Description

Technical Field

[0001] The present application relates to the technical field of endoscopes, and in particular to a disposable endoscope housing, a reusable endoscope module, and an endoscope device. Background Art

[0002] Endoscopes are a comprehensive medical detection tool that integrates traditional optics, ergonomics, precision mechanical technology, modern electronics, mathematics and software technology. Endoscopes can enter the stomach through the mouth or other natural openings in the body to enter the interior of the organism, and can reveal disease changes that X-rays cannot show. Therefore, they are of great value in the field of medical diagnosis. Endoscopes are generally equipped with image sensors, optical lenses, lighting systems and mechanical components. As a precision electronic device, endoscopes have a complex structure and are difficult to clean and disinfect thoroughly. The use of the same endoscope between different patients can easily lead to cross-infection, which in turn causes serious damage to the health of the infected person, and even endangers their lives. After years of exploration in the industry, disposable endoscope technology has been developed, but traditional disposable endoscope equipment has two types of defects. One is that the lens and sensor are included in the disposable replacement parts, which greatly increases the manufacturing and use costs; the other is to set up multiple disposable parts, each of which is replaced separately, which increases the complexity of use and is not easy to adapt to other structures.

[0028] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0029] Refer to Figure 1, which shows a schematic diagram of the use of an endoscope device 1 in an embodiment of the present application. The endoscope device 1 provided in an embodiment of the present application includes an endoscope module 100 and a disposable endoscope shell 200. The disposable endoscope shell 200 can be detachably connected to the endoscope module 100, and the separated disposable endoscope shell 200 can be replaced after use. The endoscope module 100 can at least realize the image acquisition and image transmission functions required by the endoscope device 1, and the endoscope module 100 can be used repeatedly.

[0030] The disposable endoscope housing 200 includes an operating portion 210 and an insertion portion 220. The operating portion 210 is provided with a module inlet 211, and the module inlet 211 is used for inserting the endoscope module 100, and the module inlet 211 cooperates with the proximal end of the endoscope module 100. The proximal end of the insertion portion 220 is connected to the operating portion 210, and the distal end of the insertion portion 220 cooperates with the distal end of the endoscope module 100. An insertion channel for the endoscope module 100 to pass through is formed in the insertion portion 220, and the insertion channel is communicated with the module inlet 211.

[0031] The disposable endoscope housing 200 can be replaced as an integral component, and the disposable endoscope housing 200 is provided with an operating portion 210 and an insertion portion 220. When installing and replacing the disposable housing, the operating portion 210 is used to be held by the user and used to install an independent endoscope module 100. When using the endoscope device 1, the operating portion 210 is used to be held by the user to assist in performing corresponding operations. The insertion portion 220 is used to accommodate and position the endoscope module 100, can penetrate into the organism, and is used to isolate the endoscope module 100 and the organism to avoid infection of the organism. By providing the disposable endoscope housing 200, the endoscope module 100 that realizes the required functions of the endoscope device 1 can be reused as an independent component. Under the premise of ensuring safety, the manufacturing cost is reduced, the replacement is more convenient, the number of times the module is used is greatly increased, and resource waste is avoided; the disposable endoscope housing 200 itself is a disposable structure, which can be independently designed according to different organisms or medical scenarios, thereby improving the overall applicability of the device.

[0032] The operating part 210 can be designed to be more user-friendly and has a hollow structure. The operating part 210 is provided with a cavity connected to the insertion channel and the module entrance 211. The operating part 210 is located at the proximal end of the insertion part 220 and is sealed to the insertion part 220.

[0033] As shown in Fig. 2, the operation part 210 is also provided with an instrument passage hole 213, which is spaced apart from the module entrance 211 for instruments to enter the insertion part 220. The insertion part 220 is provided with an instrument tube 222, which is a tubular structure for accommodating instruments.

[0034] Specifically, the insertion portion 220 is a tubular structure, and the hollow portion inside is the insertion channel 201. The length of the insertion portion 220 is designed as required. The entire or part of the insertion portion 220 is made of a flexible material. The insertion portion 220 at least includes a portion that can be bent, and the bent portion can be a flexible material or a bendable structure made of a rigid material. In other embodiments, the insertion portion 220 can also be made of a rigid material.

