[0002] With the development of CMOS (Complementary Metal Oxide Semiconductor) image sensors, electronic endoscopes that integrate the entire camera module into the front end of the cannula are becoming more and more common. For many endoscopic application scenarios, such as cystoscopy and hysteroscopy, since the cannula is inserted into a relatively narrow cavity in the human body, such as the urethra or cervical canal, the maximum outer diameter of the cannula needs to be as small as possible to reduce insertion resistance and alleviate the patient's pain; however, in actual applications, in order to facilitate operation, the inner diameter of the instrument channel needs to be as large as possible, resulting in the outer diameter of the cannula and the inner diameter of the instrument channel being difficult to meet the use requirements at the same time. Summary of the invention

[0003] The object of the present invention is to provide an intubation device and an endoscope, wherein the intubation device reduces the outer diameter of the intubation body without affecting the use effect.

[0004] To achieve this object, the present invention adopts the following technical solutions:

The second end of the operating rod is connected to the module assembly, and the center line of the operating rod is eccentrically arranged with the center line of the module assembly. The module assembly is moved so that part of the module assembly is located in the avoidance gap to reduce the shielding area of ​​the module assembly on the proximal end of the storage channel.

[0009] As a further technical solution, an insertion channel and a first working channel are provided in the storage channel, the proximal end of the insertion channel is arranged corresponding to the avoidance gap, the first end of the operating rod can be movably inserted in the insertion channel, and the first working channel is used for inserting the operating tool.

[0011] The auxiliary part is provided with a guide surface, and the guide surface is inclined in the direction close to the avoidance gap from the proximal end of the cannula body to the distal end of the cannula body. The operating rod is connected to the auxiliary part and can move along the guide surface so that part of the module assembly is located in the avoidance gap.

[0012] As a further technical solution, the auxiliary part is configured as a plastic part, including a connecting part, an inclined part and a supporting part, the inclined part is movably arranged between the connecting part and the supporting part, the connecting part is arranged at the proximal end of the cannula body, the inclined part is configured as the guide surface, and when the operating rod is movably inserted into the placement channel, the module assembly is located at the supporting part.

[0013] As a further technical solution, a guide limit groove is provided in the middle of the inclined portion, and the guide limit groove extends along the direction from the supporting portion to the connecting portion, and the operating rod can be limitably connected to the guide limit groove.

[0014] As a further technical solution, a second working channel is provided in the storage channel, the second working channel is used to insert an operating tool, the auxiliary part is connected to the inner wall of the storage channel, and the first end of the operating rod can be movably inserted between the outer wall of the second working channel and the inner wall of the storage channel.

[0015] As a further technical solution, the module assembly includes an operating member and a lighting member, the lighting member is arranged on the operating member, and the operating rod is eccentrically connected to the operating member.

[0016] As a further technical solution, a limiting portion is provided on the inner wall of the end seat, and the proximal end of the cannula body is limitedly connected to the limiting portion.

[0017] As a further technical solution, along the axial direction of the cannula body, the cross-sectional area of ​​the module assembly is smaller than the cross-sectional area of ​​the end seat.

[0018] An endoscope comprises an operating device and an intubation device, wherein the intubation device can be movably arranged on the operating device.

[0019] Compared with the prior art, the intubation device and endoscope provided by the present invention have the following technical advantages:

[0020] Since the operating rod is connected to the module assembly, and the operating rod and the module assembly are eccentrically arranged, when the operating rod is inserted behind the storage channel; the module assembly is moved so that part of the module assembly is located in the avoidance gap, the shielding area of ​​the module assembly on the proximal end of the storage channel is reduced, and the proximal outlet of the storage channel is partially exposed.

The intubation device, since the avoidance gap is provided, and the operating rod and the module assembly are eccentrically arranged, the first state and the second state can be switched by moving the module assembly; and in the whole process, the module assembly does not occupy the internal space of the storage channel, so that the outer diameter of the intubation body can be reduced as much as possible without affecting the use effect of the operating tool to meet clinical needs. At the same time, since the module assembly is movable, part of the module assembly can be located in the avoidance gap, so that under the premise of using the same outer diameter cannula body, a larger size module assembly can be assembled to further improve the practical performance of the cannula device.

