Definitions
- the present invention relates to a method and apparatus for laparoscopic introduction and application of liquid, gel, and like medicinal materials.
- Each port consists of a tube with proximal and distal ends.
- a valve structure on the proximal end of the port member allows instruments to be passed through the abdominal wall while maintaining appropriate intra-abdominal CO2 pressure.
- liquids or solutions are usually administered through a common laparoscopy instrument called a suction/irrigator, aspiration irrigator, irrigator, irrigating cannula, cannula or other similar terminology.
- suction/irrigator aspiration irrigator, irrigator, irrigating cannula, cannula or other similar terminology.
- suction/irrigator aspiration irrigator
- irrigator irrigating cannula
- cannula cannula or other similar terminology.
- These are simple straight tubes usually ranging from between about
- Rinsing or irrigating fluids are flushed in to wash and moisten tissues.
- These simple tubes usually metal or plastic
- Such needles are for injection of liquid and medicines into tissues while the present invention is for applying liquid, gels and like medicinal materials onto the surface of tissues even if these products attach to or ultimately penetrate into the tissues.
- the present invention is designed for a variety of installation requirements and a variety of products.
- head designs to effect the type of delivery or delivery pattern and pass different product variations.
- Some of the heads have variously narrowing conical shapes and are designed for gels, liquids and medicines that need application to certain size local spots.
- Other heads are for dispersion of gels only, enhanced by a combination of shape (straight and widening conical) and the presence of grids. A wide (but not haphazard, wasteful, or harmful) distribution is desired.
- the grids can be angled outwardly to further cause the gel to disperse more outward to cover even more area when desired.
- Some of the heads have multiple holes at the end.
- the distal end of the main body of the instrument can be angled up to 90 degrees in two pivotal directions. When the instrument is manually rotated, this allows aiming of the selected delivery head in virtually any direction to reach any area in the abdomen (including pelvis). This also includes hard to reach areas such as parts of the intestines, the under side of the uterus, behind the ovaries and the entire anterior abdominal wall. To further reach difficult areas, the inner portion of the main body can be pushed in to move the flexible plastic tube and its applicator head farther into the abdomen to small areas, more distant areas or, most importantly, areas that could't otherwise be reached because the main body of the instrument is blocked by other tissues or organs.
- the instrument overall diameter can vary, probably between about 5 mm and 15 mm with approximately 10 mm being a preferred general size.
- the present invention thus provides a method and apparatus for laparoscopic introduction and application of a variety of liquid, gel, and medicinal materials, enabling the surgeon to more efficiently use these materials.
- all instrumentation and all surgical products must be introduced through "ports" consisting of valved sleeves or tubes.
- the present invention provides a method and apparatus for dispensing these products through a flexible tube which can be angled and adjusted to guide them to any site, including hard to reach areas.
- Interchangeable tubes allow having a variety of heads for different types of dispersement of the liquid, gel, or medicine (examples: pin-point application, broad application, shower - like spray application).
- the present invention provides an improved method and apparatus for dispensing liquid medicinal, gel, or like material into a patient's abdomen during a laparoscopy procedure.
- the method includes the surgical forming of a small opening through the patient's abdominal wall.
- a first tubular member is placed through this surgical opening, the tubular member having proximal and distal end portions.
- the second tubular member is then inserted into the bore of the first tubular member and through a valve structure that can be provided if desired on the proximal end of the first tubular member. This allows the surgeon to valve the flow of gases between the patient's abdominal and the proximal end of the first tubular member.
- the second tubular member defines an instrument body that can be extended into the patient's abdominal cavity.
- This flexible dispensing tube has a distal end with a nozzle for applying a desired liquid, gel or medicinal material to the patient's abdominal cavity with a desired distribution or spray pattern.
- the holes can be in the form of small channels with central longitudinal axes that are angled relative to the central longitudinal axis of the flexible dispensing tube
- the apparatus of the present invention provides a laparoscopy instrument that comprises a first laparoscopy tube that can be placed surgically by a surgeon through an opening in the patient's abdominal wall, the first tube having a bore
- An instrument body is provided that can be placed into the bore of the laparoscopy tube
- the instrument body has proximal and distal end portions and an instrument body bore.
- One or more flexible dispensing tubes are provided that each has a proximal and distal end.
- the tube is preferably sized and shaped to fit the instrument body bore and is flexible at least at the distal end portion thereof.
