Endoscope equipment

Abstract

The invention discloses endoscope equipment. The endoscope equipment comprises an endoscope, lenses and a lens ring, wherein the lenses and the lens ring are arranged at the front end of the endoscope, the lens ring is a hollow ring, a hanging table is arranged in one end of the lens ring, the lenses are mounted at the hanging table in the lens ring, and the lenses are made into a series according to the curvature. For the endoscope equipment, the lenses with different radians are designed, so that the lenses can be replaced for observing different target ranges, meanwhile, an optical zooming imaging lens is designed, and thus different target view fields can be observed through adjusting the focal length.

Description

technical field [0001] The invention relates to the field of medical equipment and supplies, in particular to an endoscope device. Background technique [0002] In surgical treatment of diseases, it is necessary to accurately puncture the lesion and then establish a surgical channel, or perform drainage, arteriovenous puncture and other surgical operations, such as external ventricular drainage, ventriculoperitoneal shunt, closed chest drainage, gastrointestinal decompression , Brain tumor or cerebral hemorrhage surgery, spinal surgery, etc. These operations require precise puncture to reach the surgical site to ensure success. The existing puncture or insertion into the surgical channel is non-visual, sometimes causing unsuccessful or serious side damage. In order to avoid surgical failure due to wrong puncture direction, variable focus endoscopic equipment under the guidance of navigation or ultrasound is needed to assist the operator to observe the puncture direction, pos...

AI Technical Summary

Problems solved by technology

In addition, in the process of establishing the surgical channel, the damage around the channel is inevitable. The channel is usually established by rigid puncture and expansion from the outside to the inside, which easily leads to pressure injury and the internal channel space is small, and the entrance space is relatively small. It is a big problem, or the channel can be established by passive expansion and contraction, but it needs to be placed in the working sheath twice, and it is easy to cause secondary damage to the surrounding channel
