Description
Technical field
This utility model relates to a kind of multifunction traction positor, belongs to medical instruments field.
Background technology
In the time of the reduction therapy of near end of thighbone and fracture of shaft of femur, often need suffering limb to be kept at an angle or tilt outer inclined to one side, the interior inclined to one side tractive manner of inclination, traditional traction apparatus is because elasticity is larger, and can not realize traction angle and inclined traction, still adopts clinically at present traditional traction frame in conjunction with binding support bar, reach therapeutic effect, unusual inconvenience in operation, low precision, the more important thing is that reliability is bad, increase operation risk, extended operating time.
Utility model content
This utility model provides a kind of simple in structure, easy to operate, practical multifunction traction positor that has.
The technical solution of the utility model is as follows:
Multifunction traction positor is made up of holding screw (1), chuck (2), pin (3), draw bar (4), stable cover (5), locking pin (6), fixed block (7), bulb frame component (8), connection clip assembly (9), it is characterized in that: holding screw (1) afterbody has annular knurl; Chuck (2) fluting is for L shaped, and left end has screw hole, and right-hand member has screw, and has through hole perpendicular; There are step, screw thread in draw bar (4) end; Stable cover (5) end is cone structure, through hole, and right-hand member endoporus has screw thread; Fixed block (7) is Step Shaft, and left end endoporus is spherical.
Bulb frame (8) is made up of crossbeam (10), pin (3), pad (11), compact heap (12), bulb (13), overcoat (14); It is characterized in that: crossbeam (10) middle part is screwed hole, and two ends are stepped hole, and there is groove at two ends; Compact heap (12) interior bone, right-hand member is spherical pore; Bulb (13) left end is screw rod, and right-hand member is spherical, can 20 ° of pivot angles after assembling, 360 ° of rotations of hoop; Overcoat (14) outer wall is step-like, interior bone, and left end endoporus is taper hole, right-hand member outer wall is orthohexagonal.
Connect clip assembly (9) by connecting rod (15), bolt (16), connect folder (17), tighten handle (18) and form, it is characterized in that: connecting rod (16) left end has four screwed holes, right-hand member has blind hole, and outer wall is step-like; Connecting folder (17) end has four screw-threaded counterbore, and sidewall has T-shaped groove.
Multifunction traction positor is connected with extension table, suffering limb is connected with multifunction traction positor, implement traction operation.
Application XISHI heart draw bar makes product keep certain flexibility, in application, effectively avoided because of tractive dynamics is irregular and rigidity cross skeleton around the pull needle entry point causing when strong cracking, collapse skin, fall the appearance of the situations such as piece, and the effect of stablizing sleeve pipe be for traction frame on the basis with certain flexibility for tilting and enough intensity being provided when traction angle.
The inclination of product and angle adjustment realize by the bulb joint at middle part, can locate at any angle, have realized universal adjustment.
Traction frame adopts the T-shaped groove structure of quick change to be connected use with most of extension tables with the coupling part of extension table, is widely used.
The utlity model has advanced design, simple in structure, easy to operate, practical advantage, be suitable for Orthopedic Clinical and apply.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Multifunction traction positor is made up of holding screw (1), chuck (2), pin (3), draw bar (4), stable cover (5), locking pin (6), fixed block (7), bulb frame component (8), connection clip assembly (9), it is characterized in that: holding screw (1) afterbody has annular knurl; Chuck (2) fluting is for L shaped, and left end has screw hole, and right-hand member has screw, and has through hole perpendicular; There are step, screw thread in draw bar (4) end; Stable cover (5) end is cone structure, through hole, and right-hand member endoporus has screw thread; Fixed block (7) is Step Shaft, and left end endoporus is spherical.
Before traction operation, unclamp and tighten handle, the T-shaped groove that connects folder is placed on to the T-shaped of extension table to be connect on handle, screw and tighten handle, complete being connected of traction frame and extension table, unclamping outer sleeve can universally adjust the front end of traction frame, patient is on extension table, for the traction effect having reached, pull needle is as far as possible perpendicular to traction axis, determine pull needle entry point and squeeze into pull needle according to reduction of the fracture situation, unclamp the tight silk on chuck, after being hooked to pull needle, chuck uses tight silk locking, adjust traction angle, with the tight overcoat of hand-screw, determine traction state, tightly live overcoat with the spanner of adapted afterwards, implement traction operation.
