Embodiment 1

[0023] During specific implementation, a kind of high-performance gynecological forceps, such as figure 1 As shown, it includes a clamping part 1 and a tightening part 2 whose centers of gravity are on the same axis. The top edge of the tightening part 2 fits against the bottom outer wall of the clamping part 1. Three clamping rods 3 are distributed, and the clamping rods 3 are arc-shaped supports 4 bent upwards from the bottom, so that the three clamping rods 3 form a funnel shape, and the bottoms of the arc-shaped supports 4 are gathered and fixed at the joint 5 , the connection 5 is located on the central axis of the tightening part 2, the other end of the connecting part 5 is fixed with a pole 10, the other end of the pole 10 is fixed with a handle 11, the tightening part 2 The outer wall is provided with a handle 12, and a limit stop is provided between the joint 5 and the pole 10 to ensure that the joint 5 is always located on the central axis of the tightening part 2 wh...

Embodiment 2

[0028] In another embodiment, a high-performance gynecological forceps, such as image 3 As shown, the difference from Example 1 is that the tightening part 2 is provided with two symmetrical clamping rods 3, the tightening part 2 is an inverted triangular pyramid, and the top of the tightening part 2 The edge fits against the outer wall of the bottom of the clamping part 1. The lower end of the tightening part 2 is connected with a handle part 16, and its bottom cone is embedded in the inside of the handle part 16. The clamping part 1, the tightening part 2, the handle The position of the center of gravity axis of the part 16 is provided with a shrink tube 13. The shrink tube 13 is made of hard material, the inside is hollow, and has a certain tensile strength. The bottom end of the clamping part 1 passes through the shrink tube 13. It is clamped with the tightening part 2, and the connection 5 between the shrink tube 13 and the clamping part 1 is provided with a correspondin...

Abstract

The invention belongs to the field of medical apparatuses and instruments and particularly relates to high-performance obstetric forceps for the gynecology department. The high-performance obstetric forceps comprise a clamping part, a tightening part and a handheld part with the gravity centers on the same axis, the edge of the top of the tightening part fits and abuts against the outer wall of the bottom of the clamping part, and the handheld part is connected to the lower end of the tightening part; the clamping part comprises multiple clamping rods distributed at equal intervals, the clamping rods are arc supporting parts with bottoms bent upwards, the bottoms of the arc supporting parts are gathered and fixed to the junction, the tops of the arc supporting parts are divergent, and rolling boxes are radically and fixedly embedded in the arc supporting parts; two rolling shafts are arranged in each rolling box, the upper and lower ends of each rolling shaft are fixedly connected withthe rolling boxes through springs, convolutional clamping sleeves are fixedly arranged on the rolling shafts, and electromagnetic induction parts are arranged at the tail ends of the clamping sleeves. According to the high-performance obstetric forceps, the arranged clamping part is retractable and can be contracted into a columnar shape before the high-performance obstetric forceps enter the birth canal, the high-performance obstetric forceps conveniently enter the birth canal, after the high-performance obstetric forceps are in contact with a fetus, the clamping part is manually spread, theintensity is conveniently controlled, and the fetus and a mother body cannot be injured.

Description

technical field [0001] The invention belongs to the field of medical instruments, in particular to a high-performance gynecological forceps. Background technique [0002] Forceps are an instrument that can be used to assist a mother in delivering her baby. Forceps midwifery is one of the important means to solve cephalic dystocia, shorten the second stage of labor, and terminate pregnancy as soon as possible. In the prior art, the forceps consisted of two branches (blades) positioned around the fetal head. These branches are defined as left and right lobes depending on which side of the mother's pelvis they are applied to. Branches usually (but not always) cross at the midpoint of the joint. Most forceps have locking features at the joint, but a few have sliding features that allow the two branches to slide along each other. Forceps with a fixed locking structure are used for deliveries that require little or no rotation, such as when the fetal head is aligned with the m...
