Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an ultra-fine endoscope control device and an imaging system having the same. Background Technology

[0002] Ultra-thin endoscopes are primarily used in confined spaces. They consist of a handle, an insertion section connected to the handle, and an imaging mechanism housed within the handle. The insertion section employs an extremely fine diameter structure. The imaging mechanism includes a fiber optic bundle, an imaging sensor, and an imaging lens located between the imaging sensor and the fiber optic bundle. The front end of the fiber optic bundle extends to the end of the insertion section, while the rear end faces the imaging lens. Light signals carrying image information are transmitted from the front end to the rear end of the fiber optic bundle, and after passing through the imaging lens, are focused onto the imaging sensor for image formation. The imaging lens can typically be adjusted between the fiber optic bundle and the imaging sensor to ensure the clearest possible image.

[0003] In the prior art, the handle typically includes a mounting base with a mounting channel extending along a first direction. The image transmission fiber bundle, imaging lens, and imaging sensor are sequentially arranged within the mounting channel from front to back. A locking screw is provided on the mounting base at the position corresponding to the imaging lens, and the locking screw can be screwed into the mounting channel to press against the imaging lens.

[0004] With the above structure, it is difficult for operators to directly reach into the installation channel, so tools are needed to touch and move the imaging lens, which is cumbersome. After the imaging lens is adjusted into place, the locking screws need to be screwed into the installation channel to fix the imaging lens. During this process, in order to prevent the imaging lens from shifting, the operator needs to continuously use tools to keep the imaging lens in the adjusted position, which is difficult to operate with one hand and the adjustment operation is very inconvenient.

[0005] Therefore, it is necessary to improve the existing technology to overcome the aforementioned defects. Summary of the Invention

[0006] The purpose of this invention is to provide an ultra-fine endoscope control device and an imaging system having the same, which facilitates the adjustment of the imaging lens position.

[0007] The objective of this invention is achieved through the following technical solution: an ultra-thin endoscope control device, comprising:

[0008] The handle includes a mounting base, which has a through mounting channel along a first direction, and the outer wall of the mounting base is recessed inward and has a sliding hole that extends to the mounting channel;

[0009] A lens assembly includes a mounting member movably disposed within a mounting channel along the first direction and a lens mounted on the mounting member, the mounting member having a connecting portion extending from the sliding hole to the outside of the mounting base; and...

[0010] A locking member is threadedly connected to the protruding end of the connecting portion, the locking member being adapted to be screwed toward the mounting base to lock the mounting member, or screwed away from the mounting base to unlock the mounting member;

[0011] The sliding hole extends along the first direction, and the connecting part can move within the sliding hole along the first direction.

[0012] Furthermore, the locking element includes:

[0013] The knob is located outside the sliding hole;

[0014] The first threaded component is located on the side of the knob portion facing the connecting portion.

[0015] The first threaded component is threadedly connected to the connecting part.

[0016] Furthermore, in the opening direction of the sliding hole, the projection of the knob portion is at least partially located outside the sliding hole.

[0017] Furthermore, the connecting portion includes:

[0018] The connecting part body is slidably connected to the sliding hole;

[0019] The second threaded component is disposed on the side of the connecting part body facing the locking component and is threadedly connected to the first threaded component;

[0020] The side of the connecting part body facing the locking member does not protrude relative to the sliding hole.

[0021] Furthermore, one of the first threaded component and the second threaded component is a threaded hole, and the other is a stud.

[0022] Furthermore, the outer wall of the mounting base is recessed inward to form a receiving groove, the locking member is received in the receiving groove, and the sliding hole is recessed inward from the bottom of the receiving groove.

[0023] Furthermore, the ultra-fine endoscope also includes an anti-disengagement structure disposed on the locking member. The anti-disengagement structure has a first state of abutting against the side wall of the receiving groove and a second state of releasing the abutment. When in the first state, the anti-disengagement structure restricts the locking member from rotating relative to the connecting part. When in the second state, the locking member can rotate relative to the connecting part.

