The surgery acupotomy has the beneficial effects of simple structure and high success rate.

Description

The special-purpose operation needle knife of a kind of de Quervain's disease

Technical field

This utility model relates to medical instruments field, relates in particular to the special-purpose operation needle knife of a kind of de Quervain's disease.

Background technology

De Quervain's disease is a clinical common diseases; Mainly be because the repeated friction of wound or tendon; Cause that the stndon sheath internal layer oozes out, hypertrophy, severe patient fiber adhesion, even form fibrous cartilage, become a fibrocartilaginous ring that band shape is narrow; Influence the normal activity of tendon, very the disease that can not in narrow stndon sheath, slide of person's tendon.Traditional treatment mainly is open surgery or adopts flat pin shovel percutaneous to cut the flat pin shovel of narrow employings such as stndon sheath and perform an operation; Hand function is affranchised; Operation process is long; The incidence rate of open operative complication is high, as: limited, the nerve injury of counting on one's fingers, cicatrix tenderness, infection of incisional wound or delayed union etc.The patient causes very big misery.

The utility model content

This utility model provides novel operation needle knife to the above-mentioned deficiency that prior art exists, and the point of a knife downside of pin cutter is the circular arc of blunt shape; The point of a knife needle body adopts curved shape, is provided with the blade perpendicular to knife bar near syringe needle one side simultaneously, and blade front side, rear side are provided with blade; Can realize two-way cutting movement when performing an operation, with the stndon sheath strip off, the unique design of point of a knife; Can realize getting into stndon sheath fast, practice thrift the time of operation, improve success rate of operation again.

The purpose of this utility model is to realize through following technical scheme:

The special-purpose operation needle knife of a kind of de Quervain's disease; Comprise handle, knife bar, said knife bar rear end is provided with handle, and said knife bar front end is provided with point of a knife; Said point of a knife downside is the circular arc of blunt shape; Said knife bar middle bent forms bending section, and said knife bar is provided with the blade perpendicular to knife bar near point of a knife one side.

Said blade is triangular in shape, and the forward and backward both sides of said blade are respectively equipped with front side blade and rear side blade.

Said rear side blade is linear or inside spill perpendicular to knife bar.

This utility model beneficial effect: simple in structure, success rate is high.

The specific embodiment

According to accompanying drawing and embodiment this utility model is done further explain below.

As shown in Figure 1, the special-purpose operation needle knife of the de Quervain's disease of this utility model is made simply, at first uses steel wire; Install handle 1 in the rear end, the middle part is converted into curved shape or circular-arc, and the angle of bending section 8 is generally 150 degree, its role is to make the knife bar 2 of pin cutter can be in the skin surface perk; Convenient operation, 8 length is generally 6 centimetres from handle 1 to bending section, and the front end of steel wire is a point of a knife 3, and point of a knife downside 10 is the circular arc of blunt shape; Effect is that the circular arc of blunt shape can assist the sharp-pointed portion of point of a knife 3 to advance fast, is deep in the stndon sheath, and point of a knife 3 generally is 3 centimetres to the length of bending section 8, and the pin cutter of this structure can reduce resistance; Reach patient's disease sites fast, near point of a knife 3 one sides, vertically be provided with blade 4 at knife bar 2, blade 4 be shaped as triangle; The class side is preferably right angled triangle in the shape of fin, and all there is blade the both sides, front and back of blade 4 just two limits on triangular blade top, and front side blade 5 turns forward along knife bar 2 from the top of triangular blade 4; Cross with knife bar 2, with the angle of knife bar 2 be 45 degree, when its role is to stretch into stndon sheath, because inflammation is arranged; At this moment stndon sheath and tendon very closely can utilize the front side blade 5 of inclination and the sharp-pointed portion of point of a knife 3 and the circular arc entire combination of the blunt shape of downside to go deep into stndon sheath rapidly and accurately forward, non-slip with depart from, front side blade 5 can also be with the stndon sheath strip off simultaneously; Rear side blade 6 is a linear, in order to increase the effect of blade perpendicular to knife bar 2 vertically downward; Rear side blade 6 also can be designed as inside spill 7, is similar to the shape of reaping hook, its role is to the pin cutter when pulling back; Rectilinear edge or inflexed sickleshaped blade perpendicular to knife bar 2 remain the coupling part strip off with stndon sheath once more, realize once success of operation, need not to do reciprocal sexual act again; Practiced thrift operating time, especially front side blade 5 has been realized fast deeply and the stndon sheath of strip off for the first time, at knife bar 2 when pulling back; Rear side blade 6 has been realized the strong residue of flesh coupling part is all cast aside, and has practiced thrift the time of operation, has improved success rate of operation.

Operation is carried out at Ultrasonography.Field of operation skin strict sterilization.With ultrasonic probe with 75% ethanol repeatedly wiping sterilization be placed on the pars affecta skin surface; Utilize 75% ethanol as couplant; The movable finger of patient; Observe slip, the card pressure situation of tendon in stndon sheath, the major axis of will pop one's head in then places on the diseased region tendon longitudinal axis, in about 5 millimeters places, distally that metacarpophalangeal joints palmar, tendon harden as entry point.Anesthesia tailing edge flesh key y direction stings application on human skin, subcutaneous tissue at distal probe with point of a knife 3; Adjustment pin cutter and head angle are confirmed behind the position of tool tip point of a knife to be located to thrust stndon sheath on the edge of; Confirm that point of a knife pushes the front side blade 5 cut-away portions stndon sheaths that utilize pin cutter along the tendon surface to near-end with point of a knife after between tendon and the stndon sheath; After blade tip 3 reaches proximal edge with carrying on the pin cutter and pulling back to far-end; Utilize rear side blade 6 to cut stndon sheaths, make the most advanced and sophisticated whole process of blade be positioned at subcutaneous tissue, but will note making blade tip and skin to keep suitable distance in order to avoid incision skin.Extract the pin cutter, patient's active movement finger, ultrasonic observe tendon down and slide freely, do not have card and press after, finish operation.
