Description
- This is a continuation application that claims the benefit of and priority to currently pending U.S. non-provisional application Ser. No. 14/050,302, filed Oct. 9, 2013.
- Not Applicable.
- Not Applicable.
- These non-limiting exemplary embodiment(s) relates to medical instrument handles and, more particularly, to an ergonomic multi-functional handle used to manipulate a medical instrument such as an electrosurgical, monopolar, laparoscopic instrument, for example, while reducing user fatigue.
- Surgery is a learned skill requiring many years of training to develop an understanding of medical procedures, disease processes and healing that far exceed the basic medical principles. The surgeon must develop hand-to-eye coordination and acquire skills utilizing a variety of highly specialized medical instruments. The medical instruments and tools are an extension of the surgeon's hand. The surgeon's ability to perform the medical procedures with instruments and tools designed to benefit skill is paramount to the successful outcome for the patient. To enhance the medical performance to better serve the patient means developing instrument handles which are responsive, sensitive and ergonomically designed to benefit the natural motions of the human hand.
- For example, laparoscopic instruments have been heavily developed for use by surgeons during medical procedures since around 1980s. There are many advantages of laparoscopic surgery compared with open procedure. These advantages include: reduced hemorrhaging which reduces needing a blood transfusion, smaller incision which reduces pain and shortens the recovery time of the patient, reduced scarring, reduced chances of needing pain medication, reduced hospital stays and quicker return to everyday life, and reduced risk of contamination and infection. Disadvantages of a laparoscopic procedure include: limited range of motion in the medical site, poor depth perception by the surgeon, and often laparoscopic tools are not perceived as moving in the same direction as the surgeon's hands.
- In a variety of medical devices used for a diversity of medical or non-medical procedures, devices are designed with a dedicated handle or proximal end and a distal or actuation end. Typically medical device handles prescribe how they will be held in the hand by the layout of their handle shape or position of digit retaining portions. In instruments that contain loops, such as can be found in scissors type devices or grasping type devices, the loops are used for opening and closing the end effector, whether that is a scissors, grasper, clamp or similar device. In medical devices and more specifically minimally invasive or laparoscopic devices, a wide variety of angles of use can be generated. Typically a digit-looped device locks the digits and hand into a single orientation that can only function comfortably across a limited range of angles. Both in angles distal or away from the user and oblique angles or angles acutely to the side of the user, devices with digit loops move beyond their effective comfort range and promote hand stress and fatigue. This stress and discomfort is the result of creating unnatural hand postures. These hand postures can create severe wrist adduction or flexion causing discomfort and a loss of strength or leverage to operate the device. In certain instruments such as instruments used for minimally invasive or laparoscopic dissection, a surgeon may operate a looped device for long periods of time, across a wide range of angles.
- In other conventional instruments, the handle comprises two holes for insertion of middle digit in one ring and digit in the other ring. The sizes of these rings are often small and not optimized for all types of hand sizes. This method in which the whole instrument is supported by only a thumb and finger and in which case, the hand and wrists make a very awkward and unnatural angle with respect to the angle of use is often very cumbersome to the surgeon and extended use of instrument in this position causes severe fatigue and hand pain. This results in painful situations during extended surgeries.
- Accordingly, a need remains for an ergonomic medical instrument handle to overcome at least one of the above-noted shortcomings. The non-limiting exemplary embodiment(s) satisfies such a need by providing an ergonomic medical instrument handle that is convenient and easy to use, lightweight yet durable in design, versatile in its applications, and designed for easily and conveniently enabling a user to articulate his/her digit while operating the medical instrument handle and thereby reduce fatigue and discomfort during extended medical procedures.
- In view of the foregoing background, it is therefore an object of the non-limiting exemplary embodiment(s) to provide an ergonomic multi-functional handle used to manipulate a medical instrument such as an electrosurgical, monopolar, laparoscopic instrument, for example, while reducing user fatigue. These and other objects, features, and advantages of the non-limiting exemplary embodiment(s) are provided by a multi-functional handle for manipulating a medical instrument. Such a multi-functional handle includes a body capable of being gripped by a hand of a user and capable of being in communication with a medical instrument. Such a body includes a first portion and a second portion coupled thereto such that the second portion is displaced relative to the first portion. In this manner, one of the first portion and the second portion is capable of manipulating the medical instrument.
