Description

The instrument and its method in intrauterine contraceptive device are inserted for postpartum

This application claims the provisional application for the India bearing series No.2534/MUM/2013 that on 08 01st, 2013 submits Priority.

Technical field

The present invention relates to after a kind of childbirth soon intrauterine insert the intrauterine contraceptive device (being abbreviated as IUD) instrument and The postpartum insertion of its method, medically known as IUD.

Background technology

The research for being implanted into the intrauterine contraceptive device on postpartum is agreed with placing the intrauterine contraceptive device soon after childbirth (IUD)； Because vagina, cervix and uterus are extended, this makes placement easy.Although postpartum insertion IUD's is particularly advantageous in that it is nothing Pain, bled and without obstruction lactation, another society and the free-revving engine economically of postpartum insertion without result in extra For because IUD is placed at once in postpartum, women need not arrive hospital/sanatorium again and go to a doctor to insert IUD.Because Contraceptive device is not used actively in the women of some developing countries.

In the past, many principles related to postpartum IUD insertions are obtained.Patent No.US4721105 illustrates to be used to produce Place IUD inserter in uterine cavity immediately afterwards.The device includes two inside and outside cylindrical bars, and the cylinder is by means of locking Component is with being engaged with each other.Pin is attached to IUD.The pin helps IUD to be attached to uterine cavity.By using interior bar on the process nature Push away it to promote pin, and the fundus of uterus may be caused excessively to be punctured.

Patent No.US3954103 discloses a kind of for manually placing intrauterine contraception in uterus immediately after giving a birth The inserter of device；This needs doctor's handle to be manually placed into uterine cavity and use pin fixing equipment.Placement IUD method is unhygienic simultaneously And high skill is required, therefore be dangerous.

Another prior art, patent No.US5303717 illustrates a kind of be used in the intrauterine fixation intrauterine contraceptive device Device, the device includes being attached to the non-biodegradable screw thread of contraceptive device, and the device is connected to holding member, the guarantor Hold component to be made up of the biodegradable material for helping to be attached to the postpartum state in uterus, and recover normal condition in uterus Dissolve at leisure afterwards.IUD is also attached in uterus by this method using pin, and it is excessive risk and pain to cause it.

It is common and it is well known that many surgeons are used as postpartum using drill with ferrule bar cramp (Kelly clip) or placental forceps The equipment of insertion, because the size in uterus is large enough to accommodate the big handle of drill with ferrule bar cramp.The process needs each sterilization.Together , there is the possibility that IUD is inadequately fallen down in sample.Additionally, there are the movement due to careless slip or hand, these operating theater instruments can The possibility of the damage to tender body part can be caused.

Therefore, this be used for postpartum insert at once IUD art methods and equipment have been considered to insert IUD when its It is not enough in the satisfaction of easiness, health and safety.

The postpartum size in uterus is sufficiently large, and is likely to IUD and is placed with its arm on non-horizontal surface.Except expertly Outside drill with ferrule bar cramp etc., the IUD quilts under postpartum state are pointed out or ensured to usually not known method/equipment from outside It is placed on specific direction.

Our invention overcomes these problems.

The purpose of the present invention

It is an object of the invention to provide a kind of work that the intrauterine contraceptive device (IUD) is wholesomely inserted under the postpartum state of uterus Tool.

Another purpose is that invention is a kind of inserts the intrauterine contraceptive device (IUD) under the postpartum state in uterus in specific direction Simple tool.

A further object of the present invention is to provide a kind of IUD inserters, and the IUD inserters can soon be used in postpartum, because This does not need women to be gone to a doctor again to be implanted into the intrauterine contraceptive device (IUD).

The content of the invention

Our invention is a kind of instrument that the intrauterine contraceptive device (IUD) is inserted for postpartum.Instrument is by flexible hard long tube Constitute, the hard long tube of flexibility and IUD are placed in cardinal extremity with identical shape and specific direction, the specific direction is relative to lying low The horizontal direction in the uterus of women, and IUD requirements are maintained at intrauterine.The direction can be dashed forward by the correlation in handle end Go out portion to be ensured that.This ensure IUD be not inserted into non-horizontal directions, otherwise due to postpartum uterus expansion size this be possible 's.The instrument is packaged in the bag with translucent cover, and is finally sterilized.

