Description

Technical Field

[0001] The present invention relates to the technical field of medical device detection, and in particular to intelligent testing equipment for knee joint prosthesis. Background Art

[0002] With the increasing trend of population aging, knee joint diseases have become an important health problem that affects people's quality of life. Artificial knee replacement surgery has been widely used in clinical practice as an effective treatment method. However, the design and performance evaluation of knee prostheses have always been the focus of medical and engineering circles. Traditional artificial knee joint testing equipment often has problems such as unrealistic simulated motion and inaccurate data acquisition, which directly affects the design optimization of the prosthesis and the rehabilitation effect of the patient.

[0003] At present, most artificial knee joint testing equipment on the market uses mechanical simulation or simple mechanical testing methods. These methods cannot fully simulate the complex mechanical behavior of the knee joint in actual movement. In addition, traditional testing equipment also has limitations in data acquisition and processing and cannot provide accurate and comprehensive test data, such as the lack of truly accurate functional simulation, which limits the accuracy and reliability of prosthesis design and performance evaluation.

[0004] In summary, the development of an intelligent test device for knee prosthesis is of great significance for improving the design level of artificial knee prosthesis, optimizing rehabilitation programs, and improving the quality of life of patients. The present invention aims to provide an intelligent test device that can accurately simulate knee joint motion and obtain accurate test data to meet the urgent needs of the medical and engineering communities for high-performance knee prostheses. Summary of the invention

[0005] The purpose of the present invention is to provide an intelligent testing device for knee joint prosthesis to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a kind of intelligent testing equipment for knee prosthesis, comprising a product warehouse, a first lifting track is installed in the product warehouse, a first sliding support is slidably connected to the first lifting track, a prosthesis fixing assembly is installed on the first sliding support, the prosthesis fixing assembly comprises a metal frame fixedly connected to the first sliding support, a plurality of storage trays are installed in the metal frame from top to bottom, a plurality of spaces for placing prostheses are arranged on the top surface of the storage tray, a limiting groove matching the bottom structure of the prosthesis and a plurality of through holes penetrating the bottom of the space are arranged in each space, a retaining groove is arranged on the outside of the limiting groove, and a through groove is arranged between two adjacent spaces in the same row.

[0007] According to the above technical solution, the apertures of the through holes decrease from top to bottom in the order in which they are installed on the metal frame.

[0008] According to the above technical solution, a first storage bin is arranged outside the product bin, a first conduit is installed on the top of the first storage bin, the first conduit is connected to a square bin arranged above the product bin, and a plurality of injection tubes are arranged at the bottom of the square bin.

[0009] According to the above technical solution, a second storage bin is arranged outside the product bin, and a second conduit is installed on the top of the second storage bin.

[0010] According to the above technical solution, the metal frame is composed of a plurality of metal rods, wherein the plurality of vertically arranged metal rods are telescopic structures, a plurality of slots are arranged on the metal frame, and the storage tray is connected to the slots by snap-fitting.

[0011] According to the above technical solution, an entrance and exit are arranged on the side wall of the product bin.

[0012] According to the above technical solution, a detection frame is arranged on one side of the product warehouse, and a clamping mechanism is arranged on the top of the detection frame, the clamping mechanism includes a clamping frame arranged on the detection frame, a first top track is arranged on the clamping frame, two second sliding supports are slidably connected on the first top track, a first telescopic rod is fixedly installed on each second sliding support, and a second adsorption magnetic block is installed on the side wall of each first telescopic rod.

[0013] According to the above technical solution, part of the top of the detection frame is a hollow structure, and an auxiliary component is arranged at the hollow structure. The auxiliary component includes a support plate installed at the hollow structure, and a roller is fixedly installed on the side wall of the support plate.

[0014] According to the above technical solution, a driving assembly is installed on the top of the detection frame, a second lifting track is installed on the side wall of the driving assembly, a second telescopic rod is slidably connected to the second lifting track, the end of the second telescopic rod is fixedly connected to the detection plate, and a plurality of motors are arranged at the bottom of the detection plate, and the output end of each motor faces downward and a detection ball is fixedly installed.

