Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, in particular to a disposable intracranial hematoma removal balloon catheter kit. Background Art

[0002] Traditional brain tissue retraction and surgical channel establishment mainly rely on brain compression plates (stainless steel sheets) to manually utilize the anatomical structure of the skull and brain to retract brain tissue, which mainly relies on the professional skills, experience and patience of the surgeon. In addition, the process of retracting brain tissue is prone to damage to cerebral blood vessels and nerves. Brain traction injuries can be seen everywhere. After retraction, due to the latent characteristics of brain tissue, the expanded channel is prone to shrink and become smaller, affecting surgical operations. Direct retraction using a brain compression plate requires a large bone window for surgical operations, which is traumatic and prone to infection. The patient's recovery time is long, which brings great pain and a heavy economic burden to the patient. For surgeries that require brain parenchyma retraction, the brain compression plate is no longer capable of doing so and needs to be cut with an electrocoagulation knife. The electrocoagulation knife can easily cause irreversible damage to the nerves and blood vessels in the brain tissue, causing the brain to lose some functions, or even leading to the patient's death. For this reason, we have proposed a disposable intracranial hematoma removal balloon catheter kit. Summary of the invention
