This obstetrical midwifery forceps is through two toper chambeies that set up the opposition in the air duct to and the echelonment biconial negative pressure cavity of inner chamber and exocoel constitution, can make negative pressure maintain constant.
Description
Technical field
This utility model belongs to field of medical equipment technology, is specifically related to a kind of obstetric forceps for obstetrical department.
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 obstetric forceps for obstetrical department that can keep constant captivation.
The purpose of this utility model is achieved through the following technical solutions.
A kind of obstetric forceps for obstetrical department, comprise inlay and airway, 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 and back-end of described airway are connected to suction nozzle and negative pressure bottle, 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 further technical scheme of this utility model is: the front end of described inlay is connected with the embedding palm.
This utility model further technical scheme is: described negative pressure bottle is provided with control valve.
The beneficial effect that this utility model produces owing to taking above-mentioned technological means is: obstetric forceps for obstetrical department of the present utility model, 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.
Accompanying drawing explanation
Fig. 1 is the structural representation of obstetric forceps for obstetrical department of the present utility model.
In figure, 1-inlay, the embedding palm of 2-, 3-airway, 4-regulating sleeve, 5-hollow 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-negative pressure bottle, 18-control valve.
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.
Obstetric forceps for obstetrical department of the present utility model as shown in Figure 1, comprise a pair inlay 1, airway 3, the front end of inlay 1 is connected with the embedding palm 2, airway 3 has hollow 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 and back-end of airway 3 are connected to suction nozzle 8 and negative pressure bottle 17, negative pressure bottle 17 is provided with control valve 18, 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 hollow tube chamber 5.
Obstetric forceps for obstetrical department of the present utility model, by arranging two opposed conical cavities in airway, negative pressure is made to form jump, increase once resistance of giving birth to and be convenient to the distribution of hollow pipe intracavity, the firm absorption fetal head of suction nozzle can be made, by the stepped biconial negative pressure cavity that inner chamber and exocoel form, when can ensure to block one of them, attraction channel is unimpeded, and negative pressure can be made to maintain.
The above embodiment only have expressed embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be as the criterion with claims.
