Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a medical device used in surgery for scoliosis. Background Technology

[0002] Scoliosis is a deformity that occurs and develops in three-dimensional space, and axial rotation of the spine is one of the main deformities of scoliosis. Current scoliosis surgery involves installing pedicle screws and pre-bent titanium rods, followed by manipulations such as rod rotation, translation, intervertebral space widening, and compression to correct rotation. In these surgeries, if the intervertebral space between two adjacent vertebrae is too large, it is necessary to bring them closer together to reduce the space. However, currently, there are no suitable tools to move adjacent vertebrae with excessively large intervertebral spaces closer together. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a rotational orthopedic track device for scoliosis surgery, which can make two adjacent vertebrae with excessive intervertebral space move closer to each other, so as to reduce the gap between the two vertebrae to meet the requirements.

[0004] The present invention relates to a rotational orthopedic track device for scoliosis surgery, comprising two clamping arms that are hinged to each other and connected by a pin. Each clamping arm has a clamping end and a gripping end at its two ends, and the hinge point between the two clamping arms is located between the clamping end and the gripping end of each clamping arm. Each clamping end of each clamping arm is provided with two clamping arms that can move closer to or further away from each other.

[0005] This utility model relates to a rotational orthopedic track device for scoliosis surgery, wherein each clamping arm has a sleeve fixedly mounted on its clamping end. The sleeve has an axially arranged groove on its wall. A threaded rod is rotatably mounted inside the sleeve, and the threaded rod is arranged along the axial direction of the sleeve. The threaded rod has a first threaded section and a second threaded section with opposite directions of rotation. The two clamping arms that can move closer or further away from each other are a first clamping arm and a second clamping arm, respectively. The first clamping arm and the second clamping arm are threadedly connected to the first threaded section and the second threaded section, respectively. The ends of the first clamping arm and the second clamping arm that are away from the threaded rod both extend through the groove to the outside of the sleeve. The groove is adapted to the first clamping arm and the second clamping arm.

[0006] This utility model relates to a rotational orthopedic track device for scoliosis surgery, wherein each clamping arm has a sleeve fixedly mounted on its clamping end. The sleeve has an axially arranged groove on its wall. A threaded rod is rotatably mounted inside the sleeve. The threaded rod is arranged along the axial direction of the sleeve and has a first threaded section and a second threaded section with opposite directions of rotation. The two clamping arms that can move closer or further apart are a first clamping arm and a second clamping arm, respectively. The first clamping arm and the second clamping arm are threadedly connected to the first threaded section and the second threaded section, respectively. The first clamping arm and the second clamping arm are both slidably connected to the sleeve along the axial direction of the sleeve. The ends of the first clamping arm and the second clamping arm that are away from the threaded rod both extend through the groove to the outside of the sleeve.

[0007] This utility model relates to a rotational orthopedic track device for scoliosis surgery, wherein the inner wall of the sleeve is provided with an axially arranged groove, and the first clamping arm and the second clamping arm are each provided with a slider that cooperates with the groove, and the slider is located inside the groove.

[0008] This utility model relates to a rotational orthopedic track device for scoliosis surgery, wherein the inner wall of the sleeve is provided with an axially arranged strip slider, and the first clamping arm and the second clamping arm are both provided with a groove for cooperating with the strip slider, and the strip slider is located in the groove.

[0009] This utility model relates to a rotational orthopedic track device for scoliosis surgery, wherein each clamp arm includes a first and second sub-clamping arms that are parallel to each other. The gripping ends of the first and second sub-clamping arms are connected by a gripping rod. A sleeve is fixedly provided between the clamping ends of the first and second sub-clamping arms. The first and second sub-clamping arms of one clamping arm are located between the first and second sub-clamping arms of the other clamping arm. The pin includes a first pin and a second pin. The two first sub-clamping arms are arranged close to each other and are hinged to each other by the first pin. The two second sub-clamping arms are arranged close to each other and are hinged to each other by the second pin. The first and second pins are arranged coaxially. The axial direction of the sleeve is parallel to the axial direction of the first and second pins.

