Problems solved by technology

[0002] At present, the preparation of soft tissue tensile test specimens generally uses casing cutters to prepare cylindrical specimens, but when taking a specific length, the specimen needs to be taken out and then cut to length, which is a waste of time and because the process of taking out Soft tissue deformation leading to inaccurate cropping
However, when the trocar knife is first in contact with the soft tissue, the tissue is deformed, so the size of the tip is larger than normal
For the standard sample, the middle part is generally selected for cutting, and its disadvantages: it cannot be formed at one time, which reduces the cutting accuracy and low efficiency

Embodiment 1

[0024] like Figure 1 to Figure 3 As shown, the present embodiment provides a soft tissue cylindrical sample cutting tool device, including a tubular knife 1, two telescopic knives are connected to the tubular knife 1, and the two telescopic knives are respectively arranged on both sides of the tubular knife 1 , the cutter heads of the two telescopic knives are arranged facing each other; when the soft tissue enters the tubular knife, the two telescopic knives work simultaneously into the tubular knife to cut the middle part of the soft tissue.

[0025] Wherein, the two telescopic knives include the upper telescopic knife 5 and the lower telescopic knife 7, the upper telescopic knife 5 and the lower telescopic knife 7 are identical in structural design, the upper telescopic knife 5 and the lower telescopic knife 7 are arranged on the axis of the tubular knife 1 On both sides, the upper telescopic knife 5 and the lower telescopic knife 7 are separated by a certain distance, and...

Embodiment 2

[0030] A soft tissue cylindrical sample cutting cutter device, the structure is as described in embodiment 1, the difference is that: the angle between the inclined plane and the plane is 10°.

Embodiment 3

[0032] A method for using a soft tissue cylindrical sample cutting tool device, using the cutting tool device described in Embodiment 1, the specific operation process is as follows:

[0033] Put the soft tissue to be tested into the tubular knife, and the two ends of the soft tissue protrude from the tubular knife 1. The user pushes the handles 4 of the two telescopic knives in the direction of the tubular knife 1 at the same time, and the telescopic knife moves toward the tubular knife. Knife 1 moves in the direction, and the cutter heads 8 of the two retractable cutters simultaneously cut off the soft tissue in the tube body of the tubular cutter 1, pull out the cut off soft tissues at both ends of the tubular cutter 1, and finally pull the retractable cutter outward, so that the cutter heads 8 leave Take the tube body of the tube knife 1, and then take out the soft tissue in the middle part cut off in the tube body of the tube knife 1 to obtain a soft tissue cylindrical sam...

Abstract

The invention relates to a soft tissue cylindrical sample cutting tool device and an application thereof. The device comprises a tubular knife, the tubular knife is connected with two telescopic knives, the two telescopic knives are respectively arranged at two sides of the tubular knife, and the tool bits of the two telescopic knives are arranged oppositely; and when a soft tissue enters the tubular knife, the two telescopic knives simultaneously enter the tubular knife, and cut off the middle part of the soft tissue. The cutting tool device realizes one-shot molding of a soft tissue sample, so the change of a cutting reference in the fetching and placing process is avoided, the cutting error caused by deformation of the soft tissue is reduced, and the efficiency of the whole experiment is improved. The cutting tool device has the advantages of ingenious structure design, simplicity in operation, low cost, realization of series production to meet requirements of soft tissue cylindrical samples having different lengths, obvious effect and excellent effect.

Description

technical field [0001] The invention relates to a soft tissue cylindrical sample cutting cutter device and an application thereof, belonging to the technical field of experimental equipment. Background technique [0002] At present, the preparation of soft tissue tensile test specimens generally uses casing cutters to prepare cylindrical specimens, but when taking a specific length, the specimen needs to be taken out and then cut to length, which is a waste of time and because the process of taking out Soft tissue deformation leads to inaccurate cropping. However, when the trocar knife is first in contact with the soft tissue, the tissue is deformed so that the size of the tip is larger than normal. For the standard sample, the middle part is generally selected for cutting. The disadvantage is that it cannot be formed at one time, which reduces the cutting accuracy and low efficiency. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the pre...
