Abstract

The present invention discloses an insertion part and an endoscope, and relates to the technical field of medical devices. The insertion part includes a tube body, a camera module and an instrument tube. A fixing seat is provided at the distal end of the tube body, and an opening is provided at the fixing seat. The camera module is radially slidably arranged at the opening of the tube body. There is a accommodating space between the fixing seat and the camera module, and the distal end of the instrument tube is located in the accommodating space. The camera module is driven to slide out of the opening by a driving module, and the accommodating space between the camera module and the tube body is increased, and the distal end of the instrument tube has a space for switching from a first state to a second state. For example, when a large-diameter medical device needs to be inserted into the instrument tube for treatment, the distal end of the instrument tube can be stretched open to form a larger passage.

Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and in particular to an insertion portion and an endoscope. Background Art

[0002] During the treatment of a disease, medical staff usually need to use diagnostic instruments of different thicknesses to pass through the instrument tube in the electronic endoscope for diagnosis and treatment. In order to facilitate the endoscope to smoothly enter the human body, the size of the endoscope should not be set too large.

[0003] In addition, a camera module is integrated into the insertion part of the endoscope, which provides visual images to facilitate medical staff to diagnose and treat. However, it also significantly reduces the cross-sectional area of ​​the instrument tube. This greatly limits the possibility of medical devices with larger diameters being inserted smoothly through the instrument tube of the endoscope. Summary of the invention

[0004] In view of the above-mentioned shortcomings of the related art, the present application provides an insertion portion and an endoscope to solve the above-mentioned technical problems.

[0005] The present application provides an insertion portion, comprising a tube body, a camera module and an instrument tube. A fixing seat is provided at the distal end of the tube body, and an opening is formed in the fixing seat. The camera module is slidably arranged at the opening along the radial direction of the tube body. An accommodating space is provided between the fixing seat and the camera module. The distal end of the instrument tube is located in the accommodating space. When the camera module is accommodated in the opening, the instrument tube is in a first state. When the camera module slides out of the opening, the instrument tube can be switched to a second state. The cross-sectional area of ​​the distal end of the instrument tube in the first state is smaller than the cross-sectional area of ​​the distal end of the instrument tube in the second state.

[0006] In one embodiment of the present application, the fixing seat includes a first side plate, a second side plate and a connecting plate connected between the first side plate and the second side plate, the first side plate and the second side plate extend radially along the tube body, an opening is formed between the first side plate and the second side plate, and the connecting plate is arranged opposite to the opening.

[0007] In one embodiment of the present application, limiting portions are provided at opposite ends of the first side plate and / or the second side plate, and the limiting portions are used to limit the movement of the camera module along the axis of the tube body.

[0008] In one embodiment of the present application, the insertion portion further includes a driving module, which is disposed in the accommodating space and is used to drive the camera module to slide radially along the tube body so that the instrument tube switches between the first state and the second state.

[0009] In one embodiment of the present application, the driving module includes an airbag, which is located in the accommodating space. When the airbag is inflated, the airbag drives the camera module to slide along the radial direction of the tube body away from the instrument tube, and / or, when the airbag is inflated, the airbag drives the instrument tube to switch between a first state and a second state.

[0010] In one embodiment of the present application, the airbag includes a first sub-bag and a second sub-bag, and the first sub-bag and the second sub-bag are respectively arranged on both sides of the instrument tube. When the first sub-bag and the second sub-bag are inflated, the first sub-bag and the second sub-bag drive the camera module to slide out of the opening and squeeze the distal end of the instrument tube in a radially inward direction to switch the instrument tube from the first state to the second state.

[0011] In one embodiment of the present application, the airbag includes a first connecting portion and a second connecting portion that are spaced apart, the first connecting portion is connected to a fixing seat, and the second connecting portion is connected to an outer peripheral wall of the instrument tube, and when the distal end of the instrument tube is in a first state, at least one redundant bending portion is formed between the first connecting portion and the second connecting portion.

[0012] In one embodiment of the present application, when the distal end of the instrument tube is in the first state, a first bending portion and a second bending portion are redundantly formed between the first connecting portion and the second connecting portion, and the first bending portion is located on a side of the airbag close to the camera module, and the second bending portion is located on a side of the airbag away from the camera module.

[0013] In one embodiment of the present application, the distal end of the instrument tube is connected between the inner wall of the fixing seat and the camera module, and the instrument tube is switched from the second state to the first state, and the instrument tube drives the camera module so that the camera module is accommodated in the opening.

