Abstract
The utility model provides a fixing clamp for an amniotic cavity puncture needle. The fixing clamp comprises an upper clamping piece, a lower clamping piece hinged with each other, and an elastic clamping component, and has the characteristics that the clamping parts of the upper clamping piece and the lower clamping piece all are slice-shaped, the opposite internal edges of the clamping part of the lower clamping piece and the clamping part of the upper clamping piece are symmetrically and respectively provided with a notch, so that the fixing clamp can fix the puncture needle, is convenient to operate, and can prevent injury.
Description
Technical field
This utility model belongs to the curable product technical field, relates to a kind of obstetrics operation special product, is a kind of amniocentesis pin fixation clamp specifically.
Background technology
At present, the amniocentesis technology that obstetrics adopt is widely used, and for example polyhydramnios needs the water of putting sheep out to pasture that punctures; Prenatal Screening excessive risk anemia of pregnant woman need extract amniotic fluid and do fetal cell inspection etc.When amniocentesis was put sheep out to pasture water or extraction amniotic fluid, the operative doctor right hand was held lancet puncture and is gone into amniotic cavity, and left hand is puncture needle fixedly, and the right hand extracts amniotic fluid with syringe then.Because puncture needle is very thin, being very easy to up and down, transposition causes the damage in fetus or uterus.In addition, with the fixing puncture needle of hands, inconvenient operation, effect is not good enough.Therefore, the present technique field demands inventing a kind of amniocentesis pin fixation clamp urgently, to reach fixedly puncture needle, is convenient to operation, atraumatic purpose.
Summary of the invention
This utility model provides a kind of amniocentesis pin fixation clamp for solving the problem that prior art exists, and fixedly puncture needle is convenient to operation, prevents damage.
The purpose of this utility model is achieved through the following technical solutions:
A kind of amniocentesis pin fixation clamp, comprise hinged lower clamping piece and upper clip, elastic clamping pieces, the clamping part that it is characterized in that described lower clamping piece and upper clip front end is laminar, is symmetrical arranged breach on the relative inner edge of lower clamping piece and upper clip clamping part.
To improvement of the technical scheme: the breach on described lower clamping piece and the upper clip clamping part inner edge is a zigzag.
Another kind to technique scheme improves: the gap portions on described lower clamping piece and the upper clip clamping part inner edge is provided with the software pad.
To further improvement in the technical proposal: described lower clamping piece and upper clip are the integrative-structure of injection mo(u)lding.
To further improvement in the technical proposal: described lower clamping piece and upper clip clamping part shape are the first quarter moon shape, lower clamping piece and the relative inner edge of upper clip clamping part are straight flange, and the breach of described lower clamping piece and upper clip clamping part all is arranged on its straight flange middle part.
To further improvement in the technical proposal: described elastic clamping pieces is " Ω " shape elastic ring, and " Ω " shape elastic ring passes lower clamping piece and upper clip rear end, and " Ω " shape elastic ring two ends withstand on the clamping part outside of lower clamping piece and upper clip respectively.
To further improvement in the technical proposal: non-woven fabrics or soft fabric are set on the clamping part of described lower clamping piece and upper clip and the human body skin contact surface.
This utility model compared with prior art has following advantage and good effect:
1. the lower clamping piece of this utility model amniocentesis pin fixation clamp and upper clip are laminar, the laminar clamping part and the contact skin that meet stomach wall physiology shape, the trocar sheath that the gap portions of lower clamping piece and upper clip clamping part is clamped puncture needle fixedly puncture needle in the position of needs, easy to operate, good fixing effect, limit moving up and down of puncture needle, avoided the damage in fetus and uterus;
2, this utility model is designed to zigzag with the breach on lower clamping piece and the upper clip clamping part inner edge or the gap portions on lower clamping piece and upper clip clamping part inner edge is provided with the software pad, makes the effect that grips puncture needle more reliable;
3, simple and reasonable for structure, be convenient to clinical use.
Description of drawings
Fig. 1 is the front view of this utility model amniocentesis pin fixation clamp embodiment 1;
Fig. 2 is the front view of this utility model amniocentesis pin fixation clamp embodiment 2.
The specific embodiment
Referring to Fig. 1, the embodiment 1 of a kind of amniocentesis pin of this utility model machine fixation clamp comprises lower clamping piece 1 and upper clip 2, elastic clamping pieces 4, and lower clamping piece 1 is hinged by hinge axis 3 with upper clip 2 middle parts.
The clamping part of described lower clamping piece 1 and upper clip 2 front ends is laminar, be symmetrical arranged breach 1-1,2-1 on the relative inner edge of lower clamping piece 1 and upper clip 2 clamping parts, breach 1-1,2-1 on described lower clamping piece 1 and the upper clip 2 clamping part inner edges are zigzag (as shown in Figure 1).Above-mentioned lower clamping piece 1 and upper clip 2 clamping part shapes are the first quarter moon shape, and lower clamping piece 1 and the relative inner edge of upper clip 2 clamping parts are straight flange, and breach 1-1, the 2-1 of described lower clamping piece 1 and upper clip 2 clamping parts all are arranged on its straight flange middle part.
Above-mentioned elastic clamping pieces 4 is " Ω " shape elastic metallic ring, and " Ω " shape elastic ring passes lower clamping piece and upper clip rear end, and " Ω " shape elastic metallic ring 4 two ends withstand on the clamping part outside of lower clamping piece 1 and upper clip 2 respectively.
Described lower clamping piece 1 and upper clip 2 are the integrative-structure of injection mo(u)lding, on the clamping part of lower clamping piece 1 and upper clip 2 and human body skin contact surface non-woven fabrics or soft fabric are set.Can alleviate anemia of pregnant woman's sense of discomfort.
The basic structure with embodiment 1 of this utility model amniocentesis pin fixation clamp embodiment 2 is identical, and difference is: the gap portions of embodiment 2 on lower clamping piece 1 and upper clip 2 clamping part inner edges is provided with software pad 1-2,2-2(as shown in Figure 2).
When amniocentesis is put sheep out to pasture water or extraction amniotic fluid, puncture needle is aimed at the abdominal part puncture position, clamp the trocar sheath of puncture needle with the puncture needle fixed-site with this utility model amniocentesis pin fixation clamp gap portions.The operative doctor right hand is held lancet puncture and is gone into amniotic cavity, and the right hand extracts amniotic fluid with syringe then.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and this utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of having done, remodeling, interpolation or replacement also should belong to protection domain of the present utility model.
