Description

Incision tractor for orthopedic operation

Technical Field

The invention relates to the technical field of medical instruments, in particular to an incision retractor for orthopedic surgery.

Background

Orthopedics is one of the most common departments in various hospitals, and mainly researches the anatomy, physiology and pathology of the skeletal muscle system, and maintains and develops the normal form and function of the system by using medicines, operations and physical methods.

With the change of the times and society, the orthopaedics trauma spectrum has obvious change, for example, the diseases such as bone joint tuberculosis, osteomyelitis, poliomyelitis and the like are obviously reduced, and the trauma caused by traffic accidents is obviously increased. Bone science is a specialty or discipline of medicine that specifically studies the anatomy, physiology, and pathology of the skeletal muscle system, uses pharmaceutical, surgical, and physical methods to maintain and develop the normal morphology and function of the system, and treats injuries to the system. Orthopedics is also known as orthopedics. Is a specialty or discipline of medicine, specially researching the anatomy, physiology and pathology of skeletal muscle system, using medicine, operation and physical method to maintain and develop the normal form and function of said system, and curing the wounded operation of said system, referring to the doctor using medical equipment to make excision, suture and other treatments on the patient's body. The health of the patient is maintained by the operation of the knife, the scissors, the needle and other instruments on the local part of the human body. Is the main treatment method of surgery and is commonly called as "open operation". The purpose is to cure or diagnose diseases, such as removing pathological tissues, repairing injuries, transplanting organs, improving functions and morphology of organisms, and the like. Early surgery was limited to simple manual procedures for cutting, incising, suturing, such as abscess drainage, tumor excision, traumatic suturing, etc., on the body surface. Surgery is a procedure that disrupts tissue integrity (dissection) or restores tissue with its integrity disrupted (suturing). With the development of surgery, the surgical field is expanding continuously, and the surgery can be performed on any part of the human body. The applied instruments are also updated continuously, such as a plurality of surgical knives, namely electric knives, microwave knives, ultrasonic knives, laser knives and the like.

The existing incision traction device for the orthopedic operation can only draw and expand the incision at a fixed position during the orthopedic operation, can not timely adjust the size of the incision along with the actual needs in the operation, is inconvenient to retract and release the incision clamping device while being excessively complicated in operation, occupies too much space and is not tidy to put.
