[0031] Preferably, the annular curette comprises a first annular curette 4 and a second annular curette 5 .

[0032] Preferably, the cartilage defect shape trimmer includes a first cartilage defect shape trimmer 6, a second cartilage defect shape trimmer 7, a third cartilage defect shape trimmer 8, a fourth cartilage defect shape trimmer 9, a fifth cartilage defect shape trimmer 10, a sixth cartilage defect shape trimmer 11 and a seventh cartilage defect shape trimmer 12.

[0033] Preferably, the surgical forceps include a first surgical forceps 13 and a second surgical forceps 14 .

[0034] Preferably, the box body is also fixedly provided with a hammer head fixing part 15, a hammer head handle fixing part 16, a surgical scissors head end fixing part 17, a surgical scissors handle end fixing part 18, a ring-shaped scraper handle end fixing part 19, a cartilage defect shape trimmer head end fixing part 20, a cartilage defect shape trimmer handle end fixing part 21, a surgical forceps tail end fixing part 22 and a surgical forceps head end fixing part 23, the hammer head fixing part 15 is used to clamp and fix the head of the hammer head in the box body; the hammer head handle fixing part 16 is used to clamp and fix the handle of the hammer head in the box body; the surgical scissors head end fixing part 17 is used to clamp and fix the head of the surgical scissors and the head of the ring-shaped scraper in the box body; The surgical scissors handle end fixing portion 18 is used to clamp and fix the handle of the surgical scissors in the box body; the ring-shaped scraper handle end fixing portion 19 is used to clamp and fix the handle of the ring-shaped scraper in the box body; the cartilage defect shape trimmer head end fixing portion 20 is used to clamp and fix the trimming ring of the cartilage defect shape trimmer in the box body; the cartilage defect shape trimmer handle end fixing portion 21 is used to clamp and fix the handle of the cartilage defect shape trimmer in the box body; the surgical forceps tail end fixing portion 22 is used to clamp and fix the tail end of the surgical forceps in the box body; the surgical forceps head end fixing portion 23 is used to clamp and fix the head end of the surgical forceps in the box body.

[0035] Preferably, the specific structure of the cartilage defect shape trimmer includes a trimming ring 61, a connecting portion 62 and a handle 63, and the trimming ring 61 and the handle 63 are connected together through the connecting portion 62; the angle A between the central axis of the trimming ring 61 and the length direction of the handle 63 is greater than 0 degrees and less than 90 degrees; the trimming ring 61 includes a circular first blade portion 611, a circular second blade portion 612 and a connecting wall 613 connected between the first blade portion 611 and the second blade portion 612; the blade tip of the first blade portion 611 and the blade tip of the second blade portion 612 are both inclined toward the direction of the central axis of the trimming ring 61; the connecting wall 613 has an arc-shaped bulge that bulges outward in the direction away from the central axis of the trimming ring 61; the connecting wall 613 and the first blade portion 611 and the second blade portion 612 except for the blade tip are all smooth and blunt structures without sharp edges.

[0036] Since the tip of the first blade 611 and the tip of the second blade 612 are both inclined toward the direction of the central axis of the trimming ring 61, the tip of the blade can be prevented from hurting the patient's body to the greatest extent. In addition, since the connecting wall 613 and the first blade 611 and the second blade 612 are all smooth and blunt structures except the tip of the blade, there is no sharp edge, which can also improve safety and prevent the patient's body from being accidentally injured during the operation. The design of the arc-shaped bulge ensures that the appearance of the entire trimming ring 61 is a smooth structure, which improves safety. On the other hand, it improves the mechanical structure of the entire trimming ring 61, so that the connecting wall 613 has a stronger support effect on the first blade 611 and the second blade 612, and can withstand a greater cutting force (including the force applied by the robot arm to the tip of the first blade 611 and the second blade 612 of the trimming ring 61 through the handle 63 and the connecting part 62 when trimming the shape of the cartilage defect, and the reaction force applied by the cartilage to the tip of the first blade 611 and the second blade 612).

[0037] like Figure 3 As shown, the interior of the structure surrounded by the first blade portion 611, the second blade portion 612 and the connecting wall 613 is hollow.

