[0002] Nowadays, more and more endoscopes are used to enter the human body for diagnosis and treatment. Since the digestive tract has the most cavities, the digestive tract endoscopes are the most common. Taking bile and pancreatic duct lesions as an example, in the face of complex conditions, in order to improve the diagnosis and treatment effect, oral choledochoscopy is usually used for further diagnosis and treatment; before using oral choledochoscopy, conventional ERCP (Endoscopic Retrograde Cholangiopancreatography, Chinese abbreviation: Endoscopic Retrograde Pancreatic Cholangiopancreatography) is usually performed first.

[0003] During ERCP, selective bile duct or pancreatic duct cannulation is the key to the success of ERCP. Conventional bile and pancreatic duct cannulation uses a guidewire-assisted pull-type incision knife intubation method.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Nowadays, more and more endoscopes are used to enter the human body for diagnosis and treatment. Since the digestive tract has the most cavities, the digestive tract endoscopes are the most common. Taking bile and pancreatic duct lesions as an example, in the face of complex conditions, oral choledochoscopy is usually used for further diagnosis and treatment to determine the treatment plan; before using oral choledochoscopy, a routine ERCP operation is usually performed first. In the ERCP operation, selective bile duct or pancreatic duct cannulation is the key to the success or failure of ERCP.

[0043] Conventional bile and pancreatic duct cannulation uses a guidewire-assisted pull-type incision knife intubation method, that is, through the duodenoscope instrument channel, a hydrophilic super-slippery guidewire is inserted into the duodenal papilla under the action of a lifting forceps. Under X-ray fluoroscopy, the guidewire is used to selectively explore the bile duct or pancreatic duct opening successfully, and then the incision knife is inserted into the papilla along the guidewire. After power is turned on, the papillary sphincter is cut; the guidewire is extended through the small hole at the front end of the incision knife, and the guidewire is inserted into the bile duct or pancreatic duct under X-ray fluoroscopy; when the guidewire is successfully inserted into the bile duct or pancreatic duct to a certain depth, the pull-type incision knife is slowly pushed along the guidewire until its front end reaches the predetermined position. Confirm whether the incision knife is accurately located in the bile duct or pancreatic duct under X-ray fluoroscopy; if the position is inaccurate, the position of the guidewire and incision knife needs to be readjusted.

[0044] The main invention of the present invention is to provide a visual intubation device 100 to solve the problem that the existing bile and pancreatic duct intubation cannot be performed under direct vision, resulting in intubation failure or even damage to organ tissue. The visual intubation device 100 will be mainly described below with reference to the accompanying drawings.

[0045] See also Figures 1 to 3 The visualization intubation device 100 includes an endoscope body 1 and an auxiliary mechanism 2; the endoscope body 1 includes a main handle 11 and an insertion tube 12, and the auxiliary mechanism 2 includes an auxiliary sheath 22. The auxiliary sheath 22 is arranged on the main handle 11, and is used to be inserted into the organ cavity 201. The auxiliary sheath 22 has an auxiliary end 221 away from the main handle 11, and a first curved section 22a close to the auxiliary end 221; the insertion tube 12 has a relative connecting end 121 and an inserting end 122, the connecting end 121 is arranged on the main handle 11, the inserting end 122 is movably inserted in the auxiliary sheath 22, and can be movably extended or retracted from the auxiliary end 221, the inserting end 122 is provided with an image acquisition element 3, and an instrument channel 123 for inserting consumable instruments is formed in the insertion tube 12, and the insertion tube 12 has a second curved section 12a close to the insertion end 122.

[0046] The visualization intubation device 100 further includes an adjustment mechanism 4 , which includes a first adjustment component 41 and a second adjustment component 42 . The first adjustment component 41 drives the first bending segment 22 a to bend, and the second adjustment component 42 drives the second bending segment 12 a to bend.

[0047] In the visualization intubation device 100 provided by the present invention, an auxiliary sheath 22 for inserting into an organ cavity 201 is provided on the main handle 11; the insertion tube 12 is movably inserted in the auxiliary sheath 22, and the insertion end 122 of the insertion tube 12 can be movably extended or retracted from the auxiliary end 221 of the auxiliary sheath 22. An image acquisition element 3 is provided on the insertion end 122; and an instrument channel 123 for inserting consumable instruments is formed in the insertion tube 12. The first adjustment component 41 drives the first curved section 22a connected to the auxiliary sheath 22, and the second adjustment component 42 drives the second curved section 12a connected to the insertion tube 12.

