Description

Technical Field

[0001] The present invention relates to the technical field of samplers, and specifically to a sampler. Background Art

[0002] Mammary tumors refer to tumors occurring in the mammary gland, which are divided into benign tumors and malignant tumors. They often manifest as breast masses. Breast masses are the most common symptom of breast cancer, and about 90% of patients come to see a doctor with this symptom. Surgical treatment is one of the important treatment methods for mammary tumors, including fibroadenoma resection, mammary duct dissection, etc. Before and after the surgery of mammary tumors, it is necessary to take a sample biopsy of the diseased tissue as an important basis for pathological diagnosis.

[0003] Publication No. CN116584980A discloses a mammary tumor sampler, including: a sampling cylinder, a negative pressure assembly, a cutting assembly, and a moving assembly. By holding the sampling cylinder and making the through hole on the cutting cylinder contact the tumor surface, and then generating negative pressure in the second installation cavity through the negative pressure assembly. At this time, the negative pressure generated in the second installation cavity can suck a part of the tumor into the cutting cylinder through the through hole. Then, by pressing the cutting assembly, the cutting blade can move horizontally to cut off the tumor located in the through hole, and make the cut tumor specimen located in the cutting cylinder. Then, by rotating the moving assembly, the rotation of the moving assembly can drive the tumor specimen in the cutting cylinder to move, so that the obtained tumor specimen is separated from the through hole. Furthermore, the above steps can be repeated to sample the tumor again, which is convenient for multiple samplings and improves the sampling efficiency.

[0004] The existing sampler needs to replace the sampler or take out the sample in the sampler after taking one sample before taking another sample, which is more troublesome to use and reduces the sampling efficiency. The new sampler can perform multiple samplings, but the sampling process requires operating multiple components, and the operation is relatively complex. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a sampler to solve the problems existing in the above background art.

[0006] The present invention provides the following technical solution: A sampler, including a sampler, wherein a stretching rod is movably connected inside the sampler, a sealing disc is fixedly connected to the side of the stretching rod, a spring damper is fixedly connected to the top of the sealing disc, the other end of the spring damper is fixedly connected to the sampler, a connecting rod is fixedly connected to the bottom of the stretching rod, a driving device is arranged at the bottom of the connecting rod, the driving device includes a device housing, a connecting disc and a first gear are fixedly connected inside the device housing, an upper connecting ring is fixedly connected to the bottom of the connecting disc, a lower connecting ring is fixedly connected to the top of the first gear, a movable block is fixedly connected to the side of the connecting rod, the movable block is arranged between the upper connecting ring and the lower connecting ring and is movably connected to the upper connecting ring and the lower connecting ring, a second gear is meshed and connected to the side of the first gear, a connecting shaft is fixedly connected to the bottom of the second gear, a runner is fixedly connected to the bottom of the connecting shaft, a rotating rod is rotatably connected to the bottom of the runner, a movable plate is rotatably connected to the rotating rod, the movable plate performs a horizontal movement, a second fixing block and a first fixing block are fixedly connected to the movable plate, a connecting disc is arranged at the bottom of the first gear, a bottom connecting block is fixedly connected to the bottom of the connecting disc, a driving shaft is fixedly connected to the center position at the bottom of the bottom connecting block, and a cutting device is arranged at the bottom of the driving device;

[0007] When in use, when the connecting rod moves upward, it drives the movable block on the connecting rod to move upward. During the movement of the movable block, it contacts the upper connecting ring and gives a lateral force to the upper connecting ring, causing the upper connecting ring to perform a rotational movement. When the connecting rod moves downward, at this time, the movable block is driven by the connecting rod to move to the top groove of the upper connecting ring. When moving downward, the movable block will contact the lower connecting ring at the bottom. At this time, the movable block has passed over the tip part on the lower connecting ring and drives the lower connecting ring to rotate during the downward movement. During the entire process of the connecting rod moving up and down, the connecting disc and the first gear will perform a rotational movement in the same direction;