[0014] In one embodiment of the present application, the insertion portion further includes an elastic member, which is used to drive the camera module to be accommodated in the opening and drives the camera module to be accommodated in the opening.

[0015] In one embodiment of the present application, the insertion part also includes an elastic skin, which covers the outside of the tube body and is provided with a first through hole and a second through hole. The first through hole is arranged opposite to the camera module, and the second through hole is connected to the instrument tube. The elastic skin closes the opening, and the elastic skin is used to drive the camera module so that the camera module is accommodated in the opening, and the instrument tube is switched from the second state to the first state.

[0016] In one embodiment of the present application, the camera module includes a camera seat, a light source and a camera. The camera seat is slidably disposed at the opening along the radial direction of the tube body, and the light source and the camera are disposed in the camera seat.

[0017] To achieve the above-mentioned purpose and other related purposes, the present application provides an endoscope, including the aforementioned insertion portion.

[0018] The technical solution adopted by the present invention can achieve the following beneficial effects: the tube body can be adapted to the internal tissue of the human body, so that the insertion part can be smoothly inserted into the human body. The camera module can clearly obtain the image information before the insertion part, so that medical staff can observe the condition and control the bending and insertion of the insertion part. The camera module is driven to slide out of the opening by the driving module, and the accommodation space between the camera module and the tube body is increased, and the distal end of the instrument tube has a space for switching from the first state to the second state. For example, when a large-diameter medical device needs to be inserted into the instrument tube for treatment, the camera module is driven to slide out of the opening by the driving module, so that the distal part of the instrument tube can be stretched to form a larger channel. Exemplarily, the distal end of the instrument tube can be actively switched or passively switched from an ellipse to a circle, and its cross-sectional area is significantly improved. In addition, when the distal end of the instrument tube is switched to the second state, the bending caused by the extrusion of the distal end of the instrument tube is eliminated to avoid affecting the entry of the diagnostic and treatment equipment. This arrangement does not affect the insertion of the insertion portion into the human body, and can also increase the cross-sectional area of ​​the instrument tube, so that medical devices with larger diameters can be smoothly inserted into the instrument tube of the insertion portion, thereby increasing the scope of application.

DETAILED DESCRIPTION

[0030] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[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] In each embodiment of the present application, "proximal end" and "distal end" refer to the position of each component 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".

[0033] During the treatment of a disease, medical staff usually need to use diagnostic instruments of different thicknesses to pass through the instrument tube in the electronic endoscope for diagnosis and treatment. In order to facilitate the endoscope to smoothly enter the human body, the size of the endoscope should not be set too large.

[0034] In addition, a camera module is integrated into the insertion part of the endoscope, which provides visual images to facilitate medical staff to diagnose and treat. However, it also significantly reduces the cross-sectional area of ​​the instrument tube. This greatly limits the possibility of medical devices with larger diameters being inserted smoothly through the instrument tube of the endoscope.

[0035] This embodiment provides an insertion portion 100, see Figure 1 The insertion portion 100 is used to be inserted into a natural orifice of the human body or enter the human body through a surgical incision, so that medical personnel can observe or access areas that are difficult to reach with traditional examination methods. Figure 1 The outer surface of the inserting part 100 is not shown to facilitate observation of its internal structure. The inserting part 100 may include a tube body 110, a camera module 120 and an instrument tube 130. The camera module 120 is slidably disposed on the tube body 110, and the instrument tube 130 is disposed inside the tube body 110.

[0036] In this example, please continue to refer to Figure 1 The tube body 110 may be an elongated hollow tubular structure, which is not limited in the present embodiment, and the tube body 110 may be a rigid tube or a flexible tube, etc., which may be selected and designed according to specific application scenarios. A fixing seat 111 is provided at the distal end of the tube body 110, and the fixing seat 111 may be integrated with the tube body 110 or may be detachably provided. The fixing seat 111 may have a certain strength, which may prevent the end of the insertion portion 100 from being damaged during the insertion process, and may provide an installation foundation and support for the instrument tube 130. The fixing seat 111 is provided with an opening 112, and the opening 112 may be adapted to the outer contour of the camera module 120, so that the camera module 120 may slide smoothly into or out of the tube body 110.

