Abstract

The invention provides a more scientific, convenient and practical appliance for clinical bone marrow biopsy operation and in particular provides a novel bone marrow biopsy puncture needle (drawing 3), belonging to the technical field of medical technology A61M. The appliance is used for transferring media in human bodies or taking out media from human bodies. The puncture needle has the following advantages: 1. the puncture needle is just composed of a needle core and a needle tubing, so the puncture needle can ensure safety of the patients and is easy to put during operation and is not easy to pollute; 2. during normal clinical operation, after the needle is inserted into certain depth of the bone substance and is fixed, the needle core only needs to be withdrawn with the right hand according to the material drawing requirement (the space between salient points is 0.5cm) and then is clamped in a clamp slot and then the needle is inserted clockwise; and 3. the puncture needle is withdrawn clockwise, and as the needle tubing and the needle core are fixed by the clamp slot, the right hand only grips a handle, the most effort-saving part during rotation, to carry out operation; and the whole process can be completed by the doctor with one hand and the operation success rate is greatly improved.

Description

Novel myeloid biopsy needle

One, technical field:

The medical apparatus and instruments that the present invention must use for clinical bone marrow biopsy operation art.Its technical characterstic: to leading to the failure easily in the present clinical myeloid biopsy needle, science and unnecessary parts do not design again, for clinical bone marrow biopsy operation art provides science more, convenience, practical apparatus.

Summary of the invention belongs to Medical Technology A61M: for the transfering human medium or in human body, taking out the apparatus of medium.

Two, background technology

In the clinical diagnosis technology operation, the bone marrow aspiration inspection can be successful in most of patient, if but having run into " dry tap " phenomenon, when promptly can not taking out bone marrow fluid, just can't diagnose.This situation is shown in myelosclerosis; Myelofibrosis (constitutional or Secondary cases); Especially malignant tumor is (as breast carcinoma; Pulmonary carcinoma, carcinoma of prostate and gastric cancer etc.) bone marrow shift due to myelofibrosis and some leukemia (for example hairy cell leukemia), lymphoma patient's bone marrow puncture Chang Buneng success.Adopt the bone marrow biopsy art just can remedy the deficiency of bone marrow puncture, and biopsy draws materials greatly, not only can understand the cell component in the bone marrow, and can keep the bone marrow structure, malignant cell is easy to be familiar with, and is convenient to pathological diagnosis.Also the diagnosis of some disease need be understood the myeloid tissue structure, such as aplastic anemia, and myelodysplastic syndrome, malignant tumor bone marrow transfer etc. just needs the bone marrow pathological examination.What understanding is the bone marrow biopsy art organize have the certain significance to the aplastic anemia bone marrow hematogenesis; In addition, biopsy is also meaningful to the judgement of BMN or fatty marrow.

The concrete operations of present clinical bone marrow biopsy art are: after the routine disinfection anesthesia, left hand thumb and forefinger press fixedly puncture place skin, right hand-held needle; The rotation inserting needle to the sclerotin certain depth and after fixing, is extracted nook closing member; Connect upper joint pin; Insert behind the nook closing member along clockwise direction about about 1 centimetre of inserting needle again, puncture needle is still withdrawed from 360 ° of original position rotations in the direction of the clock.There is following problems in operation in this bone marrow biopsy puncture: 1, in the normal clinical operation, need put at aseptic operating area: aseptic materials such as the empty needle of marrow puncture needle, myeloid biopsy needle, anesthetic syringe, marrow aspiration and gauze.The myeloid biopsy needle (Fig. 1) that uses clinically at present by nook closing member, needle tubing, long connect post and short circuit post totally 4 parts form.Building block is too much, stabs patient skin easily and perhaps causes easily because of the aseptic material placement area is narrow and small polluting.2, in the normal clinical operation, run into fat patient through regular meeting, left hand will press the skin of fixing puncture with very big strength.When the myeloid biopsy needle (Fig. 1) of use is operated clinically at present, when inserting needle to sclerotin certain depth and after fixing, extract nook closing member, connect upper joint pin, the above-mentioned nook closing member that pulls out carries out with the action need right-hand man cooperation that installation connects post.This moment, patient's fat deposit no longer was squeezed fixingly, will fix not firm needle tubing easily and squeeze, and caused operation failure.3, in clinical manipulation, often there is the doctor to use present myeloid biopsy needle (Fig. 1) clinically when withdrawing from puncture needle in the clockwise direction; Not only to firmly rotate the handle of puncture needle; Foremost the needle tubing (not having draw-in groove to fix because connect between post and the needle tubing) of also will holding with a firm grip simultaneously is because the less operation failure that causes easily of palm area.

Three, summary of the invention

Based on above technical background and clinical medical demand, the present invention is a kind of novel myeloid biopsy needle, and we hope to solve difficulty and deficiency in the clinical bone marrow biopsy art through this novel myeloid biopsy needle.Summary of the invention: novel myeloid biopsy needle (Fig. 2,3) only is made up of nook closing member, needle tubing two parts.0.5 centimetre groove is at interval arranged on needle tubing, near the handle place 0.5 centimetre salient point is at interval arranged at nook closing member.

Five, the specific embodiment

Novel myeloid biopsy needle (Fig. 2,3) has following advantage: 1, puncture needle is only by nook closing member, and needle tubing two parts are formed, and when operation, can guarantee patient safety and puts easily, is not easy contaminated.2, in normal clinical operation when inserting needle to sclerotin certain depth and fixing after, only need nook closing member be retreated according to the requirement of drawing materials (0.5 centimetre of each bump pitch) with the right hand, snapping in behind the draw-in groove along clockwise direction then, inserting needle gets final product.3, withdraw from puncture needle in the clockwise direction, because needle tubing and nook closing member have fixing of draw-in groove, the right hand only need be held and rotate labour-saving part---lever operated getting final product.Whole process doctor's one hand can be accomplished, and easy to operate, success rate improves greatly.

Claims

1. novel myeloid biopsy needle, its technical characterictic is: its formation only is made up of nook closing member, needle tubing two parts.0.5 centimetre groove is at interval arranged on needle tubing, near the handle place 0.5 centimetre salient point is at interval arranged at nook closing member.

In normal clinical operation when inserting needle to sclerotin certain depth and fixing after, only need nook closing member be retreated according to the requirement of drawing materials (0.5 centimetre of each bump pitch) with the right hand, snapping in behind the draw-in groove along clockwise direction then, inserting needle gets final product; Withdraw from puncture needle in the clockwise direction, because needle tubing and nook closing member have fixing of draw-in groove, the right hand only need be held and rotate labour-saving part---lever operated getting final product.
