Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment processing, and in particular to a hip and knee joint processing surface treatment system. Background Art

[0002] Hip and knee replacement surgery is an effective method for treating serious hip and knee diseases. The purpose of the surgery is to relieve pain, restore joint function and improve the patient's quality of life by replacing damaged hip and knee joint components.

[0003] The replacement prosthesis needs to go through a series of processing steps during the production process to ensure that it meets strict quality standards and the individual needs of patients. In order to promote the combination of bone tissue and prosthesis and improve the stability and long-term effect of the prosthesis, a special coating, such as hydroxyapatite or other biocompatible materials, needs to be applied to the surface of the prosthesis. The common coating process is physical vapor deposition, that is, the coating material is deposited on the surface of the prosthesis by evaporation. The prosthesis is placed in a processing chamber, and steam is sprayed above the prosthesis through a nozzle, and the steam is waited for to be deposited on the surface of the prosthesis to complete the coating operation.

[0004] In actual applications, the uniformity of the coating will undoubtedly affect the effect of the coating material in promoting the integration of the patient's bone tissue and the prosthesis. However, when the prosthesis is coated by physical vapor deposition, the flux distribution of the deposited material reaching the prosthesis surface will follow the cosine law, that is, the area on the prosthesis surface perpendicular to the direction of the evaporation source will receive more deposited material, and the area with a larger angle with the vertical direction will receive less deposition. Therefore, when the prosthesis surface is coated, the uniformity of the prosthesis surface coating cannot be guaranteed.

[0005] Therefore, we propose a surface treatment system for hip and knee joint machining. Summary of the invention

[0006] The main purpose of the present invention is to provide a hip and knee joint machining surface treatment system.

[0007] To achieve the above object, the technical solution adopted by the present invention is:

[0008] A hip and knee joint surface treatment system comprises a carrying frame and an evaporation chamber, the top of the carrying frame is slidably connected to an operating chamber, the evaporation chamber is fixedly connected to the top of the operating chamber, a guide pipe is provided on the inner side of the evaporation chamber, the guide pipe runs through the operating chamber, a side exhaust port is installed at the bottom end of the guide pipe, the top of the carrying frame is slidably connected to a supporting platform, the position of the side exhaust port corresponds to the center point of the supporting platform, the top of the supporting platform is slidably connected to a plurality of rotating platforms, and the plurality of rotating platforms are symmetrically distributed with the center point of the supporting platform as the symmetry center, the tops of the plurality of supporting platforms are fixedly connected to two fixed seats, the fixed seat is slidably connected to an extension block, a clamping plate is provided on one side of the extension block, a scale is provided on the top of the rotating platform, and a positioning rod is fixedly connected to one side of the clamping plate.

[0009] A further improvement of the present invention is that a guide seat is fixedly connected to the outer side of the supporting frame, a connecting rod is fixedly connected to the outer side of the working bin, and the connecting rod slides inside the guide seat.

[0010] A further improvement of the present invention is that a support base is fixedly connected to the bottom end of the load-bearing frame, a hydraulic rod is fixedly connected to the top end of the support base, and an output end of the hydraulic rod is connected to the linkage rod.

[0011] A further improvement of the present invention is that a material conveying pipe is fixedly connected to the top of the evaporation bin, an exhaust pipe is fixedly connected to one side of the operation bin, and a conveying pipe is connected between the operation bin and the guide pipe.

[0012] A further improvement of the present invention is that an extension rod is fixedly connected to the bottom end of the rotating platform, a limit block is fixedly connected to the bottom end of the extension rod, a transmission seat is rotatably connected inside the supporting frame, and the limit block slides inside the transmission seat.

[0013] A further improvement of the present invention is that a use process of a hip and knee joint processing surface treatment system comprises the following steps:

[0014] S1. The staff can place several prostheses on the top of several rotating platforms respectively. Then the staff can adjust the position of the clamping plate so that the clamping plate contacts the prosthesis to complete the clamping and limiting operation of the prosthesis. Then the staff can adjust the extension block to a suitable position according to the actual situation. When the extension block moves, it will drive the clamping plate and the prosthesis to move synchronously, so that the prosthesis can be at a suitable height during the coating operation. Then the staff can adjust the position of the clamping plate and the prosthesis according to the scale value corresponding to the position of the positioning rod until the prosthesis is located at the center of the rotating platform and wait for subsequent coating operations.

