DETAILED DESCRIPTION

[0022] In order to make the purpose, technical scheme and advantages of the present application more clear, the technical scheme of the present application will be described in detail below. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of the present application.

[0023] The terms "first", "second" and the like in the specification and claims of the present application are used to distinguish similar objects, not to describe a particular order or chronological sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second" and the like are generally of a kind, not limited to the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in a "or" relationship.

[0024] In the embodiments of the present application, "proximal end" and "distal end" refer to the relative position of each component to the user in the use environment, wherein the end closer to the user is designated as "proximal end", and the end farther from the user is designated as "distal end".

[0025] The inventive concept of the present application is described as follows:

[0026] An endoscope generally comprises a handle portion and an insertion portion, wherein the insertion portion is a tube equipped with light, which can enter the human body through natural orifices of the human body or through a small incision made by surgery. The insertion portion uses a built-in miniature camera and optical system to transmit images of organs in the body to an external display screen, thereby allowing the physician to visually observe the state of the tissues and organs in the body.

[0027] However, the cross-sectional size of the insertion portion in the prior art is large, and when the natural ducts of the human body are narrow, it is difficult for the operator to control the endoscope to explore in the patient's body. In addition, when the incision needs to be made by surgery to enter the human body, the aforementioned incision also needs to be large, which increases the damage to the patient's body.

[0028] Since the front end seat of the insertion portion is integrated with multiple functional components, and the size of the functional components has generally reached the limit, it is difficult to continue to be small, otherwise it will greatly increase the production cost. Therefore, it is difficult to reduce the size of the functional components and thus reduce the size of the front end seat.

[0029] The inventor found that the space of the side wall of the front end seat is not fully utilized, although the side wall of the front end seat is thin, it still has a certain thickness, and the thickness of the side walls on both sides is still a considerable value on the interface in the axial direction of the front end seat. The current front end seat is mainly used to protect the functional components integrated in the front end seat, and the distal end side of the insertion portion usually needs to be sealed during subsequent processing to prevent body secretions from entering the front end seat. Therefore, the inventor changes the traditional structure of the front end seat and sets a notch on the side wall of the front end seat, which is used to accommodate at least part of the structure of the functional component, so that the side wall of the front end seat can be fully utilized. On the one hand, without changing the size of the front end seat, more space can be left for the functional component, thereby increasing the size of the functional component, thereby facilitating the improvement of the detection accuracy of the endoscope. On the other hand, without changing the size of the functional component, the size of the front end seat can be made smaller, thereby facilitating the entry of the insertion portion into the narrow natural ducts of the human body, and at the same time, the aforementioned incision can also be made smaller when it needs to be made by surgery, thereby facilitating the reduction of damage to the patient's body.

[0030] Based on this, the inventor provides a front end seat, an insertion portion and an endoscope, by setting a notch on the front end seat, without changing the size of the functional component, using the notch to accommodate at least part of the functional component, thereby reducing the size of the front end seat, to at least partially improve the above-mentioned problems.

[0031] The front end seat 20, the insertion portion 2 and the endoscope 1 provided by the utility model will be described in detail below in combination with the accompanying drawings and specific embodiments and application scenarios. Figures 1 to 8 The front end seat 20, the insertion portion 2 and the endoscope 1 provided by the utility model will be described in detail below in combination with the accompanying drawings and specific embodiments and application scenarios.

[0032] Please also refer toFigures 1-3 The utility model embodiment provides an endoscope 1, the endoscope 1 can include handle part 10 and insertion part 2, insertion part 2 can be connected to handle part 10, handle part 10 can be used for operator holds and operates insertion part 2 rotation. Handle part 10 can be provided with instrument mouth 130, instrument mouth 130 can be used for operator inserts detection equipment to insertion part 2 and from insertion part 2's far end stretches out. Insertion part 2 can be used for inserting the natural duct of patient, and the lesion in the natural duct of patient is examined or surgery etc.. The utility model embodiment does not limit the specific connection mode of handle part 10 and insertion part 2, for example can be screw connection, integral molding etc., and can be set according to actual conditions specifically.

