Scalp retractor for separating scalp artery

Abstract

The invention provides a novel scalp retractor for separating a scalp artery and belongs to the technical field of medical instruments. A conventional scalp double tooth top sharp hook has severe damage to scalp, a retracted scalp edge blocks a surgical area and the accidental injury of a target artery directly affects successful performance of a surgery and even causes failed surgery. The technical scheme of the inventive patent is that: the novel scalp retractor for separating the scalp artery is applied to various superficial skin surgeries in the surgery field of a horizontal hook retractor and comprises a small blunt cerebral plate hook which is connected with a tough, well-adaptable and replaceable rubber band and a sharp single tooth hook. The invention has the advantages that: the novel scalp retractor for separating the scalp artery can prevent a projecting scalp edge from blocking the surgical area, and avoid frequent fall of a scalp hook and the accidental injury of the target artery; and the novel scalp retractor contributes to successfully and efficiently separating a superficial temporal artery or an occipital artery so as to establish a communication cycle between an internal carotid and an outer artery.

Description

technical field [0001] This patent relates to the technical field of medical instruments and devices, more specifically a novel scalp retractor for separating scalp arteries. Background technique [0002] Patients with ischemic moyamoya disease due to congenital occlusion of the internal carotid artery, or patients with occlusion or stenosis of one side of the internal carotid artery caused by atherosclerosis, often experience recurrent cerebral infarction, which can cause hemiplegia and aphasia in severe cases. Establishing an effective internal and external carotid artery communication circulation is a shortcut for the treatment of cerebral ischemia. The superficial temporal artery and the occipital artery are the most available branches of the external carotid artery. The current minimally invasive neurosurgical techniques require the isolation of the superficial temporal artery or the occipital artery with minimal trauma, followed by direct or indirect anastomosis of the...

AI Technical Summary

Problems solved by technology

The traditional double-toothed sharp retractor for the scalp is very damaging to the scalp, and it is easy to cause accidental damage to the superficial temporal or occipital artery; the other end of the scalp hook needs to be attached and fixed on the erected instrument tray, and the pulling direction is inclined, unstable and easily fall off

Pulling the raised scalp edge to block the operation field, accidental damage to the target artery, etc., directly affect the smooth progress of the operation, and in severe cases, the operation fails
