[0032] Although the present invention can be easily embodied in different forms of embodiments, only some of the specific embodiments are shown in the drawings and will be described in detail in this specification. It should be understood that this description should be regarded as an exemplary illustration of the principles of the invention and is not intended to limit the invention to that described herein.

[0033] Thus, a feature indicated in this specification will be used to illustrate one of the features of an embodiment of the present invention, rather than implying that each embodiment of the present invention must have the described feature. In addition, it should be noted that this specification describes many features. Although some features can be combined together to illustrate possible system designs, these features can also be used in other combinations that are not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

[0034] In the embodiments shown in the drawings, the indications of directions (such as up, down, left, right, front and back) used to explain the structure and movement of various elements of the present invention are not absolute but relative. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the description of the positions of these elements changes, the indications of these directions also change accordingly.

[0035] The preferred embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings of this specification.

[0036] The present invention provides a disposable endoscope. Compared with a traditional endoscope, the disposable endoscope is reusable. After the first use, the traditional endoscope needs to be centrally disinfected in preparation for the next use. Since the endoscope is small in size and has many corners and slits, it is often impossible to achieve complete disinfection of the endoscope. Therefore, there is a risk of cross infection when using a traditional endoscope repeatedly. The disposable endoscope of this embodiment discards the contaminated part to avoid repeated use.

[0037] See also Figure 1 and Figure 2 The disposable endoscope of this embodiment includes a handle 10 and an insertion part 20 of the disposable endoscope. Since the insertion part is contaminated during use, the part with the insertion part is discarded after use of the disposable endoscope, which can improve the hygiene of the endoscope and ensure that the patient can use it safely. In addition, after removing the discarded part, the remaining part is not contaminated and can be reused, saving costs.

[0038] The insertion portion 20 is used to enter the cavity of the human body. The insertion portion 20 can gradually enter the affected area as the cavity of the human body bends. Figure 2 The insertion part 20 of the disposable endoscope includes an insertion tube 21, a curved part, a traction wire 23 and a head end 24. The insertion tube 21 is sleeved on the outside of the curved part, and the head end 24 is located at the front end of the curved part. The traction wire 23 is connected to the curved part, and the movement of the traction wire 23 can operate the bending direction of the curved part, control its forward movement and bending, etc.

[0039] See also Figure 2 The handle 10 of the disposable endoscope includes a first structure 11 and a second structure 12 that are mutually driven and connected. The first structure 11 includes a driving part 13. The driving part 13 is used to drive and adjust the bending angle of the insertion part 20, and the second structure 12 is used to connect with the insertion part 20.

[0040] See also Figure 3 The first structure 11 is provided with a first joint 111, and the second structure 12 is provided with a second joint 121. The first joint 111 and the second joint 121 are detachably connected. When the disposable endoscope is ready to be used, the first joint 111 and the second joint 121 are connected to each other to assemble the handle 10 of the disposable endoscope. After the disposable endoscope is used, the first joint 111 and the second joint 121 are disassembled to separate the first structure 11 from the second structure 12.

[0041] See also Figure 2 Therefore, after the use of the disposable endoscope handle 10 of this embodiment, since the second structure 12 connected to the insertion part 20 is detachable from the first structure 11, the second structure 12 is discarded along with the insertion part 20, and the first structure 11 that is not contaminated is retained. Therefore, the first structure 11 is not contaminated and can be reused, reducing the use cost. In addition, each use of the second structure 12 and the insertion part 20 is the first use, which can ensure the sanitary standard of the disposable endoscope and improve the safety of using the endoscope.

[0042] See also Figure 3 Specifically in this embodiment, the driving unit 13 includes a first gear 131 and a first rack 132. The first gear 131 is meshed with one end of the first rack 132, and the first gear 131 is rotated to drive the first rack 132 to extend and retract.

[0043] Furthermore, there are two first racks 132 and two first gears 131. The two first racks 132 are arranged in parallel. The driving part 13 also includes a rotating wheel 133. The plurality of rotating wheels 133 are arranged coaxially up and down. The rotating wheel 133 is connected to the bending part 22 through the traction wire 23. The rotating wheel 133 rotates to drive the traction wire 23 to move, so that the bending direction of the bending part 22 can be operated.

