Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an electrically controlled endoscope. Background Art

[0002] As an important medical diagnostic and treatment device, electronic endoscopes typically include a water and gas pipeline system for water injection, gas injection, and suction, as well as a light guide component for image transmission. During clinical use, electronic endoscopes frequently come into contact with patient fluids and tissues, making thorough postoperative cleaning and disinfection (decontamination) crucial to preventing cross-infection.

[0003] However, due to the large size and complex internal structure of electronically controlled endoscopes (such as optical channels and water and gas supply lines), it is difficult to completely remove contaminants from corners during the decontamination process. This is especially true at the connection between the light guide plug and the insertion part, where dirt easily remains, significantly increasing the risk of cross-infection. Furthermore, the water and gas lines in existing devices are thin in diameter, long in length, and contain multiple connectors. This structure not only hinders the full flow and flushing of the decontamination solution, but also creates hidden areas at bends in the pipes or gaps in the joints that are difficult to clean, further exacerbating the problem of decontamination residue. Summary of the Invention

[0004] The present invention provides an electric-controlled endoscope to solve the defect in the prior art that endoscopes are prone to disinfection residues. By separating the water-vapor plug and the photoelectric plug from the scope body, the manufacturing cost of the water-vapor plug is low, and the water-vapor plug as a whole can be used as a disposable consumable. Only the insertion part and the bending part of the electric-controlled endoscope can be disinfected, thereby effectively shortening the length of the electric-controlled endoscope that needs to be disinfected, and effectively reducing the risk of disinfection residues and the disinfection workload.

[0005] The electronically controlled endoscope provided by the present invention comprises: A mirror body, wherein an operating portion of the mirror body is provided with a first photoelectric communication interface and a water-gas interface; The water-gas plug comprises a connecting seat and a water-gas conduit, wherein the water-gas conduit is connected to one end of the connecting seat, and the other end of the connecting seat is used for detachable connection with the water-gas interface; The optoelectronic plug includes a data plug, a transmission line and a light guide plug. The data plug and the light guide plug are respectively arranged at both ends of the transmission line. The data plug is used to be detachably connected to the first optoelectronic communication interface, and the light guide plug is used to connect to the display device.

[0006] According to the electric-controlled endoscope provided by the present invention, the scope body further comprises a clamp channel seat, which is provided at the end of the operating portion away from the insertion portion of the scope body and protrudes from the shell surface of the operating portion; The clamp channel seat includes an integrally formed clamp channel interface and a suction interface, and the suction interface and the clamp channel interface are connected to each other at an angle.

[0007] According to the electrically controlled endoscope provided by the present invention, the axis of the clamp channel interface is collinear with the axis of the insertion portion of the scope body.

[0008] According to the electrically controlled endoscope provided by the present invention, the first photoelectric communication interface is provided at the end of the operating portion away from the insertion portion of the scope body.

[0009] According to the electrically controlled endoscope provided by the present invention, the data plug comprises: Plug housing; a second optoelectronic communication interface, provided at an end of the plug housing and connected to the transmission line, the second optoelectronic communication interface being configured to connect to the first optoelectronic communication interface; A fixing assembly is provided on the plug housing, and is used to connect the plug housing with the operating portion.

[0010] According to the electrically controlled endoscope provided by the present invention, the fixing assembly includes a hook, a paddle, and a first elastic member. The hook is rotatably provided on the plug housing, and the paddle is connected to the hook, and the paddle is used to drive the hook to rotate; one end of the first elastic member is connected to the hook or the paddle, and the other end is connected to the plug housing, and the first elastic member is used to limit the rotation of the hook; The end of the operating portion is provided with a photoelectric socket matching the hook. When the plug housing is connected to the operating portion, the hook is used to extend into the photoelectric socket and hook onto the side wall of the photoelectric socket.

[0011] According to the electrically controlled endoscope provided by the present invention, the connecting seat includes: A water-gas pipe seat, one end of which is provided with a locking element and a pipe joint, wherein the locking element is used to connect to the water-gas jack of the water-gas interface; the pipe joint is connected to the water-gas conduit, and the pipe joint is used to connect to the water-gas pipe of the water-gas interface; A push-pull shell is sleeved on the outer sides of the water and gas pipe seat and the water and gas pipe; A backstop assembly is sleeved on the outside of the water and gas conduit and can slide back and forth along the inner cavity of the push-pull shell. The backstop assembly is provided with a pin at one end facing the water and gas pipe seat; when the locking element is connected to the water and gas socket, the backstop assembly abuts against the push-pull shell, and the pin is passed through the interior of the locking element to limit the relative position of the locking element and the water and gas socket.

[0012] According to the electrically controlled endoscope provided by the present invention, the push-pull shell is provided with an observation window, and the end of the anti-retraction component facing the water and gas pipe seat is provided with a first identification piece, and the first identification piece matches the position of the observation window.

[0013] According to the electrically controlled endoscope provided by the present invention, a second identification member is provided at one end of the anti-retraction component facing the water and gas pipe seat, and the second identification member is located at an end of the first identification member away from the water and gas pipe seat.

[0014] According to the electric-controlled endoscope provided by the present invention, the surface of the water and gas pipe seat is provided with a first rib and a second rib, and the first rib is provided on a side of the second rib facing the locking element; The inner wall of the push-pull shell is provided with a first hook corresponding to the position of the first rib, and the backstop assembly is provided with a second hook corresponding to the position of the second rib; when the locking element is connected to the water and gas socket, the distance between the first rib and the first hook is equal to the distance between the second rib and the second hook.

[0015] In the electric-controlled endoscope provided by the present invention, the water-vapor plug and the photoelectric plug are separated from the mirror body, and the manufacturing cost of the water-vapor plug is low. In this way, during the use of the electric-controlled endoscope, the water-vapor plug as a whole can be used as a disposable consumable. During the disinfection process of the electric-controlled endoscope, only the insertion part and the bending part of the electric-controlled endoscope can be disinfected, thereby effectively shortening the length of the electric-controlled endoscope that needs to be disinfected, and effectively reducing the risk of disinfection residues and the disinfection workload.

