[0059] This application discloses a handle structure and an electronic bronchoscope, which include some or all of the technical features of the following embodiments; that is, the handle structure and the electronic bronchoscope include some or all of the following structures. In an embodiment of this application, a handle structure includes a handle end, an insertion end, a suction valve assembly and an adjustment assembly; the adjustment assembly includes an adjustment part and a replacement part, and the suction valve assembly includes a mating male suction valve connector and a female suction valve connector; the adjustment part and the male suction valve connector are arranged in the handle end, and the replacement part and the female suction valve connector are arranged in the insertion end; the insertion end is detachably connected to the handle end, and in the state where the insertion end is connected to the handle end, the male suction valve connector is connected to the female suction valve connector to achieve pipeline connection and electrical connection; the adjustment part and the replacement part are in gear engagement, and at least one of the adjustment part and the replacement part passes through at least one of the male suction valve connector and the female suction valve connector. The above handle structure, through the handle end, the male suction valve connector and the adjustment part, in cooperation with the insertion end, the female suction valve connector and the replacement part, realizes pipeline connection and electrical connection while disassembling and replacing, thereby improving the efficiency and reliability of disassembly and replacement. On the one hand, it realizes rapid disassembly and replacement of the insertion end while retaining the handle end, so as to enter the treatment faster, and during use, except for the insertion end, the rest of the parts do not need to be disinfected and sterilized; after operation, the used insertion end can be discarded, which is conducive to preventing cross-infection; on the other hand, since the handle end is retained, it greatly saves the use cost, manufacturing cost and time cost of replacement tools. The following combines Figures 1 to 7 , and details of the handle structure and the electronic bronchoscope will be described.

[0060] In one embodiment, a handle structure 100 is as shown Figure 1 and includes a handle end 200, an insertion end 400, a suction valve assembly 500, and an adjustment assembly 600. As an example, the suction valve assembly 500 is used to connect to a suction device and functions as a switch valve to achieve on-off control. The adjustment assembly 600 is used to connect to a target structure to be adjusted, such as a camera device 800, to adjust the direction or position of the target structure, such as adjusting the shooting direction of the camera device 800. The handle end 200 is for holding and operating, and can be connected to other devices through the handle end 200. The insertion end 400 is for inserting into certain target parts. After use, the insertion end 400 is replaced, and the handle end 200 is not inserted into these target parts. With such a structural design, the insertion end 400 can be disassembled and replaced, reducing the risk of cross-infection while meeting the requirement of quick use. And compared with disinfecting the entire instrument of the handle structure 100, disinfecting the insertion end 400 occupies less space, which is beneficial to disinfecting more insertion ends 400 simultaneously or reducing the volume of the disinfection container. In addition, the used insertion end 400 can be directly discarded; or the insertion end housing 410 of the used insertion end 400 can be directly discarded, and the remaining parts of the insertion end 400 can be centrally disinfected.

[0061] Further, a cannula 700 is connected to the insertion end 400, and the illustrated cannula 700 can be only a partial structure. Combining Figure 1 and Figure 2 as shown, in one embodiment, the insertion end 400 or its three-way connection valve 450 is connected to the cannula 700. In a specific product, it can be flexibly set according to actual needs whether the handle structure 100 is provided with a cannula 700 or what kind of cannula 700 it has, etc. The embodiments of the present application do not impose additional restrictions on this.

[0062] Combining Figure 2 and Figure 5 , in one embodiment, the handle structure 100 further includes a sealing ring 300, and the handle end 200 or its handle housing 220 is sealingly connected to the insertion end 400 or its insertion end housing 410 through the sealing ring 300. With such a structural design, it is beneficial to improve the connection sealing performance between the handle end 200 and the insertion end 400 when quickly replacing the insertion end 400.

[0063] Combining Figure 2 and Figure 3, in each embodiment, the adjusting assembly 600 includes a connecting portion 610 and an adjusting portion 620, and the suction valve assembly 500 includes a matching male suction valve connector 510 and a female suction valve connector 520; as an example, the connecting portion 610 and the adjusting portion 620 are detachably connected, that is, the two can be disassembled or connected. Similarly, the male suction valve connector 510 and the female suction valve connector 520 are detachably connected. With such a structural design, in some cases, the connecting portion 610 can be connected to the adjusting portion 620, and the male suction valve connector 510 can be connected to the female suction valve connector 520; in other cases, the connecting portion 610 can be disassembled or split from the adjusting portion 620, and the male suction valve connector 510 can be disassembled from the female suction valve connector 520. With such a structural design, the handle structure 100 has the advantages of simple structure and easy use, achieving pipeline connection and electrical connection while disassembling and replacing, thereby improving the efficiency and reliability of disassembly and replacement.

