Abstract
The utility model provides a myeloid biopsy needle which characterized in that: myeloid biopsy needle, including the needle cover, inner syringe, the axial adjust knob that stretch out and draw back, the adjusting sleeve, has the handle of negative pressure cavity, negative pressure pipeline switch by fixed set, wherein: inner syringe lies in the inside of needle cover, and the needle cover is connected with the adjusting sleeve, and inner syringe's well upper portion and the flexible adjust knob of axial are connected, and the flexible adjust knob of axial is connected with the handle that has the negative pressure cavity through fixed cover with adjusting sleeve cooperation, adjusting sleeve, inner syringe communicates through negative pressure pipeline switch and the handle that has the negative pressure cavity. The utility model discloses an advantage: myeloid biopsy needle, principle simple structure makes and convenient to use, depth of inter fit and collection volume that effective control marrow was gathered are convenient for operate.
Description
Technical field
This utility model relates to device for collecting marrow, particularly a kind of myeloid biopsy needle.
Background technology
, there is insertion depth in existing myeloid biopsy needle, problem completely by virtue of experience, and the degree of depth is not easy to control, and simultaneously to the collection capacity of bone marrow, is difficult to reach demand, often only according to penetrate in needle tubing a bit, be unfavorable for effective collection of bone marrow.
Utility model content
The purpose of this utility model is for the ease of bone marrow collection, and spy provides a kind of myeloid biopsy needle.
This utility model provides a kind of myeloid biopsy needle, it is characterized in that: described myeloid biopsy needle, comprises needle guard 1, inner needle tube 2, axial stretching adjusting knob 3, adjusting sleeve 4, fixed cover 5, with the handle 6 of negative pressure cavity, and negative pressure line switch 7;
Wherein: inner needle tube 2 is positioned at the inside of needle guard 1, needle guard 1 is connected with adjusting sleeve 4, the middle and upper part of inner needle tube 2 is connected with axial stretching adjusting knob 3, and axial stretching adjusting knob 3 coordinates with adjusting sleeve 4, and adjusting sleeve 4 is connected with the handle 6 with negative pressure cavity by fixed cover 5; Inner needle tube 2 is communicated with the handle 6 with negative pressure cavity by negative pressure line switch 7.
The rotation of axial stretching adjusting knob 3, can drive relative sliding between inner needle tube 2 and needle guard 1.
Described needle guard 1 outside is with scale.
Described adjusting sleeve 4 is tubular structure, and medium position caliber is less than the caliber at upper and lower two ends.
Advantage of the present utility model:
Myeloid biopsy needle described in the utility model, theory structure is simple, manufactures and easy to use, effectively the insertion depth of control bone marrow collection and collection capacity, convenient operation.
Accompanying drawing explanation
Below in conjunction with drawings and the embodiments, this utility model is described in further detail:
Fig. 1 is myeloid biopsy needle structural representation.
