  • Patent number: 9186167
    Abstract: A laparoscopy tool includes a sheath and a control wire slideably disposed within a lumen of the sheath. The sheath has a diameter of less than 1.6 mm and is introduced through an abdominal incision. A handle axially displaces the control wire within the lumen and operates a conventional tip with wire-controlled opposing jaws that is introduced through the umbilicus and has a bore formed in its trailing end. A first set of blades in the bore engage grooves formed in the leading end of the control wire and a second set of blades engages the sheath to prevent sheath retraction. A cam displaces the second set of blades away from the sheath for sheath introduction and removal, and toward the sheath to prevent sheath retraction. The tip is removed through the umbilicus and the tool is removed through the abdominal incision when the surgery is completed.

  • Publication number: 20150282836
    Abstract: A laparoscopic device with obturator. The device facilitates extraction of specimens from a female subject's abdominal cavity through the subject's vagina by also facilitating the suturing of a mesh to the anterior and posterior walls of the subject's vagina. The device includes an elongate sheath that has a flat surface on the front, a curved shape on the back, and an inner port opening formed within the flat surface, where the port opening that enables introduction of instruments or removal of specimens from the peritoneal cavity. An internal obturator can be inserted into the sheath to reduce the size of the port opening into the peritoneal cavity, or can be used to close the inner port opening into the peritoneal cavity. The obturator and sheath can be utilized as firm surfaces against which a user can suture a sacrocolpopexy mesh to the anterior and posteriors vaginal walls.

  • Publication number: 20140288486
    Abstract: In laparoscopic surgery, small (5-12 mm diameter) incisions are made in the abdominal wall through which instruments dissect and remove specimens that may be several centimeters in diameter. Removal of the sample typically requires either enlarging these incisions or morcellating the sample to pass through the sub-centimeter ports. The laparoscopic device permits extraction of the sample to be removed in a female using the vagina, which has sufficient elasticity to accommodate removal of large specimens. The posterior portion of the vagina communicates to the abdomen through a few tissue layers, and is distant from vital anatomic structures. Utilizing the vagina is optimal due to its ease of access to the abdomen and repair, minimal scarring and post-operative pain, and faster recovery following surgery. A deployable collection bag is housed in a sheath, which is deployed into the vagina or abdominal cavity to extract a large (multiple-centimeter) specimen(s) through the vagina.