[0016] Compared with the prior art, in the electric-controlled endoscope provided by the present invention, this split design can reduce the structure of the electric-controlled endoscope that requires frequent disinfection, and since the water-gas plug as a whole can be used as a disposable consumable, the special structure of the water-gas plug in the prior art (such as the water-gas pipeline with a thin diameter, a long length and multiple connecting joints, and the bends or joint gaps forming hidden areas that are difficult to clean) can be avoided. The burden on the disinfection process and the problems of disinfection residues are avoided; in addition, since the photoelectric plug and the mirror body can be separated, and the insertion part and the bending part of the mirror body can be disinfected separately, there are no dead corners that are difficult to clean during the disinfection process (such as the connection between the photoelectric plug and the water-gas plug and the mirror body); for medical institutions, the above-mentioned setting can effectively reduce operation and maintenance costs; for patients, it can effectively reduce the risk of cross infection caused by incomplete disinfection. In other words, the safety of the electric-controlled endoscope is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] See Figures 1 to 3An embodiment of the present invention provides an electrically controlled endoscope, which includes a scope body 100, a water vapor plug 300, and a photoelectric plug 400; wherein, the scope body 100 includes an insertion portion 110, an operating portion 200, and a bending portion 120, the operating portion 200 is arranged at one end of the insertion portion 110, and the bending portion 120 is arranged at the other end of the insertion portion 110, and the pipeline layout in the operating portion 200 can adopt a hose structure. The specific structures of the insertion portion 110, the operating portion 200, and the bending portion 120 can refer to the existing technology.

[0050] Figure 4 is a schematic diagram of the axial structure of the operating portion provided by an embodiment of the present invention at a first viewing angle; Figure 5 3 is a schematic diagram of the axial structure of the operating portion provided by an embodiment of the present invention at a second viewing angle.

[0051] See Figure 4 and Figure 5 In an embodiment of the present invention, the operating portion 200 includes an end seat 230, a water-gas interface 250, a first photoelectric communication interface 260, a handle housing 211, and a tapered sleeve 220. The end seat 230, the handle housing 211, the tapered sleeve 220, and the insertion portion 110 are connected in sequence. The water-gas interface 250 and the first photoelectric communication interface 260 are both arranged on the top of the end seat 230. In some optional embodiments, the water-gas interface 250 and the first photoelectric communication interface 260 can also be arranged on the side of the end seat 230 or the handle housing 211, and can be adaptively arranged according to actual conditions. Among them, the water-gas interface 250 includes a water-gas jack 251 and a water-gas pipe 252, which are used to detachably connect the water-gas plug 300.

[0052] Figure 6 This is a schematic diagram of the assembly structure of the operating unit and the photoelectric plug provided by an embodiment of the present invention; Figure 7 yes Figure 6 Schematic diagram of the corresponding cross-section structure.

[0053] See Figures 4 to 7 The end seat 230 also includes a photoelectric jack 262, and the operating part 200 also includes a first light guide 261. The first light guide 261 is sequentially arranged through the bending part 120, the insertion part 110, the tapered sleeve 220, the handle shell 211 and the end seat 230. One end of the first light guide 261 is used to connect to the camera device of the bending part 120, and the other end is connected to the first photoelectric communication interface 260. The first photoelectric communication interface 260 is provided with multiple electrical connection points.

[0054] Figure 8 This is a schematic diagram of the axial structure of a water-gas plug provided by an embodiment of the present invention in one situation; Figure 9 yes Figure 8 Schematic diagram of the corresponding explosion structure; Figure 10It is a schematic diagram of the axial structure of the optoelectronic plug provided by an embodiment of the present invention.

[0055] See Figure 8 and Figure 9 The water-gas plug 300 includes a connection base 310 and a water-gas conduit 350. The water-gas conduit 350 is connected to one end of the connection base 310. As mentioned above, the other end of the connection base 310 is used for detachable connection with the water-gas jack 251 and the water-gas conduit 252 in the water-gas interface 250. Figure 6 and Figure 10 In an embodiment of the present invention, the optoelectronic plug 400 includes a data plug 410, a transmission line 420 and a light guide plug 430. The data plug 410 is arranged at one end of the transmission line 420, and the light guide plug 430 is arranged at the other end of the transmission line 420. The light guide plug 430 is used to connect to an external display device, such as a display screen. The specific structures of the data plug 410, the transmission line 420 and the light guide plug 430 can refer to the existing technology. What the embodiment of the present invention wants to highlight is that the data plug 410 is directly used for detachable connection with the first optoelectronic communication interface 260 on the surface of the mirror body 100.

[0056] See Figures 1 to 10 It can be understood that, in the electric-controlled endoscope provided in the embodiment of the present invention, the water-vapor plug 300 and the photoelectric plug 400 are separated from the mirror body 100, so the manufacturing cost of the water-vapor plug 300 is low. In this way, during the use of the electric-controlled endoscope, the water-vapor plug 300 can be used as a disposable consumable material. During the disinfection process of the electric-controlled endoscope, only the insertion part 110 and the bending part 120 of the electric-controlled endoscope can be disinfected, thereby effectively shortening the length of the electric-controlled endoscope that needs to be disinfected, and effectively reducing the risk of disinfection residue and the disinfection workload.

[0057] Compared with the prior art, the split design of the electronically controlled endoscope provided in the embodiment of the present invention can reduce the need for frequent disinfection of the electronically controlled endoscope. Moreover, since the water-gas plug 300 as a whole can be used as a disposable consumable, the burden on the disinfection process and the problem of disinfection residue caused by the special structure of the water-gas plug 300 in the prior art (such as the water-gas pipeline having a thin diameter, a long length, and multiple connecting joints, and bends or joint gaps forming hidden areas that are difficult to clean) can be avoided. In addition, since the optoelectronic plug 400 and the scope body 100 can be separated and the insertion portion 110 and the curved portion 120 of the scope body 100 can be disinfected separately, there are no hard-to-clean dead corners (such as the connection between the optoelectronic plug 400 and the water-gas plug 300 and the scope body 100) during the disinfection process. For medical institutions, the above arrangement can effectively reduce operation and maintenance costs. For patients, it can effectively reduce the risk of cross infection caused by incomplete disinfection. In other words, it improves the safety of the electronically controlled endoscope.

