Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an endoscope handle with a normalized leak detection port and power connection port. Background Technology

[0002] An endoscope is a medical device that integrates traditional optics, ergonomics, precision mechanics, modern electronics, mathematics, and software. It contains image sensors, optical lenses, light sources, and mechanical devices. It can be inserted into the stomach through the mouth or other body orifices to examine diseased tissues. Furthermore, endoscopes can visualize lesions that are not visible to X-rays. Therefore, endoscopes are extremely helpful to doctors in their daily work. For example, with the help of an endoscope, doctors can observe ulcers or tumors in the stomach and formulate the best treatment plan accordingly.

[0003] Existing endoscope handles typically have a handle housing, which is usually composed of two housings that fit together. For example, Chinese invention patent application CN111803007A, entitled "An Endoscope Handle and Endoscope," includes a handle housing and a control mechanism disposed within the handle housing. The handle housing includes a fixed part and a gripping part that communicate with each other. The fixed part has a front through hole and a rear through hole at its front and rear ends, respectively. The front and rear through holes on the fixed part are used to pass through the working channel. The rear through hole is unobstructed, facilitating operation and instrument entry into the working channel. The gripping part has a cable outlet for connecting cables, optical cables, and other electrical equipment. Furthermore, the control mechanism includes a control wheel that controls the bending of the tip of the working channel. The control wheel is disposed within the gripping part, with a portion of the control wheel located outside the control part, allowing the user to operate the control wheel with one hand. Operating the control wheel controls the bending of the tip of the working channel in a plane, adjusting the bending angle of the tip.

[0004] However, the existing technology still has the following drawbacks:

[0005] 1. The existing endoscope handle has its cable outlet located on one side of the grip, while the rear through-hole for operation and instrument entry is located on the fixing part. This means that the cable outlet and the rear through-hole are located on opposite sides of the handle housing. The cable outlet can only be used to connect the wire, and the rear through-hole can only be used for instrument entry. Therefore, each interface and end hole has a single function, which undoubtedly increases the structural complexity of the endoscope handle and the cost of mold production. In addition, it is impossible to detect air leakage in the inner cavity of the handle housing through its interfaces or end holes, which cannot guarantee the sealing of the endoscope handle. It is easy to get wet during use, and it is impossible to disinfect, clean and reuse the endoscope handle. It is discarded after only one use, resulting in resource waste and high cost.

[0006] 2. Existing endoscope handles require opening shell holes at the junction of the two housings to allow the control wheel to protrude outside the handle housing for easy radial reciprocating movement. Due to the opening of shell holes, the sealing effect of the endoscope handle is reduced. Utility Model Content

[0007] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an endoscope handle with a normalized leak detection port and power connection port.

[0008] The purpose of this utility model is achieved by the following technical solution: an endoscope handle with a normalized leak detection port and power connection port, comprising a first housing, a second housing, and a pneumatic-electric connection assembly. The first housing and the second housing are covered and connected to form a handle cavity. The left and right ends of the handle cavity are respectively provided with a pneumatic-electric functional end and a connecting end for installing an insertion tube. The pneumatic-electric connection assembly has a data connector and a sealing adapter. The data connector is located inside the pneumatic-electric functional end and is electrically connected to an external power source and a control circuit board inside the handle cavity. The sealing adapter is detachably and sealingly connected to the outside of the pneumatic-electric functional end for connecting a leak detection device and injecting gas supplied by the leak detection device into the handle cavity.

[0009] Furthermore, the sealing adapter has a leak test connector and a connector sleeve, the leak test connector is disposed inside the connector sleeve, and the leak test connector is elastically connected to the air inlet of the connector sleeve.

[0010] Furthermore, the connector sleeve is connected to the leak detection device, and the leak detection connector is pushed by the connector head of the leak detection device, causing it to compress the elastic element and separate from the air inlet of the connector sleeve.

[0011] Furthermore, the pneumatic-electric functional end has an external thread, and one end of the connector sleeve has an internal thread and is threadedly connected to the external thread of the pneumatic-electric functional end through the internal thread.

[0012] Furthermore, the endoscope handle also includes a rotating mechanism, which has a rotating wheel and an axial pull switch disposed along the axis of the rotating wheel. The rotating wheel is disposed in 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 to a traction line, thereby causing the insertion tube to swing.

[0013] Furthermore, a sealing element is provided in the extended direction at the junction of the first housing and the second housing.

[0014] 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.

[0015] 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 with the partition positioning port of the second partition plate.

[0016] 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.

