Description

Technical Field

[0001] This utility model belongs to the field of testing technology, and in particular relates to an adjustable bone plate clamping device. Background Technology

[0002] With the development of ultrasound technology and its integration with modern medicine, medical ultrasonic scalpels are gradually being applied in surgical procedures. For example, medical ultrasonic scalpels can be used to cut, drill, or grind bone tissue to achieve the purpose of processing bone tissue.

[0003] When testing the efficiency and lifespan of an ultrasonic scalpel using a machine, the scalpel needs to cut the bone plate along a pre-defined path. Different ultrasonic scalpels require different test durations and bone plate sizes. To prevent the bone plate from shifting during testing, it is typically fixed to a mounting plate with bolts. Different sized mounting plates are needed for different bone plate sizes, resulting in a large number of mounting plates or the use of a single large mounting plate with multiple locking holes. This method of fixing and replacing the plate is cumbersome. Furthermore, with the bone plate positioned above the mounting plate, if the ultrasonic scalpel descends a greater distance, it may come into contact with the mounting plate, leading to inaccurate test data. Additionally, cooling media needs to be sprayed during bone plate cutting, and the mounting plate being below the bone plate hinders drainage. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide an adjustable bone plate clamping device and testing device to solve the problem that different fixation plates need to be replaced for bone plates of different sizes, resulting in waste of fixation plates.

[0005] To achieve the above and other related objectives, this utility model provides an adjustable bone plate clamping device, including a frame, a pair of first fixing beams fixed above the frame and arranged parallel to the longitudinal direction of the frame, and a pair of second fixing beams arranged parallel to the transverse direction of the frame. The two ends of the first fixing beams intersect and are fixed to the second fixing beams, and at least one of the first fixing beams can move laterally along the second fixing beams. Each of the first fixing beams is provided with a first fixing member for clamping the bone plate. The first fixing member can move in the width direction of the first fixing beam to adjust the clamping width of the bone plate, and the clamping length of the bone plate is adjusted by the movement of the first fixing beam along the second fixing beam.

[0006] Furthermore, the end faces of each of the first fixed beams are respectively connected to the inner sidewalls of each of the second fixed beams.

[0007] Furthermore, each of the first fixed beams is provided with two first fixing members.

[0008] Furthermore, a first groove is provided on the top of the first fixed beam, and a fourth groove is provided on the side wall of the first fixed beam. The first groove and the fourth groove extend longitudinally along the first fixed beam, and the first fastener is fixed to the first groove by bolts.

[0009] Furthermore, the second fixed beam is connected to the first fixed beam via a first connector.

[0010] Furthermore, the first connector is L-shaped, with one arm of the first connector connected to the second fixed beam and the other arm of the first connector connected to the first fixed beam.

[0011] Furthermore, the side wall of the second fixed beam is provided with a second sliding groove, which extends along the extension direction of the second fixed beam, and the first connecting member is connected to the second sliding groove by bolts.

[0012] Furthermore, the frame is a polygonal structure, and one of the second fixed beams is one of the edges of the frame.

[0013] Furthermore, the bone plate clamping device also includes a pair of third fixing beams arranged longitudinally, with the end faces of each of the second fixing beams connected to the inner sidewalls of the third fixing beams respectively.

[0014] Furthermore, the inner wall of the third fixed beam is provided with a third sliding groove, which extends along the extension direction of the third fixed beam, and the second fixed beam and the third fixed beam are connected by a second connector.

[0015] As described above, this utility model has the following beneficial effects: By setting a first fixing beam and a second fixing beam, the position between the two first fixing beams is adjustable, and the position of the first fixing member on the first fixing beam is adjustable, thereby allowing for the fixing of bone plates of different sizes. After the bone plate is installed on the first fixing beam, there are no other parts at the bottom of the bone plate. When cutting the bone plate, even if the ultrasonic scalpel descends too far, it will not cause errors in the ultrasonic scalpel data; and the bottom of the bone plate in the cutting part is hollow, which facilitates the flow away of the cooling medium sprayed during cutting, preventing it from accumulating on the bone plate and affecting the test.

