Description

Technical Field

[0001] This invention belongs to the field of medical device technology, and in particular relates to a glans penis seat and a circumcision stapler. Background Technology

[0002] A circumcision stapler is an instrument used in circumcision surgery. It completes the cutting and suturing process in one procedure, resulting in a clean incision, short operation time, and simple operation. The glans penis seat, a crucial component of the stapler, is the core part that directly contacts and protects the glans penis during the surgery. Its core function is to precisely cut away excess foreskin while ensuring that the glans penis and key structures are not damaged.

[0003] Currently, existing glans penis seats typically have a semi-enclosed structure for accommodating the glans. In actual surgical procedures, when the glans size is well-matched or the patient's foreskin opening is small, the glans surface tends to fit tightly against the inner wall of the seat, creating a sealed space. This prevents the air inside the seat from escaping, generating positive pressure. This hinders the full insertion of the glans into the bottom of the seat, resulting in an unstable fit between the glans and the seat. This problem causes the foreskin's fixation position to shift distally, leading to the actual incision point of the circular cutting tool being too far outward, ultimately resulting in the undesirable clinical outcome of excessively long foreskin after surgery. Summary of the Invention

[0004] In view of this, it is necessary to provide a glans penis seat and a foreskin cutting stapler to solve the above-mentioned technical problems.

[0005] A glans penis seat, used in a circumcision stapler; the glans penis seat includes: The seat body has a receiving cavity for accommodating the glans penis, and the seat body has a vent hole at the bottom of the receiving cavity, the vent hole communicating with the receiving cavity; A rod body, the rod body being connected to the base body, the rod body having an exhaust channel, the exhaust channel being connected to the vent hole; The air inside the accommodating cavity can be discharged outwards through the vent and the exhaust channel in sequence.

[0006] Understandably, by creating a vent at the bottom of the cavity of the seat and using the exhaust channel of the rod to expel air from the cavity, the vent is never blocked by the glans during insertion into the cavity, allowing for complete air removal. This fundamentally avoids positive pressure interference caused by air retention within the cavity, enabling the foreskin tissue to be easily and accurately adjusted and fixed to the preset cutting position. This not only shortens the time for foreskin tissue positioning during surgery but also ensures the accuracy of the subsequent circumferential cutting position of the foreskin tissue, thereby optimizing the surgical outcome.

[0007] In one embodiment, the centerline of the vent is located on the central axis of the base.

[0008] In one embodiment, the diameter of the vent is set to D1, and D1 satisfies 0.5mm≤D1≤4mm.

[0009] In one embodiment, the exhaust channel extends along the length of the rod and penetrates the rod. The vent hole and the exhaust channel are coaxially arranged.

[0010] In one embodiment, the base is provided with a connecting cylinder, which extends away from the accommodating cavity and communicates with a vent hole; The rod portion is inserted into and connected to the connecting cylinder.

[0011] Understandably, by using an assembly method in which the rod is directly inserted into the connecting cylinder of the base, the exhaust channel inside the rod can be automatically aligned and connected with the vent hole on the base. This not only greatly simplifies the assembly process of the glans seat and effectively improves production efficiency, but also enhances the sealing and reliability of the connection between the vent hole and the exhaust channel, preventing leakage.

[0012] In one embodiment, the seat is configured as a transparent element.

[0013] Understandably, by making the glans penis seat transparent, the operator can directly observe the real-time position of the glans penis and frenulum within the cavity. This allows the operator to intuitively and accurately adjust the direction and position of the frenulum, which not only simplifies the operation but also creates conditions for subsequently determining the foreskin tissue cutting line, thus helping to ensure the accuracy of the foreskin tissue cutting position.

[0014] In one embodiment, the rod is configured as a metal tube.

[0015] Understandably, using metal tubing to manufacture the rod body leverages the material properties of metal. On one hand, it ensures the overall structural strength and rigidity of the rod body to meet the pressure requirements during surgery, thus helping to ensure the accuracy and safety of the circumcision stapler during surgical operations. On the other hand, since metal tubing is easy to cut and shape using standardized machining processes, it helps to achieve efficient and large-scale production of the rod body, thereby effectively controlling manufacturing costs while improving production efficiency.

