Embodiment Construction

[0047] exist figure 1 Among them, the electronic endoscope system 2 includes an electronic endoscope 10 and a self-propelled guide assembly 11 . The endoscope 10 includes a steering device 12 and an elongated tube 13 or catheter extending from the steering device 12 for access into a body cavity, such as the large intestine of the gastrointestinal tract. A universal cable 14 is connected to the handling device 12 . A connector or plug is provided at the end of the universal cable 14 for connection with a light source device (not shown) and a processing device (not shown).

[0048] The handling device 12 includes a steering wheel 15 for bending, an air / water button 16 and a suction button 17 . The air / water button 16 is operable to supply air or water through the distal end of the elongated tube 13 . An instrument channel 18 is formed in the elongated tube 13 of the manipulation device 12 for accommodating the access of medical instruments, such as electrosurgical instrument...

Abstract

A self-propelled type of guide assembly for an endoscope includes a barrel for receiving an elongated tube of the endoscope in an axial direction. A rubber ring retains the barrel to the elongated tube in a form with a clearance space defined between the barrel and the elongated tube. The barrel includes a barrel sleeve, having a first inner diameter according to an outer diameter of the elongated tube. An end cup is formed to extend from an end of the barrel sleeve, has a second inner diameter larger than the first inner diameter, for allowing the steering device in the elongated tube to steer. Furthermore, a movable endless track device has an annular surface, movable on an endless track outside the barrel, for pushing a wall of a body cavity for propulsion in the axial direction. A drive roller moves the endless track device relative to the barrel.

Description

technical field [0001] The present invention relates to a guide assembly for an endoscope. More particularly, the present invention relates to a guide assembly that enables smooth entry of an endoscope into a body cavity and keeps a steering device in the endoscope easy to steer. Background technique [0002] Endoscopes are used to diagnose body cavities, such as the large intestine in the gastrointestinal tract. Endoscopic control is a difficult procedure because the large intestine is a tortuous organ in the human body, and some body parts are very susceptible to changes in locations within the body such as the sigmoid colon and transverse colon. Learning to operate an endoscope for the large intestine takes a lot of experience and time. If the doctor's technique is not sufficient to perform the operation, the physical load on the patient's body will be very high. In view of this problem, JP-A 2003-339631 discloses a guide assembly for facilitating the entry of an endos...
