Abstract
The utility model relates to an outer leg fixing system for orthopedics department, which is directly wrapped at the positions of human legs and comprises a leg cavity sheet with an inner cavity and polyurethane arranged in the inner cavity of the leg cavity sheet, wherein the two side ends of the leg cavity sheet are connected together by a connecting device to form a jacket. As the outer leg fixing system with enough rigidity and intensity can penetrate through X-rays, a medical staff can clearly know the healing condition of fractured parts; meanwhile, the outer leg fixing system is convenient to ventilate and clean; moreover, the medical staff can easily take down the outer leg fixing system for cleaning and treating the skin surfaces of injured parts according to the need of a patient, so that humanized treatment is completely reflected.
Description
Technical field
This utility model relates to orthopaedics external fixation field, relates in particular to a kind of shank orthopaedics external fixation system.
Background technology
Existing Orthopeadic Surgery immobilization material and method mainly contain: plaster fixation, AGMA are fixed, prefabricated molds is fixed and inner support is fixed.
Plaster fixation adopts Gypsum Fibrosum as immobilization material, and its shortcoming is to be not suitable for handling complex region, is difficult to transmitted X-rays, and can not shirk etc., whole agglutination patient comparatively feels bad.
AGMA is fixing mainly to be applicable to the location, and being used for fracture and bone splits, to fix its effect not ideal enough.
The fixing patient of need of prefabricated molds repeatedly comes and goes hospital and revises the unfavorable popularization of wasting time and energy.
Can cause new bone wound and infection and inner support is fixing, cost is very high, reduces just day by day and uses.
At publication number is in the utility application of CN101906202A, " a kind of polyurethane for orthopedic external fixation system in complicated environment and preparation method thereof " by name, a kind of polyurethane that is used for the orthopaedics external fixation system is disclosed, this polyurethane is reacted by 1: 0.6～0.75 weight ratio by polyether polyol mixture and modified isocyanate and makes, this polyurethane cooperates die cavity to use, and can handle the reluctant complex region of plaster fixation and fix.
Therefore, the polyurethane orthopaedics external fixation system that is applicable to shank (comprising thigh and shank) is that those skilled in the art are devoted to one of direction of studying always.
Summary of the invention
The purpose of this utility model provides a kind of shank orthopaedics external fixation system exactly in order to address the above problem.
The purpose of this utility model is achieved in that a kind of shank orthopaedics external fixation system, comprise shank die cavity sheet with inner chamber and the polyurethane that places this shank die cavity sheet inner chamber, two sides of described shank die cavity sheet are joined together to form the sheath shape by connecting device, directly are wrapped in the shank place of human body.
Above-mentioned shank orthopaedics external fixation system, wherein, described connecting device is that slide fastener or tearing are buckled.
Above-mentioned shank orthopaedics external fixation system, wherein, described shank die cavity sheet is made by the flexible material that does not change the body surface potential difference and have a retractility.
Above-mentioned shank orthopaedics external fixation system, wherein, the described flexible material that does not change the body surface potential difference and have a retractility is pure cotton knitted fabric, cotton and corn fiber blending knitted fabric or cotton ramie blended spinning knitted fabric.
This utility model shank has enough rigidity, intensity with the orthopaedics external fixation system, again can transmitted X-rays, can clearly understand the situation of fracture site recovery from illness thus; Also be convenient to simultaneously breathe freely, clean, medical personnel can shirk to clean and to handle the skin surface of injury freely according to needs of patients, demonstrate fully the hommization treatment.The expense of patient's payment is fixing more much lower than the inner support of more use in recent years, and does not cause infection, than AGMA fixed effect ideal, than plaster fixation superior cost performance is arranged.
Description of drawings
Fig. 1 is the structural representation of this utility model shank with the orthopaedics external fixation system;
Fig. 2 is a schematic partial cross-sectional view among Fig. 1;
Fig. 3 is this utility model shank is wrapped in the human body shank with the orthopaedics external fixation system a sketch map.
The specific embodiment
Participate in Fig. 1 to Fig. 3, this utility model shank comprises the shank die cavity sheet 11 with inner chamber and places this shank die cavity sheet 11 inner chamber polyurethane 12 with the orthopaedics external fixation system, two sides of this shank die cavity sheet 11 are joined together to form the sheath shape by connecting device 13, directly be wrapped in the shank of human body, this connecting device 13 is a slide fastener, it also can be tearing button (not drawing among the figure), polyurethane 12 is mixed by 1: 0.6～0.75 mass ratio by polyether polyol mixture and modified isocyanate, the quality of described polyurethane 12 is 580～1100 grams, size according to the human bodily form, large size need restrain polyurethane with 930～1100, medium size need restrain polyurethane, the small size need with 580～710 gram polyurethane with 740～920.Wherein, shank die cavity sheet 11 is made by the flexible material that does not change the body surface potential difference and have a retractility, as the knitted fabric (as cotton 70%, corn fiber 30%) of pure cotton knitted fabric or cotton and the multiple ratio blending of corn fiber or the linen-cotton knitted fabric of cotton and numb multiple ratio blending (as cotton 70%, numb 30%), this material retractility can reach 15%.
Polyether polyol mixture and modified isocyanate are mixed by 1: 0.6～0.75 mass ratio, make polyurethane slurry after stirring, size according to people's bodily form, large size need restrain polyurethane slurries with 930～1100, medium size need restrain polyurethane slurries with 740～920, the small size need with 580～710 gram polyurethane slurries, after the polyurethane slurry of appropriate amount being poured in the inner chamber of shank die cavity sheet, use specific purpose tool--fixed thick cylinder pushes away it even, launch, polyurethane slurry enters solid-state softening section by liquid state, be wrapped in shank with the shank die cavity this moment, behind the zip up, cooperate by hand that the retractility of die cavity self is moulding to make it fit in shank, after the patient injury kept motionless some minutes, die cavity initiatively hardened into and rigidly fixes cover.
This utility model shank meets the anatomical physiology requirement fully with the orthopaedics external fixation system, the plastotype temperature is no more than 39 ℃, avoided some patient to bring out cardio-cerebrovascular diseases or patient's epidermis is burnt because of overheated, adopt the material that does not change body surface bio electricity potential difference and have retractility, avoided the generation of skin allergy situation.
Above embodiment is only for the usefulness that this utility model is described, but not to restriction of the present utility model, person skilled in the relevant technique, under the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
