[0001] The present disclosure relates to a holding system for an endoscope, and more particularly to a holding system for an endoscope that can adjust an imaging direction as needed and can hold the imaging direction as needed. [Background technology]

[0002] In conventional methods, a user, such as a medical professional, must hold an endoscope to control the imaging direction of the endoscope while operating the endoscope. With the above-described operation techniques, it is difficult for a user to accurately control other medical devices (e.g., other medical devices within the endoscope's sheath device) while observing an object with the endoscope. In light of this, it is desirable to provide an endoscope holding system that can adjust the imaging direction as needed and maintain the imaging direction as needed. Summary of the Invention

[0039] 1A and 1B, cross-sectional views of a holding system for an endoscope according to a specific embodiment of the present disclosure are shown. In the embodiment shown in FIGS. 1A and 1B, the holding system 100 includes a sleeve device 110, a first moving device 120, a second moving device 130, and a holding device 140. The first moving device 120 is connected to the sleeve device 110. The second moving device 130 is in contact with the first moving device 120. The holding device 140 is connected to the second moving device 130, allowing the first moving device 120 and the second moving device 130 to be in a relatively movable or held state. When the first moving device 120 and the second moving device 130 are in a relatively movable state, the first moving device 120 is movable relative to the second moving device 130. When the first mobile device 120 and the second mobile device 130 are in a held state, the first mobile device 120 and the second mobile device 130 hold each other, allowing the first mobile device 120 to not move relative to the second mobile device 130. Thus, a user, such as a medical professional, operates the holding device 140 to allow the first mobile device 120 and the second mobile device 130 to be in a relatively movable or held state.

[0040] In certain embodiments, the sleeve device 110 is connected to the first moving device 120, but the sleeve device 110 and the first moving device 120 hold each other. Thus, the sleeve device 110 can move together with the first moving device 120. Preferably, the first inner wall surface 122 of the first moving device 120 has a receiving groove 124, and the first connecting portion 115 of the sleeve device 110 is partially received in the receiving groove 124, allowing the sleeve device 110 and the first moving device 120 to hold each other. Preferably, the central axis of the sleeve device 110 (in other words, the central axis of the sleeve) is parallel to the central axis of the first moving device 120 (also known as the first central axis). In certain embodiments, the second moving device 130 defines a holding axis 131. The holding axis 131 is parallel to the central axis of the second moving device 130. Preferably, the holding axis direction 131 extends along the central axis of the second moving device 130. The central axis of the second moving device 130 is also known as the second central axis. The first moving device 120 defines a movement axis direction 121, which is parallel to the central axis of the first moving device 120. Preferably, the movement axis direction 121 extends along the central axis of the first moving device 120. A three-dimensional included angle 1010 is defined between the holding axis direction 131 and the movement axis direction 121. When the first moving device 120 and the second moving device 130 are in a relatively movable state, the first moving device 120 can move relative to the second moving device 130 to change the three-dimensional included angle 1010. Thus, a user can adjust the extension direction of the sleeve device 110 as needed. When the first moving device 120 and the second moving device 130 are in the holding state, the first moving device 120 and the second moving device 130 hold each other (while preventing the first moving device 120 from moving relative to the second moving device 130) and maintain the three-dimensional included angle 1010 at a specific three-dimensional angle. Therefore, the user can hold the extension direction of the sleeve device 110 in a specific direction as needed.

[0041] 1A and 1B , an internal thread 133 is disposed on the second inner wall surface 132 of the second moving device 130, and an external thread 143 is disposed on the third outer wall surface 142 of the holding device 140. The external thread 143 allows the holding device 140 to be connected to the internal thread 133 of the second moving device 130. A gap 1020 is defined between the first moving device 120 and the second moving device 130. A user can not only move the holding device 140 toward the gap 1020 relative to the second moving device 130 to meet their needs, but also bring the holding device 140 into contact with the first moving device 120 to allow the first moving device 120 and the second moving device 130 to be in a holding state. Alternatively, the user can not only move the holding device 140 relative to the second moving device 130 in a direction away from the gap 1020, i.e., in the exit direction, to meet his or her needs, but also separate the holding device 140 and the first moving device 120 from each other, allowing the first moving device 120 and the second moving device 130 to be in a relatively movable state.

