Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to a shielding device and a minimally invasive surgical robot. Background Art

[0002] Minimally invasive surgical robots can reduce the physical labor of doctors during surgery while achieving the purpose of precise surgery. As the input control device and user sensing device of the minimally invasive surgical robot, the reliability of the electrical components of the doctor's console is very important. In order to provide a clean power supply to the doctor's console, the external power supply needs to be reliably shielded. The selection of the shielding cover and the structure of the shielding cover have become one of the key technologies.

[0003] For shielding objects on a plane, a metal cover can be used to cover the shielding object as much as possible. However, when the shielded objects are distributed on two or more planes of different heights, that is, the electrical components are located on different planes of the door plate and the panel, the use of an integrated shielding cover for shielding will inevitably result in multiple parallel installation reference surfaces that cannot be uniquely positioned.

[0004] Therefore, how to overcome the above technical defects is a problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0005] The object of the present invention is to provide a shielding device and a minimally invasive surgical robot, which can solve the problem of being unable to uniquely position due to multiple parallel installation reference surfaces and achieve reliable shielding.

[0006] In order to solve the above technical problems, the present invention provides a shielding device, comprising:

[0007] A door panel and a panel arranged on the door panel;

[0008] A large cover box, arranged on the door panel, for covering the electrical components installed on the door panel;

[0009] A small cover box, arranged on the panel, for covering the electrical components installed on the panel;

[0010] The large cover box and the small cover box are detachably connected via fasteners and have wire holes for connecting lines, and the large cover box and the small cover box are respectively clearance-matched with the fasteners.

[0011] Optionally, an incoming line plug is provided on the panel, and terminals and filters are provided on the door panel. The AC power enters the small cover box from the incoming line plug, enters the terminal of the large cover box through the wire hole, and is connected to the incoming line end of the filter. The outgoing line end of the filter is connected to the inside of the electrical box.

[0012] Optionally, the outlet terminal of the filter is located outside the large cover box, and a gasket for sealing is provided at the connection between the filter and the large cover box.

[0013] Optionally, the large cover box includes a shell with a top opening and a cover snapped with the opening.

[0014] Optionally, the large cover box is fixed to the door panel by screws.

[0015] Optionally, the small cover box is fixed to the panel by screws.

[0016] Optionally, the large cover box and the small cover box are fixed by screws.

[0017] Optionally, the first through hole provided on the panel is larger than the first threaded hole of the small cover box;

[0018] The second through hole of the small cover box is larger than the second threaded hole of the large cover box.

[0019] Optionally, the small cover box and the large cover box are both metal cover boxes.

[0020] The present invention also provides a minimally invasive surgical robot, comprising the shielding device as described above.

[0021] The shielding device and minimally invasive surgical robot provided by the present invention adjust the gap between the large cover box and the fastener, as well as the gap between the small cover box and the fastener, so that the large cover box and the door panel fit tightly, and the small cover box and the panel fit tightly, ultimately solving the problem of unique positioning of multiple parallel installation reference surfaces and achieving reliable shielding.

[0034] It should be noted that, for the convenience of description, only the parts related to the relevant application are shown in the drawings. In the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other.

[0035] It should be understood that the "system", "device", "unit" and / or "module" used in this application is a method for distinguishing different components, elements, parts, portions or assemblies at different levels. However, if other words can achieve the same purpose, the word can be replaced by other expressions.

[0036] As shown in this application and claims, unless the context clearly indicates an exception, the words "a", "an", "a kind" and / or "the" do not refer to the singular, but also include the plural. Generally speaking, the terms "include" and "comprise" only indicate the inclusion of clearly identified steps and elements, and these steps and elements do not constitute an exclusive list. The method or device may also include other steps or elements. The elements defined by the sentence "includes a..." do not exclude the existence of other identical elements in the process, method, commodity or device that includes the elements.

[0037] In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0038] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0039] The core of the present invention is to provide a shielding device and a minimally invasive surgical robot, which can solve the problem of being unable to uniquely position due to multiple parallel installation reference surfaces and achieve reliable shielding.

[0040] In order to enable those skilled in the art to better understand the technical solution provided by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0041] Please refer to Figure 1-Figure 8 The present invention provides a shielding device, including a door panel 1, a panel 2, a large cover box 301 and a small cover box 302.

[0042] The panel 2 is arranged on the door panel 1 .

[0043] The large cover box 301 is disposed on the door panel 1 and is used to cover the electrical components installed on the door panel 1 .

