Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of fish muscle collection devices, and in particular to a rapid collection device for muscle tissue samples. Background Technology
[0002] The collection of fish muscle tissue samples is of great significance in aquaculture, fish resource surveys, molecular biology research, and nutritional analysis. Muscle is the main carrier of fish protein. In some scientific research experiments and studies, it is necessary to collect fish muscle samples for related molecular biology experiments and analysis of the nutritional components in fish. The nutritional components of muscle are an important standard for evaluating fish quality.
[0003] In experiments, the fish samples taken are often small in size due to the variety and experimental requirements. Traditional sampling methods, such as incision sampling, are difficult to operate. Using scissors or a knife to sample the fish meat is not suitable for small samples, which makes the operation quite difficult. Moreover, when cutting and sampling, the muscle tissue collected is easily lost due to the small sample size, which is both time-consuming and labor-intensive. Therefore, a rapid muscle tissue sampling device is needed to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to solve the problems mentioned in the background section.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A rapid collection device for muscle tissue samples includes a sample storage tube with a handle on the right side. The handle includes a shank, and a tweezers section is located on the left side of the shank. The shank is fastened to the right side of the sample storage tube. A threaded shaft is threaded into the right side of the shank and fixed to the left and right sides of a docking seat. One end face of the threaded shaft is connected to a cutting part, which includes a blade threaded into the end face of the threaded shaft. A threaded insert is threaded to the end of the blade away from the threaded shaft, and two crescent-shaped hook blades are symmetrically connected to the left and right sides of the threaded insert. A spike is connected to the right side of the threaded insert, and several hook teeth are evenly arranged on the outer side of the spike tip. The hook teeth on the surface of the spike can hook into the inside of the muscle tissue sample to ensure stability when handling the muscle tissue sample.
[0007] Preferably, the crescent hook blade has a pointed hook structure at its end, and both the inner and outer sides of the crescent hook blade are sharp edges. The pointed hook structure of the crescent hook blade can be inserted into the fish muscle tissue sample and pulled and cut through the inner sharp edge. The inner and outer sides work together during cutting to ensure the cutting rate of small muscle tissue samples.
[0008] Preferably, the right side of the mating seat is covered with a cap, and the surface of the cap has a curved concave structure. The cap can be fastened to the outward-facing threaded shaft surface to wrap the threaded shaft, prevent wear of the external threads, and avoid affecting the subsequent mating of the threaded shaft with the shank.
[0009] Preferably, the tweezers part includes a threaded insert shaft, which is inserted into the left end face of the handle through a threaded hole. A tweezer clip is connected to the left side of the threaded insert shaft. The end of the tweezer clip is bent, and the bending angle is between 25° and 45°. The bent structure design of the end of the tweezer clip can facilitate the clamping of fish muscle tissue samples. The flat and wide plane design of the bent part of the tweezer clip can expand the clamping effect of fish muscle tissue samples.
[0010] Preferably, the inner clamping rod end of the tweezers is movably mounted with a movable shaft through a through hole, and a support spring is sleeved on the surface of the movable shaft. The two ends of the support spring abut against the inner wall of the tweezers, and the elastic force of the support spring can support the inner wall of the tweezers under normal elasticity, so that the tweezers can be in an expanded state under normal conditions.
[0011] Preferably, the movable shaft is provided with disc ends on both ends, and the outer diameter of the disc ends is larger than the inner diameter of the tweezers through hole. The inner side of the tweezers tip is provided with several anti-slip blocks, and the vertical cross section of the anti-slip blocks is designed with a concave structure. When the tweezers are pressed on both sides to hold the fish muscle tissue sample, the anti-slip blocks can be fastened to the inside of the fish muscle tissue to form a certain degree of hooking effect and ensure the stability during clamping.
