[0002] Medical devices refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators, materials and other similar or related items that are directly or indirectly used on the human body; medical knives are important tools in medical devices for surgical operations such as cutting, trimming, and piercing; in order to ensure the production quality of medical knives during the current production process, it is usually necessary to test the bending strength of the knives to see if they meet the production requirements. The existing medical knives bending strength test usually uses a three-point bending tester, which places the knife between two support points and applies a concentrated force to the middle of the knife, so that the knife bends between the two points until it breaks. However, during actual use of the knife, the medical knife is held in the hand and the knife head is inserted into the separated object, so that the force point of the knife is concentrated on the blade. The bending test of the three-point bending tester is difficult to simulate the actual use situation, resulting in difficulty in detecting the actual bending strength data of the medical knife. Therefore, a medical device production quality detection device is proposed. Summary of the invention

[0014] A marking pen is fixedly mounted on the connecting frame;

[0015] The inner wall of the second fixing plate is provided with a standard bending arc of a tool, and the rotation track of the marking pen coincides with the standard bending arc of the tool;

[0016] The surgical tool is clamped by the clamping assembly, and the fixing rod rotates along the guiding arc groove. When the contact rod contacts the surgical tool, the contact rod is blocked and retracts into the groove, and pushes the marking pen to contact the inner wall of the first fixing plate.

[0017] Preferably, a rotating shaft is installed between the first fixing plate and the second fixing plate, the rotating shaft is driven by a driving motor, and both ends of the rotating shaft are fixedly connected with docking rods;

The image acquisition device is used to capture whether the arc drawn by the marker pen covers the standard bending arc of the tool. If the surgical tool breaks during the detection process, the surgical tool will be separated from the contact with the contact rod. The contact rod is reset under the action of the first spring sheet, and the writing end of the marker pen does not contact with the inner wall of the first fixed plate. The marker pen will not be able to write on the inner wall of the first fixed plate. The image acquisition device is used to observe and compare the arc written by the marker pen with the arc of the standard bending arc of the tool. If the writing arc cannot cover the standard bending arc of the tool, it means that the surgical tool resistance strength is unqualified. On the contrary, if the writing of the marker pen covers the standard bending arc of the tool, it means that the surgical tool resistance strength is qualified.

[0031] The present invention rotates the rotating shaft and the protrusion follows the rotation synchronously. The thickness of the protrusion pushes the transmission plate to rotate with the hinge between the first fixed plate and the second fixed plate as the central axis. Since the upper end of the transmission plate contacts the movable plate, the movable plate is pushed to move along the transverse groove toward the limit plate through the rotation of the transmission plate to clamp the surgical tool. As the rotating shaft continues to rotate, the protrusion continues to push the pad plate and the transmission plate, while the upper end of the transmission plate is blocked by the movable plate and cannot rotate. At this time, the protrusion pushes the pad plate to compress the second spring sheet to store force, thereby improving the stability of surgical tool detection. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0041] 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.

[0042] like Figures 1 to 8 As shown, the present invention provides a medical device production quality inspection device, including a base 1, and also including:

[0043] A support frame 2 is fixedly mounted on the top of the base 1, and a first fixing plate 3 and a second fixing plate 4 are fixedly mounted on both ends of the support frame 2. The support frame 2, the first fixing plate 3 and the second fixing plate 4 constitute a surgical tool detection cabin;

[0044] The first fixing plate 3 is made of a transparent material;

[0045] A pushing component 5 is arranged in the detection chamber;

[0046] A clamping assembly 6, the clamping assembly 6 is installed between the first fixing plate 3 and the second fixing plate 4;

[0047] A transmission assembly 7, the transmission assembly 7 is arranged between the first fixing plate 3 and the second fixing plate 4 and is used to push the clamping assembly 6 to clamp the surgical tool;

[0048] An image acquisition device 8, which is fixed to the outside of the first fixing plate 3 and is used to analyze surgical tool detection data;

[0049] The pushing assembly 5 includes a fixing rod 51. The first fixing plate 3 and the second fixing plate 4 are provided with a guide arc groove 52. The fixing rod 51 slides in the guide arc groove 52 through two rectangular blocks 522.

[0050] A groove is formed on the outside of the fixing rod 51, and stabilizing plates 512 are fixedly mounted at both ends of the groove. A contact rod 55 is movably disposed inside the groove, and a guide groove for guiding the contact rod 55 is formed on the surface of the stabilizing plate 512.

[0051] One end of the contact rod 55 passes through the guide groove and is connected to a slider 513. One end of the fixed rod 51 is provided with a connecting frame 514. The slider 513 and the connecting frame 514 are connected via a transmission rod 516.

[0052] A marking pen 515 is installed on the connecting frame 514;

[0053] The inner wall of the second fixed plate 4 is provided with a standard bending arc line 54 of the tool, and the rotation track of the marking pen 515 coincides with the standard bending arc line 54 of the tool;

[0054] The surgical tool is clamped by the clamping assembly 6, and the fixing rod 51 rotates along the guiding arc groove 52. When the contact rod 55 contacts the surgical tool, the contact rod 55 is blocked and retracts into the groove, and pushes the marking pen 515 to contact the inner wall of the first fixing plate 3;

[0055] A rotating shaft 524 is installed between the first fixing plate 3 and the second fixing plate 4. The rotating shaft 524 is driven by a driving motor. Both ends of the rotating shaft 524 are fixedly connected with docking rods 523.

