Abstract
The utility model discloses a double-sheath bushing pathology biopsy puncture needle which comprises a puncture needle and an outer sheath bushing; the left end of the puncture needle is a puncture needle handle; the right side of the puncture needle handle is a strip-shaped needle head; the left end of the outer sheath bushing is an outer sheath bushing handle; and the right side of the outer sheath bushing handle is a strip-shaped outer thin-wall cylinder. The double-sheath bushing pathology biopsy puncture needle is characterized by also comprising an inner sheath bushing; the left end of the inner sheath bushing is an inner sheath bushing handle; the right side of the inner sheath bushing handle is a strip-shape inner thin-wall cylinder; the length of the inner thin-wall cylinder is slightly smaller than the length of the needle head so that a needle tip can be exposed; a side hole with a blade is arranged in the circumference of the right end of the inner thin-wall cylinder; and the length of the outer thin-wall cylinder is slightly smaller than the length of the inner thin-wall cylinder so that the side hole with the blade can be exposed. The problem of inconvenience in use of the current puncture needle which intensifies the pain of patients is solved. The double-sheath bushing pathology biopsy puncture needle is suitable for pathology biopsy sampling.
Description
Technical field
This utility model relates to field of medical appliances, a kind of specifically pathological biopsy puncture needle device.
Background technology
At present, traditional biopsy needle has only puncture needle and interior sheath sleeve pipe, and interior sheath sleeve pipe front end has the arc knife edge, and the pathological tissue of being got falls easily, and each puncture finishes to be needed puncture needle is withdrawed from, and wants repeated puncture when needing, and causes suffering to the patient.
Summary of the invention
This utility model provides a kind of split type puncture needle that has bilayer sleeve for solving the problem that present puncture needle uses inconvenience, increases patient's misery.
The technical solution of the utility model is, a kind of pair of sheath sleeve pipe pathological biopsy puncture needle, comprise puncture needle, the epitheca sleeve pipe, the puncture needle left end is the puncture needle handle, puncture needle handle right side is the long strip type syringe needle, epitheca sleeve pipe left end is an epitheca sleeve pipe handle, epitheca sleeve pipe handle right side is the outer thin cylinder of long strip type, its special character is, sheath sleeve pipe in also comprising, interior sheath sleeve pipe left end is interior sheath sleeve pipe handle, interior sheath sleeve pipe handle right side is a thin cylinder in the long strip type, and interior thin cylinder length slightly is shorter than needle length can make needle point exposed, has the side opening of the band knife edge on the interior thin cylinder right-hand member circumference, the knife edge can adopt triangle, arcs etc. are convenient to extract the shape of pathological tissue, and thin cylinder length can make the side opening of the band knife edge exposed in outer thin cylinder length slightly was shorter than.The edge of puncture needle handle right side can be processed with positioning convex, and corresponding positioning convex is processed with locating slot in the interior sheath sleeve pipe handle left side.Outer thin cylinder can be provided with graduation mark on the surface.
During use, puncture needle is inserted interior sheath sleeve pipe, again both are inserted the epitheca sleeve pipe.Two sheath sleeve pipe puncture needles are thrust focus, the graduation mark that can observe on the outer sheath pipe confirms whether the position is suitable, extract puncture needle, try to have or not abnormal conditions such as hemorrhage, after slightly the sheath sleeve pipe is taken a sample in the rotary pulling, sheath sleeve pipe in extracting, the effective hands of outer sheath is fixed on the patient body, and the side opening inner tissue that takes out the band knife edge send pathological biopsy, interior sheath sleeve pipe can be inserted the epitheca sleeve pipe once more when needing, repeat to draw materials 3-5 time, avoided repeated puncture to reduce patient's misery.
Technique effect of the present utility model is to adopt technique scheme can realize a kind of pathological biopsy puncture needle device simple in structure, easy to use.

In the drawings, side opening, 10 epitheca sleeve pipe handles, 11 epitheca sleeve pipes, 12 graduation marks, the 13 outer thin cylinders of sheath sleeve pipe handle, 7 interior sheath sleeve pipes, 8 interior thin cylinders, the 9 band knifes edge in 1 puncture needle handle, 2 puncture needles, 3 positioning convex, 4 syringe needles, 5 locating slots, 6.
The specific embodiment
Embodiment further specifies this utility model below in conjunction with accompanying drawing.
As shown in FIG., puncture needle 2 left ends are puncture needle handle 1, puncture needle handle 1 right side is a long strip type syringe needle 4, epitheca sleeve pipe 11 left ends are epitheca sleeve pipe handle 10, epitheca sleeve pipe handle 10 right sides are the outer thin cylinder 13 of long strip type, interior sheath sleeve pipe 7 left ends are interior sheath sleeve pipe handle 6, interior sheath sleeve pipe handle 6 right sides are thin cylinder 8 in the long strip type, interior thin cylinder 8 length slightly are shorter than syringe needle 4 length can make needle point exposed, have the side opening 9 of the band knife edge on the interior thin cylinder 8 right-hand member circumference, the knife edge can adopt triangle, arcs etc. are convenient to extract the shape of pathological tissue, and thin cylinder 8 length can make the side opening 9 of the band knife edge exposed in outer thin cylinder 13 length slightly were shorter than.The edge of puncture needle handle 1 right side can be processed with positioning convex 3, and protruding 3 of corresponding location is processed with locating slot 5 in interior sheath sleeve pipe handle 6 left sides.Outer thin cylinder can be provided with graduation mark 12 on 13 surfaces.
During use, puncture needle 2 is inserted interior sheath sleeve pipe 7, again both are inserted epitheca sleeve pipe 11.Two sheath sleeve pipe puncture needles are thrust focus, the graduation mark 12 that can observe on the outer sheath pipe 11 confirms whether the position is suitable, extract puncture needle 2, try to have or not abnormal conditions such as hemorrhage, after slightly sheath sleeve pipe 7 is taken a sample in the rotary pulling, sheath sleeve pipe 7 in extracting, epitheca sleeve pipe 11 usefulness handss are fixed on the patient body, and side opening 9 inner tissues that take out the band knife edge send pathological biopsy, interior sheath sleeve pipe 7 can be inserted epitheca sleeve pipe 11 once more when needing, repeat to draw materials 3-5 time, avoided repeated puncture to reduce patient's misery.
