Detailed description of the invention
In order to there be understanding clearly to technical characteristic of the present utility model, object and effect, now contrast accompanying drawing and detailed description of the invention of the present utility model is described.
As shown in Figure 1 to Figure 3, what this utility model provided a kind of disposable biopsy needle holds up pin device 10, and this holds up pin device 10 to comprise inner core 101, rubber parts 102 and overcoat 103; It is outside that the front end of overcoat 103 is closed, open rearward end coaxial sleeve are located at inner core 101; The center, front end of inner core 101 is provided with square groove 1011, and rubber parts 102 is square and is embedded in groove 1011; The front end of inner core 101 is resisted against the front end of overcoat 103; Center through inner core, rubber parts and overcoat is provided with the axially extending bore 104 passed through for biopsy needle.Inner core 101 and overcoat 103 are cylinder, for being rotationally connected between inner core and overcoat.The bottom of inner core 101 is provided with the first annular protrusion 1012, overcoat 103 rear end inwall is provided with the first annular groove coordinated with the first annular protrusion 1012, first annular protrusion 1012 is resisted against in the first annular groove, the bottom surface of inner core 101 flushes with the bottom surface of overcoat 103, make the mutual restriction of inner core and overcoat, ensure the safety and effectiveness of press fit arrangement.The inwall of overcoat 103 is provided with the second annular protrusion 1031, the outer wall of inner core 101 is corresponding with the second annular protrusion 1031 is provided with the second annular groove 1013, second annular protrusion 1031 is positioned at the second annular groove 1013, to realize in disposable biopsy needle 20 rotation process, hold up the inner core 101 of pin device 10 can not be separated with overcoat 103, ensure the safe and effective of this structure.Second annular protrusion 1031 rear portion is provided with level and smooth guiding surface, inner core 101 and overcoat 103 all adopt plastic material, have certain elastic deformability, inner core 101 and overcoat 103 can adopt injection mo(u)lding respectively, inner core and overcoat are axially aligned and carry out press fit arrangement.This level and smooth guiding surface can smoothly by the second annular protrusion 1031, thus make the second annular protrusion 1031 snap onto in the second annular groove 1013 when making inner core 101 load overcoat 103.The outer wall of overcoat 103 establishes irregular lines, and person easy to use brings the operation after sterile gloves, avoids skidding.The front end of overcoat 103 is provided with dismounting through hole 1032 around the surrounding of axially extending bore 104, conveniently inner core 101 and overcoat 103 is dismantled.
Further, as shown in Figure 4, this utility model can form an electrical bone biopsy device 1 together with adapter coupling 40, disposable biopsy needle locking device 30, disposable biopsy needle 20 and power drill/driver 50.The outfan of power drill/driver 50 connects disposable biopsy needle locking device 30 by adapter coupling 40, and fixing and locking once property biopsy needle 20 on disposable biopsy needle locking device 30, sheathed this that disposable biopsy needle 20 slides holds up pin device 10.Driven by power drill/driver 50, from bone or osseous tissue, take out sample.Power drill/driver 50 can provide best rotating speed and moment of torsion to obtain biopsy sample to rotate disposable biopsy needle 20.Adapter coupling 40 is combined with disposable biopsy needle locking device 30, to realize the power transmission of power drill/driver 50 and disposable biopsy needle 20.Pin device 10 is held up to slide on disposable biopsy needle 20 and to stop, needle tubing there is scale accurately realize the accurate location of paracentesis depth, inner core 101 and disposable biopsy needle 20 common rotation when this holds up pin device 10 to use, the hand steered overcoat 103 of holding of user keeps not rotating, for user provides a strong strong point, thus enhance the reliability obtaining biopsy sample.
