Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a quality inspection device for medical device production. Background Art

[0002] Medical devices refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators, materials and other similar or related items used directly or indirectly on the human body.

[0003] For example, a medical device production quality inspection device with publication number CN119198331A pushes the surgical tool through the fixed rod and the contact rod, and the marker moves in contact with the inner wall of the first fixed plate, drawing an arc on the inner wall of the first fixed plate until the fixed rod moves to the other end of the guide arc groove. The image acquisition device is used to capture whether the arc drawn by the marker covers the standard bending arc of the tool. If the surgical tool breaks during the inspection process, the surgical tool will be out of contact with the contact rod. Under the action of the first spring piece, the contact rod is reset, and the writing end of the marker does not contact the inner wall of the first fixed plate. The marker will not be able to write on the inner wall of the first fixed plate, and the arc written by the marker is observed by the image acquisition device. Compare the arc of the marker pen with the arc of the standard bending arc of the tool. If the written arc cannot cover the standard bending arc of the tool, it means that the surgical tool resistance is unqualified. On the contrary, if the marker pen covers the standard bending arc of the tool, it means that the surgical tool resistance is qualified. However, in actual use, for example, when testing orthopedic implants such as bone plates and bone screws, in order to ensure the reliability after implantation, it is necessary to reverse test such instruments to test the torsional resistance of such instruments. When testing scalpels or surgical hammers, it is necessary to perform compression testing on the force points. When facing different types of medical devices, different testing equipment is required for testing. The overall applicability is poor and there are certain defects in use.

[0027] By adopting the above technical solution, it is convenient to adjust the supporting force position of the device.

[0028] Compared with the prior art, the present invention has the following beneficial effects: the quality inspection device for medical device production allows the inspection method to be adjusted according to the type of device. When performing a compression test on the device, the device does not need to be fixed, thereby avoiding the impact of subsequent compression tests on the inspection accuracy due to the fixing of both ends of the device. When performing a torsion test on the device, one end of the device can be fixed, facilitating subsequent torsion testing of the device. Different fixing methods can be used for the device according to different inspection methods, thereby improving practicality.

[0029] 1. When performing a pressure test on an instrument, the instrument can be placed on two placement racks, and then the hydraulic cylinder can be started to drive the movable plate downward, so that the detection rack can be driven to press the instrument downward. The downward pressure of the detection rack can be known through the pressure sensor, and the drive motor can be started according to different medical instruments to drive the screw to rotate, so that the detection rack can be driven to move, and different positions of the instrument can be tested. When performing a torsion test on the instrument, the movement of the detection rack can perform torsion test on different positions of the instrument. When performing a torsion test, the electric push rod is started to drive the connecting seat to move, so that the connecting rod can be driven to rotate. After the connecting rod rotates, the two splints can be driven to slide on the vertical pole and approach each other. The splints are made of rubber plates, so that the two splints can clamp the instrument, so that one end of the rotating rack is fixed, and the movable plate is moved up, so that the connecting plate can be driven up. The connecting rope is made of wire rope, which can be used. By pulling one end of the rotating frame upward through the connecting rope, the other end of the rotating frame is fixed to the instrument, thereby driving the rotating frame to rotate, so that the instrument can be twisted, and during the rotation of the rotating frame, the movable sleeve is driven to slide on the arc frame and stretch the telescopic spring, and the movable sleeve and the arc frame are clearance-matched. Before performing the torsion detection, the reading of the tension sensor can be observed before the instrument is twisted. After the rotating frame rotates and drives the instrument to twist, the value on the tension sensor can reach the specified detection range to perform the torsion detection, so that the detection method can be adjusted according to the type of instrument. When performing the pressure resistance test on the instrument, the instrument will not be fixed, avoiding the influence of the detection accuracy of the subsequent pressure resistance test due to the fixing of both ends of the instrument, and when performing the torsion test on the instrument, one end of the instrument can be fixed, which is convenient for the subsequent torsion test of the instrument. Different fixing methods can be used for the instrument according to different detection methods, thereby improving practicality.

[0030] 2. During the torsion test of the instrument, when the rotating frame starts to rotate, the mounting seat is stuck on the outside of the instrument, and then the mounting seat will not easily detach from the instrument, so that the connecting rope pulls the rotating frame to rotate. When the rotating frame rotates, it first drives the mounting sleeve to rotate in a circle. The elastic coefficient of the supporting spring is greater than the elastic coefficient of the two sets of tension springs, so that the rotating frame can drive the swing rod to rotate in a circle during the rotation process, and then drive the rotating rod to rotate. After the rotating rod rotates, it drives the turntable to rotate. After the turntable rotates, the column block abuts against the positioning plate, so that the rotation of the turntable can push the positioning plate to move. The cam is moved to move the sliding rod on the mounting block and stretch the tension spring, thereby enabling the two positioning plates to clamp the instrument, so that one end of the instrument can be positioned, and then the clamping plate can clamp and fix the instrument. At this time, the rotating frame rotates, which can drive the mounting frame to slide outside the arc rod. The mounting frame and the arc rod are intermittently matched, and the axes of the arc rod and the arc frame coincide with the center of the mounting seat. In the subsequent detection process, the rotating frame continues to rotate and will no longer drive the swing rod to rotate, so that a torsional force can be applied to the instrument, which is convenient for torsional detection of the instrument and improves practicality.

