Abstract

The invention belongs to the technical field of medical apparatuses and instruments, and provides a self-locking type half kidney loop ligature for a minimally invasive surgery. The self-locking type half kidney loop ligature for the minimally invasive surgery is formed by a kidney ligature (1), a hoop (2), a connecting rod handle (3), a hoop clamping sheet (4), a self-locking pull sheet (5), a self-locking sliding block (6), a sliding block clamping sheet (7) and a movable handle (8). According to the self-locking type half kidney loop ligature for the minimally invasive surgery, by means of controlling the kidney ligature (1), only the blood supply of the kidney of a tumor growth end can be cut off, the effect of tumor removal is guaranteed, blood loss volume in the surgery process is reduced, and most importantly, the ischemia time of reserved parts of the kidney is reduced to zero; the fact that blocking on the blood supply of the whole kidney is avoided, the functions of the reserved parts of the kidney are protected to the maximum extent, and the significance of nephron-sparing surgeries under a peritoneoscope is fully embodied.

Description

technical field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a self-locking hemi-kidney band for maximally retaining residual kidney function in laparoscopic nephron-preserving surgery. Background technique

[0002] With the gradual maturity of laparoscopic technology, laparoscopic nephron-sparing surgery techniques have been gradually mastered and applied by the majority of physicians, and its operation time, intraoperative blood loss and other indicators are gradually the same as those of open surgery, so laparoscopic nephron-sparing surgery Surgery has increasingly become the main means of minimally invasive surgical treatment of small renal cell carcinoma. However, because laparoscopic nephron-sparing surgery is difficult like traditional open surgery, after completely blocking the renal arterial and venous blood supply, the method of adding ice chips around the part of the kidney to be preserved is used to cool dow...
