Description

Technical Field

[0001] The utility model relates to the technical field of testers, in particular to a dynamic torsion tester for orthopedic materials. Background Technique

[0002] Orthopedic (implant) materials are functional materials designed to repair or replace bone functions, and need to meet requirements such as biocompatibility, mechanical strength, and long-term stability. Therefore, after the production and processing of orthopedic (implant) materials, it is necessary to test the torsion and other capabilities of orthopedic (implant) materials.

[0003] The existing Chinese utility model patent with the authorization announcement number of CN219757970U discloses a dynamic torsion tester for orthopedic materials, including a base. A protection component is arranged on the top of the base. A first connecting plate located inside the protection component is arranged on the top of the base. An adjusting component with one end extending into the protection component is arranged inside the base. A driving motor is arranged outside the adjusting component. Fixing components are arranged on the right side wall of the first connecting plate and the output shaft of the driving motor. In this utility model, by setting a servo motor, starting the servo motor drives a gear to rotate through the output shaft. Through the cooperation of the gear and the rack plate, the second connecting plate drives the fixing component on the right to move right or left, thereby adjusting the distance between the two fixing components on the left and right, and further achieving the purpose of being able to adapt to orthopedic materials of different lengths, with high applicability and being convenient for users to use.

[0004] Currently, the traditional torsion tester has the following problems:

[0005] When the existing torsion tester tests the torsion ability of orthopedic materials implanted in the human body, generally, it drives the orthopedic material to rotate continuously in the horizontal direction by means of fixture fixation and motor drive to detect the torsion ability of the orthopedic material. However, when the orthopedic material is actually implanted in the patient's body, since each joint of the human body needs to go through multiple-angle stretching, rotation, lifting and other actions in daily life and work, not limited to horizontal or vertical activities, the result of testing the torsion ability of the orthopedic material by the traditional torsion tester is not accurate enough. At the same time, when using the fixture fixation method to clamp and fix the orthopedic material, the acting force when driving the orthopedic material to rotate will generate a feedback force to the outside, resulting in large wear between the orthopedic material and the fixture, and instead, it is easy to cause damage to the orthopedic material.

[0046] In order to enable those skilled in the art of this technology to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0047] Please refer to Figures 1-6, An orthopedic material dynamic torsion tester includes a test base 10, a central control console 20, a display console 30, and a torsion test mechanism 40. On one side of the top of the test base 10, a central control console 20 is installed. On the side of the central control console 20, a display console 30 is installed on the top of the test base 10 by screws. On the side of the display console 30, a torsion test mechanism 40 is installed on the top of the test base 10 by screws. The torsion test mechanism 40 performs dynamic torsion tests on the orthopedic materials inside. Among them, the torsion test mechanism 40 includes a test base 50, which is installed on the top of the test base 10 by screws. On one side of the top of the test base 50, a universal support component 60 is installed. On one side of the top of the test base 50, a dynamic torsion test component 70 is installed. The dynamic torsion test component 70 is arranged on the side of the universal support component 60. An orthopedic material is clamped and positioned between the dynamic torsion test component 70 and the universal support component 60. Among them, the dynamic torsion test component 70 is electrically connected to the central control console 20, and the display console 30 is electrically connected to the central control console 20.

[0048] In the present utility model, two infrared detection modules 201 are installed on both sides of the bottom of the central control console 20. Between the two infrared detection modules 201, a camera detection module 202 installed at the center of the bottom of the central control console 20 is provided. Among them, both the camera detection module 202 and the infrared detection module 201 are arranged above the test base 50. The camera detection module 202 and the infrared detection module 201 are electrically connected to the central control console 20 through wires.

[0049] When the above solution is actually used, the orthopedic (implant) material to be detected is placed between the dynamic torsion test component 70 and the universal support component 60, and the dynamic torsion test component 70 is started through the central control console 20 to operate, so as to squeeze and fix the orthopedic (implant) material to be detected, ensuring that the orthopedic (implant) material to be detected will not fall off or have other problems during the subsequent rotational torsion ability test. When testing the orthopedic (implant) material to be detected, the orthopedic (implant) material can rotate at multiple tilt angles according to the magnitude of the rotational force, real-time simulating different situations of the orthopedic material during implantation in the human body and performing different movements, improving the accuracy when testing the orthopedic (implant) material.

[0050] In the present utility model, the infrared detection module 201 can detect the angle and position of the orthopedic (implant) material, and determine the stability of the extrusion positioning of the orthopedic (implant) material after adjustment. The camera detection module 202 uses a high-definition camera mode to optically detect the orthopedic (implant) material in the operating state, and transmits the camera results to the inside of the central control console 20 in a light-electric-light manner for data analysis and transmits them to the display console 30 for optical display.

[0051] Specific reference Figure 3 andFigure 5 The test base 50 includes a lower base 501. The lower base 501 is installed on the top of the test base 10 by screws. A convex platform 502 is installed on one side of the top of the lower base 501. A universal support assembly 60 is movably connected to the side of the convex platform 502. A horizontal guide rod 503 is installed on the other side of the top of the lower base 501. A horizontal sliding seat 504 is slidably connected to the outside of the horizontal guide rod 503. The horizontal sliding seat 504 is installed and fixed on the top of the lower base 501 by screws. Among them, a dynamic torsion test assembly 70 is installed on the top of the horizontal sliding seat 504 by screws.

