Embodiment 1

[0033] Embodiment 1, the present invention is a new type of adjustable experimental cartilage planer, comprising a knife bar 11 and a knife holder 2 arranged on the knife bar 11, characterized in that, refer to figure 1 , the knife rest 2 is U-shaped and one end without opening is connected to the knife bar 11, and the open end of the knife rest 2 is fixedly connected with an upper splint 6, and the upper splint 6 is provided with a The lower splint 7, between the lower splint 7 and the upper splint 6 are provided with a number of blades 4 evenly distributed along the upper splint 6, wherein the upper splint 6 provides a fixed basis for the blade 4 groups, specifically, it can be on the upper splint 6. Set up a chute towards the side of the lower splint 7, so that the blade 4 is slidably connected in the chute. The lower splint 7 is used to provide a limit for the flipping of the blade 4, preventing the blade 4 from driving the upper splint 6 to turn over when it is stressed, a...

Embodiment 2

[0040] Embodiment 2, on the basis of Embodiment 1, the upper splint 6 and the lower splint 7 are 18-20 stainless steel metal sheets with different thicknesses, that is, stainless steel supported by +18% chromium + 10% nickel, which is more durable and more durable. Corrosion resistance and no metal ion precipitation at all, more suitable for medical environment, the same material has good elastic deformation ability, when the slider 8 moves to both sides, it can quickly return to the original state, the thickness of the upper splint 6 Greater than the thickness of the lower clamping plate 7, this setting can make the deformability of the upper clamping plate 6 smaller than that of the lower clamping plate 7, so that the distance between the upper clamping plate 6 and the lower clamping plate 7 can be kept consistent, and the 4 groups of blades can realize different bending arcs.

Embodiment 3

[0041] Embodiment 3, on the basis of Embodiment 1, the adjustment mechanism includes an upper adjustment bolt 5 passing through the knife holder 2;

[0042] Both sides of the open end of the knife rest 2 are provided with threaded holes for the knife rest 2, and the two upper adjusting bolts 5 are respectively placed in the corresponding threaded holes of the knife rest 2 and threaded, and one end of the two upper adjusting bolts 5 is respectively connected to the corresponding The sliding block 8 is contacted and connected. In this embodiment, the user rotates the two upper adjusting bolts 5 respectively to slide against the sliding block 8 during specific use in this embodiment, so that the 4 groups of blades are pushed into arcs of different shapes, so as to Adapt to different specimens.

Abstract

The invention relates to a novel adjustable experimental cartilage planing tool. The problems that an existing scalpel is strenuous in sampling and cutting, an obtained specimen is low in purity, andexperimental specimens are wasted are effectively solved. According to the technical scheme for solving the problems, the novel adjustable experimental cartilage planing tool comprises a tool bar anda tool rest arranged on the tool bar, and is characterized in that the tool rest is in a U shape, the unopened end of the tool rest is connected with the tool bar, the opened end of the tool rest is fixedly connected with an upper clamping plate, a lower clamping plate connected with the tool rest is arranged by the side of the upper clamping plate, and a plurality of blades evenly distributed along the upper clamping plate are arranged between the lower clamping plate and the upper clamping plate; and sliding blocks slidably connected to the upper clamping plate are arranged on the position,close to the two ends of the tool rest, between the upper clamping plate and the lower clamping plate, adjusting mechanisms making contact with the sliding blocks are arranged at the two ends of the tool rest correspondingly, and the two adjusting mechanisms can push the corresponding sliding blocks to slide along the upper clamping plate. The novel adjustable experimental cartilage planing tool is concise in structure, the specimens with high purity can be taken down easily and conveniently, and practicality is high.

Description

technical field [0001] The invention relates to the technical field of sampling tools for medical experiments, in particular to a novel adjustable cartilage planer for experiments. Background technique [0002] The collection of cartilage is an important part of cartilage-related cell experiments. The source of cartilage is mainly surgical specimens, including femoral head specimens, tibial plateau specimens, distal femur specimens, ankle joint specimens, etc. At present, the main tool for cartilage collection is a scalpel, which has the following problems: [0003] 1. Cutting is laborious. Although the cartilage texture is soft, it is still closely integrated with the subchondral bone. At the same time, the scalpel cuts in a straight line, and most of the surgical specimens are irregular and mostly round, which makes the cutting process more difficult; [0004] 2. The purity of the obtained specimens is not high. The depth of the specimens obtained by the scalpel cannot be...