[0033] In addition, please refer to Figure 3 The endoscope 1 further includes a first functional piece 110 and a second functional piece 120, the first functional piece 110 and the second functional piece 120 have different functions, for example, providing a light source, capturing a picture, transmitting data, collecting a sample, or performing surgery, etc. The utility model embodiment does not limit the specific form and structure of the first functional piece 110 and the second functional piece 120, for example, in the present embodiment, the first functional piece 110 can be an instrument tube, and the second functional piece 120 can be a camera module. The specific form and structure can be set according to actual conditions.

[0034] Please refer to Figure 1 and Figure 2 again, the insertion part 2 can include an active bending section 4, a passive bending section 5, and a front end seat 20, wherein the passive bending section 5 can be connected to the handle part 10, the active bending section 4 can be connected to one end of the passive bending section 5 away from the handle part 10, and the front end seat 20 can be connected to one end of the active bending section 4 away from the passive bending section 5. The utility model embodiment does not limit the specific connection mode between the active bending section 4, the passive bending section 5, and the front end seat 20, for example, in one embodiment, the active bending section 4, the passive bending section 5, and the front end seat 20 can be set as an integral molding structure, which is conducive to improving the structural stability of the active bending section 4, the passive bending section 5, and the front end seat 20 as a whole, and thus is conducive to reducing the possibility of breakage between the active bending section 4, the passive bending section 5, and the front end seat 20. The specific connection mode can be set according to actual conditions, which is not limited herein.

[0035] Please refer to Figures 3-5The front end seat 20 can be a hollow structure similar to a cylinder, and the front end seat 20 is formed with a mounting cavity 210 which can be used to accommodate the first functional member 110 and the second functional member 120. The front end seat 20 can have opposite first and second end portions 220 and 230, wherein the second end portion 230 is connected with the active bending section 4, and the first end portion 220 is a free end. The first end portion 220 can be provided with a first notch 221 and a second notch 222, and both the first notch 221 and the second notch 222 extend from the first end portion 220 to the second end portion 230. The first notch 221 can be used to accommodate at least part of the first functional member 110, and the second notch 222 can be used to accommodate at least part of the second functional member 120. That is, in the embodiment, after the first functional member 110 and the second functional member 120 are mounted in the mounting cavity 210, at least part of the first functional member 110 and the second functional member 120 are located in the first notch 221 and the second notch 222, so that the space of the side wall of the mounting cavity 210 can be fully utilized, and thus the size of the first end portion 220 can be reduced. The operator can control the endoscope 1 to enter a more narrow natural duct of the patient, and thus the operator can facilitate the examination or surgery of the patient. In addition, when the operator needs to make a surgical incision on the patient's body to send the endoscope 1 into the patient's body, the aforementioned incision can be made smaller, and thus the damage to the patient's body can be reduced.

[0036] Please refer to Figure 6 and Figure 7 In one embodiment, the size of the first notch 221 near the second end portion 230 is smaller than the size of the first notch 221 near the first end portion 220. In another embodiment, the size of the second notch 222 near the second end portion 230 is smaller than the size of the second notch 222 near the first end portion 220. In yet another embodiment, the size of the first notch 221 near the second end portion 230 is smaller than the size of the first notch 221 near the first end portion 220, and the size of the second notch 222 near the second end portion 230 is smaller than the size of the second notch 222 near the first end portion 220. The embodiment of the present application is described by taking the first notch 221 and the second notch 222 as an example, that is, in this embodiment, the first notch 221 and the second notch 222 can be provided with a structure similar to a "V" or a "U". Preferably, the first notch 221 and the second notch 222 can be provided with a structure in which the side wall is inclined and the bottom is smooth. The smooth bottom structure can facilitate the first functional member 110 and the second functional member 120 to respectively extend out of the bottom of the first notch 221 and the second notch 222 and be embedded in the first notch 221 and the second notch 222, so as to avoid or reduce the possibility of damage of the first functional member 110 and the second functional member 120 during installation.

