Embodiment 1

[0056] A specific embodiment of the present invention, such as Figure 1-Figure 4 As shown, a catheter bending measuring ruler is disclosed, including a disc ruler 1, a sliding ruler 2 and a slide rail rotation ruler, the disc ruler 1 is used to measure the angle between adjacent straight sections of the catheter, and the sliding ruler 2 is used to measure the straight line of the catheter The segment length, the slide rail rotation ruler is used to measure the plane rotation space angle of the adjacent curved section of the catheter, and the catheter bending measuring ruler can be used repeatedly.

[0057] During implementation, the catheter bending measuring ruler can be used repeatedly, and the data can be read by simply placing the measuring ruler on the catheter.

[0058] Compared with the prior art, the catheter bending measuring ruler provided in this embodiment, the disc ruler is used to measure the angle between the adjacent straight sections of the catheter, that is,...

Embodiment 2

[0103] Another specific embodiment of the present invention discloses a catheter bending measurement method, using the catheter bending measuring ruler of embodiment 1, the steps include:

[0104] S1: Assemble the catheter bending measuring ruler, and place each catheter bending measuring ruler on the catheter.

[0105] When assembling the catheter bending measuring ruler, the sliding ruler 2 is not installed, and the set screws are not tightened (the first set screw 313, the second set screw 314, the third set screw 413 and the fourth set screw in this embodiment Set screw 414), the first spacer 35 and the second spacer 45 are placed on the part where the straight line section of the conduit is tangent to the arc section.

[0106] It should be noted that when the catheter bending measuring ruler is placed on the catheter, no other means are required to fix it. The catheter bending measuring ruler is placed above the catheter, and the first slider 31 and the first sliding rail...

Abstract

The invention relates to a catheter bending measuring ruler and a measuring method, which belong to the technical field of catheter bending and forming, and solve the problems of low efficiency and high cost of the qualified inspection of the bending direction of the catheter in the prior art. The catheter bending measuring ruler of the present invention comprises a disc ruler (1), a sliding ruler (2) and a slide rail rotating ruler, the disc ruler (1) is used for measuring the angle between adjacent straight line segments of the catheter, and the sliding ruler (2) is used for Measure the length of the straight section of the catheter, and the slide rail rotation ruler is used to measure the plane rotation space angle of the adjacent curved section of the catheter. The catheter bending measuring ruler of the present invention can replace the current bending manufacturing inspection fixture, reduce the difficulty and workload of bending manufacturing, measurement, and revision procedures, reduce subjective judgments that lead to repeated trial and error in sampling work, and improve the accuracy of catheter bending measurement , which in turn speeds up the speed of catheter optimization and reduces production costs.

Description

technical field [0001] The invention relates to the technical field of catheter bending and forming, in particular to a catheter bending measuring ruler and a measuring method. Background technique [0002] At present, during the bending and forming process of the catheter, it is necessary to carry out the bending of the catheter according to the design. After the final assembly of the product, the sampling of the catheter is carried out when the conditions for the installation of the catheter are met. The bending manufacturing, final assembly, sampling adjustment, re-bending and re-adjustment of the catheter all require a lot of waiting and coordination time, and repeated manufacturing trial and error is required, and the cycle is long. [0003] Fixture trial adjustment of parts is a relatively common means to control the processing quality of parts, but the design of the inspection fixture for the bending direction of the conduit cannot include the detection functions such...
