Abstract

This utility model discloses an improved needle knife, comprising a needle handle, a needle body, and a blade head connected in sequence. The blade head is formed by two U-shaped blades integrally connected in the same direction. The connecting wall between the two U-shaped blades is shorter than the non-connecting walls on both sides, forming a double-peaked wavy profile. A cutting edge is provided along the double-peaked wavy profile, with a blunt cutting edge. The double-peaked wavy blade head of this utility model has a large release area and a blunt cutting edge, which can expand the cutting area through sliding, minimizing damage to surrounding blood vessels and nerves, thereby reducing the number of incisions and achieving a good decompression effect.

Description

Improved needle knife

Technical Field

Background

The needle knife is a novel medical instrument with the characteristics of both needles and knives. It is shaped like a "needle", but the tip of the needle is a flat knife of only 0.8mm, which is called a small needle knife because of its small size. The needle-knife medicine is a combination of a needle for traditional Chinese medicine acupuncture and a knife for western medicine operation, combines two therapeutic effects, starts from the root, controls the state of an illness in time and recovers health, so that the problem which is difficult to solve in therapeutics is solved.

Needle knife therapy is a closed loosening technique intermediate between surgical and non-surgical therapies. The operation is characterized in that after local tissue anesthesia is carried out, a small needle knife is quickly penetrated into a lesion part, and the adhered lesion tissue is quickly peeled off by the operation methods of clinical torsion, picking, pushing, pulling and the like, so that the blockage is dredged, qi and blood are smooth, scars are scraped off, bone and meat are loosened, the spasm and pain are relieved, and the cure purpose is achieved. The therapy has the advantages of small wound, less pain, less cost, short time consumption, quick response and high cure rate.

The needle knife device at present mainly comprises a needle handle, a solid needle body and a knife head, and the knife head cutting edge of the traditional needle knife is wedge-shaped or V-shaped. The wedge-shaped cutter head has small loosening area, needs to make multi-point, up-and-down lifting cutting on one part, has more small cuts and poor decompression effect, has sharp cutting edges of the V-shaped cutter head, is not easy to make sliding cutting in a fascia compartment, and can cause secondary iatrogenic injury.

Disclosure of utility model

The improved needle knife provided by the utility model has the advantages that the knife head is in a double-peak wave shape, the loosening area is large, the cutting edge is round and blunt, the cutting area can be enlarged by sliding, and the damage to peripheral vascular nerves is small, so that the number of incisions is reduced, and the decompression effect is good.

In order to achieve the technical purpose, the utility model adopts the following technical scheme:

the utility model provides an improvement needle sword, includes needle handle, needle body, the tool bit that connects gradually, and the tool bit is formed by two syntropy U type tool bit body coupling, and the connecting wall in the middle of two U type tool bits is shorter than the non-connecting wall of both sides, forms the double-peak wave profile, is provided with the cutting edge along the double-peak wave profile, and the blade is round blunt.

Further, the cutter head is thick at the upper end and thin at the lower end, and smooth inclined planes gathered downwards are arranged at the two sides of the cutting edge.

Furthermore, the needle handle is thick at the upper and lower ends and thin at the middle, and concave cambered surfaces are arranged at the front and rear sides.

Furthermore, anti-skid patterns are uniformly distributed on the concave cambered surface.

Further, the non-connecting arms on both sides of the cutter head are slightly opened outwards.

Compared with the prior art, the utility model has the beneficial effects that:

1. the cutter head is in a double-peak wave shape, the loosening area is large, the cutting edge is round and blunt, the cutting area can be enlarged by sliding, and the damage to peripheral vascular nerves is small, so that the number of incisions is reduced, and the decompression effect is good;

2. the middle part of the needle handle is concave and provided with the anti-skid patterns, so that the hand grip is strong, and the hand grip is not easy to take off in operation.
