Description

Technical Field

[0001] The utility model relates to a tissue grinding device, belonging to the technical field of medical equipment. Background Art

[0002] Animal tissues can be divided into four categories: epithelial tissue, connective tissue, muscle tissue and nervous tissue according to their common characteristics in origin, morphological structure and function. In animal tissue related experiments, crushing and grinding animal tissues is a relatively critical step. For example, in the study of the therapeutic potential of Anemarrhena saponin B for severe acute pancreatitis, after a set number of mice were stabilized by a series of drug injections and other operations, the abdominal pancreatic tissue sampling study was carried out. The experimental steps included refrigerated storage of the sampled mouse abdominal pancreatic tissue, followed by physical testing, crushing and grinding and other parameter testing to obtain first-hand relevant experimental data.

[0003] There are many kinds of existing tissue grinding devices, all of which use mechanical principles to use blades, grinding rollers, grinding blocks, etc. to crush and grind animal tissues. In order to improve the grinding efficiency, the grinding mechanism is additionally vibrated by a power device to ensure the grinding efficiency. This makes the device bloated and requires two motors to drive the function, and the operation and control are relatively complicated. In addition, during the grinding and crushing process, the device is generally crushed and ground at room temperature without any constant temperature or low temperature, which makes the tissue easy to oxidize and affects the final test experimental data results. Summary of the invention

[0004] In view of the shortcomings of the above-mentioned prior art, the utility model proposes a tissue grinding device, which can be used to crush and grind animal tissues, and the grinding temperature environment can be thermostatically controlled according to the experimental data collection requirements to avoid factors such as tissue oxidation during the grinding process that may affect the final experimental collection data.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the utility model is as follows: a tissue grinding device, comprising a grinding body with a grinding cavity inside and a cover body detachably connected thereto, characterized in that: the outer wall of the grinding body has a hollow interlayer, the grinding body has a circulation channel extending from the outer side of the outer wall to the hollow interlayer, the circulation channel connects the hollow interlayer with an external constant temperature medium for circulation; the cavity wall between the hollow interlayer and the grinding cavity is formed of a heat-conducting material, and the wall thickness of the cavity wall is uniformly set;

[0006] A fixed beam is horizontally fixed on the inner wall of the cover body, and a driving motor is floatingly arranged above the fixed beam through a movable beam. The driving motor is rigidly fixed on the movable beam, and the driving shaft of the driving motor passes through the movable beam and the fixed beam in sequence downward and is fixedly connected to the grinding balls in the grinding chamber; the movable beam is supported on the fixed beam by a plurality of compression springs, and the compression springs make the grinding balls press against the spherical inner bottom of the grinding chamber.

[0007] Furthermore, the cover has a limiting groove on the opposite side of the inner wall, and the movable beam has a limiting block fitted in the limiting groove. The movable beam moves up and down in the limiting groove along the axial direction of the driving shaft of the driving motor.

[0008] Furthermore, the cover body has an end cover at the rear end, the power line of the drive motor passes through the end cover and is connected to an external power supply, and a built-in button switch is provided on the end cover, and the built-in button switch is electrically connected to the control end of the drive motor.

[0009] Furthermore, the upper inner portion of the grinding body has an annular step, and a circular baffle is gapped thereon. The circular baffle has a slit for the drive shaft to slide laterally to the center position, and the slit is formed by extending from the circumference of the circular baffle toward the center of the circle.

[0010] Furthermore, the movable beam has a movable gap in both the horizontal groove depth direction and the horizontal groove side direction of the limiting groove portion.

[0011] The beneficial effects of the utility model are as follows: by combining a driving motor with a compression spring, a driving motor can be used to drive the grinding balls to oscillate and grind animal tissues; by utilizing a circulation channel, an external constant temperature medium can be circulated in the hollow interlayer to ensure that the entire grinding temperature environment is constant, thereby avoiding oxidation of the ground tissue and other situations that affect the experimental data errors; at the same time, the grinding environment temperature can be regulated according to the needs of the experimenters to meet the grinding experiments under different grinding temperature conditions, thereby improving the versatility and applicability of the grinding device; by utilizing the cooperation between the grinding balls and the spherical bottom of the grinding cavity, the movable gap of the movable beam in the limiting groove, and the flexible characteristics of the spring, the driving motor has more degrees of freedom when driving the grinding balls to grind, thereby causing the grinding balls to produce a small range of offset swings during the oscillating grinding process, thereby further improving the grinding efficiency and grinding quality of the entire device. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a schematic diagram of the structure of the utility model. DETAILED DESCRIPTION

[0013] The present invention will be further described in detail below in conjunction with specific embodiments and accompanying drawings.

[0014] A kind of Figure 1 The tissue grinding device shown comprises a grinding body 1 having a grinding cavity 4 therein and a cover body 2 detachably connected thereto, the outer wall of the grinding body 1 having a hollow interlayer 3, the grinding body 1 having circulation channels 11 and 12 extending from the outer side of the outer wall to the hollow interlayer 3, the circulation channels 11 and 12 connecting the hollow interlayer 3 with an external constant temperature medium for circulation; the cavity wall between the hollow interlayer 3 and the grinding cavity 4 is formed of a heat-conducting material, and the wall thickness of the cavity wall is uniformly set;

[0015] A fixed beam 21 is horizontally fixed to the inner wall of the cover body 2, and a driving motor 25 is floatingly arranged above the fixed beam 21 through a movable beam 23. The driving motor 25 is rigidly fixed on the movable beam 23, and the driving shaft of the driving motor 25 passes through the movable beam 23 and the fixed beam 21 in sequence downward and is fixedly connected to the grinding balls 5 in the grinding chamber 4; the movable beam 23 is supported on the fixed beam 21 by a plurality of compression springs 24, and the compression springs 24 make the grinding balls 5 abut against the spherical inner bottom of the grinding chamber 4.

[0016] The utility model utilizes a driving motor in combination with a compression spring, so that a driving motor can drive the grinding balls to oscillate and grind the animal tissue; a circulation channel is utilized to allow an external constant temperature medium to circulate in the hollow interlayer to ensure that the entire grinding temperature environment is constant, thereby avoiding situations such as oxidation of the ground tissue that may affect the experimental data error; at the same time, the grinding environment temperature can be regulated according to the needs of the experimenters to meet the grinding experiments under different grinding temperature conditions, thereby improving the versatility and applicability of the grinding device.

On the one hand, it drives the grinding ball 5 to vibrate up and down in a small range. On the other hand, due to the existence of the movable gap, the grinding ball 5 will deflect in a small range, which is beneficial to the grinding of animal tissues and improves its efficiency and quality.
