Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a reusable bronchoscope handle. Background Technology

[0002] An endoscope is a medical device that integrates traditional optics, ergonomics, precision mechanics, modern electronics, mathematics, and software. It features an image sensor, optical lens, light source, and mechanical components. It can be inserted into the stomach through the mouth or other natural orifices to examine diseased tissues. Furthermore, endoscopes can visualize lesions that are invisible to X-rays. Therefore, endoscopes are extremely helpful in doctors' daily work; for example, they allow doctors to observe ulcers or tumors in the stomach and develop the best treatment plan accordingly.

[0003] Existing endoscope handles typically consist of a housing, a drive assembly installed within the housing, and an insertion tube installed at the end of the housing. For example, Chinese utility model patent CN221469815U, entitled "An Endoscope Self-Locking Handle and Endoscope," includes a housing and a drive assembly. The housing has gear patterns on at least one inner wall. The drive assembly includes a lever and a drive wheel, with the drive wheel rotatably mounted within the housing. The lever is connected to the drive wheel, and the controllable portion of the lever is located outside the housing. Furthermore, according to its specification... Figure 1 It can be seen that the pull rod is located at the junction of the two housings. The junction of the two housings has a housing hole for the pull rod to move back and forth. A protrusion is provided on one side of the drive wheel, and the protrusion meshes with the gear pattern on the corresponding side of the housing.

[0004] The drive assembly and the housing are engaged by gear grooves and protrusions. When the drive wheel is stationary, the protrusions are embedded in the gear grooves of the housing to form a self-locking mechanism, which limits the position of the drive wheel. When an external force is applied to the lever to push the drive wheel to rotate radially, the resistance between the protrusions and the gear grooves needs to be overcome so that the protrusions are pushed out of the gear grooves, thereby unlocking the drive wheel from the housing.

[0005] However, the existing technology still has the following drawbacks: the existing endoscope handle requires a shell hole to be made at the junction of the two housings to allow the lever to be pulled radially back and forth. Since the endoscope handle is easily wetted during actual testing, making a shell hole on the housing will reduce the waterproof effect of the endoscope handle and affect its service life; moreover, it increases the cleanliness, causing the existing endoscope handle to be discarded after only one use, which not only wastes resources but also increases medical costs. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a reusable bronchoscope handle.

[0007] The purpose of this utility model is achieved by the following technical solution: a reusable bronchoscope handle, comprising a first housing, a second housing, and a rotating mechanism. The first housing and the second housing are fitted together to form a handle cavity, and an insertion tube is provided at the end of the handle cavity. The rotating mechanism has a rotating wheel and an axial pull switch disposed along the axis of the rotating wheel. The rotating wheel is disposed within the handle cavity, and the axial pull switch is disposed outside the first housing and / or the second housing. The rotating wheel rotates axially and is connected via a traction line, which drives the insertion tube to swing.

[0008] Furthermore, the output shaft of the rotating wheel extends from the side of the first housing and / or the second housing and is connected to the axial toggle switch.

[0009] Furthermore, a sealing element is provided in the extended direction at the junction of the first housing and the second housing.

[0010] Furthermore, the first housing and the second housing are respectively provided with a covering edge at the connection point where they cover each other. The first housing has a plurality of snap-fit ​​grooves along the extension direction of the covering edge, and the second housing has a plurality of protruding snap-fit ​​protrusions along the extension direction of the covering edge. The second housing is snapped into the snap-fit ​​grooves by the snap-fit ​​protrusions to cover and connect with the first housing.

[0011] Furthermore, a first partition plate is provided on the inner side of the first housing, and a second partition plate is provided on the inner side of the second housing. Both the first partition plate and the second partition plate are arranged along the extension direction of the bronchoscope handle. A partition positioning port is provided on the outer side of the second partition plate so that when the second housing is closed and connected with the first housing, the outer side of the first partition plate is fitted into the partition positioning port of the second partition plate.

[0012] Furthermore, the first housing and the second housing are connected by an inlet valve pipe and a drain assembly that communicate with the handle cavity. The inlet valve pipe has an inlet and a first outlet, and the drain assembly has an inlet and a drain pipe. The first outlet is connected to the inlet through a drain pipe, and the drain pipe is arranged on one side of the first partition plate and the second partition plate.

[0013] Furthermore, the inlet valve tube has a second outlet and is connected to the insertion tube through the second outlet.

[0014] Furthermore, the drainage assembly has a drainage control key for controlling whether the inlet is connected to or disconnected from the drainage pipe.

[0015] Furthermore, the inner side of the first housing is provided with a plurality of wiring seats for positioning and arranging the traction wire. The plurality of wiring seats are arranged along the extension direction of the bronchoscope handle and are located on one side of the first partition plate and the second partition plate.

