Description

Rotary-cutting type pathology soft tissue aspiration biopsy pin
Technical field: this utility model relates to a kind of medical apparatus, and specifically a kind of rotary-cutting type pathology soft tissue aspiration biopsy pin is applicable to human body soft tissue pathological biopsy samplings such as lymph node, thyroid, mastadenoma and other position tumors.
Background technology: all determine that by the section biopsy tumor is optimum or pernicious for all kinds of tumors clinically.Sampling at present cuts with scalpel in operation process mostly, and this shortcoming that cuts method is: surgical technic requires high, and is also more bothersome, big to patient trauma, expense is high, if virulent, also causes the diffusion or the transfer of tumor easily, increases the pathological changes probability; The employing puncture sampling that also has, as the Chinese patent publication number be: the Patent project of CN2449657, name is called pathology soft tissue aspiration biopsy pin, comprise that needle guard, nook closing member constitute, establish barb on nook closing member, the shear force when pulling back by the nook closing member barb cuts tissue, though this biopsy needle has alleviated patient's misery, saved spending, but the tumor tissues that cuts out is poor because of the effect flakiness that is squeezed, influence chemical examination effect.
Summary of the invention: technical problem to be solved in the utility model provides a kind of section that not only need not to perform the operation, alleviates patient's misery, reduces expenses, and the section flakiness is good, can improve the rotary-cutting type pathology soft tissue aspiration biopsy pin of chemical examination effect.
For realizing above purpose, the technical scheme that this utility model adopted is: this rotary-cutting type pathology soft tissue aspiration biopsy pin, constitute by needle guard and nook closing member, the needle tip of needle guard front end is the solid conical head, can be beneficial to the puncture inserting needle, side at the needle tubing of solid conical head and needle tubing junction is established needle guard strip hole, and two vertical edges in needle guard strip hole are blade; Nook closing member is a tubulose, and the top is a disk, is close to the bottom surface of solid conical head in the needle guard, also establishes nook closing member strip hole on the vertical tube wall of nook closing member, and two vertical edges in nook closing member strip hole also are blade; On the seat of nook closing member, insert pump bowl.This utility model is also implemented by following measure: the overall diameter of nook closing member body is consistent with the interior diameter of needle guard body, the length in the strip hole on needle guard and the nook closing member is 0.7-1.0cm, the wide 1/3-1/2 that is respectively needle guard and nook closing member body, the sword plane of needle guard strip hole two vertical edge blades is in the inboard, the sword plane of nook closing member strip hole two vertical edge blades presses close to cutting two strip holes of needle guard and nook closing member, two vertical edge swords in the outside when rotated; The needle guard tube wall is provided with paracentesis depth graduation apparatus A, section lower edge deep calibration table B and section upper edge deep calibration table C, to mark the position of the needle point position place degree of depth and section respectively, hand holding handle is all established in needle guard and needle core base end, is respectively equipped with corresponding slot midline position arrow on the hand holding handle; Pump bowl is made of cylindrical shell, piston, piston rod, check valve, valve, valve is located at the outside of piston, when piston outside cylindrical shell during pull, valve-closing, check valve are located at the end of the insertion needle core base of cylindrical shell, are non-return valve, when the outside pull of piston, be opening, when piston inwardly pushes, be closed condition.When using this utility model, during the puncture inserting needle, nook closing member is inserted in the needle guard, and be inserted into the end, and rotation nook closing member, make nook closing member strip hole opposite with needle guard strip hole site, this moment, two strip holes all were plugged, and were inserted into and required the degree of depth, and behind the aligning slice position, rotate nook closing member again, alignd with needle guard strip hole in nook closing member strip hole, spur the pump bowl piston rod again and bleed, the tumor soft tissue is inhaled in the nook closing member tube chamber, when piston rod draws when motionless, rotatable nook closing member, the sword limit in nook closing member strip hole and needle guard strip hole is to cutting, cut tissue, the tissue that cuts sucks in the nook closing member tube chamber, if continuous sampling, but repetitive operation.
Beneficial effect: compare with the biopsy needle of present use, this biopsy needle is simple in structure, can continuous sampling before operation, sampling is complete, accurate and expense is low, patient is painful few.
