[0001] This invention relates to the field of medical devices, and in particular to an endoscope with a snake-bone covered tube and its processing method. Background Technology

[0002] In the field of medical diagnostics, endoscopes play a crucial role. They can penetrate deep into the human body, providing doctors with a direct way to observe lesions and greatly improving the accuracy of disease diagnosis. One of the core components of an endoscope is the serpentine structure, and the serpentine sheath, as a closely related component, directly affects the overall performance of the endoscope.

[0003] In the existing technology, the sections of the snake-bone coated tube are connected to each other by connecting shafts. The connection stability and flexibility are not high. Moreover, the movement is usually controlled only by pull ropes, which is not automated enough and not adaptable to different situations. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] The problem to be solved by the present invention is to provide an endoscope snake-bone covered tube and its processing method, so as to overcome the shortcomings of insufficient flexibility and adaptability of the existing endoscope snake-bone covered tube.

[0006] (II) Technical Solution

[0007] To solve the aforementioned technical problem, a first aspect of the present invention provides an endoscope snake-bone covered tube, characterized in that it comprises:

One end of the outer snake-bone shell is arranged in a circular array around the axis of the outer snake-bone shell, with two rotating docking slots and two arc-shaped notches spaced apart. The other end of the outer snake-bone shell is provided with a rotating docking block.

[0009] The outer snake shell has multiple shells, and one end of each outer snake shell is connected to the other end of the next outer snake shell. When the endoscope snake shell covering tube rotates, the rotating docking block rotates in the rotating docking groove.

[0010] The outer snake-bone shell includes a first outer shell and a second outer shell. The first outer shell is provided with a sliding block, and the second outer shell is provided with a sliding groove. The inner wall of the first outer shell is provided with a first connecting block, and the inner wall of the second outer shell is provided with a second connecting block. The first outer shell and the second outer shell are slidably connected.

[0011] A multi-stage telescopic mechanism includes a motor, a fixed housing, a first screw, and multiple telescopic components. The fixed housing is connected to a first connecting block of the first outer serpentine housing. The fixed housing is connected to the motor. The output end of the motor is connected to the first screw. The first screw is connected to the telescopic components. The motor is used to control the extension / retraction of the height of each outer serpentine housing.

[0012] As described above, the endoscopic snake-bone covering tube may optionally include a telescopic housing, a fixing block, and a hollow screw in each of the telescopic components. The fixing block is disposed inside the telescopic housing, and the hollow screw is rotatably connected to the fixing block. The first screw is threadedly connected to the inner wall of the hollow screw.

[0013] As described above, the endoscopic snake-bone covering tube may optionally have one end of each telescopic housing fixed to the second connecting block of the previous outer snake-bone housing, and the other end of each telescopic housing fixed to the first connecting block of the subsequent outer snake-bone housing.

[0014] As described above, the endoscopic snake-bone covering tube may optionally have its outer surface slidably connected to the fixed housing, its bottom end slidably connected to the first screw, its outer surface slidably connected to the previous telescopic housing, and the inner wall of the hollow screw of the previous telescopic housing threadedly connected to the outer side of the previous telescopic housing. When the motor drives the first screw to rotate, the multiple telescopic housings extend / retract.

[0015] As described above, the endoscopic snake-bone covering tube may optionally have an outer diameter smaller than the inner diameter of the first telescopic housing and an outer diameter of the first hollow screw the same as the inner diameter of the second hollow screw.

[0016] As described above, the endoscopic snake-bone covering tube may optionally have two multi-stage telescopic mechanisms arranged opposite each other. When one of the multi-stage telescopic mechanisms is activated, the endoscopic snake-bone covering tube moves to the other side, and when the other multi-stage telescopic mechanism is activated, the endoscopic snake-bone covering tube moves to one side.

[0017] As described above, the endoscopic snake-bone sheath can optionally include a pressure sensor on each of the outer snake-bone shells.

[0018] As described above, the endoscopic snake-bone covering tube may optionally have a protective cover connected to the first outer snake-bone housing, and the motor connected to the protective cover.

[0019] As described above, the endoscopic snake-bone casing may optionally have an intermediate protective layer and an inner layer sequentially arranged on the inner wall of the outer snake-bone shell.

[0020] To achieve the aforementioned objective, a second aspect of the present invention provides a method for processing an endoscopic snake-bone covered tube as described in any one of the first aspects of the present invention, wherein the processing method is as follows:

[0021] S1: The outer snake-bone shell is produced by injection molding;

[0022] S2: Assemble each of the outer snake-bone shells and install the multi-stage telescopic mechanism;

[0023] S3: Install the intermediate protective layer and the inner layer.

