Problems solved by technology

[0002] After craniocerebral surgery removes the bone flap, the patient's brain develops edema. The current technical method is to perform secondary plastic surgery after the edema is eliminated, and then implant the bone flap made of silica gel or bone cement. The hospitalization time of the patient is long. Both physical and mental pain, medical expenses are also relatively large

Abstract

The invention relates to a method for producing the artificial skeleton in brain surgery. Wherein, it comprises that mixing hydroxypropyl cellulose, methyl silicon rubber, dolomol and medical talcum powder to be fed into particle maker; then mixing it with acroleic acid resin, polyethylene 2000F, skeleton resin, acacia gum and solidifier, to be fed into protrude machine to form material; feeding it into hydraulic shaper to be compressed into skeleton. The invention has high strength and stable property. It can float with the expansion of dropsy brain organism, and it can recover when the dropsy is released.

Description

Technical field: [0001] The invention belongs to the technical field of medical appliance manufacturing, and relates to a craniocerebral artificial bone flap and a manufacturing method. Background technique: [0002] After the cranial surgery removes the bone flap, the patient's brain develops edema. The current technical method is to perform secondary plastic surgery after the edema is eliminated, and then implant the bone flap made of silica gel or bone cement. The hospitalization time of the patient is long. The body and spirit are all painful, and the medical expenses are also relatively large. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a one-shot artificial bone flap after craniocerebral surgery. [0004] The invention also provides a method for making the bone flap. [0005] The technical scheme for solving the problem of the present invention is to adopt the bone flap main body that is consistent wi...
