Description

Medical crochet hook

Technical field

This utility model relates to a kind of medical apparatus and instruments, particularly a kind of medical crochet hook.

Background technology

The flexor pollicis longus muscle tendon de Quervain's disease is that stndon sheath changes because of the chronic aseptic inflammation that mechanical friction causes, cause stndon sheath to thicken, tendon degeneration, distortion, clinical treatment is in early days with non-operative treatment: comprise braking, physical therapy, sealing, above-mentioned unsatisfactory curative effect is at this problem, we use a kind of medical crochet hook, adopt tendinous sheaths of flexor muscles of fingers to cut or the excision of part stndon sheath, and applying clinical is in the past few years treated flexor pollicis longus muscle tendon de Quervain's disease numerical example, satisfaction evident in efficacy.

Summary of the invention

Bad for the curative effect that solves the routine treatment for the treatment of the flexor pollicis longus muscle tendon de Quervain's disease at present clinically, adopt tendinous sheaths of flexor muscles of fingers incision or part stndon sheath that a kind of medical crochet hook for the treatment of the flexor pollicis longus muscle tendon de Quervain's disease and providing is provided.

This utility model is made up of pin handle, the needle body, syringe needle, pin handle, the needle body, syringe needle are formed in one, wherein the pin handle is a flat-shaped body, the section configuration of pin handle is a rectangle, the section configuration of the needle body is a circle, the needle body from pin begin to syringe needle only be gradual change from coarse to fine, syringe needle is a crotch, the outside of crotch is an arc, the inboard of crotch is a blade, the height of crotch inboard is 2.5 millimeters, and the positions at the 180 degree angles of relative one-tenth with syringe needle are provided with a sign at the back side of pin handle, and this medical crochet hook is that titanium alloy material is made.

The beneficial effects of the utility model are: simple in structure, easy to use, non-cracking fractures, and the little recovery of operation wound is fast.

The specific embodiment

See also Fig. 1, Fig. 2, Fig. 3, shown in Figure 4: this utility model is 1 by pin, the needle body 2, syringe needle 3 is formed, pin is 1, the needle body 2, syringe needle 3 is formed in one, wherein pin is 1 a flat-shaped body, pin is 1 section configuration one rectangle, the section configuration of the needle body 2 is a circle, the needle body 2 from pin 1 begin to syringe needle 3 only be gradual change from coarse to fine, syringe needle 3 is a crotch, the outside of crotch is an arc, the inboard of crotch is a blade, the height H of crotch inboard is 2.5 millimeters, becomes the positions at 180 degree angles to be provided with a sign at pin 1 the back side and syringe needle 3 are relative, and this medical crochet hook is that titanium alloy material is made.

Concrete case:

Male's 10 examples, women's 41 examples, age 35-60 year, 40 years old mean age.Diagnosis: flexor pollicis longus muscle tendon de Quervain's disease, the right hand see that 11 examples are the bilateral morbidity more.

Operation method: the nearly joint of patient's thumb refers to that the ventrimeson centre does local infiltration anesthesia, after coming into force, anesthesia utilize crochet hook to go into skin from the anesthesia pin hole, vertically enter and reach on the tendinous sheath of flexor pollicis longus, crochet hook upwards, utilize syringe needle 3 blunt nosed sliding to reach the coaster place along tendinous sheath of flexor pollicis longus, plump coaster can be laid one's hand on and increase to another hands of patient simultaneously at the immobilized patients thumb, advise the patient to bend thumb syringe needle 3 and reach and lay one's hand on and patient's thumb expands the place, i.e. coaster near-end, pin is 1 Rotate 180 degree, be that pin makes progress the sign at 1 back, this moment, syringe needle 3 pointed to coasters. and slightly firmly downwards, can thrust coaster and sever coaster, advise patient's flexing thumb along flexor pollicis longus muscle tendon traveling pulling crochet hook, snap disappears, perform the operation successfully, if still have snap to lay one's hand on and the snap place repeats to execute art, the aseptic wrapping of sterilizing, after fixing 24 hours, carry out active movement functional exercise.

Follow-up results: nothing recurrence evident in efficacy of above-mentioned case and tendon be fracture person again, and no injury of digital nerve is insensitive, surplus nothing recurrence in 1 year.