[0024] (III) Beneficial Effects

[0025] The present invention provides an endoscope with a snake-bone-covered cannula and its processing method, which has the following beneficial effects:

[0026] (1) This invention manufactures multiple outer snake-bone shells by injection molding. The rotating docking block of the previous outer snake-bone shell is rotatably connected to the rotating docking groove of the next outer snake-bone shell. The outer snake-bone shell has a first connecting block and a second connecting block, and a multi-stage telescopic mechanism is connected to the first and second connecting blocks. Through the extension / retraction of the multi-stage telescopic mechanism located on both sides of the outer snake-bone shell, the multi-stage telescopic mechanism can drive the first screw to rotate via the rotation of a motor. The first screw drives the hollow screw to rotate, thereby extending / retracting the multi-stage telescopic mechanism. When the multi-stage telescopic mechanism on one side is activated, the endoscopic snake-bone covering tube moves to the other side; when the multi-stage telescopic mechanism on the other side is activated, the endoscopic snake-bone covering tube moves to one side. The rotational movement of this invention can be controlled. This design allows for flexible steering of the device via motor drive.

[0027] (2) By setting a first outer shell and a second outer shell on the outer snake shell, the first outer shell and the second outer shell can be extended / reduced under the drive of the multi-stage telescopic mechanism. This design can improve the compatibility of the device in different usage environments. Attached Figure Description

[0042] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0043] See Figures 1 to 7 This invention provides an endoscope snake-bone covered tube, characterized by comprising: multiple outer snake-bone shells 1, an intermediate protective layer 6, and an inner layer 7. The multiple outer snake-bone shells 1 are connected sequentially. The outer snake bones provide protection for this invention. The outer snake-bone shells 1 have high wear resistance and corrosion resistance, and are coated with a hydrophilic layer to reduce friction.

[0044] The material of the intermediate protective layer 6 can be, but is not limited to, woven fiber, which is flexible and improves the overall structural stability. The inner layer 7 is relatively smooth.

[0045] exist Figures 1 to 7 In an optional embodiment, the outer snake shell 1 is a hollow cylinder. One end of the outer snake shell 1 is arranged in a circular array around the axis of the outer snake shell 1, with two rotating docking grooves 11 and two arc-shaped notches 12 spaced apart. The other end of the outer snake shell 1 is provided with a rotating docking block 13.

[0046] It should be noted that there are multiple outer snake shells 1, and one end of each outer snake shell 1 is connected to the other end of the next outer snake shell 1. When the endoscope snake shell covering tube rotates, the rotating docking block 13 rotates in the rotating docking groove 11.

[0047] Furthermore, the outer snake-bone shell 1 includes a first outer shell 14 and a second outer shell 15. A sliding block 17 is provided in the first outer shell 14, and a sliding groove 16 is provided in the second outer shell 15. A first connecting block 18 is provided on the inner wall of the first outer shell 14, and a second connecting block 19 is provided on the inner wall of the second outer shell 15. The first outer shell 14 and the second outer shell 15 are slidably connected. By moving the first outer shell 14 within the second outer shell 15, the length of the outer snake-bone shell 1 can be freely adjusted.

[0048] Meanwhile, it should be noted that an auxiliary sliding rod is connected to the arc-shaped notch 12, and the interior of the second outer shell 15 has a slot. The auxiliary sliding rod is slidably connected to the slot. When multiple outer snake-bone shells 1 rotate, the auxiliary sliding rod can move within the slot, thereby playing the role of auxiliary connection.

[0049] exist Figures 1 to 7 In an optional embodiment, the multi-stage telescopic mechanism 2 includes a motor 21, a fixed housing 22, a first screw 23, and multiple telescopic components 3. The fixed housing 22 is connected to the first connecting block 18 of the first outer serpentine housing 1, the fixed housing 22 is connected to the motor 21, the output end of the motor 21 is connected to the first screw 23, the first screw 23 is connected to the telescopic components 3, and the motor 21 is used to control the extension / retraction of the height of each outer serpentine housing 1.

[0050] Furthermore, each telescopic component 3 includes a telescopic housing 31, a fixing block 32, and a hollow screw 33. The fixing block 32 is disposed inside the telescopic housing 31, the hollow screw 33 is rotatably connected to the fixing block 32, and the first screw 23 is threadedly connected to the inner wall of the hollow screw 33.

[0051] Furthermore, the outer surface of the first telescopic housing 31 is slidably connected to the fixed housing 22, the bottom end of the first telescopic housing 31 is slidably connected to the first screw 23, the outer surface of the second telescopic housing 31 is slidably connected to the first telescopic housing 31, and the inner wall of the hollow screw 33 of the second telescopic housing 31 is threadedly connected to the outer side of the first telescopic housing 31. When the motor 21 drives the first screw 23 to rotate, the multiple telescopic housings 31 extend / retract.

