Description

Multi-level thickness positioning cutter

technical field

The invention relates to an anatomical instrument, in particular to a knife for multi-level thickness positioning and cutting of cephalopod gonad tissue.

Background technique

When analyzing cephalopod gonad tissue slices, the thickness of the tissue block will affect the subsequent experiments to a certain extent: if the thickness of the tissue block is too thick, it will increase the time cost during dehydration; if the tissue block is too thick , it affects the cutting of the sample when slicing, and also brings certain difficulties in embedding.

Adopting the scalpel of the prior art may cut and form tissue samples with inconsistent thickness, causing the above-mentioned problems in subsequent processing.

Contents of the invention

The technical problem to be solved by the present invention is to provide a multi-level thickness positioning cutter capable of cutting tissue material with uniform thickness.

In order to solve the above-mentioned technical problems, the multi-stage thickness positioning cutter provided by the present invention includes a knife handle and a fixed blade fixed at one end of the knife handle. The blade is arranged at the end of the bottom surface of the knife handle; adjacent to the fixed blade is also provided with a sliding blade holding bead groove, and a sliding knife holder can be pulled and moved to a set position in the described holding bead groove, so that The sliding blade and the fixed blade are positioned parallel to each other in multiple stages of spacing.

According to a further technical solution of the present invention, the sliding tool holder includes a sliding blade, the two ends of the sliding blade are provided with locking beads, which can be positioned in the locking bead groove, and the two ends of the sliding blade are respectively connected with a shrapnel.

The shrapnel at both ends of the sliding blade can not only be used as a handle to pull the sliding blade, but also play an auxiliary role in fixing the sliding blade in the bead groove of the sliding blade. When in use, by pulling the shrapnel at both ends of the sliding blade, the ball of the sliding blade is moved out of a group of slots, and slides to the adjacent slot in the direction of force, and the ball of the sliding blade enters the corresponding slot of the group. Fixed in the card slot.

In a further technical solution of the present invention, the sliding blade clamping bead groove is provided with at least one set of locking grooves.

In a further technical solution of the present invention, the sliding blade clamping bead groove is provided with three sets of locking grooves.

In a further technical solution of the present invention, the fixed blade and the sliding blade are respectively parallel to the direction of the handle.

In a further technical solution of the present invention, the fixed blade is installed in a fixed blade holder, and a spring clip is arranged in the fixed blade holder to clamp the fixed blade.

Beneficial effects of the present invention: 1. The multi-stage thickness positioning cutter of the present invention can realize uniform thickness and standardized tissue block cutting;

2. The multi-stage thickness-positioning cutter of the present invention can quickly cut the required tissue block samples, reduce the cost of experiment time, and minimize the cost of consumables.

Detailed ways

In order to make the technical means, creative features, goals and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

The cutter device 1 of multi-stage thickness positioning cutting as shown in Figure 1-2, comprises the handle of a knife 10 of flat strip shape, and the fixed blade 2 that is established at one end of the bottom surface of handle 10, at the end of handle of a knife, adjacent to this fixed blade The blade 2 is also provided with a sliding blade holding bead groove 3, and a sliding knife holder can be pulled and moved to a set position in the sliding blade holding bead groove 3, so that the sliding blade 4 and the fixed blade 2 form a parallel Multi-stage pitch positioning, and preferably the fixed blade 2 and the sliding blade 4 are parallel to the direction of the knife handle 10; , and the two ends of the sliding blade are respectively connected with a shrapnel 42 . When it is necessary to adjust the thickness of the slice, by pulling the elastic pieces 42 at both ends of the sliding blade, the bead 41 of the sliding blade 4 is moved out of a group of locking grooves 31, and slides to the adjacent locking groove 31 in the direction of force, and the locking of the sliding blade 4 The beads 41 also correspondingly enter the set of locking grooves 31 to be fixed.

The sliding blade clamping bead groove 3 is provided with at least one set of clamping grooves 31. In the embodiment of FIG. , such as h1 (0.2cm), h2 (0.3cm), h3 (0.5cm).

In a preferred embodiment of the present invention, the fixed blade 2 is installed in the fixed blade holder, and the fixed blade holder is provided with a spring clip 21 to clamp the fixed blade.

The fixed blade or/and sliding blade in the present invention can use the common surgical blade (carbon steel) that sells on the market. The knife device in the present invention is particularly suitable for multi-level thickness positioning and cutting of cephalopod gonadal tissue. Of course, other tissue cutting applications that those skilled in the art can think of can also be used, which all belong to the application scope of the knife device of the present invention.

The basic principles, main features and advantages of the present invention have been shown and described above. Those skilled in the art should understand that the present invention is not limited by the above-mentioned embodiments, and that described in the above-mentioned embodiments and the description only illustrates the principles of the present invention, and the present invention also has various aspects without departing from the spirit and scope of the present invention.
