Hand wheel rotating mechanism and electronic endoscope bending part fatigue testing device

Abstract

The invention discloses a hand wheel rotating mechanism and an electronic endoscope bending part fatigue testing device. The hand wheel rotating mechanism comprises an upper and lower hand wheel motor module and a left and right hand wheel motor module, the upper and lower hand wheel motor module comprises an upper and lower hand wheel fixing piece, and the upper and lower hand wheel fixing piece is connected with a first driving mechanism through a first transmission assembly; the left and right hand wheel motor module comprises a left and right hand wheel fixing piece, and the left and right hand wheel fixing piece is connected with a second driving mechanism through a second transmission assembly; according to the invention, the bending fatigue test can be automatically carried out by the machine, the labor intensity of manual operation of the bending fatigue test of the operation part of the electronic endoscope is reduced, the production test efficiency is improved, and the accuracy of the bending angle in the fatigue test process is ensured through the automatic test system. Therefore, the tensile force of the steel wire in the endoscope body after testing is in a stable state, and the requirements of high-precision control of the operation part of the electronic endoscope and positioning of the bending angle of the bending part are met.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an electronic handwheel rotating mechanism and a fatigue testing device for the bending part of an endoscope. Background technique [0002] Such as Figure 1 to Figure 2 As shown, the existing electronic endoscope generally includes an electronic endoscope operating part 601 and a head end bending part 603. The electronic endoscope operating part 601 is provided with up and down handwheels 604, left and right handwheels 605, up and down handwheels 604 and The left and right handwheels 605 pull the head-end bending portion 603 through the inner steel wire to control the direction of the head-end bending portion 603 . In specific use, the doctor needs to turn the upper and lower handwheels 604 or the left and right handwheels 605, and then control the bending part 603 of the head end to bend upwards, downwards, leftwards, and rightwards respectively, so as to realize multi-angle ob...

Problems solved by technology

Among them, the bending fatigue test in step 2) adopts manual testing, that is, after step 1) is completed, the periodic bending fatigue test is performed by manually turning the handwheel, and the rotation direction of a test cycle includes up, down, left, right, up Left, right, down, left, right and other six directions, the whole test process is labor-intensive and the test efficiency is low, and the manual test cannot guarantee that the bending part of the head end can be tested according to the specified bending angle in each test cycle
