[0002] During heart surgeries and other procedures, large amounts of ice shavings are needed to cool the heart and other organs. Currently, medical staff use a method of holding an ice block in one hand and a scalpel in the other to scrape sterile ice to obtain ice shavings. However, this operation is time-consuming, labor-intensive, and inefficient. Due to the operating habits of medical staff, the ice blocks are often of varying sizes, requiring additional cutting into ice shavings. In addition, scraping with a bare scalpel can easily cause hand injuries if not handled carefully. Utility Model Content

[0003] The purpose of this invention is to provide a medical ice shaving device to solve the problems of time-consuming and laborious manual ice scraping, poor ice uniformity, and low safety in the existing technology.

[0004] To solve the above problems, the medical ice shaving device involved in this utility model adopts the following technical solution: A medical ice shaving device includes a guide tube for holding ice, a pressure cap, an ice-shaving assembly disposed below the guide tube, and a limiting structure disposed below the guide tube. The pressure cap guide is pressed into the inner cavity of the guide tube and squeezes the ice block downwards when pressed; the limiting structure has a limiting surface that extends into the outer contour range of the inner cavity of the guide tube and is used to cooperate with the upper and lower limiting stops of the ice block, and there is a gap between the limiting surface and the bottom surface of the guide tube. The ice-shaving assembly includes an ice-shaving rod hinged to one side edge of the bottom of the guide tube, with the hinge axis extending vertically. The ice-shaving rod includes a scraping blade section arranged on one side of the hinge axis, the scraping blade section extending horizontally into the gap, and an operating lever section arranged on the other side of the hinge axis or connected to the scraping blade section.

[0005] In a preferred embodiment, the ice-shaving rod is hinged to the guide tube at its center position, and the scraper section and the operating lever section are respectively located on both sides of the hinge axis, with the length of the operating lever section being greater than the length of the scraper section.

[0006] In a preferred embodiment, the extreme points on both sides of the reciprocating swing of the scraper section are outside the outer contour range of the inner cavity of the guide tube.

[0007] In a preferred embodiment, the bottom of the guide tube is connected to a support column for supporting it on a table. There are multiple support columns, which are evenly distributed around the periphery of the guide tube. The area below the guide tube forms a collection space for collecting slush.

[0008] In a preferred embodiment, the limiting structure includes limiting blocks arranged at the two extreme points on both sides of the scraper section, the bottom of the limiting blocks having a flange extending radially inward, and the upper end surface of the flange forming the limiting surface.

[0009] In a preferred embodiment, the limiting structure further includes a guide block connected to the bottom side of the guide cylinder and arranged at the end of the scraper section.

The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0020] Specific embodiments of the medical ice shaving device involved in this utility model are as follows: Figures 1 to 3 As shown, the medical ice shaving device includes a guide tube 1 for holding ice, a pressure cap 2, an ice shaving assembly disposed below the guide tube 1, and a limiting structure disposed below the guide tube 1.

[0021] In this embodiment, the guide tube 1 is a cylindrical structure, adapted to hold cylindrical ice blocks. Of course, in other embodiments, a rectangular structure or a cubic ice block can be used depending on the structure of the ice block; the choice is not limited based on the actual ice block. Furthermore, the size of the ice block is not limited by the inner cavity size of the guide tube 1, but is adapted by the bottom limiting structure. That is, even small ice blocks can be supported and scraped by the bottom limiting structure.

[0022] The bottom side of the guide tube 1 has a support plate 11, and the four periphery of the support plate 11 has support columns 12 for supporting it on the table. There are multiple support columns 12, which are evenly distributed around the periphery of the guide tube 1 at intervals of 7. The bottom of the guide tube 1 forms a collection space for collecting ice slush.

[0023] The aforementioned pressure cap 2 is pressed into the inner cavity of the guide cylinder 1, and is pressed downward to squeeze the ice block. Specifically, in this embodiment, the pressure cap 2 itself is a circular cap with a lifting handle 21 on the top and an anti-slip protrusion 22 on the bottom side for insertion into the ice block. During the process of the pressure cap 2 pressing the ice block downward, the anti-slip protrusion 22 prevents the ice block from moving radially and keeps it in the limiting structure, while ensuring the thickness of the ice block scraped each time.

