Description

Internal carotid artery injury hemostatic forceps in neuroendoscopy transnasal operation

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to internal carotid artery injury hemostatic forceps among neural scope intranasal surgery.

Background

At present, with the development of endoscopic neurosurgery, the operation range is gradually enlarged. The surgical field often involves the perivascular regions of the large vessels, such as the internal carotid artery and its branches, the basilar artery and its branches. Because of the long-term compression and invasion of lesions such as tumor and the like, the hemorrhage of large blood vessels in the operation is one of lethal complications in endoscopic skull base operation and is an important factor for hindering the development of endoscopic skull base surgery. The existing craniocerebral operation hemostasis methods comprise bipolar coagulation hemostasis, muscle piece compression hemostasis, blood vessel suture hemostasis, interventional intravascular hemostasis and the like. The bipolar coagulation hemostasis and muscle tablet compression hemostasis are only suitable for blood vessel hemostasis when the blood vessel is broken, and the hemostasis effect is not exact. The blood vessel suture hemostasis is difficult to realize or generally suitable in most cases due to the factors that an operation channel of an endoscope through the nasal skull base is narrow, the degree of freedom of instruments is limited, the distance between an operation field and a nostril is long, massive hemorrhage easily pollutes an endoscope lens and the like. Interventional endovascular hemostasis is an endovascular rehabilitation method, which is premised on the temporary control of major hemorrhage. At home and abroad, no effective hemostatic measure for injury of internal carotid artery and branches thereof in neuroendoscopy nasal operation exists, especially when the laceration is large.

Recently, hydrogel and hemostatic membrane containing hemostatic hydrogel components have good application prospect for hemostasis of large blood vessels, the hemostatic membrane needs tens of seconds of attaching time to the surface of tissue for completing blood coagulation, and doctors usually adopt the existing minimally invasive surgical instruments to fill cotton sheets for hemostasis due to the lack of special instruments for hemostasis by adopting hemostatic membranes at present, so that acute compression occlusion of blood vessels is often caused, or aneurysm clips are used for completing control of blood flow near and far ends of lacerations, and sealing operation of lacerations cannot be completed. The end of the current hemostatic forceps can not be matched with the vascular wall to be unsuitable for bearing the hemostatic membrane, and the size of the outer diameter of the blood vessel is different, so that the hemostatic membrane can not be tightly attached to the blood vessel in high-flow hemorrhage, hemostasis failure is caused, the hemostasis efficiency is greatly reduced, and the life health of a patient is threatened even.