[0022] In order to describe the present invention in detail, the adjustable bone plate clamping device provided by the present invention will be described in detail below.

[0023] like Figure 1 and Figure 2 As shown, this utility model provides an adjustable bone plate clamping device, including a frame and a pair of first fixing beams 1 and a pair of second fixing beams 2 arranged above the frame. The pair of first fixing beams 1 are arranged parallel to each other along the longitudinal direction of the frame, and the pair of second fixing beams 2 are arranged parallel to each other along the transverse direction of the frame.

[0024] The two ends of the first fixing beam 1 are fixed to the intersection of the first fixing beam 2 and the second fixing beam 2, and at least one of the first fixing beams 1 can move laterally along the second fixing beam 2, thus adapting to bone plates of different widths. The first fixing beam 1 is mounted on the second fixing beam 2, and the first fixing beam 1 can move relative to the second fixing beam 2, thereby changing the distance between the two first fixing beams 1. The two first fixing beams 1 are spaced apart to form a hollow area, and the bone plate is fixed on the first fixing beam 1. The bone plate located in the hollow area is the part that can be cut during testing.

[0025] In some embodiments, both first fixed beams 1 can move relative to the second fixed beam 2, thereby increasing the adjustable range of the spacing between the two first fixed beams 1 and changing the fixed position of the bone plate.

[0026] In some embodiments, to improve the stability of the first fixing beam 1, two second fixing beams 2 are provided, i.e., both ends of the first fixing beam 1 are connected to the second fixing beams 2 respectively. To reduce the volume of the bone plate clamping device, the end faces on both sides of the first fixing beam 1 are connected to the inner walls of the second fixing beams 2, so that when the first fixing beam 1 and the second fixing beam 2 are connected, the top surface of the first fixing beam 1 will not be higher than the top surface of the second fixing beam 2.

[0027] Bone plates of different lengths can be fixed by adjusting the distance between the two first fixing beams 1. A first fixing member 4 for clamping the bone plate is provided at the top of each first fixing beam 1, and the bone plate is fixed to the first fixing beam 1 by the first fixing member 4. The first fixing member 4 can move in the width direction of the first fixing beam 1 to adjust the clamping width of the bone plate, and the clamping length of the bone plate is adjusted by moving the first fixing beam 1 along the second fixing beam 2.

[0028] In some embodiments, two first fixing members 4 are provided on the top of each first fixing beam 1 for clamping and fixing the two ends in the width direction of the bone plate, and the spacing between the two first fixing members 4 is adjusted to accommodate bone plates of different widths.

[0029] To better adjust the spacing between the two first fixing members 4 on the same first fixed beam 1, a first sliding groove 5 is provided at the top of the first fixed beam 1. The first sliding groove 5 extends longitudinally along the first fixed beam 1, that is, it extends along the length direction of the first fixed beam 1. A bolt passes through the first fixing member 4, and the bottom of the bolt abuts against the bottom of the first sliding groove 5, thereby locking the first fixing member 4. The cross-sectional shape of the first sliding groove 5 is rectangular or T-shaped, which increases the contact area between the end face of the bolt and the first sliding groove 5, effectively fixing the first fixing member 4. Alternatively, a slider with a threaded hole can be installed in the first sliding groove 5. Before locking, the bolt and the slider are initially fixed, and the slider can slide relative to the first sliding groove 5. When locking is required, the bolt is tightened, and the slider contacts the bottom of the first fixing member. After locking, the slider cannot slide, that is, the first fixing member 4 cannot slide.

