Inserter for the positioning of an intrauterine device

一种用于将宫内装置(管内装置)(40)放置入子宫内的插入器(10)，它包括一个柱塞(11)，一个连接于柱塞的把手(20)，一根用于移动管内装置的线(41)，一个锁定该线使得管内装置相对于柱塞保持不动的锁定装置，以及一个围绕柱塞的保护管(12)，其中保护管(12)相对于柱塞按这样的方式固定，即：该保护管能够以其进入子宫的前端被推动经过柱塞一段距离(L)，该距离基本对应于被组装用于插入的管内装置的长度。所述止动件(R1和R2)确保：在T形管内装置之横向构件的翼(42，43)的半球形末端(42a，43a)的一部分未被保护管(12)覆盖住而翼(42，43)仍保持相向压缩的状态下，保护管的前端(12a，朝向子宫)被停止。 PCT No. PCT/FI95/00666 Sec. 371 Date Jun. 2, 1997 Sec. 102(e) Date Jun. 2, 1997 PCT Filed Dec. 5, 1995 PCT Pub. No. WO96/18365 PCT Pub. Date Jun. 20, 1996An inserter for the positioning of an intrauterine device in the uterus, which inserter includes a plunger, a handle attached to the plunger, a string for the removal of the IUD, a locking device to lock the string in such a way that the IUD remains immobile in relation to the plunger, and a protective tube around the plunger. The protective tube is arranged in relation to the plunger in such a way that it can be pushed, at the forward end that goes into the uterus, past the plunger at distance (L) , which corresponds substantially to the length of the IUD assembled for insertion. The stop members ensure that the front edge of the protective tube is stopped in a configuration in which the hemispherical tips of the wings of the transverse member of a T-shaped IUD remain partly uncovered by the protective tube, but the wings nevertheless remain pressed against each other.
