Elastic drainage pipeline punching die

Abstract

The invention discloses an elastic drainage pipeline punching die. The elastic drainage pipeline punching die comprises an upper die body and a lower die body. The upper die body comprises an ejector block, a base and a plurality of tools. The ejector block and the base are connected through a plurality of bolts. One end of each tool is fixed to the ejector block, and the other end of each tool penetrates the base. The base is provided with pressing protrusions, and the pressing protrusions are arranged on the lower surface of the base. The lower die body comprises a base and a gasket, the gasket is arranged on the base, and the upper die body is arranged over the lower die body. The punching die is provided with the pressing protrusions, and therefore an elastic drainage pipeline can be flattened, and punching is facilitated; the silica gel or rubber gasket is arranged, tenacity is good, and meanwhile the drainage pipeline is prevented from being damaged; the tools are arranged and can rapidly cut off the drainage pipeline, and punching is achieved; the die is simple in structure, convenient to operate and exquisite in detail design; and the punching precision is high.

Description

technical field [0001] The invention relates to a mold, which is mainly used for punching holes for elastic drainage pipelines. Background technique [0002] Drainage tubes are generally used after surgical operations, and are mainly used to guide pus, blood, liquid, etc. accumulated in human tissues or body cavities to the outside of the body to prevent postoperative infection and promote wound healing. There are many kinds of drainage tubes used in clinical surgery at present. Most of the holes on the existing drainage tubes are symmetrically punched. When this kind of drainage tube is in use, granulation is easy to grow in the holes, and it is easy to damage the human body organs when the patient is extubated; It is impossible to punch holes on both sides of the pipe body even if the holes are punched on the road. There are many burrs on the wall of the drainage tube formed by some equipment, which cannot be used in the medical device industry. Contents of the inventi...

AI Technical Summary

Problems solved by technology

Most of the holes on the existing drainage tubes are symmetrically punched. When this kind of drainage tube is used, granulation is easy to grow in the holes, and the patient's organs are easy to be damaged when the patient is extubated; Holes are drilled on the road, and holes cannot be distributed staggeredly on both sides of the pipe body

There are many burrs on the wall of the drainage tube formed by some equipment, which cannot be used in the medical device industry.
