[0002] In neurosurgery, gelatin sponge, as a key material, plays a crucial role due to its unique physical properties and wide range of applications, especially the 6cm*2cm*0.5cm gelatin sponge used in our unit, which is often used with brain cotton to optimize surgical results. In the traditional use method, gelatin sponge needs to be finely cut into thin slices by a large round blade. This process aims to make it evenly cover the brain cotton soaked in physiological saline and flattened, thus forming a protective layer that effectively prevents direct contact between brain cotton and brain tissue, thereby avoiding brain tissue adhesion caused by long-term contact and reducing unnecessary bleeding and tissue damage risk.

[0003] However, the current preparation process of gelatin sponge slices faces many challenges. First, gelatin sponge is white, soft and porous, and softens quickly when it comes into contact with water. This property, while beneficial for its application in surgery, also increases the complexity of the operation. Especially when there is moisture on the surface of the glove or blade, it will significantly increase the difficulty of cutting and affect the operation efficiency. Second, the cutting process requires high technical skills, and the operator needs to have skilled knife work to ensure that the thickness of each gelatin sponge is uniform, otherwise it will directly affect its use effect and cause inconvenience in the operation process. In addition, the thinned gelatin sponge is extremely thin and easy to stick to the surface of the glove, blade or other objects during preparation, further increasing the difficulty of preparation, requiring the operator to have high patience, care and abundant energy.

[0028] Example 1

[0029] like Figure 1-4 As shown, an embodiment of the present application provides a gelatin sponge slicer, comprising a left fan 1 and a right fan 2, which are foldably connected so as to be split open. A gelatin sponge groove 6 is defined on each of the opposing sides of the left fan 1 and the right fan 2 for accommodating gelatin sponge. The slicer also includes a cutting tool 7. The left fan 1 and the right fan 2 each have a plurality of evenly spaced cutting spaces, into which the cutting tool 7 can enter the gelatin sponge groove 6, allowing the cutting tool 7 to enter the cutting spaces and evenly cut the gelatin sponge.

[0030] Specifically, the left leaf 1 and the right leaf 2 are symmetrically arranged about their folded overlapping parts, and are preferably of a rectangular structure, made of rust-proof hard materials such as stainless steel and plastic.

[0031] In a specific embodiment, the left leaf 1 and the right leaf 2 are connected by any of the following connection methods: hinge connection, flexible material connection, magnetic connection, slide rail connection, etc. It should be noted that any connection method that can achieve the left and right leaf opening can be considered within the scope of protection of this application.

[0032] In a specific embodiment, the shape of the gelatin sponge groove 6 is the same as that of the gelatin sponge, that is, the gelatin sponge is a rectangular structure, and correspondingly, the gelatin sponge groove 6 is a rectangular groove structure.

[0033] Specifically, the structure adopted for forming the cutting space is: the left fan 1 and the right fan 2 are both composed of a number of partition blades 3 stacked at equal intervals, and there is a partition space between every two adjacent partition blades 3 to form a number of uniform partition spaces, which are the cutting spaces, and the partition spaces are connected to the gelatin sponge groove 6; among them, several partition blades 3 have at least one side edge as a loose edge 4.

[0034] During slicing, the gelatin sponge is placed in the gelatin sponge groove 6, and the cutting tool 7 enters the separation space from the loose edge 4 to evenly cut the gelatin sponge into thin slices.

[0035] A viewing window 8 is provided on the opposite side of the left and right sashes 1 and 2, communicating with the gelatin sponge slot 6. This window 8 facilitates the smooth extrusion of thin gelatin sponge sheets from the gelatin sponge slot 6 using the handle of a cutting tool 7. Preferably, four sheets of gelatin sponge can be placed simultaneously when the left and right sashes 1 and 2 are closed.

[0036] In this embodiment, two gelatin sponges can be stacked in the gelatin sponge grooves 6 of the left fan 1 and the right fan 2 along the depth direction of the grooves.

[0037] More specifically, the left sash 1 and the right sash 2 each include five partition blades 3, which are equidistantly spaced to form four evenly spaced compartments for the cutting tool to enter. Furthermore, to reserve sufficient space for the viewing window 8, the outermost partition blade 3 can be thickened, and the viewing window 8 is provided on this thickened partition blade 3.