[0058] Continue reading Figure 4 In an optional embodiment of the present invention, the end seat 230 includes a first end face 231, a second end face 232 and a connecting face 233. The connecting face 233 is arranged between the first end face 231 and the second end face 232, and the first end face 231 and the second end face 232 are arranged in parallel. In other words, the first end face 231, the second end face 232 and the connecting face 233 are arranged in a stepped shape.

[0059] Continue reading Figure 4 、 Figure 5 and Figure 6 In an optional embodiment of the present invention, the insertion portion 110 further includes a clamp channel seat 240, which is arranged on the first end surface 231 of the end seat 230. The clamp channel seat 240 includes an integrally formed clamp channel interface 241 and a suction interface 242. The clamp channel interface 241 and the suction interface 242 are arranged at an angle to each other, and the internal holes of the suction interface 242 are connected to the internal holes of the clamp channel interface 241. The clamp channel interface 241 is the surgical instrument channel of the electric-controlled endoscope, and the suction interface 242 is the water vapor suction channel of the electric-controlled endoscope. In this embodiment of the present invention, the clamp channel seat 240 is protruded as a whole on the first end surface 231. In other words, the clamp channel seat 240 is externally placed on the top of the end seat 230.

[0060] In the prior art, the channel clamp seat 240 uses a built-in tee, which is a certain distance away from the first end face 231 of the end seat 230. Generally, it is necessary to connect the built-in tee with the opening on the first end face 231 of the end seat 230 by welding multiple stainless steel pipes. However, such a setting will cause the structure of the channel clamp seat 240 to have multiple welds. On the one hand, the curved pipe structure in the channel clamp seat 240 will make welding difficult. On the other hand, the welding process will easily lead to leaks in the equipment that are difficult to find, and the welds will aggravate problems such as disinfection residues during the disinfection process.

[0061] It can be understood that in the embodiment of the present invention, by providing an integrally formed clamp channel seat 240 and placing it externally on the first end face 231 of the end seat 230, bending structural tubes and welding can be avoided, thereby effectively reducing the problem of disinfection residues and improving the safety of the electrically controlled endoscope; in addition, since there are no welds in the clamp channel seat 240, problems such as water leakage and circuit board short circuit caused by leakage points can also be avoided.

[0062] Figure 11 is a schematic diagram of the axial structure of the operating portion provided by an embodiment of the present invention at a third viewing angle; Figure 12 yes Figure 11 Schematic diagram of the corresponding cross-section structure.

[0063] Continue reading Figure 4 、 Figure 5 、 Figure 6、 Figure 11 and Figure 12 In an optional embodiment of the present invention, the axis of the clamp channel interface 241 is collinear with the axis of the insertion portion 110 . In other words, the rotation center of the clamp channel structure is collinear with the rotation center of the insertion portion 110 .

[0064] It can be understood that compared with the side-placed clamp channel interface 241 in the prior art, in the electrically controlled endoscope provided by the embodiment of the present invention, since the axis of the clamp channel interface 241 is geometrically coincident with the main axis of the insertion portion 110, the radial deviation of the instrument's travel path can be reduced during the instrument's passage through the clamp channel interface 241, thereby reducing the asymmetric contact friction between the instrument and the tube wall of the insertion portion 110, and reducing the instrument's pushing resistance; at the same time, the centrally symmetrical distribution characteristics of the clamp channel interface 241 can decouple the operation of the instrument from the rotational movement of the electrically controlled endoscope, and can construct mutually independent motion processes, so that the endoscope posture adjustment and the instrument operation can be carried out simultaneously, and can provide basic structural support for electrically controlled endoscopic interventional surgery.

[0065] Continue reading Figure 4 、 Figure 5 、 Figure 6 and Figure 7 In an optional embodiment of the present invention, the first optoelectronic communication interface 260 is provided at the end of the operating portion 200. In the prior art, the optoelectronic plug 400 is generally connected to the scope body 100 through a control device. It is understood that in the electrically controlled endoscope provided by the embodiment of the present invention, during use, the optoelectronic plug 400 can be directly connected to the end of the operating portion 200. This can, on the one hand, eliminate the intervention of the control device as a third transfer device, thereby improving the accuracy and efficiency of data transmission and avoiding the problem of data loss caused by the transfer; on the other hand, it can enable the operating portion 200 to be horizontally connected to the optoelectronic plug 400, eliminating the bending structure of the optical fiber within the control device and the operating portion 200, effectively avoiding the problems of severe bending and high loss of the optical fiber in the prior art, and further improving the data transmission efficiency.

[0066] Continue reading Figure 6 、 Figure 7 and Figure 10 In an optional embodiment of the present invention, the data plug 410 includes a plug housing 411, a second optoelectronic communication interface 412 and a fixing component 413. The second optoelectronic communication interface 412 is arranged at the end of the plug housing 411 and has multiple electrical connection springs. The second light guide 421 in the transmission line 420 passes through the plug housing 411 from the other end and is connected to the second optoelectronic communication interface 412. Among them, a tail sleeve 440 can be set at the coupling point between the transmission line 420 and the plug housing 411 for fixation and sealing.

[0067] The second optoelectronic communication interface 412 matches the first optoelectronic communication interface 260. The two are matching male and female interfaces and can be specifically designed according to existing technologies. The fixing assembly 413 is provided on one side of the plug housing 411. The fixing assembly 413 corresponds to the optoelectronic jack 262 on the first end surface 231 of the operating unit 200. The fixing assembly 413 is used to connect the plug housing 411 to the operating unit 200. That is, when the data plug 410 is connected to the operating unit 200, the fixing assembly 413 is used to ensure a stable connection between the first optoelectronic communication interface 260 and the second optoelectronic communication interface 412. The specific form of the fixing assembly 413 is various, such as magnetic fixation, snap connection, fastener connection, or bonding, and can be specifically selected according to actual conditions.

[0068] It will be appreciated that in the electrically controlled endoscope provided in this embodiment of the present invention, by providing a second optoelectronic communication interface 412 on the plug housing 411 that matches the first optoelectronic communication interface 260, the optoelectronic plug 400 can be directly connected to the end of the operating portion 200 during use. This eliminates the need for a control device as a third intermediate device, improves the accuracy and efficiency of data transmission, and reduces data loss caused by switching. Furthermore, the provision of the fixing assembly 413 allows for quick assembly and disassembly between the data plug 410 and the insertion portion 110. Compared to the prior art, where the scope body 100 and optoelectronic plug 400 are integrally arranged, this modularizes the structure of the electrically controlled endoscope, reduces the volume required for decontamination, and improves the convenience and flexibility of transportation and storage.

