Pituitary adenoma operation patch and producing method thereof

Abstract

The invention relates to a pituitary adenoma operation patch and a producing method thereof. The patch is filled at a skull base bone defect opening of pituitary adenoma operation, and the edge shape of the patch is matched with the edge shape of the bone defect opening; the patch is a piece made of a PCL-TCP material. The producing method of the patch comprises the following steps: performing data processing by virtue of computer image processing and three-dimensional substantive design software, and performing 3D printing to produce the patch. The pituitary adenoma operation patch has the beneficial effects that the advantages of a computer image processing technique is utilized, the pituitary adenoma operation patch is produced by combining the novel material PCL-TCP with the 3D printing technique, and then the bone defect is repaired. The pituitary adenoma operation patch is high in producing speed, high in structural property, excellent in biological property, high in precision and high in repair tightness, the surgery cost can be reduced, the operation time is shortened, the postoperative complications are reduced, the operative wound is alleviated, postoperative recovery is promoted, and the benefits of patients are maintained.

Description

technical field [0001] The invention belongs to neurosurgery equipment, in particular to a surgical patch for pituitary adenoma and a production method thereof. Background technique [0002] Pituitary tumors are common intracranial tumors with the third highest incidence rate, accounting for about 10% of intracranial tumors. They are a group of tumors that arise from the anterior and posterior pituitary lobes and residual epithelial cells of the craniopharynx. Pituitary tumors bring huge health hazards, mental stress, and material consumption to patients and families. At the same time, if some pituitary tumors do not undergo systematic diagnosis and treatment, the survival time of patients will be greatly reduced. At present, endoscopic transnasal-sphenoidal pituitary tumor resection is the most widely used in clinical practice. The surgical approach is to enter the sphenoid sinus through the nostrils, open the sellar floor, and remove the tumor; in the process of opening t...

Problems solved by technology

The disadvantages of the above traditional methods are that the shape is not accurate, the model style is rough, and it often requires repeated pruning attempts, which prolongs the operation time and increases the risk of the operation

Moreover, the shape of the hand-cut patch cannot fit well with the opening of the bone defect, and the repair effect cannot be guaranteed. Sometimes it is necessary to take the fascia tissue from the patient itself for repair, which increases unnecessary surgical trauma.

Moreover, bone cement is an expensive material, and the price of a small bottle of bone cement is about 30,000 yuan. Titanium alloy is also a precious metal material, and material waste is inevitable during the cutting process[t1]