- In a non-limiting exemplary embodiment, the multi-functional handle further includes a first trigger assembly. Such a first trigger assembly preferably includes an actuation arm, and a primary digit-receiving member coupled to the actuation arm. The first trigger assembly is pivotally coupled to the body in such a manner that the actuation arm is capable of actuating the medical instrument independently from movement of the primary digit-receiving member. In this manner, the primary digit-receiving member is selectively displaced between alternate orientations relative to a position of the body and relative to a position of the actuation arm, respectively.
- In a non-limiting exemplary embodiment, when each of the first portion, second portion and first trigger assembly are present, both the first trigger assembly as well as one of the first portion and second portion operates the medical instrument.
- In a non-limiting exemplary embodiment, when each of the first portion, second portion and first trigger assembly are present, either the first trigger assembly operates the medical instrument or one of the first portion and second portion operates the medical instrument.
- In a non-limiting exemplary embodiment, the primary digit-receiving member is selectively displaced between alternate orientations relative to a position of the body and relative to a position of the actuation arm, respectively.
- In a non-limiting exemplary embodiment, the primary digit-receiving member is linearly reciprocated along a linear travel path extending outwardly from a proximal end of the actuation arm.
- In a non-limiting exemplary embodiment, the primary digit-receiving member is freely articulated about an x-axis, y-axis and z-axis.
- In a non-limiting exemplary embodiment, the multi-functional handle further includes a secondary digit-receiving member attached to the body.
- In a non-limiting exemplary embodiment, the secondary digit-receiving member is fixedly coupled to the body.
- In a non-limiting exemplary embodiment, the multi-functional handle further includes a tertiary digit-supporting member attached to the body.
- In a non-limiting exemplary embodiment, the tertiary digit-supporting member is fixedly coupled to the body.
- In a non-limiting exemplary embodiment, the tertiary digit-supporting member is pivotally coupled to the body.
- In a non-limiting exemplary embodiment, the tertiary digit-supporting member is pivotally coupled to the second portion and extends proximally away therefrom.
- In a non-limiting exemplary embodiment, the tertiary digit-supporting member is resiliently coupled to the second portion thereby returning to an equilibrium position after being biased to an offset position.
- The present disclosure further includes a method of utilizing a multi-functional handle for manipulating a medical instrument. Such a method includes the steps of: obtaining and gripping a body in a hand of a user wherein the body includes a first portion and a second portion coupled thereto; and displacing the second portion relative to the first portion such that one of the first portion and the second portion manipulates a medical instrument.

Such a method includes the steps of: obtaining and gripping abody 150 in a hand of a user wherein thebody 150 includes a first portion 151 and a second portion 152 coupled thereto; and displacing the second portion 152 relative to the first portion 151 such that one of the first portion 151 and the second portion 152 manipulates amedical instrument 180. - In a non-limiting exemplary embodiment, as perhaps best shown in
FIGS. 1 and 14 , thefirst trigger assembly 120 is operatively coupled to the medical instrument 180 (e.g., laparoscopic tool 180). Themedical instrument 180 includes arectilinear drive rod 113 having a proximal end operatively coupled to thehandle 100, as will be explained in more detail hereinbelow. A distal end of thedrive rod 113 contains alinkage assembly 111 operatively coupled to aconventional jaw assembly 104. One skilled in the art understands the conventional operation of such components. Thelinkage assembly 111 includes afirst link lever 163 and asecond link lever 169 pivotally coupled to opposite sides of the distal end of thedrive rod 113. Manipulation of thedrive rod 113—viafirst trigger assembly 120—causes articulated of the first and second link levers 163, 169 about acommon fulcrum axis 162 at the distal end of thedrive rod 113. Such first and second link levers 163, 169 are also pivotally coupled tofirst jaw 166 andsecond jaw 167, atjoints second jaws jaw pin 165. In this manner, when the distal end of thedrive rod 113 is linearly urged—alongdistance 161—towards the first andsecond jaws longitudinal axis 190 of thedrive rod 113. Such pivotal movement urges apart the first andsecond jaws drive rod 113—alongdistance 161—away from thejaw pin 165 causes the first and second link levers 163, 169 to articulate towards thelongitudinal axis 190 of thedrive rod 113 and thereby articulate the first andsecond jaws - Referring to