[0052] For the orthopedic material dynamic torsion tester of the present utility model, when testing orthopedic (implant) materials that are too long or too short, the distance between the initial positions of the dynamic torsion test assembly 70 and the universal support assembly 60 can be adjusted by sliding the horizontal sliding seat 504 on the outside of the horizontal guide rod 503, so as to meet the requirements for testing different orthopedic (implant) materials.

[0053] Specifically refer to Figure 6 The universal support assembly 60 includes a lower rotating part 601. The lower rotating part 601 is rotatably connected to the side of the convex platform 502. A universal joint 602 is movably connected inside the lower rotating part 601. The outside of the universal joint 602 is movably connected to an intermediate rotating part 603 arranged on the side of the lower rotating part 601. Among them, the intermediate rotating part 603 is composed of two rotatably connected intermediate rotating parts 6031. Universal joints 602 are movably connected inside both of the two intermediate rotating parts 6031. An upper rotating part 604 is movably connected to one of the intermediate rotating parts 6031 through the universal joint 602 arranged inside. A memory foam positioning block 605 is installed on the side of the upper rotating part 604. An orthopedic material abuts against the inside of the memory foam positioning block 605.

[0054] The orthopedic material dynamic torsion tester of the present utility model has the upper rotating member 604 movably connected to an intermediate rotating member 6031 through a universal joint 602, two intermediate rotating members 6031 movably connected to each other, and the intermediate rotating member 6031 movably connected to the lower rotating member 601 through a universal joint 602, which can ensure that the orthopedic (implant) material extruded by the side of the memory cotton positioning block 605 can be at different angles due to the centrifugal force generated by rotation, realizing the operation of testing the orthopedic (implant) material under different actions. At the same time, the contact part between the memory cotton positioning block 605 and the orthopedic (implant) material uses an elastic memory cotton material. On the one hand, it can reduce the degree of damage when testing the orthopedic (implant) material. On the other hand, it can remember the port positions of the orthopedic (implant) materials tested at different angles. When the orthopedic (implant) material is damaged due to too fast rotation speed, the internal sensing unit of the memory cotton positioning block 605 detects and remembers the port angle of the orthopedic (implant) material in the damaged state, which is convenient for recording.

[0055] Specifically refer to Figure 3 、 Figure 4 and Figure 5 As shown in and

[0056] , the dynamic torsion test assembly 70 includes two side baffles 701. Both side baffles 701 are installed on the top of the horizontal slide 504 by screws. There is a gap between the two horizontal slides 504. A servo cylinder 702 is installed on the side of one side baffle 701; a movable disk 703 is movably arranged between the two side baffles 701. The movable disk 703 is connected to the output end of the servo cylinder 702. A horizontal connecting arm 704 is rotatably connected inside the movable disk 703. The horizontal connecting arm 704 passes through the other side baffle 701; a test disk 705 is installed at the bottom of the horizontal connecting arm 704. The test disk 705 is arranged on the side of the side baffle 701. A plurality of memory cotton positioning blocks 605 are installed at the center and the eccentric position on the side of the test disk 705.

[0056] In this embodiment, a plurality of horizontal grooves 7041 are formed on the outer surface of the horizontal connecting arm 704. The horizontal connecting arm 704 is movably connected to an intermediate gear 7042 through the horizontal grooves 7041. The intermediate gear 7042 is rotatably connected to the side of one side baffle 701; a lower gear 7043 is meshed and connected to the bottom of the intermediate gear 7042. The lower gear 7043 is rotatably connected to the side of one side baffle 701. The lower gear 7043 is connected to the output end of a servo motor 7044. The servo motor 7044 is installed on the side of one side baffle 701.

[0057] In the above embodiments, when driving the orthopedic (implant) material to rotate, the servo motor 7044 is started to operate, driving the lower gear 7043 connected to the output end of the servo motor 7044 to rotate, and causing the intermediate gear 7042 meshed with the top of the lower gear 7043 to rotate. When the intermediate gear 7042 rotates, the horizontal connecting arm 704 connected to its inner side through the horizontal groove 7041 will rotate, driving the orthopedic (implant) material positioned by squeezing the memory cotton positioning block 605 on the side of the horizontal connecting arm 704 to rotate. When the horizontal connecting arm 704 rotates, it operates on the side of the movable disk 703 and does not conflict with the operation of the servo electric cylinder 702.

[0058] For the dynamic torsion tester for orthopedic materials of the present utility model, when squeezing and fixing the orthopedic (implant) material, the servo electric cylinder 702 is started to operate, driving the movable disk 703 connected to the output end of the servo electric cylinder 702 to move horizontally. When the movable disk 703 moves horizontally, it will drive the horizontally connected arm 704 rotatably connected to its inner side to move horizontally inside the intermediate gear 7042, adjusting the horizontal positions of the multiple memory cotton positioning blocks 605 on the side of the horizontal connecting arm 704.

[0059] It should be noted that in the present utility model, the connections, control methods, circuits, systems, etc. between the central control console 20, the infrared detection module 201, the camera detection module 202, the display console 30, the servo motor 7044, and the servo electric cylinder 702 are all prior arts.

[0060] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent replacements or changes, and should be covered by the protection scope of the present utility model.
