Description

Technical Field

[0001] This utility model relates to a plasma spraying device for a surrounding, traveling medical implant. Background Technology

[0002] Medical implants are devices used for medical purposes, typically placed inside or on the body through surgical or non-surgical methods to replace, support, or enhance biological structures, restore function, or improve aesthetics. Materials used in medical implants generally include metals, ceramics, polymers, and biomaterials. To increase the biocompatibility between these materials and bone tissue, ensuring their safety and effectiveness in the human body, the implant surface is coated with a plasma material before implantation to form a coating that further enhances compatibility with bone tissue.

[0003] When plasma spraying existing medical implants, full-area spraying is achieved by controlling the nozzle to rotate and move relative to the implant. However, when the implant has an irregular or complex shape, the distance between the implant and the nozzle cannot be precise. If the distance is too close, the paint tends to accumulate too thickly on the raised parts, forming orange peel or holes; if the distance is too far, the kinetic energy of the atomized particles is insufficient, making it difficult to cover the recessed areas, resulting in a thin coating or dry spraying, and causing unsatisfactory spraying results. Utility Model Content

[0004] The purpose of this invention is to provide a plasma spraying device for surrounding medical implants to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A plasma spraying device for a surrounding medical implant includes a worktable and a plasma spray pump mounted on the worktable, and a support frame mounted on the worktable, wherein a sleeve with a hollow structure is fixedly connected to the support frame.

[0007] A rotating component is installed inside the sleeve along the axial direction, and the rotation of the rotating component is controlled by a driving component set on the worktable.

[0008] A threaded pusher is installed inside the sleeve and connected to the rotating component;

[0009] An elastic telescopic component is installed at the end of the threaded pusher and is equipped with a nozzle that communicates with the plasma spray pump. When the nozzle rotates within the sleeve along the threaded direction, it maintains a stable spraying distance from the implant.

[0010] The above-described circumferential plasma spraying device for medical implants includes a rotating component comprising a support shaft rotatably mounted on the worktable, one end of which is connected to the drive component, and the other end of which is mounted with a connecting arm perpendicular to the support shaft.

[0011] The surrounding traveling plasma spraying device for medical implants as described above: the driving component includes a drive shaft rotatably mounted on the worktable, the drive shaft being driven to rotate by a motor mounted on the worktable, and the drive shaft being connected to the support shaft via a bevel gear set.

[0012] The above-described circumferential medical implant plasma spraying device includes a threaded pusher comprising a drive shaft rotatably mounted on the connecting arm, a gear fixedly sleeved on the drive shaft, and the gear being capable of meshing with a gear ring mounted on the inner wall of the sleeve.

[0013] It also includes a lead screw, which is mounted on the connecting arm and arranged axially along the drive shaft, and the lead screw is threadedly connected to a threaded sleeve that is slidably connected to the drive shaft.

[0014] The above-described circumferential medical implant plasma spraying device includes an elastic telescopic component comprising a plug sleeve installed at the end of the threaded sleeve rod, an inner groove formed in the plug sleeve, a plug rod slidably disposed in the inner groove, a roller rotatably mounted on the end of the plug rod away from the plug sleeve, and a spray head mounted on the plug rod.

[0015] It also includes a spring, which is disposed in the recessed groove, with one end of the spring abutting against the end of the recessed groove and the other end abutting against the insertion rod.

[0016] As described above, the surrounding traveling plasma spraying device for medical implants: the plasma spray pump is connected to the nozzle through a connecting pipe, the connecting pipe includes a first conduit, a second conduit and a third conduit, one end of the first conduit is connected to the plasma spray pump, and the other end is rotatably connected to the support shaft, passing through the support shaft, one end of the second conduit is connected to the first conduit, and the other end is sealed and slidably connected to the third conduit, and the end of the third conduit away from the second conduit is connected to the nozzle.

[0017] The surrounding mobile plasma spraying device for medical implants described above: a receiving frame is interactively arranged on the worktable, and a suction cup capable of adsorbing the implant is installed on the receiving frame.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] After the implant is fixed and inserted into the sleeve, the drive unit and plasma spray pump are activated simultaneously. The drive unit drives the rotating component to rotate, causing the threaded pusher to revolve within the sleeve while simultaneously pushing the nozzle along the sleeve's axis. The plasma spray pump delivers the coating material to the nozzle. When the nozzle sprays onto the implant surface, its movement trajectory within the sleeve is threaded. During the spraying process, the elastic telescopic component remains in contact with the implant, allowing for precise control of the distance between the nozzle and the implant when spraying implants with irregular structures. This avoids spraying distance deviations caused by structural irregularities. A stable spraying distance helps improve the uniformity and consistency of the coating, thereby enhancing the biocompatibility of the implant with bone tissue. Attached Figure Description

Detailed Implementation

[0027] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0028] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0029] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0030] Please see Figures 1-6 In this embodiment of the utility model, a plasma spraying device for a surrounding traveling medical implant includes a workbench 1 and a plasma spraying pump 2 installed on the workbench 1, and also includes a support frame 3 installed on the workbench 1, with a sleeve 4 having a hollow structure fixedly connected to the support frame 3.

[0031] A rotating component is installed inside the sleeve 4 along the axial direction, and the rotation of the rotating component is controlled by a driving component provided on the worktable 1.

[0032] A threaded pusher is installed inside the sleeve 4 and connected to the rotating component;

[0033] An elastic telescopic component is installed at the end of the threaded pusher and is equipped with a nozzle 18 that communicates with the plasma spray pump 2. When the nozzle 18 rotates along the threaded direction inside the sleeve 4, it always maintains a stable spraying distance with the implant.

