Description

[0001] This invention relates to the field of medical device technology, and in particular to a master operator suitable for controlling the movement of an endoscope in the natural cavities of the human body. Background Technology

[0002] In recent years, minimally invasive surgery has undergone a tremendous leap from multi-port surgery to single-port surgery, and then to surgery through natural orifices.

[0003] Existing endoscopes include an insertion section, an operating handle, and a control device. The insertion section is cable-like, with a camera unit installed at its end. The insertion section is used to insert into the body through natural body cavities. The operating handle is located at the end of the insertion section furthest from the camera unit. The control device collects the movement information of the operating handle to control the movement of the endoscope within the body cavity. During endoscopic examinations or minimally invasive surgeries in a supine position, because the patient lies supine on the operating table, the operator must adjust their posture according to the scenario to ensure the insertion section reaches the body cavity. This results in limited operating space, restricted operation, and the need to maintain a specific posture for extended periods, leading to significant physical strain and poor comfort during use.

[0104] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0105] The present invention is described herein with respect to structural embodiments and methods. It should be understood that this is not intended to limit the invention to the specific disclosed embodiments; the invention can be practiced using other features, elements, methods, and embodiments. Similar elements in different embodiments are typically designated with similar numbers.

[0106] Existing endoscopes consist of an insertion section and an operating handle. The insertion section is cable-like, with a camera unit installed at its end. The insertion section is used to insert into the body through natural cavities. The operating handle is located at the end of the insertion section furthest from the camera unit. When using endoscopes for supine examinations or minimally invasive surgeries, such as gynecological, uterine, or urological procedures, the patient must lie supine on the operating table, and the surgeon must sit to one side. The operator must adjust their own posture according to the patient to insert the insertion section into the body's natural cavity. This results in limited operating space, restricted operation, and the need to maintain a specific posture for extended periods, leading to significant physical strain and poor comfort during use.

[0107] Figure 1 This is a perspective view of a first embodiment of the main operator according to an embodiment of the present invention; Figure 2 This is a partial view of the main operator's highlighted slide rail according to an embodiment of the present invention; Figure 3 This is a partial view of the main operator's sleeve, as shown in an embodiment of the present invention.

[0108] This invention provides a master operator suitable for controlling the movement of an endoscope in a human body's natural cavities, comprising a support frame 1, a control device, a feeding mechanism 2, and a control mechanism 3. The support frame 1 extends in a first direction, which is vertical. The control device is configured to control the movement of the endoscope 8 in the human body's natural cavities. The feeding mechanism 2 is mounted on the support frame 1 and is configured to move in a second direction perpendicular to the first direction, thereby enabling the control device to control the endoscope 8 to move along the second mapping direction. The control mechanism 3 is mounted at the end of the feeding mechanism 2 away from the support frame 1 and includes a first control mechanism 31, a second control mechanism 32, and a third control mechanism 33. The first control mechanism 31 is configured to rotate about a first axis extending along a first direction, thereby causing the control device to control the endoscope 8 to rotate about a first mapping axis extending along a first mapping direction; the second control mechanism 32 is configured to rotate about a second axis extending along a second direction, thereby causing the control device to control the endoscope 8 to rotate about a second mapping axis extending along a second mapping direction perpendicular to the first mapping direction; the third control mechanism 33 is configured to rotate about a third axis extending along a third direction perpendicular to the first and second directions, thereby causing the control device to control the endoscope 8 to rotate about a third mapping axis extending along a third mapping direction perpendicular to the first and second mapping directions.

[0109] According to the main operator in the above embodiments, refer to Figure 1 During use, the operator operates the feeding mechanism 2 and the control mechanism 3. When operating the feeding mechanism 2, the operator can move the feeding mechanism 2 along the second direction, so that the control device can control the endoscope 8 to move along the second mapping direction. When operating the control mechanism 3, the operator can drive the first control mechanism 31 to rotate around the first axis extending along the first direction, drive the second control mechanism 32 to rotate around the second axis extending along the second direction, and drive the third control mechanism 33 to rotate around the third axis extending along the third direction. This allows the control device to control the endoscope 8 to rotate around the first mapping axis, the second mapping axis, and the third mapping axis, thus achieving the purpose of controlling the main operator to indirectly control the movement of the endoscope 8 in the body's natural cavities. The operator is freed from the limitations of the usage scenario and position when using the endoscope 8. The operator does not have to maintain a specific posture for a long time, which improves the convenience of using the endoscope and enhances the comfort of operation.

