Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a sterile cover rotating structure and a surgical robot. Background Art

[0002] Minimally invasive surgery refers to a procedure performed inside the human body using medical instruments such as laparoscopes and thoracoscopes and related equipment. During robotic-assisted minimally invasive surgery, doctors use slender minimally invasive instruments to perform the procedure, while maintaining sterile conditions in the area adjacent to the patient.

[0003] In related art, a surgical robot includes a main body, a first component, and a second component. The first component may be a connecting arm, and the second component may be a rotating arm. The connecting arm is movably connected to the main body, and the rotating arm is rotationally connected to the connecting arm. A sterile cover encloses the connecting arm and the rotating arm. One end of the sterile cover is fixedly connected to the main body, and one end of the sterile cover is fixedly connected to the rotating arm.

[0004] However, when the connecting arm of the surgical robot does not move, the sterile cover is twisted during the rotation of the rotating arm, causing the sterile cover to interfere with the movement of the rotating arm, thereby affecting the movement of the surgical robot. Summary of the Invention

[0005] An embodiment of the present invention provides a sterile cover rotation structure and a surgical robot to solve the problem that when the connecting arm of the surgical robot does not move and the rotating arm rotates, the sterile cover is twisted, causing interference between the sterile cover and the rotating arm, thereby affecting the movement of the surgical robot.

[0006] In a first aspect, an embodiment of the present invention provides a sterile cover rotation structure, comprising a first sterile cover, a second sterile cover, a first connecting member, and a second connecting member;

[0007] The first sterile cover is fixedly connected to the first connecting member, the first sterile cover is used to wrap the first component of the surgical robot, and the first connecting member is connected to the first component;

[0009] The sterile cover rotation structure provided by an embodiment of the present invention is rotatably connected by a first connecting member and a second connecting member, so that the first connecting member and the second connecting member can rotate relative to each other. When the first part of the surgical robot is not moving and the second part is rotating, the first connecting member and the first sterile cover remain stationary relative to the first part, and the first sterile cover does not move with the second part. The second connecting member and the second sterile cover rotate with the second part, that is, the second sterile cover maintains synchronous movement with the second part, so that the first sterile cover and the second sterile cover do not interfere with the movement of the second part, thereby eliminating the influence of the sterile cover on the movement of the surgical robot.

[0010] In a possible embodiment, a rotation groove is provided inside the first connecting member, and the second connecting member is rotatably disposed in the rotation groove, so that the second connecting member can rotate relative to the first connecting member.

[0011] In a possible embodiment, a gap is provided between the second connecting member and the sidewall of the rotation groove in the axial direction of the first connecting member. This configuration can reduce friction between the second connecting member and the sidewall of the rotation groove, allowing the second connection to rotate smoothly.

[0012] In one possible embodiment, the second connector is provided with an annular wall, the axis of which coincides with the axis of the first connector, and the annular wall contacts the inner wall of the first connector. This arrangement can limit the second connector in the radial direction of the first connector, preventing the second connector from shaking in the radial direction of the first connector, thereby improving the rotational stability of the second connector.

[0013] In one possible embodiment, the first sterile cover is thermally bonded to the outer wall of the first connector. This arrangement ensures that there is no gap at the connection between the first sterile cover and the first connector, thereby improving the sealing between the first sterile cover and the first connector and preventing external contaminants from entering the sterile environment.

[0014] In one possible embodiment, the second sterile cover includes a plurality of cover bodies, and the second connector is provided with a plurality of mounting openings, wherein the plurality of cover bodies correspond one-to-one to the plurality of mounting openings, one end of each cover body is thermally bonded to the side wall of the corresponding mounting opening, and the other end of each cover body is thermally bonded to the isolation plate, and the isolation plate is connected to the second component. With such a configuration, the thermal bonding method can ensure that there is no gap at the connection between the second sterile cover and the second connector, and there is no gap at the connection between the second sterile cover and the isolation plate, thereby improving the sealing between the second sterile cover and the second connector, and improving the sealing between the second sterile cover and the isolation plate, thereby preventing external contaminants from entering the sterile environment.

