Description

Technical Field

[0001] This utility model belongs to the field of anastomosis device testing technology, and specifically relates to an anastomosis device full inspection machine. Background Technology

[0002] The stapler inspection machine is a key piece of equipment for ensuring the quality of staplers. It is mainly used for comprehensive inspection of the stapler, accurately checking the condition of the titanium staples within the stapler cartridge, thus preventing serious complications such as postoperative bleeding and anastomotic leakage caused by staple dislodgement or missing staples. Its working principle varies; some devices use image recognition technology to meticulously process the acquired images of the stapler and determine the assembly status of the titanium staples within the cartridge; others use electrical testing contacts that work with the staples to form an equivalent capacitance circuit or switching circuit, detecting the integrity of the staple embedding based on the measured capacitance value or circuit status. The stapler inspection machine boasts high efficiency and accuracy, greatly improving production efficiency, effectively guaranteeing product quality, and strengthening the defense for medical safety.

[0003] Announcement No. "CN221667139U" discloses a cutting stapler activation force detection device, including a detection platform. A positioning plate and a fixing column are fixedly installed on the surface of the detection platform. This cutting stapler activation force detection device, through the inclusion of a control component, uses a hydraulic rod to push a moving block to slide along the inner wall of the fixing column. A bracket fixed to the surface of the moving block drives a support frame to slide. When it descends to a suitable distance, a pressure plate abuts against the surface of the stapler. A vertical rod fixed to the surface of the pressure plate moves upward under the support of a spring. A horizontal rod abuts against the tangent of the moving rod during its movement. The moving rod moves under the support of a spring and engages a locking rod in a slot on the surface of the fixing column. By restricting the downward movement of the bracket through the locking block, this device can handle staplers of different sizes while avoiding excessive force that could damage the stapler.

[0004] While the aforementioned utility model uses a locking block to restrict the downward movement of the support, thus avoiding damage to the stapler due to excessive force applied while handling staplers of different sizes, the irregular shape of the stapler and the fixed structure of the pressure plate in the device prevent it from adaptively adjusting to the curved, protruding, or concave surfaces of the stapler. This results in the pressure plate not fully adhering to the stapler surface. This incomplete fit causes instability in the stapler during testing, leading to displacement or shaking. Consequently, it affects the accurate measurement of the excitation force by the tension sensor, resulting in biased test data that fails to accurately reflect the actual performance of the stapler. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a full inspection machine for staplers.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A stapler inspection machine includes an inspection machine body, a display screen and control buttons installed on one side of the inspection machine body, a moving component installed on the other side of the inspection machine body, a mounting frame installed on one side of the inspection machine body via a moving seat, an electric push rod installed on the top of the mounting frame, a lifting seat fixedly connected to the telescopic end of the electric push rod, an electrical testing contact installed at the bottom of the lifting seat, clamping seats symmetrically slidably connected to the top of the inspection machine body, clamping components symmetrically installed on one side of the clamping seats, and a merging component installed inside the inspection machine body;

[0008] As a preferred technical solution, the clamping assembly includes through holes, clamping posts, positioning blocks, and tension springs. Through holes are symmetrically arranged at equal intervals on one side of the clamping seat. Clamping posts are slidably connected inside the through holes. A positioning block is fixedly connected to one end of each clamping post, and the other end of the clamping post is arc-shaped. A tension spring is fixedly connected to one side of the positioning block, and the other end of the tension spring is fixedly connected to the clamping seat. The tension spring is sleeved on the outside of the clamping post. It can dynamically adjust the clamping force in real time according to the shape and size of different parts of the stapler, ensuring a tight fit at all contact points. This avoids damage to the instrument due to excessive clamping and prevents instability due to insufficient pressure. It achieves precise positioning and stable clamping of irregular staplers in a flexible and adaptive manner, effectively ensuring the stability of the instrument and the reliability of the test results during stapler testing.

[0009] As a preferred technical solution, the clamping end of the clamping column is glued with an anti-slip pad. The surface of the anti-slip pad is provided with anti-slip protrusions. The anti-slip pad is made of soft rubber, which can increase the friction with the surface of the stapler to prevent slippage, and can also avoid damage to the irregular surface of the stapler through its own flexibility, thus achieving the dual effect of stable clamping and instrument protection.

