16. A method for locating an umbilicus during abdominoplasty surgery, the method comprising the steps of:
attaching an umbilicus finder device to the fascia of the abdominal wall to or adjacent to the umbilicus;
locating the location of the umbilicus by feeling the location of the umbilicus finder device through skin covering the abdomen; and
forming a new umbilicus orifice.
17. The method according to claim 16, wherein the step of attaching the umbilicus finder device further comprises tacking the umbilicus finder device to the umbilicus.
18. The method according to claim 16, wherein the method further comprises stretching abdominal skin over the umbilicus finder device.
19. The method according to claim 16, wherein the umbilicus finder device comprises a plurality of projections and wherein the method further comprises pressing on the skin to cause the projections to extend through fat layers under the skin to thereby provide a tactile location of the umbilicus.
20. The method according to claim 16, wherein the method further comprises withdrawing the umbilicus finder device through the new umbilicus orifice.
21. The method according to claim 20, wherein the method further comprises cutting the umbilicus finder device prior to withdrawal through the new umbilicus orifice.
22. The method of claim 16, the step of using at least a pair of tacking sutures attaching an umbilicus finder device to the fascia of the abdominal wall further comprising the step of attaching an umbilicus finder device to the fascia of the abdominal wall so as to encircle an umbilical stalk.
23. The method according to claim 19, wherein the umbilicus finder device further comprises at least one anchoring hook extending downwardly therefrom, and wherein the step of attaching the umbilicus finder device further comprises compressing the umbilicus finder and releasing the umbilicus finder such that the anchoring hooks embed in the fascia.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A one-way valve of a variable capacity compressor for a vehicle comprising:
a valve sheet having a coolant inlet formed at the center;
a valve case provided over the valve sheet and having a plurality of coolant discharging ports along the circumferential surface;
a spool valve selectively openingclosing the coolant inlet and the coolant discharging ports in the valve case; and
a resilient member provided between the valve case and the spool valve, wherein the plurality of coolant discharging ports are spaced from each other by a predetermined distance and one of the plurality of coolant discharging ports is closed so that the spool valve is brought in tight contact with an inner wall surface of the valve case when the coolant discharging ports are initially opened not to be swayed left and right, wherein the valve case includes a first vent hole formed at the center of the top surface and a plurality of second vent holes formed around the first vent hole.
2. The one-way valve of a variable capacity compressor for a vehicle of claim 1, wherein each of the plurality of coolant discharging ports is shaped as a triangle, a trapezoid, or a quadrangle whose top side is shorter than the bottom side.
