Description

Dental spherical attachment female part replacement device Technical Field The utility model belongs to the technical field of dental instruments, and particularly relates to a dental spherical attachment female part replacement device. Background The dental spherical attachment is a precision attachment for dental restorations, consisting of a spherical male part and a female part adapted thereto, the female part spherical cap being an important component of the female part. In the whole attachment system, the spherical cap of the female part is tightly matched with the male part (spherical), is positioned on one side of the tissue plane of the base of the denture, interacts with the male part on the abutment, and plays a key role in retention. When the dentist or dentist technician changes the spherical cap which is seriously lost in elasticity or abrasion, the changed spherical cap is placed in the clamping groove of the female part, and because the volume of the spherical cap is smaller, when the spherical cap is changed by using forceps or other tools, the replacement dislocation easily occurs, the internal structure of the spherical cap is easily damaged, and when the placement position is inaccurate, the retention force of the spherical cap is influenced, and the time and the material consumption are consumed. Disclosure of utility model In order to solve the above problems, the present utility model provides a dental spherical attachment female member replacement device. The utility model is realized in the following way: the utility model provides a dental spherical attachment female part changing device, includes the connecting rod, connecting rod one end be provided with the screw operating handle, the top of screw operating handle is provided with the bulb, bulb and the high fit of spherical cap attachment female part can shift with changing the device to ensure its accuracy, reach perfect effect, screw operating handle increases the frictional force between hand and the handle, and difficult the skid facilitates the use, the diameter of bulb is greater than the internal diameter 0.1-0.2mm of dental spherical attachment female part spherical cap, the internal diameter of dental spherical attachment female part spherical cap is 1.6mm, the diameter of bulb is 1.7-1.8mm, bulb and screw operating handle junction's diameter be 0.5-0.6 times of bulb diameter, and through R0.2-0.3 mm circular arc chamfer smooth transition bulb diameter slightly greater than the internal diameter of spherical cap, place the spherical cap after the recess of spherical attachment female part in the convenient operation, with the bulb is placed the spherical cap from the spherical cap to be installed to the spherical cap, install the diameter is 0.5-0.6 times of spherical cap diameter and the smooth diameter of spherical cap is the diameter of spherical cap, and the diameter of spherical cap is the smooth diameter is the diameter of 0.5-0.3 mm of spherical cap is convenient after the spherical cap is installed to take out. The ball head and the threaded operation handle are made of stainless steel, the surface roughness of the ball head is Ra0.4-Ra0.6mu m, the roughness is moderate, when the surface roughness is smaller than Ra0.4mu m, the surface is too smooth, the ball head and the ball head can slide easily when being matched, the accurate operation is not facilitated, when the surface roughness is larger than Ra0.6mu m, the ball head can not be taken out of a ball groove easily, the length of the threaded operation handle is 3-4cm, the length is moderate, the hand is convenient to hold, the surface roughness is Ra0.6-Ra0.8mu m, the hand slip is avoided, meanwhile, the roughness is not felt, the damage to the skin of the hand is avoided, the outer side of the threaded operation handle is provided with an arc chamfer of 1-1.5mm, and the comfort level is improved when the hand is held.
