Description

Technical Field

[0001] The invention relates to the technical field of torque screwdrivers, in particular to a torque screwdriver with a detection function. Background Art

[0002] Screw thread slippage is a very common cause of internal fixation failure in clinical practice. If the torque applied when implanting the screw exceeds the bone's tolerance limit, thread slippage will occur, ultimately reducing the screw's pull-out strength by 80% or even more, causing the original fixation effect to deteriorate or even fail. Currently, the main methods for preventing thread slippage in clinical practice are the use of filling materials, digital torque screwdrivers, and changes in thread design. Some studies have also used new methods such as acoustic emission to detect and prevent thread slippage.

[0003] The existing technical solutions have the following defects: it is not convenient to quickly replace the screwdriver head according to needs, it is not convenient to quickly detect the screw tightening data, and it is not convenient to store the screwdriver for carrying. Therefore, the present invention provides a torque screwdriver with a detection function to solve the above-mentioned problems. Summary of the invention

[0014] 1. A screwdriver body, a first clamping block and a bolt are provided. When the screwdriver body needs to be replaced, the nut at the left end of the bolt is removed, and the bolt is taken out from the inside of the installation slot. Then the screwdriver body is pulled downward to drive the clamping slot to pressurize the first clamping block, so that the first clamping block squeezes the first spring to contract. At this time, the screwdriver body is no longer limited and can be taken out, so that the screwdriver head can be quickly replaced according to needs;

[0015] 2. It is equipped with a sensor, a screwdriver body and a processor. When the screwdriver body is working, the sensor is responsible for measuring and recording the torque value and rotation angle, and transmitting them to the processor. The processor has a pre-programmed setting program to analyze the current rotation angle-torque slope under different bone density categories. According to the bone density input by the interactive module, the current tightening degree is recorded and displayed in real time on the feedback module, which is convenient for rapid detection of screw tightening data;

[0016] 3. A hook block, a second clamp block and a storage slot are provided. In order to facilitate the carrying of the torque screwdriver, after the screwdriver body is disassembled, the second clamp block slides to the left to squeeze the third spring, and the second clamp block no longer engages with the hook block. At this time, the processor is driven to flip through the torsion spring on the right, and the processor drives the hook block to flip and open the upper end of the insulating shell. At this time, the screwdriver body can be placed in the storage slot for storage, which is convenient for storing the screwdriver for carrying. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] 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.

[0023] See also Figure 1-4 The present invention provides a technical solution: a torque screwdriver with a detection function, comprising an insulating shell 1, a sensor 2, a screwdriver body 3, a card slot 4, a first card block 5, a first spring 6, a mounting slot 7, a bolt 8, a nut 9, a second spring 10, a mounting shell 11, a battery 12, a processor 13, a hook block 14, a second card block 15, a third spring 16 and a storage slot 17.

[0024] When replacing the screwdriver, Figure 1 and Figure 3 As shown, a screwdriver body 3 is provided at the lower end of the sensor 2, and a card slot 4 is provided on the left and right sides of the upper end of the screwdriver body 3, a first card block 5 is connected inside the card slot 4, and a first spring 6 is provided on the right side of the first card block 5, a mounting slot 7 is provided inside the screwdriver body 3, and a bolt 8 is installed inside the mounting slot 7, and a nut 9 is installed at the left end of the bolt 8. First, the nut 9 at the left end of the bolt 8 is removed, and then the bolt 8 is pulled out of the mounting slot 7. At this time, the screwdriver body 3 can be pulled downward, and the screwdriver body 3 drives the card slot 4 to squeeze the first card block 5 when moving. The first card block 5 slides to the left and right sides under the force to squeeze the first spring 6 to contract. After the first card block 5 is completely out of the card slot 4, the screwdriver body 3 is completely disassembled. At this time, the screwdriver body 3 can be replaced according to needs. The above is the process of screw replacement;

[0025] When using the torque screwdriver with detection function, if Figure 1 , Figure 2 and Figure 4 As shown, a second spring 10 is provided at the upper end of the sensor 2, and a mounting shell 11 is provided at the upper end of the second spring 10, and a battery 12 is installed inside the mounting shell 11, a processor 13 is provided at the upper end of the battery 12, and a hook block 14 is fixed to the lower left end of the processor 13, a second card block 15 is connected to the left side of the hook block 14, and a third spring 16 is provided on the left side of the second card block 15. First, when the screwdriver body 3 is tightening the screw, in order to detect whether the screw is tightened, the movement of the screwdriver body 3 is sensed by the sensor 2, and the sensor 2 is then sensed to the processor 13 through other devices at the temporal part of the insulating shell 1, and the processor 13 calculates and finally displays the display at the upper end of the processor 13. On the screen, the display screen lights up to prompt whether the screws are tightened and whether the rotation angle of the screws when connecting to the bones is correct. If the torque-rotation angle ratio of the screws is appropriate before installation, the display screen of the processor 13 on the upper end of the screwdriver will prompt a green light, otherwise it will prompt a red light if the position is inappropriate. Since the screwdriver needs to be used frequently and is not convenient to carry, the second card block 15 can be slid to the left to squeeze the third spring 16, so that the second card block 15 no longer engages with the hook block 14, and the processor 13 quickly drives the hook block 14 to flip open through the torsion spring. At this time, the disassembled screwdriver body 3 can be placed inside the storage slot 17. This is the method of using the torque screwdriver with detection function.
