Description

Single use cytology brush

Technical field

This utility model relates to clinical supporting endoscopic biopsy sampling equipment, especially single use cytology brush.

Background technology

At present, splanchnoscopy has been widely used for clinic as a kind of aided diagnosis method, and cytology brush is by swipe diseased region tissue mucus in endoscope channel entrance patient body, then the tissue mucus taken out is carried out pathological analysis to make a definite diagnosis disease.Endoscope's cell tissue sampling, because of its hurtless measure, checks the convenient splanchnoscopy means having become routine.Cytology brush manufacturing process the most on the market is complicated, and cost is high and quality stability is poor, malfunction, increases sampling difficulty.

Utility model content

Based on background above, and when the design of device in view of the motility of device and the feasibility of manufacture, the utility model discloses a kind of with low cost, structure reliable, stable operation, easy to connect, be simple to manufacture, sample conveniently single use cytology brush.

This utility model solves its technical problem the technical scheme is that single use cytology brush, including brush, hands ring, slip ring, bristle, outer sheath, steel wire rope and hands handle, described handle has inwardly dug groove, handle front end is provided with the through hole that can lead to steel wire rope, handle afterbody integral type is provided with hands ring, bracelet is provided with manhole, slip ring movable type is connected on the groove of handle, steel wire rope by the through hole of handle and is fixed with slip ring, the steel wire rope that spiral twists into, steel wire rope is fixedly arranged at the front end with brush, and outside steel wire rope, it is cased with outer sheath, it is fixing that bristle on brush is that wirerope-winding bristle is formed, brush front end is smooth circular arc body.

As preferably, described outer sheath is that polytetrafluoroethylmaterial material is made.

As preferably, described bristle is that polycaprolactam material is made.

As preferably, described steel wire rope is that rustless steel is made, and rustless steel is 1Cr18ni9 material.

The beneficial effects of the utility model: with low cost, structure is reliable, stable operation, easy to connect, be simple to manufacture, sample convenient and swift, Quality of Steel Wire Rope is reliable, the most flexible.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

As shown in Figure 1, single use cytology brush, including brush 1, bracelet 2, slip ring 3, bristle 4, outer sheath 5, steel wire rope 6 and handle 7, described handle 7 has inwardly dug groove, handle 7 front end is provided with the through hole that can lead to steel wire rope 6, handle 7 afterbody integral type is provided with bracelet 2, bracelet 2 is provided with manhole, slip ring 3 movable type is connected on the groove of handle 7, steel wire rope 6 passes through the through hole of handle 7 and is fixed with slip ring 3, the steel wire rope 6 that spiral twists into, steel wire rope 6 is fixedly arranged at the front end with brush 1, and outside steel wire rope 6, it is cased with outer sheath 5, bristle 4 on brush 1 is wound around bristle 4 for steel wire rope 6 and is formed fixing, brush 1 front end is smooth circular arc body.Described outer sheath 5 is made for polytetrafluoroethylmaterial material.Described bristle 4 is made for polycaprolactam material.Described steel wire rope 6 is made for rustless steel, and rustless steel is 1Cr18ni9 material, reliable in quality.Bristle 4 and outer sheath 5 answer no cytotoxicity, should be without delayed hypersensitivity, should be without oral mucosa irritant reaction, and the bristle 4 on brush 1 is wound around bristle 4 for steel wire rope 6 and is formed fixing, and bristle 4 stable connection does not comes off.Brush 1 front end is smooth circular arc body, is easily accessible.The beneficial effects of the utility model: with low cost, structure is reliable, stable operation, easy to connect, be simple to manufacture, sample convenient and swift, Quality of Steel Wire Rope is reliable, the most flexible.
