Description
Technical field
This utility model belongs to field of medical equipment technology, is specifically related to a kind of obstetrics Obstetric forceps.
Background technology
Used Obstetric Forceps Delivery is the operation of the solution difficult labour that obstetrics commonly use, and is the practise midwifery method for second stage of labor.Concrete operation method is that obstetric forceps is placed on fetal head both sides, and two leaves of obstetric forceps fasten, and coordinates uterine contraction traction obstetric forceps, a kind of practise midwifery method of fetal head thus assistance is given birth to.Use Used Obstetric Forceps Delivery to there are some risks, such as may cause cervix uteri and the vaginal wall damage of mother, neonate scalp injury, edema or hematoma etc. may be caused.
For avoiding above-mentioned risk, vacuum extractor is combined use by some Obstetric forceps, operation to assist delivery can be made to operate more stable.But its suction of vacuum extractor of the prior art can not remain constant in operative process, once suction nozzle and fetal head depart from, the inlay of Obstetric forceps is easier causes damage to neonatal scalp.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provides a kind of obstetrics' Obstetric forceps that can keep constant captivation.
The purpose of this utility model is achieved through the following technical solutions.
A kind of obstetrics Obstetric forceps, comprise inlay and airway, described airway has the attraction tube chamber of hollow, described airway slides and is provided with regulating sleeve, described regulating sleeve is provided with hold-down nut, described hold-down nut is for being fixed on airway by regulating sleeve, the both sides of described regulating sleeve are respectively hinged with an inlay, described inlay is fixed on regulating sleeve by adjusting nut, the front end of described airway is connected with suction nozzle, the inwall of described airway is provided with wedge shape projection, described wedge shape projection surrounds the first conical cavity, the rear end of described wedge shape projection is connected with trapezoidal projection, described trapezoidal projection surrounds second conical cavity opposed with the first conical cavity, described first conical cavity is communicated with by through hole with the second conical cavity, the guide plate stretching to airway inwall for a pair is provided with in described second conical cavity, the cavity of airway is divided into inner chamber and exocoel by described guide plate, the rear end of described airway is connected with a negative pressure adjustment structure, this negative pressure adjustment structure has elliptical tube, ellipsoid core is provided with in the tube chamber of described elliptical tube, described ellipsoid in-core is provided with connected chamber, described elliptical tube is provided with the knob for driving ellipsoid core.
The further technical scheme of this utility model is: the internal diameter of described connected chamber is identical with attracting the internal diameter of tube chamber.
This utility model further technical scheme is: the front end of described inlay is connected with the embedding palm.
The beneficial effect that this utility model produces owing to taking above-mentioned technological means is: obstetrics of the present utility model Obstetric forceps, by arranging two opposed conical cavities in airway, and the stepped biconial negative pressure cavity of inner chamber and exocoel composition, negative pressure can be made to remain constant.Meanwhile, by arranging negative pressure adjustment structure, can manual adjustments attract time vacuum magnitude.
Accompanying drawing explanation
Fig. 1 is the connected chamber of obstetrics of the present utility model Obstetric forceps and the structural representation attracting tube chamber to be in complete connected state.
Fig. 2 is the connected chamber of obstetrics of the present utility model Obstetric forceps and the structural representation attracting tube chamber to be in semi-connected state.
In figure, 1-inlay, the embedding palm of 2-, 3-airway, 4-regulating sleeve, 5-attracts tube chamber, 6-hold-down nut, 7-adjusting nut, 8-suction nozzle, 9-wedge shape is protruding, 10-first conical cavity, the trapezoidal projection of 11-, 12-second conical cavity, 13-through hole, 14-guide plate, 15-inner chamber, 16-exocoel, 17-elliptical tube, 18-ellipsoid core, 19-connected chamber, 20-knob.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain this utility model, and be not used in restriction this utility model.
Obstetrics of the present utility model Obstetric forceps as depicted in figs. 1 and 2, comprise a pair inlay 1, airway 3, the front end of inlay 1 is connected with the embedding palm 2, airway 3 has attraction tube chamber 5, airway 3 slides and is provided with regulating sleeve 4, regulating sleeve 4 is provided with hold-down nut 6, hold-down nut 6 is for being fixed on airway 3 by regulating sleeve 4, the both sides of regulating sleeve 4 are respectively hinged with an inlay 1, inlay 1 is fixed on regulating sleeve 4 by adjusting nut 7, fix according to the size adjustment of fetal head good inlay 1 adjusting nut 7 during use, the front end of airway 3 is connected with suction nozzle 8, the inwall of airway 3 is provided with wedge shape projection 9, wedge shape projection 9 surrounds the first conical cavity 10, the rear end of wedge shape projection 9 is connected with trapezoidal protruding 11, trapezoidal protruding 11 surround second conical cavity 12 opposed with the first conical cavity 10, first conical cavity 10 is communicated with by through hole 13 with the second conical cavity 12, the guide plate 14 stretching to airway 3 inwall for a pair is provided with in second conical cavity 12, the cavity of airway 3 is divided into inner chamber 15 and exocoel 16 by guide plate 14, through hole 13 is communicated with exocoel 16 with inner chamber 15 by the second conical cavity 12, inner chamber 15 and exocoel 16 all communicate with attraction tube chamber 5, the rear end of airway 3 is connected with a negative pressure adjustment structure, this negative pressure adjustment structure has elliptical tube 17, ellipsoid core 18 is provided with in the tube chamber of elliptical tube 17, connected chamber 19 is provided with in ellipsoid core 18, elliptical tube 17 is provided with the knob 20 for driving ellipsoid core 18, the end of negative pressure adjustment structure is for connecting negative pressure device, as preferably, the internal diameter of connected chamber 19 is identical with attracting the internal diameter of tube chamber 5.
