Description

Novel bone marrow biopsy puncture

Technical field

The utility model relates to medical apparatus technical fields, specially novel bone marrow biopsy puncture.

Background technique

In clinical diagnosis technology operation, bone marrow aspiration inspection can succeed in most of patient, but if encounter " dry tap " phenomenon, that is, when can not taking out bone marrow fluid, can not just diagnose, such case sees myelosclerosis, myelofibrosis Caused by the bone marrow neoplasms of (primary or secondary), especially malignant tumour (as breast cancer, lung cancer, prostate cancer and gastric cancer etc.) Myelofibrosis and certain leukaemia (such as hairy cell leukemia), the bone marrow puncture of Lymphoma cannot often succeed, It just can make up for it the deficiency of bone marrow puncture using bone marrow biopsy art, and biopsy extraction is big, not only will appreciate that thin in marrow Born of the same parents' ingredient, and it is able to maintain bone marrow structure, malignant cell is easier to recognize, and is convenient for pathological diagnosis, and the also diagnosis of some diseases needs Understand myeloid tissue structure, such as alpastic anemia, myelodysplastic syndrome, malignant tumour marrow transfer etc. just needs Myelopathy Neo-Confucianism inspection is wanted, the understanding how many to alpastic anemia marrow hemopoiesis tissue of bone marrow biopsy art has the certain significance； In addition, biopsy is also significant to the judgement of bone marrow necrosis or fatty marrow.

Clinical Bone Marrow biopsy concrete operations at present are as follows: after routine disinfection anesthesia, left hand thumb and index finger press fixed wear Skin at thorn, the right hand hold needle, rotate inserting needle, until sclerotin certain depth and after fixing, extracts needle core, connect upper joint pin, be inserted into needle About 1 centimetre of inserting needle or so along clockwise direction after core, original position rotates 360 deg, still exits puncture in the direction of the clock Needle, there are following problems in operation for the puncture of this bone marrow biopsy: one, needing in normal clinical manipulation in sterile operating area It puts: the aseptic materials such as marrow puncture needle, myeloid biopsy needle, anesthesia syringe, the empty needle of marrow aspiration and gauze, mesh The preceding myeloid biopsy needle clinically used is connect column and is shorted column and formed totally four parts by needle core, needle tubing, length, building block mistake It is more, it is easy to stab patient skin or is easy to cause pollution because aseptic material placement area is narrow, two, in normal clinical manipulation In be frequently encountered fat patient, the very big strength of left hand is pressed the skin of fixed puncture, is clinically used at present When myeloid biopsy needle operates, after inserting needle is to sclerotin certain depth and fixes, needle core is extracted, upper joint pin is connect, it is above-mentioned to pull out needle The operation that core and installation connect column needs right-hand man to cooperate to carry out, and the fat deposit of patient is no longer squeezed fixation at this time, is easy to consolidate Fixed needle tubing loosely squeezes down, and leads to operation failure, and three, often have doctor living using marrow at present clinically in clinical manipulation Inspection puncture needle not only will firmly rotate the handle of puncture needle when exiting puncture needle in the clockwise direction, while before also holding with a firm grip most The needle tubing at end is easy to cause operation failure since palm area is smaller, so it is next to propose a kind of novel bone marrow biopsy puncture It solves the problems, such as set forth above.
