Plaster for craniotomy

Abstract

A plaster for craniotomy is a silica gel plate-shaped body with two smooth surfaces. A plurality of cylindrical through holes are arranged on the plate-shaped body, and the thickness of the plate-shaped body is 1.5mm-2.0mm. The diameter of the bottom surface of each through hole is 3.0mm-4.0mm, and the distance between every two through holes is 10.0mm. The plaster can meet requirements for reducing bleeding and damage to brain tissue caused by operation separation during cranioplasty. By means of the plaster for the craniotomy, surgical dissection is conveniently performed during the cranioplasty, time is shortened, and bleeding is less. In addition, the plaster for the craniotomy is simple in structure and suitable for industrial production.

Description

technical field [0001] The invention relates to a patch for craniotomy. technical background [0002] According to the epidemiological survey of craniocerebral trauma in East China in 2008, there were 15,611 cases of various craniocerebral injuries in 2004, of which 3,871 were treated with surgery. At present, it is conservatively estimated that the number of craniocerebral injuries in the whole country should be around 50,000. . [0003] After various craniotomies in neurosurgery, according to the patient's condition, some patients need to remove the skull bone flap to achieve the purpose of buffering cerebral edema, brain swelling, reducing intracranial pressure, and reducing the application of postoperative dehydrating agents, especially in severe cases. For patients with craniocerebral injury, most of the skull flaps must be removed after craniotomy to buffer cerebral edema, brain swelling, and reduce intracranial pressure. Generally, 3 to 6 months after the operation ...

AI Technical Summary

Problems solved by technology

[0005] Since cranioplasty is a second operation, its tissue adhesion is serious. During the separation process, the dura mater or sometimes very thin fibrous tissue on the surface of the brain is easy to be peeled off, causing injury or cerebrospinal fluid leakage, resulting in postoperative trauma. Subcutaneous or repaired bone flap effusion, therefore, in current cranioplasty, 2 / 3 of the time is spent on separating skin and muscle flaps, repeated hemostasis, time-consuming and labor-intensive
