Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a flip cover structure, an operating table and a surgical operating system. Background Art

[0002] Robotic laparoscopic surgery is a laparoscopic surgery assisted by surgical operating system technology. The surgical operating system is mainly composed of a console and a surgical robot. The surgeon sits in front of the console and uses the buttons and touch screen of the console to adjust the movement type, movement amplitude, and locking of the end instrument after closing.

[0003] In order to prevent the button from being triggered by mistake, a spring and a rotatable cover are usually provided to cover the button. Usually, the cover is designed to have two states, automatic opening and automatic closing, that is, when the opening angle of the cover is less than a preset angle (such as 20 degrees), the spring applies a restoring force to the cover. At this time, after the operator removes the force of the hand on the cover, the cover will automatically return to the closed state; when the opening angle of the cover reaches the preset angle, the spring applies a reverse restoring force to the cover. At this time, after the operator removes the force of the hand on the cover, the cover will automatically flip to the maximum opening angle (such as 90 degrees).

[0004] This solution realizes the automatic recovery of the cover, plays a certain role in preventing false triggering, and saves the operator some flipping operations. However, in actual use, it is found that after the cover is opened, the button is fully exposed, and there is still a great possibility of false triggering. If the operator frequently opens or closes the cover to avoid false triggering, the amount of operation will be significantly increased; in addition, when closing the cover, the operator needs to apply force from the maximum opening angle until the aforementioned preset angle, and the amplitude of each operation is also large, which is inconvenient to use.

[0054] It is particularly important to note that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0055] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0056] In order to illustrate the technical solution described in this application, a detailed description is given below in conjunction with specific drawings and embodiments.

[0057] The embodiment of the present application first provides a surgical operating system (not shown), which includes an operating table (not shown) and a surgical robot (not shown). The operating table is connected to the surgical robot. The operator controls the operating table to send various control signals to the surgical robot to control the surgical robot to perform corresponding actions.

[0058] In one embodiment, the operating console includes a flip cover structure 100 , one or more control buttons 9 , and a base (not shown), wherein the flip cover structure 100 is disposed on the base. The control buttons 9 are disposed in the flip cover structure 100 .

[0059] The flip cover structure 100 can be opened and closed. When the flip cover structure 100 is closed, the control button 9 is shielded. Figure 1 As shown, at this time, the control button 9 cannot be operated, and at the same time, the control button 9 will not be triggered by mistake; when the flip cover structure 100 is opened, the control button 9 is exposed and can be operated by the operator, such as Figure 2 shown.

[0060] See also Figures 1 to 3 As shown, the flip cover structure 100 provided in the embodiment of the present application includes a base 1, a rotating shaft 2 and a cover body 3. The rotating shaft 2 is rotatably mounted on the base 1 and has a rotation center axis X (see Figure 3 ), the cover body 3 is fixedly connected to the rotating shaft 2, and the cover body 3 flips as the rotating shaft 2 rotates to present a closed state and an open state.

[0061] The control button 9 is arranged between the base 1 and the cover 3. The base 1 may be at least a part of the base. Alternatively, the base 1 and the base are two separate structures fixedly connected together.

[0062] like Figure 4As shown, the outer circumference of the rotating shaft 2 has a generatrix, and the motion trajectory of the generatrix is ​​the rotation center axis X of the rotating shaft 2. In other words, the outer circumference of the rotating shaft 2 is defined by the movement of its generatrix along the rotation center axis X. The generatrix can be obtained by cutting the rotating shaft 2 perpendicular to its rotation center axis X.

[0063] Specific as Figure 4 As shown, in this embodiment, the generatrix of the outer circumferential surface of the rotating shaft 2 has a first critical point A and a second critical point B spaced apart in the circumferential direction, and a first segment DA, a second segment AB and a third segment BE divided by the first critical point A and the second critical point B. The first segment DA, the first critical point A, the second segment AB, the second critical point B and the third segment BE are arranged in sequence along the circumferential direction (the breakpoints of the first segment DA and the third segment BE on the side away from the first segment AB are connected or spaced apart by other points or lines); the second segment AB is an arc segment having a center O, which is located on the rotation center axis X of the rotating shaft 2.

[0064] Please continue reading Figure 4 As shown, in this embodiment, the distance from any point on the first segment DA to the rotation center axis X is smaller than the radius of the second segment AB, and the distance from any point on the third segment BE to the rotation center axis X is smaller than the radius of the second segment AB.

[0065] Also, see Figure 3 As shown, the flip cover structure 100 also includes an elastic member 4, which has a contact point abutting against the generatrix of the outer peripheral surface of the rotating shaft 2. The elastic member 4 is configured to provide a force perpendicular to the rotation center axis X of the rotating shaft 2 through the contact point, specifically a pressure perpendicular to the rotation center axis X of the rotating shaft 2.

