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 dissection type bone fracture plate relates to surgical instruments manufacturing technology, is applicable to the fixing of human pelvis fracture.
Background technology
The Pelvic trauma case that all kinds of traffic, building and industrial accident cause is increasing, due to the special anatomical structure of pelvis, especially arcuate line place skeleton is irregular arc, need to just can appear through specific operative approach window, in anatomical structure disorder when fracture and operative region, there is abundant soft tissue to cover, reset fixing operation complexity after making to fracture, also make fracture of pelvis after disability rate higher.At present clinical when through pelvis arcuate line fracture fixation, conventionally adopt standard reconstruction steel plate to carry out scene according to pelvic inlet arcuate line place anatomical shape moulding, carry out the fixing of fracture of pelvis, this operating technical difficulty is higher, consuming time longer, and be difficult to and bone surface shape matched well through moulding steel plate, need die trial and moulding repeatedly, thereby cause blade plate strength decreased, in die trial process, increase the weight of soft tissue injury, blade plate does not mate with bone shape the shortcoming that causes the reduction of the fracture to be lost, in addition, in having increased the operating time of sufferer, inside-fixture does not mate the secondary displacement that also may bring fracture, increase operation risk and complication.
Summary of the invention
For the deficiency of existing pelvis fracture operation, the inventor is through the research to Chinese's pelvis arcuate line place and pelvis entirety medial surface anatomical features for a long time, applicable compatriots' different crowd has been proposed, can effectively reduce the damage to surrounding soft tissue in operation die trial process, can be used as the template that fracture of pelvis resets simultaneously, contribute to check reduction of the fracture effect, reduce operation risk and complication, improve the pelvis arcuate line lower edge anatomic bone fracture plate of pelvis fracture operation success rate.
The present invention is by realizing as following technical proposals: the plate body of arcuate line lower edge anatomic bone fracture plate be with 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, 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 end normal angle of blade plate camber line on plane of pelvic inlet is 105.2 °～124.2 °.Blade plate plate Mian Shangyanban center camber line evenly arranges 9～10 ellipse maintenance retaining screw holes, for blade plate is coordinated with bony surface or surperficial soft tissue.Two adjacent Yan Ban center, center, retaining screw hole camber line distances are 13～16mm, the elliptical aperture that the line segment that screw hole is 3～4mm by curvature two semi arches and two length are 2～3mm forms, 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 in the non-face adapted of blade plate, retaining screw hole is built-in with 1mm retaining screw countersunk seat.The both sides of plate evenly arrange 7～8 equal strength grooves along 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 to provide sclerite enough holds, the anatomical form shape of blade plate, has reduced in operation moulding consuming timely, avoids repeatedly the impact of moulding docking plate strength.
Advantage of the present invention is: arcuate line lower edge anatomic bone fracture plate and pelvis arcuate line lower edge anatomic form coincide good, blade plate can meet 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 art, the problems such as the moulding bad strength of materials loss causing of blade plate, soft tissue injury, reduction of the fracture loss are avoided, especially reduced patient suffering, can effectively reduce operation risk and complication, improve pelvis fracture operation success rate and efficiency simultaneously.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
The plate body of arcuate line lower edge anatomic bone fracture plate of the present invention is the bent body of space arc matching 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, Ban center arc length 135～165mm; Ban Shangyanban center camber line is evenly distributed with 9～10 retaining screw holes, and adjacent two Yan Ban center, screw hole center camber lines distances are 13～16mm, and the line segment that the semi arch that screw hole is 2mm by two radiuses and two length are 2mm forms elliptical aperture; The side of plate is uniformly distributed 7～8 equal strength grooves along side camber line, 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 anatomic bone fracture plate of the present invention, according to the pelvis data of Normal, can be divided into android type, gynecoid type, platypelloid type, anthropoid type's Four types, 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, round, vertical ellipse four types.By Four types arcuate line lower edge anatomic bone fracture plate center camber line to plane of pelvic inlet inner projection, the drop shadow curve's feature from three aspect gained: 1. android type plane of pelvic inlet projection arc arc end normal angle → 105.2 °, arc length → 119.6, radius of curvature → 21.4～140.5.2. gynaecoid pelvis pelvic inlet plane projection arc arc end normal angle → 115.4 °, arc length → 136.2mm, radius of curvature → 31.1～105.6.3. platypelloid type plane of pelvic inlet projection arc arc end normal angle → 124.2 °, arc length → 119.7, radius of curvature → 16.8～103.2.4. anthropoid pelvis pelvic inlet plane projection arc arc end normal angle → 117.4 °, arc length → 137.7mm, radius of curvature → 20.3～145.4.
