Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and in particular to an endoscope and an endoscope system. Background Art

[0002] An endoscope generally includes a connecting portion, an operating portion, and an insertion portion, which are connected in sequence. The connecting portion is used to connect to the light source emission end of the endoscope system, the insertion portion is inserted into the patient's body for corresponding image acquisition and observation, and the operating portion is used to control the insertion portion to bend or straighten accordingly.

[0003] The operating part and the insertion part are connected by a flexible rope. The transmission mechanism is driven by twisting the knob on the operating part to drive the flexible rope to perform telescopic movement, thereby controlling the bending of the bending part of the insertion part to achieve the deflection of the head end of the insertion part.

[0004] However, after the frequency of use of the operating part increases, there is a certain probability that the rotation or transmission mechanism will fail, resulting in difficulty in pulling the flexible rope. At this time, the bent portion of the insertion part is still in a bent state, which also causes the head end to be in a deflected state, making it difficult for the insertion part to be removed from the patient's body, posing a certain safety risk. Summary of the invention

[0005] The object of the present invention is to provide an endoscope and an endoscope system, which are intended to solve the problem that the insertion portion of the endoscope is difficult to restore from a bent state to a straight state due to failure of the operating portion.

[0006] To achieve the above object, the technical solution adopted by the present invention is:

[0007] In a first aspect, an embodiment of the present application provides an endoscope, comprising:

[0008] An operating part, the operating part comprising an operating body, a knob, a first transmission member disposed in the operating body and connected to the knob, and an unlocking button assembly movably connected to the operating body;

[0009] An insertion part, the insertion part comprising an insertion body connected to the operating body and the second transmission member disposed in the insertion body, the second transmission member being detachably connected to the first transmission member;

[0010] Wherein, the unlock button assembly is configured to separate the second transmission member and the first transmission member in a pressed state.

[0011] Beneficial effects of the present invention: The endoscope provided by the present invention is additionally provided with an unlocking button assembly for separating the second transmission member from the first transmission member. Specifically, the first transmission member and the second transmission member are connected in a detachable connection manner, and when the unlocking button assembly is pressed, the first transmission member and the second transmission member can be unlocked and separated, thereby releasing the restraint on the force of the insertion portion, so that the insertion portion can be restored from a bent state to a straight state, so that the operator can subsequently remove the insertion portion from the patient's body.

[0012] In some embodiments, the unlocking button assembly includes a button portion movably connected to the operating body and an unlocking portion adapted to the button portion, and the unlocking portion separates the first transmission member and the second transmission member when the button portion is pressed.

[0013] By adopting the above technical solution, the button part is the object to be pressed, and the unlocking part is the part adapted to be linked with the button part. That is, when the operator presses the button part, the unlocking part can be linked to realize the separation of the first transmission member and the second transmission member.

[0014] In some embodiments, the unlocking portion includes a buckle body with a hollow structure and a slider slidably connected to the buckle body, the buckle body having a first end and a second end arranged opposite to the first end, one of the first transmission member and the second transmission member is snap-connected to the first end, and / or the other of the first transmission member and the second transmission member is snap-connected to the second end, and the slider slides toward the first end and / or the second end under the action of pressing the button portion to disengage the first transmission member or the second transmission member from the buckle body.

[0015] By adopting the above technical solution, the first transmission member is detachably connected to the second transmission member through the buckle body. At the same time, according to actual needs, one or both of the first transmission member and the second transmission member can be detachably connected to the first end and / or the second end of the buckle body, and then the slider slides in the buckle body to separate the first transmission member or the second transmission member from the buckle body.

[0016] In some embodiments, one end of the first transmission member is connected to the first end, one end of the second transmission member is placed in the buckle body and is clamped to the second end, and the slider slides toward the second end under the pressing action of the button portion to disengage the second transmission member from the second end.

[0017] By adopting the above technical solution, the first end of the buckle body is connected to the first transmission member, and the second end of the buckle body is detachably connected to the second transmission member. When the button part is pressed, the slider slides in the buckle body and slides toward the second end to separate the second transmission member from the second end.

[0018] In some embodiments, the second end includes at least two claws, each of which is arranged at intervals with the central axis of the buckle body as the center, and the second transmission member includes a clamping block, each of which is clamped to each of the claws, and the slider slides toward each of the claws under the action of pressing the button part to disengage the clamping block from each of the claws.

[0019] By adopting the above technical solution, the second end is connected to the clamping block at the second end through each clamping claw to form a corresponding connection relationship, and when the slider slides in the buckle body and slides toward the second end, each clamping claw loosens the clamping block.

