Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a specimen sampler. Background Art

[0002] A specimen sampler is a tool used to collect samples of plants and animals. It usually consists of a handle, a clamping part, and a sampling head. The handle is designed to be easy to hold, so that the operator can hold and control the sampler. The clamping part is used to clamp and fix the sample. Its design can be changed according to the sampling requirements. For example, the clamping head can be pliers, clamps, or other shapes. The sampling head is the part that actually contacts and collects the sample. It usually has a specific shape and size to meet the sampling requirements of different types of samples.

[0003] The specific application of the specimen sampler is as follows: in the medical field, after removing the tumor, the doctor needs to cut and collect the tumor, and then obtain the tumor tissue sample in the patient's body for pathological examination. For example, the patent document with announcement number CN208942209U proposes a special tool for specimen collection, which can directly press the cutting handle by placing the removed tumor on the support plate according to the position to be collected, so that the sharp bottom edge of the sampling sleeve cuts the tumor and removes the sample. This device makes specimen collection convenient and quick, but its sampling sleeve cannot be disassembled and replaced, so that the sampling volume of a single sampler is fixed and cannot meet the collection needs of specimens of different sizes. It also makes the cleaning and maintenance of the sampling sleeve very inconvenient. Utility Model Content

[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] The utility model provides a specimen sampler, combined with the attached Figure 1 , 2 As shown, the specimen sampler consists of a first clamp arm 1 and a second clamp arm 2, the middle parts of the two clamp arms are connected by a hinge shaft 4, the first clamp arm 1 is equipped with a tray 12, and the second clamp arm 2 is equipped with a corresponding cutting part 22, and a detachable cutting sleeve 3 is installed on the cutting part 22; and the first clamp arm 1 includes a first clamp handle 11, which is located on the other side of the hinge shaft 4, and the second clamp arm 2 includes a second clamp handle 21 opposite to the first clamp handle 11. Such a design allows the first clamp handle 11 and the second clamp handle 21 to move relative to each other through the hinge shaft 4. Through the relative movement of the first clamp handle 11 and the second clamp handle 21, the operator can control the opening and closing and clamping action of the sampler. When the first clamp handle 11 and the second clamp handle 21 are close to each other, the cutting sleeve 3 can be closed to clamp the tissue to be sampled, and when the first clamp handle 11 and the second clamp handle 21 are separated, the cutting sleeve 3 will open to release the tissue to be sampled.

[0021] When using the specimen sampler, first place the tissue specimen to be tested on the tray 12 of the first clamp arm 1, then adjust the angle between the two clamp arms so that the cutting portion 22 is correctly aligned with the target specimen. The operator can control the movement and clamping force of the clamp arm through the handle or grip. When sampling is to be performed, the operator inserts the cutting sleeve 3 into the cutting portion 22 and ensures that it is firmly fixed. Then, through appropriate control, the cutting sleeve 3 cuts the target specimen with the support of the cutting portion 22. The design and edge shape of the cutting sleeve 3 help to ensure the accuracy of the cutting process and the integrity of the specimen. After the sampling is completed, the cutting sleeve 3 can be removed and the cut specimen can be taken out for further testing and analysis. The detachable design of the cutting sleeve 3 can facilitate the operator to clean and disinfect the instrument to ensure hygiene and reduce the risk of cross infection. At the same time, cutting sleeves 3 of different sizes can be replaced to meet the specimen collection needs.

[0022] Furthermore, if Figure 3 As shown, a connecting column 23 is provided on the cutting portion 22, and the cutting sleeve 3 is sleeved on the connecting column 23. This design can make the cutting sleeve 3 more convenient to fix on the cutting portion 22, providing a more reliable cutting effect, and the connecting column 23 can have an appropriate diameter and length. When installing the cutting sleeve 3, the operator can insert the sleeve into the connecting column 23 for tightening.

[0023] Furthermore, the connecting column 23 has an external thread, and the interior of the cutting sleeve 3 is provided with a corresponding internal thread, such as Figure 3 As shown, each type of cutting sleeve 3 is separately provided with a barrel for docking with the connecting column 23, and a standard internal thread is provided in the barrel to be installed on the connecting column 23 accordingly, so as to realize the installation of cutting sleeves 3 of different sizes. This design chooses to use a threaded connection method to realize the firm fixation of the cutting sleeve 3 and the connecting column 23. The operator can screw the cutting sleeve 3 into the connecting column 23 to create a tight connection between it and the connecting column 23. The threaded connection provides a reliable fastening force to ensure that the cutting sleeve 3 will not loosen or fall off during use. In addition, the threaded connection method also makes it relatively easy to replace the cutting sleeve 3. The operator only needs to rotate the cutting sleeve 3 to loosen its thread, and then replace it with another cutting sleeve 3 with the same specification and thread. This replaceable design makes it more convenient and flexible to adapt to the sampling of tumor specimens of different sizes or requirements.

[0024] In addition, the utility model also optimizes the design of the tray 12, and a sampling carrier plate 13 is provided on the surface of the tray 12. The sampling carrier plate 13 is opposite to the cutting sleeve 3 to withstand the shearing of the cutting sleeve 3. The sampling carrier plate 13 is made of stainless steel, which has certain strength and corrosion resistance and is suitable for sampling tumor specimens.

[0025] Two limit baffles 14 are also provided on the surface of the tray 12. The two limit baffles 14 are respectively located on both sides of the sampling support plate 13. There is a slide groove 15 on the limit baffle 14. The extension direction of the slide groove 15 is the same as the length direction of the limit baffle 14. A sliding baffle 16 is also installed on the tray 12. The two ends of the sliding baffle 16 are respectively slidably arranged in the two slide grooves 15. Through the use of the limit baffle 14 and / or the sliding baffle 16, it can be ensured that the removed tumor is placed on the tray 12 and is properly limited to ensure that the tumor does not shift during the cutting and collection process, thereby ensuring smooth cutting.

[0026] Furthermore, in order to provide a stable operating platform, a non-slip silicone pad 17 is also provided at the bottom of the tray 12. The non-slip silicone pad 17 has good anti-slip properties, which can ensure that the entire sampler remains stable during operation and reduce the risk of sliding or moving.

[0027] Therefore, the cutting sleeve 3 is set to be detachable in the utility model, which can facilitate the operator to clean and disinfect the instrument to ensure hygiene and reduce the risk of cross infection. At the same time, the cutting sleeve 3 of different sizes can be replaced to meet the specimen collection requirements. The specimen sampler can provide good stability, accuracy and control during the sampling process. At the same time, the use of stainless steel and non-slip silicone pads 17 can also improve the durability and safety of the sampler.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