[0015] According to the above technical solution, a second top rail is installed on the detection frame, and the second top rail is slidably connected to the camera mechanism.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: the present invention, by providing an injection tube, changes the previous side spraying to top spraying for cleaning of the prosthesis, which has the advantage of reducing the use of clean water and ensuring that the prosthesis can be successfully cleaned. At the same time, since the two processes of cleaning and dyeing share the injection tube, compared with the side spraying dyeing, the advantage of the top spraying dyeing is that the use of the dyeing medium is greatly reduced, and the fading process of the prosthesis after dyeing can be better monitored. The side spraying dyeing cannot directly dye the inner side wall of the prosthesis, but more often dyes the outer side wall of the prosthesis. By changing to the top spraying dyeing, the fading process of the liquid medium on the inner and outer walls of the prosthesis can be observed at the same time, and the smoothness of the prosthesis surface can be detected by the fading speed of the liquid medium.

[0017] By providing a detection ball, the detection system drives the clamping frame to descend, driving the storage plate clamped and fixed by the first telescopic rod to descend until the storage plate contacts the roller, and then starts the second round of detection of the prosthesis. The second round of detection is divided into three processes. The first process is that the first telescopic rod still maintains the clamping state, and the detection system drives the second telescopic rod to descend along the second lifting track until the detection plate presses the prosthesis. At this time, each detection ball extends into a prosthesis and contacts the prosthesis. The detection system presets a descent value, and then drives the motor to rotate and rub the inside of the prosthesis. When the friction time preset by the detection system is reached, the detection system drives the detection ball and the detection plate to reset, and drives the camera mechanism to monitor the prosthesis. The detection system obtains information, detects the wear resistance of the surface of the prosthesis after friction with the detection ball, and judges whether the prosthesis is qualified after detection through data imaging technology. The rotation time of the detection ball and the contact friction between the detection ball and the prosthesis are All of them can be adjusted to achieve different levels of detection. The second process is that the first telescopic rod still maintains a clamping state, the detection ball contacts the inside of the prosthesis, the detection system drives the second telescopic rod to reciprocate, and then drives the detection plate to reciprocate, and then drives the detection ball to reciprocate. The detection system presets the reciprocating distance of the second telescopic rod to detect the hardness of the prosthesis. The third process is that the first telescopic rod is in a non-clamping state, the detection ball contacts the inside of the prosthesis, and the detection system drives the second telescopic rod to reciprocate. At this time, the placement plate moves on the roller. In this case, the placement plate and the detection ball are in two operating states, simulating the mechanical behavior of the prosthesis installed on the human body and the knee joint in actual movement, providing real and reliable data support for prosthesis performance testing. Under this detection requirement, its purpose is to detect the actual service life of the prosthesis. The above three detection processes are used to complete the detection of the prosthesis's wear resistance, hardness, and actual service life. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-9The present invention provides a technical solution: a knee joint prosthesis intelligent testing device, comprising a product bin 1 for pre-processing a knee joint prosthesis (hereinafter referred to as a "prosthesis"). Specifically, an opening and closing door 2 is arranged on the front wall surface of the product bin 1, and the opening and closing door 2 is opened or closed to control the prosthesis to enter and exit the product bin 1. A first lifting track 3 is installed on the rear inner wall surface of the product bin 1, and a first sliding support 5 is slidably connected to the first lifting track 3. A prosthesis fixing component 4 is detachably installed on the first sliding support 5. The prosthesis fixing component 4 comprises a metal frame 6 fixedly connected to the first sliding support 5, and a plurality of placement trays 7 are sequentially installed from top to bottom in the metal frame 6. A plurality of spaces 8 for placing the prosthesis are evenly arranged on the top surface of the placement tray 7, and a limiting groove 9 matching the bottom structure of the prosthesis and a plurality of through holes 12 penetrating the bottom of the space 8 are arranged in each space 8, and a retaining groove 10 is arranged on the outer side of the limiting groove 9, and a through groove 11 is arranged between two adjacent spaces 8 in the same row;

[0031] The apertures of the through holes 12 decrease from top to bottom in the order in which they are installed on the metal frame 6, thereby controlling the flow rate of the liquid.

[0032] Among them, the prostheses are manually placed in the blanks 8 one by one, and when placing the prostheses, the bottom of the prostheses need to be embedded in the limiting grooves 9, and then the prostheses are pressed downward so that the prostheses are restricted and fixed by the limiting grooves 9. At the same time, the retaining grooves 10 can also provide support for the prostheses. The limiting grooves 9 and the retaining grooves 10 provide a stable detection environment for later detection;

[0033] The metal frame 6 filled with the prosthesis is pushed into the product bin 1 and connected to the first slide support 5. At this time, the position of the first slide support 5 is the lowest point of movement in the first lifting track 3, which is convenient for manual installation. When disassembling, the position of the first slide support 5 also needs to be adjusted to the lowest point of movement in the first lifting track 3 to ensure the safety of personnel during installation.