[0010] This utility model relates to a rotational orthopedic track device for scoliosis surgery, wherein both ends of the sleeve are provided with baffles, the clamping ends of the first and second clamping arms are respectively fixedly connected to the baffles at both ends of the sleeve, and the threaded rod is rotatably disposed between the two baffles.

[0011] This utility model relates to a rotational orthopedic track device for scoliosis surgery, wherein the two ends of the threaded rod are rotatably mounted on two baffles via bearings, and one end of the threaded rod passes through an adjacent baffle and extends to the outside of the sleeve and is fixedly connected to a rotating handle.

[0012] This utility model relates to a rotational orthopedic track device for scoliosis surgery, wherein the two ends of the threaded rod pass through their respective adjacent baffles and are rotatably mounted on the clamping ends of the first and second clamping arms via bearings, and one end of the threaded rod passes through the first or second clamping arm and is fixedly connected to a rotating handle.

[0013] The present invention relates to a rotational orthopedic track device for scoliosis surgery, wherein the gripping rod is rotatably connected between the gripping ends of the first and second clamp arms.

[0014] The difference between this novel derotation and correction track device for scoliosis surgery and existing technologies lies in the fact that, during use, the surgeon first adjusts the distance between the two clamping arms at each clamping end (i.e., by moving the two clamping arms closer together or further apart), ensuring that the distance between the two clamping arms is greater than the size of the vertebral body. Then, the surgeon grasps the gripping ends of the two clamping arms and moves them closer together or further apart. Because the two clamping arms are hinged together, the gripping ends of the two clamping arms also move closer together or further apart. Once the distance between the gripping ends of the two clamping arms is... After aligning the distance between two adjacent vertebrae, place the two clamping arms of one clamping arm on either side of one vertebra, and simultaneously place the two clamping arms of the other clamping arm on either side of the other vertebra. Then, move the two clamping arms of each clamping arm closer together until both pairs of clamping arms clamp the two vertebrae. Next, move the gripping ends of the two clamping arms closer together, causing the clamping ends of the two clamping arms to move closer together as well. The two vertebrae follow the clamping ends of the two clamping arms, moving closer together until the gap between the two vertebrae decreases to the required size. Finally, move the two clamping arms of each clamping arm away from each other to release the vertebrae, and then remove the device.

[0015] The present invention will be further described below with reference to the accompanying drawings. Attached Figure Description

[0025] Figure 10 This is a front sectional view of the sleeve in this utility model. Figure 2 . Detailed Implementation

[0026] like Figure 1 As shown, and in combination Figure 2-10 As shown, the scoliosis correction track device of this utility model includes two clamp arms 1 that are hinged to each other. The two clamp arms 1 are hinged together by a pin. The two ends of each clamp arm 1 are a clamping end and a gripping end, respectively. The hinge point between the two clamp arms 1 is located between the clamping end and the gripping end of each clamp arm 1. Each clamping end of the clamp arm 1 is provided with two clamping arms 14 and 8 that can move closer or further away from each other.

[0027] This utility model relates to a rotational correction track device for scoliosis surgery, wherein each clamping end of the clamping arm 1 is fixedly provided with a sleeve 7, such as... Figure 8 , 9 As shown in Figure 10, the sleeve 7 has an axially arranged slot 11 on its cylindrical wall. A threaded rod 10 is rotatably arranged inside the sleeve 7. The threaded rod 10 is arranged along the axial direction of the sleeve 7. The threaded rod 10 has a first threaded section and a second threaded section with opposite directions of rotation. The two clamping arms 14 and 8 that can move closer or further away from each other are the first clamping arm 14 and the second clamping arm 8, respectively. Nuts are fixed on both the first clamping arm 14 and the second clamping arm 8. The first clamping arm 14 and the second clamping arm 8 are respectively threadedly connected to the first threaded section and the second threaded section through the nuts on their own. The ends of the first clamping arm 14 and the second clamping arm 8 that are away from the threaded rod 10 both extend through the slot 11 to the outside of the sleeve 7. The slot 11 is adapted to the first clamping arm 14 and the second clamping arm 8.

[0028] The mutual adaptation of the slot 11 with the first clamping arm 14 and the second clamping arm 8 means that the width of the slot 11 is slightly larger than the width of the first clamping arm 14 and the second clamping arm 8, that is, there is a gap between the first clamping arm 14 and the second clamping arm 8 and the slot wall of the slot 11, but the gap is small.

