Abstract

The utility model discloses a tumor tissue functional puncturing biopsy device, which consists of a puncturing needle 1, a puncturing needle casing pipe 2, and a puncturing needle casing pipe holder 3; wherein, the puncturing needle 1 comprises a small hollow needle pipe 4 and a sliding bar 5; the small hollow needle pipe 4 penetrats through the central circular hole inside the circular cylinder plastic mechanism 12, the upper part of which is connected with an negative pressure cartridge 6 that is provided with a piston 7 and a piston 8. The center of the piston 8 is a hollow cavity, and the sliding bar 5 passes through the central hollow cavity of the piston 8 and then integrated together with the small hollow needle pipe 4. The upper part of the piston 8 has a ring-shaped piston handle 9 and the upper part of the sliding bar 5 has a circular push and pull handle 10. The connecting place between the small hollow needle pipe 4 and the sliding bar 5 has an air discharging hole13. The top part of the small hollow needle pipe 4 is symmetrically provided with two sampling side holes 11 and 11(1). The tumor tissue functional puncturing biopsy device has the advantages of simple structure, convenient application, accurate tissue cutting operation and thus can be widely used for treating the tumor.

Description

Tumor tissues aspiration biopsy device
Technical field
This utility model relates to a kind of utensil that obtains pathological tissues, particularly a kind of tumor tissues aspiration biopsy device.
Background technology
Tumor is a kind of common frdquently encountered disease, makes a definite diagnosis character, position, the scope of tumor accurately, and is significant to tumor treatment.The method of making a definite diagnosis tumor at present has two kinds, and the one, undertaken by sight glass, but have certain limitation, be difficult to reach diseased region at sight glass in some cases, cause difficulty to diagnosis; Another kind is to extract portion of tissue with the aspiration biopsy pin, this pin belongs to the hook-type pin, during use hook-type is needled into lesions position, then it is extracted out, the crotch of its front end can go out the portion of tissue hook in the focus, though this biopsy needle uses for many years, result of use is not ideal enough, and organizing of taking-up often is not lesion tissue.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, easy to operate, accurate positioning, less and can cut the tumor tissues aspiration biopsy device of two position tissues simultaneously to patient trauma.
For reaching above purpose, the technical scheme that this utility model adopted is: this tumor tissues aspiration biopsy device, by puncture needle, the puncture needle sleeve pipe, puncture needle sleeve pipe holder constitutes, its puncture needle comprises thin hollow needle tubing and slide bar, thin hollow needle tubing passes the center hole of cylinder plastic body, so that thin hollow needle tubing is unlikely crooked when sliding up and down, connect negative pressure cylinder on the top of cylinder plastic body, be provided with piston and piston rod in the negative pressure cylinder, the center of piston rod is a cavity, cavity and thin hollow needle tubing that slide bar passes the center of piston rod are connected to an integral body, establish the annular piston handle on the top of piston rod, establish circular push-pull handle in the upper end of slide bar, establish aspirating hole, establish symmetric two sampling side openings in the end of thin hollow needle tubing at thin hollow needle tubing and slide bar junction.This utility model is also implemented by following measure: described two sampling side openings, before it front of sampling side opening along when drawing in the position of puncture needle sleeve pipe with puncture needle sleeve pipe front along concordant, so that the front of preceding sampling side opening along with the front of puncture needle sleeve pipe along forming to cutting, the front of back sampling side opening can cut the tissue of two different depths or different directions simultaneously along concordant with the back edge of preceding sampling side opening; Described cylinder plastic body and negative pressure cylinder are connected to an integral body, also indicate the paracentesis depth reference mark on slide bar, cut the degree of depth to determine tissue, also indicate the labelling projection of puncture needle sampling side opening opening direction on circular push-pull handle.When using this utility model, earlier according to CT, X-ray or other inspection methods, determine the degree of depth of neoplastic lesion position apart from body surface, determine the puncture needle depth of needle with tumor apart from the degree of depth of body surface, and determine sampling side opening opening direction, and after skin treatment, inserting needle vertically, determine that according to the scale on the slide bar needle point is when arriving the tumor center position, press drop shot, make two sampling side openings expose the puncture needle sleeve pipe, spur piston again, make and form negative pressure in the negative pressure cylinder, the tumor tissues of two different depths is sucked into the sampling side opening simultaneously, spurs slide bar again, and thin hollow needle tubing is retracted in the puncture needle sleeve pipe, when retraction, in tumor tissues incision sampling side opening.
The beneficial effects of the utility model are: compare with the biopsy instrument of present use, and simple in structure, easy to use, organize stripping and slicing accurate, and cut the tissue at two positions of different depth simultaneously.
