Disposable veress needle manufacturing method and veress needle manufactured by same

Abstract

The invention discloses a disposable veress needle manufacturing method which comprises the following steps: 1) arranging a grip; 2) arranging a stylet; 3) arranging a puncture needle; 4) arranging a protector; and 5) arranging an acousto-optic warning device. The invention also discloses a veress needle manufactured by the disposable veress needle manufacturing method. The method disclosed by the invention is simple and easy to implement, and is low in cost. The veress needle disclosed by the invention has ingenious structural design: when the key is not pressed down, the protector starts the protection function to effectively protect the point of the puncture needle by utilizing a protection part on the stylet; in the puncture process, the protector stops protection, the acousto-optic warning device starts induction to correspondingly drive a buzzer and an LED (light-emitting diode) lamp, thereby warning the operator to concentrate; and after the pneumoperitoneum is punctured, the protector recovers the protection function to prevent the needle from accidentally injuring the internal organs, and meanwhile, the acousto-optic warning device is automatically shut down, thereby greatly enhancing the safety and effectiveness of the puncture surgery. The veress needle is simple to operate; and the veress needle is disposable, thereby avoiding cross infection and having high safety.

Description

technical field [0001] The invention relates to the technology in the field of medical devices, in particular to a manufacturing method of a disposable Veress needle and a Veress needle implementing the method. Background technique [0002] At present, laparoscopic minimally invasive surgery has become increasingly popular. It is reported that in gynecological surgery, 90% can be treated by laparoscopic surgery. Pneumoperitoneum is a commonly used step in laparoscopic surgery. Because the puncture for making pneumoperitoneum is "blind insertion", the large retroperitoneal blood vessels and the blood vessels of the abdominal wall, even the arteries, are hidden and cannot be directly seen or touched. Once injured, it often causes fatal massive bleeding; The risk of injury to the internal organs of the pelvis and abdominal cavity is also great. The existing Veress needle cannot judge whether the puncture is in place during the puncture process, only by the operator's feel. ...

AI Technical Summary

Problems solved by technology

Because the puncture for making pneumoperitoneum is "blind insertion", the large retroperitoneal blood vessels and the blood vessels of the abdominal wall, even the arteries, are hidden and cannot be directly seen or touched. Once injured, it often causes fatal massive bleeding; The risk of injury to the internal organs of the pelvis and abdominal cavity is also high

The existing Veress needle cannot judge whether the puncture is in place during the puncture process, only by the operator's hand feeling

After puncture into the abdominal cavity, the puncture needle is likely to damage internal organs due to the small elasticity of the needle core and no protective device.
