LAPAROSCOPIC DELIVERY DEVICE
The device for laparoscopically delivering a solid material through a trocar into a body cavity comprises at least: a hollow tube defining a void therein and having a hub at a proximal end thereof, the hub having a proximal opening therein which forms a continuation of the hollow tube; the hollow tube having a prepackaged solid material therewithin; the tube having an outer diameter less than an inner diameter of a trocar through which the tube is inserted into a body cavity, the tube extending past a valve in the trocar when positioned therewithin; the hub having a diameter greater than the inner diameter of the trocar so as not to pass therethrough; and the material being suitably anchored by a string to the device so as not to become lost within the body cavity after being pushed out of the tube.
1 . A device for laparoscopically delivering a solid material through a trocar into a body cavity comprising at least:
a hollow tube defining a void therein and having a hub at a proximal end thereof; the hub having a proximal opening therein which forms a continuation of the hollow tube;
the hollow tube having a prepackaged solid material therewithin;
the tube having an outer diameter less than an inner diameter of a trocar through which the tube is inserted into a body cavity, the tube extending past a valve in the trocar when positioned therewithin;
the hub having a diameter greater than the inner diameter of the trocar so as not to pass therethrough; and
the material being anchored by a string so as not to become lost within the body cavity after being pushed out of the tube.
2 . The device of claim 1 wherein the proximal opening includes a countersunk or chamfered guide portion about a periphery thereof.
3 . The device of claim 1 wherein the hub is unitary with the tube.
4 . The device of claim 1 wherein the hub is separate from the tube.
5 . The device of claim 1 further including a plunger.
6 . The device of claim 5 wherein the plunger is separate from the device.
7 . The device of claim 6 wherein the plunger is permanently retained within the device.
8 . The device of claim 1 wherein the prepackaged solid material is sized and configured to be compactly received within the void defined by the hollow tube.
9 . The device of claim 1 wherein the prepackaged solid material is absorbent.
10 . The device of claim 1 wherein the prepackaged solid material serves as a carrier for a liquid.
11 . The device of claim 10 wherein the liquid is an antibiotic.
12 . The device of claim 10 wherein the liquid is a bioactive agent.
13 . The device of claim 1 wherein the proximal opening is sized to receive a surgical tool therethrough.
14 . The device of claim 1 wherein the material is anchored by a string to the tube.
15 . The device of claim 1 wherein the string is anchored to the hub.
16 . The device of claim 14 wherein the string is anchored to the hub by a pin.
17 . The device of claim 14 wherein the string is anchored to the hub via a spool engaged to the hub.
18 . The device of claim 14 wherein the string is anchored to a plunger.
19 . The device of claim 5 wherein the plunger has a proximal end portion of greater diameter than the inner diameter of the tube.
20 . The device of claim 5 wherein the plunger includes a sealing element for sealing against inner structure of the device when received therein.
21 . A solid absorbent surgical pad and tubular laparoscopic delivery device therefor comprising, a pad formed from a water absorbent sterile fibrous material that is folded, coiled or rolled into an elongated rod shaped member and is compressed to a size which is reduced sufficiently to be passed into a tube comprising a body of a delivery device that is sized, constructed and arranged to be at least partially inserted into a trocar and the pad is slidably and removably retained within the delivery device, and
a flexible tether is connected between the pad and the delivery device to prevent the loss of the pad following ejection of the pad from the delivery device into the body of the patient.
22 . The surgical pad and delivery device of claim 21 wherein the tether is a string and the pad is connected by the string to a hub that acts as an anchor on the delivery device by preventing the delivery device from passing entirely through the trocar.