[0016] This application also provides a circumcision stapler, including a push rod, a plurality of suture staples, and the aforementioned glans seat; The plurality of suture pins are distributed sequentially at intervals along the circumference of a preset circle; and the plurality of suture pins can simultaneously press against the knife felt of the seat body under the push of the push rod.

[0017] In one embodiment, the seat and / or the rod are provided with a plurality of positioning parts along its circumferential direction, and the plurality of positioning parts can simultaneously slide with the push rod so that the push rod is slidably connected to the glans seat; The number of the suture staples is an integer multiple of the number of the positioning parts.

[0018] Understandably, by employing a positioning part that is an integer multiple of the number of suture staples to simultaneously achieve the sliding engagement between the glans seat and the push rod, a stable guiding structure can be formed between the push rod and the glans seat, ensuring the consistency of the push rod's direction of movement relative to the glans seat, thereby ensuring the precise synchronization of the cutting and suturing actions of the circumcision stapler. On the other hand, it allows the operator to align and fit the push rod onto the glans seat from different angles, which not only facilitates operation but also avoids wrinkling or displacement of the fixed foreskin tissue due to misalignment during insertion, thus ensuring the accuracy of the subsequent cutting position of the foreskin tissue.

[0019] In one embodiment, the circumcision stapler further includes an adjustment knob that can be screwed onto the rod body for fixing the glans penis seat; The adjustment knob has a through hole. When the adjustment knob fixes the glans seat, the rod passes through the through hole and is flush with the edge of the through hole.

[0020] Understandably, aligning the rod of the glans mount with the edge of the through hole on the adjustment knob indicates to the operator that the glans mount has been accurately installed. This provides the operator with clear confirmation that the glans mount has been installed, simplifies the operation judgment process, and facilitates faster and more reliable subsequent surgical steps.

[0021] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art: The glans penis seat and foreskin cutting stapler claimed in this application, by opening a vent at the bottom of the seat cavity and using the exhaust channel of the rod to expel air from the cavity, ensures that the vent is never blocked by the glans penis during insertion into the seat cavity, and achieves complete air expulsion from the cavity. This fundamentally avoids positive pressure interference caused by air retention in the cavity, allowing the foreskin tissue to be easily and accurately adjusted and fixed to the preset cutting position. This not only shortens the time for foreskin tissue positioning during surgery, but also ensures the accuracy of the subsequent circumferential cutting position of the foreskin tissue, thereby optimizing the surgical outcome.

Detailed Implementation

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] It should be noted that when a component is said to be "located on" another component, it can be directly located on the other component or may have an intervening component. When a component is considered to be "located on" another component, it can be directly located on the other component or may have an intervening component. When a component is considered to be "fixed to" another component, it can be directly fixed to the other component or may have an intervening component.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0041] like Figures 1 to 3As shown, the glans penis seat 100 claimed in this application includes a seat body 10 and a rod body 20. The seat body 10 has a receiving cavity 11 for accommodating the glans penis (not shown), and the seat body 10 has a vent hole 12 at the bottom of the receiving cavity 11, which communicates with the receiving cavity 11. The rod body 20 is connected to the seat body 10 and has an exhaust channel 21, which communicates with the vent hole 12. Air in the receiving cavity 11 can be discharged outwards through the vent hole 12 and the exhaust channel 21 in sequence. It should be noted that when the glans penis is received in the receiving cavity 11 of the seat body 10, the foreskin tissue will be attached to the outside of the seat body 10. During this process, the glans penis will compress the air in the original receiving cavity 11, pushing the air outwards through the vent hole 12 and the exhaust channel 21 in sequence.

[0042] As can be seen from the above, the glans seat 100 of this application opens a vent 12 at the bottom of the cavity 11 of the seat body 10 and uses the exhaust channel 21 of the rod body 20 to exhaust the air in the cavity 11. This ensures that the vent 12 is never blocked by the glans during the process of the glans being inserted into the cavity 11 of the seat body 10, and achieves the complete exhaust of the air in the cavity 11. This fundamentally avoids the positive pressure interference caused by the retention of air in the cavity 11, allowing the foreskin tissue to be easily and accurately adjusted and fixed to the preset cutting position. This not only shortens the time for positioning the foreskin tissue during the operation, but also ensures the accuracy of the subsequent circumferential cutting position of the foreskin tissue, thereby optimizing the surgical effect.