[0012] This utility model has at least the following beneficial effects:
[0013] By incorporating a cutting section, this device enables portable cutting of fish muscle tissue samples. Compared to traditional structures, this device features a detachable cutting section, particularly a crescent-shaped hook with a pointed end and sharp edges on both the inner and outer sides. This allows for easy insertion into the fish muscle tissue, utilizing the inner sharp edge of the crescent hook for pulling and cutting, combined with the outer curved sharp edge for direct cutting. This significantly improves the cutting efficiency and success rate for small, easily slippery muscle tissue samples, effectively preventing sample loss during the cutting process.
[0014] By adopting a modular design, the tweezers part is connected to the handle's shank via a threaded insert shaft, and the cutting part is connected to the blade bar via a threaded insert rod, which in turn mates with the threaded shaft of the docking seat. This design allows key working components such as the tweezers clamp and crescent hook blade to be disassembled and replaced independently and conveniently. Users can quickly change the appropriate clamping or cutting components according to different collection needs. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0023] Reference Figures 1-5A rapid collection device for muscle tissue samples includes a sample storage tube 1, a handle 2 on the right side of the sample storage tube 1, the handle 2 including a handle tube 21, a tweezers part 3 on the left side of the handle tube 21, the handle tube 21 being fastened to the right side of the sample storage tube 1, a threaded shaft 23 being threadedly inserted into the right side of the handle tube 21, and the threaded shaft 23 being fixed to the left and right sides of the docking seat 22, a cutting part 4 being provided at one end of the threaded shaft 23, the cutting part 4 including a knife bar 41 threadedly inserted into the end face of the threaded shaft 23, a threaded insertion rod 42 being threadedly connected to the end of the knife bar 41 away from the threaded shaft 23, and two crescent hook blades 43 being symmetrically connected to the left and right sides of the threaded insertion rod 42.
[0024] The end of the crescent hook blade 43 has a pointed hook structure, and both the inner and outer sides of the crescent hook blade 43 are sharp edges.
[0025] The right side of the threaded insert 42 is connected to a spike 44, and the outer side of the spike 44 is provided with several hook teeth evenly arranged.
[0026] The right side of the docking seat 22 is covered with a cap 24, and the surface of the cap 24 has a curved concave structure.
[0027] The tweezers part 3 includes a threaded insert shaft 31, which is inserted into the left end face of the handle 21 through a threaded hole. A tweezers clip 32 is connected to the left side of the threaded insert shaft 31. The end of the tweezers clip 32 is bent, and the bending angle is between 25° and 45°.
[0028] A movable shaft 33 is movably mounted on the inner clamping rod end of the tweezers 32 through a through hole, and a support spring 34 is sleeved on the surface of the movable shaft 33, with both ends of the support spring 34 abutting against the inner wall of the tweezers 32.
[0029] The movable shaft 33 has disc ends on both sides, and the outer diameter of the disc ends is larger than the inner diameter of the through hole of the tweezers 32. Several anti-slip blocks 35 are provided on the inner side of the tip of the tweezers 32, and the vertical cross section of the anti-slip blocks 35 is designed with a concave shape.
[0030] The curved outer side design of the crescent hook blade 43 facilitates direct cutting. The pointed hook structure of the crescent hook blade 43 can be inserted into the fish muscle tissue sample and pulled and cut through the inner sharp edge. The inner and outer sides work together to ensure the cutting rate of small muscle tissue samples. When the spike 44 is inserted into the muscle tissue sample, the hook teeth on the surface of the spike 44 can hook back into the muscle tissue sample to ensure the stability when picking up the muscle tissue sample.
[0031] After the tweezers part 3 is inserted into the sample storage tube 1, the cutting part 4 is placed inside the handle tube 21. The cap 24 can be flipped onto the outward-facing threaded shaft 23 surface to cover the threaded shaft 23, preventing wear on the external threads and affecting the subsequent docking of the threaded shaft 23 with the handle tube 21, while also improving the overall aesthetics. The curved concave surface design of the cap 24 makes it easy to install and remove the cap 24. The bent structure design at the end of the tweezers 32 makes it easy to hold fish muscle tissue samples. The flat and wide tweezers 32 with a flat design at the bend can expand the holding effect of fish muscle tissue samples. The threaded connection between the threaded shaft 31 and the handle tube 21 makes it easy to replace the tweezers 32. The modular disassembly and assembly design makes it easy to perform independent sterilization.
