Abstract
The invention provides an intrauterine device adaptive to various uterine cavities. A body is made of traditional materials such as nickel titanium memory alloy wires, stainless steel wires, metal copper wires, medicine and soft elastic materials like silicone rubber. According to the shape of the body, two longitudinal arms and two horizontal arms are included, the lower ends of the two longitudinal arms are connected in a U shape, the upper ends of the two longitudinal arms are connected with the two horizontal arms to the left side and the right side respectively, and the two ends of the two horizontal arms are designed to be end heads which are made of the soft elastic materials and are of a tooth-shaped structure. According to the design, the suitability of the intrauterine device and a uterine cavity is increased, and intrauterine device displacement and falling off can be effectively avoided.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, be specifically related to a kind of intrauterine device that adapts to multiple uterine cavity.
Background technology
The intrauterine device shape and the kind that use at present have a lot, though can play certain contraceptive effect, still exist in actual use following two problems to be not yet resolved.The one, the gauge size of intrauterine device is relatively fixing, but between individuality, uterine cavity shape and difference in size are larger, the method that there is no clinically is accurately measured uterine cavity shape and size, cause the intrauterine device of current placement and the suitability of uterine cavity poor, cause intrauterine device displacement to occur and come off to cause placing unsuccessfully.The 2nd, the most of hard materials such as rustless steel, plastics that adopt of intrauterine device are made, deformability is poor, and the easypro contracting that can not adapt to uterus changes, and easily cavity of uterus is caused to mechanical stimulus, cause the side reactions such as the hemorrhage even perforation of uterus of pain, bring misery and somatic damage to operation receiveing person.
Summary of the invention
The invention provides a kind of intrauterine device that adapts to multiple uterine cavity.Can address the above problem.
The invention provides a kind of intrauterine device that adapts to multiple uterine cavity, its main body adopts Ultimum Ti silk, stainless steel silk, and metal copper wire, medicine and soft elastic material are made as traditional materials such as silicone rubber.Its body shape is two trailing arms and two transverse arms, and two trailing arm lower ends adopt " U " type to connect, and two trailing arm upper end difference are connected with two transverse arms both sides to the left and right, are designed to the termination with dentalation that soft elastic material is made at the two ends of two transverse arms.
The version of intrauterine device provided by the invention meets uterus shape, and two trailing arms are placed in uterine cavity centre, has the elasticity of trend both sides cornua uteri direction.Under normal condition, be applicable to maximum fundus of uterus width.In the time that fundus of uterus reduces due to interindividual variation or uterine contraction width, transverse arm two ends are under pressure and drive two inside resiliences of trailing arm, thereby the distance between two trailing arms reduces the even width of juxtaposition minimizing transverse arm, with the fundus of uterus width of Adaptive change, and can make the end of two transverse arms remain at the position of both sides cornua uteri.This design has increased the suitability of intrauterine device and uterine cavity, effectively avoids intrauterine device displacement occurs and come off.
Intrauterine device transverse arm provided by the invention two ends are designed to the termination of dentalation, and employing and the good soft elastic material of human compatibility are as silicone rubber manufacture.Transverse arm two ends are intrauterine device support zones in uterine cavity, and the soft durometer of soft elastic material and endometrial cavity is close, can Uterus wall not caused and be stimulated and damage.Dentalation design forms Multi-contact with Uterus wall, strengthen the contact area of this position and Uterus wall and can when stressed, produce elastic deformation, having overcome general birth control apparatus and adopted some contact support to cause the hemorrhage situation that even causes perforation of uterus damage of the excessive pain causing of contact site local pressure.This dentalation is designed to right-angle side to uterus center position simultaneously, is designed to hypotenuse to cornua uteri direction, when this structural design can be relaxed in uterus contracting motion, makes transverse arm trend towards both sides cornua uteri and moves, and further reduces coming off of intrauterine device.

Fig. 2 is a kind of deformation schematic diagram of the intrauterine device that adapts to multiple uterine cavity.
Detailed description of the invention
As shown in Figure 1, a kind of intrauterine device that adapts to multiple uterine cavity provided by the invention, its main body adopts Ultimum Ti silk, stainless steel silk, metal copper wire, medicine and soft elastic material are made as traditional materials such as silicone rubber.Its body shape is two trailing arms 1 and two transverse arms 2, two trailing arm 1 lower ends adopt " U " type to connect, two trailing arm 1 upper end difference are connected with two transverse arms 2 both sides to the left and right, are designed to the termination with dentalation 3 that soft elastic material is made at the two ends of two transverse arms 2.
As shown in Figure 2, a kind of intrauterine device that adapts to multiple uterine cavity provided by the invention, it presents shape 4 under normal condition, under transverse arm stress, deformation occurs, and can present shape 5.The transverse arm width of shape 5 is obviously less compared with shape 4, fundus of uterus width that can Adaptive change, and can make the end of two transverse arms remain at the position of both sides cornua uteri.
As shown in Figure 1, the design of unique dentalation is made and had in termination 3 by soft elastic material as silicone rubber, and the soft durometer of soft elastic material and endometrial cavity is close, can Uterus wall do not caused and be stimulated and damage.Dentalation design forms Multi-contact with Uterus wall, strengthen the contact area of this position and Uterus wall and can when stressed, produce elastic deformation, having overcome general birth control apparatus and adopted some contact to support the hemorrhage situation that even causes cornua uteri puncture injury of the excessive pain causing of contact site local pressure that causes.Dentalation is designed to right-angle side to uterus center position, is designed to hypotenuse to cornua uteri direction, when this structural design can be relaxed in uterus contracting motion, makes transverse arm trend towards both sides cornua uteri and moves, and can further reduce coming off of intrauterine device.
A kind of intrauterine device that adapts to multiple uterine cavity provided by the invention, its main body can adopt Ultimum Ti silk as skeleton, is wound around copper wire layer on skeleton, and copper wire layer outside is wound around stainless steel silk layer and makes.In the soft elastic material of termination, can load contraception or anti-inflammatory analgesic class medicine.
Claims (2)
1. one kind adapts to the intrauterine device of multiple uterine cavity, it is characterized in that body shape is two trailing arms 1 and two transverse arms 2, two trailing arm 1 lower ends adopt " U " type to connect, two trailing arm 1 upper end difference are connected with two transverse arms 2 both sides to the left and right, have the termination 3 that soft elastic material is made at the two ends of two transverse arms 2.
2. a kind of intrauterine device that adapts to multiple uterine cavity according to claim 1, is characterized in that described termination 3 has dentalation design.
