Clinical Scorecard: Innovative Surgical Assistance System for Continuous Resection of Brain Tumors: Introduction of Continuous Tumor Resection Forceps and Mechanisms for Tumor Cell Separation, Dehydration, and Isolation

At a Glance

Key Highlights

• Complete tumor resection (≥90-95%) significantly improves 5-year survival rates in brain tumor patients.
• Continuous tumor resection forceps enable continuous tumor removal with integrated suction and saline reflux cleaning.
• Separation and dehydration mechanisms reduce dilution of tumor cells for accurate flow cytometry-based intraoperative malignancy diagnosis.

Guideline-Based Recommendations

Diagnosis

• Use intraoperative rapid diagnosis with pathological specimens obtained via biopsy to determine tumor malignancy.
• Employ flow cytometry with fluorescent DNA staining for fast malignancy diagnosis of isolated tumor cells.

Management

• Maximize tumor resection ratio while preserving normal brain tissue to reduce recurrence and improve survival.
• Utilize continuous tumor resection forceps to facilitate continuous tumor removal and increase specimen number.
• Incorporate surgical navigation systems integrating neural pathways and vascular structures to guide resection.

Monitoring & Follow-up

• Monitor tumor cell concentration during intraoperative diagnosis to avoid dilution effects from reflux cleaning water.
• Display diagnostic results on navigation system to guide extent of tumor extraction.

Risks

• Avoid injury to normal brain tissue to prevent sequelae such as speech disorders or hemiplegia.
• Minimize tumor cell leakage by ensuring adequate sampling and precise excision range determination.

Patient & Prescribing Data

Patients undergoing surgical resection of malignant brain tumors

Higher tumor resection ratios (≥90-95%) correlate with improved 5-year survival; continuous resection and rapid diagnosis support maximizing resection while minimizing normal tissue damage.

Clinical Best Practices

• Determine exact tumor extraction range intraoperatively using rapid pathological diagnosis to balance maximal tumor removal and normal tissue preservation.
• Use continuous tumor resection forceps with suction and saline reflux to enable continuous tumor removal and reduce surgeon burden.
• Implement separation and dehydration mechanisms to prepare tumor cells for accurate flow cytometry diagnosis.
• Integrate intraoperative navigation systems with neural and vascular pathway mapping to improve surgical precision.
