The present invention provides a therapeutic instrument including a vertebral drilling guide and a bone drilling instrument, the therapeutic instrument being configured as follows. The vertebral drilling guide is a hollow cylindrical shape along a central axis, with a first scoop part opening in a direction perpendicular to the central axis at the leading-end side along the central axis and a second scoop part opening in the opposite direction of the perpendicular direction at the base-end side along the central axis. The bone drilling instrument is rod-shaped, is smoothly curved in the perpendicular direction along a central axis, and when inserted into the vertebral drilling guide along the central axis from the distal end of the second scoop part of the vertebral drilling guide, a leading-end portion thereof protrudes out of an opening in the first scoop part. This makes it possible to provide a safe therapeutic instrument that enables precise drilling of an intended area all the way inside the vertebral body while minimizing skin incision in percutaneous vertebroplasty of fractures and prophylactic reinforcement of the vertebral body with bone cement.

The percutaneous vertebroplasty combined instrument comprises an expandable supporting mesh bag, the expandable supporting mesh bag is provided with an outer-layer mesh bag body and an inner-layer mesh bag body, and the two ends of the outer-layer mesh bag body and the two ends of the inner-layer mesh bag body are closed to form an annular filling cavity and a center guiding cavity; the far end of the hollow distraction rod is detachably connected with the connector at the near end of the expandable supporting mesh bag, and an inner cavity of the hollow distraction rod is communicated with the central guide cavity; the directional injection core tube is slidably and rotatably arranged in the hollow opening rod in a penetrating manner, and the far end of the directional injection core tube extends into the central guide cavity and is provided with a radial directional discharge port; the rotary driving handle is arranged at the near end of the hollow distraction rod, is in transmission connection with the directional injection core tube and is used for driving the directional injection core tube to rotate so as to change the orientation of the discharge port. The double-layer structure of the expandable supporting mesh bag is used for achieving leakage prevention of the bone cement physical barrier, targeted filling is achieved through the rotatable directional injection core tube, the problems that in the prior art, the bone cement leakage risk is high, and the injection direction is uncontrollable are solved, and the safety and accuracy of an operation are improved.

The disclosure relates to a computer-implemented method for determination of a bone cement volume of a bone cement for a percutaneous vertebroplasty, which reduces complications due to the information provided by the method. The computer-implemented method includes: reading in or receiving data about a bone structure of a bone section; determining a bone density distribution of the bone section depending on the data; determining a bone space in the bone section depending on the determined bone density distribution, wherein a bone density of the bone space is less than a predetermined density threshold value; determining a bone space volume of the determined bone space; and determining and outputting the bone cement volume depending on the determined bone space volume.

The present invention is a therapeutic instrument including a vertebral body perforation guide and a vertebral body processing tool, and is configured as follows. The vertebral body perforation guide is a hollow cylinder running along a central axis, and comprises a distal end spatula portion, an intermediate portion, and a terminus portion, in the stated order from the proximal side along the central axis. The distal end spatula portion opens in a direction perpendicular to the central axis. The terminus portion has an opening in a direction perpendicular to the central axis. The inner diameter of the intermediate portion in the up-down direction is greater than the inner diameter of the distal end spatula portion. The vertebral body processing tool is rod-shaped and has a curved portion that curves downward along the central axis; when the foregoing is inserted into the vertebral body perforation guide from the terminus portion along the central axis and has passed the intermediate portion along the central axis, the distal end protrudes out from the opening of the distal end spatula portion. Provided is a safe therapeutic instrument that, in percutaneous vertebroplasty for a fracture or surgery to preventatively reinforce a vertebral body with bone cement, makes it possible to accurately excavate an intended location to every corner within the vertebral body while also minimizing incision in the skin.

The embodiment of the invention discloses a bone cement robot control method, a robot, equipment, a medium and a product, and belongs to the field of medical equipment. The method comprises the steps that image data and process parameter data are obtained, the image data comprise preoperative image data for a preset part of a target object and an intraoperative CBCT image at the current moment, and the process parameter data comprise one of the current injection rate and the current suction rate and current injection pressure data; the image data and the process parameter data are analyzed based on a pre-training machine learning model, control parameter data and state description data are obtained, and the state description data are used for describing the operation effect of the completed operation content; according to the control parameter data, an injection mechanism is controlled to execute bone cement injection operation or bone cement suction operation on the injured vertebra; and controlling the display device to display the state description data. According to the technical scheme, the consistency of the percutaneous puncture kyphoplasty effect can be improved.

The invention provides a puncture positioning device for unilateral percutaneous vertebroplasty and a using method thereof.The puncture positioning device is provided with a flat-strip-shaped rail, the left side of the top face of the rail is connected with a three-dimensional angle positioner capable of transversely moving and sliding, and the three-dimensional angle positioner is formed by combining an abduction angle positioning piece and a head inclination angle positioning piece; the head inclination angle positioning piece is connected to the abduction angle positioning piece in a sliding mode, a puncture catheter is arranged on an angle rotating and swinging piece of the head inclination angle positioning piece, and the abduction angle positioning piece and the head inclination angle positioning piece jointly position the abduction angle and the head inclination angle of the puncture catheter in a three-dimensional space; the left side of the bottom face of the rail is connected with a left supporting piece capable of transversely sliding. The right side of the track is provided with a right supporting piece capable of adjusting the supporting height. The puncture positioning device is simple to operate and convenient to adjust, can be fixed on the skin surface of a patient during use, is not easily influenced by the change of the body position of the patient, can accurately position the puncture abduction angle and the head inclination angle, and can accurately position and guide the puncture angle of a puncture needle.

The application provides a percutaneous vertebroplasty in-vitro puncture guider, and relates to the technical field of medical devices.The guider comprises a vertical guide rail and a sliding block capable of sliding up and down relative to the vertical guide rail.An angle adjusting plate in a circular arc structure is arranged on the sliding block and can rotate around a center point 0 under the guidance of the sliding block, and the center point 0 is located directly below the vertical guide rail.One end of the angle adjusting plate is provided with a clamping assembly for fixing a puncture needle.When the puncture needle is fixed on the clamping assembly, the puncture end of the puncture needle points to the center point 0.The application provides a percutaneous vertebroplasty in-vitro puncture guider, and the puncture needle can be placed into the guider, the accuracy of the puncture angle can be ensured, repeated adjustment due to a poor puncture angle can be avoided, the operation time is shortened, and the operation risk is reduced.