[0038] Combination Figures 1 to 9 As shown, the intubation device provided in this embodiment reduces the outer diameter of the intubation body 100 without affecting the use effect. Specifically, the intubation device includes the intubation body 100, the end seat 200 and the operation module 300: the intubation body 100 is provided with a storage channel that penetrates the intubation body 100 along its axial direction; the end seat 200 is provided at the proximal end of the intubation body 100 corresponding to the storage channel, and the end seat 200 is provided with an avoidance gap 210; the operation module 300 includes an operating rod 310 and a module assembly 320, the first end of the operating rod 310 can be movably inserted in the proximal end of the storage channel and extended to the distal end of the storage channel, the second end of the operating rod 310 is connected to the module assembly 320, and the center line of the operating rod 310 is eccentrically arranged with the center line of the module assembly 320, and the module assembly 320 is rotated so that part of the module assembly 320 is located in the avoidance gap 210, so as to reduce the shielding area of ​​the module assembly 320 on the proximal end of the storage channel.

[0039] Since the operating rod 310 is connected to the module assembly 320, and the operating rod 310 and the module assembly 320 are eccentrically arranged, when the operating rod 310 is inserted behind the storage channel; the module assembly 320 is moved so that part of the module assembly 320 is located in the avoidance gap 210, the shielding area of ​​the module assembly 320 on the proximal end of the storage channel is reduced, and the proximal outlet of the storage channel is partially exposed. At this time, the entire intubation device is in the first state, and then the operating tool can be placed into the storage channel from the exposed outlet for subsequent operations. When the module assembly 320 is moved so that the entire module assembly 320 is located in the end seat 200, the module assembly 320 blocks the proximal outlet of the storage channel, and the entire intubation device is in the second state, so as to complete the storage of the intubation device. Since the intubation device is provided with an avoidance notch 210, and the operating rod 310 and the module assembly 320 are eccentrically arranged, the first state and the second state can be switched by moving the module assembly 320; and during the whole process, the module assembly 320 does not occupy the internal space of the storage channel, so that the outer diameter of the intubation body 100 can be reduced as much as possible without affecting the use effect of the operating tool to meet clinical needs. At the same time, since the module assembly 320 is moved, part of the module assembly 320 can be located in the avoidance notch 210, so that a larger module assembly 320 can be assembled under the premise of using the intubation body 100 of the same outer diameter, so as to further improve the practical performance of the intubation device.

[0040] Furthermore, the placement channel is provided with an intubation channel 111 and a first working channel 112, the proximal end of the intubation channel 111 is provided corresponding to the avoidance notch 210, the first end of the operating rod 310 can be movably inserted in the intubation channel 111, and the first working channel 112 is used to insert an operating tool. The intubation channel 111 and the first working channel 112 are relatively independently provided, the operating rod 310 is movably inserted in the intubation channel 111, and the operating tool is provided in the first working channel 112, so that the operating tool and the operating rod 310 are prevented from interfering with each other during operation. At the same time, since the module assembly 320 does not occupy the internal space of the intubation channel 111, the outer diameter of the intubation body 100 can be reduced as much as possible without affecting the inner diameter of the first working channel 112, so as to meet the clinical demand that the inner diameter of the first working channel 112 is as large as possible and the outer diameter of the intubation body 100 is as small as possible.

[0041] In some other embodiments, the avoidance notch 210 can be arranged in any direction. In this embodiment, for the convenience of description, the avoidance notch 210 is uniformly arranged upward, and the cannula channel 111 is arranged above the first working channel 112. Figure 4As shown, after the module assembly 320 rotates 180°, part of the module assembly 320 is located in the avoidance gap 210, and the module assembly 320 no longer blocks the first working channel 112. At this time, the proximal outlet of the first working channel 112 is exposed, so that the operating tool can be placed in the first working channel 112 for subsequent operations. Figure 5 As shown, in the second state, the operating rod 310 is located in the cannula channel 111 , and the module assembly 320 blocks the proximal outlet of the first working channel 112 .