[0034] Among them, a first storage bin 13 is arranged outside the product bin 1, and the first storage bin 13 is filled with clean water. A first conduit 15 is installed on the top of the first storage bin 13, and the first conduit 15 is connected to a square bin 16 arranged above the product bin 1. A plurality of injection tubes 17 are arranged at the bottom of the square bin 16, and the injection tubes 17 penetrate the product bin 1 and then align with the prosthesis in the product bin 1. Part of the structure of the first conduit 15 extends into the first storage bin 13 and is connected to the first pump. The first pump is driven to operate through the detection system to pump the clean water in the first storage bin 13 into the first storage bin 13. The clean water is sent into the first conduit 15, and then into the square bin 16 through the first conduit 15. The clean water is stored in the square bin 16. When the square bin 16 is full, the clean water in the square bin 16 is transported to the product bin 1 through the injection tube 17. Several injection tubes 17 simultaneously inject water into all the prostheses below to clean the prostheses. At this time, the prostheses in the uppermost placement tray 7 of the metal frame 6 begin to be cleaned with clean water first, and the clean water is transported downward one by one through the through hole 12 until all the prostheses loaded on the placement tray 7 can be cleaned;

[0035] There are several through holes 12, one of which is aligned with the prosthesis below, and the other is aligned with the outside of the prosthesis. With the through holes 12 whose apertures decrease from top to bottom, it is ensured that the clean water can clean both the prosthesis and the outside of the prosthesis. The prosthesis is cleaned to remove impurities on the surface of the prosthesis, which is convenient for coloring the prosthesis later, and to soak the prosthesis, which can more effectively monitor the fading of the liquid medium and avoid the adhesion of the liquid medium.

[0036] Among them, a second storage bin 14 is arranged outside the product bin 1, and the second storage bin 14 is filled with a dyeing medium. A second conduit 18 is installed on the top of the second storage bin 14, and the second conduit 18 is connected to a square bin 16 arranged above the product bin 1. Part of the structure of the second conduit 18 extends into the second storage bin 14 and is connected to a second pump. The second pump is driven to operate by a detection system to transport the dyeing medium in the second storage bin 14 into the second conduit 18, and then into the square bin 16 through the second conduit 18. Then, the liquid medium in the square bin 16 is transported to the product bin 1 through an injection tube 17. A plurality of injection tubes 17 simultaneously inject the liquid medium into all the prostheses below to dye the prostheses.

[0037] The liquid medium is a mixture of dye medium and clean water. Micro intelligent valves are arranged in the first conduit 15, the injection tube 17 and the second conduit 18. The micro intelligent valves are controlled by the detection system and are opened and closed in time in coordination with the entire detection process.

[0038] For cleaning of the prosthesis, the previous side spray is changed to top spray, which has the advantage of reducing the use of clean water and ensuring that the prosthesis can be successfully cleaned. At the same time, since the two processes of cleaning and dyeing share the injection tube 17, compared with the side spray dyeing, the advantage of top spray dyeing is that the use of dyeing medium is greatly reduced, and the fading process of the prosthesis after dyeing can be better monitored. The side spray dyeing cannot directly dye the inner side wall of the prosthesis, but more often dyes the outer side wall of the prosthesis. By changing to top spray dyeing, the fading process of the liquid medium on the inner and outer walls of the prosthesis can be observed at the same time, and the smoothness of the prosthesis surface can be detected by the fading speed of the liquid medium;

[0039] The process of conveying the dyeing medium into the square bin 16 is divided into the following steps:

[0040] Step 1: After the prosthesis is cleaned, half of the capacity of the square bin 16 is reserved for clean water, and then the other half of the capacity of the dyeing medium is transported into the square bin 16, so that a liquid medium with a ratio of 1:1 is formed. The liquid medium is used as a top spray material to spray the prosthesis. The liquid configured in this ratio is first coated on the surface of the prosthesis to remove the clean water remaining on the surface of the prosthesis;

