This invention discloses a surgical guide and its manufacturing method. The surgical guide includes: a plate body with at least two guide grooves penetrating the plate body and interconnected at an angle, the angle being the osteotomy angle; and a positioning part located at the edge of the plate body, used to locate the relative position between two bone fragments after osteotomy. Using this design, the guide grooves penetrating the plate body guide the osteotomy path of osteotomy tools during surgery, such as oscillating saw blades or milling cutters. Furthermore, the interconnected guide grooves provide the osteotomy angle, improving the accuracy of osteotomy. The positioning part can locate the relative position of the two bone fragments after osteotomy, thereby improving the accuracy of bone fragment positioning, thus improving the therapeutic effect of surgical correction of deformities and reducing postoperative pain. Additionally, the positioning part is located at the edge of the plate body, allowing for positioning using the edge of the plate body.

Provided are a medical ultrasonic scalpel, a medical ultrasonic scalpel system, and a robot-assisted ultrasonic scalpel system, belonging to the technical field of medical instruments. The medical ultrasonic scalpel comprises a scalpel head (10). The scalpel head (10) is provided with a first end face (101) and a cutting groove (102). The cutting groove (102) passes through the first end face (101), and the cutting groove (102) allows the first end face (101) to form at least one annular cutting face (103). During the cutting or fragmentation of a bone tissue, the bone tissue corresponding to the position where the cutting groove (102) is located does not make contact with the cutting face (103), that is, it is not needed to cut or fragment the bone tissue corresponding to the position, but the bone tissue corresponding to the periphery of the cutting groove (102) makes contact with the cutting face (103) so as to be cut or fragmented. In this way, the cutting face (103) creates a relatively small area of cutting or fragmentation on the bone tissue, but can still cut or fragment large bone pieces. Additionally, since the cutting face (103) creates a smaller area of cutting or fragmentation on the bone tissue, cutting or fragmenting bone pieces of the same size takes less time, achieving higher working efficiency.
