[0019] The following description provides many different embodiments or examples for implementing different features of the present invention. The components and arrangements described in the following specific examples are only used to simplify the present invention and are only used as examples, not to limit the present invention.

[0020] It should be noted that, in each embodiment of the present application, "proximal end" and "distal end" refer to the position of the endoscope and its accessories 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".

[0021] The embodiment of the present application provides a separate insert portion, referring to Figures 1 to 7 As shown, the insertion portion 100 has at least one dividing surface, which passes through the distal end surface of the insertion portion 100 and extends toward the proximal end of the insertion portion 100. The at least one dividing surface divides the insertion portion 100 into at least two insertion sub-portions 110. The dividing surface passes through the distal end surface of the insertion portion 100, so that the insertion sub-portions 110 are separated from the distal end of the insertion portion 100, and each insertion sub-portion 110 can be bent in different directions to meet the doctor's operation requirements during surgery.

[0022] Any two adjacent insertion sub-sections 110 are connected by the connecting member 200, so that all the insertion sections 100 can be connected together to form an integral structure. Figure 4 When using the endoscope, it is only necessary to insert the whole structure formed by connecting all the insertion parts 100 into the human body and perform one insertion action, so that all the insertion sub-parts 110 can smoothly reach the affected part, thereby improving the insertion efficiency of the insertion part 100 and simplifying the insertion steps.

[0023] All the insertion sub-sections 110 are connected to a traction structure, which is used to drive the insertion sub-section 110 to bend, so that the insertion sub-section 110 bends at a preset angle and performs a corresponding operation. In addition, when the traction structure drives the insertion sub-section 110 to bend, it is only necessary to control the bending actions of two adjacent insertion sub-sections 110 to be different, so that the insertion sub-section 110 can be separated from the insertion sub-section 110 connected to it. Figure 1 and Figure 3 As shown, the connecting member 200 connecting the two insertion sub-sections 110 loses its connection function. Each insertion sub-section 110 can change its bending angle under the drive of the traction structure, referring to Figure 5 and Figure 7 As shown, it is adapted to the doctor's operation during surgery, thereby improving the convenience of using the endoscope. The traction structure usually selects a traction rope.

[0024] Compared with the related art, the insertion part 100 provided in the embodiment of the present application only needs one insertion action to smoothly deliver all the insertion sub-parts 110 to the affected part. Compared with the endoscope with multiple insertion parts 100 that needs multiple insertions in the prior art, the insertion part 100 provided in the embodiment of the present application is more convenient to operate, and the insertion efficiency of the insertion part 100 is higher; and all the insertion sub-parts 110 can form a whole under the connection of the connector 200, and the size of the insertion part 100 can be minimized, so that the insertion action of the insertion part 100 is smoother. During the process of the insertion part 100 being inserted into the human body, the connector 200 can ensure that all the insertion sub-parts 110 are connected to form an integral structure to avoid dispersing in the middle and affecting the insertion action of the insertion part 100, and use the traction structure to release the connection effect of the connector 200 to ensure the normal use of the insertion sub-parts 110.

[0025] In some embodiments, in order to reduce the size of the insertion sub-section 110 and to more conveniently control the bending direction of the insertion section 100, the insertion sub-section 110 is connected to only one traction structure, and the insertion sub-section 110 is pre-set in a pre-bending direction during the manufacturing process. When the traction structure is tightened, the control force on the insertion sub-section 110 is increased, and the insertion sub-section 110 can be driven to bend in a direction opposite to its pre-bending direction. When the traction structure is loosened, the control force on the insertion sub-section 110 is weakened, and the insertion sub-section 110 moves in the pre-bending direction. In such a layout, the two bending directions of the insertion sub-section 110 can be controlled by a traction structure, thereby improving the convenience of use of the insertion sub-section 110.

[0026] In some other embodiments, two traction structures may be connected to the insertion sub-section 110 , and the two traction structures may be used to control the insertion sub-section 110 to bend in two directions.

[0027] The connector 200 connecting adjacent insertion sub-sections 110 may choose to use a disposable connection structure. After the traction structure drives the insertion sub-sections 110 to bend and releases the connection effect of the connector 200, the connector 200 cannot be used again. Even if the traction structure controls the adjacent insertion sub-sections 110 to fit together again, the two adjacent insertion sub-sections 110 cannot be connected again. Exemplarily, the connector 200 may be an adhesive structure, and the two insertion sub-sections 110 are connected together by glue. A reusable glue is selected, and the two adjacent insertion sub-sections 110 are subsequently pulled apart by the traction structure. Since the adjacent insertion sub-sections 110 are separated, the connector 200 is exposed to the human body and contaminated. Even if the two adjacent insertion sub-sections 110 fit together again, the connector 200 cannot connect the two. Alternatively, the connector 200 may be a structure that can be destroyed after one connection, such as a connecting strip fixed between two adjacent insertion sub-sections 110, with a pre-set fracture on the connecting strip, and the insertion sub-section 110 is pulled by the traction structure, so that the pre-set fracture of the connecting strip is stressed, causing the connecting strip to break, and the adjacent two insertion sub-sections 110 to separate. The connector 200 may also be a structure with other connecting functions, and the specific structural forms of the connector 200 are not listed one by one in this application.

