Abstract

The utility model discloses a changeable double head material taking knife, which relates to the technical field of medical operation specimen material taking knife. The changeable double head material taking knife comprises a blade (1), a cutter clamp (2) and a cutter handle (3), which is characterized in that two cutter clamps (2) are arranged on one end of the cutter handle (3), two cutter clamps (2) are respectively provided with a changeable blade (1), the blade (1) inside the two cutter clamps (2) are mutually paralleled, the cutter edges of the blade (1) inside the cutter clamp (2) are synclastic, and the end of the two blades (1), which not inserts into the cutter clamp (2) are mutually aligned; the blade (1) adopts a disposable cutter blade wasted by the histotome. Because of the changeable double head material taking knife of the utility model adopts the structure of double-pole parallel so that the changeable double head material taking knife can save time and save labor when the utility model takes material, and convenient operation, and the changeable double head material taking knife can observe the four faces of the gross specimen by cutting once, and the integrity of the material can be improved to improve the quality of the slicing.

Description

The interchangeable double end cutter of drawing materials

Technical field

This utility model relates to a kind of medical apparatus and instruments, particularly a kind of medical operating cutter of drawing materials.

Background technology

Traditional hospital pathology department medical operating draw materials the cutter tool all usefulness be the single blade cutter of drawing materials, partial application can only be observed two faces of specimen substantially.When cutting the more internal organs of layering, as: tissues such as coat of the stomach, intestinal wall, gallbladder wall, eyeball, easily cause the uneven or separation of level, especially in the quick freezing section, fresh tumor specimen is without formaldehyde fixed, and is soft, tumor tension force is higher, single solution for diverse problems is gone down, and tumor peplos is just translated on one side, cut comparatively difficulty of total incapsulation.Yet in the pathological diagnosis of thyroid tumor, whether peplos is complete good pernicious particularly important to judging thyroid tumor.

The utility model content

The purpose of this utility model is that design in order to address the above problem a kind of can make things convenient in medical operating, saves time, laborsaving interchangeable double end of intactly dissecting is drawn materials cutter.

In order to achieve the above object, the interchangeable double end provided by the utility model cutter of drawing materials, it comprises:

Blade, cutter holder and handle of a knife, an end of handle of a knife is provided with two cutter holders, respectively is provided with the blade that a slice can plug in two cutter holders, and the blade in two cutter holders is parallel to each other, and the edge of a knife of blade is in the same way in the cutter holder; Two blades do not insert the end alignment of cutter holder; Blade adopts histotome with blunt depleted disposable blade.

The interchangeable double end of this utility model design cutter of drawing materials owing to adopted the parallel structure of double-pole, so dissect, can save time when drawing materials, laborsaving, easy to operate, partial application just can be observed four faces of specimen substantially, and can improve the integrity of drawing materials, thereby improves the quality of section; The specimens from pri that this cutter of drawing materials can be widely used in hospital pathology department is drawn materials, the specimen sampling of the histology of medical colleges and schools, pathology teaching section, the specimen sampling of public security bureau's medicolegal autopsy, the relevant human body of zoological specimens and scientific research institutions of herding veterinary's specialty or the specimen sampling of animal histology hold in agriculture university; Since the blade that uses be histotome with blunt depleted disposable blade, so can save cost, shortened the time of drawing materials simultaneously.
