Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of interventional surgery tools, in particular to a guide wire guide tube for interventional surgery. Background Art
[0002] In interventional surgery, guidewires are widely used as core instruments for intravascular operations. Existing guidewires are usually designed to be 1.5 meters long and made of flexible materials to adapt to complex vascular pathways. However, due to the short intervention window in the human arm, a longer portion of the guidewire needs to be left outside the body.
[0003] In current clinical operations, medical staff need to wear sterile gloves to manually support the extracorporeal guidewire segment. However, this method does not provide sufficient sterility protection for the guidewire. Particles or microorganisms are easily left on the surface of the gloves. Long-term contact with the guidewire may lead to bacterial contamination, increasing the risk of postoperative infection. At the same time, the stability of manual operation is poor. Medical staff need to fix the guidewire with one hand for a long time, which is easy to fatigue. In addition, the guidewire material is relatively soft and the length is redundant. Manual support can easily cause the guidewire to bend and shift, affecting the accuracy of the operation. Although there are a variety of vascular interventional auxiliary devices in the prior art, none of them has proposed a systematic solution for the sterile fixation and operation optimization of the extracorporeal guidewire. In response to the above problems, this application proposes a guidewire guide tube for interventional surgery, which achieves dual guarantees of operational convenience and sterile safety through structural innovation.