[0052] Furthermore, the outer diameter of the first telescopic housing 31 is smaller than the inner diameter of the second telescopic housing 31, and the outer diameter of the first hollow screw 33 is the same as the inner diameter of the second hollow screw 33.

[0053] Specifically, when the motor 21 rotates, the first screw 23 is driven to rotate. Since the first screw 23 is threadedly connected to the inner wall of the first hollow screw 33, the first hollow screw 33 rotates accordingly. The outer wall of the first hollow screw 33 is threadedly connected to the inner wall of the next hollow screw 33. Therefore, as the motor 21 rotates, the multi-stage telescopic mechanism 2 can extend / retract.

[0054] Furthermore, one end of each telescopic shell 31 is fixed to the second connecting block 19 of the preceding outer serpentine shell 1, and the other end of each telescopic shell 31 is fixed to the first connecting block 18 of the following outer serpentine shell 1. Therefore, the multi-stage telescopic mechanism 2 can drive the movement of the first outer shell 14 and the second outer shell 15.

[0055] It should be noted that there are two multi-stage telescopic mechanisms 2, which are arranged opposite each other. When one side of the multi-stage telescopic mechanism 2 is activated, the endoscope snake-like covering tube moves to the other side. When the other side of the multi-stage telescopic mechanism 2 is activated, the endoscope snake-like covering tube moves to one side.

[0056] Furthermore, each outer snake-bone shell 1 is equipped with a pressure sensor 4. The pressure sensor 4 is used to detect the pressure on the outer surface of the endoscope snake-bone covering tube.

[0057] Furthermore, the protective cover 5 is connected to the first outer snake-bone housing 1, and the motor 21 is connected to the protective cover 5.

[0058] Furthermore, the inner wall of the outer snake shell 1 is provided with an intermediate protective layer 6 and an inner layer 7 in sequence.

[0059] Furthermore,

[0060] Another aspect of the present invention provides a method for manufacturing an endoscopic snake-bone covered tube as described in any of the preceding claims, wherein the manufacturing method is as follows:

[0061] S1: The outer snake-bone shell 1 is produced by injection molding.

[0062] The outer snake-bone shell 1 is produced by injection molding.

[0063] S2: Assemble each outer snake-bone shell 1 and install a multi-stage telescopic mechanism 2;

[0064] Each produced outer snake-bone shell 1 is then installed. Specifically, the rotating docking block 13 of the previous outer snake-bone shell 1 is rotatably connected to the rotating docking groove 11 of the next outer snake-bone shell 1. The outer snake-bone shell 1 has a first connecting block 18 and a second connecting block 19. A multi-stage telescopic mechanism 2 is connected to the first connecting block 18 and the second connecting block 19, and the multi-stage telescopic mechanism 2 controls the extension / retraction of each outer snake-bone shell 1. The multi-stage telescopic mechanism 2 also controls the rotational movement of the shell.

[0065] S3: Install the intermediate protective layer 6 and the inner layer 7.

[0066] The intermediate protective layer 6 and the inner layer 7 are sequentially connected to the inner end of the outer snake shell 1.

[0067] The present invention relates to an endoscope snake-bone covered tube and its processing method, the specific steps of which are as follows:

[0068] Multiple outer snake-bone shells 1 are manufactured by injection molding. The rotating docking block 13 of the previous outer snake-bone shell 1 is rotatably connected to the rotating docking groove 11 of the next outer snake-bone shell 1. Each outer snake-bone shell 1 has a first connecting block 18 and a second connecting block 19. A multi-stage telescopic mechanism 2 is connected to the first connecting block 18 and the second connecting block 19. The extension / retraction of the multi-stage telescopic mechanism 2, located on both sides of the outer snake-bone shell 1, is achieved by the rotation of the motor 21, which drives the first screw 23 to rotate. The first screw 23 then drives the hollow screw 33 to rotate, thus extending / retracting the multi-stage telescopic mechanism 2. When one side of the multi-stage telescopic mechanism 2 is activated, the endoscopic snake-bone covering tube moves to the other side; when the other side of the multi-stage telescopic mechanism 2 is activated, the endoscopic snake-bone covering tube moves to one side. The rotational movement of this invention can be controlled. This design allows for flexible steering of the device via a motor 21 drive.

[0069] By providing a first outer shell 14 and a second outer shell 15 on the outer snake-bone shell 1, the first outer shell 14 and the second outer shell 15 can be extended / retracted under the drive of the multi-stage telescopic mechanism 2. This design can improve the compatibility of the device in different usage environments.
