[0003] However, the rigidity of existing endoscope wiring harnesses is mostly fixed, making it difficult to adjust the rigidity according to the actual operation of the endoscope equipment and the environment. This results in insufficient structural flexibility and reduces the reliability of the endoscope equipment. Summary of the Invention

[0034] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this is not to limit the scope of the invention to this.

[0035] like Figures 1 to 12 As shown in this embodiment, an endoscope harness with built-in rigid adjustment includes a harness insulation layer 10, a thermosetting interlayer 20, and a heating element 30. The thermosetting interlayer 20 is coaxially disposed within the harness insulation layer 10. The thermosetting interlayer 20 may be made of shape memory polymers (polyurethane, epoxy resin), thermotropic liquid crystal polymers, thermoplastic elastomers (styrene-based, polyolefin, polyester, etc.) or nanocomposite materials (such as nano-clay, carbon nanotubes, nano-silica, etc.). Two heating elements 30 are disposed opposite each other on the inner wall of the thermosetting interlayer 20. The heating element 30 is preferably made of a metal material with uniform resistivity, such as a nickel-chromium alloy.

[0036] The thermosetting interlayer 20 is provided with a first adjustment component, a second adjustment component, and a bellows 60 connecting the first adjustment component and the second adjustment component; the first adjustment component, the second adjustment component, and the bellows 60 constitute a rigid adjustment section.

[0037] like Figure 2 , Figure 6 , Figures 8 to 10As shown, the first adjustment assembly includes a first adjustment seat 41, a first piston 42, a first elastic element 43, a first support block 44, and two first electrodes 45. The first adjustment seat 41 has a first air chamber 411. The first piston 42 is movably disposed within the first air chamber 411. The first elastic element 43 connects the first adjustment seat 41 and the first piston 42. The first support block 44 is movably disposed through the first adjustment seat 41 and is drively connected to the first piston 42. The two first electrodes 45 are disposed opposite each other on the first adjustment seat 41 and are electrically connected. The two first electrodes 45 are slidably sleeved on the two heating elements 30. The first electrodes 45 are in sliding electrical contact with the heating elements 30. The first electrodes 45 are made of a metal material with good conductivity and wear resistance. Preferably, the shape of the first electrodes 45 is adapted to the shape of the heating elements 30 to ensure that the first electrodes 45 and the heating elements 30 maintain good conductivity during the movement of the first electrodes 45. The first adjustment assembly also includes an electrically controlled locking assembly electrically connected to the two first electrodes 45. The electrically controlled locking assembly is used to lock the piston in an unlockable manner.

[0038] like Figure 3 , Figure 7 , Figure 8 , Figure 11 and Figure 12 As shown, the second adjustment assembly includes a second adjustment seat 51, a second piston 52, a second elastic element 53, a second support block 54, and two second electrodes 55. The second adjustment seat 51 has a second air chamber 511 that communicates with the first air chamber 411. The second piston 52 is movably disposed within the second air chamber 511. The second elastic element 53 is connected between the second adjustment seat 51 and the second piston 52. The stiffness of the second elastic element 53 is less than the stiffness of the first elastic element 43. The second support block 54 is movably disposed through the second adjustment seat 51 and is connected to the second piston 52. The two second electrodes 55 are disposed opposite each other on the second adjustment seat 51 and are electrically connected. The two second electrodes 55 are slidably sleeved on the two heating elements 30. The second electrodes 55 are in sliding electrical contact with the heating elements 30. The second electrodes 55 are made of a metal material with good conductivity and wear resistance. Preferably, the shape of the second electrode 55 is adapted to the shape of the heating element 30 to ensure that the second electrode 55 and the heating element 30 maintain good conductivity during the movement of the second electrode 55. The second adjusting seat 51 is also provided with two conductive rings 56 that are electrically connected to the two second electrodes 55 in a one-to-one correspondence. The first elastic element 43 is a first spring; the second elastic element 53 is a second spring.

[0039] like Figure 1 , Figure 5 and Figure 8As shown, a wire core 70 extends through the thermosetting interlayer 20 along its axis; the wire core 70 movably passes through the first adjustment assembly and the second adjustment assembly; the outer peripheral wall of the wire core 70 is provided with two conductive layers that are electrically coupled to the two conductive rings 56 in a one-to-one correspondence. In actual use, the conductive layers are respectively connected to the positive and negative terminals of an external power source.

[0040] To facilitate the explanation of this invention, this embodiment takes the center line of the wire harness as an example and divides the wire harness into upper and lower halves for explanation; initially, the rigid adjustment section is placed in a position symmetrical about the center line of the wire harness.