The specific direction of the IUD is kept by being arranged on multiple grooves of the cardinal extremity of bendable hard tube, while suture is from handle End is firmly held.Groove is either integrally provided the cardinal extremity or alternatively and optionally of bendable hard tube, by The bottom of bendable hard tube is installed by the extention of entitled directional head.

As another embodiment, specific direction does not have groove to be also maintainable, by being firmly grasped by from bendable hard tube The suture emerged, and/or by the way that suture is securely engaged with object of reference, or by the way that thread entanglement is locked into seam in slit Line.The slit or integrally in bendable hard tube or in the extention on bendable hard tube.

The length of bendable hard tube is that, when its cardinal extremity is close to the fundus of uterus, its handle end is through the postpartum uterus and expansion expanded Uterine neck from vagina protrude.IUD is equipped with suture corresponding with the length of bendable hard tube to protrude rational from handle end Length.Bendable hard tube is made up of the thermoplastic with material property and thickness, so that it being capable of slight curvature and such as need That wants takes required bending in insertion；Simultaneously it be sufficiently rigid and during insertion will not warpage and make IUD midway Fall down.

In order to perform the process of insertion, bag is partially opened and the bendable hard tube together with being placed in IUD is extracted out from bag. Bendable hard tube is held from handle end together with the suture for being kept tension, and IUD is sent in postpartum uterus.By checking Protuberance and/or object of reference, IUD specific direction is maintainable.The fundus of uterus of uterine cavity is perceived and is pressed from outside To drive and prevent in intrauterine IUD, and suture is released and bendable hard tube is extracted, and leaves IUD in intrauterine. In whole process, surgeon does not operate IUD directly.Thus, the process is hygienic.

Embodiment

Be described in detail referring now to accompanying drawing is used for the novel work in insertion intrauterine contraceptive device in postpartum according to the present invention The preferred embodiment of tool and its method.Here the term and statement used, which is merely illustrative, to be not used to limit.

Bendable hard tube 14 is included according to the instrument 10 of the present invention, and IUD30 is placed in same shape and with specific direction The cardinal extremity 18 of bendable hard tube 14, and require to be maintained at intrauterine, specific direction is relative to the uterus for the women that lies low Horizontal direction.

Bendable hard tube 14 have length 20 cause when cardinal extremity 18 is close to the fundus of uterus 49 handle end 17 through postpartum uterus and The cervix protrusion of expansion is outside vagina.

Multiple grooves 42 are selectively disposed in the cardinal extremity 18 of bendable hard tube 14, it is ensured that when suture is protected securely from handle end 17 IUD30 keeps direction when holding.Multiple grooves 42 have round edge and convergent opening, are easy to bendable hard tube 14 to injure and enter uterus smallly 50.Relation setting in the protuberance 44 of handle end 17 by means of mark, line or groove to be limited with groove 42 so that from handle end 17 determination IUD30 specific direction is possibly realized.Groove 42 or be integrally provided bendable hard tube 14 cardinal extremity 18 or, can Selection of land and optionally, by the extention that entitled directional head 45 is installed in the cardinal extremity 18 of bendable hard tube 14.

As another embodiment, specific direction can also be emitted by the handle end 17 being firmly grasped by from bendable hard tube 14 The suture 15 that goes out and/or locked by the way that suture 15 is securely engaged with object of reference 31, or by the way that suture 15 is wrapped in slit 46 Determine suture and be kept.Slit 46 or integrally in bendable hard tube 14 either additional on bendable hard tube 14 In part.

Object of reference 31 is substantially the non-circular component with appropriate handle, has hole 31A at center so as to which it is can Sliding and being snugly fitted on bendable hard tube 14 on curved hard tube will not rotate freely through so as to once install it.Because its is non- It is round-shaped, it as with reference to determine its on bendable hard tube 14 it is any mark or protuberance Angle Position.

IUD30 is equipped with suture 15 corresponding with the length 20 of bendable hard tube 14, so that the suture 15 of suitable length is dashed forward Handle end 17 is crossed in excess of export.This substantially also refers to the suture that the suture 15 is substantially used than the IUD under normally i.e. non-postpartum status It is long.In other words, it is provided with the suture 15 matched with IUD.

