Method and device for treatment of scaphoid fracture

PendingCN107854168ASolve technical problems that cannot be accurately inserted into the needleAccurate needle insertionSurgeryTransverse incisionDouble compression
The present invention provides a method and device for treating scaphoid fracture in the medical technology field, comprising the following steps: fixing the wrist joint in dorsiflexion position with a wrist fixation seat, determining trapezoid-scaphoid tubercle and marking ; Connect the sterilized auxiliary treatment device to the wrist fixation seat; make a 1cm transverse incision at the skin mark, separate the subcutaneous tissue until the scaphoid joint space; The guide sleeve pierces the surface of the distal pole of the scaphoid to lock the device; adjust the angle of the guide sleeve; use fluoroscopy to determine the direction of the sleeve, and confirm that the guide pin is inserted correctly; drive the anti-rotation Kirschner wire along the guide pin, remove Auxiliary treatment device; drill the guide pin into the distal end of the radius, and use a hollow drill to drill through the guide pin; double-ended compression screws pass through the guide pin and screw into the scaphoid; confirm the screw position again by fluoroscopy, and pull out the anti-rotation Kirschner wire , stop bleeding and suture the wound; the invention ensures accurate needle insertion and reduces the number of times of needle insertion and perspective.

Touch fingertip sensor and operating system and data processing method thereof

The invention relates to the technical field of tactile sensors, in particular to a tactile fingertip sensor and an operating system and a data processing method.The tactile fingertip sensor comprises a tactile skin, a mark array sticker and a monocular camera, the mark array sticker is pasted on the inner side of the tactile skin, and the bottom of the tactile skin and the bottom of the tactile fingertip sensor form a hollow cavity; the monocular camera is installed at the bottom of the touch fingertip sensor and located in the hollow cavity, and the vision field of the monocular camera covers the inner side of the touch skin. According to the touch fingertip sensor disclosed by the invention, when a mechanical finger wearing the sensor touches an object, the sensor shoots an internal mark array image through the monocular camera, inputs the internal mark array image to the upper computer for image processing and data analysis, and finally converts the internal mark array image into various touch information; comprise the deformation condition of the contact surface, the size and direction of pressure at each marked position, contact torque and the like. By means of the design, contact in different directions can be sensed, distributed touch information is provided, and it is guaranteed that the sensor is compact in structure and light in weight.
