Separated-type double-end completely-adjustable abdominal retractor

Abstract

The invention discloses a separated-type double-end completely-adjustable abdominal retractor which comprises a retractor body. The separated-type double-end completely-adjustable abdominal retractor is characterized in that the retractor body is composed of a first retractor draw hook and a second retractor draw hook; certain ends of the first retractor draw hook and the second retractor draw hook are fixedly connected with a retractor drawbar, and the other ends of the first retractor draw hook and the second retractor draw hook are hook-shaped. The separated-type double-end completely-adjustable abdominal retractor is novel in design, practical, and beneficial to operation; the depth and direction changes of the retractor can be determined according to operation demands and the sizes and pulling-opening degrees of incisions of patients, and the fixation azimuth and pull strength of the retractor can be adjusted at will; traction is stable, the defect that exposure of an operation visual field is influenced by frequent unhooking caused by manual traction is avoided, and the labor and operation time are greatly saved; the separated-type double-end completely-adjustable abdominal retractor is convenient to sterilize and carry, can be popularized and generalized in both large-scale general hospitals and rural health centers, and is quite ideal in effect.

Description

technical field [0001] The invention relates to a retractor for abdominal surgery, in particular to a separated double-head fully adjustable abdominal retractor, which belongs to the technical field of medical devices. Background technique [0002] The implementation of abdominal surgery, such as partial hepatectomy, pancreaticoduodenectomy, splenectomy and portal azygos devascularization, cannot do without the use of abdominal retractor. Although the existing abdominal retractors have replaced the manual pulling of the second and third assistants in the past, saving a certain amount of time and physical strength, they still have certain defects, such as the fixed size and shape of the retractors, which limit the The surgeon adjusts the angle and orientation of the retractor according to the needs of the operation and the difference in the surgical field of view, which makes the exposure of the surgical field of view limited and inconvenient to adjust; some retractors have m...

Problems solved by technology

However, the hand-type retractors for exposed instruments used in surgery are the most commonly used. When pulling with retractors, since the retractors are mostly in point contact with the edge of the surgical incision, usually each retractor can only pull out a triangular shape. Field of view, in order to achieve a wider surgical field of view, multiple hands and multiple hooks are required to pull multiple points on the edge of the surgical incision at the same time, but such an operation is time-consuming, laborious, and very inconvenient

[0004] Although there are some devices on the market at present, these devices are scattered and self-made, resulting in poor adjustment performance of the retractor during the use of the device, which cannot be firmly fixed, which in turn makes the muscle pulling force smaller when retracting. And sometimes because the retractor is too large, it affects the surgical field of view, which is inconvenient for clinical use, time-consuming and laborious, reduces the stability of the surgical operation, affects the smooth progress of the surgical operation, reduces the operation efficiency, prolongs the operation time, is inconvenient for the operation, and is limited in popularization and application.
