Abstract
Description
Technical Field
[0001] The present invention relates to a manipulation device, in particular to a manipulation device used for minimally invasive surgery. Background Art
[0002] Surgical forceps are surgical instruments commonly used in endoscopic surgery. Traditional laparoscopic forceps consist of functional units—such as a knife, scissors, forceps, or needle and thread—fixed to the end of a rigid straight rod. These units are operated via a handheld portion at the other end, typically with only one degree of freedom: the opening and closing of the functional units. Because the ends of the straight rod connecting the functional units are rigid, the local degrees of freedom at the distal end of these forceps are very limited, significantly reducing operational flexibility. To improve the operational freedom of surgical forceps, researchers have proposed multi-degree-of-freedom surgical forceps for use with robotic minimally invasive surgery. These forceps increase their freedom of movement by adding movable joints to the distal end. However, more degrees of freedom means more movable joints, significantly increasing their overall size and control difficulty. Furthermore, to maintain operational precision, the forceps need to be regularly replaced, increasing surgical costs. For example, the surgical arms of the da Vinci surgical robot have a diameter of 5 mm or 8 mm, and each arm is limited to 10 uses. However, for neurosurgery and pediatric surgery, limited operating space often requires the smallest possible forceps size while maintaining operational flexibility.
[0003] Therefore, it is necessary to provide a manipulation device for minimally invasive surgery that has a simple structure and flexible manipulation. Summary of the Invention

[0050] Detailed description of specific implementation methods and embodiments
[0051] Unless otherwise indicated, the lateral direction X, transverse direction Y, and longitudinal direction Z cited or referred to herein are as follows: Figure 1 、 Figure 10 、 Figure 17A 、 Figure 18 and Figure 22 The directions shown are in an XYZ coordinate system, wherein the lateral direction X and the transverse direction Y are perpendicular to each other and to the longitudinal direction Z.
[0052] like Figures 1 to 5 As shown, according to one embodiment, the control device 100 of the present invention includes a body 110, a control member 120, an actuator 130 and a transmission member 140 ( Figure 4A The body 110 is an elongated cylinder having a channel 114 extending along a longitudinal direction Z between a first end 112 and a second end 116 of the body 110. The channel 114 has a first opening at the first end 112 of the body 110, for example, four first openings evenly distributed along a circumference parallel to the XY plane and about the geometric center of the first end 112, namely, a first transverse left opening 1121, a first lateral left opening 1122, a first transverse right opening 1123, and a first lateral right opening 1124. The channel 114 has a second opening at the second end 116 of the body 110, for example, four second openings evenly distributed along a circumference parallel to the XY plane and about the geometric center of the second end 116, namely, a second transverse left opening 1161, a second lateral left opening 1162, a second transverse right opening 1163, and a second lateral right opening 1164. The transmission member 140 may include a first transmission member 1401, a second transmission member 1402, a third transmission member 1403, and a fourth transmission member 1404. The first to fourth transmission members 1401, 1402, 1403, and 1404 can respectively pass through the four first openings 1121, 1122, 1123, and 1124 and the four second openings 1161, 1162, 1163, and 1164 to pass through the main body, that is, the first transmission member 1401 passes through the main body 110 from the first horizontal left opening 1121 and the second horizontal left opening 1161, the second transmission member 1402 passes through the main body 110 from the first side left opening 1122 and the second side left opening 1162, the third transmission member 1403 passes through the main body 110 from the first horizontal right opening 1123 and the second horizontal right opening 1163, and the fourth transmission member 1404 passes through the main body 110 from the first side right opening 1124 and the second side right opening 1164.
[0053] The manipulation device 100 may further include a tool portion 190 detachably connected to the actuator 140. The tool portion 190 may include at least one of the following or a combination thereof: for example, a knife, scissors, pliers, needle and thread, etc. The tool portion may be a surgical instrument, such as Figures 1 to 3 The surgical clamp 190 is shown in FIG.
