Abstract
The utility model discloses a tumour biopsy sampling unit. The sampling unit comprises a puncture needle tube, wherein a cylindrical operating handle is arranged at the rear end of the puncture needle tube, an opening through hole communicated with the inner part of the puncture needle tube is arranged in the operating handle, and rings are symmetrically arranged at the two sides of the rear end of the outer wall of the operating handle; a sampling bar is arranged in the puncture needle tube, the rear end of the sampling bar penetrates through the operating through hole and extends to the outer part of the operating handle, triangular pyramid cutting tool bits are symmetrically arranged at the two sides of the front end of the sampling bar and an outer thread is arranged on the outer wall of the rear end of the sampling bar; a limit block is connected on the outer thread in a threaded way, the rear end of the sampling bar is connected with a cylindrical operating cap in a threaded way, and antiskid protuberances are uniformly arranged on the outer wall of the operating cap. The sampling unit provided by the utility model is simple in structure, convenient to use, is capable of preventing the success ratio of the biopsy sampling, and preventing the pain in patients due to repetitive operation.
Description
Technical field:
This utility model relates to biopsy sampler tool, particularly a kind of tumor biopsy sampler.
Background technology:
At present, oncology is in the time of sampling biopsy, need to use the puncture biopsy needle being formed by needle tubing and nook closing member, the body lower end of needle tubing used is inclined-plane opening, in the time that needle point arrives the sampling of sample position extraction nook closing member, differ and effectively obtain surely biopsy, affect the accuracy of biopsy, or repetitive operation brings more misery to patient.
Summary of the invention:
The purpose of this utility model is to overcome the shortcoming existing in prior art, provides a kind of simple in structure, easy to use and improve the tumor biopsy sampler of biopsy sampling success rate.
To achieve these goals, this utility model provides a kind of tumor biopsy sampler, comprise puncture needle tubing, wherein, the rear end of described puncture needle tubing is provided with cylindrical operating grip, the inside of described operating grip is provided with the operation through hole with described puncture needle tubing internal communication, the outer wall rear end lateral symmetry of described operating grip is provided with semicircle annular or annular finger ring, the inside of described puncture needle tubing is provided with thief rod, the rear end of described thief rod extends to the outside of described operating grip through described operation through hole, the front end lateral symmetry of described thief rod is provided with Rhizoma Sparganii taper cutter head, on the rear end outer wall of described thief rod, be provided with external screw thread, limited location piece is threaded on described external screw thread, the rear end end thread of described thief rod is connected with cylindrical operation cap, on the outer wall of described operation cap, be evenly provided with non-slip process.
This utility model outstanding advantages is: simple in structure, when use, the degree of depth of puncture as required, sampling number etc. concrete condition, limited block is adjusted to correct position, then proficiency hand-held operation hands handle, puncture needle tubing is probeed into and punctured, then another hands pinches operation cap, promote downwards to drive after the cutting downwards of triangular pyramid cutter head, at least one week of rotating operation cap, drive triangular pyramid cutter head transverse cuts, thereby sampling part is cut down and is trapped in puncture needle tubing, finally hold will puncture needle tubing pull-out of operating grip, easy to use, can greatly improve the success rate of biopsy sampling, the misery of avoiding repetitive operation to bring to patient.
Accompanying drawing explanation:
Fig. 1 is the overall structure front view of this utility model embodiment.
Fig. 2 is the enlarged drawing of overlooking of Fig. 1.
The specific embodiment:
When embodiment of the present utility model implements, design agents mechanism comprises puncture needle tubing 1, cutter head 2, thief rod 3, operating grip 4, external screw thread 5, finger ring 6, operation cap 7, non-slip process 8, operation through hole 9 and limited block 10.Its technical scheme is: a kind of tumor biopsy sampler, comprise puncture needle tubing 1, wherein, the rear end of puncture needle tubing 1 is provided with cylindrical operating grip 4, the inside of operating grip 4 is provided with the operation through hole 9 with needle tubing 1 internal communication that punctures, the outer wall rear end lateral symmetry of operating grip 4 is provided with semicircle annular finger ring 6, the inside of puncture needle tubing 1 is provided with thief rod 3, the rear end of thief rod 3 extends to the outside of operating grip 4 through operation through hole 9, the front end lateral symmetry of thief rod 3 is provided with Rhizoma Sparganii taper cutter head 2, on the rear end outer wall of thief rod 3, be provided with external screw thread 5, limited location piece 10 is threaded on external screw thread 5, the rear end end thread of thief rod 3 is connected with cylindrical operation cap 7, on the outer wall of operation cap 7, be evenly provided with non-slip process 8.
The outer wall rear end lateral symmetry of operating grip 4 is provided with semicircle annular finger ring 6, is convenient to grip, and is difficult for slippage.
The front end lateral symmetry of thief rod 3 is provided with Rhizoma Sparganii taper cutter head 2, be that cutter head 2 has a longitudinal cutting edge and two transverse cuts blades, thereby can be after puncturing successfully, first utilize longitudinal cutting edge of cutter head 2 that the tissue in puncture needle tubing 1 is longitudinally cut, make cutter head 2 move to the front end of puncture needle tubing 1, then utilize the rotation of two transverse cuts blades of cutter head 2, sampling part in puncture needle tubing 1 is cut down, be trapped in puncture needle tubing 1, thereby guarantee the success rate sampling.
On the rear end outer wall of thief rod 3, be provided with external screw thread 5, limited location piece 10 is threaded on external screw thread 5, can, by controlling the position of limited block 10 on thief rod 3, control the position of the front cutting cutter head 2 of thief rod 3, thereby can control length or the degree of depth of the sample of cutting.
