Description

Surgical Staple Extractor

1 to 6 are a right side view, left side view, back view, front view, top view and bottom view of the staple extractor of the present invention, respectively.

7 and 8 are right side and top views, respectively, of the first extractor arm.

9 and 10 are right side and top views, respectively, of the second extractor arm.

The present invention relates to a staple extractor, and more particularly, to a staple extractor for extracting a surgical staple from the skin or fascia.

The staple extractor of the present invention has advantages over the devices according to the prior art. One advantage depends on the distal end of the first extractor arm, which distal end is essentially rounded, so that the distal end of the first extractor arm can be easily placed under the staple to be removed. "Shovel-like effects" are provided.

Another advantage is that in disposition of the instrument and / or removal of the staples its distal end does not stab or stab the skin or fascia. Another advantage is that the first extractor arm can be made integral with its distal end. Thus, the possibility of breaking or bending the distal end, for example by dropping the instrument, is reduced or eliminated. In addition, the strength of the distal end is uniform, so that a portion of the distal end is weakened, thereby reducing or eliminating the possibility of causing malfunction of the apparatus in use. This advantage is essential in surgical operations where time and precision are paramount.

Another advantage resides in connecting means which allow the index finger or middle finger to rest on the connecting means. Yet another advantage is that the first handle means are angled towards the second handle means. Thus, the magnitude of the pressing and expanding movement by the handle means is reduced. This reduction eliminates the need for using spring means for expansion operation.

Another advantage of the instrument is that the shape of the first and second handle means is elliptical. This shape can be distributed over a wide area of compression and expansion force. Thus, it can be more comfortable for the user when the appliance is used for a long time.

The staple extractor of the present invention has a first extractor arm having a rounded end portion and a slot, a second extractor arm having a molding member formed at the distal end portion, and a means for connecting the arms. First and second handle means are formed which are partially or completely enclosed at the inner shaft ends of the first and second arms so that the handle means cooperate to drive the shaping means into the slot.

According to another embodiment of the present invention, in the above-described mechanism, the length from the connecting means to the first handle means is determined such that the index finger or the middle finger can be placed on the connecting means, and the first handle means is the second handle means. Angled toward, the first handle means are elliptical, the thumb can be disposed diagonally to the first handle means, the second handle means are elliptical, ring finger and pinky, or middle finger and The ring finger comprises staple extractors, which can be disposed perpendicular to the second handle means.

According to yet another embodiment, the staple extractor described above has a bend in contact with the second handle means and a middle finger can be placed on the bend.

The staple extractor of the present invention will be described in detail below by gluing the accompanying drawings.

In FIGS. 1 to 6, the device of the present invention has a first extractor arm 1, and in FIGS. 7 and 8, the distal end 1a of the first extractor arm is rounded and slotted. It can be seen that it has the track 1b. Furthermore, in FIGS. 1-6, the apparatus of the present invention has a second extractor arm and a second extractor arm 2, and in FIGS. 9 and 10 the distal end of the second extractor arm ( It can be seen that 2a) has a molding member 2b.

Again, in FIGS. 1-6, first and second handle means 1c and 2c are formed at the inner ends of the first and second extractor arms, respectively, and the means 3 are Connect the first extractor arm. The connecting means can be for example rivets or nuts and bolts.

This staple extractor is used by actuating the first and / or second handle means. The distal end 1a of the first extractor arm 1 is disposed below the staple. During the pressing operation, the shaping portion 2b of the handle second kicking arm 2 is driven into the slot 1b of the first extractor arm 1. In the expanding operation, the grip means lifts the forming member 2b out of the slot 1b so that the staples are bent and extracted during the pressing operation.

In FIGS. 1 and 2, the first and second extractor arms 1 and 2 are shown with parts separated from the first and second handle means 1c and 2c. However, it will be appreciated that either or both of the extractor arms may be manufactured integrally with the handle means. Suitable materials for making either or both of the extractor arms and / or handle means are, for example, stainless steel. Preferably, the extractor arms are made of metallic material and the handle means are made of synthetic polymer material. Suitable synthetic polymeric materials for making either or both of the handle means are, for example, acrylonitrile, butadiene, and styrene copolymers.

Methods of making this apparatus are known in the art. Methods of making extractor means and / or handle means are also known in the art and can be, for example, die stamping and molding of metallic materials and injection molding of polymeric materials.

The distal ends 1a and 2a (shown in FIGS. 7 and 10) of the first and second extractor arms 1 and 2 in FIGS. 1 and 2 understand the staple extractor. Has been shown for. The distal ends need not be shown in actual size in relation to each other, so that the forming member 2b (shown in FIG. 9) can be seen in FIGS. 1 and 2 if the distal ends are shown in actual size. . 1, 2 and 7-10, the first and second extractor arms 1 and 2 are separate from the first and second handle means 1c and 2c. The parts are shown. In this example, the extractor arms have tabs and the handle means have slots. Each extractor arm tab is disposed in a respective handle means slot. Next, means 3, which may be, for example, Tibet or nuts and bolts, connect the first and second extractor arms. The tabs and slots may be tapered as shown in FIGS. 1 and 2 to assist in placing each tab in a respective slot.

Also in this example and in FIGS. 8 and 10, the respective extractor arm tabs are biased from the distal ends of the first and second extractor arms. The individual knitted tabs offer high manufacturing precision and high usage accuracy.
