Description
Technical field
This utility model is used for technical field of medical instruments, particularly relates to a kind of ankle joint tumor and merges steel plate.
Background technology
Distal tibial tumor is relatively rare, has 69 examples to occur in distal tibial, account for 2.3% in 2982 routine bone tumor of the statistics such as domestic Wang Zhen and Tumor-like Lesion.In 7974 routine bone tumor of external Campanacci statistics and Tumor-like Lesion, what occur in distal tibial has 257 examples, and sickness rate is 3.2%.This position soft tissue covers thinner, blood fortune is relatively poor, excision is more difficult reaches surgery border widely, and conventional Therapeutic Method is bulk homogeneous allogenic bone transplantation, special artificial full ankle prosthesis replacement treats this region tumors, and limb-sparing surgery infectious-related complication incidence rate is higher.Often there will be following situation: final knitting cannot occur artificial full ankle prosthese, is not suitable for this position.Main complication after application bulk homogeneous allogenic bone transplantation is the infection of rejection secondary, nonunion and allogeneic bone fracture etc., and the large sample report of its incidence rate is respectively 6%-30%, 8%-17% and 5%-20%.For ankle joint two place bone tumor defect, usual operation method carries out at twice, and its wound is large, and surgery cost is high.
Utility model content
For solving the problem, use demand according to clinical practice, for the deficiency of above operation, this utility model provides one to realize anatomic match, reduces surgery cost and wound simultaneously, and the ankle joint tumor reducing postoperative complication rate merges steel plate.
This utility model solves the technical scheme that its technical problem adopts: a kind of ankle joint tumor merges steel plate, comprise steel plate body, steel plate body has and can mate the coating surface of fitting with patient's diaphysis, described steel plate body comprises the focus portion that can coordinate with patient's diaphysis end and can with the fixed part coordinated in the middle part of patient's diaphysis, the bending with patient's diaphysis tendency is formed between described focus portion and fixed part, described focus portion has can be embraced focal area, ankle joint two place and the first fixed-wing clamped and the second fixed-wing, steel plate body is at the first fixed-wing, second fixed-wing and fixed part all arrange some fixing holes.
Be further used as the improvement of technical solutions of the utility model, described steel plate body is by passing through 3D printing shaping after the modeling of scan patients ankle joint diaphysis.
Be further used as the improvement of technical solutions of the utility model, the fixing hole in described focus portion is distributed in the surrounding of patient's diaphysis focal area, the distance >=2.7cm at the fixing hole in focus portion and edge, focal area.
Be further used as the improvement of technical solutions of the utility model, the tip forming arc-shaped in the one end away from focus portion of described fixed part, described tip has the inclined-plane that thickness reduces gradually.
Be further used as the improvement of technical solutions of the utility model, described fixing hole is common through hole or screwed lock hole.
The beneficial effects of the utility model: this steel plate body has and can mate the coating surface of fitting with patient's diaphysis, this coating surface can carry out personalized designs according to preoperative CT and MRI image, realize anatomic match, reach good bone docile effect, the postoperative stress occurring internal fixtion is avoided to concentrate, the complication such as broken nail, fracture.Simultaneously focus portion has the first fixed-wing and the second fixed-wing, thus can complete by once operation and a slice steel plate in the face of two focal area, place of ankle joint, and minimizing surgery cost and wound, reduce postoperative complication rate.In addition, first fixed-wing and the second fixed-wing are wholely set, the fixing and stable of Cranial defect end can be maintained, there is the action of compressive stress improving Cranial defect end longitudinal direction, centration, compressive stress is added by applying polymerization to Cranial defect end, Cranial defect packing material effectively can be kept to stablize, prevent bone cement to be shifted.There are efficient recovery Cranial defect end integrity and continuity, allow patient can carry out functional exercise as early as possible, the stimulation of being conducted by stress, be more conducive to the healing of Cranial defect, the recovery as early as possible of limb activity function.