[0029] When the threaded rod 10 is rotated, the first clamping arm 14 and the second clamping arm 8 pass through the slot 11, and the width of the slot 11 is slightly larger than the width of the two clamping arms 14 and 8. Therefore, the two clamping arms 14 and 8 are restricted by the slot 11 and cannot rotate with the threaded rod 10. Since the first clamping arm 14 and the second clamping arm 8 are respectively threaded to the first threaded section and the second threaded section with opposite directions of rotation, the two clamping arms 14 and 8 move closer to or further away from each other along the axial direction of the threaded rod 10 (which is also the axial direction of the sleeve 7).

[0030] Of course, the first clamping arm 14 and the second clamping arm 8 can also be installed on the sleeve 7 in the following way: a sleeve 7 is fixedly provided on the clamping end of each clamping arm 1, and the sleeve 7 has an axially arranged groove 11 on its wall. A threaded rod 10 is rotatably provided inside the sleeve 7. The threaded rod 10 is arranged along the axial direction of the sleeve 7. The threaded rod 10 has a first threaded section and a second threaded section with opposite directions of rotation. The two clamping arms 14 and 8 that can move closer or further away from each other are the first clamping arm 14 and the second clamping arm 8, respectively. Nuts are fixedly provided on both the first clamping arm 14 and the second clamping arm 8. The first clamping arm 14 and the second clamping arm 8 are respectively threadedly connected to the first threaded section and the second threaded section through the nuts on their own. The first clamping arm 14 and the second clamping arm 8 are slidably connected to the sleeve 7 along the axial direction of the sleeve 7. The ends of the first clamping arm 14 and the second clamping arm 8 that are away from the threaded rod 10 extend through the groove 11 to the outside of the sleeve 7.

[0031] In the above installation method, there is no restriction that the width of the slot 11 should be slightly larger than the width of the two clamping arms 14 and 8. The width of the slot 11 only needs to be wide enough for the two clamping arms 14 and 8 to pass through. That is to say, the slot 11 is not used to restrict the two clamping arms 14 and 8 to prevent them from rotating with the threaded rod 10. Instead, the two clamping arms 14 and 8 are slidably connected to the sleeve 7. In this way, the two clamping arms 14 and 8 cannot rotate with the threaded rod 10. When the two clamping arms 14 and 8 are slidably connected to the sleeve 7, the following two methods can be used: (1) The inner wall of the sleeve 7 is provided with an axially arranged sliding groove. The first clamping arm 14 and the second clamping arm 8 are both provided with a slider 12 that cooperates with the sliding groove. The slider 12 is located in the sliding groove. (2) The inner wall of the sleeve 7 is provided with an axially arranged strip slider. The first clamping arm 14 and the second clamping arm 8 are both provided with a sliding groove that cooperates with the strip slider. The strip slider is located in the sliding groove.

[0032] like Figure 4As shown, when the inner wall of the sleeve 7 is provided with a sliding groove and the two clamping arms 14 and 8 are provided with sliders 12, the inner wall of the sleeve 7 is provided with two oppositely arranged sliding grooves, and each of the two clamping arms 14 and 8 is provided with two sliders 12, which are located in the two sliding grooves respectively. When the threaded rod 10 rotates, due to the restriction of the sliders 12 and the sliding grooves, the two clamping arms 14 and 8 cannot rotate with the threaded rod 10, but can only slide along the sliding grooves by sliding their own sliders 12, that is, slide towards or away from each other along the axial direction of the sleeve 7 (which is also the axial direction of the threaded rod 10).

[0033] When the inner wall of the sleeve 7 is provided with strip-shaped sliders and the two clamping arms 14 and 8 are provided with sliding grooves, the inner wall of the sleeve 7 has two oppositely arranged strip-shaped sliders, and each of the two clamping arms 14 and 8 has two sliding grooves, with the two strip-shaped sliders located in the two sliding grooves respectively. When the threaded rod 10 rotates, due to the restriction of the strip-shaped sliders and sliding grooves, the two clamping arms 14 and 8 cannot rotate with the threaded rod 10, but can only slide along the strip-shaped sliders through their own sliding grooves, that is, slide towards or away from each other along the axial direction of the sleeve 7 (which is also the axial direction of the threaded rod 10).

