Description

Technical Field

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

[0002] Medical devices refer to instruments, equipment, utensils, 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; currently, during the production process of medical knives, in order to ensure their production quality, it is usually necessary to detect the anti-bending strength of the knives to see if they meet the production requirements. Currently, the anti-bending strength of existing medical knives is usually detected using a three-point bending testing machine. The knife is placed between two support points, and a concentrated force is applied in the middle of the knife, causing the knife to bend between the two points until it breaks. However, when holding a medical knife during actual use and inserting the knife tip into a separated object, the force-bearing point of the knife is concentrated on the blade. The bending test of the three-point bending testing machine is difficult to simulate the actual use situation, resulting in difficulty in detecting the actual anti-bending strength data of the medical knife. Therefore, a device for detecting the production quality of medical devices is proposed. Summary of the Invention

[0003] To solve the problems raised in the above background art, the present invention provides a device for detecting the production quality of medical devices, which solves the problem that the bending test of the existing three-point bending testing machine is difficult to simulate the actual use situation, resulting in difficulty in detecting the actual anti-bending strength data of medical knives.

[0004] To achieve the above object, the present invention provides the following technical solution: A device for detecting the production quality of medical devices, including a base, and further including:

[0005] A support frame is fixedly installed on the top of the base. At both ends inside the support frame, a first fixed plate and a second fixed plate are fixedly installed. The support frame, the first fixed plate, and the second fixed plate form a surgical knife detection chamber;

[0006] The first fixed plate is made of a transparent material;

[0007] A pushing component, which is arranged inside the detection chamber;

[0008] A clamping component, which is installed between the first fixed plate and the second fixed plate;

[0009] A transmission component, which is arranged between the first fixed plate and the second fixed plate and is used to push the clamping component to clamp the surgical knife;

[0010] An image acquisition device, which is fixedly installed outside the first fixed plate and is used to analyze the surgical knife detection data;

[0011] Among them, the pushing component includes a fixed rod. Guide arc grooves are formed on the first fixing plate and the second fixing plate. The fixed rod slides in the guide arc grooves through two rectangular blocks;

[0012] A groove is formed on the outer part of the fixed rod. Stabilizing plates are fixedly installed at both ends of the groove. A contact rod is movably arranged inside the groove. Guide grooves for guiding the contact rod are formed on the surfaces of the stabilizing plates;

[0013] One end of the contact rod penetrates through the guide groove and is connected with a slider. A connecting frame is arranged at one end of the fixed rod. The slider and the connecting frame are connected through a transmission rod;

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

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

[0016] The surgical tool is clamped by a clamping component. The fixed rod rotates along the guide arc groove. When the contact rod contacts the surgical tool, the contact rod is blocked and contracts 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. Docking rods are fixedly connected to both ends of the rotating shaft;

[0018] A connecting piece is movably sleeved on the upper end of the docking rod.

[0019] Preferably, rectangular blocks are fixedly installed at both ends of the fixed rod. The rectangular blocks are connected with the connecting piece. The rectangular blocks move along the guide arc groove under the action of the driving motor.

[0020] Preferably, a wiping cotton is fixedly installed on the outer part of the fixed rod. The wiping cotton contacts the inner wall of the first fixing plate;

[0021] The wiping cotton has the same movement trajectory as the marking pen.

[0022] Preferably, the transmission component includes a convex block fixedly installed on the outer part of the rotating shaft. A transmission plate is installed between the first fixing plate and the second fixing plate;

[0023] One end of the transmission plate is in a "J" shape and is located on the outer part of the rotating shaft. The other end of the transmission plate abuts against the clamping component.

[0024] Preferably, a cushion plate is arranged on the inner wall of one end of the transmission plate. The cushion plate presses on the outer part of the convex block;

[0025] The bump rotates and gradually pushes the transmission plate to rotate around the central axis under the action of its own thickness.

[0026] Preferably, the backing plate and the transmission plate are connected by a second elastic sheet;

[0027] The rotation of the bump pushes the backing plate and the second elastic sheet to make the transmission plate rotate. However, the upper end of the transmission plate is blocked by the clamping assembly. At this time, the bump pushes the backing plate to compress the second elastic sheet to store energy.