[0048] During the diagnosis and treatment process, please refer to Figure 4 and Figure 5 First, insert the auxiliary sheath 22 into the patient's organ cavity 201, push the insertion tube 12 so that its insertion end 122 extends from the auxiliary end 221, and at the same time, drive the second bending section 12a of the insertion tube 12 to bend through the second adjustment component 42, and use the image acquisition element 3 on the insertion end 122 to find the target affected area 202. In other words, the insertion tube 12 is equivalent to the insertion part of the oral choledochoscope in the prior art, and the auxiliary sheath 22 is set to replace the duodenoscope in the prior art to provide a stable insertion path for the insertion tube 12; at the same time, the first adjustment component 41 is set to drive the first bending section 22a to bend to adjust the bending angle of the head of the auxiliary sheath 22, which is equivalent to the duodenoscope lifting forceps in the prior art; in this way, the auxiliary sheath 22 is used to replace the duodenoscope in the prior art, which can greatly reduce the cost of the visualization intubation device 100.

[0049] As mentioned above, the auxiliary sheath tube 22 can replace the duodenoscope to provide a stable insertion path for the insertion tube 12, but the auxiliary sheath tube 22 does not have an image acquisition function. Therefore, in the embodiments of the present application, please refer to Figure 6, the image acquisition element 3 on the insertion end 122 of the insertion tube 12 is used to find the target affected part 202. Different from the side view observation of the duodenoscope in the prior art, the image acquisition element 3 on the insertion end 122 can be directly observed during the advancement of the insertion tube 12, which is more conducive to finding the target affected part; after the target affected part 202 is determined by the image acquisition element 3 on the insertion end 122, the insertion tube 12 is retracted so that the insertion end 122 is retracted from the auxiliary end 221; the auxiliary sheath 22 is pushed, and the first bending section 202 is driven by the first adjustment component 41 2a is bent so that the image acquisition element 3 of the insertion end 122 can face the target affected part 202; finally, the insertion tube 12 is pushed so that the insertion end 122 reaches the target affected part 202, thereby completing the visualized intubation operation; at the same time, the consumable instrument can be inserted from the instrument channel 123 and reach the target affected part 202 for treatment; in this way, when encountering tortuous or complex branched organ tissues, the insertion tube 12 can also accurately reach the target affected part 202 to achieve precise intubation, thereby reducing the risk of organ tissue damage caused by repeated intubation attempts.

[0050] In one embodiment, see Figure 1 A main channel (not shown in the figure) is formed in the main handle 11, and a first inlet 111 connected to the main channel is provided on the main handle 11; the connecting end 121 is provided on the main handle 11 and is connected to the main channel, so that the consumables device can be inserted into the device channel 123 from the first inlet 111 through the main channel.

[0051] In one embodiment, see Figure 1 The auxiliary mechanism 2 also includes an auxiliary handle 21, which is arranged on the main handle 11. An auxiliary channel (not shown in the figure) is formed in the auxiliary handle 21, and a second inlet 211 connected to the auxiliary channel is provided on the auxiliary handle 21; an auxiliary sheath 22 is arranged on the auxiliary handle 21 and is connected to the auxiliary channel; the insertion end 122 is movably inserted into the auxiliary sheath 22 from the second inlet 211 through the auxiliary channel.

[0052] As mentioned above, the visualization intubation device 100 includes an endoscope body 1 and an auxiliary mechanism 2, wherein an auxiliary handle 21 of the auxiliary mechanism 2 is disposed on the main handle 11 of the endoscope body 1. The present application does not impose any specific restrictions on the arrangement of the auxiliary handle 21 and the main handle 11.

[0053] The insertion tube 12 and the main handle 11 are arranged along the axial direction of the insertion tube 12; the auxiliary sheath 22 and the auxiliary handle 21 are arranged along the axial direction of the auxiliary sheath 22; the axial direction of the insertion tube 12 and the axial direction of the auxiliary sheath 22 are arranged in parallel, temporarily set to the first direction F1.

[0054] The main handle 11 has a first end surface in the second direction F2, and the auxiliary handle 21 is disposed on the first end surface; wherein the second direction F2 is disposed to intersect with the first direction F1.

[0055] The present invention does not impose any specific restrictions on the connection state of the auxiliary handle 21 and the main handle 11. The auxiliary handle 21 and the main handle 11 can be fixedly connected; the auxiliary handle 21 and the main handle 11 can also be detachably connected.

[0056] In one embodiment, the visualization intubation device 100 further includes a detachable connection structure 5, which includes a connecting portion and a matching portion that cooperate with each other, one of which is provided on the main handle 11, and the other is correspondingly provided on the auxiliary handle 21. Through the connecting portion and the matching portion, the auxiliary handle 21 and the main handle 11 are detachably connected, with a simple structure and easy disassembly and assembly.