[0010] As a preferred technical solution, the moving component includes a lead screw, a guide rod, a moving block, and a first drive motor. A fixed block is symmetrically fixedly connected to one side of the testing machine body. Guide rods are symmetrically fixedly connected to the fixed blocks, and a lead screw is rotatably connected to each of the fixed blocks. A moving block is sleeved on the outer side of the guide rod and the lead screw. The top of the moving block is fixedly connected to the bottom of the mounting frame. A first drive motor is installed on one side of the fixed block, and the output end of the first drive motor is fixedly connected to the lead screw. The moving block and the lead screw are threaded together, and the moving block and the guide rod are slidably connected. The linear movement of the moving block is controlled by threaded transmission, achieving precise adjustment of the electrical contact position. This converts the rotational motion of the motor into stable linear displacement, resulting in high positioning accuracy. The position of the electrical contact can be adjusted as needed, adapting to various models and structures of staplers. Regardless of the specification of the stapler, the position of the electrical contact can be adjusted to ensure accurate contact with the testing area, improving the versatility and applicability of the equipment.

[0011] As a preferred technical solution, the testing machine body has symmetrically opened limit grooves on one side, and the moving block is symmetrically fixedly connected to the limit block on one side. The limit block and the limit groove are slidably connected. The sliding connection design of the limit block and the limit groove effectively prevents the moving block from deviating or shaking during the movement through precise guidance and positioning, ensuring that the electrical probe moves smoothly and is positioned accurately, thereby improving the stability and reliability of the testing operation.

[0012] As a preferred technical solution, a guide column is fixedly connected to one side of the lifting seat, and guide grooves are symmetrically opened on one side of the mounting frame. A guide block is symmetrically fixedly connected to the other end of the guide column. The guide block and the guide groove are slidably connected. The sliding cooperation of the guide column, guide block and guide groove can provide precise guidance for the relative movement of the lifting seat and the mounting frame, effectively limit the deviation and shaking, ensure the smooth lifting process of the electrical test contact, and ensure the accuracy and stability of the testing operation.

[0013] As a preferred technical solution, the merging assembly includes a cavity, a bidirectional screw, a limiting rod, a merging block, a connecting block, and a second drive motor. The cavity is located inside the testing machine body. A limiting rod is symmetrically fixedly connected to the cavity, and a bidirectional screw is rotatably connected to it. Merging blocks are symmetrically fitted around the limiting rod and the bidirectional screw. A second drive motor is installed on one side of the testing machine body, and its output end is fixedly connected to the bidirectional screw. A connecting block is fixedly connected to the top of the merging block, and the other end of the connecting block extends from the top of the testing machine body and is fixedly connected to the bottom of the clamping seat. The bidirectional screw and the merging block are threadedly connected, while the limiting rod and the merging block are slidably connected. The merging assembly, driven by the second drive motor, moves the bidirectional screw in conjunction with the limiting rod to achieve synchronous and precise movement of the two merging blocks. This ensures that the clamping seat staples the anastomosing device smoothly and symmetrically, effectively improving clamping efficiency and positioning accuracy, and guaranteeing testing stability.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] First, in this utility model, the stapler is placed on the main body of the testing machine, and then the merging assembly is activated to control the movement of the clamping seat. The clamping column on one side of the clamping seat first comes into contact with the surface of the stapler, and then the clamping column slides inside the through hole. At the same time, the clamping column drives the positioning block to move, and the positioning block drives the tension spring to stretch, thereby clamping and fixing the stapler. The clamping force can be dynamically adjusted in real time according to the shape and size of different parts of the stapler to ensure that each contact point is tightly fitted. This can avoid damage to the instrument due to excessive clamping and prevent unstable fixation due to insufficient pressure. The flexible and adaptive method realizes the accurate positioning and stable clamping of irregular staplers, which can effectively ensure the stability of the instrument and the reliability of the test results during the stapler testing process.

[0016] Secondly, in this utility model, the first drive motor is started, controlling the lead screw to rotate. The lead screw and the moving block are driven by a thread, thereby controlling the movement of the moving block. At the same time, the moving block is slidably limited on the outside of the guide rod. The moving block drives the mounting frame to move, and the mounting frame drives the electric push rod and the electrical testing contact to move, thereby adjusting the position of the electrical testing contact. The linear movement of the moving block is controlled by the thread transmission, realizing the precise adjustment of the position of the electrical testing contact. It can convert the rotational motion of the motor into a stable linear displacement, with high positioning accuracy. The position of the electrical testing contact can be adjusted as needed, and it can adapt to various models and structures of staplers. Regardless of the specification of the stapler, the position of the electrical testing contact can be adjusted to ensure accurate contact with the detection part, improving the versatility and applicability of the equipment.