[0044] Specifically in this embodiment, the rotating wheel 133 includes a first rotating wheel 134 and a second rotating wheel 135. The first rotating wheel 134 and the second rotating wheel 135 drive two first gears 131 respectively. The first gear 131 rotates forward and reversely on the first rack 132, thereby driving the first rack 132 to telescope. Among them, one of the two first gears 131 is used to adjust the bending angle of the insertion portion 20 in the left-right direction, and the other first gear 131 is used to adjust the bending angle of the insertion portion 20 in the up-down direction.

[0045] It can be understood that rotating the first rotating wheel 134 can adjust the bending angle of the insertion portion 20 in the left-right direction. Rotating the second rotating wheel 135 can adjust the bending angle of the insertion portion 20 in the up-down direction. Therefore, rotating the first rotating wheel 134 and the second rotating wheel 135 can respectively adjust the corresponding first gear 131 to rotate and drive the corresponding first rack 132 to extend and retract. The control direction of the first rotating wheel 134 and the second rotating wheel 135 is not limited here, as long as the first rotating wheel 134 and the second rotating wheel 135 cooperate with each other to achieve control of the bending angle.

[0046] See also Figure 3 , specifically in this embodiment. The first connector 111 is provided at one end of the first rack 132 away from the first gear 131. If there are two first racks 132, there are also two first connectors 111.

[0047] Please also see Figure 4 The second gear 122 of the second structure 12 is meshed with the second rack 123, and the second rack 123 is drivingly connected to the first rack 132. The first rack 132 is extended and retracted to drive the second rack 123 to extend and retract, thereby driving the second gear 122 to rotate. Therefore, when the rotating wheel 133 is rotated, the transmission value of the adjustment operation is pulled on the steel wire 23 through the transmission connection between the first rack 132 and the second rack 123, thereby achieving the purpose of adjusting the bending angle of the insertion portion 20.

[0048] Specifically in this embodiment, the second structure 12 includes a plurality of second gears 122 and a plurality of second racks 123. Specifically, there are two first racks 132, and four second racks 123, and the four second racks 123 are distributed in a rectangular shape. Since the insertion portion 20 has four bending directions. The insertion portion 20 includes four traction wires 23. The traction wires 23 are used to drive the head end 24 of the traction portion to adjust the bending along four directions. Each traction wire 23 is respectively connected to a second rack 123. The movement of the second rack 123 drives the traction wire 23 to move.

[0049] In other embodiments, the number of the first rack 132 and the second rack 123 may be other numbers. Correspondingly, the adjustment direction of the insertion portion 20 may also be other angles, which are not limited here.

[0050] For the convenience of explanation, two second racks 123 and a second gear 122 are now divided into one group. The four second gears 122 are divided into two groups. The teeth of the second racks 123 in the same group are arranged opposite to each other, and the opposite sides of a second gear 122 are divided into two sides that mesh with the second gear 122. Each group of second racks 123 corresponds to a first gear 131 and a first rack 132, so that the first gear 131 can adjust the bending direction of the insertion portion 20.

[0051] The second rack 123 in the same group includes a second active rack 1231 and a second driven rack 1232. The second active rack 1231 and the second driven rack 1232 in the same group are meshed and connected with the same second gear 122. The second joint 121 is provided at one end of the second active rack 1231, and the second active rack 1231 is drivingly connected to the first rack 132 through the first joint 111 and the second joint 121. The second active rack 1231 is pushed and retracted by the first rack 132, so that the second gear 122 rotates and drives the second driven rack 1232 to retract.

[0052] For two second racks 123 in the same group, only one of the first racks 132 needs to be relatively docked with one second active rack 1231 and detachably connected to realize the driving of the two second racks 123. Therefore, by driving the second driven rack 1232 through the second gear 122, the number of first racks 132 can be reduced, and the difficulty of docking between the first rack 132 and the second rack 123 can be reduced, which is conducive to realizing the overall detachable setting of the first structure 11 and the second structure 12.