[0043] like Figure 2 , Figure 3 As shown, in one embodiment, the center line of the vent 12 is located on the central axis of the seat 10. That is, in this embodiment, the vent 12 of the glans seat 100 is located at the center of the seat 10, which ensures that the glans inserted into the receiving cavity 11 will not block the vent 12.

[0044] The ventilation hole 12 is configured to be one in number and is circular in shape, so as to facilitate the machining of the ventilation hole 12 on the base body 10. Specifically, the diameter of the ventilation hole 12 is set to D1, and D1 satisfies 0.5mm≤D1≤4mm.

[0045] Here, the diameter D1 of the vent 12 is set to 0.5mm, 1mm, 2mm, 2.3mm, 3.5mm, or 4mm. Of course, it is not limited to this; the diameter D1 of the vent 12 can also be set to other values, depending on the specific design requirements for air exhaust within the cavity 11 of the seat 10. In addition, multiple vent holes 12 can be opened at the bottom of the cavity 11 on the seat 10 to ensure the air exhaust requirements within the cavity 11, which will not be elaborated here.

[0046] like Figure 7 As shown, the base 10 has a knife felt 101 and an anvil plate 102 installed sequentially around its receiving cavity 11. The knife felt 101 is located inside the anvil plate 102 to provide a flat cutting support surface for the cutting blade 110, so that the cutting blade 110 can smoothly complete the cutting of the foreskin tissue. The anvil plate 102 is used to withstand the firing force of the suture staple 120. Through the interaction between the anvil plate 102 and the suture staple 120, the hemostatic pad 130 can be stably pressed against the wound position of the foreskin tissue to close the wound and stop the bleeding.

[0047] In one embodiment, the seat 10 is configured as a transparent component. Specifically, the seat 10 can be a transparent structure made of engineering plastics such as acrylic or polycarbonate (PC). This allows the operator to directly observe the real-time position of the glans penis and frenulum within the receiving cavity 11, enabling the operator to intuitively and accurately adjust the direction and position of the frenulum. This not only simplifies the operation but also creates conditions for subsequently determining the foreskin tissue cutting line, thus helping to ensure the accuracy of the foreskin tissue cutting position.

[0048] like Figure 2 As shown, in one embodiment, the seat 10 is provided with a connecting cylinder 13, which extends away from the accommodating cavity 11 and communicates with the vent hole 12; and the rod 20 is partially inserted into the connecting cylinder 13 and connected to the connecting cylinder 13. That is to say, in this embodiment, the rod 20 is directly inserted into the connecting cylinder 13 of the seat 10 to achieve automatic alignment and communication between the exhaust channel 21 inside the rod 20 and the vent hole 12 on the seat 10. This not only greatly simplifies the assembly process of the glans seat 100 and effectively improves production efficiency, but also enhances the sealing and reliability of the connection between the vent hole 12 and the exhaust channel 21, preventing leakage.

[0049] Here, the connecting cylinder 13 and the base 10 are connected as one unit, and the rod 20 and the connecting cylinder 13 can be connected by screws, adhesives, or other methods. Of course, this is not the only option; those skilled in the art can also use an insert injection molding method to form the base 10 onto the rod 20, which will not be elaborated here.

[0050] like Figure 2 As shown, in one embodiment, the exhaust channel 21 extends along the length of the rod 20 and penetrates the rod 20, and the exhaust channel 21 is coaxially arranged with the vent hole 12. This allows the air in the accommodating cavity 11 of the seat 10 to flow along the length of the rod 20 and be discharged outward after passing through the vent hole 12.

[0051] Preferably, the rod 20 is configured as a metal tube, which allows it to be manufactured based on existing metal tubes. This ensures the overall structural strength and rigidity of the rod 20 to meet the pressure requirements during surgery, thus helping to ensure the accuracy and safety of the circumcision stapler 1000 during surgical operations. Furthermore, the metal tube material is easy to cut and shape using standardized machining methods, which helps to achieve efficient and large-scale production of the rod 20, thereby improving production efficiency while effectively controlling manufacturing costs.