[0056] The upper end of the docking rod 523 is movably sleeved with a connecting piece 53;

[0057] Rectangular blocks 522 are fixedly mounted on both ends of the fixing rod 51 . The rectangular blocks 522 are connected to the connecting member 53 . The rectangular blocks 522 move along the guiding arc groove 52 under the action of the driving motor.

[0058] The surgical tool is clamped and fixed by the clamping assembly 6, and the rotating shaft 524, the docking rod 523, the rectangular block 522 and the fixed rod 51 are driven by the driving motor to rotate along the guide arc groove 52. Since the rectangular block 522 is located in the guide arc groove 52, the fixed rod 51 can be prevented from rotating during the rotation process, so that the contact rod 55 cannot contact the surgical tool;

[0059] During the rotation process, the contact rod 55 contacts the surgical tool, and when the contact rod 55 is blocked, it shrinks into the groove to compress the first elastic sheet 511, and pushes the connecting frame 514 and the marking pen 515 to move through the slider 513 and the transmission rod 516, so that the writing end of the marking pen 515 contacts the inner wall of the first fixed plate 3, and the driving motor continuously drives the fixing rod 51 to rotate along the guide arc groove 52, and the contact rod 55 and the fixing rod 51 apply a driving force to the upper end of the surgical tool, so that the surgical tool rotates with the clamping assembly 6 as the central axis, so that the resistance strength of the surgical tool can be tested;

[0060] In the process of pushing the surgical tool by the fixing rod 51 and the contact rod 55, the marking pen 515 contacts and moves with the inner wall of the first fixing plate 3, and draws an arc on the inner wall of the first fixing plate 3, until the fixing rod 51 moves to the other end of the guiding arc groove 52, and the image acquisition device 8 is used to capture whether the arc drawn by the marking pen 515 covers the standard bending arc 54 of the tool. If the surgical tool breaks during the detection process, the surgical tool will be out of contact with the contact rod 55, and the contact rod 55 will be reset under the action of the first spring piece 511, and the writing end of the marking pen 515 will not contact the inner wall of the first fixing plate 3, and the marking pen 515 will not be able to write on the inner wall of the first fixing plate 3. The arc written by the marking pen 515 is observed by the image acquisition device 8 for comparison with the arc of the standard bending arc 54 of the tool. If the writing arc cannot cover the standard bending arc 54 of the tool, it means that the surgical tool resistance strength is unqualified, and conversely, if the writing of the marking pen 515 covers the standard bending arc 54 of the tool, it means that the surgical tool resistance strength is qualified;

[0061] After the surgical tool detection is completed, the driving motor drives the pushing component 5 to move in the reverse direction and reset, the surgical tool is photographed by the image acquisition device 8, and the bending degree of the surgical tool is detected by image comparison.

[0062] like Figure 2 and Figure 3 As shown, a wiping cotton 56 is fixedly mounted on the outside of the fixing rod 51, and the wiping cotton 56 contacts the inner wall of the first fixing plate 3;

[0063] The movement trajectory of the wiping cotton 56 is consistent with that of the marking pen 515.

[0064] When the fixed rod 51 moves along the guide arc groove 52, the wiping cotton 56 wipes the inner wall of the first fixed plate 3 to ensure the clarity of the writing of the marker pen 515, thereby avoiding discontinuity in the writing process of the marker pen 515. The pushing component 5 moves in the opposite direction along the guide arc groove 52, and the wiping cotton 56 wipes the writing marks of the marker pen 515, so that the next tool can be inspected.

[0065] like Figure 3-Figure 5 and Figure 8 As shown, the transmission assembly 7 includes a protrusion 72 fixed to the outside of the rotating shaft 524, and a transmission plate 73 is installed between the first fixed plate 3 and the second fixed plate 4;

[0066] One end of the transmission plate 73 is in a "J" shape and is located outside the rotating shaft 524, and the other end of the transmission plate 73 is in contact with the clamping assembly 6;

[0067] A pad 74 is provided on the inner wall of one end of the transmission plate 73, and the pad 74 is pressed on the outside of the protrusion 72;

[0068] The protrusion 72 rotates, and gradually pushes the transmission plate 73 to rotate about the central axis due to its own thickness;

[0069] The backing plate 74 and the transmission plate 73 are connected via a second elastic sheet 71;

[0070] The protrusion 72 rotates to push the backing plate 74 and the second elastic sheet 71 to rotate the transmission plate 73, and the upper end of the transmission plate 73 is blocked by the clamping assembly 6. At this time, the protrusion 72 pushes the backing plate 74 to compress the second elastic sheet 71 to store force;

[0071] The clamping assembly 6 includes a limiting plate 61 fixed between the first fixed plate 3 and the second fixed plate 4. A transverse groove is provided on the opposite surfaces of the first fixed plate 3 and the second fixed plate 4. A movable plate 62 slides in the transverse groove. Stabilizing pads 63 are provided on the opposite surfaces of the limiting plate 61 and the movable plate 62. A supporting plate 64 is fixed on the bottom of the limiting plate 61.