[0017] Furthermore, the first housing and the second housing are connected by an inlet valve pipe and a drain assembly on the side that are connected to the handle cavity. The inlet valve pipe has an inlet, a first outlet and a second outlet. 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. The inlet valve pipe is connected to the insertion pipe through the second outlet.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] (1) In this embodiment of the application, the first housing and the second housing are connected to form a handle cavity, and a pneumatic-electric functional terminal is provided at one end of the handle cavity. A pneumatic-electric connection component is provided at the pneumatic-electric functional terminal so as to electrically connect an external power supply and a control circuit board through the data connector provided inside the pneumatic-electric functional terminal, so as to provide power to the endoscope handle and realize the purpose of the pneumatic-electric functional terminal as a power interface. In addition, a leak detection device is connected through a sealing adapter provided outside the pneumatic-electric functional terminal by the pneumatic-electric connection component so as to inject the gas provided by the leak detection device into the handle cavity and perform leak detection, thereby determining whether the handle cavity and its internal pipes are leaking and sealed, thus realizing the purpose of the pneumatic-electric functional terminal as a leak detection port.

[0020] Compared to previous implementations that involved setting power cable outlets on both sides of the endoscope handle and rear through-holes for operation and instrument entry, this embodiment of the application standardizes the power inlet and leak detection outlet at one end of the handle cavity. This simplifies the endoscope handle structure, reduces mold opening costs, and lowers production and processing costs. By sealing the adapter and the pneumatic and electrical functional end, the sealing performance of the endoscope handle cavity is improved. The endoscope handle can be disinfected, cleaned, and reused, saving resources, reducing medical costs, and facilitating market promotion.

[0021] (2) A rotating mechanism is provided inside the endoscope handle, and the output shaft of the rotating wheel of the rotating mechanism passes through the outer side of the housing. An axial pull switch is assembled on the outer surface of the housing and fixedly connected to the output shaft of the rotating wheel, so as to drive the rotating wheel to rotate axially and drive the insertion tube to swing by operating the axial pull switch. Compared with the previous endoscope handle, which opened a shell hole at the junction of the two housings to allow the pull rod to move radially back and forth, the embodiment of this application can eliminate the need to open a shell hole on the side 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, further saving resources and reducing medical costs. Attached Figure Description

[0038] 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.

[0039] like Figures 1-8 As shown, an endoscope handle with a normalized leak detection port and power connection port can be inserted into the stomach through the mouth or into the body through other natural orifices to detect lesions. Moreover, the endoscope can be used to see lesions that cannot be detected by X-rays.

[0040] The endoscope handle with the leak detection port and power connection port normalized includes a first housing 10, a second housing 11, a rotating mechanism 20, and a pneumatic-electric connection assembly 60. 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] After the first housing 10 and the second housing 11 are connected and fitted together, the two ends of the resulting handle cavity 14 are respectively configured as an electric / pneumatic functional end 142 and a connecting pipe end 141. The electric / pneumatic functional end 142 is used to electrically connect to an external power source and a control circuit board 80 installed inside the handle cavity 14. In addition, the electric / pneumatic functional end 142 is also used to connect to a leak detection device. The leak detection device adopts existing detection equipment, which will not be described in detail here. The connecting pipe end 141 is used to install an insertion tube 30. During detection and treatment, the insertion tube 30 can enter the stomach through the mouth or other natural orifices to detect diseased tissue.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] Preferably, a sealing element 70 is provided in the extended direction at the junction of the first housing 10 and the second housing 11. The sealing element 70 can be made of sealant, sealing strip or sealing gasket. By attaching and filling the junction of the first housing 10 and the second housing 11 with the sealing element 70, the connection sealing between the first housing 10 and the second housing 11 is further improved, and the waterproof effect is better.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] The control circuit board 80 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 80 from the rotating wheel 201, preventing the rotation of the rotating wheel 201 from interfering with the control circuit board 80. The control circuit board 80 has at least a power module and a button module for electrically connecting function buttons 90. In this embodiment, the electrical control includes at least circuit control for providing a light source.

[0056] 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 80 can be improved, as well as the structural strength and assembly stability of the housing can be improved.

[0057] Preferably, the pneumatic-electric connection assembly 60 has a data connector 601 and a sealing adapter 602, the sealing adapter 602 including a leak test connector 6021, an elastic element 6023 and a connector sleeve 6022.

[0058] In practical use, the pneumatic-electric functional end 142 of the handle cavity 14 has an end hole. The data connector 601 is installed in the handle cavity 14 and the end hole of the pneumatic-electric functional end 142. Furthermore, the data connector 601 is fixedly connected to the mounting plate inside the handle cavity 14, making its installation within the handle cavity 14 more stable. The data connector 601 is also electrically connected to the control circuit board 80 inside the handle cavity 14. Therefore, when the endoscope handle is used for endoscopic surgery, the data connector 601 on the pneumatic-electric functional end 142 can be used to electrically connect to an external power source to provide power to the endoscope handle. In addition, the data connector 601 can also be used to electrically connect the endoscope camera of the endoscope handle to the main unit. Therefore, by setting the data connector 601 on the pneumatic-electric functional end 142 of the handle cavity 14, the pneumatic-electric functional end serves as a power interface.

