Description

Quick positioner of cricothyroid membrane pjncture needle Technical Field The invention relates to the technical field of medical appliances, in particular to a rapid positioning device for a cricothyroid membrane puncture needle. Background The cricothyroid membrane puncture is a key first-aid technology for critical symptoms such as acute laryngeal obstruction, wherein the accurate positioning of puncture points directly determines the success or failure of rescue. At present, clinical medical staff mainly rely on palpating the anatomical marks before the neck to carry out positioning, but under the complicated conditions that the patient has obesity, neck swelling or unclear anatomical structure or external trauma leads to the damage of the neck structure and the like, the body surface marks are difficult to identify, the positioning accuracy is highly dependent on the experience of an operator, and puncture failure is easy to cause or rescue opportunity is delayed. The existing auxiliary device focuses on mechanical fixation or static template comparison, is difficult to adapt to individual differences and body position changes of patients, and cannot effectively solve the problem of target point visualization under complex body surface conditions. At present, no auxiliary device for positioning the puncture point by adopting a laser irradiation mode exists. The cricothyroid membrane has natural light transmittance, laser can effectively penetrate through the membrane layer to form a clear light transmission area, and the physiological characteristic provides an ideal tissue window for laser positioning. The light guide irradiation technology focuses laser on the cricoid film to form visible light spots through the light guide system, so that the traditional palpation positioning can be converted into visual optical guidance, the dependence on the experience of an operator is obviously reduced, and a new technical path is provided for accurate positioning. However, the application of the technology to a cricothyroid membrane puncture scene still faces challenges, the stable adsorption of the device on the emergency site needs to be ensured, the deviation of laser marks caused by equipment shaking is avoided, a flexible and adjustable mechanical arm needs to be designed to adapt to neck shapes of different patients, the accurate projection of laser to a target spot is ensured, and meanwhile, the portability and the operation efficiency of the device are also required to be considered. Therefore, a device capable of integrating stable support, flexible adjustment and auxiliary optical positioning is developed, so that the positioning efficiency and the operation convenience in the process of cricothyroid membrane puncture are improved, and the device has important clinical value for improving the success rate of puncture.