[0054] like Figure 4A 、 Figure 4B and Figure 5 As shown, the middle section of the channel 114 between the first end 112 and the second end 116 of the body 110 can be independent channels separated from each other, for example Figure 4A The four independent channels shown are the first channel 1141, the second channel 1142, the third channel 1143, and the fourth channel 1144. The first channel 1141, the second channel 1142, the third channel 1143, and the fourth channel 1144 are all parallel to the longitudinal direction Z. Each transmission member 140 is movably disposed in the channel 114. Specifically, the transmission member 140 may include a first transmission member 1401, a second transmission member 1402, a third transmission member 1403, and a fourth transmission member 1404, which are respectively disposed in the first channel 1141, the second channel 1142, the third channel 1143, and the fourth channel 1144. Figure 5 shown.
[0055] Figure 6 According to the present invention, there is Figure 5 A partially cutaway stereoscopic view of the control device showing the main body structure. Figure 7 yes Figure 6 A partially cutaway perspective view of the control device shown with the clamp installed. Figure 8 yes Figure 7 Exploded three-dimensional diagram. Figure 9 yes Figure 7 A partially cutaway perspective view of the control assembly is shown after the clamp has been repositioned.
[0056] like Figures 6 to 8 As shown, the control member 120 is located adjacent to the first end 112 of the main body 110, and the actuator 130 is located adjacent to the second end 116 of the main body 110. The control member 120 is separated from the first end 112 of the main body by a first gap 125 along the longitudinal direction Z, and the actuator 130 is separated from the second end 116 of the main body by a second gap 135 along the longitudinal direction Z. The lengths of the first gap 125 and the second gap 135 can be equal or different. The transmission member 140 is provided through the channel of the main body 110, and both ends of the transmission member 140 are respectively fixed to the actuator 120 and the control member 130 along the longitudinal direction Z. For example, one side of the control member 120 and / or one side of the actuator 130 can each include a channel corresponding to the transmission member 140, for accommodating and fixing the transmission member 140.
[0057] like Figure 9 As shown, the displacement of the control member 120 relative to the body 110 drives the displacement of one or more transmission members 140 relative to the body 110, and then drives the actuator 130 and the tool portion 190 connected to the actuator 130 to move relative to the body 110. According to a specific example, the rotation of the control member 120 relative to the body 110 along the direction 120a, that is, Figure 9 The counterclockwise rotation 120a drives the first transmission member 1401 to move relative to the body 110 in the direction of pulling out the actuator 130, and simultaneously drives the third transmission member 1403 to move relative to the body 110 in the direction of pushing the actuator in. The displacement of the first transmission member 1401 and the third transmission member 1403 simultaneously drives the actuator 130 and the surgical clamp 190 mounted on the actuator 130 to rotate relative to the body 110 in the same direction as the control member 120, i.e. Figure 9 140a. Similarly, the displacement of the control member 120 relative to the body 110 in other directions in the XYZ three-dimensional space will drive the independent displacement of one or more of the first transmission member 1401, the second transmission member 1402, the third transmission member 1403, and the fourth transmission member 1404 relative to the body 110, thereby driving the actuator 130 to make corresponding displacements in the same direction as the control member 120. Thus, the displacement of the control member 120 relative to the body 110 is transmitted to the actuator 130 via the first transmission member 1401, the second transmission member 1402, the third transmission member 1403, and the fourth transmission member 1404, thereby achieving distanced control of the surgical clamp 190. As used herein, the term "distanced control" refers to the controlled displacement or movement of the actuator of the manipulation device of the present invention at a distance from the control member.