[0059] Additionally, the connector sleeve 6022 is primarily used for connection with leak detection equipment, so the endoscope handle does not require the connector sleeve during endoscopic surgery. An external thread is provided on the outer circumference of the end hole of the pneumatic / electrical functional end 142, one end of the connector sleeve 6022 has an internal thread, and the other end of the connector sleeve 6022 has an air inlet 60221. When installing the connector sleeve 6022, the internally threaded end of the connector sleeve 6022 is detachably threaded to the pneumatic / electrical functional end 142 to facilitate the disassembly, assembly, and replacement of the connector sleeve 6022.

[0060] Leak test connector 6021 is installed inside connector sleeve 6022. Therefore, when installing connector sleeve 6022 at the pneumatic and electrical function terminal 142, leak test connector 6021 is first installed inside connector sleeve 6022. Leak test connector 6021 has a cylindrical strip, an assembly head provided at one end of the cylindrical strip, and a sealing ring provided on the cylindrical strip. Furthermore, elastic element 6023 is sleeved on the cylindrical strip. Elastic element 6023 can be a telescopic spring. When installing the leak test connector 6021, align the assembly head of one end of the leak test connector 6021 with the internal thread end of the connector sleeve 6022, and insert the other end of the leak test connector 6021 into the air inlet 60221 of the connector sleeve 6022. Under the elastic action of the elastic element 6023, the cylindrical strip of the leak test connector 6021 is always inserted into the air inlet 60221 of the connector sleeve 6022, and the sealing ring seals and presses the inside of the air inlet 60221, thereby making the connector sleeve 6022 and the pneumatic and electrical functional end 142 of the handle cavity 14 sealed together.

[0061] When a leak detection device is connected to the connector sleeve 6022, the connector of the leak detection device will push against the cylindrical strip of the leak detection connector 6021, causing the cylindrical strip to slide towards the data connector. Furthermore, the sealing ring on the cylindrical strip compresses the elastic element 6023, causing the cylindrical strip and its sealing ring to separate from the air inlet 60221 of the connector sleeve 6022. This allows the gas supplied by the leak detection device to enter the handle cavity 14 through the air inlet 60221 of the connector sleeve 6022 and the pneumatic-electric functional terminal 142. After a certain amount of gas is injected into the handle cavity 14, the leak detection device will also monitor the air pressure in the handle cavity 14 in real time, thereby determining whether the handle cavity 14 and its internal pipes are leaking and whether they are airtight. Therefore, by setting a sealing adapter 602 at the pneumatic-electric functional terminal 142 of the handle cavity 14, the pneumatic-electric functional terminal 142 serves as a leak detection port.

[0062] Furthermore, when disinfecting and cleaning the endoscope handle, the sealing adapter 602 also needs to be installed on the pneumatic and electrical function terminal 142. Since no leak detection equipment is connected at this time, the side-leakage connector, under the elastic action of the elastic member 6023, can seal and press the air inlet 60221 of the connector outer sleeve 6022 through the sealing ring on its cylindrical strip to avoid leaks. Therefore, the endoscope handle of this embodiment, after being equipped with the sealing adapter 602, can be reused multiple times after disinfection and cleaning, saving resources and reducing medical costs.

[0063] Thus, the first housing 10 and the second housing 11 are connected to form the handle cavity 14, and a pneumatic-electric functional terminal 142 is provided at one end of the handle cavity 14. A pneumatic-electric connection component 60 is provided at the pneumatic-electric functional terminal 142, so as to electrically connect an external power supply and a control circuit board through a data connector 601 provided inside the pneumatic-electric functional terminal 142, so as to provide power to the endoscope handle and realize the purpose of the pneumatic-electric functional terminal 142 as a power interface. In addition, a leak detection device is connected to the sealing adapter 602 provided outside the pneumatic-electric functional terminal 142 through the pneumatic-electric connection component 60, so as to inject the gas provided by the leak detection device into the handle cavity 14 and perform leak detection, thereby determining whether the handle cavity 14 and its internal pipes are leaking and sealed, thus realizing the purpose of the pneumatic-electric functional terminal 142 as a leak detection port. Compared to previous implementations that involved setting power cable outlets and rear through-holes for control and instrument entry on both sides of the endoscope handle, this embodiment of the application normalizes the power inlet and leak detection outlet at one end of the handle cavity 14. This simplifies the structure of the endoscope handle, reduces mold opening costs, and lowers production and processing costs. The sealing performance of the endoscope handle cavity 14 is improved through the sealed connection between the sealing adapter 602 and the pneumatic and electrical functional end 142. The endoscope handle can be disinfected, cleaned, and reused, saving resources, reducing medical costs, and facilitating market promotion.

[0064] 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.
