AI Technical Summary

Technical Problem

Traditional scalp skin harvesting methods suffer from time-consuming and labor-intensive procedures, poor intraoperative bleeding control, and inadequate postoperative analgesia.

Method used

The device employs a hemostatic helmet and a headband-mounted compression device. The hemostatic helmet has a circumferential anti-leakage airbag and several injection mechanisms on its lower edge. By inflating and pressing the edge area of ​​the scalp, it prevents the injection fluid from seeping in, and a drive mechanism drives the injection needle to insert into the scalp for multi-point injection. The headband-mounted compression device uses an arc-shaped component and a slider structure to stably fix the puncture needle, simplifying the operation process.

Benefits of technology

It improves the efficiency and hemostatic effect of scalp injection, reduces intraoperative bleeding, simplifies the operation process, reduces the risk of postoperative swelling, enhances analgesia, and avoids side effects.
