The using method of the needle knife of the embodiment has the same basic steps as the embodiment 1, and mainly differs from the step three in that:
step one, propulsion: as shown in fig. 5, the knife edge 21 of the knife body 2 extends out of the soft sleeve 3, and the knife edge 21 is pushed to a pain point set at the superficial fascia layer;
step two, depth pushing: the knife edge 21 is continuously pushed forward along the shallow fascia layer to a set pushing depth;
step three, sweeping and scattering actions: as shown in fig. 6, the positioning and fixing mechanism 4 is used to push the soft casing 3 forward, the knife edge 21 retracts into the soft casing 3 until the positioning half-slot 41 is blocked in the casing blocking slot 312 and the blocking protrusion 44 is blocked in the blocking blind hole 12, the positioning and fixing mechanism 4 is pressed, and the front end of the soft casing 3 is swept; the positioning and fixing mechanism 4 can make the soft sleeve on the needle knife be flexible and freely assembled and disassembled outside or inside the needle body, and has the function of being accurately positioned and fixed;
step four, remaining the tube: as shown in fig. 7, after the sweeping movement is continued for a set time, the positioning and fixing mechanism 4 is removed, the knife body 2 is withdrawn, and the soft cannula 3 is fixed and left at the lesion site.
Step five, discharging pipes: after a certain period of time according to the comfort level, the soft cannula 3 is removed. Patients need to be ordered during treatment: the local part of the needle is not wetted during the tube retention period, so that the infection is prevented; do not move violently; when there is an abnormal feeling on the local part, the patient will not be nervous, and most of them is caused by allergy of the adhesive tape of the fixed sleeve 31, and the doctor can use other types of objects for fixation, such as Bonddy hemostatic plaster; if the tube is moved to cause local stabbing pain and no doctor is nearby, the tube can be discharged automatically.
According to the needle knife and the use method thereof, the positioning half slot hole 41 and the clamping protrusion 44 are cooperatively clamped with the sleeve clamping groove 312 and the clamping blind hole 12 at the corresponding positions, the specification of the positioning and fixing mechanism 4 can be correspondingly selected according to the size of a focus, the clamping is accurate and stable, the technical effect of accurately and stably sweeping and burying the soft sleeve 3 into the focus is achieved during sweeping and scattering actions, and the quick and accurate medical effect is further achieved. The soft sleeve on the needle knife can be stretched and disassembled freely outside or inside the needle body through the positioning and fixing mechanisms with different structures, and can be positioned and fixed accurately. The soft sleeve has the advantages that the soft sleeve is provided with an accurate shielding protection knife edge, so that other tissues of a patient cannot be accidentally injured by the knife edge, the knife edge can be prevented from being damaged, and the service life of the soft sleeve is prolonged.
The needle knife and the use method thereof have wide application range of indications, and are detailed in example 1.
