Abstract
The utility model relates to a novel breast tissue biopsy device, and belongs to the field of medical equipment. The novel breast tissue biopsy device is composed of a sleeve needle 1 and a biopsy knife 2. The novel breast tissue biopsy device is characterized in that the biopsy knife 2 is composed of a knife head 3, a knife rod 4 and a knife handle 5. A knife edge 6 is arranged on the side face of the knife head 3, and a barb 7 is arranged at the top end of the knife head 3. The novel breast tissue biopsy device is simple in structure, convenient to use, and ideal, and can be used for breast tissue biopsy, fetched tissue blocks are large, the novel breast tissue biopsy device slightly extrudes cells, and therefore accuracy of diseased tissue biopsy diagnosis can be improved.
Description
Technical field: this utility model belongs to medical instruments field, be particularly related to a kind of biological tissue that can be used for mammary gland and get inspection, the piece of tissue of taking out is large and lighter to cell extruding, contributes to improve the new breast tissue biopsy device of pathological tissues biopsy diagnosis accuracy rate.
Background technology: in Breast Surgery clinical position, often will carry out biological tissue to some supramammary not clear lumps and get inspection, then do pathologic finding, determine the character of this lump, then determine modus operandi.At present, for the biopsy mode of mammary gland tissue, mainly rely on operation to get inspection clinically and fine needle aspiration pin suction cytology checks two kinds of methods, if adopt operation, get the mode of inspection, on not clear lump, cut part tissue, then do pathologic finding, the damage bringing to patient is larger, and because this lump character is uncertain, if malignant tumor, by getting, examine the stimulation that operation brings, will cause this tumor quickening diffusion, increase patient's misery, if adopt fine needle aspiration, aspirate this lump part cell, then do the mode of cytolgical examination, easily push cell, make cytomorphosis, cause the Misdiagnosis to this lump, the best occasion for the treatment of having incured loss through delay patient, to patient with serving unnecessary loss and misery, cause a series of medical tangle, to medical worker, bring unnecessary trouble.
Summary of the invention: the purpose of this utility model is to provide a kind of biological tissue that can be used for mammary gland to get inspection, the piece of tissue of taking-up is large and lighter to cell extruding, contributes to improve the new breast tissue biopsy device of pathological tissues biopsy diagnosis accuracy rate.
For achieving the above object, this utility model has been taked following technical scheme: this new breast tissue biopsy device, by the trocar and get inspection cutter form, get inspection cutter by cutter head, knife bar and handle of a knife, formed, the side of cutter head is provided with blade, the top of cutter head is provided with barb.
This utility model, simple in structure, easy to use, the biological tissue that can be used for mammary gland is got inspection, and the piece of tissue of taking-up is large and lighter to cell extruding, contributes to improve the accuracy rate of pathological tissues biopsy diagnosis, is a kind of desirable mammary gland tissue biopsy device.
Accompanying drawing explanation: the utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present utility model.
With reference to accompanying drawing 1,1, the trocar, 2, get inspection cutter, 3, cutter head, 4, knife bar, 5, handle of a knife, 6, blade, 7, barb.
The specific embodiment: this utility model, by the trocar 1 with get inspection cutter 2 and form, to get inspection cutter 2 and formed by cutter head 3, knife bar 4 and handle of a knife 5, the side of cutter head 3 is provided with blade 6, and the top of cutter head 3 is provided with barb 7.
While using this utility model, first by the trocar 1 with get inspection cutter 2 and together penetrate in breast tumor, grasp handle of a knife 5, with blade 6 target location rotary-cut one week, with barb 7, catching on piece of tissue again takes out through the trocar 1, then the piece of tissue of taking-up is put in the Specimen bottle that formalin fixative is housed, delivered to Pathology Deparment's laboratory examination.
