Abstract
The utility model relates to a cervical vertebra orthopaedics outer fixing system, which directly warps cervical vertebra of a person and comprises a front cavity piece and a rear cavity piece respectively provided with an inner chamber and polyurethane placed in the inner chambers of the front and rear cavity pieces. Two side ends of the front and rear cavity pieces are connected together through a connecting device, forming a sheath warping the cervical vertebra of a human body. The orthopaedics outer fixing system also comprises a forehead band integrated with the rear cavity piece into one piece. The two tail ends of the forehead band are respectively provided with a rough-face nylon hasp and a hook-face nylon hasp. The forehead band encircles the forehead in the shape of a circular structure. The cervical vertebra orthopaedics outer fixing system is advantageous in that the outer fixing system has sufficient rigidity and strength and can permeate an X-ray, and thereby the curing situation of a fracture part can be clearly known; ventilating and cleaning are facilitated in that medical staffs can freely remove the fixing system to clean and process the skin surface of the injured part based on patient requirement, which fully embodies humanized treatment.
Description
Technical field
This utility model relates to orthopaedics external fixation field, relates in particular to a kind of ceruical uertebra part 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 ceruical uertebra part (referring to the body position that human chest is above, lower jaw is following) 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 ceruical uertebra part 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 ceruical uertebra part orthopaedics external fixation system, directly be wrapped in the cervical vertebra place of human body, this orthopaedics external fixation system comprises two polyurethane that have the forward and backward die cavity sheet of inner chamber and place this forward and backward die cavity sheet inner chamber, wherein, the two side ends of described forward and backward die cavity sheet is joined together to form the sheath that directly is wrapped in human cervical spine portion by connecting device.
Above-mentioned ceruical uertebra part orthopaedics external fixation system, wherein, described orthopaedics external fixation system also comprises the forehead band of making one with back die cavity sheet, two ends of this forehead band respectively are provided with the hair side velcro respectively and collude the face velcro, around forehead structure ringwise.
Above-mentioned ceruical uertebra part orthopaedics external fixation system, wherein, described connecting device is that slide fastener or tearing are buckled.
Above-mentioned ceruical uertebra part orthopaedics external fixation system, wherein, described forward and backward die cavity sheet and forehead band are made by the flexible material that does not change the body surface potential difference and have a retractility.
Above-mentioned ceruical uertebra part 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 ceruical uertebra part orthopaedics external fixation system has enough rigidity, intensity, 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.
