Abstract

This utility model provides a kind of control to the safety obstetric forceps of fetal head oppressive force, comprise the tong arm of two cross-articulation, tong arm upper end has binding clip, the face that tong arm bottom is relative all has the chute extended along tong arm direction, below being positioned at two tong arm articulated position between two tong arms, place has fixing transverse slat, horizontal sliding bar and threaded rod, fixing transverse slat is positioned at above horizontal sliding bar, and the two ends of horizontal sliding bar are limited in chute respectively, and can slide along chute direction; Tong arm has hole, the two ends of fixing transverse slat are each passed through the hole be positioned on tong arm, and the lower surface of the rotating and fixing transverse slat in threaded rod upper end is connected, and has screwed hole in the middle part of horizontal sliding bar, the lower end of threaded rod is stretched out below horizontal sliding bar through screwed hole, and the lower end of threaded rod has turning handle.When the beneficial effects of the utility model avoid post-tensioning fetal head to fetal head apply too much in pressure, fetal head is damaged.

Description

Control the safety obstetric forceps to fetal head oppressive force

Technical field

This utility model relates to the safety obstetric forceps of a kind of control to fetal head oppressive force.

Background technology

A kind of aid of obstetric forceps to be gynecologist be parturient childbirth in existing technology, obstetric forceps is formed by connecting through U-shaped clamp handle by two relative arc shaped pincers leaf rear ends, during use, hand-held clamp handle, baby's fetal head clamps and outwards draws by pincers leaf, and its deficiency is: obstetric forceps is when drawing fetus fetal head, if user is lacked experience, while automaticly drawing outside, both hands inwardly exert a force, make fetal head bear unnecessary pressure, cause the damage of fetus head.

Summary of the invention

Problem to be solved in the utility model is to provide the safety obstetric forceps of a kind of control to fetal head oppressive force, overcomes deficiency of the prior art.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: control the safety obstetric forceps to fetal head oppressive force, comprise the tong arm of two cross-articulation, described tong arm upper end has binding clip, the face that described tong arm bottom is relative all has the chute extended along described tong arm direction, below being positioned at two described tong arm articulated position between two described tong arms, place has fixing transverse slat, horizontal sliding bar and threaded rod, described fixing transverse slat is positioned at above described horizontal sliding bar, the two ends of described horizontal sliding bar are limited in described chute respectively, and can slide along described chute direction,

Described tong arm has hole, the two ends of described fixing transverse slat are each passed through the described hole on described tong arm, described threaded rod upper end lower surface that is rotating and described fixing transverse slat is connected, in the middle part of described horizontal sliding bar, there is screwed hole, the lower end of described threaded rod is stretched out below described horizontal sliding bar through described screwed hole, and the lower end of described threaded rod has turning handle.

Further, the outside of described tong arm bottom has lantern finger ring.

The advantage that this utility model has and good effect are: owing to adopting technique scheme, when avoiding post-tensioning fetal head to fetal head apply too much in pressure, fetal head is damaged.

In figure: 1-binding clip; 2-tong arm; 3-fixes transverse slat; 4-chute; 5-horizontal sliding bar; 6-threaded rod; 7-turning handle.

Detailed description of the invention

As shown in Figure 1, this utility model provides a kind of control to the safety obstetric forceps of fetal head oppressive force, comprise the tong arm 2 of two cross-articulation, tong arm 2 upper end has binding clip 1, the face that tong arm 2 bottom is relative all has the chute 4 extended along tong arm 2 direction, below being positioned at two tong arm 2 articulated position between two tong arms 2, place has fixing transverse slat 3, horizontal sliding bar 5 and threaded rod 6, fixing transverse slat 3 is positioned at above horizontal sliding bar 5, the two ends of horizontal sliding bar 5 are limited in chute 4 respectively, and can slide along chute 4 direction;

Tong arm 2 has hole, the two ends of fixing transverse slat 3 are each passed through the hole on tong arm 2, the lower surface of the rotating and fixing transverse slat 3 in threaded rod 6 upper end is connected, in the middle part of horizontal sliding bar 5, there is screwed hole, the lower end of threaded rod 6 is stretched out below horizontal sliding bar 5 through screwed hole, and the lower end of threaded rod 6 has turning handle 7.

Rotate the threaded rod 6 i.e. upper-lower position of scalable horizontal sliding bar 5, and then the chucking power of adjustment binding clip 1, do not rotate due to threaded rod 6 when pulling fetal head backward, it is hereby ensured that the chucking power of binding clip 1 is constant, avoid artificially firmly time increase to fetal head pressure.

The outside of tong arm 2 bottom has lantern finger ring (not shown), and lantern finger ring has the effect preventing hand slippage.

Above embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to this utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.

Claims (2)

1. control the safety obstetric forceps to fetal head oppressive force, it is characterized in that: the tong arm comprising two cross-articulation, described tong arm upper end has binding clip, the face that described tong arm bottom is relative all has the chute extended along described tong arm direction, below being positioned at two described tong arm articulated position between two described tong arms, place has fixing transverse slat, horizontal sliding bar and threaded rod, described fixing transverse slat is positioned at above described horizontal sliding bar, the two ends of described horizontal sliding bar are limited in described chute respectively, and can slide along described chute direction;

Described tong arm has hole, the two ends of described fixing transverse slat are each passed through the described hole on described tong arm, described threaded rod upper end lower surface that is rotating and described fixing transverse slat is connected, in the middle part of described horizontal sliding bar, there is screwed hole, the lower end of described threaded rod is stretched out below described horizontal sliding bar through described screwed hole, and the lower end of described threaded rod has turning handle.
