Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an electromagnetic shielding cabinet. Background Art

[0002] Minimally invasive surgery refers to a surgical method that uses modern medical instruments such as laparoscopes and thoracoscopes and related equipment to perform surgery inside the human body cavity. Compared with traditional surgical methods, minimally invasive surgery has the advantages of less trauma, less pain, and faster recovery. However, due to the limitation of the incision size, the difficulty of minimally invasive instruments in minimally invasive surgery has greatly increased, which has become a key factor restricting the development of minimally invasive surgical technology. With the development of robotic technology, a new technology in the field of minimally invasive medicine that can overcome shortcomings and inherit advantages has emerged - minimally invasive surgical robot technology.

[0003] Common minimally invasive surgical robots consist of a doctor's console, a patient-side trolley, and a display device. The surgeon operates the input device on the doctor's console and transmits the input to the patient's surgical platform connected to the remotely operated surgical instrument. When the robot is performing electromagnetic radiation detection on the entire machine, the robot needs to be turned on and working. In the working state, the endoscope and its light source equipment also need to be turned on. However, these devices will generate large electromagnetic radiation, which has a great impact on the robot's detection, so they need to be electromagnetically shielded.

However, general shielding cabinets have the problem of inadequate shielding for endoscopes and display devices, resulting in a high probability of electromagnetic leakage, which affects the detection results.

[0046] The electromagnetic shielding cabinet provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in combination with the accompanying drawings.

[0047] like Figures 1 to 3 As shown, an embodiment of the present application provides an electromagnetic shielding cabinet, including a shielding cabinet body 100, a shielding cavity 110 arranged in the shielding cabinet body 100 and open on one side, a heat dissipation unit for dissipating heat inside the shielding cavity 110, and a first cabinet door 130 hingedly arranged on the shielding cabinet body 100 and used for opening and closing the shielding cavity 110.

[0048] The shielding cavity 110 can be used to install a functional unit, which at least includes an endoscope and its light source device and a display device.

[0049] In an embodiment of the present application, an electromagnetic shielding cabinet as described above is used, which is adapted to the endoscope and its light source equipment and display equipment of the surgical robot. When the functional unit is installed in the shielding cavity 110 and is in the power-on state, closing the shielding cavity 110 by the first cabinet door 130 can effectively shield the electromagnetic and prevent electromagnetic leakage, making the electromagnetic radiation detection result of the whole machine more accurate. At the same time, the endoscope and its light source equipment and display equipment are integrated through centralized management to facilitate heat dissipation and improve its working stability.

[0050] In a preferred embodiment, Figure 1 , Figure 2 As shown, a power supply slot 111 for installing the power module 400 is provided in the shielding cavity 110 .

[0051] It is understandable that the power module 400 can be used to supply energy to the functional unit. The power module 400 is built into the shielding cavity 110. On the one hand, it is convenient for coupling with the functional unit. On the other hand, it can dissipate heat through the heat dissipation unit, thereby improving the overall stability of the system.

[0052] In a preferred embodiment, Figure 1 , Figure 2 As shown, the shielding cabinet 100 is provided with a first installation slot 112 for installing the first functional module 500 , a second installation slot 113 for installing the second functional module 600 , and a third installation slot 114 for installing the third functional module 700 .

[0053] It can be understood that the first functional module 500, the second functional module 600, and the third functional module 700 can be respectively set as one of an endoscope and its light source device and display device.

[0054] In a preferred embodiment, Figure 1 , Figure 2 As shown, the energy supply groove 111, the first installation groove 112, the second installation groove 113, and the third installation groove 114 are arranged along the vertical direction.

[0055] The energy supply slot 111 is located on the side of the first installation slot 112 , the second installation slot 113 , and the third installation slot 114 close to the ground.

[0056] In a preferred embodiment, Figure 3 As shown, a first clearance groove 170 penetrating the corresponding side end surface of the shielding cabinet 100 is provided on the inner wall of the shielding cavity 110 away from the first cabinet door 130 at a position corresponding to the first installation groove 112 .

[0057] The control module (switch, control button, interface, etc.) of the first functional module 500 can be plugged into the first clearance groove 170 and extend to the outside of the shielding cabinet 100 through the first clearance groove 170 .

