Traction device for use in surgery
View Patent ↗A traction device for use in surgery is disclosed with the traction device being secured to one side of a surgical table. The traction device includes one or more traction lines which include a line-tensioning device at one end thereof and a connector at the other end thereof for attachment to the limb of a patient undergoing surgery. A tension meter is associated with each of the traction or lines with the tension meter being connected to a readout which indicates the tension or traction force being imposed in the traction line. The traction device may be used for patients undergoing shoulder surgery or other types of limb surgery.
1. A patient support for use with a surgical table for supporting a patient during shoulder surgery, comprising:
a generally inverted L-shaped frame means including an upstanding first frame portion, having upper and lower ends, and a generally horizontally extending second frame portion having inner and outer ends;
said lower end of said first frame portion being selectively rotatably secured to the surgical table about a vertical axis;
a first elongated tubular frame member, having inner and outer ends, and extending generally horizontally from the first frame portion;
a second elongated tubular frame member, having inner and outer ends, and extending generally horizontally from the first frame portion below said first tubular elongated frame member;
said outer end of said first frame member being disposed outwardly of said outer end of said second frame member;
an inverted L-shaped third frame member secured to said first frame portion and including a generally vertically extending portion and a generally horizontally extending portion having inner and outer ends;
said generally horizontally extending portion of said third frame member being disposed below said second elongated frame member;
a fourth frame member slidably adjustably received in said outer end of said first frame member and having inner and outer ends;
a fifth frame member slidably adjustably received in said outer end of said second frame member and having inner and outer ends;
a first pulley rotatably mounted at the outer end of said fourth frame member about a horizontal axis;
a second pulley rotatably mounted at the outer end of said fifth frame member about a horizontal axis;
a third pulley rotatably mounted at the outer end of said generally horizontally extending portion of said third frame member;
a first support line, having inner and outer ends, movably positioned in said first frame member and said fourth frame member and having its outer end extending outwardly from said outer end of said fourth frame member and which passes over said first pulley and thence downwardly therefrom;
a second support line, having inner and outer ends, movably positioned in said second frame member and said fifth frame member and having its outer end extending outwardly from said outer end of said fifth frame member and which passes over said second pulley and thence downwardly therefrom;
a third support line, having inner and outer ends, movably positioned in said third frame member and having its outer end extending outwardly from said outer end of said horizontally extending portion of said third frame members and which passes over said third pulley and thence downwardly therefrom;
a first line-tensioning device secured to said first support line;
a second line-tensioning device secured to said second support line;
a third line-tensioning device secured to said third support line;
said outer ends of said first, second and third support lines adapts to be secured to the arm of a patient undergoing shoulder surgery.
2. The patient support of claim 1 wherein said generally vertically extending portion of said third frame member is vertically adjustable.
3. The patient support of claim 1 wherein a first tension meter is associated with said first support line which senses the tension therein.
4. The patient support of claim 1 wherein a second tension meter is associated with said second support line which senses the tension therein.
5. The patient support of claim 1 wherein a third tension meter is associated with said third support line which senses the tension therein.
6. The patient support of claim 1 wherein first, second and third tension meters are associated with said first, second and third support lines respectively.
7. The patient support of claim 6 wherein said first, second and third tension meters are connected to a tension read-out device which indicates the tension in said support lines.
8. The patient support of claim 1 wherein each of said line-tensioning devices comprises a rotatable winch.
9. The patient support of claim 1 wherein said vertically extending portion of said third frame member is vertically adjustable.
10. The patient support of claim 1 wherein portions of said first and second frame members are interconnected by a truss means.
11. The patient support of claim 1 wherein said third frame member is connected to said vertically extending portion of said L-shaped frame means by a truss means.
