Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a handle and an intervertebral operating system. Background Art

[0002] With the aging of the population, spinal degenerative diseases with neck and shoulder pain and waist and leg pain as the main symptoms are seriously affecting people's work and life. Intervertebral fusion is currently one of the main methods for treating spinal degenerative diseases. Intervertebral fusion requires the implantation of a fusion device into the damaged intervertebral space. The fusion device can be deformed by compression to support the vertebral body. However, since most of the current fusion devices do not have the function of adjusting the fusion device, the installation and operation of the fusion device are inconvenient and cannot play a good supporting role. Summary of the invention

[0003] Based on this, the present invention aims to overcome the defects of the prior art and provide a handle and an intervertebral operating system that are easy to operate.

[0004] The technical solution is as follows:

[0005] A handle comprises a core rod, a middle sleeve and an outer sleeve, wherein the middle sleeve is sleeved outside the core rod, and the outer sleeve is sleeved outside the middle sleeve. The end of the middle sleeve is used to abut one end of a fusion device, and the core rod is used to pass through the fusion device and be connected to the other end of the fusion device. In an initial state, the outer sleeve is used to accommodate the fusion device. In an extruded state, the middle sleeve is used to move in a direction close to the fusion device, and the outer sleeve is used to move in a direction away from the fusion device.

[0006] The handle can be used to place the fusion device into the outer sleeve, and the end of the middle sleeve can be used to support one end of the fusion device, and the core rod can be used to pass through the fusion device and connected to the other end of the fusion device. Then, as the middle sleeve moves in a direction close to the fusion device and the outer sleeve moves in a direction away from the fusion device, the fusion device can gradually come out of the outer sleeve, and the middle sleeve can squeeze the fusion device, so that the fusion device is deformed under squeezing and supports the spine. When the fusion device is in the outer sleeve, the fusion device cannot be deformed due to the limitation of the outer sleeve. The fusion device will only be deformed when it comes out of the outer sleeve. The deformation of the fusion device can be controlled according to the moving distance of the middle sleeve, so the control of the fusion device is more precise and easy to operate.

[0007] In one embodiment, the handle further includes an adjusting rod, an outer control and an inner control, wherein the adjusting rod is used to be arranged on a side of the core rod away from the fusion device, one end of the outer control is connected to the outer sleeve, and the other end of the outer control is threadedly matched with one end of the adjusting rod, one end of the inner control is connected to the middle sleeve, and the other end of the inner control is threadedly matched with the other end of the adjusting rod, and the threads at both ends of the adjusting rod have opposite rotation directions.

[0008] In one embodiment, in the initial state, the front end of the outer sleeve extends through the front end of the middle sleeve and the core rod, the front end of the outer sleeve is used to accommodate the fusion device, the front end of the middle sleeve abuts one end of the fusion device, the rear end of the middle sleeve extends through the rear end of the outer sleeve, the inner control is connected to the rear end of the middle sleeve, the outer control is connected to the rear end of the outer sleeve, and the outer control is arranged on the side of the inner control away from the middle sleeve.

[0009] In one embodiment, the handle further comprises a gripping piece, the outer control piece and the inner control piece are both arranged inside the gripping piece, the outer sleeve and the adjusting rod are both passed through the gripping piece, a first slide rail is provided inside the gripping piece for slidingly cooperating with the outer control piece, a second slide rail is provided inside the gripping piece for slidingly cooperating with the inner control piece, and a mounting seat connected to the core rod is provided inside the gripping piece.

[0012] In the above-mentioned intervertebral operating system, the core rod is connected to the first segment, and the end of the middle sleeve is against the tail segment. When the middle sleeve moves in the opposite direction to the outer sleeve, that is, when the middle sleeve moves in the direction close to the main body, it will squeeze the main body. At this time, the distance between the two adjacent adjustment parts is reduced, so that the structural member is squeezed and bulges outward to support the vertebral body. By controlling the moving distance of the middle sleeve, the height of the outward bulge of the structural member can be controlled, which makes the operation more convenient. At the same time, since the main body is located in the outer sleeve in the initial state, the middle sleeve then moves in the direction close to the main body, and the outer sleeve and the middle sleeve are relatively separated, so that the main body gradually separates from the outer sleeve.

