Puncture device with movable inner tube and locking mechanism
A recently filed patent (Publication Number: US20230310030A1) describes a puncture device and system for medical procedures involving the insertion of a guide wire into a patient's body. The device includes an elongate sheath, a needle tube, a needle slider, an inner tube, a tube slider, and a locking member. The needle tube and inner tube are movable in a longitudinal axis direction, and the locking member can lock the needle slider relative to the tube slider in two different states.
In the first state, the distal end of the inner tube is positioned inside the needle tube, while in the second state, the distal end of the inner tube protrudes out from the needle tube. The locking member consists of a first member and a second member, with the first member locking the needle slider relative to the tube slider in the first state, and the second member locking them in the second state. The needle slider includes a nail, and the first and second members have concave portions that engage with the nail.
The patent also describes a method for using the guide wire with the puncture device. The method involves forming holes in a body using the needle tube, disposing the tip of the needle tube into a second lumen, locking the needle tube relative to the inner tube, injecting a contrast medium into the inner tube, unlocking the locked state, protruding the inner tube from the needle tube, inserting the guide wire into the second lumen, and leaving the guide wire in place by removing the needle tube and inner tube.
The puncture system can also include an injection device for injecting a contrast medium into the inner tube, which can be attached to the tube slider. The method for using the guide wire can involve locking the needle tube relative to the inner tube by locking the tube slider and needle slider in a state where the tip of the inner tube is distal to the tip of the needle tube. Additionally, the method can include moving the tip of the inner tube to a proximal end side relative to the tip of the needle tube by unlocking the needle tube relative to the inner tube and moving the tube slider to a proximal end side relative to the needle slider.
Overall, this patent describes a puncture device and system that allows for precise control and manipulation of the guide wire during medical procedures, improving the accuracy and safety of these procedures.
