Description

Technical Field

[0001] This invention relates to endoscopes, and more particularly to an external battery box for an endoscope and an endoscope. Background Technology

[0002] Endoscopes are widely used diagnostic instruments in medicine and industry. Their shapes and structures vary depending on their application, but they all fundamentally consist of a lens, an insertion section, and a control handle. Some existing endoscopes use a power supply connected to an external power source within the control handle via wires to power components inside the handle and the lens; others use a battery integrated into the control handle for power. Using wires is limited by the location of the external power source and the length of the wire. A wire that is too long can easily become tangled, causing tripping hazards, while a wire that is too short makes it inconvenient to use in any location. Existing battery-powered endoscopes typically have the battery installed in the control handle in a fixed or detachable manner. With a fixed installation, the entire endoscope needs to be placed together to charge the battery. Since the endoscope's insertion part is usually a long, flexible tube, and the lens is a delicate component, charging requires a significant amount of space, and damage to the lens must be prevented during charging, making it extremely inconvenient to use. With a detachable installation, the limited space inside the control handle restricts the number of batteries that can be installed, thus limiting the power provided and consequently limiting the endoscope's usability for extended use. Summary of the Invention

[0003] To address the shortcomings of existing methods, this invention provides an external battery box for an endoscope and an endoscope itself.

[0004] The technical solution adopted by this invention to solve its technical problem is as follows: an external battery box for an endoscope, comprising a hollow shell with an open top, wherein an annular mounting member integrally formed with the shell and located inside the shell is connected to the top of the shell, the top of the mounting member is provided with an annular groove around the mounting member, the top of the outer groove wall of the annular groove is flush with the top of the shell, the top of the inner groove wall of the annular groove is higher than the top of the shell, and the top of the inner groove wall and the outer groove wall of the annular groove and the top of the shell form a step; a groove wall through hole is provided on the outer groove wall of the annular groove, the groove wall through hole is located on the groove wall of the annular groove corresponding to the inner wall of the shell near the bottom of the groove; a V-shaped limiting member is pivotally connected to the inner wall of the shell, the limiting member being positioned at the apex of the V-shaped structure and... The housings are pivotally connected, and the inner wall of the housing is provided with V-shaped torsion springs at both ends, which are connected to the housing and the limiting member respectively. One end of the limiting member can extend into the annular groove through a through hole in the groove wall, and the other end abuts against a button that is movably positioned on the housing. A rechargeable battery is installed inside the housing, located in the ring of the mounting member and spaced apart from the inner wall of the housing. The top of the mounting member is provided with a top cover that covers the ring of the mounting member. The mounting member extends a barrel-shaped mounting bracket inside the ring. The rechargeable battery is matched and installed in the mounting bracket. The top cover is located on the top of the mounting bracket. A circuit board is provided inside the housing, and a charging interface electrically connected to the circuit board is provided at the bottom of the housing. A battery box electrical connector electrically connected to the circuit board is provided on the inner wall of the annular groove.

[0005] Preferably, the housing has a housing through hole, the button is installed in the housing through hole, the bottom end of the button has a button protrusion extending circumferentially, and the edge of the housing through hole has a housing protrusion that can abut against the button protrusion.

[0006] Preferably, the bottom of the housing is also provided with an indicator light and an indicator light switch for controlling the indicator light, which are electrically connected to the circuit board.

[0007] Preferably, the inner wall of the housing extends with a connecting post, and the V-shaped torsion spring and the limiting member are both sleeved on the connecting post.

[0008] Preferably, the housing comprises a left shell and a right shell that engage with each other and have the same structure.

[0009] Preferably, a cover is provided at the connection between the left and right shells.

[0010] An endoscope includes an operating handle, an insertion part connected to the operating handle, and a lens connected to the front end of the insertion part. The operating handle is provided with an annular connecting part, which can be matched and inserted into the annular groove of the external battery box of the endoscope as described in any of the preceding claims.

[0011] Preferably, the outer wall of the connecting part is provided with a triangular groove for the matching limiting member to be inserted at the end away from the button, and the operating handle is also provided with an endoscope electrical connector.