[0024] Furthermore, the anti-detachment structure includes:

[0025] The transmission component is threadedly connected to the locking component;

[0026] At least two abutting members are disposed opposite to the locking member, and the abutting members can be moved relative to the locking member to either the first state or the second state;

[0027] The abutment member switches from the second state to the first state in response to the tightening of the transmission member.

[0028] Furthermore, the rotation direction of the transmission member is consistent with the rotation direction of the locking member, and the abutment member is movably disposed on the locking member along a direction perpendicular to the rotation axis of the transmission member, with the transmission member and the abutment member having inclined surface engagement.

[0029] Furthermore, the anti-detachment structure includes an elastic member connected to the abutment member, the elastic member being adapted to provide a force that drives the abutment member from the first state to the second state.

[0030] Furthermore, the present invention also provides an endoscopic imaging system, comprising:

[0031] The aforementioned ultra-thin endoscope control device is used for image acquisition;

[0032] An image data processing device, communicatively connected to the ultra-fine endoscope control device, is used to process the acquired images; and,

[0033] The display device is communicatively connected to the image data processing device to display the processed image.

[0034] Compared with the prior art, the present invention has the following advantages: By providing a sliding hole on the mounting base that communicates with the mounting channel, the mounting part can extend out of the mounting base through the sliding hole, thereby facilitating the operator to slide the mounting part directly outside the mounting base; in addition, a locking element is threadedly connected to the connecting part of the mounting part extending out of the mounting base, and the operator can move the mounting part by turning the locking element, and the locking element can be rotated toward the mounting base to lock the mounting part, or rotated away from the mounting base to unlock the mounting part. The locking and unlocking operations are very convenient and suitable for one-handed operation, effectively improving the adjustment efficiency. Attached Figure Description

Detailed Implementation

[0045] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this application. Furthermore, it should be noted that, for ease of description, only the parts relevant to this application are shown in the accompanying drawings, not the entire structure. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0046] The terms “comprising” and “having”, and any variations thereof, used in this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or apparatus.

[0047] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0048] Please see Figures 1 to 3 As shown, a preferred embodiment of the ultra-fine endoscope control device of the present invention includes: a handle 100, including a mounting base 110, having a mounting channel 111 extending through it in a first direction, and a sliding hole 112 extending through the mounting channel 111 on the outer wall of the mounting base 110; a lens assembly 200, including a mounting member 210 movably disposed in the mounting channel 111 in the first direction and a lens 220 mounted on the mounting member 210, the mounting member 210 having a connecting portion 211 extending from the sliding hole 112 to the outside of the mounting base 110; and a locking member 300, threadedly connected to the protruding end of the connecting portion 211, the locking member 300 being adapted to be screwed toward the mounting base 110 to lock the mounting member 210, or screwed away from the mounting base 110 to unlock the mounting member 210; wherein the sliding hole 112 extends along the first direction, and the connecting portion 211 is movable within the sliding hole 112 along the first direction.

[0049] This invention provides a sliding hole 112 on the mounting base 110 that communicates with the mounting channel 111, allowing the mounting component 210 to extend out of the mounting base 110 via the sliding hole 112. This facilitates direct sliding of the mounting component 210 outside the mounting base 110 by the operator. Furthermore, a locking component 300 is threaded onto the connecting portion 211 of the mounting component 210 extending out of the mounting base 110. The operator can move the mounting component 210 by moving the locking component 300, and the locking component 300 can be rotated toward the mounting base 110 to lock the mounting component 210, or rotated away from the mounting base 110 to unlock the mounting component 210. The locking and unlocking operations are very convenient and suitable for one-handed operation, effectively improving adjustment efficiency.

[0050] Furthermore, the outer wall of the mounting base 110 is recessed inwardly with a receiving groove 113, and the locking member 300 is received in the receiving groove 113, thereby preventing the locking member 300 from protruding relative to the mounting base 110, and facilitating the subsequent insertion of the handle 100 into the mounting base 110. The sliding hole 112 is formed by protruding inwardly from the bottom of the receiving groove 113, and the locking member 300 is adapted to abut against the bottom of the receiving groove 113 to restrict the movement of the mounting member 210.

