Description

Disposable sterile scalpel

Technical Field

The utility model relates to the field of medical instruments, in particular to a disposable sterile scalpel.

Background

Disposable scalpels are typically composed of a blade and a handle, the blade being disposable. The blade is typically formed with a cutting edge and a mounting groove for interfacing with the scalpel handle, and is typically formed of pure titanium, titanium alloy, stainless steel or carbon steel material, and is typically disposable. The knife edge is used for cutting skin and muscle during dissection, the knife tip is used for repairing blood vessels and nerves, and the knife handle is used for blunt separation. The blade and the knife handle with proper types are selected according to the size of the wound.

However, when a scalpel blade is mounted, the blade is usually held by a needle and mounted on a scalpel handle, and the blade itself has a smooth surface and no specific holding position, and the holding position cannot be limited, which results in easy holding to the blade edge position of the blade when holding the blade, thereby causing deformation of the blade edge position, affecting the accuracy in surgical cutting, and if the blade edge is held to cause uneven surface, the patient is aggravated by surgical wound at the cutting position, which is unfavorable for wound recovery. Accordingly, one skilled in the art would provide a single use sterile scalpel to address the problems set forth in the background above.

Disclosure of Invention

In order to solve the technical problems, the utility model provides a disposable sterile scalpel, which comprises a scalpel body, wherein the scalpel body is provided with a blade;

the utility model discloses a cutter blade, including blade, clamping groove, first hypotenuse and second hypotenuse, the blade is located the blade below, blade fixedly connected with grip block, and the grip block is located the blade top, the grip block both sides are equipped with the clamping groove, the clamping groove is equipped with first hypotenuse, the clamping groove is equipped with the second hypotenuse.

Preferably: the middle part of the cutter body is provided with a clamping groove, and the cutter body is provided with a fitting edge.

Preferably: the angle between the first bevel edge and the top of the blade body is 45-60 degrees.

Preferably, the angle between the second bevel edge and the top of the blade body is 40-30 degrees.

Preferably, an arc edge is arranged between the first inclined edge and the second inclined edge.

Preferably, the clamping groove comprises a residual groove.

The utility model has the technical effects and advantages that:

1. the clamping plate is clamped by the needle holder, the needle holder only clamps the clamping groove part, so that the needle holder is prevented from clamping the blade part, the surface of the blade is prevented from being clamped and deformed, the blade is ensured to be smooth, the accuracy of surgical cutting is improved, the surgical wound caused by cutting can be reduced by the smooth blade, and the blade is prevented from being polluted by the needle holder when the blade body is clamped;

2. the edge is held to the needle and is laminated with first hypotenuse, utilizes first hypotenuse to hold the effect of resisting to the needle, prevents to hold the slip with the too big or needle of holding the centre gripping and too loose and lead to the needle to hold because of installing the blade when pushing away, guarantees that the blade inserts in the handle of a knife steadily.

Detailed Description

The utility model will be described in further detail with reference to the drawings and the detailed description. The embodiments of the utility model have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the utility model in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments were chosen and described in order to best explain the principles of the utility model and the practical application, and to enable others of ordinary skill in the art to understand the utility model for various embodiments with various modifications as are suited to the particular use contemplated.

Referring to fig. 1 to 4, in this embodiment, a disposable sterile scalpel is provided, which includes a blade 1, the blade 1 is provided with a blade 2, a clamping groove 3 is provided in the middle of the blade 1, and the blade 1 is provided with a fitting edge 4;

the cutter blade 2 is positioned below the cutter body 1, the cutter body 1 is fixedly connected with a clamping plate 54, the clamping plate 54 is positioned above the cutter body 1, clamping grooves 5 are formed in two sides of the clamping plate 54, a first bevel edge 52 is arranged in the clamping grooves 5, and an angle between the first bevel edge 52 and the top of the cutter body 1 is 45-60 degrees;

the clamping groove 5 is provided with a second inclined edge 51, an angle between the second inclined edge 51 and the top of the blade body 1 is 40 degrees to 30 degrees, an arc edge 53 is arranged between the first inclined edge 52 and the second inclined edge 51, and the clamping groove 5 comprises a residual groove 55.

The working principle of the utility model is as follows:

the clamping plate 54 is arranged at a position above the cutter body 1 far away from the cutter edge 2, the thickness of the cutter body 1 is larger than that of the clamping plate 54, so that the clamping plate 54 forms a clamping groove 5, a doctor holds a needle by one hand and holds a cutter handle by the other hand when installing a cutter blade, the needle is used for clamping the clamping plate 54, the needle is only used for clamping the part of the clamping groove 5, the needle is prevented from clamping the part of the cutter edge 2, the surface of the cutter edge 2 is prevented from being clamped and deformed, the flatness of the cutter edge 2 is ensured, the precision of surgical cutting is improved, the surgical wound caused by cutting can be reduced by the flat cutter edge, and the cutter edge 2 is prevented from being polluted when the cutter body 1 is clamped by the needle;

the needle holding edge is attached to the first inclined edge 52, the first inclined edge 52 is used for resisting the needle holding, so that the needle holding slipping caused by overlarge force or overlarge needle holding clamping during pushing due to the installation of the blade is prevented, and the stable insertion of the cutter body 1 into the cutter handle is ensured;

the second inclined edge 51 is inclined at a different angle from the first inclined edge 52, so that the holding area of the needle holder is smaller than the area of the holding groove 5, and the unclamped portion forms the residual groove 55.

It will be apparent that the described embodiments are only some, but not all, embodiments of the utility model. All other embodiments, which can be made by those skilled in the art and which are included in the embodiments of the present utility model without the inventive step, are intended to be within the scope of the present utility model.