[0012] The beneficial effects of this invention are as follows: This invention allows for the convenient installation of the endoscope's operating handle in the annular groove of the battery compartment, and its fixation within the annular groove by a limiting member. Batteries of different capacities can be installed inside the battery compartment, forming battery compartments that provide different levels of power. Different battery compartments can be installed to meet the varying needs of endoscope usage time, thus solving the problems of inconvenience associated with traditional methods of connecting external power sources via wires, and the inconvenience of charging batteries fixed inside the endoscope's operating handle. Furthermore, it solves the problem that when batteries are removably installed inside the operating handle, the internal space of the operating handle limits the ability to change battery capacity according to usage requirements.

Furthermore, the directional terms mentioned in the present invention, such as "up," "down," "front," "back," "left," "right," "inner," and "outer," are only for reference to the directions in the accompanying illustrations. The use of directional terms is for better and clearer explanation and understanding of the present invention, and is not intended to indicate or imply any necessary orientation of the present invention; therefore, they should not be construed as limitations on the present invention.

[0022] Examples of embodiments of the present invention Figures 1 to 6As shown, an external battery case for an endoscope includes a hollow housing 1 with an open top. The open top facilitates the installation of various components inside the housing 1. To prevent the battery case from slipping when being placed or removed, anti-slip textures can be provided on the housing 1 to increase the friction between the battery case and the hand. An annular mounting member 2, integrally formed with the housing 1 and located inside the housing 1, is connected to the top of the housing 1. The mounting member 2 is annular in structure and located inside the housing 1, connecting to the top of the housing 1. An annular groove 20 is provided on the top of the mounting member 2, encircling the mounting member 2. The side of groove 20 adjacent to the wall of housing 1 forms the outer groove wall of annular groove 20, and the side away from the wall of housing 1 forms the inner groove wall of annular groove 20. The top of the outer groove wall of annular groove 20 is flush with the top of housing 1, and the top of the inner groove wall of annular groove 20 is higher than the top of housing 1. That is to say, the outer groove wall of annular groove 20 is lower than the inner groove wall. The top of the inner groove wall of annular groove 20, its outer groove wall, and the top of housing 1 form a step. After the endoscope is installed on the battery box, the inner groove wall of annular groove 20 has a large contact area with the operating handle 9 of the endoscope, thereby ensuring the connection between the two. Structural stability; a groove wall through hole 21 is provided on the outer groove wall of the annular groove 20, which connects the annular groove 20 and the interior of the housing 1. The groove wall through hole 21 is located on the groove wall of the annular groove 20, which corresponds to the inner wall of the housing, near the bottom of the groove, that is, on the outer groove wall of the annular groove 20. In this way, after the battery box is installed on the endoscope, the groove wall through hole 21 can correspond to the edge of the connecting part 90 of the endoscope operating handle 9. When the limiting member 3 presses against the connecting part 90 of the operating handle 9, the force on the connecting part 90 of the operating handle 9 can better connect the two. For stability; a V-shaped limiting member 3 is pivotally connected to the inner wall of the housing 1. The limiting member 3 is set at the position corresponding to the through hole 21 of the groove wall on the inner wall of the housing 1, which makes it easy for the limiting member 3 to extend into the annular groove 20 through the through hole 21 of the groove wall. The limiting member 3 is pivotally connected to the housing 1 at the apex of the V-shaped structure. The limiting member 3 can rotate relative to the housing 1 when pivotally connected to the inner wall of the housing 1. The opening of its V-shaped structure faces the outer groove wall of the annular groove 20. A V-shaped torsion spring 4 is also provided on the inner wall of the housing 1, with both ends corresponding to the housing 1 and the limiting member 3. The V-shaped torsion spring 4 can make the limiting member 3 return to its initial state after rotating relative to the housing 1.One end of the limiting member 3 extends into the annular groove 20 through the through hole 21 in the groove wall, and the other end abuts against a button 5 that is movably mounted on the housing 1. The button 5 is mounted on the housing 1 and abuts against the limiting member 3. In the initial state, the end of the limiting member 3 corresponding to the through hole 21 extends into the annular groove 20 through the through hole 21. Pressing the button 5 applies force to the limiting member 3, causing it to rotate relative to the housing 1, and the end extending into the annular groove 20 will exit from the annular groove 20. Thus, when installing the battery box on the endoscope, first press the button 5 to make the end of the limiting member 3 corresponding to the annular groove 20 exit from the annular groove 20. After installation, release the pressure on the button 5. Under the action of the V-shaped torsion spring 4, the limiting member 3 extends into the annular groove 20 to press the endoscope in place, thus completing the installation and fixation of the battery box on the endoscope. The installation is convenient and simple. The rechargeable battery 6 is installed inside the housing 1 and is located in the ring of the mounting member 2. The rechargeable battery 6 is set in the ring of the mounting member 2, which limits the rechargeable battery 6 and creates a gap between the rechargeable battery 6 and the inner wall of the housing 1. When the battery box falls to the ground, it will buffer the force on the rechargeable battery 6 and protect the battery's safety. At this time, the rechargeable battery 6 can be set to batteries with different capacities according to needs, thus forming a battery box that can provide different amounts of power, so as to meet the needs of the endoscope's usage time. The design allows for the installation of different battery boxes to meet various needs, thus solving the inconvenience of using traditional external power supplies connected by wires, and the inconvenience of charging batteries fixed inside the endoscope operating handle. It also addresses the issue of limited internal space when batteries are removably installed inside the operating handle 9, preventing the replacement of batteries with different capacities as needed. For example, a single 18650 lithium battery can meet the short-term use of the endoscope, while two or more 18650 batteries connected in series can provide more power for extended use. The top of the mounting component 2 is equipped with a top cover 7 that covers the ring on the mounting component 2, thus avoiding... The rechargeable battery 6 falls off the mounting component 2, maintaining the stability of the rechargeable battery 6 mounting structure; a circuit board 8 is provided inside the housing 1, and a charging interface 12 electrically connected to the circuit board 8 is provided at the bottom of the housing 1. The battery box can be conveniently charged using the charging interface 12, and there is no need to connect the battery box and the endoscope together during charging, which is convenient to use; a battery box electrical connector 13 electrically connected to the circuit board 8 is provided on the inner wall of the annular groove 20. After the battery box is installed on the endoscope, the battery box electrical connector 13 is electrically connected to the endoscope electrical connector 92 on the endoscope. If the battery box electrical connector 13 and the endoscope electrical connector 92 are mating surface mount connectors.