[0037] For more information, please refer to Figure 1 as well as Figure 2The fixing seat 111 may include a first side plate 113, a second side plate 114 and a connecting plate 115, and the connecting plate 115 is connected between the first side plate 113 and the second side plate 114. Among them, the first side plate 113, the second side plate 114 and the connecting plate 115 can be integrated to improve the structural strength of the fixing seat 111. The first side plate 113 and the second side plate 114 extend along the radial direction of the tube body 110, the opening 112 is formed between the first side plate 113 and the second side plate 114, and the connecting plate 115 is arranged opposite to the opening 112. The shape and size of the opening 112 will be determined according to actual needs to ensure that it can be adapted to the camera module 120. In addition, the first side plate 113 and the second side plate 114 can be respectively abutted against the two sides of the camera module 120, thereby limiting the direction of sliding in or out of the camera module 120, and ensuring the stable operation of the camera module 120.

[0038] Preferably, see Figure 2 , the first side plate 113 and / or the second side plate 114 are provided with limiting parts at opposite ends, and the limiting parts are used to limit the movement of the camera module 120 along the axis of the tube body 110, and the limiting parts are used to limit the unnecessary movement or displacement of the camera module 120 along the axis direction of the tube body 110. Exemplarily, the first side plate 113 and the second side plate 114 are provided with limiting parts at opposite ends, and the limiting parts may include a first limiting part 116 and a second limiting part 117, the first limiting part 116 of the first side plate 113 is formed by the end of the first side plate 113 being bent toward the side close to the second side plate 114, the first limiting part 116 of the second side plate 114 is formed by the end of the second side plate 114 being bent toward the side close to the first side plate 113, and the second limiting part 117 may be connected between the first limiting part 116 and the second limiting part 117. The first stopper 116 and the second stopper 117 can abut against the camera module 120 to prevent the camera module 120 from sliding out of the tube body 110 along the axis of the tube body 110 and causing the camera module 120 to fall. The design of the stopper ensures that the camera module 120 can remain stable when subjected to external forces (such as vibration, impact, etc.) and will not move unexpectedly along the axis of the tube body 110.

[0039] It is understandable that the limiting portion can also be a buckle, a bolt hole or a limiting rod, etc., which can be selected and designed according to the specific camera module 120.

[0040] In this example, see Figure 3, the camera module 120 can obtain the image signal inside the human body and transmit the image signal. The camera module 120 is set at the opening 112 along the radial sliding of the tube body 110. In other words, the camera module 120 can move on a plane perpendicular to the axis of the tube body 110, so as to adjust its position relative to the opening 112 of the tube body 110. In addition, the first side plate 113, the second side plate 114 and the limiting part have a limiting effect on the camera module 120, so that the camera module 120 can move smoothly and accurately along the predetermined path. There is a accommodating space 118 between the fixing seat 111 and the camera module 120, and the accommodating space 118 can change with the movement of the camera module 120. Exemplarily, the camera module 120 slides outward along the radial direction of the tube body 110, and the accommodating space 118 gradually increases, and the camera module 120 slides inward along the radial direction of the tube body 110, and the accommodating space 118 gradually decreases. The cross-sectional area of ​​the accommodating space 118 can be variably set, which can improve the application prospect of the insertion part 100.

[0041] For more details, please refer to Figure 3 The camera module 120 may include a camera seat 121, a light source 122, and a camera 123. The camera seat 121 is slidably disposed at the opening 112 along the radial direction of the tube body 110, and the light source 122 and the camera 123 are disposed in the camera seat 121. Figure 4 As shown, Figure 4 The outer surface of the inserting part 100 is not shown, so as to facilitate observation of its internal structure. The camera seat 121 can be configured to be able to move along the radial direction of the tube body 110 (such as Figure 4 The camera holder 121 and the light source 122 can be oriented to the camera 123 and the light source 123 to facilitate adjustment and positioning of the camera holder 121 and the light source 122. The camera holder 121 can provide a certain protection effect for the light source 122 and the camera 123, thereby improving the protection capability of the camera module 120. The camera 123 can obtain image signals from inside the human body and transmit the image signals. The light source 122 can be an LED light source, etc., and the light source 122 can provide necessary lighting for the camera 123. In addition, the orientation of the camera 123 and the light source 122 can be perpendicular to the movement direction of the camera holder 121, that is, the orientation of the camera 123 and the light source 122 is always in one direction, so as to facilitate medical staff to operate the insertion part 100.

[0042] In this example, see Figure 3 The instrument tube 130 can provide a passage for passing the diagnostic and treatment instruments to facilitate medical personnel to treat the inside of the human body. The distal end of the instrument tube 130 is located in the accommodating space 118, and the tube body 110 can protect the instrument tube 130 and improve the protection capability of the instrument tube 130.

