Abstract
The utility model provides a birth-controlling device with a recoverable and switch type spermatic duct, which is provided with a stainless steel outer sleeve (1) and a device heart (2). A side hole arranged at the middle part of the device heart is communicated with one end, and is not communicated with the other end. A silica gel sealing ring (3) is arranged between the device heart and the outer sleeve. The side hole of the device heart is closed or opened by the displacement of the device heart. Thus, the birth-controlling device can be respectively closed and opened. The birth-controlling device is characterized in that the birth-controlling device is made of stainless steel which is nontoxic and innocuous for human bodies and medical human body silicon rubber. The contraception effect is reliable. The outstanding characteristic of the birth-controlling device is that the birth-controlling device needs no exciding for taking off and anastomosis when re-communicating, a switch of the birth-controlling device can be opened by spermatic duct centesis, and the purpose of re-communicating and re-birth can be obtained with an easy method. When needed contraception after re-birth, the birth-controlling device can be reused.
Description
The present invention is a kind of switching regulator deferent duct birth control apparatus, is a kind of birth control device of recoverability, can reuse again after educating again.
No matter the male contraception art is vasoligation, or the deferent duct gluing and stoping method, makes anastomosis educating Shi Junxu again.The vasovasostomy specification requirement is higher, is difficult to penetration and promotion at different medical unit.In order to remove the birth control operation receiveing person trouble and worry that the postfactor woman meets accident of performing the operation, especially develop into few children person's present stage by many children person China birth control operation receiveing person, developing a kind of deferent duct birth control device of safe and effective, recoverability, then is the common aspiration that vast birth control operation receiveing person looks forward to already.
In order to address this problem, Shanxi Zhao Sheng Cai Shi deferent duct bolt blocks up method, and Harbin Lv De Bin Shi rustless steel Embolization, also can reach recoverability, and bolt is logical again educates again but still the need incision is got.When needing birth control again after educating again, the birth control of need performing the operation once more again.
The purpose of this invention is to provide a kind of switching regulator deferent duct birth control apparatus.It not only can stop sperm to pass through effectively, reaches the contraception purpose; And can when educate again, both need not cut and get device, also as vasovasostomy, only need the skin deferent duct that punctures can open the birth control apparatus switch outward, reach again logical purpose of educating again, method is simple.After educating again, when still needing birth control, birth control apparatus can be closed, reach the purpose of using birth control apparatus once more with method.
This device adopts medical stainless steel and medical human silicone rubber to make, and is nontoxic to human body.Its specification has: long 5～7 millimeters, and 1.6 millimeters, 1.4 millimeters and 1.2 millimeters three kinds of external diameters.
Switching regulator deferent duct birth control apparatus structure is seen accompanying drawing 1 and accompanying drawing 2(profile).
Device with switchable spermatic duct for birth-controlling is achieved in that this device comprises an overcoat (1), and overcoat two ends (near, far-end) respectively has an opening, and a device heart (2) is arranged in the overcoat, and device in the heart section has a side opening, and side opening communicates with near-end, and does not communicate with far-end. Device heart far-end has an inclined-plane, and a silica gel sealing ring (3) is arranged between overcoat and the device heart. Be closed condition when contraceptive is in Fig. 1, sperm can not pass through; Be open state when contraceptive is in Fig. 2, at this moment, open smallest passage is 25～150 microns, and sperm can freely pass through smoothly.
The use of device with switchable spermatic duct for birth-controlling:
1, puts device art direct-view pincers and wear Faxian dew deferent duct, longitudinal incision deferent duct one osculum, behind the dilator expansion deferent duct, hold birth control apparatus and insert with holding device pincers from incision, then birth control apparatus is return about 2 millimeters of otch hypomere along in the pipe, the birth control apparatus middle part is on the otch, use " 1 " number silk thread ligation respectively in otch two ends birth control apparatus groove, to prevent that birth control apparatus from moving about, and the gap between energy complete closed birth control apparatus and the tube chamber, prevent sperm by with leak outside, improve contraceptive effect and avoid sperm antibody to form.
It should be noted that: before the art birth control apparatus is in closed condition; Nearly far-end is not turned over when putting device.
2, the reopening operation near-end apart from about 2 centimeters of birth control apparatus with the deferent duct that punctures outside the 5 1/2 indenting ball skins.After puncturing successfully, along finding the birth control apparatus proximal openings in the pipe, the metal sense of colliding is arranged this moment, indenting ball is inserted opening, firmly be pushed to forward slightly firmly can not promote till.This moment, the birth control apparatus switch was beaten " opening ".Make seminal vesicle perfusion (right side Congo red then; The left side is U.S. blue).During perfusion, local no swelling sense, and the operation receiveing person has micturition desire, and postoperative is urinated in observing and can be judged whether to lead to again.
3, use once more in the time of still need continuing to practise contraception after educating again, far-end apart from birth control apparatus about 2 centimeters deferent duct that punctures outside the near-end skin, with colluding method again birth control apparatus is closed, once more birth control.
Claims (2)
1, switching regulator deferent duct birth control apparatus, respectively there is a hole at these device two ends, and a device heart (2) that can two ends moves is arranged in this birth control apparatus, device in the heart portion one side opening is arranged, it is characterized in that side opening communicates with near-end, and do not communicate with far-end.Device heart far-end has an inclined-plane.
2, device according to claim 1 is characterized in that a silica gel sealing ring (3) is arranged between the overcoat (1) and the device heart (2).Move displacement by the device heart (2) two ends, make device heart side opening close or open.Thereby realize closing or opening of birth control apparatus.
