Description

Connecting assembly for endoscope device and endoscope system

Technical Field

The present disclosure relates to an endoscope, and more particularly, to a connecting assembly for an endoscope apparatus and an endoscope system.

Background

Conventionally, endoscope apparatuses have been widely used in the fields of medical treatment, industry, and the like. For example, human intervention diagnosis may be performed using an endoscopic device, or a machine (e.g., an engine) may be checked for a fault using an endoscopic device. Taking an endoscope device applied to the medical field as an example, in the diagnosis and treatment process, after a camera module of the endoscope device is placed in a human body cavity, a doctor can observe the inside of the human body cavity through a display device in communication connection with the endoscope device, and more accurate patient information can be acquired.

The endoscope apparatus may be generally divided into a control section (e.g., including a power supply, a main control circuit board, etc.) and an image pickup section (e.g., including an operation handle, an insertion section, a camera module, etc.). Most endoscope devices are designed to be non-detachably connected or integrated between a control part and an image acquisition part, the structure is complex, and the replacement cost is high after the endoscope device is damaged. When the control part and the image acquisition part are detachably connected, the problems of reliability in connection, convenience in disassembly and assembly and the like need to be considered.

Accordingly, it is desirable to provide a connection assembly that can be used to reliably connect the control section and the image capturing section of an endoscopic device and that is easy to assemble and disassemble.

Detailed Description

In order to more clearly illustrate the technical solutions of the embodiments of the present disclosure, the drawings used in the description of the embodiments will be briefly described below. It is obvious that the drawings in the following description are only examples or embodiments of the present description, and that for a person skilled in the art, the present description can also be applied to other similar scenarios on the basis of these drawings without inventive effort. Unless otherwise apparent from the context, or otherwise indicated, like reference numbers in the figures refer to the same structure or operation.

It should be understood that "system", "apparatus", "unit" and/or "module" as used herein is a method for distinguishing different components, elements, parts, portions or assemblies at different levels. However, other words may be substituted by other expressions if they accomplish the same purpose.

As used in this specification and the appended claims, the terms "a," "an," "the," and/or "the" are not intended to be inclusive in the singular, but rather are intended to be inclusive in the plural, unless the context clearly dictates otherwise. In general, the terms "comprises" and "comprising" merely indicate that steps and elements are included which are explicitly identified, that the steps and elements do not form an exclusive list, and that a method or apparatus may include other steps or elements.

Flow charts are used in this description to illustrate operations performed by a system according to embodiments of the present description. It should be understood that the preceding or following operations are not necessarily performed in the exact order in which they are performed. Rather, the various steps may be processed in reverse order or simultaneously. Meanwhile, other operations may be added to the processes, or a certain step or several steps of operations may be removed from the processes.

In use of an endoscopic device, a display device (e.g., a computer or other display device) is often required to be in communicative connection with the endoscopic device to display images captured by the endoscopic device, thereby providing more accurate information to a user of the endoscopic device. For example, more accurate patient information (e.g., lesion position, lesion degree, etc.) may be provided to a doctor through a medical endoscope, or more accurate information about the internal space of a machine (e.g., machine failure information (e.g., crack position, shape, etc. on an engine fuel pipe) may be provided to a machine inspector through an industrial endoscope.

In some embodiments, the structure of the endoscopic device may be divided into a first portion and a second portion. Wherein the first part may be used for image acquisition. Specifically, the first portion may include at least an operating handle, an insertion portion, and a camera module disposed at a front end of the insertion portion, and the camera module may collect images in a patient cavity (e.g., a chest cavity, an abdominal cavity, etc.) or a machine cavity (e.g., a fuel pipe of an engine) by inserting the insertion portion into the patient cavity or the machine cavity to generate corresponding image signals.

While the second portion may be used to control the first portion (e.g., camera module) for image acquisition and/or to supply power to the first portion (e.g., camera module). Specifically, the second portion may include at least a main control circuit board and/or a power supply, where the main control circuit board may be used to control the first portion to perform image acquisition, and the power supply may supply power to the first portion.

In addition to this, the second section can also be used to establish a communication connection between the endoscopic device and the display device, for example, to transmit the image signals captured by the first section to the display device for image display. In some embodiments, the communication connection between the endoscopic device and the display device may be a wired connection. For example, a data transmission interface (e.g., a USB interface) may be provided on the second portion and the display device, and the endoscope device and the display device may be connected by wire via the data transmission interface. In some embodiments, the communication connection between the endoscopic device and the display device may be a wireless connection. For example, a wireless transmitting module (e.g., a bluetooth transmitting module) may be disposed on the second portion, a wireless receiving module (e.g., a bluetooth receiving module) paired with the wireless transmitting module may be disposed on the display device, and the endoscope device and the display device may be wirelessly connected through a pairing connection between the wireless transmitting module and the wireless receiving module.