DETAILED DESCRIPTION

[0026] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0029] The “first” and “second” mentioned in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0030] like Figures 1 to 4As shown, one embodiment discloses a handle 100, including a core rod 110, a middle sleeve 120 and an outer sleeve 130, wherein the middle sleeve 120 is sleeved outside the core rod 110, and the outer sleeve 130 is sleeved outside the middle sleeve 120, and the end of the middle sleeve 120 is used to abut one end of the fusion device, and the core rod 110 is used to pass through the fusion device and be connected to the other end of the fusion device. In the initial state, the outer sleeve 130 is used to accommodate the fusion device, and in the extruded state, the middle sleeve 120 is used to move in a direction close to the fusion device, and the outer sleeve 130 is used to move in a direction away from the fusion device.

[0031] The handle 100 can be used to place the fusion device into the outer sleeve 130, and the end of the middle sleeve 120 can be used to resist one end of the fusion device, and the core rod 110 can be used to pass through the fusion device and connect with the other end of the fusion device. Then, as the middle sleeve 120 moves in a direction close to the fusion device, the outer sleeve 130 is used to move in a direction away from the fusion device, and the fusion device can gradually come out of the outer sleeve 130, and the middle sleeve 120 can squeeze the fusion device, so that the fusion device is deformed under squeezing and supports the spine. When the fusion device is in the outer sleeve 130, the fusion device cannot be deformed due to the limitation of the outer sleeve 130. The fusion device will only be deformed when it comes out of the outer sleeve 130. The deformation amount of the fusion device can be controlled according to the moving distance of the middle sleeve 120, so the control of the fusion device is more accurate and easy to operate.

[0032] In addition, since the fusion device is located in the outer sleeve 130 during the process of entering the spine, it will not touch other parts, which can prevent the fusion device from being contaminated and also ensure that the fusion device will not bump or scratch other parts.

[0033] Specifically, the handle 100 is used to operate the deformable fusion device that is squeezed. The middle sleeve 120 contacts one end of the fusion device, and the core rod 110 fixes the other end of the fusion device, so that the middle sleeve 120 squeezes the fusion device when approaching the fusion device, causing the fusion device to deform and support the vertebral body. At the same time, since the outer sleeve 130 is used to accommodate the fusion device, the outer sleeve 130 can be extended between the vertebral bodies so that the position of the fusion device is located between two adjacent vertebral bodies. At this time, the outer sleeve 130 moves in a direction away from the fusion device, so that the fusion device is separated from the outer sleeve 130, and then the fusion device is squeezed so that the fusion device supports the vertebral body. Therefore, the handle 100 can ensure that the fusion device enters between the vertebral bodies and deforms, and the protection effect of the fusion device is good.

[0034] In one embodiment, if Figure 1 , Figure 5 and Figure 6As shown, the handle 100 further includes an adjusting rod 140, an outer control 150 and an inner control 160. The adjusting rod 140 is used to be arranged on a side of the core rod 110 away from the fusion device. One end of the outer control 150 is connected to the outer sleeve 130, and the other end of the outer control 150 is threadedly matched with one end of the adjusting rod 140. One end of the inner control 160 is connected to the middle sleeve 120, and the other end of the inner control 160 is threadedly matched with the other end of the adjusting rod 140. The threads at both ends of the adjusting rod 140 have opposite rotation directions. Since the threads at both ends of the adjustment rod 140 rotate in opposite directions, the outer control 150 and the inner control 160 can be moved in opposite directions by rotating the adjustment rod 140. Since the outer control 150 drives the outer sleeve 130 to move and the inner control 160 drives the middle sleeve 120 to move, the fusion device can be separated from the outer sleeve 130 and the middle sleeve 120 to squeeze the fusion device. The above-mentioned method of controlling the movement of the outer sleeve 130 and the middle sleeve 120 by rotating the adjustment rod 140 can accurately control the movement distance of the outer sleeve 130 and the middle sleeve 120, thereby more accurately controlling the protruding height of the structural member 220, and at this time, it is more labor-saving to use the middle sleeve 120 to squeeze the fusion device, which is convenient to operate.