[0066] The elastic member 4 acts on the rotating shaft 2 in the following manner.

[0067] The third section BE, the second section AB and the first section DA are arranged along the opening direction Y of the cover 3 (see Figure 4 That is, during the process of the cover body 3 being converted from the fully closed state to the fully opened state, the first section DA, the second section AB and the third section BE are in contact with the elastic member 4 in sequence. The following description takes the horizontal arrangement of the cover body 3 when it is fully closed as an example.

[0068] like Figure 8 , Fig. 9 and Fig.10As shown, the side of the elastic member 4 facing the rotating shaft 2 is configured to abut against the second section AB in a point contact (the point is the abutment point), and the elastic member 4 provides the rotating shaft 2 with a force F perpendicular to the rotation center axis X thereof via the abutment point. Since the second section AB is an arc segment, the direction of the force F passes through the rotation center axis X. Since the force F intersects the rotation center axis X perpendicularly, the torque formed by the force F on the rotating shaft 2 is 0, so that the force F will not cause the rotating shaft 2 to have any tendency to flip, that is, the force F will not cause the rotating shaft 2 to have any tendency to open or close.

[0069] On this basis, by setting the size matching between the rotating shaft 2 and the base 1, a certain static friction force is formed between the two, and the static friction force is used to offset the torque formed by the gravity of the rotating shaft 2 and the cover body 3 on the rotating shaft 2.

[0070] Finally, when the second section AB contacts the elastic member 4, the forces and moments on the shaft 2 and the cover 3 are balanced, and the shaft 2 and the cover 3 can remain suspended. This stage is defined as the second stage of the shaft 2, the suspension stage.

[0071] See also Figure 7 , and compare Figure 8 As shown, before the elastic member 4 contacts the second section AB, the elastic member 4 will face the first section DA. Since the distance from any point on the first section DA to the rotation center axis X is less than the radius of the second section AB, at this time, the contact point of the elastic member 4 still acts on the first critical point A, and provides a force F' perpendicular to the rotation center axis X to the rotating shaft 2 through the contact point. The force F' will not pass through the rotation center axis X, but will be offset from the rotation center axis X by a certain distance. Figure 7 As shown in , the force F' generates a torque M' on the shaft 2, and the torque M' causes the shaft 2 to have a tendency to flip. Since the first section DA contacts the shaft 2 before the second section AB, the torque M' causes the shaft 2 to have a tendency to close.

[0072] On this basis, by reasonably setting the magnitude of the static friction between the rotating shaft 2 and the base 1, the torque M' can overcome the effect of the static friction (of course, there is also the gravity torque of the rotating shaft 2 and the cover 3), thereby causing the rotating shaft 2 to automatically flip until it is closed. This stage is defined as the first stage of the rotating shaft 2, the automatic closing stage.

[0073] That is, when the rotation angle of the shaft 2 is not enough to make the elastic member 4 contact the second section AB, the shaft 2 will automatically return to the fully closed state (such as Figure 5 and Figure 6 shown).

[0074] Likewise, see Fig.11 , and compare Fig.10 As shown in FIG. 1 , after the elastic member 4 contacts the second section AB, the elastic member 4 will face the third section BE. Since the distance from any point on the third section BE to the rotation center axis X is less than the radius of the second section AB, at this time, the elastic member 4 provides a force F" perpendicular to the rotation center axis X of the rotating shaft 2 through the abutment point. The force F" will not pass through the rotation center axis X, but will be offset from the rotation center axis X by a certain distance. Fig.11 As shown in , the force F" generates a torque M" on the shaft 2, and the torque M" causes the shaft 2 to have a tendency to flip. Since the third section BE contacts the shaft 2 later than the second section AB, the torque M" causes the shaft 2 to have a tendency to open.

[0075] On this basis, by reasonably setting the magnitude of the static friction between the rotating shaft 2 and the base 1, the torque M" can overcome the effect of the static friction (of course, there is also the gravity torque of the rotating shaft 2 and the cover 3), so that the rotating shaft 2 automatically flips until it is fully opened. This stage is defined as the third stage of the rotating shaft 2, the automatic opening stage.

[0076] That is, when the rotation shaft 2 rotates to an angle such that the elastic member 4 has crossed and contacted the second section AB, the rotation shaft 2 will automatically continue to rotate, and the cover body 3 will automatically continue to flip over to the fully open state (such as Fig.12 shown).

