[0013] The present invention further provides a method for detecting a puncture and insertion device, including the above-mentioned puncture and insertion device detection apparatus, comprising the following steps:

[0014] Step 1: Place the puncture needle to be tested on the left side of the movable upright plate and start the drive motor. The output end of the drive motor drives the first rotating gear to rotate. The first rotating gear meshes with the ring rack and rotates. The ring rack and rotates, driving the pull rod and the pull column to pull the movable horizontal plate inward. The movable horizontal plate drives the compression spring column and the arc-shaped clamping plate inward. Utilizing the elasticity of the compression spring column, the right side of the puncture needle is stably and appropriately clamped and fixed to ensure that the puncture needle will not be displaced during the testing process.

[0015] Step 2: According to the testing requirements, place the puncture simulation tissue inside the clamping and fixing device, start the rotating motor, the output end of the rotating motor drives the drive gear to rotate, the drive gear meshes with the half gear to drive the linkage rod to move, the linkage rod drives the arc-shaped clamping block to move inward to clamp and fix the puncture simulation tissue, then start the first electric telescopic rod, the output end of the first electric telescopic rod drives the rack plate to move, the rack plate meshes with the second rotating gear to drive the rotating cross column and the swing block to rotate forward to the horizontal direction, then start the second electric telescopic rod, the output end of the second electric telescopic rod drives the clamping and fixing device and the puncture simulation tissue to the position corresponding to the puncture needle and then stops;

[0016] Step 3: Then start the high-pressure air pump. The high-pressure air pump delivers high-pressure gas through the output end to the diverter tube, and then through the diverter tube to the telescopic cylinder. The telescopic cylinder drives the moving plate and the puncture needle to move to the left, so that the puncture needle is inserted into the puncture simulated tissue for puncture force detection. The force sensor records the force data when the puncture needle is inserted, thus completing the puncture force detection.

[0017] Step 4: After the test is completed, remove the puncture simulated tissue from the clamping and fixing device. Control the telescopic cylinder to move the moving plate and puncture needle to the right and reset. Place the puncture needle sheath inside the clamping and fixing device. Start the rotating motor. The output end of the rotating motor drives the drive gear to rotate. The drive gear meshes with the half gear to drive the linkage rod to move. The linkage rod drives the arc-shaped clamping block to move inward to clamp and fix the surface of the puncture needle sheath.

[0018] Step 5: Then, control the high-pressure air pump to drive the telescopic cylinder to move to the left. The telescopic cylinder drives the moving plate and the puncture needle to be inserted into the puncture needle cannula. Then, control the telescopic cylinder to move in the opposite direction. The telescopic cylinder drives the moving plate and the puncture needle to be pulled out inside the puncture needle cannula. This is used to detect the insertion force and the withdrawal force. At the same time, the force sensor records the force data when pulling out. By comparing the insertion force and withdrawal force data, the fit performance between the puncture needle and the cannula is evaluated.

[0019] Step 6: After the test is completed, remove the puncture needle cannula from the clamping and fixing device, control the second electric telescopic rod to drive the clamping and fixing device to retract to the rear, and then the high-pressure air pump drives the telescopic cylinder to move to the left. The telescopic cylinder drives the moving upright plate and the puncture needle to move to the left, so that the puncture needle is inserted into the inside of the sealing cylinder, creating conditions for the sealing performance test.

[0020] Step 7: Then start the electric push rod. The output end of the electric push rod drives the push bracket to move. The push bracket drives the push rod to move. The push rod drives the sliding bracket to move. The sliding bracket drives the sliding cross column and the moving cross block to move inward. The moving cross block drives the semi-circular sealing cover to move and fit tightly against the outer surface of the puncture needle. Then control the positioning cross column to drive the moving cross frame to pull to the left. The moving cross frame drives the right-angle auxiliary frame and the semi-circular sealing plate to insert into the interior of the semi-circular sealing cover for auxiliary sealing operation. Then, the positioning rod is inserted into the interior of the positioning cross column through the moving cross block for positioning.

[0021] Step 8: Then open the solenoid valve. High-pressure gas enters the puncture needle through the inflation hood for inflation. The pressure change inside the sealed cylinder is monitored in real time by the alarm pressure gauge to determine whether the sealing performance of the puncture needle is qualified. If the pressure is abnormal, the alarm pressure gauge will issue an alarm signal, stop the detection and troubleshoot the puncture needle.

[0022] Step 9: After the test is completed, turn off the high-pressure air pump and solenoid valve, start the electric push rod to separate the semi-circular sealing cover and semi-circular sealing plate from the puncture guide, and at the same time start the drive motor to move the squeeze spring column and arc clamping plate outward to release the puncture needle and take out the puncture needle after the test is completed.

[0023] Compared with the prior art, the present invention provides a puncture and insertion device and a detection method, which have the following beneficial effects:

[0024] The puncture needle insertion device and method utilize a high-pressure air pump to drive a telescopic cylinder and a movable upright plate to push the puncture needle into the simulated tissue for puncture force testing. This facilitates better testing of the puncture needle's performance, resulting in more accurate and reliable test results. It also promotes more efficient puncture needle testing and improves the convenience of puncture needle testing.

[0025] The puncture needle insertion device and method use a clamping and fixing device to fix the puncture needle cannula, and a telescopic cylinder to push the puncture needle into the puncture needle cannula. Then, the puncture needle is pulled out of the puncture needle cannula to test the insertion and withdrawal force. This allows for a more comprehensive inspection of the puncture needle, reduces manual operation, improves detection efficiency and accuracy, and reduces the impact of human factors on the detection results.

[0026] This puncture needle detection device and method, through the cooperation of a compression sealing device and an auxiliary sealing device, and the double sealing of a semi-circular sealing cover and a semi-circular sealing plate, can effectively seal the puncture needle. Combined with an alarm pressure gauge to monitor pressure changes in real time, it ensures accurate and effective detection of the puncture needle's sealing performance, timely detection of sealing problems, and guarantees the safety of the puncture needle in actual use, while improving the convenience and efficiency of the detection process.
