Description
Technical field
This utility model belongs to pathologic sampling utensil in the medical apparatus and instruments of medical domain, the pathologic sampling cutter of particularly a kind of available clinical pathology specimen, obduction specimen and laboratory animal specimen sampling.
Background technology
Clinical pathology specimen, obduction specimen and laboratory animal specimen sampling are daily curative activities, the important component part of pathology work and life science worker routine work particularly, histopathology the draw materials quality of quality direct relation tissue slice of specimen even last pathological diagnosis, therefore, pathologic sampling is a ring important in clinical pathology, obduction and the zoopery work, and ideal pathologic sampling utensil then is the important prerequisite that guarantees this work.Positive so-called " worker's desire becomes its thing, must first sharpen his tools ".And one of apparatus the most commonly used is exactly that pathology is bent the material cutter in the pathologic sampling process, in the pathologic sampling process, often need utilize various pathologic sampling cutters that various specimen are managed the cutter of drawing materials, in the pathologic sampling process, often need utilize various pathologic sampling cutters to various specimen keep at a certain distance away (0.5～2cm spacing) cut open, to the tangent plane scrutiny, the position of determine to need checking at last, and tissue is cut into the small tissue blocks of consistency of thickness, and (the general piece of tissue thickness that requires to cut is 0.3cm ± 0.1cm).But, pathologic sampling cutter commonly used now mostly is long-term reusable cutter, that have even adopt amateur cutter to carry out pathologic sampling work, edges dull even curling phenomenon often appear after above-mentioned cutter repeatedly uses, need to whet a knife repeatedly, even the cutter that more renews, therefore use is inconvenient, cost is higher, and influences pathologic sampling efficient and the quality of drawing materials.Certainly also there is the staff to carry out pathologic sampling, but, is not suitable for drawing materials of specimen because surgical knife is too short with surgical knife.
In addition, be 0.3cm ± 0.1cm piece of tissue because the normal requirement of pathologic sampling cuts thickness, and pathologic sampling cutter commonly used mostly is hilted broadsword, operation inconvenience.We once disclosed a kind of " double pathologic sampling cutter " (patent No. ZL952191989) in the patent of nineteen ninety-five application and acquisition, though this patent has proposed the mentality of designing of double pathologic sampling cutter first, and in drawing materials, various cyst wall tissues play a significant role, but, because it adopts the structure of knife blade, therefore when big specimen sampling, usually the phenomenon that causes two Zhang Pings row blade front end to separate inadequately owing to blade strength influences the use of double pathologic sampling cutter in big specimen sampling process.
As seen, having the pathologic sampling cutter now all can not finish the incision of various Pathologic specimens smoothly, fast, draw materials, particularly (the general piece of tissue thickness that requires to cut is 0.3cm ± 0.1cm), reach the purpose that improves pathologic sampling quality and efficient to the requirement of piece of tissue thickness in the pathologic sampling work.Therefore, research and development are satisfied actual pathologic sampling requirements of one's work and novel pathologic sampling cutter with low cost has important economic benefit and social benefit.
Summary of the invention
The purpose of this utility model is the defective or the deficiency that exist at above-mentioned prior art, provides a kind of with low cost, easy to use and can improve the pathologic sampling cutter of pathologic sampling quality and efficient.
For achieving the above object, the technical solution used in the present invention is: comprise handle of a knife, be provided with the blade holddown groove that strengthens blade strength at the front end of handle of a knife, blade is arranged in the blade holddown groove and with handle of a knife fixedlys connected.
Blade holddown groove of the present utility model is one or two identical cell body that be arranged in parallel, and blade is flute length 4.0～20cm fixedly, dark 0.3～0.5cm, wide 0.5～1.5mm;
Blade is one or two identical disposable blade that be arranged in parallel, and the size of blade and blade holddown groove are complementary, and length is 4.0～20cm, wide 1.5～3.0cm, thick 0.5～1.5mm;
The spacing of two parallel blade holddown grooves is 0.2～0.5cm;
The blade holddown groove is connected as a single entity by welding, bolting, casting or forging and pressing mode and handle of a knife;
Offer the handle of a knife fixing hole on the handle of a knife, the rear end of blade offers the blade fixing hole that is complementary with the handle of a knife fixing hole, and blade is fixedlyed connected by bolt-nut with handle of a knife;
Blade is provided with draw-in groove, and handle of a knife is provided with the deck that adapts with draw-in groove, and blade is fixedlyed connected with deck by draw-in groove with handle of a knife.
This utility model promptly can be assembled into single pathologic sampling cutter or double pathologic sampling cutter according to handle of a knife and one or two disposable blade that the real work needs will have a blade holddown groove or two blade holddown grooves respectively according to the connected mode that is complementary, both solved the common pathology edges dull in the cutter life-time service of drawing materials, the problem of curling and need repeat to whet a knife, increased the intensity of original double cutter of drawing materials again, help Pathologic specimen cut open and (the general piece of tissue thickness that requires to cut is 0.3cm ± 0.1cm) to the requirement of the piece of tissue thickness of drawing materials, reach and improve pathologic sampling quality and efficient, satisfy the pathologic sampling job demand.