[0038] Preferably, an outer peripheral wall of one end portion 631 of the handle is provided with an external thread for being threadedly connected to a robotic arm of a mobile surgical vehicle.

[0039] Preferably, one end portion 631 of the handle is connected to the mechanical arm of the mobile surgical vehicle by welding or clamping.

[0040] Preferably, the angle A between the central axis of the trimming ring 61 and the length direction of the handle 63 is greater than 10 degrees and less than 30 degrees.

[0041] Preferably, the trimming ring 61 and the handle 63 are welded to the connecting portion 62 .

[0042] Preferably, the trimming ring 61 and the handle 63 are integrally formed with the connecting portion 62 .

[0043] Preferably, the handle 63 is further provided with a gripping handle 632 extending along the length direction of the handle, and the gripping handle 632 is provided with an anti-slip groove.

[0044] Preferably, the grip handle 632 is made of acrylonitrile butadiene styrene plastic or KRO-3 resin.

[0045] like Figure 4 and Figure 5 As shown, the angle α between the extending direction of the tip of the first blade portion 611 and the direction of the central axis of the dressing ring 61 is greater than 0 degrees and less than 12 degrees.

[0046] Preferably, an angle β between an extending direction of the blade tip of the second blade portion 612 and a direction of a central axis of the dressing ring 61 is greater than 0 degrees and less than 10 degrees.

[0047] Preferably, the angle α between the extending direction of the blade tip of the first blade portion 611 and the direction of the central axis of the trimming ring 61 is the same as the angle β between the extending direction of the blade tip of the second blade portion 612 and the direction of the central axis of the trimming ring 61 .

[0048] Preferably, the angle α between the extending direction of the blade tip of the first blade portion 611 and the direction of the central axis of the trimming ring 61 is different from the angle β between the extending direction of the blade tip of the second blade portion 612 and the direction of the central axis of the trimming ring 61 .

[0049] Preferably, the cartilage defect shape trimmer includes trimming rings of different specifications and shapes. The trimming rings can be set to different shapes such as round, oval, etc. according to the shape of the patient's cartilage defect. The material of the trimming ring is a deformable metal material (similar to the material of a can), and the shape of the trimming ring can be adjusted according to the shape of the patient's cartilage defect.

[0050] Preferably, the trimming rings of the first cartilage defect shape trimmer 6, the second cartilage defect shape trimmer 7, the third cartilage defect shape trimmer 8, the fourth cartilage defect shape trimmer 9 and the fifth cartilage defect shape trimmer 10 are circles with gradually increasing diameters, and the trimming rings of the sixth cartilage defect shape trimmer 11 and the seventh cartilage defect shape trimmer 12 are ovals of different sizes.

[0051] During the research and development process, the applicant found that for the cartilage defect shape trimmer with a circular trimming ring, there is a close correlation between the thickness h of the connecting wall 613, the angle α between the extension direction of the tip of the first blade 611 and the direction of the central axis of the trimming ring 61, the angle β between the extension direction of the tip of the second blade 612 and the direction of the central axis of the trimming ring 61, and the force F applied to the handle 63 by the robot arm of the mobile surgical vehicle. In order to determine the relationship between the above parameters, the applicant conducted a large number of experiments.

[0052] In order to simplify the analysis model, the applicant conducted an experiment using a trimming ring 61 in which the angle α between the extension direction of the tip of the first cutting edge 611 and the direction of the central axis of the trimming ring 61 and the angle β between the extension direction of the tip of the second cutting edge 612 and the direction of the central axis of the trimming ring 61 were the same size.

[0053] Since α and β are of the same size, they are uniformly recorded as the angle θ during the experiment. Under the same θ value, the thickness h of the connecting wall 613 and the force F applied to the handle 63 by the robot arm of the mobile surgical vehicle are changed in the form of an arithmetic progression until the force F can cause the first blade 611 or the second blade 612 to be damaged and cannot be used any more, and a set of corresponding values ​​of θ, h and F are recorded. Then, the value of θ is gradually increased in the form of an arithmetic progression, and the corresponding values ​​of h and F of different groups corresponding to different θ values ​​are recorded according to the same experimental conditions and experimental steps, so as to obtain a data table that can characterize the mathematical relationship between θ, h and F.

