Cutting device and cutting method for neurosurgery artificial meninges

Abstract

The invention discloses a cutting device and a cutting method for neurosurgery artificial meninges. The cutting device comprises a cutting platform, a projector, a pattern adjusting lens, a lens guide rod and a guide rod rotating mechanism, wherein the cutting platform is used for placing the artificial meninges; the projector is used for projecting a cutting pattern onto the cutting platform; the pattern adjusting lens is positioned between the projector and the cutting platform and is used for zooming the cutting pattern projected by the projector; the pattern adjusting lens is arranged on the lens guide rod in a sleeving manner through a threaded part; the guide rod rotating mechanism is used for driving the lens guide rod to rotate so as to enable the pattern adjusting lens to be close to or separated from the projector; and a grid part for measuring the size of the cutting pattern is arranged on the cutting platform. The cutting device and the cutting method disclosed by the invention have the benefit that the cutting of the artificial meninges is quicker, more convenient and more accurate.

Description

Technical field [0001] The present invention relates to the field of tailoring techniques of biomaterials, and in particular, there is a tailoring device and a tailoring method for neurosurgical meningum. Background technique [0002] Artificial Mesh, which is artificial dura maater, which uses biological materials to make human mening membranes for alternatives for brains, spinal cord injury, tumors and other craniocerebral diseases. Repair, prevent severe complications of cerebrospinal fluid leakage, intracranial infection, cerebral bulk, brain bond and scar, etc. to restore its integrity. Stitch the artificial brain film to the defect site, block the artificial brain edge by the sealing agent to prevent the hydrandon from leaking from the cutting suture; At the edge of the end, a layer of binder is applied to the cross edge of the two, such as the n-butyl cyanoacrylate, which will give a better effect and significantly shorten the surgical time. [0003] At present, there is a...

Problems solved by technology

[0003] At present, it is necessary to use artificial dura mater for dura mater repair after neurosurgery. Due to different cutting methods of dura mater (such as "+" incision, "T" incision, four-pointed star incision, arc incision or radial incision, etc.), it is necessary to repair the dura mater. During the process, the artificial dura mater needs to be cut according to the different shapes of the human dura mater. At present, there is still no corresponding tool for cutting the artificial dura mater. It is the phenomenon that the cut artificial meninges do not correspond to the opening of the dura mater of the human body and cannot be sutured

This requires re-use of a new artificial dura mater and cutting again. Such multiple cuttings will result in waste of artificial dura mater and increase the use of surgical consumables. Moreover, multiple cuttings will take a lot of time, resulting in untimely suturing and increasing the number of patients undergoing surgery. Risk, in severe cases, the dura mater is not repaired tightly, resulting in cerebrospinal fluid leakage and increasing the risk of postoperative infection