[0069] Continue reading Figure 6 and Figure 7 In an optional embodiment of the present invention, the fixing assembly 413 includes a hook 4132, a first rotating shaft 4133, a paddle 4134, and a first elastic member 4135. Accordingly, a tubular plug 4131 with a cantilever structure is formed on the side of the plug housing 411. The first rotating shaft 4133 is fixed to the inner wall of the tubular plug 4131. The hook 4132 is rotatably engaged with the tubular plug 4131 via the first rotating shaft 4133. The paddle 4134 is fixedly connected to the hook 4132, and the two can be an integral structure. The paddle 4134 is located on the outside of the tubular plug 4131 and is used to drive the hook 4132 to rotate.

[0070] The first elastic member 4135 can be configured as a coil spring or a spring spring, Figure 7 The coil spring is shown as Figure 7As shown, one end of the coil spring abuts against the inner wall of the tubular plug 4131, and the other end is connected to the hook 4132. In some optional examples, one end of the coil spring abuts against the inner wall of the tubular plug 4131, and the other end can also be connected to the paddle 4134; when the first elastic member 4135 is selected as a clockwork spring, the clockwork spring can be wound around the first rotating shaft 4133, and one end of the clockwork spring is connected to the first rotating shaft 4133, and the other end is connected to the hook 4132. Specifically, there are many ways to set the first elastic member 4135, which can be adaptively selected according to actual conditions.

[0071] The first end surface 231 of the end seat 230 of the operating part 200 is provided with a photoelectric socket 262 matching the above structure. When in use, the tubular plug 4131 is inserted into the photoelectric socket 262. During the insertion process, the portion of the hook 4132 exposed from the tubular plug 4131 is squeezed by the inner wall of the photoelectric socket 262, and the cantilever of the hook 4132 is subjected to upward (by Figure 7 The direction in is for reference only. It should be noted that the direction here is only for reference to facilitate explanation and does not serve as a specific limitation on the structure of the present invention) and then rotates around the first rotating shaft 4133. At the same time, the first elastic member 4135 will be compressed. When the hook 4132 is inserted into place, the end of the hook 4132 extending into the tubular plug 4131 will automatically reset under the push of the first elastic member 4135 and extend into the groove on the side wall of the photoelectric socket 262. That is, the hook 4132 will be hooked on the side wall of the photoelectric socket 262 to achieve a fixed connection between the photoelectric plug 400 and the mirror body 100; at the same time, the first photoelectric communication interface 260 and the second photoelectric communication interface 412 will be horizontally docked to achieve signal connection between the mirror body 100 and the photoelectric plug 400, that is, the first light guide 261 and the second light guide 421 will be docked to achieve light transmission between the mirror body 100 and the photoelectric plug 400.

[0072] Once connected, the elasticity of the first elastic member 4135 keeps the hook 4132 connected to the photoelectric jack 262, preventing accidental disconnection. To disconnect, press the paddle 4134, causing the hook 4132 to rotate and exit the groove on the side wall of the photoelectric jack 262, and then remove the photoelectric plug 400. It should be noted that the photoelectric jack 262 and the fixing assembly 413 can be provided in multiple groups, and the specific arrangement can be adapted according to actual conditions.

[0073] It can be understood that by providing components such as the hook 4132 and the first elastic member 4135, on the one hand, the optoelectronic plug 400 and the scope body 100 can be quickly plugged in and out; on the other hand, when the optoelectronic plug 400 is fixedly connected to the scope body 100, the plug can be prevented from loosening due to unexpected circumstances, thereby ensuring the safety of the electrically controlled endoscope during use.

[0074] See Figure 10 In an optional embodiment of the present invention, a communication connection socket 414 is provided on the surface of the data plug 410, and the communication connection socket 414 is used to connect to an external device. It can be understood that such a setting can improve the flexibility of the data plug 410 and enable it to be externally connected under special circumstances. Based on this, the optoelectronic plug 400 can adapt to more complex working conditions, making the electric-controlled endoscope more versatile.

[0075] Figure 13 1 is a schematic diagram of the axial structure of the water-gas plug provided by an embodiment of the present invention in another situation; Figure 14 yes Figure 13 Corresponding cross-sectional structural diagram; Figure 15 yes Figure 8 Schematic diagram of the corresponding cross-sectional structure at a certain viewing angle.

[0076] See Figure 8 、 Figure 9 、 Figure 13 、 Figure 14 and Figure 15 In an optional embodiment of the present invention, the connecting seat 310 includes a water and gas pipe seat 320, a push-pull shell 330 and a stop assembly 340. One end of the water and gas pipe seat 320 is provided with a pipe joint 323 and a cantilevered locking element 324. The locking element 324 is used to connect with the aforementioned water and gas socket 251 to achieve a fixed connection between the water and gas plug 300 and the operating part 200. The locking element 324 can choose an existing component such as an expansion buckle; the pipe joint 323 is used to connect with the aforementioned water and gas pipe 252. The water and gas conduit 350 is connected to the other end of the water and gas pipe seat 320 and is connected to the pipe joint 323. The pipe joint 323 and the water and gas conduit 350 are used to supply water or gas.

[0077] The push-pull housing 330 is sleeved over the outside of the water-gas pipe base 320 and the water-gas conduit 350. The backstop assembly 340 is sleeved over the outer shell of the water-gas conduit 350 and inserted into the interior of the push-pull housing 330. The backstop assembly 340 can slide back and forth within the inner cavity of the push-pull housing 330. The backstop assembly 340, facing the water-gas pipe base 320, is provided with latches 341. The number and position of the latches 341 correspond to the number and position of the locking elements 324. The water-gas pipe base 320, the push-pull housing 330, and the backstop assembly 340 are all made of hard plastic. The latches 341 can be integrally formed with the backstop assembly 340 or separately formed as stainless steel inserts.