[0037] Further, in some other embodiments, the first functional member 110 and the second functional member 120 can also be integrated into the protective sleeve 30, and the structure of the protective sleeve 30 can be matched with the structure of the front end seat 20, so as to ensure that the protective sleeve 30 can form a sealed environment after being connected to the front end seat 20. Specifically, the protective sleeve 30 can include a first extension 310 and a second extension 320, the first extension 310 can be matched with the first notch 221, and the second extension 320 can be matched with the second notch 222. The structures of the first notch 221 and the second notch 222 can also play a role of pre-positioning, that is, during the process of installing the protective sleeve 30 on the front end seat 20, the first extension 310 can be aligned with the first notch 221, and the second extension 320 can be aligned with the second notch 222, so as to improve the installation efficiency.

[0038] Specifically, in the present embodiment, the front end seat 20 can include a first structure section 240 and a second structure section 250, and the first structure section 240 and the second structure section 250 are connected through a transition surface 280. The first structure section 240 is a region close to the first end 220, and the second structure section 250 is a region close to the second end 230. The first notch 221 and the second notch 222 both extend from the first structure section 240 to the second structure section 250.

[0039] Correspondingly, the first notch 221 and / or the second notch 222 can include a smooth section 270 and an expansion section 260 connected with each other, the smooth section 270 is located in the second structure section 250, and the expansion section 260 is located in the first structure section 240, and the size of the expansion section 260 is larger than that of the smooth section 270. As described above, the expansion section 260 can further play a role of guiding the installation of the protective sleeve 30, and the structure of the front end seat 20 can further improve the efficiency during the installation of the protective sleeve 30. In a more specific embodiment, the size of the expansion section 260 along the axial direction of the front end seat 20 is the same, that is, the extension line of the transition surface 280 and the first structure section 240 can be arranged vertically, which can help to improve the structural strength of the entire front end seat 20. It should be noted that the length of the expansion section 260 should not be set too long, which can also help to avoid or reduce the possibility of breaking the expansion section 260, and thus improve the structural strength of the entire front end seat 20. As described above, in this embodiment, the bottom of the smooth section 270 can be arranged as an arc surface.

[0040] Further, in an embodiment, the junction between the second structural segment 250 and the transition surface 280 is rounded; and / or, the junction between the first structural segment 240 and the end surface of the first end portion 220 is rounded. It can be understood that the end surface of the first end portion 220 and the transition surface 280 can be touched during the installation of the first functional component 110 and the second functional component 120 on the front end seat 20, and thus rounding the above-mentioned positions can avoid or reduce the possibility of damaging the first functional component 110 and the second functional component 120 during the installation on the front end seat 20.

[0041] The utility model embodiment does not limit the specific depth of the first gap 221 and the second gap 222, for example, in an embodiment, the depth of the first gap 221 can be equal to the depth of the second gap 222.

[0042] Please also refer to Figure 4 and Figure 8 It should be noted that the first gap 221 cooperates with the first functional component 110, the second gap 222 cooperates with the second functional component 120, the first functional component 110 is an instrument tube, and the second functional component 120 is a camera module. The instrument tube is a pipeline structure, the proximal end of the instrument tube is in communication with the instrument nozzle 130, the distal end of the instrument tube is integrated on the first end portion 220 of the front end seat 20 and located in the first gap 221, and thus the axis of the instrument tube is not a straight line, and the instrument tube needs to be bent to be arranged in the first gap 221. The distal end side of the camera module has elements such as a lens 122 and a circuit board 123, and the proximal end side of the camera module has a cable 121 for transmitting data, and the size of the cable 121 is usually much smaller than the size of the elements such as the lens 122 and the circuit board 123, and thus the size of the camera module mainly depends on the size of the elements such as the lens 122 and the circuit board 123. The camera module also needs to be bent to be arranged in the second gap 222. In addition, the size of the cable 121 is usually much smaller than the size of the instrument tube, and in the active bending segment 4 and the passive bending segment 5, the instrument tube can compress the space of the cable 121, and bend near the first gap 221 and release the compressed space of the cable 121.

