Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, in particular to a brain pressure plate for neurosurgery. Background Art

[0002] Brain compression splint is one of the commonly used instruments in neurosurgery. It is mainly used to pull brain tissue, expose deep lesions, and provide a good field of view for deep microsurgery. There are two types of intraoperative traction: continuous traction and intermittent traction. Continuous traction usually refers to continuous traction of brain tissue during surgery, while intermittent traction refers to repeated traction and relaxation of brain tissue. Brain compression splint is a rigid structure with sharp edges. In addition, brain tissue is pulsating. Excessive or inappropriate traction on brain tissue can cause varying degrees of brain edema, brain contusion, cerebral infarction, cerebral hemorrhage and other brain damage. It is the most common iatrogenic damage in neurosurgery.

[0003] When traditional brain pressure plates pull the brain tissue during surgery, there is still a risk of surgical instruments coming into contact with the brain tissue and causing damage to the brain tissue. When a brain pressure plate with a hard structure is used, it is easy to cause damage to the brain tissue during use. When a brain pressure plate with a soft structure is used, the soft structure cannot effectively support the brain tissue, resulting in an incomplete exposure of the surgical field, which in turn affects the progress of the operation. Therefore, traditional brain pressure plates have certain limitations when used. Summary of the invention

When in use, it is fixedly connected to the external inflation tube, and the airbag 22 is inflated through the inflation tube to expand the airbag 22 outward.

[0030] The outer end of the pressure plate 13 can be sleeved with an airbag 25. The airbag 25 has two parts, and the two parts are connected by a connecting tube 26. An air pipe 27 is fixedly installed at one end of the airbag 25. A plurality of connecting tubes 26 are arranged in the middle of the left and right sides of the airbag 25. The connecting tube 26 is located on the outer side of the pressure plate 13. Both ends of the connecting tube 26 are connected to the interior of the airbag 25.

Then the medical staff uses the pressure plate 13 to pull the brain tissue and insert the end with the airbag 25 into the brain tissue. As the pressure plate 13 is inserted, the airbag 25 is brought to the appropriate position in the brain tissue. After being inserted into the appropriate position, the airbag 25 is inflated and the airbag 25 expands outward. At the same time, the airbag 1 22 is deflated and the pressure plate 13 is pulled out. At this time, the surgical site can be stretched open to facilitate the surgical operation.