[0016] Furthermore, the connecting pipe end is located at one end of the handle cavity, and the other end of the handle cavity is provided with an electrical connection end; the control circuit board located in the handle cavity is electrically connected to the wire connected to the electrical connection end, and the control circuit board is arranged to be isolated from the rotating wheel through the first partition plate and the second partition plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This embodiment of the application improves the overall waterproofing of the bronchial endoscope handle by having the output shaft of the rotating wheel protrude from the outer side of the housing and by mounting an axial pull switch on the outer surface of the housing and fixing it to the output shaft of the rotating wheel. This allows the rotating wheel to rotate axially and the insertion tube to swing by operating the axial pull switch. Compared with the previous method of opening shell holes at the junction of the two housing parts of the endoscope handle to allow the pull rod to move radially back and forth, this embodiment of the application eliminates the need to open shell holes on the sides of the two housing parts, thereby improving the overall waterproofing of the bronchial endoscope handle, increasing its service life, making cleaning more convenient, and allowing the bronchial endoscope handle to be reused multiple times, saving resources and reducing medical costs.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0031] like Figure 1-4 As shown, a reusable bronchoscope handle can be inserted into the stomach through the mouth or into the body through other natural orifices to detect diseased tissues, and the endoscope can be used to see lesions that cannot be seen by X-rays.

[0032] The reusable bronchoscope handle includes a first housing 10, a second housing 11, and a rotating mechanism 20. In use, the first housing 10 and the second housing 11 are connected to each other and covered. After the connection is made, the interior of the first housing 10 and the second housing 11 forms the handle cavity 14. The middle part of the first housing 10 and the second housing 11 is the grip part 13. The surface of the grip part 13 is provided with an ergonomically designed fingerprint recess.

[0033] More specifically, a covering edge 12 is provided at the junction of the first housing 10 and the second housing 11, and the covering edge 12 extends along the edges of the first housing 10 and the second housing 11.

[0034] The cover edge 12 of the first housing 10 is formed by its inner surface being concave outward along the edge of the housing, and the cover edge 12 of the second housing 11 is formed by its outer surface being concave inward along the edge of the housing. Therefore, the thickness of the cover edge is thinner than the thickness of the housing, and the cover edge 12 is stepped with respect to the edges of the first housing 10 and the second housing 11. When assembling the housing, the cover edge 12 of the first housing 10 covers the outer surface of the cover edge 12 of the second housing 11, thereby making the outer surfaces of the first housing 10 and the second housing 11 fit more tightly, reducing the gap and improving the overall aesthetics of the bronchoscope handle.

[0035] Furthermore, the first housing 10 has several locking grooves 121 extending along its cover edge 12, and the second housing 11 has several protruding locking protrusions 122 extending along its cover edge 12. During assembly, the second housing 11 is secured in the locking grooves 121 by the locking protrusions 122, thus ensuring a more secure connection between the second housing 11 and the first housing 10. Simultaneously, the cooperation of the cover edges 12 between the first housing 10 and the second housing 11, and the positioning assembly between the locking protrusions 122 and the locking grooves 121, improves the ease of assembly of the bronchoscope handle.

[0036] After the first housing 10 and the second housing 11 are connected and covered, the two ends of the resulting handle cavity 14 are respectively configured as an electrical connection end 142 and a connecting end 141. The electrical connection end 142 is used to electrically connect to an external power source, and the wire of the electrical connection end 142 is electrically connected to the control circuit board 70 provided inside the handle cavity 14. The connecting end 141 is used to install the insertion tube 30. During detection and treatment, the insertion tube 30 can enter the stomach through the mouth or enter the body through other natural orifices to detect diseased tissue.

[0037] Preferably, the rotating mechanism 20 has a rotating wheel 201 and an axial toggle switch 202. The rotating wheel 201 is installed inside the handle cavity 14 and is movably assembled with a wheel seat inside the first housing 10. The output shaft of the rotating wheel 201 extends out from the side of the first housing 10 and / or the second housing 11. In this embodiment, the output shaft of the rotating wheel 201 extends out from the second housing 11. Then, in this embodiment, the axial toggle switch 202 is installed on the outer surface of the second housing 11 and fixedly connected to the output shaft of the rotating wheel 201, thereby achieving the purpose of installing the axial toggle switch 202 in the axial direction of the rotating wheel 201. By operating the controllable end of the axial toggle switch 202, the rotating wheel 201 can be controlled to rotate axially in the handle cavity 14.

[0038] The rotating wheel 201 has a winding groove 2011 around its circumference for winding the traction line. The rotating wheel 201 is connected to the insertion tube 30 installed on the handle cavity 14 through the traction line. When the rotating wheel 201 is controlled to rotate axially, the insertion tube 30 can be driven to swing back and forth through the traction line (not shown in the figure) to facilitate the detection of organs and tissues in different positions in the body.