[0058] According to an alternative solution, Figure 10 and Figure 11As shown, the middle section of the channel 114 between the first end 112 and the second end 116 of the body 110 can be a single-bore channel. In the middle section of the body 110, the first transmission member 1401, the second transmission member 1402, the third transmission member 1403, and the fourth transmission member 1404 are located in a common space. According to this embodiment, the first transmission member 1401, the second transmission member 1402, the third transmission member 1403, and the fourth transmission member 1404 are all disposed longitudinally and parallel to each other in the body 110. Taking the first transmission member 1401 as an example, it passes through the first transverse left opening 1121 at the first end 112 of the body 110 and the second transverse left opening 1161 at the second end 116 of the body 110, located at a corresponding position and on the same side as the central longitudinal axis 110Z. The second transmission member 1402, the third transmission member 1403 and the fourth transmission member 1404 respectively pass through the first side left opening 1122, the first horizontal right opening 1123, the first side right opening 1124 of the first end 112 of the main body 110, and the second side left opening 1162, the second horizontal right opening 1163, the second side right opening 1164 of the second end 116 of the main body 110 in the same manner and relative position relationship.
[0059] With Figure 10 and Figure 11 The control device of the main body 110, the displacement direction of the control member 120 and the actuator 130 are shown in FIG. Figure 9 The same direction as shown. Figure 12 As shown, the control member 120 rotates relative to the body 110 in the direction 120a, that is, Figure 12 The counterclockwise rotation 120a drives the first transmission member 1401 to move relative to the body 110 in the direction of pulling out the body 110, and simultaneously drives the third transmission member 1403 to move relative to the body 110 in the direction of pushing the body 110. The displacement of the first transmission member 1401 and the third transmission member 1403 simultaneously drives the actuator 130 and the surgical clamp 190 mounted on the actuator 130 to rotate relative to the body 110 in the same direction as the control member 120, that is, Figure 12 The counterclockwise direction 130a is shown. Similarly, the displacement of the control member 120 relative to the body 110 in other directions in the XYZ three-dimensional space will drive the independent displacement of one or more of the first transmission member 1401, the second transmission member 1402, the third transmission member 1403, and the fourth transmission member 1404 relative to the body 110, thereby driving the actuator 130 to move accordingly. Thus, the displacement of the control member 120 relative to the body 110 is transmitted to the actuator 130 via the first transmission member 1401, the second transmission member 1402, the third transmission member 1403, and the fourth transmission member 1404, thereby controlling the spacing of the surgical clamp 190.
[0060] Figure 13FIG. 2 is a three-dimensional schematic diagram of the motion state of a control device 200 according to another embodiment of the present invention. Figure 14 yes Figure 13 The schematic diagram of the partially exploded perspective view of the control device is shown in FIG. Figure 14 As shown, the body 210 of the control device 200 has four first openings evenly distributed along a circumference parallel to the XY plane and about the geometric center of the first end 212: a first transverse left opening 2121, a first lateral left opening 2122, a first transverse right opening 2123, and a first lateral right opening 2124. Furthermore, the body 210 has four second openings evenly distributed along a circumference parallel to the XY plane and about the geometric center of the second end 216: a second transverse left opening 2161, a second lateral left opening 2162, a second transverse right opening 2163, and a second lateral right opening 2164. A first transmission member 2401, a second transmission member 2402, a third transmission member 2403, and a fourth transmission member 2404 extend through the first openings 2121, 2122, 2123, and 2124, respectively, at the first end 212 of the body 210. The body 210 has a single inner bore 214 located midway between the first end 212 and the second end 216. The first transmission member 2401, the second transmission member 2402, the third transmission member 2403 and the fourth transmission member 2404 are arranged in a cross manner in the inner bore 214, that is, the first transmission member 2401 passing through the first transverse left opening 2121 at the first end 212 of the main body 210 changes its orientation in the inner bore 214, so that the first transmission member 2401 passes through the main body 210 at the second end 216 of the main body 210 from the second transverse right opening 2163 which is symmetrical to the first transverse left opening 2121 about the longitudinal axis 210Z.