[0052] Here, the rod 20 is machined with an external thread 22 at the end away from the seat 10 to meet the needs of the subsequent use of the glans seat 100 in the circumcision stapler 100, which is locked by the adjustment knob 300.

[0053] like Figures 4 to 6 As shown, this application also provides a foreskin cutting stapler 1000, including a push rod 200, a plurality of suture staples 120 and the aforementioned glans seat 100; the plurality of suture staples 120 are distributed sequentially at intervals along the circumferential direction of a preset circle, specifically the suture staples 120 can be installed in the staple cartridge 600; and the plurality of suture staples 120 can simultaneously press against the scalpel felt 101 of the seat body 10 under the push of the push rod 200, so as to realize the suturing operation of the foreskin tissue wound.

[0054] like Figure 1 , Figure 2 and Figure 7 As shown, in one embodiment, the seat 10 and / or the rod 20 are provided with a plurality of positioning parts 30 along their circumferential direction. The plurality of positioning parts 30 can simultaneously slide with the push rod 200 so that the push rod 200 is slidably connected to the glans seat 100; wherein, the number of suture staples 120 is an integer multiple of the number of positioning parts 30. In other words, the circumcision stapler 1000 of this embodiment uses a positioning part that is an integer multiple of the number of suture staples 120 to simultaneously achieve a sliding fit between the glans seat 100 and the push rod 200. This ensures a stable guiding structure between the push rod 200 and the glans seat 100, guaranteeing the consistency of the direction of the push rod 200 when moving relative to the glans seat 100, thereby ensuring the precise synchronization of the cutting and suturing actions of the circumcision stapler 1000. On the other hand, it allows the operator to align and fit the push rod 200 onto the glans seat 100 from different angles, which not only facilitates operation but also avoids wrinkling or displacement of the fixed foreskin tissue due to misalignment during insertion, thus ensuring the accuracy of the subsequent cutting position of the foreskin tissue.

[0055] Here, the positioning part 30 is specifically configured as a limiting key integrated on the base 10 for sleeved onto the connecting cylinder 13 of the rod 20. Of course, it is not limited to this; those skilled in the art can also integrate the positioning part 30 onto the rod 20, which will not be elaborated here.

[0056] It should be noted that when the push rod 200 is fitted onto the glans head seat 100, the groove (not shown) on the push rod 200 must be aligned with the positioning part 30 on the glans head seat 100 for it to be inserted smoothly. In this embodiment, the number of positioning parts 30 is designed to be an integer fraction of the number of suture pins 120 (for example, if there are 21 suture pins 120, then the number of positioning parts 30 can be 21, 7, or 3). This ensures that the push rod 200 can be aligned with the glans head seat 100 at only a limited number of specific angular positions in its circumferential direction, thereby greatly reducing the risk of misalignment when the push rod 200 is fitted onto the glans head seat 100 and ensuring precise alignment between the two. As a preferred option, the number of positioning parts 30 is consistent with the number of suture pins 120 to achieve the most direct and reliable one-to-one correspondence.

[0057] like Figures 4 to 6 As shown, in one embodiment, the circumcision stapler 1000 further includes an adjustment knob 300, which can be screwed onto the external thread 22 of the rod body 20. Specifically, the assembly and fixation of the glans seat 100 can be achieved by the abutment limit between the adjustment knob 300 and the handle 400 of the circumcision stapler 1000.

[0058] The adjustment knob 300 has a through hole 310. When the adjustment knob 300 fixes the glans seat 100, the rod 20 passes through the through hole 310 and is flush with the edge 311 of the opening of the through hole 310. This can indicate to the operator that the glans seat 100 has been accurately installed. This provides the operator with a clear confirmation that the installation of the glans seat 100 is complete, simplifies the operation judgment process, and facilitates faster and more reliable subsequent surgical steps.

