Description

Technical Field

[0001] The utility model relates to the technical field of artificial joint processing, in particular to an intelligent spraying device for artificial joints which is easy to fix. Background Art

[0002] Artificial joints include: knee, hip, elbow, shoulder, finger, and toe joint prostheses. Artificial joints are an artificial organ designed to save joints that have lost their function. They are one of the most effective artificial organs. Plasma arc spraying of Ti and HA coatings on the surface of artificial joints. Plasma sprayed titanium (Ti) and hydroxyapatite (HA) coatings deposited on Ti or its alloy substrates have been used clinically. The bonding strength of plasma sprayed (VPS) Ti coatings can reach 60MPa, which can meet the crystallinity requirements of clinical implants. This treatment method can greatly promote the bone integration of press-fit prostheses.

[0003] The existing plasma intelligent spraying device can complete the spraying work of artificial joints (hip joints).

[0004] When plasma spraying the outer surface of an existing artificial joint (hip joint), a worker is required to place the hip joint in a specified position and manually limit it so that the plasma sprayer can spray its outer surface. However, manually limiting and fixing multiple hip joints is time-consuming, thereby reducing the overall spraying efficiency. Utility Model Content

[0024] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] like Figure 1-5 As shown, the present invention provides an artificial joint intelligent spraying device that is easy to fix. The artificial joint intelligent spraying device specifically comprises a protective frame 1, a limiting platform 3 and a limiting component 6 for automatically limiting the artificial joint. The limiting platform 3 is installed inside the protective frame 1, and a built-in installation box 2 is provided below the limiting platform 3. The limiting component 6 is arranged inside the limiting platform 3, and a cylinder 7 is provided below the limiting component 6. A plurality of placement slots 5 are opened at equal intervals above the limiting platform 3, and a plasma spraying robot arm 4 is installed on the front side of the protective frame 1. The purpose is that the provided spraying device adopts the limiting component 6 inside the limiting platform 3 to automatically limit and fix the artificial hip joint. After the staff places the hip joint in the middle of the placement slot 5 of the limiting platform 3, the hip joints can be synchronously limited by controlling the cylinder 7, so that the staff does not need to manually limit them one by one, thereby further improving the efficiency of the spraying equipment.

[0026] like Figure 3-5 As shown, the limiting component 6 includes a placement base plate 601, a limiting card plate 602, a slide rail 603 and a sliding block 604. The placement base plate 601 is fixed to the inner wall of the limiting platform 3. A limiting card plate 602 is provided on one side of the placement base plate 601. Sliding blocks 604 are fixed on both the left and right sides of the limiting card plate 602. The sliding block 604 is provided with a slide rail 603 on the outside. A driving wheel 9 is provided below the limiting card plate 602, and the bottom end of the driving wheel 9 is fixed to a connecting frame 8.

[0027] The specific implementation is as follows:

[0028] Then the cylinder 7 is started, and the cylinder 7 can move the upper driving wheel 9 upward through the connecting frame 8. When the driving wheel 9 contacts the limiting card plate 602, the limiting card plate 602 moves along the slide rail 603 to the side of the placement base plate 601 through the sliding block 604, and then the hip joint is limited by the limiting card plate 602 and the limiting card plate 602.

[0029] As an embodiment, a groove body is opened at the corresponding position of the placement substrate 601 and the placement groove 5, and the bottom of the hip joint will contact the groove body of the placement substrate 601.

[0030] As an implementation manner, the slide rails 603 are fixed to the left and right inner walls of the limiting platform 3 , and the slide rails 603 are used to limit the horizontal movement of the sliding block 604 .

[0031] As an embodiment, a return spring 10 is installed inside the slide rail 603 , and one end of the return spring 10 is fixedly connected to the sliding block 604 . The return spring 10 can reset the limiting clamping plate 602 .

[0032] like Figure 1 As shown, a door panel is installed on the rear side of the protective frame 1, and the staff can open the door panel from the rear side to take out the hip joint.

[0033] As an embodiment, the bottom end of the cylinder 7 is fixed to the inside of the built-in installation box 2, and the output end of the cylinder 7 is fixed to the outer wall of the bottom side of the connecting frame 8. The cylinder 7 can move the connecting frame 8 up and down. The cylinder 7 is an SC standard cylinder 7, and its model is preferably SC63 / 80 / 100.

[0034] As an implementation method, the position of the limiting card plate 602 corresponding to the driving wheel 9 is designed as an inclined structure. When the driving wheel 9 moves upward, the limiting card plate 602 can move horizontally using its own tilting mechanism.

[0035] Working principle:

[0036] When using this intelligent spraying device for artificial joints that is easy to fix, the staff first places the hip joint in the middle of the placement slot 5 of the built-in installation box 2, and the bottom of the hip joint will contact the slot body of the placement substrate 601, and then start the cylinder 7. The cylinder 7 can move the upper driving wheel 9 upward through the connecting frame 8. When the driving wheel 9 contacts the limiting card plate 602, the limiting card plate 602 moves along the slide rail 603 to the side of the placement substrate 601 through the sliding block 604, and then the hip joint is limited by the limiting card plate 602 and the limiting card plate 602, and then the plasma spraying robot arm 4 is started to spray the hip joint above the limiting platform 3, and finally the cylinder 7 is reset, and the reset spring 10 can reset the limiting card plate 602.
