As shown in fig. 1 to 8, basically, the perspective four-point spinal split-blade carrier of the present invention includes a fixing mechanism 1, a pair of sliding mechanisms 2, and two pairs of supporting pads 3.

The fixing mechanism 1 includes a substrate unit 11, and as shown in fig. 1 and 2, the substrate unit 11 includes a pair of sub-boards 111 disposed opposite to each other and spaced apart from each other. Two ends of the pair of sub-plates 111 are oppositely combined with two pairs of joint seats 12, and each pair of joint seats 12 is provided with a pair of interfaces 121 in an X-axis direction, so that the two ends of each pair of fixed rails 13 are correspondingly inserted and connected, and the fixing mechanism 1 forms a rectangular frame.

Referring to fig. 1 to 3 and 6 to 7, the bottom of each of the joint seats 12 has a bottom groove 122 for mounting a supporting block 123, so that the interface 121 for inserting one end of the fixed rail 13 is formed above the supporting block 123 in the joint seat 12.

One end of each fixed rail 13 is sleeved into one end tenon 131 and inserted into the corresponding interface 121. In order to prevent the fixed rails 13 from being separated from the corresponding connecting seats 12, a first locking structure is provided therebetween, the first locking structure includes a first inner pin hole 132 formed in each fixed rail 13 and the end tenon 131 therein and aligned with each other in a Y-axis direction, a first outer pin hole 124 formed in the connecting seat 12 at the position of the interface 121 and corresponding to the first inner pin hole 132, and a first locking member 125, such as a pin, locked in the first inner pin hole 132 and the first outer pin hole 124, so that the fixed rail 13 and the connecting seat 12 cannot be separated in the X-axis direction.

Another embodiment of the first latch structure comprises that each of the fixed rails 13 and the end tenons 131 therein are respectively provided with a second inner pin hole 133 aligned with each other in a Z-axis direction, the supporting block 123 is provided with a through hole 123a corresponding to the second inner pin hole 133, and the substrate unit 11, for example, the corresponding daughter board 111 is provided with a through hole 112; a second latch member 113 is passed through the through hole 112 and the through hole 123a and latched in the second inner pin holes 133, so that the fixed rail 13 and the joint base 12 are not disengaged in the X-axis direction.

The second latch 113 is implemented as a screw having a male thread, and thus the second inner pin hole 133 of the supporting block 123 is correspondingly provided with a female thread, so that the two can be locked and connected in a screw manner.

Furthermore, in order to prevent the supporting block 123 from being detached from the engaging seat 12, a second latching structure is further included therebetween, the second latching structure includes a second outer pin hole 126 and a third inner pin hole 123b, which are aligned with each other, and are correspondingly formed in the Y-axis direction of the engaging seat 12 and the supporting block 123, and a third latching member 127, for example, a latch, is latched in the second outer pin hole 126 and the third inner pin hole 123b, so that the supporting block 123 can be stably disposed in each of the engaging seats 12 without being detached in the X-axis direction.

In addition, the substrate unit 11, for example, the combination of each sub-board 111 and the corresponding joint seat 12, includes a third latch structure, which opens a third inner pin hole 128 and a bottom hole 114 aligned with each other in the Z-axis direction at each joint seat 12 and the corresponding sub-board 111; then, a fourth latch 115 is passed through the bottom hole 114 and latched in the third inner pin holes 128, so that each of the engaging seats 12 and the correspondingly coupled sub-plate 111 are not disengaged in the Z-axis direction as well.

The fourth latch 115 is implemented as a screw having a male thread, so that the third inner pin hole 128 of the joint base 12 is correspondingly provided with a female thread, so that the two can be locked and connected in a screw manner.

Further, in another embodiment, the substrate unit 11 is a rectangular plate. The four corners of the rectangular plate are opposite and spaced to combine two pairs of joint seats 12 as shown in the foregoing embodiment, and the pair of interfaces 121 opened on each pair of joint seats 12 in the X-axis direction are used for the corresponding insertion and connection of the two end portions of the fixed rail 13, so that the fixing mechanism 1 forms a rectangular frame. Please refer to the foregoing embodiments, and detailed descriptions thereof are omitted herein for the combination manner of each of the fixed rails 13 and the pair of engaging seats 12 on both sides and each of the engaging seats 12 and the substrate unit 11.

