[0002] In costal cartilage rhinoplasty, small granular cartilage (cartilage particles with a diameter of less than 1mm) are often used to shape the nose tip and raise the bridge of the nose. Costal cartilage is located between the ribs and the sternum, and removing a small part of it will not affect the stability of the entire thorax, so it is widely used.

[0003] At present, the costal cartilage is generally harvested from a small section of the sixth, seventh, and eighth ribs, and is harvested according to the individual's surgical replacement part. After harvesting, it is cut and crushed with traditional instrument knives.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0043] Furthermore, in the description of the present application, unless otherwise specified, “plurality” means two or more.

[0044] In surgeries where costal cartilage is used as a substitute for elastic cartilage, cutting and crushing the costal cartilage is an essential surgical step. However, the operation process of traditional cutting and crushing tools is repetitive and time-consuming, and can easily cause fatigue to the physician. To solve the above problems, the present invention uses a costal cartilage cutting and crushing device to effectively and quickly crush the costal cartilage through cutting force to achieve surgical shaping standards.

[0045] like Figures 1 to 5As shown, an embodiment of the present application provides a rib cartilage cutting and crushing device, comprising a detachably connected shell 1 and a cartilage placement portion 2, the cavity of the shell 1 extending from its top to the bottom sequentially comprising a pressing cavity 11, a cleaning cavity 12 and a transition cavity 13; a cutting assembly 3 is provided in the shell 1, the cutting assembly 3 comprises a connected knife body 31 and a cutting portion 32, the knife body 31 extends from the pressing cavity 11 into the cleaning cavity 12, the cutting portion 32 is arranged in the cleaning cavity 12, a cleaning portion 4 is provided in the cleaning cavity 12, the cleaning portion 4 can rotate relative to the cleaning cavity 12, the cleaning portion 4 sequentially comprises a connected knife body through groove 5 and a cutting portion through groove 6 from top to bottom; a rotating pressing portion 7 is provided at one end of the cutting assembly 3 away from the cartilage placement portion 2, and an elastic member 8 cooperating with the rotating pressing portion 7 is provided on the cavity wall of the pressing cavity 11. The device described in the present invention rotates and presses the rotating pressing part 7 so that the cutting part 32 can pass through the transition cavity 13 and then enter the cartilage placement part 2. The costal cartilage of the cartilage placement part 2 can be effectively and quickly crushed by the cutting force of the cutting part 32, and can effectively reduce the doctor's operation time during the operation and reduce the fatigue caused by repeated operations.

[0046] In the rib cartilage cutting and crushing device provided in the present application, Figure 1 As shown, the shell 1 includes a hollow cavity, and the pressing cavity 11, the cleaning cavity 12 and the transition cavity 13 are connected in sequence to form the cavity of the shell 1. The cartilage placement part 2 includes a cartilage accommodating cavity for accommodating cartilage, and the cartilage accommodating cavity is connected to the transition cavity 13. The shell 1 and the cartilage placement part 2 are detachably connected to facilitate the loading and removal of cartilage after cutting. The shape of the cartilage placement part 2 can be, for example, a cylindrical shape that matches the shell 1, and the detachable connection method of the cartilage placement part 2 and the shell 1 can be, for example, a threaded connection, and can also be further fixed by screws.

[0047] In the rib cartilage cutting and crushing device provided in the present application, Figure 4 As shown, the cutter row body 31 includes a plurality of cutters arranged side by side and at intervals, such as Figure 1 As shown, the cutter row body through slot 5 includes a cutter row through slot 51 that matches each of the cutters one by one. Since the cleaning portion 4 can rotate relative to the cleaning chamber 12, the cutter row body 31 can also move along the height direction of the shell 1 through each cutter row through slot 51. Therefore, when pressed by the rotary pressing portion 7, the cutter row body 31 can move relative to the cleaning portion 4 toward the cartilage placement portion 2 through each cutter row through slot 51. When the rotary pressing portion 7 rotates clockwise or counterclockwise, the rotary pressing portion 7 can drive the cutter row body 31 to rotate (for example, it can rotate 360 ​​degrees), and the cutter row body 31 also drives the cleaning portion 4 to rotate.

