Endoscope with injection function

Abstract

The present invention relates to an endoscope and, more particularly, to an endoscope having an injection function on which a medicine-injecting injection needle is mounted so that medicine can be directly injected into a patient's affected part. The endoscope having an injection function includes an endoscope portion for in-body imaging; an injection unit that is provided with a syringe portion including a pharmaceutical unit where the injection needle is mounted and the medicine is loaded on an end portion and a medicine injection unit allowing the medicine to be injected to the affected part by applying pressure to the medicine in the pharmaceutical unit so that the medicine is injected into the affected part observed by the endoscope portion; and an endoscope pipe portion where the endoscope portion and the injection unit are integrally mounted. The medicine-injecting injection needle is directly mounted on the endoscope so that the injection of the medicine into the patient's affected part can become easier, more accurate, and more convenient. Also, the endoscope is manufactured to be openable so that exposure to the outside is minimized. In addition, the deterioration of the medicine injected through the injection needle and infection by outside germs is prevented from the beginning, and the medicine is allowed to reach a destination with ease by using the hydraulic pressure.

Description

technical field [0001] The present invention relates to an endoscope, and more specifically, to an endoscope with an injection function, which is equipped with a drug injection needle capable of directly injecting a drug into an affected part of a patient. Background technique [0002] In general, stone removal surgery may be performed as endoscopic surgery. At this time, since the papilla, which is the outlet of the bile duct, is narrowed, the stone cannot be discharged in this state. Therefore, the papillary sphincter is incised with the aid of a papillotome, the outlet of the bile duct is dilated, and the stone is removed. [0003] An example of such prior art is disclosed in Application No. 10-2005-0053433 "Treatment Tool and Treatment Method for Endoscope". [0004] The treatment tool for endoscope related to the first aspect of the prior art application number 10-2005-0053433 is a treatment tool for endoscope that is inserted and used through the endoscope, and has a...

Problems solved by technology

[0010] Moreover, in Japanese Laid-Open Patent Publication No. 2006-158840, in the injection action of directly injecting drugs into esophageal varices by using an endoscope with a built-in observation window and an injection needle catheter (catheter), since the injection needle catheter Inability to have an appropriate insertion angle to accurately insert esophageal varices, in order to solve the problem of penetrating esophageal varices, etc., an endoscope system is disclosed.

[0011] However, as mentioned above, for the prior art endoscope in which the observation window or the optical observation device are integrally formed, although the length from the syringe to the drug chamber is long, it does not have a structure to help the injection needle to be inserted into the affected part, nor does it There is a problem that it is difficult to inject the drug into the patient's affected part by having a configuration that enables the forced injection of the drug when the drug is injected into the affected part through the inserted injection needle