[0030] A fourth sliding groove 12 is provided on the side wall of the first fixed beam 1, extending along the length of the first fixed beam 1. A second sliding groove 6 is provided on the inner side of the second fixed beam 2, extending along the length of the second fixed beam 2. The first fixed beam 1 and the second fixed beam 2 are connected by a first connecting member 8, which is L-shaped. One arm of the first connecting member 8 is connected to the second fixed beam 2, and the other arm is connected to the first fixed beam 1. Both sides of the first connecting member 8 are connected to the fourth sliding groove 12 and the second sliding groove 6 on the side of the first fixed beam 1 by bolts.

[0031] In some embodiments, the adjustable bone plate clamping device further includes a third fixing beam 3, wherein the third fixing beam 3 is a pair and arranged along the longitudinal direction of the frame, and the two end faces of each second fixing beam 2 are respectively connected to the inner sidewall of each third fixing beam 3. The inner sidewall of the third fixing beam 3 is provided with a third sliding groove 7 along its length direction, and the second fixing beam 2 and the third fixing beam 3 are connected by a second connector 9.

[0032] In some embodiments, the frame 10 has a polygonal structure, and one of the second fixing beams 2 is one side of the frame 10. The third fixing beams 3 are the two side edges of the frame 10. One of the second fixing beams 2 is installed between the third fixing beams 3 and can slide relative to the third fixing beam 3. After the second fixing beam 2 is adjusted to the correct position, bolts lock the second connecting member 9 in place. The other second fixing beam 2 is fixed in position relative to the third fixing beam 3 and is part of the frame.

[0033] In some embodiments, the length of the first fixing beam 1 is fixed. If the width of the bone plate is large, a longer first fixing beam 1 can be used. Alternatively, the first fixing beam 1 can be made telescopic, allowing its length to be adjusted as needed. The first fixing beam 1 can also be positioned on top of the second fixing beam 2, with one end of the first connector connected to the side wall of the first fixing beam 1 and the other end connected to the top of the second fixing beam 2. This allows the distance between the two second fixing beams 2 to be constant, requiring only adjustment of the spacing between the first fixing members 4 at the top of the first fixing beam 1. For example, one end of the first fixing beam 1 can be connected to the front end of the frame 10, and the other end can extend to the rear end of the frame 10, requiring only adjustment of the spacing between the two first fixing beams 1.

[0034] A moving mechanism and a clamping mechanism are also installed on the frame 10. The moving mechanism is mounted on the frame 10, and the clamping mechanism is mounted on the moving mechanism. The moving mechanism drives the clamping mechanism to move. The clamping mechanism is used to fix the surgical cutting instrument. The surgical cutting instrument can be an ultrasonic bone scalpel or various surgical blades. The moving mechanism drives the surgical cutting instrument to move, cut, drill, or grind bone plates, thereby testing the efficiency and lifespan of the surgical cutting instrument. The moving mechanism is used to move the surgical cutting instrument relative to the frame 10.

[0035] The third fixed beam 3 is the frame 10, and one of the second fixed beams 2 can also be part of the frame 10. The two second fixed beams 2 are arranged in parallel, and the two first fixed beams 1 are also arranged in parallel.

[0036] The temperature is relatively high during the cutting and drilling of the bone plate, so the cooling medium, usually cooling water, is sprayed. To prevent the cooling water from splashing, a water tank 11 is installed at the bottom of the bone plate clamping device. The cooling water cools the bone plate and then flows into the water tank 11.

[0037] The testing device provided by this utility model allows for the fixing of bone plates of different sizes because the spacing between the two first fixing beams 1 is adjustable, and the position of the first fixing member 4 on the first fixing beam 1 is also adjustable. A hollow area is formed between the two first fixing beams 1, and the bone plate is installed between them. When cutting the bone plate, even if the ultrasonic scalpel descends too far, it will not cause errors in the ultrasonic scalpel data. Furthermore, the bottom of the bone plate in the cutting section is hollow, allowing the cooling medium sprayed during cutting to flow away easily and not accumulate on the bone plate, thus preventing it from affecting the test.

[0038] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
