Description
Technical field
This utility model relates to a kind of practise midwifery pincers, belongs to obstetrics' technical field of medical instruments.
Background technology
In natural labor parturient childbirth process, because a variety of causes often need use the practise midwifery pincers to help fetus to give birth to.Use obstetric forceps spoon portion when present domestic most practise midwifery pincers use one clamp-buckle is arranged; Close pincers backs folder and hold fetus head and give certain pulling force and help fetus to give birth to, fetal head is had certain distortion, and be prone to stay the pincers seal in fetus face; Application obstetric forceps spoon portion pushes the vagina soft tissue open when using and the most practise midwiferys of American-European countries clamp; Reduce resistance, group group fetus is given birth to, and both respectively have pluses and minuses.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned deficiency that exists in the prior art; The structural advantages of the two kinds of practise midwifery pincers in China and foreign countries is combined; Provided a kind of both can the folder to hold the fetal head tractive, and can expand birth canal again and reduce resistance, labour-saving easy to use practise midwifery pincers to power.
The technical scheme that provides according to this utility model: a kind of practise midwifery pincers; Comprise that two obstetric forceps jig arm that are symmetrical set and one are used for the support bar assembly that they are coupled together; It is characterized in that: said obstetric forceps jig arm comprises spoonful portion and shank, and said spoon portion inner concave is fitted with the fetal head flexibility mutually, and convex surface is right mutually with the birth canal flexibility outside the spoon portion; Spoon portion rear end and shank forward end form bending, and said shank forward end is provided with the support bar patchhole; Said support bar assembly comprises first support bar and second support bar, and first support bar and second support bar are L shaped, and their galianconism section is used to insert the support bar patchhole of obstetric forceps jig arm shank, and their long-armed section is connected; The galianconism section of said first support bar and second support bar can freely be rotated in the support bar patchhole, first support bar and long-armed section of second support bar be connected the total length scalable.
As the further improvement of this utility model, the bending angle α of said spoon portion rear end and shank forward end is the 30-45 degree.
As the further improvement of this utility model, said support bar assembly comprises first support bar, second support bar and locking bolt; The cross section of said first support bar and the second support bar galianconism section is circular, and said support bar patchhole is a circular hole; The cross section that said first support bar and second support bar are long-armed section is rectangle; End long-armed section of first support bar is provided with cylindrical shell; Insert in the said cylindrical shell end that said second support bar is long-armed section; Long-armed section of first support bar contacts with long-armed section face face of second support bar, and their contacted one sides are provided with the teeth of staggered engagement; Said locking bolt comprises dead bolt portion and handle portion, and said dead bolt portion is used to insert cylindrical shell and compresses second support bar, makes the teeth face engagement locking of the teeth face and first support bar of second support bar, and said handle portion makes things convenient for inserting and extracting of locking bolt.
As the further improvement of this utility model, said obstetric forceps jig arm shank rear end type of being column structure, the shank rear end is provided with several and is convenient to hands and holds the bent recessed of operation.
This utility model compared with prior art has the following advantages:The spoon portion rear end of obstetric forceps jig arm and shank forward end are the bending of 30-45 degree in this utility model, when reality is used, both can press from both sides to hold also expansiblely, have possessed the advantages of the two kinds of practise midwiferys pincers in China and foreign countries; Obstetric forceps spoon portion does not hollow out, and is beneficial to push fetal head surrounding soft tissue open, reduces the resistance of birth canal; Do not conform to pincers during clamping and can reduce distortion, be difficult for staying the pincers seal in fetus face to fetal head.But the total length flexible of said support bar assembly is pressed from both sides and is held or expand all more laborsaving.