[0035] The distal end of the insertion portion 220 has an opening 202, and the proximal end is connected to (or integrally formed with) the operating portion 210. The opening 202 of the insertion portion 220 is used to expose the endoscope module from the opening 202 to achieve the above-mentioned functions. The diameter of the insertion channel 201 is larger than the outer diameter of the endoscope module to accommodate structures such as the endoscope module. It can be understood that all "distal ends" and "proximal ends" of different structures in this document refer to the same direction, and the "distal end" is the direction in which the endoscope device 1 is farther away from the operator when in use, and the "proximal end" is the direction in which the endoscope device 1 is closer to the operator when in use.

[0036] In one embodiment, the insertion portion 220 is provided with a positioning groove, and the positioning groove is used to limit the distal end of the endoscope module 100 to a preset position. The preset position is that the distal end of the endoscope module 100 is inside the insertion portion 220 (including the situation that the distal end of the endoscope module 100 is flush with the edge of the opening 202 of the insertion portion 220), or the distal end of the endoscope module 100 extends out of the insertion portion 220 by a preset distance. Specifically, after the positioning groove is connected to the corresponding structure of the endoscope module 100, the position of the endoscope module 100 can be limited in the axial and / or circumferential direction. It can be understood that the positioning groove can be set along the entire insertion portion 220, or can be set at a partial position of the insertion portion 220, such as the distal end of the insertion portion 220.

[0037] As shown in FIG5 , in some cases, such as when the operating environment requirements for the endoscope device 1 are relatively strict, a transparent end plate is provided at the opening 202 to close the opening 202 of the insertion portion 220, and the distal end of the endoscope module 100 cannot extend out of the opening 202. In some cases, such as when the operating environment requirements for the endoscope device 1 are not high, the opening 202 is directly connected to the outside, and the distal end of the endoscope module 100 can extend out of the opening 202 by a preset distance.

[0038] The positioning groove is protruding or recessed on the inner wall of the insertion channel 201, and the positioning groove includes a first positioning groove 223 and a second positioning groove 224. As shown in FIG5(1), the first positioning groove 223 is inserted along the axial direction of the insertion portion 220, and is used to cooperate with the positioning groove to limit the circumferential position of the endoscope module 100, so that the endoscope module 100 does not rotate circumferentially. As shown in FIG5(2), the second positioning groove 224 is inserted near the opening 202 and along the circumferential direction of the insertion portion 220, and is used to cooperate with the positioning groove to limit the axial position of the endoscope module 100, so that the endoscope module 100 stops extending after it extends to the position limited by the second positioning groove 224. In particular, as shown in FIG7, the second positioning groove 224 is closer to the opening 202 of the insertion portion 220 than the first positioning groove 223. When the endoscope module 100 is extended, the circumferential position is first limited, and it can still further move axially to a preset position.

[0039] Preferably, the first positioning groove 223 and the second positioning groove 224 are both protrudingly arranged on the inner wall of the insertion channel 201, and the structure matching the endoscope module 100 with the first positioning groove 223 is recessed, which makes it easier for the endoscope module 100 to move inside the insertion channel 201, and the protruding second positioning groove 224 can more easily limit the axial movement of the endoscope module 100.

[0040] It is understandable that when an end plate is provided at the opening 202 , the second positioning groove 224 may not be provided.

[0041] In one embodiment, the disposable endoscope housing 200 further includes a locking member 300, which is detachably connected to the module entrance 211 and is used to limit the axial position of the proximal end of the endoscope module 100 relative to the module entrance 211. The locking member 300 belongs to the disposable endoscope housing 200 and is a disposable replacement component. When the disposable endoscope housing 200 is not in use, the locking member 300 is detachably connected to the operating part 210 and is arranged at the module entrance 211. When the disposable endoscope housing 200 is in use, the locking member 300 is removed from the module entrance 211. When or after the endoscope module 100 enters, the locking member 300 cooperates with the endoscope module 100. After the distal end of the endoscope module 100 reaches a preset position, the locking member 300 locks the endoscope module 100 and the operating part 210 with each other.