[0020] In some embodiments, the unlocking part also includes a base that is inserted into the buckle body along the pressing direction, with one end of the base being sleeved on the base and the other end of the driving member being slidably connected to the button part, the driving member being connected to the slider, and when the driving member slides relative to the base along the pressing direction, it drives the slider to slide in the buckle body.

[0021] By adopting the above technical solution, the driving member slides relative to the base in the pressing direction, and during the sliding process, drives the slider to slide in the buckle body toward the second direction. That is, the driving member converts the force in the pressing direction into the driving force of the slider in the buckle body.

[0022] In some embodiments, the driving member includes a sleeve mounted on the base and a driving portion disposed on the sleeve, one end of the sleeve is slidably connected to the button portion, and the driving portion is used to drive the slider to slide in the buckle body.

[0023] By adopting the above technical solution, when the sleeve slides relative to the base along the pressing direction, the driving part transmits the force to the sliding block, so that the sliding block slides in the buckle body, meeting the requirement of separating the second transmission member.

[0024] In some embodiments, the driving part includes a connecting rod having one end hinged to the sleeve and the other end hinged to the slider; or,

[0025] The driving part comprises a wedge block, the wedge block is connected to the outer wall of the sleeve, the wedge block has a wedge surface, and the sliding block is slidably connected to the wedge surface.

[0026] By adopting the above technical solution, the driving part includes a connecting rod, and the driving effect of the connecting rod is used to meet the needs of pushing out or pulling back the slider; or, the driving part includes a wedge block, and the wedge surface of the wedge block is adapted to the slider, which can also achieve the pushing out or pulling back of the slider.

[0027] In some embodiments, the unlocking portion further includes a reset member, which is sleeved on the base, and one end of the reset member abuts against the base and the other end abuts against the sleeve.

[0028] By adopting the above technical solution, the reset member is used to reset the sleeve so that the sleeve is in the initial position, and also provides corresponding pulling force for the slider to return to the initial position.

[0029] In some embodiments, the unlocking portion further includes an anti-accidental touch structure, and the anti-accidental touch structure is used to limit the movement of the driving member relative to the base.

[0030] By adopting the above technical solution, the anti-mistouch structure is used to reduce the probability of relative movement of the driving member relative to the base under unconventional operations, that is, to reduce the probability of separation of the second transmission member from the first transmission member under unconventional operations.

[0031] In some embodiments, there are multiple unlock button assemblies, and each of the unlock button assemblies is arranged on the operating body at intervals with the central axis of the operating body as the center. Each of the unlock button assemblies is configured to unlock one or more of the second transmission members of the insertion part, and each of the unlock button assemblies can move synchronously or asynchronously relative to the operating body.

[0032] By adopting the above technical solution, the unlocking button assembly can be configured with one or more second transmission members of the unlocking insertion part according to actual use requirements. At the same time, each unlocking button assembly can be independently operated asynchronously, or synchronously operated and move relative to the operating body.

[0033] In some embodiments, there are multiple unlocking parts, and each unlocking part is compatible with the same button part.

[0034] By adopting the above technical solution, a button portion can be pressed once to allow multiple unlocking portions to unlock and separate the corresponding first transmission member and second transmission member.

[0052] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0054] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0055] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0056] Generally, an endoscope includes a connection part, an operation part, and an insertion part. The connection part is connected to the light outlet of the endoscope system to transmit the light source to the insertion part. The operation part is for medical personnel to operate by hand and adjust the bending degree of the insertion part. The insertion part is the part inserted into the patient's body. The insertion part includes a flexible bending part that can be adjusted by the operation part and a head end connected to the bending part. The head end is hard and cannot be bent.

[0057] In addition, a transmission mechanism such as a chain is provided in the operating part, which is connected to the knob on the operating part. When the medical staff turns the knob, the chain can be driven to pull the flexible rope of the insertion part, so that the bending part changes from a straight state to a bent state. However, in the actual operation process, there is still a very small probability that the knob and the corresponding transmission mechanism fail, resulting in difficulty in pulling the flexible rope, or even stuck. In this way, the flexible rope cannot be pulled, and the bending part of the insertion part is always in a bent state and cannot be restored to a straight state, which greatly increases the difficulty for medical staff to remove the insertion part from the patient's body.

[0058] In view of this, the present application provides an endoscope, in which the connection between the first transmission member of the operating part and the second transmission member of the insertion part is changed to a detachable connection. At the same time, an unlocking button assembly is added, that is, the first transmission member and the second transmission member can be unlocked and separated by pressing, thereby effectively solving the problem that the insertion part is difficult to restore to a straight state due to the failure of the rotating member of the operating part.