- each of the flexible dispensing tubes is in an elongated cylindrically shaped hollow tube of silicone, rubber, or rubber-like material.
- a nozzle is provided at the distal end of each of the dispensing tubes for dispensing liquids, gels and like medicinal materials into the patient's abdominal cavity
- Handles are provided on the instrument body for manipulating the distal end of the instrument body so that a contained flexible dispensing end portion of the dispensing tube can be moved in a sliding fashion. Further, a lever operates a pushrod to flex or pivot the distal end of the instrument body and the contained dispensing tube This allows a wide range of positions for placement of the nozzle within the patient's abdominal cavity
- the hollow bore of each of the dispensing tubes allows the transmission of fluid, gel, liquid, and like medicinal material between the proximal and distal end portions of the dispensing tube when the tube occupies the bore of the instrument body and the nozzle is positioned at a desired location with in the patient's abdominal cavity.
- a syringe can be attached to a proximal opening of the instrument or to an extender tube.
- the syringe (or syringe and extender tube) enables the surgeon or an assistant to push gel, liquid, and like medicinal material through the bore of the instrument.
- the assistant can push the gel, liquid, etc. while the surgeon aims and positions the instrument for delivery of the surgical product BRIEF DESCRIPTION OF THE DRAWINGS

- FIGS 1-6 illustrate the preferred embodiment of the apparatus of the present invention designated generally by the numeral 10.
- Laparoscopy instrument 0 includes an elongated structure that can be placed through the abdominal wall 11 of a patient as shown in Figure 5.
- FIG. 5 and 6 Also shown in Figures 5 and 6 is the patient's skin 12 and the abdominal cavity 13 into which an inserter instrument portion 24 of the instrument 10 will be placed.
- Tubular port 14 extends through an opening 14A formed with the tubular member 14 through the patient's abdominal wall 11. This procedure of placing a port in the abdominal wall 11 is per se known. In such a procedure, it is known in the art to inflate the abdomen to give the surgeon a better view of the surgical site.
- the tubular port 14 is a commercially available structure that includes a proximal end 15 and a distal end 16.
- the tubular port 14 provides an elongated open end cylindrical bore 17 so that the surgeon can communicate between the abdominal cavity 13 and the exterior of the patient Cylindrical bore 17 is valved with valving member 18
- the valving member 18 likewise provides a bore that is in communication with the cylindrical bore 17
- Such a port 14 with its valving member 18 is sold commercially for use in laparoscopic surgery
- An elongated inserter tube member 20 is sized and shaped to fit the internal bore 17 of the tubular port 14
- the tubular member 20 provides a generally cylindrical outer surface that is of an external diameter that is substantially the same as or slightly smaller than the internal diameter cylindrical bore 17.
- the bore 19 of valving member 18 is also generally cylindrically shaped to conform to the outer surface of tubular member 20
- the inserter tube member 20 has a proximal end 22 and a distal end 23
- the tubular member 20 has a uniform cylindrical bore 21 that is open ended
- An elongated inserter instrument 24 is comprised of external tubular member 25 and internal tubular member 27 (see Figure 7)
- the external tubular member 25 has a handle 26 for manipulating it
- the internal tubular member 27 has a handle 28
- the two handles 26, 28 are each in the form of a ring so that the surgeon can place one of his or her fingers through the handles 26, 28 for manipulating and sliding the member 27 relative to the member 25.
- External tubular member 25 has a proximal end 29 and a distal end 30.
- a grasping portion 31 is attached to the distal end 30 as shown in Figures 7 and 9-13
- Lever 32 is pivotally attached to the proximal 29 end portion of external tubular member 25
- Lever 32 is attached to pushrod 34 so that pivoting of lever 32 about its pivot 33 operates to extend or retract the pushrod relative to external tubular member 25
- the lever 32 is used to articulate grasping portion 31 into multiple angular positions relative to the central longitudinal axis of the external tubular member 25 as illustrated in Figures 10-11 and 13
- a cable 35 is attached to internal tubular member 27
- the cable 35 extends through a longitudinal bore 36 within external tubular member 25
- the cable 35 is moved by pulling or pushing the internal tubular member 27 relative to the external tubular member 25 using handles 26, 28
- An articulating joint 37 forms a connection between external tubular member 25 and grasping portion 31. As shown in Figures 10-11 and 13, a pair of spaces 38, 39 are provided at articulating joint 37 for allowing the grasping portion 31 to move left to right and angulate relative to the central longitudinal axis of external tubular member 25 as shown in Figures 10-1 1 and 13.