[0041] Specifically, if a rigid adjustment section is required to be located in the lower half of the wire harness, gas is first introduced into the bellows 60 to increase the air pressure inside the bellows 60 and extend it to both sides, thereby driving the first adjustment component and the second adjustment component to move synchronously along the axial direction of the wire core 70. When the bellows 60 is stretched to a certain length, gas with a pressure of P1 is introduced into the first air chamber 411 and the second air chamber 511. Since the stiffness of the second spring is less than that of the first spring, the second piston 52 slides against the elastic force of the second spring under the action of air pressure and pushes the second support block 54 to extend, so that the second support block 54 is tightly pressed against the inner wall of the thermosetting interlayer 20, thereby completing the locking of the second adjustment component.

[0042] Then, a certain amount of gas is extracted from the bellows 60, causing it to shorten. Since the position of the second adjusting component is fixed, the bellows 60 moves the first adjusting component closer to the second adjusting component until the first adjusting component moves to the appropriate position. Then, gas with a pressure of P2 is introduced into the first air chamber 411 and the second air chamber 511 again, where P2 is greater than P1. At this time, the first piston 42 slides against the elastic force of the first spring under the action of air pressure and pushes the first support block 44 to extend, so that the first support block 44 is tightly pressed against the inner wall of the thermosetting interlayer 20, thus completing the locking of the first adjusting component. Since P2 is greater than P1, the second piston 52 keeps the second support block 54 in the extended state under the action of air pressure. The two conductive layers are connected to an external power source. The rings 56 are electrically connected one-to-one, and the two conductive rings 56 are electrically connected one-to-one with the two second electrodes 55, thereby forming an electrical circuit between the two conductive layers, the two conductive rings 56, the two second electrodes 55, the two heating elements 30 and the two first electrodes 45. The current of the electrical circuit is controlled to be I1. At this time, the electronic locking component is energized to lock and fix the first piston 42, so that the first piston 42 is kept in the current position, that is, the first support block 44 is kept in the extended state, thereby making the first adjustment component completely locked. At the same time, the electrical circuit causes the heating element 30 between the first electrode 45 and the second electrode 55 to be energized and generate heat, so that the thermosetting interlayer 20 corresponding to the heating element 30 is heated and hardened, thereby realizing the rigid adjustment of the corresponding part of the endoscope wire harness.

[0043] If the rigid adjustment section needs to continue moving downwards, the current in the energizing circuit is reduced from I1 to I2. At this time, the electronically controlled locking assembly still locks the first piston 42, fixing the position of the first adjustment assembly. Then, the air pressure in the first air chamber 411 and the second air chamber 511 is reduced to below P1. At this time, the second spring pushes the second piston 52 to reset, and the second support block 54 retracts, freeing the second adjustment assembly. Then, gas is introduced into the bellows 60, causing the bellows 60 to move the second adjustment assembly downwards. After the second adjustment assembly moves into position, gas at a pressure of P1 is introduced into the first air chamber 411 and the second air chamber 511, causing the second support block 54 to extend, and the second adjustment assembly... The position is locked, and then the two conductive layers are disconnected from the external power supply. After the power is cut off by the electronic locking component, the locking of the first piston 42 is released. At this time, the first adjusting component is in a free state. Then, a certain amount of gas in the bellows 60 is extracted to shorten the bellows 60. Since the position of the second adjusting component is fixed, the bellows 60 drives the first adjusting component to move closer to the second adjusting component until the first adjusting component moves to the appropriate position. Then, gas with a pressure of P2 is introduced into the first air chamber 411 and the second air chamber 511 again to fix the position of the first adjusting component. Then, the power circuit is connected and the current is I1, so that the corresponding part of the thermosetting interlayer 20 is heated and hardened, realizing the downward movement of the rigid adjusting section.

