Problems solved by technology

However, the currently widely used manual micromanipulators only have two degrees of freedom of rotation and clamping, and often require the operator to perform a large number of auxiliary actions to achieve a certain working space, which increases the difficulty of surgical operations and reduces surgical efficiency. It will also bring unnecessary additional damage to the patient.

Embodiment Construction

[0015] Hereinafter, the present invention will be described in more detail with examples in conjunction with the accompanying drawings:

[0016] Combine Figure 1~3 , Combined figure 1 The manual multi-degree-of-freedom manipulator for surgery of the present invention is mainly composed of a fingertip clamping mechanism 1, a driving mechanism 2, and a rotating joint 3.

[0017] Combine figure 2 , Fingertip clamping mechanism consists of fingertips 1-7, fingertips 1-8, connecting shaft 1-9, connecting rod 1-5, connecting rod 1-6, connecting sleeve 1-2, long tube sleeve 1-1, Long putter 1-3, long putter 1-4. The fingertips 1-7 and 1-8 are connected to the connecting sleeve 1-2 through the connecting shaft 1-9, and the connecting sleeve 1-2 is fixedly connected with the long tube sleeve 1-1. The long push rod 1-3 and the long push rod 1-4 reciprocate in the long pipe sleeve 1-1. The two ends of the connecting rods 1-5 are respectively hinged with the fingertips 1-7 and the long pu...

Abstract

The invention aims to provide a manual multi-degree of freedom micro-manipulator for a surgical operation. The manual multi-degree of freedom micro-manipulator for the surgical operation comprises a fingertip clamping mechanism, a driving mechanism and a rotating joint, wherein the driving mechanism is connected with the fingertip clamping mechanism and controls the clamping and pitching of the fingertip clamping mechanism, and the rotating joint is connected with the fingertip clamping mechanism and controls the rotation of the fingertip clamping mechanism. The manual multi-degree of freedom micro-manipulator for the surgical operation has three degrees of freedom of clamping, pitching and rotating, and is good in stability and flexibility of a finger mechanism, simple in structure, easy to operate and capable of better meeting requirements of present minimally invasive surgeries.

Description

Technical field [0001] The invention relates to a medical device, specifically a manipulator for surgery. Background technique [0002] Compared with conventional open surgery, minimally invasive surgery has obvious advantages in terms of treatment effect, pain relief, recovery cycle, and medical cost. It is mainly operated with advanced surgical instruments to achieve excellent treatment results. At present, the application of minimally invasive surgery is becoming more and more extensive. In order to adapt to the accuracy and stability of the surgical operation, new minimally invasive surgical instruments are also developing rapidly. However, the currently widely used manual micromanipulators only contain two degrees of freedom, rotation and clamping, and often require a large number of auxiliary actions by the operator to reach a certain working space, thereby increasing the difficulty of the operation and reducing the efficiency of the operation. It will also cause unnecess...
