Embodiment 1

[0042] This embodiment discloses an integrated surgical system for reduction and fixation of extremity fractures, such as figure 1 As shown, it includes: a robot system 1 , an electric operating table 2 , an external bone fixation device 3 and a broken bone clamping device 4 .

[0043] The robot system 1 includes a robot arm 101, a teach pendant 102 and a robot arm control cabinet 103, such as Figure 2-4shown. The robotic arm 101 is connected to the electric operating table 2 through a movable base; the robotic arm control cabinet 103 is respectively connected to the robotic arm 101 and the teach pendant 102, and is used to send control signals to the robotic arm. It has an expansion port and can be connected to an external The control signal and the coordinates and attitude information of the end of the manipulator are displayed through the teach pendant. The teach pendant has the ability to program online and load external control programs, and sends control commands to th...

Embodiment 2

[0074] The purpose of this embodiment is to provide a control method, which is applied to the teaching pendant in the first embodiment. During the reset and fix operation of the system, it is configured to perform the following steps:

[0075] (1) After fixing the proximal and distal ends of the broken bone with the external fixation device, obtain CT images including the electric operating table, the patient and the external fixation device for three-dimensional modeling;

[0076] (2) After installing the broken bone holding device on the end of the mechanical arm, obtain the coordinates of the needle point of the calibration needle on the broken bone holding device in real time; send control instructions to the mechanical arm to drive the calibration needles of the broken bone holding device to insert respectively Metal balls on the bone external fixation device to obtain the coordinates of the center of each metal ball;

[0077] (3) Install a universal clamp on the broken ...

Abstract

The invention discloses a reduction and fixation integrated operation system for limb fractures and a control method. The system comprises an electric operating table, a mechanical arm and a demonstrator, wherein the mechanical arm is connected to the electric operating table through a movable base, the tail end of the mechanical arm is used for being connected with a broken bone clamping device,and a posture sensor is arranged; a connecting device is arranged on the electric operating table and used for being connected with a bone external fixing device; and the demonstrator is connected with the posture sensor and the mechanical arm and used for obtaining the posture of the tail end of the mechanical arm in real time and sending a control instruction to the mechanical arm. The bone external fixing device and the broken bone clamping device are connected to the operating table, and through cooperation of the bone external fixing device and the broken bone clamping device, the two processes of reduction and fixation can be achieved on the basis of one device.

Description

technical field [0001] The invention belongs to the technical field of medical auxiliary systems, and in particular relates to a reduction and fixation integrated operation system and control method for extremity fractures. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Fractures of extremities are common diseases in orthopedics, with the characteristics of common incidence and high disability rate. For extremity fractures, most hospitals currently use open reduction and internal fixation of fractures and manipulative restoration plaster / splint external fixation, but both have obvious disadvantages. Among them, open reduction and internal fixation is more traumatic, destroys blood supply, increases the chance of infection, easily causes joint adhesion, and seriously affects fracture healing and recovery; the accuracy of manual reduction...
