  • BACKGROUND OF THE INVENTION
  • (1) Field of the Invention
  • The present inventive concept, among other uses and applications, primarily relates to an improved surgical instrument and a method which will enable a physician to perform laparoscopic or endoscopic surgery with a minimum amount of bodily incisions to a patient's body. The device under consideration is an improvement on what is known in the medical profession as a grasper.
  • Graspers come in a wide of variety of functional designs, which are intended for specific purposes. Various types of graspers include tissue, claw, sharp tooth, endo-clinch, alligator, aggressive, cobra tooth, spoon, cup, babcock, DeBakey, and Allis graspers.
  • (2) Description of the Related Art
  • Graspers are used to clasp bodily tissue or an internal organ and, often to reposition the tissue or organ for better utilization of other instruments which may be required during a laparoscopic surgical process. The grasper is typically inserted into the abdominal cavity by means of insertion through the inner channel of a trocar, said trocar having been initially used to pierce the abdominal wall in the vicinity of the subject organ or tissue. Usually, a second trocar is also required as a means of inserting other surgical instruments to perform operations on the organ or tissue being held by the grasper.
  • Over the years, various surgical instruments and complex trocar designs have been devised to perform separate multiple functions during laparoscopic surgery. A recent patent, U.S. Pat. No. 7,318,802 (Suzuki, 2008), discloses a combination of an endoscope and a grasping device which, when used together, are suited for operationally treating gastro esophageal reflux disease. The grasping device is specially designed for holding tissue formed at the junction the stomach and esophagus.
  • U.S. patent application publication #2005/0149066 (Stafford, 2005) presents a device for laparoscopically suturing tissue, comprising an elongated shaft which, upon being inserted through the abdominal wall, deploys two mechanical arms, each arm having a means of receiving a needle and its respective suture.
  • U.S. patent application publication #2009/0062816 (Weber, 2009), discloses an apparatus comprising a manually operated handle attached to the proximal end of a lengthy shaft. The handle further comprises two separate mechanical operating devices, one being attached to a pair of grasping jaws at the distal end of the shaft and the other device serving to advance suture to two needles, also at the distal end of the shaft. The handle may mechanically advance the suture.
  • U.S. patent application publication #2007/0123914 (Lizardi et al, 2007) presents a needle passer instrument which has a needle engaging cartridge in the upper jaw and a surgical needle with attached suture mounted in the lower jaw. A needle actuation rod engages the surgical needle and pushes the needle through tissue contained between the jaws of the device.
  • BRIEF SUMMARY OF THE INVENTION
  • The present inventive concept, among other uses and applications, relates to an apparatus and method by which a physician may perform laparoscopic or endoscopic surgery with improved ability to reposition a body organ or tissue during the surgical procedure. An important object of the apparatus and method disclosed is to minimize the number of incisions and/or trocar placements into the abdominal wall during the course of a surgical procedure, while providing enhanced retraction capability to the physician.
  • The primary components of the apparatus include a detachable grasping device comprising a detachable head, a grasper handle removably fixed to the detachable head, at least two needles on suture, which needles may be removably attached to the detachable head, and a puppet/storage handle maintained exteriorly to the abdominal wall.
  • Initiation of the surgical process is begun with the placement of a trocar through the abdominal wall of the patient. The grasping device is inserted through the channel of the trocar and positioned proximate the organ or tissue to be operated upon. Once the organ is grasped by the detachable head of the grasping device, the grasper handle is removed from the detachable head. A secondary grasper is then inserted through the trocar for the purpose of removing the first of the two needles on suture from its retention means on the detachable head. The respective suture remains within its retention mechanism on the detachable head. The secondary grasper is then manipulated to a desired location or exit point on the interior of the abdominal wall, at which exit point the first needle and suture is impelled outwardly through the abdominal wall.
  • The foregoing procedure is repeated with the second needle and suture. Once outside the abdominal wall, the two needles and sutures are inserted into opposite ends of the storage handle. The storage handle then becomes the means by which the operator may retract or reposition the organ as required for better vision and assessment during the surgical procedure. The puppet/storage handle may move either of the two stored needles/sutures, thereby directly re-positioning the organ at the point where the detachable head is grasping the organ.
  • The reader is advised that, for the sake of convenience and clarity, the operation of this device has been described primarily with respect to the human body. However, the inventive concept is also suitable for use by veterinarians and other professionals where anatomical procedures internal to a vertebrate body are necessary. Therefore, the descriptions rendered herein are not considered to be restrictive or limiting of the operation of the device.

