6 results about "Wound retractor" patented technology

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.

A surgical port includes an end face comprising a channel extending through the end face, the channel having a cross section shaped to receive a surgical instrument cannula, and a lateral wall extending around a perimeter of the end face, the lateral wall and end face enclosing an open volume. An end portion of a wound retractor is received in the open volume of the surgical port and in engagement with an inner surface of the lateral wall, and the surgical port is configured to abut a body wall in an inserted position of the wound retractor through the body wall.

Disclosed are medical devices for surgical procedures, especially procedures that involve the manipulation of surgical instrument end effectors close to the skin surface at an incision site. In accordance with some embodiments, an instrument access device is configured to couple to a wound retractor at a distal end of the device and to receive a multiple instrument entry guide in a port at the proximal end of the instrument access device, with an envelope between the distal and proximal ends defining a sealed cavity for maintaining insufflation pressure. Various embodiments provide means for rotating an assistant port in the envelope about a port that receives the instrument entry guide without twisting the envelope. Also disclosed are various envelope shapes. Also disclosed is an instrument entry guide that aligns surgical instrument shafts.

This application discloses a medical device for surgical procedures, particularly relating to procedures for manipulating the end effector of a surgical instrument near the skin surface at an incision site. According to some embodiments, an instrument access device is configured to be coupled to a wound retractor at a distal end of the device and to receive multiple instrument entry guides in a port at a proximal end of the instrument access device, wherein a sash is located between a distal and proximal end defining a sealed cavity for maintaining inflated pressure. Various embodiments provide means for rotating an auxiliary port in the sash about the port receiving the instrument entry guide without twisting the sash. Various sash shapes are also disclosed. An instrument entry guide aligned with the axis of a surgical instrument is also disclosed.

Medical devices for surgical procedures are disclosed, particularly procedures involving manipulation of a surgical instrument end effector proximate a skin surface at an incision site. According to some embodiments, an instrument access device is configured to couple to a wound retractor at a distal end of the device and receive a multi-instrument entry guide in a port at a proximal end of the instrument access device, with an envelope between a distal end and a proximal end defining a sealed cavity for maintaining a gas pressure. Various embodiments provide means for rotating an auxiliary port in the envelope around a port receiving an instrument entry guide without twisting the envelope. Various envelope shapes are also disclosed. An instrument entry guide that aligns a surgical instrument shaft is also disclosed.
