Technical field
The present invention relates to medical catheter cutting technique fields, and in particular to a kind of medical catheter cutter.
Background technique
Conduit is often used in various medical nursing works, and not according to the difference of nursing type and patient
Together, the length of required conduit would also vary from.Therefore, before carrying out medical nursing work, it usually needs carried out to conduit
It cuts to obtain the conduit of appropriate length.
Currently, medical staff usually cuts conduit using manual scissors or scalpel.For example, Chinese patent CN
203650582U discloses a kind of medical tubing cutting blade, including main cutting portion, secondary cutting portion and knife spine part, wherein master cuts
Cutting the angle between the cutting surface in portion can be 20-25 degree, and the angle between the cutting surface of secondary cutting portion can be 3-8 degree.So
And since insert needs to easily cause scuffing to be easy to cause conduit notch uneven using the process of hand-guided cutting
Accident influences medical and nursing quality, and increases medical staff's workload, and reduces medical care efficiency.
For this purpose, Chinese patent CN201863230U provides a kind of direct cutting type medical catheter cutter, including T-type notch,
Insert pocket is set on the inside of notch.When needing cutting catheter, conduit can be put into the bottom of T-type notch, blade card will be placed in
Blade in slot is pressed.However, requiring specific directionality when the cutter use, i.e. blade cannot move from the top down
Cutting, which can fall with self weight blocks duct entry, cannot be inserted into conduit cutting, and executing cutting behaviour
Blade can rest on card slot bottom after work, need that blade is moved at the top of card slot first with craft when reusing cutter,
Cutting operation is executed again, thus causes cutting efficiency lower.In addition, blade is easy to be stuck in card slot, so that the movement of blade is more
Add time-consuming and laborious.
Summary of the invention
