Abstract
The utility model relates to a novel rectal lump biopsy device and belongs to the technical field of medical instruments. The novel rectal lump biopsy device is composed of a rectum expanding tube 1 and a pickup knife 2 and is characterized in that the tail portion of the rectum expanding tube 1 is provided with a horn-shaped tail wing 3, the pickup knife 2 is composed of a knife head 4, a knife bar 5 and a knife handle 6, the side surface of the knife head 4 is provide with a knife edge 7, and the top of the knife head 4 is provided with a barb 8. The novel rectal lump biopsy device is simple in structure and easy to use and can be used for the biopsy of a rectal bump, and a picked tissue block is large with little cell crush, so that the accuracy of the biopsy diagnosis of lesion tissue can be improved. The novel rectal lump biopsy device is an ideal rectal lump biopsy device.
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 rectal mass and get inspection, the piece of tissue of taking out is big and lighter to the cell extruding, helps to improve the novel rectal mass biopsy device of pathological tissues biopsy diagnosis accuracy rate.
Background technology: in the surgery clinical position, often to carry out biological tissue to the not clear lump of some rectum and get inspection, do pathologic finding then, determine the character of this lump, determine modus operandi then, and often there is degeneration necrosis on the surface of rectal mass, and present employed biopsy forceps can only be stung the tissue of getting lump table superficial part position, the accuracy of influence diagnosis.If adopt the mode of operation, cut part tissue at not clear lump, do pathologic finding then, the damage that brings to the patient is bigger, and because this lump character is uncertain, if malignant tumor, by getting the stimulation that the inspection operation brings, will cause this tumor quickening diffusion, increase patient's misery.Aspirate this lump part cell if adopt fine needle aspiration, do the mode of cytolgical examination then, push cell easily, make cytomorphosis, cause the mistaken diagnosis of this lump is failed to pinpoint a disease in diagnosis, incured loss through delay patient's best occasion for the treatment, bring some unnecessary loss and misery to the patient, cause a series of medical tangle, bring unnecessary trouble to the medical worker.
Summary of the invention: the purpose of this utility model is to provide a kind of biological tissue that can be used for rectal mass to get inspection, and the piece of tissue of taking-up is big and lighter to the cell extruding, helps to improve the novel rectal mass biopsy device of pathological tissues biopsy diagnosis accuracy rate.
For achieving the above object, this utility model has been taked following technical scheme: this novel rectal mass biopsy device, by the proctectasia tube and get the inspection cutter constitute, the afterbody of proctectasia tube is provided with tubaeform empennage, getting the inspection cutter is made of cutter head, knife bar and handle of a knife, the side of cutter head is provided with blade, and 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 rectal mass is got inspection, and the piece of tissue of taking-up is big and lighter to the cell extruding, helps to improve the accuracy rate of pathological tissues biopsy diagnosis, is a kind of desirable rectal mass biopsy device.
Description of drawings: 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, proctectasia tube, 2, get the inspection cutter, 3, empennage, 4, cutter head, 5, knife bar, 6, handle of a knife, 7, blade, 8, barb.
The specific embodiment: this utility model, by proctectasia tube 1 with get inspection cutter 2 and constitute, the afterbody of proctectasia tube 1 is provided with tubaeform empennage 3, gets inspection cutter 2 and is made of cutter head 4, knife bar 5 and handle of a knife 6, the side of cutter head 4 is provided with blade 7, and the top of cutter head 4 is provided with barb 8.
When using this utility model, earlier proctectasia tube 1 is inserted patient's rectum, fully expose lump, to get the cutter head 4 of examining cutter 2 along empennage 3 then thrusts in the lump, grasp handle of a knife 6 with blade 7 in one week of target location rotary-cut, reuse barb 8 catches on piece of tissue per rectum expansion tube 1 and takes out, and then the piece of tissue of taking out is put in the Specimen bottle that formalin fixed liquid is housed, and delivers to Pathology Deparment's laboratory examination and gets final product.