[0048] In the rib cartilage cutting and crushing device provided in the present application, the cleaning part 4 is a solid structure. As needed, a plurality of knife row slots 51 are formed by extending downward from the top of the cleaning part 4 for a certain distance, and then the ends of the plurality of knife row slots 51 continue to extend downward to the bottom to form a cutting part slot 6 that matches the cutting part 32. In a specific embodiment, the ratio of the height of the knife row slot 5 to the height of the cutting part slot 6 can be 1:9 to 3:7, 1:9 to 2:8, or 2:8 to 3:7. More preferably, it is 2:8. The outer periphery of the cleaning part 4 also has a protruding block to fix the cleaning part 4 in the cleaning chamber 12 in the housing 1, and it can rotate with the cutting assembly 3.

[0049] In the rib cartilage cutting and crushing device provided in the present application, Figure 4 As shown, the cutting portion 32 includes a plurality of first cutting edges 321 that are consistent with the extension direction of each of the row of cutters and a second cutting edge 322 that is perpendicular to the extension direction of each of the first cutting edges 321. The first cutting edges 321 and the second cutting edges 322 are staggered and vertically distributed to form a tic-tac-toe-shaped cutting portion 32. The plurality of first cutting edges 321 can be respectively regarded as the row of cutters further extending toward the cartilage placement portion 2, so the cutting portion passing groove 6 on the cleaning portion 4 corresponding to the cutting portion 32 does not affect the passage of the row of cutter bodies 31. However, since the cutting portion 32 also has a second cutting edge 322, the cutting portion 32 cannot pass through the row of cutter bodies passing groove 5 on the cleaning portion 4. The design of the cleaning part 4 is that after the hose is cut and crushed, the costal cartilage contains tissue mucus, which will stick to the cutting part 32. When the hand is released, the elastic force of the elastic part 8 will cause the cutting assembly 3 to move away from the cartilage placement part 2. In this way, after the cutting part 32 rebounds, the cleaning part 4 can push the costal cartilage stuck on the cutting part 32 down and return it to the cartilage placement part 2 through the action between the cutting part 32 and the cutting part through the groove 6.

[0050] In the rib cartilage cutting and crushing device provided in the present application, the slot width of the row of cutters through the slot 51 matches the thickness of the row of cutters, and matching here means that the slot width of the row of cutters through the slot 51 is slightly larger than the thickness of the row of cutters. In this way, the row of cutters can pass through the row of cutters through the slot 51 smoothly, and the gap will not be too large. In a specific embodiment, the slot width of the row of cutters through the slot 51 is 0.5mm to 2mm, 0.5mm to 1mm, 1mm to 1.5mm, or 1.5mm to 2mm larger than the thickness of the row of cutters.

[0051] In the costal cartilage cutting and crushing device provided in the present application, the slot width of the cutting portion through the slot 6 matches the thickness of the first cutting blade 321 or the second cutting blade 322, and matching here means that the slot width of the cutting portion through the slot 6 is slightly larger than the thickness of the first cutting blade 321 or the second cutting blade 322. In a specific embodiment, the thickness of the first cutting blade 321 or the second cutting blade 322 can be equal. It should be explained that the slot width of the cutting portion through the slot 6 here includes the longitudinal slot width, and its extension direction is consistent with the slot width of the row of cutters through the slot 51, that is, the width of the longitudinal slot width is slightly larger than the blade thickness of the first cutting blade 321. It also includes a transverse slot width perpendicular to the longitudinal slot width, that is, the width of the transverse slot width is slightly larger than the blade thickness of the second cutting blade 322. In this way, the cutting portion 32 can pass through the cutting portion through the slot 6 smoothly, and the gap will not be too large, which is convenient for the subsequent cleaning of tissue mucus on the costal cartilage. The groove width of the cutting portion 32 is greater than the thickness of the cutting portion 32 by 0.5 mm to 2 mm, 0.5 mm to 1 mm, 1 mm to 1.5 mm, or 1.5 mm to 2 mm.

[0052] In the rib cartilage cutting and crushing device provided in the present application, Figure 1 As shown, the elastic member 8 includes a plurality of springs. The spring may be, for example, a pressure spring. The springs are evenly distributed on the wall of the pressing cavity 11. Normally, the outer diameter of the rotating pressing portion 7 matches the inner diameter of the pressing cavity 11, that is, the outer diameter of the rotating pressing portion 7 is slightly smaller than or equal to the inner diameter of the pressing cavity 11, so that the rotating pressing portion 7 can move relative to the pressing cavity 11 along the height direction of the pressing cavity 11 or rotate along the axial direction of the pressing cavity 11. In this way, after a spring is provided on the wall of the pressing cavity 11, the pressing pressure can be used to move downward, and when the movement is completed, the hand is released, the spring rebounds, and the rotating pressing portion 7 is reset.

