Problems solved by technology

[0002] With the development of endovascular surgery and the promotion of minimally invasive surgery, there are more and more minimally invasive surgeries involving perforation of endovascular diaphragm and stent graft. However, due to the particularity of such perforation, there is a lack of special Hole-opening utensils, mainly through out-of-range use and patchwork use of conventional utensils
Although these conventional instruments can also achieve the effect of membrane rupture, the accuracy and safety of membrane rupture are difficult to guarantee. During the operation, the puncture position is easily shifted and the puncture is too deep, causing damage to surrounding tissues and blood vessels, and endangering the patient in serious cases. patient life
In addition, the patchwork of multiple instruments also makes it easier to make mistakes during the operation, and the operation time is also prolonged

Abstract

The present invention provides a membrane rupture device for membrane rupture of patients' blood vessels, which comprises an operating mechanism for performing membrane rupture; a hole reaming part, wherein the hole reaming part is disposed at one end of an operating mechanism in an axial direction of the operating mechanism; and a rupture needle disposed along an axial direction of the operatingmechanism near a distal end of the hole reaming member, wherein the rupture needle is configured to form a rupture hole in the membrane by operation of the operating mechanism, the hole reaming part is configured to a membrane rupture hole, and a pore diameter of the membrane rupture hole is enlarged by the operation of the operating mechanism. The membrane rupture device of the invention can be used for an intracavity diaphragm and a stent graft to realize rapid membrane rupture and hole reaming, and avoids mistakes caused by alternating instruments and long operation time.

Description

technical field [0001] The present invention relates to a medical device, and more particularly, to a membrane rupturer for performing membrane rupture in a patient's blood vessel. Background technique [0002] With the development of endovascular surgery and the promotion of minimally invasive surgery, there are more and more minimally invasive surgeries involving perforation of endoluminal diaphragm and stent graft. However, due to the particularity of such perforation, there is a lack of special The hole-opening utensils are mainly used through out-of-range use and patchwork use of conventional utensils. Although these conventional instruments can also achieve the effect of membrane rupture, the accuracy and safety of membrane rupture are difficult to be guaranteed. During the operation, the puncture position is easily shifted and the puncture is too deep, causing damage to surrounding tissues and blood vessels, and endangering the patient in severe cases. patient life. ...