[0023] Regarding the installation of button 5 on housing 1, housing 1 is provided with housing through hole 14. Button 5 is installed in housing through hole 14. Button protrusion 50 extends circumferentially from the bottom end of button 5. Housing protrusion 140 extends from the edge of housing through hole 14 and can abut against button protrusion 50. During installation, button 5 is inserted into housing through hole 14 from the inner end and passes through housing through hole 14. When button 5 is pulled outward, the top surface of button protrusion 50 presses against the bottom surface of housing protrusion 140. That is, the outer end surface of button protrusion 50 abuts against the inner end surface of housing protrusion 140, thereby limiting the outward movement of button 5 on housing 1 and preventing it from being pulled out of housing 1. The bottom end of button 5 abuts against limiting member 3, which prevents button 5 from falling into housing 1.

[0024] Regarding the structure of the mounting component 2, the mounting component 2 has a barrel-shaped mounting bracket 22 extending inside the ring. The rechargeable battery 6 is matched and installed inside the mounting bracket 22. The top cover 7 is placed on the top of the mounting bracket 22. That is, the mounting bracket 22 is set on the inner side wall of the annular structure of the mounting component 2, that is, on the side of the inner groove wall of the annular groove 20 away from the housing 1. The top cover 7 closes the opening of the mounting bracket 22, thus ensuring the stability of the rechargeable battery 6 mounting structure.

[0025] For the pivotal structure of the limiting member 3 on the inner wall of the housing 1, the inner wall of the housing 1 extends with a connecting post 16. The V-shaped torsion spring 4 and the limiting member 3 are both sleeved on the connecting post 16. The limiting member 3 can be conveniently set inside the housing 1 by using the connecting post 16.