In some embodiments, the first and second portions of the endoscopic device may be non-detachably connected or integrally designed, for example, the second portion may be integrated into an operating handle, and an image display module (e.g., a display screen) may be provided on the operating handle instead of the display device. This not only increases the size of the endoscope apparatus, but also complicates the structure and the internal circuit design, and the replacement cost is also high when the first part or the second part is damaged.

In some embodiments, the first and second portions of the endoscopic device may be removably coupled. When the first portion and the second portion of the endoscope apparatus are detachably connected, it is necessary to consider whether the detachable connection between the first portion and the second portion is reliable, whether the attaching and detaching operation is simple and quick, and the like.

The present description embodiments provide a connection assembly for an endoscopic device, the connection assembly including a locking portion provided on a first portion of the endoscopic device, a locking fitting provided on a second portion, and an unlocking operation member fixedly connected with the locking fitting. The connecting assembly in the embodiments of the present description drives the locking mating part to move between the first position and the second position by unlocking the operating part, so that the locking mating part and the locking part are mated and separated from each other, and further, the detachable connection between the first part and the second part of the endoscope apparatus is realized. The locking matching part and the locking part are matched and connected with each other to realize reliable connection between the first part and the second part, and the locking matching part is driven to move by operating the unlocking operation piece (for example, pressing the unlocking operation piece), so that the difficulty of assembly (or connection) and/or disassembly between the first part and the second part can be reduced, for example, the assembly and/or disassembly between the first part and the second part can be quickly and effectively realized only by pressing the unlocking operation piece.

The coupling assembly in the embodiments of the present disclosure may be applied to an endoscope apparatus in the medical and industrial fields, but is not limited to the endoscope apparatus, and any related apparatus, device, structure, and the like having the coupling assembly in the embodiments of the present disclosure should be within the scope of protection of the present disclosure.

The connecting assembly for an endoscope apparatus provided in the embodiments of the present specification will be described in detail below with reference to the accompanying drawings.

Fig. 1 is a general assembly view of an endoscopic device with a connection assembly shown in accordance with some embodiments of the present description. Fig. 2 is a partial exploded view of an endoscopic device with a connection assembly shown in accordance with some embodiments of the present description. FIG. 3 is a sectional view of the area A of the endoscope apparatus shown in FIG. 1 taken along the direction of section B-B.

Referring to fig. 1 and 2, the endoscopic device 100 may include a first portion 110 and a second portion 120, the first portion 110 and the second portion 120 being connected by a connecting assembly 130. Further, as shown in fig. 2, the connecting assembly 130 may include a locking part 131 provided on the first part 110, a locking fitting part 132 provided on the second part, and an unlocking operation member 133 fixedly connected with the locking fitting part 132. The unlocking operation member 133 can move the locking coupling portion 132 between a first position and a second position, and when the locking coupling portion 132 is located at the first position, the locking coupling portion 132 can be coupled with the locking portion 131, so that the first portion 110 and the second portion 120 are connected to each other; and when the locking fitting 132 is moved from the first position to the second position, the locking fitting 132 can be separated from the locking part 131, thereby separating the first and

second parts

110 and 120 from each other. In some embodiments, as shown in fig. 3, the unlocking operation member 133 can move the locking mating part 132 left and right. Wherein the first position may be a maximum displacement of the locking fitting 132 moving to the right, and the second position may be a maximum displacement of the locking fitting 132 moving to the left.

In some embodiments, the first portion 110 may be used to acquire image signals. Specifically, the first portion includes an operating handle 111, an insertion portion 112, and an image pickup module 113 disposed at a front end of the insertion portion 112 (or referred to as a distal end of the insertion portion 112). During the use of the endoscope apparatus 100, the insertion portion 112 is inserted into a body cavity (e.g., a chest cavity, an abdominal cavity, etc.) or a machine cavity (e.g., an engine fuel pipeline), so that the camera module 113 can capture images of the corresponding body cavity or cavity to acquire image signals. The bending angle or bending direction of the insertion portion 112 can be adjusted by operating the operating handle (for example, toggling the toggle lever 115 on the operating handle 111), and then the position, viewing angle, etc. of the camera module 113 in the corresponding body cavity or cavity can be adjusted, so that the camera module 113 can shoot multi-angle and more comprehensive images in the corresponding body cavity or cavity, thereby helping doctors or related operators to obtain more accurate patient information or fault information. In some embodiments, the operating handle 111 is provided with a boss 114, and the locking portion 131 may be provided on a side wall of the boss 114.

