Omni-directional steering device for endoscope

Abstract

The invention discloses an omni-directional steering device for an endoscope. The omni-directional steering device comprises a main hose, wherein the main hose is a solid plastic hose; the top end of the main hose is sleeved with a lens barrel, and the lens barrel is used for fixing a lens of the endoscope; the tail end of the main hose is connected with an operating handle; three channels are formed in the main hose and are a first channel, a second channel and a third channel respectively; a steering mechanism is embedded in the first channel; a main component of the steering mechanism is a steel wire rope; a sleeve is tightly fixed at the top end of the steel wire rope and used for fixing the lens barrel; one section of a part, close to the operating handle, of the steel wire rope is sleeved with a spring; a hollow steel tube is tightly fixed on the periphery of the steel wire rope between the spring and the operating handle and used for fixing the operating handle; an illumination optical fiber is embedded in the second channel; the third channel is hollow and serves as an inlet channel of a medical device. The omni-directional steering device is stable and reliable to operate. According to actual demands, a doctor can lock the omni-directional steering device at certain angle in any direction of 360 degrees during operation of the handle.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of medical instruments, and in particular relates to an omnidirectional steering device for an endoscope. [0003] 【Background technique】 [0004] Most of the steering mechanisms used in current endoscopes are technologies typically represented by snake bones. The operating part is a knob. For example: gastroenteroscope has two knobs, the big knob is responsible for controlling the up and down angle, and the small knob is responsible for controlling the left and right angles. Both the large and small knobs have a lock. When the lock is adjusted to a certain angle, the angle can be locked At this position, it is convenient for doctors to diagnose and treat this part. [0005] Focusing on snake bone technology is currently the standard practice in the endoscopy industry. It has the following disadvantages: 1. Since the snake bone is used, the biggest reason is the volume required by its mechanism it...

AI Technical Summary

Problems solved by technology

It has the following disadvantages: 1. Since the snake bone is used, the biggest reason is the volume required by its mechanism itself, which directly leads to the limitation of the external dimensions of the endoscope. It is difficult to achieve a diameter of 3mm for the endoscope according to the current technology the following

2. Since snake bones are used, the most difficult lead wire problems, including the lead wire traction in the main hose and the reliability of the lead wire itself, cannot be overcome technically in the industry

3. There is also the cost of the snake bone mechanism itself. Due to its technology and materials, it causes a relatively high cost, and it is unlikely to be applied to a disposable endoscope.

If the mirror leaks or the welding is not firm, the steel wire fixing parts are easy to desolder and cause no angle, which is a common fault