[0053] Furthermore, the second connector 121 is located at one end of the second active rack 1231 close to the first rack 132. The second connector 121 is engaged with the first connector 111.

[0054] See also Figure 5 and Figure 6 Specifically, the first joint 111 includes an arc-shaped protrusion 1111 and a rotating shaft 1112. The arc-shaped protrusion 1111 is provided with an arc-shaped outer surface. The rotating shaft 1112 is provided at one end of the arc-shaped protrusion 1111. The second joint 121 is provided with a slot 124 for accommodating the arc-shaped protrusion 1111, and the slot 124 is engaged and connected with the arc-shaped protrusion 1111 of the first joint 111. An axial hole for accommodating the rotating shaft 1112 is provided at the end of the second joint 121. In addition, the arc-shaped protrusion 1111 can be rotatably accommodated in the slot 124, and the rotating shaft 1112 can be rotatably accommodated in the axial hole.

[0055] Furthermore, the second joint 121 is provided with a guide portion 125 at one side of the slot 124, and the guide portion 125 extends from one side of the second joint 121 into the slot 124. After the second joint 121 is aligned with the first joint 111, by rotating the first structure 11 or the second structure 12, the first joint 111 and the second joint 121 rotate relative to each other, so that the arc-shaped outer surface of the arc-shaped protrusion 1111 smoothly slides into the slot 124 along the guide portion 125, and is engaged with the slot 124. Specifically, the guide portion 125 is a smooth arc-shaped surface.

[0056] Furthermore, the first structure 11 or the second structure 12 is reversed, and the first joint 111 and the second joint 121 are relatively rotated, so that the arc-shaped protrusion 1111 is disengaged from the slot 124, and the rotating shaft 1112 is disengaged from the shaft hole, thereby realizing the separation of the first joint 111 and the second joint 121, and the first structure 11 and the second structure 12 are separable.

[0057] See also Figure 7 and Figure 8 Specifically, in this embodiment, the first structure 11 further includes an alignment joint 112. The alignment joint 112 is located at the center of the plurality of first joints 111. An alignment structural member 126 is provided on the second structure 12. The alignment structural member 126 is also located at the center of the plurality of second joints 121. After the alignment structural member 126 and the alignment joint 112 are aligned and connected with each other, it means that the first structure 11 and the second structure 12 are aligned with each other to assist the first joint 111 and the second joint 121 to dock with each other.

[0058] Specifically in this embodiment, the alignment joint 112 is a convex column, and the alignment structure 126 is a groove for accommodating the convex column. The alignment structure 126 is located at the center of the four second gears 122 distributed in a rectangular shape, and the alignment joint 112 is also correspondingly located at the middle of the two first joints 111, and is plugged in with the alignment structure 126.

[0059] Please also see Figure 5 and Figure 6 , and the arc-shaped protrusion 1111 of the first joint 111 rotates at the opening of the slot 124 of the second joint 121, that is, the arc-shaped protrusion 1111 is inserted into the slot 124 to realize the connection between the first joint 111 and the second joint 121. The openings of the slots 124 of the two second joints 121 are arranged alternately. When the arc-shaped protrusion 1111 is placed at the opening of the slot 124, it is avoided that the alignment joint 112 interferes with the setting of the arc-shaped protrusion 1111, which affects the connection between the first joint 111 and the second joint 121.

[0060] In other embodiments, the first connector 111 and the second connector 121 may be connected to each other in a docking and detachable manner by means of magnetic attraction, screw connection, or the like.

[0061] See also Fig. 9 , since the head end 24 of the insertion part 20 is provided with an image acquisition module 25. The image acquisition module 25 acquires the image signal inside the human body cavity. The above-mentioned disposable endoscope needs to send the above-mentioned image signal to the host, and the host can complete the final processing of the image signal.

[0062] Specifically in this embodiment, the first structure 11 further includes a first circuit 117. The second structure 12 further includes a second circuit 127. The second circuit 127 is electrically connected to the image acquisition module 25 for transmitting image signals.

