The invention discloses a burn wound eschar abrading device for surgical debridement, which relates to the technical field of eschar abrading devices and comprises a shell, an arc eschar abrading surface fixed at the bottom of the shell, a motor arranged at the top of the shell and a partition plate fixedly connected in the shell. The scab abrading tool bit is exposed out of the scab abrading face and can adjust the contraction angle of the tool bit in a self-adaptive mode, the oil pressure control assembly contracts the scab abrading tool bit in a self-adaptive mode based on the radian of the wound scab, the scab abrading driving structure starts and stops rotation of the scab abrading tool bit through the oil pressure control assembly, and the dust collection assembly is fixed to the center of the bottom of the partition plate. The eschar abrading tool bits are distributed in the circular array and rotate oppositely in pairs, the rotating directions of the opposite eschar abrading tool bits are opposite, the eschar abrading tool bits counteract and reduce shaking of the skin and the wound eschar in the friction direction of the eschar abrading tool bits, continuous tearing between the wound eschar and skin tissue is effectively avoided, and the healing effect of the skin is improved. And the discomfort of the patient and the risk of secondary injury of the wound surface caused by tearing the connection between the wound surface scab and the tissue due to high-speed shaking are reduced.

The present invention relates to the technical field of medical devices, and specifically to a ligation clamp, comprising: a female plug body, on which a connected access channel and a ligation groove are provided, and a fine pipe can enter along the access channel and be accommodated in the ligation groove; a male plug body, which is plugged and matched with the female plug body to be movably accommodated in the ligation groove and the access channel, the head shape of the male plug body matches the ligation groove, and the head of the male plug body abuts against the side wall of the ligation groove to ligate the fine pipe; and a locking member, which is used to lock the male plug body at a predetermined position of the female plug body so that the head of the male plug body abuts against the side wall of the ligation groove. By dividing the ligation clamp into two parts, the female plug body and the male plug body, in the process of ligating the fine pipe, the ligation clamp does not need to be deformed, successfully avoiding the characteristic of the degradable magnesium alloy that is not easy to deform, so that the fine pipe can be effectively clamped.

The present invention relates to the technical field of rope replacement for hoists, and discloses a mine shaft hoist rope replacement device, comprising a plurality of sheaves, a capstan, and an old rope body that passes through the plurality of sheaves and the capstan in sequence, wherein the surface of the old rope body is respectively provided with containers A and B, and further comprising a frame body and a cross frame provided on the surface of the frame body, wherein the frame body and the cross frame are provided at the shaft opening of the shaft, a tensioning assembly provided on the surface of the frame body, the tensioning assembly comprising a fixed frame fixedly connected to the top of the frame body, a plurality of cylinders provided on the surface of the fixed frame, a connecting block fixedly connected to the output end of the cylinder, a tensioning wheel rotatably connected to the inner wall of the connecting block, and an adjusting assembly provided on the surface of the frame body. The present invention maintains a certain tension when a new rope is replaced by providing a tensioning assembly and an adjusting assembly, and at the same time, clamps the new rope with the help of a plurality of clamping blocks in the adjusting assembly and rotates with a rotating ring, so as to correct the misalignment and skewness phenomenon that occurs when the new rope is lifted with the old rope, and reduce the wear of the new rope by the sheave.

The invention relates to the technical field of bearing installation, and discloses a motor bearing positioning and installing device which comprises a rotating disc, the rotating disc is arranged in a bearing installing area, a driving assembly is arranged at the bottom of the rotating disc to enable the rotating disc to rotate, and placing tables used for placing parts are arranged on the upper edge of the rotating disc in a circumferential array mode. An oil injection device, a mechanical arm used for containing a bearing and a sleeve used for pressing the bearing are arranged in the moving direction of the containing table, a second guide rail and a first guide rail are arranged on the inner side and the outer side of the containing table respectively, and the first guide rail and the second guide rail are provided with moving assemblies with the same number. The moving assemblies can move on the first guide rail and the second guide rail, a limiting rope is connected between the moving assembly located on the first guide rail and the moving assembly located on the second guide rail, the limiting rope has elasticity, and when the moving assemblies on the first guide rail and the second guide rail have an angle difference, the limiting rope can generate an inclination angle.

The present application discloses a terminal, a terminal group and a connector assembly, wherein the terminal comprises a mounting section and a contact section located at one end of the mounting section, wherein the contact section is extended in a first direction and comprises a first surface, wherein a contact portion is provided on the first surface, and when a pair of the terminals are mated with each other, the contact portion of each terminal contacts the contact section of the other terminal, and the orthographic projections of the contact portions of the pair of terminals on a plane perpendicular to the first direction have no overlapping area. The terminal of the present application can realize smooth mating with each other, and can effectively reduce the elastic deformation of the terminal contact section during mating with each other, thereby reducing the need for the terminal contact section to resist amplitude drop, and can ensure a stable connection between the terminals.
