Abstract

The utility model relates to an iliac puncture and iliac bone biopsy dual-purpose puncture needle which comprises a needle core (1) and a needle guard (2). A needle guard handle (3) is arranged on the needle guard (2). The iliac puncture and iliac bone biopsy dual-purpose puncture needle is characterized in that a tubular biopsy needle (4) is arranged between the needle core (1) and the needle guard (2), threads are oppositely arranged on the outer surface of the biopsy needle (4) and the inner surface of the needle guard (2), and the needle guard (2) is sleeved on the biopsy needle (4) in a threaded manner; a knife edge (5) in the shape of a circular hole is arranged at the front end of the biopsy needle (4), and a biopsy needle handle (6) is arranged at the tail end of the biopsy needle (4). The iliac puncture and iliac bone biopsy dual-purpose puncture needle has the advantages that the iliac puncture and iliac bone biopsy dual-purpose puncture needle is reasonable in structure and brings convenience for surgery, the needle insertion depth is accurate, cytological examination and biopsy can be completed by means of puncture at one step, the puncture success rate can be increased, precious time can be saved, suffering of patients can be relieved, and tension of the patient can be eased.

Description

Ilium is worn and ilium biopsy dual purpose puncture needle

Technical field

This utility model belongs to the medical apparatus technical field, relates in particular to medullary cell in a kind of ilium paracentesis and learns and bone marrow biopsy dual purpose puncture needle.

Background technology

During the clinical definite disease in the blood system, the ilium puncture is most important and most basic inspection item, and the purpose of marrow cell coating plate is judgement nucleated cell hyperplasia degree, calculates percentage rate, form, quantity and the distribution situation of various types of cells.And being the cylindrical bone myeloid tissue of getting about 0.5～1 centimeter length of a fritter, bone marrow biopsy does the pathology inspection.The material taken out has kept complete myeloid tissue structure, can make up the deficiency of bone marrow aspiration.Not only can understand composition and the germinal cell distribution situation of medullary cell, and energy observation of cell form, be convenient to make pathological diagnosis.The single bone marrow aspiration of some disease (as: leukemia) just can be made a definite diagnosis, and the diagnosis of some disease (as: myelodysplastisches disease, aplastic anemia, myelofibrosis etc.) need to just can be made a definite diagnosis in conjunction with bone marrow biopsy.Although in clinical manipulation, two inspections are often carried out at present, are the different puncture needles of two covers, need successively twice puncture, have increased patient's wound and misery simultaneously.And at present ilium mostly is in wearing that range estimation estimates the degree of depth of inserting needle, inserting needle cross dark or shallowly all can have influence on surgical effect, reduced the successful probability that punctures, increased patient's misery.

Summary of the invention

The purpose of this utility model is to provide a kind of depth of needle that guarantees, only carries out the dual purpose puncture needle that one-time puncture can complete medullary cell and bone marrow biopsy.Realize that the technical scheme that the purpose of this utility model is taked is: this dual purpose puncture needle includes nook closing member and needle guard, needle guard is provided with the needle guard handle, be provided with the tubulose biopsy needle between nook closing member and needle guard, the outer surface of biopsy needle and the inner surface of needle guard are oppositely arranged screw thread, utilize screw thread that needle guard and biopsy needle are set in together; The front end of biopsy needle is provided with the circle hole shape edge of a knife, the end of biopsy needle is provided with the biopsy needle handle, be respectively equipped with paracentesis depth scale and biopsy deep calibration on said needle guard and biopsy needle, coordinate and be provided with locating ring with scale on needle guard, locating ring is tightly placed on needle guard and can promotes on needle guard, is positioned to be convenient to the healthcare givers on certain scale and to observe depth of needle.

This utility model is rational in infrastructure, facilitating operation, and depth of needle is accurate, and cytology and biopsy can be punctured and once be completed, and have improved puncture success rate, have saved the quality time, have alleviated patient's misery, have alleviated patient's intense strain.

The accompanying drawing explanation

Fig. 1 is contour structures schematic diagram of the present utility model;

Fig. 2 is sectional structure schematic diagram of the present utility model;

Fig. 3 is the knife edge structure schematic diagram of biopsy needle in this utility model.

In figure, 1, nook closing member, 2, needle guard, 3, the needle guard handle, 4, biopsy needle, 5, the edge of a knife, 6, the biopsy needle handle, 7, the paracentesis depth scale, 8, the biopsy deep calibration, 9, locating ring, 10, the biopsy needle end port.

The specific embodiment

With reference to accompanying drawing, a kind of ilium is worn and ilium biopsy dual purpose puncture needle, include nook closing member 1 and needle guard 2, needle guard 2 is provided with needle guard handle 3, be provided with tubulose biopsy needle 4 between nook closing member 1 and needle guard 2, the inner surface of the outer surface of biopsy needle 4 and needle guard 2 is oppositely arranged screw thread, utilizes screw thread that needle guard 2 and biopsy needle 4 are set in together; The front end of biopsy needle 4 is provided with the circle hole shape edge of a knife 5, the end of biopsy needle 4 is provided with biopsy needle handle 6, be respectively equipped with paracentesis depth scale 7 and biopsy deep calibration 8 on described needle guard 2 and biopsy needle 4, coordinate and be provided with locating ring 9 with paracentesis depth scale 7, locating ring 9 is tightly placed on needle guard 2 and can promotes on needle guard 2, is positioned to be convenient to the healthcare givers on certain scale and to observe depth of needle.During use, locating ring 9 is located on the scale that needs paracentesis depth, the healthcare givers holds needle guard handle 3 and biopsy needle handle 6 simultaneously, after the puncture certain depth, takes out nook closing member 1, with the dry injection device, extracts the censorship of 0.1-0.2ml bone marrow smear.Seal biopsy needle end port 10 with pipe cap simultaneously.During biopsy, one to hold needle guard handle 3 motionless, another hands clockwise rotates biopsy needle handle 6 biopsy needle 4 is continued to inserting needle 1-2cm, then rotation limit, limit withdraws needle guard 2 together with biopsy needle 4 simultaneously, insert probe from biopsy needle end port 10, and gently by the complete extrapolation of specimen in the biopsy needle front end edge of a knife 5, biopsy specimen is generally fixed by formalin.Any special examined scheme all need be formulated before bone marrow aspiration, is convenient to biopsy specimen is done to special handling.This utility model can be located depth of needle, and, after inserting needle, needle guard 2 maintains static, and biopsy needle 4, in the interior propelling of needle guard 2, extracts biopsy specimen, has greatly improved puncture success rate, has alleviated patient's misery.