[0059] First, please refer to Figures 1 to 3 An embodiment of the present application provides an endoscope 100 , including an operating portion 10 and an insertion portion 20 .

[0060] The operating part 10 includes an operating body 11, a knob 12, a first transmission member 13 disposed in the operating body 11 and connected to the knob 12, and an unlocking button assembly 14 movably connected to the operating body 11;

[0061] The inserting portion 20 includes an inserting body 21 connected to the operating body 11 and a second transmission member 22 disposed in the inserting body 21. The second transmission member 22 is detachably connected to the first transmission member 13.

[0062] The unlock button assembly 14 is configured to separate the second transmission member 22 and the first transmission member 13 when pressed.

[0063] It can be understood that the operating part 10 is a part for medical personnel to hold and operate in order to switch the insertion part 20 between a straight state and a curved state. Specifically, the operating body 11 is the main part of the operating part 10 and is also the part for medical personnel to hold in their hands. The knob 12 is movably connected to the operating body 11. For example, the knob 12 can rotate around the axis relative to the operating body 11. Usually, a part of the knob 12 is exposed outside the operating body 11 and a part is inserted into the inside of the operating body 11. The part of the knob 12 that is inserted into the inside of the operating body 11 is connected to the first transmission member 13, that is, when the knob 12 rotates around the axis, the first transmission member 13 is driven, which is similar to the transmission form of a gear driving a chain. Therefore, the structural form of the first transmission member 13 includes but is not limited to a chain, a belt, a chain belt, etc.

[0064] The unlock button assembly 14 is a part that can move relative to the operating body 11, and specifically, it can move relative to the operating body 11 in a pressing manner. Here, the pressing manner can be that the unlock button assembly 14 completes the pressing action "straight up and down" in the pressing direction, or the unlock button assembly 14 completes the pressing action by twisting.

[0065] The insertion body 21 is the main part of the insertion part 20, which plays the corresponding bearing and deformation functions. In order to adapt to its movement inside the human body, the insertion body 21 should be flexible. Therefore, the bending state of the insertion body 21 referred to in this application is the bending behavior of the insertion body 21 under the pulling operation of the operating part 10, rather than the bending behavior of the insertion body 21 under non-pulling action due to its own material characteristics. Driven by the first transmission member 13 of the operating part 10 to the second transmission member 22, the insertion body 21 can switch between a straight state and a bent state. Here, the structural form of the second transmission member 22 includes but is not limited to a steel wire rope, a chain, a rope belt, etc. At the same time, the number of the second transmission member 22 can also be one or more to meet the bending needs of the insertion body 21 with multiple degrees of freedom in space.

[0066] The connection relationship between the first transmission member 13 and the second transmission member 22 can be a direct connection or an indirect connection.

[0067] For example, when the first transmission member 13 and the second transmission member 22 are directly connected, that is, there are hook structures similar to mutual latching or plug-in structures on the first transmission member 13 and the second transmission member 22, the direct connection between the two can be destroyed under the pressing action of the unlocking button assembly 14, thereby unlocking the first transmission member 13 and the second transmission member 22, so that the two are separated at the connection.

[0068] For example, a first hook is provided on one end of the first transmission member 13, and a second hook engaged with the first hook is provided on one end of the second transmission member 22. The unlocking button assembly 14 is similar to a button structure movably connected to the operating body 11, and a push-up structure such as a push-up column is provided on the button structure. Under the action of external force, the button structure drives the push-up structure to act on the connection between the first hook and the second hook, so that the two hooks are unhooked and the first transmission member 13 is separated from the second transmission member 22.

[0069] For another example, when the first transmission member 13 and the second transmission member 22 are indirectly connected, that is, the first transmission member 13 and the second transmission member 22 are connected in a detachable manner through an additional mechanism or structure, when the unlocking button assembly 14 is pressed, the additional mechanism or structure can be triggered to separate the first transmission member 13 and the second transmission member 22.

[0070] For example, a first hook is provided on one end of the first transmission member 13, and a second hook is provided on one end of the second transmission member 22. The unlocking button assembly 14 includes a button structure movably connected to the operating body 11, and a third hook and a fourth hook are provided on the button structure. The first hook is connected to the third hook, and the second hook is connected to the second hook. Under the action of external force, the button structure drives the third hook and the fourth hook, so that the connection between the third hook and the first hook, and / or the connection between the fourth hook and the second hook becomes loose and separated.

[0071] Of course, the unlocking button assembly 14 only needs to be in a detachable connection relationship with one of the first transmission member 13 or the second transmission member 22 .