[0110] In one exemplary embodiment, reference is made to Figure 2 and 3The support frame 1 extends in a first direction, i.e., the support frame 1 is vertically arranged. An adjustment assembly 6 is provided on the support frame 1, which includes a slide rail 61, a sleeve 62, and a locking element 63. The slide rail 61 is mounted on the top of the support frame 1 and is vertically arranged; the sleeve 62 is fitted onto the top of the support frame 1 and is vertically slidably mounted on the slide rail 61; the feed mechanism 2 is mounted on the sleeve 62; the locking element 63 is mounted on the sleeve 62 and is used to prevent the sleeve 62 from sliding relative to the slide rail 61.

[0111] Specifically, at least one slide rail 61 is provided; in this embodiment, four slide rails 61 are provided, which surround the top of the support frame 1 and are spaced apart to improve the balance of the support frame 1. A sleeve 62 is fitted onto the support frame 1, and an adapter block is installed on each sleeve 62 opposite to the slide rail 61. The adapter block slides and engages with the slide rail 61 to guide the vertical movement of the sleeve 62. A locking element 63 is installed on the adapter block; the locking element 63 is a clamp or locking screw, etc., and is used to prevent the sleeve 62 from sliding relative to the slide rail 61. It positions the sleeve 62 and the feeding mechanism 2 and control mechanism 3 installed on the sleeve 62 in the vertical direction, thereby adjusting the height of the sleeve 62. This is suitable for minimally invasive surgery on different patients, improving its applicability.

[0112] In one exemplary embodiment, reference is made to Figure 2 Thrust rings 611 are installed at both ends of the slide rail 61 to prevent the sleeve 62 from slipping off the slide rail 61 and to improve the safety when adjusting the height of the sleeve 62.

[0113] In one exemplary embodiment, reference is made to Figure 2 The mounting bracket 311 is equipped with a push-up assembly 7, which can extend and retract vertically. The push-up assembly 7 is a metal spring or a gravity-balanced gas spring, etc. The push-up assembly 7 contacts the sleeve 62 and is used to lift the sleeve 62 upward. When the operator moves the sleeve 62 upward, the weight of the sleeve 62 is relatively large. The push-up assembly 7 can lift the sleeve 62 upward, sharing the force exerted by the operator when moving the sleeve 62, thus improving the ease of use.

[0114] In one exemplary embodiment, the bottom of the support frame 1 is equipped with casters, which facilitates the operator to move the position of the main operator as needed.

[0115] Figure 4 This is a partial view highlighting the feed mechanism of the main operator according to an embodiment of the present invention;

[0116] Figure 5 This is a partially enlarged schematic diagram of the prominent constraint component of the master operator according to an embodiment of the present invention.

[0117] In one exemplary embodiment, reference is made to Figure 4The feeding mechanism 2 includes a linkage mechanism 21 and a first detection mechanism 22. The first end of the linkage mechanism 21 is mounted on the sleeve 62, and the second end of the linkage mechanism 21 extends along a second direction. The first detection mechanism 22 is adapted to detect the movement distance of the second end of the linkage mechanism 21 relative to the first end in the second direction. The control device controls the movement of the endoscope 8 along the second mapping direction based on the movement distance.

[0118] In one exemplary embodiment, reference is made to Figure 4 The linkage mechanism 21 includes a first slave link 211, a second slave link 212, a first main link 213, a second main link 214, a first mounting portion 215, a second mounting portion 216, and a third mounting portion 217. The first mounting portion 215 is mounted on the sleeve 62; the first slave link 211 and the second slave link 212 are rotatably mounted on the first mounting portion 215 via two pivots 218, both of which are vertically arranged; the second mounting portion 216 is rotatably mounted on the end of the first slave link 211 and the second slave link 212 away from the first mounting portion 215 about an axis in a first direction; the first main link 213 and the second main link 214 are both rotatably mounted on the second mounting portion 216 about an axis in a first direction; the third mounting portion 217 is rotatably mounted on the end of the first main link 213 and the second main link 214 away from the second mounting portion 216 about an axis in a first direction.

