Description

Technical Field

[0001] The present invention relates to the technical field of medical supplies, and in particular to a spring tube fixer of an endoscope operating part and a mounting method thereof. Background Art

[0002] During the process of diagnosis and treatment using an endoscope, 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 can enter the human body's mouth, throat, esophagus, stomach, duodenum and other parts more smoothly. In the transmission structure where the knob controls the bending part, the smoothness of the movement of the wire rope directly affects the movement of the bending part, thereby affecting the entire diagnosis and treatment process. Therefore, the guiding role of the wire rope is very important. The spring tube covers the wire rope to protect it, so the fixing direction of the spring tube determines the direction of the wire rope. The traditional method is to weld the guide tube and the spring tube, and then make an interference fit between the guide tube and the fixing seat, and the wire rope is covered in the spring tube. The fixing structure of the spring tube plays a guiding role for the wire rope, such as Figure 1 shown.

[0003] If this fixing method is used too many times, there is a risk that the guide tube will fall off from the opening groove of the fixing seat. To address this risk, the current method used is to use a card to limit the direction in which the guide tube is likely to fall off, such as Figure 2 Although this solution solves the risk of the guide tube falling off, the assembly method is relatively cumbersome, which wastes time and increases labor costs. Summary of the invention

[0004] In view of this, it is necessary to provide a spring tube fixer for an endoscope operating part and an installation method thereof, so as to solve the technical problems that the existing method for solving the problem of guide tube falling off is cumbersome to assemble, wastes time and increases labor costs.

[0005] The present invention provides a spring tube fixer of an endoscope operating part, which is arranged on a fixing plate of the endoscope operating part and comprises: at least one spring tube fixing device, which comprises a fixing guide seat, a first connecting mechanism and a second connecting mechanism, wherein a first through hole for inserting a spring tube is provided on the fixing guide seat, and the inner diameter of the first through hole matches the outer diameter of the spring tube, the first connecting mechanism is arranged on the fixing guide seat and is detachably connected to the fixing plate, and the second connecting mechanism is arranged on the fixing guide seat and is used for detachably cooperating with the second connecting mechanism of other spring tube fixing devices.

[0006] Furthermore, the spring tube fixing device also includes a protrusion integrally connected to the fixing guide seat, and a second through hole communicating with the first through hole is formed on the protrusion.

[0007] Furthermore, the first through hole and the second through hole have the same inner diameter and are coaxially arranged.

[0008] Furthermore, the first connecting mechanism, the second connecting mechanism and the protruding portion are arranged on different surfaces of the fixed guide seat.

[0009] Furthermore, the fixed guide seat is a prismatic structure, and the second connecting mechanism is arranged on the adjacent or opposite side of the first connecting mechanism, and is used to connect the adjacent or oppositely arranged spring tube fixing devices.

[0010] Furthermore, the second connecting mechanism is arranged on the adjacent and opposite sides of the first connecting mechanism, and is used to connect the adjacent and oppositely arranged spring tube fixing devices. The second connecting mechanism arranged on the adjacent or opposite sides of the first connecting mechanism can adopt the same or different settings.

[0011] Furthermore, the first connecting mechanism is a threaded hole, and the fixed guide seat is detachably fixed to the fixed plate by bolts.

[0012] Furthermore, the second connection mechanism includes a boss and a countersunk hole, and the boss and the countersunk hole correspond one to one, so that the two fixed guide seats are connected through the boss and the countersunk hole.

[0013] Furthermore, the second connecting mechanism includes a positioning pin and a pin hole, and both ends of the positioning pin are respectively inserted into the pins of the two spring tube fixing structures.

[0014] The present invention provides a method for installing a spring tube fixture of an endoscope operating part, and the method for installing the spring tube fixture of the endoscope operating part comprises the following steps: S1, connecting one end of a steel wire rope to a steel wire rope connector, and extending the other end thereof into the spring tube; S2, inserting the spring tube into a through hole and welding the spring tube to the fixed guide seat; S3, connecting the fixed guide seat to other fixed guide seats through the second connecting mechanism; S4, installing the fixed guide seat on the fixed plate through the first connecting mechanism.

