Description

Guide device {APPARATUS FOR GUIDE}

The description below relates to the guide device.

Pedicle screw insertion is a surgical method to correct spinal deformity and ensure stability through spinal fixation using pedicle screws. A screw is inserted into a position called the pedicle of the vertebra, and a metal bar is inserted into the hole in the head of the pedicle screw inserted into the pedicle of the vertebra at various levels to connect adjacent vertebrae to correct or fix the spine. It is to achieve effect. When performing various orthopedic procedures targeting the spine, it is very important to easily access the target area while avoiding damage to other parts of the body. To reduce the risk of such damage, the surgeon's skill level can be increased or guides targeting the spine can be used. In particular, when inserting a screw into the pedicle, an incision is made on the patient's back and the surgery is performed while viewing the upper surface of the vertebra. However, only the upper surface of the pedicle can be directly observed, and it is difficult to know the exact direction of the pedicle. In addition, when pedicle screw insertion is performed using a percutaneous approach, the position of the pedicle cannot be confirmed directly, and the screw insertion surgery has to be performed after confirming the pedicle surface through an x-ray image and a very small incision in the skin. Therefore, if surgery is performed without knowing the exact direction of the pedicle screw, the screw may penetrate the pedicle and enter the spinal canal, causing damage to the spinal nerve.

FIG. 1 is a diagram showing the spinal column and spine, FIG. 2 is a perspective view of a guide device according to an embodiment, and FIG. 3 is a view showing an object guided by a guide device according to an embodiment.

Referring to FIGS. 1 to 3, the guide device 1 guides the object 2 while coupled to the spine 3 so that the object 2 can be inserted into the target position in an appropriate direction into the spine. You can. The guide device (1) can be used for pedicle screw insertion surgery to correct spinal deformity and ensure stability. For example, by utilizing a guide device (1), a screw is inserted into a location called the pedicle of the spine and a metal bar is inserted into the hole in the head of the pedicle screw inserted into the pedicle of the vertebra at several levels nearby. By connecting one vertebra, the effect of correcting or fixing the spine can be achieved. Meanwhile, the guide device 1 can be applied not only to the spine 3 but also to any bone constituting the spinal column. Since the guide device 1 can three-dimensionally adjust the insertion position and angle of the object 2, the user can accurately perform the planned surgery through simulation, etc. For example, the guide device 1 can perform an order within a small error range, such as the direction in which an object is inserted into the spine 3 determined through medical image data, etc. In addition, if the guide device 1 is used, , Since the surgery can be performed according to the guide manual, the risks associated with the difficulty in directly checking the pedicle can be reduced even when a doctor with low skill performs the surgery. Here, the object 2 may include a bone fixation material such as a pedicle screw or K-wire. For example, the guide device 1 may include a housing 11, a first angle adjustment portion 12, a second angle adjustment portion 13, a center adjustment portion, and a grip portion 15. Here, the housing 11, the first angle adjusting unit 12, and the second angle adjusting unit 13 are each formed in two pieces, and may be disposed on both sides of the center adjusting unit 14, respectively. The guide device 1 not only has such a symmetrical structure, but, although not shown, the housing 11, the first angle adjuster 12, and the second angle adjuster 13 each have a center adjuster ( 14) may also include a type formed only on one side.

The housing 11 can penetrate the object 2. Specifically, the housing 11 may be configured to substantially directly guide the insertion of the object 2 by penetrating it. For example, housing 11 may include a frame and a hole.

The frame may be formed into a long shape that is connected to the first angle determining member 122 and moves integrally. The coupling angle between the frame and the first angle determining member 122 may be such that the virtual plane on which the first angle determining member 122 moves and the central axis of the frame are parallel. For example, the upper end of the frame may be connected to the first angle determining member 122, and the cross-sectional area of the lower end of the frame may become smaller as it goes downward. According to this structure, the view of the bottom of the frame is secured, so the process of insertion of the object 2 into the pedicle through the housing 11 and the insertion position or angle can be easily confirmed with the naked eye.

Since the hole is formed to penetrate the frame, the object 2 can move through the hole.

The first angle adjusting unit 12 is connected to one end of the housing 11 and can adjust the first angle of the housing 11. For example, the first angle adjusting unit 12 may include a first rail 121 and a first angle determining member 122.

