Abstract
The invention discloses a surgical indirect repositor for bone fracture. The surgical indirect repositor comprises bone nails, a connecting rod and an open driving mechanism, wherein the bone nails are respectively used for fixing two sections of bones; the connecting rod is used for connecting the bone nails at the two sides; and the open driving mechanism is used for driving the bone nail at one side to move so as to open the bone fracture position, and comprises a rack connected with one end of the connecting rod, a gear meshed with the rack, and a rocker connected with the gear. The surgical indirect repositor has the advantages that the structure is simple, the use is convenient, the time and the labor are saved, the bone fracture position can be effectively opened, the repositioning effect is good and the damage to the bones is reduced and the like.
Description
Technical field
The invention belongs to operating theater instruments, especially relate to a kind of operation with the fracture indirect restorer.
Background technology
At present, in reduction of the fracture fixing operation, the general two ends of adopting traction indirectly or directly holding fracture with apparatus retract its fracture.But in practical operation, the very inconvenience of employing aforesaid way is wasted time and energy, often can't effectively strut, and big to the bone infringement, cause skeleton soft tissue on every side to be peeled off easily, bone place blood circulation is not good, thereby influences symphysis.
Summary of the invention
Technical problem to be solved by this invention provides a kind of operation with the fracture indirect restorer, and what help fracturing struts and reset, and is convenient to reset in the art fixing and reduces the influence to bone surrounding soft tissue and blood.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of operation comprises the nail, the connecting rod that is used to connect the both sides nail that are respectively applied for fixing fracture two-section bone, is used to drive side seam nail and moves to strut the driving mechanism of fracture with the fracture indirect restorer, strut driving mechanism comprise the tooth bar that links to each other with connecting rod one end, with tooth bar meshed gears, the rocking bar that links to each other with gear.
Said connecting rod has between several sections, the several sections connecting rods continuous through Movable joint respectively.
Said Movable joint comprises and horizontally rotates joint and vertical rotary joint.
Link to each other through Movable joint between said connecting rod and the tooth bar.
Said Movable joint is for horizontally rotating joint or vertical rotary joint.
Be installed with locating piece respectively on the nail of said both sides, wherein a side locating piece and this side connecting rod one end fix through bolt, and the opposite side locating piece links to each other with rocking bar, and moves along tooth bar with gear.
Adopt operation of the present invention with the fracture indirect restorer, have following advantage:
1, simple in structure, easy to use, time saving and energy saving;
2, can effectively strut bone fracture place, better reduction;
3, help reducing the infringement to bone, minimizing is peeled off skeleton surrounding soft tissue, protects blood circulation to greatest extent.
Description of drawings
Be elaborated below in conjunction with accompanying drawing and specific embodiment the present invention:
Fig. 1 is structure of the present invention and uses sketch map.
Fig. 2 is a schematic top plan view of the present invention.
The specific embodiment
Like Fig. 1-shown in Figure 2; Operation of the present invention comprises the nail 2, the connecting rod 3 that is used to connect both sides nail 2 that are respectively applied for fixing fracture two-section bone 1, is used to drive side seam nail 2 and moves strutting the driving mechanism of fracture with the fracture indirect restorer, this strut driving mechanism comprise the tooth bar 4 that links to each other with connecting rod 3 one ends, with tooth bar 4 meshed gears 5, the rocking bar 6 that links to each other with gear 5.Concrete connected mode is for being installed with locating piece 7 respectively on both sides nail 2, wherein a side locating piece 7 fixes through bolt 8 with these side connecting rod 3 one ends, and opposite side locating piece 7 links to each other with this side rocking bar 6, and moves along tooth bar 4 with gear 5.So,, can drive this this side seam nail 2 of locating piece 7 drives and move to the right, move to right, realize strutting of fracture thereby also just drive right side this section bone 1 through shaking 5 rotations of rocking bar 6 driven gears.In addition, connecting rod 3 is designed to have between several sections structure, several sections connecting rods 3 links to each other through Movable joint respectively.Said Movable joint comprises and horizontally rotates joint 9 and vertical rotary joint 10.So, can realize level or buckling between each section connecting rod 3, to satisfy the demand that struts of different fracture directions.Fig. 1, the connecting rod shown in 23 are two sections, link to each other through horizontally rotating joint 9 therebetween.Certainly, also can link to each other through Movable joint between connecting rod 3 and the tooth bar 4, this Movable joint can be adopted and horizontally rotate joint 9 or vertical rotary joint 10, Fig. 1, has promptly adopted vertical rotary joint 10 shown in 2.Can realize through tightening modes such as pin 11 and the anglec of rotation of Movable joint is fixing.
Operation of the present invention is with the fracture indirect restorer; Simple in structure, easy to use; Time saving and energy saving, can avoid directly holding bone 1 and the infringement to bone 1 of initiation, reduced peeling off to skeleton surrounding soft tissue; Protect blood circulation to greatest extent, satisfied the demand of reduction of the fracture fixing operation.
But; Those of ordinary skill in the art will be appreciated that; Above embodiment is used for explaining the present invention; And be not to be used as qualification of the present invention, as long as in connotation scope of the present invention, all will drop in claims scope of the present invention variation, the modification of the above embodiment.
