Description
Technical field
This utility model relates to one medically special measuring tool, and International Classification of Patents is A61B5/107, particularly relates to a kind of four limit skewed slot sliding pearl convergent-divergent medical science vernier.
Background technology
Medically, due to the needs diagnosed, treat or nurse, require the shape and size of the Measurement accuracy patient edge of a knife, wound, pressure ulcer, ecchymosis, scleroma etc. with it, but, current measurement, mostly be measurement respectively or the estimation measurement of carrying out all directions, such measurement is inaccurate, and easily makes wound infection pathogenic bacteria, therefore, how to address these problems, become people's problem demanding prompt solution.
Such as: radius far-end fracture is one of common fracture of upper limb, accounts for 15.7% of fracture of upper limb.Due to the importance of wrist joint function, its displacement degree reset recovery situation is subject to the attention of clinicist always.X-ray is the important means of diagnosis radius far-end fracture, and it is because of low price, easy to operately becomes the most conventional method.By means of x-ray, the judgement of radius far-end fracture displacement degree is decide to the selection of Therapeutic Method, whether the judgement for reduction of the fracture displacement situation can be understood the reduction of the fracture and be satisfied with.The indexs such as the past usual displacement degree according to radial articular surface, the palm inclination angle, radius height, simoid notch index judge the displacement degree of the fracture of fracture, measure relatively loaded down with trivial details.Wolfe proposes the concept of radius box, is used for judging that the carpal joint line of force changes.But all the time to the judge index of fracture often by direct-view or simply measure, not professional survey tool.The application that distal radius measures square chi can help doctor to quantize displacement fracture situation, line of force change, reset case, assists the formulation of medical scheme.
Chinese patent " a kind of medical survey vernier " (patent No.: 2014204316460) and " judge radius far-end fracture displacement degree survey vernier " (patent No.: 2014205442719), propose very practical measure respectively, but all cannot accomplish to allow four ruler places, limit at grade, therefore, easily error on line of sight is produced.