[0064] Combined together Figure 4 and Figure 5 , the connecting portion 610 and the male suction valve connector 510 are disposed in the handle end 200, and the adjusting portion 620 and the female suction valve connector 520 are disposed in the insertion end 400; the insertion end 400 is detachably connected to the handle end 200, and in the state where the insertion end 400 is connected to the handle end 200, the male suction valve connector 510 is connected to the female suction valve connector 520 to achieve pipeline connection and electrical connection; the connecting portion 610 and the adjusting portion 620 are in meshing engagement, and at least one of the connecting portion 610 and the adjusting portion 620 passes through at least one of the male suction valve connector 510 and the female suction valve connector 520. As an example, the connecting portion 610 passes through the male suction valve connector 510; or the adjusting portion 620 passes through the female suction valve connector 520; or the connecting portion 610 passes through the male suction valve connector 510 and the adjusting portion 620 passes through the female suction valve connector 520.

[0065] Exemplarily, in the state where the insertion end 400 is disassembled from the handle end 200, the connecting portion 610 is disassembled from the adjusting portion 620, and the male suction valve connector 510 is disassembled from the female suction valve connector 520. In this state, the handle end 200, the male suction valve connector 510 and the connecting portion 610 are taken as one part, and the insertion end 400, the female suction valve connector 520 and the adjusting portion 620 are taken as another part. These two parts can be integrally connected and installed together, or integrally disassembled for separate processing.

[0066] In one of the embodiments, as Figure 3As shown, the male connector 510 of the suction valve is provided with a first gear groove 511, a first electrode contact 512, and a first hose connection end 513; the female connector 520 of the suction valve is provided with a second gear groove 521, a second electrode contact 522, and a second hose connection end 523; combined with Figure 4 and Figure 5 , when the insertion end 400 is connected to the handle end 200, the first gear 611 of the connecting portion 610 passes through the first gear groove 511, the second gear 621 of the adjusting portion 620 passes through the second gear groove 521, and the first gear 611 is in meshing engagement with the second gear 621; as an example, such a structural design is beneficial to applying force to structural members such as the imaging device connected to the second gear 621 through meshing engagement, so as to obtain some pose adjustments.

[0067] In this embodiment, the first electrode contact 512 is in contact with the second electrode contact 522 to achieve electrical connection. As an example, when applied to an imaging device, functions such as power supply and / or electrical signal transmission can be realized; the first hose connection end 513 is in communication with the second hose connection end 523 to achieve pipeline connection. As an example, when applied to an endoscope, some fluids can be sucked out through the suction valve.

[0068] In one embodiment, as Figure 2 and Figure 3 shown, the adjusting portion 620 further includes a second wire rope 622, and the second gear 621 is connected to the imaging device 800 through the second wire rope 622; as an example, when the second gear 621 is driven by the first gear 611, the second wire rope 622 is driven to pull the imaging device 800, so that the pose of the imaging device 800 changes, thereby controllably adjusting the shooting angle of the imaging device 800.

[0069] In this embodiment, the connecting portion 610 further includes an adjusting member 613, a first wire rope 612, a winch 614, and a wire rope connection assembly 615 disposed in the handle end 200; the winch 614 is connected to the first gear 611 through the first wire rope 612, and the wire rope connection assembly 615 is disposed on the first wire rope 612 for restricting the travel of the first wire rope 612 on the winch 614; exemplarily, one wire rope connection assembly 615 can be provided, or two wire rope connection assemblies 615 can be provided. The wire rope connection assembly 615 can be penetrated by the first wire rope 612, or attached to the first wire rope 612, or two sections of the first wire rope 612 can be connected through one wire rope connection assembly 615, or three sections of the first wire rope 612 can be connected through two wire rope connection assemblies 615.

[0070] The adjusting member 613 is disposed on the handle end 200 and is connected to the winch 614, and is used to adjust the first gear 611 by adjusting the winch 614, so as to drive the second gear 621 to rotate the imaging device 800 through the second steel wire rope 622. Exemplarily, to ensure the stability of the positional relationship between the steel wire rope and the gear, the first steel wire rope 612 is welded to the first gear 611, and the second steel wire rope 622 is welded to the second gear 621.

