DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-4 As shown, a precise quantitative sampling device for pathology department comprises a fixed block 1, the bottom of the fixed block 1 is fixedly connected to an outer tube 2, a sampling mechanism 3 is arranged inside the fixed block 1, the sampling mechanism 3 comprises an observation chamber 4, the bottom of the observation chamber 4 is fixedly connected to the fixed block 1, a top side of the fixed block 1 is fixedly connected to a threaded sleeve 5, the inner side of the threaded sleeve 5 is meshedly connected to a lifting block 6, the inner side of the lifting block 6 is rotatably connected to a knob 7, a driving wheel 8 is fixedly connected to the middle part of the knob 7, the bottom of the knob 7 is movably connected to a spring 10, the bottom of the spring 10 is movably connected to the fixed block 1, the inner side of the fixed block 1 is rotatably connected to a driven wheel 11, the inner side of the driven wheel 11 is meshedly connected to a telescopic rod 13, the bottom of the telescopic rod 13 is fixedly connected to a needle 14, the middle part of the telescopic rod 13 is slidably connected to the fixed block 1, and the top of the telescopic rod 13 is slidably connected to the inner wall of the observation chamber 4.

[0022] In this embodiment, the middle of the knob 7 is fixedly connected to the driving wheel 2 9, the inner side of the fixed block 1 is rotatably connected to the driven wheel 2 12, the bottom of the driven wheel 2 12 is fixedly connected to the cutter 15, and the outer side of the cutter 15 is rotatably connected to the outer tube 2.

[0023] The cutter 15 can be used to cut the patient's soft tissue, thereby sampling the diseased soft tissue.

[0024] In this embodiment, a deep hole is formed on the inner side of the cutter 15, and the bottom end of the cutter 15 is an annular blade.

[0025] The inner side of the cutter 15 is provided with a deep hole, which can accommodate the telescopic rod 13 to move inside, thereby facilitating sampling.

[0026] In this embodiment, an empty groove is opened inside the fixing block 1 , and a round hole is opened on the top of one side of the fixing block 1 , and a round hole is opened on the top of the other side of the fixing block 1 that passes through to the bottom.

[0027] The empty slot inside the fixing block 1 can provide working space for other components and can protect the internal components.

[0028] In this embodiment, a circular protrusion is provided on the top of the telescopic rod 13 , and sliding grooves are provided on both sides of the upper portion of the telescopic rod 13 .

[0029] The telescopic rod 13 is constrained by the fixed block 1 through the slide slot, so that the telescopic rod 13 can only move up and down.

[0030] In this embodiment, a thread is provided at the bottom of the lifting block 6 , and a round hole is opened at the top of the lifting block 6 and penetrates to the bottom.

[0031] By adjusting the height of the lifting block 6, the meshing state between the gears can be controlled, thereby switching between liquid extraction and soft tissue extraction.

[0032] In this embodiment, a circular hole is opened at the bottom of the observation chamber 4, and scale lines are arranged on the outer wall of the observation chamber 4.

[0033] By observing the position of the circular protrusion of the telescopic rod 13 on the scale line of the observation chamber 4, quantitative sampling can be facilitated. The observation chamber 4 is transparent, which facilitates observation of its interior.

[0034] It should be noted that the utility model is a precise quantitative sampling device for pathology, which has the function of taking liquid samples and soft tissue samples when in use. The specific implementation method is to rotate the knob 7, and the knob 7 will drive the driving wheel 1 8 and the driving wheel 2 9 to rotate. When the driving wheel 1 8 rotates, it will drive the driven wheel 1 11 to rotate. When the driven wheel 1 11 rotates, it will drive the telescopic rod 13 to move through the action of the thread. The telescopic rod 13 can only move up and down due to the constraint of the fixed block 1, and the movement direction of the telescopic rod 13 can be controlled by rotating the knob 7 in different directions.

[0035] After the needle 14 of the sampling device is inserted into the patient's part where sampling is required, the knob 7 is turned to control the telescopic rod 13 to move upward. During the upward movement of the telescopic rod 13, the needle 14 is driven to move upward together. After the needle 14 moves up a certain distance, a cavity with a lower pressure will be formed inside the bottom of the cutter 15. The liquid at the sampling location will enter the inside of the cutter 15 under the action of pressure. When the telescopic rod 13 moves upward, the protrusion on the top will be driven to move upward together. By observing the relative position of the top protrusion moving to the scale line of the observation chamber 4, the sampling amount can be controlled. After taking a suitable amount of sample, the sampling device is pulled out, and then the telescopic rod 13 is controlled to move in the opposite direction to squeeze the liquid into the storage container to complete the liquid sampling.

[0036] When it is necessary to take a soft tissue sample, the lifting block 6 is rotated to move it downward, and the knob 7 is pressed downward during the downward movement. When the knob 7 moves downward, the spring 10 is squeezed to shrink it. When the knob 7 moves downward, it will drive the driving wheel 1 8 and the driving wheel 2 9 to move together. After moving a certain distance, the driving wheel 1 8 will mesh with the driven wheel 1 11, and the driving wheel 2 9 will mesh with the driven wheel 2 12. At this time, the knob 7 is rotated to drive the driving wheel 1 8 and the driving wheel 2 9 to rotate. When the driving wheel 1 8 and the driving wheel 2 9 rotate, they will drive the driven wheel 1 11 and the driven wheel 2 12 to rotate. When the driven wheel 2 12 rotates, it will drive the cutter 15 to rotate.

[0037] After the needle 14 is inserted into the sampling position, the control knob 7 is moved upward, and the cutter 15 will rotate synchronously with the knob 7, and cut the soft tissue through the opening at the bottom while rotating. The cut soft tissue will enter the inside of the cutter 15 under the action of the pressure difference. After cutting an appropriate amount of sample, the sampling device is slightly retracted, and the bottom is adjusted to a certain angle and pressed down again to cut off the connection between the soft tissue sample and the affected part, and then the sampling device is pulled out, and the telescopic rod 13 is moved in the opposite direction to squeeze the sample into the storage container to complete the soft tissue sampling. It is necessary to switch to the liquid collection mode, by controlling the lifting block 6 to move upward, the knob 7 will move upward under the action of the spring 10, so that the sampling device is restored to the state where the driving wheel 2 9 and the driven wheel 1 11 are meshed;

[0038] By providing the sampling mechanism 3 and the cutter 15, two sampling modes are realized to meet the needs of pathology inspection. Meanwhile, the operation is simple and the sampling amount is easy to control, thereby improving the accuracy and efficiency of pathology inspection.

[0039] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
