Abstract
The utility model discloses a tendon pushing device which comprises a support body. The support body is provided with a main pulley and two auxiliary pulleys. The auxiliary pulleys are located on the two sides of the main pulley, and a certain inclined angle alpha is formed between the main pulley and each auxiliary pulley. The tendon pushing device is characterized in that the main pulley and the auxiliary pulleys are connected through positioning pin shafts, and the positioning pin shafts are connected with the support body in a rotating mode. The tendon pushing device has the advantage of being free of damage to tendons.
Description
Technical field
This utility model relates to a kind of medical apparatus, particularly a kind of tendon device that pushes away.
Background technology
Tendon is strand or the membranaceous dense connective tissue at belly of muscle two ends, is convenient to muscle and adheres to and fix.The tendon of a muscle divides on the different bones that are attached to two or more than two, is that the draw due to tendon just can make the contraction of muscle drive the motion of different bones.Each piece skeletal muscle all is divided into belly of muscle and tendon two parts, and belly of muscle consists of muscle fiber, and the red matter of color is soft, and contractility is arranged, and tendon consists of dense connective tissue, and color is harder in vain, there is no contractility.Tendon is attached to skeleton to skeletal muscle.
In quantity of motion, during excessive or contingency, tendon tends to produce fracture, this with regard to needs operation sewed up or repaired.
Under carrying out arthroscope, during knee surgery, often have the tendon ligament need to pass through the bone road, often bone road opening part bone is more sharp-pointed, tendon by the time easily impaired, cause secondary damage.
Summary of the invention
When being to provide a kind of the operation, the purpose of this utility model can not damage the operation on tendon of tendon with pushing away the tendon device.
In order to achieve the above object, the technical solution of the utility model is: a kind of tendon device that pushes away, comprise support body, described support body has head pulley and two auxiliary pulley, auxiliary pulley the both sides of head pulley and and head pulley between form certain inclined angle alpha, its innovative point is: between described head pulley and auxiliary pulley, by alignment pin, be connected, alignment pin and support body are rotationally connected.
Inclined angle alpha between described head pulley and auxiliary pulley is obtuse angle.
This utility model is connected by alignment pin due between described head pulley and auxiliary pulley, and alignment pin and support body are rotationally connected.When being performed the operation, the tendon of fracture can be carried out to tractive by head pulley, head pulley is rotated with respect to support body, and tendon also stretches thereupon, not only can not damage tendon, but also play the purpose of auxiliary pulling.
The accompanying drawing explanation
The embodiment provided below in conjunction with accompanying drawing is described in further detail this utility model.
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of tendon device that pushes away, comprise support body 1, described support body 1 has head pulley 2 and two auxiliary pulley 3, auxiliary pulley 3 the both sides of head pulley 2 and and head pulley 2 between form certain inclined angle alpha, its innovative point is: between described head pulley 2 and auxiliary pulley 3, by alignment pin 4, be connected, alignment pin 4 is rotationally connected with support body 1.
As shown in Figure 1, the inclined angle alpha between described head pulley 2 and auxiliary pulley 3 is obtuse angle.In use, Caton phenomenon in the time of can not producing the tendon tractive, prevent tendon injury.It is for well between 120 ° ~ 135 ° that this utility model can adopt inclination angle.
This utility model, when being performed the operation, can carry out tractive by head pulley by the tendon of fracture, and head pulley is slided with respect to support body, and tendon also stretches thereupon, not only can not damage tendon, but also play the purpose of auxiliary pulling.
Claims (2)
