Description

Technical Field The present invention relates to a medical endoscope having a foreign body removing device,

The present invention relates to a medical endoscope provided with a foreign body removing device. More particularly, the present invention relates to an endoscope, and more particularly, to an endoscope having an injection nozzle for injecting fluid to clean a lens of a photographing device, thereby performing blood or foreign substances adhered to the lens during surgery or surgery, The present invention relates to a medical endoscope provided with a foreign body removing device which can greatly reduce a procedure and an operation time.

Generally, endoscopes are classified into medical endoscopes and industrial endoscopes according to their fields of use. Medical endoscopes are medical devices designed to directly observe and treat lesion sites in the body 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.

Such a conventional endoscope has a distal end, an insertion portion, and a head. The insertion portion is a portion to be inserted into the body or the inside of the device, and has a rear end connected to the head and a front end connected to the distal end. Such an endoscope is provided to capture the inside of the body or the inside of the device, and can be classified into a camera endoscope and an optical scan endoscope according to a photographing method.

For example, Korean Patent Registration No. 10-1670243 discloses a camera module mounted on a terminal for photographing a surrounding image and outputting the captured image as an electrical signal; End-side photoelectric conversion means mounted on the distal end for converting an electrical signal output from the camera module into an optical signal and outputting the optical signal; An optical transmission path used as a transmission path of the optical signal output from the distal-side transmission photoelectric conversion means, as a hole extending in the longitudinal direction of the insertion portion in the insertion portion located at the rear of the distal end; And a head-side photoelectric conversion unit mounted on a head located at the rear of the insertion unit and restoring an optical signal transmitted through the optical transmission line to an electrical signal and outputting the electrical signal.

Korean Patent Registration No. 10-1140875 discloses an image pickup apparatus including a lens barrel and an image pickup unit in which a contact pin having a contact pin mounted thereon is formed; An operation unit for operating an operation of the imaging unit; And a connection portion including a contact portion corresponding to the contact pin so as to connect the image sensing portion and the operation portion, the contact portion being in contact with the contact pin and electrically connected to the image sensing portion, wherein the image sensing portion further includes a connection substrate, An endoscope camera comprising a flexible substrate and a rigid substrate and including a contact fin portion extending to the rigid substrate is disclosed.

However, when the above-described prior art document is observed inside the body, blood or the like is adhered to a photographing apparatus located at the distal end of the endoscope, thereby obstructing the visual field, and thus it is difficult to observe precisely. It is necessary to repeat the operation of removing and reinserting the endoscope. Therefore, there is a problem in that it takes a long time for the operation using the endoscope as well as the burden on the patient when using the endoscope.

In addition, even if the lens of the photographing apparatus is cleaned and reinserted, the blood remaining in the vicinity of the treatment site is again buried, so that the efficiency of washing is inevitably lowered. If the endoscope is taken out during an important procedure during surgery It may be difficult to find the same point again, which may seriously affect the operation result.
