Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a tooling for fixing the tension of an endoscope traction rope. Background Technology
[0002] Medical endoscopes typically include an operating section (also called a handle) and an insertion section. The active bending section at the distal end of the insertion section is connected to a traction wheel rotatably mounted on the operating section via a traction rope. The operator controls the rotation of the traction wheel by controlling the rotation angle of a lever, thereby pulling the traction rope to control the degree of bending of the active bending section.
[0003] The traction rope and traction wheel constitute the traction mechanism. The traction rope needs to be kept at a preset tension level in order to accurately control the bending degree of the active bending section. Since the traction rope structure is flexible and not fixed, its direction and position are uncontrollable. If the tension of the traction rope deviates from the preset tension level during the production and assembly process, there will be empty stroke, which will result in the inability to accurately control the bending angle of the active bending section. Utility Model Content
[0004] This utility model discloses an endoscope traction rope tension-fixing fixture, which solves the problem that due to the flexible structure of the traction rope and the uncontrollable direction and position, it may deviate from the preset tension during the production and assembly process, resulting in empty strokes and thus making it impossible to accurately control the bending angle of the active bending section. It effectively ensures that the traction rope always remains vertical and flat during the production and assembly process, and ensures that the tension on the traction rope is constant and at the expected tension value.
[0005] To achieve the above objectives, the technical solution of this utility model is specifically implemented as follows:

[0029] To address the problem that during the production and assembly process of traction ropes, due to their flexible structure and uncontrollable direction and position, the assembled traction rope may deviate from the preset tension, resulting in idle stroke and thus making it impossible to accurately control the bending angle of the active bending section, this utility model discloses a traction rope tension fixed length tool.
[0030] Specifically, see Figures 1-5 The system includes a top cover 1 and a base 2. A plurality of connecting posts 11 are provided on the end face of the top cover 1 facing the base 2. The top cover 1 is connected to the base 2 via the connecting posts 11. Preferably, positioning pins are provided inside the connecting posts, and the top cover 1 is connected to the base 2 via the positioning pins. Positioning posts 12 are also provided on the end face of the top cover 1 facing the base 2. (See [reference]) Figure 1 See also Figures 2-4 One end of the base 2 is provided with a first support member 21 for placing the rotating sleeve 3 and the catheter on the endoscope. A boss 22 is provided on the side of the base 2 opposite to the first support member 21. Preferably, the boss 22 is a circular boss. The positioning post 12 and the boss 22 cooperate to position the traction wheel 4. A first wire passage groove 23, a second wire passage groove 24 and a second support member 25 are arranged in sequence between the boss 22 and the first support member 21, and the first wire passage groove 23 is close to the boss 22. A first support plate 26 and a second support plate 27 are fixedly connected to one end of the base 2 near the boss 22. The first support plate 26 and the second support plate 27 are symmetrically fixed on both sides of the base 2 along the width direction.

The first through groove 255 and the second through groove 256 are connected. A first extension block 257 is formed on the first support column 251, and a second extension block 258 is formed on the second support column 252. The first extension block 257 and the second extension block 258 clamp the end of the traction rope protection tube bracket 5.
[0036] As one embodiment of this utility model, see Figure 5 The tooling also includes a clamp 6, one end of which is connected to a traction rope 7, and the other end is connected to a weight 8 corresponding to a preset tension value, which can keep the tension constant and at the desired tension value.
[0037] For the specific usage process of the traction rope tension fixed length fixture disclosed in this utility model, please refer to [link / reference]. Figure 5 :
[0038] Place the traction rope (not yet lengthened) and the endoscope catheter body into the corresponding positions on the base. Place the rotating sleeve 3 on the first support 21 of the fixture. Place the end of the traction rope protection tube bracket 5 between the first extension block 257 and the second extension block 258 to clamp the traction rope protection tube bracket 5. Place the traction wheel 4 on the boss 22. The top cover 1 is connected to the base 2. The positioning post 12 and the boss 22 cooperate to position the traction wheel 4. At this time, the traction rope 7 passes through the second wire groove 24, the first wire groove 23, and the through hole on the traction wheel 4. Then reverse the fixture, that is, the top cover... 1. Place the top cover 1 on the table, that is, place the end face of the top cover 1 away from the base 2 on the table. Pass the traction rope 7 through the hole of the traction wheel 4 through the rotating shaft 28. The end of the traction rope 7 is connected to one end of the clamp 6. The other end of the clamp 6 is connected to a weight 8 corresponding to the preset tension value. This ensures that the traction rope 7 is always kept straight and that the tension on the traction rope 7 is constant and the desired tension value is achieved. The operator applies glue to the hole of the traction wheel 4 through the groove 29 designed on the base 2 to fix the traction wheel 4 and the traction rope 7 together.
[0039] This invention uses tooling to ensure the vertical and flat state of the traction rope during the production and assembly process, ensuring that the tension on the traction rope remains constant and is the expected tension value, thereby ensuring that the assembled traction rope is at the preset tension level.
