ABSTRACT:
This invention relates to a device and method for use in transcutaneous surgical procedures, such as transcutaneous catheterization and surgical biopsy.
To provide that the operative parts of instrumentation to be introduced into the patient's body are shielded from contact with the patient's skin, and thereby to inhibit transfer of micro-organisms from the skin into the body, there is provided a transcutaneous indwelling shield device for insertion into a skin aperture, comprising a transcutaneous distal portion providing an instrument access port, connecting to a proximal portion of shallow dished form of substantially greater dimension than said access port, the proximal portion tapering inwardly to said distal portion to readily guide the distal tip of the instrument to said access port. The distal portion serves as a wound retractor, and to this end at least the distal portion may be of resilient form to be resiliently deformed from a first, relatively open, configuration to a second, relatively closed, configuration.
The invention has particular application in the field of central venous catheterization.