[0008] When the upper connecting ring drives the connecting disc to rotate, the connecting disc drives the first gear and the lower connecting ring to rotate, the lower connecting ring drives the second gear to rotate, the second gear drives the connecting shaft and the runner to rotate, the runner drives the rotating rod rotatably connected to the bottom to rotate, the rotating rod drives the movable plate to perform a linear reciprocating movement, and the movable plate cooperates with the bottom connecting block fixedly connected to the bottom of the driving shaft through the first fixing block and the second fixing block fixedly connected thereto, driving the bottom connecting block and the driving shaft fixedly connected to the bottom to perform an intermittent rotational movement, and driving the cutting device to sample the tumor through the driving device.

[0009] Further, a turntable is rotatably connected to the top of the device housing, a connecting seat is fixedly connected to the top of the turntable, and the connecting seat is fixedly connected to the sampler.

[0010] Furthermore, the cutting device includes a rotating shaft fixedly connected to a driving shaft. A collection box housing is fixedly connected to the side of the rotating shaft. A collection cavity is formed on the side of the collection box housing. A blade is fixedly connected to the bottom side of the collection box housing.

[0011] Furthermore, a chassis is fixedly connected to the bottom of the sampler. The chassis includes an outer shell plate. A sampling groove is formed on the outer shell plate. The blade is movably connected to the sampling groove.

[0012] Furthermore, a plurality of blood grooves are formed on the top of the outer shell plate. A collection groove is formed at the center of the outer shell plate. The blood grooves communicate with the collection groove. The bottom of the blood groove is inclined and gradually rises from the bottom end face of the collection groove to the blood groove, facilitating the flow of liquid from the blood groove into the collection groove during cutting and avoiding contamination of other samples.

[0013] Furthermore, a cover plate is threadedly connected to the bottom of the collection groove, facilitating opening for cleaning.

[0014] Furthermore, the position of the first fixing block on the movable plate is biased towards the driving shaft direction and towards the rotating rod direction. The distance between the first fixing block and the second fixing block is the same as the distance between the bottom connecting blocks. Circular chamfers are provided on the inner side surfaces of the second fixing block and the first fixing block. The rotating rod is arranged on the runner and not at the exact center. During movement, the second fixing block contacts the bottom connecting block and drives the bottom connecting block to rotate. When the second fixing block is inserted into the gap between the bottom connecting blocks, the movable plate moves to the end point, and then the movable plate starts to move in the reverse direction. The first fixing block contacts the bottom connecting block and drives the bottom connecting block to rotate until the first fixing block moves into the gap between the bottom connecting blocks. At this time, the movable plate moves to the other end, and then starts to reciprocate.

[0015] Furthermore, a grip is fixedly connected to the top of the stretching rod.

[0016] Align the sampling groove on the chassis with the sampling point. By holding the grip and pulling the stretching rod upward, the sealing disk fixedly connected to the stretching rod is driven to move upward, creating negative pressure inside the sampler, sucking a part of the structure on the tumor into the sampling groove, and driving the driving device to move through the stretching rod, thereby driving the cutting device to slowly rotate on the chassis. When the stretching rod is pulled to the maximum position, the cutting device just cuts the sample. Release the stretching rod. At this time, the driving device drives the cutting device to continue to rotate unidirectionally, facilitating the next sampling.

[0017] Beneficial effects:

[0018] 1. For this sampler, align the sampling slot on the chassis with the sampling point. Hold the handle and pull the stretching rod upward. This drives the sealing disc fixedly connected to the stretching rod to move upward, creating negative pressure inside the sampler. Part of the structure on the tumor is sucked into the sampling slot. Then, drive the driving device to move through the stretching rod, and further drive the cutting device to slowly rotate on the chassis. When the stretching rod is pulled to the maximum position, the cutting device just cuts the sample. Release the stretching rod. At this time, drive the cutting device to continue to rotate unidirectionally through the driving device, enabling multiple samplings, and the operation of the device is simple.
