Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a laryngeal microscopic CO2 laser surgery device. Background Art

[0002] As we all know, with the continuous advancement of science and technology, the indications for minimally invasive surgery for ENT lesions have gradually expanded. Among them, laryngeal microscopic CO2 laser surgery refers to a minimally invasive technique that uses a surgical microscope to clearly display the laryngeal structure and then uses a CO2 laser to remove or vaporize the lesion, thereby clearing the lesion, reducing tissue damage, protecting organ function, and allowing the patient to recover health as soon as possible. Its scope of application includes vocal cord polyps, vocal cord leukoplakia, laryngeal papilloma, early laryngeal cancer, etc.

[0003] In real life, a large amount of smoke is generated during the CO2 laser surgery to remove or vaporize the diseased tissue. On the one hand, it blurs the surgical field of view, greatly affects the accuracy of the surgical operation, and prolongs the operation time. On the other hand, it also increases the risk of the operator inhaling smoke and affecting their health. Currently, conventional suction devices are used to remove smoke during surgery. However, because tissue forceps need to be inserted at the same time to pull the diseased tissue, the operating space and field of view under the supported laryngoscope are very limited, which often brings many inconveniences to the surgery. Therefore, the practicality is not very good and there is room for improvement. Utility Model Content

[0013] (III) Beneficial effects

[0014] Compared with the prior art, the utility model provides a laryngeal microscopic CO2 laser surgery device, which has the following beneficial effects:

[0015] The laryngeal microscopic CO2 laser surgical device uses tissue forceps to pull foreign bodies, and secretions or blood generated during the operation are absorbed by the suction force generated by the collection device and sucked away through the suction tube, thereby avoiding the situation where the secretions block the field of vision. At the same time, according to the measuring rod on one side of the dredging rod, the outer tube can be controlled to maintain a safe distance from the inner wall of the throat when moving, thereby avoiding the edge of the tissue forceps touching the inner wall of the throat when moving, thereby improving the surgical effect to a certain extent, and when the suction tube is blocked, the dredging rod can be used to dredge it, which improves the practicality to a certain extent overall.
