Description

Technical Field

[0001] This utility model relates to the field of detection device technology, and in particular to a detection device for orthopedic drills. Background Technology

[0002] As people's demands for quality of life and treatment continue to increase, orthopedic surgery is receiving more and more attention from doctors and patients. The purpose of orthopedic surgery is to maximize the reconstruction and restoration of function, which involves internal fixation of fractures. Commonly used instruments in this type of orthopedic surgery include drilling equipment.

[0003] An existing orthopedic surgical drilling device with a warning structure (publication number: CN221533913U) uses a connecting shaft to rotate the drill bit body for drilling. During drilling, if the pressure sensor fails to detect pressure, the corresponding center or side warning light illuminates, and a buzzer plays a prompt sound to alert the doctor, facilitating the doctor to stop drilling, adjust drilling speed, and adjust drilling direction. However, multiple drill bit models need to be changed during the operation. The drill bit size of the orthopedic drilling device must meet certain standards. Size errors may lead to inaccurate drilling, thus affecting the surgical outcome. Therefore, it is necessary to quickly test the drill bit before installation to determine its suitability. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a detection device for orthopedic drills.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A testing device for orthopedic drills includes a testing box, which is a hollow cylindrical structure. A U-shaped bracket is fixedly installed inside the testing box. An adjusting turntable is rotatably mounted on one side of the testing box. Multiple testing probes are circumferentially and evenly slidably inserted into the surface of the bracket. Each testing probe has a shoulder column structure, and a tension spring is sleeved on the surface of each testing probe. Both ends of each tension spring are fixedly mounted to the shoulder of the testing probe and the surface of the bracket, respectively. A neon bulb is fixedly mounted at one end of the shoulder of each testing probe, and a conductive connector is fixedly mounted at one terminal of each neon bulb. A battery and an adjustable resistor are provided on one side of each testing probe. Multiple batteries and adjustable resistors are fixedly mounted on corresponding surfaces of the bracket. A conductive precision adjustment block is rotatably mounted on the adjustment end of each adjustable resistor.

[0007] As a further embodiment of this utility model, each of the precision adjustment blocks is a columnar structure with oblique cut-off, and the surface of each precision adjustment block is uniformly engraved with scale lines around its circumference. The bottom of each adjustable resistor adjustment terminal is threaded with a second fastening bolt for limiting the precision adjustment block.

[0008] As a further embodiment of this utility model, a connecting rod is fixedly installed on one side of each adjustable resistor adjustment terminal, and multiple guide rods are evenly fixedly installed on the surface of the bracket in a circular pattern. The multiple connecting rods are slidably sleeved on the surface of the multiple guide rods, and a spring is sleeved on the surface of each guide rod. The two ends of each spring are fixedly installed to the connecting rod and the surface of the bracket, respectively.

[0009] As a further embodiment of this utility model, the adjusting turntable has an arc-shaped waist groove on the side near the bracket. There are multiple limiting grooves that are evenly distributed around the circumference. The ends of the multiple connecting rods away from the adjustable resistor are slidably installed in the multiple limiting grooves.

[0010] As a further embodiment of this utility model, a lever is fixedly installed on the edge of the adjusting turntable away from the detection box, and multiple limiting blocks are fixedly installed at equal intervals on the edge of the detection box near the adjusting turntable, with threaded holes opened on the surface of each limiting block.

[0011] As a further embodiment of this utility model, the lever has a hollow internal structure and a first fastening bolt is provided inside the lever. The first fastening bolt has a semi-threaded structure, and one end of the first fastening bolt passes through the lever and the outer surface of the adjusting turntable and is threadedly connected to the corresponding limiting block.

[0012] As a further embodiment of this utility model, the detection box has multiple through holes evenly distributed around its circumference on its arc surface, and a transparent glass block is fixedly embedded in each of the through holes. A drill hole penetrating its outer surface is provided on one side of the detection box.

[0013] As a further embodiment of this utility model, one terminal of the battery is connected to the fixed end of the adjustable resistor via a wire, and the other terminal of the battery is connected to the other terminal of the neon bulb via a wire.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. By setting multiple detection probes evenly distributed in a circle, when the drill bit is inserted into the detection box, the multiple detection probes are all pressed against the surface of the drill bit under the action of the corresponding tension spring. If the diameter of the drill bit meets the requirements, the conductive connector connecting the neon bulb is pressed against the surface of the precision adjustment block, thereby connecting the adjustable resistor to form a closed circuit, and the neon bulb will light up. Otherwise, the drill bit is unqualified. This detection operation is convenient, avoids affecting the surgical effect, and improves the accuracy of the use of orthopedic drilling tools.

[0016] 2. By setting an adjustable turntable and an adjustable resistor, when it is necessary to test drill bits of different diameters, simply rotate the adjustable turntable, and then connect it to the corresponding limit block through the threaded connection of the first fastening bolt. The rotation of the adjustable turntable drives the connecting rod to move up and down, which in turn drives the movable end of the adjustable resistor to move, so that the conductive connector is in a different position when testing drill bits of different diameters. At the same time, different voltages are formed in the closed-loop circuit due to different resistance values, which in turn causes the neon bulb to emit different brightness, thus improving the practicality of the equipment.