[0042] In another embodiment, the operating module 300 also includes an auxiliary part 330, which is arranged at the proximal end of the cannula body 100 corresponding to the avoidance gap 210; the auxiliary part 330 is provided with a guide surface, and the guide surface is inclined in the direction from the proximal end of the cannula body 100 to the distal end of the cannula body 100 toward the direction close to the avoidance gap 210. The operating rod 310 is connected to the auxiliary part 330 and can move along the guide surface so that part of the module assembly 320 is located in the avoidance gap 210.

[0043] The module assembly 320 and the operating rod 310 can be arranged concentrically or eccentrically. Specifically, when the module assembly 320 and the operating rod 310 are arranged concentrically and the intubation device needs to be switched to the first state, the module assembly 320 is moved so that both the module assembly 320 and the operating rod 310 move along the guide surface in a direction close to the avoidance gap 210, so that part of the module assembly 320 is located in the avoidance gap 210, so that the proximal outlet portion of the placement channel is exposed. When the module assembly 320 and the operating rod 310 are arranged eccentrically and the intubation device needs to be switched to the first state, the module assembly 320 is rotated 180° and the module assembly 320 is moved at the same time so that both the module assembly 320 and the operating rod 310 move along the guide surface in a direction close to the avoidance gap 210, so that part of the module assembly 320 is located in the avoidance gap 210, so that the proximal outlet portion of the placement channel is exposed.

[0044] Furthermore, a second working channel 113 is provided in the storage channel, and the second working channel 113 is used to insert an operating tool. The auxiliary part 330 is connected to the inner wall of the storage channel, and the first end of the operating rod 310 can be movably inserted between the outer wall of the second working channel 113 and the inner wall of the storage channel. During operation, interference between the operating tool and the operating rod 310 can be avoided. Since both the module assembly 320 and the operating rod 310 move along the guide surface, and the auxiliary component 330 provided with the guide surface is arranged corresponding to the avoidance gap 210, the movement stability of the module assembly 320 and the operating rod 310 can be ensured in the process of moving the module assembly 320 to switch the state of the intubation device; therefore, it is not necessary to specially set a channel for limiting the relative position of the operating rod 310, that is, some structures in the storage channel can be reduced. Therefore, the entire intubation device, without affecting the inner diameter size of the second working channel 113 and ensuring the use effect of the operating module 300, can reduce the outer diameter of the intubation body 100 as much as possible to meet the clinical needs of making the second working channel 113 as large as possible and the outer diameter of the intubation body 100 as small as possible.

[0045] Preferably, the auxiliary member 330 is configured as a plastic member, including a connecting portion 331, an inclined portion 332 and a supporting portion 333, the inclined portion 332 is movably disposed between the connecting portion 331 and the supporting portion 333, the connecting portion 331 is disposed at the proximal end of the cannula body 100, the inclined portion 332 is configured as a guide surface, and when the operating rod 310 is movably inserted into the storage channel, the module assembly 320 is located at the supporting portion 333. When it is necessary to switch from the second state to the first state, the auxiliary member 330 is pulled in a direction away from the proximal end of the cannula body 100, and the auxiliary member 330 is stretched under the action of the pulling force, as shown in FIG. Figure 8 As shown, at this time, the distance between the support portion 333 and the avoidance gap 210 is reduced, part of the module assembly 320 is located in the avoidance gap 210, and the proximal outlet of the second working channel 113 is exposed, so that the operating tool can be placed in the second working channel 113 for subsequent operations. When the auxiliary member 330 is pushed in the direction close to the proximal end of the cannula body 100, the auxiliary member 330 is folded, as shown in FIG. Fig. 9 As shown, at this time, the distance between the support portion 333 and the avoidance gap 210 increases, and the module assembly 320 moves in the direction away from the avoidance gap 210 along with the support portion 333, and the module assembly 320 blocks the proximal outlet of the second working channel 113, and the entire intubation device switches to the second state. In addition, since the auxiliary member 330 is set as a plastic member, the convenience of the auxiliary member 330 when being stretched or folded can be improved, and at the same time, it is ensured that after the auxiliary member 330 is stretched or folded, it is always in the current state without applying external force, thereby ensuring the stability of the intubation device when it is in the current state.

