摘要：
The utility model relates to medical equipment, namely to surgical instruments, and can be used in the oral cavity to collect a free gingival graft (SDT) from the sky and replant into the recipients necessary zone.The technical result of the claimed utility model is the creation of an ergonomic universal surgical instrument that provides good visualization of the donor area when collecting SDT, thereby allowing the use of standard surgical blades, in addition to U-shaped, for other surgical interventions.The essence of the proposed device is as follows. The working part of the device is 25 mm long, has universal fasteners 17 mm long, 1 mm wide and 2 mm thick with two notches for fixing the U-shaped blade and the possibility of fixing if necessary with a standard surgical blade. In the area of fixing the working and additional parts there are two technical cuts with a depth of 1 mm. The tool handle with a length of 85 mm, a width of 8 mm and a thickness of 4 mm has a grooved surface with a length of 70 mm with grooves of 0.5 mm and a step of 1 mm. Between the working part of the tool and the handle there is an additional space 35 mm long, tapering to the middle to 4 mm, and then again expanding to the working part up to 8 mm, in the middle of the transition point of the tool handle to the universal working there is a bend 30°. Narrowing and bending in this space between the working part and the handle is made to improve the visualization of the surgical field.Thus, a good visualization of the donor area for the intake of SDT is achieved by bending 30 ° at the transition point of the instrument handle to the universal working part. It is possible to insert into the universal working part both a U-shaped blade for intake of SDT, and a usual standard surgical blade, the ability to use of which is achieved through improved visualization. The device has an ergonomic knurled handle that provides ease of location in the hand and reduces slip. Thus, the tool greatly facili
