ABSTRACT
An improved surgical ligating instrument has been invented. The improved instrument comprises a housing in substantial parallel alignment with a clip loading, advancing and crimping means.
Description
~17~ 3C~
This invention relates to an improved surgical ligating instrument.
The surgical ligating instrument of this invention has advantages over the prior art. One advantage is the housing which is in substantial parallel alignment with the probe. In this alignment, a high degree of accuracy can be obtained in the use of the instrument. For example, the orientation of the probe is in the same plane as the motion of the user's hand.
Another advantage is the compactness of the housing.
10 A predominant portion of the housing can be easily held by the palm of a hand. This can be most important in internal surgery, for example in a body cavity, where the compactness and/or narrow-ness of the instrument may enable the surgeon to have a higher degree of control.
Yet another advantage is the "pointing" of the fingers as the hand grips the instrument. Specifically, a thumb and at least an index finger form a pointed profile as the hand grips the instrument. The pointing has a streamline effect which can allow the user to place the instrument as deeply as possible into a body cavity.
Still another advantage of the instrument is in the upper portion of the housing and first activating means (for example a trigger) which are in diagonal alignment with the probe.
A diagonal alignment of the housing upper portion and trigger seems to counteract the optical and manual illusion that the probe is nonparallel with the housing.
,. - 1 - #
3~L d ~30 A diagonal alignment may also better conform to the contour of the hand.
Still yet another advantage is the erimping motion of the jaws whieh can be substantially parallel to the compression motion of the first and the second activating means. The motion of the jaws can therefore be an extension of the squeezing motion of the user's hand. The hand/eye (more formally termed the visual/tactile) coordination of the user is therefore increased and may even be maximized. Further, another advantage is a rest-ing area for the index finger. The resting can allow the index finger to be used as a reaction force against the first activating means being compressed by the thumb. Also, the resting area can allow the index finger to have more accuracy--guiding the instru-ment.
Finally, another advantage is the location of the second activating means. The location can allow a strong eompressive force to be applied by the index and/or middle finger. Since either or both of these fingers tend to be the strongest, the efficiency in the use of the instrumen~ is increased and may even be maximized.
The invention accordingly provides a surgical ligating instrument having a housing eontaining a first and a second force activating means; and elip loading, advaneing and erimping means, the improvement eomprising said housing in substantial parallel alignment in at least two planes with said loading, advancing and crimping means; and said first and second activating means are compressible into said housing, wherein an independent force ean be applied to each of said first and second activating means only ~-~?

in compression.
One embodiment of the instrument is wherein a predominant portion of said housing can be essentially held by the palm of a hand; and wherein said first and second force activating means can be operated respectively by a thumb, and by at least one finger in a nonextended position.
Another embodiment of the instrument is wherein said loading, advancing and crimping means are contained in a probe, the terminal end of said probe containing jaws; wherein said first and second activating means are in opposing relationship and adja-cent said probe; and wherein a thumb - 2a -~ ,3~
is placed on said first activating means and at least an index finger is placed on said second activating means such that said thumb, and at least said index finger form a pointed profile.
Still another embodiment of the instrument is wherein said housing has a curved portion between said second activating means and said probe; wherein an index finger is placed on said curved portion; and wherein a thumb is placed on said first activating means and at least 10 a middle finger is placed on said second activating means such that said thumb, said index finger and at least said middle finger form a pointed profile.
A further embodiment of the instrument is wherein the crimping motion of said jaws is substantially parallel 15 to the compression motion of said first and second activa-ting means.

DETAILED DESCRIPTION
Referring to Figures 2 and 5 to 7, the surgical ligating instrument has a housing 30. The housing contains a first acti-vating means, for example a trigger 1, and a second activating means, for example a handle 17. The housing can internally contain a first and a second force translating means (not shown), for example as described in Canadian Application Serial No. 392,342 filed December 15th, 1981. The first and the second force trans-lating means is activated by the trigger l and the handle 17, respectively.
Referring to Figures l, 2 and 8, the instrument has a probe 31. The probe can internally contain a clip loading, advanc-ing and crimping means for example as described in the above-identified application. Preferably, the initial end of the load-ing, advancing and crimping means is contained in the housing 30.
The housing 30 is in substantial parallel alignment with the probe 31. Preferably, the first activating means l and the upper portion of the housing are in a diagonal alignment with the probe 31. A diagonal alignment seems to counteract the optical and manual illusion that the probe is nonparallel with the housing and may better conform to the contour of the hand.
Preferably, the size of the housing is such that a predominant portion of the housing can be essentially held by the palm of a hand.
The terminal end of the probe 31 contains jaws 23.
Referring to Figure 2, in one embodiment the housing has a curved portion 30a between the second activating means 17 and the probe 31. An index finger can be placed on the curved portion.
1~'7~ 0 Figures 5 to 7 are alternative embodiments of the surgical instrument housing shown in Figures 1 to 4.
- 4a -'~iL t ~
The description of the housing of Figures 1 to 4 essenti.ally corresponds to Figures. 5 to 7.
Figure 8 descri~es in more detail the probe 31.
The optional raised portion 31a can be a transparent material and is adjacent to the inital end (.not shown) of the jaws 23 in the probe. The raised portion gives a visual identification to the user that clips are/are not remaining in the instrument.
Referring to Figures 1 to 6ascalloped configuration in the upper portion of the housing and the first activating means and in the lower portion of second activating means is preferred. The scalloping assists the user to grip the housing and to compre~s the first and the second activating means. The partial and broken scalloping shown in Figures. 1 to 3 are for clarity of illustration.
It is to be understood that the scalloping in Figures 1 and 3 is cons.istent with Figure 2. It is also to be under stood that the probe shown in Figure 2 is identical in Figures 5 to 7. A notch 30b between the first activating means and the upper portion of the housing, and a notah 30c between the second activating means and the lower portion of the housing reduces or may even eliminate the possibility that the hand and/or fingers of the user are punched when the first and the second activating means are returning to the relaxed position.
