Abstract
The utility model relates to an S-shaped sacrum fixing plate. The S-shaped sacrum fixing plate is provided with a plurality of fixing holes. Compared with prior art, the S-shaped sacrum fixing plate has the advantages of safety, effectiveness, convenience in operation and the like.
Description
Technical field
This utility model belongs to technical field of medical instruments, especially relates to a kind of S type rumpbone fixing head.
Background technology
Fracture of pelvis is more common in vehicle accident, high-altitude high-energy damage such as fall, and is all unstable on vertical and horizontal direction, and rumpbone and fracture of coccyx are one of the most serious types of damage in the fracture of pelvis, and it treats difficult, and complication is more.Chinese scholars is advocated positive open reduction internal fixation treatment at present, to reduce its disability rate.Various in recent years operation fixing meanss day by day increase, as sacrum rod fix, the sacro-iliac joints screw is fixed, reconstruction plate, screw combine GaLveston technology internal fixation etc.Sacrum rod has the ability of good anti-vertical shear, but the ability reversed of nonreactive almost; When adopting the sacro-iliac joints screw fixedly, it is prone to cause caving in of nail tail loosening in the single-point contact of ilium face; Reconstruction plate has certain anti-vertical shear and anti-torsion ability, but its fixed range is limited; It is that single rod inserts the bone wing that screw combines GaLveston technology internal fixation, has the fine motion between rod and ilium.More than the biomechanical property of these factors influence internal fixation, and variously have that specification requirement is high, operation wound is big, shortcoming such as strong insufficient rigidity, nerve and blood vessel injury complication are more.
Summary of the invention
The purpose of this utility model is exactly for the defective that overcomes above-mentioned prior art existence a kind of safe and effective, easy to operate S type rumpbone fixing head to be provided.
The purpose of this utility model can realize through following technical scheme: a kind of S type rumpbone fixing head, it is characterized in that this fixing head is S-type, and fixing head is provided with a plurality of fixing holes.
Described fixing head is with the S type of sacrococcyx dorsal part dissects the S type that profile is complementary, and comprises upper arm, underarm and the intermediary transition region of turning round.
The upper arm of described fixing head and underarm are equipped with oval fixing hole, and the centre transition region of turning round is provided with circular fixing hole.
The thickness of described fixing head is 1-3mm; The major axis of described oval fixing hole is 10mm; Minor axis is 4.5mm, and the fixing head upper arm is that the distance of 13-16mm is provided with a plurality of oval fixing holes by adjacent spacing, and underarm is that the distance of 3-6mm is provided with a plurality of oval fixing holes by adjacent spacing; The diameter of described circular fixing hole is 4mm.
Described fixing head is bent titanium alloy sheet.
Compared with prior art, this utility model fixing head has the following advantages:
1. can be used as transverse fracture of the sacrum pedicle of vertebral arch and lateral mass fixing head;
2. can be simultaneously fixedly lateral masses of sacrum (ala sacralis), rumpbone pedicle of vertebral arch, sacrococcygeal joint, coccyx;
3. the fixing head design fully takes into account " S " type dissection profile of sacrococcyx dorsal part, can effectively keep reset effect;
4. the elliptical aperture design is all adopted at " S " type fixing head two ends, is convenient to adjust the screw position, and the grasp of screw fixings angle is convenient in the design of transition zone circular hole, and every broken ends of fractured bone can reach two nails and above fixing, and can reach three-dimensional fixation, and is strong reliable;
5. pedicle of vertebral arch, lateral mass, coccyx screw adopt diameter 4.5mm cancellous bone screw, and be fixing safe and effective, easy to operate;
6. fixing head adopts the titanium alloy manufacturing, intensity, histocompatibility no problem, and can bending moulding, the middle part different length be provided with the series length steel plate, to satisfy the difference between the individuality;
7. this fixing head adopts direct-view operation and three-dimensional fixation down; Avoided moulding difficulty, the puzzlement that design of nail hole and rumpbone pedicle locations are difficult to mate, thereby the danger of minimizing injured nerve through adopted common dissection armor plate to bring in the past; Practice thrift operating time, improve fixed effect.
Description of drawings
Fig. 1 is the structural representation of this utility model.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment this utility model is elaborated.
As shown in Figure 1, a kind of S type rumpbone fixing head, this fixing head are with the S type of sacrococcyx dorsal part dissects the S type that profile is complementary, so that the applying body shape is fixed, can effectively keep reset effect.
Described fixing head comprises upper arm 1, underarm 2 and the intermediary transition region 3 of turning round.Upper arm 1 is equipped with oval fixing hole 4 with underarm 2, and the centre transition region 3 of turning round is provided with circular fixing hole 5.
The thickness of described fixing head is 2mm; The major axis of described oval fixing hole is 10mm; Minor axis is 4.5mm, and the fixing head upper arm is that the distance of 15mm is provided with a plurality of oval fixing holes by adjacent spacing, and underarm is that the distance of 5mm is provided with a plurality of oval fixing holes by adjacent spacing; The diameter of described circular fixing hole is 4mm.
Described fixing head is bent titanium alloy sheet; Titanium alloy sheet tissue irritation is little, can forever keep, and shearing arbitrarily, bending, moulding to adapt to the anatomic form requirement; Can shear the length that is fit to according to actual needs according to the build of sufferer; With patient's big young pathbreaker's upper arm of build and the certain radian of underarm bending, and the length of the transition region of turning round can be set as required and bend radian, to satisfy the difference between the individuality.The pitch of holes of upper end elliptical aperture is big, and the lower end distance between borehole is little, 2 circular holes of middle employing, and diameter is consistent, changes to adapt to interpediculate distance, plants nail easily, can be used for lateral mass and fix, and also can be used for fixing the rumpbone pedicle of vertebral arch.
During use, vertically be placed on rumpbone coccyx injury along human body, the fixing head upper arm is near the rumpbone pedicle of vertebral arch of upper end, and underarm is suitable radian with the fixing head bending as required, and cuts into suitable length near coccyx, plants nail at fixing hole.
Above-mentioned S type rumpbone fixing head can be used for that reconstruction behind dislocation of transverse fracture of the sacrum, sacrococcygeal joint and fracture of coccyx dislocation, rumpbone longitudinal fracture, the Sacral Tumors resection operation is fixed or other aspects are carried out rumpbone and fixed.
The thickness of described fixing head is 1mm; The major axis of described oval fixing hole is 10mm; Minor axis is 4.5mm, and the fixing head upper arm is that the distance of 13mm is provided with a plurality of oval fixing holes by adjacent spacing, and underarm is that the distance of 3mm is provided with a plurality of oval fixing holes by adjacent spacing; The diameter of described circular fixing hole is 4mm.All the other are with embodiment 1.
The thickness of described fixing head is 3mm; The major axis of described oval fixing hole is 10mm; Minor axis is 4.5mm, and the fixing head upper arm is that the distance of 16mm is provided with a plurality of oval fixing holes by adjacent spacing, and underarm is that the distance of 6mm is provided with a plurality of oval fixing holes by adjacent spacing; The diameter of described circular fixing hole is 4mm.All the other are with embodiment 1.