[0044] If a rigid adjustment section is required to be located in the upper half of the wire harness, gas is introduced into the bellows 60 to extend it until the first adjustment component moves to a suitable position. Then, gas at a pressure of P2 is introduced into the first air chamber 411 and the second air chamber 511. At this time, the first support block 44 and the second support block 54 extend under the action of the first piston 42 and the second piston 52, respectively, thus fixing the positions of the first and second adjustment components. Then, the power circuit is connected with a current of I2 to energize the electronic locking component, locking the position of the first piston 42. Finally, the first air chamber 411 is... When the air pressure in the second air chamber 511 drops below P2, the second adjustment component is in a free state. Then, a certain amount of gas is extracted from the bellows 60, causing the bellows 60 to shorten. Since the position of the first adjustment component is fixed, the bellows 60 drives the second adjustment component to move closer to the first adjustment component until the second adjustment component moves to the appropriate position. Then, gas at a pressure of P1 is introduced into the first air chamber 411 and the second air chamber 511 again, fixing the position of the second adjustment component. Next, the current in the energizing circuit is adjusted to I1, thereby achieving rigid adjustment of the corresponding part of the endoscope wiring harness. Figure 5 As shown;

[0045] If the rigid adjustment section needs to continue moving upward, the power circuit is de-energized, the electronic locking assembly releases the lock on the first piston 42, and simultaneously, gas at pressure P1 is introduced into the first air chamber 411 and the second air chamber 511. At this time, the first adjustment assembly is in a free state, while the position of the second adjustment assembly is fixed. Then, gas is introduced into the bellows 60, causing the bellows 60 to move the first adjustment assembly upward to a suitable position. Then, gas at pressure P2 is introduced into the first air chamber 411 and the second air chamber 511, fixing the position of the first adjustment assembly. At this time, the power circuit can be connected, with a current of I2, and the electronic locking assembly locks the first piston 42. This keeps the position of the first adjusting component fixed. Then, the air pressure in the first air chamber 411 and the second air chamber 511 is reduced to below P2, so that the second adjusting component is in a free state. Then, a certain amount of gas is extracted from the bellows 60 to shorten the bellows 60. Since the position of the first adjusting component is fixed, the bellows 60 drives the second adjusting component to move closer to the first adjusting component until the second adjusting component moves to the appropriate position. Then, gas with a pressure of P1 is introduced into the first air chamber 411 and the second air chamber 511 again to fix the position of the second adjusting component. Then, the current of the energized circuit is adjusted to I1, thereby realizing the upward movement of the rigid adjusting section.

[0046] This embodiment, by setting a corrugated tube 60, a first adjustment component, and a second adjustment component within the thermosetting interlayer 20, utilizes the stiffness difference between the first and second springs, along with an electrically controlled locking component, to flexibly control the position and length of the corrugated tube 60 within the thermosetting interlayer 20. Furthermore, by utilizing the locking conditions of the first and second adjustment components under different air pressure values, flexible adjustment and reliable locking of the wire harness rigidity are achieved, improving the maneuverability of the wire harness and adapting it to different medical scenarios. This helps prevent damage to the internal wire core 70 due to excessive bending or stretching, thereby improving the reliability and lifespan of the endoscopic equipment.

[0047] like Figures 1 to 3 As shown, in some embodiments of the endoscope harness with built-in rigid adjustment, the first air chamber 411 and the second air chamber 511 are connected by a spiral air tube 80; the spiral air tube 80 is wound around the outer periphery of the bellows 60. This utilizes the extensibility of the spiral air tube 80 to accommodate changes in the distance between the first and second adjustment components, thereby ensuring that the first air chamber 411 and the second air chamber 511 remain in a connected state at all times.

[0048] like Figure 9 and Figure 11As shown, in some embodiments of the endoscope harness with built-in rigid adjustment, the first adjustment component further includes a first driving block 47 disposed on the first piston 42; the first driving block 47 is convexly connected to the first support block 44; the second adjustment component further includes a second driving block 57 disposed on the second piston 52; the second driving block 57 is convexly connected to the second support block 54. Thus, when the first piston 42 moves under air pressure, the first piston 42 drives the first driving block 47 to move, and the first driving block 47 drives the first support block 44 to move, thereby fixing the position of the first adjustment component; similarly, when the second piston 52 moves under air pressure, the second piston 52 drives the second driving block 57 to move, and the second driving block 57 drives the second support block 54 to move, thereby fixing the position of the second adjustment component.

[0049] like Figure 9 and Figure 11 As shown, in some embodiments of the endoscope harness with built-in rigid adjustment, the first drive block 47 and the second drive block 57 are both provided with a first inclined surface; the first support block 44 and the second support block 54 are both provided with a second inclined surface that slides in contact with the first inclined surface. This wedge-shaped fit between the first and second inclined surfaces allows the first drive block 47 to drive the first support block 44 to extend until it abuts against the inner wall of the thermosetting interlayer 20, thereby fixing the position of the first adjustment component. Similarly, the second drive block 57, through the fit between the first and second inclined surfaces, drives the second support block 54 to extend until it abuts against the inner wall of the thermosetting interlayer 20, thereby fixing the position of the second adjustment component.

