Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an endoscope device. Background Technology

[0002] Today, more and more endoscopes are being used for diagnosis and treatment in the human body's cavities. Since the digestive tract has the most cavities, the types of digestive tract endoscopes are also the most numerous. Taking biliary and pancreatic duct diseases as an example, to improve diagnostic and treatment outcomes, transoral cholangioscopy is often used. Before using transoral cholangioscopy, a routine ERCP (Endoscopic Retrograde Cholangiopancreatography) is usually performed first.

[0003] In ERCP, selective bile duct or pancreatic duct cannulation is crucial to the success of the procedure. Conventional bile duct and pancreatic duct cannulation uses a guidewire-assisted pull-type scalpel cannulation method. During cannulation, the guidewire and scalpel can only be inserted into the papilla with the help of the duodenoscope lifting forceps, and can only be roughly aligned with the direction of the bile duct or pancreatic duct. Direct visualization can not be performed. When encountering difficult papillae (such as long papillae or diverticulum papillae), repeated attempts to insert the cannula may damage the papilla, bile duct or pancreatic duct, leading to serious complications. Utility Model Content

[0004] The main purpose of this invention is to propose an endoscopic device that aims to solve the problem that existing bile and pancreatic duct cannulation methods cannot be performed under direct vision, leading to cannulation failure or even tissue damage.

[0005] To achieve the above objectives, this utility model proposes an endoscope device, comprising:

[0006] The endoscope body includes a main handle and an insertion tube. The insertion tube is disposed on the main handle and has a first end away from the main handle and a first curved section near the first end. An instrument channel for inserting consumable instruments is formed inside the insertion tube, and an image acquisition element is disposed on the first end.

[0007] An auxiliary mechanism includes an auxiliary handle and a sheath, the auxiliary handle being disposed on the main handle, and the sheath having a second end remote from the auxiliary handle and a second curved section near the second end; and,

[0010] Preferably, a main channel is formed inside the main handle, and a first inlet communicating with the main channel is provided on the main handle;

[0011] The insertion tube is disposed on the main handle and communicates with the main channel, so that the consumable device can be inserted into the device channel from the first inlet via the main channel.

[0012] Preferably, an auxiliary channel is formed inside the auxiliary handle, and a second inlet communicating with the auxiliary channel is provided on the auxiliary handle;

[0013] The sheath is disposed on the auxiliary handle and communicates with the auxiliary channel;

[0014] The first end is movably inserted into the sheath via the second inlet and the auxiliary channel.

[0015] Preferably, the endoscope device further includes a detachable connection structure, which includes a connecting part and a mating part that cooperate with each other. One of the connecting part and the mating part is disposed on the main handle, and the other is disposed on the auxiliary handle.

[0016] Preferably, the auxiliary handle is provided with a slot; the main handle is provided with a limit buckle, which is inserted into the slot to fix the auxiliary handle and the main handle relative to each other.

[0017] The connecting part and the mating part are configured as either a slot or a limiting buckle.

[0018] Preferably, the insertion tube also has a liquid inlet channel and a lighting channel.

[0019] The endoscope device further includes a nozzle and a light-emitting element. The nozzle is disposed at the first end of the insertion tube and communicates with the liquid inlet channel so that the liquid in the liquid inlet channel can be ejected from the nozzle. The light-emitting element is disposed at the first end of the insertion tube and its optical fiber passes through the illumination channel.

[0020] Preferably, the first adjustment assembly includes a first rotating wheel and two first traction ropes. The first rotating wheel is rotatably mounted on the main handle. Two ends of the two first traction ropes are wound around the first rotating wheel in different directions. The other ends of the two first traction ropes are respectively connected to the first curved section, so that when the first rotating wheel rotates in different directions, the corresponding first traction rope can be driven to pull the first curved section to bend.

[0021] Preferably, the second adjustment assembly includes a second rotating wheel and two second traction ropes. The second rotating wheel is rotatably mounted on the auxiliary handle. One end of each of the two second traction ropes is wound around the second rotating wheel in different directions. The other ends of the two second traction ropes are respectively connected to the second curved section, so that when the second rotating wheel rotates in different directions, the corresponding second traction rope can be driven to pull the second curved section to bend.

[0022] Preferably, the adjustment mechanism includes at least two sets of the first adjustment components, and the two first traction ropes of each set of the first adjustment components form a first traction plane, and the two first traction planes formed by the two sets of the first adjustment components are arranged in a cross pattern.