[0015] In one possible embodiment, the first connector is detachably connected to the first component, and the second connector is detachably connected to the second component. This arrangement allows the first sterile cover to be easily installed and removed from the first component via the first connector, and allows the second sterile cover to be easily installed and removed from the second component via the second connector.

[0016] In one possible embodiment, the first connector is internally provided with a plurality of engaging arms, spaced apart along the circumference of the first connector, and engaging with the first component. This arrangement allows for quick installation and removal of the first connector and the first component through engagement and disengagement. The engagement of the plurality of engaging arms with the first component provides multi-point support and fixation, thereby enhancing the stability between the first connector and the first component and reducing the risk of loosening or falling off.

[0017] In one possible embodiment, the second connector is provided with a plurality of spaced-apart plugging protrusions, which are plugged into the second component. In this manner, when the second component rotates, the second component can drive the second connector to rotate, so that the second connector 40 rotates synchronously with the second component.

[0018] In a second aspect, an embodiment of the present invention provides a surgical robot comprising a first component, a second component, and the sterile cover rotating structure as described above;

[0019] The second component is rotatably connected to the first component, the first sterile cover of the sterile cover rotating structure wraps the first component, the first connecting piece of the sterile cover rotating structure is connected to the first component, the second sterile cover of the sterile cover rotating structure wraps the second component, and the second connecting piece of the sterile cover rotating structure is connected to the second component.

[0020] The surgical robot provided by an embodiment of the present invention is rotatably connected to the first connecting member and the second connecting member so that the first connecting member and the second connecting member can rotate relative to each other. When the first component of the surgical robot is not moving and the second component is rotating, the first connecting member and the first sterile cover remain stationary relative to the first component, and the first sterile cover does not move with the second component. The second connecting member and the second sterile cover rotate with the second component, that is, the second sterile cover maintains synchronous movement with the second component, so that the first sterile cover and the second sterile cover do not interfere with the movement of the second component, thereby eliminating the influence of the sterile cover on the movement of the surgical robot.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0045] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of such features.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0047] In the present invention, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediary. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine different embodiments or examples and features of different embodiments or examples described in this specification without mutual contradiction.

[0049] In related art, when the surgical robot's connecting arm is stationary, the swivel arm rotates, causing the sterile cover to interfere with the robot's movements, affecting the robot's motion. The inventors discovered that this problem arises because one end of the sterile cover rotates while the other does not. When the surgical robot's connecting arm is stationary, the swivel arm rotates, causing the sterile cover to twist, causing interference between the two arms and affecting the robot's motion.

[0050] In order to solve the above problems, an embodiment of the present invention provides a sterile cover rotation structure and a surgical robot, which divides the sterile cover into two independent first sterile covers and a second sterile cover. When the first part of the surgical robot is not moving and the second part is rotating, the first sterile cover remains stationary relative to the first part, the first sterile cover does not move with the second part, and the second sterile cover rotates with the second part, that is, the second sterile cover maintains synchronous movement with the second part, so that the first sterile cover and the second sterile cover do not interfere with the movement of the second part, eliminating the influence of the sterile cover on the movement of the surgical robot.

[0051] The sterile cover rotation structure and surgical robot provided by the embodiments of the present invention are described in detail below with reference to specific embodiments.

[0052] See also Figure 1 and Figure 2As shown, an embodiment of the present invention provides a sterile cover rotating structure for use in a surgical robot. The sterile cover rotating structure includes a first sterile cover 10 , a second sterile cover 20 , a first connecting member 30 , and a second connecting member 40 .

[0053] See also Figure 3 and Figure 4 As shown, the surgical robot includes a main body, a first component 100 and a second component 200. The first component 100 can be a connecting arm, and the second component 200 can be a rotating arm. The connecting arm is movably connected to the main body, and the rotating arm is rotatably connected to the connecting arm. Figure 3 and Figure 4 The middle connecting arm and the rotating arm are shown in partial schematic diagrams.