Bendable hard tube 14 is made up of the thermoplastic with material property and thickness 19, so that it can axially slightly Bending, as shown in figure 3, and because the shape in uterus 50 needs, the bending 16 of requirement is taken in insertion.

Although bendable hard tube 14 is flexible, it has length 20, and the length 20 is significantly greater than the applicable length of normal uterus Degree.Therefore, it is not excessively soft and with enough hardness, thus carry IUD30 until the fundus of uterus 49 and IUD30 will not in It is important that way, which is fallen down,.Meanwhile, bendable hard tube 14 should not be under due to the issuable back pressure of the resistance of cervix or uterine wall Bending.Therefore the thickness 19 of bendable hard tube 14 must be the property of the material of thermoplastic correspondingly optimal and with selection Matter is relevant.Typically, for high density polyethylene (HDPE), polypropylene or equivalent material, the order of thickness is 0.5 to 2.5mm.Principle On, the toughness of thermoplastic of the thickness with selecting is inversely proportional.

Stated differently, since it is bendable hard tube 14 that the shape and size in the postpartum of uterus 50, pliability and hardness, which are optimized, Importance, so as to bendable hard tube 14, rigidly (rigidly) carries IUD30 until the fundus of uterus 49.

Instrument 10 is sealed in bag and is finally sterilized, so that as the full envelope in the bag 35 with translucent cover 39 Enclosed equipment 25.

On the process of insertion, the base portion 36 of translucent cover 39 and bag 35 is partially separated.Can by being held from handle end 17 Curved hard tube 14, instrument 10 is taken out from transparent bag 35.Continue to hold bendable hard tube 14 and in handle by using a palm 41 The suture 15 at 17 is held, as shown in figure 5, instrument 10 is inserted in uterus 50 from cardinal extremity 18.Suture 15 keeps being tightened up.Due to expanding Vagina, cervix and the big opening in uterus, IUD30 size is unessential, and its normally be non-postpartum status under It is very important.IUD30 is carried in the uterine cavity of expansion until surgeon feels that IUD30 touches the fundus of uterus 49. IUD30 specific direction is maintained by noticing protuberance 44 and/or object of reference 31.

Uterine cavity, from external sensation, is pressed from outside with palm 40 by another palm 40 and IUD30 is utilized in abdomen Any important finger 40a in portion is forced to, as shown in Figure 5.The IUD30 driven from outside is kept as described above, this moment, Suture 15 is released at the handle end 17 of bendable hard tube 14 from palm 41 and/or object of reference 31 or slit 46；Then bendable Hard tube 14 is extracted little by little and safely.

Fig. 6 is shown in the IUD30 in the fundus of uterus, and Fig. 7 shows the IUD30 for being suitably disposed the fundus of uterus 50.

In most of figure, the intrauterine contraceptive device IUD of Common Shape " T " is displayed to describe the process, however, this sets It is standby to be applied to other similar and associated shape the various intrauterine contraceptive devices with process.

In order to ensure IUD30 specific direction, groove 42 and one or more protuberances 44 are set.Protuberance 44 is in hand It can be clearly seen at pommel 17, therefore surgeon ensure that bendable hard tube 14 is booked so as to which IUD30 is in water In plane.

The specific direction can also be obtained by setting and being manually directed to the object of reference 31 related to groove 42.

The specific direction can also be obtained without groove, be emerged by the handle end 17 being firmly grasped by from bendable hard tube 14 Suture 15, and/or by the way that suture 15 is securely engaged with object of reference 31.When through the object of reference 31 as shown in Fig. 1,2A, 2B When, suture 15 is securely engaged and tightly kept.Thus, IUD30 is forced to and not rotated arbitrarily, therefore maintains specific Direction.

The specific direction can also be obtained without groove, be emerged by the handle end 17 being firmly grasped by from bendable hard tube 14 Suture 15, lock suture 15 by the way that suture 15 is wrapped in slit 46.Slit 46 is one with bendable hard tube 14 The overall extention either on bendable hard tube 14.Thus, IUD30 is forced to and not rotated arbitrarily, therefore protects Hold specific direction.

Suture 15 engages with slit 46 or with object of reference 31 or is used as any other method of limiting mode, Suture 15 is also used as guiding to determine IUD30 direction.

Without groove or using the groove of variously-shaped and size, IUD specific direction can be by various possible methods Suture is firmly held from handle end to be maintained.