[0028] In other embodiments, the connector 200 may be a connection structure that can be used multiple times. For example, the connector 200 may be a magnetic structure, or other structure that can be used multiple times. Figure 2 As shown, the connector 200 can connect the two together again, making it easier for the doctor to change the position of the insertion part 100.

[0029] The specific number of the insertion sub-section 110 is determined by the number and arrangement position of the partition surface, and the distance that the partition surface extends toward the proximal end of the insertion section 100 determines the length of the insertion sub-section 110. In some embodiments of the present application, the extension length of the partition surface will not be too long, and along the axial direction of the insertion section 100, the extension distance of the partition surface is less than the length of the insertion section 100. Under such a layout, part of the insertion section 100 can maintain structural integrity, that is, there is an integrally formed part of the insertion section 100 on the side of the handle of the insertion section 100 close to the endoscope, which is conducive to improving the overall characteristics of the insertion section 100 and reducing the difficulty of the insertion section 100 maintaining its overall characteristics during the insertion process. In some preferred embodiments, the insertion section 100 includes an active bending section and a passive bending section, and the partition surface is distributed in the active bending section. The active bending section can be bent under the drive of the traction structure, while the passive bending section maintains structural integrity. Under such a layout, the bending action of the insertion sub-section 110 is not affected, and the insertion section 100 can also maintain structural integrity.

[0030] In the insertion sub-section 110, the specific components are set according to the actual needs of the endoscope. In some embodiments, at least one insertion sub-section 110 is provided with an instrument channel for the instrument to pass through, and / or at least one insertion sub-section 110 is provided with a camera module 300 at the distal end to obtain image information of the lesion location. Figure 6 As shown, and / or, at least one end of the insertion sub-section 110 is provided with a light source assembly for lighting, Figure 6 The camera module 300 in the embodiment can also be replaced with a light source assembly, or Figure 6 An additional light source assembly is also provided next to the camera module 300. The device structure of the insertion sub-section 110 is set according to actual needs and is not specified in this application.

[0031] Since each of the individual insertion sub-sections 110 needs to bend and change under the control of the traction structure, in order to ensure the stability of the overall structure of the insertion sub-section 110, the partition surface is generally set along the axis of the insertion section 100. Under such a layout, the cross-sectional dimensions of the insertion sub-section 110 remain stable in its axial direction, thereby avoiding the situation where the insertion sub-section 110 has a low structural strength and is easy to damage in some sections. In addition, in the case of multiple partition surfaces, the partition surfaces are set along the axis of the insertion section 100, so that the insertion sub-sections 110 separated by the partition surfaces can be arranged around the circumference of the insertion section 100, which is convenient for the insertion sub-section 110 to adjust the bending direction, and at the same time, it is also convenient to control the size of each insertion sub-section 110.

[0032] Along the axis of any insertion sub-section 110, the insertion sub-section 110 includes a circumferential surface 111 and a connecting surface 112 disposed opposite to the adjacent insertion sub-section 110. It can be understood that the circumferential surface 111 is a part of the circumferential surface 111 of the insertion section 100, and the connecting surface 112 is a surface of the insertion sub-section 110 formed after the insertion section 100 is divided by the partition surface, and two adjacent insertion sub-sections 110 are in contact with each other through the connecting surface 112. After the insertion sub-portion 110 reaches the affected area, it can bend and move in the human body driven by the traction structure, and the insertion sub-portion 110 may come into contact with human tissue. In some embodiments of the present application, the connection position between the circumferential surface 111 and the connecting surface 112 of the insertion sub-portion 110 is smoothly transitioned. The smooth transition means that the circumferential surface 111 and the connecting surface 112 are smoothly connected without any protrusions or depressions. The connection position between the two surfaces is smooth without any sharp edges. The insertion sub-portion 110 and the human body structure can avoid causing discomfort to the human body.

[0033] When there are only two insertion sub-parts 110 in the insertion part 100, the insertion sub-part 110 only includes one connecting surface 112. Along the circumference of the insertion sub-part 110, both sides of the connecting surface 112 are connected to the circumferential surface 111 of the insertion sub-part 110. The connection position between the connecting surface 112 and the circumferential surface 111 has a smooth transition to avoid discomfort to the human body during the use of the insertion sub-part 110.

