Description
Technical field
The utility model relates to a kind of polypectomy collection devices.
Background technique
Pipe intestinal polyp patient, under gastroscope or colonoscopy high-frequency electrical extract excision polyp after, polyp need to by completely be taken out into
Row pathologic finding, with clear lesion nature and whether there is or not cancerations, this is most important to the selection of successive treatment scheme.In prior art
In, usual scope host is connected with attractor, and when Gastrointestinal Endoscopes operate, intracavitary water and mucus are by attracting duct to enter aspirator.
When extracing polyp, lesser polyp can be sucked out Gastrointestinal Endoscopes by biopsy duct, and biggish polyp need to grab object pincers (such as through dedicated
Snare) it takes out or through vacuum suction in mirror surface, it is exited with Gastrointestinal Endoscopes.But the lesser polyp in part, easily through negative after excision
It holds up and is drawn to negative pressure drainage vessel, inspection can not be separated；The biggish polyp in part can not once take out, and need to often be cut into several pieces, it
It successively takes out afterwards, good inspection again is then spliced according to cut mark, often leads to the disease of incisxal edge because can not accurately splice in splicing
Manage difficult diagnosis.In addition, the polyp of part excision can be because gravity or peristalsis of the digest tract slide into pleat gap, it is difficult to grab or look for
It arrives.Sometimes because looking for difficulty, whether doctor abandons grabbing and requiring patient to notice polyp and excrete with stool, send again after collection
Pathologic finding leads to not row pathological diagnosis if sample is lost.
Summary of the invention
Polyp that is simple the purpose of this utility model is to provide a kind of structure and integrate polypectomy and taking-up is cut
Except collection device.
The purpose of this utility model is achieved through the following technical solutions: a kind of polypectomy collection device, it includes being equipped with
