Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0027] The embodiment of the invention discloses an anti-sinking device, a decompression device for removing a skull craniotomy and a use method thereof. refer to Figure 1-Figure 3 , the anti-sinking device is used to prevent the skull plate 1 from sinking, and the anti-sinking device includes a tension wire 3, two rotating clamps 4, a Z-shaped plate 5 and two connecting pieces 6, the two said The connector 6 is used to be arranged symmetrically on the two left and right skull plates 1 respectively, the Z-shaped plate 5 is used to be arranged on the skull 2, and one end of the two rotating clamps 4 is connected to the two left and right skull plates 1 respectively. The connecting piece 6 is rotationally connected, and the other ends of the two rotating clamping plates 4 are provided with projections 7 for winding the tension wire 3, and the Z-shaped plate 5...

Abstract

The invention relates to an anti-sinking device which comprises a tensioning line, two rotary clamping plates, a Z-shaped plate and two connecting pieces, wherein the two connecting pieces are arranged on two skull plates, the Z-shaped plate is arranged on a skull, a protruding block is arranged on one side of the other end of each rotary clamping plate, the tensioning line bypasses the protruding blocks and the Z-shaped plate, and the rotary clamping plate can be clamped with the Z-shaped plate. The skull decompressive craniectomy device comprises two skull plates, a connecting assembly and the anti-sinking device, wherein one side of each skull plate can rotate around the skull. The using method comprises the steps that the connecting assembly and the connecting pieces are arranged on the two skull plates and the skull, and the Z-shaped plate is arranged on the skull; and the tensioning line is pulled, and the rotary clamping plates are clamped to the Z-shaped plate. According to the invention, a gap is formed in the connecting position of the two skull plates, and the two skull plates can effectively buffer intracranial pressure; and after the intracranial pressure recovers, the rotary clamping plates are clamped with the Z-shaped plate, so that the skull plates are prevented from sinking.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an anti-subsidence device, a skull craniectomy decompression device and a use method thereof. Background technique [0002] Most patients with traumatic brain injury, cerebral hemorrhage and various intracranial lesions need to undergo craniotomy. Patients with cerebral hemorrhage and tumors often have brain tissue swelling after surgery, and the skull plate needs to be removed at this time. After removing the hard skull, the resulting space is 15.9cm 3 ~347.4cm 3 , average 73.6cm 3 . Decompressive craniectomy can effectively protect brain tissue by increasing intracranial compensation space, reducing intracranial pressure, and restoring cerebral blood perfusion. This method is not only economical, but also can reduce patient mortality and improve neurological function. However, the skull defect caused by decompressive craniectomy can cause further craniocerebral inju...