  • DETAILED DESCRIPTION OF THE INVENTION
  • The description of this inventive concept will begin with reference to FIG. 1, where it can be seen that the general objective of the inventive concept is to attach the distal ends of suture one 16 and suture two 17 to the surgical object, assumed to be a body organ 29, by means of a detachable grasper head 5. The proximal ends of the sutures 16, 17, having been attached to needles 14, 15, are removed from the abdominal cavity by piercing, from inside to outside, the abdominal wall 28. For the sake of convenience and easy reference, said needles 14 and 15 shall be referred to as Keith needles, although any other surgical needle suitable for the purposes herein may also function in this inventive concept. Exteriorly, the Keith needles 14, 15 are then inserted into the opposite respective ends of a dual puppet handle 20. The dual puppet handle 20 may then be manipulated by the physician, at a variety of gentle pulling angles, to retract or reposition the body organ 29.
  • The surgical procedure is initiated by the placement of an initial trocar device 30 through the abdominal wall 28, 27. The penetration point of the initial trocar 30 becomes the working port 35 for the surgery. Utilizing the initial trocar 30, an endoscope 4 is inserted into the channel of the trocar 30 and maneuvered to position the instrument proximate the body organ 29 which is the subject of the surgical procedure. The trocar 30 may need to be gradually pressed to a greater depth, since immediately afterwards, the separable grasping device 1 is inserted, parallel to the tube of the endoscope 4, through the channel of the initial trocar 30.
  • By turning the attention to FIG. 6, it is observed that greater capability for surgical adaptation is provided with the insertion of a second detachable head 5 a attached to a different location on the body organ 29. Thus, the physician may make more minute, or differently-oriented, placements of the body organ 29 for better access. The second detachable head 5 a may be manipulated via its own third suture 33, which will likely be affixed to a third stem of the puppet handle 20 (as depicted in FIG. 8).
  • FIG. 2 depicts a generic universal grasper device 38 which is typical of embodiments of the inventive concept. The device may operate by several differing combinations of means for, and methods of connection. Once the device 38 is inserted through the initial trocar 30, the grasper's upper jaw 6 and lower jaw 7 are placed at the desired site on the subject tissue or body organ 29. Upper jaw and lower jaw motion control means 10, 11 are then operated through a connective means to gently close the grasper's upper jaw 6 and lower jaw 7 at the selected location. A jaws locking means 8 may be operated, through a jaws locking mechanism 8 a, to securely attach the grasper head 5 to the body organ 29.
  • Generally, the detachable grasper head 5 can be separated from its grasping handle 2 by a head detaching mechanism 9 a which transmits control inputs through linkage to a head detaching means 9. At the time of separation, the needle one retainer 40 and needle two retainer 41 are also activated so as to release needle one 14 and needle two 15. Suture-harnessing means 18, 19 hold the respective sutures for needle one 14 and needle two 15. The two needles remain close to the grasper head 5 for the ensuing capture by a needle driver which is used to execute a piercing-type exit of each needle 14, 15 and its respective suture through the abdominal wall 28.
  • As we turn our attention to a different embodiment, FIG. 3 and FIG. 3A show a separable grasping device 1 which is observed to be a combination of a grasping handle 2, disconnected from its detachable grasper head 5. The detachable grasper head 5 further comprises an upper jaw 6, lower jaw 7, a jaws locking means 62, a head detaching means 9, and two suture harnessing means 18, 19. Provisions may also be made for needle retention mechanisms proximate, or on, the detachable grasper head 5.
  • At the proximal end of the separable grasping device 1, as shown in FIG. 3, the upper and lower jaw control means 10, 11 are operated by a threaded locking rod 64 so as to open the upper and lower jaws 6, 7 of the detachable head 5. While viewing the operational site through a laparoscope 4, the upper and lower jaws 6, 7, being in the closed position, are maneuvered into a desired location adjacent to a body organ 29. The jaws are thereupon opened and then closed upon the organ 29. An appropriate connection between the threaded locking rod 64 and the upper and lower jaw motion linkages 10 and 11 effectuate the opening and closing of both jaws 6, 7. The threaded receptor 61 prevents further movement of the threaded locking rod 64, thereby locking the jaws 6, 7 and securely maintaining the body organ 29 within the grasp of the detachable head 5. If necessary, a second separable grasping device 1(a) may be inserted into the initial trocar 30 with another detachable grasper head 5(a), as shown in FIG. 6, and a separate length of a third suture 33 for additional retraction capability.
  • At the grasping handle proximal end 3(a) the head detaching means 9 is activated to disengage the spring-loaded balls 61(a) from their respective recessed seats 61(b), thereby separating the detachable head 5 from the grasping handle 2. The grasping handle 2 is then removed from the initial trocar 30 and placed in temporary storage within the puppet handle connector means 23. Suture one 16 and suture two 17, being previously attached to needle one 14 and needle two 15, are now prepared for being drawn through suture one harnessing means 18 and suture two harnessing means 19, respectively. To accomplish this, a specialized grasper or needle driver 36 is inserted into the channel of the initial trocar 30 and maneuvered into position to grasp each needle 14, 15, in sequence. Each needle is then positioned upward toward desired respective abdominal exit point one 24 and exit point two 25, as illustrated in FIG. 1.