In some embodiments, the insertion portion 112 is a tubular structure having a tubular space for accommodating an optical cable and/or an electrical cable (or referred to as a light guide bundle and/or an image guide bundle) for connecting the camera module 113 and the operation handle 111. In some embodiments, the front end of the insertion portion 112 may be a bending portion (not shown in the drawings), and the manipulation handle 111 may adjust a bending angle and a bending direction of the bending portion, so as to adjust a position, a viewing angle, and the like of the camera module 113 in a corresponding body cavity or cavity. In some embodiments, the bend has a mesh structure or a serpentine structure. In some embodiments, the camera module 113 may include an image sensor, wherein the image sensor may be one or more of a CCD sensor, a CMOS sensor, and a DPS sensor.

In some embodiments, the second portion 120 may be used to control the first portion 110 to acquire image signals. Referring to fig. 1 and 2, the second portion 120 may include a main control circuit board (PCB)121, and the main control circuit board 121 is provided with a key 122.

In some embodiments, pressing key 122, main control circuit board 121 may generate a control signal, the control signal may be transmitted to first portion 110, and first portion 110 may start capturing image signals or stop capturing image signals based on the control signal. A description of how the control signal is passed to the first portion 110 may be found elsewhere in this specification and will not be described in detail here.

In some embodiments, the second portion 120 may also be used to supply power to the first portion 110, for example, to power the camera module 113 in the first portion 110. With continued reference to fig. 2, the second portion 120 can include a power supply 123, and the power supply 123 can be used to supply power to the first portion 110. In some embodiments, the power source 123 may be a battery, and the battery may include a lithium ion battery, a nickel metal hydride battery, a nickel cadmium battery, a lead acid battery, or the like. In some embodiments, when the power source 123 is a storage battery, the main control circuit board 121 is further provided with a power management module 124 electrically connected to the power source 123, which can be used to prevent overcharge and overdischarge of the power source 123, prolong the service life of the power source 123, monitor the state of the power source 123, and the like. In some embodiments, power source 123 may also be a dry cell battery. In some embodiments, when the endoscopic device 100 requires charging, the second portion 120 may be detached from the endoscopic device 100 (even if the second portion 120 is separated from the first portion 110), and then the second portion 120 may be separately charged.

In some embodiments, the power supply 123 may be controlled to supply power to the first portion 110 and/or stop supplying power by pressing the key 122, so as to control the first portion 110 to perform image capturing.

In some embodiments, the second portion 120 can also be used to enable the endoscopic device to establish a communication connection with a display device to transmit image signals captured by the endoscopic device to the display device for display. In some embodiments, a data transmission interface (e.g., a USB interface) (not shown in the figure) may be provided on the main control circuit board 121, and the wired connection between the endoscope apparatus 100 and the display apparatus is realized through the data transmission interface. In some embodiments, a wireless transmission module (e.g., a bluetooth module) may also be disposed on the master circuit board 121. The wireless communication connection of the second portion 120 (i.e., the endoscopic device 100) to the display device is achieved via a bluetooth module. In some embodiments, the second portion 120 and the display device may be connected in wired or wireless communication over a network.

In some embodiments, in order to ensure that the mutual coupling between the locking portion 131 and the locking mating portion 132 can achieve a reliable connection between the first part 110 and the second part 120, referring to fig. 2, the locking mating portion may include an annular latch 1321, and the locking portion 131 may include a latch slot 1311 matched with the annular latch 1321, i.e., the annular latch 1321 can enter the latch slot 1311 to be latched with the latch slot 1311. In some embodiments, the annular latch 1321 may be a part or all of the locking fitting 132, and the card slot 1311 may be a part or all of the locking part 131. Therefore, in some cases, the locking portion 131 and the card slot 1311, and the locking mating portion 132 and the annular cartridge 1321 may be used interchangeably in this specification.

When the locking mating portion 132 is driven by the unlocking operation member 133 to move to the first position, the annular latch 1321 may be latched with the latch slot 1311, so that the locking portion 131 and the locking mating portion 132 are coupled to each other, and the first portion 110 and the second portion 120 are coupled to each other. Through the clamping design of the annular clamping block 1321 and the clamping groove 1311, the relative movement between the first part 110 and the second part 120 can be effectively limited, and the purpose of reliable connection is achieved. In some embodiments, the annular clip 1321 may be replaced with a regular or irregular shaped clip such as a triangular clip, a rectangular clip, a cylindrical clip, and the like, and correspondingly, the catching groove 1311 may be adapted to the regular or irregular shaped clip such as a triangular clip, a rectangular clip, a cylindrical clip, and the like.