[0054] During the movement of the surgical robot, the first component 100 may not move, and the second component 200 may perform rotational movement.

[0055] See also Figure 1 and Figure 3 As shown, the first sterile cover 10 is fixedly connected to the first connecting member 30 . The first sterile cover 10 is used to wrap the first component 100 of the surgical robot. The first connecting member 30 is connected to the first component 100 .

[0056] The first sterile cover 10 can be made of plastic.

[0057] One end of the first sterile cover 10 is fixedly connected to the first connector 30. The first sterile cover 10 can be fixedly connected to the first connector 30 by bonding, thermal bonding, binding or tape wrapping.

[0058] The other end of the first sterile cover 10 is fixedly connected to the main body of the surgical robot. The first sterile cover 10 can be fixedly connected to the main body of the surgical robot by bonding, thermal bonding, binding or tape wrapping.

[0059] The first connecting member 30 can be connected to the first component 100 by means of clamping, welding or bonding.

[0060] When the first part 100 of the surgical robot is not moving, the first sterile cover 10, the first connecting member 30 and the first part 100 are all in a stationary state, that is, the first sterile cover 10 and the first connecting member 30 remain stationary relative to the first part 100, and the first sterile cover 10 will not interfere with the first part 100.

[0061] The second sterile cover 20 is fixedly connected to the second connecting member 40, which is rotatably connected to the first connecting member 30. The second sterile cover 20 is used to wrap the second component 200 of the surgical robot, and the second connecting member 40 is connected to the second component 200. It should be noted that a portion of the second component 200 is located inside the first component 100 (see Figure 4 and Figure 12 The second sterile cover 20 wraps the portion of the second component 200 located outside the first component 100 .

[0062] The second sterile cover 20 may be made of plastic.

[0063] One end of the second sterile cover 20 is fixedly connected to the second connector 40. The second sterile cover 20 can be fixedly connected to the second connector 40 by bonding, thermal bonding, binding, or wrapping with adhesive tape.

[0064] The other end of the second sterile cover 20 is connected to the isolation plate 50 (see Figure 1 As shown in FIG, 20 is fixedly connected to the second component 200. The second sterile cover 20 can be fixedly connected to the isolation plate 50 by bonding, heat bonding, tying or wrapping with adhesive tape.

[0065] The second connecting member 40 rotates relative to the first connecting member 30 , so that the second sterile cover 20 can rotate relative to the first sterile cover 10 , thereby preventing the second sterile cover 20 and the first sterile cover 10 from interfering with each other.

[0066] The second connecting member 40 can be connected to the second component 200 by means of snap connection or bonding. The second connecting member 40 rotates synchronously with the second component 200. It is understandable that the second connecting member 40 remains stationary relative to the second component 200.

[0067] When the first component 100 of the surgical robot is not moving and the second component 200 is rotating, the second component 200 drives the second connecting member 40 to rotate, and the second connecting member 40 drives the second sterile cover 20 to rotate. The second component 200, the second connecting member 40 and the second sterile cover 20 rotate synchronously, that is, the second connecting member 40 and the second sterile cover 20 remain stationary relative to the second component 200, and the second connecting member 40 and the second sterile cover 20 rotate relative to the first sterile cover 10 and the first connecting member 30, so that the second sterile cover 20 will not interfere with the second component 200, and the second sterile cover 20 and the first sterile cover 10 do not interfere with each other.

[0068] The sterile cover rotation structure provided by an embodiment of the present invention is rotatably connected by the first connecting member 30 and the second connecting member 40, so that the first connecting member 30 and the second connecting member 40 can rotate relative to each other. When the first component 100 of the surgical robot is not moving and the second component 200 is rotating, the first connecting member 30 and the first sterile cover 10 remain stationary relative to the first component 100, and the first sterile cover 10 does not move with the second component 200. The second connecting member 40 and the second sterile cover 20 rotate with the second component 200, that is, the second sterile cover 20 maintains synchronous movement with the second component 200, so that the first sterile cover 10 and the second sterile cover 20 do not interfere with the movement of the second component 200, thereby eliminating the influence of the sterile cover on the movement of the surgical robot.

