固定式节育器放置器Fixed IUD Placer

本发明涉及医用器具，特别涉及宫内节育器(IUD)放置器的改进。The invention relates to a medical device, in particular to an improvement of an intrauterine device (IUD) placement device.

链状结构的固定式宫内节育器，是目前节育技术领域公认的一种具有良好节育效果且副作用少的节育器具，它是通过专用的放置装置将其前端固定在子宫底部的肌层中，使呈链状结构的节育器旋挂于子宫腔内，节育器上构成链状结构的铜环在宫腔内释放铜离子而发挥避孕作用，其突出的优点是对子宫壁的刺激小，因而副作用也小。但由于现有用于放置固定式宫内节育器的放置器存在着不易控制节育器前端插入子宫底部肌层的深度问题，致使此种节育器的应用受到影响。目前使用的固定式宫内节育器放置器，如ZL92227292专利申请中所披露的宫内节育器放置器，其插入子宫底部肌层的深度完全靠操作者的感觉和经验，缺乏有效的指示标志和控制办法，容易造成子宫穿孔、节育器固定不牢、不到位等问题，严重限制了固定式节育器的广泛使用。The fixed intrauterine device with a chain structure is currently recognized in the field of birth control technology as a birth control device with good birth control effect and few side effects. It uses a special placement device to fix its front end in the muscle layer of the bottom of the uterus. The chain-like structure of the IUD is hung in the uterine cavity, and the copper ring on the IUD that forms the chain structure releases copper ions in the uterine cavity to play a contraceptive effect. The side effects are also small. However, because the existing placer for placing the fixed intrauterine device has the problem that it is difficult to control the depth at which the front end of the IUD is inserted into the myometrium of the fundus of the uterus, the application of this IUD is affected. Currently used fixed IUD placement device, such as the IUD placement device disclosed in the ZL92227292 patent application, the depth of its insertion into the bottom muscle layer of the uterus depends entirely on the operator's feeling and experience, and lacks effective indicator marks and The control method easily causes problems such as uterine perforation, IUD fixation is not firm, and is not in place, which seriously limits the widespread use of fixed IUDs.

本发明的目的在于提供一种新型固定式节育器放置器，这种新型固定式节育器放置器能够严格控制固定式宫内节育器(如ZL92227292专利申请涉及的宫内节育器)插入子宫底部肌层的深度，确保固定式宫内节育器的固定部分植入子宫底肌层之中，提高固定式宫内节育器在子宫肌层的固定率，能有效防止传统放置器在操作中容易造成子宫穿孔、节育器固定不牢、不到位等问题，且放置操作简单易学，容易掌握，操作快捷，有利于固定式宫内节育器的推广使用。The purpose of the present invention is to provide a novel fixed IUD placer, which can strictly control the insertion of a fixed IUD (such as the IUD involved in the ZL92227292 patent application) into the fundus muscle of the uterus. The depth of the layer ensures that the fixed part of the fixed IUD is implanted in the myometrium, improves the fixation rate of the fixed IUD in the myometrium, and can effectively prevent the traditional placer from easily causing the uterus during operation. Problems such as perforation, weak fixation of the IUD, not in place, etc., and the placement operation is simple and easy to learn, easy to master, and quick to operate, which is conducive to the popularization and use of the fixed IUD.

When the 1 cm push rod 6 passing through the tail opening of theouter tube 5 is pressed, the front end of theplacement needle 2 is stretched from the inside of the outer tube Out of 1 cm, that is, in actual operation, the front end of theplacement needle 2 carries the fixed knot of the IUD and advances 1 cm into the myometrium. After the fork-shaped placement needle is withdrawn, the fixed knot of the IUD is left in the myometrium. Ahandle 13 is installed on the tail of the push rod 6 passing through the tail opening of theouter cylinder 5. Thehandle 13 is only for the comfort of the handle and the improvement of the appearance during operation, and does not affect the operation of the push rod 6 and theplacement needle 2. The advancing distance of time. There is a positioning block 14 made of slidable small pieces on the outside of the outer sleeve 1, and its function is to indicate the depth of the uterine cavity on the outer sleeve 1, so as to control the depth of the placer inserted into the uterine cavity during operation, so that it can be accurately placed. to the bottom of the uterus. The placement needle of the present invention is made of stainless steel, and the rest of the parts are made of non-toxic plastic materials.

使用时将固定式宫内节育器前端的固定结套在放置针顶端的叉状结构上，将尾部拉起，使固定式宫内节育器沿连接杆拉直，随后将尾丝固定线夹于夹线槽中，再将外套管及外筒、攀头固定连好后，从拉线孔将固定在夹线槽中的尾丝固定线的游离末端抽出至拉线孔外，套上柄头，以此种状态进行消毒处理后即可由专业医生使用。当外套管的顶端到达子宫底部时，用右手姆指推动柄头，此时固定结即进于子宫肌层内，再拉动位于拉线孔外面的尾丝固定线之游离末端，使其从夹线槽中脱出，然后松开右手姆指，已经进入子宫肌层的放置针前部由于张力弹簧的回位而自动退缩，并与插入子宫肌层内的节育器固定结分离，将固定结留置在子宫肌层内1厘米深处，当放置针前端重新回到外套管内后，缓慢退出放置器，此即完成固定式宫内节育器的放置。When in use, put the fixed knot at the front end of the fixed IUD on the fork-shaped structure at the top of the needle, pull up the tail to make the fixed IUD straight along the connecting rod, and then clip the tail silk fixing wire on the In the clamping groove, after fixing and connecting the outer casing, the outer cylinder and the climbing head, pull out the free end of the tail wire fixed wire fixed in the clamping groove from the cable hole to the outside of the cable hole, put the handle on it, and In this state, it can be used by professional doctors after disinfection. When the top of the outer cannula reaches the bottom of the uterus, push the handle with the thumb of your right hand. At this time, the fixed knot enters the myometrium, and then pulls the free end of the tail wire fixed wire outside the pull wire hole to make it from the clip wire. Then release the thumb of the right hand. The front part of the placement needle that has entered the myometrium will retract automatically due to the return of the tension spring, and will be separated from the fixed knot of the IUD inserted into the myometrium, and the fixed knot will be left in the At a depth of 1 cm in the myometrium, when the front end of the placement needle returns to the outer cannula, slowly withdraw from the placement device, and the placement of the fixed IUD is completed.