[0072] The surgical tool is placed between the limit plate 61 and the movable plate 62, and the two stabilizing pads 63 are used to stably position the tool between the limit plate 61 and the movable plate 62. The rotating shaft 524 is driven by the driving motor to rotate, and the protrusion 72 rotates synchronously. The thickness of the protrusion 72 drives the transmission plate 73 to rotate around the hinge between the first fixed plate 3 and the second fixed plate 4. Since the upper end of the transmission plate 73 contacts the movable plate 62, the transmission plate 73 rotates to push the movable plate 62 to move along the transverse groove toward the limit plate 61 to achieve the purpose of clamping the surgical tool.

[0073] As the rotating shaft 524 continues to rotate, the protrusion 72 continues to push the pad 74 and the transmission plate 73, and the upper end of the transmission plate 73 is blocked by the movable plate 62 and cannot rotate. At this time, the protrusion 72 pushes the pad 74 to compress the second spring sheet 71 to store force, thereby improving the stability of the surgical tool detection.

[0074] The working principle and use process of the present invention:

[0075] The surgical tool is placed between the limit plate 61 and the movable plate 62, and the two stabilizing pads 63 are used to stably position the tool between the limit plate 61 and the movable plate 62. The rotating shaft 524 is driven by the driving motor to rotate, and the protrusion 72 rotates synchronously. The thickness of the protrusion 72 drives the transmission plate 73 to rotate around the hinge between the first fixed plate 3 and the second fixed plate 4. Since the upper end of the transmission plate 73 contacts the movable plate 62, the transmission plate 73 rotates to push the movable plate 62 to move along the transverse groove toward the limit plate 61 to achieve the purpose of clamping the surgical tool.

[0076] As the rotating shaft 524 continues to rotate, the protrusion 72 continues to push the pad 74 and the transmission plate 73, and the upper end of the transmission plate 73 is blocked by the movable plate 62 and cannot rotate. At this time, the protrusion 72 pushes the pad 74 to compress the second elastic sheet 71 to store force, thereby improving the stability of the detection of the surgical tool;

[0077] The driving motor drives the rotating shaft 524, the docking rod 523, the rectangular block 522 and the fixed rod 51 to rotate along the guide arc groove 52. Since the rectangular block 522 is located in the guide arc groove 52, the fixed rod 51 can be prevented from rotating during the rotation process, so that the contact rod 55 cannot contact the surgical tool.

[0078] During the rotation process, the contact rod 55 contacts the surgical tool, and when the contact rod 55 is blocked, it shrinks into the groove to compress the first elastic sheet 511, and pushes the connecting frame 514 and the marking pen 515 to move through the slider 513 and the transmission rod 516, so that the writing end of the marking pen 515 contacts the inner wall of the first fixed plate 3, and the driving motor continuously drives the fixing rod 51 to rotate along the guide arc groove 52, and the contact rod 55 and the fixing rod 51 apply a driving force to the upper end of the surgical tool, so that the surgical tool rotates with the clamping assembly 6 as the central axis, so that the resistance strength of the surgical tool can be tested;

[0079] In the process of pushing the surgical tool by the fixing rod 51 and the contact rod 55, the marking pen 515 contacts and moves with the inner wall of the first fixing plate 3, and draws an arc on the inner wall of the first fixing plate 3, until the fixing rod 51 moves to the other end of the guiding arc groove 52, and the image acquisition device 8 is used to capture whether the arc drawn by the marking pen 515 covers the standard bending arc 54 of the tool. If the surgical tool breaks during the detection process, the surgical tool will be out of contact with the contact rod 55, and the contact rod 55 will be reset under the action of the first spring piece 511, and the writing end of the marking pen 515 will not contact the inner wall of the first fixing plate 3, and the marking pen 515 will not be able to write on the inner wall of the first fixing plate 3. The arc written by the marking pen 515 is observed by the image acquisition device 8 for comparison with the arc of the standard bending arc 54 of the tool. If the writing arc cannot cover the standard bending arc 54 of the tool, it means that the surgical tool resistance strength is unqualified, and conversely, if the writing of the marking pen 515 covers the standard bending arc 54 of the tool, it means that the surgical tool resistance strength is qualified;

[0080] After the surgical tool detection is completed, the driving motor drives the push assembly 5 to move in the reverse direction and reset, and the surgical tool is photographed by the image acquisition device 8, and the bending degree of the surgical tool is detected by image comparison;

[0081] When the fixed rod 51 moves along the guide arc groove 52, the wiping cotton 56 wipes the inner wall of the first fixed plate 3 to ensure the clarity of the writing of the marker pen 515, thereby avoiding discontinuity in the writing process of the marker pen 515. The pushing component 5 moves in the opposite direction along the guide arc groove 52, and the wiping cotton 56 wipes the writing marks of the marker pen 515, so that the next tool can be inspected.
