Problems solved by technology

However, the method of preparing and cutting gelatin sponge particles before operation is old, time-consuming, and laborious. It requires certain experience for cutting personnel, and often the cutting personnel wear sterile gloves, and the scissors sometimes wear sterile rubber gloves during the process of cutting gelatin sponge particles. The rubber is cut into small pieces and mixed into the gelatin sponge particles, so that the prepared gelatin sponge particles are scrapped, and the gelatin sponge particles need to be re-cut, resulting in waste of gelatin sponge (suppository material), duplication of labor by the preparers, and delays in the use of interventional operations and time

Embodiment 1

[0012] like figure 1 , figure 2 As shown, a medical cutting knife includes a fixed body 1 and a blade 2; the blade 2 is fixed on the fixed body 1 and extends below the fixed body 1; the upper part of the blade 2 is square, and positioning blocks 4 are installed on both sides of the square ; The lower part of the blade 2 is an inverted triangle, and the two sides of the inverted triangle of the blade 2 are blades.

[0013] The square part of the blade 2 has a connecting hole 3 for connecting the blade.

[0014] There are at least two blades 2 parallel to each other;

[0015] The distance between the blades 2 is 0.5-2mm.

[0016] When the present invention is used, N groups of blades 2 work together to cut the gelatin sponge into particles of uniform specifications, which can reduce the pollution in the preparation process of the gelatin sponge particles, keep the freshness of the gelatin sponge particles, and reduce the oxidation time of the gelatin sponge particles in the ...

Abstract

The invention provides a medical cutting knife, which comprises a fixed body and a blade, wherein the blade is fixed on the fixed body and is extended out of the lower part of the fixed body. The medical cutting knife can reduce pollution in the process of preparing gelatin sponge particles, keep fresh of the gelatin sponge particles, shorten the oxidation time of the gelatin sponge particles in air, reduce the consumption of gelatin sponge, and save time and labor in cutting.

Description

technical field [0001] The invention belongs to the field of medical gelatin sponge cutting, in particular to a medical cutting knife. Background technique [0002] Vascular minimally invasive interventional therapy has been widely used in various aspects of the medical field. However, the use of embolic agents in embolization therapy is varied, such as polyvinyl alcohol (PVA) embolic agents, sodium alginate (KMG) embolic agents, spring plug embolic agents, etc. These medical materials are expensive, which limits the use of hospitals. Use, patient accepts difficulty. At present, gelatin sponge, an economical and practical embolic agent, has been accepted by the majority of medical staff. Gelatin sponge particles are safe and effective in clinical interventional hemostasis. However, the method of preparing and cutting gelatin sponge particles before operation is old, time-consuming, and laborious. It requires certain experience for cutting personnel, and often the cutting p...
