The using method following (obtaining lump tissue specimen) of this utility model (not comprising puncture needle and Puncture needle sleeve bobbin):
1) after in the time doing percutaneous puncture, CT locates in advance, measure the angle number of degrees (being made as a degree) of intending inserting needle direction and horizontal plane, lump is apart from the degree of depth (being made as b centimetre) of skin, and on patient skin, marks and intend point of puncture and the horizontal line (c line) through this point.
2) the aiming sleeve rotating of puncture locator (a degree) on the corresponding angle of protractor.
Base is placed on to (c line) on horizontal line, makes the edge of base and horizontal line overlapping, aim at the front end of sleeve pipe and aim at point of puncture, adjust base simultaneously, make the bubble of base level indicator be positioned at mid point.
3) rotary protractor makes the bubble of protractor level indicator be positioned at mid point, even if 0 degree line of protractor is on horizontal plane, aims at sleeve angle and is located;
4) existing puncture biopsy needle is entered from aiming sleeve pipe after positioning, can accurately arrive knub position, puncture biopsy needle just can extract lump tissue specimen.
The using method following (obtaining lump tissue specimen) of this utility model (comprising puncture needle and Puncture needle sleeve bobbin):
1) after in the time doing percutaneous puncture, CT locates in advance, measure the angle number of degrees (being made as a degree) of intending inserting needle direction and horizontal plane, lump is apart from the degree of depth (being made as b centimetre) of skin, and on patient skin, marks and intend point of puncture and the horizontal line (c line) through this point.
2) the aiming sleeve rotating of puncture locator (a degree) on the corresponding angle of protractor.
Base is placed on to (c line) on horizontal line, makes the edge of base and horizontal line overlapping, aim at the front end of sleeve pipe and aim at point of puncture, adjust base simultaneously, make the bubble of base level indicator be positioned at mid point.