[0028] Preferably, the clamping assembly includes a limiting plate fixedly installed between the first fixing plate and the second fixing plate. Transverse grooves are formed on the opposite surfaces of the first fixing plate and the second fixing plate. A movable plate slides in the transverse grooves. Stable pads are arranged on the opposite surfaces of the limiting plate and the movable plate. A supporting plate is fixedly installed at the bottom of the limiting plate.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0030] In the present invention, the surgical tool is pushed by the fixing rod and the contact rod. The marker pen contacts and moves along the inner wall of the first fixing plate, and draws an arc on the inner wall of the first fixing plate until the fixing rod moves to the other end of the guiding arc groove. Whether the arc drawn by the marker pen covers the standard bending arc of the tool is photographed by the image acquisition device. If the surgical tool breaks during the detection process, the surgical tool will be separated from the contact with the contact rod. Under the action of the first elastic sheet, the contact rod resets, and the writing end of the marker pen does not contact the inner wall of the first fixing plate, and the marker pen will not be able to write on the inner wall of the first fixing plate. By observing the arc of the marker pen writing arc and the tool standard bending arc through the image acquisition device for comparison, if the writing arc cannot cover the tool standard bending arc, it means that the anti-strength of the surgical tool is unqualified. On the contrary, if the marker pen writing covers the tool standard bending arc, it means that the anti-strength of the surgical tool is qualified;

[0031] In the present invention, the rotating shaft rotates, and the bump rotates synchronously. The thickness of the bump is used to push the transmission plate to rotate around the hinge joint of the first fixing plate and the second fixing plate as the central axis. Since the upper end of the transmission plate abuts against the movable plate, the rotation of the transmission plate is used to push the movable plate to move along the transverse groove towards the limiting plate to clamp the surgical tool. As the rotating shaft continues to rotate, the bump continuously pushes the backing plate and the transmission plate. However, the upper end of the transmission plate is blocked by the movable plate and cannot rotate. At this time, the bump pushes the backing plate to compress the second elastic sheet to store energy, thereby improving the stability of the detection of the surgical tool.

Specific embodiments

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

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

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

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

[0045] The pushing component 5 is arranged inside the detection chamber;

[0046] The clamping component 6 is installed between the first fixing plate 3 and the second fixing plate 4;

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

[0048] The image acquisition device 8 is fixedly installed outside the first fixing plate 3 and is used to analyze the detection data of the surgical tool;

[0049] Among them, the pushing component 5 includes a fixing rod 51. Guide arc grooves 52 are formed on the first fixing plate 3 and the second fixing plate 4. The fixing rod 51 slides in the guide arc grooves 52 through two rectangular blocks 522;

[0050] A groove is formed on the outer portion of the fixing rod 51. Stabilizing plates 512 are fixedly installed at both ends of the groove respectively. A contact rod 55 is movably arranged inside the groove. Guide grooves for guiding the contact rod 55 are formed on the surfaces of the stabilizing plates 512;

[0051] One end of the contact rod 55 penetrates through the guide groove and is connected with a slider 513. A connecting frame 514 is arranged at one end of the fixing rod 51. The slider 513 and the connecting frame 514 are connected through a transmission rod 516;

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

[0053] A tool standard bending arc 54 is arranged on the inner wall of the second fixing plate 4. The rotation trajectory of the marking pen 515 coincides with the tool standard bending arc 54;

[0054] The surgical tool is clamped by the clamping component 6. When the fixing rod 51 rotates along the guide arc groove 52 and the contact rod 55 contacts the surgical tool, the contact rod 55 is blocked and contracts 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. Docking rods 523 are fixedly connected to both ends of the rotating shaft 524;

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

[0057] Rectangular blocks 522 are fixedly installed at both ends of the fixing rod 51. The rectangular blocks 522 are connected with the connecting piece 53. The rectangular blocks 522 move along the guide arc groove 52 under the action of the driving motor.

