DETAILED DESCRIPTION

[0058] In order to make the purpose, technical solutions and advantages of this specification more clear, the technical solutions of this specification will be clearly and completely described below in combination with the specific embodiments of this specification and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0059] In the description of the present invention, it should be noted that the term "or" is generally used in a sense including "and / or", unless the content clearly indicates otherwise.

[0060] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. In addition, in the description of the present application, the terms "first", "second" and the like are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0061] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0062] In particular, in the description of the present invention, those skilled in the art should understand that, unless otherwise clearly specified and limited, the terms "proximal end" and "distal end" are relative to the operator; the "proximal end" is the end of the detachable endoscope that is closer to the user in one dimension when it is held and operated, and the "distal end" is the end of the detachable endoscope that is farther away from the user in one dimension when it is held and operated. And those skilled in the art should understand that "far" and "near" do not refer to the three-dimensional space straight-line distance from the user.

[0063] Usually, an endoscope is equipped with a control unit and a camera, and the user can control the direction of the catheter through the control unit and collect images through the camera. In the prior art, detachable endoscopes generally integrate the control unit, camera and other structures into a disposable part, resulting in the control unit, camera and other components being only usable once, which is costly.

[0064] The technical solutions provided by the embodiments of this specification are described in detail below in conjunction with the accompanying drawings.

[0065] Figure 1 The schematic diagram of the structure of a detachable endoscope provided in one embodiment of the present specification. Figure 1As shown, the detachable endoscope includes a handle portion 1 and a disposable portion 2.

[0069] Preferably, the control assembly 11 is fixedly connected to the first housing 12, such as Figure 1 shown.

[0070] Preferably, part of the structure of the control component 11 is exposed outside the first shell 12 , and the rest of the structure is accommodated by the first shell 12 , and the part of the structure exposed outside the first shell 12 is fixedly connected to the part of the structure accommodated by the first shell 12 .

[0071] Preferably, the partial structure contained in the first housing 12 is respectively connected to the n first traction wires 13. The partial structure exposed to the outside of the first housing 12 can drive any first traction wire 13 to move toward and away from the proximal end of the first housing 12 in response to the user's operation through the partial structure contained in the first housing 12.

[0072] Preferably, part of the structure of the control component 11 is exposed outside the housing so that the user can operate it.

[0073] Preferably, part of the structure of the control component 11 is accommodated inside the housing and linked with other structures.

[0074] Those skilled in the art will appreciate that the technology related to the control component 11 has been relatively mature, and this specification does not describe in detail the specific structure of the control component 11, nor does it limit the structure of the control component 11. The control component 11 may adopt any related structure commonly found in the art.

[0075] Preferably, the control component 11 is connected to the proximal ends of the n first traction wires 13 respectively, and can drive any one of the first traction wires 13 to move toward and away from the proximal end of the first housing 12 .

[0076] Preferably, the distal end of any first traction wire 13 is provided with a distal interface 131 .

[0077] Figure 3 FIG. 1 is a schematic diagram of the structure of the remote interface 131 provided in one embodiment of the present specification. Figure 3 As shown, n distal interfaces 131 are respectively configured at the distal ends of the n first traction wires 13 .

[0078] Preferably, the disposable portion 2 can be discarded after being used a preset number of times, which can be 1, 2, 3, 4, etc.

Figure 4 As shown, the second shell 21 is fixedly connected to the traction catheter 22 , and n second traction wires 23 are exposed outside the proximal end of the second shell 21 .

[0082] Preferably, the second housing 21 can be detachably connected to the first housing 12. Those skilled in the art will appreciate that the connection technology of mechanical parts has been relatively mature, and this specification will not describe in detail the structure of the connection between the first housing 12 and the second housing 21, nor will it limit the structure of the connection between the first housing 12 and the second housing 21. The connection between the first housing 12 and the second housing 21 can adopt any detachably connected structure commonly used in the art.

[0083] Preferably, the proximal ends of the n second traction wires 23 are each provided with a proximal interface 231 .

[0084] Preferably, the n proximal interfaces 231 are all exposed outside the second housing 21. Figure 4 As shown, the n proximal interfaces 231 are all arranged on the outside of the second shell 21 .

[0085] Preferably, the distal ends of the n second traction wires 23 are all connected to the distal end of the traction catheter 22 .

[0086] Figure 5 This is a partial structural diagram of a disposable portion 2 provided in one embodiment of the present specification. Figure 5 As shown, the n second traction wires 23 are respectively located at different positions around the traction catheter 22 , and the proximal ends of the n second traction wires 23 are all provided with proximal end interfaces 231 .

