Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to an auxiliary instrument for a nephron operation retained under a laparoscope.
Background
With the gradual maturity of the laparoscopic technology, the laparoscopic nephron-retention surgical technology is gradually mastered and applied by doctors, and the indexes of the operation time, the intraoperative hemorrhage amount and the like are gradually the same as those of an open operation, so the laparoscopic nephron-retention surgical technology is gradually a main means for minimally invasive surgical treatment of the renal carcinoma. However, in the laparoscopic nephron retention surgery, it is difficult to completely block blood supply to artery and vein of kidney as in the conventional open surgery, and then the method of adding ice debris around the part of kidney to be retained is adopted to cool down, so that the warm ischemia time of the kidney tissue to be retained is prolonged, thereby damaging renal parenchymal cells, finally causing irreversible damage to renal function, and further affecting the recovery of postoperative renal function. Therefore, when the nephron operation is retained under the laparoscope, the operation can completely remove the tumor under the condition of clear operation visual field, and how to better protect the residual kidney function becomes a focus of attention and a technical difficulty of the operation. Especially for patients with isolated kidney and disease of contralateral kidney, the protection of kidney function is more important. Intensive research studies by many scholars aiming at the preservation of renal function in laparoscopic nephron surgery have led to the hope that this problem can be solved by improving the related art. From the aspect of surgical technique, Gill et al propose a renal artery branch blocking technique to selectively block blood vessels supplying tumor regions to achieve the purpose of protecting renal function, and also propose that after the renal medullary layer is closed, the blocking can be released to restore the renal blood vessels to shorten the warm ischemia time of the renal tissue, thereby maximally preserving renal function. However, this technique requires very high requirements for preoperative judgment, intraoperative operating skills, etc., is highly dependent on the operative experience of the operator, and does not allow for a specific vascular supply for all tumors, and also increases the possibility of vascular rupture when separating the branch vessels. Gill et al also propose creating a zero ischemic state by drug-induced hypotension, but this approach is more complex and more selective to the patient, in terms of physical factors, hemodynamics, etc. On the other hand, from the aspect of creating a low-temperature operation environment, Landman and Crain and the like propose a method for cooling the kidney by performing ice water perfusion on the ureteral cannula during the operation. By carrying out ice water perfusion in the kidney collection system in a retrograde manner, the core temperature of the kidney parenchyma can be reduced to about 23 ℃, but the technology is complex to operate, the cooling effect is related to the surface area of the collection system, and the influence of long-time high-pressure perfusion on the kidney function is also not negligible. Janetschek adopts a method of renal artery ice water perfusion in the operation for cooling protection, and cannot be further popularized due to complex operation. To date, no simple, easy to use, and highly operable instrument and method for maximizing residual kidney function preservation in laparoscopic nephron procedures has been developed.
Aiming at small tumors positioned at the upper and lower poles of the kidney, the complete blockage of the renal artery causes no blood supply to the whole kidney, and the whole kidney is in an ischemic state, so that the irreversible damage of normal kidney tissues is caused. Therefore, a medical instrument for laparoscopy nephron retention surgery is urgently needed, which avoids blocking the blood supply of the whole kidney and furthest retains the function of the residual kidney.
