Abstract
The utility model relates to a bone cement auriculocephalic angle supporting bracket. The bracket consists of bone cement, the whole bracket is crescent, the outer lateral surface of the bracket is concave with tilted two heads and low middle, the cross section of the bracket is basically triangular, the bracket becomes thin gradually from the bottom up, and the middle of the bracket is provided with five pores with equal spaces. The supporting bracket has the advantages that the bracket makes a formed included angle stable, durable and close to the nature to the maximum extent; the supporting bracket selects the common biomaterial bone cement, and has favorable tissue compatibility and high compression strength; the material is cheap, so a patient can bear the bracket completely; the height of the bracket can be adjusted by a raspatory according to the size of the actual auriculocephalic angle in an operation, and according to the radian change of the special auriculocephalic suleus, the bracket is folded into two parts arranged at the upper crest and the lower crest of a reconstituted ear respectively, so the operation is convenient and flexible; and the supporting bracket is quick and convenient to manufacture, shape and use, saves operation time, and improves working efficiency.
Description
[technical field]
This utility model relates to field of orthopedic surgery, specifically, is a kind of bone cement cranioauricular angle supporting bracket.
[background technology]
At present, reproduce in the operation of the second stage of cranioauricular angle shaping at ear, one of used technology is not use any supporter, and its shortcoming is that operation is not if use any supporter must cause cranioauricular angle complete obiteration, operative failure; Two of technology is to use costicartilage to do support; use special external ear protective cover simultaneously; its shortcoming one is that finishing is moulding in the operation relatively to waste time and energy; the 2nd, effect is stable inadequately and lasting; because the hardness of cartilage is not good enough; compressive deformation rate and absorbance height especially be difficult to guarantee the secular pressurized not in bed of patient.In addition, the ear protective cover requires the time wear longer, and the patient often is difficult to adhere to, and costs an arm and a leg, and domestic patient is difficult to bear.Chinese patent 02134766.2 discloses a kind of meatus acusticus dilator, Chinese patent 200610027431.2 discloses a kind of combination ear supporter, the former is a kind of artificial ear timbering material, is not the support that is used to reproduce ear, and the latter only is used for atresia auris or narrow auxiliary treatment.At present, yet there are no the artificial material report of bone cement cranioauricular angle supporting bracket.
[utility model content]
This utility model will overcome the deficiencies in the prior art, and a kind of good tissue compatibility that has is provided, easy to make and bone cement cranioauricular angle supporting bracket that cost is low.
For realizing above purpose, the technical scheme that this utility model is taked is:
A kind of bone cement cranioauricular angle supporting bracket, its integral body is crescent, observes from medial surface, its angle is the 130-160 degree, and arc length is 5.5-7.0cm, length 4.0-5.0cm, the meniscate radian of medial surface meets the radian of normal cranioauricular angle, can with the complete applying in the auricle back side; Observe from lateral surface, support is " recessed " font low in the middle of stick up at two, and the peak height of end is 0.6-0.9cm, and the middle section platform height is 0.5-0.7cm; The bottom is the crescent of the thin thick middle in two, and the widest part is 0.2-0.35cm, and the cross section of support is generally triangular, and makes progress from the bottom, and support is attenuation gradually; The aperture that has five intervals to equate in the middle of the support is convenient to static line and is passed support; During operation support is fixed in head and reproduces between the ear, support is covered, cover fascia with free skin graft by fascia behind the ear; The used material of this support is the bone cement material.
The good effect of this utility model bone cement cranioauricular angle supporting bracket:
(1) 3-D solid structure of this material is to draw according to a large amount of clinical observation and measurement data post analysis, and its each face all meets the practical situation of normal auricle, and the angle that not only reaches formation is stable lasting, and farthest near nature;
(2) select biomaterial bone cement commonly used, it has the favorable tissue compatibility---be not ostracised and expose and very high comprcssive strength---with the cranioauricular angle pressurized non-lodging that guarantees to form; This material price is cheap, and the patient can bear fully;
(3) select biomaterial bone cement commonly used, can adjust the height of support with bone file according to the size of actual cranioauricular angle in the operation, change, support is converted into two parts, place the ridge up and down that reproduces ear respectively according to the radian of special cranium ear ditch, easy to operate, flexibly;
(4) make setting and use efficient and conveniently, save operating time, increase work efficiency.
[description of drawings]
The sketch map of Fig. 1 support.
Each label among the figure is respectively: 1, middle part, 2, circular hole, 3, the end.
[specific embodiment]
Below in conjunction with accompanying drawing the specific embodiment of bone cement cranioauricular angle supporting bracket of the present utility model is described, but the embodiment that provided is provided this utility model.
Embodiment 1
Referring to accompanying drawing 1, the used material of this support is a bone cement, and its integral body is crescent, observes from medial surface: angle is 135 °, and arc length is 6.0cm, length 4.0cm; Observe from lateral surface (convex surface): support is " recessed " font low in the middle of stick up at two, and end 3 peak height are 0.8cm, and stage casing 1 podium level is 0.6cm; The bottom is the crescent of the thin thick middle in two, and the widest part is 0.3cm; The cross section of support is generally triangular, and promptly makes progress from the bottom, and support is attenuation gradually; The small sircle hole 2 that has five intervals to equate in the middle of the support is convenient to static line and is passed support; During operation support is fixed in head and reproduces between the ear, support is covered, cover fascia with free skin graft by fascia behind the ear.
Claims (5)
1. a bone cement cranioauricular angle supporting bracket is characterized in that integral body is crescent, and lateral surface is " recessed " font low in the middle of stick up at two, and cross section is a triangle, makes progress from the bottom, and support is attenuation gradually.
2. bone cement cranioauricular angle supporting bracket according to claim 1 is characterized in that the angle of described support medial surface is the 130-160 degree, and arc length is 5.5-7.0cm, length 4.0-5.0cm.