[0035] Alternatively, if Figure 5 and Figure 6 As shown, the outer control 150 includes an outer tube 151, an outer nut 152 and a first fixing member 153, and the inner control 160 includes an inner tube 161, an inner nut 162 and a second fixing member 163. The outer nut 152 and the first fixing member 153 are both arranged in the outer tube 151 and connected to the outer tube 151. The adjusting rod 140 passes through the outer nut 152 and is threadedly matched with the outer nut 152. The first fixing member 153 is sleeved on the outer sleeve 130. The inner nut 162 and the second fixing member 163 are arranged in the outer tube 151. 2 and the second fixing member 163 are both arranged in the internal tube 161 and connected to the internal tube 161, the adjusting rod 140 is penetrated by the internal nut 162 and threadedly matched with the internal nut 162, the second fixing member 163 is sleeved outside the middle sleeve 120, and the aperture of the external tube 151 is larger than the outer diameter of the internal tube 161. In the direction from the adjusting rod 140 to the core rod 110, the external nut 152, the internal nut 162, the second fixing member 163 and the first fixing member 153 are arranged in sequence.

[0036] In other embodiments, the middle sleeve 120 can be pushed by setting a cylinder or the like to move it toward the direction close to the fusion device; or a gear can be set, and the outer control 150 and the inner control 160 are respectively engaged with the two sides of the gear, and the gear is rotated manually or in cooperation with a motor transmission. When the gear rotates, the outer control 150 and the inner hole part move in different directions driven by the gear, and the outer sleeve 130 and the middle sleeve 120 can also achieve a movement effect of moving away from each other.

[0037] In one embodiment, if Figure 4 As shown, in the initial state, the front end 131 of the outer sleeve extends through the front end 121 of the middle sleeve and the core rod 110, the front end 131 of the outer sleeve is used to accommodate the fusion device, the front end 121 of the middle sleeve abuts one end of the fusion device, the rear end 122 of the middle sleeve extends through the rear end 132 of the outer sleeve, the inner control 160 is connected to the rear end 122 of the middle sleeve, the outer control 150 is connected to the rear end 132 of the outer sleeve, and the outer control 150 is arranged on the side of the inner control 160 away from the middle sleeve 120. The front end 131 of the outer sleeve extends through the front end 121 of the middle sleeve and the core rod 110, which can ensure that in the initial state, the fusion device is located in the outer sleeve 130, and the rear end 122 of the middle sleeve extends through the rear end 132 of the outer sleeve, and the outer control 150 is arranged on the side of the inner control 160 away from the middle sleeve 120, which can ensure that the outer control 150 and the inner control 160 will not interfere with each other during the movement process, thereby ensuring the use of the above-mentioned handle 100.

[0038] Specifically, Figure 4 As shown, the core rod 110 extends through the front end 121 of the middle sleeve. Since the front end 121 of the middle sleeve abuts one end of the fusion device, the core rod 110 passes through the fusion device and is connected to the other end of the fusion device, the core rod 110 needs to extend through the front end 121 of the middle sleeve.

[0039] In one embodiment, if Figure 1 and Figure 5 As shown, the handle 100 further includes a grip 170, the outer control 150 and the inner control 160 are both disposed in the grip 170, the outer sleeve 130 and the adjustment rod 140 are both penetrated by the grip 170, a first slide rail is disposed in the grip 170 for slidingly cooperating with the outer control 150, a second slide rail is disposed in the grip 170 for slidingly cooperating with the inner control 160, and a mounting seat 171 connected to the core rod 110 is disposed in the grip 170. The grip 170 can be convenient for operators to hold, the first slide rail and the second slide rail can prevent the outer control 150 and the inner control 160 from rotating in the circumferential direction, and at the same time make the outer control 150 and the inner control 160 more stable when moving, and the mounting seat 171 keeps the core rod 110 relatively still, so that the middle sleeve 120 can squeeze the fusion device by moving.

[0040] Optionally, both the external pipe 151 and the internal pipe 161 are provided with a clearance opening corresponding to the mounting seat 171. The clearance opening is used to prevent the external pipe 151 and the internal pipe 161 from interfering with the mounting seat 171 during movement.