[0043] like Figure 3As shown, when the camera module 120 is accommodated in the opening 112, the instrument tube 130 is in the first state. Since the distal end of the instrument tube 130 is confined in the accommodation space 118, its cross-sectional area is relatively small. This arrangement can help maintain the compactness and stability of the insertion portion 100 as a whole, making it convenient for medical personnel to operate the insertion portion 100 to insert into the human body.

[0044] like Figure 5 As shown, when the camera module 120 slides out of the opening 112, the sliding direction of the camera module 120 is as follows: Figure 5 As shown in L1 in FIG. 1 , the instrument tube 130 can be switched to the second state, and the cross-sectional area of ​​the distal end of the instrument tube 130 in the first state is smaller than the cross-sectional area of ​​the distal end of the instrument tube 130 in the second state. The distal end of the instrument tube 130 is no longer restricted by the accommodation space 118, and its cross-sectional area will increase accordingly. This change not only provides a larger operating space and field of view for the camera module 120, but also enables the instrument tube 130 itself to be more flexibly inserted into diagnostic and treatment instruments of different sizes. Also, please refer to Figure 6 as well as Figure 7 , Figure 6 is a cross-sectional view of the insertion portion 100 when the instrument tube 130 is in the first state, Figure 7 It is a cross-sectional view of the insertion part 100 when the instrument tube 130 is in the second state. In contrast, it can be seen that the outer diameter of the insertion part 100 is smaller when the instrument tube 130 is in the first state, which is more convenient for insertion into the human body. In addition, when the distal end of the instrument tube 130 is switched to the second state, the bending caused by the distal end of the instrument tube 130 being squeezed is eliminated to avoid affecting the entry of the diagnostic and treatment equipment. This setting can ensure that the switching of the instrument tube 130 between different states is both smooth and reliable. It also improves the practicality and flexibility of the insertion part 100.

[0045] It is understandable that in one embodiment, after the insertion portion 100 is inserted into the designated position, no other device is required to drive the camera module 120 and the instrument tube 130. Medical personnel can directly insert the diagnostic and treatment instrument into the instrument tube 130, and the diagnostic and treatment instrument can drive the distal end of the instrument tube 130 to switch to the second state, for example, from an elliptical shape to a circular shape, and at the same time drive the camera module 120 to slide out of the opening 112.

[0046] In this example, please refer to Figure 1The insertion part 100 may further include a driving module 140, which is disposed in the accommodating space 118 and is used to drive the camera module 120 to slide radially along the tube body 110, so that the instrument tube 130 switches between the first state and the second state. The driving module 140 can actively change the relative position of the camera module 120 and synchronously switch the state of the instrument tube 130. This arrangement can provide sufficient space for the diagnostic and treatment instruments, ensure that the diagnostic and treatment instruments can be smoothly inserted, and effectively improve the use effect of the insertion part 100.

[0047] Please review Figure 3 , the driving module 140 may include an airbag 141, and the airbag 141 is located in the accommodating space 118. Furthermore, an airflow channel (not shown) may be provided in the tube body 110, and the airflow channel may be connected to the airbag 141 and an air pump, etc., and the air pump may be used to control the inflation and deflation of the airbag 141. When the airbag 141 is inflated, the airbag 141 drives the camera module 120 to slide in the radial direction of the tube body 110 away from the instrument tube 130, and / or, when the airbag 141 is inflated, the airbag 141 drives the instrument tube 130 to switch between the first state and the second state. The airbag 141 can effectively drive the camera module 120 and / or the instrument tube 130 to ensure that the diagnostic and treatment equipment can be smoothly inserted, and effectively improve the use effect of the insertion part 100. The driving effect of the airbag 141 is smoother and more efficient, which is convenient for medical staff to operate.

[0048] In one embodiment, the airbag 141 can push the camera module 120 to slide, so that the camera module 120 slides out of the opening 112, increasing the volume of the accommodating space 118, and providing a certain space for the distal end of the instrument tube 130 to switch to the second state. The instrument tube 130 can automatically return to the second state or passively switch to the second state by inserting a diagnostic instrument.

[0049] In another embodiment, the airbag 141 can push the instrument tube 130 to switch the instrument tube 130 between the first state and the second state. The instrument tube 130 pushes the camera module 120 to move during the state switching process, so that the camera module 120 slides into or out of the opening 112.

