Description
Technical field
This utility model relates to bio-medical instrument field, especially relates to a kind of super-elasticity basket type induced abortion device.
Background technology
Various big hospital adds anaesthetic carrying out vacuum aspiration when at present, the most so-called painless abortion, although solving misery and the psychentonia problem of operation, but not solving the variety of problems of vacuum aspiration, during such as operation, needing negative pressure and cervix dilating；Negative-pressure suction pipe is stereoplasm tube tool, and stereoplasm tube tool is inserted after cervix dilating mouth uterine cavity could carry out suction scrape gestation thing, and stereoplasm tube tool can not comply with the change in the orientation in uterus and curvature, the perforation of uterus etc..For many years in order to improve the safety of operation, effectiveness, minimizing operation pain and complication, Chinese scholars has carried out many research and improvement to it, but all without departing from this ultimate principle of vacuum suction, therefore also fail to fundamentally avoid by series of side effects produced by vacuum suction and complication.
Utility model content
This utility model is to solve the problem arrived set forth above, a kind of super-elasticity basket type induced abortion device is provided for this, including sheath pipe, seal wire, basket and handle, it is divided into front end seal wire and rear end seal wire through the seal wire within sheath pipe, described handle is connected with rear end seal wire, being connected with front end seal wire for removing the basket of pregnant tissue, described basket includes some wire rings, and described basket is made by super-elastic shape memory alloy.
As preferably, described basket is made by nitinol alloy wire.
As preferably, the shape of cross section of described wire ring is arranged to circular or square.
As preferably, described seal wire outer surface is smooth setting, is coated with floor height molecular film or a politef above.
As preferably, described basket is without point basket.
The beneficial effects of the utility model are: this utility model reasonable in design, can be with the purpose of minimum injury termination of pregnancy, induced abortion device profile has the biggest elasticity and little coefficient of friction, patient can be made inserting and take out when easily to stand, and the change in orientation, uterus and curvature can be complied with, induced abortion device certain flexibility and non-adhesion simultaneously, not produce new wound to operation receiveing person taking out when, there is good biocompatibility, avirulence, uterus uterine cavity wall will not be caused infection and injury, do not result in the perforation of uterus, pregnant tissue is all taken out, reduce operation receiveing person painful.

This utility model will illustrate by example and with reference to the appended drawing, wherein:
Fig. 1 is schematic perspective view of the present utility model；
Fig. 2 is schematic front view of the present utility model；
In figure: 1, sheath pipe；2, seal wire；2.1, front end seal wire；2.2, rear end seal wire；3, basket；3.1, wire ring；4, handle.
Detailed description of the invention
All features disclosed in this specification, or disclosed all methods or during step, in addition to mutually exclusive feature and/or step, all can combine by any way.
Any feature disclosed in this specification (including any accessory claim, summary and accompanying drawing), unless specifically stated otherwise, all can be by other equivalences or there is the alternative features of similar purpose replaced.I.e., unless specifically stated otherwise, an example during each feature is a series of equivalence or similar characteristics.
A kind of super-elasticity basket type induced abortion device as depicted in figs. 1 and 2, including sheath pipe 1, seal wire 2, basket 3 and handle 4, it is divided into front end seal wire 2.1 and rear end seal wire 2.2 through the seal wire 2 within sheath pipe 1, described handle 4 is connected with rear end seal wire 2.2, it is connected with front end seal wire 2.1 for removing the basket 3 of pregnant tissue, described basket 3 includes that some wire rings 3.1, described basket 3 are made by super-elastic shape memory alloy.
Described basket 3 is to be made by the nitinol alloy wire of 0.2～1mm.
The shape of cross section of described wire ring is arranged to circular or square.
Described seal wire 2 outer surface is smooth setting, is coated with floor height molecular film or a politef above.
Described basket 3 is without point basket.
Described sheath pipe 1 is arranged to cylindrical soft tubule.
In use, the basket of super-elasticity basket type induced abortion device and seal wire could be arranged to the parts that integrated disposable sterilization is standby, execute preoperative, by seal wire rear end from the front end of sheath pipe through to the rear end stretching out sheath pipe, handle is installed on seal wire rear end, overall disinfection；nullWhen executing art，The position of anemia of pregnant woman、Sterilization、Drape、Expose cervix uteri and check all identical with uterine aspiration with cervix uteri，The hand-held handle of operator one (handle can connect electric rotating motivation and can also directly operate)，The front end of one hand-held sheath pipe，After the front end of sheath pipe is placed in uterine cavity mouth，It is sent to slowly in uterine cavity，Now，One hand-held handle，One hand-held sheath pipe，Basket is controlled by controlling the handle of seal wire rear end，First basket is stretched out in sheath pipe，Now add due to the super-elasticity of Nitinol and do not restricted by sheath pipe，The profile that basket is expanded to preset extension by contraction state slides in uterine cavity smoothly，Present basket shape，Super-elasticity behavior due to Nitinol，Now basket and uterine cavity wall are Elastic Contact，Operator can be according to the bottom of feel sensation uterine cavity，Under the monitoring in real time of supersonic sounding instrument, basket can also be placed in pregnant Nang Suochu，It is wrapped in basket，By rotary handle thus pregnant capsule is cut from uterine cavity wall under stripping，Then toward the handle of seal wire rear end of pulling back，Part basket is made to enter in sheath pipe，Thus reach being wrapped in basket by pregnant capsule tightly，Prevent it from slipping，While quick rotation seal wire rear end handle and extracted，Lens capsule tissue of whether being pregnant in seeing it by pull-out basket sees whether to reach the purpose of termination of pregnancy，Or watch under the detection of supersonic sounding instrument and the most pregnant capsule and Placenta Hominis all being taken out；If no, can again by basket as in uterine cavity, rotary handle again, feel the when that uterine cavity wall being relatively rough, then uterine cavity is the cleanest, has i.e. reached the purpose of termination of pregnancy.
This utility model reasonable in design, can be with the purpose of minimum injury termination of pregnancy, induced abortion device profile has the biggest elasticity and little coefficient of friction, patient can be made inserting and take out when easily to stand, and the change in orientation, uterus and curvature can be complied with, induced abortion device certain flexibility and non-adhesion simultaneously, not produce new wound to operation receiveing person taking out when, there is good biocompatibility, avirulence, uterus uterine cavity wall will not be caused infection and injury, do not result in the perforation of uterus, pregnant tissue is all taken out, reduce operation receiveing person painful.
This utility model is not limited to aforesaid detailed description of the invention.This utility model expands to any new feature disclosed in this manual or any new combination, and the arbitrary new method that discloses or the step of process or any new combination.
