Description

Technical Field

[0001] The utility model belongs to the technical field of medicine grinding, in particular to a medicine grinding device for hepatobiliary surgery. Background Art

[0002] Hepatobiliary surgical drugs (such as ursodeoxycholic acid preparations, traditional Chinese medicine litholytic powders, liver-protecting extracts, etc.) generally have three characteristics: complex physical properties, sensitive active ingredients, and high bioavailability requirements.

[0003] Taking the traditional Chinese medicine powder commonly used in clinical treatment of hepatobiliary stones as an example, its formula often contains hard mineral herbs (such as ochre and oyster) and tough plant herbs (such as Artemisia capillaris and Lysimachia chinensis). These herbs need to be ground to a fineness of 600-800 mesh (approximately 10-25 microns) to achieve rapid dissolution and release of the active ingredients. Furthermore, the fat-soluble components of liver-protecting drugs (such as silybin and diammonium glycyrrhizate) are easily inactivated by local high-temperature oxidation during the grinding process, resulting in reduced efficacy. Current drug grinding technology has two major flaws that need to be improved:

[0004] (1) Traditional ball mills or mortars rely on a single rotational extrusion action, which results in poor grinding uniformity for compound medicinal materials with large hardness differences (such as mineral medicinal materials). The large particles after grinding account for a large proportion, which reduces the lithotripsy efficiency after oral administration and is prone to gastrointestinal mucosal irritation.

[0005] (2) Although high-speed mechanical grinding can improve fineness, the temperature inside the grinding jar rises, resulting in an excessively high decomposition rate of heat-sensitive components such as ursodeoxycholic acid. The adenosine preparation commonly used by patients after hepatobiliary surgery undergoes a molecular configuration change in an environment above 60°C, losing its bile metabolism regulation function. In addition, oil-containing medicinal materials (such as turmeric and Amomum villosum) release oil due to frictional heat during continuous grinding, causing powder agglomeration.

[0006] Therefore, a highly efficient, composite, low-temperature stable and high-grinding fineness drug grinding device for hepatobiliary surgery is needed to solve the above problems. Utility Model Content

[0035] The inner wall of the bottom of outer box 1 is fixedly provided with guide ring 3, the guide ring 3 is provided with guide groove 4, the guide groove 4 is fixedly provided with guide ladder 9, the ball 10 is in rolling contact with the upper wall of guide ladder 9.

[0036] The inner wall of the bottom of outer box 1 is rotatably provided with driving shaft 26, the upper end of driving shaft 26 is coaxially fixedly connected with first grinding roller 7, the outer wall of driving shaft 26 is fixedly provided with conical wind collector 24, the circumferential outer wall of driving shaft 26 is fixedly provided with cooling fan 25, the cooling fan 25 is located in conical wind collector 24, the upper wall of conical wind collector 24 is provided with concentrated air blowing hole 27.

The highest point of the inclined surface of the inclined platform 29 smoothly transitions with the upper wall of the high platform 28, and the lowest point of the inclined surface of the inclined platform 29 smoothly transitions with the upper wall of the low platform 30. The high platform 28 and the inclined platform 29 form a semi-circular shape in a top-down plane, and the guide step 9 as a whole forms a ring shape in a top-down plane.

[0039] When in use, the drug raw material is first fed into the grinding cylinder 2 through the feeding tube 6. After the motor 5 is started, the power of the motor 5 is transmitted to the connecting shaft 17 and the thick gear 14, driving them to rotate. The thick gear 14 drives the first grinding roller 7 to rotate on the one hand, and drives the planetary gear 15 and the second grinding roller 8 to revolve along the track of the gear ring 13 on the other hand. At this time, the first grinding roller 7 and the second grinding roller 8 move in coordination to form the first grinding effect of the drug;

[0040] When the thick gear 14 continues to rotate, the planetary gear 15 drives the second grinding roller 8 to rotate. At this time, the rotation of the first grinding roller 7 and the rotation of the second grinding roller 8 cooperate with each other to perform the second grinding of the medicine;

[0041] When the second grinding roller 8 revolves, its connecting post 11 is driven along with it. The rotation of the connecting post 11 causes the ball 10 to contact the guide step 9. This contact causes the connecting post 11 and the second grinding roller 8 to move upward, thereby compressing the telescopic rod 16 and the spring 20. When the ball 10 leaves the guide step 9, the connecting post 11 and the second grinding roller 8 return to their original position and move downward under the elastic force of the spring 20. This up and down reciprocating motion is combined with the parallel rubbing between the first grinding roller 7 and the second grinding roller 8 to form a third grinding effect for the pharmaceutical raw materials.

[0042] When the first grinding roller 7 rotates, the first grinding roller 7 drives the driving shaft 26 and the heat dissipation fan 25 to rotate. The rotation of the heat dissipation fan 25 generates airflow, and at the same time, the external airflow is transported into the conical air collecting cover 24, and then blown toward the second sealing plate 22 from the centralized blowing hole 27, thereby dissipating heat and cooling the medicinal powder gathered on the upper side of the second sealing plate 22, thereby avoiding adverse effects such as local high temperature caused by high-speed grinding, inactivation of heat-sensitive components, and agglomeration of oil and medicinal material powder;

[0043] After the grinding process is completed, the sealed discharge door is opened to take out the drug powder in the grinding cylinder 2.

[0044] In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to this technical solution without creatively designing them without departing from the inventive purpose of this utility model, they should all fall within the scope of protection of this utility model.