[0050] like Figure 9 and Figure 11 As shown, in some embodiments of the endoscope harness with built-in rigid adjustment, two first support blocks 44 are disposed opposite to each other on the first adjustment seat 41; two first drive blocks 47 are disposed opposite to the first piston 42; two second support blocks 54 are disposed opposite to each other on the second adjustment seat 51; and two second drive blocks 57 are disposed opposite to the second piston 52. This embodiment, by providing two first support blocks 44 and two second support blocks 54, makes the positions of the first adjustment assembly and the second adjustment assembly more reliably and securely fixed.

[0051] like Figure 9 and Figure 11As shown, in some embodiments of the endoscope harness with built-in rigid adjustment, a first reset elastic member 48 is connected between the first support block 44 and the first adjustment seat 41; a second reset elastic member 58 is connected between the second support block 54 and the second adjustment seat 51; the first reset elastic member 48 is a first reset spring; and the second reset elastic member 58 is a second reset spring. Thus, when the first spring pushes the first piston 42 to reset, the first reset spring pushes the first support block 44 to retract and reset, so that the first adjustment assembly is in a free state; similarly, when the second spring pushes the second piston 52 to reset, the second reset spring pushes the second support block 54 to retract and reset, so that the second adjustment assembly is in a free state.

[0052] like Figure 10 As shown, in some embodiments of the endoscope harness with built-in rigid adjustment, the electrically controlled locking assembly includes a permanent magnet pin 461, a tension spring 462, and an electromagnet 463. The first piston 42 has a receiving hole; the permanent magnet pin 461 is slidably disposed in the receiving hole; the tension spring 462 is disposed between the hole wall of the receiving hole and the permanent magnet pin 461, so that the permanent magnet pin 461 is received in the receiving hole; the electromagnet 463 is disposed on the first adjusting seat 41; the electromagnet 463 is electrically connected to two first electrodes 45; the first adjusting seat 41 has a locking hole 412; when the electromagnet 463 is energized, the electromagnet 463 generates a magnetic attraction force on the permanent magnet pin 461, so that the permanent magnet pin 461 can overcome the action of the tension spring 462, extend out of the receiving hole, and insert into the locking hole 412. Specifically, when the air pressure in the first air chamber 411 and the second air chamber 511 is P2, the first piston 42 slides against the elastic force of the first spring, pushing out the first support block 44. At this time, the permanent magnet pin 461 corresponds to the position of the locking hole 412. If the power circuit is connected, the two first electrodes 45 energize the electromagnet 463, and the electromagnet 463 generates a magnetic attraction force on the permanent magnet pin 461, causing the permanent magnet pin 461 to extend towards the locking hole 412 against the action of the tension spring 462 until the permanent magnet pin 461 is inserted into the lock. The first piston 42 is locked within the stop hole 412, thereby keeping the first support pin in the extended state and fixing the position of the first adjusting component. This facilitates the position adjustment of the entire rigid adjusting section. When the energizing circuit is disconnected, the electromagnet 463 is de-energized and does not generate magnetic attraction on the permanent magnet pin 461. At this time, the tension spring 462 drives the permanent magnet pin 461 to move out of the locking hole 412, thereby unlocking the first piston 42 so that the position of the first adjusting component can be moved.

[0053] like Figure 1 , Figure 4 and Figure 5As shown, in some embodiments of the endoscope harness with built-in rigid adjustment, the end of the harness insulation layer 10 is provided with a pneumatic component; the pneumatic component includes a valve body 91 and a valve core 92, as well as a first telescopic air tube 93 and a second telescopic air tube 94 arranged coaxially; the first telescopic air tube 93 is located inside the second telescopic air tube 94; the first telescopic air tube 93 is connected to the bellows 60; the second telescopic air tube 94 is connected to the first air chamber 411;

[0054] The valve body 91 is provided with an air chamber 911; the valve core 92 is rotatably disposed in the air chamber 911; the valve core 92 is provided with an inlet valve 95 and an exhaust valve 96; one end of the first telescopic air pipe 93 and one end of the second telescopic air pipe 94 are both connected to the valve body 91; the other end of the first telescopic air pipe 93 is fixedly inserted through the first adjusting seat 41 and communicates with the bellows 60; the other end of the second telescopic air pipe 94 is fixedly inserted through the first adjusting seat 41 and communicates with the first air chamber 411; the valve body 91 extends with an air nozzle 912 that communicates with the air chamber 911.

