摘要:
The present invention relates to an ultra mini percutaneous nephro lithotomy access sheath for removing stones from the kidney. This ultra mini PCNL access sheath has a diameter of about 3-4 mm which is quiet small compared to the prevalent PCNL sheaths used. So a small puncture is to be made in the kidney to remove stones causing minimal damage and negligible blood loss due to which the patient can be discharged within 24 hours. Moreover, the ultra mini PCNL access sheath has a small channel to inject water in the kidney which increases pressure in the kidney due to which the disintegrated stone fragments escape to a low pressure area found in the ultra mini PCNL access sheath and can be removed by suction. This minimizes the damage to the kidney by manual removal using forceps.