An auxiliary handle of the auxiliary mechanism is disposed on the main handle of the endoscope body. An insertion tube is disposed on the main handle. A sheath for inserting into an organ cavity is disposed on the auxiliary handle. The insertion tube is movably inserted into the sheath, and the first end of the insertion tube can extend or retract from the second end of the sheath. During diagnosis and treatment, the sheath is first inserted into the patient's organ cavity, and the insertion tube is pushed so that its first end extends from the second end. The first curved section of the insertion tube is driven to bend by a first adjustment component, and the image acquisition element on the first end is used to locate the target lesion. The insertion tube is then withdrawn so that its first end retracts from the second end. The sheath is then pushed again, and the second curved section is driven to bend by a second adjustment component so that the image acquisition element at the first end can directly view the target lesion. The insertion tube is then pushed so that its first end reaches the target lesion, thereby completing the visualized intubation operation. Thus, even when encountering tortuous or complexly branched organ tissues, the insertion tube can accurately reach the target lesion, achieving precise intubation and reducing the risk of organ tissue damage caused by repeated intubation attempts.

[0043] Today, more and more endoscopes are being used for diagnosis and treatment in the human body's cavities. Because the digestive tract has the most cavities, digestive tract endoscopes are the most numerous. Taking biliary and pancreatic duct diseases as an example, in complex cases, transoral cholangioscopy is often used for further diagnosis and treatment to determine the appropriate plan. Before using transoral cholangioscopy, a routine ERCP procedure is usually performed first. In ERCP, selective cannulation of the bile duct or pancreatic duct is crucial to its success.

[0044] The conventional method for bile and pancreatic duct cannulation uses a guidewire-assisted pull-type scalpel cannulation. This involves inserting a hydrophilic, super-slippery guidewire into the duodenal papilla via the duodenal endoscope instrument channel 223, using a forceps lifter. Under fluoroscopic guidance, the guidewire is used to selectively explore the opening of the bile duct or pancreatic duct. After successful loculation, the scalpel is inserted along the guidewire into the papilla, and the papillary sphincter is cut after electrical stimulation. The guidewire extends through a small hole at the tip of the scalpel and, under fluoroscopic guidance, is inserted into the bile duct or pancreatic duct. Once the guidewire has successfully penetrated to a certain depth, the pull-type scalpel is slowly advanced along the guidewire until its tip reaches the predetermined position. Under fluoroscopic guidance, it is confirmed that the scalpel is accurately positioned within the bile duct or pancreatic duct; if the position is inaccurate, the guidewire and scalpel positions must be readjusted.

[0045] The main inventive point of this utility model is to provide an endoscope device 100 that solves the problem of existing bile and pancreatic duct cannulation failure or even organ tissue damage due to the inability to perform cannulation under direct vision. The endoscope device 100 will be described below with reference to the accompanying drawings.

[0046] Please see Figures 1 to 3 The endoscope 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. The insertion tube 12 is disposed on the main handle 11 and has a first end 121 away from the main handle 11 and a first curved section 12a near the first end 121. An instrument channel 122 for inserting consumable instruments is formed inside the insertion tube 12. An image acquisition element 3 is disposed on the first end 121. The auxiliary mechanism 2 includes an auxiliary handle 21 and a sheath 22. The auxiliary handle 21 is disposed on the main handle 11, and the sheath 22 is disposed on the auxiliary handle 21 for insertion into an organ cavity. The sheath 22 has a second end 221 away from the auxiliary handle 21 and a second curved section 22a near the second end 221. The first end 121 is movably inserted into the sheath 22 and can extend or retract from the second end 221.

[0047] The endoscope device 100 also 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 12a to bend, and the second adjustment component 42 drives the second bending segment 22a to bend.

[0048] In the endoscope device 100 provided by this utility model, the auxiliary handle 21 of the auxiliary mechanism 2 is disposed on the main handle 11 of the endoscope body 1; an insertion tube 12 is disposed on the main handle 11; a sheath 22 for inserting into an organ cavity 201 is disposed on the auxiliary handle 21, the insertion tube 12 is movably inserted into the sheath 22, and the first end 121 of the insertion tube 12 can be movably extended or retracted from the second end 221 of the sheath 22. An image acquisition element 3 is disposed on the first end 121; and an instrument channel 122 for inserting consumable instruments is formed in the insertion tube 12. A first adjustment component 41 drives the first curved section 12a of the insertion tube 12, and a second adjustment component 42 drives the second curved section 22a of the sheath 22.