[0061] Similarly, the second transmission member 2402, which passes through the first lateral left opening 2122 at the first end 212 of the body 210, changes its orientation within the inner bore 214, such that the second transmission member 2402 exits the body 210 at the second end 216 of the body 210 through a second lateral right opening 2164, which is symmetrical with the first lateral left opening 2122 about the longitudinal axis 210Z. The third transmission member 2403, which passes through the first transverse right opening 2123 at the first end 212 of the body 210, changes its orientation within the inner bore 214, such that the third transmission member 2403 exits the body 210 at the second end 216 of the body 210 through a second transverse left opening 2161, which is symmetrical with the first transverse right opening 2123 about the longitudinal axis 210Z. The fourth transmission member 2404 passing through the fourth side right opening 2124 of the first end 212 of the main body 210 changes its orientation in the inner chamber 214 so that the fourth transmission member 2404 passes through the main body 210 at the second end 216 of the main body 210 from the second side left opening 2162 which is symmetrical to the first side right opening 2124 about the longitudinal axis 210Z.
[0062] With Figure 13 and Figure 14 The control device 200 of the main body 210 and the transmission member structure shown in FIG. 20 is configured such that the control member 220 rotates relative to the main body 210 along the direction 220a. Figure 13 The counterclockwise rotation 220a drives the first transmission member 2401 to move relative to the body 210 in the direction of pulling out of the body 210, and simultaneously drives the third transmission member 2403 to move relative to the body 210 in the direction of pushing into the body 210. Since the first transmission member 2401, the second transmission member 2402, the third transmission member 2403 and the fourth transmission member 2404 are arranged in a cross pattern in the inner chamber 214, the displacement of the first transmission member 2401 and the third transmission member 2403 simultaneously drives the actuator 230 and the surgical clamp 290 mounted on the actuator 230 to rotate relative to the body 210 in the opposite direction to the control member 220, that is, Figure 13 Similarly, the displacement of the control member 220 relative to the body 210 in other directions in the XYZ three-dimensional space will drive the independent displacement of one or more of the first transmission member 2401, the second transmission member 2402, the third transmission member 2403, and the fourth transmission member 2404 relative to the body 210, thereby driving the actuator 230 to make corresponding displacements in the opposite direction of the control member 220. Thus, the displacement of the control member 220 relative to the body 210 is transmitted to the actuator 230 via the first transmission member 2401, the second transmission member 2402, the third transmission member 2403, and the fourth transmission member 2404, thereby controlling the spacing of the surgical clamp 290.
[0063] According to an alternative solution, Figure 15A 、 Figure 15B 、 Figure 16A and Figure 16B As shown, the control device 200 may further include one or more sleeves 2411, 2412, 2413, 2414, each sleeve 2411, 2412, 2413, 2414 being respectively sleeved on the outside of the first transmission member 2401, the second transmission member 2402, the third transmission member 2403 and the fourth transmission member 2404, so that the first transmission member 2401, the second transmission member 2402, the third transmission member 2403 and the fourth transmission member 2404 can be displaced relative to their respective sleeves 2411, 2412, 2413, 2414 along the longitudinal axis of each transmission member. The middle section of the body 210 is a single inner bore. One or more sleeves 2411, 2412, 2413, 2414 are passed through and fixed to the body 210. The plurality of sleeves 2411, 2412, 2413, 2414 can be arranged according to Figure 16A As shown, they are fixed in parallel to each other inside the body 210, thereby achieving Figure 12 Alternatively, multiple sleeves 2411, 2412, 2413, 2414 can be operated in the manner shown. Figure 16B In the manner shown, the middle sections of the single inner bore of the body 210 intersect with each other and are fixed inside the body 210, thereby achieving the same Figure 5 The same control method as shown in the figure can achieve the following Figure 13 The control method shown.
[0064] According to yet another embodiment, Figure 17A 、 Figure 17B 、 Figure 17C 、 Figure 18 and Figure 19 As shown, the control device 300 of the present invention includes a main body 310, a transmission member 340 passing through the main body 310, a control member 320 fixed to one end of the transmission member 340 and adjacent to the first end 312 of the main body 310, an actuator 330 fixed to the other end of the transmission member 340 and adjacent to the second end 316 of the main body 310, a support 360 fixed to the first end 312 of the main body 310, a bracket 370 pivotally connected to the support 360, and a handle 380 pivotally connected to the bracket 370.
