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.

This invention provides an arthroscopic tool for locating and reducing tibial plateau fractures, belonging to the field of medical device technology. The tool includes a positioning component for determining the X-position of the collapsed bone fragment and a guide calibration component for guiding the guide pin. The positioning component includes a first positioning arm, a second positioning arm, and a protrusion. The guide calibration component and the second positioning arm are located on the same side of the first positioning arm, and the second positioning arm is rotatably connected to the first positioning arm via a rotating component. The first and second positioning arms are connected by a rotating component, allowing the second positioning arm to be angled according to the patient's anatomical structure to accommodate individual differences. Furthermore, by setting the guide calibration component, the guide sleeve is always oriented towards the protrusion, maintaining the accuracy of the guiding path even when the first and second positioning arms rotate relative to each other.

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.
