Description
Technical field
This utility model relates to medical instruments field, especially relates to a kind of can coupling with human body heel anatomic form feature best fit, utilizes hinge and medical energy converter principle farthest to recover the manual reduction auxiliary device of the calcaneus transverse diameter of broadening simultaneously.
Background technology
Fracture of calcaneus is orthopedics department one of common disease clinically, and high falling or traffic accident etc. all can damage calcaneus, and under vertical violence effect, posterior articular facet interacts with astragalus, causes calcaneus to compress, subside and pulverize.Its main manifestations is the broadening of calcaneus transverse diameter, and arch of foot changes and to cause foot deformity, affects people's walking function.
Fracture of calcaneus need to be recovered width of calcaneus clinically, corrects valgus calcaneus or Varus deformity, thereby correct the foot line of force, reduces and causes pain under external malleolus, movable unfavorable and Sural nerve compression symptom because of transverse diameter broadening.The free-hand reset of general normal employing or use apparatus and directly carry out rectification and recovery, however free-hand rectification often can not reach satisfied reset due to strength deficiency or soft tissue swelling, or the excessive secondary fracture that causes calcaneus of strength, the complication such as soft tissue injury.We utilize the flexible Bidirectional-squeezing power of hinge in design, can momentary reset, and operation strength can be controlled flexibly, can reduce loss and the damage to soft tissue of reset strength simultaneously.
As shown in Figure 1, existing fracture of calcaneus manual reduction device comprises two folder rods 12 and two block plates 13 that are separately fixed on described folder rod 12 and are oppositely arranged, described steel plate 13 is directly welded on do extruding fulcrum on described folder rod 12, on the surface of described steel plate 13, be enclosed with spongy layer 14, two folder rods 12 include head and afterbody, between the head of two folder rods 12, being bolted device 15 connects, afterbody is all set with polymer sleeve pipe 16, and described bolt connecting device 15 is vertical with folder rod 12.During operation, utilize the parallel adjustment two of bolt connecting device 15 of head with the spacing between folder rod 12, make to be clamped in outside in the below calcaneus of medial and lateral malleolus as two block plates 13 of extruding fulcrum, manually hold with a firm grip and press from both sides the afterbody of rod 12, two extruding fulcrum can produce huge radial pressure, this radial pressure directly acts on outside in calcaneus, makes the calcaneus of broadening recover normal.
Utilize this fracture of calcaneus manual reduction device can solve well the problem of calcaneus posterotransverse diameter broadening, but the raising along with the development of medical skill and people quality of life, people also improve the requirement of medical policy thereupon, free-hand reset or utilize simple resetting means can not meet needs of medical treatment, and lack quantitatively, data declaration qualitatively, make the process of promoting this equipment run into a lot of difficulties.Simultaneously in clinical practice, we also find many problems, for example: mode with bolts, the spacing between can only two action bars of parallel adjusting, the motility that action bars is adjusted is lower; Also have the face in outside in the relative calcaneus of existing fixing head to be designed to plane, can not fit well with outside in calcaneus, can affect the fixed effect of this device; In addition, when using this equipment, for the effect of the relation of calcaneus deformation and pressure in extrusion process, crushing failure at high speed and slowly extruding, whether can cause secondary fracture etc. to lack quantitatively, data explain qualitatively, and then can not carry out to these parameters the regulation and control of a qualitative, quantitative.
Therefore design a kind of simple in structure, flexible and convenient operation, maximum correct deformity, the reset auxiliary appliance that recovers heel anatomic form feature has good medical prospect.