  • Again referring to FIG. 1, at the exterior of each exit point 24 and 25, each of the two surgical needles 14, 15, along with their respective sutures 16, 17, are pulled through the outer abdominal wall 28. The needles 14, 15 are then firmly pushed into the compressible material 37 compacted into the respective stems 20(a), (b) of the dual puppet handle 20. After completion of extraction of the needles, the needle driver 36 is then withdrawn upwards through the initial trocar 30 and properly stored. At this point, the operator may place other surgical instruments into the immediate vicinity of the body organ 29. The respective exteriorly-exposed sutures 16, 17 are secured at the dual puppet handle 20 so as to enable a physician, with reference to the endoscope 4 previously inserted, to position and/or retract the body organ 29 as necessary, by well-planned incremental movements of the puppet handle 20.
  • FIG. 9 demonstrates the manner in which the handle 2 of the separable grasping device 1 is attached for storage to the upper surface of a dual puppet handle 20 while the associated detachable head 5 is in use during the surgical procedure.
  • FIGS. 10A through 10D illustrate the basic workings of another embodiment of the inventive concept. FIG. 10A depicts an embodiment of the detachable head 5 of a separable grasping device with the upper and lower jaws 6, 7 in the closed position. Internal to the detachable head 5, and coaxially centered with the detachable head 5, is a driven shaft 51 of square cross-section which, when rotated clockwise along its axis, expands or contracts a tensionally-loaded locking ring 56. The locking ring 56, comprised of at least one winding, is affixed at one of its ends to the grasper head housing 59, and at its opposite end to the driven shaft 51. FIG. 10A shows the locking ring 56 having been expanded to near its limit, thereby causing the upper and lower jaws 6, 7 to close. FIG. 10C depicts the locking ring 56 having been tensionally released by reason of the driven shaft 51 having been rotated in the counter-clockwise direction, thereby allowing the upper and lower jaws 6, 7 to open.
  • In FIG. 10B, the handle 2 of a separable grasping device is seen to comprise a longitudinal sleeve 52, which expands at its distal end into a circular u-joint 55. The u-joint 55 contains integral spring-loaded balls 54 symmetrically spaced around the inner perimeter of the u-joint 55. Contained within the sleeve 52 is a drive shaft 50, comprising a hollow, square cross-section which runs from the distal end of the sleeve 52 to its juncture, at the proximal end of the sleeve 52, with a control wheel 57. The hollow drive shaft 50 is of precise inner cross-sectional dimensions so as to allow a snug fit over the outer walls of the driven shaft 51. In this manner, when the detachable head 5 and the handle 2 are conjoined via the u-joint 55 and the groove 53 of the detachable head 5, the drive shaft 50, by means of the control wheel 57, can incrementally turn the driven shaft 51.
  • Also connected at the proximal end of the handle 2 is a gripping handle 58 which, by longitudinal connection means, operates to release the spring-loaded balls 54 from the circumferential groove 53, thereby disengaging the detachable head 5.
  • Variations of Equipment and Methods
  • By the nature of the surgical procedures presented herein, it is evident that other variations of the devices and the methods may be utilized, according to the medical requirements of a particular surgical procedure. The following alternative structures or embodiments of devices may be readily applied: a triple-stem puppet handle 21 as illustrated in FIG. 8; a multiple-stem puppet handle 22, as illustrated in FIG. 8( a). As shown in the accompanying FIGS. 8 and 8( a), the abdominally exiting needles, needle one 14 and needle two 15 may be stored in a similar compressible material 37 as shown in the dual puppet handle 20.
  • All embodiments of the puppet handles presented thus far may be constructed with a variety of means for retention of the abdominally exiting needles, 14, 15, said means including, but not limited to, latching, clamping, grasping, hooking, constricting, and clutching. In other words, the compressible material 37 is not the sole means of securely retaining the abdominally exiting needles 14, 15 in, or proximate to, the stem of a particular puppet handle.
  • It is recognized that one knowledgeable in the medical industry and skilled in the art, has the capability to design or produce similar, or other embodiments of this inventive concept. However all such variations, alterations, or modifications are entirely conceivable as being within the intent and scope of the present inventive concept. In particular, the essence of the inventive concept is a surgical grasper comprising a detachable grasper head containing at least one length of suture, combined with the method of performing surgical manipulations with sutures attached to said grasper head and controlled exteriorly of the abdominal wall. Any number of connections, disconnecting methods, operational linkages, functions, and combinations thereof may be used to effectuate the engagement and disengagement of the detachable grasper head from its handle component.
