Abstract

The utility model discloses a kind of needle knives for treating stenosing tendon synovitis of flexor, including syringe needle, needle body and needle handle, it is characterised in that：Syringe needle, needle body and needle handle are an integral molding structure, and it is 35 40 ° to have V-arrangement end, v-shaped opening angle γ on syringe needle；When operation, finger flexor tendon ring-type fibrous sheaths of fingers proximal end, V-arrangement end is smoothly pierced into the cyclic annular fibrous sheaths of fingers proximal end at the deep fascia of fingers and palms side, it is located in V-shaped part, V-arrangement end is elapsed to cyclic annular fibrous sheaths of fingers tail end along stndon sheath direction of travel, goes out knife, art, which finishes, sticks wound；The utility model is safe and reliable, reduces degree of tissue damage, reduces the stripping number in stenosing tendon synovitis of flexor, and v-shaped opening angle γ, which is 35 40 ° of benefit, is：When V-arrangement head end is pierced into deep fascia, ring-type can be referred to fiber stndon sheath layer and blocked, cannot include flexor tendon, when elapsing needle knife forward, easy damaged flexor tendon itself, does not increase the safety of needle knife treatment.

Description

A kind of needle knife for treating stenosing tendon synovitis of flexor

Technical field

The utility model is related to a kind of medical instrument, more particularly to a kind of needle for treating stenosing tendon synovitis of flexor Knife.

Background technology

Since people are in using mobile phone, mouse and routine work, housework, the strain of finger is not paid attention to, lacks fortune in addition Dynamic and maintenance, causes the generation of stenosing tendon synovitis of flexor more and more, age of onset tends to become younger.The prior art is more It is to be treated by needle knife, needle knife technology is that minimal invasion is loosened the therapy of stenosing tendon synovitis of flexor, is mostly used 4# flat mouth needle-knife solutions need to remove completion that long and narrow cyclic annular fibrous sheaths of fingers could be loosened for several times, increase wound, and wound holds Easily there is swelling, pain, some patients are treated using cutting operation, and this treatment wound is larger, and patient is generally difficult to receive, and has When there is also wound infection, damage refer to nerve, finger necrosis risk.

Invention content

It is by needle knife utility model aims to solve above-mentioned existing stenosing tendon synovitis of flexor treatment is mostly It is treated, needle knife technology is that minimal invasion is loosened the therapy of stenosing tendon synovitis of flexor, is mostly used 4# flat mouth needle knives It loosens, needs to remove the completion that long and narrow cyclic annular fibrous sheaths of fingers could be loosened for several times, increase wound, wound is susceptible to swollen Swollen, pain, some patients using cutting operation treat, this treatment wound is larger, and patient is generally difficult to receive, sometimes there is also Wound infection, damage refer to neural, finger necrosis risk etc., and provide a kind of needle for treating stenosing tendon synovitis of flexor Knife.

The utility model includes syringe needle, needle body and needle handle, it is characterised in that：Syringe needle, needle body and needle handle are integrally formed knot Structure has inclined-plane on syringe needle, and the angle that inclined-plane is formed with needle body is 30 °, and there is V-arrangement end, v-shaped opening angle γ to be on syringe needle 35-40°；

The long 40mm of needle body, the long 5mm in V-arrangement end, the long 20mm of L-shaped tail end of needle body, the long 10mm of needle handle；

The L-shaped angle α of needle body is 60-80 °, and the angle β between needle body and needle handle is 50-70 °.

The operation principle and process of the utility model：

When operation, by hand thorough disinfection, palm lies against disposition platform, the covering of hole towel upwards, and finger flexor tendon ring-type refers to Fibrous sheath proximal end, does local infiltration anesthesia, and V-arrangement end is smoothly pierced into the cyclic annular fibrous sheaths of fingers proximal end at the deep fascia of fingers and palms side, makes It is located in V-shaped part, elapses V-arrangement end to cyclic annular fibrous sheaths of fingers tail end along stndon sheath direction of travel, goes out knife, flexor tendon is examined to live Dynamic range, art, which finishes, sticks wound, and V shape opening angles γ, which is 35-40 ° of benefit, is：It, can be ring when V-arrangement head end is pierced into deep fascia Shape, which refers to fiber stndon sheath layer, to be blocked, and cannot include flexor tendon, and when elapsing needle knife forward, easy damaged flexor tendon itself, does not increase The safety for having added needle knife to treat.

The beneficial effects of the utility model：

The utility model has the advantages of simple structure, easy to operate, securely and reliably, reduces degree of tissue damage, reduces flexor tendon Stripping number in de Quervain's disease, mitigate local swelling, pain symptom, wound is smaller, and patient can receive, and avoids hindering Mouthfeel dye reduces the risk that damage refers to nerve and finger necrosis.

Fig. 2 is the close-up schematic view at the utility model A.

Specific implementation mode

Please refer to Fig.1 with shown in Fig. 2, including syringe needle 1, needle body 2 and needle handle 3, it is characterised in that：Syringe needle 1, needle body 2 and needle Handle 3 is an integral molding structure, and has inclined-plane 11 on syringe needle 1, and the angle that inclined-plane 11 is formed with needle body 2 is 30 °, has V on syringe needle 1 Shape end 12, v-shaped opening angle γ are 35-40 °；

2 long 40mm of needle body, 12 long 5mm of V-arrangement end, needle body 2L shapes tail end 21 long 20mm, 3 long 10mm of needle handle；

Needle body 2L shape angle αs are 60-80 °, and the angle β between needle body 2 and needle handle 3 is 50-70 °.

The operation principle and process of the utility model：

It please referring to Fig.1 with shown in Fig. 2, when operation, by hand thorough disinfection, palm lies against disposition platform upwards, the covering of hole towel, Local infiltration anesthesia is done in finger flexor tendon ring-type fibrous sheaths of fingers proximal end, and V-arrangement end 12, which is blurted out, to be pierced at the deep fascia of fingers and palms side Cyclic annular fibrous sheaths of fingers proximal end, is located in V-shaped part, along stndon sheath direction of travel passage V-arrangement end 12 to cyclic annular fibrous sheaths of fingers tail End goes out knife, examines flexor tendon scope of activities, and art, which finishes, sticks wound, and v-shaped opening angle γ, which is 35-40 ° of benefit, is：V-arrangement head When terminal spine enters deep fascia, ring-type can be referred to fiber stndon sheath layer and blocked, cannot include flexor tendon, when elapsing needle knife forward, no Easy damaged flexor tendon itself increases the safety of needle knife treatment.
