a cutter

Abstract

The invention provides a cutter, which comprises a shell, a cutting knife element and an elastic element. A cutting area is arranged on the bottom part of the shell; one or more cutting holes penetrating through the shell are formed in the cutting area; the cutting knife element is arranged in the shell; a blade of the cutting knife element faces the cutting area, and intersects with extension directions of the cutting holes; the elastic element is arranged in the shell, is connected with the cutting knife element, and is used for keeping the cutting knife element to stay in a position far away from the cutting area in the shell; an opening part is arranged on the top part of the shell; and the cutting knife element is pressed through the opening part so as to cut catheters in the cutting holes. During work, the cutting knife element is pressed so as to cut the catheters in the cutting holes, and can be recovered to the position far away from the cutting area under the action of the elastic element after the cutting is completed, so that the cutting efficiency of the cutter is improved. Meanwhile, the cutting knife element keeps pressing on the top part position, and can be used for cutting at any position state.

Description

technical field [0001] The invention relates to the technical field of medical catheter cutting, in particular to a medical catheter cutter. Background technique [0002] Catheters are used frequently in a variety of medical care practices and vary in length depending on the type of care and patient. Therefore, prior to performing medical care work, it is often necessary to cut the catheter to obtain a suitable length of catheter. [0003] Currently, healthcare professionals typically cut catheters with manual scissors or a scalpel. For example, Chinese patent CN203650582U discloses a medical pipe cutting blade, which includes a main cutting part, a secondary cutting part and a knife back part, wherein the angle between the cutting surfaces of the main cutting part can be 20-25 degrees, and the cutting of the secondary cutting part The included angle between the surfaces may be 3-8 degrees. However, since the above-mentioned blade needs to be manually controlled to cut th...

Problems solved by technology

However, this cutter requires a specific direction when used, that is, the blade cannot move from top to bottom to cut. Staying at the bottom of the card slot, when using the cutter again, it is necessary to manually move the blade to the top of the card slot before performing the cutting operation, resulting in low cutting efficiency

In addition, the blade is easily stuck in the card slot, making the movement of the blade more time-consuming and laborious