[0043] Therefore, when the depth of the first notch 221 is the same as the depth of the second notch 222, not only the size of the front end seat 20 can be reduced, but also the size of the active bending section 4 and the passive bending section 5 can be reduced. Specifically, since the instrument tube cannot extend out of the installation space, when the instrument tube is bent and arranged in the first notch 221, the instrument tube will be displaced in the radial direction of the insertion part 2, so that the installation cavity 210 needs to have a larger radial space to accommodate the instrument tube, and when the depth of the first notch 221 is the same as the depth of the second notch 222, the radial space in the installation cavity 210 can be reserved by extending the camera module to the second notch 222, so that the bending of the instrument tube can be realized without increasing the size of the active bending section 4 and the passive bending section 5.

[0044] Further, in another embodiment, the depth of the first notch 221 can be set to be greater than the depth of the second notch 222. As described above, since the bending of the instrument tube occurs near the first notch 221, setting the depth of the first notch 221 to be greater than the depth of the second notch 222 can make the bending position of the instrument tube farther away from the first end portion 220 of the installation cavity 210, that is, in this embodiment, the bending positions of the first functional part 110 and the second functional part 120 can be staggered, and the first functional part 110 can be bent at a position farther away from the first end portion 220, avoiding the bending of the first functional part 110 and the second functional part 120 at the same cross section or similar cross section of the front end seat 20, which is beneficial to avoid the collapse of the bending position of the instrument tube, and further can provide good passing performance for the medical instrument subsequently extended from the instrument tube.

[0045] It can be understood that, in a preferred embodiment, the first notch 221 and the second notch 222 can be oppositely arranged, that is, the first notch 221 and the second notch 222 are oppositely arranged in the radial direction of the front end seat 20, which can further utilize the space of the first end face of the front end seat 20, avoid excessive remaining space of the front end seat 20, and further facilitate the miniaturization of the front end seat 20.

[0046] The embodiments of the utility model are not limited to the specific size and specific structure of the first notch 221 and the second notch 222, for example, in an embodiment, the structure of the first notch 221 and the second notch 222 can be set to be consistent, but the size of the first notch 221 can be set to be greater than the size of the second notch 222, which can be set according to actual conditions.

[0047] In summary, the front end seat 20 provided by the embodiment of the utility model, through setting first gap 221 and second gap 222 at the first end 220 of front end seat 20, first gap 221 and second gap 222 can be used for accommodating first functional part 110 and second functional part 120 in insertion part 2 of endoscope 1 respectively, when first functional part 110 and second functional part 120 are installed in installation cavity 210 of front end seat 20, at least part of first functional part 110 is located at first gap 221, and at least part of second functional part 120 is located at second gap 222.That is to say, in the embodiment, the side wall of front end seat 20 is vacant at first gap 221 and second gap 222, and the vacant part can be used for accommodating first functional part 110 and second functional part 120, thereby facilitating the size of the whole front end seat 20 to be small, or, without reducing the size of the whole front end seat 20, the size of first functional part 110 and second functional part 120 can be increased, thereby improving the detection accuracy of the whole endoscope 1, and the like, solving the problem that the cross-sectional size of insertion part 2 is large in the prior art, when the natural pipeline of human body is narrow, it is difficult for the operator to control endoscope 1 to explore in the patient's body, and when the incision is needed to enter the human body, the incision also needs to be enlarged, which will increase the damage to the patient's body.When the above-mentioned front end seat 20 is applied to insertion part 2, insertion part 2 can also solve the above-mentioned problem.When insertion part 2 is applied to endoscope 1, endoscope 1 can also solve the above-mentioned problem.

[0048] It should be noted that in this document, the terms "comprise", "comprising", or any other variant thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements, but can also include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without more limitations, the element defined by the statement "comprises a" does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0049] In addition, it should be noted that the scope of the methods and devices in the embodiments of the utility model is not limited to performing functions in the order shown or discussed, but can also include performing functions in a substantially simultaneous manner or in reverse order according to the functions involved, for example, the described method can be performed in an order different from the described order, and various steps can also be added, omitted, or combined. In addition, the features described with reference to certain examples can be combined in other examples.

[0050] The above merely describes a specific implementation of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
