[0001] The present application belongs to the field of medical device technology, and specifically relates to an endoscope and a disposable section thereof. Background Art

[0002] An endoscope is a medical diagnostic instrument, which usually includes an operating handle and an insertion part. The insertion part can be inserted into the human body, and the internal tissues of the human body can be observed through the camera module encapsulated at its far end. It can help doctors determine the location of lesions in the patient's body and the tissue structure characteristics of the lesion location. The operating handle can be used to adjust the posture of the curved section of the insertion part, thereby adjusting the direction of the camera module and realizing functions such as fixed-point observation.

[0003] In the related art, there is a detachable endoscope, which includes a disposable section and a reuse section. The disposable section is provided with an installation channel. When using the endoscope, the surgeon can first assemble the camera assembly of the reuse section to a preset position in the installation channel. After use, the camera assembly is pulled out for reuse and the disposable section is discarded. This can solve the problem of cross infection and reduce the cost of discarding the endoscope. However, in practice, it is difficult for the surgeon to assemble the camera assembly to the preset position in the installation channel. Summary of the invention

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0032] The endoscope and its disposable section provided in the embodiment of the present application are described in detail below through specific embodiments and their application scenarios in combination with the accompanying drawings.

[0033] In each embodiment of the present application, "proximal end" and "distal end" refer to the position of the endoscope and its components relative to the user in the use environment, wherein the end closer to the user is designated as the "proximal end" and the end farther from the user is designated as the "distal end".

[0034] The inventor found that the camera assembly in the related art includes a camera module and a cable, and the camera module is connected to the cable. During assembly, the cable is pushed by hand to insert the camera module into the installation channel and install the camera module to a preset position in the installation channel. However, the cable is long and its aspect ratio is very large, so the cable has low rigidity and good flexibility, and is prone to deformation. When the cable is subjected to thrust, the thrust is unevenly distributed on the cable, which causes a part of the cable to be subjected to greater stress, while other parts are subjected to relatively less stress. This unevenly distributed stress causes the cable to bend. After the cable is bent, the thrust cannot be transmitted to the camera module and the camera module can no longer be pushed to move. Therefore, it is difficult to install the camera module to a preset position.

[0035] like Figures 1 to 7 ,as well as Figures 14 to 17 As shown, an embodiment of the present application discloses a disposable section 100 of an endoscope, wherein an installation channel 101 is provided in the disposable section 100, and the installation channel 101 is used to install a camera assembly 210 of a multiplexing section 200 of an endoscope. Exemplarily, the camera assembly 210 may include a camera module 211 and a cable 212, wherein the camera module 211 is connected to the cable 212, and the camera module 211 may be powered and signal may be transmitted through the cable 212, wherein the cable 212 has a certain length. Further, the camera module 211 may include an imaging assembly, wherein the imaging assembly includes a lens and an image sensor, and images of the human body may be collected through the lens and the image sensor. Furthermore, the camera module 211 may also include a light source, and the light source may provide illumination for the imaging assembly.

[0036] A first opening is formed at the proximal end of the disposable section 100, and a second opening is formed at the distal end of the disposable section 100, and both the first opening and the second opening are connected to the installation channel 101. Specifically, the camera assembly 210 can enter the installation channel 101 through the first opening, and the guide member 300 can pass through the installation channel 101 through the second opening. For example, when the distal end of the guide member 300 is pulled, the camera assembly 210 continuously moves toward the direction close to the second opening, and the guide member 300 continuously passes through the second opening, and the camera assembly 210 can collect images inside the human body through the second opening.

[0037] The installation channel 101 is pre-pierced with a guide member 300. The pre-piercing here means that the guide member 300 is inserted into the installation channel 101 before the disposable section 100 leaves the factory. That is to say, the guide member 300 can be inserted into the installation channel 101 during the processing of the disposable section 100. At this time, the main body of inserting the guide member 300 is the manufacturer, and it is relatively easy for the manufacturer to insert the guide member 300. It should be noted that the guide member 300 here can be a structural member with relatively large rigidity, such as iron wire, etc.; or the guide member 300 can also be a structural member with relatively small rigidity, such as a flexible rope. At this time, the flexible rope can be inserted into the installation channel 101 using a guide wire.

