Abstract
A pelvis arcuate line lower edge anatomic bone fracture plate relates to the manufacturing technology of surgical appliances and is applicable to fixing fracture of the pelvis of a human body. A plate body of the pelvis arcuate line lower edge anatomic bone fracture plate is a spatial arc-shaped curve body matching with the shape of a pelvis arcuate line lower edge anatomy surface, fixing screw holes (3) are arranged on a surface of the plate, and grooves (4) with equal strength are arranged on two sides of the plate. The pelvis arcuate line lower edge anatomy type bone fracture plate can be used as a mold plate for realizing fracture reduction of a pelvis arcuate line lower edge, is beneficial for examining a fracture reduction effect, and can meet requirements of internal fixation of pelvis inlets in different types. Intraoperative shaping consumed time is shortened by the anatomic shape of the bone fracture plate, influence to strength of the bone fracture plate due to repeated intraoperative shaping is avoided, problems that surrounding soft tissues are injured in a mold testing process and fracture reduction is lost are reduced effectively, particularly, sufferings of patients are reduced, surgical risks and complications are also effectively decreased, and pelvis fracture surgery success ratio and a therapy effect are improved.
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; The inventor 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.
The present invention 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.
Advantage of the present invention is: 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 the present invention 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 the present invention is made further detailed description below.
The plate body of arcuate line lower edge anatomical form blade plate of the present invention 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.
Arcuate line lower edge anatomical form blade plate of the present invention 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.
