In addition, the descriptions related to "first", "second", etc. in the present invention are for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicit ly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions in the embodiments may be combined with each other, but it must be based on the realization of those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should not be considered to exist, and is not within the protection scope of the present invention.
The utility model provides a puncture sampling device for tumor biopsy. FIG. 1 is a schematic structural view of the puncture sampling device for tumor biopsy of the present invention when the sampling needle is not extended out of the puncture needle; fig. 2 is a schematic structural view of the puncture sampling device for tumor biopsy of the present invention when the sampling needle extends out of the puncture needle.
According to the structure shown in fig. 1 and fig. 2 the utility model discloses a puncture sampling device for tumor biopsy, including sleeve 1, pjncture needle 2 and sampling needle 3, wherein sleeve 1 is circular structure, and pjncture needle 2 fixed connection is at the front end of sleeve 1, and when the operation, the accessible holds sleeve 1 and moves forward and makes pjncture needle 2 pierce the patient internal, can set up the protection line on the sleeve 1, perhaps sets up on the sleeve 1 and holds the ring. In addition, the sampling needle 3 is arranged inside the puncture needle 2, and the sampling needle 3 can move in the axis direction of the sampling needle 3 relative to the puncture needle 2, so that after the puncture needle 2 reaches a sampling position, the sampling needle 3 can extend out of the puncture needle 2 under the pushing action force to perform sampling, and can be retracted into the puncture needle 2 after the sampling is completed, so as to protect the pathological tissue sample after the sampling is completed. Sampling needle 3 can be realized through current needle body structure, is provided with the sample structure that is used for sample or excision tissue piece on sampling needle 3 promptly, and this is prior art, and no longer repeated here.
The puncture sampling device for tumor biopsy of the utility model also comprises a driving mechanism for driving the sampling needle 3 to move relative to the puncture needle 2. The driving mechanism comprises a driving part and a driven part 5, wherein the driving part can be operated to rotate relative to the sleeve 1, and when the driving part is operated to rotate relative to the sleeve 1, the driving part can move relative to the sleeve 1 in the axial direction of the sleeve 1; i.e. the drive member can be operatively rotated by the healthcare worker, and when the drive member is operatively rotated, the drive member will be screwed into the socket 1, i.e. the drive member will rotate relative to the socket 1, but at the same time will move relative to the socket 1 in the axial direction of the socket 1. In particular, the driving member comprises a cylindrical body 4 arranged inside the sleeve 1, a helical groove 8 arranged around the axis of the sleeve 1 is arranged inside the sleeve 1, and an engagement portion 7 is arranged on the cylindrical body 4, the engagement portion 7 being able to walk along the helical groove 8 when the cylindrical body 4 is operatively rotated. In this way the driver forms an approximate screw-threaded fit with the socket 1, unlike a full screw-threaded fit, where the engagement portion 7 corresponds to one turn in the helical groove 8, to reduce the resistance when the driver is rotated. In this case, when the driver is operatively rotated, the engagement portion 7 rotationally travels along the travel path guided by the spiral groove 8.
In addition, a driven piece 5 of the driving mechanism is arranged in the sleeve 1, and the driven piece 5 and the driving piece are in fit connection through a rotating bearing 6, so that the driven piece 5 can be independent of the rotation of the driving piece and can move along the axis direction of the sleeve 1 along with the driving piece; the sampling needle 3 is connected with the passive piece 5. Since the driven member 5 is connected to the driving member via the rotary bearing 6, when the driving member is operatively rotated, the driven member 5 does not rotate following the driving member, but moves following the driving member relative to the socket 1 in the axial direction of the socket 1. That is, the driven member 5 only moves in the axial direction of the hub 1 relative to the hub 1 when the driving member is operated to rotate, so as to move the sampling needle 3 relative to the puncture needle 2, so that, when the puncture needle 2 reaches the sampling position, the sampling needle 3 extends out of the puncture needle 2 under the rotation of the driving member/operating member to perform sampling, and can be retracted into the puncture needle 2 under the rotation of the driving member/operating member after sampling is completed, so as to protect the sampled pathological tissue sample.
In the embodiment shown in fig. 1 and 2, the driving member further comprises an operating member 9 for rotating the column 4, and the operating member 9 is fixedly connected with the column 4. The operating part 9 comprises an operating cap 11 and a connecting rod 10 fixedly connected with the operating cap, the connecting rod 10 is fixedly connected with the column 4, and the operating cap 11 is sleeved outside the sleeve 1. The inner side of the operating cap 11 is in threaded fit with the outer side of the sleeve 1.
In addition, in the embodiment shown in fig. 1 and 2, the driven member 5 is a sleeve structure, and the outer side of the driven member 5 is in spline fit with the inner side of the sleeve 1, so that when the driving member is rotated, the rotation of the driven member 5 around the axis of the sleeve 1 is limited. By the spline fit of the driven member 5 and the sleeve 1, the driven member 5 is further restrained from following the rotation of the driving member when the driving member is rotated.
Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
