Abstract
The invention discloses a kind of adjustable leg support hitch frames, including fore-stock, after-poppet, crossbeam, ankle fixing device；Opening angle between fore-stock and after-poppet is locked by first locking bolt at crossbeam both ends, and the height of fore-stock and after-poppet can be adjusted；There is reclinate segmental arc, segmental arc to put knee joint convenient for taking at the intermediate position of crossbeam；Ankle passes through the rubber ring of ankle fixing device, rubber ring to shrink, and pulls two flexible jacking blocks that ankle is wrapped fixation, then traction rubber ring, slide also move down downwards, after reaching precalculated position, it is locked with the second locking bolt, and then realizes the longitudinal traction to shank.The present invention can assist in the minimally invasive intramedullary nail Internal fixation technology of shin bone, the closed reduction of fracture of shaft of tibia operates, lower limb can be placed and be fixed, and by traction to shank distal and foot and multi-faceted, multi-angle adjusting, fracture of shaft of tibia end is resetted.
Description
Technical field
The present invention relates to a kind of Orthopedic medical instrument, more particularly to a kind of adjustable leg support hitch frame belongs to micro-
Create the assistive device field in tibial intramedullary nailing internal fixation operation, and in particular to place patient's leg in a kind of operation of fracture of shaft of tibia
Portion and the leg support hitch frame for foot being fixed traction.
Background technology
It is directed to the patient of tibial shaft closed fracture at present, it is conventional to implement closed reduction tibial intramedullary nailing internal fixation, art
Person is carrying out closed reduction, is expanding in marrow, intramedullary nail and screw merging operation, and assistant is needed to ajust shank distal and foot,
And maintain to draw, therefore assistant's heavy workload, and can not accomplish to continue and precisely operate.Existing shank towing bracket, design
It is heavy, be not easy to disinfection storage, and mostly metal makes, and influences to have an X-rayed, mostly based on support function, adjustability it is poor, and without holding
Continuous traction reduction function.Therefore, the fixation and positioning of leg can not be effectively performed in the structure of the prior art, and it is multiple to influence fracture
Position, to affect closed reduction tibial intramedullary nailing internal fixation surgical procedure, extends operating time.
Invention content
The present invention provides a kind of adjustable leg support hitch frames.
The present invention includes fore-stock, after-poppet, crossbeam, ankle fixing device；The material of fore-stock and after-poppet is carbon fiber
Dimension.
Hinged by the crossbeam at top between fore-stock and after-poppet, the opening angle between fore-stock and after-poppet is by cross
First locking bolt at beam both ends locks, and the height of fore-stock and after-poppet can be adjusted；The intermediate position of crossbeam, which has, to be turned under
Bent segmental arc, segmental arc put knee joint convenient for taking；
Ankle fixing device includes slide, guide tube, guide rod, the second locking bolt, rubber ring, flexible jacking block；Two cunnings
Seat is respectively sleeved on two struts of fore-stock, and slide can slide up and down adjusting on strut, and the position of slide is with the second lock
Determine bolt locking, guide tube is respectively and fixedly provided on the inside of two slides, rubber ring is located between two slides, and two guide rods are each passed through rubber
The outer segment activity of cushion rubber, guide rod is threaded through in guide tube, and the inside that guide rod is located in rubber ring is fixed with flexible jacking block.
The course of work of the present invention：
In progress fracture of shaft of tibia closed reduction intramedullary nail in fixed operation, suffering limb need to be supported, fixed operation,
Knee joint turn of bilge is taken to the segmental arc for being placed on crossbeam, shank is tilting in fore-stock, and ankle passes through rubber ring, rubber ring to shrink, and draws
Ankle is wrapped fixation by dynamic two flexible jacking blocks, and ankle needs to ajust foot before fixing, then downward traction rubber ring, slide
Also it moves down, after reaching precalculated position, is locked with the second locking bolt, and then realize the longitudinal traction to shank.
Beneficial effects of the present invention：
The present invention can assist in the minimally invasive intramedullary nail Internal fixation technology of shin bone, the closed reduction operation of fracture of shaft of tibia, energy
It is enough that lower limb are placed and fixed, and by traction to shank distal and foot and multi-faceted, multi-angle adjusting, to shin
Shaft fracture end is resetted.Shank proximal end intramedullary nail and medial and lateral screw is facilitated to be placed in operation simultaneously, the hitch frame is not in art
It influences perspective, can confirm surgical effect by image in art.
Description of the drawings
