Description

Technical Field

[0001] This utility model relates to the field of length-fixing devices, specifically to a length-fixing device for an endoscope catheter traction wire. Background Technology

[0002] An endoscopic catheter guide wire length control device is used to control the length of the endoscopic catheter guide wire. During endoscopic examinations or treatments, medical personnel need to use the guide wire to control the position and direction of the endoscope in order to accurately observe or manipulate the patient's internal organs or tissues. The length control device ensures that the length of the guide wire remains within a fixed range, avoiding difficulties or inconvenience caused by it being too long or too short.

[0003] The current length-setting device suffers from inaccuracies in length setting due to the uneven curling of the traction wire, making it difficult to tighten and straighten it. Therefore, improvements are needed. Utility Model Content

The guide block 86 is fixedly connected to the connecting frame 83. A first spring 87 is provided inside the pressure rod 84. One end of the first spring 87 is fixedly connected to the guide block 86, and the other end of the first spring 87 is fixedly connected to the pressure rod 84. By designing the first spring 87, the force of the first spring 87 can act on the guide block 86. By designing the marking mechanism 8, it is convenient to mark a fixed length position.

[0022] Please see Figure 1 , Figure 4The tensioning mechanism 9 includes a connecting rod 91. The connecting rod 91 is fixedly connected to the left end of the connecting block 6. The connecting rod 91 is slidably connected to the fixed seat 1. A groove 92 is provided on the back of the connecting rod 91. A retaining ball 93 is movably sleeved inside the groove 92. There are multiple grooves 92, which are evenly distributed inside the connecting rod 91. By designing multiple grooves 92, the retaining ball 93 can be inserted into the grooves 92 at different positions. The retaining ball 93 is movably connected to the fixed seat 1. A support block 94 is movably sleeved on the outside of the retaining ball 93. The support block 94 is slidably connected to the fixed seat 1. A fixing rod 95 is slidably sleeved inside the support block 94. The fixing rod 95 is fixedly connected to the fixed seat 1. A second spring 96 is provided on the outside of the fixing rod 95. One end of the second spring 96 is fixedly connected to the support block 94, and the other end of the second spring 96 is fixedly connected to the fixed seat 1.

[0023] The specific implementation process of this utility model is as follows: In use, first place the traction wire inside the fixed seat 1, then rotate the screw 4 so that the screw 4 makes a threaded movement. The screw 4 will drive the positioning block 5 to move down, so that the positioning block 5 presses the traction wire. Then, tie the other end of the traction wire and put it on the outside of the pull rod 7. Then pull the pull rod 7 horizontally. The pull rod 7 drives the connecting block 6 and the connecting rod 91 to move. The connecting rod 91 slides relative to the fixed seat 1. At the same time, the arc surface of the groove 92 inside the connecting rod 91 will squeeze and push the locking ball 93 to move. The locking ball 93 will... The support block 94 moves and slides along the fixed rod 95, squeezing the second spring 96. As the connecting rod 91 slides inside the fixed seat 1, the elastic action of the second spring 96 will give the support block 94 an outward push, which can push the support block 94 to reset. At this time, the locking ball 93 will roll into the groove 92 in another position, which can adjust and fix the relative position of the connecting rod 91 and the fixed seat 1. Then, the traction wire can be stretched and tightened by the pull rod 7, which can prevent the bending and wrinkling of the traction wire from affecting the fixed length measurement effect.

[0024] When it is necessary to mark the traction wire, first push the connecting frame 83 to move. The connecting frame 83 drives the slider 82 to slide along the slide groove 81. When the indentation block 85 is moved to the fixed length position, press down the pressure rod 84. The pressure rod 84 slides along the guide block 86 and squeezes the first spring 87. At the same time, the pressure rod 84 will drive the indentation block 85 to move down. Then, the fixed length position can be marked by indenting the traction wire, which is convenient for subsequent fixed length use. Moreover, the relative position of the indentation block 85 and the fixed seat 1 can be adjusted arbitrarily, which is convenient to use.