[0015] S2. After the clamping and fixing operation of the prosthesis is completed by the clamping plate, the working chamber will move vertically downward until the bottom of the working chamber slides into the inside of the load-bearing frame, and then the vacuum pump connected to the exhaust pipe will extract the air inside the working chamber. At this time, the staff can introduce the coating material into the evaporation chamber through the conveying pipe. The evaporation chamber is equipped with an electric heating plate to heat and evaporate the coating material, and the steam will enter the inside of the guide pipe through the conveying pipe, and finally be discharged through the side exhaust port fixed at the bottom of the guide pipe. The discharged steam will be deposited on the surface of the prosthesis, thereby completing the coating operation of the prosthesis;

[0016] S3. When the side exhaust port discharges steam, it will be discharged from the four sides of the side exhaust port and diffuse outward. The position of the side exhaust port corresponds to the center of the supporting platform. Several rotating platforms are symmetrically distributed with the center point of the supporting platform as the symmetry center, so that the diffused steam will be deposited on the surface of the prosthesis at the top of the rotating platform. Since the steam follows the cosine law when depositing, the closer the prosthesis is to the side exhaust port, the greater the amount of deposition received, and the farther the distance is, the less the amount of deposition received. The amount of deposition received at the center of the prosthesis approaches the average amount of deposited material on both sides of the prosthesis. When the rotating platform drives the prosthesis to rotate, the distance between the remaining areas of the prosthesis except the center and the side exhaust port will continue to change, so that the amount of deposition received by the areas on both sides of the prosthesis will approach the deposition amount in the center of the prosthesis, thereby ensuring the uniformity of the coating on the surface of the prosthesis.

[0017] Compared with the existing technology, when coating the surface of the prosthesis, the cooperation of components such as the side exhaust port and the rotating platform can make the amount of deposition received by each area of ​​the prosthesis surface tend to be averaged, avoiding the situation where the amount of deposition received by different positions of the prosthesis varies greatly, thereby ensuring the uniformity of the prosthesis coating process.

[0018] Compared with the prior art, when coating a prosthesis, several prostheses can be coated at the same time, and the coating uniformity between the several prostheses can be ensured, thereby achieving the purpose of improving the working efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In this embodiment, the supporting frame 1 is used to support and connect various components, so as to complete the coating processing operation on the surface of the prosthesis. The operating chamber 2 sliding on the top of the supporting frame 1 is used to protect the prosthesis during the operation, and with the assistance of the vacuum pump, a vacuum environment can be formed inside the operating chamber 2, thereby reducing the interference of impurities in the gas during the coating operation on the prosthesis, so that the deposited material can be more tightly and firmly combined with the prosthesis. An evaporation chamber 21 is fixed on the top of the operating chamber 2. The evaporation chamber 21 is used to heat and evaporate the coating material. A guide tube 22 is provided on the inner side of the evaporation chamber 21. The evaporated steam will enter the interior of the guide tube 22 and pass through the side exhaust port installed at the bottom of the guide tube 22. The steam is discharged from the port 3, and because the exhaust holes of the side exhaust port 3 are located around, the steam will be discharged and diffused around the side exhaust port 3. The supporting platform 4 sliding on the top of the supporting frame 1 is used to carry the rotating platform 41. There are several rotating platforms 41, and the several rotating platforms 41 are symmetrically distributed with the center point of the supporting platform 4 as the symmetry center. The staff can place several rotating platforms 41 on the top of the supporting platform 4 to complete the coating operation of several prostheses at the same time. A fixing seat 42 is fixed on the top of the supporting platform 4, and an extension block 43 is slidable inside the fixing seat 42. The staff can make the extension block 43 drive the clamping plate 4 by vertically sliding the extension block 43. 4 is vertically moved to adjust the height of the clamping plate 44, which is used to clamp the prosthesis. The clamping plate 44 is connected to the extension block 43 through a self-locking telescopic rod, so that the staff can adjust the position of the clamping plate 44 to make the clamping plate 44 contact the prosthesis, thereby completing the clamping operation of the prosthesis.

A scale 45 is provided on the top of the rotating platform 41, and the staff can adjust the position of the two clamping plates 44 according to the value of the scale 45 corresponding to the position of the positioning rod 46, so that the clamping plate 44 can be used to clamp the prosthesis. The center position of the prosthesis corresponds to the center position of the rotating platform 41. Due to the clamping of the clamping plate 44, when the rotating platform 41 rotates, the prosthesis can stably follow the rotating platform 41 for synchronous movement. When the side exhaust port 3 discharges steam, the rotating platform 41 will drive the prosthesis to rotate. Since the center position of the prosthesis corresponds to the center position of the rotating platform 41, the distance between each position of the prosthesis except the center position and the side exhaust port 3 will change periodically, that is, the distance between the area on both sides of the prosthesis and the side exhaust port 3 will maintain an increase and decrease cycle, so that the amount of steam deposited on the surface of the prosthesis will be close to the average, thereby ensuring the uniformity of the prosthesis coating.