[0050] In another embodiment, the airbag 141 can drive the camera module 120 and the instrument tube 130 at the same time. This setting can greatly improve the driving effect of the driving module 140, ensure the insertion efficiency of the diagnostic and treatment equipment, and effectively improve the use effect of the insertion part 100.

[0051] In this example, please continue to refer to Figure 3The airbag 141 may include a first subbag 142 and a second subbag 143, and the first subbag 142 and the second subbag 143 are respectively arranged on both sides of the instrument tube 130. Exemplarily, when the first subbag 142 and the second subbag 143 are inflated, the first subbag 142 and the second subbag 143 drive the camera module 120 to slide out of the opening 112, and squeeze the distal end of the instrument tube 130 in the radially inward direction, so that the instrument tube 130 switches from the first state to the second state. The first subbag 142 and the second subbag 143 can squeeze both sides of the instrument tube 130, and a larger number of airbags 141 can apply the squeezing force more evenly to the instrument tube 130, which effectively avoids the stress concentration of the instrument tube 130 and ensures the safety of the instrument tube 130.

[0052] In some other cases, the airbag 141 may further include more sub-bags, such as a third sub-bag, a fourth sub-bag, etc., and the driving force of the airbag 141 may be more evenly transmitted to the camera module 120 and / or the instrument tube 130 .

[0053] In this example, please continue to refer to Figure 4 The airbag 141 may include a first connection portion 144 and a second connection portion 145, the first connection portion 144 and the second connection portion 145 are arranged at intervals, the first connection portion 144 is connected to the fixing seat 111, and the second connection portion 145 is connected to the outer peripheral wall of the instrument tube 130. When the distal end of the instrument tube 130 is in the first state, at least one redundant bending portion is formed between the first connection portion 144 and the second connection portion 145. The redundant bending portion allows the first connection portion 144 and the second connection portion 145 to move relative to each other. The bending portion is deformed when the airbag 141 is inflated, so that the first connection portion 144 and the second connection portion 145 can move in opposite directions. The airbag 141 squeezes the outer peripheral wall of the instrument tube 130, so that the instrument tube 130 switches from the first state to the second state, ensuring that the diagnostic and treatment instruments can smoothly enter the instrument tube 130. At the same time, during the inflation of the airbag 141, the bending portion can move toward the camera module 120 to drive the camera module 120 to slide out of the opening 112, ensuring that the instrument tube 130 can be smoothly switched to the second state.

[0054] For more details, please refer to Figure 3When the distal end of the instrument tube 130 is in the first state, a first bending portion 146 and a second bending portion 147 are redundantly formed between the first connecting portion 144 and the second connecting portion 145. The first bending portion 146 is located on the side of the airbag 141 close to the camera module 120, and the second bending portion 147 is located on the side of the airbag 141 away from the camera module 120. The first bending portion 146 and the second bending portion 147 are located on both sides of the line between the first connecting portion 144 and the second connecting portion 145. The first bending portion 146 and the second bending portion 147 are deformed when the airbag 141 is inflated, so that the first connecting portion 144 and the second connecting portion 145 can move in opposite directions, so that the instrument tube 130 is switched from the first state to the second state, and the use effect of the airbag 141 is ensured. At the same time, when the airbag 141 is inflated, the first bending portion 146 and the second bending portion 147 can bulge outward to increase the distance between the camera module 120 and the fixing seat 111, drive the camera module 120 to slide out of the opening 112, and provide sufficient space for the instrument tube 130 to smoothly switch to the second state.

[0055] It is understandable that the airbag 141 may include a plurality of sub-bags, and each sub-bag may include a first connecting portion 144 and a second connecting portion 145. The first connecting portion 144 and the second connecting portion 145 of each sub-bag may also form at least one redundant bending portion, and further, each sub-bag may also redundantly form a first bending portion 146 and a second bending portion 147, so as to improve the driving effect of each sub-bag on the camera module 120 and the instrument tube 130, which will not be described in detail here.

[0056] In this example, see Figure 3 , the camera module 120 is driven to slide back into the fixing seat 111 through other devices, ensuring that the camera module 120 can be accurately returned to its position, avoiding the camera module 120 from obstructing medical staff from removing the insertion part 100, and improving the safety of the camera module 120.