[0038] The proximal end of the guide member 300 is used to connect with the camera assembly 210. Exemplarily, the proximal end of the guide member 300 can extend out of the first opening to facilitate connecting the camera assembly 210 to the proximal end of the guide member 300, where the connection between the guide member 300 and the camera assembly 210 can be knotted or bonded, such as glue bonding, double-sided adhesive bonding, etc. In addition, the proximal end of the guide member 300 may not extend out of the first opening. In this case, the connecting seat 320 described below can be formed at the proximal end of the guide member 300, and the guide member 300 is connected to the camera assembly 210 through the connecting seat 320. Of course, when the connecting seat 320 described below is not formed at the proximal end of the guide member 300, the proximal end of the guide member 300 may not extend out of the first opening, that is, all parts of the proximal end of the guide member 300 are located in the installation channel 101. At this time, the proximal end of the guide member 300 is arranged adjacent to the first opening, and the proximal end of the guide member 300 can be pulled out of the first opening by conventional tools such as tweezers to facilitate its connection with the camera assembly 210.

[0039] The distal end of the guide 300 is used for pulling. Figure 1The distal end of the guide member 300 may extend out of the second opening, that is, the distal end of the guide member 300 is located outside the installation channel 101, which is more convenient for pulling; alternatively, the distal end of the guide member 300 may not extend out of the second opening. In this case, the distal end of the guide member 300 is located inside the installation channel 101, and the distal end of the guide member 300 can be pulled out of the second opening by conventional tools such as tweezers for easy pulling.

[0040] It should be noted that the subject of pulling here may be a user such as a surgeon, a clamping device, etc. The surgeon or the clamping device can pull the guide member 300 to locate the camera assembly 210 at a preset position in the installation channel 101. In addition, after the guide member 300 is pulled to install the camera assembly 210 at the preset position of the installation channel 101, the guide member 300 can be separated from the camera assembly 210 first, and then the assembled endoscope can be inserted into the human body.

[0041] In the present application, a guide member 300 is pre-pierced in the installation channel 101 of the disposable section 100. When assembling the camera assembly 210, the proximal end of the guide member 300 can be first connected to the camera assembly 210, and then the distal end of the guide member 300 is pulled to install the camera assembly 210 to the preset position in the installation channel 101. In the process of pulling the guide member 300, the pulling force is evenly distributed along the entire length of the rope, so that the guide member 300 is evenly subjected to tension as a whole, thereby preventing the guide member 300 from being locally deformed and bent, which allows the guide member 300 to stably transmit the tension to the camera assembly 210, allowing the camera assembly 210 to continue to move under the action of the tension, thereby reducing the difficulty of assembling the camera assembly 210 to the preset position in the installation channel 101.

[0042] In some embodiments, the guide member 300 may only include the guide rope 310, and the proximal end of the guide rope 310 may be connected to the camera assembly 210 by bonding, hot melting, bundling, or the like.

[0043] In order to ensure the connection stability between the guide member 300 and the camera assembly 210 and to ensure the convenience of disassembly between the guide member 300 and the camera assembly 210, in an optional embodiment, refer to Fig.10 The guide member 300 includes a guide rope 310 and a connecting seat 320 . The connecting seat 320 is connected to the proximal end of the guide rope 310 . A connecting structure is formed on the connecting seat 320 , and the connecting structure can be detachably connected to the camera assembly 210 .

