Description

Endoscope cap and endoscope device including same

The present invention relates to an endoscope cap and an endoscope device including the same, and more particularly, to an endoscope cap capable of effectively inhaling and removing surrounding noxious gases by inserting a tube for inhaling noxious gas into a cap fitted to the end of the endoscope, and including the same It relates to an endoscopic device.

An endoscope is a medical device that is inserted into an internal organ or body cavity to perform observation, biopsy, or other procedures in a minimally invasive way without the need for open surgery. There are various types of endoscopes depending on the area to be observed and used. In particular, the digestive endoscope is a light source lens that provides light to the distal end, a biopsy channel for performing biopsy or other procedures with the endoscope, and an image. It consists of a camera capable of receiving information, etc.

The forceps hole of the digestive endoscope is used when inflating the lumen during the procedure, sucking air, intestinal fluid, or excrement in the lumen, or performing procedures such as biopsy. there are problems with

For example, when an additional biopsy or procedure is required, a plurality of different types of endoscopic devices may be required at the same time. Accordingly, if a conventional digestive endoscope is used, the procedure becomes complicated and additional devices must be separately inserted and used, making the operation impossible or the operation time is lengthened due to poor efficiency.

In addition, when using an endoscopic device having one forceps hole, it is common for foreign substances to adhere to the inside of the forceps hole or to completely block the opening during the procedure, thereby preventing suction, and accordingly, the operation time may be prolonged, making smooth operation difficult. .

In order to solve some of these problems, Korean Patent Publication No. 10-1139574 discloses a separate suction passage to prevent the opening of the forceps hole from being blocked by the inner wall of the lumen forming the body organs when a substance is sucked through the forceps hole. It includes a passage forming portion for forming a. Here, the passage forming part has a curved surface on the surface of each of the plurality of passage protrusions so that the suction operation of the material such as air or serous fluid is performed smoothly, thereby preventing the opening of the forceps hole from being completely blocked by the inner wall of the lumen. have.

On the other hand, the endoscope device of this configuration is rather ineffective when a strong suction force is required. There is a limit in the user's ability to control the suction force of the forceps hole by primarily escaping the air along the passage forming part. That is, it is not suitable for a situation requiring strong suction during the procedure, so it may be uncomfortable to use.

In addition, the conventional endoscope has no choice but to perform an operation through a single forceps hole, and since the size of the forceps hole is limited, there is no choice but to use a surgical tool of a specific size, thereby reducing the effectiveness of the operation.

In addition, harmful gas is generated during electric cauterization among endoscope equipment, and it is necessary to remove it by suction. However, in the case of a conventional endoscope cap, when the end of the cap is in close contact with the organ tissue, only the noxious gas generated in the cap inner space can be sucked through the forceps hole, and the noxious gas existing in the external space around the cap is There are problems that cannot be eliminated.
