Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to an operating table armrest assembly and an operating platform. Background Art

[0002] Common minimally invasive surgical robots are composed of a doctor's console, a patient's operating platform and a display device. The surgeon operates the input device at the doctor's console. In actual use, the doctor will place both hands on the operating table. However, due to the different heights and body lengths of different doctors, the early arm rest plate is a fixed structure and cannot be adjusted to a suitable position according to the specific situation of the user. Prolonged use will affect the operation comfort and accuracy of the doctor.

[0003] In order to adapt to the different height requirements of users, the existing operating tables are provided with a liftable tabletop. For example, Chinese Patent CN207870961U discloses a doctor's console of a surgical robot, which sets a lifting column in the center of the bottom of the console to realize the lifting of the console. However, such a structure makes the pressure of the entire console concentrated on the lifting column, resulting in excessive pressure on the lifting column and its internal driving device, so that the driving device requires a large driving force. At the same time, the elbow support platform for supporting the doctor's arm protrudes outward and is not on the same axis as the lifting column, further increasing the matching pressure between the lifting column and the outer shell, making it easy to generate excessive friction during use, resulting in a high transmission energy consumption rate and easy to generate an angular difference due to wear, affecting the use stability.

[0004] Another example is a lifting assembly, an armrest mechanism and a doctor's main console disclosed in Chinese Patent CN 117122425U. It uses lifting columns arranged on both sides of the bottom of the operating table. It sets a motor and a lead screw on one column for driving, and uses sliders and slide rails to make the first column and the second column on both sides lift synchronously. However, in actual use, only one motor is used for unilateral driving. In actual use, doctors are used to placing both arms on the operating table surface, and it is difficult to ensure uniform force on both columns during operation, which requires too high a bearing capacity for unilateral driving, thereby affecting the synchronous lifting of both columns. Summary of the Utility Model

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and provide an operating table armrest assembly and an operating platform.

[0006] The purpose of the utility model is achieved by the following technical solutions:

[0013] Preferably, the driving motor is a stepping motor.

And, in the description of the solution, with the operator as a reference, the direction close to the operator is the proximal end, and the direction away from the operator is the distal end.

[0031] As Figures 1 to 5 shown, the present utility model discloses an operating table armrest assembly, which includes an operating platform 1 and two lifting columns 2. The two lifting columns 2 are symmetrically and vertically arranged. The operating platform 1 is horizontally mounted on the two lifting columns 2. It is characterized in that each lifting column 2 includes a fixed cylinder 201 and a movable cylinder 202. The movable cylinder 202 is movably embedded in the fixed cylinder 201. A driving module is arranged inside the fixed cylinder 201. The driving module includes a driving motor 3 and a driving component. The top of the movable cylinder 202 is fixedly connected to the operating platform 1, and the bottom of the movable cylinder 202 is fixedly connected to the driving component. The driving motors 3 in the two lifting columns 2 synchronously drive the two movable cylinders 202 to synchronously lift relative to the two fixed cylinders 201, so that the operating platform 1 is horizontally lifted and lowered.

[0032] This solution symmetrically arranges two lifting columns 2, and driving modules are respectively arranged in the two lifting columns 2 to synchronously drive two movable cylinders 202 through the two driving modules, so as to ensure the consistency of the lifting of the two movable cylinders 202, and further ensure the smoothness of the horizontal lifting of the operation platform 1 located at the tops of the two movable cylinders 202. There is no need to set up a connecting component for synchronous movement, which reduces costs and simplifies the internal structure; it also solves the limitation of the limited bearing capacity of a single driving motor, ensuring the stable and rapid horizontal lifting of the operation platform 1. The two driving modules enhance the bearing capacity of the lifting column 2 to adapt to the lifting requirements of operation platforms 1 of different weights.

[0033] Specifically, connection ends 101 are formed at both ends of the operation platform 1, and the bottom of the connection end 101 is fixedly connected to the top of the movable cylinder 202 to improve the movement consistency of the two. The movable cylinder 202 is movably embedded inside the fixed cylinder 201, so that the movable cylinder 202 does not need to contact the inner wall of the fixed cylinder 201 during the lifting process, reducing the wear of the movable main cylinder 202 or the fixed cylinder 201 during the lifting process, and further ensuring the stability of the horizontal lifting of the operation platform 1.