[0049] Please refer to the following during the diagnosis and treatment process: Figure 4 and Figure 5 First, the sheath 22 is inserted into the patient's organ cavity 201. The insertion tube 12 is pushed so that its first end 121 extends from the second end 221. At the same time, the first bending section 12a of the insertion tube 12 is driven to bend by the first adjustment component 41. The image acquisition element 3 on the first end 121 is used to locate the target lesion 202. In other words, the insertion tube 12 is equivalent to the insertion part of the existing transoral cholangioscopy. The sheath 22 is set to replace the duodenoscope in the existing technology, providing a stable insertion path for the insertion tube 12. At the same time, the second adjustment component 42 is set to drive the second bending section 22a to bend, so as to adjust the bending angle of the head of the sheath 22, which is equivalent to the duodenoscope lifting forceps in the existing technology. In this way, by using the sheath 22 to replace the duodenoscope in the existing technology, the cost of the visualization insertion device 100 can be greatly reduced.

[0050] As mentioned above, the sheath 22 can provide a stable insertion path for the insertion tube 12 instead of a duodenoscope. However, the sheath 22 does not have image acquisition capabilities. Therefore, in the embodiments of this application, please refer to... Figure 6The image acquisition element 3 on the first end 121 of the insertion tube 12 is used to locate the target lesion 202. Unlike the lateral observation of the duodenoscopy in the prior art, the image acquisition element 3 on the first end 121 can be directly observed during the advancement of the insertion tube 12, which is more conducive to locating the target lesion. After the target lesion 202 is determined by the image acquisition element 3 on the first end 121, the insertion tube 12 is withdrawn so that its first end 121 is retracted from the second end 221. Then the sheath 22 is pushed forward, and the second curved section 22 is driven by the second adjustment component 42. The first end 121 of the insertion tube 12 is bent so that the image acquisition element 3 can directly view the target lesion 202. Finally, the insertion tube 12 is pushed so that its first end 121 reaches the target lesion 202, thereby completing the visual intubation operation. At the same time, the consumable device can be inserted from the device channel 123 and reach the target lesion 202 for treatment. In this way, when encountering tortuous or complex organ tissues, the insertion tube 12 can accurately reach the target lesion 202, achieving precise intubation and reducing the risk of organ tissue damage caused by repeated intubation attempts.

[0051] In one embodiment, please refer to Figure 1 A main channel (not shown in the figure) is formed inside the main handle 11, and a first inlet 111 communicating with the main channel is provided on the main handle 11; the insertion tube 12 is provided on the main handle 11 and communicates with the main channel, so that the consumable device can be inserted into the device channel 122 from the first inlet 111 through the main channel.

[0052] In one embodiment, please refer to Figure 1 An auxiliary channel (not shown in the figure) is formed inside the auxiliary handle 21, and a second inlet 211 communicating with the auxiliary channel is provided on the auxiliary handle 21; the sheath 22 is provided on the auxiliary handle 21 and communicates with the auxiliary channel; the first end 121 is movably inserted into the sheath 22 from the second inlet 211 through the auxiliary channel.

[0053] As described above, the endoscope device 100 includes an endoscope body 1 and an auxiliary mechanism 2, with the auxiliary handle 21 of the auxiliary mechanism 2 disposed on the main handle 11 of the endoscope body 1. This application does not impose specific restrictions on the arrangement of the auxiliary handle 21 and the main handle 11.

[0054] The insertion tube 12 and the main handle 11 are arranged along the axial direction of the insertion tube 12; the sheath tube 22 and the auxiliary handle 21 are arranged along the axial direction of the sheath tube 22; the axial direction of the insertion tube 12 and the axial direction of the sheath tube 22 are arranged in parallel, and are temporarily set as the first direction F1.

[0055] The main handle 11 has a first end face in the second direction F2, and the auxiliary handle 21 is disposed on the first end face; wherein the second direction F2 and the first direction F1 are arranged intersectingly.

[0056] This invention does not impose 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.

[0057] In one embodiment, the endoscope device 100 further includes a detachable connection structure 5, which includes a connecting part and a mating part that cooperate with each other. One of the connecting part and the mating part is disposed on the main handle 11, and the other is disposed on the auxiliary handle 21. The connecting part and the mating part enable a detachable connection between the auxiliary handle 21 and the main handle 11, which is simple in structure and easy to assemble and disassemble.