[0034] like Figure 1-3 As shown in Figures 7-10, the scoliosis correction track device of this invention includes a first sub-arm 2 and a second sub-arm 3 that are parallel to each other. The two ends of the first sub-arm 2 and the second sub-arm 3 are the two ends of the clamp arm 1. That is, the gripping end of the clamp arm 1 is the gripping end of the first sub-arm 2 and the second sub-arm 3, and the clamping end of the clamp arm 1 is the clamping end of the first sub-arm 2 and the second sub-arm 3. The gripping ends of the first sub-arm 2 and the second sub-arm 3 are connected by a gripping rod 4. A sleeve 7 is fixedly provided between the clamping ends of the first sub-arm 2 and the second sub-arm 3. Under the fixing action of the sleeve 7, the first sub-arm 2 and the second sub-arm 3 can always remain parallel. The first sub-arm 2 and the second sub-arm 3 of one clamp arm 1 are located between the first sub-arm 2 and the second sub-arm 3 of another clamp arm 1, that is, one clamp arm 1 is fitted between another clamp arm 1. The pin includes a first pin 5 and a second pin 6. The two first jaw arms 2 are arranged close to each other and are hinged to each other by the first pin 5. The two second jaw arms 3 are arranged close to each other and are hinged to each other by the second pin 6. The first pin 5 and the second pin 6 are arranged coaxially. The axial direction of the sleeve 7 is parallel to the axial direction of the first pin 5 and the second pin 6.

[0035] like Figure 1 , 2 As shown, the axial directions of the gripping rod 4, the first pin 5 and the second pin 6, the sleeve 7 and the threaded rod 10 are all parallel to each other. Of course, in this embodiment, the sleeve 7 and the threaded rod 10 are arranged coaxially.

[0036] For each clamp arm 1, the gripping rod 4, the first sub-clamp arm 2, the second sub-clamp arm 3, and the sleeve 7 together form a rectangular structure. That is, when a clamp arm 1 rotates around the first pin 5 and the second pin 6, the first sub-clamp arm 2 and the second sub-clamp arm 3 constituting the clamp arm 1, as well as the gripping rod 4 and the sleeve 7 connecting the two sub-clamp arms, all rotate together. The operator grasps the gripping rods 4 at the gripping ends of the two clamp arms 1 and moves the two gripping rods 4 closer to each other or further away. Driven by the two gripping rods 4, the gripping ends of the two clamp arms 1 move closer to each other or further away. Since the two clamp arms 1 are hinged to each other, that is, the two first sub-clamp arms 2 are hinged through the first pin 5 and the two second sub-clamp arms 3 are hinged through the second pin 6, and the first pin 5 and the second pin 6 are arranged coaxially, the clamping ends of the two clamp arms 1 also move closer to each other or further away. Since the two sleeves 7 are respectively fixed on the clamping ends of the two clamp arms 1, the two sleeves 7 also move closer to each other or further away. Thus, the clamping arms respectively set on the two sleeves 7 also move closer to each other or further away with the two sleeves 7.

[0037] like Figure 9 , 10 As shown, the present invention relates to a rotational orthopedic track device for scoliosis surgery, wherein both ends of the sleeve 7 are fixedly provided with baffles 13, and the clamping ends of the first clamping arm 2 and the second clamping arm 3 are respectively fixedly connected to the baffles 13 at both ends of the sleeve 7, thereby achieving the purpose of fixing the sleeve 7 between the clamping ends of the first clamping arm 2 and the second clamping arm 3.

[0038] The threaded rod 10 is rotatably positioned between two baffles 13, specifically as follows: Figure 10 As shown, and in combination Figure 1 , 2 As shown in Figures 3 and 5, the two ends of the threaded rod 10 are rotatably mounted on two baffles 13 via bearings. One end of the threaded rod 10 passes through the adjacent baffle 13 and extends to the outside of the sleeve 7, where it is fixedly connected to a rotating handle 9. At this time, although the first clamping arm 2 and the second clamping arm 3 are fixed to the baffles 13, their clamping ends are higher than the position of the threaded rod 10 on the baffles 13. This ensures that the clamping arms do not obstruct one end of the threaded rod 10 from extending from inside the sleeve 7 to outside and being fixedly connected to the rotating handle 9. The purpose of the rotating handle 9 is to facilitate the operator's rotation of the threaded rod 10.