[0077] Therefore, the flip cover structure 100 provided in the embodiment of the present application has a cover 3 with three states: automatic closing, hovering and automatic opening, providing three kinds of operation feel. First, in the hovering state, the cover 3 is opened at a certain angle, which allows certain manipulation of the control buttons 9 under the cover 3, and the risk of false triggering is significantly reduced at this time. The operator does not need to frequently open and close the cover 3, and only needs to fine-tune the angle of the cover 3 according to the operation needs; second, when the operator needs to close the cover 3, it is only necessary to flip the cover 3 from the hovering state to make the cover 3 reach the automatic closing state, and the flipping range is small, and the operation amount is small; third, when it is particularly necessary, the cover 3 can be fully opened, and the control buttons 9 are fully exposed to allow the operator's special operation.

[0078] The control button 9 is of any type, and may be a mechanical button, a touch button of a touch screen, or both a mechanical button and a touch button.

[0079] In one embodiment, the cover 3 is plate-shaped, and a first connection portion 5 is provided between the cover 3 and the shaft 2, and the first connection portion 5 is bent and connected to the cover 3. Not limited thereto, in other optional embodiments, the cover 3 and the shaft 2 may have other relative positional relationships.

[0080] The fully closed state of the cover 3 is that the cover 3 is horizontally against the base 1. Figure 5 and Figure 6 shown.

[0081] The hovering state of the cover body 3 is to flip upward at a certain angle from the horizontal. Figures 8 to 10 shown.

[0082] The fully opened state of the cover body 3 is that the cover body 3 is flipped upward at a greater angle from the horizontal. Fig.12 shown.

[0083] It is understandable that, depending on the specific application, the angles corresponding to the fully closed state, the hovering state and the fully opened state of the cover body 3 are not limited and should be set according to the specific application requirements of the flip cover structure 100.

[0084] For example, Figure 4 As shown in, in a specific embodiment, the first stage of the rotating shaft 2 is 0 degrees to 30 degrees (excluding 30 degrees), the second stage of the rotating shaft 2 is 30 degrees to 60 degrees (including 30 degrees and 60 degrees), and the third stage of the rotating shaft 2 is 60 degrees to 90 degrees (excluding 60 degrees).

[0085] It should be noted that, depending on the specific usage orientations of the base 1 and the cover 3 , the gravity of the cover 3 , the first connecting portion 5 and the rotating shaft 2 has a certain influence on the automatic closing, hovering and automatic opening of the cover 3 .

[0086] For example, taking the fully closed state of the cover body 3 as an example, with the cover body 3 horizontally against the base 1, in the first stage, the second stage and the third stage, the compression degree of the elastic member 4 and the static friction between the shaft 2 and the base 1 are set, and the influence of the overall gravity of the cover body 3, the first connecting part 5 and the shaft 2 on the torque (gravity torque) generated by the shaft 2 must also be considered.

[0087] In practical applications, the influence of gravity moment in each stage can be reduced by lightweight design of the rotating shaft 2, the first connecting portion 5 and the cover body 3. Thus, the flip cover structure 100 can be applied in more directions.

[0088] In one embodiment, if Figure 4 As shown, in the direction away from the second segment AB ( Figure 4In the clockwise direction in the first section DA, i.e., the Y direction), the distance from each point on the first section DA to the rotation center axis X gradually decreases. The purpose of this design is that the distance from each point on the first section DA to the rotation center axis X gradually decreases, which is equivalent to the first section DA being tilted closer and closer to the rotation center axis X. In this case, the deviation between the force F' applied by the elastic member 4 and the rotation center axis X will be greater, that is, the force arm formed by the force F' relative to the rotation center axis X will also be greater (the degree of compression of the elastic member 4 and the degree of reduction of the force F' caused by the gradual distance of each point on the first section DA from the elastic member 4 will be less than the increase of the force arm), so that the moment M' will gradually increase, and then, it will be easier to make the rotating shaft 2 automatically close.

[0089] Similarly, in the direction away from the second segment AB ( Figure 4 In the counterclockwise direction in the third section BE), the distance from each point on the third section BE to the rotation center axis X gradually decreases. In the third stage, it is easier to make the rotating shaft 2 open automatically.

[0090] In an alternative embodiment, if Figure 4 As shown, the first section DA is a straight section perpendicular to the rotation center axis X. The purpose of this arrangement is, first, to facilitate the processing of the outer peripheral surface of the shaft 2; second, the elastic member 4 applies a force F' on the first section DA to make the shaft 2 automatically recover. When the elastic member 4 acts on F' perpendicular to the first section DA, the force on F' will become perpendicular to the rotation center axis X (see Figure 6 At this time, the cover body 3 can be stably maintained in the fully closed state.