[0041] Step 2: While delivering the liquid medium proportioned in step 1, gradually deliver the dyeing medium into the square bin 16, so that the liquid medium proportion of the prosthesis is gradually biased towards the dyeing medium. The detection system sets the time for spraying the liquid medium. When the set time for spraying the liquid medium is reached, the liquid medium is stopped from being sprayed, and the first detection process of the prosthesis is started;

[0042] Step 3: After the first fading process of the liquid medium is monitored, the square bin 16 is emptied, and after the square bin 16 is filled with the dyeing medium, the dyeing medium is sprayed on the prosthesis. The detection system sets the time for spraying the dyeing medium. When the set time for spraying the dyeing medium is reached, the dyeing medium spraying is stopped, and the second detection process for the prosthesis is started;

[0043] Camera components are arranged at the four corners of the bottom of the storage tray 7 and the inner top surface of the product bin 1, and the prosthesis is monitored in real time through the camera components. The detection result of the prosthesis is obtained by monitoring the fading speed of the liquid medium and the retention of the prosthesis surface after fading;

[0044] Among them, for the first detection process of the prosthesis, the detection system sets the monitored fading speed of the liquid medium as J1, and sets the rated standard fading speed of the liquid medium as J2. If J1 is greater than or equal to J2, it means that the surface of the prosthesis is smooth and the detection result is qualified. If J1 is less than J2, it means that the smoothness of the surface of the prosthesis is low and the detection result is unqualified. The liquid medium used in the first detection process of the prosthesis contains clean water, and the liquid medium has low viscosity and high diffusivity, which has advantages in detecting the fading of the liquid medium on the surface of the prosthesis, and the detection effect is better;

[0045] Among them, for the second detection process of the prosthesis, if the detection system detects that there is residual chromosome medium on the surface of the prosthesis, it means that the prosthesis is unqualified. The chromosome medium used in this detection process has high viscosity. If the chromosome medium actively fades on the surface of the prosthesis and there is no residue on the surface of the prosthesis, it means that the prosthesis is qualified in the high-standard detection process, thereby improving the reliability of the prosthesis detection. In addition, the chromosome medium is darker in color than the liquid medium, which makes it easier for the camera component to detect the residual situation on the surface of the prosthesis;

[0046] Among them, a lighting structure is set in the product warehouse 1 to cooperate with the camera component.

[0047] The metal frame 6 is an externally connected structure, which can be remotely connected to the detection system after being connected to the first sliding support 5. The metal frame 6 is driven to operate by the detection system. The metal frame 6 is composed of a plurality of metal rods 19, wherein the plurality of vertically arranged metal rods 19 are telescopic structures with telescopic functions. After the detection of the prosthesis in the storage tray 7 is completed, the detection system drives the first sliding support 5 to move up and down along the first lifting track 3 and then cooperates with the lifting and lowering of the metal rods 19, so as to drive the storage tray 7 to move up and down to a certain extent, so that the storage tray 7 moves to a height flush with the entrance and exit 20 arranged on the side wall of the product bin 1;

[0048] The connection between the metal frame 6 and the storage tray 7 is a snap-fit ​​connection, that is, a plurality of slots 21 are provided on the metal frame 6, and the storage tray 7 is snap-fitted into the slots 21 from the side. When the storage tray 7 moves to a height flush with the entrance 20, it is taken out by a clamping mechanism 22 provided on one side of the product bin 1 for the next round of inspection;

[0049] Among them, a first adsorption magnetic block 23 is arranged on the side wall of the storage tray 7, a detection frame 24 is arranged on one side of the product bin 1, a clamping frame 25 is arranged on the top of the detection frame 24, and two supporting columns of the clamping frame 25 have a lifting function, which is controlled by the detection system to cooperate with the detection process of the prosthesis. A first top track 26 is arranged on the clamping frame 25, and two second sliding supports 27 are slidably connected on the first top track 26. A first telescopic rod 28 is fixedly installed on each second sliding support 27, and a second adsorption magnetic block 29 is installed on the side wall of each first telescopic rod 28;

