Conchoscope for transsphenoidal pituitectomy

Abstract

The invention discloses a conchoscope for a transsphenoidal pituitectomy, which comprises a conchoscope body and an eye lens, wherein the conchoscope body comprises a protection tube, an image transmission system and an image adjusting knob; the image transmission system is arranged in the protection tube; the eye lens is arranged at the front end of the protection tube and connected with the image transmission system; the image adjusting knob is arranged at the rear part of the conchoscope body; a suction hole and a connecting port are formed in the protection tube; the suction hole is located above the eye lens; the connecting port is located near the image adjusting knob; a slim tube is arranged in the protection tube and near a tube wall; the slim tube is communicated with the suction hole and the connecting port; the connecting port is connected with an electric negative pressure suction device; and a suction control button is further arranged at the connecting port.Compared with the prior art, the conchoscope can timely clear away smoke and blood caused intraoperatively, ensures a good operation environment, allows an operator to be proficient operationally, ensures effective conduction of an operation, is reasonable in structural design, and safe and reliable in performance, and facilitates improving an operation effect.

Description

technical field [0001] The invention relates to a nasal cavity and belongs to the technical field of medical instruments. Background technique [0002] Pituitary tumors are common benign tumors in the brain. The incidence rate is second only to glioma and meningioma. Pituitary tumors are divided into functional and non-functional. Functional pituitary tumors can cause endocrine dysfunction in the early stage. With the growth of pituitary tumors, both types of pituitary tumors can cause headaches, vision loss, and visual field defects. In severe cases, they can erode the skull base and accumulate hypothalamus, causing a series of symptoms such as cerebrospinal fluid rhinorrhea, intracranial infection, and water and electrolyte disorders. or life-threatening. Traditional pituitary tumor resection requires craniotomy, but this surgical method is complex, traumatic, high-risk, and prone to complications. There is a "transsphenoidal pituitary tumor resection" in China. The oper...

Problems solved by technology

At present, the "transsphenoidal pituitary adenoma resection" is performed using a common nasal cavity. During the operation, bleeding and smoke caused by electrocautery and electrocoagulation cause poor peeping effect. Suction smoke and bleeding, but due to the narrow nasal cavity, when too many instruments are inserted, the already very narrow surgical field will be narrowed, which is not conducive to surgical operations, and due to cooperation reasons, the suction of smoke and bleeding is often not timely enough, which affects the operation The operation and process bring a lot of troubles to the surgeon and cannot satisfy the ideal surgical effect