[0071] As an example, the adjusting member 613 is an adjusting handle. In a state where a user applies a force, the adjusting member 613 rotates along the handle end 200 or its end housing 210, thereby driving the winch 614 to rotate, and then driving the first gear 611 to rotate through the first steel wire rope 612 and the wire rope connection assembly 615. In this way, the second gear 621 can be driven by the first gear 611 to realize the traction effect on the second steel wire rope 622, which is beneficial to effectively operate the second steel wire rope 622 at the handle end 200. When adjusting the angle of the camera connected to the insertion end 400, it plays a role in connecting and transmitting force, and avoids the insertion end 400 from being unable to be smoothly inserted into the target position due to interference.

[0072] In order to improve the structural strength, in one embodiment, the handle end 200 is provided with an upper support plate 230, and the first gear 611 is rotatably disposed on the upper support plate 230. Exemplarily, a rotating member such as a bearing is provided on the upper support plate 230, and the first gear 611 is rotatably disposed on the rotating member. In the illustrated embodiment, the handle end 200 further includes an end housing 210 and a handle housing 220; the end housing 210 is connected to the handle housing 220, and the upper support plate 230 and the suction valve connector male head 510 are disposed in the handle housing 220; the insertion end 400 or its insertion end housing 410 is detachably connected to the handle housing 220; the suction valve port 560 of the suction valve assembly 500 is disposed on the end housing 210, and sequentially passes through the connecting pipe 570 and the first suction valve hose 540 to be connected to the first hose connection end 513. Exemplarily, in one embodiment, the suction valve port 560 is disposed on the end housing 210 through a suction valve fixing nut 240. Such a structural design is beneficial to quickly and accurately realize the assembly, pipeline connection, and electrical connection between the handle end 200 and the insertion end 400.

[0073] In one embodiment, as Figure 2 and Figure 4 shown, the insertion end 400 includes an insertion end housing 410 and a three-way connection valve 450 disposed in the insertion end housing 410; combined with Figure 5, the adjusting part 620 and the female suction valve connector 520 are arranged in the insertion end housing 410; the suction valve assembly 500 further includes a first suction valve hose 540 arranged in the handle end 200, a suction valve port 560 arranged on the handle end 200, and a second suction valve hose 550 arranged in the insertion end housing 410; one end of the first suction valve hose 540 is connected to the suction valve port 560, and the other end is connected to the first hose connection end 513 of the male suction valve connector 510; one end of the second suction valve hose 550 is connected to the second hose connection end 523 of the female suction valve connector 520, and the other end is connected to the three-way connection valve 450. The three-way connection valve 450 can be connected to other pipelines. As an example, the other pipelines include but are not limited to surgical instruments such as scissors and hemostatic forceps, etc.

[0074] In this embodiment, as Figure 2 and Figure 3 shown, the suction valve assembly 500 further includes a suction channel sealing ring 530. The male suction valve connector 510 is hermetically connected to the female suction valve connector 520 through the suction channel sealing ring 530. Such a structural design is beneficial to improving the connection tightness while enabling the pipeline connection between the male suction valve connector 510 and the female suction valve connector 520 when quickly replacing the insertion end 400.

[0075] In one embodiment, as Figure 2 and Figure 4 shown, the suction valve assembly 500 further includes a connecting pipe 570. One end of the first suction valve hose 540 is connected to the suction valve port 560 through the connecting pipe 570; exemplarily, the connecting pipe 570 is connected to the male suction valve connector 510 through the first suction valve hose 540. The male suction valve connector 510 and the female suction valve connector 520 are inserted into each other, and a suction channel sealing ring 530 is provided at the insertion position to seal the insertion position. The female suction valve connector 520 is connected to the three-way connection valve 450 through the second suction valve hose 550, and the three-way connection valve 450 is connected to the cannula 700. As an example, the three-way connection valve 450 is a forceps channel three-way connection valve. As an example, the connecting pipe 570 is a stainless steel pipe, that is, a suction valve stainless steel pipe. For the male suction valve connector 510, the first hose connection end 513 is relatively rigid, and the connecting pipe 570 is also relatively rigid. The two are connected through the first suction valve hose 540, which is convenient for installation and beneficial to ensuring the relative tightness of the pipeline.

