Description
Technical field
The present invention relates to the field of peritomizing, and in particular to a kind of prepuce cutting stitching instrument and its U screw top pin.
Background technology
Redundant prepuce or phimosis are one of roots of male urinary system infection and sexually transmitted disease.Redundant prepuce or bag
Stem can cause urinary tract infection to cause chronic prostatitis, it may appear that have a pain in the back, a series of symptoms such as impotence and premature ejaculation, because
This, it is to prevent one of good measure of these illnesss to remove long foreskin.
Traditionally, using phimosis or long foreskin is surgically removed, technical essential is the unnecessary foreskin of excision, stopped
Blood and incisxal edge skin apposition suture.Postoperative patient can not walk about, and also bear when often changing a medicine all hurt like hell to last take out stitches
By great pain, hemostasis by ligation in addition can thoroughly not cause foreskin hemotoncus, then need surgical procedure again.Further, since excision bag
Skin and hemostasis are performed separately, and extend operating time, exacerbate the Psychological phobia of patient.
It has developed at present and laser and electric knife technology be applied to the treatment method peritomized, though the treatment method
So it instead of scissors cut and blutpunkte can be solidified.But this treatment method meeting burn patient tissue, and easy infection.
This area have developed prepuce circumcision device again therewith, foreskin otch be sutured using suturing nail/U nails, this kind
Ring cutting device mainly includes built-in and two kinds of eversion type, the existing patent application before this area, but deposits in the prior art
In following technical problem：
(1) thimble and U nails are likely to be at the state that does not position completely in static state, U nails in nail groove not straight up
But in the state of deviation nail groove side inwall；
(2) when thimble and U nails are in dynamic, between the vibrations of prepuce cutting stitching instrument in itself, and thimble and U nails
Contact/collision/synchronizing moving is not substantially vertical upward when may cause U nails to move forward；
(3) if U nails do not get nail groove by thimble straight up, its through foreskin or its hetero-organization or with U nail anvils seat/U
When nail seat carries out juxtaposition metamorphose, in askew/oblique state；
(4) U nail can not forward direction get will cause U nail closure not exclusively in addition closure failure, lead to not accurately close blood
Pipe, gently then causes bleeding, serious meeting causes nailing position deviation, it is impossible to effectively suture；
(5) even occur the deformation of U nails, U nails in the implementation process of some bum prepuce cutting stitching instruments to fail
Squeeze into desired location or even hammer into blood vessel, cause operative failure and patient's considerable distress.
The content of the invention
For above prior art problem, it is an object of the invention to provide a kind of improved prepuce cutting stitching instrument and its
U screw top pins, its by the improvement to U screw top pins, make its with U the no matter static dynamic of nail can good location coordinate, nailing is accurate,
Success rate of operation is high, and concrete technical scheme is as follows：
A kind of U screw tops pin, including thimble body and thimble positioner, the thimble positioner are arranged at thimble body
One end termination, the thimble positioner includes the positioning table of recessed locating slot and/or projection, the recessed positioning
