Abstract
The invention discloses a calcaneus fracture height repositor which is used for conducting height reposition on the fractured calcaneus, and belongs to the technical field of orthopedic surgical instruments. According to the technical scheme, three Steinmann pins and six telescopic sleeve rods are adopted, the Steinmann pins penetrate through the front part and the rear part of the tibia and the front part and the rear part of the calcaneus respectively, every two adjacent Steinmann pins are connected through the corresponding telescopic sleeve rod, each telescopic sleeve rod is composed of a sleeve and two ejector rods, the distance between every two adjacent Steinmann pins can be spread by rotating the corresponding sleeve through the corresponding ejector rods matched with the two ends of the sleeve in a threaded mode, and therefore the collapsing calcaneus can be repositioned in the height direction, the normal height of the calcaneus is recovered, and the front subtalar joint face, the middle subtalar joint face and the rear subtalar joint face are recovered as well. The calcaneus fracture height repositor has the advantages of being scientific and reasonable in structure, convenient to use and good in reposition effect; multiple complications caused by open reduction can be avoided, operation time is shortened, and it is ensured that the ideal effect is achieved for the operation, the long-term unsolved problems that the calcaneus reposition difficulty is high, operation time is long, and the radiation dosage is large are solved, and the calcaneus fracture height repositor is suitable for application and popularization in primary hospitals and all major hospitals.
Description
Technical field
The present invention relates to a kind of auxiliary implement that the calcaneus of fracture is carried out highly reset in orthopaedics calcaneus fracture diaplasis internal fixation operation, belong to bone surgery utensil technical field.
Background technology
Fracture of calcaneus is a kind of common damage of orthopaedic trauma, and with Falling Injury, for the most common, patient be take person between twenty and fifty as main, mostly is due to the industrial accident of building trade.The fracture of calcaneus of 60%-75% is the intra-articular fracture of displacement, the fixing first-selected Therapeutic Method that has become most displacement fractures of calcaneus in open reduction.And the intra articular calcaneal fracture of displacement is caused by high-energy damage conventionally, because calcaneus major part is spongy bone, after fracture, often can there is the compression of various corpora calcaneis, the displacement fracture of articular surface, thus cause the reduction of calcaneus height.And calcaneus operation one of is made a comment or criticism and to be comprised: highly reduction, reduction >=2cm; The calcaneal tuberosity joint angle of calcaneus (Bohler " s angle): dwindle >=15 °, disappearance or dihedral.The calcaneal tuberosity joint angle of calcaneus (Bohler " s angle), is intersected and forms to the tangent line on prolapse peak line and calcaneal tuberosity surface by peak after calcaneus, is generally 20 °-40 °.The Bohler of calcaneus " reduce at s angle, prompting gravity center of human body reach, reaction is subsided apart from lower posterior articular facet, shows the reduction of calcaneus height.
After fracture of calcaneus, there is complicated variation in form, comprises Gissane angle, Bohler " s angle, width, highly, the involutory situation of posterior articular facet (subtalar joint) etc.Calcaneus fractures object: (1). recover the profile of subtalar joint posterior articular facet; (2). the height of recovery calcaneus (Bohler " s angle); (3). recover the width of calcaneus; (4). to gap decompression under the fibula of peroneal tendon traveling; 5. recover calcaneal tuberosity in turn over line.The height (Bohler " s angle) that recovers calcaneus in this some is particularly important, and this is also that calcaneus fracture diaplasis internal fixation operation successfully one of is guaranteed.Fracture of calcaneus is the intra-articular fracture of displacement, need anatomical reduction, and calcaneus joint face position exists deeply, and this just inevitable operative incision increases, and in art, excessive tractive, can cause the catastrophic effects such as the infection of postoperative wound cutaneous necrosis, deep infection, osteomyelitis.Meanwhile, clinician can only rely on experience and X-ray examination to perform the operation, and parking position accuracy usually needs patient repeatedly to have an X-rayed in art, and in art, amount of radiation is larger and consuming time longer, and lacks the reset utensil of suitable special use.The problem of above-mentioned existence makes the fracture of calcaneus operative reduction that reaches desirable require very large difficulty, not only often therefore extends operating time, the more important thing is and can have influence on surgical effect, is unfavorable for patient's rehabilitation, is therefore not suitable for basic hospital and performs the operation.Up to the present this situation does not obtain basic change, becomes the principal element that the operation of restriction orthopaedics fracture of calcaneus obtains ideal effect, and necessary taking measures solved.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of fracture of calcaneus height positor, use this positor to carry out in vitro closed reduction to calcaneus, adjust calcaneus height, articular surface before, during and after the normal height of recovery calcaneus and distance are lower, avoid the numerous complication of open reduction, shorten operating time, guarantee that operation reaches desirable effect, be applicable to basic hospital and various big hospital and apply and promote.
The technical scheme solving the problems of the technologies described above is:
A kind of fracture of calcaneus height positor, it comprises three steinman pins and six roots of sensation telescopic sleeving rod, three steinman pins are parallel, a steinman pin is horizontally through from distal tibial, other two steinman pins pass from the front and rear of calcaneus respectively, being connected by telescopic sleeving rod respectively between any two of three steinman pins of each side, telescopic sleeving rod is comprised of sleeve and two push rods, there is respectively the screw thread that rotation direction is contrary at two ends in sleeve, one end of two push rods has respectively screw thread to match with the screw thread of sleeve, the other end of two push rods has connecting hole, steinman pin is through in connecting hole fastening by hold-down screw.
Above-mentioned fracture of calcaneus height positor, the push rod close-packed arrays of two telescopic sleeving rods that are connected with other two steinman pins on a steinman pin of described each side is on steinman pin, there is pressurizing nut the inner side of the push rod of close tibia or calcaneus one side, and the screw thread of pressurizing nut and steinman pin matches.
Usefulness of the present invention is:
The present invention adopts three steinman pins and six roots of sensation telescopic sleeving rod, steinman pin is through respectively the front and rear part of tibia and calcaneus, between steinman pin, be connected with between two telescopic sleeving rod, the sleeve of rotary extension loop bar can launch the distance between steinman pin with the push rod of telescopic sleeving rod, thereby the calcaneus subsiding is resetted in short transverse.The present invention is when implementing closed reduction operation to calcaneus, according to CT, carry out Sanders typing, define each sclerite position, reset in vitro, accurate adjustment, throw according to Broden position, adjustment calcaneus height (Bohler " s angle) and Gissane angle, articular surface before, during and after the normal height of recovery calcaneus and distance are lower.That the present invention has advantages of is scientific and reasonable for structure, easy to use, reset effect is good, can avoid numerous complication of open reduction, operating time is shortened, guarantee that operation reaches desirable effect, solved and there is no the problems such as the calcaneus reset difficulty that solves is large, operating time is long, radiation dose is large for a long time, applicable basic hospital and various big hospital are applied and are promoted.
