Description

Pathologic section slicer

Technical field

The utility model relates to medical treatment and nursing technique with the apparatus field, be specifically related to a kind of can the pathologic section slicer of two-sided section.

Background technology

Pathologic section slicer is mainly used in medical treatment and nursing technical field, for the ill when injected organism tissue sample taking from animal (comprising people) is thinly sliced, existing microtome mainly divides electronic and manual two large classes, and two class microtomes are all by controlling section clamping device and clamp with blade relative motion cutting the section that framework clamps to realize cutting into slices.Microtome knife mostly is disposable blade, and blade needs to change in time, and the installation operation requirements of knife rest and blade both can firm clamping blade, and replacement operation is simultaneously simple, can not increase unnecessary workload to medical worker.Chinese patent CN203432814U discloses a kind of microtome kinfe holder, has the blade saddle by the maximum insert design of width, and the magnetic holder bar of different size, and the replacing realizing different blade is installed, highly versatile.But the microtome kinfe holder of above-mentioned patent, blade is arranged in knife rest by the absorption of magnetic holder bar, and blade is beated in the space easily between blade bearing and hold(ing)-down clip, causes lifts, is stained with the phenomenons such as cutter, impact section outward appearance and attractive in appearance.For this reason, application number is 201420194743.2, name is called a kind ofly the pathologic section slicer of two-sided section can disclose a kind of pathologic section slicer, substantially, to satisfy the demand, but, its holder designs bad, sliced materials varies, it is bad that off size suitable material blessing is fixed, and easily rocks, cause the precision of slice thickness not reach requirement during section.

Utility model content

For overcoming the defect of above-mentioned microtome, the utility model provides a kind of clamper fixed effect good pathologic section slicer.

For achieving the above object, the utility model have employed following technical scheme:

A kind of pathologic section slicer, comprise support, casing, clamper, slicing mechanism, handle, gear train, described gear train comprises the guide rail be arranged in support, rail brackets, slide block and screw mandrel, handle connection for transmission mechanism, gear train connects clamper, clamper is arranged on outside casing, slicing mechanism is arranged on below clamper, also comprise pallet, be arranged on bottom support by slide rail, described slicing mechanism comprises blade and knife rest, described knife rest comprises blade bearing and hold(ing)-down clip, blade bearing has handle of a knife saddle, blade is arranged between blade bearing and hold(ing)-down clip, hold(ing)-down clip has cascaded surface, described blade comprises the blade of handle of a knife and handle of a knife both sides, handle of a knife and blade are structure as a whole, handle of a knife coordinates with cascaded surface, between handle of a knife saddle inboard and blade bearing, there is a space, this space forms the blade coordinated with blade and receives, it is characterized in that: described clamper comprises sleeve, be provided with the holding piece of two arcs in sleeve, the radian of holding piece protrudes all laterally, and each holding piece connects at least two hold-down nuts, and hold-down nut coordinates with bush whorl.

Described sleeve in hold-down nut place fixing lug boss, boss and hold-down nut threaded engagement.

Described handle of a knife side has fin, hold(ing)-down clip has the groove coordinated with fin.

Described casing arranges scale mark along handle periphery.

Also comprise and be arranged on four suckers bottom support or universal wheel.

Also comprise two LED and control circuit, be arranged on clamper both sides on casing.

The beneficial effects of the utility model are: relative to prior art, the clamper of machine is provided with holding piece 32 and hold-down nut 33, when the size dimension of model of cutting into slices is not suitable especially, can adjust, do not affect the blessing effect of clamper, the precision of slice thickness can be made higher, facilitate next step operation.

Embodiment

As Fig. 1-3, a kind of pathologic section slicer, comprises support 12, casing 13, clamper 14, slicing mechanism 15, handle 16, gear train, and described gear train comprises the guide rail, rail brackets, slide block and the silk that are arranged in support 12

Bar etc., handle 16 connection for transmission mechanism, gear train connects clamper 14, clamper 14 is arranged on outside casing 13, slicing mechanism 15 is arranged on below clamper 14, also comprise pallet 17, be arranged on bottom support 12 by slide rail, described slicing mechanism 15 comprises blade 1 and knife rest 2, described knife rest 2 comprises blade bearing 3 and hold(ing)-down clip 4, blade bearing 3 has handle of a knife saddle 6, blade 1 is arranged between blade bearing 3 and hold(ing)-down clip 4, hold(ing)-down clip 4 has cascaded surface 5, described blade 1 comprises the blade 7 of handle of a knife 8 and handle of a knife 8 both sides, handle of a knife 8 and blade 7 are structure as a whole, handle of a knife 8 coordinates with cascaded surface 8, between handle of a knife saddle 6 inboard and blade bearing 3, there is a space, this space forms the blade coordinated with blade 7 and receives 9.

As Fig. 3, clamper 14 comprises sleeve 31, and be provided with the holding piece 32 of two arcs in sleeve, the radian of holding piece 32 protrudes all laterally, and each holding piece 32 connects at least two hold-down nuts 33, hold-down nut 33 and sleeve 31 threaded engagement.Better in order to what make hold-down nut 33 and sleeve 31 fix, sleeve 31 is at hold-down nut 33 place fixing lug boss (not drawing in boss figure), boss and hold-down nut 33 threaded engagement, relative to adding the contact area of sleeve 31 with hold-down nut 33, safer.During use, sliced materials is placed between two holding pieces 32, tightens hold-down nut 33, press nip sheet, section is firmly clamped by two holding pieces, convenient working.

Blade 1 has two blades 7, and two sides all can use.

Handle of a knife 8 is set in order to be arranged on blade bearing 3, handle of a knife 8 coordinates with handle of a knife saddle 6,6 carrying blades 1, more only need take out blade 1 during allowing blade replacement 1 oppositely puts on handle of a knife 8 saddle, tool changing operation is simple, easy to use, and during cutting blade can not slide easily, play, improve cutting knife, round and smooth impulse-free robustness.

Arrange blade storage 9 inside handle of a knife saddle 6, in order to hold blade 7, ensure blade 1 and the firm cooperation of blade bearing 3 on the other hand, during cutting, blade 1 can not be beated, and avoids lifts, is stained with cutter phenomenon, improve kerf quality.

Perfect as to such scheme, handle of a knife 8 arranges fin 10, hold(ing)-down clip 4 is arranged at the groove 11 that fin 10 coordinates, locked blade 1 and knife rest 2, make blade 1 and knife rest 2 reliable contacts, not easily produce bob, improve lifts, be stained with cutter phenomenon, improve kerf quality.

Further, of the present utility model can the pathologic section slicer of two-sided section, pallet 17 is set, places sampling material and other testing tools, easy to use.Meanwhile, on described casing 13, scale mark can be set along handle 16 periphery, described casing 13 arranges scale mark along handle 16 periphery, corresponding slice thickness swinging handle 16 to corresponding scale value, visual control slice thickness, easy to operate, precise control.

Decision design also comprises four universal wheels 18 be arranged on bottom support 12, and machine moves, turn to convenience.But, sometimes need to fix this machine, such as during hand fixed handle, cause can not accurately arriving corresponding scale value, so, also universal wheel 18 can be not installed, direct installation four suckers (not drawing in figure), during use, it is first-class that a dish is directly adsorbed on desk, and convenient handle accurately arrives corresponding scale value.

Also comprise two LED 19 and control circuit, be arranged on clamper 14 both sides on casing 13, in dark, place provides illumination, easy to use.
