Surgical retractor and detachable clamp assembly used for retractor

The set of inventions relates to medical devices, in particular to surgical retractors and wound retractors for displacing and securing anatomy of a surgical incision in a given position during surgery to provide access to a surgical region of a patient's body. A removable clip for a surgical retractor, made as an L-shaped curved member, includes a base provided with a device for fixation in a surgical retractor and a microsurgical instrument recess, and a pair of teeth for holding an anatomical structure. The toothing is configured as a profiled plate with a working area widening to ensure contact with the anatomical structure, the widening being formed by a raised pad located at least on the inner and / or outer end edge side of the lower end of the plane of the toothing plate. The included angle between each tooth part and the plane of the base is smaller than 90 degrees, and therefore gaps used for passing of microsurgical instruments are formed between the tooth parts. The surgical retractor comprises a frame with a rack carrying a fixed arm and a movable arm, the fixed arm and the movable arm being hingedly connected to a retainer for the detachable clip, where the retainer is configured to receive at least one of the aforementioned detachable clips. A removable clip assembly for a surgical retractor includes at least one central dual tooth removable clip; the at least one peripheral double-tooth detachable clamp is constructed to be capable of accommodating the central double-tooth clamp between the tooth parts of the central double-tooth clamp; and at least one central single-tooth detachable clamp. The use of the invention provides an increased working space and a higher degree of freedom of surgical instrument operation, enabling access to the lateral region of the operated structure during surgery without extending the skin incision.

Wound retractor

The application discloses a wound puller and belongs to the field of medical supplies. The wound puller comprises a wound pulling unit, a first pull strip and a second pull strip which are arranged oppositely and whose central axes are located on the same vertical plane, a skin sticking unit fixedly connected with the first pull strip on one side and a skin sticking unit fixedly connected with the second pull strip on the other side, a guide hole in the free end of the first pull strip for the second pull strip to pass through, and a fixing device arranged on the adjacent contact surface of the first pull strip and the second pull strip. The first pull strip and the second pull strip have a first state of relatively freely moving along the axis direction of the guide hole under the constraint of the guide hole and a second state of fixing the relative position of the first pull strip and the second pull strip after the fixing device fixes the upper and lower overlapping parts. In the process of bidirectional pulling and closing, the stress direction is basically on the same horizontal line, and the fixed position is the overlapping part in the middle of the pull strips. In this way, the suture force can be symmetrically transmitted along the middle, so that the force is evenly distributed to the skin sticking units on the two sides.
