Description

Surgical retractor for rotator cuff repair Technical Field The invention relates to the technical field of medical instruments, in particular to a surgical retractor for rotator cuff repair. Background The rotator cuff repair surgical retractor is an important instrument in surgery, is mainly used for retracting tissues to expose surgical fields, is convenient for a doctor to operate, and when the handheld retractor is used, the doctor needs to grasp the correct holding posture, gently pulls the tissues, avoids tissue damage caused by excessive force, and adjusts the position of the retractor in time according to the progress of the surgery. When the automatic retractor is used, the automatic retractor is required to be accurately installed at an operation position, the angle and the tension are adjusted, so that the automatic retractor can stably retract tissues, and the automatic retractor has the main effects of retracting tissues such as skin and muscle of a shoulder, exposing a damaged position of a rotator cuff, providing a clear operation field for a doctor, facilitating the doctor to explore, cleaning the damaged tissues, implanting rivets, suturing and the like, and improving the accuracy and success rate of the operation. The traditional method mainly depends on passive spreading of a blunt drag hook or an arthroscope sleeve which is held by an assistant, has a series of inherent defects that the hand drag hook is easy to fatigue and shake to cause unstable operation vision, and after the drag hook is fixed in position, if the angle of the vision is required to be adjusted, the drag hook is always taken out completely and placed again, the operation flow is forced to be interrupted, and the efficiency is low. When repairing posterior or giant rotator cuff tears, it is difficult for existing tools to provide multi-angle, dynamic exposure. Stable retraction is highly dependent on an experienced assistant to maintain concentration and fixed posture throughout the process, is labor-intensive, and presents a risk of communication errors. In complex or long-term surgery, assistant state fluctuations can directly affect the safety and accuracy of the operation of the doctor of the main knife. The function is single, and the dynamic adaptability is lacking, the existing drag hook is mostly of static design, and once the drag hook is placed in the drag hook, the pulling direction and the pulling range of the drag hook are fixed. The retraction angle cannot be finely adjusted under the condition that an instrument is not required to be taken out so as to meet the unique visual angle requirements when different tendon footprints are sutured or knotted, and the fineness and flexibility of the operation are limited. Disclosure of Invention In view of the problems that the hand-held drag hook in the prior art is unstable in shake and cannot finely adjust the angle after traction, the surgical drag hook for rotator cuff repair is provided. The application provides a surgical retractor for rotator cuff repair, which aims to: through setting up the drag hook pole with pedal inflating pump control, make medical personnel can realize carrying out the drag hook extension to patient tissue region under the circumstances of no outsider help, and drag hook in-process is comparatively stable, help the stability of operation field of vision, through setting up a plurality of drag hook rings, when need to adjust the angle after the retractor, can pack up one of them drag hook pole earlier and carry out the position adjustment, the position to a plurality of drag hook poles is adjusted in proper order to the reciprocal, just can realize the angle and the adjustment of scope to the tractive, the fineness and the flexibility of effectively improving the operation in-process. The surgical retractor for rotator cuff repair comprises a first retractor ring and a retractor unit arranged on the inner wall of the first retractor ring, wherein the retractor unit comprises a universal component arranged on the inner wall of the first retractor ring; The universal component comprises a second pull hook ring arranged on the inner wall of the first pull hook ring, a third pull hook ring arranged on the inner wall of the second pull hook ring and a fourth pull hook ring arranged on the inner wall of the third pull hook ring, and the second pull hook ring, the third pull hook ring and the fourth pull hook ring are all rotatably arranged on the corresponding inner wall through damping bearings; The upper ends of the first pulling hook ring, the second pulling hook ring, the third pulling hook ring and the fourth pulling hook ring are all provided with expansion components, the expansion components on the multiple pulling hook rings are respectively used for carrying out drag hook expansion on tissues in different directions, and the multiple pulling hook rings are free to rotate and do not influence each other and are used for driving angl