[0058] The surgical tool is clamped and fixed by the clamping assembly 6. The drive motor drives the rotating shaft 524, the docking rod 523, the rectangular block 522 and the fixed rod 51 to rotate along the guiding arc groove 52. Since the rectangular block 522 is located in the guiding arc groove 52, it can prevent the fixed rod 51 from rotating during the rotation process, resulting in the contact rod 55 being unable to contact the surgical tool;

[0059] During the rotation process, the contact rod 55 contacts the surgical tool. When the contact rod 55 is blocked, it contracts into the groove to compress the first elastic piece 511, and through the slider 513 and the transmission rod 516, it pushes the connecting frame 514 and the marker pen 515 to move, so that the writing end of the marker pen 515 contacts the inner wall of the first fixing plate 3. The drive motor continuously drives the fixed rod 51 to rotate along the guiding arc groove 52. By applying a driving force to the upper end of the surgical tool through the contact rod 55 and the fixed rod 51, the surgical tool rotates with the clamping assembly 6 as the axis, and the anti-strength of the surgical tool can be detected;

[0060] During the process of pushing the surgical tool by the fixed rod 51 and the contact rod 55, the marker pen 515 contacts and moves along 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 fixed rod 51 moves to the other end of the guiding arc groove 52. The image acquisition device 8 is used to photograph whether the arc drawn by the marker pen 515 covers the tool standard bending arc 54. If the surgical tool breaks during the detection process, the surgical tool will be separated from the contact with the contact rod 55. Under the action of the first elastic piece 511, the contact rod 55 resets, and the writing end of the marker pen 515 does not contact the inner wall of the first fixing plate 3, and the marker pen 515 will not be able to write on the inner wall of the first fixing plate 3. By observing the arc of the writing arc of the marker pen 515 and the tool standard bending arc 54 through the image acquisition device 8 for comparison, if the writing arc cannot cover the tool standard bending arc 54, it means that the anti-strength of the surgical tool is unqualified. On the contrary, if the writing of the marker pen 515 covers the tool standard bending arc 54, it means that the anti-strength of the surgical tool is qualified;

[0061] After the detection of the surgical tool is completed, the drive motor drives the pushing assembly 5 to move backward and reset, and the image acquisition device 8 is used to photograph the surgical tool, and the bending degree of the surgical tool is detected through image comparison.

[0062] As Figure 2 shown, a wiping cotton 56 is fixedly installed on the outside of the fixed rod 51, and the wiping cotton 56 contacts the inner wall of the first fixing plate 3; Figure 3 The wiping cotton 56 has the same movement track as the marker pen 515.

[0063] The wiping cotton 56 has the same movement track as the marker pen 515.

[0064] During the movement of the fixed rod 51 along the guiding arc groove 52, the wiping cotton 56 wipes the inner wall of the first fixing plate 3, ensuring the clarity of the writing of the marker pen 515, thereby avoiding the intermittent situation during the writing of the marker pen 515. When the pushing component 5 moves reversely along the guiding arc groove 52, the wiping cotton 56 wipes the writing trace of the marker pen 515, and then the next tool can be detected.

[0065] As Figures 3 to 5 shown in Figure 8 Figure, the transmission component 7 includes a convex block 72 fixedly installed outside the rotating shaft 524, and a transmission plate 73 is installed between the first fixing plate 3 and the second fixing 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 abuts against the clamping component 6;

[0067] A backing plate 74 is arranged on the inner wall of one end of the transmission plate 73, and the backing plate 74 presses on the outside of the convex block 72;

[0068] When the convex block 72 rotates, it gradually pushes the transmission plate 73 to rotate around the central axis under the action of its own thickness;

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

[0070] When the convex block 72 rotates to push the backing plate 74 and the second elastic piece 71 to make the transmission plate 73 rotate, and the upper end of the transmission plate 73 is blocked by the clamping component 6, at this time, the convex block 72 pushes the backing plate 74 to compress the second elastic piece 71 to store energy;

[0071] The clamping component 6 includes a limiting plate 61 fixedly installed between the first fixing plate 3 and the second fixing plate 4. Transverse grooves are formed on the opposite surfaces of the first fixing plate 3 and the second fixing plate 4. A movable plate 62 slides in the transverse grooves. Stable pads 63 are arranged on the opposite surfaces of the limiting plate 61 and the movable plate 62, and a support plate 64 is fixedly installed at the bottom of the limiting plate 61.