[0087] It is understood by those skilled in the art that when the first traction wire 13 and the second traction wire 23 move toward the proximal end of the first housing 12, they can drive one end of the traction catheter 22 to deviate therefrom, thereby changing the travel direction of the traction catheter 22. Therefore, in a preferred embodiment of the present specification, different second traction wires 23 are connected to different positions of the traction catheter 22, such as Figure 5 shown.

[0088] Preferably, the proximal interfaces 231 can be detachably connected to the corresponding distal interfaces 131 .

[0089] Figure 6 This is a schematic diagram of a structure in which a proximal interface 231 and a distal interface 131 are detachably connected to each other in accordance with an embodiment of the present specification. Figure 6 As shown, the proximal interface 231 and the distal interface 131 are connected to each other.

[0090] Preferably, the second shell 21 is provided with an absorption conduit 212 and a flushing conduit 211 .

[0091] Preferably, an instrument channel and at least one gas-liquid channel 2143 are provided at the end of the traction catheter 22 .

[0092] Preferably, the flushing conduit 211 and / or the absorption conduit 212 is communicated with at least one gas-liquid channel 2143 .

[0093] Preferably, both the flushing conduit 211 and the absorption conduit 212 are connected to at least one gas-liquid channel 2143, and the gas-liquid channels 2143 connected to the flushing conduit 211 and the absorption conduit 212 are different.

[0094] Preferably, the flushing catheter 211 or the absorption catheter 212 is communicated with the instrument channel.

[0095] Preferably, the flushing conduit 211 is connected to at least one gas-liquid channel 2143, and the absorption conduit 212 is connected to the instrument channel.

[0096] Preferably, the absorption conduit 212 is connected to at least one gas-liquid channel 2143, and the flushing conduit 211 is connected to the instrument channel.

[0097] Preferably, the flushing conduit 211 and the absorption conduit 212 are respectively connected to at least one different gas-liquid channel 2143, and the absorption conduit 212 is also connected to the instrument channel.

[0098] Those skilled in the art can understand that both the flushing catheter 211 and the absorption catheter 212 may come into direct contact with the patient's body fluids, so both the flushing catheter 211 and the sound absorption catheter are structures of the disposable part 2.

[0099] like Figure 4 As shown, the flushing conduit 211 and the absorption conduit 212 are both fixedly connected to the second shell 21 .

[0100] Preferably, the absorption conduit 212 can be detachably connected to other medical devices and can allow substances to pass through, including liquids.

[0101] Preferably, the flushing catheter 211 can be detachably connected to other medical devices and can allow the substance to pass through.

[0102] Preferably, the first shell 12 and / or the second shell 21 is equipped with a docking compartment 121 .

[0103] Preferably, the docking compartment 121 can accommodate the proximal interface 231 and / or the distal interface 131 and / or the proximal interface 231 and the distal interface 131 that are connected to each other.

[0104] Figure 7 FIG. 1 is a schematic diagram of the structure of the first housing 12 provided in one embodiment of the present specification. Figure 7 As shown, the docking chamber 121 is disposed in the first housing 12 , and the docking chamber 121 accommodates the remote interface 131 .

[0105] Preferably, the docking compartment 121 accommodates the distal interface 131 and is capable of accommodating the proximal interface 231 and the distal interface 131 that are connected to each other.

[0106] Preferably, the docking chamber 121 accommodates the proximal interface 231 and is capable of accommodating the proximal interface 231 and the distal interface 131 that are connected to each other.

[0107] In the detachable endoscope provided by one or more of the above-mentioned embodiments, the distal interfaces 131 of the n first traction wires 13 arranged in the control part can be detachably connected with the proximal interfaces 231 of the n second traction wires 23 arranged in the disposable part 2. The proximal end of the first traction wire 13 is connected to the control component 11, and the distal end of the second traction wire 23 is fixedly connected to the distal end of the traction catheter 22. The first traction wire 13 can drive the traction catheter 22 to deflect through the second traction wire 23 under the drive of the control component 11, thereby controlling the travel direction of the traction catheter 22. Among them, the proximal interface 231 and the distal interface 131 can be detachably connected in the docking chamber 121 provided on the first shell 12 and / or the second shell 21. In addition, the second shell 21 is also provided with a flushing catheter 211 and an absorption catheter 212.

[0108] It can be seen from the above-mentioned device that the detachable endoscope designs the complete traction wire to have two ends that can be detachably connected, so that the control component 11 configured therein 1 can be recycled, thereby reducing the use cost of the detachable endoscope.

[0109] Preferably, the outer surface of the distal interface 131 is configured with at least one distal protrusion 1311 and at least one distal groove 1312 .