[0091] Similarly, in an optional embodiment, if Figure 4 As shown, the third section BE is a straight line section perpendicular to the rotation center axis X. At this time, the force F2 applied by the elastic member 4 to the rotating shaft 2 vertically passes through the rotation center axis X. This is conducive to the cover body 3 being stably maintained in the fully open state.

[0092] In an optional embodiment, the first segment DA and the third segment BE are mirror-symmetrical about the center line of the second segment AB. This makes the angles corresponding to the first stage and the second stage the same. Of course, depending on the specific application, when the angles corresponding to the first stage and the second stage are different, the first segment DA and the third segment BE do not need to be mirror-symmetrical.

[0093] Next, please refer to Fig.13 As shown, the side of the elastic member 4 facing the rotating shaft 2 forms an abutment line T ( Fig.13 It is a top view, the abutment line T is perpendicular to the paper surface, and the abutment line T is represented by a dot here, and the abutment point is located on the abutment line T.

[0094] Especially when the first section DA and the third section BE are straight sections, the abutment line T can completely abut the first section DA and the third section BE, respectively, thereby further facilitating the cover body 3 to stably remain in the fully closed state and the fully opened state.

[0095] Of course, the cover 3 may be maintained in the fully closed state and the fully open state by other means (or in combination with other means), for example, by a limiting structure (not shown) provided on the base 1 .

[0096] Specific reference Fig.13 As shown, in one embodiment, along the direction of the rotation center axis X, the elastic member 4 includes at least one arched protrusion 41. The top of the arched protrusion 41 is arranged toward the rotating shaft 2. When subjected to pressure, the arched protrusion 41 can be deformed to a certain extent, thereby providing pressure to the rotating shaft 2.

[0097] The surface of the arched protrusion 41 may be a smoothly transitioned arc, such as Fig.13 As shown; it can also be bent in multiple sections, etc.

[0098] like Fig.13 As shown, the elastic member 4 includes two arched protrusions 41, and a second connecting portion 42 is formed between two adjacent arched protrusions 41. The fastener 6 ( Figure 3 The second connecting portion 42 is shown in FIG. 1 , so as to fix the elastic member 4 on the base 1. The fastener 6 can be a screw, a pin, etc.

[0099] Without limitation to this, according to specific needs, the fastener 6 can connect the elastic member 4 and the base 1 at other positions, such as at one end or both ends of the arched protrusion 41, or the fastener 6 can be provided between at least one point of the arched protrusion 41 and the arched protrusion 41.

[0100] In more embodiments, according to different axial lengths of the rotating shaft 2 , the elastic member 4 may be provided with more arched protrusions 41 .

[0101] In other optional embodiments, the side of the elastic member 4 facing the rotating shaft 2 forms an abutment surface parallel to the rotation center axis X, and there are multiple abutment points abutting the rotating shaft 2, all located on the abutment surface, and arranged and connected in a manner parallel to the rotation center axis X.

[0102] In more embodiments, the elastic member 4 may have other configurations, as long as it can provide a force perpendicular to the rotation center axis X to the second section AB.

[0103] The material of the elastic member 4 is not particularly limited. For example, it can be steel or plastic. The material can be selected based on the force required between the elastic member 4 and the rotating shaft 2 and in combination with the manufacturing cost.

[0104] Next, see Figure 3 As shown, mounting holes 20 are formed at both axial ends of the rotating shaft 2. The flip cover structure 100 also includes an optical axis 7 and a bushing 8. The bushing 8 is fixed in the mounting hole 20. The optical axis 7 is arranged in the bushing 8 and remains coaxial and fixed with the rotating shaft 2 (such as interference fit or welding, etc.). In this way, the rotating shaft 2 can be rotatably mounted on the base 1.

[0105] In an optional embodiment, the bushing 8 and the mounting hole 20 may be selectively eliminated, and the optical axis 7 may be directly connected to the axial ends of the rotating shaft 2 in an integral manner or through other connecting parts (not shown).

[0106] The outer diameter of the optical axis 7 is not limited, and can be smaller than the diameter of the second section AB, or larger than or equal to the diameter of the second section AB. It is only necessary to ensure that the cooperation between the optical axis 7 and the base 1 does not interfere with the cooperation between the rotating shaft 2 and the elastic member 4.

[0107] Please see again Figure 2 and Figure 3 As shown, in one embodiment, a receiving groove 10 is formed on the base 1, and each control button 9 is arranged in the receiving groove 10. When the cover 3 is in a fully closed state, as shown in FIG. Figure 2 As shown, the surface of the cover body 3 abuts against the upper end of the receiving groove 10 .

[0108] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