[0050] Among them, after the storage tray 7 moves to the height flush with the entrance and exit 20, the detection system drives the two second sliding supports 27 to move in opposite directions on the first top rail 26 until the distance between the two second sliding supports 27 is maximized, and then drives the first telescopic rod 28 to extend until the first telescopic rod 28 extends into the entrance and exit 20, and then the detection system drives the two second sliding supports 27 to move toward each other, driving the two first telescopic rods 28 to clamp the storage tray 7, and then the first adsorption magnetic block 23 and the second adsorption magnetic block 29 are magnetically adsorbed, and the storage tray 7 is double-clamped by the clamping of the first telescopic rod 28 and the magnetic attraction of the magnetic blocks to ensure the movement stability of the storage tray 7. After the storage tray 7 is clamped and fixed, the first telescopic rod 28 begins to retract and reset, and the storage tray 7 gradually moves out of the metal frame 6. After moving to the preset position on the detection frame 24, the first telescopic rod 28 stops moving and starts the second round of detection;

[0051] Part of the top of the detection frame 24 is a hollow structure, and an auxiliary component 30 is arranged at the hollow structure. The auxiliary component 30 includes a support plate 31 installed at the hollow structure, and a roller 32 is fixedly installed on the side wall of the support plate 31. A driving component 33 is installed on the top of the detection frame 24, and a second lifting track 34 is installed on the side wall of the driving component 33. A second telescopic rod 35 is slidably connected to the second lifting track 34, and the end of the second telescopic rod 35 is fixedly connected to the detection plate 36. A plurality of motors 37 are arranged at the bottom of the detection plate 36, and the output end of each motor 37 is downward and fixedly installed with a detection ball 38, and the position arrangement of the detection ball 38 matches the position arrangement of the prosthesis on the storage tray 7;

[0052] A second top rail 39 is installed on the detection frame 24, and a camera mechanism 40 is slidably connected to the second top rail 39, and the camera mechanism 40 is used to monitor the prosthesis below to obtain prosthesis detection information;

[0053] The detection system drives the clamping frame 25 to descend, driving the storage tray 7 clamped and fixed by the first telescopic rod 28 to descend until the storage tray 7 contacts the roller 32, and then starts the second round of detection of the prosthesis. The second round of detection is divided into three processes. The first process is that the first telescopic rod 28 still maintains the clamping state, and the detection system drives the second telescopic rod 35 to descend along the second lifting track 34 until the detection plate 36 presses the prosthesis. At this time, each detection ball 38 extends into a prosthesis and contacts the prosthesis. The detection system presets a descending value, and then drives the motor 37 to run, driving the detection ball 38 to rotate and rub the inside of the prosthesis. When the friction time preset by the detection system is reached, the detection system drives the detection ball 38 and the detection plate 36 to reset, and drives the camera mechanism 40 to monitor the prosthesis. The detection system obtains information, detects the wear resistance of the surface of the prosthesis after the detection ball 38 rubs, and judges whether the prosthesis is qualified after the detection through data imaging technology. The rotation time of the detection ball 38 and the contact friction between the detection ball 38 and the prosthesis are The force can be adjusted to achieve different levels of detection. The second process is that the first telescopic rod 28 still maintains the clamping state, the detection ball 38 contacts the inside of the prosthesis, and the detection system drives the second telescopic rod 35 to reciprocate, which then drives the detection plate 36 to reciprocate, and then drives the detection ball 38 to reciprocate. The detection system presets the reciprocating distance of the second telescopic rod 35 to detect the hardness of the prosthesis. The third process is that the first telescopic rod 28 is in a non-clamping state, the detection ball 38 contacts the inside of the prosthesis, and the detection system drives the second telescopic rod 35 to reciprocate. At this time, the storage tray 7 moves on the roller 32. In this case, the storage tray 7 and the detection ball 38 are in two operating states, simulating the mechanical behavior of the prosthesis installed on the human body and the knee joint in actual movement, providing real and reliable data support for the prosthesis performance detection. Under this detection requirement, its purpose is to detect the actual service life of the prosthesis. The wear resistance, hardness, and actual service life of the prosthesis are detected through the above three detection processes.

[0054] Conducting internal wear resistance testing of the prosthesis first can prevent the prosthesis from having its surface smoothness destroyed by subsequent testing processes, which can cause inaccurate test results.

[0055] The above tests are all conducted by contacting the test ball 38 with the prosthesis, the purpose of which is to simulate the situation where the joint is stuck in the prosthesis, and to test whether the joint can still maintain normal use after a preset degree of movement inside the prosthesis, so as to ensure the effectiveness of the prosthesis test;

[0056] A data analysis system is set up in the detection system, and the collected data is transmitted to the data analysis system via a wireless network. The data analysis system uses advanced algorithms to process and analyze the data and generate a prosthesis detection data report.
