Description

Technical Field

[0001] The utility model relates to the technical field of gelatin sponge compression, and in particular to a gelatin sponge compression cutter. Background Art

[0002] my country has entered the era of precision demand, and the concept of precision medicine is accelerating the development of the medical and health system. In addition to having obvious technical advantages, advanced instruments and equipment and efficient teamwork are also the key to achieving precision. At present, gelatin sponge is used frequently in many otolaryngology surgeries. It is a collagen hemostatic agent and a protein with high tensile strength. It can seal ruptured blood vessels and activate platelets to achieve the purpose of hemostasis. It is required for packing in mastoidectomy, tympanoplasty, external ear canal plasty and external ear canal trauma. The use of gelatin sponge patching and bridging method to treat traumatic tympanic membrane perforation has significant effect. In nasal and sinus surgery, the use of gelatin sponge for packing can help relieve the patient's pain. The effect of packing the middle nasal meatus is accurate, has a certain safety, and has a low risk of postoperative bleeding, which is worthy of clinical adoption. In summary, it is widely used in ear and nose surgery with its advantages of economy, effectiveness and risk-free. However, the existing specifications of gelatin sponge are 60mm×20mm5mm in width, while in some surgeries, in order to better expose the surgical field, support, compress hemostasis, reduce damage, etc., specifications such as 1mm×1mm×0.39mm, 2mm×2mm×0.39mm are required. Although there are special finished sponge particles on the market, the price is as high as one thousand yuan per package, which limits clinical use. However, manual compression and cutting have too many disadvantages. For example, when gelatin sponge particles are needed in surgery, nurses use hemostatic forceps to squeeze them several times to make them thinner, and then use scissors to estimate and cut the specifications suitable for the surgery. There are many problems, such as: multiple compressions are required, which is time-consuming; uneven force causes the surface to be uneven, and the thickness does not meet the surgical requirements due to too light force, and it is easy to break if it is too heavy; estimated cutting, the specifications are not accurate, the surgical requirements are not met or the surgical effect is affected; when cutting too small particles, it is easy to cut the front end of the glove, and the glove dandruff is mixed into the particles, which destroys the sterility principle and has many hidden dangers. So how to accurately, efficiently, safely and conveniently, "different for different people and different for different surgeries", improve surgical results and enhance doctor satisfaction have become issues of concern to operating room nurses and otolaryngologists. In view of the problems existing in the above-mentioned prior art, it is necessary to study and design a new type of gelatin sponge compression cutter to overcome the problems existing in the prior art.
