Abstract

The invention relates to a laser osteotomy assisted total hip replacement surgical robot, and relates to the technical field of medical instruments, the laser osteotomy assisted total hip replacement surgical robot comprises a control computer body, a base is mounted at the front end of the top of the control computer body, the top of the base is connected with the robot body, and a connecting line is arranged on the left side of the control computer body; a support is arranged in front of the control computer body, an operating table is fixed to the top of the support, the other end of a connecting line is connected with an auxiliary device, a laser cutting end executor is installed at the front end of the robot body, and the laser cutting end executor is used for cutting at a preset position according to a preset cutting amount. The right side of the laser cutting end effector is connected with an auxiliary water spraying and air blowing device, and the auxiliary water spraying and air blowing device is used for spraying water and blowing air to the acetabulum. By adopting a laser osteotomy mode, potential safety hazards caused by manual grinding are effectively avoided, and the safety degree of an operation is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a laser osteotomy-assisted total hip replacement surgical robot. Background technique [0002] At present, acetabular molding in total hip arthroplasty relies on acetabular reaming to polish the acetabular bone, and the grinding depth and orientation mainly depend on the operator's visual and experience judgment. Such molding methods will cause large errors. [0003] When the acetabular reamer is polished, it relies on mechanical force to destroy the trabecular bone to achieve bone grinding, which will cause damage to the trabecular bone structure and cause more bleeding, up to 1000ml. The damaged trabecular bone will increase the healing time during the tissue repair process. , is a potential risk factor for poor ingrowth of acetabular cup prosthesis. [0004] The hand-polished acetabular fossa is not a regular hemispherical shape, and cannot be completely matched with ...