[0024] The aforementioned limiting structure has a limiting surface 6 extending into the outer contour of the inner cavity of the guide cylinder 1 and used to cooperate with the upper and lower limiting stops of the ice block. There is a gap 7 between the limiting surface 6 and the bottom surface of the guide cylinder 1. That is, after the ice block is placed into the guide cylinder 1, the bottom of the ice block protrudes downwards from the guide cylinder 1 and is stopped and fixed by the limiting surface 6. At this time, the ice block is exposed in the aforementioned gap 7, and this part can be effectively scraped. In actual design, the thickness of the gap 7 is designed to accommodate the sum of the scraping thickness and the thickness of the scraping component, according to the size of the ice slush, ensuring smooth operation of the scraping component and uniform scraping of the ice slush.

[0025] The ice-shaving assembly described above includes an ice-shaving rod 3 hinged to one side edge of the bottom of the guide cylinder 1. The axis of the hinge shaft extends in the vertical direction. The ice-shaving rod 3 includes a scraping blade section 31 arranged on one side of the hinge axis. The scraping blade section 31 extends horizontally into the interval 7. It also includes an operating lever section arranged on the other side of the hinge axis or connected to the scraping blade section 31. The scraping blade section 31 is driven to swing back and forth around the hinge axis to scrape the ice block located in the interval 7 into ice shavings.

[0026] Specifically, in this embodiment, the ice-shaving rod 3 is hinged to the guide cylinder 1 at its center position. The scraping blade section 31 and the operating lever section are respectively located on both sides of the hinge axis. The length of the operating lever section is greater than the length of the scraping blade section 31. This design enables the ice-shaving rod 3 to form a force-saving lever structure as a whole. By swinging the operating lever section, the scraping blade section 31 can perform the scraping operation on the ice.

[0027] In one embodiment, the extreme points on both sides of the reciprocating swing of the scraper section 31 are outside the outer contour of the inner cavity of the guide cylinder 1. The extreme point positions are determined by the blocking action of the limiting structure. When the scraper section 31 reciprocates in interval 7, the swing path of the scraper section 31 is designed to swing out of the outer contour of the inner cavity of the guide cylinder 1 in order to achieve the purpose of uniformly scraping all the bottom surfaces of the ice block.

[0028] In one embodiment, the scraping blade section 31 includes a main blade arranged coaxially with the operating lever section. A row of serrated cutting edges is distributed on both sides of the main blade, which can satisfy reciprocating scraping, reduce the number of swings, and at the same time, scraping on both sides can greatly improve scraping efficiency.

[0029] To further facilitate scraping, a hinge shaft is located at the bottom of the guide cylinder, and a hinged elongated hole 33 is provided in the middle of the ice-shaving rod. The two are movably assembled so that the ice-shaving rod can move along the extension direction of the elongated hole when it swings. This satisfies both scraping and sawing operations, avoiding the problem of not being able to scrape quickly when only swinging.

[0030] Regarding the limiting structure, the aforementioned limiting structure consists of two parts. One part includes limiting blocks 5 arranged at the extreme positions on both sides of the scraper section 31. The bottom of the limiting blocks 5 extends radially inward with a retaining edge, and the upper end surface of the retaining edge constitutes the limiting surface 6. The other part of the limiting structure also includes a guide block 4 connected to the bottom side of the guide cylinder 1 and arranged at the end of the scraper section 31. The inner side of the guide block 4 has an arc-shaped guide groove 41 adapted to the swing path of the end of the scraper section 31, and the bottom edge of the arc-shaped guide groove 41 constitutes the limiting surface 6.

[0031] Meanwhile, in order to prevent excessive accumulation of slush on the limiting surface, a through hole 8 is provided on the limiting surface to allow the scraped slush to leak downwards. The size of the through hole 8 can be relatively large and is not specifically limited.

[0032] That is, the limit block 5 in the limit structure restricts the extreme position of the scraper section 31, and the guide groove supports and limits the vertical movement of the scraper section 31 during its swing. At the same time, the limit surfaces 6 of the two form a gap 7 with the bottom surface of the guide cylinder 1, which can also provide stable limit support for the ice block.

[0033] Finally, it should be noted that the above embodiments are only for illustration and not for limiting the technical solutions of this utility model. Any equivalent substitutions and modifications or partial substitutions that do not depart from the spirit and scope of this utility model should be covered within the scope of protection of the claims of this utility model.