[0039] Of course, besides the aforementioned method where the threaded rod 10 is rotatably positioned between the two baffles 13, the following methods can also be used: such as Figure 9 As shown, and in combination Figure 6As shown, both ends of the threaded rod 10 pass through their respective adjacent baffles 13 and are rotatably mounted on the clamping ends of the first clamping arm 2 and the second clamping arm 3 via bearings. One end of the threaded rod 10 passes through the first clamping arm 2 or the second clamping arm 3 and is fixedly connected to a rotating handle 9. At this time, the clamping ends of the first clamping arm 2 and the second clamping arm 3 pass through the axis of the threaded rod 10 / sleeve 7, so that both ends of the threaded rod 10 can be rotatably mounted on the clamping ends of the first clamping arm 2 and the second clamping arm 3 via bearings after passing through their respective adjacent baffles 13.

[0040] like Figure 1 , 2 As shown, this utility model relates to a derotation orthopedic track device for scoliosis surgery, wherein the gripping rod 4 is rotatably connected between the gripping ends of the first clamp arm 2 and the second clamp arm 3. In this way, when the surgeon grips the gripping rod 4 and moves the gripping ends of the two clamp arms 1 closer or further apart, there is no relative rotation between the surgeon's hand and the gripping rod 4, facilitating operation. Otherwise, if the gripping rod 4 were fixedly connected to the gripping ends of the first clamp arm 2 and the second clamp arm 3, the surgeon would need to constantly adjust the relative position between their hand and the gripping rod 4, which would be inconvenient.

[0041] like Figure 1 , 2As shown, in the scoliosis correction surgery of this utility model, when using the rotational orthopedic track device, the surgeon first adjusts the distance between the two clamping arms 14 and 8 at the clamping end of each clamping arm 1 (i.e., rotating the rotating handle 9 to rotate the threaded rod 10, so that the two clamping arms 14 and 8 move closer or further apart), so that the distance between the two clamping arms 14 and 8 is greater than the size of the vertebral body. Then, the surgeon grasps the gripping rod 4 at the gripping end of the two clamping arms 1 and makes it move closer or further apart. Under the action of the gripping rod 4, the gripping ends of the two clamping arms 1 also move closer or further apart. Since the two clamping arms 1 are hinged to each other (i.e., the two first sub-clamping arms 2 are hinged through the first pin 5, and the two second sub-clamping arms 3 are hinged through the second pin 6, and the first pin 5 and the second pin 6 are arranged coaxially), the clamping ends of the two clamping arms 1 also move closer or further apart, and the two sleeves 7 also move closer or further apart. When the two clamping arms After the distance between the clamping ends of 1 corresponds to the distance between two adjacent vertebrae, that is, after the distance between the clamping arms of one sleeve 7 and the clamping arms of another sleeve 7 corresponds to the distance between two adjacent vertebrae, the two clamping arms 14 and 8 of the clamping end of one clamping arm 1 are placed on both sides of one vertebrae, and at the same time, the two clamping arms 14 and 8 of the clamping end of the other clamping arm 1 are placed on both sides of another vertebrae. Then, the two clamping arms 14 and 8 of the clamping end of each clamping arm 1 move closer to each other until the two pairs of clamping arms clamp the two vertebrae respectively. Then, the gripping ends of the two clamping arms 1 move closer to each other, so the clamping ends of the two clamping arms 1 and the sleeves 7 on them also move closer to each other at the same time. Since the vertebrae are clamped between the two clamping arms 14 and 8 of the sleeve 7, the two vertebrae follow the clamping ends of the two clamping arms 1 and the sleeves 7 on them and move closer to each other at the same time until the gap between the two vertebrae becomes smaller to meet the requirements. Finally, release the cone by moving the two clamping arms 14 and 8 at the clamping end of each clamp arm 1 away from each other, and then remove the utility model.