[0110] Figure 8 FIG. 1 is a schematic diagram of the structure of the remote interface 131 provided in one embodiment of the present specification. Figure 8 As shown, the surface of the distal interface 131 is configured with a plurality of distal protrusions 1311 and a plurality of distal grooves 1312 .

[0111] Preferably, the outer surface of the proximal interface 231 is configured with at least one proximal protrusion and at least one proximal groove. The shapes of the proximal protrusion and the proximal groove can be referred to Figure 8 The shapes of the mid-distal protrusion 1311 and the distal groove 1312.

[0112] Preferably, the shapes, positions and sizes of the at least one distal protrusion 1311, the at least one proximal groove, the at least one proximal protrusion and the at least one distal groove 1312 are adapted to each other, so that when the proximal protrusion is just embedded in the distal groove 1312, the distal protrusion 1311 is also just embedded in the proximal groove. It should be noted that the proximal protrusion can just be embedded in the distal groove 1312, and the distal protrusion 1311 can just be embedded in the proximal groove.

[0113] Fig. 9 This is a schematic diagram of a structure in which a proximal interface 231 and a distal interface 131 are detachably connected to each other in accordance with an embodiment of the present specification.

[0114] Preferably, the distal interface 131 is configured with at least one distal magnetic member 1313 .

[0115] Preferably, the proximal interface 231 is configured with at least one proximal magnetic member 2311 .

[0116] Preferably, the positions and magnetism of the at least one distal magnetic piece 1313 and the at least one proximal magnetic piece 2311 are adapted to each other, so that when the distal protrusion 1311 is embedded in the proximal groove, any one of the distal magnetic pieces 1313 can be tightly attached to at least one of the proximal magnetic pieces 2311, and the magnetism of the distal magnetic piece 1313 and the proximal magnetic piece 2311 that are tightly attached to each other are opposite.

Fig.10 As shown, the distal protrusion 1311 is about to be embedded in the proximal groove, and the distal magnetic member 1313 is about to be closely attached to the proximal magnetic member 2311. It should be noted that the magnetism of the distal magnetic member 1313 and the proximal magnetic member 2311 that are closely attached to each other is opposite.

[0118] Preferably, the docking compartment 121 is provided with n limiting grooves 122 , and the limiting grooves 122 are used to accommodate the distal interface 131 , and are also used to accommodate the detachably connected proximal interface 231 and the distal interface 131 .

[0119] Preferably, the positions, shapes and sizes of the limiting groove 122, the proximal interface 231 and the distal interface 131 are adapted to each other, so that when the limiting groove 122 accommodates the detachably connected proximal interface 231 and the distal interface 131, the mutually connected proximal interface 231 and the distal interface 131 can be restricted from moving in directions other than approaching and moving away from the proximal end of the first housing 12. In other words, the size of the limiting groove 122 can just accommodate the mutually connected proximal interface 231 and the distal interface 131, so that when the proximal interface 231 and the distal interface 131 are accommodated by the limiting groove 122, they cannot be relatively displaced and cannot be separated, thereby ensuring the stability of the detachable endoscope.

[0120] Fig.11 This is a partial structural diagram of a detachable endoscope provided in accordance with an embodiment of the present specification. Fig.11 As shown, the limiting groove 122 can just accommodate the proximal interface 231 and the distal interface 131 that are connected to each other.

[0121] Preferably, the length of the limit groove 122 is greater than the length of the interconnected proximal interface 231 and the distal interface 131, so that the interconnected proximal interface 231 and the distal interface 131 can still be accommodated by the limit groove 12 when moving toward and away from the proximal end of the first shell 12, and are still restricted from moving in directions other than toward and away from the proximal end of the first shell 12.

[0122] Preferably, the docking chamber 121 is disposed on the first housing 12 .

[0123] Preferably, the docking chamber 121 is configured on the second housing 21 .

[0124] Preferably, the docking compartment 121 includes at least two components, and at least one component is configured on the first shell 12 , and the other components are configured on the second shell 21 .

[0125] Preferably, the docking chamber 121 includes a movable part 1211 and a fixed part 1212 .

[0126] Preferably, the movable member 1211 and the fixed member 1212 can be detachably connected.

[0128] like Fig. 9 As shown, in the docking chamber 121 , the movable member 1211 can be pushed and pulled, thereby closing / exposing the fixed member 1212 .

[0129] Preferably, the connection positions of the traction catheter 22 and the n second traction wires 23 are different, so that when the control component 11 drives different first traction wires 13 to move toward the direction close to the proximal end of the first shell 12, the traction catheter 22 can be driven to bend in different directions through the second traction wire 23.