[0078] During use, the push shell can be used to drive the water-gas pipe seat 320 into the water-gas interface 250 of the end seat 230. During this process, the locking element 324 will extend into the interior of the water-gas socket 251, and the pipe connector 323 will extend into the water-gas pipe 252. Then, the anti-retraction assembly 340 is pushed toward the water-gas pipe seat 320. The latch 341 on the anti-retraction assembly 340 will extend into the interior of the locking element 324, expanding the locking element 324. The protrusion on the outside of the locking element 324 will engage with the annular groove on the inner wall of the water-gas socket 251, thereby achieving a stable and fixed connection between the water-gas plug 300 and the water-gas interface 250. To release the fixation, the above steps can be reversed.

[0079] It can be understood that compared with the water-vapor plug in the prior art, the water-vapor plug 300 provided in the embodiment of the present invention has a more compact structure and is easy to plug and unplug. It makes full use of the elastic deformation of the locking element 324 itself, and can realize the quick plugging and unplugging between the water-vapor plug 300 and the water-vapor interface 250. At the same time, the present invention can realize the firm connection between the water-vapor plug 300 and the mirror body 100 through the tightening structure of the locking element 324. When the water-vapor conduit 350 is accidentally pulled, the water-vapor pipe seat 320 can be prevented from being pulled out of the mirror body 100, which is safer and more reliable than the snap-fit ​​fixing design in the prior art.

[0080] It should be noted that the number of water-gas jacks 251 can be multiple, and the number of locking elements 324 and pins 341 can be consistent with the number of water-gas jacks 251; the number of water-gas pipes 252 can also be multiple, and can be adaptively selected according to actual conditions; in an optional embodiment of the present invention, the water-gas plug 300 also includes a sealing ring, which is sleeved on the outside of the pipe joint 323. The number of sealing rings can be adaptively set to ensure the sealing of the connection between the water-gas pipe 252 and the pipe joint 323.

[0081] Continue reading Figure 8 、 Figure 9 、 Figure 13 、 Figure 14 and Figure 15 In an optional embodiment of the present invention, an observation window 331 is provided on the surface of the push-pull shell 330, and a first identification member 342 is provided at one end of the anti-retraction component 340 facing the water and gas pipe seat 320. The structure adopted in the embodiment of the present invention is a color card, and the first identification member 342 matches the position of the observation window 331 to indicate the position of the anti-retraction component 340 relative to the water and gas pipe seat 320.

[0082] Specifically, taking the color card as an example, when the backstop assembly 340 is not fully inserted (such as Figure 13 and Figure 14 As shown in FIG), the color card does not completely fill the display area of ​​the observation window 331. When the backstop assembly 340 is fully inserted (as shown in FIG), the color card does not completely fill the display area of ​​the observation window 331. Figure 8and Figure 15 As shown), it can be seen through the observation window 331 that the display area of ​​the observation window 331 has been completely filled with the color card, which means that the pin 341 of the anti-retraction component 340 is completely inserted into the interior of the locking element 324.

[0083] It can be understood that, through the cooperation of the first identification member 342 and the observation window 331, during use, it can be clearly and directly determined whether the anti-retraction component 340 is inserted into place. In other words, it can clearly and intuitively prompt the operator whether the water vapor plug 300 has been securely fixed, and can prevent accidental falling off due to insecurity.

[0084] Continue reading Figure 8 、 Figure 9 、 Figure 13 、 Figure 14 and Figure 15 In an optional embodiment of the present invention, a second identification member 343 is provided at one end of the stop assembly 340 facing the water and gas pipe seat 320. The second identification member 343 is located at the end of the first identification member 342 away from the water and gas pipe seat 320. In some cases, the first identification member 342 and the second identification member 343 can be arranged in sequence on the same card board, such as Figure 9 The second identification member 343 is also used to characterize the position of the anti-retraction assembly 340 relative to the water and gas pipe seat 320.

[0085] Specifically, taking the second identification piece 343 as an example of a color card, when the anti-retraction component 340 is not fully inserted, the second identification piece 343 can be directly observed. Based on this, the operator can be reminded that the water and gas plug 300 is not fully inserted. When the anti-retraction component 340 is fully inserted, the second identification piece 343 will be completely covered by the push-pull shell 330.

[0086] It can be understood that by setting the second identification part 343, a judgment method different from the judgment method of the first identification part 342 can be provided. These two methods can be used separately or simultaneously, and can be adaptively set according to actual conditions. It can be understood that when the first identification part 342 and the second identification part 343 are set at the same time, the first identification part 342 and the second identification part 343 can be redundant with each other on the one hand, and can verify each other on the other hand to ensure the accuracy of the provided position information.

[0087] In an optional embodiment of the present invention, the first identification member 342 and the second identification member 343 can adopt the color card as mentioned above, or can adopt a scale or other eye-catching marking structure; when selecting a color card, more eye-catching colors such as green, red, yellow and cyan can be given priority. When the first identification member 342 and the second identification member 343 are set at the same time, they need to use different colors, for example, the first identification member 342 is green and the second identification member 343 is red; or the first identification member 342 is green and the second identification member 343 is yellow; or the first identification member 342 is cyan and the second identification member 343 is red; or the first identification member 342 is cyan and the second identification member 343 is red; or the first identification member 342 is cyan and the second identification member 343 is yellow. Specifically, it can be adaptively set according to actual conditions.

[0088] Figure 16 yes Figure 8 Schematic diagram of the corresponding cross-sectional structure from another perspective.

[0089] See Figure 9 and Figure 16 In an optional embodiment of the present invention, the surface of the water / gas pipe seat 320 is provided with a first rib 321 and a second rib 322. The first rib 321 and the second rib 322 can be formed by grooves in the surface of the water / gas pipe seat 320. The first rib 321 is provided on the side of the second rib 322 facing the locking element 324. The inner wall of the push-pull shell 330 is provided with a first hook 332 corresponding to the position of the first rib 321, and the backstop assembly 340 is provided with a second hook 345 corresponding to the position of the second rib 322. When the locking element 324 is connected to the water / gas socket 251, the distance between the first rib 321 and the first hook 332 is equal to the distance between the second rib 322 and the second hook 345.

