The utility model relates to an anatomical bone plate at the lower edge of the pelvic arcuate line, relates to surgical instrument manufacturing technology, and is suitable for fixing human pelvic fractures. The plate body of the utility model is a space arc-shaped curved body that matches the anatomical surface shape of the lower edge of the pelvic arcuate line. There are fixing screw holes (3) on the plate surface, and equal-strength grooves (3) are placed on both sides of the plate ( 4). The anatomical bone plate at the lower edge of the pelvic arcuate line of the utility model can be used as a template for fracture reduction at the lower edge of the pelvic arcuate line, which is helpful for testing the effect of fracture reduction, and can meet the internal fixation requirements of different types of pelvic entrances. The anatomical shape reduces the time-consuming shaping during the operation, avoids the impact of repeated shaping on the strength of the bone plate during the operation, effectively reduces the damage to the surrounding soft tissue during the mold trial process, and reduces the loss of fracture reduction, especially reducing the number of patients. Pain can also effectively reduce surgical risks and complications, and improve the success rate of pelvic fracture surgery and the effect of treatment.
Description
Technical field
Pelvis arcuate line lower edge anatomical form blade plate relates to the surgical instruments manufacturing technology, is applicable to the human pelvis fixation of fractures.
Background technology
The pelvis wound case that all kinds of traffic, building and industrial accident cause is increasing; Because pelvis special anatomical structure; Especially arcuate line place skeleton is irregular arc, needs just can appear through specific operative approach window, has abundant soft tissue to cover in anatomical structure disorder during fracture and the operative region; Make the fixing operation complicacy that resets after the fracture, also make fracture of pelvis after disability rate higher.At present clinical through pelvis arcuate line fracture fixation the time, it is moulding to adopt the standard reconstruction steel plate to carry out scene according to pelvic inlet arcuate line place anatomical shape usually, carries out fixing of fracture of pelvis; This operating technical difficulty is higher, and is consuming time longer, and is difficult to and bone surface shape matched well through moulding steel plate; Need die trial and moulding repeatedly; Thereby cause increasing the weight of the shortcoming that soft tissue injury, blade plate and bone shape do not match and cause the reduction of the fracture to be lost in the reduction of blade plate intensity, the die trial process, in addition, in the operating time that has increased sufferer; The secondary displacement that inside-fixture does not match and also possibly bring fracture increases operation risk and complication.
Summary of the invention
Deficiency to existing pelvis fracture operation; This utility model people to the research of Chinese's arcus pelvicus shape line place with the whole medial surface anatomical features of pelvis, has proposed suitable compatriots' different crowd through for a long time, can effectively reduce in the die trial process of performing the operation the damage to surrounding soft tissue; Can be used as the template that fracture of pelvis resets simultaneously; Help to check reduction of the fracture effect, reduce operation risk and complication, improve the pelvis arcuate line lower edge anatomical form blade plate of pelvis fracture operation success rate.
This utility model through as following technical scheme realize: the plate body of arcuate line lower edge anatomical form blade plate for the pelvis arcuate line under the bent body of space arc that matches of anatomic form; Blade plate adopts medical stainless steel or titanium alloy material to make; Thickness of slab is 3～4mm; Width is 14～16mm; The space length arc length of blade plate is 135～165mm, and the projection arc length degree of blade plate camber line on plane of pelvic inlet is 119.6～137.7mm, and the projection arc arc hold-carrying wire clamp angle of blade plate camber line on plane of pelvic inlet is 105.2 °～124.2 °.Plate center, blade plate plate face upper edge camber line evenly is provided with 9～10 ellipse maintenance retaining screw holes, is used for blade plate is cooperated with bony surface or surperficial soft tissue.The camber line distance is 13～16mm along the plate center at adjacent center, two retaining screw holes; Screw hole is the elliptical aperture that two semi arches of 3～4mm and line segment that two length is 2～3mm are formed by curvature; It is 0.5mm that the limit, face adapted screwing hole of blade plate and bone, edges of boards are led radius of circle, and the retaining screw hole is built-in with 1mm retaining screw countersunk seat on the non-face adapted of blade plate.The both sides of plate evenly are provided with 7～8 equal strength grooves along the side camber line, and equal strength groove and retaining screw hole are spaced along the length direction of plate, and the arc radius of equal strength groove is 4～5mm; The end of blade plate is curved, and radius of curvature is 6.5～8.0mm.Blade plate adopts cortical bone or cancellous bone screw to fix, and providing sclerite enough holds, the anatomical form shape of blade plate has reduced in the operation moulding consuming timely, avoids repeatedly the influence of moulding butt joint plate strength.
The utility model has the advantages that: arcuate line lower edge anatomical form blade plate and pelvis arcuate line lower edge anatomic form coincide good; Blade plate can satisfy the needs of the arcuate line lower edge fracture recovering of all pelvises; It is on-the-spot moulding consuming time that this utility model has reduced blade plate in the art; Avoided that the moulding bad strength of materials that causes of blade plate is lost, problem such as soft tissue injury, the reduction of the fracture are lost; Especially reduce the patient suffering, can effectively reduce operation risk and complication simultaneously, improved pelvis fracture operation success rate and efficient.

The specific embodiment
To combine accompanying drawing that this utility model is done further to detail below.
The plate body of this utility model arcuate line lower edge anatomical form blade plate is the bent body of space arc that matches with pelvis arcuate line place skeleton inner surface form; Adopt medical stainless steel or titanium alloy material to make; Thickness of slab is 3～4mm, and width is 14～16mm, the center arc length 135～165mm of plate; Plate center, plate upper edge camber line is evenly distributed with 9～10 retaining screw holes, and camber line distance is 13～16mm along the plate center at adjacent two screw hole centers, and the line segment that screw hole is 2mm by two radiuses semi arch that is 2mm and two length is formed elliptical aperture; The side of plate is along 7～8 equal strength grooves of side camber line uniform distribution, and groove and screw hole are staggered along the length direction of plate, and the arc radius of groove is 4～5mm, and the end face of plate is curved, and radius of curvature is 6.5～8.0mm.
This utility model arcuate line lower edge anatomical form blade plate is according to normal compatriots' pelvis data, can be divided into four types of android types, gynecoid type, platypelloid type, anthropoid type, android type: arc length 135～155mm; Gynecoid type: arc length 135～165mm; Platypelloid type: arc length 135～155mm; Anthropoid type: 135～155mm.Because pelvic inlet place shape also can letter be divided into horizontal ellipse clinically, and is round, vertical ellipse four types.With four types of arcuate line lower edge anatomical form blade plate center camber lines to the plane of pelvic inlet inner projection, from drop shadow curve's characteristic of three aspect gained: 1. android type plane of pelvic inlet projection arc arc hold-carrying wire clamp angle → 105.2 °, arc length → 119.6, radius of curvature → 21.4～140.5.2. gynaecoid pelvis pelvic inlet plane projection arc arc hold-carrying wire clamp angle → 115.4 °, arc length → 136.2mm, radius of curvature → 31.1～105.6.3. platypelloid type plane of pelvic inlet projection arc arc hold-carrying wire clamp angle → 124.2 °, arc length → 119.7, radius of curvature → 16.8～103.2.4. anthropoid pelvis pelvic inlet plane projection arc arc hold-carrying wire clamp angle → 117.4 °, arc length → 137.7mm, radius of curvature → 20.3～145.4.