[0041] Optionally, the outer surface of the gripping member 170 is wavy, so that the operator can hold it more tightly.

[0042] Alternatively, if Figure 1As shown, the handle 100 further includes a grip 180, which is disposed outside the gripping member 170 and connected to the adjusting rod 140, and the grip 180 and the adjusting rod 140 are perpendicular to each other. At this time, the grip 180 can be held and rotated to realize the rotation of the adjusting rod 140.

[0043] In one embodiment, if Figure 1 and Figure 7 As shown, the gripping member 170 is provided with an opening 172 opposite to the outer control 150, the opening 172 is arranged along the moving direction of the outer control 150, the gripping member 170 is provided with a scale at a position close to the opening 172, and the outer control is provided with a mark 173; or the gripping member is provided with an opening opposite to the inner control, the opening is arranged along the moving direction of the inner control, the gripping member is provided with a scale at a position close to the opening, and the inner control is provided with a mark. At this time, the length of the fusion device extending out of the outer sleeve 130 can be understood by the movement of the mark 173 and the comparison between the mark 173 and the scale, and the displacement of the middle sleeve 120 can be understood according to the displacement of the outer sleeve 130, and then the degree of compression of the fusion device by the middle sleeve 120 can be inferred, so that the operator can understand the degree of deformation of the fusion device located between the vertebral bodies during surgery.

[0044] like Figures 1 to 4 As shown, an embodiment discloses an intervertebral operating system, including a fusion device and a handle 100 as described above, the fusion device includes a main body 200, the main body 200 includes at least two adjustment parts 210 arranged at intervals, a structural member 220 is provided between two adjacent adjustment parts 210, the structural member 220 can bulge outward when squeezed to form a supporting plane 220a, the adjustment parts 210 located at both ends of the main body 200 are respectively the tail section 211 and the first section 212, in the initial state, the main body 200 is arranged in the outer sleeve 130, the end of the middle sleeve 120 abuts the tail section 211, and the core rod 110 passes through the main body 200 and is connected to the first section 212.

[0045] In the above intervertebral operating system, the core rod 110 is connected to the first segment 212, and the end of the middle sleeve 120 is against the tail segment 211. When the middle sleeve 120 moves in the opposite direction to the outer sleeve 130, that is, when the middle sleeve 120 moves in the direction close to the main body 200, the main body 200 is squeezed. At this time, the distance between the two adjacent adjustment parts 210 is reduced, so that the structural member 220 is squeezed and bulges outward to support the vertebral body. By controlling the moving distance of the middle sleeve 120, the The height of the outward protrusion of the structural member 220 is controlled, and the operation is more convenient. At the same time, because the main body 200 is located in the outer sleeve 130 in the initial state, and then the middle sleeve 120 moves in the direction close to the main body 200, the outer sleeve 130 and the middle sleeve 120 are relatively far away from each other, so that the main body 200 gradually separates from the outer sleeve 130. Only after the main body 200 leaves the outer sleeve 130 will the structural member 220 protrude outward under the squeezing of the middle sleeve 120, so the control of the deformation of the fusion device is more precise.

[0046] In addition, the structural member 220 is squeezed and bulges outward to form a support plane 220a to support the vertebral body. The plane structure can fit more closely with the vertebral body, provide a larger support area for the vertebral body, and provide a more stable support with a better support effect.

[0047] In one embodiment, if Figure 2 and Figure 4 As shown, the fusion device further includes a guide block 300, and a through hole 213 for the guide block 300 to pass through is provided on the adjustment portion 210. The guide block 300 is connected to the first section 212, and the core rod 110 passes through the main body 200 from one side of the tail section 211 and is threadedly connected to the guide block. The guide block 300 can guide the adjustment portion 210, so that when the main body 200 is squeezed by the middle sleeve 120, the adjustment portion 210 can move along the direction of the guide block, thereby preventing the deflection between different adjustment portions 210 during movement, thereby affecting the support effect of the main body 200.

