Body 1, excitation handle 2, center-pole 3, knob 4, ejector sleeve 5, pipeloop 6, sleeve 7, hangnail 8, connection frame 9, connecting rod 10 and block 11,
It is provided with excitation handle 2 below the outer surface of shell 1, and shell 1 is internally provided with center-pole 3, the right end of center-pole 3 runs through
Shell 1 is connected with knob 4, and the outer wall of center-pole 3 is equipped with ejector sleeve 5, and the left end of center-pole 3 is connected with pipeloop 6, sleeve 7
It is set to the inside of pipeloop 6, and the surrounding of pipeloop 6 is provided with hangnail 8, connection frame 9 is set to the left end of shell 1, and connects frame 9
Be internally provided with block 11, and block 11 is connected by connecting rod 10 with the inner wall for connecting frame 9；
The connection type of excitation handle 2 and shell 1 is hinged, and shell 1 is welding with the connection type for connecting frame 9, it is ensured that
The stability connected between shell 1 and connection frame 9, to ensure that the normal use of the stapler；
Ejector sleeve 5 and the connection type of pipeloop 6 are Nian Jie, and ejector sleeve 5 is rubber material, and ejector sleeve 5 and pipeloop 6 and shell 1
Center line is located along the same line, more stable when can making pipeloop 6 mobile in this way and rotation, further ensures the kiss
The use of clutch；
Sleeve 7 is an integral structure with pipeloop 6, and sleeve 7 and the connection type of center-pole 3 are is threadedly coupled, is convenient in this way pair
The disassembly of center-pole 3 offers convenience for the operation of user；
Hangnail 8 is angularly distributed in the surrounding of pipeloop 6, and pipeloop 6 is made of degradable biomaterial ellagic acid-chitosan, adopts
With degradable biomaterial, pipeloop 6 can be made voluntarily to degrade in patient's fitting, compared to the mode of traditional anastomosis staple, increased
The practicability of the stapler；
There are two the settings of block 11, and 2 blocks 11 are semicircle, and 2 blocks 11 are that rotation connects with connecting rod 10
Connect, in this way the stapler when not in use, pipeloop 6 can be protected, reduce bacterium infection.
Working principle: when using the degradable vesicourethral stapler, according to Fig. 1-3, user first holds shell
The end of body 1, then that connection frame 9 is inserted into the patient, then user's the other hand pushes knob 4, so that in the drive of knob 4
Core bar 3 and pipeloop 6 are slided from shell 1 from inside to outside together, when at the position that pipeloop 6 slides into block 11, because of block 11 and even
Extension bar 10 is rotation connection, therefore under thrust, and pipeloop 6, which can push block 11 open, to be continued to be displaced outwardly, until pipeloop 6 is moved to
It needs at identical tissue；
At this moment user hooks the open end of bladder by the hangnail 8 on pipeloop 6, and bladder body is pulled, when being pulled to
When the stump of urethra, then the stump of urethra is hooked with the hangnail 8 of 6 other side of pipeloop, just makes open end and the urethra of bladder in this way
Stump tense together, formed matching surface, user pins pipeloop 6 by auxiliary appliance later, and turning knob 4 makes knob 4
It drives center-pole 3 to rotate, is threadedly coupled because of center-pole 3 and the sleeve 7 inside pipeloop 6, therefore with the rotation of center-pole 3,
Center-pole 3 can be made to separate with sleeve 7, so that center-pole 3 be made to separate with pipeloop 6, then user will connect frame 9 from patient's body
It takes out, 6 pairs of pipeloop tissues is only stayed to carry out identical, pipeloop 6 is made of degradable biomaterial ellagic acid-chitosan, so can be with
The growth of previous anastomotic and degrade, be finally per urethram discharged, be the course of work of whole device above, and in this specification not
