Description

Technical Field

[0001] The invention belongs to the technical field of bone graft shaping, and more specifically, particularly relates to a bone graft shaping device. Background Art

[0002] Costal cartilage is a transparent cartilage located between the ribs and the sternum. It is elastic and tough, and together with the ribs, it forms the thorax, supporting and protecting the organs in the thoracic cavity. Costal cartilage, as an important cartilage tissue in the human body, has multiple functions, including support, protection, and auxiliary breathing, as well as serving as a source of autologous cartilage for reconstruction of articular cartilage surfaces. Costal cartilage is often used as a rhinoplasty stent material in rhinoplasty surgery due to its hardness, elasticity, abundant tissue volume, good biocompatibility, and natural and beautiful effects. It can provide stable support and meet the needs of personalized nose shaping. Costal cartilage, as an autologous tissue, is not prone to rejection after implantation, thereby reducing the occurrence of rejection and complications.

[0003] Based on the above, the inventors have discovered the following problems: when making a rhinoplasty stent, the doctor usually cuts an appropriate amount of costal cartilage from the 6th or 7th rib on the right side of the patient. The cut costal cartilage will undergo fine processing, including removing surface soft tissue, blood, etc. to ensure its quality and purity. Then, the doctor will use a bone knife to cut the cut costal cartilage. Since multiple rhinoplasty stents are sometimes required, the doctor will first slice the costal cartilage and then carve it. However, slicing the costal cartilage with a handheld bone knife is relatively laborious and may result in cutting errors.

[0004] Therefore, in view of this, research and improvement are conducted on the existing structure and defects, and a bone graft reshaper is provided in order to achieve a more practical purpose. Summary of the invention

[0037] Example:

[0038] As attached Figure 1 To Attachment Figure 8 As shown:

[0039] The present invention provides a bone graft orthopedic device, comprising an installation frame 1, wherein a collecting component is arranged in the installation frame 1, a mounting plate 3 is installed on the outer wall of one side of the installation frame 1, a connecting rod 5 is installed on the mounting plate 3 through a moving mechanism 4, a first arc plate 6 is installed on one end of the connecting rod 5, a mounting frame 7 is installed on the surface of the connecting rod 5, a connecting plate 8 is installed on the inner wall of the mounting frame 7, a threaded hole 9 is installed on the surface of the installation frame 1, a screw 10 is installed in the threaded hole 9, an adjusting hand wheel 11 is installed on one end of the screw 10, a limiting rod 12 is rotatably installed on the end of the screw 10 away from the adjusting hand wheel 11, a limiting hole 13 is provided on the surface of the connecting plate 8, the limiting rod 12 is located in the limiting hole 13, a second arc plate 14 is installed on the end of the limiting rod 12 away from the screw 10, and an ultrasonic bone knife 15 is clamped between the first arc plate 6 and the second arc plate 14.

[0040] Through the coordinated use of the first curved plate 6, the mounting frame 7, the connecting plate 8, the threaded hole 9, the screw 10, the adjusting hand wheel 11, the limiting rod 12, the limiting hole 13 and the second curved plate 14, when the rib cartilage needs to be sliced, it is only necessary to place the ultrasonic bone knife 15 between the first curved plate 6 and the second curved plate 14, and then rotate the adjusting hand wheel 11. The rotation of the adjusting hand wheel 11 will drive the screw 10 to rotate. The rotation of the screw 10 will move back and forth under the action of the threaded hole 9. The movement of the screw 10 will drive the limiting rod 12 to move. Since the screw 10 and the limiting rod 12 are rotatably connected, the limiting hole 13 can move the limiting rod 12. The limit rod 12 will not rotate when it moves, and the movement of the limit rod 12 will drive the second arc plate 14 to move, thereby clamping the ultrasonic bone knife 15, and then start the ultrasonic bone knife 15, draw a cutting line on the rib cartilage, and then place the rib cartilage on the collection component, align the cutting line of the rib cartilage with the blade of the ultrasonic bone knife 15, and then push the rib cartilage to slice the rib cartilage. Compared with holding it with one hand, it is easier to slice the rib cartilage. After slicing, the adjustment hand wheel 11 can be rotated in the opposite direction to release the clamping of the ultrasonic bone knife 15, and then the ultrasonic bone knife 15 can be held to carve the rib cartilage. Through the above design, the rib cartilage can be easily sliced, and the accuracy of slicing is also improved, which improves practicality.

