Abstract

The invention discloses a gastrointestinal endoscopy pathological sampling filter paper cutting device, and relates to a sampling filter paper cutting device. In a gastrointestinal endoscopy sampling process, filter paper for samples need to be selected according to the types and attributes of the samples, and because the number, size and clean demands of the filter paper sheets are strict, the cutting working of the filter paper is complex and cost lots of time and effort. In the invention, a paper feeding wheel rolls on a lower paper guide plate; a force application opening is formed in a housing; the force application opening faces the paper feeding wheel; a gap is formed between an upper paper guide plate and the lower paper guide plate; the gap between the upper paper guide plate and the lower paper guide plate is a filter paper sending-out channel; a cutter assembly is arranged on an outlet end of the filter paper sending-out channel; the cutter assembly is near a filter paper outlet; a filter paper winding wheel is arranged on one end away from the cutter assembly, of the lower paper guide plate; a cutting switch is arranged on the housing; a part positioned in the housing, of the cutting switch is tightly attached to the cutter assembly through a cutter pushing mechanism; a part positioned outside the housing, of the cutting switch is a hand pull portion. The gastrointestinal endoscopy pathological sampling filter paper cutting device is used for cutting sampling filter paper.

Description

technical field [0001] The invention relates to a sampling filter paper cutter, which belongs to the technical field of medical instruments. Background technique [0002] Gastroenteroscopy is often used for pathological sampling. Pathological sampling is to use special equipment to take a small amount of tissue from the patient's gastrointestinal tract, put it on a small piece of special filter paper, put it into a sample bottle, and send it to the pathologist. The laboratory conducts pathological laboratory analysis. Many patients undergo gastrointestinal endoscopy in large hospitals. Different pathological conditions require different samples, and the size and quantity of filter paper required are also different. Some patients are prone to confusion of different parts when the sample volume is large. It is time-consuming to cut filter paper at any time. At present, filter paper of different sizes is cut for backup. It is inconvenient to find out the filter paper you need ...
