Adjustable needle holder for endoscopic surgery

Abstract

The invention discloses an adjustable needle holder for endoscopic surgery. The adjustable needle holder comprises a forceps rod, a forceps jaw, a forceps handle, a clipping assembly, a bending assembly and a clamping assembly. The forceps jaw is rotationally mounted at the left end of the forceps rod via a hinge pin, the forceps handle is fixedly mounted at the right end of the forceps rod, the clipping assembly is mounted between the forceps jaw and the forceps handle, the forceps jaw can be opened and closed by the aid of the clipping assembly, the bending assembly is mounted between the forceps jaw and the forceps handle, the forceps jaw can be bent by the aid of the bending assembly, the clamping assembly is mounted between the clipping assembly and the forceps handle, and the forceps handle can stably clamp suture needles by the aid of the clamping assembly. The adjustable needle holder has the advantages that the adjustable needle holder is simple in structure and convenient to operate, and the forceps jaw of the needle holder can be controllably bent and adjusted.

Description

technical field [0001] The present invention relates to a needle holder suitable for minimally invasive surgery, in particular to an adjustable laparoscopic surgery with simple structure, convenient operation and controllable bending adjustment of the jaw of the needle holder. needle holder. Background technique [0002] With the continuous advancement of medical technology, people have higher and higher requirements for the effect and quality of medical services. Minimally invasive laparoscopic surgery will be the future development direction of the surgical field. Laparoscopic surgery has high technical requirements, complex operation, and a variety of surgical instruments used in the operation. Among them, the endoscopic needle holder is a routinely used needle holding device in the minimally invasive surgery process.

Problems solved by technology

Laparoscopic surgery has high technical requirements, complex operation, and a variety of surgical instruments used in the operation. Among them, the endoscopic needle holder is a routinely used needle holding device in the minimally invasive surgery process. Due to the complex internal structure of the human body, minimally invasive surgical incision Small size, limited field of view, and cramped operating space, therefore, it is often necessary to establish multiple operating channels, and a variety of instruments are required to cooperate with the operation during the operation, and surgical instruments are frequently replaced

However, the existing needle holders and other surgical instruments are mostly non-bendable. Stiffly entering and leaving the operative field during the operation will inevitably block the line of sight and affect the operation; in addition, in some special parts, due to anatomical reasons or limited space , the traditional non-steering and bent needle holder is difficult to complete the operation, which adds difficulty to the operation, resulting in prolonged operation time, increased bleeding, increased use of anesthesia and other drugs, and easily leads to postoperative complications.
