Summary
This study shows that partial splenectomy using an electromagnetic thermal system is a safe and effective method for achieving hemostasis. This technique preserves splenic function while minimizing blood loss during the procedure.
Area of Science:
- Surgical Innovation
- Medical Devices
- Veterinary Surgery
Background:
- Partial splenectomy aims to preserve splenic function, but achieving hemostasis is challenging.
- Traditional methods for partial splenectomy can be complex and prone to bleeding.
Purpose of the Study:
- To evaluate the feasibility and safety of partial splenectomy using a novel electromagnetic thermal surgery system.
- To assess the hemostatic capabilities of the electromagnetic system in a porcine model.
Main Methods:
- A porcine model (Lanyu pigs) was used for partial splenectomy.
- An electromagnetic thermal system with comb-needle arrays was employed to achieve hemostasis.
- Surgical procedures and subsequent histological examinations were performed to assess outcomes.
Main Results:
- Partial splenectomy duration averaged 10 minutes with no blood loss.
- The cut splenic surface demonstrated effective coagulation and no oozing.
- Histological analysis confirmed coagulative necrosis and vascular clot formation.
Conclusions:
- The electromagnetic thermal system provides effective hemostasis for partial splenectomy.
- The procedure is demonstrated to be safe and technically feasible in a porcine model.
- This system offers a promising approach for spleen-preserving surgery.
