Novel use of silica gel

Abstract

The invention provides novel use of silica gel. Silica gel can be applied in the aspect of an isolating membrane used for cranioplasty. The isolating membrane serves as a surgical consumable, forms a layer of separation between dura mater and muscle in decompressive craniectomy, has excellent histocompatibility without any foreign body reaction, can effectively reduce damage caused during the separation between the dura mater and a flap, and further reduces the occurrence rate of infection as well as subdural effusion; moreover, during the process of myocutaneous flap separation in secondary repair surgery, almost no newborn blood vessel exists in the level, therefore, during the separation process, the possibility of bleeding is very low, the difficulty in separation is greatly reduced, furthermore, postoperative temporalis edema is greatly reduced, and the novel use of silica gel has a very important clinical application value.

Description

technical field [0001] The invention relates to a new application of silica gel. Background technique [0002] In neurosurgery, craniotomy hematoma evacuation + decompressive craniectomy is the most common operation, which is carried out in neurosurgeries of hospitals at all levels. It is the most common operation in neurosurgery. The two-stage operation performed on the physiological structure is also very common in clinical practice. The above two operations are connected before and after, but due to the adhesion of the dural repair material to the arachnoid, brain tissue, and muscle after decompressive craniectomy, as well as the massive formation of scar tissue, new granulation tissue, and new blood vessels, the second-stage surgery was performed. During surgical repair, it is difficult to separate the gap between the dura mater and the muscle during cranioplasty, which also leads to a higher incidence of temporal muscle swelling and subdural effusion after secondary re...

AI Technical Summary

Problems solved by technology

The above two operations are connected before and after the decompressive craniectomy, but due to the adhesion of the dura mater repair material to the arachnoid, brain tissue and muscle, as well as the massive formation of scar tissue, new granulation tissue and new blood vessels after decompressive craniectomy, the second-stage surgery was performed. During surgical repair, it is difficult to separate the gap between the dura mater and the muscle during cranioplasty, which also leads to a higher incidence of temporal muscle swelling and subdural effusion after secondary repair surgery. Clinically, post-cranioplasty About three days later, swelling of the temporalis muscle and eyeball on the repaired side can be seen almost everywhere, and even the eyeball on the affected side cannot be opened. It can only be relieved after a period of detumescence treatment, and this problem is also likely to cause swelling after repairing. Increased infection rate

[0003] It can be seen that the application of dura mater patch in the operation has been very common in recent years. In the subsequent two-stage cranioplasty, the process of separating the skin and muscle flap will be relatively troublesome, due to the serious adhesion between the dura mater and the muscle. , scar shrinkage, etc. lead to separation difficulties, and the separation of layers and gaps is unclear, resulting in dura mater damage or separation of skin flaps resulting in too thin flaps, or excessive damage during separation, resulting in postoperative subdural fluid accumulation, and even infection.