In some embodiments, the unlocking manipulating member 133 fixedly coupled to the locking mating portion 132 may be formed as one ring-shaped integral body with the annular latch 1321. Referring to fig. 2, when the first part 110 and the second part 120 need to be connected to each other, the locking portion 131 is located in the annular overall space (i.e., the space surrounded by the unlocking operation member 133 and the annular latch 1321), the movement of the unlocking operation member 133 can drive the annular latch 1321 to move together, and the annular latch 1321 can move into the latch slot 1311 (i.e., the first position) to be latched, so that the first part 110 and the second part 120 are connected to each other.

In some embodiments, the unlocking manipulating member 133 and the locking mating portion 132 can be fixedly connected by clamping, welding, gluing, or the like. In some embodiments, the unlocking manipulating member 133 and the locking fitting 132 may be integrally formed, for example, the unlocking manipulating member 133 and the locking fitting 132 may be integrally formed by casting, injection molding, 3D printing, or the like.

Further, referring to fig. 2 and 3, the connection assembly 130 may include an annular housing 134. The unlocking operation member 133 is located outside the annular housing 134, the annular clamping block 1321 is located inside the annular housing 134, and the annular clamping block 1321 can be driven to move from the first position to the second position by the movement of the unlocking operation member 133 relative to the annular housing 134. Specifically, as shown in fig. 3, when a pressing force is applied to the unlocking operation member 133 from right to left, the unlocking operation member 133 may be moved from right to left in the radial direction of the annular housing 134 to bring the annular latch 1321 from the first position to the second position. By moving the annular cartridge 1321 from the first position to the second position, the annular cartridge 1321 may be separated from the card slot 1311, and the locking portion 131 and the locking mating portion 132 are not mated any more, thereby achieving the purpose of separating the first portion 110 and the second portion 120 from each other.

In some embodiments, when the first part 110 and the second part 120 are connected to each other, the annular latch 1321 moves from the first position to the second position, when the annular latch 1321 is located at the second position, the annular latch 1321 does not block the locking portion 131 from entering the annular space formed by the unlocking operation member 133 and the annular latch 1321, so that the locking portion 131 can smoothly enter the space, and then the annular latch 1321 returns to the first position from the second position under the driving of the unlocking operation member 133 to be latched with the latch 1311, so that the first part 110 and the second part 120 are connected to each other.

With continued reference to fig. 2 and 3, in some embodiments, the connecting assembly 130 may further include a spring 135, the spring 135 is located in the annular housing 134 and has one end connected to the unlocking operation member 133, and the unlocking operation member 133 may bring the annular latch 1321 back to the first position from the second position under the action of the spring to be latched with the latch 1311. In some embodiments, the connecting assembly 130 may further include a support housing 136, and the support housing 136 may provide support for the spring 135, so that an end of the spring 135, which is not connected to the unlocking manipulating member 133, can be abutted, so that the spring 135 can be compressed to generate an elastic force. For example, at least a portion of the support housing 136 (e.g., the protrusion 1361 shown in fig. 2) may be located in the annular housing 134, and the protrusion 1361 may abut against the spring 135, so that the spring 135 can be compressed to generate an elastic force to make the unlocking operation member 133 bring the annular latch 1321 back to the first position from the second position.

The process of coupling and uncoupling the first portion 110 and the second portion 120 of the endoscopic device 100 to and from each other (i.e., the process of attaching and detaching the first portion 110 to and from the second portion) will be described below by way of example in conjunction with the specific structure of the coupling assembly 130.

When the first portion 110 and the second portion 120 need to be connected to each other, since the unlocking operation member 133 is connected to one end of the spring, when the unlocking operation member 133 is not pressed in a radial direction of the annular housing 134 (for example, in a direction from right to left as shown in fig. 3), the unlocking operation member 133 does not move relative to the annular housing 134, the spring 135 is not compressed, and is in a natural state, at this time, the annular latch 1321 is in the first position, and the annular latch 1321 may limit the entry of the locking portion on the first portion 110 into a space of the annular whole formed by the annular latch 1321 and the unlocking operation member. Therefore, when the operator connects the first section 110 and the second section 120 to each other, the operator first needs to press the unlocking operation member 133 (i.e., apply a pressing force to the unlocking operation member 133) so that the unlocking operation member 133 can move in a radial direction (e.g., a direction from right to left as shown in fig. 3) relative to the annular housing 134, during the movement of the unlocking operation member 133, the spring 135 is compressed, and is in a compressed state, the annular latch 1321 is driven to move from the first position to the second position to ensure that the locking portion 131 can enter the annular integral space formed by the unlocking operation member 133 and the annular latch 1321, when the annular latch 1321 is aligned with the latch slot 1311, the operator can release the unlocking operation member 133 (i.e., stop applying the pressing force to the unlocking operation member 133), and the spring 135 returns to a natural state from the compressed state under the action of its own elastic force, and drives the unlocking manipulating member 133 to move in a radial direction (for example, a left-to-right direction as viewed in fig. 3) relative to the annular housing 134 to drive the annular latch 1321 to return to the first position from the second position, and to latch with the latch slot 1311, thereby connecting the first part 110 and the second part 120 to each other.