[0059] like Figures 4 to 6 , Figures 8 to 14 As shown, in one embodiment, the foreskin cutting stapler 1000 further includes a fixing ring 500, which is adapted to the glans seat 100. Specifically, the fixing ring 500 can be fitted onto the seat body 10 of the glans seat 100 to lock the foreskin tissue fitted onto the seat body 10, so as to achieve precise positioning and fixation of the foreskin tissue. This ensures the neatness and regularity of the cutting line on the foreskin tissue, thereby providing a reliable operating basis for the subsequent cutting and anastomosis operations of the foreskin cutting stapler 1000.

[0060] Specifically, such as Figure 8 , Figure 9 , Figures 11 to 14As shown, the fixation ring 500 of this embodiment includes a fixation ring body 510 and a locking member 520. The fixation ring body 510 includes a first fixation body 511 and a second fixation body 512 hinged together. The two free ends of the first fixation body 511 and the second fixation body 512 can be locked / unlocked by the locking member 520. The locking member 520 is slidably mounted on the free end of the first fixation body 511. This allows the fixation ring 500 of this embodiment to be locked / unlocked on the base 10 by sliding the locking member 520. This allows the operator to control the locking and unlocking of the fixation ring 500 simply by pushing the locking member 520, making the adjustment of the fixation ring 500 simpler and more efficient, and helping to improve the overall surgical efficiency.

[0061] The first fixing body 511 has a mounting portion 5111 at its free end, and the second fixing body 512 has a rack 5121 at its free end. The rack 5121 passes through the mounting portion 5111 and can be adjusted in position relative to the mounting portion 5111. The locking member 520 is slidably mounted in the mounting portion 5111 and has locking teeth 521. The locking member 520 has a locked position and an unlocked position. When the locking member 520 is in the locked position, the locking teeth 521 engage with the rack 5121. When the locking member 520 is in the unlocked position, the locking teeth 521 disengage from the rack 5121.

[0062] Here, the free end mentioned above specifically refers to the end of the first fixed body 511 and the second fixed body that is far away from their hinge node.

[0063] It should be noted that when the locking tooth 521 engages with the rack 5121, the locking member 520 can lock the rack 5121 to the mounting part 5111 through the locking tooth 521, so that the second fixing body 512 and the first fixing body 511 are fixed together. At this time, the first fixing body 511 and the second fixing body 512 close together and form a complete ring structure. When the locking tooth 521 disengages from the rack 5121, the locking member 520 can release the lock on the rack 5121 on the mounting part 5111, and the first fixing body 511 and the second fixing body 512 can freely unfold around their hinge node, thereby realizing the opening and closing function of the fixing ring body 510.

[0064] like Figure 10 As shown, in this embodiment, one of the locking member 520 and the mounting part 5111 is provided with a groove 522, and the other is provided with a protruding rib 5112. The rib 5112 can slide and engage with the groove 522, thereby enabling the locking member 520 to slide on the mounting part 5111.

[0065] Here, the rib 5112 is disposed on the inner peripheral wall of the mounting portion 5111, and the rib 5112 can be connected to the mounting portion 5111 as a whole; correspondingly, the groove 522 is formed on the outer peripheral wall of the locking member 520, so that the sliding fit structure between the locking member 520 and the mounting portion 5111 does not occupy additional space. Of course, it is not limited to this. Those skilled in the art can also provide the rib on the locking member 520 and the groove on the inner peripheral wall of the mounting portion 5111, which will not be elaborated here.

[0066] like Figure 12 , Figure 14 As shown, in one embodiment, the locking member 520 is further configured with a through groove 523, and a rack 5121 is disposed through the through groove 523; wherein, the locking teeth 521 are disposed on the groove wall of the through groove 523. This allows the locking member 520 to slide within the mounting portion 5111, so that when the locking member 520 moves between the locked position and the unlocked position, the rack 5121 is always kept within the through groove 523, thereby enabling the locking teeth 521 to stably engage or disengage with the rack 5121 as the locking member 520 slides, so as to satisfy the locking member 520 to precisely control the locking or unlocking between the first fixed body 511 and the second fixed body 512.

[0067] In one embodiment, the locking member 520 is disposed through the mounting portion 5111, so that the part of the locking member 520 protruding from the mounting portion 5111 can be used as a driving part for the operator to operate. The operator can control the locking member 520 to slide within the mounting portion 5111 by pushing the driving part with a single finger, thereby easily and quickly locking and unlocking the fixing ring 500. This makes the adjustment operation of the fixing ring 500 during the operation more intuitive and convenient, thereby further improving the convenience of adjustment and the overall surgical efficiency.

