12 Claims.
This invention relates to adjustable angle surgical instruments. Although adapted to many general iields of use, it is particularly useful in the fields of surgery, dentistry, and the like.
5 One object of this invention is to facilitate access to regions which are diicult to reach with ordinary instruments.
Another object is a multi-angle surgical instrument which can be adjusted to different angular positions as circumstances may require.
Another object is to simplify and expedite surgical operations.
Another object is a surgical instrument which can be used without obstructing the eld of operation.
Other objects will appear from the detailed description which follows.
In the drawings comprising two sheets of nine figures numbered-Figs. l to 9 inclusive: 20 Fig. 1 is a view of a torso partially broken away to show one adaptation of my adjustable angle surgical instrument used as a grasping instrument.
Fig. 2 is a front view illustrative of one form of surgical instrument embodying my invention.
Fig. 3 is a view of the said instrument in open position.
Fig. 4 is a side view of the instrument.
Fig. 5 is a front View of a portion of the mechanism with certain of the parts shown in section.
Fig. 6 is a side View of the device of Fig. 5.
Fig. 7 is a vertical sectional view taken along the line 'l-T of Figure 5 looking in the direction of the arrows.
Fig. 8 is a front view of a modified form showing certain of the parts in section; and
Fig. 9 is a horizontal cross section taken along the line 9 9 of Figure 8 looking in the direction of the arrows.
Like reference characters designate corresponding parts throughout the several gures of the drawings.
Referring to Fig. 1 an incision 2| has been made in a torso 20, and an instrument 23 embodying my invention adjusted to the desired angle, has been inserted through said incision to grasp and retain the organ 22 in fixed position. It should be observed that the instrument 23 has been so adjusted, that the handles thereof are supported upon the torso without obstructing the field of operation.
Referring to Figs. 2 to 4 inclusive, instrument 23 includes the operating jaws 24 and 25, of (merely by way of illustration) a grasping, holding or clamping instrument, such as a pair of (Cl. 12S-321) forceps or the like. The particular form of jaws employed forms no part of this invention, any other form of jaws may be substituted in the instrument23 dependent upon the particular use intended. As a surgical instrument the device has particular reference to all forms and kinds of grasping, holding, carrying, crushing, cutting or clamping instruments, such as forceps, clamps, hemostats, tenaculums, ronguers, carriers, scissors, and some of the special instruments such as gall bladder forceps, intestinal forceps, and nose and throat instruments. The device may also be applied to dental and veterinarian instruments.
To lock operating jaws 24-25 at any selected angle relative to handles MJ-M, one lever arm 33 is provided with a notched plate 2l (Figs. 4 and 6), and the associated arm 32 is provided with a locking pin 28 adapted to engage in the various notche's of notched plate 21. To facilitate centering of pin 28 in plate 2l, the pin may be tapered, and the notches of plate 21 may be bevelled (see Fig. 5). The jaws 24--25 close against the increased tension of the hook shaped spring 3|. Spring 3l is held in position upon the arm 32 by screw 29, and said spring is provided with ears 30-39 engaging around the front and rear walls of the arms 32-32 to pre-1 vent lateral movement of the spring. Each lever arm 33 is provided with an opening 36 to permit the insertion of a screw-driver or like article in the notched ball headed screw 34, .so that the several parts can be easily mounted and adjusted. Handle members All-4| are provided With spur ratchet bars 42-43 which engage as the handle members l0-4! are moved from the open position (Fig. 3) towards the closed position (Fig. 2), to adjustably lock operating jaws 2d and 25 by way of arms 32-32, lever arms 33-33, 55
Cil
and handle members 40-4I in the closed, graspi ing, holding or clamping position shown in Figs. 1 and 2.
To adjust instrument 23 to any desired angle, the handle members lll-40 are moved apart (Fig. 3), until locking pin 28 disengages notched plate 21; operating jaws 24e-25 are now turned about the universal joint formed by ball headed screws 34-34 and their associated ball sockets 35-35 to any desired angle (as for example, the position indicated in dotted outline in Fig. 4), whereupon the handle members 4 l-40 are movedinwards against the increased tension of hook spring 3|, until tapered locking pin 28 re-engages in one of the bevelled notches of notched plate 21, thereby locking jaw members 24 and 25 at the selected angle relative to lever arms 33-33 and handle members 4|-40. The number of angular Settings will be governed by the number of notches provided in notched plate 21. Notched plate 21 and locking pin 28 illustrate one convenient form of angle setting and locking device. Many alternative forms of angle setting and locking device will occur to those skilled in the art.
In the modified form illustrated in Figs. Sand 9 locking pin 28 and notched plate 21 are dispensed with, and knurled ball screws 44-45 are substituted for the ball headed screws 34-34 of the device of Fig. 5. With this construction with handle members lli-4I in open position the operating jaws 24-25 are turned to the desired angle about the universal joint formed by knurled screws 44--45 and their associated ball sockets. Applying slight gripping pressure on the handle members 40 and 4|, causes the knurled surfaces of the ball screws to frictionally engage the walls of their associated sockets to lock the arms 32-32 relative to the lever arms 33-33 at the desired angle.
The use of this multi-angle instrument will facilitate many surgical procedures, especially where structures, organs, tissues, blood vessels, or nerves, are difficult to reach with ordinary instruments. Its use likewise eliminates delay and expedites operative procedure in cases where a fixed angle instrument has not been sterilized, and is therefore not available for immediate use when unexpectedly needed. This multi-angle instrument is also a great advantage in those cases where the surgeon requires an instrument having a particular angle for picking up a structure, and an instrument having an entirely different angle for holding the structure while the operative procedure is completed. In such circumstances my multi-angle instrument is invaluable because the angle of the instrument can be changed immediately and the handle members 4l-40 moved to that position which eliminates obstruction of (or least obstructs) the surgeons eld of operation.