The pair of sliding mechanisms 2 are made of a non-metallic material, and are disposed at intervals and slidably mounted on the pair of fixed rails 13 so as to adjust the distance between the pair of sliding mechanisms 2.

Referring to fig. 1 to 4 and 8, each of the sliding mechanisms 2 includes a sliding plate 21 and a pair of clamps 22. The sliding plate 21 has two elongated slots 211 formed at two ends of the Y-axis direction, a plate hole 212 is formed inside each slot 211, and a pair of elongated adjustment slots 213 are formed at two sides of the sliding plate 21.

Each of the clamps 22 has a clamping opening 221 facing the slot 211 for the fixed rail 13 and the slot 211 of the sliding plate 21 to be inserted into, and a first screw hole 222 on the top surface of each clamp 22 is screwed with a first knob 223, so that the bottom of the first knob 223 abuts against the sliding plate 21 and further forms a fastening location for the fixed rail 13. Therefore, by unscrewing or screwing the first knob 223, each of the clamps 22 can be slid and positioned along the X-axis direction on the corresponding fixed rail 13.

A tenon 223a with a size smaller than that of the upper thread section protrudes from the bottom end of the first knob 223, and the tenon 223a is received in the hole 212. Referring to fig. 1 and 8, to move each sliding mechanism 2, a user, such as a medical staff, only needs to rotate the first knobs 223 on two sides of each sliding mechanism 2 in opposite directions, so that the first knobs 223 move upwards due to unscrewing, and the tenons 223a are still located in the plate holes 212, so that each clamp 22 is not separated from the sliding plate 21, thereby preventing the clamps 22 from being possibly contaminated due to falling on the ground.

Further, the width of each slot 211 of the sliding plate 21 is greater than the width of the clamp 22, so that when the first knob 223 is in the unscrewed state, the sliding plate 21 can be adjusted by an offset angle of +5 degrees to-5 degrees in the Y-axis direction relative to the clamp 22, so as to meet the posture requirement of the patient with lateral curvature of spine.

The two pairs of supporting pads 3 are mounted on the pair of sliding mechanisms 2 for supporting the patient. Each pair of support pads 3 is oppositely mounted on the pair of long adjustment grooves 213 on both sides of each sliding plate 21, and for convenience of description, only one support pad 3 is disclosed as a representative.

Each of the support pads 3 is also made of a non-metal material, and includes a moving frame 31 and a pad 32. The bottom of the moving frame 31 is protruded with a limiting block 311 sleeved in the corresponding long-shaped adjusting groove 213, wherein the width of the limiting block 311 is smaller than the long-shaped adjusting groove 213, so that the supporting pad 3 can be adjusted by an offset angle of +10 degrees to-10 degrees in the Y-axis direction relative to the sliding plate 21, thereby satisfying the posture requirement of the patient suffering from lateral bending of the spine.

The bottom of the movable frame 31 is provided with a second screw hole 312 aligned with the long adjustment slot 213 in the Z-axis direction, so that a second knob 33 can pass through the long adjustment slot 213 and be screwed into the second screw hole 312, so that the movable frame 31 and the second knob 33 together clamp the sliding plate 21 to form a tight positioning. Therefore, by loosening or tightening the second knob 33, the support pads 3 can be slid and positioned on the sliding plate 21 along the Y-axis direction.

Further, the top surface of the movable frame 31 is inwardly provided with an inclined surface 313 having a predetermined inclination angle, and the inclined surface 313 is preferably inclined at an angle of 10 to 20 degrees, and more preferably at an angle of 15 degrees.

In addition, the inclined surface 313 is further connected to a support plate 314, and the pad 32 is connected to the support plate 314, so that the pad 32 has an inward inclination angle of a fixed pattern relative to the sliding plate 21.

