Description
Technical field
This utility model belongs to technical field of medical instruments, relates to a kind of universal handle clamping neurosurgery microinstrument.
Background technology
Microscopic needle is the medical apparatus and instruments often used in Minimally Invasive Surgery.When performing the operation, general employing needle holder clamps microscopic needle and carries out surgical anatomic operation.Needle holder volume is large, easily stops the visual field, is unfavorable for that Minimally Invasive Surgery operates.But existing also do not have a kind of be specially adapted to carry out in Minimally Invasive Surgery holding this kind of apparatus of microscopic needle device occur.
Utility model content
The purpose of this utility model is to provide a kind of universal handle clamping neurosurgery microinstrument, is applicable to Minimally Invasive Surgery, conveniently can hold microscopic needle, improves procedure efficiency.
The technical scheme that this utility model adopts is, the universal handle of clamping neurosurgery microinstrument, comprise handle, handle inner surface is helicitic texture, handle front end is connected with screw flight, screw rod is provided with nut, the front end of screw rod is provided with bayonet socket, bayonet socket is rear wide front narrow circular platform type structure, 3 blocks of fan-shaped metal derbies are longitudinally distributed in bayonet socket, and be provided with spring between 3 metal derbies, metal derby is rear wide front narrow structure, the structure of metal derby matches with bayonet socket interior shape, and the rear end of 3 metal derbies is contacted foremost by pad and screw rod.
Feature of the present utility model is also, the end of handle is set to rifle bayonet fittings.
Handle is provided with graininess projection.
The beneficial effects of the utility model are, drive screw rod by rotary nut, promote pad and metal derby, make the Distance Shortened between metal derby or expansion, lock whereby or unclamp bayonet socket front end.Handle tail end is arranged to bayonet shape, avoids blocking surgical field of view; Handle is provided with graininess projection, is convenient to rotation process.
Accompanying drawing explanation
Fig. 1 is the universal handle structural representation of this utility model clamping neurosurgery microinstrument.
Fig. 2 is the structural representation of bayonet socket inside.
In figure, 1. handle, 2. screw rod, 3. metal derby, 4. spring, 5. bayonet socket, 6. graininess is protruding, 7. nut, 8. pad.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in detail.
The universal handle of this utility model clamping neurosurgery microinstrument, structure as shown in Figure 1, comprise handle 1, be helicitic texture in handle 1, handle 1 front end is threaded with screw rod 2, screw rod 2 is provided with nut 7, the front end of screw rod 2 is provided with bayonet socket 5, bayonet socket 5 is rear wide front narrow circular platform type structure, 3 blocks of fan-shaped metal derbies 3 are longitudinally distributed in bayonet socket 5, as shown in Figure 2, spring 4 is provided with between 3 metal derbies 3, metal derby 3 is rear wide front narrow structure, the structure of metal derby 3 matches with bayonet socket 5 interior shape, the rear end of 3 metal derbies 3 is contacted foremost by pad 8 and screw rod 2.The end of handle 1 is set to the bending structure of " bayonet shape ", handle 1 is provided with graininess projection 6.
The universal handle of this utility model clamping neurosurgery microinstrument, drives screw rod 2 by rotary nut 7, promotes pad 8 thus promote 3 metal derbies 3, making the Distance Shortened between metal derby 3 or expansion, lock whereby or unclamp bayonet socket 5 front end.Because bayonet socket 5, metal derby 3 are rear wide front narrow structure, metal derby 3 can be made mobile in bayonet socket 5 by promoting pad, the spring of setting makes to keep tension force between each metal derby 3.Handle 1 tail end is arranged to bayonet shape, avoids blocking surgical field of view; Handle 1 is provided with graininess projection 6, is convenient to rotation process.
This utility model reasonable in design, easy and simple to handle, the microscopic needle of all size can be clamped, use of repeatedly sterilizing, cheap, alleviate the financial burden of patient, also mitigate the work difficulty of staff simultaneously, improve the efficiency of operation technique.