[0048] In other embodiments, the core rod 110 may also be directly connected to the first section 212. For example, the end of the core rod 110 is an electromagnet, and the first section 212 is a magnetic material. The end of the core rod 110 extends to the first section 212 and is energized, so that the end of the core rod 110 and the first section 212 are adsorbed on each other, thereby realizing a magnetic connection between the core rod 110 and the first section 212.

[0049] In one embodiment, if Figure 3As shown, the inner hole of the middle sleeve 120 includes a first hole section and a second hole section 123, the first hole section matches the core rod 110, the second hole section 123 is used to accommodate the guide block, and the end of the second hole section 123 abuts against the tail section 211. At this time, when the middle sleeve 120 pushes the adjustment part 210 to squeeze the main body 200, the second hole section 123 of the middle sleeve 120 can be sleeved outside the guide block, and the guide block and the middle sleeve 120 are docked, so that the movement of the middle sleeve 120 is more accurate and stable, and the squeezing effect on the main body 200 is better.

[0050] Alternatively, if Figure 2 As shown, the structural member 220 includes a first connecting portion 221, a supporting portion 222 and a second connecting portion 223 which are connected in sequence. The connection between the first connecting portion 221 and the supporting portion 222 can be bent, and the connection between the second connecting portion 223 and the supporting portion 222 can be bent. The outer side of the supporting portion 222 is a supporting plane 220a. At this time, when the structural member 220 is squeezed, bending will occur between the first connecting portion 221 and the supporting portion 222, and between the second connecting portion 223 and the supporting portion 222, so that the supporting portion 222 moves outward to prevent the supporting portion 222 from being squeezed and bent, etc., thereby reducing the contact area between the supporting plane 220a and the vertebral body. Therefore, the structural member 220 set up as above can ensure that the supporting plane 220a has a better supporting effect on the vertebral body.

[0051] Alternatively, if Figure 2 As shown, the first connection part 221 includes two first plates 221a arranged at intervals, and the two ends of the first plates 221a are respectively connected to the adjustment part 210 and the support part 222, and the second connection part 223 includes two second plates 223a arranged at intervals, and the two ends of the second plates 223a are respectively connected to the adjustment part 210 and the support part 222. At this time, the shapes of the first connection part 221, the second connection part 223 and the support part 222 are different. When the structural member 220 is squeezed, the connection between the first connection part 221 and the support part 222, and the connection between the second connection part 223 and the support part 222 are more likely to deform, ensuring that the support part 222 can bulge outward and the support part 222 does not bend and deform, thereby ensuring that the support plane 220a has a better support effect on the vertebral body.

[0052] Alternatively, if Figure 2As shown, the first extension part 222a and the second extension part 222b are respectively provided on both sides of the support part 222, the first extension part 222a extends between the two first plates 221a and is spaced apart from the first plates 221a, the second extension part 222b extends between the two second plates 223a and is spaced apart from the second plates 223a, and the first extension part 222a and the second extension part 222b are arranged flush with the support part 222. In the above structure, the first extension part 222a and the second extension part 222b expand the area of ​​the support plane 220a, so that the support of the vertebral body is more stable and the support effect is better.

[0053] In one embodiment, if Figure 2 As shown, there are two structural members 220 between two adjacent adjustment parts 210, and the two structural members 220 are respectively a first structural member 220b and a second structural member 220c, and the first structural member 220b and the second structural member 220c are arranged at intervals in the up-down direction, and both the first structural member 220b and the second structural member 220c are protruded in a relatively distant direction. When the two adjacent adjustment parts 210 are close to each other, the first structural member 220b and the second structural member 220c are squeezed, and the supporting part 222 of the first structural member 220b and the supporting part 222 of the second structural member 220c are protruded in a relatively distant direction, at which time the deformation of the main body 200 is larger, the contact with the two adjacent vertebrae is tighter, and the supporting effect is better.

[0054] In other embodiments, there may be one structural member 220 between two adjacent adjustment parts 210. In this case, only one side of the main body 200 protrudes outward, and the other side serves as a base, which can also support the vertebral body.