[0042] In the embodiment shown in FIG. 1A , the holding device 140 faces away from the gap 1020, i.e., in an exit direction 1030, and moves relative to the second moving device 130, thereby separating the holding device 140 and the first moving device 120 from each other and allowing the first moving device 120 and the second moving device 130 to be in a relatively movable state. Preferably, in the relatively movable state, the holding device 140 and the first moving device 120 do not contact each other. In the embodiment shown in FIG. 1B , not only does the holding device 140 face into the gap 1020 (i.e., in an entry direction 1040) and move relative to the second moving device 130, but the holding device 140 also contacts the first moving device 120, allowing the first moving device 120 and the second moving device 130 to be in a held state. Preferably, in the holding state, the holding device 140 contacts the first moving device 120 and exerts pressure on the first moving device 120 to prevent the first moving device 120 from moving relative to the second moving device 130.

[0043] In certain embodiments, the retention system 100 further includes a closure device (not shown). The closure device is (e.g., detachably) connected to the sleeve device 110 and extends at least partially within the sleeve device 110. Preferably, the sleeve device 110 has a channel 111 therein that extends to a point between the first end 112 and the second end 114 of the sleeve device 110. The closure device must then remain within the channel 111 of the sleeve device 110 while the second end 114 is positioned inside the human body (e.g., inside the human skull during head surgery, or inside any part of the human body during any other surgery, although the application of the retention system 100 is not limited to surgery) to prevent injury to the human tissue that would otherwise be caused by the wall of the second end 114. Preferably, the free end of the closure device is opaque or a specific color. Therefore, during the process of placing the sleeve device 110 and the closure device within the human body (at this point, the free end of the closure device is positioned at the second end 114 of the sleeve device 110), the user can use a medical imaging system to observe and determine the position of the free end of the closure device within the human body.

[0044] In certain embodiments, the holding system 100 further includes an endoscopic device (not shown) connected (e.g., detachably connected) to the sleeve device 110 and extending at least partially within the sleeve device 110. Preferably, the sleeve device 110 has a channel 111 therein, which extends to a point between the first end 112 and the second end 114 of the sleeve device 110. Thus, a user can insert the endoscopic device (e.g., a medical endoscope) into the channel 111 once the second end 114 is positioned inside the human body (e.g., inside a human skull during head surgery, or any part of the human body during any other surgery, although application of the holding system 100 is not limited to surgery) to obtain an image of the internal environment of the human body. Preferably, the sleeve device 110 can be transparent or at least partially transparent (e.g., the second end 114 is transparent). Thus, the wall of the sleeve device 110 does not obstruct the view of the interior of the endoscopic device.

[0045] Preferably, the endoscopic device has a guide rail extending along its outer wall, and the sleeve inner wall 113 of the sleeve device 110 has a guide protrusion extending along at least one segment of the sleeve inner wall 113. When the endoscopic device is disposed within the channel 111 of the sleeve device 110, the guide protrusion is at least partially received within the guide rail of the endoscopic device. Thus, the guide rail of the endoscopic device and the guide protrusion of the sleeve device 110 guide the endoscopic device into the channel 111 during the process of disposing the endoscopic device within the channel 111. An endoscope disposed within the sleeve device 110 is disclosed in Taiwan Published Patent Application No. 111110998, entitled "Medical Endoscope System," the entire contents of which are incorporated herein by reference. The holding system of the present disclosure may also be applied to other types of endoscopes.

[0046] 2A and 2B, schematic diagrams of a first mover device 200 of a retention system in a specific embodiment of the present disclosure are shown. In the embodiment shown in FIGS. 2A and 2B, the first mover device 200 includes a first half 210 and a second half 220, and a first inner wall surface 230 of the first mover device 200 has a receiving groove 240. A sleeve device of the retention system is partially received within the receiving groove 240 to allow the first mover device 200 to be connected to the sleeve device and to hold the first mover device 200 and the sleeve device together. Preferably, the first half 210 is detachably connected to the second half 220 to form the first mover device 200. Therefore, when the first half 210 and the second half 220 are separated, the user places the sleeve device between the first half 210 and the second half 220, and then couples the first half 210 and the second half 220 together, allowing the sleeve device to be received in the receiving groove 240 of the first moving device 200. Thus, the user can connect or disconnect the first moving device 200 and the sleeve device as needed. In an alternative embodiment of the present disclosure, the first moving device is integrally formed. In another alternative embodiment of the present disclosure, the first moving device is made up of many more components.

[0047] Preferably, the first outer wall surface 250 of the first moving device 200 is convex, and the inner wall surface (also known as the second inner wall surface) of the second moving device is concave. The first outer wall surface 250 allows the first moving device 200 to contact the second inner wall surface of the second moving device. When the first moving device 200 and the second moving device are in a relatively movable state, the first outer wall surface 250 allows the first moving device 200 to move relative to the second inner wall surface of the second moving device.

