Three-kit puncture needle for treating prosopalgia

Abstract

The invention discloses a three-kit puncture needle for treating prosopalgia. The three-kit puncture needle comprises a threading sheath, a threading needle and a probe, wherein the threading sheath is provided with a puncture channel; the threading needle is configured to be capable of penetrating through the puncture channel; a needle tip is arranged at the front end of the threading needle; thethreading needle is longer than the threading sheath; the probe is configured to be capable of penetrating through the puncture channel; a blunt head is arranged at the front end of the probe; and the probe is longer than the threading sheath. The puncture needle comprises the probe; the probe is longer than the threading sheath; the blunt head is arranged at the front end of the probe; the puncture needle can penetrate into an oval foramen for exploration and does not injure tissues in the oval foramen easily; during an operation for treating the prosopalgia, after the puncture needle pierces human skin, the threading needle is withdrawn; the threading sheath is retained in a human body; the probe is inserted from the threading sheath for detecting a situation in the oval foramen; and the puncture needle facilitates guiding a balloon catheter to enter, can also pierce an internal barrier membrane, facilitates entry of the balloon catheter to achieve smooth imaging, and improves an operation effect.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a three-set puncture needle for treating trigeminal neuralgia. Background technique [0002] The puncture needle for treating trigeminal neuralgia generally includes a needle and a needle sheath. After the puncture is used to puncture the skin of a human body, the needle is withdrawn, and the needle sheath remains in the human body for inserting a balloon catheter. The traditional method is to insert the balloon catheter directly after the needle is withdrawn, but because the needle cannot be penetrated too deep (for fear of damaging the internal tissue with a sharp needle), it cannot effectively detect and guide the balloon catheter, and the oval hole There is also a barrier membrane, and the softer balloon catheter is used to puncture the barrier membrane, which may change the position and direction of the balloon catheter and affect the subsequent contrast effect.

Problems solved by technology

The traditional method is to insert the balloon catheter directly after the needle is withdrawn, but because the needle cannot go too deep (for fear that the sharp needle will damage the internal tissue), it cannot effectively detect and guide the balloon catheter, and the oval hole There is also a layer of barrier membrane, and the softer balloon catheter is used to pierce the barrier membrane, which may cause changes in the position and direction of the balloon catheter and affect the subsequent imaging effect