[0076] In one embodiment, the insertion end 400 further includes an insertion end main body 420 and a lower support plate 430 which are connected to each other. The insertion end main body 420 and the lower support plate 430 are both disposed in the insertion end housing 410. The second gear 621 of the adjusting portion 620 is rotatably disposed on the lower support plate 430, and the three-way connection valve 450 is disposed in the insertion end main body 420. Exemplarily, a rotating member such as a bearing is provided on the lower support plate 430, and the second gear 621 is rotatably disposed on the rotating member. As described above, such a structural design is beneficial to improving the structural strength to achieve the transmission of force and avoid failure caused by interference.

[0077] Exemplarily, in one embodiment, as Figure 3 shown, the insertion end 400 further includes a limit fixing screw 460 which is fixed on the lower support plate 430 and is used to limit the positional relationship between the second gear 621 and the lower support plate 430, that is, to ensure that the second gear 621 rotates on the lower support plate 430 and prevent the second gear 621 from loosening from the lower support plate 430 so as to avoid accidents and even injuries. Similarly, another limit fixing screw 460 can be used to be fixed on the upper support plate 230 and is used to limit the positional relationship between the first gear 611 and the upper support plate 230.

[0078] In one embodiment, an electronic bronchoscope 900 as Figure 6 shown includes a camera device 800 and a handle structure 100. The camera device 800 is connected to the insertion end 400 and the adjusting portion 620 of the handle structure 100. The handle structure 100 in the electronic bronchoscope 900 can be selected from any of the embodiments of the handle structure 100. Therefore, the electronic bronchoscope 900 also has the beneficial technical effects of the handle structure 100, which will not be elaborated herein. With such a design, during use, after an electronic bronchoscope 900 surgery or operation is completed and the electronic bronchoscope 900 is used up, only the insertion end 400 of the handle end 200 needs to be quickly replaced, so as to enter the treatment faster, and the handle end 200 does not need to be replaced, thus greatly saving the usage cost, manufacturing cost and time cost of replacing the instrument.

[0079] For example, in one embodiment, the electronic bronchoscope 900 includes a camera device 800 and a handle structure 100, wherein the handle structure 100 includes a handle end 200, an insertion end 400, a suction valve assembly 500 and an adjustment assembly 600; the adjustment assembly 600 includes a connecting portion 610 and an adjustment portion 620, and the suction valve assembly 500 includes a matching suction valve connector male head 510 and a suction valve connector female head 520; the connecting portion 610 and the suction valve connector male head 510 are arranged in the handle end 200, and the adjustment portion 620 and the suction valve assembly 500 include a matching suction valve connector male head 510 and a suction valve connector female head 520. The female valve connector 520 is disposed in the insertion end 400; the insertion end 400 is detachably connected to the handle end 200, and when the insertion end 400 is connected to the handle end 200, the male suction valve connector 510 is connected to the female suction valve connector 520 to achieve pipeline communication and conductive connection; the connecting portion 610 and the adjusting portion 620 are toothed, and at least one of the connecting portion 610 and the adjusting portion 620 passes through at least one of the male suction valve connector 510 and the female suction valve connector 520. The rest of the embodiments are similar and will not be described in detail.

[0080] Next, continue to combine Figures 1 to 7 , the handle structure 100 and the electronic bronchoscope 900 are illustrated. The handle structure 100 includes a handle end 200, an insertion end 400, a suction valve assembly 500 and an adjustment assembly 600. In this embodiment, by splitting the traditional integrated handle into the handle end 200 and the insertion end 400, the adjustment assembly 600 is provided with a first gear 611 and a second gear 621 as upper and lower gears, which are respectively mounted on the upper support plate 230 of the handle end 200 and the lower support plate 430 of the insertion end 400, and are respectively fixed by limit fixing screws 460.

[0081] When in use, the handle end 200 and the insertion end 400 are directly plugged in, and the sealing ring 300 is filled in the insertion end 400, and after the plugging is completed, it can be connected by snap-fit. For the handle end 200 and the insertion end 400 with snap-fit ​​connection, the snap-fit ​​and the undercut need to be aligned before insertion, and the connection part 610 installed on the handle end 200, such as the adjustment handle, should be on the end shell 210, and the insertion end 400 should be kept in the same straight line with the handle shell 220 of the handle end 200 when inserted, that is, aligned by the axis.