[0031] 3. When performing a compression test on the instrument, the movable block can be pulled down to drive the positioning rod to slide on the placement rack, so that the positioning rod is disengaged from the positioning slot, and the placement rack loses its limit. The position of the placement rack can be adjusted. After adjustment, the positioning rod is aligned with another positioning slot, and then the movable block is released. Under the action of the reset spring, the positioning rod is engaged with the positioning slot, so that the placement rack is positioned, and then the position of the placement rack can be adjusted. Then, when performing a compression test, the support point of the instrument can be adjusted, which is convenient for adjusting the test position according to the main force point of the instrument. When performing a torsion test, the left placement rack is moved to the leftmost side. After the instrument is placed, the instrument will not contact the right placement rack. At this time, it is convenient to perform a torsion test on the instrument, thereby improving practicality. BRIEF DESCRIPTION OF THE DRAWINGS

While the rotating frame 217 rotates, it first drives the mounting sleeve 227 to rotate in a circle.

Therefore, during the subsequent detection process, the rotating frame 217 continues to rotate and will no longer drive the swing rod 231 to rotate, so that a torsional force can be applied to the instrument, which facilitates torsion detection of the instrument and improves practicality.

[0061] Working principle: When using the quality inspection device for medical device production, first, according to Figures 1-10As shown, when the pressure resistance test of the instrument is performed, the instrument can be placed on the two placement racks 201, and then the hydraulic cylinder 103 can be started to drive the movable plate 104 to move downward, so that the detection rack 207 can be driven to press the instrument downward. The downward pressure of the detection rack 207 can be known through the pressure sensor 208, and the driving motor can be started according to different medical instruments to drive the screw 2072 to rotate, so that the detection rack 207 can be driven to move, and different positions of the instrument can be tested. When the instrument is subjected to torsion testing, the movement of the detection rack 207 can perform torsion testing on different positions of the instrument. When performing torsion testing, the electric push rod 226 is started to drive the connecting seat 225 to move, so that the connecting rod 224 can be driven to rotate. After the connecting rod 224 rotates, the two splints 222 can be driven to slide on the vertical rod 221 and approach each other. The splint 222 is made of rubber. The rubber plate allows the two clamping plates 222 to clamp the instrument, so that one end of the rotating frame 217 is fixed, and the movable plate 104 is moved up, so that the connecting plate 209 can be driven to move up. The connecting rope 218 is a steel wire rope, and then the connecting rope 218 can be used to pull one end of the rotating frame 217 to move up, and one end of the rotating frame 217 is fixed to the instrument, which can drive the rotating frame 217 to rotate, so that the instrument can be twisted. During the rotation of the rotating frame 217, the movable sleeve 216 is driven to slide on the arc frame 215 and stretch the telescopic spring 2161. The movable sleeve 216 and the arc frame 215 are clearance-matched. Before performing the torsion test, the reading of the tension sensor 219 can be observed before the instrument is twisted. After the rotating frame 217 rotates and drives the instrument to twist, the value on the tension sensor 219 can reach the specified detection range, and the torsion test is performed;

[0062] During the torsion detection process of the instrument, when the rotating frame 217 starts to rotate, the mounting seat 220 is stuck on the outside of the instrument, and then the mounting seat 220 will not easily detach from the instrument, so that the connecting rope 218 pulls the rotating frame 217 to rotate. When the rotating frame 217 rotates, it first drives the mounting sleeve 227 to rotate in a circle. The elastic coefficient of the support spring 229 is greater than the elastic coefficient of the two sets of tension springs 240, so that the rotating frame 217 can drive the swing rod 231 to rotate in a circle during the rotation process, and then drive the rotating rod 233 to rotate. After the rotating rod 233 rotates, it drives The turntable 235 rotates, and after the turntable 235 rotates, the column block 236 abuts against the positioning plate 241, so that the rotation of the turntable 235 can push the positioning plate 241 to move, so that the sliding rod 238 slides on the mounting block 237 and stretches the tension spring 240, thereby enabling the two positioning plates 241 to clamp the instrument, so that one end of the instrument can be positioned, and then the clamping plate 222 clamps the instrument. At this time, the rotating frame 217 rotates, which can drive the mounting frame 230 to slide outside the arc rod 228. The mounting frame 230 and the arc rod 228 are intermittently connected. The axes of the arc rod 228 and the arc frame 215 coincide with the center of the mounting seat 220, and in the subsequent detection process, the rotating frame 217 continues to rotate and will no longer drive the swing rod 231 to rotate, so that a torsional force can be applied to the instrument, which is convenient for torsional detection of the instrument and improves practicality. When the instrument is subjected to pressure resistance detection, the movable block 306 can be pulled down to drive the positioning rod 303 to slide on the placement frame 201, so that the positioning rod 303 is disengaged from the positioning groove 305, so that the placement frame 201 loses its limit, and the position of the placement frame 201 can be adjusted. After adjustment, the positioning rod 303 03 is aligned with another positioning groove 305, and then the movable block 306 is loosened. Under the action of the reset spring 304, the positioning rod 303 is engaged with the positioning groove 305, so that the placement rack 201 is positioned, and then the position of the placement rack 201 can be adjusted. Then, when performing a compression test, the support point of the instrument can be adjusted, which is convenient for adjusting the test position according to the main force point of the instrument. When performing a torsion test, the left placement rack 201 is moved to the leftmost side. After the instrument is placed, the instrument will not contact the right placement rack 201. At this time, it is convenient to perform a torsion test on the instrument, which improves practicality.
