DETAILED DESCRIPTION

[0037] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the following will combine the drawings in the embodiments of the present application to clearly and completely describe the technical scheme in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, not all embodiments. The components of the embodiments of the present application described and shown in the drawings can be arranged and designed in various different configurations.

[0038] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are intended to fall within the scope of protection of the present invention.

[0039] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0040] In the description of the present invention, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, or is the orientation or position relationship in which the utility model product is usually placed when in use. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0041] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0042] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.

[0043] In the prior art, in order to realize the multiple functions of an endoscope, the endoscope handle is integrated with multiple parts. The multiple parts are assembled inside the handle, which is cumbersome, time-consuming and labor-intensive. In addition, the multiple parts are processed separately, which increases the manufacturing cost.

[0044] In view of this, the designer provides an endoscope handle that integrates multiple components with the handle body 100, that is, multiple components are integrated with the handle body 100, so that the functions of the handle body 100 are diversified, the tedious assembly process is eliminated, and processing and manufacturing are facilitated.

[0045] Please combine Figure 1-Figure 3 In this embodiment, the endoscope handle includes a handle body 100, and the interior of the handle body 100 is provided with a first flow channel 121, a second flow channel 122, a cable channel 123 and an installation chamber 124. One of the first flow channel 121 and the second flow channel 122 is used to connect to the water inlet pipe, and the other of the two is used to connect to the water outlet pipe; the cable channel 123 is used for passing the cable body connected to the image collector 002; the installation chamber 124 is used to accommodate the circuit board.

[0046] As described above, the endoscope handle provided in this embodiment is used as follows:

[0047] By forming a first flow channel 121, a second flow channel 122, a cable channel 123, and an installation chamber 124 within the handle body 100, during use, the insertion tube 001 is directly plugged into the handle body 100 or integrally molded therewith. The first lumen 011 of the insertion tube 001 communicates with the first flow channel 121 of the handle body 100, and the second lumen 012 of the insertion tube 001 communicates with the second flow channel 122 of the handle body 100. Furthermore, the liquid inlet pipe is directly connected to the first flow channel 121, and the liquid outlet pipe is directly connected to the second flow channel 122. Liquid can enter the body through the first flow channel 121 and then be discharged through the second flow channel 122. This eliminates the need for a separate piping structure inside the handle body 100 that connects to the insertion tube 001, as well as piping structures inside the handle body 100 that connect to the liquid inlet and outlet pipes. This eliminates some components, simplifies assembly steps, and reduces assembly difficulty, saving time and effort and increasing assembly efficiency. Furthermore, the cable body is threaded through the cable channel 123, and the circuit board is mounted within the mounting chamber 124 of the handle body 100, resulting in a compact and small overall structure.

[0048] The following embodiments illustrate the detailed structure of the endoscope handle of the present application by way of examples.

[0049] Please combine Figure 1 In this embodiment, the handle body 100 optionally includes an integrated head 110 and a gripping portion 120. The extension directions of the head 110 and the gripping portion 120 form an angle, which can be an obtuse angle. When in use, the operator can hold the gripping portion 120, which is convenient and flexible to operate.

[0050] Specifically, the head 110 has a first end 101 and a second end 102 along its length. A collecting channel 111 and an instrument access channel 112 may be provided within the head 110. One end of the collecting channel 111 extends to the first end 101, while one end of the instrument access channel 112 extends to the second end 102. A first annular limiting surface 113 is provided on the inner circumferential wall of the collecting channel 111. The first annular limiting surface 113 is located on the side of the first flow channel 121 closer to the first end 101. A second annular limiting surface 114 is provided on the inner circumferential wall of the instrument access channel 112. The second annular limiting surface 114 is located on the side of the second flow channel 122 farther from the first end 101. A waterproof cap 200 is also installed at the second end 102 of the head 110. The waterproof cap 200 can open or close the port of the instrument access channel 112 located at the second end 102. The waterproof cap 200 can be made of a rubber piece, and the waterproof cap 200 is movably connected to the head 110 so that the waterproof cap 200 can open or close the instrument access channel 112.

[0051] Optionally, the first flow channel 121, the second flow channel 122, the cable channel 123, and the installation chamber 124 are all disposed within the grip portion 120. The first flow channel 121, the cable channel 123, and the second flow channel 122 are arranged sequentially in the direction from the first end 101 to the second end 102. Furthermore, the ends of the first flow channel 121, the cable channel 123, and the second flow channel 122 away from the head 110 all extend to the end of the grip portion 120 away from the head 110, which may also be referred to as the tail end of the grip portion 120. The first flow channel 121 and the second flow channel 122 may both be through holes, and the cable channel 123 may be a groove. The first flow channel 121 and the cable channel 123 both communicate with the collecting channel 111, the second flow channel 122 communicates with the instrument inlet and outlet channel 112, and the installation chamber 124 communicates with the cable channel 123. Furthermore, a guide slope 125 is provided on the channel wall of the cable channel 123. One side of the guide slope 125 extends into the collecting channel 111. The guide slope 125 is arranged at an obtuse angle to the extension direction of the collecting channel 111. The guide slope 125 is configured to contact the front end of the cable body passing through the collecting channel 111 to deflect the front end of the cable body and allow it to enter the cable channel 123. The angle α between the guide slope 125 and the extension direction of the collecting channel 111 can be 130-140°. For example, the angle between the guide slope 125 and the extension direction of the collecting channel 111 can be 130°, 135°, or 140°.

