Description

Technical Field

[0001] The invention relates to the field of intracranial aneurysm interventional surgery instruments, and in particular to a guide wire follower telescopic tube device for intracranial aneurysm interventional surgery. Background Art

[0002] Interventional surgery for intracranial aneurysms is one of the most effective ways to treat cardiovascular diseases because of its low trauma and high precision and controllability. However, during the operation, interventional physicians will be harmed by prolonged exposure to radiation. In addition, in order to reduce radiation, they need to wear heavy lead clothing and stand for a long time. This unergonomic operating posture will accelerate muscle fatigue, central nervous system fatigue, and mental fatigue. These negative factors not only affect the health of doctors, but also seriously affect the decision-making and operational stability of doctors during the operation. The birth of vascular robots can avoid long-term radiation damage to doctors. With the assistance of robots, interventional physicians do not need to wear heavy lead clothing and can remotely operate the machine outdoors or in a remote radiation-free environment.

[0003] However, currently robots are unable to operate guidewires and other instruments at the nearest end of the Y-shaped connector like interventional physicians do. As a result, there is a distance between the Y-shaped connector and guidewires and other instruments. Without tool protection, when the robot pushes guidewires and other instruments, they are prone to arching and bending.

[0004] In addition, since the clamping method of the guide wire clamping head is thread rotation clamping, the guide wire clamping head is movable, and a fixed protective tool is difficult to adapt to usage requirements. Summary of the invention

[0034] According to an embodiment of the present invention, a guide wire follower telescopic tube device for intracranial aneurysm interventional surgery has at least the following beneficial effects: the guide wire passes through the first tube 200 and the second tube 300, and the guide wire is confined in the first tube 200 and the second tube 300 to prevent the guide wire from being arched or bent, and the overall length is adjustable through the mutual movement between the first tube 200 and the second tube 300, which is convenient for installation; the first positioning groove 311 cooperates with the first positioning block 110 to enable the second mounting joint 310 to be installed on the consumable box body 100, and the second mounting joint 310 is installed on the consumable box body 100. 10 is relatively fixed to the consumable box body 100, and the second mounting joint 310, the spring 410, the telescopic rod 420, and the guide wire clamping head 140 are abutted in sequence. When the guide wire clamping head 140 rotates to loosen the guide wire, the guide wire clamping head 140 will be squeezed onto the telescopic rod 420, and the spring 410 will contract. When the guide wire clamping head 140 rotates to clamp the guide wire, the guide wire clamping head 140 will release the contact with the telescopic rod 420, the spring 410 is reset, and the guide wire clamping head 140 is still abutted against the telescopic rod 420, ensuring that the telescopic rod 420 is always connected to the guide wire clamping head 140.

[0035] In some embodiments of the present invention, a plurality of magnetic members 500 are further included, and the plurality of magnetic members 500 are respectively mounted on the first mounting joint 210 and the second mounting joint 310, and the magnetic members 500 are magnetically connected to the consumable box body 100.

[0036] In some embodiments of the present invention, the guide wire clamping head 140 continuously expands from close to the second mounting joint 310 to far away from the second mounting joint 310. It can be understood that the guide wire clamping head 140 is tapered as a whole, and the top of the cone abuts against the telescopic rod 420. The telescopic tube is provided with a tapered groove. The guide wire clamping head 140 cooperates with the tapered groove so that the guide wire clamping head 140 is partially embedded in the telescopic tube, ensuring that the guide wire clamping head 140 can be aligned with the telescopic tube, ensuring that the guide wire can be stably output into the second pipe fitting 300.

The telescopic rod 420 can slide relative to the second mounting joint 310. After the nut 330 is installed on the second mounting joint 310, the telescopic rod 420 can be limited to move in the limiting groove formed by the cooperation of the nut 330 and the second mounting joint 310, so as to prevent the telescopic rod 420 from being separated from the second mounting joint 310.

[0040] In some embodiments of the present invention, an end cap 600 is further included, and the end cap 600 is rotatably connected to the consumable box body 100. The end cap 600 is used to protect the internal structure of the consumable box body 100, and at the same time protect the first tube 200 and the second tube 300 to prevent the first tube 200 and the second tube 300 from being separated from the consumable box body 100.
