Description
Technical field
Technical field of medical instruments is the utility model is related to, specifically, is related to a kind of solution for Complex Acetabular
Cut open locking and be oriented to steel plate, the dissection locking guide apparatus for Complex Acetabular and matching used pilot sleeve device.
Background technology
Fracture of acetabulum, particularly account for complicated acetabular bone in the Letournel-Judet partings of all fracture of acetabulum 21.88%
The 7-10 types of compromise, it is serious fracture and injury.Fracture of acetabulum often merges the damage of other positions fracture and multiple internal organs, causes
Dead rate, disability rate are high；And position is deep, it is difficult to easily cause operation.Due to having involved the structure of the forward and backward post of acetabular bone, thus reset and
Fixation is all extremely difficult, generally requires by front and back combined approach, while the forward and backward square structure of fixed acetabular bone.It is existing to be directed to
Following several ways are mainly used in the replacement and fixation method of fracture of acetabulum：
First, fracture of acetabulum anterior-posterior reconstruction plate is fixed
Complex Acetabular for involving the forward and backward rod structure of acetabular bone previously to take this method to be fixed more.Operation needs
Want Ilioinguinal approach approach and the Kocher-Langenbeck approaches at rear in front of use simultaneously；Or using ilium stock approach is expanded, together
The structure of Shi Xianlu acetabular bone front and backs.Then consolidated at front minor pelvis edge by anatomic form bending reconstruction plate
It is fixed；At rear, posterior wall of acetabulum and rear pillar are fixed according to anatomic form bending reconstruction plate respectively.
Fracture of acetabulum is carried out in this way to fix needs while appear square structure before and after acetabular bone, it is secondary caused by operation
Wound is big, and blood loss volume during the operation is big, and post-operative recovery is slow.Further, since front Ilioinguinal approach approach, by femoral artery, femoral vein,
The important feature crossing area such as femoral nerve, therefore injured blood vessel, neural possibility are big, operation risk is high.Needed in art according to bone
Bone shape, moulding 2 to the 3 blocks of steel plates of bending, for the doctor to lack experience, operating time length, increase intraoperative hemorrhage；And manual steel
The moulding deviation of plate is big, easily causes iatrogenic displacement fracture, influences surgical effect.
2nd, fracture of acetabulum Posterior approach reconstruction plate combination direct motion front pillar lag screw is fixed
Complex Acetabular for involving the forward and backward rod structure of acetabular bone, can also take rear Kocher-Langenbeck
Approach, fix rear pillar using rear reconstruction plate and fracture, acetabular anterior column structure is fixed in combination with direct motion front pillar lag screw.
Relative to above-mentioned " fracture of acetabulum anterior-posterior reconstruction plate is fixed " mode, can have in this way
Effect reduces the operation wound of patient, but still suffers from following defect：Still need in art according to skeletal shape, bending moulding 1 to 2
Block steel plate, for the doctor to lack experience, operating time length, increase intraoperative hemorrhage, and the moulding deviation of manual steel plate is big, easily causes
Iatrogenic displacement fracture, influences surgical effect；During the inserting of direct motion anterior column lag screw, dissection mark that can be for reference compared with
Less, it is possible to injure the important features such as femoral artery, femoral vein, femoral nerve when therefore screw is inserted；In addition, direct motion anterior column lag screw
Inserting needs to change perspective position repeatedly, requires very high for radiologic technologist, and in art to the radiation damage of doctor and patient all
It is larger.
3rd, acetabular bone Posterior approach dissection locking steel plate combination direct motion front pillar lag screw is fixed
Use internal fixing steel plate for posterior acetabular wall fracture (Authorization Notice No.：CN 201389072Y) and direct motion front pillar pulling force
Screw fixes acetabular anterior column structure.
The use of this internal fixing steel plate for posterior acetabular wall fracture, avoid and steel plate bending is carried out in art, shorten hand
The art time, reduce operating difficulty.But due to needing direct motion under fluoroscopy to insert front pillar lag screw, therefore still suffer from following
Defect：Dissection mark that can be for reference during the inserting of direct motion anterior column lag screw is less, during screw is inserted, it is possible to injure
The important features such as femoral artery, femoral vein, femoral nerve；Inserting for direct motion anterior column lag screw needs to change perspective position repeatedly, for putting
Penetrate technician and require very high and all larger to the radiation damage of doctor and patient in art.
4th, reconstruction plate combination direct motion rear pillar lag screw technology in front of acetabular bone
, can be with for rear structure in Complex Acetabular without obvious displacement and some patientss of the rear wall structure without fracture
By Ilioinguinal approach approach, reconstruction plate is placed at true pelvis edge；Acetabular posterior column pulling force is inserted in direct motion under X-ray examination simultaneously
Screw.
, inevitably will be through, it is necessary to by Ilioinguinal approach approach during reconstruction plate in front of use just with this technology
Femoral artery, vein, the region of neural traveling are crossed, easily causes Accessory injury；In addition, direct motion anterior column lag screw similar to aforementioned techniques
Insert and need to change perspective position repeatedly, require very high for radiologic technologist, and to the radiation damage of doctor and patient in art
It is all larger.
Sum it up, traditional reset and fixed operation is present, operation wound is big, amount of bleeding is more, implants are more；Patient crouches
The number of drawbacks such as bed time length, postoperative complications height, therefore fracture of acetabulum reset is the problem for continuing to solve of orthopaedic trauma.
Utility model content