[0015] Compared with the prior art, the spring tube fixing structure of the endoscope operating part eliminates the guide tube and matches the first through hole with the spring tube. The spring tube is directly welded to the fixed guide seat after passing through the first through hole, thereby ensuring that the spring tube and the fixed guide seat are firmly connected and not easy to fall off during use. At the same time, a second connecting mechanism is used to quickly connect the two spring tube fixing devices to each other, thereby simplifying the assembly steps and improving assembly efficiency.

[0025] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0026] Embodiment 1

[0027] See also Figure 3 and Figure 4 The spring tube fixture of the endoscope operating part includes at least one spring tube fixture 1, each spring tube fixture 1 includes a fixed guide seat 1A, a first connecting mechanism 2A and a second connecting mechanism 3A, which are used to connect the spring tube 3 and the wire rope 4.

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

[0029] A first connecting mechanism 2A is provided on the fixed guide seat 1A. The first connecting mechanism 2A is a connecting structure for connecting the fixed guide seat 1A to other components of the endoscope operating part. Usually, the endoscope operating part includes a fixed plate 2 for installing the spring tube fixing device 1, that is, the fixed guide seat 1A is connected to the fixed plate 2 or other structures through the first connecting mechanism 2A.

[0030] The fixed guide seat 1A is also provided with a second connection mechanism 3A, which is a structure for connecting two different fixed guide seats 1A to each other. Since the endoscope operating part usually includes a plurality of spring tube fixing devices 1, these spring tube fixing devices 1 are connected at least two by two, so that they can play a role of mutual support and fixation, making the structure of the entire endoscope operating part more stable.

[0031] So see Figure 7 The present invention provides an installation method for a spring tube fixing structure of an endoscope operating part, which is as follows: Step S1, connect one end of a steel wire rope 4 to a steel wire rope connector 5, and extend the other end thereof into a spring tube 3, to complete the installation; Step S2, insert the spring tube 3 into a first through hole 4A and weld it to a fixed guide seat 1A; Step S3, connect the fixed guide seat 1A to other fixed guide seats 1A through a second connecting mechanism 3A; Step S4, install the fixed guide seat 1A on a fixed plate 2 through a first connecting mechanism 2A.

[0032] Since the spring tube 3 is fixedly welded in the first through hole 4A, the steel wire 4 is inserted into the spring tube 3. In order to better control the steel wire 4, the guide distance between the steel wire 4 and the spring tube 3 can be increased, that is, the length of the first through hole 4A is extended. However, since the adjustable range of the size of the fixed guide seat 1A is limited, it is preferred that a protrusion 5A is integrally fixedly provided on the fixed guide seat 1A, and a second through hole communicating with the first through hole 4A is opened on the protrusion 5A, and the spring tube 3 passes through the first through hole 4A and the second through hole.

[0033] Here, the first through hole 4A and the second through hole play the same role, so it is obvious that it is most appropriate to arrange the first through hole 4A and the second through hole coaxially and to have the same inner diameters, so that the first through hole 4A and the second through hole actually form a through hole with the same inner diameters at all locations. This is convenient for machining and can be formed in one step, and the spring tube 3 can be well matched and connected with the through hole at all locations, without the possibility of loose welding or large shaking.

[0034] It is easy to know that since the protrusion 5A is used to connect the spring tube 3, the first connection mechanism 2A is used to connect the fixing plate 2, and the second connection mechanism 3A is used to connect the second connection mechanism 3A of another spring tube fixing device 1, the two spring tube fixing devices 1 are connected together. Therefore, in order to avoid mutual influence between these three components, it is preferred that the first connection mechanism 2A, the second connection mechanism 3A and the protrusion 5A are arranged on different surfaces of the fixed guide seat 1A, and point to different directions respectively.

