AN APPARATUS FOR HARVESTING A FASCIA LATA GRAFT

Abstract

A fascia lata graft harvesting apparatus that is intended to be used in surgical interventions and that allows the fascia to be harvested safely. The apparatus includes a metal part shaped like a guide strip placed under the fascia lata, a cutting tool which enables to free the graft by the shearing effect created by the end part thereof, and a clamp which fixes the fascia on the guide metal strip, thereby preventing it from sliding and at the same time ensuring that the guide metal strip is kept in position.

DETAILED DESCRIPTION OF THE INVENTION

[0041] In this detailed description, the apparatus for harvesting fascia lata subject to the present invention and the preferred embodiments thereof are disclosed only to provide a better understanding of the subject matter, such that they do not limit the scope of the invention.

[0042] A general view of the fascia lata graft harvesting apparatus (10) that has been developed to be used in surgical interventions, in order to ensure safe and accurate harvesting of fascia has been illustrated in FIG. 1. The graft harvesting apparatus (10) is basically formed of three individual parts; the guide and fascia protecting metal strip (20), the fascia cutting tool (30) and the clamp (40) that is used for preventing the fascia from sliding, and that allows the guide and fascia protecting metal strip (20) to be kept in a fixed position. The strip (20) and the cutting tool (30) are positioned to be interlocked, the clamp (40) prevents the fascia from sliding whilst allowing the metal strip to be kept in fixed position, and the harvesting application is conducted when the fascia lata graft harvesting apparatus (10) is in its integrated state.

[0043] In FIGS. 2 and 4, side and top views of the guide and fascia protecting strip (20) have been shown. The last 1 mm-portion of the strip (20) that has a width of 9-9.5 mm and is made of a material that is rigid enough to allow the strip to move under the fascia at thigh along the whole fascia up to 45 cm, creates a guillotine effect and accordingly it has bent ends suitable to perform a cutting process to free the fascia and rounded out ends (22) that do not damage proximal tissue. A measuring device (ruler) has been provided which has score lines (21) on the strip (20) that is used for measuring the amount of fascia harvested in cms while performing the application. Thus, fascia grafts in any desired lengths can be harvested. This measuring device has an uneven surface (23) starting from 21 centimeters. The uneven surface (23) prevents the clamp (40) which serves to compress the fascia from sliding. If a fascia longer than 21 centimeters is desired to be harvested, the measurement lines that are less discrete on the uneven surface (23) of the guide and fascia protecting strip can be used.

[0044] In FIGS. 3 and 5, the side and front view of the fascia cutting tool (30) has been shown. The cutting tool (31), which has the width suitable to allow the guide and protecting strip (20) extending up to 50 cm to pass through, has a separator head (32) on its last 1-2 cm-portion which wraps itself around the fascia and enables the fascia to be separated from proximal tissues. After passing the end portion of the fascia to be harvested which is separated from proximal tissues, through this cutting part, the clamp (40) is used for fixing the fascia on the guide metal strip (20). The clamp (40) both prevents the fascia from sliding by compressing it and helps the metal strip (20) be kept in its position. While the clamp (40) keeps the metal strip (20) and the end of the fascia thereon at a fixed position, the cutting part is pushed to move on the metal strip (20). During this pushing process, as the guide metal strip (20) shall slide in the duct (34) located in the cutting part (31), that is formed specifically for the guide to pass through, the strip shall not damage the fascia. The clamp (40) is formed of a clamp/release bolt (41) having an anti-sliding surface, a foot portion (42) clamping the fascia and a frame (43) allowing the clamp (40) to be positioned in the guide metal strip (20).

[0045] The sharpened end portion of the fascia cutting tool (30) comprises a cutting end portion (33) that enables the fascia to be completely released by cutting it with a shearing effect created by the last end portion (22) of the guide and fascia protecting strip (20) when the end of the process is reached after separating the fascia along the whole length of the proximal tissues.

[0046] A notch similar to a drawer rail has been formed to prevent the guide strip (20) from shifting while moving inside the cutting tool (31) and from sliding up and down. The area mentioned as a notch is the recesses located on the right and left sides of the duct (34) as shown in FIG. 5. A duct (34) has been provided inside the cutting tool (30) in order to ensure that the guide strip (20) is accurately placed therein and that it can move through it smoothly. During the application, the strip (20) can only move forward and backward without shifting upwards and downwards inside the duct (34). The guide and fascia protecting strip (20) has a length of 40 cm and the fascia cutting tool (30) has a length of 50 cm, which are different in length from each other.