[0119] In one exemplary embodiment, reference is made to Figure 4 A limit block 2151 is installed on the first mounting part 215, which is suitable for restricting the first connecting rod 211 and the second connecting rod 212 from rotating on one side in the second direction toward or away from the first mounting part 215.

[0120] In one exemplary embodiment, reference is made to Figure 5 The linkage mechanism 21 also includes a constraint component 219, which is mounted on the second mounting portion 216 and is adapted to restrict the first main link 213 and the second main link 214 from rotating in opposite directions with the first secondary link 211 and the second secondary link 212 relative to the second mounting portion 216 at the same angular velocity, so that the third mounting portion 217 reciprocates relative to the first mounting portion 215 along the second direction.

[0121] Specifically, refer to Figure 5The constraint assembly 219 includes a connecting shaft 2191, a driving gear 2192, and a driven gear 2193. The connecting shaft 2191 is rotatably mounted on the second mounting portion 216 about an axis in a first direction and extends along the first direction. One end of the connecting shaft 2191 is fixed relative to the first main connecting rod 213, and the connecting shaft 2191 rotates relative to the first driven connecting rod 211. The driving gear 2192 is mounted on the connecting shaft 2191 and is fixed relative to the connecting shaft 2191. The driven gear 2193 is rotatably mounted on the second mounting portion 216 and meshes with the driving gear 2192. The driven gear 2193 is fixed relative to the second driven connecting rod 212.

[0122] According to the above embodiment, when the main operator pushes the third mounting part 217 towards the sleeve 62, the first main connecting rod 213 and the second main connecting rod 214 rotate towards the first slave connecting rod 211 and the second slave connecting rod 212. At the same time, the connecting shaft 2191 and the driving gear 2192 rotate with the rotation of the first main connecting rod 213, thereby the driven gear 2193 rotates with the rotation of the driving gear 2192, which in turn drives the second slave connecting rod 212 and the first slave connecting rod 211 towards the first main connecting rod. 213 and the second main link 214 rotate in the same direction. The constraint assembly 219 restricts the first main link 213 and the second main link 214 from rotating in opposite directions relative to the first slave link 211 and the second slave link 212 with the same angular velocity. The third mounting part 217 moves toward the first mounting part 215 and decreases the distance between the third mounting part 217 and the first mounting part 215. Conversely, it increases the distance between the third mounting part 217 and the first mounting part 215.

[0123] In one exemplary embodiment, reference is made to Figure 4 The first detection mechanism 22 includes a first linkage gear 221 and a first angle sensor 222. The first linkage gear 221 is mounted on a pivot 218 of the second driven link 212 to rotate with the second driven link 212; the first angle sensor 222 meshes with the first linkage gear 221 to detect the movement distance of the third mounting part 217 relative to the first mounting part 215 in a second direction based on the rotation angle of the first linkage gear 221.

[0124] In one exemplary embodiment, reference is made to Figure 4 The feed mechanism 2 also includes a first braking mechanism 23, which is an electromagnetic brake 41, installed on the first mounting part 215 and meshing with the first linkage gear 221, and is used to prevent the second connecting rod 212 from rotating relative to the first mounting part 215.

[0125] In one exemplary embodiment, the control device includes a host computer and a main control unit, adapted to receive rotation angle information of the first linkage gear 221 transmitted from the first angle sensor 222, so as to obtain the movement distance of the third mounting part 217 relative to the first mounting part 215 in a second direction and control the movement distance of the endoscope 8 in the human body natural cavity along the second mapping direction.

[0126] According to the main operator of the above embodiment, as the first main link 213 and the second main link 214 rotate toward or away from the first secondary link 211 and the second secondary link 212, the distance between the third mounting part 217 and the first mounting part 215 increases or decreases. The first linkage gear 221 rotates with the second secondary link 212. At the same time, the first angle sensor 222 meshes with the first linkage gear 221 and rotates. The first angle sensor 222 obtains the rotation angle of the first linkage gear 221 and detects the moving distance of the third mounting part 217 relative to the first mounting part 215 in the second direction, so that the control device controls the moving distance of the endoscope 8 along the second mapping direction according to the moving distance.

