Abstract
The utility model discloses a kind of middle ear forceps, main includes dynamic pincers, fixed pincers, pincers bar, fastening spiral shell, pull end, spiral shell axis, rear lug, pull rod, dynamic pincers rear end connecting rod front end, pull rod is mounted in pincers bar, the fixed pincers of pincers bar front end connection, pincers bar connection spiral shell axis is simultaneously fixed by fastening screw-tightened, and spiral shell axis front is flexibly connected pull end, spiral shell axis rear portion is fixedly connected with rear lug, pull end front end connecting rod.The utility model structure is simple, can effectively increase the chucking power of jaw；Pincers rod rear end is to be put into nasal cavity simultaneously toward oblique bending shape convenient for this product and endoscope；When operation, not will cause pincers bar and endoscope wall wall in the work of pull end post-tensioning influences along mutual extrusion to endoscope visibility；Pull rod will not crush tissue when performing the operation running in pincers bar；It is convenient that mass production is manufactured, and is suitble to produce in enormous quantities.
Description
Technical field
The utility model relates to the fields of medical instrument, and in particular to a kind of middle ear forceps.
Background technique
Middle ear forceps belongs to earnose-throat instruments, is a kind of tool that doctor often uses during surgery.In operation
Surgical instrument in doctor's hand rescues the rope of people just as cliffside, its quality is directly related to the life security of patient,
And middle ear forceps is very delicate one kind in surgical instrument, its quality decides that can an operation go on smoothly.
The middle ear forceps used when operation at present, claw beam are all the biplate push rods combined using upper claw beam and lower claw beam, on
Claw beam and lower claw beam are to drive binding clip by pushing up and down.It is squeezed up and down when biplate push rod operates, using holding over time
Easily make the extrusion deformation in closure of push rod and binding clip.The joining place of the upper claw beam of biplate push rod and lower claw beam has the gap, and gap exists
It is easy to clip to tissue of patient when running up and down.
Utility model content
The purpose of the utility model is to overcome the shortcomings of the prior art, and provide a kind of middle ear forceps.
The purpose of this utility model is completed by following technical solution: this novel middle ear forceps, and main includes dynamic
Pincers, fixed pincers, pincers bar, fastening spiral shell, pull end, spiral shell axis, rear lug, pull rod, move pincers rear end connecting rod front end, and pull rod is mounted on pincers
In bar, the fixed pincers of pincers bar front end connection, pincers bar connection spiral shell axis is simultaneously fixed by fastening screw-tightened, before spiral shell axis front is flexibly connected
Handle, spiral shell axis rear portion are fixedly connected with rear lug, pull end front end connecting rod.The pincers rod rear end is oblique bending shape down.
The dynamic pincers and the clamping part surface clamped surely are designed with trapezoidal serrated face, and cooperation is stung up and down for dynamic pincers and fixed pincers
It closes.
The utility model has the following beneficial effects: the utility model structure is simple, the chucking power of jaw can be effectively increased；Pincers
Rod rear end is to be put into nasal cavity simultaneously toward oblique bending shape convenient for this product and endoscope；When operation, not in the work of pull end post-tensioning
Will cause pincers bar and endoscope wall wall influences along mutual extrusion to endoscope visibility；Pull rod is in pincers bar, Bu Hui
Tissue is crushed when operation running；It is convenient that mass production is manufactured, and is suitble to produce in enormous quantities.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the pull rod schematic diagram of the utility model.
Description of symbols: dynamic pincers 1, surely pincers 2, pincers bar 3, fastening spiral shell 4, pull end 5, spiral shell axis 6, rear lug 7, pull rod 8.
Specific embodiment
Detailed introduction is done to the utility model below in conjunction with attached drawing:
Embodiment: as shown in the picture, this middle ear forceps, main includes dynamic pincers 1, surely pincers 2, pincers bar 3, fastening spiral shell 4, pull end
5, spiral shell axis 6, rear lug 7, pull rod 8 move 1 rear end of pincers and rivet 8 front end of pull rod, and pull rod 8 is mounted in pincers bar 3, will not be transported in operation
As when crush tissue, the connection of 3 front end of pincers bar clamps 2 surely, dynamic pincers 1 and clamp 2 clamping part surface surely and be designed with trapezoidal serrated face, and
And move pincers 1 and surely about 2 cooperation occlusion of pincers.3 rear end of pincers bar is oblique bending shape down.Convenient for by the utility model and interior peeping
When mirror is put into surgery of nasal cavity simultaneously, and pincers bar 3 and endoscope wall wall are not will cause along mutually crowded in the work of 5 post-tensioning of pull end
It presses and influences to endoscope visibility.Pincers bar 3 connects spiral shell axis 6 and is tightened by fastening spiral shell 4, and the 6 front activity of spiral shell axis connects
Pull end 5 is connect, 6 rear portion of spiral shell axis is fixedly connected with rear lug 7, and spiral shell axis 6 can help pull end 5 to spring back, 5 front end connecting rod 8 of pull end.Work
When, rear lug 7 is fixed, and 5 post-tensioning of pull end, pull rod 8 is pushed forward, and moves pincers 1 and is closed with pincers 2 surely downwards.
It is understood that it will be understood by those skilled in the art that the technical solution of the utility model and utility model structure
Think of is subject to equivalent substitution or change all and should belong to the protection scope of the utility model the attached claims.