[0029] Among them, a guide seat 11 is fixedly connected to the outside of the supporting frame 1, and a connecting rod 23 is fixedly connected to the outside of the working chamber 2, and the connecting rod 23 slides inside the guide seat 11; the guide seat 11 fixed on the outside of the supporting frame 1 is used to extend the supporting frame 1, and a connecting rod 23 is fixed to the outside of the working chamber 2, and the connecting rod 23 slides inside the guide seat 11, so that when the working chamber 2 slides vertically, the vertical movement will be guaranteed through the guiding constraints of the connecting rod 23 and the guide seat 11, so that the bottom of the working chamber 2 can move to the inside of the supporting frame 1, so that the working chamber 2 and the supporting frame 1 maintain close contact, so that the vacuum pump can extract the air inside the working chamber 2, so that the coating operation of the prosthesis can be carried out stably.

[0030] Among them, a support base 12 is fixedly connected to the bottom end of the supporting frame 1, a hydraulic rod 13 is fixedly connected to the top end of the supporting base 12, and the output end of the hydraulic rod 13 is connected to the connecting rod 23; the support base 12 fixed at the bottom end of the supporting frame 1 is used to support the supporting frame 1, so that the supporting frame 1 can complete the supporting operation of other components, and a hydraulic rod 13 is fixed to the top end of the supporting base 12, and the output end of the hydraulic rod 13 is connected to the connecting rod 23, so that the hydraulic rod 13 can drive the connecting rod 23 to move vertically, and then the connecting rod 23 can drive the working bin 2 to move, thereby completing the purpose of moving the working bin 2 to a suitable position.

[0031] Among them, a material delivery pipe 24 is fixedly connected to the top of the evaporation bin 21, an exhaust pipe 25 is fixedly connected to one side of the operation bin 2, and a delivery pipe 26 is connected between the operation bin 2 and the guide pipe 22; the material delivery pipe 24 fixed at the top of the evaporation bin 21 is used to introduce the coating material into the evaporation bin 21, so that the coating material can be heated and evaporated by the electric heating plate installed inside the evaporation bin 21, thereby completing the coating operation of the prosthesis; the exhaust pipe 25 fixed on one side of the operation bin 2 is used to connect the operation bin 2 with a vacuum pump, so that during the coating operation, the air inside the operation bin 2 can be extracted to form a vacuum environment inside the operation bin 2, thereby avoiding the influence of gas on the coating effect during the coating operation; the delivery pipe 26 connected between the operation bin 2 and the guide pipe 22 is used to introduce steam into the guide pipe 22, so that the steam can be transported through the guide pipe 22 to the inside of the side exhaust port 3, and then discharged through the side exhaust port 3, to perform the coating operation on the prosthesis inside the operation bin 2.

[0032] Among them, the bottom end of the rotating platform 41 is fixedly connected with an extension rod 47, and the bottom end of the extension rod 47 is fixedly connected with a limit block 48. The inside of the supporting frame 1 is rotatably connected with a transmission seat 14, and the limit block 48 slides inside the transmission seat 14; the extension rod 47 fixed at the bottom end of the rotating platform 41 is used to extend the rotating platform 41 and position the rotating platform 41. A plurality of holes are opened inside the supporting platform 4. When the staff places a plurality of rotating platforms 41 on the top of the supporting platform 4, it is necessary to insert the extension rod 47 fixed at the bottom end of the rotating platform 41 into the hole, so that the plurality of rotating platforms 41 can be symmetrically distributed with the center point of the supporting platform 4 as the symmetrical center, thereby ensuring that the top of the plurality of rotating platforms 41 The distance between the prosthesis and the center of the supporting platform 4 is the same, so that the deposition amount on the surface of several prostheses tends to be the same during the coating operation. The bottom end of the extension rod 47 is fixed with a limit block 48, and the limit block 48 slides inside the transmission seat 14. The transmission seat 14 is connected to the output end of the driving motor installed inside the supporting frame 1, so that the transmission seat 14 can drive the limit block 48 to rotate through the drive motor, and the limit block 48 can drive the rotating platform 41 to rotate through the extension rod 47, so that the prosthesis on the top of the rotating platform 41 can keep rotating during the coating operation, and the distance between the two side areas of the prosthesis and the side exhaust port 3 will change periodically, so as to achieve the purpose of making the deposition amount at each position on the surface of the prosthesis tend to be the same.