FIG. 2 , in a non-limiting exemplary embodiment, a partially exposed side elevational view illustrating the interrelationship between the internal components of themulti-functional handle 100 shown inFIG. 1 , is disclosed. Thefirst trigger assembly 120 operates themedical instrument 180 wherein therectilinear drive rod 113 is housed within theshaft 103. A proximal end of thedrive rod 113 is attached to a distal end of theactuation arm 129. Such adrive rod 113 may be connected to theactuation arm 129 via a ball/socket joint drive rod 113 along alinear travel path 161 defined parallel to thelongitudinal axis 190 of the shaft 103 (as perhaps best shown inFIG. 14 ).FIGS. 6 and 8 illustrate the drive rod ball joint 128 andactuation arm 129ball socket 142. Articulation of thefirst trigger assembly 120 is effectuated by manual manipulation of theactuation arm 129 along the arcuate path illustrated by thearrow 112. Connection between theactuation arm 129 and driverod 113 is spaced from thefirst pivot axis 126 about which thefirst trigger assembly 120 pivots. A rotation knob joint 105 is attached to thedrive rod 113 at a distal location of thebody 150 so that themedical instrument 180 can be selectively articulated via rotation of theactuation arm 129 at a proximal end of thebody 150. Of course, alternately, the position of theactuation arm 129 may be located at a distal end ofbody 150. - Referring to
FIG. 2 , in a non-limiting exemplary embodiment, an electrical current may be supplied to themedical instrument 180 via a high-frequency (HF)connector plug 107 extending outwardly and away from a top of thebody 150. AHF connector lead 106 is communicatively coupled to theconnector plug 107 and travels downward into a hollow cavity of thebody 150 wherein it maintains electrical communication with thedrive rod 113. - In a non-limiting exemplary embodiment, an energy source such as a tissue-altering energy source may be communicatively coupled to the
handle 100. Exemplary tissue-altering energy sources may generate a heat signal, acoustic signal, microwave signal, light signal, etc., as well-understood by one of ordinary skill in the art. Each tissue-altering energy source may include different components for interfacing with thebody 150 and/or themedical instrument 180. Thus, theHF connector plug 107 and lead 106 are not a necessity and are merely provided as an illustrative example; not restrictive. - Referring to
FIG. 3 , in a non-limiting exemplary embodiment, an enlarged view of thesecond trigger assembly 130, taken inFIG. 2 , is disclosed. As noted above, thesecond trigger assembly 130 permits selective articulation of a portion—actuation arm 129—of thefirst trigger assembly 120 along thearcuate path 112 for manipulating the medical instrument 180 (e.g., jaws). Of course, one skilled in the art understands a variety ofmedical instruments 180 may be manipulated by movement of thefirst trigger assembly 120. - In a non-limiting exemplary embodiment, the
second trigger assembly 130 is employed to selectively lock theactuation arm 129 at alternate positions, as desired. Thus, while thefirst trigger assembly 120 permits operation of themedical instrument 180, thesecond trigger assembly 130 enables the user to lock thefirst trigger assembly 120 at a desired position thereby preventing further manipulation of themedical instrument 180. - In a non-limiting exemplary embodiment, as perhaps best shown in
FIGS. 3, 4 and 7 , thesecond trigger assembly 130 preferably includes aratchet cam shaft 119 formed at thesecond pivot axis 127. Aratchet trigger 153 is statically coupled to theratchet cam shaft 119 and is disposed exterior of thebody 150. Theratchet trigger 153 pivots about thesecond pivot axis 127 thereby causing a ratchetcam shaft arm 116 to articulate in a corresponding direction. For example, when theratchet trigger 153 is rotated clockwise, the ratchetcam shaft arm 116 also rotates clockwise; and visa-versa. - In a non-limiting exemplary embodiment, a ratchet cam shaft snap fit 117 is formed at an end of the ratchet
