Abstract
A surgical wound retractor comprises a retracting member for insertion into a wound opening and a proximal member for location externally of a wound opening A clamp is used to clamp the retracting member to the proximal member.
Claims51
A surgical wound retractor comprising:—
- a retracting member for insertion into a wound opening;
- a proximal member for location externally of a wound opening;
- and
- a clamp for clamping the retracting member to the proximal member.
A retractor as claimed in any preceding claim wherein the proximal member comprises an annular ring means.
A retractor as claimed in any preceding claim wherein a surface of the proximal member which engages with the retracting member is of a material with a low coefficient of friction.
A retractor as claimed in any preceding claim wherein the sleeve is generally cylindrical.
A retractor as claimed in any preceding claim wherein the retracting member comprises a proximal reinforcing means.
A retractor as claimed in any preceding claim wherein the retractor comprises a distal member coupled to a distal end of the retracting member for insertion into a wound opening.
A retractor as claimed in any preceding claim wherein the retractor comprises a platform for attachment of another device to the retractor.
A surgical wound retractor comprising:—
- a retracting member movable from an insertion configuration to a retracting configuration to retract laterally a wound opening;
- and
- means for clamping the retracting member in the retracting configuration to maintain a wound opening retracted.
A surgical wound retractor comprising:—
- a distal anchoring member for insertion into a wound opening;
- a connecting means having an inner wound engaging portion and an outer portion, the wound engaging portion being mounted to the distal anchoring member, the connecting means having an insertion configuration in which the inner wound engaging portion has a reduced radial dimension and a retracting configuration;
- an external guide means for the outer portion of the connecting means;
- the external guide means being movable relative to the connecting means to shorten the axial extent of the connecting means and thereby bias the wound engaging portion of the connecting means into the retracting configuration to retract the wound opening laterally;
- and
- a clamp for clamping the connecting means to the external guide means to maintain retraction of the opening.
A surgical wound retractor substantially as hereinbefore described with reference to the accompanying drawings.
A method of retracting a wound opening, the method comprising the steps of:—
- inserting a retracting member into a wound opening;
- locating a proximal member externally of the wound opening;
- moving at least part of the retracting member laterally to retract the wound opening;
- and
- clamping the retracting member to the proximal member to maintain the wound opening retracted.
A method for retracting a wound opening using a surgical wound retractor comprising a distal anchoring member, a connecting means having a wound engaging portion mounted to the distal anchoring member and an outer portion, an external guide means for the outer portion of the connecting means and a clamp;
- the method comprising the steps of:—
- positioning the distal anchoring member to be retained inside a wound opening with the connecting means extending outwardly therefrom through the opening;
- moving the external guide means relative to the outer portion of the connecting means to shorten the axial extent of the connecting means and thereby bias the wound engaging portion into a retracting configuration to retract the wound opening;
- and
- clamping the connecting means to the external anchoring means to maintain retraction of the wound opening.