[0026] Reference Figures 1-5 A detection device for orthopedic drills includes a detection box 1, which is a hollow cylindrical structure. A U-shaped bracket 8 is fixedly installed inside the detection box 1. An adjusting turntable 2 is rotatably mounted on one side of the detection box 1. Multiple detection probes 12 are evenly slidably inserted into the surface of the bracket 8. Each detection probe 12 has a shoulder column structure, and a tension spring 14 is sleeved on the surface of each detection probe 12. Both ends of each tension spring 14 are fixedly installed to the shoulder of the detection probe 12 and the surface of the bracket 8, respectively. A neon bulb 1 is fixedly installed at one end of the shoulder of each detection probe 12. 1. Each neon bulb 11 has a conductive connector 18 fixedly installed on one end of its electrode. Each detection probe 12 has a battery 9 and an adjustable resistor 10 on one side. Multiple batteries 9 and adjustable resistors 10 are fixedly installed on the corresponding surfaces of the bracket 8. Each adjustable resistor 10 has a conductive precision adjustment block 19 rotatably installed on its adjustment end. Each precision adjustment block 19 has a diagonally cut columnar structure. The surface of each precision adjustment block 19 is uniformly engraved with scale lines around its circumference. The bottom of the adjustment end of each adjustable resistor 10 is threaded with a second fastening bolt 20 for limiting the precision adjustment block 19.

[0027] In use, multiple detection probes 12 are evenly distributed in a circle. When the drill bit is inserted into the detection box 1, the multiple detection probes 12 are pressed against the surface of the drill bit under the tension of the corresponding tension springs 14. If the diameter of the drill bit meets the requirements, the conductive connector 18 connecting the neon bulb 11 is pressed against the surface of the precision adjustment block 19, thereby connecting the adjustable resistor 10 to form a closed circuit, and the neon bulb 11 lights up. Otherwise, the drill bit is unqualified. This detection operation is convenient, avoids affecting the surgical effect, and improves the accuracy of the use of orthopedic drilling tools.

[0028] In this embodiment, a connecting rod 16 is fixedly installed on one side of the adjustment end of each adjustable resistor 10. Multiple guide rods 15 are evenly fixedly installed on the surface of the bracket 8. The multiple connecting rods 16 are slidably sleeved onto the surfaces of the multiple guide rods 15. A spring 17 is sleeved on the surface of each guide rod 15. Both ends of each spring 17 are fixedly installed to the connecting rod 16 and the surface of the bracket 8, respectively. A limiting groove 13 with an arc-shaped waist groove is opened on the side of the adjusting turntable 2 near the bracket 8. Multiple limiting grooves 13 are provided and evenly distributed circumferentially. Multiple connecting rods... One end of the adjustable resistor 10 is slidably installed in multiple limiting slots 13. A lever 4 is fixedly installed on the edge of the adjusting turntable 2 away from the detection box 1. Multiple limiting blocks 3 are fixedly installed at equal intervals on the edge of the detection box 1 near the adjusting turntable 2. Each limiting block 3 has a threaded hole on its surface. The lever 4 has a hollow structure inside. A first fastening bolt 5 is provided inside the lever 4. The first fastening bolt 5 has a semi-threaded structure. One end of the first fastening bolt 5 passes through the lever 4 and the outer surface of the adjusting turntable 2 and is threadedly connected to the corresponding limiting block 3.

[0029] In use, by setting the adjustment turntable 2 and the adjustable resistor 10, when it is necessary to detect drill bits of different diameters, simply rotate the adjustment turntable 2, and then connect the first fastening bolt 5 to the corresponding limit block 3 by thread. The rotation of the adjustment turntable 2 drives the connecting rod 16 to move up and down, which in turn drives the movable end of the adjustable resistor 10 to move, so that the conductive connector 18 is in a different position when detecting drill bits of different diameters. At the same time, different voltages are formed in the closed-loop circuit due to different resistance values, and the neon bulb 11 emits different lights, which improves the practicality of the equipment.

[0030] Regarding detection accuracy, the accuracy adjustment block 19 can be rotated so that its arc contact surfaces of different sizes face the conductive connector 18. Then, the second fastening bolt 20 is used to limit the accuracy adjustment block 19, thereby changing the probability of the conductive connector 18 and the adjustable resistor 10 forming a closed-loop circuit. The smaller the arc surface of the accuracy adjustment block 19 faces the conductive connector 18, the higher the detection accuracy of the device.

[0031] In this embodiment, the arc surface of the detection box 1 is uniformly provided with multiple through holes, and a transparent glass block 6 is fixedly embedded in each through hole. A drill hole 7 is provided on one side of the detection box 1, penetrating its outer surface. One terminal of the battery 9 is connected to the fixed end of the adjustable resistor 10 through a wire, and the other terminal of the battery 9 is connected to the other terminal of the neon bulb 11 through a wire.

[0032] In use, a complete circuit is formed by the battery 9, adjustable resistor 10, precision adjustment block 19, conductive connector 18, and neon bulb 11. The position of the movable end of the adjustable resistor 10 is used as a reference. Then, the detection probe 12 drives the neon bulb 11 and the conductive connector 18. Whether the conductive connector 18 can contact the precision adjustment block 19 to form a closed loop circuit depends on whether the drill bit diameter meets the standard for use. When the neon bulb 11 lights up, it can be detected in time through the transparent glass block 6, which facilitates quick judgment and improves the convenience of the equipment in detecting the drill bit diameter.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
