Bendable hoe-blade-shaped surgical instrument

Abstract

The invention belongs to the field of medical apparatus and instruments and particularly relates to bendable hoe-blade-shaped surgical instrument specially used for removing an intrauterine adhesion scar under a minimally invasive surgery hysteroscope. The bendable hoe-blade-shaped surgical instrument comprises a steel tube with the outer diameter being 3mm and is characterized in that a plane where the included angle of a blade handle and a blade coincides with a plane where a bent bendable joint tube is located, and the angle sum of the bending angle of the bendable joint tube and the included angle of the blade handle and the blade is 180 degrees. The bendable hoe-blade-shaped surgical instrument has the advantages that the intrauterine adhesion scar can be thoroughly removed under theminimally invasive surgery hysteroscope, and single-hand operation and multi-angle operation by operation staff are facilitated by the coordination of an operation handle and an auxiliary handle and the lock catch of the auxiliary handle; the defects that the removing of the intrauterine adhesion scar in intrauterine adhesion surgery is troublesome and not thorough and the damages the endometriumare overcome, the scar can be removed conveniently, surgery time can be shortened, and the endometrium can be protected; the bendable hoe-blade-shaped surgical instrument is simple in overall structure, convenient to use and maintain and low in manufacturing cost.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a bendable hoe-shaped surgical device specially used in the removal of intrauterine adhesion scars under hysteroscopy in minimally invasive operations. Background technique [0002] At present, it should meet the requirements of the development of minimally invasive surgery. When carrying out various hysteroscopic and single-port laparoscopic operations at home and abroad, although the surgical instruments used can be 3mm in diameter, they are all rigid straight tube instruments, while the 5mm bendable and rotatable surgical instruments used cannot It is used in hysteroscopy; currently, only scissors, pliers, and grasping forceps are used as cold knife instruments with a diameter of 3mm. Cutting in any other direction cannot completely remove the scar, and the operation time is long, requiring the operator to constantly adjust the direction of the hysteroscope body (especially for...

Problems solved by technology

When carrying out various hysteroscopic and single-port laparoscopic operations at home and abroad, although the surgical instruments used can be 3mm in diameter, they are all rigid straight tube instruments, while the 5mm bendable and rotatable surgical instruments used cannot It is used in hysteroscopy; currently, only scissors, pliers, and grasping forceps are used as cold knife instruments with a diameter of 3mm. Cutting in any other direction cannot completely remove the scar, and the operation time is long, requiring the operator to constantly adjust the direction of the hysteroscope body (especially for the narrow operating space of the perineal area, which is not conducive to the choice of angle), and it is easy to injure Endometrium and other disadvantages, so it is necessary to invent a convenient surgical instrument for removing intrauterine adhesion scars