[0127] When the third mounting part 217 moves to the desired position, the first braking mechanism 23 prevents the second connecting rod 212 from rotating relative to the first mounting part 215, thereby positioning the feed mechanism 2, maintaining the position of the feed mechanism 2, and relieving the operator of the need to maintain the state of the feed mechanism 2.

[0129] In one exemplary embodiment, reference is made to Figure 6 The first control mechanism 31 includes a mounting bracket 311, a first connecting portion 312, and a second detection mechanism 313. The mounting bracket 311 is mounted on the end of the feeding mechanism 2 away from the sleeve 62; the first connecting portion 312 is rotatably connected to the mounting bracket 311 via a first rotating shaft 3121 extending in a first direction; the second detection mechanism 313 is adapted to detect a first rotation angle of the first connecting portion 312 about the first rotating shaft 3121, and the control device controls the endoscope 8 to rotate about a first mapping axis extending in a first mapping direction based on the first rotation angle.

[0130] Specifically, refer to Figure 6 and 7The second detection mechanism 313 includes a second linkage gear 3131 and a second angle sensor 3132. The second linkage gear 3131 is mounted on the first rotating shaft 3121 to rotate with the first rotating shaft 3121; the second angle sensor 3132 meshes with the second linkage gear 3131 to detect the first rotation angle of the first connecting part 312 around the first rotating shaft 3121 based on the rotation angle of the second linkage gear 3131.

[0131] According to the main operator of the above embodiment, when the operator drives the first connecting part 312 to rotate around the first rotating shaft 3121, the second linkage gear 3131 rotates with the first rotating shaft 3121. The second angle sensor 3132 meshes with the second linkage gear 3131 and rotates, thereby detecting the first rotation angle of the first connecting part 312 around the first rotating shaft 3121 based on the rotation angle of the second linkage gear 3131, and then causing the control device to control the endoscope 8 to rotate around the first mapping axis extending in the first mapping direction based on the first rotation angle.

[0132] In one exemplary embodiment, reference is made to Figure 6 The first control mechanism 31 further includes a second braking mechanism 4, mounted on the mounting bracket 311, adapted to prevent the first connecting portion 312 from rotating relative to the mounting bracket 311. The second braking mechanism 4 includes a brake 41, a transmission wire 42, and a drive assembly 43. The brake 41 is slidably mounted on the mounting bracket 311 and is an electromagnetic brake 41; the transmission wire 42 is wound between the brake 41 and the first rotating shaft 3121, adapted to stop rotation under the control of the brake 41 to prevent the first connecting portion 312 from rotating relative to the mounting bracket 311; the drive assembly 43 is mounted on the mounting bracket 311 and adapted to drive the brake 41 to move toward or away from the first rotating shaft 3121.

[0133] According to the main operator of the above embodiment, when the second braking mechanism 4 is used, the brake 41 prevents the transmission wire 42 from rotating, and the drive assembly 43 moves the brake 41 away from the first rotating shaft 3121, thereby increasing the distance between the brake 41 and the first rotating shaft 3121, tensioning the transmission wire 42, and thus preventing the first rotating shaft 3121 from rotating relative to the mounting bracket 311, thereby positioning the first connecting part 312 and freeing the operator from maintaining the position of the first connecting part 312.

[0134] In one exemplary embodiment, reference is made to Figure 8The mounting bracket 311 is equipped with a fixed plate 3111 and a sliding plate 3112.

The two sliding blocks 432 respectively abut against the two inclined end faces of the sliding frame 431 and are slidably mounted on the mounting frame 311. The two lead screws 433 extend along the third direction, pass through the two sliding blocks 432 respectively, and are threadedly connected to the sliding blocks 432. Under the rotation drive of the lead screws 433, the two sliders slide along the lead screws 433, and the sliders slide relative to the two inclined end faces of the sliding frame 431, thereby driving the sliding frame 431 to slide along the second direction.

