Skull base repairing device and method

Abstract

The invention discloses a skull base repairing device, which comprises a support rod, a first repairing material and a second repairing material, wherein the top end of the support rod is provided with a first fixing disc; the lower end of the support rod is provided with a moving disc capable of moving on the support rod; a support frame fixedly provided with the first repairing material is arranged between the first fixing disc and the moving disc; a push rod is arranged under the moving disc; and the lower end of the support rod is also provided with a second fixing disc used for fixing the second repairing material. The invention also discloses a skull base surgical repairing method. The repairing device provided by the invention has the advantages that a surgical incision can be conveniently sealed and plugged; the phenomena of intracranial external communication lacuna and cerebrospinal fluid leakage cannot occur; when the repairing device is used, the surgical incisions of other positions of the skull base can be sealed and plugged, so that the surgical pathway is more direct; and the surgical region is more clearly exposed.

Description

technical field [0001] The invention belongs to surgical supplies, and in particular relates to a skull base repair device and method. Background technique [0002] Neuroendoscopy is a technology that uses endoscopes with a diameter of 0.2-0.6 cm to treat intracranial lesions. With the development of neuroendoscopic techniques, it has become a routine treatment to resect tumors in the sellar region and parasellar region of the skull base through extended transsphenoidal approach. However, large skull base bone, dura mater, and local soft tissue defects often occur after resection of the lesion, which increases the possibility of postoperative complications such as cerebrospinal fluid leakage, meningitis, pneumocranium, and encephalocele. [0003] In order to reduce complications, the skull base defect must be repaired after surgery. At present, the surgical incision is enlarged through the transsphenoidal sinus to treat the inside of the skull base. When the surgical site i...

Problems solved by technology

However, large skull base bone, dura mater, and local soft tissue defects in the surgical field often occur after resection of the lesion, which increases the possibility of postoperative complications such as cerebrospinal fluid leakage, meningitis, pneumocranium, and encephalocele.

[0003] In order to reduce complications, the skull base defect must be repaired after surgery. At present, the surgical incision is enlarged through the transsphenoidal sinus to treat the inside of the skull base. When the surgical site is complicated, if it passes through the entrance of the sphenoid sinus, it needs to be enlarged. Internal surgery, when the surgical site is far away from the entrance of the sphenoid sinus, the difficulty of the operation will increase, and the repair of the enlarged sphenoid sinus entrance will be complicated. The operation area is exposed more clearly, but because the slope part cannot be combined with the repair of the skull base after the operation is completed, there will be intracranial and extracranial communication spaces and cerebrospinal fluid leakage, and the skull base cannot be repaired