[0090] The process of releasing the water-gas plug 300 from the water-gas interface 250 is as follows: first, the push-pull shell 330 can be pulled in the direction away from the locking element 324. During this process, the shoulder of the push-pull shell 330 will abut against the shoulder of the stop assembly 340, thereby driving the stop assembly 340 to move synchronously. The latch 341 will exit the locking element 324 as the push-pull shell 330 moves, and the locking element 324 will return to its original shape due to its own elasticity. When the push-pull shell 330 moves to the point where the first retaining edge 321 and the first hook 33 When the second rib 322 abuts against the second hook 345, the push-pull housing 330 drives the water-gas pipe seat 320 from one side thereof to move away from the water-gas interface 250 via the first rib 321 and the first hook 332. The retaining assembly 340 drives the water-gas pipe seat 320 from the other side thereof to move away from the water-gas interface 250 via the second rib 322 and the second hook 345 until the locking element 324 is pulled out of the water-gas socket 251.

[0091] It can be understood that in the electric-controlled endoscope provided in an embodiment of the present invention, by providing matching first ribs 321 and first hooks 332, as well as matching second ribs 322 and second hooks 345, the water-vapor plug 300 can be separated from the water-vapor interface 250 only by means of the movable push-pull shell 330. This method is simple and direct, and can improve the efficiency of disassembly of the water-vapor plug 300. In addition, when the water-vapor plug 300 is separated from the scope body 100, the first ribs 321 and the first hooks 332 are hooked with each other, and the second ribs 322 and the second hooks 345 are hooked with each other. Based on this, the water-vapor pipe seat 320, the push-pull shell 330 and the anti-retraction assembly 340 can be in a floating connection state, that is, the three are in an incomplete engagement and incomplete separation. This structure can improve the integrity of the three and facilitate the transportation and storage of the water-vapor plug 300.

[0092] Figure 17 1 is another structural schematic diagram of a water-gas conduit provided in an embodiment of the present invention; Figure 18 yes Figure 17 Schematic diagram of the corresponding explosion structure; Figure 19 This is another structural schematic diagram of the water-gas conduit provided by an embodiment of the present invention.

[0093] See Figure 8 、 Figure 9 、 Figure 17 、 Figure 18 and Figure 19 In the optional embodiment of the present invention, the water-gas conduit 350 has a variety of optional structures. The following examples take two water-gas conduits 350 as an example; Structure 1: Two water-gas conduits 350 are arranged in parallel and spaced apart (such as Figure 8 and Figure 9 Structure 2: Two water and gas conduits 350 are arranged in parallel and fixed together (as shown); Figure 17 and Figure 18 Structure 3: The water-gas conduit 350 uses a multi-lumen tube, and the appearance features show a single tube (such as Figure 19 The above examples illustrate specific optional configurations provided by the present invention, which can be adapted to meet specific needs. It will be appreciated that the various optional configurations for the water-gas conduit 350 effectively enhance the versatility of the water-gas plug 300, allowing the water-gas conduit 350 and the electronically controlled endoscope to be flexibly adapted for more complex situations, thereby enabling both to meet a wider range of operating conditions. It should be noted that the number of water-gas conduits 350 can be further increased, and their evolving configurations can be referenced in the examples provided in the above embodiments, and will not be detailed here.

[0094] Figure 20 is a schematic diagram of an exploded structure of an operating portion provided by an embodiment of the present invention in another situation; Figure 211 is a schematic diagram of the shaft side structure of a transmission assembly provided by an embodiment of the present invention; Figure 22 is an axial cross-sectional side view of a transmission assembly provided by an embodiment of the present invention; Figure 23 is a schematic cross-sectional structural diagram of a transmission assembly provided by an embodiment of the present invention; Figure 24 It is a schematic diagram of the exploded structure of the shaft sleeve and the second rotating shaft provided in an embodiment of the present invention.

[0095] See Figures 20 to 24 In an optional embodiment of the present invention, the operating portion 200 further includes a transmission assembly 270, which is disposed on a side of the handle housing 211. The transmission assembly 270 is configured to drive the bending portion 120 to bend under the drive of an external driving device, that is, the transmission assembly 270 is configured to control the bending portion 120. The external driving device may refer to the prior art, and details will not be detailed herein.

[0096] The transmission assembly 270 includes a sleeve 271, a second rotating shaft 272 and a second elastic member 273. Corresponding to the transmission assembly 270, the operating part 200 also includes a support assembly 210. The support assembly 210 includes the aforementioned handle housing 211 and a base plate 212 arranged inside the handle housing 211. In some optional embodiments, the handle housing 211 can be an integrated structure with the base plate 212; the surface of the support assembly 210 is provided with a recessed mounting portion, and the mounting portion is used to install and fix the transmission assembly 270. Specifically, the mounting portion is formed by the through hole on the handle housing 211 and the base plate 212. In some optional embodiments, a limiting groove can also be provided on the base plate 212, that is, the limiting groove and the through hole on the handle housing 211 together form a mounting portion. The specific structure of the mounting portion can be adaptively adjusted according to the installation requirements of the transmission assembly 270, and this article does not make too many restrictions on this.

[0097] The shaft sleeve 271 is fixed to the opening of the mounting portion (i.e., the through hole of the handle housing 211) and is fixedly connected to the bottom plate 212. The top of the inner wall of the shaft sleeve 271 is provided with a first limit portion 2711; the second rotating shaft 272 is provided inside the mounting portion and can reciprocate along the shaft hole of the shaft sleeve 271. It can also be understood that the second rotating shaft 272 can move up and down relative to the shaft sleeve 271 (to Figure 23For reference, the upper, lower, top or bottom here are merely schematic expressions and are not intended to be a specific limitation on this embodiment). The first end of the second rotating shaft 272, that is, the end of the second rotating shaft 272 facing the top of the sleeve 271 is provided with a second limiting portion 2721, and the second limiting portion 2721 matches the first limiting portion 2711. The first limiting portion 2711 and the second limiting portion 2721 are used to limit the rotation of the second rotating shaft 272 relative to the sleeve 271. In this embodiment, the first end of the second rotating shaft 272 is also provided with a connecting hole 2722 for connection to an external drive device. The second end of the second rotating shaft 272, that is, the end away from the top of the sleeve 271 is used to control the bending portion 120.