[0048] In a particular embodiment, first half 210 has first engagement portions 216, 217, 218, and 219, and second half 220 has second engagement portions 226, 227, 228, and 229. First engagement portions 216, 217, 218, and 219 of first half 210 engage with second engagement portions 226, 227, 228, and 229 of second half 220, respectively, such that first half 210 and second half 220 form first mover device 200. Inner wall surface 213 of first half 210 has groove 214, and inner wall surface 223 of second half 220 has groove 224. Groove 214 and groove 224 form receiving groove 240 when first half 210 and second half 220 are engaged with each other. In a particular embodiment, the first engagement portions 216 , 217 , 218 , 219 are recesses disposed on the first half 210 and the second engagement portions 226 , 227 , 228 , 229 are protrusions disposed on the second half 220 .

[0049] Referring to FIG. 3A, a schematic diagram of a sleeve device 310 of a retention system in accordance with a specific embodiment of the present disclosure is shown. In the embodiment shown in FIG. 3A, the sleeve device 310 has a first connecting portion 315 and third connecting portions 316, 317. The first connecting portion 315 is disposed at a first end of the sleeve device 310, and the third connecting portions 316, 317 are disposed at the first connecting portion 315. The first connecting portion 315 of the sleeve device 310 is partially received in a receiving groove of a first moving device such that the first moving device is connected to the sleeve device 310. (Referring to FIG. 3B, the first connecting portion 315 of the sleeve device 310 is partially received in a receiving groove of a first moving device 320.)

[0050] The third connectors 316 and 317 enable the sleeve device 310 to be connected to the second connector of the endoscopic device. Preferably, the retention bump 318 is located on the top of the third connector 316, and the retention bump 319 is located on the top of the third connector 317. Preferably, the distance between the retention bumps 318 and 319 is less than the width of the middle of the second connector (see FIGS. 4A and 4B and their descriptions). FIG. 3A is merely an example and does not limit the third connector of the sleeve device, and FIGS. 4A and 4B do not limit the second connector of the endoscopic device. In a specific embodiment, the third connector of the sleeve device is a through-hole or recess located on the first connector, and the second connector of the endoscopic device is a protrusion located on the endoscopic device. When the endoscopic device is connected to the sleeve device, the second connector of the endoscopic device is received in the third connector of the sleeve device, and the endoscopic device is positioned at the correct point on the sleeve device. In another specific embodiment, the third connecting portion of the sleeve device is a protrusion disposed on the first connecting portion, and the second connecting portion of the endoscopic device is a recess disposed on the endoscopic device. When the endoscopic device is connected to the sleeve device, the third connecting portion of the sleeve device is received in the second connecting portion of the endoscopic device, and the endoscopic device is positioned at the correct point on the sleeve device.

[0051] In a specific embodiment, the sleeve device 310 has retaining portions 311 and 313 (also known as closure device retaining portions), which are disposed on the first connecting portion 315. The retaining portion 311 has a retaining bump 312, and the retaining portion 313 has a retaining bump 314. The closure device has a disk portion (see disk portion 561 in FIG. 5 ) which has a notch (see notch 562 in FIG. 5 ). As the closure device moves toward and connects to the sleeve device 310, the retention bumps 312 and 314 of the sleeve device 310 pass through the notch of the closure device, and the disk portion of the closure device is disposed between the first connecting portion 315 and the retention bumps 312 and 314. The closure device is then rotated so that the retention bumps 312 and 314 of the sleeve device 310 abut the disk portion of the closure device. Thus, the sleeve device 310 and the closure device hold each other.

[0052] 4A and 4B, schematic diagrams of an endoscopic device 450 of a retention system according to a specific embodiment of the present disclosure are shown. In the embodiment shown in FIGS. 4A and 4B, the endoscopic device 450 has a second connecting portion 451, a first front end 452, a second front end 453, and guide rails 454 and 455. The central segment of the second connecting portion 451 has a width (also known as a mid-section width). The upper segment of the second connecting portion 451 has a width (also known as an upper segment width). The lower segment of the second connecting portion 451 has a width (also known as a lower segment width). Preferably, the third connecting portion of the sleeve device has two retention bumps (arranged in the same manner as shown in FIG. 3A). The distance between the two retention bumps is less than the mid-section width of the second connecting portion 451. Preferably, the width of the upper segment gradually decreases upward. Therefore, when the second connecting portion 451 of the endoscope device 450 is connected to the third connecting portion of the sleeve device, the holding bump of the third connecting portion is held in the upper segment of the second connecting portion 451. Preferably, the width of the lower segment gradually decreases in the downward direction. Therefore, the second connecting portion 451 of the endoscope device 450 and the third connecting portion of the sleeve device can be easily connected.

