Roeder knot anastomat, prefabricated Roeder knot knotting device and automatic knotting method of prefabricated Roeder knot knotting device

Abstract

The invention proposes a Roeder knot anastomat, the prefabricated Roeder knot knotting device and the automatic knotting method of the prefabricated Roeder knot knotting device, the Roeder knot anastomat is matched with the prefabricated Roeder knot, knotting operation of a doctor in the operation anastomosis process is omitted in the operation process, rapid and efficient anastomosis is achieved,and the operation time is greatly shortened. The prefabricated Roeder knot is wide in application range, can be applied to suture of a renal pelvis and a ureter, and can also be applied to operationsneeding to use needles and threads for suture. The Roeder knot anastomat is simple in structure, easy to operate, capable of being recycled, economical and high in practicability. According to the prefabricated Roeder knot knotting device, through a series of operation steps, knotting of the prefabricated Roeder knots on the winding post can be automatically achieved, so that large-batch factoryproduction of the winding post wound with the prefabricated Roeder knots is achieved, the winding efficiency is high, and a large amount of labor cost is reduced.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a Luther knot stapler, a prefabricated Luther knot knotting device and an automatic knotting method thereof. Background technique [0002] In the reanastomosis of pyelonephroma and ureteropelvis for congenital hydronephrosis, manual needle and thread anastomosis is required for the anastomosis of ureter and renal pelvis, whether it is laparoscopic surgery or open surgery. In the manual suture process, in order to prevent the suture from loosening, each knot needs to be composed of three single structures, which is the longest link in the operation process and an important determinant of the duration of anesthesia. Reducing the duration of anesthesia can reduce its impact on the patient's brain or nervous system. [0003] In addition, the knotting step in the surgical anastomosis process is repetitive labor, which requires more proficiency of the operating doctor. Doct...

Problems solved by technology

Invention patent: CN102626331B proposes a lasso knotter, which has a simple structure and is easy to operate. Each operation can form a lasso knot, but the scope of application of the knotter is narrow, and it is only suitable for occasions that require lasso knots And the lasso knot itself has a simple structure

In the process of surgical anastomosis, at least three single knots need to be used for each knot, so the lasso knotter is not suitable
