A 3D fixing device for trocar and blood vessel clip

Abstract

The invention discloses a 3D trocar and vascular clamp fixing device. The 3D trocar and vascular clamp fixing device comprises a base, wherein a triangular block is inclined at the upper end of the base according to a certain angle; an elliptical through hole is formed in one side of the outer wall of the triangular block; two convex blocks are arranged at each of the upper end and the lower end of the outlet of the elliptical through hole; a T-shaped groove is formed in each convex block; a limiting block is arranged inside each T-shaped groove; a rubber sleeve is arranged at one end of each limiting block; an arc-shaped pressing block is arranged at one end, away from the limiting block, of each rubber sleeve; a protruding strip is transversely arranged at the middle part of the lower end of the base; a clamping through hole is transversely formed in the base; a rolling groove is formed in one end, away from a second spring, of each clamping block; a ball is arranged inside the each rolling groove. The 3D trocar and vascular clamp fixing device is simple in structure and easy to operate, can fix a trocar and a vascular clamp at the same time, reduces risks of laparoscopic renal artery hypothermic perfusion surgery, is convenient, fast and ingenious to use, and is suitable for wide popularization.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a fixing device for a 3D trocar and a blood vessel clip. Background technique [0002] Partial nephrectomy is mainly suitable for benign tumors such as renal cancer with tumor diameter less than 4cm, solitary renal tumor, bilateral renal tumor, and renal hamartoma, as well as segmental renal vascular malformation, duplication renal malformation with poor drainage, and limited Renal injury with hemorrhage and urine extravasation, multiple calculi confined to the upper or lower pole of the kidney, and other diseases are difficult to operate. Later, with the improvement of laparoscopic surgical instruments and the advancement of surgical techniques, laparoscopic partial nephrectomy was gradually successfully carried out at home and abroad. However, the surgical requirements are high, not only to remove the lesion, but also to suture the cut surface of the kidney within a...

Problems solved by technology

The only disadvantage is the need for a special blocking perfusion device and laparoscopic renal artery puncture technique, which severely limits the popularization of the operation, and the prior art renal artery hypothermic perfusion robot-assisted laparoscopic left partial nephrectomy The interventional department needs to place an arterial balloon from the femoral artery. The balloon can block the blood vessel, and the middle tube is used to flush the perfusion fluid. The operation time is long and the process is complicated, which increases the risk of the patient