The first rail 121 may be curved in an arc shape. For example, the first rail 121 may have an arc shape and an angle may be marked on the side so that the farther away from the center of the guide device 1, the closer the first rail 121 is to the pedicle. Meanwhile, the first rail 121 is not necessarily limited to an arc shape, and may be curved to have an elliptical curvature depending on the treatment method or type.

The first angle determining member 122 is connected to the housing 11 and moves on the first rail 121, thereby determining the first angle. The first angle determining member 122 is provided with a fixing screw, so that the housing 11 can be fixed by tightening the screw to have a preset first angle.

The second angle adjusting unit 13 is connected to the first angle adjusting unit 12 to adjust the second angle of the housing 11. For example, the second angle adjusting unit may include a second rail 131 and a second angle determining member 132.

The second rail 131 is connected to the center adjustment unit 14 and may be curved into an arc shape. For example, the second rail 131 may have an arc shape and an angle may be marked on the side so that the farther away from the center of the guide device 1, the closer the second rail 131 is to the pedicle. Meanwhile, the second rail 131 is not necessarily limited to an arc shape, and may be curved to have an elliptical curvature depending on the treatment method or type.

The second angle determining member 132 is connected to the first rail 121 and moves on the second rail 121 to determine the second angle. The second angle determining member 132 is provided with a fixing screw, so that the housing 11 can be fixed by tightening the screw to have a preset second angle.

Meanwhile, the first angle and the second angle may be defined in different planes. That is, since the direction in which the first rail 121 is curved and the direction in which the second rail 131 is curved are not parallel to each other, the angle of the housing 11 through which the object 2 is guided can be three-dimensionally controlled. With the guide device 1 holding the spine, when the guide device 1 is viewed from the opposite side (above) of the spine position, the first rail 121 and the second rail 131 may be perpendicular to each other, , Depending on the treatment method or type, it may be formed at a non-parallel angle.

The center adjustment unit 14 is connected to the second angle adjustment unit 13 to adjust the height of the housing 11. For example, the center adjustment unit 14 includes a first main member 141, a second main member 142, a first connection member 143, a height adjustment member 144, and a second connection member 145. It can be included.

The first main member 141 may be connected to the gripper 15.

The second main member 142 may be disposed in a separated state on one side of the first main member 141.

The first connection member 143 may connect the first main member 141 and the second main member 142.

The height adjustment member 144 can adjust the height of the second main member 142 relative to the first main member 141. That is, the height adjustment member 144 can ultimately adjust the height of the housing 11 by varying the relative distance between the second main member 142 and the first main member 141.

The second connecting member 145 extends through the second main member 142, and second angle adjusting parts 13 may be connected to both ends, respectively. The second connection member 145 can adjust the position of the second angle adjustment unit with respect to the center adjustment unit 14 by sliding with respect to the second main member 142.

The gripping part 15 is disposed on the lower side of the center adjusting part 14 and can grip the spine 3. For example, the grip part is formed in the form of a clip and can be fixed by clamping the spine from both sides. The gripper 15 can initially align the housing 11 by gripping the spinous process 31 of the vertebrae 3 . For example, when the gripper 15 is fixed to the spine by adding a part having the shape of the spinous process of the spine, the surgery to be placed at the correct position can be performed accurately according to plan.

FIG. 4 is a plan view showing a guide device according to an embodiment applied to the spine, and FIG. 5 is a side view showing a guide device according to an embodiment applied to the spine.

Referring to Figures 4 and 5, the housing is shown facing the pedicle so that the object 2 can be inserted into an appropriate position while the guide device 1 is applied to the spine. For example, the gripping portion 15 may be formed to conform to the spinous process 31 of the spine 3, and the width of the gripping portion 15 may be formed similar to the width of a general spinous process 31, The user can easily intuitively know where the guide device 1 will be fixed.

As described above, although the embodiments have been described with limited drawings, various modifications and variations can be made by those skilled in the art from the above description. For example, the described techniques may be performed in a different order than the described method, and/or components of the described structure, device, etc. may be combined or combined in a form different from the described method, or may be used with other components or equivalents. Appropriate results can be achieved even if replaced or substituted by .
