according to the actual usage.

[0033] like Figure 3 As shown, the rubber airbag 41 has a right-angled triangle shape. The rubber airbag 41 is symmetrically installed on the upper and lower sides of the pull strap 21, and the inner cavity of both is connected to the air groove 42. Air groove 42 is located inside the pull belt 21. The shape of air groove 42 is a horizontal "H" shape, and each air outlet of air groove 42 is connected to expansion bag 43.

[0034] like Figure 3 , Figure 5 and Figure 6 As shown, the expansion bag 43 is specifically composed of half a hollow cylindrical bag and is elastic; When the rubber airbag 41 is compressed, the gas inside it enters the interior of the expansion bag 43 through the air groove 42, and the expansion bag 43 will gradually expand.

[0035] Using the above scheme: when the interior of several expansion bags 43 is filled with gas and becomes cylindrical, the expansion bags 43 will provide several vertical supports to the back area of ​​the person, and at the same time, according to... Figure 6 It can be seen that there are two sets of expansion bags 43 located above the pull strap 21, and there is a gap between the two sets. When both sets are filled with air, one set squeezes the back of the body, and the other set squeezes the annular cavity of the belt body 11, resulting in bidirectional contact on both sides. After the belt body 11 is worn, it provides auxiliary support and enhances the resistance of the belt body 11 to the bending of the body. At the same time, it avoids the effect of a significant decrease in resistance due to leakage of a single piece. Furthermore, the thickness and material hardness of the moving part 4 and the pull part 2 will not affect the normal wearing of the belt body 11 or the comfort of the body.

[0036] Working principle and usage process of this invention: First, pull the belt 11 to its maximum extent and place it over the rib area, so that the bottom end of the buckle 26 passes through the buckle 37 and is positioned below it. Connect the buckle 26 to the elastic band 33 through the buckle 37. At this time, pull down the upper pull cord 24. Pulling the upper pull cord 24 downward will cause it to move the upper pull cord 21 gradually outward inside the belt 11 through the elastic band 33, the buckle 26, and the second connecting band 23, so that the belt 11 tightens the body. As it moves continuously, the male Velcro 25 on the second connecting band 23 will come into contact with the female Velcro 38. At this time, press the male Velcro 25 and the female Velcro 38 together and fix them. After they are fixed, pull the elastic band 33 so that the positioning block 34 is fastened to the corresponding positioning hole 32 for the second fixation. Subsequently, when the upper pull strap 21 is pulled, the rubber airbag 41 gradually comes into contact with the rubber pad 12 as the pull strap 21 moves. The rubber pad 12 gradually presses the rubber airbag 41, causing the gas inside the rubber airbag 41 to enter the interior of the expansion bag 43 through the air groove 42. At this time, after the expansion bag 43 is filled with gas and expands, it will gradually take the shape of an airbag bag that is approximately half-cylindrical. (See reference for details.) Figure 6 Half of the upper pull strap 21 is in contact with the body, and the other half is in contact with the strap 11. After the upper pull strap 21 is installed, the lower pull strap 21 is also fixed in the same way. When it is necessary to loosen the strap 11 periodically, any one of the upper and lower layers can be loosened first. The positioning block 34 is pulled out from the inside of the positioning hole 32. At this time, due to the adhesion and fixation of the male Velcro 25 and the female Velcro 38, the strap 21 will not suddenly loosen completely due to its own elasticity. The positioning block 34 is then moved into the next positioning hole 32 to reduce the tension of the strap 21. At the same time, the adhesion and fixation between the male Velcro 25 and the female Velcro 38 can be loosened. At this time, due to the engagement of the positioning block 34 and the positioning hole 32, the strap 21 will not loosen completely. This effectively avoids the need for the elderly to exert too much physical effort to complete the periodic loosening under the premise of long-term fixation, thereby improving the external fixation effect for rib fractures.
