Abstract
This utility model relates to a kind of pubic symphysis separate shape memory internal fixation, comprise blade plate and pubic symphysis hook, it is characterized in that: blade plate comprises symmetrical ala of ilium fixing head and pubic branch fixing head, ala of ilium fixing head is lobulated structure, have screw fixed hole above, edge is fluted, on pubic branch fixing head, encircles arm, pubic symphysis hook is arc shaped hook, and the blade plate of the left and right sides is connected by associating axle with pubic symphysis hook.The utility model has the advantages that the anatomic form that can maintain pubic symphysis, kept the effectively fixing of pubic symphysis, be conducive to the healing of pubic symphysis.
Description
Technical field
This utility model relates to medical instruments field, is specifically related to a kind of internal fixation device that is used for the treatment of pubic symphysis separation that memorial alloy is material of take.
Background technology
Pubic symphysis separation is type of impairment common in fracture of pelvis, account for 24% of fracture of pelvis, can occur separately, also can merge lower support rib folding, posterior ring pelvic damage etc. on pubis, pubic symphysis separating treatment is improper will directly affect pelvis biomechanics function and lower limb walking, cause deformity.To pubic symphysis, expectant treatment is taked in separation traditionally, as apply pelvis bag, pelvis suspention etc., patient not only will stand the misery of long-term bed, and easily there is the complication such as nonunion, malunion and long-term chronic pain in expectant treatment, after wound, Operation in early stage can significantly reduce above complication, and patient can early ambulation, obviously prognosis improves, but due to the special anatomical features of pelvis, up to the present, also there is no internal fixation device and the method for pubic symphysis separation both at home and abroad.
Marmem has the shape memory effect with temperature correlation, and while being placed in cold medium, lower hardness is easily moulding, when temperature raises, produces restoring force and resilience force, returns back to voluntarily original shape.Why marmem has distortion recovery capability, because the thermoelastic martensitic transformation that in deformation process, material internal occurs, in marmem, there are two kinds of phases: high-temperature-phase austenite phase, low-temperature phase martensitic phase, according to different heating power load-up conditions, marmem presents two kinds of performances.
Summary of the invention
The purpose of this utility model is exactly the defect existing for prior art, and a kind of pubic symphysis separate shape memory internal fixation definite, that be beneficial to patient's functional rehabilitation of fixing is provided.
The technical problem that this utility model solves realizes by the following technical solutions.
Pubic symphysis separate shape memory internal fixation, comprise blade plate and pubic symphysis hook, it is characterized in that: blade plate comprises symmetrical ala of ilium fixing head and pubic branch fixing head, ala of ilium fixing head is lobulated structure, have screw fixed hole above, edge is fluted, on pubic branch fixing head, encircles arm, pubic symphysis hook is arc shaped hook, and the blade plate of the left and right sides is connected by associating axle with pubic symphysis hook.
When the patient of pubic symphysis separation uses this inner fixer, pubic symphysis separate shape memory internal fixation is placed in to low temperature flow, after separated pubic symphysis resets, the pubic symphysis hook of blade plate is fixed on to pubic symphysis place, by screw fixed hole, ilium fixing head is fixed on ilium, encircle armlet and embrace pubic branch, normal saline rewarming, pubic symphysis separate shape memory internal fixation is replied to shape memory, pubic symphysis hook is subject to the restriction of ilium fixing head and pubic branch fixing head to have lasting cohesion stress to pubic symphysis, separated pubic symphysis is stable to anatomical position, kept the effectively fixing of pubic symphysis, be conducive to the healing of pubic symphysis.
The beneficial effects of the utility model are: simple in structure, easy to use, mechanical property is good, not only can effectively fix pubic symphysis, promote the healing of pubic symphysis, and use procedure are simple, and operating time is short, has good clinical result of use.
Accompanying drawing explanation
Fig. 1 is structure of the present utility model and using state schematic diagram.
In figure 1, ala of ilium fixing head; 2, screw fixed hole; 3, encircle arm; 4, associating axle; 5, groove; 6, pubic symphysis hook; 7, pubic branch fixing head.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is further described.
As shown in drawings
,pubic symphysis separate shape memory internal fixation, comprise blade plate and pubic symphysis hook 6, it is characterized in that: blade plate comprises symmetrical ala of ilium fixing head 1 and pubic branch fixing head 7, ala of ilium fixing head 1 is lobulated structure, have screw fixed hole 2 above, edge is fluted 5, encircles arm 3 on pubic branch fixing head 7, pubic symphysis hook 6 is arc shaped hook, and the blade plate of the left and right sides is connected by associating axle 4 with pubic symphysis hook 6.
This utility model in use, pubic symphysis separate shape memory internal fixation is placed in to low temperature flow, after separated pubic symphysis resets, the pubic symphysis hook 1 of blade plate is fixed on to pubic symphysis place, by screw fixed hole 2, ilium fixing head 1 is fixed on ilium, encircle arm 3 and encircle pubic branch, normal saline rewarming, pubic symphysis separate shape memory internal fixation is replied to shape memory, pubic symphysis hook 6 is subject to the restriction of ilium fixing head 1 and pubic branch fixing head 7 to have lasting cohesion stress to pubic symphysis, separated pubic symphysis is stable to anatomical position, kept the effectively fixing of pubic symphysis, be conducive to the healing of pubic symphysis.
