Abstract

The utility model discloses a little needle sword stripper, including little needle sword body, the one end of little needle sword body is equipped with the cutting edge, the cutting edge is "D" style of calligraphy or circular. The utility model has the advantages of do benefit to and diversely open the wound and can reduce the wound that receives.

Description

Small needle knife stripper

Technical Field

The utility model relates to the field of medical auxiliary equipment, in particular to a small needle knife stripper.

Background

At present, in most minimally invasive surgeries, small needle knives with the width smaller than 1mm are used for peeling skin and tissues, wounds caused by surgeries carried out by the small needle knives are small, bleeding is little, and the recovery period is short, but the small needle knives have an obvious defect that the wounds can be only created along one direction and cannot be transformed in multiple directions, so that when the wounds in other directions exist in the process of creating, the wounds cannot be reasonably created, the small needle knives must be taken out to find the wounds again, and the injuries to patients are large.

SUMMERY OF THE UTILITY MODEL

To the above problem, the utility model provides a little needle sword stripper has the advantage that does benefit to and diversely opens the wound and can reduce the wound that receives.

The technical scheme of the utility model is that:

a small needle knife stripper comprises a small needle knife body, wherein a cutting edge is arranged at one end of the small needle knife body, and the cutting edge is D-shaped or circular.

The working principle of the technical scheme is as follows:

when minimally invasive surgery is carried out, the tail part needing to be stripped in a wound is determined, then the small needle knife body with the D-shaped cutting edge or the circular cutting edge is selected to be used, after the wound is determined to be opened, the small needle knife body is cut into the opened wound, then skin and tissues are separated, the small needle knife body with the D-shaped cutting edge can be stripped along one direction, and can also be stripped along the cutting edge direction of the D-shaped cutting edge, and the small needle knife body with the circular cutting edge can be stripped in the wound in multiple directions.

In a further technical scheme, the blade is provided with edge lines.

The edge lines are arranged, so that the small needle knife body can cut into the small needle knife body more easily and is sharper.

In a further technical scheme, the maximum thickness of the cutting edge is smaller than that of the small needle knife body, and the connecting surface of the cutting edge and the small needle knife body is an inclined surface.

The inclined plane that establishes on the little needle sword body mainly makes skin and the tissue that separate take place the adhesion, influences subsequent operation.

In a further technical scheme, the width of the small needle knife body is less than 0.8 mm.

The requirement of 0.8mm is to make the opening smaller, and reduce the wound caused by opening.

The utility model has the advantages that:

1. the multi-directional wound can be opened, so that the wound is smaller, the bleeding amount is smaller, and the recovery period is shortened;

2. the arrangement of the edge lines enables the small needle knife body to be cut into more easily and sharper;

3. the inclined plane arranged on the small needle knife body mainly enables the separated skin and tissue to be adhered, and subsequent operation is influenced;

4. the requirement of 0.8mm is to make the opening smaller, and reduce the wound caused by opening.

Detailed Description

The embodiments of the present invention will be further explained with reference to the drawings.

Example (b):

as shown in fig. 1-3, a small needle knife stripper comprises a small needle knife body 1, wherein a blade 2 is arranged at one end of the small needle knife body 1, and the blade 2 is in a shape of "D" or a circle.

The working principle of the technical scheme is as follows:

when minimally invasive surgery is carried out, the tail part needing to be stripped in a wound is determined, then a small needle knife body with a D-shaped cutting edge 4 or a circular cutting edge 5 is selected to be used, after the wound is determined to be opened, the small needle knife body 1 is cut into the opened wound, then skin and tissue are separated, the small needle knife body 1 with the D-shaped cutting edge 4 can be stripped along one direction, the small needle knife body with the circular cutting edge 5 can also be stripped along the cutting edge direction of the D-shaped cutting edge 4, and the small needle knife body with the circular cutting edge 5 can be stripped in the opening in multiple directions.

In another embodiment, as shown in fig. 2-3, the blade 2 is provided with a cutting line 3.

The edge lines 3 are arranged so that the small needle knife body 1 can cut into the small needle knife body more easily and is sharper.

In another embodiment, as shown in fig. 1, the maximum thickness of the cutting edge 2 is smaller than that of the small needle knife body 1, and the connecting surface between the cutting edge 2 and the small needle knife body 1 is a bevel.

The inclined plane arranged on the small needle knife body 1 mainly enables the separated skin and tissue to be adhered, and subsequent operation is affected.

In another embodiment, the small needle-knife body 1 has a width of less than 0.8 mm.

The setting requirement of 0.8mm is to make the opening wound smaller, and reduce the wound caused by opening wound.

The above-mentioned embodiments only express the specific embodiments of the present invention, and the description thereof is specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.

Claims