[0051] Furthermore, the rotation axis of the locking member 300 is perpendicular to the first direction and coincides with the recessed direction of the receiving groove 113 and / or the sliding hole 112, so as to facilitate the operator's tightening. The locking member 300 includes a knob portion 310 and a first threaded member 320. The knob portion 310 is located outside the sliding hole 112, and the first threaded member 320 is disposed on the side of the knob portion 310 facing the connecting portion 211 and is adapted to be threadedly connected to the connecting portion 211. In the opening direction of the sliding hole 112, the projection of the knob portion 310 is at least partially located outside the sliding hole 112, thereby ensuring that the knob portion 310 can reliably abut against the bottom of the receiving groove 113. Preferably, an anti-slip structure can be provided between the bottom of the receiving groove 113 and the knob portion 310, which can increase the friction in the first direction when the knob portion 310 abuts against the bottom of the groove, effectively preventing the knob portion 310 from shifting. The anti-slip structure can specifically be an anti-slip texture provided on the bottom of the groove and / or on the side of the knob 310 facing the bottom of the groove.

[0052] Furthermore, the connecting portion 211 includes a connecting portion body 2111 and a second threaded member 2112. The connecting portion body 2111 is slidably connected to the sliding hole 112 to guide the mounting member 210 to move only along the first direction. The second threaded member 2112 is disposed on the side of the connecting portion body 2111 facing the locking member 300 and is threadedly connected to the first threaded member 320. Preferably, the side of the connecting portion body 2111 facing the locking member 300 does not protrude relative to the sliding hole 112, thereby avoiding restricting the knob portion 310 from abutting against the outer wall of the mounting base 110. One of the first threaded member 320 and the second threaded member 2112 is a threaded hole, and the other is a stud.

[0053] Furthermore, after prolonged use, the locking element 300 may loosen. To avoid this, as a preferred embodiment, refer to... Figures 4 to 6 As shown, the ultra-fine endoscope control device also includes an anti-disengagement structure 400 disposed on the locking member 300. The anti-disengagement structure 400 has a first state abutting against the side wall of the receiving groove 113 and a second state of releasing the abutment. When in the first state, the anti-disengagement structure 400 restricts the locking member 300 from rotating relative to the connecting part 211. When in the second state, the locking member 300 can rotate relative to the connecting part 211.

[0054] The anti-detachment structure 400 includes a transmission member 410 and at least two abutment members 420. The transmission member 410 is threadedly connected to the locking member 300. The abutment members 420 are disposed opposite to the locking member 300. The abutment members 420 can move relative to the locking member 300 to the first state or the second state. The abutment members 420 switch from the second state to the first state in response to the tightening of the transmission member 410.

[0055] Preferably, in this embodiment, in order to ensure that the abutment 420 and the receiving groove 113 reliably abut against each other, the receiving groove 113 has two opposing first abutment surfaces 1131. The first abutment surfaces 1131 extend along the first direction to both sides of the sliding hole 112. The first abutment surfaces 1131 are parallel to the first direction. When the locking member 300 is in the tightened state, the two abutment members 420 are respectively facing different first abutment surfaces 1131.

[0056] Furthermore, the rotation direction of the transmission member 410 is consistent with the rotation direction of the locking member 300, thereby facilitating the turning of the transmission member 410 and preventing the locking member 300 from loosening during the turning of the transmission member 410. The abutment member 420 is movably disposed on the locking member 300 along a direction perpendicular to the rotation axis of the transmission member 410. The transmission member 410 and the abutment member 420 engage with each other on an inclined surface, thereby converting the force exerted by the transmission member 410 in the direction of its rotation axis into the force exerted by the abutment member 420 in the direction perpendicular to the rotation axis of the transmission member 410.

