Forceps end mechanism of blocking forceps with puncture hole and no damage to renal artery for celioscope

Abstract

The invention discloses a forceps end mechanism of a pair of blocking forceps with a puncture hole and no damage to a renal artery for a celioscope, comprising a forceps rod and a movable arm, wherein the movable arm is pivoted on an external side section of the forceps rod; a protruding blocking edge is arranged at one side of an upper plane of the external side section of the forceps rod, and a renal artery groove is arranged at the other side of the upper plane; and the movable arm is provided with the puncture hole which is communicated with the renal artery groove. When the blocking forceps manufactured by the forceps end mechanism in the invention are utilized to perform celioscope partial nephrectomy and the like, the renal artery is effectively blocked, therefore, an operation is performed in a bloodless state; and meanwhile, renal artery puncture and low temperature perfusion can be performed, thereby protecting kidney functions to the maximum degree. The mechanism has the advantages of reasonable design, simple structure, high success rate, convenient of use and the like.

Description

technical field [0001] The invention relates to a forceps end mechanism of a laparoscopic non-damaging renal artery blocking forceps with puncture holes, which is used for laparoscopic partial nephrectomy and other operations, and belongs to the technical field of clinical medicine and surgery. Background technique [0002] Partial nephrectomy is mainly suitable for benign tumors such as renal cancer with tumor diameter less than 3cm, 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 more difficult to operate. Because the concept of preserving renal function has been affirmed by domestic and international urology circles, this operation has a good prospect. In recent years, with the improvement of laparos...

Problems solved by technology

At present, there are three main methods for rapid cooling of the operated kidney: ①The ice-water mixture protects the kidney from hypothermia. The advantage of this method is that it is relatively easy to implement, but the disadvantage is that it requires a large space, and it cannot be done via the retroperitoneal route, but only through the peritoneal route. surgery, and affect the surgical operation

②The retrograde perfusion of ice saline under endoscope has the advantage of not needing to add new equipment or learn special surgical techniques, but the disadvantage is that the cooling effect is not as fast and uniform as that of arterial perfusion

The only disadvantage is the need for a special blocking perfusion device and laparoscopic renal artery puncture technique, which seriously limits the popularization of this operation