[0034] In this embodiment, after the implant is fixed and inserted into the sleeve 4, the drive unit and the plasma spray pump 2 are started to work simultaneously. The drive unit can drive the rotating part to rotate, so that while the threaded pusher revolves in the sleeve 4, it can push the nozzle 18 along the axial direction of the sleeve 4. The plasma spray pump 2 delivers the coating material to the nozzle 18. When the nozzle 18 sprays the surface of the implant, its movement trajectory in the sleeve 4 is a circular motion. During the spraying process, the elastic telescopic part is always in contact with the implant to stabilize the distance between the nozzle 18 and the implant. The stable spraying distance helps to improve the uniformity and consistency of the coating, thereby improving the biocompatibility of the implant with bone tissue.

[0035] For further solutions to this utility model, please refer to [link / reference]. Figure 3 The rotating component includes a support shaft 7 rotatably mounted on the worktable 1. One end of the support shaft 7 is connected to the driving component, and the other end is equipped with a connecting arm 9 perpendicular to the support shaft 7.

[0036] The driving component includes a drive shaft 6 rotatably mounted on the worktable 1. The drive shaft 6 is driven to rotate by a motor 5 mounted on the worktable 1, and the drive shaft 6 is connected to the support shaft 7 through a bevel gear set 8.

[0037] Specifically, during the spraying operation on the implant, motor 5 is started. The output shaft of motor 5 is firmly connected to drive shaft 6, ensuring that the output shaft rotates synchronously with drive shaft 6. Through the transmission action of bevel gear set 8, support shaft 7 rotates accordingly, thereby realizing the corresponding movement of nozzle 18 within sleeve 4. While nozzle 18 rotates relative to sleeve 4, it can move along the axial direction of sleeve 4 under the action of threaded pusher, so that the movement trajectory of nozzle 18 within sleeve 4 is threaded, thereby achieving comprehensive spraying of the implant.

[0038] For further solutions to this utility model, please refer to [link / reference]. Figure 4 and Figure 5 The threaded pusher includes a drive shaft 12 rotatably mounted on the connecting arm 9, and a gear 13 is fixedly sleeved on the drive shaft 12. The gear 13 can mesh with a toothed ring 10 mounted on the inner wall of the sleeve 4.

[0039] It also includes a lead screw 11, which is mounted on the connecting arm 9 and arranged axially along the transmission shaft 12. The lead screw 11 is threadedly connected to a threaded sleeve 14 that is slidably connected to the transmission shaft 12.

[0040] It should be noted that: at least one set of strip blocks are provided on the inner wall of the drive shaft 12, and a strip groove 1401 is formed on the outer wall of the threaded sleeve 14 that is slidably connected to the strip blocks. Under the constraint of the strip blocks and the strip groove 1401, the drive shaft 12 and the threaded sleeve 14 can be slidably connected, and the synchronous rotation of the threaded sleeve 14 when the drive shaft 12 rotates is not affected.

[0041] When the aforementioned support shaft 7 rotates, the connecting arm 9 is driven accordingly, causing the transmission shaft 12 to perform circular motion within the sleeve 4. During this process, the gear 13 on the transmission shaft 12 moves relative to the gear ring 10, thus achieving its own rotation while the transmission shaft 12 revolves. Through the setting of the strip block and the strip groove 1401, the threaded sleeve 14 rotates synchronously with the rotation of the transmission shaft 12. At this time, the threaded sleeve 14 rotates relative to the lead screw 11 and is squeezed by the thread, so that the threaded sleeve 14 rotates itself while moving along the axial direction of the lead screw 11, thereby enabling the nozzle 18 to perform plasma spraying on the implant along the axial direction of the sleeve 4.

[0042] For further solutions to this utility model, please refer to [link / reference]. Figure 6The elastic telescopic component includes a plug sleeve 15 installed at the end of the threaded sleeve 14. An inner groove is formed in the plug sleeve 15. A plug rod 16 is slidably disposed in the inner groove. A roller 17 is rotatably installed in the end of the plug rod 16 away from the plug sleeve 15. The nozzle 18 is installed on the plug rod 16.

[0043] It also includes a spring 20, which is disposed in the recessed groove. One end of the spring 20 abuts against the end of the recessed groove, and the other end abuts against the insertion rod 16.

[0044] In detail, during the spraying process of the nozzle 18 on the implant, considering that the irregular shape or complex structure of the implant may lead to improper spraying distance, resulting in uneven coating or material waste, the spring 20 automatically compresses or stretches when the roller 17 moves on the surface of the implant, generating a reverse force to force the roller 17 to always remain in contact with the surface of the implant. By dynamically adjusting the distance between the nozzle 18 and the implant, it is ensured that it is stable within the optimized range. The distance between the nozzle 18 and the implant can be precisely controlled, thereby avoiding spraying distance deviation caused by irregular structure. This not only improves the coating quality but also reduces production costs.

[0045] For further solutions to this utility model, please refer to [link / reference]. Figure 1 and Figure 4 The plasma spray pump 2 is connected to the nozzle 18 via a connecting pipe 19. The connecting pipe 19 includes a first conduit, a second conduit, and a third conduit. One end of the first conduit is connected to the plasma spray pump 2, and the other end is rotatably connected to the support shaft 7. One end of the second conduit is connected to the first conduit, and the other end is sealed and slidably connected to the third conduit. The end of the third conduit away from the second conduit is connected to the nozzle 18.

[0046] The workbench 1 is interactively provided with a receiving frame 21, and the receiving frame 21 is equipped with a suction cup that can adsorb the implant.

[0047] The workbench 1 is equipped with a negative pressure pump, which is connected to the suction cup via a hose. The specific implant fixation method adopts existing technology, and this utility model will not provide further explanation.
