Embodiment 1

[0027] See image 3 and Figure 4 , the spring tube holder of the endoscope operating part includes at least one spring tube fixing device 1, and each spring tube fixing device 1 includes a fixed guide seat 1A, a first connecting mechanism 2A and a second connecting mechanism 3A for connecting the spring Tube 3 and wire rope 4.

[0028] The fixed guide seat 1A is the main part of the spring tube fixing device 1, and generally adopts a structure with a relatively regular shape, such as a polygonal prism structure such as a square prism, a hexagonal prism, and an octagonal prism. A first through hole 4A is provided on the fixed guide seat 1A, the size of the inner diameter of the first through hole 4A matches the outer diameter of the spring tube 3, and can be slightly larger for insertion and welding of the spring tube 3, so that The spring tube 3 is fixedly connected with the spring tube fixing device 1, and the connection is firm and not easy to fall off during use.

[002...

Embodiment 2

[0039] See Figure 5 , In this embodiment, the spring tube fixing device includes a fixing guide seat 1B, a first connecting mechanism 2B and a second connecting mechanism 3B.

[0040] In this embodiment, the fixed guide seat 1B adopts a six-prism structure. The first connection mechanism 2B is a bolt hole provided on the bottom surface of the fixed guide seat 1B, and is connected with the fixed plate by bolts. The second connection mechanism 3B is similar to Embodiment 1. The second connection mechanism 3B is provided on the opposite side of the first connection mechanism 2B, that is, on the top surface of the fixed guide seat 1B, and also includes a boss and a counterbore. One-to-one correspondence of the counterbore holes, another spring tube fixing device is placed upside down on the top of the spring tube fixing device, so that their bosses and counterbores can be plugged in correspondence with each other, so that the two fixed guide seats 1B pass through the bosses and ...

Embodiment 3

[0042] See Figure 6 , In this embodiment, the spring tube fixing device includes a fixing guide seat 1C, a first connecting mechanism 2C and a second connecting mechanism 3C.

[0043] In this embodiment, the fixed guide seat 1C adopts a cuboid structure similar to that of the first embodiment, and the first connection mechanism 2C is a bolt hole provided on the bottom surface of the fixed guide seat 1C, which is connected to the fixed plate by bolts. A second connecting mechanism 3C is provided on adjacent and opposite sides of the first connecting mechanism 2C.

[0044] Wherein the second connecting mechanism 3C arranged on the opposite side of the first connecting mechanism 2C includes a boss and a counterbore, the boss corresponds to the counterbore one by one, another spring tube fixing device is placed upside down on the spring tube fixing device At the top, their bosses and counterbores can be plugged into each other correspondingly, so that the two fixed guide seats 1...

Abstract

The invention relates to a bourdon tube fixing structure for an endoscope operation part, which comprises at least one bourdon tube fixing device. The bourdon tube fixing device comprises a fixing guide seat, a first connecting mechanism and a second connecting mechanism; the fixing guide seat is provided with a first through hole for inserting a bourdon tube; the inner diameter of the first through hole is matched with the outer diameter of the bourdon tube; the first connecting mechanism is arranged on the fixing guide seat and used for being in detachable connection with a fixed plate; and the second connecting mechanism is arranged on the fixing guide seat and used for being in detachable matched connection with second connecting mechanisms of other bourdon tube fixing devices. According to the bourdon tube fixing structure for the endoscope operation part, a guide cylinder is omitted, and the bourdon tube is directly welded to the fixing guide seat, so that firm connection between the bourdon tube and the fixing guide seat is ensured, and the bourdon tube is difficult fall off in the using process; and meanwhile, two bourdon tube fixing structures are rapidly connected through the second connecting mechanism, so that the assembling steps are simplified, and the assembling efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to a spring tube fixer for an endoscope operating part and an installation method thereof. Background technique [0002] In the process of using endoscope for diagnosis and treatment, it is necessary to operate the U / D and R / L knobs to control the direction and angle of the bending part, so that the insertion tube enters the human mouth, throat, esophagus, stomach, and duodenum Smoother when waiting for parts. In the transmission structure where the knob controls the bending part, whether the wire rope moves smoothly or not directly affects the movement of the bending part, thereby affecting the entire diagnosis and treatment process, so the guiding role of the wire rope is very important. The spring tube covers the steel wire rope to protect the steel wire rope, so the fixed direction of the spring tube determines the direction of the steel wire rope. The traditional met...