When the first portion 110 and the second portion need to be separated from each other, the operator can press the unlocking operation member 133 again to drive the annular latch 1321 to move from the first position to the second position, so that the annular latch 1321 is no longer latched with the latch slot 1311, and the first portion 110 and the second portion 120 can be separated from each other.

When the connecting assembly 130 in the embodiment of the present specification is used to connect the first portion 110 and the second portion 120 of the endoscope apparatus 100, the operator can easily and quickly complete the connection and disconnection (or referred to as assembly and disassembly) between the first portion 110 and the second portion 120 by pressing the unlocking manipulating member 133 by the above operation.

In some embodiments, in order to prevent the endoscope apparatus 100 from being used in a situation where an operator accidentally presses the unlocking operation member 133 or the unlocking operation member 133 is collided and then receives a pressing force to move the locking fitting portion 132 away from the first position and disengage from the locking slot 1311, so that the first portion 110 and the second portion 120 are separated from each other, as shown in fig. 2, the connection assembly 130 in the embodiment of the present specification may further include a safety operation member 137, and the safety operation member 137 may be used to limit the movement of the locking fitting portion 132 from the first position to the second position. In the case where the movement of the lock mating portion 132 is restricted, even if the operator inadvertently presses the unlock operation member 133 or the unlock operation member 133 receives a pressing force due to a collision, the unlock operation member 133 does not move relative to the annular housing 134, and the lock mating portion 132 is always maintained at the first position.

Specifically, the safety operation member 137 is slidable between a third position and a fourth position, and when the safety operation member 137 is located at the third position, the safety operation member 137 abuts against the lock fitting portion 132 to restrict the lock fitting portion 132 from moving from the first position to the second position. When the safety operation member is located at the fourth position, the safety operation member 137 is staggered with the locking coupling portion 132, and the locking coupling portion 132 is no longer limited by the safety operation member 137 and can move from the first position to the second position.

FIG. 4 is a partial schematic structural view of the connection assembly shown in the third position of the safety operating member according to some embodiments of the present disclosure. FIG. 5 is a partial schematic structural view of the connection assembly shown in the fourth position of the safety operating member according to some embodiments of the present disclosure.

As shown in fig. 2, 4 and 5, when the connecting assembly 130 includes the annular housing 134, a sliding slot 1341 is disposed on one side of the annular housing 134 opposite to the unlocking operation member 133, the safety operation member 137 can slide in the sliding slot 1341 along a circumferential direction of the annular housing 134, and positions of the safety operation member 137 in the sliding slot 1341 can include a third position and a fourth position. The third position may be a position where the safety operation member 137 abuts against the lock mating part 132 (for example, a position where the safety operation member 137 shown in fig. 4 is located), and the fourth position may be one or more positions where the safety operation member 137 is completely misaligned with the lock mating part 132 (for example, a position where the safety operation member 137 shown in fig. 5 is located). In fig. 4, the safety operating member 137 is located at the third position, and abuts against the locking mating portion 132 to restrict the locking mating portion 132 from moving from the first position to the second position. In fig. 5, the safety operation member 13 is located at the fourth position, and is offset from the locking mating portion 132, so that the locking mating portion 132 is not restricted by the safety operation member 13 and can move from the first position to the second position.

By way of example only, during actual use of the endoscopic device 100, the safety operation member 137 may be always maintained in the third position, the safety operation member 137 may always limit the locking mating portion 132 to the first position, and the unlocking operation member 133 may not move relative to the annular housing 134, so that the problem that the unlocking operation member 133 is separated from the first portion 110 and the second portion 120 to affect use of the endoscopic device 100 in the case that the unlocking operation member 133 is pressed or collided by an operator carelessly can be avoided.

When the first part 110 and the second part 120 of the endoscope apparatus 100 need to be connected with each other or separated from each other, the safety operation member 137 may be slid to the fourth position, so that the safety operation member 137 and the locking mating portion 132 are completely dislocated, and the locking mating portion 132 is no longer limited to move from the first position to the second position, so that the locking portion 131 can smoothly enter the annular integral space formed by the unlocking operation member 133 and the annular fixture block 1321 to facilitate the connection between the first part 110 and the second part 120, or the annular fixture block 1321 can be completely separated from the fixture slot 1311, so that the first part 110 and the second part 120 are separated from each other.