[0052] It should be understood that by connecting the first flow channel 121 and the cable channel 123 to the collecting channel 111, the first flow channel 121 and the cable channel 123 share the collecting channel 111, thereby reducing the number of channels within the handle body 100, simplifying the processing steps, and reducing the processing and manufacturing costs. In addition, due to the design of the guide bevel 125, the front end of the cable body enters from one end of the collecting channel 111. When the cable body moves along the length of the collecting channel 111, the front end of the cable body contacts the guide bevel 125. The guide bevel 125 not only blocks the front end of the cable body, but also changes the direction of movement of the front end of the cable body, allowing the cable body to smoothly enter the cable channel 123 and then exit from the rear end of the cable channel 123, making the cable body easy and quick to install.

[0053] Please combine Figure 1 and Figure 2 Optionally, the tail end of the grip portion 120 is configured to be open, and a first connector 130 and a second connector 140 are integrally formed at the tail end of the grip portion 120. The first connector 130 is in communication with the first flow channel 121. The first connector 130 may be a pagoda connector for connecting to a liquid inlet pipe. The second connector 140 is in communication with the second flow channel 122. The second connector 140 may be a pagoda connector for connecting to a liquid discharge pipe. In order to prevent liquid from leaking from the tail end of the grip portion 120, a closure member 300 is installed at the tail end of the grip portion 120. The closure member 300 is detachably connected to the grip portion 120 to facilitate opening or closing the opening.

[0054] Optionally, the closure member 300 is provided with a first interface 310 and a second interface 320. The first interface 310 and the second interface 320 may be notches or through holes. The first interface 310 is for the first connector 130 to pass through, and the second interface 320 is for the second connector 140 to pass through. The cable channel 123 is connected to the second interface 320. In this way, after the closure member 300 closes the opening, the first connector 130 and the second connector 140 extend out of the closure member 300 and are exposed, facilitating connection with the liquid inlet and outlet pipes and facilitating the cable body to pass through the second interface 320.

[0055] Please combine Figure 1 and Figure 3 It should be understood that the closure member 300 may be a closure plate or a closure shell. When the closure member 300 is a closure plate, the closure member 300 may be connected to the grip portion 120 by bonding or screws. When the closure member 300 is a closure shell, the closure member 300 may be connected to the grip portion 120 by snap fastening or other means.

[0056] In addition, after the cable body is arranged in the cable channel 123, the cable body can be fixedly connected with the holding part 120 by means of glue dispensing, and the sealing performance is high. Alternatively, a positioning groove 126 can be arranged on the outer side of the holding part 120, the cable body is clamped in the cable channel 123, part of the cable body protrudes out of the cable channel 123, and the cable body is tied on the holding part 120 by means of a wire harness, the wire harness is located in the positioning groove 126, the position of the wire harness is stable and reliable, and the fixing effect is good.

[0057] The endoscope handle provided in the embodiment has the functions of connecting the insertion tube 001, the liquid inlet pipeline and the liquid outlet pipeline, and the handle body 100 itself has the functions of connecting the insertion tube 001, the liquid inlet pipeline and the liquid outlet pipeline, part of the structural members is saved, the assembly process is simplified, and the assembly efficiency is improved.

[0058] Please refer to Figure 4-Figure 5 The embodiment further provides an endoscope assembly which comprises the insertion tube 001, the image collector 002 and the endoscope handle. The insertion tube 001 is provided with the first lumen 011 and the second lumen 012, the insertion tube 001 is connected with the handle body 100, the first lumen 011 is in communication with the first flow channel 121, and the second lumen 012 is in communication with the second flow channel 122. The image collector 002 is installed at the front end of the insertion tube 001, and the image collector 002 is located in the first lumen 011.

[0059] Alternatively, the insertion tube 001 can be made by fixing an inner tube in an outer tube, part of the outer wall of the inner tube is in sealing contact with part of the inner wall of the outer tube, the first lumen 011 is defined between the inner tube and the outer tube, a plurality of liquid outlet holes 013 are arranged on the wall of the outer tube, and the image collector 002 does not affect the liquid outlet efficiency. The lumen of the inner tube is the second lumen 012, and part of the inner tube protrudes out of the outer tube. During assembly, the end of the inner tube protruding out of the outer tube is inserted into the instrument access channel 112 after passing through the collection channel 111 and is in contact with the second annular limiting surface 114, and the outer wall of the inner tube is in sealing contact with the channel wall of the instrument access channel 112. The outer tube is inserted into the collection channel 111, the outer wall of the outer tube is in sealing contact with the channel wall of the collection channel 111, and the end of the outer tube is in abutment with the first annular limiting surface 113. After the insertion tube 001 is assembled with the handle body 100, liquid is input from the liquid inlet pipeline, enters the collection channel 111 through the first flow channel 121, then enters the first lumen 011 defined by the inner tube and the outer tube, and finally enters the body through the liquid outlet holes 013. The liquid in the body enters the instrument access channel 112 from the second lumen 012, then enters the second flow channel 122, and is discharged from the liquid outlet pipeline.

[0060] Please refer to Figure 6In other embodiments, the handle body 100 and the insertion tube 001 can optionally be integrated into a single structure. This provides high structural strength, fewer joints, and fewer leak locations, making cross-contamination of incoming and outgoing fluids less likely. Specifically, the collection channel 111 and the first lumen 011 are integrated, and the second lumen 012 and the instrument access channel 112 are integrated, reducing the number of assembly steps required for the endoscope assembly.

[0061] The endoscope assembly provided in this embodiment saves assembly steps, simplifies assembly difficulty, and improves assembly efficiency by integrating multiple functional parts on the handle body 100.
