Technical Field

The invention belongs to the technical field of medical surgical instruments, and particularly relates to an umbilical cord shearing device.

Background

When a mother gives a birth, the umbilical cord of the baby is usually cut off by a traditional surgical scissors, then the umbilical cord is tied off, and the umbilical cord naturally falls off after the umbilical cord is dried, so that the method is troublesome and increases the infection probability of the umbilical cord of the baby. At present, an umbilical cord scissors clamp appears on the market, two integral umbilical cord clamps with connecting strips are arranged on a fixing frame with blades in a side-by-side mode, the umbilical cord clamps clamp infant umbilical cords through two arms of a pressing fixing frame and simultaneously cut off the umbilical cords and the connecting strips between the umbilical cord clamps, and the arms of the fixing frame are pressed by one hand after being opened, so that large force is needed, and the operation is inconvenient.

In order to improve the operating performance of the umbilical cord scissors clamp, Chinese patent application No. 201010519307.4, the application publication date is 2011, 2, 9, the name of the invention is: the umbilical cord scissors comprise a first scissors element and a second scissors element which are connected through a pin shaft, the head of the first scissors element is provided with a blade, the head of the second scissors element is provided with a blade groove corresponding to the blade, two sides of the blade at the head of the scissors element are provided with installation parts of a toothed umbilical cord clamp, two clamp springs extend from a connecting part of the pin shaft between the scissors elements, a handle of the scissors element is pressed, the head of the scissors element is closed, because the height of the blade edge is lower than that of the upper edge of the toothed umbilical cord clamp, a clamping connecting structure of the upper edge clamp and the lower edge clamp port of the umbilical cord clamp is clamped and fixed firstly, the umbilical cord between the two umbilical cord clamps is positioned at the moment, the handle of the scissors element is pressed forcefully again, the elastic force of the clamp springs supported on the handle is overcome, the blade cuts the umbilical cord in the middle part, and the umbilical cord clamps, the operation is completed.

However, the above umbilical cord scissors have the following drawbacks:

1) adopt rectangular shape umbilical cord clamp to ligate the umbilical cord, vertical V-arrangement groove not only drops easily, causes new surface of a wound easily at the in-process of extrusion umbilical cord moreover, has increaseed the risk of infection, and the umbilical cord slides in pressing from both sides not well fixedly when using long shape form moreover, is easily bumped in the ligature later stage, also hinders medical personnel's operation simultaneously.

2) Because the umbilical cord clamps are generally made of PP materials with higher hardness, in the using process of the umbilical cord clamps, the isolating cloth needs to be arranged at the bottom of the umbilical cord clamps, so that a new wound surface is avoided being easily caused in the process of extruding the umbilical cord, the risk of infection is increased, and the operation is complicated.

In view of the above technical problems, it is desirable to improve the same.
