Description

Palm phalanges external fixation traction frame

This utility model relates to a kind of palm phalanges fixed traction device, specifically a kind of palm phalanges external fixation traction frame, be applicable to behind hand 2-5 metacarpal bone, phalanges (joint near) closure stable fracture, the unstable fracture operative reduction and need change dressings for a long time patient's fixed traction of open fracture, also be suitable for the reset fixed traction of the patient after back and the hand flexor tendon injury repairing of 2-5 metacarpophalangeal joints, dislocation of interphalangeal joint of hand.

At present, the Therapeutic Method of using always for metacarpal bone, Phalangeal fracture is: traditional method is the plaster fixation frame, and this fixed mount is very heavy, can not under direct-view, observe the fracture end fixed effect, and be unfavorable for local wound replacing spice, and also influencing normal articulations digitorum manus motion, ankylosis appears; Another is open reduction, internal fixation therapy, and the shortcoming of this Therapeutic Method is that wound is big, complication is many, and need when taking out inside-fixture to need second operation; Also has a kind of miniature multi-function fixed mount, this fixed mount in use, need be at fracture site with bolt or draw point internal fixation, operation technique is complicated, operating technology requires high, the probability of damage injury blood vessel, nerve and tendon is arranged, and make fracture site periosteum sclerotin be subjected to secondary damage, in addition, this fixed mount price is also higher.Above various methodologies does not all have the effect of direct skin traction.

The purpose of this utility model be to provide low, the easy operation of a kind of cost of manufacture, flexibly light, change dressings and wound surface observe convenient, do not need second operation and other damages, be exclusively used in the palm phalanges external fixation traction frame of palm, phalanges.

This utility model is achieved in that this palm phalanges external fixation traction frame is made of damage location fixed mount and standing part, jib before the bottom of fixed mount is provided with so that whole be fixed on the arm, traction frame is established on top, preceding jib, the damage location fixed mount, traction frame is connected to an integral body, the damage location fixed mount, preceding jib, traction frame can be with 8-10 number, the iron wire of long 50-70CM is made in aggregates, the damage location fixed mount is consistent with back of the body bent angle A and patient's carpal joint dorsiflex position bent angle of preceding jib binding site, inside corners B is consistent with the metacarpophalangeal joints bent angle at damage location fixed mount middle part, and the damage location fixed mount is consistent with traction frame connecting portion inside corners C and interphalangeal joint angle of bend.The binding site back of the body bent angle A of damage location fixed mount and preceding jib is the 10-40 degree, and damage location fixed mount middle part inside corners B is the 60-90 degree, and damage location fixed mount and traction frame connecting portion inside corners are the 10-20 degree; Preceding jib, damage location fixed mount, traction frame are two iron wires, before crack distance between two strands of the jibs adapt with the hands forearm, length is 13-17CM, the centre is provided with the willfully Gu Gang of 2-3 root band certain radian, crack distance between two strands of the damage location fixed mounts is slightly less than finger width, crack distance between two strands of the traction frame is less than finger width, length is for surpassing the 2-4CM of damage finger end, rubber band one end is fixed on the top of traction frame, one end is connected finger skin traction position, with rubber band tractive finger; Each angle of bend A, B of this palm phalanges external fixation traction frame, C all can look the reduction of the fracture and require and adjust flexibility under x-ray fluoroscopy.

Application process of the present utility model is: fracture end, joint dislocation and refer to the flexor tendon reduction after, this is placed in palm or the back of the hand Side, preceding jib is fastened on the hands forearm with binder, finger far away is scratched the chi both sides with the rubberized fabric adhere of a long 6CM, wide 1CM in finger, far-end stays the 0.5CM gap, puts on rubber band, makes it to be fixed in the traction frame far-end, and being pulled to suitable tension force, the reuse adhesive plaster twines one week of interphalangeal joint far away.Palm, finger section are looked traumatic condition and are got final product with binder is fixing.In the time of fixedly, make finger longitudinal axis subtend navicular bone tuberosity.The palm refers to, interphalangeal joint and flexor tendon injury of finger person, and no tension force is fixed the back dismountings of three weeks; Palm or phalanx bone fracture needs 4-6 to remove after week.

The utility model has the advantages that: compare with the method for present use, overcome the shortcoming of local soft tissue, sclerotin injury and the second operation taking-up inside-fixture of performing the operation internal fixation and increasing.And this is in light weight, comfortable, easy to operate, integrate fixed traction, the flexibility that can under x-ray fluoroscopy, look reduction of the fracture requirement adjustment rack, and can under the situation of not taking external fixer apart, carry out wound and change dressings, observe the hands blood fortune situation of hindering.Do not fix normal palm, finger, avoided complication such as unnecessary ankylosis.

Below in conjunction with accompanying drawing this utility model is described in further detail.