[0058] This utility model does not impose 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 fixed by thread; the auxiliary handle 21 and the main handle 11 can be fixed by snap-fit; the auxiliary handle 21 and the main handle 11 can also be fixed by plugging.

[0059] Specifically, a male buckle is provided on the main handle 11; a female buckle is provided on the auxiliary handle 21. It is understood that the male buckle is generally a component with a protrusion, hook, or tenon; the female buckle is typically a component with a groove, hole, or slot 51 to accommodate the male buckle. That is, please refer to... Figure 7 and Figure 9 The auxiliary handle 21 is provided with a slot 51; the main handle 11 is provided with a limit buckle 52, which is inserted into the slot 51; wherein, the connecting part and the mating part, one of which is provided with a slot 51 and the other is provided with a limit buckle 52.

[0060] In one exemplary embodiment, please refer to Figure 7 and Figure 9 The auxiliary handle 21 has a second end face facing the main handle 11; a boss protrudes from 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 each other, and the main handle 11 and the auxiliary handle 21 are pushed relative to each other in the first direction F1 so that the limit buckle 52 is inserted into the slot 51, thereby realizing the detachable connection of the main handle 11 and the auxiliary handle 21.

[0061] And please see Figure 1 When the auxiliary handle 21 is set on the main handle 11, the second inlet 211 on the auxiliary handle 21 is higher than the first end 121 of the insertion tube 12; at this time, the insertion tube 12 needs to be wound back so that the first end 121 can be inserted from the second inlet 211.

[0062] Continuing from the above, the first bending segment 12a is driven to bend by setting the first adjustment component 41. In one embodiment, the first adjustment component 41 includes a first driving part and a first transmission part. The first driving part is disposed 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 and the first bending segment 12a in a driving manner, so as to drive the first bending segment 12a to bend to different sides of its radial direction when the first driving part reciprocates.

[0063] Specifically, please refer to Figure 1 and Figure 2 The first drive unit includes a first rotating wheel 411 rotatably mounted on the main handle 11; the first transmission unit includes two first traction ropes (not shown in the figure), with one end of each of the two first traction ropes wound around the first rotating wheel 411 in different directions, and the other ends of the two first traction ropes respectively connected to a first bending section 12a, so that when the first rotating wheel 411 rotates in different directions, the corresponding first traction rope can be driven to pull the first bending section 12a to bend.

[0064] In other words, in actual use, the two ends of the two first traction ropes are wound around the first rotating wheel 411 in different directions. When the first rotating wheel 411 is rotated in the forward direction, one of the first traction ropes is wound tightly, and at this time, the first traction rope pulls the first curved section 12a, causing the first curved section 12a to bend to the corresponding side. When the first rotating wheel 411 is rotated in the reverse direction, the previously wound first traction rope is loosened, and the other first traction rope is wound tightly. At this time, the tightly wound first traction rope pulls the first curved section 12a, causing the first curved section 12a to bend to the other side. Using the rotating wheel and traction ropes to drive the bending of the curved section of the sheath is existing technology and will not be described in detail here.

[0065] Simultaneously, the second bending segment 22a is driven to bend by setting the second adjustment component 42. The second adjustment component 42 includes a second drive unit and a second transmission unit. The second drive unit is disposed on the main handle 11 and can reciprocate relative to the main handle 11. The second transmission unit is connected to the second drive unit and the second bending segment 22a, so as to drive the second bending segment 22a to bend to different sides of its radial direction when the second drive unit reciprocates.

[0066] Specifically, please refer to Figure 1 and Figure 2 The second drive unit includes a second wheel 421 rotatably mounted on the main handle 11; the second transmission unit includes two second traction ropes, with one end of each second traction rope wound around the second wheel 421 in different directions, and the other ends of each second traction rope connected to a second curved section 22a, so that when the second wheel 421 rotates in different directions, the corresponding second traction rope can be driven to pull the second curved section 22a.

