Abstract
The utility model provides a telescopic T-shaped spanner used for orthopedic surgeries, and belongs to a spanner used for surgeries. The upper end of the T-shaped spanner is provided with a handle, a hexagon head is arranged at the bottom of the T-shaped spanner, and a long rod is arranged between the handle and the hexagon head. The handle comprises a handle sleeve and handle bodies, wherein the handle bodies are hinged to the two sides of the handle sleeve through pins. The long rod comprises an inner rod, an outer sleeve and elastic positioning device, wherein the inner rod is square, the elastic positioning device is connected to an end of the inner rod, square holes are formed in the outer sleeve and correspond to the inner rod in shape, a plurality of positioning holes are evenly distributed in the outer wall of the outer sleeve and communicated with the square holes, and the elastic positioning device is located on one side of the positioning holes. The elastic positioning device comprises a support column, a spring, a button and a positioning sleeve, wherein the support column is connected to the inner rod, the positioning sleeve is connected with the support column in a sleeved mode, the button is connected to the positioning sleeve in a sleeved mode, and the spring is arranged between the positioning sleeve and the support column. The telescopic T-shaped spanner has the advantages of being reasonable in structure, large in twisting force and wide in application range, the handle can be folded and collected inwards, the length of the T-shaped spanner can be adjusted, and the length of the spanner can be easily changed during the surgery so that the telescopic T-shaped spanner can meet the requirements of the surgery.
Description
Technical field
This utility model relates to a kind of operation scalable T shape spanner for spanner, particularly a kind of bone surgery.
Background technology
In surgical operation, operating theater instruments is varied, and operation is had to conclusive impact.The routine that pedicle screw in orthopaedics spinal operation and extremity fracture are used and locking nail, all need T shape spanner locked, and thus, T shape spanner is in current bone surgery, to use more a kind of instrument.At present the T shape spanner of each model is the bar of regular length, and the fracture running in clinical is varied, usually can run in the time tightening screw, and due to the relation of position, spanner is long or too short again, twists dead screw and becomes very difficult.In the time that pedicle screw is fixing, with twisting resistance spanner hold-down screw, when T shape spanner is locked, can run into equally because spanner is too short, T shape handle is blocked by the handle of twisting resistance spanner and cannot be locked.
Utility model content
The purpose of this utility model is that scalable T shape spanner for a kind of bone surgery will be provided, and solves existing T shape spanner too short, can not adapt to the problem of different operation demands.
The purpose of this utility model is achieved in that the upper end of this T shape spanner is handle, and bottom is turret head, between handle and turret head, has stock.
Described handle comprises: taper knob and handle, linked handle in the both sides of taper knob by pin.
Described stock comprises: bar, the outer bar of spanner and elastic positioner in spanner, and in spanner, bar is square, elastic positioner is connected to the end of bar in spanner; The outer bar of spanner has square opening, and described square opening is square corresponding with bar in spanner; In spanner, on the outer wall of bar, be evenly equipped with multiple locating holes, locating hole communicates with square opening, and elastic positioner is positioned at locating hole one side.
Described elastic positioner comprises: pillar, spring, button and positioning sleeve, and pillar is connected on interior bar, and positioning sleeve is socketed on pillar, and button is socketed on positioning sleeve, between positioning sleeve and pillar, has spring.
Beneficial effect: owing to having adopted such scheme, T shape handle connecting portion respectively has one 90 degree joint, when needed, can in folding, to reserve working place for other operating theater instruments.Middle part cross bar is divided into inside and outside two parts, and in near-end, bar connects spanner, is entity rectangle, and far-end is hollow, close contact when both connect, and in the time of work, strength can be stablized conduction.The end of proximal stem has an elastic button, is hollow design, and built-in spring has approximate number millimeter range of activity, and fixed bar is arranged at button bottom, prevents button shakiness, has reached the purpose of this utility model.
Advantage: rational in infrastructure, torsion is large, applied widely, the collapsible interior receipts of handle, T shape spanner adjustable in length, can easily change spanner length to adapt to operation needs in operation.