[0072] Place the surgical tool between the limiting plate 61 and the movable plate 62, and make the tool stably located between the limiting plate 61 and the movable plate 62 through the two stable pads 63. Drive the rotating shaft 524 to rotate through the driving motor, and the convex block 72 rotates synchronously. The thickness of the convex block 72 is used to push the transmission plate 73 to rotate around the hinge joint of the first fixing plate 3 and the second fixing plate 4 as the central axis. Since the upper end of the transmission plate 73 abuts against the movable plate 62, the rotation of the transmission plate 73 is used to push the movable plate 62 to move along the transverse groove towards the limiting plate 61 to achieve the purpose of clamping the surgical tool;

[0073] As the rotating shaft 524 continues to rotate, the convex block 72 continuously pushes the backing plate 74 and the transmission plate 73. However, the upper end of the transmission plate 73 is blocked by the movable plate 62 and cannot rotate. At this time, the convex block 72 pushes the backing plate 74 to compress the second elastic piece 71 to store energy, thereby improving the stability of the detection of the surgical tool.

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

[0075] Place the surgical tool between the limiting plate 61 and the movable plate 62, and make the tool stably located between the limiting plate 61 and the movable plate 62 through two stabilizing pads 63. Drive the rotating shaft 524 to rotate through the driving motor, and the convex block 72 rotates synchronously. Push the transmission plate 73 to rotate around the hinge joint of the first fixing plate 3 and the second fixing plate 4 through the thickness of the convex block 72. Since the upper end of the transmission plate 73 abuts against the movable plate 62, push the movable plate 62 to move along the transverse groove towards the limiting plate 61 through the rotation of the transmission plate 73 to achieve the purpose of clamping the surgical tool;

[0076] As the rotating shaft 524 continues to rotate, the convex block 72 continuously pushes the backing plate 74 and the transmission plate 73. However, the upper end of the transmission plate 73 is blocked by the movable plate 62 and cannot rotate. At this time, the convex block 72 pushes the backing plate 74 to compress the second elastic piece 71 to store energy, thereby improving the stability of the detection of the surgical tool;

[0077] Drive the rotating shaft 524, the docking rod 523, the rectangular block 522 and the fixed rod 51 to rotate along the guiding arc groove 52 through the driving motor. Since the rectangular block 522 is located in the guiding arc groove 52, it can prevent the fixed rod 51 from rotating during the rotation process, resulting in the contact rod 55 being unable to contact the surgical tool;

[0078] During the rotation process, the contact rod 55 contacts the surgical tool. When the contact rod 55 is blocked, it contracts into the groove to compress the first elastic piece 511, and pushes the connecting frame 514 and the marker pen 515 to move through the slider 513 and the transmission rod 516, so that the writing end of the marker pen 515 contacts the inner wall of the first fixing plate 3. And the driving motor continuously drives the fixed rod 51 to rotate along the guiding arc groove 52. Apply a driving force to the upper end of the surgical tool through the contact rod 55 and the fixed rod 51, so that the surgical tool rotates around the clamping assembly 6, and the anti-strength of the surgical tool can be detected;

[0079] During the process of pushing the surgical tool by the fixing rod 51 and the contact rod 55, the marker pen 515 moves in contact with the inner wall of the first fixing plate 3, drawing 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. The image acquisition device 8 is used to capture whether the arc drawn by the marker 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 separated from the contact with the contact rod 55. Under the action of the first elastic piece 511, the contact rod 55 resets, and the writing end of the marker pen 515 does not contact the inner wall of the first fixing plate 3, so the marker pen 515 will not be able to write on the inner wall of the first fixing plate 3. By observing the arc of the writing arc of the marker pen 515 and the standard bending arc 54 of the tool through the image acquisition device 8 and comparing them, if the writing arc cannot cover the standard bending arc 54 of the tool, it means that the anti-strength of the surgical tool is unqualified. On the contrary, if the writing of the marker pen 515 covers the standard bending arc 54 of the tool, it means that the anti-strength of the surgical tool is qualified;

[0080] After the detection of the surgical tool is completed, the driving motor drives the pushing assembly 5 to move back and reset, and the image acquisition device 8 is used to take pictures of the surgical tool, and the bending degree of the surgical tool is detected through image comparison;

[0081] During the movement of the fixing rod 51 along the guiding arc groove 52, the wiping cotton 56 wipes the inner wall of the first fixing plate 3 to ensure the clarity of the writing of the marker pen 515, thus avoiding the situation of intermittent writing during the writing of the marker pen 515. When the pushing assembly 5 moves in the reverse direction along the guiding arc groove 52, the wiping cotton 56 wipes the writing trace of the marker pen 515, and then the detection of the next tool can be carried out.

[0082] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0083] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