cam shaft arm 116 and locks to a snap fit anchor bracket 117 statically housed within thebody 150. For example, the snap fit anchor bracket 117 may be friction locked, magnetically locked, or locked via other suitably ways, without departing from the true spirit and scope of the present disclosure. Aratchet pawl cam 121 is statically mated to theratchet cam shaft 119 and remains angled away from the ratchetcam shaft arm 116 such that it selectively displaces one end of aratchet pawl 122. Theratchet pawl 122 has an opposite end anchored to a ratchetpawl attachment boss 123 located distally of thefirst pivot axis 126. In this manner, articulation ofratchet trigger 153 along a first rotational direction causesratchet pawl cam 121 to urgeratchet pawl 122 towards aratchet arm 147 having a serrated surface. A proximal end of theratchet pawl 122 engages theratchet arm 147teeth 118 and the ratchet cam shaft snap fit 117 locks theratchet trigger 153 at a locked position. Such cooperation between theratchet pawl 122,ratchet arm 147 and ratchet cam snap fit 117 prohibit premature or undesirable movement of theratchet trigger 153, thereby maintaining themedical instrument 180 at a desired orientation. - In a non-limiting exemplary embodiment, rotation of
ratchet trigger 153 in an opposite direction releases the ratchet cam snap fit 117 and disengages theratchet pawl 122 from theratchet arm 147. Such disengagement permits theratchet arm 147 to articulate in sync with theactuation arm 129 of thefirst trigger assembly 120 thereby permitting manipulation of themedical instrument 180 as desired. - In a non-limiting exemplary embodiment,
FIG. 4 illustrates an enlarged side elevational view of themulti-functional handle 100 for articulation of thefirst trigger assembly 120 about thefirst pivot axis 126. During manipulation of themedical instrument 180, thefirst trigger assembly 120 articulates about thefirst pivot axis 126 and along a firstarcuate path 112 while theratchet trigger 153 is at a lowered position (e.g., unlocked position). To prohibit manipulation of themedical instrument 180, theratchet trigger 153 articulates along a secondarcuate travel path 124, and about asecond pivot axis 127 offset from thefirst pivot axis 126. When theratchet trigger 153 is articulated to a raised position (e.g., locked position), theactuation arm 129 is prohibited from rotating along thearcuate path 112. As noted herein above, raised/lowered positions maybe first/second positions and visa-versa. - In a non-limiting exemplary embodiment,
FIGS. 5 and 6 are cross-sectional views showing the interrelationship between thefirst trigger assembly 120,second trigger assembly 130 andthird trigger assembly 140.FIG. 8 is an enlarged perspective view illustrating the interrelationship between thethird trigger assembly 140 and theactuation arm 129.FIG. 9 is an enlarged perspective view illustrating the receivingaperture 146 of the primary digit-receivingmember 131. With reference toFIGS. 5-6 and 8-9 , the digit locking switch is referred to as thethird trigger assembly 140. Such a mechanism permits selective movement of the primary digit-receivingmember 131, which may be a loop, for example. Of course, the primary digit-receivingmember 131 may be a variety of shapes and should not be construed as limited to only a loop shape. - In a non-limiting exemplary embodiment, the
third trigger assembly 140 is operably coupled to theactuation arm 129 and primary digit-receivingmember 131 of thefirst trigger assembly 120. Thethird trigger assembly 140 includes aswitch 149 that is linearly reciprocated along aslot 145 formed in theactuation arm 129. Theswitch 149 is partially inserted into theactuation arm 129 and has aswitch follower 133 statically mated thereto. A switch snapfit arm 134 extends downwardly and distally from theswitch follower 133, traveling along apath 141 aligned substantially parallel to the reciprocating motion of theswitch 149 above. A switch snap fit 135 is formed at a distal end ofswitch arm 134.Grooves actuation arm 129.Such grooves linear path 141 wherein, when the switch snap fit 135 is positioned in aproximal groove 137, theswitch arm 134 is locked and prohibited from movement. When the switch snap fit 135 is slidably inserted in thedistal groove 138, a lockingshaft 132 is displaced outwardly from a receivingaperture 146 thereby permitting movement of the primary digit-receivingmember 131. Although, the lockingshaft 132 has a hexagonal shape with a corresponding hexagonally shaped receivingaperture 146, any number of interlocking shapes may be used to prohibit movement of primary digit-receivingmember 131. The primary digit-receivingmember 131 is coupled to theactuation arm 129 via a joint for maintaining the receivingaperture 146 within theactuation arm 129 during movement of the primary digit-receivingmember 131; prevents primary digit-receivingmember 131 from disengaging the lockingshaft 132. - In a non-limiting exemplary embodiment, with reference to
FIGS. 4 and 7 , an enlarged perspective view illustrating articulation of theratchet arm 153 about thesecond pivot axis 127 is disclosed. Also, areference line 191 is shown passing through the secondary digit-receivingmembers body 150.
