Abstract
The utility model discloses an anastomat, which comprises a cylinder body portion and an umbrella head portion, wherein the umbrella head portion comprises a fixed end and an extensible umbrella leaf. The edges of the fixed end are hinged with the umbrella leaf, the middle portion in the internal fixed end is connected with a central connecting bar, a plurality of umbrella leaf push rods are arranged on the outer side of the central connecting bar, and the umbrella leaf push rods are slidingly connected with the inner side of the umbrella leaf, a suspended arm of a nail base is arranged on the edges of the inner side of the umbrella leaf, an anastomotic nail base is hung on the suspended arm of the nail base, the central connecting bar and the umbrella leaf push rods are all placed in the cylinder body portion, an anastomotic nail warehouse which is provide with the anastomotic nail is arranged on one end of the cylinder body portion which is close to one end of the umbrella leaf relatively to the suspended arm of nail base, the anastomotic nail warehouse is communicated with a channel, a guiding steel wire and an anastomotic nail jack are placed in the channel. The utility model is mainly used to the anatomosis of bladder and urinary during the operation of laparoscope or opening operation, which can solve the problems of low efficiency, difficult operation and favorable effect existing in the conventional suture anastomosis.
Description
Technical field
This utility model relates to a kind of bladder-urethra anastomosis device that is used for laparoscopic surgery and open surgery.
Background technology
Behind full bladder excision of peritoneoscope or the prostate radical excision, the identical of bladder-urethra is a committed step of operation, also is a difficult problem of operation.In the small space at the bottom of the basin, carry out coincideing of bladder-urethra, even all be suitable difficulty, and at present owing to lack relevant coinciding machine, cause problems such as identical inefficiency, operating difficulties, match result be not certain to solve in open surgery.
Summary of the invention
At the shortcoming of prior art, the purpose of this utility model provides a kind of anastomat, problems such as the inefficiency of bladder-urethra anastomosis, operating difficulties when solving peritoneoscope and open surgery.
To achieve these goals, the technical solution of the utility model is: a kind of anastomat, and it comprises tubular body and umbrella shape head; But the umbrella shape head comprises stiff end and hypertonic umbrella leaf, the edge of stiff end and umbrella leaf are hinged, the inboard middle part of stiff end is connected with a center linkage, outside center linkage, be provided with some umbrella leaf push rods, this umbrella leaf push rod and umbrella leaf inboard are slidingly connected, on the inboard limit of umbrella leaf, also be provided with nail seat suspension arm, be hung with the anastomosis staple seat at this nail seat suspension arm; Center linkage and umbrella leaf push rod all are placed in the tubular body, be provided with the identical nail bin of placement anastomosis staple near the corresponding nail seat of the end suspension arm of umbrella leaf at the tubular body, the nail bin that should coincide communicates with a passage, is placed with guiding steel wire and anastomosis staple push jack in this passage.
Umbrella leaf push rod is connected with the umbrella leaf by the slide block that is arranged in the inboard chute of umbrella leaf.
Umbrella leaf inboard above nail seat suspension arm also is provided with the cutting knife groove, is provided with cutting knife at described tubular body near an end correspondence of umbrella leaf.
Center linkage, umbrella leaf push rod and anastomosis staple push jack are equipped with the promotion handle.
Anastomosis staple and anastomosis staple seat are made for absorbing macromolecular material.
Anastomosis staple is a U type anastomosis staple, and head end has overhead kick, fixes automatically, do not get loose in insertion nail seat back.
Compared with prior art: the head of this utility model anastomat is umbrella, and per urethra is put into, and this head stretches into and is umbrella behind the bladder and opens, and bladder to urethra direction tractive, is coincide with urethra stump and bladder or for bladder; The tubular body is installed four pieces of U type anastomosis staples, after the use, can adorn anastomosis staple once more and reuse; After anastomosis staple passes tissue, will just in time pass the nail seat that hangs on the umbrella leaf, like this, what anastomosis staple was firm is fixed on the nail seat, promotes head forward, and nail seat and anastomosis staple are just taken from suspension arm, withdraw from anastomat and have just finished anastomosis procedures; And anastomosis staple and nail seat are made for absorbing macromolecular material, and tissue biocompatibility is better, can degrade in the set time.