[0057] The present invention does not impose any specific restrictions on the connection method between the auxiliary handle 21 and the main handle 11. The auxiliary handle 21 and the main handle 11 can be threadedly connected and fixed; the auxiliary handle 21 and the main handle 11 can be buckled and fixed; the auxiliary handle 21 and the main handle 11 can also be plugged and fixed.

[0058] Specifically, a male buckle is provided on the main handle 11; a female buckle is provided on the auxiliary handle 21; it is known that a male buckle is generally a component with a protrusion, a hook or a tenon; a female buckle is generally a component with a groove, a hole or a slot 51 for accommodating the male buckle. In other words, please refer to Figure 7 and Fig. 9 A slot 51 is provided on the auxiliary handle 21; a limit buckle 52 is provided on the main handle 11, and the limit buckle 52 is inserted into the slot 51; wherein, one of the connecting part and the matching part is set as the slot 51, and the other is set as the limit buckle 52.

[0059] In an exemplary embodiment, see Figure 7 and Fig. 9 The auxiliary handle 21 has a second end face facing the main handle 11; a boss is protrudingly provided on the second end face, and a slot 51 is provided on the side wall of the boss in the first direction F1; a limit buckle 52 is provided on the first end face of the main handle 11; during assembly, the first end face and the second end face are arranged opposite to each other, and the main handle 11 and the auxiliary handle 21 are pushed relative to each other along the first direction F1, so that the limit buckle 52 is inserted into the slot 51, thereby realizing the detachable connection between the main handle 11 and the auxiliary handle 21.

[0060] Also, see Figure 1When the auxiliary handle 21 is disposed on the main handle 11 , the second inlet 211 on the auxiliary handle 21 is higher than the insertion end 122 of the insertion tube 12 ; at this time, the insertion tube 12 needs to be rewound so that the insertion end 122 can be inserted from the second inlet 211 .

[0061] As described above, the first bending section 22a is driven to bend by setting the first adjustment component 41. In one embodiment, the first adjustment component 41 includes a first driving part 411 and a first transmission part. The first driving part 411 is arranged on the main handle 11 and can reciprocate relative to the main handle 11. The first transmission part is connected to the first driving part 411 and the first bending section 22a, so as to drive the first bending section 22a to bend toward different sides in its radial direction when the first driving part 411 reciprocates.

[0062] Specifically, see Figure 1 and Figure 2 The first transmission part includes two first traction ropes (not shown in the figure), two ends of the two first traction ropes are wound around the first driving part 411 in different directions, and the other two ends of the two first traction ropes are respectively connected to the first curved segment 22a, so that when the first driving part 411 reciprocates, the corresponding first traction ropes can be driven to pull the first curved segment 22a to drive the first curved segment 22a to bend toward different sides in its radial direction.

[0063] In an exemplary embodiment, the first driving part 411 is configured as a first rotating wheel; in actual use, two ends of the two first traction ropes are wound around the first rotating wheel in different directions, and the first rotating wheel is rotated forward, one of the first traction ropes is wound tight, and at this time, the first traction rope pulls the first curved segment 22a, so that the first curved segment 22a bends toward the corresponding side; the first rotating wheel is rotated reversely, the previously wound tight first traction rope is loosened, and the other first traction rope is wound tight, and at this time, the first traction rope pulls the first curved segment 22a, so that the first curved segment 22a bends toward the other side. Using a rotating wheel and a traction rope to drive the curved segment of the sheath to bend is a prior art and will not be described in detail here.

[0064] Furthermore, in accordance with the above “the auxiliary mechanism 2 further includes an auxiliary handle 21, which is disposed on the main handle 11”, the auxiliary sheath 22 is disposed on the auxiliary handle 21; the first driving part 411 is disposed on the auxiliary handle 21 and can reciprocate relative to the auxiliary handle 21. Specifically, the first rotating wheel is rotatably mounted on the auxiliary handle 21.

[0065] At the same time, the second bending section 12a is driven to bend by setting the second adjustment component 42. The second adjustment component 42 includes a second driving part 421 and a second transmission part. The second driving part 421 is arranged on the main handle 11 and can reciprocate relative to the main handle 11. The second transmission part is connected to the second driving part 421 and the second bending section 12a, so as to drive the second bending section 12a to bend toward different sides in its radial direction when the second driving part 421 reciprocates.