[0072] In summary, when medical personnel operate the endoscope 100 to obtain corresponding image information in the patient's body and perform related surgical operations, the medical personnel can drive the first transmission member 13 by rotating or shaking the knob 12, and then the second transmission member 22 drives the insertion body 21 to bend or straighten. Once the knob 12 is stuck in rotation or shaking and the first transmission member 13 is blocked, causing the second transmission member 22 to lose the pulling control of the insertion body 21, the medical personnel can disconnect the first transmission member 13 and the second transmission member 22 by pressing the unlocking button assembly 14, so that the insertion body 21 that has been pulled and bent can be released, thereby restoring it to the initial straight state. In this way, after completing the corresponding image acquisition and surgical operations, the insertion part 20 can be smoothly removed from the patient's body.

[0073] The endoscope 100 provided by the present invention is additionally provided with an unlocking button assembly 14 for separating the second transmission member 22 and the first transmission member 13. Specifically, the first transmission member 13 and the second transmission member 22 are connected in a detachable connection manner, and when the unlocking button assembly 14 is pressed, the first transmission member 13 and the second transmission member 22 can be unlocked and separated, thereby releasing the force restraining the insertion portion 20, so that the insertion portion 20 can be restored from a bent state to a straight state, so that the operator can subsequently remove the insertion portion 20 from the patient's body.

[0074] Please refer to Figures 4 to 7 In some embodiments, the unlocking button assembly 14 includes a button portion 141 movably connected to the operating body 11 and an unlocking portion 142 adapted to the button portion 141, and the unlocking portion 142 and the button portion 141 are pressed to separate the first transmission member 13 and the second transmission member 22.

[0075] It can be understood that the button portion 141 is an object to be pressed.

[0076] Specifically, the button portion 141 is a button structure formed on the operating body 11, and moves relative to the operating body 11 under a pressing action. Optionally, the button portion 141 moves relative to the operating body 11 along the radial direction of the operating body 11.

[0077] The unlocking portion 142 is a portion adapted to be linked with the button portion 141 , and is connected to the button portion 141 . Furthermore, when the button portion 141 moves relative to the operating body 11 under the action of pressing, the unlocking portion 142 can be linked.

[0078] For example, the unlocking portion 142 is a pushing structure such as a pushing rod or a pushing block provided on the button portion 141. The pushing structure moves with the button portion 141 relative to the operating body 11. At this time, the first transmission member 13 and the second transmission member 22 are directly connected in a detachable manner. For example, one end of the first transmission member 13 is clamped or plugged into one end of the second transmission member 22. Driven by the button portion 141, the pushing structure abuts against the first transmission member 13 or the second transmission member 22, so that the connection between the two transmission members is subjected to shear force and separated.

[0079] By way of example, the unlocking portion 142 may also be a snap-fitting structure provided on the button portion 141, which may be selectively snap-fitted to the first transmission portion and / or the second transmission portion, and, driven by the button portion 141, the connection between the snap-fitting structure and the first transmission portion and / or the second transmission portion is subjected to shear force and separated.

[0080] By way of example, the unlocking portion 142 may include a magnetic structure, which may be a magnetically controllable component such as a coil, and the first transmission portion and / or the second transmission portion has a magnetic portion that is magnetically attracted to the magnetic structure. Under the abutment of the button portion 141, the magnetic structure may switch between a power-on state and a power-off state, that is, the magnetic structure is magnetically attracted to the first transmission portion and / or the second transmission portion in the power-on state, and is separated from the first transmission portion and / or the second transmission portion in the power-off state.

[0081] In this way, when the knob 12 fails and loses control of the first transmission member 13, the medical staff can press the button to link the unlocking part 142, so that the connection between the first transmission member 13 and the second transmission member 22 is disconnected, causing the second transmission member 22 in the insertion part 20 to lose the pulling effect. At this time, the insertion part 20 can be restored from the bent state to the straight state.

[0082] Please refer to Figures 4 to 7In some embodiments, the unlocking portion 142 includes a buckle body 1421 with a hollow structure and a slider 1422 slidably connected to the buckle body 1421, the buckle body 1421 has a first end 142a and a second end 142b arranged opposite to the first end 142a, one of the first transmission member 13 and the second transmission member 22 is snap-connected to the first end 142a, and / or the other of the first transmission member 13 and the second transmission member 22 is snap-connected to the second end 142b, and the slider 1422 slides toward the first end 142a and / or the second end 142b under the action of pressing the button portion 141 to disengage the first transmission member 13 or the second transmission member 22 from the buckle body 1421.

