The present invention relates to an endoscope kit having functions of injection, clamping, and placing medical materials or medicines, and more particularly to an endoscope combined with a working instrument. After the endoscope is positioned, the working instrument of the endoscope kit can be directly used to process biological tissues.
With the continuous advancement of surgical methods, traditional open surgery has advanced to the current minimally invasive surgery, for example, arthroscopic surgery and laparoscopic surgery have widely adopted minimally invasive surgery methods. In minimally invasive surgery, a small incision is formed at the site where the internal organ or tissue is to be operated because of inserting and guiding a tubular catheter (such as a cannula and trocar), and one or more surgical instruments are introduced through a single tubular catheter to perform the surgery. Since only a few fine holes are formed for inserting the working instruments, minimally invasive surgery causes less injury to the patient, faster healing period and less damage.
Further, medical endoscopes and accessories thereof can enter the human body through various tubes for observation or as surgical equipment. It can be widely used in the human body's throat, stomach, intestines, gallbladder and other digestive systems and urinary systems. Further, the conventional endoscope inspection is performed through a lens installed at one end of a flexible tube or through a rigid tube. Different endoscopes are matched with different types of endoscope lenses; the tube of the endoscope enters the body, so that the light source enters in front of the tube and an observer can observe through the lens. Then the data from the endoscope is transmitted to the observer and related electronic equipment to help the doctor's diagnosis and treatment. In addition, common accessories, such as clamps, surgeons can use different clamps to grasp, peel, cut or repair internal organs or internal tissues according to surgical needs. However, the commonly used endoscopes do not have the function of injecting medicines; surgeons need to go through other steps to inject medicines. The operation steps are cumbersome and increase the operation time; therefore, it is extremely easy to produce surgical risks.
In view of this, the inventor has invested a lot of research, development and effort, making breakthroughs and innovations, hoping to solve the current shortcomings with novel technical methods, not only bringing better products to the society, but also promoting industrial development at the same time.
In view of the above needs, the main purpose of the present invention is to provide an endoscope kit having functions of injection, clamping, and placing medical materials or medicines. When the endoscope is positioned, it can be injected directly, and the internal organs or internal tissues can be grasped, peeled, cut or repaired. Furthermore, the wound produced is small, and no additional treatment is required after the operation thus shortening the recovery period.

In some embodiments, one end of the second branch is connected to the first branch; and another end of the second branch has an injection interface for injecting a medicine into the injection needle. Further, one end of the third branch is connected to the first branch, and another end of the third branch is connected to the first light source input end.
In some embodiments, the endoscope comprises a switching mechanism connected to a second output, and the switching mechanism is an optical fiber light collection structure, an image transmission switching mechanism or a power source required for an LED light source; and the switching mechanism includes a wireless transmission module or traditional wire transmission.
In some embodiments, the working instrument is a biopsy forceps, an electrocoagulation instrument, an ultrasonic scalpel, an electric cautery or a laser optical fiber instrument or a combination thereof.
In some embodiments, when the working instrument is the biopsy forceps, the operation part of the biopsy forceps has at least two clamping parts and a fixing part, the two clamping parts are connected with the fixing part, and the fixing part is connected with the rod portion.
In some embodiments, the output is connected to an output device, and the output device includes a communication device, a control device, and a display device. The communication device is coupled to the lens and is used for sending the images captured by the lens. Further, the control device is communicatively connected to the communication device to receive the images sent by the communication device, and send the images to the display device after processing. Furthermore, the display device is coupled to the control device to receive and show the images after processing; wherein the output is connected to the output device wirelessly, and the wireless connection includes Bluetooth, ZigBee, Wi-Fi or RF etc.
