Abstract

The present invention relates to an injector instrument for an endoscopic operation, which can comprise: a coagulator for cauterizing a lesioned portion by a cautery electrode connectable to a high frequency generator for supplying high-frequency power; an injector for injecting a liquid medicine into the lesioned portion by a needle connectable to a syringe for supplying the liquid medicine; and a link connector for connecting the coagulator and the injector such that the needle can pass through the cautery electrode and be inserted thereinto and withdrawn therefrom. Accordingly, a treatment process of injecting the liquid medicine into the lesioned portion or cauterizing the lesioned portion so as to remove and coagulate the same while observing the lesioned portion through an endoscope can be carried out without switching instruments, thereby greatly shortening the time required for the endoscopic operation and improving the success rate of the endoscopic operation at the same time, and remarkably reducing the risk of the development of side effects.

Description

Endoscopic Injector Apparatus

The present invention relates to an injector device for endoscopy, and more particularly, to inject a drug solution into a lesion area while observing the lesion site through an endoscope, or to remove and coagulate the lesion site without performing a device replacement. To an endoscopy injector device.

An "endoscope" is a medical device designed to insert a machine into an internal organ or body cavity where the lesion cannot be seen directly without surgery or autopsy.

Endoscopy was first developed by Kussmaul in 1868 and was developed and clinically applied by vonMikulicz in 1881, and in 1932 Schindler developed and developed a flexible endoscope. Was applied.

Later, in 1960, a flexible optical endoscope was developed by Hirschowitz, which was able to directly identify internal organs and tissues even when the endoscope was bent with the development of optical fibers. The development of a video endoscope has allowed endoscopy to make histological diagnosis of organs and tissues inside the body.

Commonly used types include bronchoscope, esophagus, stomach, duodenum, rectal, bladder, laparoscopic, and other special ones include thoracoscopic, mediastinal, cardiac, and the like.

In addition, the endoscope includes a straight tube called a straight tube, which allows the human body to be directly seen by the naked eye, a lens system, a stomach camera that directly inserts a camera into the organ, and a fiber scope using glass fiber.

Recently, gastric camera and gas fiber scope are widely used for the early detection of gastric cancer, which can detect and diagnose microscopic gastric lesions by inserting a small camera into the stomach and directly recording and recording the mucous membrane of the stomach. The stomach fiber has good resolution and can be attached to a device that can cut and examine lesion tissue while observing the state of the mucosa.

Endoscopic Submucosal Sissection (EDS) or Endoscopic Mucosal Resection (EMR), Esophagogastroduodenoscopy, Colonoscopy, etc. Various kinds of treatment tools are used for the treatment instruments.

That is, a knife that is commonly used for mucosal ablation of a tissue by entering a treatment instrument into a body through a tube connected to a treatment body constituting the treatment instrument and inserted into a working channel provided in an endoscope, a mucotomy and the like. Coagulator used for hemostasis during bleeding, and needle and bleeding for drug injection needed to inject saline as a means to inflate tissue to provide ease of resection. Various types of treatment tools, such as injection of washer fluid, for ease of visual field security are used.

That is, in various procedures using the endoscope, the affected part of the patient is incised at least within 1 cm, and then the image of the affected part taken by the endoscope positioned at the treatment site by inserting a treatment tool together with the endoscope to look into the affected part through the skin incision. While using a video output device to check in real time, cauterize the affected area, use a cauterizer to bleed the affected bleeding, or form a chemical inlet to the distal end connected to the syringe injecting the chemical solution in the syringe connected to the chemical inlet A needle for injecting the injected drug solution into the affected part may be injected into the affected part using a injector formed at the distal end.

When using various treatment tools as described above, one treatment tool is inserted through a tool hole provided in the treatment body constituting the treatment equipment, one operation is performed, the inserted treatment tool is withdrawn, and then another treatment equipment is inserted. It is made in the form of performing the desired treatment.

In particular, depending on the patient's condition, the small particles and the injector are alternately used repeatedly.

In other words, in the case of colonoscopy, the patient's lesion is removed with a small cauterizer or the hemorrhage is not only bleeding, but also the injection of the medicine is performed in order to alleviate the pain and treat the patient. In addition, after removing the lesion from the affected part by removing the cauterizer from the affected part, and then injecting the injector into the affected part and injecting the chemical solution into the affected part, the inconvenience of using the cauterizer and the injector alternately is not only followed.