[0057] Specifically, the transmission component 410 includes a tapered portion 411 and a screw portion 412. The tapered portion 411 has a first end and a second end. The first end has an inwardly recessed slot for engaging with an external tool to achieve rotation of the transmission component 410. The cross-section of the tapered portion 411 gradually decreases from the first end to the second end, and the screw portion 412 is located at the second end. (Refer to...) Figure 7 and Figure 8 As shown, the abutment 420 is a rod-shaped structure, which includes a rod body 421 and a wedge block 422 fixed to one end of the rod body 421. The other end of the rod body 421 faces the side wall of the receiving groove 113, and the wedge block 422 engages with the inclined surface of the cone portion 411.

[0058] The knob portion 310 has a recessed cavity 311 on its end face away from the mounting member 210 to accommodate the anti-detachment structure 400. The cavity 311 includes a first accommodating portion 3111 for accommodating the transmission member 410 and a second accommodating portion 3112 for accommodating the supporting member 420. A connecting hole 312 is provided at the bottom of the first accommodating portion 3111, and the screw portion 412 is threadedly connected to the connecting hole 312.

[0059] In the direction of the rotation axis of the vertical transmission member 410, the second receiving portion 3112 has a through structure, so that one end of the abutment member 420 extends out of the knob portion 310 and the other end extends into the first receiving portion 3111.

[0060] Preferably, the bottom height of the second receiving portion 3112 is higher than the bottom height of the first receiving portion 3111, such that a second abutting surface 3113 is formed at the connection between the first receiving portion 3111 and the second receiving portion 3112. The wedge-shaped block 422 protrudes relative to the outer periphery of the rod 421 and faces the second abutting surface 3113 to prevent the abutting member 420 from disengaging from the second receiving portion 3112 in a direction perpendicular to the rotation axis of the transmission member 410. When the transmission member 410 is tightened, it can push the wedge-shaped block 422 toward the second abutting surface 3113 and abut against it, so that the abutting member 420 is in a first state.

[0061] Preferably, an elastic element (not shown) may be provided between the abutment 420 and the wedge block 422. The elastic element is specifically a spring, which is adapted to provide a force to drive the abutment 420 from a first state to a second state, so as to reliably press the wedge block 422 against the cone 411, such that the abutment 420 moves to the first state in response to the tightening of the transmission member 410, and moves to the second state in response to the loosening of the transmission member 410.

[0062] Furthermore, in order to further improve the reliability of locking the mounting component 210, the outer wall of the mounting base 110 is recessed inward and provided with a limiting hole 114 that extends to the mounting channel 111. The limiting hole 114 is internally threaded to a limiting component (not shown) that abuts against the mounting component 210. Preferably, there are multiple limiting holes 114, which are distributed at intervals along the periphery of the mounting component 210.

[0063] Furthermore, referring to Figure 1 and Figure 2 As shown, the mounting component 210 includes a sleeve portion 212 adapted to the inner contour of the mounting channel 111. In a first direction, the sleeve portion 212 has a through structure, and the lens 220 is fixed inside the sleeve portion 212. The ultra-fine endoscope control device also includes an image transmission fiber bundle 500 and an imaging sensor 600 fixed inside the mounting channel 111. The image transmission fiber bundle 500 is located at the front end of the lens assembly 200, and the imaging sensor 600 is located at the rear end of the lens assembly 200.

[0064] Furthermore, the handle 100 includes a housing 120, the inner contour of which is adapted to the outer contour of the mounting base 110, and the housing 120 is fixedly sleeved on the outside of the mounting base 110. In addition, the ultra-fine endoscope control device also includes an insertion portion 700 fixed to the front end of the handle 100, and one end of the image transmission fiber bundle 500 away from the lens 220 extends into the insertion portion 700.

[0065] In addition, the present invention also provides an endoscopic imaging system, including the aforementioned ultra-thin endoscope control device, image data processing device (not shown), and display device (not shown). The ultra-thin endoscope control device is used to acquire images. The image data processing device is communicatively connected to the ultra-thin endoscope control device and is used to process the acquired images. The display device is communicatively connected to the image data processing device to display the processed images, thereby facilitating observation by the operator.

[0066] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
