DESCRIPTION:
BRIEF SUMMARY
The invention relates to an articulate splint for surgical purposes, in particular, a knee splint, as used after operations on joints. Known knee splints consist substantially of two anchor bars which are fully or partially embedded in separate plaster of Paris casts on the thigh and the lower part of the leg and are joined to each other by a joint connection. With the anchor bars are set in the plaster of Paris they are arranged such that the joint of the knee splint comes to rest alongside the knee joint so that the axes of rotation of the splint joint and the knee joint register with each other.
In known knee splints, the anchor bars are directly hinged to each other. Since these knee splints consist of stainless steel and are consequently relatively expensive, the anchor bars are often chiselled out of the plaster of Paris after use so that the knee splints can be reused. There is, however, the danger of the knee splints being thereby damaged, more particularly bent, and after they are straightened again, the deformations may result in breakage when the knee splints are used again. Such a breakage can cause injury to the patient. Naturally the same problems arise when articulate splints are used on other joints of the body, such as elbow and finger joints.
The object underlying the invention is therefore to provide a high-quality articulate splint which is less expensive to use than the known joint splints of the above-described kind, even though the anchor bars are not chiselled out of the plaster of Paris on account of the aforementioned risks involved therein. This object is attained in accordance with the invention in that the joint and the anchor bars are constructed as separate parts and the joint is releasably connected to the anchor bars. The invention is based on the consideration that the joint is by far the most expensive part of a stainless steel articulate splint, and it is therefore, above all, the joint that should be made reusable, whereas the anchor bars of relatively simple construction can be thrown away as inexpensive parts with the plaster of Paris, more particularly, the plaster of Paris casts for the thigh and the lower part of the leg.
A particularly simple releasable connection between the joint member and the anchor bars is obtainable by providing the joint with stubs joined to the anchor bars by screw connections. The stubs and the anchor bars can then overlap and be rigidly connected to one another by screws passing therethrough.
It is particularly advantageous for the stubs and the end regions of the anchor bars abutting the stubs to be bent in opposite directions from the plane extending perpendicular to the joint axis, as the joint and the connections between the stubs and the anchor bars which are thicker than the anchor bars themselves, do then not come into contact with the patient's body.
The joint of the known knee splints can only be secured in one angular position. Since the joint member of the articulate splint according to the invention can be reused and can therefore be of a somewhat more complex construction, the articulate splint in accordance with the invention enables fulfillment of a wish which has existed for a long time, namely that of providing the joint member with a detent mechanism which can be secured in several angular positions, so as to permit the patient's joint to be set at rest in various positions.
Further features, details and advantages of the invention are apparent from the enclosed claims and/or the following description and the enclosed drawings of a preferred embodiment of a knee splint constructed in accordance with the invention.
