Robot arm for self-adaptive pressure reduction tunnel type robot

Abstract

The invention relates to a robot arm for a self-adaptive pressure reduction tunnel type robot, which comprises a machine head connecting base, a buffering assembly is arranged on the machine head connecting base, a telescopic column is arranged in the buffering assembly, a working channel is arranged below the telescopic column, a rotating motor is installed at the upper end of the telescopic column, a hollow shaft is arranged at the upper end of the rotating motor, the hollow shaft is provided with a fixing seat, the fixing seat is provided with a hollow shaft lifting motor, a communicated cavity is formed among the hollow shaft lifting motor, the fixing seat, the hollow shaft, the rotating motor, the telescopic column and the working channel, and a surgical device is arranged in the cavity. Therefore, an upper telescopic spring and a lower telescopic spring can meet the requirement for effective floating of the telescopic column in a specific interval, the telescopic column can adapt to the change of the bone height and the change caused by respiratory movement, and the implementation progress is accelerated. By means of the rotating motor, the surgical device can be effectively driven to rotate by 360 degrees, and a better soft tissue ablation resection pose is achieved.

Description

technical field [0001] The invention relates to a robot arm for minimally invasive surgery, in particular to a robot arm for an adaptive decompression tunnel type robot. Background technique [0002] In recent years, some significant progress has been made in the field of spinal surgery, and the surgical treatment of herniated disc will undergo revolutionary changes: the mode of "removing" the herniated intervertebral disc as the main treatment method will enter the mode of "preserving" the herniated intervertebral disc to allow it to absorb naturally main mode. It has been reported in the literature that artificially performing double open spinal expansion (CMEL) can extensively "induce" natural resorption (RHNP) of the herniated intervertebral disc, the resorption ratio can reach 81.3%, and the resorption rate can reach 100%. However, there are problems of large incision and cumbersome surgical operation, especially the installation of steel plates, in manual double open ...

Problems solved by technology

However, there are problems of large incisions and cumbersome surgical operations, especially the installation of steel plates, in manual double-open spinal expansion surgery (CMEL), which affects the promotion of this new technology.

Although spinal surgery robots have been successfully applied clinically, including Mazor spine assistant in Israel, SPINEBOT spine robot in South Korea, Mazor X spine surgery robot in the United States, and Tianji spine surgery robot in my country, etc., they basically all use The registration method of intraoperative X-ray images and preoperative CT images can only be used for pedicle screw placement, and its function is very single

At present, there is no minimally invasive spinal surgery robot that can complete the CMEL operation, realize double-open decompression of the spinal canal, move back and expand the spinous process ligament complex, and "induce" extensive natural resorption (RHNP) of herniated intervertebral discs.
