Abstract

The invention relates to the technical field of medical equipment, and discloses a multifunctional sheath tube. The sheath tube comprises a sheath tube body; a connecting piece is arranged at the nearend of the sheath tube body; the connecting piece comprises a connecting piece housing connected to the sheath tube body and a three-way valve arranged on the connecting piece housing; the three-wayvalve is in sealing fit with the connecting piece housing; a thrombus aspiration assembly is connected to the connecting piece housing; an instrument leading-in channel is formed between the sheath tube body and the connecting piece housing, and a thrombus aspiration channel is formed among the sheath tube body, the connecting piece housing and the thrombus aspiration assembly; and the three-way valve is used for alternatively opening the instrument leading-in channel or the thrombus aspiration channel. The embodiment of the invention not only can be independently used as a leading-in sheath tube, but also has a thrombus aspiration function, so that thrombectomy steps can be reduced, and the operation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a multifunctional sheath. Background technique [0002] Minimally invasive endovascular interventional surgery has gradually become the mainstream trend in the treatment of vascular diseases. The implementation of mechanical thrombectomy requires the puncture of blood vessels through the puncture sheath, and the introduction of surgical instruments with the introduction of the sheath. Taking endovascular thrombus removal surgery as an example, the mainstream minimally invasive interventional therapy requires mechanical thrombectomy through a thrombectomy stent and a suction catheter, and both the thrombectomy stent and suction catheter must be introduced with the introduction sheath. At present, the most cutting-edge thrombectomy method is the combined use of a thrombectomy stent and a suction catheter. In the existing technology, three devices, the introduction shea...
