Abstract
The utility model relates to an I-shaped joint fusion bone plate which has a flaky I-shaped structure and comprises a short transverse plate, a long transverse plate and a longitudinal connecting plate, wherein screw fixing holes are arranged on the short transverse plate and the long transverse plate. The bone plate is fixed on the condyle expansion position of metacarpophalangeal and/or interphalangeal joints by using screws through the screw fixing holes according to the condyle expansion anatomical characteristic of the metacarpophalangeal and/or interphalangeal joints to fix fusion joints, the fixing structure not only has good biomechanics intensity, but also can effectively control the rotation displacement of a fusion end, and non-fusion joints can carry out early functional exercise, grafting bones can be pressed into gaps of the fusion joints according to requirements to increase fusion success rate, meanwhile, the I-shaped design sufficiently uses the condyle expansion anatomical characteristic of the metacarpophalangeal and/or interphalangeal joints to reduce operation wounds, and the metacarpophalangeal and/or interphalangeal joint fusion is more less invasive. The utility model has the advantages of simple structure, low manufacturing cost and obvious effect.
Description
Technical field
This utility model relates to a kind of medical devices, particularly a kind of I-shaped joint fusion blade plate that is applicable to that the palm refers to and/or interphalangeal joint merges.
Background technology
Refer to and/or the interphalangeal joint afunction that at the palm due to wound or disease especially the palm refers to and/or interphalangeal joint afunction case is carried out in the practice of joint fusion fixation for treatment, mainly takes the fixed method of Kirschner wire at present.The shortcoming of this method is that Kirschner wire fixed biologically mechanical strength is limited, and the rotation displacement of wayward fusion end, makes non-fusion joint be difficult to carry out in early days functional training.In addition, joint fusion often need merge the end bone grafting, is fused into power with increase.Take the Kirschner wire immobilization treatment to limit the bone grafting amount, and can't carry out impaction bone grafting, the gap is often left at the fusion end in the operation back, has prolonged time of fusion, has reduced being fused into power.
The utility model content
The technical problems to be solved in the utility model provides a kind of I-shaped blade plate that is applicable to that the palm refers to and/or the interphalangeal joint converged fixed is treated.
The purpose of this utility model is achieved through the following technical solutions: a kind of I-shaped joint fusion blade plate, it is characterized in that: this blade plate is laminar " worker " font structure, form by hyphen plate, long transverse slat and vertical connecting plate of being connected hyphen plate and long transverse slat, on described hyphen plate and long transverse slat, the setscrew hole is set.
As preferably, described vertical connecting plate is vertical with described hyphen plate and long transverse slat.
For fixation,, on described hyphen plate and the long transverse slat two setscrew holes are set all as preferably.
For the ease of fixing time location,, a locating hole is set in described long transverse slat centre position as preferably.
For the palm of fitting better refers to interphalangeal joint, as preferably, described metacarpophalangeal joints merges the hyphen plate of blade plate and long transverse slat with small radian transverse curvature.
Because the I-shaped blade plate of this utility model design is the anatomical features according to the palm refers to and/or interphalangeal joint condyle portion expands, font structure that profile is laminar " worker ", on its hyphen plate and long transverse slat, the setscrew hole is set, by using screw that blade plate is fixed on that the palm refers to and/or the place is expanded by interphalangeal joint condyle portion in the setscrew hole, realization is to merging the fixing of joint, this fixed structure not only biomechanical strength is good, and can control the rotation displacement that merges end effectively, non-fusion joint be adapted to carry out early functional training.Fusion can be carried out impaction bone grafting in the joint space as required, can improve greatly to be fused into power; Simultaneously, I-shaped design has made full use of the anatomical features that the palm refers to and/or interphalangeal joint condyle portion expands, and reduces operation wound, makes the palm refer to (between referring to) arthrodesis Wicresoftization more.This utility model is simple in structure, cost of manufacture is cheap, but effect is obvious.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
In the accompanying drawing, the numbering of each several part is as follows: 1-hyphen plate, the vertical connecting plate of 2-, the long transverse slat of 3-, 4-locating hole, 5-setscrew hole.
The specific embodiment
As shown in Figure 1, the I-shaped joint fusion blade plate of this utility model is made by being easy to moulding material, totally be laminar, its thickness is between 1.0 to 1.2 millimeters, its profile is similar to Chinese character " worker ", has a relative long long transverse slat 3 of relatively short hyphen plate 1 with one, hyphen plate 1 and long transverse slat 3 are parallel to each other, and be connected with vertical vertical connecting plate 2 one simultaneously, hyphen plate 1, the junction of long transverse slat 3 peripheral and they and vertical connecting plate, all be processed into soft curve, especially in vertical outside of hyphen plate 1 and long transverse slat 3, all refer to and/or the physiological structure characteristics at place are expanded by interphalangeal joint condyle portion, process the gentle curve that caves inward, in order to blade plate applying skeleton and avoid damaging skeleton and perienchyma according to the palm.Transverse ends at hyphen plate 1 and long transverse slat 3 all is provided with setscrew hole 5, uses setscrew to pass setscrew hole 5 and this joint fusion blade plate can be securely fixed in to slap and refer to and/or the interphalangeal joint place.For the ease of fixing, present embodiment also is provided with a locating hole 4 in long transverse slat 3 centre positions.When undergoing surgery, can pass through these locating hole 4 preliminary fixation bone fracture plate earlier, effectively improve operation efficient and success rate.Should be noted that especially the hyphen plate 1 of present embodiment joint fusion blade plate and long transverse slat 3 all with small radian transverse curvature, can see that in the drawings hyphen plate 1 and long transverse slat 3 all slightly are bent downwardly, make its vertical connecting plate 2 be lifted by level.Because as mentioned above, this fusion blade plate is made by being easy to moulding material, so the said here small and degree radian transverse curvature is to make to a certain degree adjustment, the purpose of this adjustment is the concrete condition that adapts to the operation fixed position, and crooked limit also is as limit.Such structural design is to refer to and/or the construction features of interphalangeal joint in order to adapt to the palm, makes the blade plate skeleton of can fitting better.By the setting of said structure, this blade plate not only biomechanical strength is good, and can control the rotation displacement that merges end effectively, non-fusion joint is adapted to carry out early functional training.In addition, fusion can be carried out impaction bone grafting in the joint space as required, can improve greatly to be fused into power.Simultaneously, I-shaped design has made full use of the anatomical features that the palm refers to and/or interphalangeal joint condyle portion expands, and reduces operation wound, the palm is referred to and/or interphalangeal joint fusion Wicresoftization more.
