Definitions
- the invention relates to a pair of pliers referred to in the preamble of claim 1 Art.
- DE 195 21 257 AI shows a generic pliers with a cam engaging with a groove which is arranged at a greater inclination angle relative to the displacement direction of the actuating rod.
- the Nuteingriff can hereby transmit movements in both directions. Due to the large angle of the groove relative to the direction of displacement, there is no self-locking. Because of the large angle large changes in angle of the moving jaw part can be effected quickly.
- a disadvantage of this known construction is that closing forces to be applied by the forceps jaw, for example when using a needle holder, the clamping force must constantly be maintained by applying an actuating force via the actuating rod when holding the needle.
- the object of the present invention is to make a generic pliers easier to use. This object is achieved with the features of the characterizing part of claim 1.
- the angle of inclination of the groove is at least in a partial region below the angle up to the self-locking exists. If the cam is located in this portion of the groove, so there is self-locking. This means that a movement in the groove is possible upon actuation of the actuating rod, but not in the opposite way when moving the jaw member. It can therefore be acted on the actuating rod on the moving jaw part, but not in the opposite direction, since there is self-locking for this direction.
- the self-locking ensures that after clamping an object in the forceps jaw by pressing the operating rod, the clamping position is maintained even when the operating rod is released. The self-locking thus results in a locking of the pliers wall in the clamping state. This means z.
- the operating handle can be released, while maintaining the clamping position in which the needle is held securely.
- the angle of inclination to which self-locking occurs is a few degrees, depending on the coefficients of friction of the materials used.
- the groove can be self-locking over its entire length.
- the second end region can thus be moved with smaller translation, the forceps jaw over larger angular ranges quickly.
- the kinematics of the pliers is to choose so that when clamped object, z. B. with held needle, the cam actually enters the self-locking first end.
- a spring for cushioning the actuating force is advantageous in surgical forceps when it is to be locked in the gripping position.
- the spring may maintain the closing force, even if the gripped object, e.g. Tissue, continually yielding, e.g. shrinks in electrocoagulation.
- such a spring can maintain the force of gripping a rigid body when the forceps are used, for example, as a needle holder.
- the actuating force is transmitted continuously by the actuating rod.
- the spring can therefore be arranged in the handle.
- such a spring is advantageously arranged in the forceps jaw and can maintain the actuating force there when the forceps jaw is locked in itself by the engagement of the cam with the first end region of the groove.
- one of the jaw parts can be designed to be resiliently yielding.
- the forceps jaw is rotatably mounted relative to the actuating handle, whereby the application possibilities of the forceps are improved.
- a particularly advantageous rotary control from the actuating handle ago takes place, according to claim 6, via the actuating rod, whereby the construction is simplified.
- the shank of the forceps is bent according to claim 7 in the pliers according to the invention.
- Such a bent shaft facilitates handling of the forceps during minimally invasive surgical procedures.
- Fig. 1 is a side view of a pliers according to the invention.
- FIG. 2 is a partially cutaway, enlarged view of the distal end portion of the forceps of FIG .. 1
- the forceps 1 shown in side view in FIG. 1 is designed in particular for laparoscopic use. It has an elongated, curved shaft 2, at the distal end of a forceps jaw 3 and at the proximal end of an operating handle 4 are arranged.
- the forceps jaw 3 has two jaw parts, of which one jaw part 5 fixed and the other jaw part 6 is pivotally mounted on the shaft 2.
- the operating handle 4 has a main body 7, on which two finger grips 8, 9, respectively, as shown, with handle ring, about an axis 10, are stored. On the main body 7, a rotary ring 11 is also mounted.
- the shaft 2 is cut as a tube. It is, as the sectional view shows, rotatably mounted with a pivot bearing 12 on the proximal end portion of the stationary jaw part 5.
- the stationary jaw part 5 extends from the pivot bearing 12 to its distal end, where it is designed as a gripping jaw 13, which is connected via a weakened, resilient point 14, with the remaining part of the jaw part 5.
- an axle pin 15 is further attached, on which the pivotable jaw part 6 is pivotally mounted, which is also formed in its distal end portion as a gripping jaw 16.
- an actuating rod 17 is mounted longitudinally displaceable, which is connected at its proximal end, not shown in the main body 7 of the operating handle 4, upon actuation of the finger grips 8, 9, longitudinally adjustable.
- the actuating rod 17 is rotatably mounted with a polygonal region 24, but longitudinally displaceable in the proximal end region of the stationary jaw part 5.
- the actuating rod 17 is further rotationally coupled in a manner not shown with the rotary ring 11 longitudinally.
- a cam 18 is fixed, which runs in a groove 19 which is formed in the pivotable jaw part 6.
- the groove 19 has a first end portion 21 and a second end portion 22.
- the first end portion 21 extends in the direction of the dashed oblique line S, which, as shown in FIG. 2, is at a very small angle, the inclination angle, obliquely to the direction of displacement V of the actuating rod 17.
- the second end region 22 of the groove 19, as shown in FIG. 2 has a very large inclination angle.
- the kinematics of the pliers shown in Fig. 2 is such that upon retraction of the actuating rod 17 in the direction of the arrow PI, the gripping jaw 16 is pivoted in the direction of the arrow P2 against the fixed gripping jaw 13. In this case, initially takes place during movement of the cam 18 within the second end portion 22, a fast pivoting with little force. Upon further retraction of the actuating rod 17 of the cam 18 enters the first end portion 21 and now causes very low pivoting movements, but at high power transmission.
- the forceps 1 is particularly suitable as a needle holder in order to be able to hold a needle 23 between the gripping jaws 13 and 16 with high force.
- the pliers 1 is in the formation of the gripping jaws 13 and 16 so constructed that when holding the needle 23, in the manner shown in Fig. 2, the groove 18 can enter the first end portion 21, as shown in Fig. 2nd is shown.
- the needle 23 can then be held with high force between the jaws 13 and 16, wherein on the actuating rod 17 only a very small force is needed.
- the angle of inclination of the groove 19 in the first end region 21 may also be zero. Then, when holding with high force gripping jaws 13 and 16, the actuating rod 17 can be completely free of force. In force-free, or loaded with only low closing force, actuating rod 17, the pivot bearing 12 is free of longitudinal loads that would hinder its free rotation. The forceps jaw 3 can therefore be rotated very easily even under high gripping forces, which is very useful when a firmly held needle 23 is to be pivoted into a specific sewing position.
- the inclination angle between the dashed lines S and V that is, between the direction of the first end portion 21 of the groove 19 and the displacement direction of the operating rod 17, is very small, as shown in FIG. He is chosen so that it acts self-locking, so that the cam 18 when it is pulled by retracting the actuating rod 17 in the first end portion 21, there clamps and prevents even completely unloaded actuating rod 17, an automatic opening of the forceps muzzle 3.
- a spring in which the forceps jaw 3 is blocked by self-locking in itself, such a spring must be provided in the jaw part.
- one of the two jaw parts namely the stationary jaw part 5
- the spring 14 which in the exemplary embodiment is designed as a weakening point between the jaw part 5 and its grip jaw 13.
- the spring can also be designed simply as a resilient compliance of one of the jaw parts.
- the jaw part 5 is fixed and the jaw part 6 is pivotable about the axle pin 15.
- it can also be a construction with two pivotable jaw parts are used.
