A kind of epiglottis abscess incision knife

Abstract

The invention relates to the technical field of medical devices, in particular to an epiglottis abscess incision knife, which includes a handle and a protective sleeve, a support structure is arranged on the end of the metal catheter away from the handle, and a knife structure is arranged inside the port of the metal catheter. One end is connected with a knife handle through a guide rod, and an adsorption filter structure is arranged under the tool structure, and one end of the adsorption filter structure is connected with a liquid storage tank and a folding air bag through a catheter in turn, and a second blade is arranged on the lower side of the tool structure, and the adsorption filter structure The upper side is provided with a first blade. The support structure of the present invention supports the oral cavity, the knife structure performs multiple cuts on the abscess, and the liquid storage tank under negative pressure performs one-time adsorption and cleaning of the cut pus and blood through the adsorption and filtration structure, and the quickness of use of the lifting device ensures that The success rate of the operation, while the replacement of the liquid storage tank and the blade housing, is convenient for cleaning and disinfection, and improves the hygienic safety of the device.

Description

technical field [0001] The invention relates to an incision knife, in particular to an epiglottis abscess incision knife, which belongs to the technical field of medical instruments. Background technique [0002] Epiglottis, a medical term, is a visor-shaped structure behind the base of the tongue. It is based on cartilage and covered with mucous membrane. There are left and right paired dimples between the base of the tongue, where bone spurs can easily enter, and behind it is the entrance of the larynx. [0003] The epiglottis is the command system in the throat. The human throat is the only way for food and air to pass. After food is swallowed by the mouth, it enters the esophagus to the stomach through the throat, and air is inhaled from the nasal cavity, and enters the trachea to the lungs through the throat. The cervical esophagus and trachea run side by side, allowing food and gas to go their own way without interfering with each other in an orderly manner. [0004] ...

AI Technical Summary

Problems solved by technology

[0004] Epiglottic cyst is a cystic substance located on the lingual surface of the epiglottis, which can cause foreign body sensation and oppressive feeling in the throat, and easily induce the occurrence of acute epiglottis inflammation. Therefore, once the epiglottis cyst is diagnosed, surgical treatment is required in time. At present, incision is often used Cutting the epiglottic cyst with a knife is a minimally invasive procedure. After general anesthesia is completed, a supporting laryngoscope is inserted from the mouth to the base of the tongue. After seeing the epiglottic cyst, the supporting laryngoscope is fixed to expose the cyst completely. After touching the cyst with the knife head, The cyst is cut and cleaned. If there is bleeding or oozing during the operation, it can be coagulated with a hemostatic key. After the operation, the supporting laryngoscope is removed. A certain support mechanism is needed during the cutting process, and then the abscess is cut. The generated pus needs to be ablated by the mouth itself. For bleeding or oozing, it needs to be cleaned up with another instrument, and it cannot be treated thoroughly at one time, which brings some pain to the patient and cannot guarantee safety and hygiene. It will cause certain infection, and the operation process is also more troublesome
