Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a device for adjusting the cutting precision during orthopedic robotic surgery. Background Technology

[0002] The intraoperative cutting precision adjustment device of the orthopedic robot is a core component of the orthopedic surgical robot system. It is used to adjust the robot's operating precision in real time during the operation to ensure the accuracy of bone cutting, drilling or implant positioning.

[0003] However, existing orthopedic surgical robots suffer from reduced surgical precision due to overheating of the saw blade or accumulation of small bone fragments during cutting; therefore, they do not meet current requirements. To address this, we propose a device for adjusting the cutting precision of orthopedic robots during surgery. Utility Model Content

[0004] The purpose of this invention is to provide a device for adjusting the cutting precision during orthopedic robotic surgery, in order to solve the problem mentioned in the background art where the cutting precision of existing orthopedic surgical robots is affected by overheating of the saw blade or the accumulation of small bone fragments generated during cutting.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cutting precision adjustment device for orthopedic robots during surgery, comprising a tool mounting flange, a fastening ring on the outer wall of the tool mounting flange, a first connecting rod and a second connecting rod mounted on both sides of the fastening ring, the outer walls of the first connecting rod and the second connecting rod being connected to a square splash guard by a snap fastener, a first bone pre-pressure point at the front end of the square splash guard, water suction pipe interfaces on both sides of the first bone pre-pressure point, and a second bone pre-pressure point at the rear end of the square splash guard.

[0006] Preferably, a saline tube is installed at the center of the tool mounting flange, and the saline tube passes through the front end of the tool mounting flange.

[0007] Preferably, a saw blade is movably mounted on the bottom end of the tool mounting flange via a keyway.

[0008] Preferably, the fastening ring is fixed to the outer wall of the tool mounting flange by fastening screws.

[0009] Preferably, the square splash guard can be replaced as needed.

[0010] Preferably, the water suction pipe interface is provided with a sealing ring inside.

[0011] Compared with the prior art, the beneficial effects of this utility model are: In use, this invention first fixes the tool mounting flange equipped with a through-type saline tube to the end of the robotic arm. The working range of the robotic arm is then positioned according to the pre-operative plan. Next, a suitable square splash guard is installed and connected to the suction line. The first and second bone pre-pressure points on the square splash guard are pressed against the bone to be operated on. After startup, the saline tube continuously fills the square splash guard with saline, and the suction line simultaneously extracts the mixed liquid containing bone fragments. This invention, through the closed square splash guard and dynamic liquid circulation system, can control the overall temperature of the saw blade while cleaning the bone fragments generated during cutting, reducing the impact of saw blade overheating or the accumulation of small bone fragments during cutting on surgical precision. Simultaneously, the square splash guard, through the first and second bone pre-pressure points, fixes the patient's bones to prevent unconscious convulsions that could affect surgical precision.