[0032] A support spring 34 is sleeved on the surface of the movable shaft 33. The elastic force of the support spring 34 can support the inner wall of the tweezers 32 under normal elasticity, so that the tweezers 32 can be in an expanded state under normal conditions, which is convenient for holding small fish samples. When the tweezers 32 are pressed on both sides to hold fish muscle tissue samples, the anti-slip block 35 can be fastened to the inside of the fish muscle tissue to form a certain degree of hooking effect, ensuring the stability during holding and preventing the fish muscle tissue from being dropped during holding. The disc end design on both sides of the movable shaft 33 can prevent the two rod ends of the tweezers 32 from being over-expanded. The length of the movable shaft 33 is adapted to control the unfolding angle of the tweezers 32.
[0033] Working principle: According to Figure 2 and Figure 3 As shown, during use, the handle 21 is pulled out from the right side of the sample storage tube 1. At the same time, the docking seat 22 is rotated to separate the threaded shaft 23 from the right side of the handle 21. At this time, the docking seat 22 is flipped left and right, so that the cutting part 4 is pulled out of the handle 21 and placed to the right. Then, the threaded shaft 23 is re-connected to the right side of the handle 21. According to the requirements of the usage environment, the combination style of the crescent hook blade 43 and the threaded insert 42 can be freely changed by threading the threaded insert 42 to the right side of the knife bar 41. Here, the crescent hook blade 43 is shown as an opposing crescent shape. When the assembly is completed, the surface of the fish is cut through the cutting edge of the crescent hook blade 43, so that the hook end of the crescent hook blade 43 is inserted into the cut surface of the fish body, and the cutting is completed quickly by pulling out the hook end of the crescent hook blade 43. When removing the fish muscle tissue, two situations will occur:
[0034] In the first scenario, when the hook tip of the crescent hook blade 43 is inserted into the cut surface of the fish body in conjunction with the spike 44, the spike 44 breaks open the fish flesh inside the cut. When the crescent hook blade 43 is pulled outward, the inner side of the hook blade 43 and the tip engage to hook and pull out some fish muscle tissue. At this time, the tweezers 32 are held and rotated to separate the threaded insert shaft 31 from the left side of the handle 21, making it easier to grasp and remove the fish flesh tissue hooked on the inner side of the crescent hook blade 43 using the tweezers 32. The specific grasping method is as follows: Figure 3As shown, when the tweezers 32 are pressed, the anti-sliding blocks 35 on both sides of the tweezers 32 are pressed to pinch the muscle sample taken from the surface of the spike 44, thereby placing the muscle sample in the sample storage tube 1 for temporary storage. The muscle sample can be temporarily stored with the help of preservation media such as ice. The cap 24 can be temporarily covered on the right side of the sample storage tube 1 to seal it and prevent the sample storage tube 1 from tipping over and causing the sample to fall out.
[0035] In the second scenario, when the crescent-shaped hook blade 43 cuts the fish muscle sample to create a block-like structure, part of the fish muscle sample remains connected to the fish body. The spike 44 is inserted into the cut block-like fish muscle sample, and the hook teeth of the spike 44 create a certain degree of interlocking within the fish muscle sample to prevent it from falling out. As the spike 44 is withdrawn from the fish body incision, the fish muscle sample can be removed. Similarly, according to... Figure 3 As shown, the tweezers 32 is held and rotated to separate the threaded insert 31 from the left side of the handle 21. The tweezers 32 is pressed down, and the pressure on both sides of the tweezers 32 causes the anti-sliding slider 35 to pinch the muscle sample taken from the surface of the spike 44, thereby placing the muscle sample in the sample storage cylinder 1 for temporary storage. The muscle sample can be temporarily stored with the help of preservation media such as ice. The cap 24 can be temporarily covered on the right side of the sample storage cylinder 1 to seal it and prevent the sample storage cylinder 1 from tipping over and causing the sample to fall out.