[0058] In a preferred embodiment, Figure 3 As shown, a second clearance groove 180 penetrating the corresponding side end surface of the shielding cabinet 100 is provided on the inner wall of the shielding cavity 110 away from the first cabinet door 130 at a position corresponding to the second installation groove 113 .

[0059] The control module (switch, control button, interface, etc.) of the second functional module 600 can be plugged into the second clearance groove 180 and extend to the outside of the shielding cabinet 100 through the second clearance groove 180 .

[0060] In a preferred embodiment, Figure 3As shown, a third clearance groove 190 penetrating the corresponding side end surface of the shielding cabinet 100 is provided at a position corresponding to the third installation groove 114 on the inner wall of the shielding cavity 110 away from the first cabinet door 130 .

[0061] The control module (switch, control button, interface, etc.) of the third functional module 700 can be plugged into the third clearance slot 190 and extend to the outside of the shielding cabinet 100 through the third clearance slot 190 .

[0062] In an embodiment of the present application, an electromagnetic shielding cabinet as described above is adopted, and switches, control buttons, and interface protrusion windows of functional units are set on the inner wall of the shielding cavity 110 to facilitate the operator to control the functional units and connect the functional units with the robot, thereby improving the robot's electromagnetic radiation detection efficiency.

[0063] In a preferred embodiment, Figures 1 to 3 As shown, the heat dissipation unit includes a plurality of ventilation windows 120 penetrating between the inner wall of the shielding cavity 110 and the corresponding side end surface of the shielding cabinet 100, and a plurality of ventilation fans 200 fixedly arranged on the inner wall of the shielding cavity 110 and corresponding to the positions of the plurality of ventilation windows 120.

[0064] Among them, a plurality of ventilation windows 120 and ventilation fans 200 are respectively located at corresponding positions of the power module 400 , the first functional module 500 , the second functional module 600 , and the third functional module 700 .

[0065] It is understandable that the ventilation fan 200 cooperates with the ventilation window 120 to achieve air circulation at the power module 400 and the functional unit inside the shielding cavity 110, thereby ensuring the heat dissipation of the power module 400 and the functional unit and improving their stability in the working state.

[0066] In a preferred embodiment, Figures 1 to 3 As shown, the heat dissipation unit includes two groups of ventilation windows 120 and two groups of ventilation fans 200 which are symmetrically arranged with respect to the opening direction of the shielding cavity 110 .

[0067] Each group of ventilation windows 120 includes a plurality of ventilation windows 120 that penetrate between the lateral side wall at the opening of the shielding cavity 110 and the corresponding side end surface of the shielding cabinet 100, and each group of ventilation fans 200 includes a plurality of ventilation fans 200 that are fixedly arranged on the lateral side wall at the opening of the shielding cavity 110 and correspond to the positions of the plurality of ventilation windows 120.

[0068] Among them, a plurality of ventilation windows 120 and ventilation fans 200 are respectively located at corresponding positions of the power module 400 , the first functional module 500 , the second functional module 600 , and the third functional module 700 .

[0069] In a preferred embodiment, Figure 2As shown, a support frame 800 is fixedly provided on the inner wall of the shielding cavity 110 , and a first installation groove 112 , a second installation groove 113 , and a third installation groove 114 for installing the functional unit are provided on the support frame 800 .

[0070] The energy supply groove 111 , the first installation groove 112 , the second installation groove 113 , and the third installation groove 114 are connected in the longitudinal direction, and the first installation groove 112 , the second installation groove 113 , and the third installation groove 114 are connected in the transverse direction with the shielding cavity 110 .

[0071] In a preferred embodiment, the ventilation fan 200 on one of the lateral side walls at the opening of the shielding cavity 110 is configured as a suction fan, and the ventilation fan 200 on the other lateral side wall is configured as an exhaust fan.

[0072] It can be understood that the suction fan is used to transport the air outside the shielding cabinet 100 into the shielding cavity 110, and the exhaust fan is used to discharge the air inside the shielding cavity 110 to the outside of the shielding cabinet 100. Through the suction and exhaust arrangement of the ventilation fans 200 on the two lateral side walls of the shielding cavity 110, a lateral one-sided air circulation can be formed inside the shielding cavity 110, thereby achieving heat dissipation for the power module 400 and the functional units in the shielding cavity 110.

