DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The invention relates to a device for garroting the breast for use, in particular in plastic surgery operations.
PRIOR ART
Surgery for mammary hypertrophy has become a routine operation for most plastic surgeons.
A common feature of modern techniques is the conservation of a de-epidermized thermo-glandular plate around the areola in order to provide good vascularization of the areolo-mammilary plate of the remaining glandular tissue.
The technique of de-epidermization requires the skin to be put under tension by garroting the root of the gland. Most surgeons use a knotted strip of cloth or else they need an operating theatre assistant to perform the garroting by hand.
The aim of the invention is to provide powerful and stable garroting putting the skin under maximum tension, thereby facilitating the act of de-epidermization which then becomes more accurate, and above all more rapid.
SUMMARY OF THE INVENTION
The invention provides a device for garroting the breast, characterized in that it comprises a collar of rigid material having an adjustable opening suitable for surrounding the breast and for coming into engagement therewith, and lockable in the adjusted position.
BRIEF DESCRIPTION OF THE DRRAWINGS
Other characteristics and advantages of the invention appear from the following detailed description and the accompanying drawings, in which:
FIG. 1 is a perspective view of a device in accordance with the invention;
FIG. 2 is a fragmentary section view through the FIG. 1 device; and
FIG. 3 is a profile of one jaw of the device.
BEST METHOD OF PERFORMING THE INVENTION
The device shown in FIG. 1 essentially comprises two one-piece parts 1 and 2 capable of rotating relative to each other about a pin 30, together with a ratchet-shaped bar cooperating with the parts 1 and 2 in order to hold them stably in different relative positions.
The parts 1 and 2 are identical in shape with items on the part 1 being designated in the drawings by reference numerals obtained by adding the number 10 to the reference numerals of the corresponding items on the part 1.
The part 1 is delimited by two plane faces perpendicular to the pin 30 and comprises a handle or branch 13, an arcuate portion 15 extending from one end 14 of the handle 13 to the pin 30 which passes through the portion 15, and a horn-shaped portion 16 extending from the end 14 towards the end 24 of the handle 23 of the part 2. The arcuate and horn-shaped portions 15 and 16 together constitute a rigid jaw or half-collar 10 having an inside surface 11 which is situated substantially opposite the corresponding surface 21 of the jaw 20. Together the surfaces 11 and 21 constitute the inside contour of a deformable ring or collar 30 capable of being clamped around the breast to be treated by relative movement of the parts 1 and 3. The surfaces 11 and 21 run into each other in a first zone 31 close to the pin 30 and in a second zone 32 further away from said pin. The zones 31 and 32 whose positions along the surfaces 11 and 21 vary as a function of the relative positions of the parts 1 and 2 delimit between each other portions of the surfaces 11 and 21 which constitute the inside contour of the ring, which is substantially oval in shape and which is intended to come into direct contact with the breast. In the configuration shown in FIG. 1, the surfaces 11 and 21 extend beyond the zone 32, outwardly of said contour.
An elongate link member or ratchet 40 has one end 41 attached to a hinge member fixed relative to the jaw 20 and constituted by a pin 42 mounted on the handle 23 close to its free end, and has a plurality of transverse slots 43 distributed along its length and each capable of being selected to loosely receive a peg 46 which is fixed to the jaw 10 and carried on the free end of the handle 13.
The section of FIG. 2 is taken on a plane passing through the pin 42 and the axis of the peg 46, and passing through the slot 43. As can be seen in FIG. 1, each of the slots 43 is closed at one end and communicates via its opposite end with a
