The invention relates to the field of medical devices, and more specifically to a motion system for a vascular intervention navigation surgery system.
Before performing vascular intervention surgery, the surgical robot needs to be installed on the operating bed. During the vascular intervention surgery process, the vascular intervention surgery is performed by controlling the vascular intervention navigation surgery system and its motion system.
At present, the vascular intervention navigation surgery system is able to control the forward and backward movement of the guidewire, as well as the forward and backward movement of the balloon catheter, stent catheter, and guide catheter, etc., as described in the Chinese invention patent submitted on Nov. 5, 2021, with publication number CN 113598947B and invention name “Vascular Interventional Navigation Surgery system”, which is integrated into this application by reference in its entirety. The vascular intervention navigation surgery system is a highly safe robot system that assists doctors in performing vascular intervention surgery, which can avoid serious consequences caused by physiological tremors and misoperation by the doctors during surgery, and can protect the doctors from X-ray radiation. During the surgical process, it may be possible that the doctors may be off-site with the patient and perform the surgery by controlling the vascular intervention navigation surgery system through remote operation. When the guidewire moves in the blood vessel, it will come into contact with the vessel wall and face resistance. Mechanized operation makes it difficult for the doctors to sense the resistance of the guidewire during its movement in the blood vessel. This increases the risk of puncturing the blood vessel during vascular intervention surgery. How to provide more degrees of freedom of motion for vascular intervention navigation surgery systems, effectively detect the resistance of guidewires in the blood vessel to avoid puncturing the blood vessel and provide other functions, so as to carry out more complex vascular intervention surgeries has not been well solved.

The pressure sensor is fixed on the connecting base, and the connecting base is fixed on the sun wheel of the guidewire control module.

The top of the guidewire is just in contact with the contact surface of the pressure sensor. The length range of the resistance detection sleeve is 1-100 millimeters.
Alternatively, the working guidewire and resistance detection guidewire can be fixed with a guidewire fixing clip. The structure of the guidewire fixing clip is two clips connected at the tail, with the upper clip fixing the working guidewire and the lower clip fixing the resistance detection guidewire.
On the outer ring of the pressure sensor, an electric induction magnetic coil is installed. After being energized, the magnetic coil generates magnetism and attracts the resistance detection guidewire to fix the tube. When the pressure sensor moves forward and backward, it will move forward and backward together with the resistance detection guidewire and fixed tube.
The remote microcomputer control end has a force reproduction system main end. When the pressure sensor senses the resistance value, the force reproduction system main end needs to reproduce an equivalent simulated force. The doctor pushes the simulated guidewire of the force reproduction system main end outside the operating room to determine the working guidewire's forward and backward movement in the real blood vessel. The force reproduction system main end consists of a simulated guidewire, a wheel group, a push rod, and a pressure sensor. The wheel group consists of two independent wheels, with the wheel surfaces in contact with each other. The simulated guidewire passes between the two wheels, and the wheels on both sides compress the simulated guidewire. The extrusion force is the resistance of the simulated guidewire to move forward and backward. The forward and backward movement of the push rod can adjust the distance between two wheels. When the push rod is pushed forward, the gap between the two wheels decreases and the friction force increases. When the push rod is pushed backward, the gap between the two wheels increases and the friction force decreases. One of the wheels is equipped with a pressure sensor on the wheel surface. When the two wheels come into contact, the pressure sensor senses the pressure and displays the pressure value.
When the guidewire module advances, the connecting base fixed on the sun wheel pushes the pressure sensor, the resistance detection guidewire, and the guidewire series connector forward together. At this point, the reading on the pressure sensor is the thrust of the working guidewire to move forward.
When the front end of the working guidewire is obstructed from moving forward, and the resistance to it increases, the guidewire serial connector transfers the resistance to the pressure sensor through the resistance detection guidewire. The reading on the pressure sensor is the thrust of the working guidewire to move forward and the resistance to the working guidewire.
At the initial stage of the force reproduction system, there is no pressure between the wheels of the wheel group. When the simulated guidewire is pushed, it drives the wheel group to rotate, and the generated signal is transmitted to the main control system. The main control system sends instructions to the sun wheel group to move forward or backward, thereby driving the guidewire to move forward or backward.
The simulated guidewire diameter used at the force reproduction system main end is 0.35 millimeters. After passing through the wheel group, the guidewire is placed on the guidewire tray, which has a guidewire groove to connect the simulated guidewire head and tail and repeat the push. The guidewire tray is circular, can also be round or arc-shaped.
There is a gap on the guidewire tray for the surgeon to pinch, push, pull, or twist the simulated guidewire with their fingers. The length of the gap is 1-20 centimeters, preferably 3-6 centimeters.

When the operator feels the resistance of the simulated guidewire 32, they rely on their own experience to determine whether to continue operating the sun wheel 23 to control the guidewire to move forward or rotate. The rear end of wheel group 31 is connected to a motor, which controls the pressure between the wheels of the wheel group 31 through the rotation of the motor, that is, controls the resistance of the simulated guidewire 32 between the wheels of the wheel group 31. In another preferred example, when the motor rotates clockwise or counterclockwise, the pressure between the wheels of the wheel group 31 will increase or decrease, and the resistance of the simulated guidewire 32 between the wheels of the wheel group 31 will increase or decrease.
The force reproduction system main end 30 also includes a simulated pressure sensor and a main end control system. The simulated pressure sensor is configured to sense the operator's thrust on the simulated guidewire 32, in order to apply the thrust to the guidewire. When the operator pushes the simulated guidewire 32 against the resistance of the wheel group 31, the motion of the simulated guidewire 32 drives the rotation of the wheel group 31. Based on the rotation of the wheel group 31 detected by the simulated pressure sensor, it controls the forward or backward movement of the sun wheel 23, thereby driving the forward or backward movement of the guidewire. The conversion from the rotational motion of wheel group 31 to the forward or backward rotation angle of sun wheel group 23 to the linear distance is processed by the main end control system.
The simulated guidewire 32 is supported by guidewire tray 33. The simulated guidewire 32 is connected end-to-end and is cyclically pushed. The guidewire tray 33 can be, but is not limited to, circular, round, or arc-shaped. The guidewire tray 33 has a guidewire groove 34, and the guidewire is embedded in the guidewire groove 34; The guidewire tray 33 is equipped with a guidewire bridge 35. At the guidewire bridge 35, the simulated guidewire 32 separates from the guidewire groove 34, and the operator grasps and pushes the simulated guidewire 32 at the guidewire bridge 35. The length of the guidewire bridge 35 is 1-20 centimeters; Preferred 3-6 centimeters. The diameter of the simulated guidewire 32 is 0.35 millimeters.
The force reproduction system can combine the mechanized vascular intervention navigation surgery system with the experience of clinical doctors. When facing blood vessels with high resistance to pass, it can more effectively operate the guidewire movement and avoid damage to the patient's blood vessels, providing surgical safety.
In addition, the experience values operated by the clinical doctors mentioned above can be numbered and classified, stored in memory for easy recall in the next similar situation, without requiring the clinical doctors to manually operate again.