[0055] Optionally, the connection between the first connection part 221 and the support part 222, and the connection between the second connection part 223 and the support part 222 are both provided with cutouts, and the cutout on the first structural member 220b is provided on the side of the first structural member 220b close to the second structural member 220c, and the cutout on the second structural member 220c is provided on the side of the second structural member 220c close to the first structural member 220b. When the cutout is provided on one side of the structural member 220, the strengths of the two sides of the structural member 220 are different, so that the structural member 220 bends toward the side with the cutout when being squeezed, and the above-mentioned arrangement of the cutouts on the first structural member 220b and the second structural member 220c can ensure that when two adjacent adjustment parts 210 approach each other, the support part 222 of the first structural member 220b and the support part 222 of the second structural member 220c move in a relatively distant direction to achieve support for two adjacent vertebral bodies.

[0056] In other embodiments, the connection between the first connection portion 221 and the support portion 222 and the connection between the second connection portion 223 and the support portion 222 may also be provided with a fold, which is a depression provided on the structural member 220, so that the structural member 220 can be bent along the fold when being squeezed.

[0057] Optionally, in the arrangement direction of the adjusting member, the length of the first connecting portion 221 is equal to the length of the second connecting portion 223. At this time, when the structural member 220 is squeezed, the supporting portion 222 can contact the vertebral body in a horizontal posture, increasing the contact area between the supporting plane 220a and the vertebral body and improving the stability of the vertebral body support.

[0058] Optionally, the first connection part 221 and the second connection part 223 are made of the same material, so as to ensure that when the structural member 220 is squeezed, the deformation of both sides of the support part 222 is consistent, so that the support part 222 can finally contact the vertebral body in a horizontal posture, increase the contact area between the support part 222 and the vertebral body, and improve the support effect on the vertebral body.

[0059] Optionally, when the number of the adjusting parts 210 is at least three, two adjacent adjusting parts 210 form a group of units, and after the structural members 220 in different groups of units are squeezed, the raised support planes 220a thereof may be parallel to each other or non-parallel to each other. The raised support planes 220a in different groups of units may be adjusted according to actual conditions to improve the support effect.

[0060] In one embodiment, if Figure 2 As shown, the first height limiting member 214 and the second height limiting member 215 are respectively provided on two adjacent adjustment parts 210, and the first height limiting member and the second height limiting member are arranged opposite to each other along the arrangement direction of the adjustment parts 210. By providing the first height limiting member 214 and the second height limiting member 215, after the first adjustment part 210 and the second adjustment part 210 are close to each other at one end distance, the first height limiting member 214 and the second height limiting member 215 abut against each other, so that the first adjustment part 210 and the second adjustment part 210 cannot continue to approach each other, and the support part 222 cannot continue to bulge. Therefore, the above structure can limit the displacement of the support part 222 to prevent the support part 222 from exerting too much pressure on the vertebral body. In addition, as the main body 200 leaves the outer sleeve 130, the adjacent structural members 220 are separated from the outer sleeve 130 in turn and deformed under the action of extrusion. Since the first height limiter 214 and the second height limiter 215 are provided, the support portion 222 protrudes to a predetermined height and then stops, and then the next structural member 220 protrudes and deforms, so that the deformation of different structural members 220 in the main body 200 proceeds in an orderly manner, and the protrusion heights of different structural members 220 remain consistent, thereby better supporting the vertebral body.

[0061] Optionally, the main body 200 has an undeformed state and an extruded deformed state. In the undeformed state, the main body 200 is a hollow rectangular parallelepiped structure; in the extruded deformed state, the distance between two adjacent adjustment parts 210 is reduced, and the structural member 220 protrudes outward to form a support plane 220a. When the main body 200 is placed between two vertebral bodies, the main body 200 can be placed in a relatively stable manner without rotation, ensuring that when the structural member 220 protrudes, the support plane 220a can better support the vertebral body and increase the contact area with the vertebral body. In addition, the hollow rectangular parallelepiped structure of the main body 200 is conducive to the insertion and fixation of tools, and facilitates the adjustment of the distance between the two adjustment parts 210.

[0062] In other embodiments, the main body 200 may also be tubular.

[0063] Optionally, the shape of the inner hole at one end of the outer sleeve 130 close to the main body 200 matches the shape of the main body 200. In this case, the main body 200 can be placed stably and conveniently.

[0064] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0065] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
