Endoscope needle holder with head adjustable

Abstract

The endoscope needle holder with the head adjustable includes a nipper head, a nipper rod body and a nipper handle base. A hollow tubular structure is arranged in the nipper rod body, the nipper headis arranged at the front end of the nipper rod body, the nipper handle base is fixed at the back end of the nipper rod body, the rear end of the nipper handle base extends backwards and is provided with a nipper handle, the nipper handle includes a first nipper handle body and a second nipper handle body, the front end of the first nipper handle body is fixed at the rear end of the nipper handle base, the front end of the second nipper handle body is hinged to the rear portion of the nipper handle base, and the first nipper handle body and the second nipper handle body form the V-shaped nipperhandle. In summary, the clamping effect of the nipper head can be achieved by clamping the nipper handle, a nipper head steering drive mechanism drives a rotating shaft to rotate, thus the steering action of the nipper head is achieved, left and right torsion in different directions can be achieved by rotating a needle holder body, and finally 360-degree torsion can be achieved. The overall structure is reasonable in design, operation is convenient, and the needle holder is high in practicability.

Description

technical field [0001] The invention belongs to the field of medical technology, in particular to a head-adjustable endoscopic needle holder. Background technique [0002] The existing needle holder has a simple structure, and the opening and closing of the head can be realized by holding the handle tightly, which is used to clamp the sewing needle, and the handle has a steering rod to adjust the clamping plane of the needle holder; The head of the forceps is deflected, so it is difficult to suture the surgical incision that is not parallel to the long axis of the needle holder, and the operator needs to move the root of the needle holder around, because the needle holder penetrates into the body cavity by poking, The position of the poking card is relatively fixed. For the situation where the operating plane of the needle holder needs to be changed at a large angle, the operator needs to twist the clamp handle to a large extent outside the body and maintain it for a certain...

Problems solved by technology

[0002] The existing needle holder has a simple structure, and the opening and closing of the head can be realized by holding the handle tightly, which is used to clamp the sewing needle, and the handle has a steering rod to adjust the clamping plane of the needle holder; The head of the forceps is deflected, so it is more difficult to suture the surgical incision that is not parallel to the long axis of the needle holder. The operator needs to move the root of the needle holder around. Since the needle holder penetrates into the body cavity by poking, The position of the poking card is relatively fixed. For the situation where the operating plane of the needle holder needs to be changed at a large angle, the operator needs to twist the pliers handle to a large extent outside the body and maintain it for a certain period of time, which may easily lead to operator fatigue.