[0069] In one possible implementation, see Figure 5 and Figure 6 As shown, a rotation groove 30 a is provided inside the first connecting member 30 . The second connecting member 40 is rotatably disposed in the rotation groove 30 a . This arrangement allows the second connecting member 40 to rotate relative to the first connecting member 30 .

[0070] The first connector 30 is detachably connected to the first component 100 , so that the first sterile cover 10 can be easily installed and removed from the first component 100 through the first connector 30 .

[0071] For some examples, see Figure 3 and Figure 7 As shown, the first connecting member 30 is engaged with the first component 100 .

[0072] In one embodiment, the first connecting member 30 is arranged in a circular ring shape. Figures 5 to 7 As shown, the first connector 30 includes a first connector body 301 and a plurality of engaging arms 302. The plurality of engaging arms 302 are spaced apart along the circumference of the first connector 30, and the plurality of engaging arms 302 engage with the first component 100. This arrangement allows for quick installation and removal of the first connector 30 and the first component 100 through engagement and separation. The engagement of the plurality of engaging arms 302 with the first component 100 provides multi-point support and fixation, thereby enhancing the stability between the first connector 30 and the first component 100 and reducing the risk of loosening or falling off.

[0073] The locking arm 302 is located inside the first connecting body 301. The locking arm 302 includes a first end and a second end, wherein the first end is fixedly connected to the first connecting body 301 and the second end is in a free state.

[0074] See also Figure 5 and Figure 6 As shown, the first end of the locking arm 302 and the first connecting body 301 form a rotation groove 30a.

[0075] See also Figure 6 and Figure 7 As shown, the second end of the locking arm 302 is provided with a locking protrusion 3021, and the outer side of the first component 100 is provided with a locking groove 101 corresponding to the locking protrusion 3021, and the locking protrusion 3021 is locked in the locking groove 101. This arrangement allows the first connecting member 30 to be fixed to the first component 100, and the first connecting member 30 and the first component 100 are relatively stationary.

[0076] The first sterile cover 10 is thermally bonded to the outer wall of the first connecting body 301 of the first connecting member 30. In this way, the thermal bonding method can ensure that there is no gap at the connection between the first sterile cover 10 and the first connecting member 30, thereby improving the sealing between the first sterile cover 10 and the first connecting member 30 and preventing external contaminants from entering the sterile environment.

[0077] In some examples, the first connector 30 includes a first connector body 301 and four engaging arms 302 , wherein the four engaging arms 302 are integrally formed with the first connector body 301 . The four engaging arms 302 are arranged at equal intervals along the circumference of the first connector 30 .

[0078] In one possible implementation, see Figure 8 and Figure 9 As shown, there is a gap between the second connecting member 40 and the side wall of the rotation groove 30a in the axial direction of the first connecting member 30. This arrangement can reduce the friction between the second connecting member 40 and the side wall of the rotation groove 30a, allowing the second connecting member 40 to rotate smoothly.

[0079] Among them, see Figure 10 As shown, the second connecting member 40 includes a second connecting body 401. The second connecting body 401 is cylindrical and is located inside the first connecting member 30. The second connecting body 401 is coaxial with the first connecting member 30.

[0080] The second connecting body 401 is inserted into the rotation groove 30a. In the axial direction of the first connecting member 30, a gap is formed between the second connecting body 401 and the side wall of the rotation groove 30a.

[0081] The second connecting member 40 further includes an annular wall 402. The annular wall 402 is annular and is located on one side of the second connecting body 401 in the axial direction.

[0082] See also Figure 10 and Figure 11 As shown, the annular wall 402 is coaxially arranged with the second connecting body 401. The axis of the annular wall 402 coincides with the axis of the first connecting member 30.

[0083] The diameter of the annular wall 402 is smaller than the diameter of the second connecting body 401 .