Since the second portion 120 needs to supply power to the first portion 110, or a control signal generated by the second portion 120 needs to be sent to the first portion 110 to control the first portion 110 to capture an image, an image signal captured by the first portion 110 also needs to be sent to the second portion 120, and then the second portion 120 sends the image signal to a display device for image display. Therefore, it is necessary to establish an electrical connection between the first portion 110 and the second portion 120 to meet the requirements of power transfer, signal transfer, and the like.

In some embodiments, referring to fig. 2, the first portion 110 (the operating handle 111) is provided with a boss 114, and the upper end surface of the boss 114 is provided with a plurality of contact points 1141 for electrically connecting with the second portion 120. Wherein the plurality of contact points 1141 are electrically connected to one or more components (e.g., the operating handle 111, the camera module 113) of the first portion 110. Specifically, referring to fig. 3, the second portion 120 may include a number of contact pins 127, wherein the number of contact pins 127 are electrically connected with the main control circuit board 121 and/or the power supply 123. The electrical connection between the first portion 110 and the second portion 120 is established by the contact mating of the contact pins 127 with the contact points 1141. Thus, the power supply 123 may supply power to the first portion 110 through the plurality of contact pins 127 and the plurality of contact points 1141, the control signal generated by the main control circuit board 121 may also be transmitted to the first portion 110 (e.g., the operating handle 111 and the camera module 113) through the plurality of contact pins 127 and the plurality of contact points 1141, and the image signal collected by the first portion 110 may also be transmitted to the main control circuit board 121 (e.g., the wireless transmitting module) through the plurality of contact points 1141 and the plurality of contact pins 127, and then transmitted to the display device for image display.

In some embodiments, since the locking part 131 is also disposed on the sidewall of the boss 114, when the locking part 131 is mated with the locking mating part 132 to achieve the interconnection of the first part 110 and the second part 120, the contact points 1141 can be contact-coupled with the contact pins 127 to establish the electrical connection between the first part 110 and the second part 120, that is, the interconnection of the first part 110 and the second part 120 can achieve the electrical connection between the first part 110 and the second part 120.

By providing the boss 114 on the first part 110 and providing the contact point and the locking part 131 on the upper end surface and the side wall of the boss 114, respectively, the second part 120 may include a contact latch and a locking fitting 132, respectively. The mutual coupling between the first and

second parts

110 and 120 is accomplished by the mutual coupling of the locking part 131 and the locking coupling part 132, and the electric connection between the first and

second parts

110 and 120 is accomplished by the coupling of the contact point and the contact latch. In some embodiments, the operator can achieve the two functional connections, i.e., the mutual connection and the electrical connection between the first portion 110 and the second portion 120, by only one operation, for example, when the operator connects the locking portion 131 and the locking mating portion 132 to achieve the mutual connection between the first portion 110 and the second portion 120, the contact points 1141 can be in contact coupling with the contact pins 127 to achieve the electrical connection between the first portion 110 and the second portion 120. Specifically, the mating between the locking part 131 and the locking mating part 132 enables the mating between the contact point and the contact latch, or the mating between the contact point and the contact latch enables the mating between the locking part 131 and the locking mating part 132.

In some embodiments, several pins may be provided on the boss 114, which are electrically connected to one or more components (e.g., the operating handle 111, the camera module 113) in the first portion 110. Correspondingly, the second portion 120 may include a socket, which may be disposed on the main control circuit board 121 or electrically connected with the main control circuit board 121. Wherein the receptacle may comprise a number of receptacles into which electrical connections between the first part 110 and the second part 120 may be established by inserting a number of pins.

By means of the plug-in coupling of the pins with the sockets, not only the electrical connection between the first part 110 and the second part 120 can be established, but also the locking part 131 can be positioned when the first part 110 and the second part 120 are connected to each other.

For example only, when the first and

second parts

110 and 120 are connected, in order to ensure that the ring-shaped cartridge 1321 can be snapped into the card slot 1311 when in the first position, the card slot 1311 should be maintained at a position corresponding to the ring-shaped cartridge 1321. The position of the card slot 1311 corresponding to the annular card block 1321 can be understood as the position of the card slot 1311 when the projection of the card slot 1311 on the annular card block 1321 can completely coincide with the annular card block 1321.

