Abstract
The utility model relates to an internal fracture fixer for allogeneic bone in hand surgery. Used for surgical operation of palm and phalange fractures and bone defect fracture, the fixer adopts the human allogeneic bone as the material and is bar-shaped. The fixer comprises an integrating part and an inserting part; wherein the thick part at the center is the integrating part and the thin part at both ends are the inserting part; the diameter of the inserting part at both ends varies from 2.5 to 4 millimeters and the length is 6mm; the diameter of the integrating part at the center varies from 6 to 8mm and the length varies from 5 to 12mm; and the fixer is used for healing the palm and phalange bone defects and fixing bone fracture. Fresh adult thighbone skeleton is adopted and is deep frozen for 6 months; the parenchyma is rejected; the bone tissue surface is cleaned by clear water and then is cut into bone strips 10mm wide, which are machined and formed by the lathe and dressed by the precision lathe; and then perform vacuum drying and radiosterilization to get the finished product. The internal fracture fixer has the advantages of good biocompatibility, no necessity of second removal, low immunologic rejection; and good applicability and effectiveness in clinical practice.
Description
The application divides an application, the application number of its original application: 200520062843.0, and the applying date: on August 15th, 2005, patent name: allogeneic bone hand surgery fracture internal fixation device.
Technical field
This utility model is the fixture of homogeneous allogenic bone transplantation material, is used for hands surgery fracture internal fixation, emerging system, relates to biomaterial and learns and the hand surgery field.
Technical background
Hand skeleton and articulation structure complexity in the scope that accounts for human body only about 1%, have 29 skeletons altogether approximately, have formed about 23 joints.Normal B﹠J structure, meticulous, the flexible and changeable function that guaranteed that both hands have, but because of due to the reasons such as wound fracture the hand bones and segmental defect comparatively more sees, cause deformities such as nonunion, cripetura, skew, have a strong impact on the function and the profile of hands.In China, the hand injury patient mostly is industrial injury institute extremely at present, and wound can cause fracture, the damage of blood vessel, nerve, tendon and skin soft tissue.The fracture internal fixation is the basis in the Clinical Processing of hand injury, and is bad if fracture is handled, the lighter's malunion, and weight person even bone does not connect, the identical adverse consequences that causes of giving blood vessel, nerve, tendon, the trouble that severe patient causes replanting or reproducing refers to necrosis.
The bone defect repair is an important topic and a thorny difficult problem in the orthopaedics field always, and for a long time, the reparation that bone is damaged mainly is to adopt autologous bone transplanting, curative effect the best, but the bone source is limited.In before hand fracture is handled various ways is arranged, as steel plate, Kirschner wire etc., its curative effect is reliable, but need second operation to take out, or causes the postoperative joint function disturbance because of fixing joint.Clinically at present more adopt through freeze deeply, lyophilizing, decalcification or other chemically treated homogeneous allogenic bones, it is from the body ossification, the bone inductive effect bone conduction effect is also better.
Summary of the invention
This utility model purpose is at above-mentioned palm or phalanx bone fracture and bone defect fracture surgical treatment, and help patient's rehabilitation, design a kind of allogeneic bone hand surgery fracture internal fixation device, its raw material behaviour homogeneous allogenic bone, be shaped as clavate, form by fusion portion and insertion section, middle thicker part is divided into the insertion section that is that fusion portion, two ends more carefully are clavate, insertion section diameter 2.5mm～4mm, the length 6mm at two ends, the intermediary fusion diameter 6mm～8mm of portion, length 5mm～12mm, be used to repair refer to, reparation and fracture fixation that the metacarpal bone bone is damaged.
Select fresh adult thighbone to do, froze deeply 6 months, reject soft tissue,, be cut into the bone bar of wide about 10mm with flushing with clean water osseous tissue surface, through the machined into molding, again through the fine turning lathe finishing, vacuum drying, irradiation sterilization obtains finished product.
This inner fixer can be used for the processing of staff palm or phalanx bone fracture and bone defect fracture.This fixed system adopts people's homogeneous allogenic bone, handles through freezing irradiation sterilization deeply, and good biocompatibility need not secondary and gets and remove; Immunological rejection is low; The biomechanics test reaches required bending resistance of human fracture's internal fixation and shear strength; From body broken bone ossification is arranged, can form callus with host bone in the short period and link.Being used for clinical practice makes this holder have more practicality and effectiveness.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, this kind hands surgery bone fracture internal fixing device, middle thicker part is divided into fusion portion 2, what two ends more carefully were clavate is insertion section 1, the insertion section diameter 2.5mm at two ends, length 6mm, the intermediary fusion diameter 6mm of portion, length 5mm, it is damaged to be used for middle finger proximal phalanx bone.
Claims (1)
1. allogeneic bone hand surgery fracture internal fixation device, be shaped as clavate, it is characterized in that forming by fusion portion (2) and insertion section (1), what middle thicker part was divided into that fusion portion (2), two ends more carefully be clavate is insertion section (1), insertion section diameter 2.5mm～4mm, the length 6mm at two ends, the intermediary fusion diameter 6mm～8mm of portion, length 5mm～12mm.