[0053] In the embodiment shown in FIGS. 4A and 4B , one of the first front end 452 and the second front end 453 has an optical sensing unit, and the other has a liquid circulation unit. The optical sensing unit captures optical images. The liquid circulation unit guides a liquid (e.g., water) to the outside to rinse the target tissue or wash away foreign matter. The guide rails 454, 455 extend to the outer wall of the endoscopic device 450. When the endoscopic device 450 is placed in the channel of the sleeve device, the guide protrusions disposed in the channel are at least partially received in the guide rails 454, 455 of the endoscopic device 450, thereby positioning the endoscopic device 450 at the correct point within the channel.

[0054] Referring to Figure 5, a schematic diagram of a closure device 560 of a retention system in accordance with a specific embodiment of the present disclosure is shown. In the embodiment shown in Figure 5, the closure device 560 has a disk portion 561, a notch portion 562, and a closure portion 563. The disk portion 561 and the notch portion 562 serve to connect the closure device 560 to the closure device retainer of the sleeve device. The closure portion 563 closes the channel of the sleeve device during placement of the sleeve device within the human body. Preferably, the front end of the closure portion 563 is conical.

[0055] FIG. 6A is a schematic diagram of a second movement device of a support system according to a specific embodiment of the present disclosure. FIG. 6B is a partial cross-sectional view of a second movement device of a support system according to a specific embodiment of the present disclosure. In the embodiment shown in FIGS. 6A and 6B, second movement device 630 includes a body portion 634, a support portion 635, and a retaining portion 636. Body portion 634 is connected to support portion 635, and support portion 635 is connected to retaining portion 636. Body portion 634 has a second inner wall surface 632 and an internal thread portion 633. Internal thread portion 633 is disposed on second inner wall surface 632. Preferably, internal thread portion 633 is disposed on an upper segment of second inner wall surface 632. Preferably, second inner wall surface 632 is concave, while the first outer wall surface of the first movement device is convex. The first outer wall surface of the first mobile device can come into contact with the second inner wall surface 632 of the second mobile device 630. When the first mobile device and the second mobile device 630 are movable relative to each other, the first mobile device having the first outer wall surface can move relative to the second inner wall surface 632 of the second mobile device 630. Therefore, the user can adjust the three-dimensional angle between the movement axis direction of the first mobile device and the holding axis direction 631 of the second mobile device 630.

[0056] Preferably, the holder 636 of the second moving device 630 is held in place by an external device (the external device may be, for example, a robot arm, but the present disclosure is not limited thereto). For example, the holder 636 has a through-hole 637, by which the holder 636 is held in place and fixed to the external device. Preferably, the second inner wall surface 632 of the second moving device 630 has a second inner diameter (in other words, the second inner wall surface 632 defines a second inner diameter). The lower half of the second inner diameter gradually decreases from top to bottom to define a concave surface. Preferably, the upper half of the second inner diameter has a substantially equal width. Preferably, the bottom inner diameter 638 of the second moving device 630 is smaller than the outer diameter of the first moving device. Therefore, the first moving device is prevented from separating from the bottom of the second moving device 630.

[0057] Figure 7A is a schematic diagram of a retention device 740 of a retention system according to a specific embodiment of the present disclosure. Figure 7B is a cross-sectional view of a retention device 740 of a retention system according to a specific embodiment of the present disclosure. In the embodiment shown in Figures 7A and 7B, retention device 740 has a third outer wall surface 742, an external threaded portion 743, an inner wall surface 745, and a control portion 746. External threaded portion 743 is disposed on third outer wall surface 742. External threaded portion 743 allows retention device 740 to be connected to an internal threaded portion of a second movement device. The user can use the control unit 746 to adjust the degree to which the internal threads of the second moving device engage with the external threads 743 of the retaining device 740 to allow the retaining device 740 to move toward the second moving device (i.e., allow the retaining device 740 to move toward the gap between the first moving device and the second moving device) or away from the second moving device (i.e., allow the retaining device 740 to move away from the gap). Preferably, the inner wall surface 745 of the retaining device 740 has a first inner diameter (i.e., the inner wall surface 745 defines the first inner diameter). The lower half of the first inner diameter gradually decreases from bottom to top. Therefore, the retaining device 740 can easily enter the gap between the first moving device and the second moving device and easily come into contact with the first moving device.

[0058] 8A and 8B, schematic diagrams of the movement of a first moving device relative to a second moving device are shown. In the embodiment shown in FIGS. 8A and 8B, a sleeve device 810 is connected to a first moving device 820, which is in contact with a second moving device 830, with a gap 890 disposed between the first moving device 820 and the second moving device 830.