[0044] In this embodiment, the guide 300 includes a guide rope 310 and a connection seat 320. The camera assembly 210 can be connected to the connection structure on the connection seat 320. The camera assembly 210 and the guide 300 are connected through the connection structure, which can ensure the connection strength between the two. The camera assembly 210 can also be disconnected from the guide 300 through the connection structure, so that the two are easily removable. It can be seen that after adopting the structure of this embodiment, the connection stability between the guide 300 and the camera assembly 210 can be ensured, while ensuring the convenience of disassembly between the guide 300 and the camera assembly 210.

[0045] In an alternative embodiment, see Figure 4 and Fig.11 , the camera assembly 210 includes a camera module 211, and a accommodating cavity 321 is provided in the connecting seat 320. A mounting port connected to the accommodating cavity 321 is provided on the connecting seat 320. The accommodating cavity 321 is used to accommodate at least part of the camera module 211 along its own axis, and a light-transmitting portion 322 is provided at the portion of the connecting seat 320 opposite to the mounting port. Specifically, after the camera module 211 is installed in the accommodating cavity 321, the light-transmitting portion 322 is arranged opposite to the camera module 211, and the light-transmitting portion 322 is capable of transmitting light, so that the light irradiated into the human body by the light source can be reflected into the camera module 211 through the light-transmitting portion 322; when the camera module 211 includes an imaging component and a light source, the light-transmitting portion 322 is respectively arranged opposite to the imaging component and the light source. Of course, the connecting seat 320 can also be a cylindrical structural member, a plate-like structural member, etc., and the present application does not limit the structure of the connecting seat 320.

[0046] In this embodiment, the connecting seat 320 has a accommodating cavity 321. When the camera module 211 is connected to the connecting seat 320, at least part of the camera module 211 along its own axis will be located in the accommodating cavity 321, that is, the camera module 211 will be axially covered by the connecting seat 320. In this way, when the camera module 211 is installed at the preset position of the installation channel 101 and a part of the disposable segment 100 is inserted into the human body, the connecting seat 320 can prevent tissue fluid, tissue, etc. in the human body from contacting with the camera module 211 and contaminating the camera module 211, thereby ensuring the cleanliness of the camera module 211 and facilitating the reuse of the reuse segment 200.

[0047] It should be noted that after adopting the structure of this embodiment, after the camera module 211 is assembled to the preset position in the installation channel 101 using the guide 300, the guide rope 310 can be separated from the connecting seat 320, and the connection between the connecting seat 320 and the camera module 211 can be maintained; after the assembled endoscope is pulled out of the human body after the operation, the connecting seat 320 can be separated from the camera module 211.

[0048] For example, the proximal end of the guide rope 310 may be embedded in the connection seat 320, or the proximal end of the guide rope 310 may be connected to the connection seat 320 by gluing; in both cases, the proximal end of the guide rope 310 may be cut off to separate the guide rope 310 from the connection seat 320. Figure 4 As shown, the outlet of the guide rope 310 from the connecting seat 320 is located on the outer peripheral surface of the connecting seat 320, so as to avoid cutting the guide rope 310 remaining on the connecting seat 320 to obstruct the field of view of the camera module 211.

[0049] In an optional embodiment, please continue to refer to Fig.10 The connecting structure is a snap-fit ​​structure 3241. Along the axial direction of the connecting seat 320, the orthographic projection of the snap-fit ​​structure 3241 is located within the orthographic projection of the accommodating cavity 321. An avoidance channel 325 is formed on one side of the snap-fit ​​structure 3241. The avoidance channel 325 is used to avoid the camera module 211 so that the camera module 211 extends into the accommodating cavity 321, and the camera module 211 can be rotatably snap-fitted with the snap-fit ​​structure 3241.

