Description

Technical Field

[0002] Animal disease monitoring is the basis for understanding the prevalence of animal diseases and pathogen mutations, and is crucial for animal prevention and control. At present, African swine fever, porcine reproductive and respiratory syndrome and other swine diseases severely threaten the healthy development of the pig industry. In the harmless treatment link, sampling and monitoring of organ tissues of dead pigs has the advantages of economy, high efficiency, and low biosafety risk. However, at present, sampling of organ tissues of frozen dead pigs can only be performed after the carcass is thawed, and conventional instruments can be used to perform external dissection and collection of internal tissues and organs in sequence. This method of sampling is very likely to cause biosafety hazards and environmental pollution due to blood stains. Therefore, sampling of internal organs of frozen dead pigs requires an instrument that can quickly cut the external skin without thawing to collect internal organ tissues. Utility Model Content

[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below in combination with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] Combined with the embodiments and Figure 1-5The organ tissue sampler for frozen dead pigs includes an electric drill 1, a first serrated disc 2 and a second serrated disc 3. The head of the electric drill 1 is fixedly connected with a drill seat, and a drill rod 11 connected to a motor is arranged on the drill seat. One of the first serrated disc 2 and the second serrated disc 3 is matched with the drill rod 11, and the outer diameter of the first serrated disc 2 is larger than the outer diameter of the second serrated disc 3; the center of the second serrated disc 2 is sleeved with a mounting sleeve 4, and one end of the mounting sleeve 4 is detachably connected to the drill rod 11 as a mounting end; the other end is concave to form a sample storage cavity 40 as a sampling end, and the opening of the sample storage cavity 40 is located on the front of the second serrated disc 3, and a sampling tongue 41 is connected to the sampling end. The electric drill 1 can be a pen-shaped or gun-handle-shaped electric drill. The outer edge of the sampling tongue is a sharp blade, which is convenient for cutting and collecting tissue samples.

[0018] Furthermore, the lower portion of the sampling tongue 41 extends along the length direction of the mounting sleeve 4 to form a sampling inclined surface 42 protruding from the front side of the second serrated disk 3, so that samples can be collected easily through the sampling inclined surface.

[0019] The outer diameter of the first serrated disk 2 is 10-15 cm, and the first serrated teeth 20 are provided on the outer periphery of the first serrated disk 2. The first serrated teeth 20 are located on the front side of the first serrated disk 2 and extend axially outward. The sawtooth depth of the first serrated teeth 20 is 2.5-3.5 cm, which is convenient for quickly cutting the external skin to form a circular exposed surface.

[0020] The outer diameter of the second serrated disk 3 is 1.5-2.5 cm, the length of the drill rod 11 is not less than 5 cm, and the edge of the second serrated disk 3 is provided with second serrations 30, which are located at the outer periphery of the second serrated disk 3 and extend radially outward.

[0021] A push piece 5 is slidably connected inside the mounting sleeve 4, and the outer periphery of the push piece 5 abuts against the inner wall of the sample storage chamber 40, and the push piece 5 is arranged obliquely to the axis of the mounting sleeve 4. A push handle 50 is connected to the push piece 5, and a sliding groove for exposing the push handle 50 is opened on the outer wall of the mounting sleeve 4, and the sliding groove is communicated with the sample storage chamber 40.

[0022] The sample storage cavity 40 has a circular cross section, and the slide groove includes a long groove 61 and a short groove 62 that are connected. The long groove 61 is arranged along the length direction of the mounting sleeve 4, and one end of the long groove 61 is connected to the sampling end, and the other end is connected to the short groove 62 arranged along the circumference of the mounting sleeve 4. The circumferential short groove is arranged to limit the sliding of the push handle, so as to avoid the phenomenon that the push piece pushes the sample out of the sample storage cavity during the sampling process.

[0023] Furthermore, a mounting hole is opened at the center of the second serrated disk 30 , an inner wall of the mounting hole is provided with an internal thread, and the mounting sleeve 4 is threadedly connected to the second serrated disk 30 .

[0024] Furthermore, when the push handle 5 abuts against the back of the second serrated disk 30, the push piece 5 is partially exposed on the sampling slope 42, which facilitates the sample transfer operation; or the angle between the push piece and the axis of the mounting sleeve is smaller than the angle between the sampling slope and the mounting sleeve.

[0025] When in use, first match the first serrated disk with the drill rod to perform external cutting operations on frozen dead pigs; after the internal tissue is exposed, switch the second serrated disk to match the drill rod to cut the lesions or sampled organ tissues. After the cutting is completed, confirm that the push handle is in the short slot, and collect the sample into the sample storage cavity through the sampling tongue. When transfer is required, move the push handle from the short slot to the long slot, slide the push piece along the length of the sample storage cavity, and push the sample into an external centrifuge tube or sample bottle for storage. During disinfection operations, the installation sleeve can be detached from the second serrated disk, and the push piece can be removed by pushing the push handle along the long slot to the sampling end. At this time, the push piece, installation sleeve, and second serrated disk can be disinfected separately.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