[0083] It can be understood that the first end 142a and the second end 142b are two ends of the buckle body 1421 that are oppositely arranged, and are also used to connect with the first transmission member 13 and the second transmission member 22. In terms of connection selection, the first transmission member 13 can be selectively connected to the first end 142a or the second end 142b by snapping, and the second transmission member 22 can be connected to the second end 142b or the first end 142a by snapping, so that at least one of the first transmission member 13 and the second transmission member 22 is connected to the buckle body 1421 by snapping.

[0084] Here, the transmission member and the buckle body 1421 can be connected in a manner that a clamping structure is provided on the first end 142a and / or the second end 142b, and a clamping adapting structure adapted to the clamping structure is provided on the transmission member. For example, a claw 1423 structure is provided on the first end 142a and / or the second end 142b, and a clamping block 221 adapted to the claw 1423 structure is provided on the transmission member.

[0085] The slider 1422 can slide relative to the buckle body 1421 during the pressing process of the button portion 141 relative to the operating body 11, and can slide toward the first end 142a and / or the second end 142b of the buckle body 1421 according to actual use requirements. For example, when one slider 1422 is provided in the buckle body 1421, the slider 1422 can slide toward the first end 142a or the second end 142b of the buckle body 1421 driven by the button portion 141; and when two sliders 1422 are provided in the buckle body 1421, the two sliders 1422 can slide toward the first end 142a or the second end 142b of the buckle body 1421 respectively driven by the button portion 141.

[0086] Here, the slider 1422 can directly act on the end of the first transmission member 13 or the end of the second transmission member 22 by directly pushing, so that the transmission member is separated from the buckle body 1421, or the slider 1422 can also increase the outer diameter of the buckle body 1421 when sliding in the buckle body 1421 with a hollow structure, so as to separate the transmission member from the buckle body 1421.

[0087] For example, an opening connected to the outside is provided at the first end 142a and / or the second end 142b of the buckle body 1421, and a first buckle is arranged on the hole wall of the opening, and a second buckle engaged with the first buckle is provided on the first transmission member 13 or the second transmission member 22. At this time, the slider 1422 slides toward the second buckle driven by the button portion 141, and the second buckle is disengaged from the first buckle by pushing, so that the first transmission member 13 or the second transmission member 22 is separated from the buckle body 1421.

[0088] For example, a plurality of clamping arms are formed on the first end 142a and / or the second end 142b of the buckle body 1421, and the clamping arms are arranged at intervals with the central axis of the buckle body 1421 as the center, that is, a gap is formed between two adjacent clamping arms, and a block is provided on the first transmission member 13 or the second transmission member 22, which extends into the buckle body 1421 and is clamped to each clamping arm. At this time, the slider 1422 slides toward the block driven by the button portion 141, and the outer diameter of the buckle body 1421 is increased by pushing the clamping arm, thereby increasing the gap between the clamping arms until the block can be removed from the buckle body 1421, and the first transmission member 13 or the second transmission member 22 is separated from the buckle body 1421.

[0089] In summary, the first transmission member 13 is detachably connected to the second transmission member 22 through the buckle body 1421. At the same time, according to actual needs, one or both of the first transmission member 13 and the second transmission member 22 can be detachably connected to the first end 142a and / or the second end 142b of the buckle body 1421, and then the slider 1422 slides in the buckle body 1421 to separate the first transmission member 13 or the second transmission member 22 from the buckle body 1421.

[0090] Specifically, please refer to Figure 4 In some embodiments, one end of the first transmission member 13 is connected to the first end 142a, one end of the second transmission member 22 is placed in the buckle body 1421 and is clamped to the second end 142b, and the slider 1422 slides toward the second end 142b under the action of pressing the button portion 141 to disengage the second transmission member 22 from the second end 142b.

[0091] It can be understood that one end of the first transmission member 13 can be connected to the first end 142a by means including but not limited to threaded connection, snap connection, magnetic connection, etc.

[0092] One end of the second transmission member 22 is connected to the inner wall of the buckle body 1421 by means of a snap connection.

[0093] Here, the slider 1422 can directly act on the end of the second transmission member 22 by directly pushing, so that the second transmission member 22 is separated from the buckle body 1421, or the slider 1422 can also slide in the buckle body 1421 with a hollow structure to increase the outer diameter of the buckle body 1421, so that the second transmission member 22 is separated from the buckle body 1421.

[0094] In summary, by separating the second end 142b of the buckle body 1421 from the second transmission member 22, the probability of the buckle body 1421 being pulled by the second transmission member 22 and impacting or colliding with the insertion body 21 can be reduced, thereby providing a certain degree of protection for the insertion portion 20.