[0053] In the rib cartilage cutting and crushing device provided in the present application, Figure 1 As shown, at least part of the rotating pressing portion 7 is provided with anti-skid threads. The anti-skid threads are convenient for users to prevent slipping during operation.

[0055] In the rib cartilage cutting and crushing device provided in the present application, in some embodiments, the volume of the cleaning part 4 can be 600cm 3 ~2090cm 3 、600cm 3 ~1000cm3 , 1000cm 3 ~1500cm 3 , or 1500cm 3 ~2090cm 3 Specifically, the diameter of the cleaning part 4 is 7.5cm-11cm, 7.5cm-8.5cm, 8.5cm-9.5cm, 9.5cm-10.5cm, or 10.5cm-11cm, etc., and the height of the cleaning part 4 can be 3.4cm-5.5cm, 3.4cm-4.5cm, or 4.5cm-5.5cm, etc.

[0056] In the rib cartilage cutting and crushing device provided in the present application, in some embodiments, the volume of the cartilage placement part 2 is 461cm 3 ~1900cm 3 、461cm 3 ~1000cm 3 , 1000cm 3 ~1500cm 3 , or 1500cm 3 ~1900cm 3 The diameter of the cartilage placement part 2 is 7cm-11cm, 7cm-8cm, 8cm-9cm, 9cm-10cm, or 10cm-11cm, etc. The height of the cartilage placement part 2 can be 3cm-5cm, 3cm-4cm, or 4cm-5cm, etc.

[0057] In the rib cartilage cutting and crushing device provided in the present application, Figure 1 As shown, the rotary pressing part 7 includes a pressing part and a cutting connection part, and the cutting connection part is used to connect the cutting assembly 3. The diameter of the pressing part is 5cm to 8cm, 5cm to 6cm, 6cm to 7cm, or 7cm to 8cm. The height of the pressing part is 3.5cm to 5.5cm, 3.5cm to 4.5cm, or 4.5cm to 5.5cm. The diameter of the cutting connection part can be 7cm to 11cm, 7cm to 8cm, 8cm to 9cm, 9cm to 10cm, or 10cm to 11cm. The height of the cutting connection part can be 3cm to 5cm, 3cm to 4cm, or 4cm to 5cm.

[0058] Working process of this application:

[0059] In the initial state, if Figure 1As shown, the shell 1 and the cartilage placement part 2 are detachably connected. The cartilage placement part 2 is removed from the device, and after the required rib cartilage to be cut is placed in it, the cartilage placement part 2 and the shell 1 are installed again (for example, it can be screwed in through the thread on the shell 1), and the rotating pressing part 7 is pressed. The rotating pressing part 7 and the cutting component 3 are integrated. The rotating pressing part 7 drives the cutting component 3 to move downward during the spring advancement process. The cutting part 32 passes through the cutting part of the cleaning part 4 through the groove 6, and moves to the cartilage placement part 2 through the transition cavity 13, and cuts the rib cartilage of the cartilage placement part 2. During the cutting process, the rotating pressing part 7 can be rotated to drive the cutting part 32 to rotate, so that the cutting is more complete. After the cutting is completed, the pressing part 7 and the cutting assembly 3 are rotated and rebounded together after releasing the hand. The rib cartilage contains tissue mucus, which will stick to the cutting part 32. During the resetting process of the cutting part 32, the cleaning part 4 pushes the rib cartilage stuck to the cutting part 32 down and returns it to the cartilage placement part 2. Then, the above process is repeated for the next cutting. After repeating this process several times, the rib cartilage can be crushed in the form of cutting force. Finally, the surgical shaping standard is achieved.

[0060] In summary, the costal cartilage cutting and crushing device of the present application can effectively and quickly crush the costal cartilage through the cutting force of the cutting component 3, and further clean the tissue adhered to the cutting part 32 during the cutting process to the cartilage placement part 2 through the cleaning part. The device of the present application can effectively reduce the operation time of the physician during the operation, reduce the fatigue caused by repeated operation process, and can greatly reduce the labor cost, and has a good industrialization prospect.

[0061] In summary, the present application effectively overcomes various shortcomings in the prior art and has high industrial utilization value.

[0062] The above embodiments are merely illustrative of the principles and effects of the present application and are not intended to limit the present application. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present application. Therefore, all equivalent modifications or changes made by a person of ordinary skill in the art without departing from the spirit and technical ideas disclosed in the present application shall still be covered by the claims of the present application.