[0038] At the same time, the length and width of the gelatin sponge groove 6 are adapted to the length and width of one gelatin sponge, and the depth of the gelatin sponge groove 6 is adapted to the thickness of two gelatin sponges. It should be noted that the viewing window 8 is smaller than the gelatin sponge groove 6. In other embodiments, the gelatin sponge groove 6 can also be lengthened according to actual use requirements.

[0039] At this time, when the gelatin sponge is cut using a slicer, four pieces of gelatin sponge can be evenly cut at the same time.

[0040] In a specific embodiment, to ensure that the blade of the cutting tool 7 can enter each partition space for cutting, the horizontal spacing of each partition space is not less than the thickness of the blade of the cutting tool 7. Preferably, the horizontal spacing of each partition space is equal to the thickness of the blade of the cutting tool 7.

[0041] In one embodiment, the sides of the partition blades 3 on the left and right leaves 1 and 2, except for the open edge 4, are all closed edges 5. The open edge 4 is for the cutting tool 7 to enter and complete the cutting; the closed edge 5 is provided to effectively prevent the blade from protruding from the edge during operation and causing accidental injury.

[0042] Furthermore, the partition blades 3 of the left fan 1 and the right fan 2 respectively have two raveled edges 4 , the two raveled edges 4 are adjacent to each other, and the two side surfaces other than the raveled edges 4 are closed edges 5 .

[0043] In a specific embodiment, one of the joint edges 5 of the separating blades 3 of the left fan 1 and the right fan 2 is provided with a handle 9. The provision of the handle 9 can provide a gripping space for the operator to hold the slicer.

[0044] In one embodiment, the cutting tool 7 includes a handle and a blade (not shown). A utility knife may be used, and the blade is replaceable, meaning the blade is detachably connected to the handle. The blade can be stored in the handle to prevent injury. In one possible embodiment, the blade is connected to the handle via a slidable member, which is secured to the slidable member of the handle by bolts. The blade can be replaced simply by removing and installing the bolts.

[0045] Example 2

[0046] This embodiment may refer to embodiment 1, and the difference from embodiment 1 is that two gelatin sponges (not shown in the figure) can be placed side by side in the gelatin sponge groove 6 of the left fan 1 and the right fan 2 along the width direction of the groove.

[0047] Specifically, the left sash 1 and the right sash 2 each include three partition blades 3, which are equidistantly spaced to form two uniformly spaced compartments for the cutting tool to enter. Furthermore, to reserve sufficient space for the viewing window 8, the outermost partition blade 3 can also be thickened, and the viewing window 8 can be opened on this thickened partition blade 3.

[0048] At the same time, the length and depth of the gelatin sponge groove 6 are adapted to the length and thickness of one gelatin sponge, and the width of the gelatin sponge groove 6 is adapted to the width of two gelatin sponges.

[0049] At this time, when the gelatin sponge is cut using a slicer, four pieces of gelatin sponge can also be evenly cut at the same time.

[0050] The specific working principle of the gelatin sponge slicer of this application is:

[0051] Open the left and right fans, and place the gelatin sponge adaptively in the gelatin sponge groove 6, with two pieces placed on the left and right fans respectively. Then close the left and right fans, and the blade of the cutting tool 7 enters the separation space until it reaches the gelatin sponge groove 6. Under the guidance of the separation space, the gelatin sponge placed in the groove is cut. Four pieces of gelatin sponge can be cut at the same time, and each piece of gelatin sponge is cut into three uniform gelatin sponge slices. Then open the left and right fans, use the handle of the cutting tool 7 to enter from the visual window 8, and push the gelatin sponge slices out of the gelatin sponge groove 6 to complete the uniform cutting of the gelatin sponge.

[0052] The slicer is used to assist in the cutting of gelatin sponge, achieving multiple slices; there is no need to hold the gelatin sponge directly, avoiding the risk of cuts; and the effect of moist gloves on the gelatin sponge is avoided; the gelatin sponge can be cut evenly, quickly and safely.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
