Nasal cavity hemostat, sinus cavity hemostat and hemostasis operation method

Abstract

The invention relates to a nasal cavity hemostat, a sinus cavity hemostat and a hemostasis operation method. The nasal cavity hemostat comprises a hemostasis airbag, an airway conduit, a nasal vestibule plug, a fixed buckle, an inflating pipe, an indication balloon and an inflation valve, and is characterized in that: one end of the airway conduit is sleeved on the nasal vestibule plug; the fixed buckle is arranged on the nasal vestibule plug; thicknesses of two lateral walls of the hemostasis airbag are not equal. The sinus cavity hemostat comprises a hemostasis airbag, an inflating pipe, an indication balloon and an inflation valve, wherein the hemostasis airbag is of an ovular flat structure matched with the space inside the sinus cavity. The nasal cavity hemostat and the sinus cavity hemostat have the advantages that: the shape of the hemostasis airbag is matched with that of an operated cavity, and can be well attached to the nasal cavity of a patient when used, and hemostasis can be realized by virtue of physical compression to the surface of nasal mucosa; the pressure is uniformly and adjustable, the plug discomfort can be reduced; the contact with a bleeding wound of the nasal cavity can be possibly reduced in inserting and withdrawing processes, and secondary wound can be avoided; the patient can breath through the nasal cavity due to the airway conduit; the operation is convenient, the bleeding time can be shortened, complication can be reduced, and pains of patients can be lightened.

Description

technical field [0001] The invention belongs to the technical field of clinical medicine, and in particular relates to a nasal cavity hemostat, a sinus cavity hemostat and a hemostasis operation method. Background technique [0002] Nasal endoscopic surgery is used to treat chronic sinusitis and nasal polyps. Postoperative nasal and sinus cavities must be packed to stop bleeding. At present, when the above-mentioned operations are performed clinically, hemostatic materials such as gauze or polymer hemostatic sponge are mainly used to fill the nasal cavity or sinus wounds, and the bleeding is stopped by physical compression. The polymer hemostatic sponge widely used clinically is a relatively thick and hard sponge. Before use, the sponge needs to be soaked and softened, and then stuffed into the patient's nasal cavity. When using this method to insert or remove the sponge from the nasal cavity, it will greatly irritate the nasal cavity wound, especially when taking it out, b...

Problems solved by technology

When local pressure is used to stop bleeding, if the pressure is too high, the local blood supply will be seriously affected, which will slow down the local metabolism, which is not conducive to the healing of postoperative wounds, and if the pressure is too small, it will not achieve the purpose of hemostasis