In contrast, when the operator places the locking portion 131 into the annular space formed by the unlocking operation member 133 and the annular clamping block 1321, the plurality of pins on the first portion 110 may be inserted into the plurality of insertion holes, so that the positions of the clamping groove 1311 and the annular clamping block 1321 are ensured to correspond to each other while the electrical connection between the first portion 110 and the second portion 120 is established, and the annular clamping block 1321 can be clamped with the clamping groove 1311 when the annular clamping block 1321 is in the first position. When the first part 110 and the second part 120 are connected with each other, the locking part 131 is positioned in a manner of plug-in coupling of the plurality of pins and the plurality of jacks, so that an operator can enable the positions of the clamping groove 1311 and the annular clamping block 1321 to correspond to each other without adjusting the position or the direction of the clamping groove 1311 for many times, the annular clamping block 1321 is quickly clamped in the clamping groove 1311, and the efficiency of the connection between the first part 110 and the second part 120 is improved. In addition, the coupling of a plurality of pins with a plurality of sockets may also increase the reliability of the interconnection between the first portion 110 and the second portion 120 to some extent.

In some embodiments, referring to fig. 2, the fixture block 1362 may be disposed on the support housing 136, and the fixture block slot adapted to the fixture block 1362 is disposed on the sidewall of the protruding platform 114 of the first portion 110, when the fixture block 1362 is located in the fixture block slot 1142, the locking portion 131 (i.e., the fixture slot 1311) is located at a position corresponding to the locking mating portion 132 (i.e., the annular fixture block 1321), so that the annular fixture block 1321 can be engaged with the fixture slot 1311 when the annular fixture block 1321 is located at the first position, thereby achieving the mutual connection between the first portion 110 and the second portion 120.

For example only, when an operator connects the first portion 110 and the second portion 120, the operator may press the unlocking operation member 133, and when the operator places the locking portion 131 (the boss 114) in the annular space formed by the unlocking operation member 133 and the annular latch 1321, the annular latch 1321 may be first latched to the annular latch 1362, so that the position of the annular latch 1311 corresponds to the annular latch 1321, and when the operator releases the unlocking operation member 133, the annular latch 1321 may be moved to the first position to be latched to the annular latch 1311.

By providing the latching protrusion 1362 to be latched to the latching groove 1142, the locking portion 131 can be positioned when the first and

second portions

110 and 120 are connected, so that the operator can quickly position the locking portion 131 (the latching groove 1311) at a position corresponding to the annular latching protrusion 1321, thereby improving the efficiency of connecting the first and

second portions

110 and 120. In addition, the engagement between the locator card 1362 and the locator card slot 1142 can effectively limit the relative rotation between the first portion 110 and the second portion 120, thereby increasing the reliability of the connection between the first portion 110 and the second portion 120.

The connecting assembly 130 of the embodiment of the present specification not only can reliably connect the first part 110 and the second part 120 of the endoscope apparatus 100 together, but also can be simply and quickly connected and disconnected, and the operator can easily and quickly complete the connection and disconnection of the first part 110 and the second part 120 mainly by pressing the unlocking manipulating member 133 provided on the annular housing 134. In particular, when the endoscope apparatus 100 needs to be charged, the operator can easily separate the second portion 120 from the first portion 110 to charge the second portion 120, and can also connect another second portion 120 having a sufficient amount of power to the first portion 110 without delaying the use of the endoscope apparatus 100. In addition, the annular housing 134 of the connecting assembly 130 is further provided with a safety operating member 137, and the locking mating part 132 (the annular clamping block 1321) can be limited from moving away from the first position by the safety operating member 137 in the using process of the endoscope device, so that the problem that the first part 110 and the second part 120 are separated and the use of the endoscope device is influenced because the locking mating part 132 moves away from the first position is avoided. In addition, by disposing the unlocking operation member 133 and the safety operation member 137 on the annular housing 134, too much space of the annular housing 134 is not occupied, and the space utilization of the annular housing 134 can be improved, so that the structure of the connecting assembly 130 can be more compact, and the connection between the first part 110 and the second part 120 can be more compact.

The embodiment of the specification also provides an endoscope system. FIG. 6 is a schematic block diagram of an endoscopic system according to some embodiments of the present description.

Specifically, referring to fig. 1, the first portion 110 of the endoscope apparatus 100 may be used to capture an image signal, and the first portion 110 may include at least an operation handle 111, an insertion portion 112, and a camera module 113 provided at a front end of the insertion portion 112. The description of the related structure of the first portion 110 and how the first portion 110 acquires the image signal may refer to the related description above.

After the image signal is captured by the first portion 110, the image signal can be transmitted to the display device 200 through the second portion 120. The description of how the image signal is transmitted from the first portion 110 to the second portion 120 may refer to the above description about the electrical connection of the first portion 110 and the second portion 120.

