A skull dura separation device

Abstract

The invention discloses a skull dura separation device, comprising an arc sheath and an inner core, the inner core is movably connected inside the arc sheath, one end of the inner core is provided with a tip head, and the outer surface of the inner core is close to the tip One side of the head is provided with a spreading bag, the other end of the inner core is fixedly connected with an injection head, and one side of the pointed head is tilted upward at an angle of 15 degrees. The skull dura mater separation device, when the craniotomy is drilled, the device is inserted under the skull and on the dura, and the direction is changed to be parallel to the skull surface through the radian sheath, and the dura is separated from the skull by pushing the inner core. It is convenient to separate the dura mater. During the insertion process, the medical staff can know the depth of the insertion of the two through the nicks on the surface of the inner core and the curved sheath and the evaluation sheet, and the staff can use the injection tube to inflate through the injection head, The expansion bag is inflated and separated by the force of its expansion.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a skull dura separation device. Background technique [0002] The periosteum is a strong connective tissue envelope covering the surface of the bone except for the joints. At the bone end and tendon attachment site, it is very densely attached to the bone, and the periosteum in other parts is thick and easily peeled off from the bone. [0003] For patients with cerebral hemorrhage, especially those with hypertensive cerebral hemorrhage, a head CT examination is performed after the onset of the disease. [0004] The general steps of craniotomy are: first, make a U-shaped incision on the scalp on the patient's affected part, separate the scalp, muscle and periosteum, then use the cranial power device to drill holes in the skull, and then use a milling cutter The skull was sawed along the path from one bone hole to the adjacent bone hole, the skull flap was pryed up with a...

AI Technical Summary

Problems solved by technology

[0006] In view of the fact that the milling cutter in the prior art is likely to saw through the dura mater, resulting in postoperative cerebrospinal fluid leakage, time-consuming and long, it is easy to cause serious consequences such as intraoperative hypotension or shock or even death, and it is inconvenient to operate and low in efficiency. Insufficient, the present invention provides a kind of cranial dura mater separation device, possesses the advantage that can facilitate medical staff to carry out the separation work of skull and inner periosteum, has improved work efficiency, and safety is high, has solved the problem that the above-mentioned background technology raises
