Description

Technical Field

[0001] The invention relates to the field of medical instruments, and mainly to a multifunctional interface matched with an endoscope. Background Art

[0002] Endoscope is a commonly used medical device at this stage. Endoscopic technology involves entering the human body through natural channels or small incisions, and using external imaging of the device for examination and surgical treatment of human organs or tissues. In recent years, endoscopes have been widely used in clinical diagnosis and treatment, especially in minimally invasive surgery, which has made rapid progress. Minimally invasive surgery refers to surgical treatment performed through tiny incisions through the channel of an endoscopic instrument. It is widely used in departments such as general surgery, obstetrics and gynecology, urology, thoracic surgery, and orthopedics.

[0003] The structure of an endoscope is complex and sophisticated, and is equipped with image sensors, optical lenses, light sources, mechanical devices, etc. Due to the tiny size of the leading end and the insertion end of the endoscope, the existing endoscope usually has only one surgical instrument access channel with a diameter of 1mm-2.6mm. Therefore, during endoscopic surgery, if the patient needs to be injected with various drugs such as anesthesia and hemostasis, the surgical instruments in the instrument channel need to be pulled out first, and then the drugs are injected. This operation method is too cumbersome and takes a lot of time, affecting the efficiency of the operation. Summary of the invention

[0004] The purpose of the present invention is to make up for the deficiencies of the prior art and to provide a multifunctional interface matched with an endoscope, which can directly inject various drugs such as anesthesia and hemostasis during endoscopic surgery. It is easy to operate and does not require the surgical auxiliary equipment in the instrument channel to be pulled out separately.

[0005] To achieve the above objectives, the present invention provides the following technical solutions: a multifunctional interface matching an endoscope, mainly comprising: an endoscope connection base, a sealing cover, an endoscope instrument channel, a check membrane, an injection channel, and an injection branch interface.

[0006] The endoscope connection base is a terminal for combined connection with an endoscope, and is made by injection molding of medical polymer materials, including silicone rubber, polyurethane or soft polyvinyl chloride. The endoscope interface is located in the middle of the endoscope connection base and is compatible with the endoscope port.

[0007] The sealing cover is arranged at the upper end of the endoscope connecting base and is used for sealing the endoscope instrument channel.

[0008] The endoscope instrument channel is located in the center of the endoscope connection base and is connected to the endoscope interface.

[0009] The opening of the injection channel is arranged on one side of the endoscope instrument channel, above the side of the endoscope connection base, and is communicated with the endoscope instrument channel.

[0010] The check membrane is arranged in the endoscope instrument channel and is located above the opening of the injection channel, so as to prevent the drug from flowing out of the endoscope instrument channel when the drug is injected.

[0011] The injection channel and the endoscope instrument channel form an angle of 0°-180°. Preferably, the injection channel and the endoscope instrument channel form an angle of 30°-75°.

[0012] The other opening of the injection channel is an injection branch interface, which can be 1-2 mm higher than the outside of the endoscope interface, or be flush with the outside of the endoscope interface, so that when injecting drugs, the drugs can smoothly enter the instrument channel to stop bleeding and anesthesia in time.

[0013] The injection branch interface is connected to the Luer injection interface through an extension tube; the opening of the extension tube is respectively adapted to the injection branch interface and the Luer injection interface, so as to ensure airtightness and timely replace the injection of the drug.

[0014] The Luer injection interface is a one-way interface, which can be closed with a sealing cover, or a catheter clamp can be added to the extension tube to control the switch of the Luer injection interface to prevent the injected drug from flowing back.

[0015] Preferably, a one-way valve may be installed on the outside of the Luer injection port to prevent backflow of the injected drug.

[0016] The beneficial effects of the present invention are as follows: 1. During endoscopic surgery, surgical instruments can be directly injected into the surgical site through the Luer injection interface without exiting the endoscopic instrument channel, thereby reducing the number of operating steps and improving surgical efficiency.

[0017] 2. A one-way valve is set at the Luer injection port to prevent blood from flowing back when injecting anesthetic or hemostatic drugs, which will affect the effect of the drugs; a check membrane is set in the instrument channel to prevent the injected drugs from flowing out through the instrument channel, achieving a flexible opening and closing effect.

[0022] The main components include: an endoscope connecting base 10, a sealing cover 12, an endoscope instrument channel 11, a check membrane 15, an injection channel 13, and an injection branch interface 14.

[0023] The endoscope connection base 10 is a terminal for combined connection with an endoscope, and is made by injection molding of medical polymer materials, including silicone rubber, polyurethane or soft polyvinyl chloride. The endoscope interface 16 is located in the middle of the endoscope connection base 10 and is adapted to the endoscope port.

[0024] The sealing cover 12 is disposed at the upper end of the endoscope connecting base 10 and is used to seal the endoscope instrument channel.

[0025] The endoscope instrument channel 11 passes through the center of the endoscope connection base 10 and is connected to the endoscope interface 16 .

[0026] The opening of the injection channel 13 is arranged on one side of the endoscope instrument channel 11, above the side of the endoscope connection base 10, and communicates with the endoscope instrument channel 11; The injection channel 13 forms an angle of 30°-75° with the endoscope instrument channel 10. Another opening of the injection channel 13 is an injection branch interface 14. The injection branch interface 14 can be 1-2 mm higher than the outer side of the endoscope interface 11, or be flush with the outer side of the endoscope interface 11, so that when injecting drugs, the drugs can smoothly enter the instrument channel to stop bleeding and anesthesia in time. The check film 15 is arranged in the endoscope instrument channel 10, and is located above the opening of the injection channel 13, so as to prevent the drug from flowing out of the endoscope instrument channel when the drug is injected.
