Description
BACKGROUND OF THE
Endoscopes are largely classified into medical endoscopes and industrial endoscopes, depending on the field of use. A medical endoscope is a medical device designed to directly observe and treat a lesion site of an organ without surgery or autopsy. These medical endoscopes include bronchoscopy, esophagus, stomach, duodenal, rectal, cystoscopy, laparoscopic, and other special cases include thoracoscopic, mediastinal, and cardiac. An industrial endoscope is a device designed to observe the interior of the device without disassembling the device in various industrial fields.
Generally, at the distal end of the endoscope as described above, there are provided a camera for photographing a lesion site and an inside of the device, and illumination for irradiating a lesion site or the inside of the device. In the case of a medical endoscope, a hole-shaped channel is provided at the end, and a treatment instrument such as a forceps or a laser beam is passed through the channel.
In order for the lesion or the inside of the device to be accurately observed, the direction of the camera and the illumination must be variously changed. Therefore, a distal end of the endoscope is provided with a joint device capable of flexing freely in various directions.
An example of a joint device provided at the end of the endoscope is disclosed in Korean Patent No. 10-0867658. In the articulated joint disclosed in Korean registered patent, a bending plate and a bending member are alternately stacked. In addition, the bending plate and the bending member are provided with a plurality of wire holes for insertion of the adjusting wire, so that the bending plate and the bending member must be thick enough to process the wire holes.
However, if the members (bending plate and bending member) constituting the articulating device are thick, the inner diameter of the members must be reduced, and the parts (illumination line, power line, etc.) installed to pass through the center hole of the members There is a problem that the placement becomes difficult.
A technique capable of solving the above problems is disclosed in Korean Patent Laid-Open Publication No. 10-2013-0073637. In this Korean patent, a plurality of joint rings are connected to each other to form a joint device. Each of the plurality of articulated rings includes a joint ring body and a wire guide protrusion. The wire guide protrusion is bent to the inside of the joint ring body at a corner of the joint ring body. A wire guide hole . In the technique disclosed in Korean Unexamined Patent Publication (Kokai) No. 2005-344401, since the wire guide protrusion is bent inside the joint ring body, it is not necessary that the joint ring body has a thickness enough to process wire holes. Therefore, the member (joint ring) constituting the joint device in Korean Patent Laid-open Publication No. 2000-22755 can have a larger inner diameter than the members (the bending plate and the bending member) constituting the joint device in the Korean registered patent.
A joint protrusion having a joint connecting hole is also provided at the corner of the joint ring body of Korean Patent Laid-Open. When the rivets are fastened to the joint connecting holes in the state where the connecting protrusions of the neighboring joint ring bodies are overlapped, the joint ring bodies are connected.
However, when the members (joint rings) constituting the joint device are connected through rivets as described above, it is difficult to manufacture the joint device and the manufacturing cost is also high. The joint device provided at the end of the endoscope has an inner diameter of about several centimeters. To tighten the rivet by the operator in such a small joint device, much effort and labor costs must be applied to the fastening operation. In particular, an increase in the manufacturing cost of the articulating apparatus will be a serious obstacle to the commercialization of disposable endoscopes capable of eliminating the disinfection process.
Therefore, the present invention is intended to provide an endoscopic end joint device capable of easy manufacture and low manufacturing cost.
The present invention provides an endoscopic end joint apparatus in which ring-shaped first soft joints and second soft joints are alternately connected to each other. Here, a pair of one-side coupling pieces having a 180 degree separation angle is provided on one circular edge of the first soft joint body and the second soft joint body. A pair of opposite side coupling pieces having a separation angle of 90 degrees with respect to the pair of one side coupling pieces and a pair of opposite side coupling pieces having a 180 degree separation angle with respect to each other are formed on the circular rim on the opposite side of the first soft joint body and the second soft joint body And a pair of wire guide pieces bent inward are provided. In addition, male protrusions are provided on one side of the first soft joint and on the opposite side of the engagement piece, and on one side and the opposite side of the second soft joint, female protrusions Holes are provided.
Alternatively, male protrusions may be provided in any one of the pair of one-side engaging pieces and the opposite-side engaging pieces, and a female hole may be provided for inserting the male protrusions into the remaining one.
The male protrusion is provided so as to be inserted inward from the outside of the female hole. In addition, the outer surface of the male protrusion is provided in a curved shape. The projecting length of the male protrusion is smaller than the thickness of the engaging piece having the female hole.
According to the present invention, the joints constituting the endoscopic end arthroscopic device can be easily joined between the joints by simply grasping and releasing the joints which are not used any additional parts such as rivets. Therefore, according to the present invention, the manufacture of the endoscopic end joint apparatus is much simpler than the conventional art, and the manufacturing cost is also very low.
Further, according to the present invention, since the male protrusion is provided so as to be inserted inward from the outside of the female hole, there is no possibility that the jacket surrounding the endoscopic end arthroscopic device is damaged by the male protrusion.
Further, according to the present invention, since the outer surface of the male protrusion is formed as a curved surface, damage or wear of the members (jacket or wire) contacting the male protrusion can be minimized.
Further, according to the present invention, since the protruding length of the male protrusion is smaller than the thickness of the engaging piece having the female hole, the male protrusion is not in contact with the peripheral member (jacket or wire) at all.