[0042] Furthermore, the locking piece 300 has a through hole. When or after the endoscope module 100 enters, the locking piece 300 is separated from the operating part 210 or is not completely separated. The endoscope module 100 passes through the through hole and is arranged in the locking piece 300. After the distal end of the endoscope module 100 reaches a preset position, the locking piece 300 is connected to the module entrance 211 to lock the endoscope module 100.

[0043] The disposable endoscope housing 200 further includes an elastic member (not shown) disposed between the module entrance 211 and the locking member 300, and the locking member 300 can be locked relative to the operating portion 210 to squeeze the elastic member. Specifically, the elastic member is annular and disposed at the periphery of the module entrance 211, and the endoscope module 100 can pass through the locking member 300 and the elastic member. For example, the locking member 300 and the operating portion 210 are detachably connected in a threaded connection, and the locking member 300 moves along the thread toward the operating portion 210 and squeezes the elasticity. After being squeezed, the elastic member is elastically deformed and squeezed toward the endoscope module 100 and the operating portion 210 to fill the space between the operating portion 210, the locking member 300 and the endoscope module 100, until the endoscope module 100 can no longer move under the action of the elastic member, and the locking member 300 cooperates with the positioning groove to complete the locking of the proximal and distal ends of the endoscope module 100.

[0044] The locking member 300 has an extrusion end 310, which is detachably inserted into the module inlet 211 and connected to the module inlet 211. As shown in FIG4 (1), the extrusion end 310 may be conical, the maximum outer diameter of the extrusion end 310 is greater than the inner diameter of the module inlet 211, and the minimum outer diameter of the extrusion end 310 is less than or equal to the inner diameter of the module inlet 211, so that after the locking member 300 is locked, the cone can be interference fit with the module inlet 211, and the elastic member is located between the extrusion end 310 and the module inlet 211. It can be understood that, as shown in FIG4 (2), the extrusion end 310 may be cylindrical, and the corresponding module inlet 211 is conical, so that the two gradually interfere with each other to extrude the elastic member as the locking member 300 enters.

[0045] In one embodiment, the operating portion 210 is provided with a connection end 212, and the connection end 212 is used to connect to the plug connector 140 of the endoscope module 100. The disposable endoscope housing 200 also includes a lighting assembly 400 disposed in the insertion channel 201, and a light-emitting element for lighting is provided at the distal end of the lighting assembly 400, and the light-emitting element cooperates with the distal end of the insertion portion 220, and the plug connector 140 and the connection end 212 can be electrically connected to supply power to the lighting assembly 400.

[0046] The lighting assembly 400 includes a light-emitting element and its circuit. The lighting assembly 400 has a low cost. The lighting assembly 400 can be set in the disposable endoscope housing 200 as a disposable replacement component. By setting the plug connector 140 and the connection end 212, the endoscope module 100 can power the structure such as the illumination component in the disposable endoscope housing 200, and plug and play is performed at the operating part 210, which is convenient for connection. The light-emitting element is fixed or integrally formed at the far end of the insertion channel 201, and the light-emitting element can be located near the opening 202, and the light-emitting element avoids the above-mentioned positioning groove. In other embodiments, the circuit is an optical fiber. Due to the excellent light-guiding performance of the optical fiber, the light-emitting element can be set at any position.

[0047] In some embodiments, the insertion channel 201 of the insertion part 220 is further provided with a module channel tube 221 for independently accommodating the endoscope module 100. The module channel tube 221 is similar in material structure and length to the insertion part 220 to ensure the consistency of the action. The module channel tube 221 is fixed at a fixed position in the insertion part 220, and the distal end of the module channel tube 221 is flush with the distal end of the insertion part 220. The inner diameter of the module channel tube 221 is slightly larger than the outer diameter of the endoscope module 100. The first positioning groove 223 and the second positioning groove 224 are both provided in the module channel tube 221. The insertion channel 201 is further provided with an illumination tube and an instrument tube 222 for the illumination assembly 400 to pass through, and a plurality of illumination tubes and corresponding illumination assemblies 400 may be provided.

