Episiotomy shear

Abstract

The invention belongs to the field of a medical tool, and particularly relates to an episiotomy shear. The episiotomy shear comprises two shearing arms, wherein the two shearing arms are mutually hinged; each shearing arm comprises a shearing part and a handle part; the shearing part is positioned at the front part of a hinging point and is provided with a shearing edge; the handle part is positioned at the back part of the hinging point; the shearing part comprises a connecting section and a shearing section; the connecting section is formed by extending in the length direction of the handlepart; the shearing section is formed by bending and upwards raising the front end of the connecting end; the shearing edge is arranged on the shearing section;the shearing parts on the two shearing arms respectively are devided into a lower shearing part 2-1 extending into the perineum and an upper shearing part 2-2 positioned outside the perineum; a marker rod is erected on the outer side surface, backing to the lower shearing part, of the upper shearing part; an included angle between the marker rod and the upper shearing part is 60 degrees. Through the arrangement of the marker rod, the marker rod and the upper shearing part are positioned outside the perineum in the use process; the perineum length can be simply, fast and conveniently evaluated; through the positioning of the marker rod vertical to the anus, the episiotomy shear placing position, i.e., the 60-degree angle of the episiotomy can be accurately and fast positioned; the episiotomy angle is fixed.

Description

technical field [0001] The invention belongs to the field of medical tools, and in particular relates to scissors for lateral perineal incision. Background technique [0002] In traditional episiotomy, it is generally required to evaluate the placement position and angle of the specific episiotomy according to the perineal conditions during the episiotomy operation, so the position and angle of the episiotomy have obvious subjectivity and uncertainty. It is easy to cause perineal laceration due to improper placement and angle of side cutting shears. In clinical practice, visual inspection is generally used to evaluate the length of the perineal body, resulting in very subjective results and large errors, resulting in inaccurate placement of perineal scissors, leading to an increase in clinical operation error rates. The general standard requires the angle of lateral incision to be 60°, but in actual work, due to the large subjective error, the angle of lateral incision is o...

[0002] In traditional episiotomy, it is generally required to evaluate the placement position and angle of the specific episiotomy according to the perineal conditions during the episiotomy operation, so the position and angle of the episiotomy have obvious subjectivity and uncertainty. It is easy to cause perineal laceration due to improper placement and angle of side cutting shears

In clinical practice, visual inspection is generally used to evaluate the length of the perineal body, which leads to very subjective results and large errors, resulting in inaccurate placement of perineal scissors, resulting in an increase in clinical operation error rate

The general standard requires that the angle of lateral incision is 60°, but in actual work, due to the large subjective error, the angle of lateral incision is often too large or too small, which fails to reduce the tension of the perineum during childbirth and protect the perineum.