[0026] Further improvements, such as Figure 1 and Figure 4 As shown, the bottom of the housing 1 is also provided with an indicator light 15 electrically connected to the circuit board 8 and an indicator light switch 150 for controlling the indicator light 15. The indicator light 15 indicates the power level of the rechargeable battery 6. When it is necessary to know whether the rechargeable battery 6 is fully charged, the indicator light switch 150 can be used to turn on the indicator light 15 to display the power level of the rechargeable battery 6. When it is not necessary to display, the indicator light switch 150 can be turned off.

[0027] Further improvements, such as Figure 4As shown, the housing 1 includes a left shell 10 and a right shell 11 with the same structure that engage with each other. Dividing the housing 1 into two parts with the same structure facilitates the production of the housing 1 and the installation of the various components inside the housing 1. Correspondingly, the mounting parts 2 and the annular grooves 20 on the mounting parts 2 are provided in the housing 1 with open ends. After the left shell 10 and the right shell 11 engage, the end-opening mounting parts 2 and the annular grooves 20 on the mounting parts 2 form a ring. For example, the original annular mounting parts and annular grooves can be set into a semi-annular structure. In order to cover the joint between the left and right shells, a cover 17 is provided at the connection between the left shell 10 and the right shell 11. In addition to the connection structure of the left and right shells themselves, the cover 17 applies a force to cover the joint and tighten the left and right shells at the same time, maintaining the stability of the connection structure between the left and right shells.

[0028] An endoscope, such as Figure 6 and Figure 7As shown, this endoscope, like a traditional endoscope, includes an operating handle 9, an insertion part connected to the operating handle 9, and a lens connected to the front end of the insertion part. The operating handle 9 has an annular connecting part 90, which can be inserted into the annular groove 20 of the external battery compartment of the endoscope described above. The connecting part 90 and the operating handle 9 are integrally formed. After the battery compartment is installed on the operating handle 9, the connecting part 90 is engaged in the annular groove 20. The interior of the annular structure of the connecting part 90 avoids the inner wall of the annular groove 20, and the outer wall of the connecting part 90 is in contact with the annular groove 20. Corresponding to the outer wall of the groove 20, the end of the limiting member 3 corresponding to the through hole 21 in the groove wall passes through the through hole 21 and presses against the outer wall of the connecting part 90, applying pressure to the connecting part 90 to maintain the stability of the connection structure between the battery box and the operating handle 9. The outer wall of the connecting part 90 is provided with a triangular groove 91 that matches the end of the limiting member 3 away from the button 5 and is inserted into it. That is, the groove has a triangular cross-section, which facilitates the insertion of the limiting member 3 to limit the operating handle 9. An endoscope electrical connector 92 is also provided inside the operating handle 9, which is electrically connected to the battery box. The head 13 is connected to establish an electrical connection between the battery box and the operating handle 9, providing power to the endoscope. At this time, the positions of the triangular slot 91 on the operating handle 9, the endoscope electrical connector 92, and the slot wall through hole 21 and battery box electrical connector 13 on the battery box are correspondingly set. For example, the triangular slot 91 and endoscope electrical connector 92 are first set on the operating handle 9, and then the slot wall through hole 21 and battery box electrical connector 13 are set on the battery box according to the positions of the triangular slot 91 and endoscope electrical connector 92 on the operating handle 9. Alternatively, the slot wall through hole 21 and battery box electrical connector 13 can be set on the battery box first. The wall through hole 21 and the battery box electrical connector 13 are installed. Then, the triangular slot 91 and the endoscope electrical connector 92 are set on the operating handle 9 according to the setting positions of the wall through hole 21 and the battery box electrical connector 13. As long as the limiting member 3 can be locked in the triangular slot 91 through the wall through hole 21 after the battery box is installed on the operating handle 9, the battery box electrical connector 13 and the endoscope electrical connector 92 are connected and electrically conductive. At this time, their respective indicator marks can be set at the corresponding positions. When installing the battery box onto the operating handle 9, the corresponding indicator marks can be aligned.

[0029] Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