[0054] Then, the thickness h at which the maximum force F that can be sustained without damaging the first blade 611 or the second blade 612 is selected from the above data table, and the θ value and thickness h at this time are recorded separately and listed in a rectangular coordinate system, and are fitted by SCILAB software to form Figure 6 The curve shown in Figure 1 shows the function corresponding to the thickness-angle function:

[0055]

[0056] Wherein, h is the thickness of the connecting wall 613, in millimeters;

[0057] θ is the angle α between the extending direction of the blade tip of the first blade portion 611 and the direction of the central axis of the dressing ring 61 or the angle β between the extending direction of the blade tip of the second blade portion 612 and the direction of the central axis of the dressing ring 61, in degrees.

[0058] By establishing the above-mentioned thickness-angle function, on the one hand, the connecting wall 613 has sufficient supporting force for the first blade 611 and the second blade 612, and on the other hand, the connecting wall 613 is too thick, which will not cause waste of raw materials and the overall weight of the cartilage defect shape trimmer to be too large. The lightness of the entire trimmer is improved and the operation is more convenient.

[0059] Further, according to a similar idea, the critical value of the force F that can normally cut the cartilage without damaging the subchondral bone when the trimming ring 61 with the same θ value and the same thickness h is trimmed for the shape of the cartilage defect is recorded (due to the different densities of the cartilage and the subchondral bone, the forces that can be borne are also different). By changing the θ value and the thickness h according to an arithmetic progression, a set of corresponding data of the critical value of the force F, θ and the thickness h can be obtained. These corresponding data are listed in a three-dimensional rectangular coordinate system and fitted by SCILAB software to obtain the extreme value relationship of the force F applied by the robot arm of the mobile surgical vehicle to the handle 63. The extreme value relationship is specifically:

[0060]

[0061] Wherein, F is the force applied to the handle 63 by the robot arm of the mobile surgical vehicle, in Newtons.

[0062] The extreme value relationship between the thickness-angle function and the force F is a fitting curve formula fitted based on a large amount of test data. It should be pointed out that the units (millimeter, Newton) of the physical quantities (the thickness h of the connecting wall 613, the force F applied to the handle 63 by the mechanical arm of the mobile surgical vehicle) in the extreme value relationship between the thickness-angle function and the force F are only used to indicate the magnitude of the numerical value and do not participate in the calculation in the formula. This is because the extreme value relationship between the thickness-angle function and the force F is a fitting function obtained by data fitting, rather than a physical formula or mathematical formula obtained by strict mathematical derivation. For example, assuming that h is 10 mm, if the unit is changed to centimeter, then h becomes 1 centimeter, and the unit "millimeter" is only used to indicate the magnitude of the numerical value "10" and does not participate in the calculation in the function. If the unit "millimeter" is not limited to the formula, it may cause the technicians in this field to use the numerical value "1 centimeter" into the formula calculation, resulting in confusing calculation results. The unit "Newton" is the same and does not participate in the calculation in the formula.

[0063] When the cartilage transplant and repair surgery kit of the present invention is used, the doctor can hold the gripping handle 632 on the handle 63 by hand to manually trim the shape of the cartilage defect, or the cartilage transplant and repair surgery kit can be used in conjunction with a mobile surgical vehicle, so that one end 631 of the handle is connected to the mechanical arm of the mobile surgical vehicle by threaded connection, welding or clamping, and the mechanical arm of the mobile surgical vehicle applies force to the cartilage transplant and repair surgery kit to trim the shape of the cartilage defect. Since the density of cartilage and subchondral bone is different, the forces that can be borne are also different. The mechanical arm can accurately control the force so that the force applied to the handle 63 by the mechanical arm satisfies the extreme value relationship, which can avoid harming the patient's body.

[0064] The cartilage transplantation and repair surgery kit of the present invention can be placed on a mobile operating vehicle, which is portable and convenient.

[0065] The above describes the preferred embodiments of the present invention, but it is not intended to limit the present invention. Those skilled in the art may make improvements and changes to the embodiments disclosed herein without departing from the scope and spirit of the present invention.