[0095] Please refer to Figures 4 to 7 In some embodiments, the second end 142b includes at least two claws 1423, and each claw 1423 is arranged at intervals with the central axis of the buckle body 1421 as the center. The second transmission member 22 includes a clamping block 221, and each clamping block 221 is clamped to each claw 1423. The slider 1422 slides toward each claw 1423 under the action of pressing on the button portion 141 to disengage the clamping block 221 from each claw 1423.

[0096] It can be understood that in the initial state, when the slider 1422 has not slid toward the second end 142b, each claw 1423 limits the clamping block 221 in the buckle body 1421, and when the slider 1422 slides toward the second end 142b driven by the button portion 141, the slider 1422 pushes against the inner wall of each claw 1423, so that the gap between each claw 1423 increases, thereby increasing the inner diameter of the second end 142b of the buckle body 1421, until each claw 1423 can no longer limit the clamping block 221, and the clamping block 221 escapes from the buckle body 1421.

[0097] Optionally, each claw 1423 is gathered toward the distal end of the second transmission member 22, so that the outer diameter of the second end 142b of the buckle body 1421 is smaller than the outer diameter of the first end 142a. In this way, the sliding smoothness of the slider 1422 in the buckle body 1421 can be met without changing the appearance of the slider 1422. At the same time, the each claw 1423 at the second end 142b can be separated from the clamping block 221 of the second transmission member 22.

[0098] Please refer to Figures 4 to 7 In some embodiments, the unlocking portion 142 also includes a base 1424 that is inserted into the buckle body 1421 along the pressing direction, and a driving member 1425 with one end mounted on the base 1424 and the other end slidably connected to the button portion 141. The driving member 1425 is connected to the slider 1422, and when the driving member 1425 slides relative to the base 1424 along the pressing direction, it drives the slider 1422 to slide in the buckle body 1421.

[0099] It can be understood that the pressing direction is the direction of applying force to the button portion 141. Optionally, the pressing direction is along the radial direction of the operating body 11, that is, a direction perpendicular or approximately perpendicular to the arrangement direction of the second transmission member 22 or the first transmission member 13. Here, the pressing direction is parallel to the axial direction of the base 1424.

[0100] The base 1424 and the buckle body 1421 maintain a relatively static relationship, and the driving member 1425 can slide relative to the base 1424 under the pressing action of the button part 141, that is, the driving member 1425 transmits the force along the pressing direction to the force of the slider 1422 in the sliding direction in the buckle body 1421.

[0101] Thus, in the pressing direction, the driving member 1425 slides relative to the base 1424 , and during the sliding process, drives the slider 1422 to slide toward the second direction in the buckle body 1421 , that is, the transmission direction of the force is changed by the driving member 1425 .

[0102] Please refer to Figure 6 and Figure 7 In some embodiments, a slide groove 141 a adapted to the driving member 1425 is provided on the button portion 141 .

[0103] It can be understood that the button portion 141 can slide relative to the operating body 11 in the radial direction of the operating body 11, and the driving member 1425 can move relative to the operating body 11 along the axial direction of the operating body 11. Therefore, it is necessary to use the sliding groove 141a to limit the sliding formation of the driving member 1425. Here, the groove extension direction of the sliding groove 141a should be consistent with the sliding direction of the driving member 1425.

[0104] In this way, the slide groove 141 a on the button portion 141 is used to limit the relative sliding of the driving member 1425 relative to the button portion 141 , that is, the relative sliding of the slider 1422 relative to the buckle body 1421 is limited.

[0105] In other embodiments, in order to prevent the button portion 141 from being separated from the driving member 1425, a wedge block or a wedge groove may be provided in the slide groove 141a, and at the same time, a corresponding wedge groove or a wedge block may be provided at the end of the driving member 1425.

[0106] Please refer to Figures 6 to 8 In some embodiments, the driving member 1425 includes a sleeve 14251 sleeved on the base 1424 and a driving portion 14252 provided on the sleeve 14251, one end of the sleeve 14251 is slidably connected to the button portion 141, and the driving portion 14252 is used to drive the slider 1422 to slide in the buckle body 1421.

[0107] It can be understood that the sleeve 14251 slides in the axial direction relative to the base 1424 , and the sleeve 14251 and the base 1424 are coaxially arranged or approximately coaxially arranged. At the same time, the sleeve 14251 also slides relatively to the button portion 141 .