[0098] It should be noted that there are many ways to cooperate between the first limiting portion 2711 and the second limiting portion 2721, such as meshing of gear teeth or frictional cooperation of friction surfaces, and can be selected according to actual conditions. The second elastic member 273 is sleeved on the outside of the second rotating shaft 272, with one end of the second elastic member 273 abutting the shoulder of the second rotating shaft 272, and the other end of the second elastic member 273 abutting the bottom of the mounting portion, i.e., the base plate 212.

[0099] When the transmission assembly 270 is not connected to the external driving device, the first end of the second rotating shaft 272 will abut against the sleeve 271 with the support of the second elastic member 273. At this time, the first limiting portion 2711 and the second limiting portion 2721 will fit together, thereby limiting the movement of the second rotating shaft 272 relative to the sleeve 271; in use, when the second rotating shaft 272 is connected to the external driving device, the driving shaft 281 of the external driving device will extend into the connecting hole 2722 of the second rotating shaft 272 and push the second rotating shaft 272 downward for a distance. At this time, the first limiting portion 2711 will separate from the second limiting portion 2721, that is, the sleeve 271 will release the restriction on the second rotating shaft 272, and the second rotating shaft 272 can rotate relative to the sleeve 271, and then the bending portion 120 can be controlled by controlling the external driving device.

[0100] See Figures 20 to 24 It can be understood that, in the electrically-controlled endoscope provided in the embodiment of the present invention, when the connection between the external driving device and the second rotating shaft 272 is released, the second elastic member 273 pushes the first end of the second rotating shaft 272 to move toward the sleeve 271, thereby causing the second limiting portion 2721 of the second rotating shaft 272 to abut and fit against the first limiting portion 2711 of the sleeve 271. In this way, the bending angle of the bending portion 120 can be instantly locked, so that it maintains the real-time bending shape before the connection between the driving device and the second rotating shaft 272 is released, and the electrically-controlled endoscope has the function of maintaining the motion state.

[0101] Compared with the prior art, the electric-controlled endoscope provided in the embodiment of the present invention has a motion state maintenance function that enables the bending portion 120 of the electric-controlled endoscope to maintain its real-time bending shape before the power outage or emergency interruption in an unexpected situation when the external driving structure encounters a power outage or emergency power interruption. This can solve the rebound problem caused by the elastic deformation of the bending portion 120 of the traditional electric-controlled endoscope in an emergency situation, and can fundamentally avoid the unexpected collision between the bending portion 120 of the electric-controlled endoscope and the fragile tissue in the patient's body due to rebound reset, thereby reducing the risk of tissue damage caused by such collision, and can effectively improve the safety of the electric-controlled endoscope in clinical applications.

[0102] See Figures 21 to 23 In an optional embodiment of the present invention, in order to achieve the sealing of the electric-controlled endoscope, the transmission assembly 270 also includes a first sealing ring 274 and a second sealing ring 275. The first sealing ring 274 is sleeved on the sleeve 271 to achieve sealing between the sleeve 271 and the handle housing 211; the second sealing ring 275 is sleeved on the second rotating shaft 272 to achieve sealing between the second rotating shaft 272 and the sleeve 271.

[0103] See Figures 21 to 23 In an optional embodiment of the present invention, the support assembly 210 also includes a core shaft 213, which is arranged on the surface of the base plate 212. The position of the core shaft 213 corresponds to the position of the through hole on the handle housing 211, that is, corresponds to the position of the opening of the mounting portion. When a limiting groove is provided on the base plate 212, the core shaft 213 is provided in the limiting groove; the second end of the second rotating shaft 272 is sleeved on the core shaft 213 and is suitable for reciprocating movement along the axis of the core shaft 213. The outer sides of the core shaft 213 and the second rotating shaft 272 are jointly sleeved with a sprocket 2712. In other words, a part of the sprocket 2712 is sleeved on the core shaft 213, and the other part is sleeved on the second rotating shaft 272.

[0104] One end of the second elastic member 273 abuts against the shoulder of the second rotating shaft 272, and the other end abuts against the top of the sprocket 2712. The second rotating shaft 272 is used to drive the sprocket 2712 to rotate so as to control the bending portion 120; specifically, the transmission assembly 270 also includes a chain 276 and a traction line 277. The chain 276 is wound around the sprocket 2712, one end of the chain 276 is connected to a traction line 277, and the other end of the chain 276 is connected to another traction line 277. The ends of the two traction lines 277 away from the chain 276 are respectively connected to the bending portion 120. When in use, the second rotating shaft 272 drives the sprocket 2712 to rotate, the sprocket 2712 drives the chain 276 to rotate, and the chain 276 drives the traction line 277 to move, thereby realizing control of the bending portion 120.

[0105] It can be understood that in the electrically controlled endoscope provided in the embodiment of the present invention, by providing the core shaft 213, the stability of the second rotating shaft 272 and the sprocket 2712 can be improved, and radial movement of the two can be avoided during rotation. Secondly, the core shaft 213 can also ensure the coaxiality between the second rotating shaft 272 and the sprocket 2712, thereby ensuring the synchronous rotation of the two, improving the integrity of the transmission assembly 270, and improving the transmission accuracy and transmission efficiency.

[0106] Continue reading Figures 21 to 23 In an optional embodiment of the present invention, the transmission assembly 270 also includes a first gear 278, a second gear 279 and a sensor 2710. The first gear 278 is sleeved on the second rotating shaft 272 and is located between the shoulder of the first end of the second rotating shaft 272 and the sprocket 2712. The second rotating shaft 272 is used to drive the first gear 278 to rotate. The cooperation between the two can be a key and keyway or a groove structure. The embodiment of the present invention does not make specific limitations on this.

[0107] One end of the second elastic member 273 abuts against the shoulder of the first end of the second rotating shaft 272, and the other end abuts against the first gear 278. That is, in this embodiment, the other end of the second elastic member 273 is indirectly abutted against the bottom of the mounting portion through the first gear 278 and the sprocket 2712; the second gear 279 is rotatably arranged on the surface of the base plate 212 and meshes with the first gear 278. The sensor 2710 is arranged on the second gear 279, and the sensor 2710 is used to monitor the rotation of the second gear 279.

