Abstract
The invention discloses a pelvis arcuate line superior border anatomical bone plate and relates to a surgical instrument manufacturing technology. The pelvis arcuate line superior border anatomical bone plate is suitable for fixing the pelvic fracture of a human body. The pelvis arcuate line superior border anatomical bone plate is a space arc curve body which is anastomotic with the shape of the inner surface of a bone at the position of a pelvis arcuate line; a fixed screw hole (3) is arranged on the plate surface; and both sides of the plate are provided with grooves (4) with the same strength. The pelvis arcuate line superior border anatomical bone plate disclosed by the invention can be used as a die plate for reduction of the pelvis arcuate line superior border fracture and is beneficial for checking the fracture reduction effect. The requirements for fixing inside different types of pelvic inlets can be met. Due to the adoption of the anatomical shape of the bone plate disclosed by the invention, the shaping time consumption in an operation is shortened; the influence of repeated shaping on the strength of the bone plate in the operation is avoided; the problems of damage to surrounding soft tissues and fracture reduction loss in the die testing process are effectively reduced; particularly, the pain of a patient is reduced; the operation risk the complications can also be effectively reduced; and the operation success rate and the treatment effect of the pelvic fracture are improved.
Description
Technical field
Pelvis arcuate line upper limb 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 craspedodrome reconstruction 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 arcuate line upper limb place anatomical form blade plate of pelvis fracture operation success rate.
The present invention is through realizing like following technical scheme: arcuate line upper limb anatomical form blade plate plate body is the bent body of space arc, and plate face shape and pelvis arcuate line place skeleton inner surface form match.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 arc length degree of blade plate camber line at the plane of pelvic inlet place is 135.31～153.41mm, and the projection arc arc hold-carrying wire clamp angle of blade plate camber line on plane of pelvic inlet is 112.52 °～154.57 °.Plate center, blade plate plate face upper edge camber line evenly is provided with 9～10 ellipse retaining screw holes, is used for blade plate is cooperated with bony surface or surperficial soft tissue.The camber line distance is 11～14mm along the plate center at two adjacent screw hole centers; The line segment that the screw hole edge contour is 2mm by two radiuses semi arch that is 2mm and two length is formed; To lead radius of circle be 0.5mm for limit, retaining screw hole, edges of boards on the face adapted of blade plate and bone, 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 groove is 4～5mm; The end of blade plate is curved, and radius of curvature is 6～7mm.Blade plate adopts cortical bone or cancellous bone screw to fix, and providing sclerite enough maintenance power, 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 upper limb anatomical form blade plate and pelvis arcuate line upper limb anatomic form coincide good; Blade plate can satisfy the needs of the arcuate line upper limb 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 upper limb 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 11～14mm along the plate center at adjacent two screw hole centers, and the line segment that the screw hole edge contour is 2mm by two radiuses semi arch that is 2mm and two length is formed; 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 6～7mm.
Arcuate line upper limb 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 can letter be divided into horizontal ellipse clinically, and is round, vertical ellipse four types.With four types of arcuate line upper limb 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 → 121.92 °, arc length → 151.92mm, radius of curvature → 13.5～12.5mm.2. gynaecoid pelvis pelvic inlet plane projection arc arc hold-carrying wire clamp angle → 112.52 °, arc length → 153.41mm, radius of curvature → 17.5～152.5mm.3. platypelloid type plane of pelvic inlet projection arc arc hold-carrying wire clamp angle → 154.57 °, arc length → 135.31, radius of curvature → 16.5～118.9mm.4. anthropoid pelvis pelvic inlet plane projection arc arc hold-carrying wire clamp angle → 114.05 °, arc length → 150.99mm, radius of curvature → 21.9～168.1mm.