[0065] like Figure 18 and Figure 19 As shown, the support 360 has a support base 362 and a pair of support legs 364 extending from the base 362. A first support shaft hole 366 is formed at the end of each support leg 364. The bracket 370 has a hollow core 372, a pair of first bracket shaft holes 376 and a second bracket shaft hole 378 spaced symmetrically about the core 372. The handle 380 has a handle base 382 and a pair of handle legs 384 extending from the handle base 382. A second support shaft hole 388 is formed at the end of each handle leg 384.
[0066] A pair of first bracket shaft holes 376 are arranged in the transverse direction, i.e. Figure 18 and Figure 19 A pair of second bracket shaft holes 378 are arranged in the X direction as shown. Figure 18 and Figure 19 The bracket 370 is pivotally connected to the support 360 via the first bracket shaft hole 376 , the first support shaft hole 366 and a pair of first pivots 356 along the X direction, that is, the bracket 370 can pivot relative to the support 360 about the pair of first pivots 356 .
[0067] The handle 380 is pivotally connected to the bracket 370 through the second bracket shaft hole 388 , the second support shaft hole 376 and a pair of second pivots 358 along the Y direction. That is, the handle 380 can pivot relative to the bracket 370 about the pair of second pivots 358 .
[0068] The body 310 is fixed relative to the support 360. The first end 312 of the body 310 is located between a pair of support struts 364. The actuator 320 is fixed relative to the handle 380. The actuator 380 is located between a pair of second struts 384. The transmission member 340, which connects the body 310 and the control member 320, is suspended in the hollow core 372 of the support.
[0069] According to the structure of this embodiment as described above, Figure 20 、 Figure 21 and Figure 22 As shown, the handle 380 drives the bracket 370 to pivot relative to the body 310 about the pair of first pivots 356, thereby driving the control member 320 to rotate relative to the body 310. The rotation of the control member 320 in turn drives the transmission member 340 to move relative to the body 310. The displacement of the transmission member 340 relative to the body 310 drives the actuator 330 and the surgical instrument 390 mounted thereon to rotate in a direction that is the same as or opposite to the pivot direction of the handle 380, thereby achieving displacement control of the surgical instrument 390 in the YZ plane, as shown in FIG21.
[0070] Similarly, the pivoting of the handle 380 relative to the body 310 about the pair of second pivots 358 causes the control member 320 to rotate relative to the body 310. The rotation of the control member 320 in turn causes the transmission member 340 to move relative to the body 310. The displacement of the transmission member 340 relative to the body 310 causes the actuator 330 and the surgical instrument 390 mounted thereon to rotate in a direction that is the same as or opposite to the pivoting direction of the handle 380, thereby achieving displacement control of the surgical instrument 390 in the XZ plane, as shown in FIG22 .
[0071] The combination of independent pivoting of the handle 380 relative to the body 310 about the pair of first pivots 356 and the pair of second pivots 358 can achieve the control of the surgical instrument 390 in any orientation in the XYZ space.

One end of the grip 570 is fixed to the support 560 along the longitudinal direction Z+ / Z- and surrounds at least a portion of the outer circumference of the body 510. Figure 24 In the illustrated example, the second end 516 of the body 510 faces the Z+ direction, toward the front end of the control device 500. Due to the U-shaped bend of the body 510, the first end 512 of the body 510 faces the same direction as the second end 516. That is, both the first end 512 and the second end 516 of the body 510 face the Z+ direction, toward the front end of the control device 500. With this structure, the control device 500 is suitable for grasping the grip 510 with the palm and index, middle, ring, and pinky fingers of a user, allowing the user to manipulate the handle 580 with their thumb to control the position of the actuator 530 and surgical clamp 590 at the front end of the body 510.

Due to the U-shaped bend of the body 610, the first end 612 of the body 610 faces approximately the same direction as the second end 616. That is, the first end 612 of the body 610 also faces the Z+ direction toward the front end of the control device 600. With this structure, the control device 600 is suitable for a user to secure their wrist to the wristband 652 and to grasp the control handle 680 to control the position of the actuator 630 and surgical clamp 690 at the front end of the body 610.
