DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] FIGS. 1-4 illustrate several embodiments of a suture holding sleeve for a laparoscopic instrument, in accordance with the claimed invention. Referring now to FIGS. 1 and 2, there an embodiment of a suture holding sleeve, generally designated at 100a, is shown. FIG. 3 illustrates another embodiment of the suture holding sleeve, generally designated at 100b. FIG. 4 illustrates another embodiment of a suture holding sleeve, generally designated at 100c.

[0012] Each of the illustrated suture holding sleeve embodiments 100a, 100b, 100c generally include a hollow tubular member 110 having a first opening 122 provided at one end of the suture holding sleeve 100a, 100b, 100c, and a second opening 124 provided at an opposing end of the suture holding sleeve 100a, 100b, 100c. The sleeve 100a, 100b, 100c further includes a generally smooth inner surface 120, and a generally knurled outer surface 130, configured to enhance a user's grip on the laparoscopic instrument and a suture. As illustrated in FIG. 1, the smooth inner surface 120 permits the suture holding sleeve 100a, 100b, 100c to be slid onto a laparoscopic instrument, such as a laparoscopic clamp LC, for example. As depicted in FIGS. 1 and 2, the knurled outer surface 130 may include a plurality of raised surfaces or lines 132 having a linear configuration 132, and positioned lengthwise about the outer surface 130 of the suture holding sleeve 100a. As depicted in FIG. 3, the knurled outer surface 130 may include a plurality of lateral raised surfaces or rings 134 positioned along the outer surface 130 of the suture holding sleeve 100b. As illustrated in FIG. 4, the knurled outer surface 130 may include a combination of a plurality of raised lines 132 positioned lengthwise and a plurality of raised rings 134, positioned along the outer surface 130 of the suture holding sleeve 100c.

[0013] The suture holding sleeve 100a, 100b, 100c may be comprised of a silicone rubber or similar type of elastic rubber material, formed from a suitable type of polymer. As such, the sleeve 100a, 100b, 100b provides sticky or adhesive properties, conducive for the suture holding sleeve 100a, 100b, 100c to fit onto a variety of of laparoscopic instruments, as well as adhere to the suture needle and/or suture within the patient's tissue or organ. The suture holding sleeve 100a, 100b, 100c may have any length, however, it is contemplated that the sleeve may have a length of approximately 10 cm. As such, the sleeve 100a, 100b, 100c length is suitable to create surface area large enough to grasp or adhere to a suture without difficulty. It is also contemplated that the suture holding sleeve 100a, 100b, 100c may have any diameter. However, it is further contemplated that the sleeve 100a, 100b, 100c may have a diameter ranging between 5 cm to 10 cm, suitable to fit onto a selected laparoscopic instrument, such as the laparoscopic clamp LC, illustrated in FIG. 1. It is further contemplated that the diameter of the suture holding sleeve 100a, 100b, 100c may vary to accommodate laparoscopic instruments having a variety of thicknesses. The thickness of the suture holding sleeve 100a, 100b, 100c may range between 1 cm to 2 cm.

[0014] In operation, prior to commencing laparoscopic surgery, a medical practitioner places the suture holding sleeve 100a, 100b, 100c onto the laparoscopic instrument, such as a laparoscopic clamp LC, as illustrated in FIG. 1. It is to be noted that although the suture holding sleeve 100a, 100b, 100c is typically positioned near the tip of the laparoscopic instrument, it is contemplated that the suture holding sleeve 100a, 100b, 100c may be positioned virtually anywhere along the laparoscopic instrument in order to aid the medical practitioner during the laparoscopic suturing process. On occasion, as a result of the tight spaces created and fluids secreted during laparoscopic surgery, the medical practitioner may find it difficult to suture an incision. As such, the suture holding sleeve 100a, 100b, 100c may be used to assist the practitioner in maintaining control of the laparoscopic instrument.

[0015] After the laparoscopic surgery has been completed, the medical practitioner typically uses sutures to close the tissue or the incision made for the surgery. If, for some reason, the medical practitioner loses control of the suture while closing up the tissue or the incision, he or she may use the suture holding sleeve 100a, 100b, 100c to engage and adhere to the suture. This will be helpful in circumstances in which the practitioner has problems seeing the suture and/or grasping suture with the alligator clips of the laparoscopic instrument. Once the practitioner engages the suture with the knurled outer surface 130 of the suture holding sleeve 100a, 100b, 100c and has control of the suture, the medical practitioner may remove the sleeve 100a, 100b, 100c from the tissue or incision and, subsequently, grasp the suture with the instrument LC, to complete the closure of the tissue and/or the incision.

[0016] It is to be understood that the present invention is not limited to the embodiments described above, but encompasses any and all embodiments within the scope of the following claims.