[0044] The small cover box 302 is disposed on the panel 2 and is used to cover the electrical components installed on the panel 2 .

[0045] The large cover box 301 and the small cover box 302 are detachably connected by fasteners and have a wire hole 9 for connecting the lines, and the large cover box 301 and the small cover box 302 are respectively clearance-matched with the fasteners.

[0046] It should be noted that the panel 2 and the door panel 1 are connected by a weld, so there are welding clamping errors and parts processing errors between the two surfaces A and C. If the shielding cover is made into a part, the AB surface and the CD surface need to be fitted at the same time during assembly. There must be two positioning references perpendicular to the z direction. If there is a positioning problem, the AB surface and the CD surface cannot be fitted at the same time, and the resulting gap cannot guarantee good electromagnetic shielding.

[0047] By making the shielding cover into two parts, a large cover box 301 and a small cover box 302, adjusting the gap between the large cover box 301 and the fastener, as well as the gap between the small cover box 302 and the fastener, the large cover box 301 and the door panel 1 can fit tightly, and the small cover box 302 and the panel 2 can fit tightly, ultimately solving the problem of unique positioning of multiple parallel installation reference surfaces and achieving reliable shielding.

[0048] In the specific embodiment, the panel 2 is provided with an incoming line plug 8, the door panel 1 is provided with a terminal 10 and a filter 4, the mains electricity enters the small cover box 302 from the incoming line plug 8, passes through the wire hole 9 and enters the terminal 10 in the large cover box 301, and then is connected to the incoming line terminal 7 of the filter 4 ( Figure 4 and Figure 5 The incoming line process is well explained), and the outgoing line terminal 6 of the filter 4 is connected to the inside of the electrical box.

[0049] It can be seen that the mains power enters the shielding cover from the incoming plug 8 and is connected to the incoming terminal 7 of the filter 4 through the terminal 10. The interference signal is filtered out by the filter 4, and the clean power comes out from the outgoing terminal 6 of the filter 4 and is connected to the inside of the electrical box. Through the above structure, the interference signal is shielded inside the shielding cover and outside the electrical box.

[0050] In a preferred embodiment, the outlet terminal 6 of the filter 4 is located outside the large cover box 301 , and a gasket 5 for sealing is provided at the connection between the filter 4 and the large cover box 301 .

[0051] like Figure 5 As shown in the internal wiring diagram, in order to perform maintenance and inspection on the internal junction box, the large cover box 301 includes a shell with a top opening and a cover 303 that is snapped with the opening. The cover 303 of the large cover box 301 can be opened to facilitate internal inspection.

[0052] In a specific embodiment, the large cover box 301 is fixed to the door panel 1 by screws. The small cover box 302 is fixed to the panel 2 by screws. The large cover box 301 and the small cover box 302 are fixed by screws.

[0053] like Figure 7As shown, the aperture of the first through hole 104 opened on the panel 2 is 2u larger than the aperture of the first threaded hole 103 of the small cover box 302. Through the analysis and calculation of the dimension chain, u is reasonably selected so that u is larger than the aperture of the large cover box 301, the small cover box 302, and the door panel 1 in the x direction (such as Figure 4 The cumulative tolerance of the dimensional chain (as shown) can make the E surface of the small cover box close to the F surface of the large cover box.

[0054] like Figure 8 As shown, the aperture of the second through hole 1104 of the small cover box 302 is 2v larger than the aperture of the second threaded hole 1103 of the large cover box 301. By analyzing and calculating the dimension chain, v is reasonably selected so that v is larger than the diameter of the large cover box 301, the small cover box 302, the door panel 1, and the panel 2 in the z direction (such as Figure 4 The cumulative tolerance of the dimensional chain (as shown) can make the B side of the small cover box close to the A side of the panel.

[0055] like Figure 6 , Figure 7 and Figure 8 As shown, during assembly, first, place the D surface of the large cover box 301 close to the C surface of the door panel 1, and fix the large cover box 301 on the door panel 1 with screws; then place the B surface of the small cover box 302 close to the A surface of the panel 2, and the E surface of the small cover box 302 close to the F surface of the large cover box 301, and fix them with screws respectively.

[0056] Preferably, the shielding device includes a small cover box 302, a large cover box 301, a cover 303, a door panel 1, a panel 2, a shell of the filter 4, etc. One or more of the above shielding devices can be made of metal material and have a good shielding effect.