[0066] Specifically, see Figure 1 and Figure 2 The second transmission part includes two second traction ropes (not shown in the figure), two ends of the two second traction ropes are wound around the second driving part 421 in different directions, and the other two ends of the two second traction ropes are respectively connected to the second curved segment 12a, so that when the second driving part 421 reciprocates, the corresponding second traction ropes can be driven to pull the second curved segment 12a to drive the second curved segment 12a to bend toward different sides in its radial direction.

[0067] In an exemplary embodiment, the second driving unit 421 is configured as a second rotating wheel; in actual use, two ends of the two second traction ropes are wound around the second rotating wheel in different directions, and the second rotating wheel is rotated forward, one of the second traction ropes is tightened, and at this time, the second traction rope pulls the second curved segment 12a to make the second curved segment 12a bend toward the corresponding side; the second rotating wheel is rotated reversely, the previously tightened second traction rope is loosened, and the other second traction rope is tightened, and at this time, the second traction rope pulls the second curved segment 12a to make the second curved segment 12a bend toward the other side.

[0068] It can be understood that during the diagnosis and treatment process, the auxiliary sheath 22 is first inserted into the patient's organ cavity 201, and the insertion tube 12 is pushed so that its insertion end 122 extends from the auxiliary end 221. At the same time, the second bending section 12a of the insertion tube 12 is driven to bend through the second adjustment component 42, and the image acquisition element 3 on the insertion end 122 is used to find the target affected area 202; when encountering difficult nipples (such as long nipples, juxta-diverticular nipples), in order to accurately find the target affected area 202, the second bending section 12a needs to be able to bend in multiple directions.

[0069] The adjustment mechanism 4 comprises at least two sets of second adjustment components 42. The two sets of second adjustment components 42 enable the second bending section 12a to bend in four directions.

[0070] The present application does not specifically limit the arrangement of the second driving parts 421. In one embodiment, the movable planes of the two second driving parts 421 of the two sets of second adjustment components 42 can be arranged crosswise or in parallel.

[0071] In one embodiment, the movable planes of the two second driving parts 421 of the two groups of second adjustment components 42 are arranged in parallel, the two second traction ropes of each group of second adjustment components 42 form a first traction plane, and the two first traction planes formed by the two groups of second adjustment components 42 are arranged crosswise; in this way, the second bending section 12a can be bent in four directions by using four second traction ropes.

[0072] For example, two second rotating wheels are arranged on the main handle 11; the two second rotating wheels are stacked in the second direction F2, and the two second rotating wheels have the same rotation axis. Every two second traction ropes are wound around one second rotating wheel; the two second traction ropes on one second rotating wheel form a first traction plane, and the two second traction ropes on the other second rotating wheel form another first traction plane, and the two first traction planes are arranged crosswise, so that the second bending section 12a can be bent in four directions by using four second traction ropes.

[0073] It should be noted that the bending direction of the second bending section 12a may be completely different from the bending direction of the first bending section 22a. Among the multiple bending directions of the second bending section 12a, some bending directions may overlap with the first bending section 22a.

[0074] In one embodiment, two ends of the two first traction ropes of the first adjustment component 41 are wound around the first driving part 411 in different directions, and the other two ends of the two first traction ropes are respectively connected to the first bending section 22a, and the two first traction ropes form a second traction plane; one group of the first traction planes of the second adjustment components 42 are arranged parallel to the second traction plane; in this way, it can be achieved that the second bending section 12a has two bending directions that are the same as the first bending section 22a.

[0075] For example, two second rotating wheels are arranged on the main handle 11; the two second rotating wheels are stacked in the second direction F2, and the two second rotating wheels have the same rotation axis; a first rotating wheel is arranged on the auxiliary handle 21, and the first rotating wheel and the second rotating wheel have the same rotation axis. Two first traction ropes are respectively connected to the first rotating wheel and the first curved section 22a, and form a second traction plane; the two second traction ropes of each set of second adjustment components 42 form a first traction plane; the second traction plane is arranged parallel to one of the first traction planes, so that when the first rotating wheel and the second rotating wheel rotate, the second curved section 12a can have two bending directions that are the same as the first curved section 22a.

[0076] As mentioned above, the auxiliary sheath 22 is provided to replace the duodenoscope of the prior art. Since the auxiliary sheath 22 only provides a stable insertion path for the insertion tube 12, other functional elements need to be provided on the insertion tube 12 to ensure the functional integrity of the visualization intubation device 100. Based on actual diagnosis and treatment operations, the insertion tube 12 also needs to have flushing and lighting functions. In one embodiment, please refer to Figure 8 A liquid inlet channel and a lighting channel are also formed in the insertion tube 12; the visualization intubation device 100 also includes a nozzle 6 and a light-emitting element 7.
