Holmium laser electric excision system for precisely treating sinus tract

Abstract

The invention relates to a holmium laser electric excision system for precisely treating sinus tract. The holmium laser electric excision system comprises a dilator, a micro intracavitary endoscope, a metal guide wire, a holmium laser device, an electric excision device, and a hydraulic pressure flushing system. The dilator comprises a handle, a connecting rod, and a dilation head. The micro intracavitary endoscope comprises an endoscopic sheath, a hydraulic pressure flushing system, and an endoscopic sheath seat. An instrument passage, a water inlet passage, a water outlet passage and a cold light source passage are arranged inside the endoscopic sheath. The hydraulic pressure flushing system comprises a connecting sleeve, a water inlet pipe, and a water outlet pipe. The holmium laser electric excision system for precisely treating sinus tract has the advantages that unhealthy scar tissues on the wall of the sinus tract can be precisely cut under direct vision, and the healthy tissues surrounding the sinus tract are protected to an utmost extent while precise treatment is carried out to the sinus tract, and precise, minimally invasive treatment on the sinus tract is truly achieved; and the holmium laser electric excision system is simple to operate and easy to learn, and is advantageous for wide clinical promotion by performing a magnified visible operation by means of the endoscope, thereby benefiting the masses.

Description

technical field

[0001] The invention relates to the technical field of medical devices, in particular to a holmium laser resection system for precise treatment of sinuses. Background technique

[0002] Sinus is an abnormal channel with the body surface caused by foreign bodies or tissue infection, necrosis, etc. The channel is often straight, curved and branched. Due to continuous chronic tissue infection and poor pus secretion, the surrounding soft tissue causes stress response, fibrous scar hyperplasia on the sinus wall, the surrounding skin tissue often erodes, and the wound does not heal. The migration of the patient's condition can further lead to changes in the spirit and psychology, indirectly lead to autonomic dysfunction, and cause changes in the hypothalamus-pituitary-gland function, resulting in insomnia, anxiety, depression and other psychoneurological symptoms.

[0003] At present, there is no particularly good method and measure for sinus in medicine. The tra...