[0039] By extending the output shaft of the rotating wheel 201 through the outer side of the housing, and by mounting the axial pull switch 202 on the outer surface of the housing and fixing it to the output shaft of the rotating wheel 201, the rotating wheel 201 can be driven to rotate axially and the insertion tube 30 can be swung by manipulating the axial pull switch 202. Compared with the previous implementation method of opening shell holes at the junction of the two housings of the endoscope handle to allow the pull rod to move radially back and forth, the embodiment of this application can eliminate the need to open shell holes on the sides of the two housings, thereby improving the overall waterproof effect of the bronchial endoscope handle, increasing its service life, and making cleaning more convenient. The bronchial endoscope handle can be reused multiple times, saving resources and reducing medical costs.

[0040] Preferably, a sealing element 60 is provided in the extended direction of the junction where the first housing 10 and the second housing 11 overlap. The sealing element 60 can be made of sealant, sealing strip or sealing gasket. By attaching and filling the junction where the first housing 10 and the second housing 11 overlap, the sealing performance between the first housing 10 and the second housing 11 is further improved, and the waterproof effect is better.

[0041] Preferably, a first partition plate 101 is provided on the inner side of the first housing 10, and a second partition plate 111 is provided on the inner side of the second housing 11. Typically, the width of the second partition plate 111 is wider than that of the first partition plate 101. Both the first partition plate 101 and the second partition plate 111 are arranged along the extension direction of the bronchoscope handle.

[0042] The outer side of the second partition plate 111 is provided with a partition positioning port 1111. The partition positioning port 1111 is a stepped partition positioning port 1111 that is roughly made by thinning the outer side of the second partition plate 111. Therefore, when the second housing 11 is closed and connected with the first housing 10, the outer side of the first partition plate 101 can be fitted with the partition positioning port 1111 of the second partition plate 111, so that the first partition plate 101 and the second partition plate 111 can be accurately and quickly matched. Moreover, after the first partition plate 101 and the second partition plate 111 are matched, the handle cavity 14 can be divided into two cavities.

[0043] A liquid inlet valve pipe 40 and a liquid drain assembly 50 are provided on the side where the first housing 10 and the second housing 11 overlap and connect. The liquid inlet valve pipe 40 has a liquid inlet 401, a first liquid outlet 402 and a second liquid outlet 403. The liquid drain assembly 50 has a liquid inlet 501, a liquid drain pipe 502 and a liquid drain control key 503. The first liquid outlet 402 and the second liquid outlet 403 of the liquid inlet valve pipe 40 extend into the handle cavity 14. The liquid inlet 401 is exposed on the surface of the housing and is used to input liquid. The first liquid outlet 402 is used to connect with the insertion tube 30. The liquid inlet 501 of the liquid drain assembly 50 extends into the handle cavity 14. The liquid drain pipe 502 and the liquid drain control key 503 are exposed on the surface of the housing. The second liquid outlet 403 is connected to the liquid inlet 501 through the liquid drain pipe 504. By pressing the liquid drain control key 503, the connection or disconnection between the liquid inlet 501 and the liquid drain pipe 502 can be controlled.

[0044] In this embodiment, the drain pipe 504 can be arranged on one side of the first partition plate 101 and the second partition plate 111. The first partition plate 101 and the second partition plate 111 separate and support the drain pipe 502, thereby improving the assembly stability of the drain pipe 504 in the handle cavity 14. This avoids the problem of leakage caused by the drain pipe 504 shaking randomly during daily use, which could lead to it detaching from the second outlet 403 and the inlet 501.

[0045] Preferably, the inner side of the first housing 10 is also provided with a plurality of wiring seats 102. The plurality of wiring seats 102 are arranged along the extension direction of the bronchoscope handle, and the plurality of wiring seats 102 are located on the side of the first partition plate 101 and the second partition plate 111 away from the drainage pipe 504. In this way, the drainage pipe 504 and the wiring seats 102 are separated by the partition plate, thereby avoiding interference between the drainage pipe 504 and the traction line when the bronchoscope handle is used daily.

[0046] The wiring base 102 has a limiting slot 1021. When arranging the traction wire in the handle cavity 14, the traction wire can be clamped in the limiting slot 1021 of the wiring base 102, so that multiple traction wires are arranged in an orderly manner in the handle cavity 14, making the inside of the handle cavity 14 neater.

[0047] The control circuit board 70 inside the handle cavity 14 is also arranged on one side of the first partition plate 101 and the second partition plate 111. The partition plates separate the control circuit board 70 from the rotating wheel 201, preventing the rotation of the rotating wheel 201 from interfering with the control circuit board 70. The control circuit board 70 has at least a power module and a button module for electrically connecting to the function buttons 80. In this embodiment, the electrical control includes at least circuit control for providing a light source.

[0048] Therefore, by setting a partition plate in the first housing 10 and the second housing 11, the orderly and reasonable assembly between the drain pipe 504, the traction line and the control circuit board 70 can be improved, as well as the structural strength and assembly stability of the housing can be improved.

[0049] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