[0063] The first circuit 117 is provided with a first port 1171, and the second circuit 127 is provided with a second port 1271. The first connector 111 is butt-connected with the second connector 121, and the first port 1171 is electrically connected with the second port 1271. The image signal is sent to the first circuit 117 via the second circuit 127.

[0064] The first circuit 117 includes a digital signal processing circuit 1172. The image signal is transmitted to the digital signal processing circuit 1172 through the first port 1171 and the second port 1271. The digital signal processing circuit 1172 can compress the image signal, amplify the signal strength, etc. It can be understood that the digital signal processing circuit 1172 can be an image processing chip or a position positioning chip.

[0065] Usually, a disposable endoscope needs to be electrically connected to a host through a long wire 30 to transmit the image signal to the host. However, since the image signal is not convenient for long-distance transmission, if the image signal is directly transmitted to the host, the image signal may generate large noise, affecting the accuracy of the image signal. Therefore, the disposable endoscope of this embodiment needs to be amplified by the image processing circuit before transmission. The image processing circuit is arranged in the handle 10, which can solve the problem of signal transmission distance and facilitate the image signal amplified by the image processing circuit to be accurately transmitted to the host and perform signal processing.

[0066] One end of the first circuit 117 away from the second circuit 127 is used to connect to the host, so that the image acquisition module 25 can be electrically connected to the host through the first circuit 117 and the second circuit 127. Then the image signal can be processed by the digital signal processing circuit 1172 and then transmitted to the host, and the host can complete the final processing of the image signal. The handle 10 of the disposable endoscope can realize the detachable connection between the first structure 11 and the second structure 12, and can also realize the electrical connection between the first circuit 117 and the second circuit 127 through the first port 1171 and the second port 1271, so as to ensure that the image signal can be transmitted to the host for signal processing.

[0067] Furthermore, when the first structure 11 and the second structure 12 are disassembled from each other, the first structure 11 is disassembled from the handle 10. During the use of the above-mentioned disposable endoscope, only the second structure 12 of the handle 10 is contaminated, so only the second structure 12 of the handle 10 needs to be discarded, and the first structure 11 can be retained for reuse, thereby avoiding the first structure 11 from being discarded together with the insertion portion 20, causing waste of resources and saving use costs. Furthermore, the first circuit 117 is also retained with the first structure 11, and the digital signal processing circuit 1172 can also be retained, further avoiding waste of resources and further saving the use cost of the above-mentioned disposable endoscope.

[0068] Specifically in this embodiment, the first structure 11 further includes a first housing 118, and the second structure 12 further includes a second housing 128. The first housing 118 is provided with a first receiving cavity. The first receiving cavity is used to receive components such as the first connector 111 and the first circuit 117. The second housing 128 is provided with a second receiving cavity. The second receiving cavity is used to receive components such as the second connector 121 and the second circuit 127.

[0069] The first shell 118 and the second shell 128 are detachably connected. The first shell 118 and the second shell 128 are spliced ​​together to form the handle 10 of the disposable endoscope, providing a general appearance structure for providing a bearing function. The first shell 118 and the second shell 128 are injection molded structures.

[0070] Specifically in this embodiment, the first housing 118 and the second housing 128 are connected by a snap fit. The first housing 118 and the second housing 128 are provided with a snap hook 119 or a snap buckle, etc., which cooperate with each other to achieve the snap fit.

[0071] Therefore, in the disposable endoscope in the above embodiment, when the endoscope is used, the first structure 11 of the handle 10 will not enter the human body and will not be contaminated. Therefore, the first structure 11 of the handle 10 can be reused without the risk of infection between patients due to the reuse of the first structure 11. Therefore, the disposable endoscope can minimize the number of discarded components and save costs while ensuring safe use.

[0072] Furthermore, the first joint 111 of the first structure 11 and the second joint 121 of the second structure 12 cooperate with each other to achieve a detachable connection. When the first joint 111 and the second joint 121 are docked with each other, the structural design of the alignment joint 112 and the guide portion 125 greatly reduces the difficulty of aligning the first joint 111 and the second joint 121, and docking and locking can be achieved by rotating, which is easy to operate.

[0073] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present invention can be embodied in a variety of forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
