The invention discloses a probe and method for probing a bony channel in sacroiliac screw implantation, and relates to the technical field of orthopedic surgical instruments, the probe comprises a hollow screw and a probe, the front end of the hollow screw is provided with a self-tapping part, the hollow screw is axially provided with a through hollow channel, and the hollow channel allows the probe to pass through; the probe comprises a rod body, a spherical head and a handle, and the spherical head is connected with the handle through the rod body. According to the hollow screw placement structure and method with the probe capable of feeding back the position of the bone channel in the sacrum, the spherical head of the probe can slide along the interior of the bone cortex of the sacrum after entering the sacrum, so that the situations that the bone channel of the hollow screw is irregular and narrow due to high-energy damage or sacrum dysplasia are prevented; therefore, the hollow screw penetrates out of the bone cortex, and serious nerve and blood vessel injury is caused. The probe technology not only can improve the operation safety and efficiency, but also can reduce the number of times of fluoroscopy in the operation.

The present disclosure relates to a tank configured to hold a pressurized substance. The tank includes a chamber (110) configured to enclose the pressurized substance and provide a seal between the pressurized substance and an ambient atmosphere, and an endoskeleton (120) disposed within the chamber (110) and coupled to the chamber (110) to provide structural support for the chamber (110). The endoskeleton (120) includes a plurality of coupled support members (130). The plurality of coupled support members (130) includes at least a first set (131) of support members having sides formed by a plurality of sheets. Each support member in the first set (131) has an internal asymmetric tetrahedron structure formed by the sides. Each face of the asymmetric tetrahedron structure is in the shape of a scalene triangle.

This invention discloses a variable stiffness soft gripper and its working method, belonging to the field of soft manipulator technology. The invention includes a driving layer and a base layer arranged vertically. A cooling cavity is formed within the base layer, and a flexible covering layer is provided within the cooling cavity. A composite endoskeleton and a heating component are provided within the flexible covering layer, and the endoskeleton is filled with a phase change material. The composite endoskeleton includes a connecting component and several bone segments spaced apart along the extension direction of the connecting component. Filling spaces are formed between adjacent bone segments. This invention employs a flexible, segmented composite endoskeleton, allowing the phase change material to preferentially flow into and fill the filling spaces between the bone segments after the gripper bends. After cooling, a segmented locking structure is formed, thereby transforming the gripping load from a bending and torsional load borne entirely by the phase change material into a force form mainly based on compression and limiting between segments, which can more effectively improve the gripper's stiffness retention and load-bearing stability.

The invention relates to the technical field of bushings, in particular to a bushing machining method and a bushing. The machining method of the bush comprises the steps that the outer framework and the inner framework are manufactured; under the state that the outer framework is manufactured, the diameter of the peripheral surface of the outer framework is a first preset diameter; on the basis that the outer framework and the inner framework are manufactured, the outer framework and the inner framework are placed in a vulcanization mold, and the outer framework is arranged on the outer side of the inner framework in a sleeving mode; positioning the outer framework and the inner framework in the vulcanization mold, injecting a sizing material into the vulcanization mold, and curing between the outer framework and the inner framework through a vulcanization process to form an elastic layer; and on the basis that the vulcanization process is completed, contractility is applied to the peripheral face of the outer framework till the diameter of the peripheral face of the outer framework is contracted to a second preset diameter, and machining of the bush is completed. Therefore, the problem that the bushing is easy to damage due to large tension degree is solved.

The invention relates to the technical field of human face model inner skeletons, and provides an adjustable human face model inner skeleton device which comprises an inner skeleton body which can be installed in a human face model and comprises a horizontal direction adjusting mechanism and a vertical direction adjusting mechanism. The horizontal direction adjusting mechanism and the vertical direction adjusting mechanism can stretch out and draw back in the length direction of the internal skeleton body, and the vertical direction adjusting mechanism is installed on the horizontal direction adjusting mechanism in a sliding mode. The two ends of the horizontal direction adjusting mechanism in the length direction are in contact with the two sides of the face model in the width direction respectively, and the bottom end of the vertical direction adjusting mechanism is in contact with the lower side of the face model. The size of the face model can be adjusted at any time, the accurate face model can be obtained, the structure is simple, and manufacturing is easy.

This invention provides an endoskeleton pneumatic soft robot, comprising: a helical pneumatic soft body, two anchoring components, and a pneumatic drive unit connected to the pneumatic soft body. The pneumatic soft body includes a strip-shaped flexible covering structure capsule and a flexible endoskeleton. The flexible endoskeleton is a spring, and the flexible covering structure capsule wraps around the spring's inner cavity along the spring's helical path. The two ends of the flexible covering structure capsule are an open end and a closed end, respectively. The end of the pneumatic soft body near the open end of the flexible covering structure capsule is a fixed end, and the other end of the pneumatic soft body is a free end. The two anchoring components are respectively connected to the fixed end and the free end of the pneumatic soft body. This invention can significantly reduce deformation waiting time, completing structural elongation within seconds, making it suitable for situations requiring rapid deployment. Furthermore, while ensuring deformability, it is smaller and more compact, making it more suitable for space-constrained operating environments.

Surgical guide development based on anatomical surface topology analysis includes determining surface shape variability of a surface of bony anatomy in a region of interest, generating, based on the surface shape variability, a digital guide design of a proposed surgical guide for use against the bony anatomy during a surgical procedure, the generating determining placement and surface coverage for the proposed surgical guide and configuring the proposed surgical guide to have a corresponding footprint and guide features configured to interface with selected features of the surface of the bony anatomy, rating the proposed surgical guide for use against the bony anatomy during the surgical procedure by performing, using the digital guide design, an automated topology-based stability assessment to produce a performance rating for the proposed surgical guide, determining whether the performance rating for the proposed surgical guide satisfies a predefined performance rating threshold, and performing processing based on that determination.
