Abstract
The utility model relates to a myeloid biopsy needle tube, which is composed of a needle tube seat (1) and a needle tube body (2) arranged on the needle tube seat (1). The front end of the needle tube body (2) is provided with a spiral cutting blade (3). The inner tube walls of the front end of the needle tube body are provided with spiral flutes (4). The needle tube body matches with the needle core of a myeloid biopsy needle and connecting columns to form the myeloid biopsy needle. The utility model is used for extracting myeloid tissue in myeloid living tissue examinatin operations. The utility model has the advantages that the biopsy tissue is not easy to shed, the utility model improves success rate, and the utility model relieves patients' pain and economic burden.
Description
This utility model belongs to medical instruments field, particularly a kind ofly is used for the apparatus that the bone marrow biopsy is used.
The bone marrow biopsy needle tubing that uses connects the post coupling with myeloid biopsy needle nook closing member and myeloid biopsy needle and forms myeloid biopsy needle at present, is used for bone marrow biopsy art and extracts myeloid tissue.This bone marrow biopsy needle tubing is made up of needle tubing seat and the needle tube body that is installed on the needle tubing seat, and the needle tube body front end has the spiral cutting sword.Because the needle tube body inner hole wall is smooth, and the myeloid tissue of rotary-cut sometimes in needle tubing comes off, be difficult for taking out in the use.Especially osteoporotic case, the myeloid tissue basilar part of rotary-cut are difficult for being twisted off, and myeloid tissue slippage when extracting needle tubing causes the failure of bone marrow biopsy art.
The purpose of this utility model is to overcome the above-mentioned deficiency of existing bone marrow biopsy apparatus, a kind of myeloid biopsy needle needle tubing of biopsy difficult drop-off is provided, connect the post coupling with bone marrow biopsy nook closing member and myeloid biopsy needle, form myeloid biopsy needle, improve the success rate of bone marrow biopsy art, thereby alleviate patient's misery and financial burden.
This utility model is to realize by the improvement to existing myeloid biopsy needle needle tubing, promptly has helical groove on this needle tubing front end inner hole surface.
Accompanying drawing 1 is this utility model structural representation.
Accompanying drawing 2 is part sectioned views that this utility model front end amplifies.
Be described further below in conjunction with accompanying drawing:
The utility model needle tubing forms needle tube body [2] by needle tubing seat [1] and the needle tube body [2] that is installed on the needle tubing seat [1] Front end has spiral cutting sword [3], has helical groove [4] on needle tube body [2] the front end inner tubal wall.
This utility model is compared with existing bone marrow biopsy apparatus, has the not eely advantage of biopsy, thereby improves the success rate that art is checked in the myeloid tissue biopsy.
Embodiment of the present utility model improves to form on the basis of the B65-01 myeloid biopsy needle that commercially available Shanghai entry needle factory makes.Particularly be exactly to implement the technical pattern that this utility model provides, on needle tube body [2] the front end inner hole wall of B65-01 marrow puncture needle, have helical groove [4].The pitch of the helical groove of present embodiment [4] is 1 millimeter, and groove depth is 0.15 millimeter, and length is 5 millimeters.The use operation of present embodiment, identical with conventional bone marrow biopsy art.The patient packs nook closing member into and rotates inserting needle behind the needle tubing, extracts nook closing member when reaching medullary cavity, connects upper joint pin and reinstalls nook closing member, and after the inserting needle that turns clockwise reached desired depth, still myeloid biopsy needle was extracted in the clockwise direction rotation, takes out the myeloid tissue of adopting.
Claims (1)
1. myeloid biopsy needle needle tubing is made up of needle tubing seat [1] and the needle tube body [2] that is installed on the needle tubing seat [1], and needle tube body [2] front end has spiral cutting sword [3], it is characterized in that having helical groove [4] on needle tube body [2] the front end inner tubal wall.
