Problems solved by technology

There is no fixed connection structure between the existing puncture needle and the needle sheath. When puncturing, generally only force is applied to the rear of one of the parts to make the two go deep into the human body. The sheath will withdraw backward due to internal resistance, which will affect the use effect

Abstract

The invention discloses a puncture needle connecting structure for treating trigeminal neuralgia. The puncture needle connecting structure comprises a puncture needle sheath and a puncture needle, wherein a puncture channel is formed in the puncture needle sheath; a first connecting piece is arranged at the rear part of the puncture needle sheath; a clamping block which extends outwards is integrally arranged on the first connecting piece; the puncture needle can penetrate through the puncture channel; the length of the puncture needle is greater than that of the puncture needle sheath; the front end of the puncture needle is a needle point part; a second connecting piece which cooperates with and is fixed to the clamping block on the first connecting piece is arranged at the rear part ofthe puncture needle; and the puncture needle sheath is connected with and fixed to the puncture needle through the first connecting piece and the second connecting piece. When puncturing a human body,the puncture needle sheath and the puncture needle can be smoothly pressed in only through applying force to the rear end of either of the puncture needle sheath and the puncture needle, and the situation that the puncture needle or an outer sheath is retreated backwards can be avoided.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a connection structure of a puncture needle for treating trigeminal neuralgia. Background technique [0002] The puncture needle for the treatment of trigeminal neuralgia generally comprises a puncture needle and a needle sheath. When puncturing, the puncture needle is combined into the needle sheath to puncture human skin together. There is no fixed connection structure between the existing puncture needle and the needle sheath. When puncturing, generally only force is applied to the rear of one of the parts to make the two go deep into the human body. The sheath will withdraw backward due to internal resistance, affecting the use effect. Contents of the invention [0003] The purpose of the present invention is to at least solve one of the technical problems in the prior art, provide a puncture needle connection structure for treating trigeminal neuralgia, and prevent the need...
