Description

Technical Field

[0001] This invention relates to the field of myocardial minimally invasive rotary cutter control. More specifically, this invention relates to a low-reflection remote control system for a myocardial minimally invasive rotary cutter. Background Technology

[0002] When conducting electromagnetic compatibility (EMC) tests on the radiated emission and radiated immunity of the minimally invasive myocardial rotary scalpel, the scalpel must be in normal working condition. This requires the operator to press different operation buttons to perform different procedures. The radiated emission and radiated immunity tests are conducted in an anechoic chamber. If the operator enters the chamber and directly performs unlocking, insertion, retraction, needle insertion, and needle retraction operations on the scalpel, it will affect the test results. Furthermore, the radiated electromagnetic field can pose a radiation hazard to the human body. Therefore, the operator must stay away from the scalpel and operate its buttons only during the radiated emission and radiated immunity EMC tests. Summary of the Invention

[0003] The purpose of this invention is to provide a low-reflection remote control system for a minimally invasive myocardial rotary cutter. Through this remote control system, test personnel can operate the minimally invasive myocardial rotary cutter remotely, thereby avoiding radiation hazards to test personnel during radiation emission and electromagnetic compatibility tests.

[0020] like Figures 1-2 As shown, an embodiment of the present invention provides a low-reflection remote control system for a minimally invasive myocardial rotary cutter, including a controller 1, a command input module 2, an air source 3, a pneumatic control mechanism, and five pneumatic buttons 4. The pneumatic control mechanism has an air inlet and five air outlets, one-to-one with the number of pneumatic buttons 4. The five pneumatic buttons 4 correspond to the unlock button, advance button, retraction button, needle advance button, and needle retraction button of the minimally invasive myocardial rotary cutter, respectively. The air inlet of the pneumatic control mechanism is connected to the air source 3, and the multiple air outlets of the pneumatic control mechanism are respectively connected to the air inlets of the corresponding pneumatic buttons 4. The command input module 2 and the pneumatic control mechanism are electrically connected to the controller 1. The command input module 2 is a display screen. The command input module 2 is used to send a command to the controller 1 to control the pressing or releasing of any of the pneumatic buttons 4. The controller 1 controls the pneumatic control mechanism to inflate or deflate any of the pneumatic buttons 4, so that the pneumatic buttons 4 are pressed or released.

[0021] In this embodiment, the air inlet of the pneumatic control mechanism is connected to the air source 3 through a long pipe, and then the pneumatic control mechanism is remotely controlled by the controller 1. This enables remote control of the five pneumatic buttons 4, thereby controlling the unlock button, advance button, retraction button, needle advance button, and needle retraction button of the myocardial micro-invasive rotary cutter. This allows the test personnel to operate the myocardial micro-invasive rotary cutter remotely, thus avoiding radiation hazards to the test personnel during the radiation emission and radiation immunity electromagnetic compatibility test.

[0022] Specifically, the staff sends a command to the controller 1 through the command input module 2 to control any pneumatic button 4 to press or release. The controller 1 then controls the pneumatic control mechanism to inflate or deflate the corresponding pneumatic button 4, causing the pneumatic button 4 to perform the pressing or releasing operation. In one embodiment, the pneumatic control mechanism includes a fixing mechanism and a plurality of air supply control units, which are equal in number and correspond one-to-one with the number of pneumatic buttons 4. Each air supply control unit has an air inlet and an air outlet, and its air inlet is connected to the air source 3. Each air supply control unit is fixed on the fixing mechanism. The air supply control unit includes an air supply pipe 5, a first solenoid valve 6, and a second solenoid valve 7. The air inlet of the pneumatic button 4 is connected to the air outlet of the air source 3 through the air supply pipe 5. The first solenoid valve 6 is disposed on the air supply pipe 5. An exhaust pipe is connected to the portion of the air supply pipe 5 located between the first solenoid valve 6 and the pneumatic button 4. The exhaust pipe is connected to the corresponding air supply pipe 5 through a tee. The second solenoid valve 7 is disposed on the exhaust pipe. The first solenoid valve 6 and the second solenoid valve 7 are electrically connected to the controller 1, respectively.

[0023] In this embodiment, as shown in the appendix Figure 1 As shown, at least one relay can be provided, which is electrically connected to both the power supply and the controller 1. The first solenoid valve 6 and the second solenoid valve 7 are electrically connected to either relay. The controller 1 controls whether the relay energizes the first solenoid valve 6 or the second solenoid valve 7, thereby controlling the opening and closing of the first solenoid valve 6 and the second solenoid valve 7. As one embodiment, see attached... Figure 2 As shown, controller 1 can be composed of a control circuit and two relays. The first relay is electrically connected to the corresponding power supply and the first solenoid valve 6, and the second relay is electrically connected to the corresponding power supply and the second solenoid valve 7. Thus, the control circuit and the first and second relays can control whether the power supply energizes the first solenoid valve 6 and the second solenoid valve 7, thereby controlling the opening and closing of the first solenoid valve 6 and the second solenoid valve 7. Specifically, as shown... Figure 2 As shown, when the gas supply control mechanism has only a single pneumatic button 4, its working process is as follows:

[0024] 1) The control circuit sends an inflation control pulse signal to the first relay according to the pressing time parameter of the pneumatic button 4, which turns on the control power of the first solenoid valve 6. At this time, the second solenoid valve 7 is closed. The first solenoid valve 6 opens the air source 3 to inflate the pneumatic button 4. The power output end of the pneumatic button 4 extends outward to perform the pressing operation. After inflating for a certain period of time, the first solenoid valve 6 is closed to cut off the air source 3, for example, 10ms, and the button is kept in the pressed state.

[0025] 2) Then the control circuit sends a venting control pulse signal to the second relay to turn on the power of the second solenoid valve 75. The air in the pneumatic button 4 is released through the second solenoid valve 7. The power output end of the pneumatic button 4 retracts inward to end the pressing operation. After the button device vents air for a certain period of time, such as 5ms, the solenoid valve is closed to keep the button in the released state.

[0026] 3) Repeat the above cycle according to parameters such as button operation sequence, cycle and pressing time.

[0027] Preferably, in the low-reflection remote control system for a minimally invasive myocardial rotary cutter, the fixing mechanism is a hollow housing 8. The lower end of the housing 8 is provided with a plurality of mounting holes 9, which are equal in number and correspond one-to-one with the number of pneumatic buttons 4. The pneumatic buttons 4 can be set in the corresponding mounting holes 9, and their button ends are located at their lower ends and extend downward to the outside of the housing 8. The air supply pipe 5 passes through the upper end of the housing 8 and is connected to the air inlet of the corresponding pneumatic button 4.

[0028] In this embodiment, such as Figure 3 As shown, five pneumatic buttons 4 are fixed on the fixing mechanism at this time. The five pneumatic buttons 4 correspond to the unlock button, advance button, retraction button, needle advance button and needle retraction button of the myocardial minimally invasive rotary cutter, respectively. The pneumatic control mechanism is remotely controlled by the controller 1 to realize the remote control of the five pneumatic buttons 4, thereby controlling the unlock button, advance button, retraction button, needle advance button and needle retraction button of the myocardial minimally invasive rotary cutter.

[0029] Preferably, in the low-reflection remote control system for a minimally invasive myocardial rotary cutter, the outer wall of the housing 8 is provided with a wave-absorbing layer.

[0030] In this embodiment, an absorbing layer made of absorbing material is provided on the outer wall of the housing 8 to prevent the housing 8 from causing unnecessary disturbances to the electromagnetic environment.

[0031] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and embodiments shown and described herein.
