All-dimensional automatic traction and support device of dragline type endoscopic surgical instrument

Abstract

The invention discloses an all-dimensional automatic traction and support device of a dragline type endoscopic surgical instrument, which comprises a fixed part, an instrument clamping part and a dragline type universal free arm which is connected between the fixed part and the instrument clamping part, wherein the dragline type universal free arm is formed by connecting a plurality of joint parts in series through a dragline; and an electric traction device is arranged on the fixed part, one end of the dragline is connected onto the instrument clamping part, and the other end of the dragline is connected onto the electric traction device of the fixed part. The dragline type universal free arm is used to fix the position and angle of an abdomen microscope, the electric and manual traction devices are arranged on the fixed part to control the movement state of the dragline type universal free arm, the device can be directly used for endoscopic surgery, also can be used to fix the instrument for open surgery, endoscopic surgery and other types of surgeries too, not only has a simple structure, but also is convenient to use.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and relates to a pulling and supporting device, in particular to an automatic pulling and supporting device for endoscopic surgical instruments. Background technique [0002] Laparoscopic surgery is widely used for its advantages of less trauma and faster recovery, and it is an important progress and development direction of surgical treatment. Laparoscopic surgery has high requirements on the stability of the assistant's operation. For example, the assistant needs to support the lens and complete auxiliary operations such as pulling and pushing with laparoscopic instruments, and then keep it stable for a long time. A slight shaking of the assistant's breathing or limbs can often cause the loss of the surgical field of view or operating space and force the interruption of the operation, which affects the smooth progress of the operation to varying degrees, and even threatens the safet...

AI Technical Summary

Problems solved by technology

A slight shaking of the assistant's breathing or limbs can often cause the loss of the surgical field of view or operating space and force the interruption of the operation, which affects the smooth progress of the operation to varying degrees, and even threatens the safety of the patient during critical operations

On the other hand, since laparoscopic surgery often takes a long time, the assistant remains fixed for a long time, which is also a great challenge to his physical strength

[0003] Due to the different surgical methods, auxiliary devices such as automatic retractors and automatic retractors used in traditional open surgery cannot be used in laparoscopic surgery at all, and its working principle is also difficult to replicate in laparoscopic surgery