[0035] Moreover, the spring tube fixing devices 1 can be connected to each other in pairs, or multiple spring tube fixing devices 1 can be connected together to form a whole. Therefore, preferably, the second connecting mechanism 3A can be arranged on the adjacent or opposite side of the first connecting mechanism 2A for connecting another adjacent or oppositely arranged spring tube fixing device 1. The second connecting mechanism 3A can also be arranged on the adjacent and opposite sides of the first connecting mechanism 2A for simultaneously connecting two other adjacent and oppositely arranged spring tube fixing devices 1.

[0036] Further preferably, when the second connecting mechanism 3A is simultaneously arranged on adjacent and opposite sides of the first connecting mechanism 2A, the second connecting mechanism 3A arranged on the adjacent side of the first connecting mechanism 2A may be the same as or different from the second connecting mechanism 3A arranged on the opposite side of the first connecting mechanism 2A.

[0037] As in the present embodiment, the fixed guide seat 1A adopts a rectangular parallelepiped structure, and the first connection mechanism 2A is two bolt holes arranged on the bottom surface of the fixed guide seat 1A, which are connected to the fixed plate 2 by bolts. A second connection mechanism 3A is arranged on the side opposite to the first connection mechanism 2A, that is, on the top surface of the fixed guide seat 1A. The second connection mechanism 3A in the present embodiment includes a boss and a countersunk hole, and the boss and the countersunk hole correspond one to one. Another spring tube fixing device 1 is inverted on top of the spring tube fixing device 1, and their bosses and countersunk holes can be plugged in correspondingly with each other, so that the two fixed guide seats 1A are connected together through the boss and the countersunk hole.

[0038] Embodiment 2

[0039] See also Figure 5In this embodiment, the spring tube fixing device includes a fixed 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 6-prism structure. The first connecting mechanism 2B is a bolt hole set on the bottom surface of the fixed guide seat 1B, which is connected to the fixed plate by bolts. The second connecting mechanism 3B is similar to the first embodiment. The second connecting mechanism 3B is set on the side opposite to the first connecting mechanism 2B, that is, on the top surface of the fixed guide seat 1B. It also includes a boss and a countersunk hole. The boss and the countersunk hole correspond one to one. Another spring tube fixing device is inverted on top of the spring tube fixing device so that their bosses and countersunk holes can be plugged in with each other, so that the two fixed guide seats 1B are connected together through the boss and the countersunk hole.

[0041] Embodiment 3

[0042] See also Figure 6 In this embodiment, the spring tube fixing device includes a fixed 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 rectangular parallelepiped structure similar to that of the first embodiment, and the first connecting 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. The second connecting mechanism 3C is provided on the adjacent and opposite sides of the first connecting mechanism 2C.

[0044] The second connecting mechanism 3C arranged on the side opposite to the first connecting mechanism 2C includes a boss and a countersunk hole, and the boss and the countersunk hole correspond one to one. Another spring tube fixing device is inverted on top of the spring tube fixing device, and their bosses and countersunk holes can be plugged into each other accordingly, so that the two fixed guide seats 1C are connected together through the boss and the countersunk hole.

[0045] The second connection mechanism 3C disposed on the side adjacent to the first connection mechanism 2C includes a positioning pin and a pin hole. The two spring tube fixtures are arranged side by side, and the two ends of the positioning pin are respectively inserted into the pin holes on the opposite sides of the two spring tube fixtures to complete the connection.

[0046] The implementation of the embodiments of the present invention has the following beneficial effects: the spring tube fixing structure of the endoscope operating part eliminates the guide tube and matches the first through hole with the spring tube. The spring tube is passed through the first through hole and is directly welded to the fixed guide seat, thereby ensuring that the spring tube and the fixed guide seat are firmly connected and are not easy to fall off during use; at the same time, a second connecting mechanism is used to quickly connect the two spring tube fixing devices to each other, thereby simplifying the assembly steps and improving assembly efficiency.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
