Embodiment Construction

[0030] The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples are only used to explain the present invention, but not to limit the scope of the present invention.

[0031] combined with figure 1 and 2 As shown, this embodiment provides a displacement device for an intracranial aneurysm filler, including a basic clipping part, the clipping part includes a first clip arm 1, a second clip arm 2, a deformation part 3 and a drive Department and other basic components. The displacement device for intracranial aneurysm filler in this embodiment is suitable for expanding and improving catheter-based intracranial vascular interventional therapy, and is applied to cerebral blood vessels. Therefore, the clamping range of the clamping part is generally less than 250um, and the clamping range of the clamping part is generally less than 250um. The range of movement is preferably 150um-200um, so it is necessary...

Abstract

The invention discloses a displacement device for an intracranial aneurysm filler, comprising a first clamping arm and a second clamping arm, the first end of the first clamping arm and the first end of the second clamping arm passing through connecting pieces, the second end of the first clamp arm is provided with a first clamp portion, the second end of the second clamp arm is provided with a second clamp portion; the first clamp arm and the first clamp arm An installation space is formed between the two clamping arms, and a deformation part and a driving part are arranged in the installation space, and the deformation part changes between an expanded state and a contracted state under the driving of the driving part. The invention drives the two clamping arms to clamp the filler through the deforming part and the driving part, so as to adjust the position of the filler, so that the filler is in the best position of the intracranial tumor, and the treatment effect is guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a displacement device for intracranial aneurysm fillers Background technique [0002] In recent years, intracranial aneurysms have gradually become a high-incidence disease among middle-aged and elderly people and hypertensive populations. Intracranial aneurysm refers to a tumor-like protrusion of the arterial wall caused by the localized abnormal expansion of the lumen of the cerebral artery. Sexual bulge is the leading cause of subarachnoid hemorrhage. [0003] At present, the treatment methods for intracranial aneurysms include surgical treatment and non-surgical treatment. About 1 / 3 of patients cannot undergo craniotomy because of the shape, location, and physical health of the intracranial aneurysm. The most common non-surgical treatment method is detachable coil vascular embolization, that is, the doctor inserts a catheter into the femoral artery under the guidanc...