[0108] The driving portion 14252 slides with the sleeve 14251 relative to the base 1424 and the button portion 141 , and drives the slider 1422 to slide in the buckle body 1421 , so as to provide the force required for the transmission member to separate from the buckle body 1421 .

[0109] For example, the driving part 14252 is a rod body with one end hinged to the sleeve 14251 and the other end hinged to the slider 1422. The hinged connection method is used to meet the angle change required for transmission. At the same time, the rod body can also transmit the force to the slider 1422 more quickly, and the pulling effect of the rod body can also satisfy the reciprocating sliding of the slider 1422 in the buckle body 1421.

[0110] For example, the driving portion 14252 can also be a wedge-shaped structure fixedly connected to the outer wall of the sleeve 14251, and the wedge-shaped structure and the slider 1422 are slidably matched through wedge-shaped grooves and wedge-shaped ribs. Similarly, when the wedge-shaped structure moves with the sleeve 14251, the wedge-shaped structure can push out or pull back the slider 1422 to make the slider 1422 slide back and forth in the buckle body 1421.

[0111] In this way, when the sleeve 14251 slides relative to the base 1424 along the pressing direction, the driving part 14252 transmits the force to the slider 1422, so that the slider slides in the buckle body 1421, meeting the requirement of separating the second transmission member 22.

[0112] Please refer to Figure 6 In some embodiments, the driving portion 14252 includes a connecting rod having one end hinged to the sleeve 14251 and the other end hinged to the slider 1422 .

[0113] It can be understood that the sleeve 14251, the connecting rod and the slider 1422 form a triangular structure. Optionally, the angle between the sliding direction of the sleeve 14251 and the axial direction of the connecting rod should be greater than the angle between the sliding direction of the slider 1422 and the axial direction of the connecting rod. In this way, the force transmission process is smoother.

[0114] Alternatively, please refer to Figure 8 The driving part 14252 includes a wedge block, which is connected to the outer wall of the sleeve 14251. The wedge block has a wedge surface, and the slider 1422 is slidably connected to the wedge surface.

[0115] It can be understood that when the wedge block moves with the sleeve 14251, its wedge surface interacts with the slider 1422 to push out or pull back the slider 1422, so that the slider 1422 can slide back and forth in the buckle body 1421. Specifically, a wedge groove can be provided on the wedge surface, and a wedge rib matching the wedge shape can be provided on the slider 1422, so as to meet the requirement of the slider 1422 sliding back and forth in the buckle body 1421.

[0116] Please refer to Figures 4 to 7 In some embodiments, the unlocking portion 142 further includes a reset member 1426 , which is sleeved on the base 1424 , with one end of the reset member 1426 abutting against the base 1424 and the other end abutting against the sleeve 14251 .

[0117] It can be understood that the reset member 1426 can be a spring, an elastic block, or a combination of a spring and an elastic block, which is used to restore the sleeve 14251 to its initial position and provide a corresponding pulling force for the slider 1422 to return to its initial position.

[0118] It should be noted that the direction of the restoring force of the reset member 1426 should be the same as the direction in which the sleeve 14251 slides relative to the base 1424 .

[0119] In this way, the reset member 1426 is used to reset the sleeve 14251 so that the sleeve 14251 is in the initial position, and also provides a corresponding pulling force for the slider 1422 to return to the initial position.

[0120] Please refer to Figure 4 and Figure 5 In some embodiments, along the pressing direction, a limiting groove 142c is provided on the sleeve 14251, and a limiting column 142d is provided on the base 1424, and the limiting column 142d is passed through the limiting groove 142c.

[0121] It can be understood that the extension direction of the limiting groove 142c should be the same as the sliding direction of the sleeve 14251 relative to the base 1424. At the same time, the two oppositely arranged groove inner walls of the limiting groove 142c are the sliding limit positions of the sleeve 14251 relative to the base 1424.

[0122] In this way, the limiting column 142d is inserted into the limiting groove 142c to limit the sliding distance of the sleeve 14251 relative to the base 1424 in the pressing direction.

[0123] Please refer to Figures 4 to 7 In some embodiments, the unlocking portion 142 further includes an anti-accidental touch structure 1427 , and the anti-accidental touch structure 1427 is used to limit the movement of the driving member 1425 relative to the base 1424 .

[0124] It can be understood that the unlocking part 142 separates the first transmission member 13 and the second transmission member 22 when the knob 12 fails to rotate. Therefore, under normal operation of medical personnel, the unlocking part 142 should be in a locked state. In order to maintain the locked state of the unlocking part 142, an anti-mistouch structure 1427 is added to limit the movement of the driving member 1425 relative to the base 1424.