[0041] Wherein, first rubber pads 16 are installed on the surfaces of the first curved plate 6 and the second curved plate 14 .

[0042] By using the first rubber pad 16 , the friction force for clamping the ultrasonic osteotome 15 can be increased.

[0043] Among them, the collecting component includes a water collecting box 201 and a collecting plate 202, the bottom end surface of the water collecting box 201 is evenly distributed with four guide pillars 203, the bottom of the collecting plate 202 is evenly distributed with four guide sleeves 204, the guide pillars 203 are located in the guide sleeves 204, and a certain distance is left between the four sides of the collecting plate 202 and the four walls of the water collecting box 201. The collecting plate 202 includes a plane area 20201 and a slope area 20202, the plane area 20201 is located at the center of the water collecting box 201, and the slope area 20202 is located on both sides of the plane area 20201, and the surface of the plane area 20201 is provided with a groove 20203 matching the blade head of the ultrasonic bone knife 15.

[0044] Through the coordinated use of the water collecting box 201, the collecting plate 202, the guide column 203 and the guide sleeve 204, the ultrasonic bone knife 15 will spray water while in use, and the water and bone residue will fall onto the collecting plate 202. The flat area 20201 can be used as a cutting platform for the rib cartilage, and the slot 20203 can extend the blade of the ultrasonic bone knife 15 to the bottom of the collecting plate 202, so as to facilitate the cutting of the rib cartilage. The inclined area 20202 can guide the water, and the water flows into the water collecting box 201 through the gap between the collecting plate 202 and the water collecting box 201 for collection. When the collecting component needs to be cleaned, the ultrasonic bone knife 15 can be moved upward or removed by the moving mechanism 4, and then the collecting component can be removed from the mounting frame 1, and then the collecting plate 202 can be lifted up to release the restraint between the guide column 203 and the guide sleeve 204, and then the bone residue on the collecting plate 202 and the water in the water collecting box 201 can be cleaned. Through the above design, the water and bone residues produced by plastic surgery can be effectively collected.

[0045] Among them, the moving mechanism 4 includes a group of bearing seats 401 installed on the surfaces of the upper and lower ends of the mounting plate 3, a screw rod 402 is installed in the bearing seat 401, a rotating hand wheel 403 is installed at one end of the screw rod 402, the screw rod 402 passes through the moving block 404, and also includes a limiting groove 405 opened on the surface of the mounting plate 3, the moving block 404 is located in the limiting groove 405, and the moving block 404 is connected to the connecting rod 5 through a detachable mechanism 17.

[0046] Through the coordinated use of the bearing seat 401, the screw rod 402, the rotating hand wheel 403, the moving block 404 and the limiting groove 405, when the rib cartilage needs to be carved, the ultrasonic osteotome 15 is first removed, and the rotating hand wheel 403 can be rotated. When the rotating hand wheel 403 rotates, the screw rod 402 is driven to rotate, and the screw rod 402 rotates to drive the moving block 404 to move. The movement of the moving block 404 drives the connecting rod 5 to move. When moving, the limiting groove 405 limits the moving block 404 to prevent it from rotating. Through the above design, the connecting rod 5 can be easily moved to the top to avoid obstruction when carving the rib cartilage.

[0047] Among them, the detachable mechanism 17 includes a slot 1701 opened on the surface of the moving block 404 and a block 1702 installed on the surface of the connecting rod 5, the block 1702 is located in the slot 1701, and the slot 1701 leaves a certain distance from the bottom of the moving block 404, and the block 1702 matches the slot 1701.

[0049] Therein, four mounting members 18 are evenly mounted on the surface of the mounting frame 1 , and mounting holes 19 are mounted on the surfaces of the mounting members 18 .

[0050] By using the mounting member 18 and the mounting hole 19, it can be conveniently fixed on a mounting table with mounting holes during use, thereby improving stability.

[0051] Wherein, a lighting lamp 20 is installed at the bottom of the connecting rod 5.

[0052] By using the illumination lamp 20, the costal cartilage can be illuminated when being carved.

[0053] The mounting plate 3 and the mounting frame 1 are connected via a first bolt 21 .

[0054] By using the first bolts 21 , the mounting plate 3 can be easily replaced.

[0055] The bearing seat 401 and the mounting plate 3 are connected via a second bolt 22 .

[0056] By using the second bolt 22 , the screw rod 10 and the bearing seat 401 can be easily replaced.

[0057] The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art.
