Abstract
The utility model relates to the technical field of fish pituitary sampling, and discloses a fish pituitary sampling tool which comprises a first crank arm and a second crank arm, wherein the first crank arm and the second crank arm are symmetrically arranged, one ends of the first crank arm and the second crank arm are fixedly connected, the other ends of the first crank arm and the second crank arm are separated to form an opening, the non-connecting ends of the first crank arm and the second crank arm are respectively provided with a spoon body, the spoon bodies are mutually combined to form a pituitary accommodating cavity, and the spoon body is provided with a cutter for cutting a tissue connected with a pituitary. Through mutually supporting of first crank arm and second crank arm, can be used for holding the cavity of pituitary to the synthesis with the spoon body that sets up at crank arm end, guarantee that the pituitary does not receive the damage of other external forces at the sampling in-process, promoted the stability of sampling, set up circular small opening on the spoon body simultaneously, be favorable to the discharge of unnecessary tissue liquid, through setting up the cutter on the spoon body, make the spoon body excise the pituitary when closing, simplify the sampling process of pituitary.
Description
Technical Field
The utility model relates to the technical field of fish pituitary sampling, in particular to a fish pituitary sampling tool.
Background
In the sampling process of fish pituitary, because operating personnel's proficiency is different, the condition that the pituitary tissue that often can appear because of the operation is cut the shake and is caused cuts improperly for the pituitary suffers the damage, and after cutting the pituitary, often because of the power size that the pituitary was got to the clamp of using tweezers is improper, leads to the cracked condition of pituitary, and the experimental cost of increase is unfavorable for user's use.
Therefore, we propose a fish pituitary sampling tool to solve the above problems.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a fish pituitary sampling tool to solve the problems in the background technology.
In order to achieve the purpose, the utility model provides the following technical scheme:
the utility model provides a fish pituitary sampling instrument, includes that first crank arm and second crank arm, first crank arm and second crank arm symmetry set up and one end fixed connection, and the other end separation forms the opening, the non-link of first crank arm and second crank arm all is equipped with the spoon body, the spoon body is closed each other and is formed pituitary and hold the cavity, be equipped with the cutter on the spoon body for separate the pituitary.
As a still further scheme of the utility model: the spoon body is provided with a circular leak hole.
As a still further scheme of the utility model: the boundary surface of the spoon body is flush with the cutting edge of the cutter.
As a still further scheme of the utility model: an opening adjusting rod is arranged between the first crank arm and the second crank arm and is in threaded fit with the screw cap, and the opening adjusting rod is used for adjusting the distance between the first crank arm and the second crank arm.
Compared with the prior art, the utility model has the beneficial effects that:
1. through mutually supporting of first crank arm and second crank arm, can be used for holding the cavity of pituitary to the synthesis with the spoon body that sets up at crank arm end, guarantee that the pituitary does not receive the damage of other external forces at the sampling in-process, promoted the stability of sampling, set up circular small opening on the spoon body simultaneously, be favorable to the discharge of unnecessary tissue liquid, through setting up the cutter on the spoon body, make the spoon body excise the pituitary when closing, simplify the sampling process of pituitary.
2. Through setting up the aperture regulation pole for the opening distance between first crank arm and the second crank arm can be controlled, when to the different fish pituitary of sampling, sets up different apertures, prevents to make equipment oppress the peripheral tissue of pituitary because of the elasticity between the crank arm, reduces the destruction of sampling instrument to the peripheral tissue of pituitary.

Detailed Description
Referring to fig. 1 to 4, in the embodiment of the utility model, a fish pituitary sampling tool comprises a first crank arm 1 and a second crank arm 2, wherein the first crank arm 1 and the second crank arm 2 are symmetrically arranged, one end of each first crank arm 1 is fixedly connected with the other end of each second crank arm 2, the other ends of the first crank arm 1 and the second crank arm 2 are separated to form an opening, spoon bodies 3 are arranged at the non-connecting ends of the first crank arm 1 and the second crank arm 2, the spoon bodies 3 are mutually combined to form a pituitary accommodating cavity, a circular leak hole 31 is formed in each spoon body 3, and redundant tissue fluid in the cavity of the spoon body 3 is discharged through the circular leak hole 31, so that pituitary injury is reduced;
the spoon body 3 is provided with a cutting knife 4 for cutting a tissue connected with a pituitary, a boundary surface of the spoon body 3 is flush with a cutting edge of the cutting knife 4, the pituitary is clamped through a boundary plane of the spoon body 3 and moves to the inside of a cavity of the spoon body 3, the cutting knife 4 cuts the tissue connected with the pituitary during the involution process of the spoon body 3, the separation of the pituitary is ensured, an opening adjusting rod 5 is arranged between the first crank arm 1 and the second crank arm 2, the opening adjusting rod 5 is in threaded fit with the screw cap 51 and is used for adjusting the distance between the first crank arm 1 and the second crank arm 2, and the size of an opening of the device is controlled by adjusting the distance between the crank arms, so that the compression on the tissue around the pituitary during the process of releasing the elasticity of the device is reduced, and the damage on the surrounding tissue is reduced.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and equivalent alternatives or modifications according to the technical solution of the present invention and the inventive concept thereof should be covered by the scope of the present invention.