[0125] For example, the anti-mistouch structure 1427 includes a convex portion arranged on the driving member 1425 and a concave portion arranged on the base 1424 or the buckle body 1421. The convex portion and the concave portion are adaptively connected to each other so that the driving member 1425 and the base 1424 remain temporarily relatively still. Once the force applied to the driving member 1425 is large enough to release the adaptive connection relationship between the convex portion and the concave portion, the driving member 1425 can move relative to the base 1424 again.

[0126] For example, the anti-mistouch structure 1427 includes a bracket structure mounted on the base 1424, which supports the driving member 1425. At the same time, when the driving member 1425 needs to move relative to the base 1424, the force applied to the driving member 1425 can be increased to destroy the bracket structure.

[0127] Thus, the anti-mistouch structure 1427 is used to reduce the probability of relative movement of the driving member 1425 relative to the base 1424 under abnormal operation, that is, to reduce the probability of separation of the second transmission member 22 and the first transmission member 13 under abnormal operation.

[0128] Specifically, please refer to Figure 5 and Figure 6 In some embodiments, the anti-accidental touch structure 1427 includes a protective tube mounted on the base 1424 , the protective tube includes a cylinder 14271 mounted on the base 1424 and a flange 14272 formed at one end of the cylinder 14271 , the flange 14272 is used to abut the driving member 1425 .

[0129] It can be understood that the protective tube is used to independently support the driving member 1425, specifically, the flange 14272 of the protective tube is used to independently support the driving member 1425, that is, the driving member 1425 can slide relative to the base 1424 only after breaking through the obstruction of the flange 14272. In addition, the thickness, width and angle of the flange 14272 relative to the cylinder 14271 can be adjusted according to the level of accidental touch prevention.

[0130] In some embodiments, there are multiple unlocking button assemblies 14, and each unlocking button assembly 14 is arranged on the operating body 11 with the central axis of the operating body 11 as the center. Each unlocking button assembly 14 is configured to unlock one or more second transmission members 22 of the insertion part 20, and each unlocking button assembly 14 can move synchronously or asynchronously relative to the operating body 11.

[0131] It can be understood that in order to realize multi-degree-of-freedom bending movement of the insertion part 20 in space, the number of second transmission members 22 can be multiple. Similarly, the number of first transmission members 13 corresponding to the number of second transmission members 22 is also multiple, then the number of unlocking button assemblies 14 can also be multiple.

[0132] In actual usage scenarios, each unlocking button assembly 14 may correspond to one or more second transmission members 22 of the insertion portion 20 , that is, one unlocking action of an unlocking button assembly 14 may complete the unlocking requirement of one or more second transmission members 22 .

[0133] At the same time, each unlocking button assembly 14 can be independently and movably connected to the operating body 11. For example, the current insertion part 20 has four second transmission members 22 to satisfy the bending freedom in four directions in space. Then, the corresponding second transmission members 22 can be unlocked by the corresponding four unlocking button assemblies 14, or the unlocking can be implemented by one unlocking button assembly 14.

[0134] In summary, according to the actual usage scenario, each unlock button assembly 14 can realize synchronous or asynchronous movement relative to the operating body 11. For example, in the scenario where each unlock button assembly 14 is operated synchronously, an annular screwing structure can be sleeved on the outer wall of the operating body 11, and the annular knob 12 structure can apply radial force to each unlock button assembly 14 while rotating around the central axis of the operating body 11, so that each unlock button assembly 14 is pressed synchronously.

[0135] In this way, the unlocking button assembly 14 can be configured with one or more second transmission members 22 of the unlocking insertion portion 20 according to actual use requirements. At the same time, each unlocking button assembly 14 can operate asynchronously independently, or operate synchronously and move relative to the operating body 11.

[0136] In some embodiments, there are multiple unlocking portions 142 , and each unlocking portion 142 is matched with the same button portion 141 .

[0137] It can be understood that when there are multiple second transmission members 22, the number of unlocking parts 142 can be increased in the same unlocking button assembly 14, that is, each unlocking part 142 corresponds to a second transmission member 22, that is, under the action of one pressing of the button part 141 of the unlocking button member, multiple unlocking parts 142 can be satisfied to unlock and separate the corresponding first transmission member 13 and the second transmission member 22.

[0138] In a second aspect, an embodiment of the present application further provides an endoscope system, including a display, a light source host, an image processing device and the above-mentioned endoscope 100.

[0139] It can be understood that the beneficial effects of the second aspect of the present application can refer to the beneficial effects stated in the first aspect, and will not be repeated here.

[0140] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