Furthermore, in order to consider that the second knob 33 is located on the bottom surface of the sliding plate 21 and is not beneficial to operation, the second knob 33 is sleeved with a rotating handle 34 capable of forming linkage with the second knob 33, so that the second knob 33 can be synchronously driven to perform loosening or screwing operation by rotating the rotating handle 34, so as to conveniently adjust the distance between each pair of supporting pads 3. A non-metal spacer 35 is further sleeved between the rotating handle 34 and the sliding plate 21 to prevent the rotating handle 34 from clinging to the sliding plate 21, and the space is increased by the spacer 35 to improve the operability.

The fixing mechanism 1 is a rectangular non-metal frame body for X-ray perspective, the substrate unit 11, the pair of engaging seats 12 and the pair of fixing rails 13 are made of carbon fiber, glass fiber or bakelite (bakelite), and the first latch structure, the second latch structure and the third latch structure are made of plastic pins, glass fiber pins or plastic screws.

Please refer to fig. 1, which shows a perspective view of the fixing mechanism 1, the pair of sliding mechanisms 2 and the two pairs of supporting pads 3 assembled according to the foregoing description; and figure 5 is a top view of figure 1. The fixing mechanism 1 fixes two pairs of oppositely disposed engaging seats 12 to the substrate 1, such as two corresponding ends of a pair of sub-boards 111, and combines the pair of fixing rails 13 between the two pairs of engaging seats 12.

The two end portions of the sliding plate are straddled over the pair of fixed rails 13 by each sliding mechanism 2, the pair of clamps 22 are respectively sleeved on the two end portions of the sliding plate 21 and the pair of fixed rails 13, and the pair of clamps 22 and the sliding plate 21 slide in the X-axis direction on the pair of fixed rails 13 by loosening or screwing the first knob 223 of the pair of clamps 22, so that the distance between the pair of sliding mechanisms 2 and the two pairs of supporting pads 3 mounted on the two pairs of sliding mechanisms 2 is adjusted to adapt to different height body types.

The pair of support pads 3 move the pair of moving frames 31 and the cushion 32 mounted thereon in the Y-axis direction on the sliding plate 21 by loosening or tightening the second knob 33 or the knob 34 of each moving frame 31, so as to adjust the spacing distance between each pair of support pads 3 to adapt to different body types. In addition, the pad body 32 of each support pad 3 provides a comfortable prone position for the patient.

Referring to fig. 1 again, since the fixing mechanism 1, the pair of sliding mechanisms 2 and the two pairs of supporting pads 3 are made of non-metallic materials, there is no blocking or refraction caused by any metal component during X-ray spinal fluoroscopy, so that 3D radiography is actually realized.

As shown in fig. 9, it is a top view of the sliding plate 21 and the supporting pad 3 for performing the angle fine adjustment operation, so as to further illustrate that the perspective type four-point type spinal open knife holder of the present invention can fully cope with the body type of the patient, such as height, slimness, or lateral curvature of the spine, so as to facilitate the spinal surgery.

As shown in fig. 10, the perspective type four-point spine surgical knife rest shown in fig. 1 is directly placed on a bed plate 41 of a perspective type operating table 4. On the other hand, as shown in fig. 11, the patient lies on the two pairs of supporting pads 3 of the perspective four-point spine open frame, which is helpful for the physical image, such as X-ray photography, so that the correct diagnosis and operation can be performed during the spine operation.

Therefore, through the implementation of the present invention, the enhanced efficacy lies in that the pair of fixing rails of the fixing mechanism of the perspective four-point spine open knife rest, the pair of clamps of the sliding mechanism and the two pairs of supporting pads are all located on both sides of the spine and have a larger distance when performing the spine surgery, so that the perspective four-point spine open knife rest is collocated with the perspective operating table, and when performing the spine fluoroscopy, there is no obstruction of any metal component, and because the substrate is made of a plate material that can be used for X-ray perspective, it is helpful for X-ray perspective radiography, so that when performing the spine surgery, it is able to obtain the correct diagnosis image in real time to facilitate the performance of the surgery. Furthermore, the perspective four-point type spine knife rest has the advantage of light weight through humanized design, so that users, such as medical staff, can easily carry the spine knife rest, and spine surgery can be conveniently performed.

The present invention is directed to a preferred embodiment, and any modifications or equivalent substitutions easily accomplished by those skilled in the art are intended to fall within the scope of the present invention, which is defined by the following claims.
