Definitions

  • This present invention relates to an adapter sleeve that can be attached to a scalpel blade.
  • the adapter sleeve provides a handle that is easier to hold, thereby giving the surgeon greater control and ability to make more precise incisions.
  • the adapter sleeve of the present invention includes a cavity extending through a portion of the sleeve that receives the proximal end or handle of the scalpel such that the blade extends from the distal end of the adapter.
  • An outer surface region of the adapter sleeve includes a handle portion that is gripped manually by the hand of the user during a surgical procedure.
  • the sleeve handle has a contoured surface to provide for proper orientation of the blade of the scalpel relative to the surgical site.
  • the contoured surface of the handle can include a proximal section with a thicker diameter that tapers to a smaller diameter section at the distal end.
  • the distal section can have a recess for the thumb of the user.
  • the blade can be rigidly oriented relative to the surface features to improve manual manipulation.
  • the sleeve handle can be left or right handed.
  • the method for using the adapter sleeve of the present invention involves selecting a blade, inserting it into the adapter, performing the selected procedure, removing the scalpel for cleaning, sterilization, and reuse, and either sterilizing or disposing of the adapter sleeve.
  • the scalpel blade is assembled with the adapter sleeve during manufacture.
  • the adapter sleeve in this embodiment is made of a plastic material suitable for sterilization after use.
  • the sleeve can be molded as a unitary body with selected portions of the surface having a hatched, abraided or dimpled surface to provide frictional surface regions unlikely to slip when grasped by the user.
  • the sleeve can also be molded in two pieces that snap together about the blade using a connector.
  • a preferred embodiment can also include a rotational mechanism to provide for adjustment of the angular orientation of the blade relative to the adapter handle.
  • the cavity is sized to provide for two different angular orientation of the blade edge relative to the adapter handle, thus allowing the user to select the proper orientation for a given procedure.
  • the adapter handle can have inner and outer sections or sleeves that rotate relative to each other. The user can turn the blade relative to the handle which "clicks" between selectable rotational positions to find that most suitable.
  • FIG. 1 is a front side perspective view of the adapter sleeve with a scalpel blade inserted therein in accordance with a preferred embodiment of the present invention. -A-
  • FIG. 2 is a perspective view of the proximal end of the device seen in FIG. 1 in accordance with a preferred embodiment of the present invention.
  • FIG. 3 is a perspective view of the adapter sleeve with a scalpel blade positioned for insertion at the proximal end of the adapter in accordance with a preferred embodiment of the present invention.
  • FIG. 4 is a perspective view of the proximal end of the adapter and scalpel in accordance with a preferred embodiment of the present invention.
  • FIG. 5 is a rear side view of the adapter and scalpel in accordance with a preferred embodiment of the present invention.
  • FIG. 6 is a lateral side view of the adapter sleeve and scalpel in accordance with a preferred embodiment of the present invention.
  • FIG. 7 is a cross-section view illustrating an internal cavity that receives a scalpel blade in accordance with a preferred embodiment of the present invention.
  • This invention describes an adapter sleeve that can be attached to existing flat handled scalpels.
  • the adapter sleeve can be elliptical in shape at least along a portion thereof and crosshatched or beveled to make the handle a more natural feel thereby making it easier to hold to provide superior scalpel manipulations.
  • the design can also be manufactured as a knife handle unit.
  • the adapter sleeve can be a sterilizable or disposable, elliptical-shaped, beveled plastic handle that can be used on existing scalpel handles.
  • the design of the adapter also has the advantage of making the handle less slippery than the traditional steel handle. Through use of the adapter sleeve the scalpel will be easier to manipulate thereby allowing the precision of the incision to be increased.
  • the adapter sleeve scalpel device 10 of this embodiment has a contoured handle 12 and a distally mounted blade 14 that is rigidly attached to the handle.
  • a front side of the handle 12 is shown with a recess 16 sized to receive the thumb of a user.
  • the recess can be a hatched, abraded, or provided with some other frictionally enhanced surface region 18 to improve gripping and manual manipulation of the blade.
  • FIG. 2 A rear perspective view of an adapter sleeve and scalpel is shown in FIG. 2.
  • the adapter handle has a distal portion 20, a proximal portion 22, and a lateral side 26 which has a flattened portion in this embodiment.
  • a proximal end 24 of the scalpel blade can extend from proximal portion 22.
  • the distal end 14 of scalpel 30 is inserted in direction 38 into a proximal cavity opening 36 of the adapter sleeve 32.
  • the scalpel blade slides through the cavity until the blade extends through the distal cavity or channel opening 34 of the adapter.
  • the inner cavity surface is shaped to conform to the shape of the scalpel blade to securely grip the blade during use.
  • the inner surface of the cavity can also be scalloped or dimpled to engage the frictional surface features 35 of the scalpel handle.
  • the adapter handle can be fitted with a "snap" feature that locks the scalpel handle in place upon insertion.
  • Fig. 4 shows a rear perspective view of the embodiment in Fig. 3 with the scalpel inserted into proximal opening 36.
  • FIG. 5 shows a side view in which the proximal portion 48 of adapter 40 has a circular or elliptical cross-sectional shape.
  • the front and rear sides of adapter 40 have recesses 42 and 44, respectively, that can be gripped by the thumb and fingers of the user. Additionally, one or both lateral sides can have smaller recesses 46.
  • the adapter has front and rear recesses 52 and 54, respectively, however, the lateral sides have flattened regions 56.
  • the features illustrated in Figs. 5 and 6 give the user a positive feel for how the blade of the scalpel is oriented relative to the surgical sites.
  • FIG. 7 A cross-sectional view of an adapter handle 60 is shown in Figure 7.
  • the adapter 60 is made of a soh ' d unitary element 64, in which a cavity 66 extends along a longitudinal axis 62.
  • the cavity 66 can be shaped to conform to a handle of a scalpel blade such as that shown at 30 in FIG. 3.
  • the user inserts the distal end 14 of the blade through the proximal opening 70 until the blade 14 extends through the distal opening 68.
  • the interior surface of the cavity can have a fractional surface such as ridges 65 that engage surface features 35 (FIG. 3) of the blade handle.
  • connector 72 can be used to connect the two portions together.
  • the scalpel blade has a blade section and a proximal section that mates with the internal cavity 74 shown in outline in FIG. 7.
  • the cavity does not extend through the length of the handle 64. Rather, The proximal section of the blade fits snugly within distal cavity 74 and the proximal section of the handle can be a solid material.
  • a preferred embodiment of the invention can employ the option of providing different angular orientations of the blade relative to the adapter handle.
  • the different positions can be over a continuous range of angular position 84 between 0-180 degrees, or they can be discrete.
  • the cavity can be sized in a manner allowing for two discrete angular positions in which the blade can be inserted.
  • the adapter 60 can include an outer sleeve adapter section that fits at cylindrical surface 80 relative to an inner sleeve or section that nests at cylindrical surface 82 with the outer section. The two sections rotate 84 relative to each other such that the user can adjust between angular orientations of the blade relative to the adapter.

Abstract

La présente invention concerne un manchon adaptateur fournissant une surface de préhension profilée, lequel manchon est utilisé pour maintenir une lame de scalpel pendant un acte chirurgical. Le manchon adaptateur privilégié dans cette invention peut comprendre une cavité dans laquelle la lame de scalpel peut être introduite de manière amovible pour un seul acte chirurgical. Dans un mode de réalisation alternatif, l'adaptateur peut être fabriqué sous la forme d'une unité stérilisable pourvue d'une lame de scalpel pouvant être montée de manière rigide sur une extrémité distale d'une poignée.