[0108] When the second rotating shaft 272 rotates, the first gear 278 and the second gear 279 rotate accordingly. At this time, the sensor 2710 can monitor the rotation angle of the second gear 279. Through simple calculation, the movement distance of the chain 276 can be obtained, and the bending angle of the bending portion 120 can be obtained. It can be understood that the arrangement of the first gear 278, the second gear 279, and the sensor 2710 allows the operator to directly obtain the specific bending condition of the bending portion 120, providing reliable data support for interventional surgery using an electronically controlled endoscope.

[0109] Continue reading Figure 22 and Figure 23In an optional embodiment of the present invention, the electrically-controlled endoscope further includes a handwheel 280 and a dynamic ring 290. A drive shaft 281 is provided on one side of the handwheel 280, and the dynamic ring 290 is sleeved on the outside of the drive shaft 281; in the case of manual drive, the drive shaft 281 is connected to the first end of the second rotating shaft 272 so as to be used for manually controlling the bending portion 120, and the end of the dynamic ring 290 away from the handwheel 280 is connected to the sleeve 271, and the dynamic ring 290 is used to limit the axial movement of the handwheel 280 relative to the second rotating shaft 272, that is, to prevent the handwheel 280 from accidentally falling off from the second rotating shaft 272.

[0110] In an optional example of the present invention, the movable ring 290 and the handwheel 280 can be independent components or an integrated component, and can be adaptively set according to actual conditions. When the movable ring 290 and the handwheel 280 are independent components, limiting components such as baffles can also be set so that the movable ring 290 is fixed on the driving shaft 281 of the handwheel 280. In an embodiment of the present invention, the movable ring 290 and the handwheel 280 can rotate with each other. When the two are an integrated component, or the two cannot rotate relative to each other, the movable ring 290 and the sleeve 271 can rotate with each other, so that the sleeve 271 can avoid restricting the rotation of the handwheel 280.

[0111] It is understandable that in the electrically controlled endoscope provided in the embodiment of the present invention, by providing the hand wheel 280 and the dynamic ring 290, an optional manual drive can be provided for the electrically controlled endoscope in addition to the electric drive mode, which can make the electrically controlled endoscope more versatile. Compared with the electrically controlled endoscopes in the prior art, in an emergency, when the external electrically controlled drive device fails, the operator can use the hand wheel 280 to achieve emergency control of the electrically controlled endoscope, which can effectively reduce the safety risks of the electrically controlled endoscope.

[0112] Continue reading Figure 22 and Figure 23 In an optional embodiment of the present invention, the dynamic ring 290 includes a plurality of elastic cantilevers 291 disposed around the shaft sleeve 271. The surface of the shaft sleeve 271 is provided with slots corresponding to the number and position of the elastic cantilevers 291. During manual operation, each elastic cantilever 291 is respectively engaged in a corresponding slot. It is understood that during manual operation, the handwheel 280 can be pressed downward to separate the second rotating shaft 272 from the shaft sleeve 271, thereby separating the first limiting portion 2711 and the second limiting portion 2721. At this time, rotating the handwheel 280 can achieve control of the bending portion 120. When the pressure on the handwheel 280 is released, the handwheel 280 and the second rotating shaft 272 return to their original positions under the push of the elastic cantilevers 291 and the second elastic member 273. At this time, the first limiting portion 2711 re-engages the second limiting portion 2721 and restricts the rotation of the second rotating shaft 272.

[0113] During this process, the elastic deformation of the elastic cantilever 291 allows the handwheel 280 to push the first rotating shaft 4133 without separating the handwheel 280 from the sleeve 271, thereby ensuring that the handwheel 280 remains stably connected to the sleeve 271 during use to avoid the impact of accidental detachment on operation.

[0114] Figure 25 It is a schematic diagram of the assembly structure of the elastic ring provided in an embodiment of the present invention.

[0115] See Figure 25 In an optional embodiment of the present invention, the dynamic ring 290 includes an elastic ring 292. Unlike the aforementioned embodiment, in this embodiment, in the case of manual drive, the elastic ring 292 is magnetically engaged with the sleeve 271. That is, in this embodiment, the axial movement of the handwheel 280 relative to the second rotating shaft 272 can be limited by magnetic engagement. Specifically, the elastic ring 292 can be set to a magnetic material, and the sleeve 271 can be set to a material that can be adsorbed by a magnet.

[0116] It can be understood that the handwheel 280 can be simply and directly fixed to the sleeve 271 through magnetic attraction, and the handwheel 280 and the elastic ring 292 can be quickly disassembled and assembled. In an emergency, the switching efficiency from electric control to manual control can be effectively improved, which can save more time for the operator.

[0117] See Figure 20 In an optional embodiment of the present invention, the number of transmission components 270 can be one or more, and correspondingly, the number of hand wheels 280 is consistent with the number of transmission components 270, which is not specifically limited in this embodiment of the present invention.

[0118] In an optional embodiment of the present invention, when manually controlled components such as the handwheel 280 are provided simultaneously with the detachable water-vapor plug 300 and the photoelectric plug 400 of the aforementioned embodiment, in addition to the beneficial effects described in the aforementioned corresponding embodiment, the manual control can be combined with the photoelectric plug 400 to form an electrically controlled endoscope that can be directly manually controlled, i.e., an electrically controlled endoscope of a split design; in an emergency, the manual control can be combined with the photoelectric plug 400 to control the electrically controlled endoscope to be withdrawn from the patient's body, which can effectively improve the safety of the electrically controlled endoscope during clinical application. Secondly, the combination of the manual control and the photoelectric plug 400 allows for simultaneous observation of images and manual control of the operation of the electrically controlled endoscope, which can meet the needs of some simple electrically controlled endoscopic interventional surgeries and provide greater flexibility than the electrically controlled method of the electrically controlled endoscope.

[0119] In an optional embodiment of the present invention, a membrane switch or operating button can also be set on the surface of the handle housing 211 to control the external gas or liquid to be delivered to the interior of the electric-controlled endoscope through the water-gas conduit 350. Specifically, it can be adaptively set according to actual conditions, and will not be repeated here.

[0120] It should be noted that the technical solutions in the various embodiments of the present invention can be combined with each other, but the basis for the mutual combination is that it can be implemented by ordinary technicians in this field; when the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist, that is, it does not fall within the scope of protection of the present invention.

[0121] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
