Clamping and shearing device for newborn umbilical cord

Abstract

The invention belongs to the field of medical instruments, and provides a clamping and shearing device for the newborn umbilical cord. The clamping and shearing device comprises two forceps bodies hinged through a hinging shaft. An umbilical cord clamp, a blade and another umbilical cord clamp are sequentially arranged in a jaw of each forceps body from one side of the jaw to the other side of the jaw. The blades cut the umbilical cord when the umbilical cord clamps clamp the umbilical cord or after the umbilical cord clamps clamp the umbilical cord, the umbilical cord clamps are locked through mutual locking structures, and the two umbilical cord clamps of each forceps body clamp the two ends of the shorn portion of the umbilical cord respectively. The umbilical cord clamps are separated from the jaws through the pushing effect on umbilical cord clamp connecting ribs from the front ends of elastic strips. The connecting ribs are provided with protruding edges, and the protruding edges limit the elastic strips when the elastic strips push the umbilical cord clamps so as to guarantee that the force application position is reliable. Reinforcing ribs are arranged on the outer side surfaces of clamping arms of the umbilical cord clamps, and therefore the strength of the umbilical cord clamps is fully guaranteed, the strength of the clamping movement of the umbilical cord clamps can be effectively guaranteed, and deformation does not occur easily. The clamping and shearing device for the newborn umbilical cord is reasonable in structure and convenient to use and greatly shortens the ligation time of the umbilical cord.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an umbilical cord clipper for newborns. Background technique [0002] In order to realize convenient and fast ligation of the umbilical cord of newborns, Chinese patent application CN1689532A provides a disposable umbilical cord scissors, which are composed of left scissors body and right scissors body hinged to form scissors, the front end of the scissors body is scissors seat 01, The rear end is a handle 02, and a notch holder 03 is fixed on the inner side of the two scissor seats 01, and a protrusion is provided at both ends of the notch holder 03, and the notch on one side passes through the protrusion. The deck 03 is equipped with scissors blade 04 and notch clip bar 05, and the blade is positioned at the notch, and the scissors bar is housed on the notch deck on the other side, and is scissors-like between described scissors blade; Elastic pliers 06 are respectively prov...

AI Technical Summary

Problems solved by technology

However, the umbilical cord scissors with this structure have the following defects: 1. When the arc-shaped elastic strip pushes forward the elastic ring at the end of the elastic clamp, the two are easy to dislocate, and the ejection effect of the arc-shaped elastic strip on the elastic clamp cannot be guaranteed, and arc-shaped elastic strips may appear. The elastic bar fails to bounce the elastic pliers, and the elastic pliers cannot be separated from the scissors base

2. The clamp arm of the elastic pliers is a straight plate structure, which is easy to deform during the clamping action, and its clamping force is not enough to make the clamping effect of the elastic pliers unreliable
