Description

Rongeur with blood vessel monitoring function

Technical Field

The invention relates to a medical appliance, in particular to a rongeur with a blood vessel monitoring function.

Background

With the increasing perfection of the nasal endoscope surgical technology, the scope of the endoscopic surgery is continuously expanded, the patients with the existing tumor invading the skull base can only adopt conservative treatment, and due to the fact that a plurality of important blood vessels are involved in the nasal skull base surgery, such as cavernous sinus, external carotid artery branches, internal carotid artery and the like, any blood vessel accidentally injured in the surgery can cause massive hemorrhage, particularly the accidental injury in the internal carotid artery surgery, and the consequences are always fatal. The nasal endoscopic surgery has the advantages of sufficient illumination, but the position is deep, the space is narrow, the device operation is difficult, if the intraoperative hemorrhage is large, the hemostasis is very difficult, the death rate is extremely high, even if the hemostasis is performed through compression, the digital angiography is required to be performed after the operation, and the life quality of a patient is obviously reduced although the patient lives after the treatment. The range of tumor lesions related to skull base operation is wide, and partial tumor tissues and blood vessels are not obviously demarcated or affected bone substances and blood vessels are not demarcated clearly, so that side injury in operation is easily caused.

At present, the rongeur used in clinical operation can bite off larger sclerotin, but the rongeur body and the rongeur body are heavier, so that the rongeur body is not beneficial to removing sclerotin at a fine part of a nose-skull base to cause lesion residue, or the rongeur body blocks the operation visual field of an endoscope to cause operation accidental injury of important structures.

The existing forceps body does not have a blood vessel monitoring function, and can easily cause accidental injury to important blood vessels (internal carotid artery and the like) in the skull base region to cause fatal hemorrhage.
