In this utility model, the afterbody of described interior pin needle tubing is provided with interior pin handle, pin in convenient control, aspirate tissue.
In this utility model, described interior wire surface is provided with burr sampling structure, or interior pin wall is provided with inverted triangle sample tap or screw thread rectangular groove structure sample tap, the convenient tissue of disturbing, efficient sampling fast.
In this utility model, described outer pin handle end is made as female Luer structure, for connecting syringe after interior pin locking cap dismounting, facilitates the tissue of draw sufficient.
This utility model is considered the situation of prior art, and applicant thinks can reliably obtain enough tissues by a kind of sampling probe of necessary design accurately, time saving and energy saving.
Beneficial effect: this utility model is simple in structure, is easy to processing, and assembly method and using method and biopsy needle are on the market substantially similar, is convenient to study and uses, and this utility model is not subject to size and structural limitations, obtains tissue accurately convenient, and sampling amount is large, time saving and energy saving.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, this utility model is done further and illustrated, the advantage of above and other of the present utility model aspect will become apparent.
Fig. 1 is a kind of structural representation of sampling probe;
Fig. 2 a～Fig. 2 c is multiple interior needle construction schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is elaborated.
As Fig. 1, comprise interior pin 1, outer pin 2, interior pin needle tubing 3, outer pin needle tubing 5, trocar sheath 4, trocar sheath handle 6, outer pin sealing ring 7, outer pin locking cap 8, outer pin screwed hole 9, outer pin handle 10, interior pin screwed hole 12, interior pin sealing ring 14, interior pin locking cap 11, interior pin handle 13 and female Luer 15, pin needle tubing 3 in interior pin end connects, outer pin end connects outer pin needle tubing 5, interior pin 1 and interior pin needle tubing 3 overlap pin 2 and outer pin needle tubing 5 the insides outside, outer pin needle tubing 5 is enclosed within trocar sheath 4 the insides, trocar sheath 4 near-ends are connected with trocar sheath handle 6, outer pin sealing ring 7 and outer pin locking cap 8 are located on the outer pin needle tubing 5 of trocar sheath handle 6 afterbodys, the near-end of outer pin needle tubing 5 is provided with outer pin handle 10, the end of outer pin handle 10 is provided with female Luer 15, the interior pin needle tubing 5 of outer pin handle 10 afterbodys is provided with interior pin sealing ring 14 and interior pin locking cap 11, and the near-end of interior pin needle tubing 3 is connected with interior pin handle 13, described trocar sheath 4, interior pin needle tubing 3 and outer pin needle tubing 5 are near-end near interior pin handle 13 one end, and outer pin sealing ring 7 and interior pin sealing ring 14 are made by the material of silicone rubber or other compressible elastomeric materials.
When use, first interior pin and interior pin needle tubing are receded into outer pin in outer pin needle tubing, tighten interior pin locking cap and make it to push interior pin sealing ring, the interior pin sealing ring of elastic material be squeezed internal pin needle tubing produce pressure make interior pin needle tubing mutually externally pin needle tubing fix, now interior pin pin pin in-pipe outside, then outer pin and outer pin needle tubing are retracted in trocar sheath, tighten outer pin locking cap and make it fixing, under ultrasonic endoscope monitors, sampling probe is sent into destination organization place, unclamp outer pin locking cap, interior pin is thrust to tissue together with outer pin, then unclamp interior pin locking cap, pin in releasing, the burr structure of pin front portion in utilizing, inverted triangle sample tap or the fly-cutting of screw thread rectangular groove structure, disturb tissue, auxiliary sampling, then interior pin is extracted out, the interior pin hands handle of dismantling, syringe access female Luer, utilize syringe pump tissue, after having sampled, outer pin is return to trocar sheath, fixing outer pin locking cap, exit ultrasonic endoscope, sampling censorship.