[0135] In one exemplary embodiment, reference is made to Figure 8 An operating component 5 is provided on the mounting frame 311. The operating component 5 includes two driven wheels 51, an operating wheel 52, and a conveyor belt 53. The two driven wheels 51 are rotatably mounted on the mounting frame 311 and are coaxially connected to two lead screws 433 respectively. The operating wheel 52 is rotatably mounted on the mounting frame 311. The conveyor belt 53 is wound around the operating wheel 52 and the two driven wheels 51 so as to drive the two driven wheels 51 to rotate under the rotation drive of the operating wheel 52.

[0136] According to the main operator of the above embodiment, when the brake 41 moves toward or away from the first rotation direction, the operator rotates the operating wheel 52, thereby driving the conveyor belt 53 and the two driven wheels 51 to rotate, which in turn drives the two lead screws 433 to rotate. The two sliding blocks 432 move along the lead screws 433 in the third direction under the drive of the two lead screws 433. The two sliding blocks 432 slide relative to the two end faces of the sliding frame 431 that are inclined, and drive the sliding frame 431 to move in the second direction. The brake 41 and the sliding plate 3112 move with the sliding frame 431, thus achieving the purpose of moving the brake 41 toward or away from the first rotation direction.

[0139] According to the main operator in the above embodiment, the operator controls the second connecting part 321 to rotate around the second rotating shaft 3211. The third linkage gear 3221 rotates with the second rotating shaft 3211. The third angle sensor 3222 meshes with the third linkage gear 3221 and rotates. Based on the rotation angle of the third linkage gear 3221, the second rotation angle of the second connecting part 321 around the second rotating shaft 3211 is detected, so that the control device controls the endoscope 8 to rotate around the second mapping axis extending in the second mapping direction based on the second rotation angle.

[0140] In one exemplary embodiment, reference is made to Figure 6 The second control mechanism 32 also includes a third braking mechanism 323. The third brake 41 is an electromagnetic brake 41, which is installed on the first connecting part 312 and meshes with the third linkage gear 3221, and is suitable for preventing the second connecting part 321 from rotating relative to the first connecting part 312.

[0141] According to the master operator in the above embodiment, when the first connecting part 312 is rotated to the desired position, the third braking mechanism 323 locks the third linkage gear 3221, thereby freeing the operator from maintaining the state of the first connecting part 312.

In this embodiment, the first rotation axis 3121, the second rotation axis 3211, and the third rotation axis 3311 intersect. The fourth detection mechanism 332 is adapted to detect the third rotation angle of the handheld part 331 around the third rotation axis 3311. The control device controls the endoscope 8 to rotate around the third mapping axis extending in the third mapping direction based on the third rotation angle.

[0143] Specifically, refer to Figure 6 The fourth detection mechanism 332 includes a fourth linkage gear 3321 and a fourth angle sensor 3322. The fourth linkage gear 3321 is mounted on the third rotation shaft 3311 to rotate with the third rotation shaft 3311; the fourth angle sensor 3322 meshes with the fourth linkage gear 3321 to detect the third rotation angle of the handheld part 331 around the third rotation shaft 3311 based on the rotation angle of the fourth linkage gear 3321.

[0144] According to the main operator of the above embodiment, when the operator controls the handheld part 331 to rotate around the third rotation axis 3311, the fourth linkage gear 3321 rotates with the third rotation axis 3311, and the fourth angle sensor 3322 meshes with the fourth linkage gear 3321 and rotates, so as to detect the third rotation angle of the handheld part 331 around the third rotation axis 3311 based on the rotation angle of the fourth linkage gear 3321, so that the control device controls the endoscope 8 to rotate around the third mapping axis extending in the third mapping direction based on the third rotation angle.

In this embodiment, during operation, the operator presses the button while holding the handheld part 331. The brakes 41 of the first braking mechanism 23, the third braking mechanism 4, the third braking mechanism 323, and the fourth braking mechanism 333 rotate as the position of the feed mechanism 2 and the control mechanism 3 is adjusted. When the desired position is reached, the operator releases the button and controls the brakes 41 of the first braking mechanism 23, the second braking mechanism 4, the third braking mechanism 323, and the fourth braking mechanism 333 to lock, thereby positioning the main operating hand.
