Definitions
- the invention relates to a scalpel with a blade which is positively fixed on a support surface provided at the front end of a scalpel handle and when not in use is covered by a slide which is arranged to be longitudinally displaceable relative to the scalpel handle, a locking mechanism being provided between the slide and the scalpel handle by pressing or pushing the finger, the locking is released both in the protective and in the use position, into which the slide can be moved with the release of the blade. It is not possible to slide the slide out over the last step into the protective position.
- the lock also prevents the slider from being operated unintentionally.
- the slide is designed here as a protective cover which is locked on the handle during the use position of the scalpel and, after use of the scalpel or when not in use, must be brought into a lockable position in which the sharp parts of the scalpel blade are covered.
- the locking mechanisms are designed so that those positions can be reversibly and repeatedly set in which the scalpel blade can either be used or in which the scalpel blade is surrounded by the protective sheath in such a way that injury to the user or the handling person becomes impossible.
- the scalpel blade is a disposable blade that can be fixed in a reusable blade holder.
- the invention has for its object to improve the scalpel described at the outset in terms of its manageability and to make it less expensive in terms of its manufacturing costs.
- the slide has at its front end a downwardly projecting cross leg, the front of which forms an arcuate support and guide surface which defines the depth of cut of the blade in its position of use, and that Locking mechanism has an audible and palpable scaling that allows a change in the free projection of the blade corresponding to the depth of cut over the contact and guide surface in millimeter-precise steps.
- the scalpel should be designed as a single-use instrument.
- the cross leg and thus its support and guide surface form an angle of 90 ° with the underside of the slide, and if the support and guide surface is curved in relation to the longitudinal axis of the slide. It is thereby achieved that the blade of the scalpel is largely guided at an angle of at least approximately 90 ° to the skin of the patient during cutting, the arcuate configuration of the Cross leg allows free choice of preferred angles between the scalpel handle and the skin plane when cutting the skin.
- the claimed 90 ° angle results in smooth cut surfaces that can be adapted without tension when sewing. This optimizes wound healing and the cosmetic result.
- the audible and tactile scaling provided according to the invention make it easier for the doctor to precisely position the slide or to adjust the desired depth of cut to the millimeter.
- the blade In the protective position, the blade is covered on its upper side by the slide, while the transverse leg of the slide at least largely covers the underside of the cutting edge 5 of the blade 1.
- the scalpel according to the invention has the properties of a safety and precision instrument with regard to a precisely defined depth of cut and a precisely defined guide angle to the skin and can nevertheless be manufactured simply and inexpensively as a disposable instrument. This eliminates the need to change the blade.
- the slide serves to cover the blade and thus also as a transport lock and is part of a scaling device and thus takes over the function of an adjustment device with millimeter precision for a precise handling of the scalpel on the support and guide surface.
- an exemplary embodiment of the invention is shown. Show it
- FIG. 1 shows a scalpel with a slide in the use position
- FIG. 2 on an enlarged scale compared to FIG. 1, the front section of the scalpel according to FIG. 1 with the slide removed;
- FIG. 3 the slide according to FIG. 1 in isolation
- Figure 4 shows the slide according to Figure 3 in plan view
- FIG. 5 shows the underside of the
- the scalpel shown is equipped with a blade 1 which is positively fixed on a support surface 3 provided at the front end of a scalpel handle 2.
- a slide 4 is arranged opposite to it, which covers the blade 1 in its protective position (not shown in the drawing) and releases a cutting edge 5 of the blade 1 in its use position shown in FIG.
- the slider 4 has at its front end a downwardly projecting cross leg 6, the arcuate front of which forms a support and guide surface 7, in which a slot 8 is provided, through which the protrudes through the front end of the blade 1 when the slide 4 is moved into its position of use shown in Figure 1.
- the cross leg 6 or its support and guide surface 7 forms an angle ⁇ of 90 ° with the underside 9 of the slide 4 in a side view (see FIG. 3).
- the figures show that the support and guide surface 7 of the cross leg 6 is of arcuate design with respect to the longitudinal axis 10 of the slide 4 (see FIG. 4).
- the upper side 11 of the front section of the scalpel handle 2 is equipped with two undercut sliding grooves 12 arranged parallel to one another with a small spacing from one another (see FIG. 2), which can form a dovetail guide, and in which the slide 4 with sliding strips 13 correspondingly adapted in cross section is guided longitudinally displaceably, which are arranged on the underside 9 of the slide 4.
- a locking mechanism is provided between the top 11 of the scalpel handle 2 and the bottom 9 of the slide 4.
- the latter comprises a transverse corrugation 14 (see FIG. 2) arranged on the upper side 11 of the scalpel handle 2, into which a locking lug 15 engages in a spring-elastic manner, which projects downward from the lower side 9 of the slide 4 forming a sliding surface.
- This locking lug 15 is part of a spring tongue 17 formed by transverse incisions 16 in the slide 4 (see FIG. 5).
- the slider 4 which also leaves the actual grip area 2a of the scalpel handle 2 free in its position of use shown in FIG. 1, has a transverse corrugation 18 on its upper side over about two thirds of its length, starting at its rear end, so that the slider 4 from a finger of the hand of the scalpel handle 2 Physician can be pulled from its protective position into its position of use or pressed into its protective position from its position of use, in each case with audible and tactile overcoming of the scale 14, 15.
- the slide is preferably made of a transparent material.
- the transverse corrugation 14 enables the slide 4 to be displaced in millimeter-precise steps and thus a millimeter-precise adjustment of the cutting depth of the blade 1, the cutting depth resulting from the free projection 19 of the blade 1 over the contact and guide surface 7 (see FIG. 1).