[0050] The process of connecting the camera module 211 and the connecting base 320 using the structure of this embodiment is as follows: align the portion where the camera module 211 and the connecting base 320 are engaged (when the camera module 211 is square, the portion can be the corner of the camera module 211) with the avoidance channel 325, and insert the camera module 211 into the accommodating cavity 321. During this process, the camera module 211 will pass over the engaging structure 3241 via the avoidance channel 325, so that the camera module 211 is located below the engaging structure 3241 (with the camera module 211 being located below the engaging structure 3241). Fig.10 The camera module 211 is then rotated to make it fit with the snap-fit ​​structure 3241, thereby snap-fitting the camera module 211 with the connecting seat 320, so that the camera module 211 and the connecting seat 320 are positioned at the axial upper limit of the connecting seat 320, and the camera module 211 will move under the pull of the guide rope 310; when disassembling the camera module 211 and the connecting seat 320, the camera module 211 is rotated to make it opposite to the avoidance channel 325, so that the camera module 211 can be separated from the connecting seat 320. It can be seen that the present embodiment opens an avoidance channel 325 on the connection base 320, and adopts a rotating snap connection method to detachably connect the camera module 211 and the connection base 320. Compared with the ordinary snap connection method, the present embodiment can reduce the resistance generated when the camera module 211 and the connection base 320 are connected, thereby reducing the connection difficulty between the camera module 211 and the connection base 320. Of course, the connection structure can also be a threaded structure, and the present application does not limit the specific type of the connection structure.

[0051] In some embodiments, the snap-fit ​​structure 3241 may be at least two arc-shaped protrusions disposed on the connection seat 320 , each arc-shaped protrusion being spaced apart along the circumference of the connection seat 320 , and an avoidance channel 325 is formed between two adjacent arc-shaped protrusions.

[0052] In an alternative embodiment, see Figure 2 , Figure 4 and Figures 8 to 13 The connection seat 320 includes a seat body 323 and at least two elastic arms 324. The accommodating cavity 321 is disposed in the seat body 323. Each elastic arm 324 is connected to the seat body 323 and is distributed along the circumference of the seat body 323. The elastic arms 324 have a clamping structure 3241. Fig.11 Taking the perspective shown as an example, the clamping structure 3241 here can be the lower edge of the elastic arm 324; or, the clamping structure 3241 can also be a protrusion protruding from the inner plate surface of the elastic arm 324.

[0053] The elastic arm 324 has a first position ( Fig.10 and Fig.11 As shown in the position, in the first position, the snap-on structure 3241 can press the camera module 211 and apply a force on the camera module 211 in a direction extending from the mounting opening toward the light-transmitting portion 322, so that the camera module 211 can be squeezed and abutted against the seat body 323, thereby enhancing the connection stability between the camera module 211 and the connecting seat 320.

[0054] The elastic arm 324 can switch from the first position to the second position when subjected to an outward extrusion force. Fig.12 and Fig.13 As shown in the position), in the second position, the clamping structure 3241 can release the camera module 211 and form a movable gap 410 between the clamping structure 3241 and the camera module 211.

[0055] The specific working process of this embodiment is as follows: before assembling the camera module 211 to the connecting seat 320, an outward squeezing force is first applied to the elastic arm 324, so that the elastic arm 324 moves outward and deforms with the connection between itself and the seat body 323 as the base point. During this process, the distance between the clamping structure 3241 on the elastic arm 324 and the light-transmitting portion 322 will increase. In this way, after the camera module 211 is located under the clamping structure 3241, a movable gap 410 can be formed between the two, thereby avoiding contact between the camera module 211 when rotating relative to the clamping structure 3241, so as to avoid friction between the two, and then the camera module 211 can be easily rotated to a preset position, so as to reduce the difficulty of matching the camera module 211 with the clamping structure 3241. After the camera module 211 is rotated into position, the elastic arm 324 is released and the elastic arm 324 will restore its deformation under its own elastic action. The elastic arm 324 will move inward with the above-mentioned base point, thereby pressing the camera module 211 and squeezing the camera module 211 against the seat body 323 to enhance the connection stability between the camera module 211 and the connecting seat 320.

