Understanding the Basics of Endoscopic Surgery

Endoscopic surgery allows doctors to see and treat inside the body using small cuts. An endoscope, a flexible tube with a camera and light, is inserted through these cuts. The camera sends images to a screen and helps doctors guide the procedure.

Endoscopic surgery involves smaller cuts than traditional surgery. This results in less pain and faster recovery for patients. There is also less bleeding and a lower infection risk. Patients often go home the same day, reducing hospital costs and stress.

Minimally invasive techniques, like endoscopy, are very important today. They make surgeries safer and easier for patients. These methods reduce physical and emotional strain. They are especially beneficial for patients who cannot handle major surgery. This approach also allows doctors to perform complex procedures with more precision.

Endoscopic surgery is used in many medical areas. Doctors use it to examine the stomach, intestines, and lungs. It is also used in joint and spine surgeries. This versatility makes endoscopy a valuable tool for diagnosing and treating many conditions.

Bending Sections Assembly

The bending section assembly is near the endoscope tip. It consists of articulated segments that can bend and flex, allowing the endoscope to navigate through tight and curved areas within the body. This flexibility is important for reaching difficult-to-access regions.

Bending Rubber

The bending rubber covers the bending sections, protecting the internal wires and ensuring smooth movement. It prevents friction damage and external factors. Maintain bending mechanism integrity.

Angulation Wire

The angulation wire runs through the bending sections and is connected to control knobs at the endoscope’s handle. Manipulating these knobs allows the doctor to control the direction and angle of the endoscope’s tip. Provide precise maneuverability during procedures.

Structure of the Bending Sections Assembly

The bending section assembly is a key part of an endoscope. Allow it to maneuver through the body’s complex internal pathways. Here’s a detailed look at its components.

Bending Sections

Bending sections are small, flexible segments located at the tip of the endoscope. These segments bend and move in multiple directions, which is important for navigating tight and curved areas inside the body. Each segment’s independent movement helps the endoscope reach difficult spots during medical procedures.
