摘要 |
A system, device and method for insertion of a penetrating member into tissue is disclosed, which may be handheld and automated. A detector obtains data regarding subdermal locations of tissue structures, including cavities such as blood vessels. A processor calculates the distance between a preselected target point below the tissue surface, such as within a blood vessel, and the tissue surface, and adjustment data for vertical, angular and extension adjustment of the penetrating member. Vertical, angular and extension actuators carry out the adjustments in real-time as calculated and directed by the processor. Changes in the location of the target point result in automatic recalculation and adjustment by the processor and various actuators. A vibrational actuator induces vibration to the penetrating member during insertion, overcome tissue deformation and vein rolling. A guidewire may be inserted through or by the device, for dilator and catheter insertion once the penetrating member is removed. |