[0046] Furthermore, a guide limit groove 3321 is provided in the middle of the inclined portion 332, and the guide limit groove 3321 extends from the support portion 333 to the connection portion 331, and the operating rod 310 can be limitedly connected to the guide limit groove 3321. The operating rod 310 is always inserted in the guide limit groove 3321, and when the auxiliary part 330 is stretched or folded, it is ensured that the operating rod 310 and the module assembly 320 always move with the movement of the auxiliary part 330, so as to ensure consistency when the position changes; after the auxiliary part 330 is stretched or folded, the guide limit groove 3321 limits the relative position of the operating rod 310 and the module assembly 320, so as to further improve the stability of the intubation device when it is in the current state. Figure 7 As shown, in this embodiment, the guide limit groove 3321 passes through the connecting portion 331 along the direction from the supporting portion 333 to the connecting portion 331; in this way, the slot area of ​​the guide limit groove 3321 can be increased, thereby improving the convenience of the operating rod 310 passing through the guide limit groove 3321 and being inserted between the outer wall of the second working channel 113 and the inner wall of the storage channel.

[0047] In an optional technical solution of this embodiment, the module assembly 320 includes an operating member 321 and a lighting member 322 , the lighting member 322 is disposed on the operating member 321 , and the operating rod 310 is eccentrically connected to the operating member 321 .

[0048] Specifically, when the proximal outlet of the storage channel is not provided with the auxiliary part 330, the operating rod 310 is eccentrically connected to the operating part 321; when the proximal outlet of the storage channel is provided with the auxiliary part 330, the operating rod 310 can be eccentrically connected to the operating part 321, or can be arranged concentrically with the operating part 321. The lighting part 322 provides illumination for the operating part 321 to enhance the convenience of manipulating the operating rod 310 through the operating part 321; the operating rod 310 is arranged as a braided tube with good torsion resistance and good bending performance to ensure the clinical use effect of the operating rod 310. In addition, in order to ensure the overall flexibility and self-strength of the intubation device, in this embodiment, the intubation body 100 adopts a snake bone tube.

[0049] Preferably, the inner wall of the end seat 200 is provided with a limiting portion 220, and the proximal end of the cannula body 100 is limitedly connected to the limiting portion 220. Figure 2 As shown, in this embodiment, the limiting portion 220 is configured as a limiting step protruding from the inner wall of the end seat, and the limiting step extends along the circumference of the end seat 200; after the end seat 200 is connected to the proximal end of the cannula body 100, the proximal end of the cannula body 100 abuts against the limiting step to further enhance the connection stability and connection accuracy between the end seat 200 and the cannula body 100.

[0050] Preferably, along the axial direction of the cannula body 100, the cross-sectional area of ​​the module assembly 320 is smaller than the cross-sectional area of ​​the end seat 200. When the cannula device is in the first state, it is convenient to place part of the module assembly 320 in the avoidance gap 210; when the cannula device is in the second state, the module assembly 320 is completely located in the end seat 200, so as to reduce the storage volume of the cannula device.

[0051] The endoscope comprises an operating device and an intubation device, wherein the intubation device can be movably arranged on the operating device.

[0052] The operating device is provided with a mounting channel, the intubation device is movably arranged in the mounting channel, and the end seat 200 and the module assembly 320 are exposed at the proximal end of the mounting channel, and the distal end of the intubation body 100 extends out of the distal end of the mounting channel. By adopting the module assembly 320, the intubation device does not occupy the storage channel, so that the endoscope meets the clinical requirements of the inner diameter of the working channel as large as possible and the outer diameter of the intubation body 100 as small as possible.

[0053] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention.
