Extraction and suction integrated percutaneous endoscope puncture biopsy instrument

Abstract

The invention discloses an extraction and suction integrated percutaneous endoscope puncture biopsy instrument which structurally comprises an extraction and suction device, a limit component, an outer tube, an outer tube handle, a syringe, a syringe handle and an inner core wire, the syringe is arranged into an inner cavity of the outer tube, the syringe comprises a needle tip section and a needle body section, the needle tip section penetrates the far end of the outer pipe, the needle body section penetrates the near end of the outer pipe and is connected with the syringe handle, the near end of the syringe handle is connected with the extraction and suction device, a limit component is rotatably connected with the near end of the outer tube handle, and a slider is arranged on the syringe handle and slidably connected with the limit component. The biopsy instrument can meet requirements of any ultrasound endoscope mediation of digestive tracts and tracheae and further can be used fora non-ultrasonic through the scope, deep puncture biopsy, liquid extraction and the like under direct vision are achieved, puncture operation is simplified to a great extent, and operation safety isimproved.

Description

technical field [0001] The invention relates to a device, in particular to a suction-integrated endoscopic puncture biopsy device. Background technique [0002] Endoscopic puncture technology is a minimally invasive diagnosis and treatment technology completed through endoscopic working channels. Although it belongs to advanced endoscopic technology, it has been developed maturely all over the world in the past 30 years. The technology is to obtain diagnostic specimens of cells, tissues, and fluids through puncture, and can also perform puncture and aspiration therapy, and can also achieve the purpose of injection therapy. The endoscopes currently used for puncture generally include ultrasound endoscope and non-ultrasound endoscope (i.e. ordinary endoscope) puncture, among which, according to the difference in the application and design of different organs, it specifically involves transtracheal puncture, transtracheal puncture, etc. Ultrasonic endoscopic puncture, transdig...

Problems solved by technology

[0003] The common feature of the existing biopsy needle products is that the puncture depth cannot be selected during the cutting operation, which greatly limits the application range of the biopsy needle products, especially the TBNA biopsy needle, the needle body has only one length of extension, making it There is no clinical choice, which makes it impossible to perform the operation, or the puncture is too deep and the operation fails