In some embodiments, referring to fig. 2, the second portion 120 may include at least a master circuit board 121, a housing 125, and a mounting plate 126. The main control circuit board 121 may be located in an accommodating space formed by the housing 125 and the mounting plate 126. In this embodiment, the mounting plate 126 may be used to fixedly connect with the connecting assembly 130. Specifically, the connecting assembly 130 may further include a mounting housing 138, the mounting housing 138 is fixedly connected or integrally formed with the annular housing 134 and the support housing 136, and the mounting housing 138 is fixedly connected to the mounting plate 126, so that the locking mating part 132, the unlocking operation member 133 and other parts of the connecting assembly 130 except for the locking part 131 can be disposed on the second portion 120. In some embodiments, the mounting housing 138 may be fixedly coupled to the mounting plate 126 by various means such as bolting, gluing, welding, etc. More details about the main control circuit board 121 have been described above, and are not described herein again.

In some embodiments, referring to fig. 6, the display device 200 may include an image processing module (not shown) and a display 201. The image processing module can process the image signal from the second portion 120 and generate a corresponding image to be displayed on the display 201, so that an operator (e.g., a doctor or a machine maintenance person) can observe the image in the patient's body cavity or the machine cavity through the display device, thereby helping the operator to make a more accurate judgment on the patient's condition or machine malfunction. In some embodiments, the display 201 of the display device 200 may be a touch display screen, and the operator may input an operation instruction through the touch display screen, wherein the operation instruction may include, but is not limited to, adjusting the brightness of the field of view of the camera module 113, adjusting the bending angle or direction of the insertion portion 112, capturing a saved image, and the like. The operation instruction may be transmitted to the second portion 120, and the main control circuit board 121 may generate a control signal based on the operation instruction and transmit the control signal to the first portion 110 to perform a corresponding operation. The description of how the control signal is transmitted from the second portion 120 to the first portion 110 may refer to the above description of the first portion 110 being electrically connected to the second portion 120.

In some embodiments, in order to transmit an image signal from the endoscope apparatus 100 to the display apparatus 200 or an operation instruction input by a user on the touch display screen to the endoscope apparatus 100, a communication connection can be made between the display apparatus 200 and the endoscope apparatus 100, that is, between the display apparatus 200 and the second portion 120. In some embodiments, the communication connection between the display device 200 and the second portion 120 may be a wired connection or a wireless connection.

In some scenarios (e.g., where the working environment is narrow or where there are many people), the flexibility and length of the cable (e.g., cable) connecting the display device 200 and the second portion may limit the ease of operation of the endoscopic device during use when there is a wired connection between the display device 200 and the second portion 120. Therefore, the communication connection between the display device 200 and the second portion 120 is preferably a wireless connection.

For example only, a wireless transmission module may be provided on the main control circuit board 121, through which the image signal may be transmitted to the display device. Taking bluetooth connection as an example, the wireless transmitting module on the main control circuit board is a bluetooth transmitting module, and the display device 200 has a bluetooth receiving module capable of being connected with the bluetooth transmitting module in a matching manner. The wireless connection between the display device 200 and the endoscope device 100 can be realized through the pairing connection between the bluetooth transmitting module and the bluetooth receiving module.

In some embodiments, the second portion 120 may also be used to provide power to the first portion 110. Specifically, as shown in fig. 2, the power supply 123 is further accommodated in the accommodating space between the housing 125 and the mounting plate 126. In some embodiments, the main control circuit board 121 is further provided with a power management module 124 electrically connected to a power supply. For more description of the power supply 123, the power management module 124, and how the power supply 123 supplies power to the first portion, reference may be made to the related description above.

In some embodiments, the power supply 123 can also be used to power the display device 200 when the display device 200 is wired to the endoscopic device 100.

In some embodiments, when a charging interface (e.g., a USB interface) may be provided on the second portion 120, the charging interface may be connected to a corresponding power output (supply) device through a charging wire (e.g., a USB wire) to charge the power supply 123.

By connecting the first portion 110 to the second portion 120 using the connection assembly 130 and having the power source 123 disposed within the second portion 120, the second portion 120 can be easily removed to charge the power source 123 in the event that the power source 123 is low on power, and the first portion 110 can be connected to a second portion having a sufficient amount of power from another power source, thereby resolving the problem of cruising of the endoscopic device 100 without delaying use of the endoscopic device 100.

In some embodiments, to facilitate charging of the power source 123, a charging jack 202 may be provided on the display device 200, and the power source 123 may be charged directly on the display device 200 through the charging jack. For example, the second portion 120 is provided with a charging plug electrically connected to the power source 123, and the charging plug can be inserted into the charging jack 202 to charge the power source 123. For another example, the second portion 120 is provided with a charging interface, which can be connected to the charging jack 202 by wire, so that the power supply 123 can be charged.