[0057] In one embodiment, please refer to Figure 3 The distal end of the instrument tube 130 is connected between the inner wall of the fixing seat 111 and the camera module 120, and the instrument tube 130 is switched from the second state to the first state, and the instrument tube 130 drives the camera module 120 so that the camera module 120 is accommodated in the opening 112. Exemplarily, the inner wall of the fixing seat 111 and the camera module 120 are bonded to the opposite sides of the instrument tube 130, and the instrument tube 130 is driven by the airbag 141 to switch to the first state, and the instrument tube 130 drives the camera module 120 to slide toward the inner wall of the fixing seat 111, so that the camera module 120 slides back into the fixing seat 111, ensuring that the camera module 120 can be driven to return accurately.

[0058] In another embodiment, the inserting portion 100 may further include an elastic member (not shown), which may be a spring or a spring sheet, etc., and this embodiment is not limited thereto. The elastic member is used to drive the camera module 120 to be accommodated in the opening 112 and drive the camera module 120. The elastic member may automatically drive the camera module 120 to slide back into the fixing seat 111, thereby improving work efficiency and safety.

[0059] In another embodiment, see Figure 8 The insertion part 100 further includes an elastic skin 150, which covers the outside of the tube body 110, and the elastic skin 150 is provided with a first through hole 151 and a second through hole 152, wherein the first through hole 151 is arranged opposite to the camera module 120, and the second through hole 152 is connected to the instrument tube 130, and the elastic skin 150 closes the opening 112. The elastic skin 150 can effectively improve the protection capability of the insertion part 100, prevent the body fluid of the human body from entering the camera module 120, etc., and ensure that the insertion part 100 can work smoothly. At the same time, the elastic skin 150 has a certain elasticity and buffering capacity, which prevents the insertion part 100 from damaging human tissues when inserted, and improves the safety of the insertion part 100. In addition, the elastic skin 150 can also surround and connect to the distal end of the instrument tube 130, avoid the appearance of a gap between the instrument tube 130 and the elastic skin 150, and further improve the safety of the insertion part 100.

[0060] In addition, the elastic skin 150 can also be used to drive the camera module 120 so that the camera module 120 is accommodated in the opening 112, and the instrument tube 130 is switched from the second state to the first state. Moreover, when the instrument tube 130 switches the state, the elastic skin 150 always covers the end of the instrument tube 130, and the second through hole 152 is always arranged corresponding to the instrument tube 130, so as to improve the protection performance of the instrument tube 130. When the camera module 120 slides out of the opening 112, the elastic skin 150 is deformed, and the deformed elastic skin 150 drives the camera module 120 to slide back into the opening 112, so that the camera module 120 slides back into the fixing seat 111, ensuring that the camera module 120 can be accurately returned to its position. Moreover, the camera module 120 is driven and synchronously squeezes the instrument tube 130, so that the instrument tube 130 switches from the second state to the first state. This configuration can cause the airbag 141 to deflate, the instrument tube 130 to automatically switch back to the first state, and the camera module 120 to slide back into the fixing seat 111, thereby improving work efficiency and safety.

[0061] To achieve the above-mentioned and other related purposes, the present application provides an endoscope 1, see Fig. 9 , the endoscope 1 includes the aforementioned insertion portion 100 .

[0062] The present embodiment provides an insertion portion 100 and an endoscope 1, wherein the tube body 110 can be adapted to the internal tissue of the human body, so that the insertion portion 100 can be smoothly inserted into the human body. The camera module 120 can clearly obtain the image information before the insertion portion 100, so that the medical staff can observe the condition and control the bending and insertion of the insertion portion 100. The camera module 120 is driven to slide out of the opening 112 by the driving module 140, and the accommodation space 118 between the camera module 120 and the tube body 110 is increased, and the distal end of the instrument tube 130 has a space for switching from the first state to the second state. For example, when a large-diameter medical device needs to be inserted into the instrument tube 130 for treatment, the camera module 120 is driven to slide out of the opening 112 by the driving module 140, so that the distal end of the instrument tube 130 can be opened to form a larger channel. Exemplarily, the distal end of the instrument tube 130 can be actively switched or passively switched from an ellipse to a circle, and its cross-sectional area is significantly improved. Furthermore, when the distal end of the instrument tube 130 is switched to the second state, the bending caused by the squeezing of the distal end of the instrument tube 130 is eliminated, so as to avoid affecting the entry of the diagnostic and treatment instruments. This setting does not affect the insertion of the insertion part 100 into the human body, and can also increase the cross-sectional area of ​​the instrument tube 130, so that medical instruments with larger diameters can be smoothly inserted into the instrument tube 130 of the insertion part 100, thereby increasing the scope of application.