[0073] In a preferred embodiment, the ventilation fan 200 located at a position corresponding to the third functional module 700 is configured as a suction fan, and the ventilation fan 200 located at a position corresponding to the power module 400 is configured as an exhaust fan.

[0074] It is understandable that the density of hot air is less than that of cold air, so temperature stratification will occur in the air inside the shielding cavity 110. After the ventilation fan 200 at the corresponding position of the third functional module 700 is set as an suction fan, the first mounting groove 112, the second mounting groove 113, and the third mounting groove 114 on the support frame 800 are connected to the energy supply groove 111 in the longitudinal direction, so that the hot air accumulated at the position of the third functional module 700 can be transported to the side of the power module 400, thereby achieving temperature balance of the air inside the shielding cavity 110 and ensuring the stability of the working environment of each electronic component.

[0075] It can be understood that the ventilation fan 200 at the corresponding position of the first functional module 500 and the second functional module 600 can be set as a suction fan or an exhaust fan. In this case, an air flow field with air flowing in from top to bottom and out from bottom can be generated in the shielding cavity 110; if the ventilation fan 200 at the corresponding position of the first functional module 500 is set as an exhaust fan and the ventilation fan 200 at the corresponding position of the second functional module 600 is set as a suction fan, a local air convection field can be generated in the shielding cavity 110, thereby further improving the heat dissipation effect.

[0076] In a preferred embodiment, Figures 1 to 3 As shown, a receiving cavity 150 with an opening on one side is further provided in the shielding cabinet 100 , and a second cabinet door 160 for opening and closing the receiving cavity 150 is hingedly provided on the shielding cabinet 100 .

[0077] The accommodating cavity 150 is located on a side of the shielding cavity 110 close to the ground.

[0078] It is understandable that other components can be installed in the accommodating cavity 150 or it can be left empty. The accommodating cavity 150 can increase the height of the shielding cavity 110 from the ground, so that the shielding cavity 110 reaches a height that is easy for human hands to operate, without bending over during operation, thereby improving the user experience of the shielding cabinet.

[0079] In a preferred embodiment, Figures 1 to 3 As shown, four universal wheels 300 are fixedly provided at the bottom of the shielding cabinet 100 , and the four universal wheels 300 are respectively located at four corners of the bottom of the shielding cabinet 100 .

[0080] It can be understood that the universal wheel 300 can realize the overall movement of the shielding cabinet 100, thereby improving the practicality of the shielding cabinet.

[0081] In a preferred embodiment, a support frame is fixedly provided at the bottom of the shielding cabinet 100 , and the universal wheel 300 is fixedly arranged at the bottom of the support frame to realize the movement of the shielding cabinet 100 .

[0082] It is understandable that the height of the shielding cavity 110 from the ground can also be increased by the support frame.

[0083] In a preferred embodiment, Figures 1 to 3 As shown, push handles 140 are fixedly disposed on two lateral outer end surfaces of the shielding cabinet 100 in the opening direction of the shielding cavity 110 .

[0084] The push handles 140 on the two transverse outer end surfaces of the shielding cabinet 100 are symmetrically arranged.

[0085] It is understandable that the staff can push and pull the shielding cabinet 100 through the push handle 140 to facilitate the overall movement of the shielding cabinet.

[0086] In a preferred embodiment, a conductive foam surrounding the opening of the shielding cavity 110 and capable of abutting against the first cabinet door 130 is fixedly provided on the end face of the shielding cabinet 100 close to the first cabinet door 130, and / or a conductive foam surrounding the opening of the shielding cavity 110 and capable of abutting against the corresponding side end face of the shielding cabinet 100 is fixedly provided on the end face of the first cabinet door 130 close to the shielding cabinet 100.

[0087] It can be understood that when the first cabinet door 130 is in a closed state, the conductive foam can improve its sealing performance to the shielding cavity 110, thereby further reducing the electromagnetic leakage.

[0088] In a preferred embodiment, a conductive foam surrounding the opening of the accommodating cavity 150 and capable of abutting against the second cabinet door 160 is fixedly provided on the end face of the shielding cabinet 100 close to the second cabinet door 160, and / or a conductive foam surrounding the opening of the accommodating cavity 150 and capable of abutting against the corresponding side end face of the shielding cabinet 100 is fixedly provided on the end face of the second cabinet door 160 close to the shielding cabinet 100.