[0084] The annular wall 402 contacts the inner wall of the first connector 30. Specifically, in the radial direction of the first connector 30, the annular wall 402 contacts the engaging arm 302 of the first connector 30. This arrangement can limit the second connector 40 in the radial direction of the first connector 30, preventing the second connector 40 from shaking in the radial direction of the first connector 30, thereby improving the rotational stability of the second connector 40.

[0085] The second connecting body 401 is provided with a plurality of mounting ports 4011. The second sterile cover 20 comprises a plurality of cover bodies 20a (see Figure 2 As shown in FIG, a plurality of cover bodies 20a correspond to a plurality of mounting openings 4011 in a one-to-one manner, one end of each cover body 20a is thermally bonded to the side wall of the corresponding mounting opening 4011, and the other end of each cover body 20a is thermally bonded to the isolation plate 50, which is then engaged and connected to the second component 200. With this arrangement, the thermal bonding method can ensure that there is no gap at the connection between the second sterile cover 20 and the second connector 40, and there is no gap at the connection between the second sterile cover 20 and the isolation plate 50, thereby improving the sealing between the second sterile cover 20 and the second connector 40, as well as improving the sealing between the second sterile cover 20 and the isolation plate 50, and preventing external contaminants from entering the sterile environment.

[0086] In the axial direction of the second connecting body 401 , the installation opening 4011 passes through the second connecting body 401 .

[0087] A portion of the second component 200 is rotatably located inside the first component 100 , and a portion of the second component 200 is located outside the first component 100 . This portion is wrapped by a plurality of covers 20 a , so that the second component 200 is in a sterile environment.

[0088] In some examples, the second connecting body 401 is provided with four mounting openings 4011. The second sterile cover 20 includes four cover bodies 20a, which correspond one to one with the four mounting openings 4011, and each cover body 20a is thermally bonded to the side wall of the corresponding mounting opening 4011.

[0089] The second connector 40 is detachably connected to the second component 200 , so that the second sterile cover 20 can be easily installed and removed from the second component 200 via the second connector 40 .

[0090] In some examples, the second connector 40 is plug-connected to the second component 200 .

[0091] The second connecting body 401 of the second connecting member 40 is provided with a plurality of spaced apart inserting protrusions 4012 . In the axial direction of the second connecting body 401 , the inserting protrusions 4012 and the annular wall 402 are located on the same side of the second connecting body 401 .

[0092] A plurality of plug-in protrusions 4012 are plugged into the second component 200 (see Figure 4 Specifically, see Figure 12 As shown, the second component 200 is provided with a plurality of insertion holes 201, and the plurality of insertion holes 201 correspond one-to-one to a plurality of insertion protrusions 4012, and each insertion protrusion 4012 is inserted into a corresponding insertion hole 201. In this arrangement, when the second component 200 rotates, the second component 200 can drive the second connecting member 40 to rotate, so that the second connecting member 40 and the second component 200 rotate synchronously.

[0093] When the first component 100 of the surgical robot is not moving and the second component 200 is rotating, the first sterile cover 10, the first connecting member 30, and the first component 100 are all in a stationary state. The second component 200 drives the second connecting member 40 to rotate through the plug-in protrusion 4012 of the second connecting member 40, and the second connecting member 40 drives the second sterile cover 20 to rotate. The second component 200, the second connecting member 40, and the second sterile cover 20 rotate synchronously. The second connecting member 40 and the second sterile cover 20 rotate relative to the first sterile cover 10 and the first connecting member 30, so that the second sterile cover 20 will not interfere with the second component 200, and the second sterile cover 20 and the first sterile cover 10 do not interfere with each other.

[0094] An embodiment of the present invention provides a surgical robot, comprising a first component 100, a second component 200 and a sterile cover rotating structure; the second component 200 is rotatably connected to the first component 100, the first sterile cover 10 of the sterile cover rotating structure wraps the first component 100, the first connecting member 30 of the sterile cover rotating structure is connected to the first component 100, the second sterile cover 20 of the sterile cover rotating structure wraps the second component 200, and the second connecting member 40 of the sterile cover rotating structure is connected to the second component 200.

They will not be described one by one here, and the details can be referred to the description of the above embodiments.

[0096] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