[0067] In other words, during actual use, the two ends of the two second traction ropes are wound around the second wheel 421 in different directions. When the second wheel 421 is rotated in the forward direction, one of the first traction ropes is wound tightly. At this time, the first traction rope pulls the second curved section 22a so that the second curved section 22a bends to the corresponding side. When the second wheel 421 is rotated in the reverse direction, the previously wound first traction rope is loosened, and the other first traction rope is wound tightly. At this time, the tightly wound first traction rope pulls the second curved section 22a so that the second curved section 22a bends to the other side.

[0068] Following the above, "the auxiliary mechanism 2 also includes an auxiliary handle 21, which is mounted on the main handle 11," and a sheath 22 is mounted on the auxiliary handle 21; a second drive unit is mounted on the auxiliary handle 21 and can reciprocate relative to the auxiliary handle 21. Specifically, the second rotating wheel 421 is rotatably mounted on the auxiliary handle 21.

[0069] Understandably, during the diagnosis and treatment process, the sheath 22 is first inserted into the patient's organ cavity 201, and the insertion tube 12 is pushed so that its first end 121 extends from the second end 221. At the same time, the first bending segment 12a of the insertion tube 12 is driven to bend through the first adjustment component 41, and the image acquisition element 3 on the first end 121 is used to find the target lesion 202. When encountering difficult nipples (such as long nipples or diverticulum nipples), in order to accurately find the target lesion 202, the first bending segment 12a needs to be able to bend in multiple directions.

[0070] The adjustment mechanism 4 includes at least two sets of first adjustment components 41. The two sets of first adjustment components 41 enable the first bending segment 12a to bend in four directions.

[0071] This application does not specifically limit the arrangement of the first driving unit. In one embodiment, the movable planes of the two first driving units of the two sets of first adjustment components 41 can be arranged intersectingly or in parallel.

[0072] In one embodiment, the movable planes of the two first driving parts of the two sets of first adjustment components 41 are arranged in parallel, and the two first traction ropes of each set of first adjustment components 41 form a first traction plane. The two first traction planes formed by the two sets of first adjustment components 41 are arranged in an intersecting manner. In this way, the first bending segment 12a can be bent in four directions using four first traction ropes.

[0073] For example, two first rotating wheels 411 are provided on the main handle 11; the two first rotating wheels 411 are stacked in the second direction F2, and the two first rotating wheels 411 have the same axis of rotation. Each pair of first traction ropes is wound around one of the first rotating wheels 411; the two first traction ropes on one of the first rotating wheels 411 form a first traction plane, and the two first traction ropes on the other first rotating wheel 411 form another first traction plane. The two first traction planes are arranged in a cross pattern, so that the first bending section 12a can be bent in four directions using four first traction ropes.

[0074] It should be noted that the bending direction of the first bending segment 12a can be completely different from the bending direction of the second bending segment 22a. Among the multiple bending directions of the first bending segment 12a, some bending directions may also coincide with those of the second bending segment 22a.

[0075] In one embodiment, two first traction ropes on each set of first rotating wheels 411 form a first traction plane; two second traction ropes on the second rotating wheels 421 form a second traction plane, and the second traction plane is arranged parallel to one of the first traction planes.

[0076] Continuing from the above, by using a sheath 22 to replace the existing duodenoscope, since the 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 insertion device 100. Based on actual diagnostic and treatment operations, the insertion tube 12 also needs to have flushing and illumination functions. In one embodiment, please refer to... Figure 8 The insertion tube 12 also forms a liquid inlet channel and an illumination channel; the visualization insertion device 100 also includes a nozzle 6 and a light-emitting element 7. The nozzle 6 is disposed at the first end 121 of the insertion tube 12 and communicates with the liquid inlet channel so that the liquid in the liquid inlet channel can be ejected from the nozzle 6. The light-emitting element 7 is disposed at the first end 121 of the insertion tube 12 and its optical fiber passes through the illumination channel.

[0077] It is understood that during the diagnosis and treatment process, the sheath 22 is first inserted into the patient's organ cavity 201, and the insertion tube 12 is pushed so that its first end 121 extends from the second end 221. At the same time, the first bending section 12a of the insertion tube 12 is driven to bend through the first adjustment component 41, and the image acquisition element 3 on the first end 121 is used to locate the target lesion 202. After the target lesion 202 is determined by the image acquisition element 3 on the first end 121, the insertion tube 12 is pulled back so that its first end 121 retracts from the second end 221. The sheath 22 is then pushed, and the second bending section 22a is driven to bend through the second adjustment component 42 so that the image acquisition element 3 on the first end 121 can directly view the target lesion 202.
