Embodiment 1

[0040] This embodiment provides a positioning aid, including a base, a robot arm, a positioning device and a control unit.

[0041] The base is movably connected with a mechanical arm, and the mechanical arm is used for the operator to operate on the patient on the operating table;

[0042] A positioning device is fixedly installed on the base, and the positioning device is used to transmit a positioning signal to the operating table;

[0043] The control unit is coupled with the robotic arm and the positioning device respectively, and is used to control the movement of the robotic arm and control the positioning device to output positioning information to the operating table, so that the operator can determine the spatial relationship between the robotic arm and the operating table based on the positioning information, and A target work area is determined based on the positioning information.

[0044] The base can include a column (not shown in the figure, only the direction...

Embodiment 2

[0051] Such as figure 2 As shown, the positioning aid provided by this embodiment is basically the same as that of Embodiment 1, except that the distance between the first positioning device 3 and the column is smaller than the distance between the second positioning device 4 and the column.

[0052] Specifically, the first positioning device 3 is located at the inner side of the end of the beam 1, and the second positioning device 4 is located at a position closer to the end of the beam 1. At this time, the target working area is located in the circumscribed circle of the cross projection of the second positioning information ( figure 2 The dotted circle shown), that is, within the circumscribed circle area formed by the cross-shaped light spot, the position for aligning the incision of the patient can be determined.

Embodiment 3

[0054] This embodiment provides a positioning assistance method, which includes:

[0055] S1. Determine the position of the operating table 2, and move the base based on the position of the operating table 2 to approach the operating table 2;

[0056] S2. After the base moves, the control unit controls one or more mechanical arms to move to the first position. The first position is the position where the positioning information of the positioning device can be irradiated to the operating table 2. By moving the mechanical arm Arm, so as to prevent the existence of the mechanical arm from blocking the output positioning information of the positioning device from being projected onto the operating table 2 or the patient's body, affecting the positioning effect.

[0057] S3. After the mechanical arm moves, the control unit controls the positioning device to send a positioning signal, and the operator adjusts the spatial relationship between the base and the operating table accordi...

Abstract

The invention relates to a positioning auxiliary device and a positioning auxiliary method, the device comprises a base, the base is movably connected with a mechanical arm, and the mechanical arm is used for surgical operation; a positioning device which is arranged on the base and is used for transmitting a positioning signal to an operation workbench; a control unit, which communicates with the mechanical arm and is used for controlling the mechanical arm to move, and the control unit further communicates with the positioning device and is used for controlling the positioning device to transmit positioning information to the operation workbench and determining the space relation between the base and the operation workbench and the target working area based on the positioning information. The positioning auxiliary device provided by the invention is used for controlling the positioning device to output the positioning information relative to the operation workbench, an operator determines the space relation between the base and the operation workbench through the position relation of the positioning information, determines the target working area based on the positioning information, the problem that existing medical instruments and the operation workbench are difficult to align and position is solved, and the target position of the surgical incision is determined through auxiliary positioning.

Description

technical field [0001] The invention relates to a positioning assistance device and a positioning assistance method, and relates to the technical field of medical devices. Background technique [0002] In minimally invasive medical procedures, preoperative layout is usually required before the operation is performed, that is, the medical device is moved to the vicinity of the desired working position, and then the medical device and the operating table are in the best position through the adjustment of the position and direction, so as to determine The target position of the surgical incision is convenient for the mechanical operation arm of the medical device to smoothly enter the human body through the sheath channel at the surgical incision for surgical operation. [0003] For the existing minimally invasive medical devices, because there is no relevant positioning device, it usually takes a lot of time and energy to adjust the position of the medical device during the pr...