[0082] When the handle end 200 and the insertion end 400 are plugged together, the male connector 510 of the suction valve connector and the female connector 520 of the suction valve connector cooperate with each other. When they are in cooperation, an insertion fit is formed at the upper and lower interfaces of the suction valve, that is, the first hose connection end 513 and the second hose connection end 523 form an insertion fit. There is a suction channel sealing ring 530 at the mating part to prevent water leakage. There is also a suction valve port 560 connected to the first suction valve hose 540 through a connecting pipe 570 to play a guiding role, and is connected to the male connector 510 of the suction valve connector through the first suction valve hose 540. The female connector 520 of the suction valve connector at the insertion end 400 is connected to the second suction valve hose 550 through the second hose connection end 523 and finally connected to the three-way connection valve 450. Such a connection enables the wire rope connection assembly 615 at the handle end 200 to adjust the second wire rope 622 by adjusting the first wire rope 612, thereby achieving the effect of adjusting the deflection of the imaging device 800 on the cannula 700 connected to the insertion end 400, as Figure 7 shown. Among them, the imaging signal of the imaging device 800 connected to the insertion end 400 is transmitted into the handle end 200 through the conductive connection between the male connector 510 of the suction valve connector and the female connector 520 of the suction valve connector. In this embodiment, the first gear 611 and the second gear 621 are equivalent to fixed pulleys and play a role in force transmission. The male connector 510 of the suction valve connector and the female connector 520 of the suction valve connector play a role in signal transmission, and also play a role in fluid suction and derivation through pipeline connection.

[0083] In this embodiment, the upper support plate 230 is connected to the end housing 210 or the handle housing 220, the lower support plate 430 is connected to the insertion end main body 420, and the first gear 611 is welded to the first wire rope 612, and the second gear 621 is welded to the second wire rope 622. When the first wire rope 612 is connected to the winch 614, the wire rope connection assembly 615 is required to limit the extreme position of the first wire rope 612 when its position changes to protect the imaging device 800 and make it have a certain stability.

[0084] The upper support plate 230 is connected to the handle housing 220 by screws, the lower support plate 430 is connected to the insertion end main body 420, the male connector 510 of the suction valve connector, that is, the male head seat, is installed on the handle housing 220, and the female connector 520 of the suction valve connector, that is, the female head seat, is installed on the insertion end housing 410, which can be fixed by glue or by snap. In contrast, the traditional design uses four transmission lines to transmit the image of the insertion end 400 to the host through the handle end 200. However, since the insertion end 400 and the handle end 200 are detachable, in the connected state, the male connector 510 of the suction valve connector and the female connector 520 of the suction valve connector are required to achieve signal transmission at the connection position. In this embodiment, it is achieved by the contact between the first electrode contact 512 of the male connector 510 of the suction valve connector and the second electrode contact 522 of the female connector 520 of the suction valve connector.

[0085] When the handle end 200 or its handle housing 220 is inserted into the insertion end 400, such as the insertion end housing 410, the two gears, the first gear 611 and the second gear 621, will mesh, because if they do not mesh, interference will occur, resulting in the insertion end 400 being unable to be smoothly inserted into the handle end 200. When the handle end 200 adjusts the angle of the camera connected to the second wire rope 622 in the insertion end 400 through the first wire rope 612, the two gears play a role in connecting and transmitting force.

[0086] After use, the entire insertion end 400 is removed and directly discarded. The handle end 200 is connected to a new insertion end 400, and then the operation is continued for the next patient. With such a structural design, the handle structure 100 has a simple structure, does not require a complex assembly method for connection, and is convenient to disassemble during use; it can achieve rapid replacement of structures such as the insertion end 400, enter the treatment faster, and there is no need to disinfect the handle end 200 during the operation. The new or disinfected insertion end 400 and other structures can be directly replaced, thus preventing cross-infection. And because the handle end 200 can be retained, the use cost and manufacturing cost are greatly saved.

[0087] It should be noted that other embodiments of the present application also include the handle structure and the electronic bronchoscope that can be implemented formed by the combination of the technical features in the above embodiments.

[0088] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combinations of these technical features do not conflict, they should be considered to be within the scope described in this specification.

[0089] The above-described embodiments only represent several implementation manners of the present application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
