Abstract
The utility model relates to a fine hair taking device which can vice and take fine hair tissue in a uterine cavity. The utility model is composed of a stainless steel outer sleeve pipe, a vice jaw, an inner guide rod, a positioning nut, etc. The utility model adopts the elastic vice jaw to sufficiently vice and take the fine hair tissue, the wound is small, and bleeding and abortion can not happen easily.
Description
This utility model relates to a kind of chorionic villi sampling device, especially can to the early pregnancy chorionic villi from the uterus apace pincers get, and wound is little, is difficult for hemorrhagely, does not damage gestation sac.
At present, drawing materials of known early pregnancy chorionic villi is to adopt blind suction method, promptly inserts the pregnant woman uterus chamber with a diameter 2.5mm plastic tube and reaches fine hair capsule position, draws with the 10ml syringe.By detection, can diagnose embryo's quality early exactly, decision embryo's choice to cell, biochemistry and the molecular genetics of early pregnancy chorionic villi.This method of drawing material tends to occur fine hair intake deficiency, suction or hemorrhage, even gestation is restrainted the adverse consequencess such as causing miscarriage of breaking.
The purpose of this utility model is: a kind of early pregnancy chorionic villi sampler is provided, it can be accurately, fast, capacity ground pincers get chorionic villi, wound is little, is difficult for hemorrhagely, does not damage gestation sac, also is applicable to cervix uteri simultaneously, the drawing materials and treating of tissues such as oral cavity, throat.
The purpose of this utility model is achieved in that and adopts bent type stainless steel outer sleeve pipe, one elasticity chela is installed in trocar sheath, and chela is connected with inner guide, and inner guide adopts elasticity material manufacture preferably, move to adapt in bent type trocar sheath, the pull bar end is provided with stop nut and handgrip.Chela is packed in the trocar sheath, under the telescopic outside constraint, locates merging phase, makes chela lean out trocar sheath when promoting inner guide, removes the constraint of trocar sheath, and chela opens under the effect of self elastic force.Inverse process can make chela merge, to reach the purpose that uterine cavity is drawn materials.
Below in conjunction with drawings and Examples this utility model is further specified:
Fig. 1 is a scheme of erection.
Fig. 2 is the inner guide that has chela.
Among the figure: 1, trocar sheath; 2, chela; 3, inner guide; 4, stop nut; 5, handgrip.
In Fig. 1 embodiment, trocar sheath (1) is made the round cylinder structure that has curvature, chela (2) is packed in the trocar sheath (1), adopt routine disinfection in the use, the sterile working, pulling inner guide (3) makes in the chela retraction trocar sheath (1) and does not expose, under the guiding of B ultrasonic, enter cervical canal, gently paste the palace wall along the uterine cavity direction and reach 3 millimeters to 5 millimeters places of fine hair capsule lower edge, slowly promoting inner guide (3) makes chela (2) lean out outer catheter (1), chela (2) opens, the chorionic villi on fine hair capsule surface is crowded in the open chela (2), promote outer catheter (1) pulling inner guide (3) chela and merge in the withdrawal trocar sheath (1), at last sampler is extracted out, finish the process of drawing materials.
Claims (4)
1, a kind of chorionic villi sampler, in trocar sheath, installation elasticity chela, chela are connected with inner guide, and setscrew nut, handgrip combination are installed, and it is characterized in that: the elasticity chela is connected with the elasticity guide rod.
2, chorionic villi sampler according to claim 1 is characterized in that: stainless steel outer sleeve pipe guiding location, the elasticity chela is packed in the trocar sheath.
3, chorionic villi sampler according to claim 1 is characterized in that: connect an inner guide behind the chela, the chela effect of cannula cavity is outside realized folding down, finishes extracting.
4, chorionic villi sampler according to claim 1 is characterized in that: the chela number of elasticity chela is three-jaw, four paws, five pawls, six pawls, totally four kinds.
