With the rapid development of medical technology, vascular interventional therapy has become a hot spot in medical treatment today. In interventional therapy, doctors have been able to insert catheters or instruments into almost all blood vessel branches, digestive tract and other specific parts of the human body for the treatment of diseases. Most items of interventional therapy are carried out in blood vessels, and generally only need to open a 3-4mm wound to realize the interventional treatment of small blood vessels.

The routine operation steps of endovascular interventional therapy are: the guide catheter is inserted into the patient's artery through the introducer, and positioned near the arterial ostium of the patient's lesion, then the guide wire is inserted into the guide catheter through the hemostatic valve, and then the guide wire is controlled in the blood vessel. Move until the guidewire reaches the lesion. This process is mainly the advancing action of the guide wire and the catheter inserted into the blood vessel and the twisting action of finding the direction angle. In order to achieve different blood vessels and branch vessels, the general guide wire or micro guide wire head has a certain shape of bending angle and a certain shape of the elbow. The doctor chooses the appropriate elbow for different vascular systems or branch vessel shapes. At the bifurcation of the vascular pipeline, rotate the guide wire or micro-guide wire, use the different directions when the elbow rotates to guide its next step, and finally the guide wire or micro-guide wire enters the branch blood vessel.

The status information of the operating device or the execution end, for example, whether there is a false touch, or whether the equipment at the execution end is overloaded or whether the maximum stroke is reached, etc. In addition, it is also preferable to set a vibration device or sound in the accommodation cavity of the curved surface support structure 21 device, so as to be able to play a better prompting role through sound prompts or vibration prompts. For example, when the flexible touch film is touched, the vibration device vibrates to remind the operator that the flexible touch film has been touched. If the operator feels the vibration If the touch is stopped immediately, it can be judged as a false touch. If the operator’s finger is still placed on the flexible touch film for 3 seconds, it is judged as a non-mistouch. touch operation.

More specifically, as an optional embodiment of the curved three-dimensional touch operating device of the present invention, one end of the curved support structure 21 connected to the C-shaped support structure may be provided with a cover structure, and the cover structure may preferably be set as The detachable cover structure can facilitate the overall replacement and installation of the curved support structure 21 and the touch module 1. The detachable cover structure can be connected with the curved support structure 21 by bolts. The sliding friction during sliding is usually small, so it will not affect the reliability of the screw connection, and therefore, in order to further facilitate the installation and disassembly of the detachable cover structure, the detachable cover structure and the curved support structure 21 can be It is preferably arranged to be clamped by a locking structure, so as to improve the convenience of disassembly and assembly of the detachable cover structure while ensuring the connection strength; wherein the curved support structure 21 can be a plastic part, thereby reducing the friction of the curved three-dimensional touch operation device. weight, and can save manufacturing costs.

More specifically, as an optional embodiment of the curved three-dimensional touch operating device of the present invention, the control module 3 includes a data processing unit and a program control unit, and the data processing unit can receive the sensing signal of the touch module 1 (the sensing signal includes a speed signals, position signals, and acceleration signals), and analyze the induction signals to obtain the sliding direction, sliding distance, and sliding speed of the operator's finger on the touch module 1. The program control unit is preset with a control program and Algorithm strategy, and can control the operation terminal according to the analysis results of the induction signal. Specifically, when the execution end is a solid device (such as a robot arm or a machining center), the actuator in the solid device should have at least one directional translational degree of freedom and at least one axial rotational degree of freedom, and the rotational degree of freedom The axial direction of the rotation axis needs to be consistent with the translational direction of one of the translational degrees of freedom, so that the movement amount and the corresponding rotation amount in the translational direction of the translational degree of freedom can be controlled according to the sliding direction and sliding distance. When the actuator When it is a virtual model or an animation (such as a virtual three-dimensional data model or a plane data model controlled by software such as a game engine or an image processing engine), the execution end can be controlled by a program according to the sliding direction and sliding distance of the finger on the touch module 1. The amount of movement, rotation, or other posture changes of a virtual model or animation; for example, when a curved three-dimensional touch operating device is applied to manipulate surgical instruments, the corresponding surgical instrument drive unit (that is, the physical device) has translational freedom in the X-axis direction degree and the rotational degree of freedom of the axial rotation around the X-axis, when the operator's finger moves forward on the touch module 1 (corresponding to the movement of the surgical instrument drive unit to the positive direction of the X-axis), it rotates clockwise When rotating (corresponding to the clockwise rotation of the surgical instrument drive unit around the X-axis), the surgical instrument drive unit can control the corresponding surgical instrument to rotate and move forward accordingly, so that there is no need to decompose and distribute the rotation and movement of the movement trajectory. The control speed is greatly improved, and the operation difficulty of the operator is reduced, and the proportional relationship between the amount of movement or rotation of the surgical instrument controlled by the surgical instrument drive unit and the actual movement or rotation of the operator's fingertip on the touch module 1 can be Set according to the actual situation, for example, when operating the micro guide wire, the ratio between the movement of the surgical instrument controlled by the surgical instrument drive unit and the actual movement of the operator's fingertip on the touch module 1 can be adjusted to 1:20; in addition , endovascular intervention generally requires multiple surgical instruments to complete, such as guide wires, micro guide wires, catheters and micro catheters, so the surgical instrument drive unit should also be equipped with a surgical instrument selection unit to be able to select different surgical instruments. Drive; it can be understood that the above-mentioned control operation of the surgical instrument can ignore the acceleration of the surgical instrument when it moves, so there is no need to identify and analyze the acceleration signal, but the curved surface three-dimensional touch operating device is applied to manipulation in simulation training (such as virtual games) When the submarine is controlled in the center), the corresponding virtual engine can identify the acceleration signal as needed to control the acceleration speed of the submarine.