[0034] In the case where the insertion portion 100 has three or more insertion sub-portions 110, since the partition surface is extended along the axis of the insertion portion 100, the three or more insertion sub-portions 110 are arranged along the circumference of the insertion portion 100. Any insertion portion 100 includes a circumferential surface 111 and two connecting surfaces 112 corresponding to the adjacent insertion sub-portions 110. The connection position of the two connecting surfaces 112 also needs to be smoothly transitioned to ensure that the overall structure of the insertion sub-portion 110 has no edges and corners, thereby reducing the discomfort that the insertion sub-portion 110 may cause to the patient.

[0035] In some embodiments, the connecting member 200 is disposed on the surfaces of two adjacent insertion sub-sections 110 that are disposed facing each other. Figures 1 to 3 , Figures 5 to 7 With such a layout, the contact area between two adjacent insertion sub-sections 110 can be increased, and the connection stability can be improved; and, in the case where the connector 200 is a connection structure that can be used multiple times, the connector 200 can smoothly connect the adjacent insertion sub-sections 110 together again after they are attached to each other once; in addition, the connector 200 is located between two adjacent insertion sub-sections 110, and during the process of inserting the insertion section 100 into the human body, the connector 200 will not affect the smoothness of the outer wall of the insertion section 100, and will not affect the insertion action of the insertion section 100.

[0036] The connecting member 200 can be located at any position of two adjacent insertion sub-sections 110, as long as it can connect the two adjacent insertion sub-sections 110. In some preferred embodiments, the connecting member 200 is located at the distal end of the insertion sub-section 110, Figure 5 and Figure 6 The connector 200 connects the distal ends of adjacent insertion sub-sections 110, so that all insertion sub-sections 110 can be connected and combined at the distal ends, thereby making the insertion section 100 have better overall characteristics and facilitating the control of the movement of the insertion section 100 entering the human body.

[0037] In other embodiments, in order to improve the connection stability of adjacent insertion sub-sections 110, the insertion section 100 includes a plurality of connectors 200, which are arranged in sequence from the proximal end to the distal end of the insertion sub-section 110, thereby connecting the adjacent insertion sub-sections 110 from the proximal end to the distal end, so that most of the tube sections of the insertion section 100 have better overall characteristics, which can improve the doctor's control accuracy of the insertion section 100. In addition, among the plurality of connectors 200 between two adjacent insertion sub-sections 110, at least one connector 200 is located at the distal end of the insertion sub-section 110, referring to Figure 7 As shown, the distal end of the insertion portion 100 is ensured to have better overall characteristics and avoid bifurcation at the distal end of the insertion portion 100 during insertion into the human body.

[0038] When the connector 200 has only one connection structure, the connector 200 can be disposed on any one of two adjacent insertion sub-sections 110 . When the connector 200 is divided into two connection structures, two adjacent insertion sub-sections 110 are each provided with a portion of the connector 200 .

[0039] In some preferred embodiments of the present application, the connector 200 may be a magnetic connection structure, and the connector 200 includes two parts, namely, a first connection part 210 and a second connection part 220. The first connection part 210 is installed on one of the two adjacent insertion sub-parts 110, and the second connection part 220 is installed on the other of the two adjacent insertion sub-parts 110. The first connection part 210 and the second connection part 220 are connected by magnetic attraction. As the two adjacent insertion sub-parts 110 approach each other, the gap between the two gradually decreases, and the two are easily reconnected together under the magnetic attraction of the first connection part 210 and the second connection part 220, so that the insertion part 100 can be reassembled into a whole. The magnetic connection structure can be reused, and even after the two insertion sub-parts 110 are separated, the first connection part 210 and the second connection part 220 are exposed to the in vivo environment and tissue fluid contacts the first connection part 210 and the second connection part 220, it will not affect the connection effect of the first connection part 210 and the second connection part 220. Two adjacent insertion sub-parts 110 can be connected and separated multiple times, thereby improving the convenience of doctor's operation.

[0040] In a specific implementation, mounting grooves are provided on the surfaces of two adjacent insertion sub-sections 110 that are arranged facing each other, and the mounting grooves are used to embed the first connection section 210 or the second connection section 220, so that the surface of the first connection section 210 or the surface of the second connection section 220 is flush with the surface of the insertion sub-section 110, thereby avoiding the connector 200 from affecting the flatness of the adjacent insertion sub-sections 110.

[0041] The present application also provides an endoscope, including the insertion portion 100 provided in the above embodiment. The endoscope in the embodiment of the present application can be a bronchoscope, a pyeloscope, an esophagoscope, a gastroscope, an enteroscope, an otoscope, a rhinoscope, a stomatoscope, a laryngoscope, a colposcope, a laparoscope, an arthroscope, etc. The embodiment of the present application does not specifically limit the type of the endoscope.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