- a pinned connection 40 is formed at articulating joint 37 between the distal end 30 of external tubular member 25 and the grasping portion 31, allowing portion 31 to pivot upon tubular member 25.
- Pushrod 34 includes an elbow section 41 that carries button 42 The button 42 fits in a recess 43.
- the recess 43 is formed on fixed member 44 of grasping portion 31.
- a moving member 45 is placed in close approximate to the fixed member 44. The moving member 45 travels away from the fixed member 44 when the cable 35 is pulled using lever 32. Cable 35 is attached at 46 to moving member 45.
- a coil spring 47 normally holds moving member 45 in face to face contact with fixed member 44.
- cable 35 pulls down underlying support 48 and moving member 45.
- a plurality of cable guides 49-51 are used to route the cable as shown in Figure 9 to the under side of moving member 45 as shown.
- arrow 52 illustrates the movement of pushrod 34 fore and aft depending upon the surgeon's manipulation of lever 32.
- the pushrod 34 is a neutral position when the lever 32 is in an upright position, generally pe ⁇ endicular to the central longitudinal axis of external tubular member 25 as shown in Figure 7.
- arrow 53 designates a movement of moving member 45 away from fixed member 44. This is accomplished by pulling on the member 27 and its attached cable 35. Such a movement of member 45 in the direction of arrow 53 is used when either loading or releasing the sheet like member S to or from the instrument 10. The surgeon pulls the cable 35 to move member 45 away from member 44 producing a gap therebetween for application of an edge of sheet like member S thereto. In Figure 1, the gap has been formed between members 44 and 45 so that the surgeon can insert an edge of a sheet of material S into the gap formed between the members 44 and 45.
- the surgeon uses port 14 to place the sheet of material S into the patient's abdominal cavity 13. This is accomplished by routing the distal end 23 of inserter tube 20 and the contained inserter instrument 24 through the bore 19 of valving member 18 and then through the bore 17 of tubular port member 14. The surgeon projects the inserter tube 20 into the abdominal cavity 13 until the distal end 23 is positioned close to the distal end 16 of tubular port member 14 as shown in Figure 5. The surgeon then holds the inserter tube 20, fixing its position relative to the tubular port 14.
- the surgeon forces the elongated inserter instrument 24 into the abdominal cavity by moving the elongated inserter instrument 24 relative to both inserter tube 20 and port 14 so that the grasping portion 31 and the furled sheet FS of material are exposed inside the abdominal cavity 13.
- the letters FS designate the furled sheet of material having been placed with the grasping portion 31 in the patient's abdominal cavity 13.
- the surgeon then rotates the elongated inserter instrument 24 as indicated by the arrow 58 in Figure 5. This rotation unfurls the sheet of material S to the position shown in Figure 6.
- a second port (such as member 14) can be used for placing a grasping instrument 59 into the abdominal cavity 13 for assisting the surgeon in application of the sheet of material S as illustrated in Figure 6.

- Grasping portion 31 A includes a removable connection designated as 59 in Figure 14.
- Connections 62, 63 are formed between the instrument's receiving portions 31 A and 45 A and the ends 67, 69 of a pair of removable grasping portions 60, 61.
- a pre-packaged furled sheet FS of material is shown, furled about the removable ends 60, 61.
- the ends 60, 61 are pre-packaged with sheet S furled about these ends 61, 62.
- An edge of sheet FS is grasped between ends 61, 62.
- the furled sheet FS and ends 60, 6r would be contained within the bore 65 of an elongated disposable sleeve 64.
- the sleeve 64 provides a pull tab 66 so that the user can install the furled sheet FS avoiding premature unfurling by simply holding and manipulating the sleeve 64 at tab 66.
- removable end 60 provides a projection 67 that mates with a correspondingly shaped socket 3 IB of grasping portion 31 A. Similarly, the moving member
- the end members 60, 61 each provide correspondingly sized and shaped flat surfaces 60 A, 61 A that abut in face to face relation when the coil spring 47 forces members 60, 61 together.
- connection between projections 67, 69 and sockets 3 IB and 45B can be a wedge lock or taper lock type connection to ensure a tight fit.
- the removable ends 61, 62 and the furled sheet FS and sleeve 64 could be in a presterlized blister pack for example.
