Embodiment
[0035] Now a medical curved needle made by the present invention is tested and compared with a common puncture needle on the market. The test process is as follows:
[0036] 1. The medical simulation mold is used to determine the location of the lesion that is not convenient for linear puncture. Two different puncture methods are used to perform 20 punctures, and the number of puncture deviations is calculated.
[0037] 2. Using a medical simulation mold to determine the location of the lesion that is not convenient for linear puncture, use two different puncture methods to perform 20 punctures, determine the puncture result, and calculate the accuracy of the puncture.
[0038] 3. The medical simulation mold is used to determine the location of the lesion that is not convenient for linear puncture. Two different puncture methods are used to perform ten punctures, and the total puncture time is recorded.
[0039] The test data are as follows:
[0040] Offset times / time Accuracy / % Co...