[0034] Furthermore, a connection bracket 4 extending axially is fixedly provided on the inner wall of the fixed cylinder 201, the driving module is arranged on the connection bracket 4, and the driving motor 3 is fixedly provided at the bottom of the connection bracket 4.

[0035] The housing of the movable cylinder 202 is hollow, and a connection sliding cover 2021 extending axially is fixedly connected to the bottom of its housing. The connection sliding cover 2021 slidably covers the connection bracket 4 and is driven by the driving module to move up and down along the connection bracket 4. Such a structural arrangement improves the adaptability between the connection sliding cover 2021 and the driving module, enhances the lifting stability of the connection sliding cover 2021, and makes it not easy to shake.

[0036] Preferably, an induction piece 203 is fixedly provided on one side of the bottom of the connection sliding cover 2021. An upper induction switch 204 and a lower induction switch 205 are arranged on the inner wall of the fixed cylinder 201 on one side of the connection bracket 4. The upper induction switch 204 and the lower induction switch 205 are connected to the operation platform 1. When the induction piece 203 moves to the upper induction switch 204 and the lower induction switch 205, the operation platform 1 controls the driving motor 3 to stop. As Figure 4 and Figure 5As shown, the upper induction switch 204 is used to define the upper limit position of the movement of the movable cylinder 202, and the lower induction switch 205 is used to define the lower limit position of the movement of the movable cylinder 202. The induction sheet 203 and the upper induction switch 204 and the lower induction switch 205 can be any elements that are suitable for being arranged inside the fixed cylinder 201 and can mutually induce, such as photoelectric induction, etc. The operation platform 1 senses the position of the induction sheet 203 through the upper induction switch 204 and the lower induction switch 205, so as to control the start and stop of the drive motor 3 in a timely manner, and accurately control the lifting of the operation platform 1 to avoid unnecessary wear caused by excessive movement.

[0037] In this solution, the drive motor 3 is preferably a stepping motor, and the drive assembly is preferably a trapezoidal lead screw module, which has a self-locking function.

[0038] Specifically, the drive motor 3 is fixedly arranged at the bottom of the connection bracket 4. The drive assembly includes a drive rod 301 and a slider 302. The drive rod 301 passes through the connection bracket 4, and its bottom is in transmission connection with the drive end of the drive motor 3. The slider 302 is screwed on the drive rod 301. The drive motor 3 drives the drive rod 301 to rotate so that the slider 302 slides up and down along the drive rod 301. The outer side wall of the slider 302 is fixedly connected to the inner wall of the connection sliding cover 2021.

[0039] The outer contour of the shell of the fixed cylinder 201 matches the outer contour of the shell of the connection end 101, and a continuous outer surface is formed between the two to increase the adaptability between the fixed cylinder 201 and the connection end 101. In this solution, the illustrated fixed cylinder 201 and the movable cylinder 202 are both square cylinders. In other feasible embodiments, the fixed cylinder 201 and the movable cylinder 202 can be other feasible cylinders, such as cylinders, prisms, etc., which are not limited here.

[0040] Furthermore, between the two connection ends 101 is a tabletop 102 for the user to place the arm for operation. The height of the tabletop 102 is lower than that of the connection end 101 to form a concave structure, which is more ergonomic and improves the use comfort.

[0041] The upper and lower surfaces of the two ends of the tabletop 102 connected to the connection end 101 are both arc surfaces. The arc surface has stronger strength and toughness than the right-angle surface, so as to enhance the compressive resistance of the two ends of the tabletop 102 during the lifting process and the consistency with the connection end 101, so that the connection between the two ends of the tabletop 102 and the connection end 101 is not easy to break.

[0042] A control computer 5 is provided at the center of the tabletop 102. A control button 103 is provided at the top of one of the connection ends 101 to control the control computer 5. In addition, the prior art, which is not the focus of this solution, will not be elaborated here.

[0043] In addition, this solution also discloses an operating platform, including the operating table armrest assembly as described above. The operating platform also includes necessary components such as a host computer. In addition, the prior art, which is not the focus of this solution, will not be elaborated here.

This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0045] The series of detailed descriptions listed above are only specific descriptions of the feasible embodiments of the present invention, and they are not intended to limit the protection scope of the present invention. Any equivalent embodiments or changes made without departing from the technical spirit of the present invention should be included in the protection scope of the present invention.