[0068] like Figure 10 As shown, the locking member 520 also has a first limiting part 524, which is located on the outside of the mounting part 5111. When the locking member 520 is in the unlocked position, the first limiting part 524 can abut against the mounting part 5111 to limit its movement, thereby ensuring that the locking member 520 is always limited within the mounting part 5111. This provides the operator with a clear and definite unlocking endpoint, ensuring clear feel and controllable operation. On the other hand, it reliably prevents the locking member 520 from accidentally coming completely out of the mounting part 5111, thus avoiding interference and risks that may occur during surgery due to the separation of the locking member 520, effectively ensuring the continuity of operation and overall safety.

[0069] Here, the first limiting part 524 can abut against the mounting part 5111 in a face-to-face contact manner to limit the locking member 520 when it is in the unlocked position, thereby improving the stability of the locking member 520 when it is in the unlocked position.

[0070] In this embodiment, the first limiting part 524 is disposed within the groove 522 of the locking member 520 and is integrally connected to the locking member 520. Specifically, the abutment between the first limiting part 524 and the protruding rib 5112 on the mounting part 5111 achieves the abutment and limitation between the locking member 520 and the locking member 520 when the locking member 520 is in the unlocked position, so that the first limiting part 524 does not protrude outward on the locking member 520, thus maintaining the structural compactness of the locking member 520. Of course, in other embodiments, the first limiting part 524 may also be disposed on other parts of the locking member 520 other than the groove 522, which will not be elaborated here.

[0071] like Figure 10 As shown, the locking member 520 also has a second limiting portion 525; and when the locking member 520 is in the locked position, the second limiting portion 525 can abut against the mounting portion 5111 for limiting; and when the locking member 520 is in the unlocked position, the second limiting portion 525 is housed within the mounting portion 5111. This allows the locking member 520 to utilize its second limiting portion 525 to abut against the mounting portion 5111 when sliding to the locked position. This provides a stable limiting force for the meshing of the locking teeth 521 and the rack 5121, thereby ensuring the stability of the lock between the first fixing body 511 and the second fixing body 512; on the other hand, the damping force generated by the second limiting portion 525 being housed within the mounting portion 5111 can be used to provide different operating feel and functional requirements when the locking member 520 switches between the locked and unlocked positions.

[0072] Here, the second limiting part 525 can abut against the mounting part 5111 in a line-to-surface contact manner, so that the second limiting part 525 can provide a reliable limiting force to ensure that the locking member 520 is firmly in the locked position; when the operator applies a large pushing force to the locking member 520, the characteristics of the line-to-surface contact can be used to guide the second limiting part 525 to slide and be stored in the mounting part 5111, so that the locking member 520 can be smoothly switched to the unlocked position. This takes into account the dual operational requirements of the fixing ring 500 for locking stability and rapid forced unlocking during surgery.

[0073] As can be seen from the above, when using the circumcision stapler 1000, the operator can first use the glans seat 100 and the fixing ring 500 to lock the foreskin tissue to be cut and ensure the cutting line of the foreskin tissue; then, the component with the push rod 200 is put on the glans seat 100, and the glans seat 100 is locked with the adjusting knob 300. Finally, by driving the push rod 200 to extend, the foreskin tissue can be cut and sutured in one go.

[0074] In summary, when using the circumcision stapler 1000, the operator can safely and accurately complete the surgery by following these steps: First, use the glans seat 100 and the fixing ring 500 to position and lock the foreskin tissue to clarify the cutting position; then, put the part with the push rod 200 into the glans seat 100 and lock it in place by adjusting the knob 300; finally, drive the push rod 200 to perform an axial extension movement, so that the cutting and suturing of the foreskin tissue can be completed simultaneously in one operation.

[0075] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0076] Those skilled in the art should recognize that the above embodiments are merely illustrative of the present invention and are not intended to limit the present invention. Any appropriate changes and variations made to the above embodiments within the essential spirit of the present invention fall within the scope of protection claimed by the present invention.