[0048] The endoscope module 100 is detachably connected to the disposable endoscope housing 200, and the endoscope module 100 is a reusable component. In one embodiment, as shown in FIG3 , the endoscope module 100 includes an imaging element 110, a sheath 130, and a packaging head 120, wherein the sheath 130 is made of a flexible material and is used to accommodate a circuit connected to the imaging element 110, and the packaging head 120 is disposed at the distal end of the sheath 130, and the imaging element 110 is installed in the packaging head 120.

[0049] Specifically, the sheath 130 has a cylindrical structure, the imaging element 110 is exposed from one end of the cylinder, the packaging head 120 is also cylindrical and can be connected to one end of the sheath 130 or sleeved outside the sheath 130, the collecting end of the imaging element 110 is exposed from one end of the packaging head 120, and the packaging head 120 packages the sheath 130 and the imaging element 110 into an integral structure.

[0050] In one embodiment, the endoscope module 100 includes a plug connector 140 for connecting an imaging device, and the plug connector 140 is located at the proximal end of the endoscope module 100. After the endoscope module 100 is connected to the disposable endoscope housing 200, the plug connector 140 is located outside the operating part 210.

[0051] Specifically, the plug connector 140 passes through the sheath 130, and an electrical terminal 141 is provided on the plug connector 140. The connection end 212 on the operating portion 210 is in the shape of a hole, and a sensing terminal is provided in the hole. The plug connector 140 is in the shape of a pin, and the plug connector 140 extends into the connection end 212 so that the sensing terminal and the electrical terminal 141 are electrically connected. After the connection, the endoscope module 100 can supply power to the power-demanding structure of the disposable endoscope housing 200. The plug connector 140 and the module inlet 211 are arranged in parallel on the outer surface of the operating portion 210. After the endoscope module 100 is partially extended into the disposable endoscope housing 200, the position of the plug connector 140 is adapted to the position of the connection end 212.

[0052] In one embodiment, a locking member 300 is further included, and the locking member 300 is detachably connected to the module inlet 211 and is used to limit the axial position of the proximal end of the endoscope module 100 relative to the module inlet 211. The locking member 300 does not belong to the disposable endoscope housing 200, and the locking member 300 is independently provided or sleeved on the endoscope module 100 for use. An elastic member is provided between the endoscope module 100 and the module inlet 211, and the elastic member can be used as a non-disposable element.

[0053] In one embodiment, the endoscope module 100 is provided with a positioning portion, and the insertion portion 220 is provided with a positioning groove, and the positioning groove is connected to the positioning portion to limit the distal end of the endoscope module 100 to a preset position. As shown in Figures 5, 6, and 7, the positioning portion matches the first positioning groove 223 and the second positioning groove 224, and includes a first positioning portion 121 and a second positioning portion 122, wherein the first positioning portion 121 is a groove axially arranged on the packaging head 120, and is used to cooperate with the positioning groove to limit the circumferential position of the endoscope module 100, and the second positioning portion 122 is a notch circumferentially arranged on the packaging head 120, and is used to cooperate with the positioning groove to limit the axial position of the endoscope module 100.

[0054] In particular, the second positioning portion 122 is closer to the opening 202 of the insertion portion 220 than the first positioning portion 121. Specifically, the second positioning portion 122 is located at the edge of the opening 202. A step surface is formed at the intersection of the second positioning portion 122 and the first positioning portion 121. The step surface is limited by the edge of the second positioning groove 224. Part of the structure of the second positioning portion 122 can go over the second positioning groove 224. The axial length of the second positioning portion 122 is greater than the axial length of the second positioning groove 224, so that the imaging element 110 can extend out of the opening 202 by a preset distance.

[0055] In one embodiment, the endoscope module 100 further includes an imaging connection portion 150, wherein the imaging connection end 150 and the imaging element 110 are respectively located at two ends of the line, and the sheath 130 is located therebetween. The imaging connection portion 150 is used to connect to an external imaging device, and can read the data fed back by the imaging element 110 in real time through the imaging device.

[0056] In one embodiment, the endoscope device 1 also includes a lighting assembly 400 arranged in the insertion channel 201. The lighting assembly 400 is used as a non-disposable component. The lighting assembly 400 can be integrated with the endoscope module 100 or can be used as an independent module. In this case, there is no need to set corresponding connection terminals 212 and plug connectors 140 on the operating part 210 and the endoscope module 100.