[0056] Exemplarily, the structure of the elastic arm 324 can be an elastic structural member, which can be a plate-shaped or rod-shaped structural member; or the elastic arm 324 can include an elastic member and a rigid arm, and the elastic member is respectively connected to the rigid arm and the seat body 323, and the elastic member can drive the rigid arm to switch from the second position to the first position. For example, the elastic member can be a torsion spring.

[0057] In order to further simplify the steps of connecting the camera module 211 to the connection base 320, in an optional embodiment, refer to Figure 3 and Fig. 9 A slot 1011 is formed at the proximal end of the installation channel 101, and each elastic arm 324 can be engaged with the slot 1011, and the inner wall of the slot 1011 can apply an outward extrusion force to the elastic arm 324, so that the elastic arm 324 is elastically deformed and located at the second position. Exemplarily, the inner wall of the slot 1011 that squeezes the elastic arm 324 can be in an inverted cone shape.

[0058] In this embodiment, a slot 1011 is formed at the proximal end of the installation channel 101, and the connecting seat 320 is located at the proximal end of the installation channel 101, and the elastic arm 324 of the connecting seat 320 extends into the slot 1011 and is engaged with the slot 1011, which can prevent the elastic arm 324 from detaching from the slot 1011, and when the elastic arm 324 is engaged with the slot 1011, the inner wall of the slot 1011 can exert an outward squeezing force on the elastic arm 324, so that the elastic arm 324 is located in the second position. In this way, when the surgeon connects the camera module 211 with the connecting seat 320, there is no need to pry open the elastic arm 324 to make it located in the second position, which can simplify the steps of connecting the camera module 211 with the connecting seat 320.

[0059] In order to make the camera module 211 accurately located at a preset position in the installation channel 101, in an optional embodiment, refer to Figure 4 The distal end of the installation channel 101 includes a tapered section 1012. In the direction extending from the proximal end to the distal end of the installation channel 101, the cross-sectional area of ​​the tapered section 1012 gradually decreases. The connecting seat 320 can cooperate with the inner wall of the tapered section 1012 in the direction extending from the proximal end to the distal end of the installation channel 101.

[0060] In this embodiment, after the camera module 211 at the proximal end of the guide member 300 is connected, the distal end of the guide member 300 can be pulled until it cannot be pulled. At this time, the connection seat 320 is just limited to the necking section 1012, and the camera module 211 is just installed to the preset position. It can be seen that the structure of this embodiment does not need to deliberately determine the position where the camera module 211 is pulled, and the assembly is simple. It should be noted that the outer peripheral surface of the connection seat 320 also has a matching section that matches the necking section 1012. In the direction extending from the proximal end to the distal end of the connection seat 320, the cross-sectional area of ​​the matching section gradually decreases. The matching section of the connection seat 320 can be limited to the inner wall of the necking section 1012 in the direction extending from the proximal end to the distal end of the installation channel 101.

[0061] Optionally, the disposable section 100 may include a channel assembly 130, the channel assembly 130 includes a channel tube 131 and a clamping tube 132, the proximal end of the channel tube 131 is connected to the clamping tube 132, the installation channel 101 is arranged in the clamping tube 132 and the channel tube 131, the clamping tube 132 is provided with the above-mentioned clamping groove 1011, and the distal end of the channel in the channel tube 131 has the above-mentioned constriction section 1012. It should be noted that the clamping tube 132 here can be arranged in the operating handle 110 of the disposable section 100.

[0062] In an alternative embodiment, see Figure 5 and Fig.14 The disposable section 100 includes a connected operating handle 110 and an insertion portion 120, and the mounting channel 101 extends from the operating handle 110 to the insertion portion 120. A first opening is formed on the operating handle 110, and a second opening is formed at the distal end of the insertion portion 120. Exemplarily, the second opening can be formed on the distal surface or the peripheral surface of the insertion portion 120, and the present application is not limited to this. In this embodiment, the distal end of the operating handle 110 is connected to the proximal end of the insertion portion 120, and the surgeon can perform the surgical operation by holding the operating handle 110, and the insertion portion 120 can be inserted into the human body.