[0055] Specifically, when it is necessary to extend the bellows 60, the valve core 92 is rotated so that the air inlet valve 95 corresponds to the position of the first telescopic air pipe 93. At this time, air is pumped into the air chamber 911 through the air nozzle 912, the air inlet valve 95 is opened, and the gas enters the first telescopic air pipe 93. After passing through the first telescopic air pipe 93, the gas enters the bellows 60, thereby extending the bellows 60. When it is necessary to shorten the bellows 60, the valve core 92 is rotated so that the exhaust valve 96 corresponds to the position of the first telescopic air pipe 93. Then, the air chamber 911 is evacuated, so that the exhaust valve 96 is opened. The gas in the bellows 60 enters the air chamber 911 through the first telescopic air pipe 93 and is then discharged, thereby reducing the air pressure in the bellows 60 and shortening the bellows 60.

[0056] When the position of the second adjusting component needs to be fixed, the air inlet valve 95 is aligned with the position of the second telescopic air pipe 94. At this time, air is pumped into the air chamber 911 through the air nozzle 912, the air inlet valve 95 is opened, and the gas enters the second telescopic air pipe 94. After passing through the second telescopic air pipe 94, the gas enters the first air chamber 411, and some of the gas enters the second air chamber 511 through the spiral air pipe 80. This increases the air pressure in the first air chamber 411 and the second air chamber 511 to P1, so that the second support block 54 extends. When the second adjusting component needs to be restored to its free state, the valve core 92 is rotated so that the position of the exhaust valve 96 is aligned with the position of the second telescopic air pipe 94. Then, the air chamber 911 is evacuated, so that the exhaust valve 96 is opened. The gas in the second air chamber 511 enters the first air chamber 411 through the spiral air pipe 80, and the gas in the first air chamber 411 is discharged into the air chamber 911 through the second telescopic air pipe 94. This reduces the air pressure in the second air chamber 511 to below P1, so that the second support block 54 retracts.

[0057] Similarly, when the position of the first adjusting component needs to be fixed, the air inlet valve 95 is aligned with the position of the second telescopic air pipe 94. At this time, air is pumped into the air chamber 911 through the air nozzle 912, the air inlet valve 95 is opened, and the gas enters the second telescopic air pipe 94. After passing through the second telescopic air pipe 94, the gas enters the first air chamber 411, and some of the gas enters the second air chamber 511 through the spiral air pipe 80, thereby increasing the air pressure in the first air chamber 411 and the second air chamber 511 to P2, so that the first support block 44 extends; when it is necessary to adjust the position of the first adjusting component, the air inlet valve 95 is aligned with the position of the second telescopic air pipe 94. At this time, air is pumped into the air chamber 911 through the air nozzle 912, the air inlet valve 95 is opened, and the gas enters the second telescopic air pipe 94. After passing through the second telescopic air pipe 94, the gas enters the first air chamber 411. Part of the gas enters the second air chamber 511 through the spiral air pipe 80, thereby increasing the air pressure in the first air chamber 411 and the second air chamber 511 to P2, so that the first support block 44 extends; when it is necessary to adjust the position of the first adjusting component, the air inlet valve 95 is aligned with the position of the second telescopic air pipe 94. At this time, the air inlet valve 95 is opened, and the gas enters the second telescopic air pipe 94. After passing through the second telescopic air pipe 94, the gas enters the first air chamber 411. At this time, the air inlet valve 95 is opened, and the gas enters the second telescopic air pipe 94. At this time, the air inlet valve 95 is opened, and the gas enters the second telescopic air pipe 94. At this time When the adjustment component returns to its free state, the valve core 92 is rotated so that the exhaust valve 96 corresponds to the position of the second telescopic air pipe 94. Then, the air chamber 911 is evacuated, so that the exhaust valve 96 is opened. The gas in the second air chamber 511 enters the first air chamber 411 through the spiral air pipe 80. The gas in the first air chamber 411 is discharged into the air chamber 911 through the second telescopic air pipe 94, thereby reducing the air pressure in the first air chamber 411 to below P2. When the electric locking component is not energized, the first support block 44 retracts.

[0058] like Figure 4 As shown, in some embodiments of the endoscope harness with built-in rigid adjustment, the valve core 92 has a rotating part 921 in the middle; the rotating part 921 extends out of the valve body 91 after passing through it. This embodiment, by providing the rotating part 921, facilitates the user's rotational operation to switch the positions of the intake valve 95 and the exhaust valve 96.

Therefore, any equivalent changes or modifications made to the structure, features and principles described in the claims of this patent application are included within the protection scope of this patent application.
