Abstract

A surgical retractor comprising a retractor body having a site portion and a handle portion, and an impactor body on the retractor body. The impactor body is positioned and configured for use in impacting the site portion in the surgical site. An impaction axis of the impaction body is preferably substantially aligned with an axis of the site portion of the impactor body. The impactor body is preferably attached to the retractor body at a junction between the site portion and the handle portion of the retractor body. In one embodiment, the impactor portion is configured to selectively mate with an impactor extension member to thereby optionally receive direct impaction on the impactor portion or indirect impaction through the impactor extension member.

Claims

1. A surgical retractor for use in a surgical site in hip surgery comprising:

a retractor body having a site portion and a handle portion, and

a separate impactor extension member, said separate impactor extension member comprising a unibody solid impaction structure having a female leading end, an impactor surface on a trailing end, and a lengthwise straight portion extending between said leading end and said trailing end, said female leading end configured to receive an impaction surface of said retractor body,

an impactor body on said retractor body, said impactor body positioned and configured for use in impacting said site portion in the surgical site,

said impactor body including an impactor portion having an impaction surface and a support portion, said impactor body fixedly attached to said retractor body via said support portion,

said impactor body attached to said retractor body at a junction between said site portion and said handle portion of said retractor body,

said impactor portion having an oval shape configured to selectively mate with said impactor extension member to thereby optionally receive direct impaction on said impaction surface of said impactor portion or indirect impaction through said impactor extension member, as well as to enable manipulation of said site portion via said impactor extension member, a lengthwise axis of said oval shape substantially parallel to a widthwise dimension of said site portion, and

an impaction axis of said impaction body substantially aligned with an axis of said site portion of said impactor body, and

said impactor portion and said impactor extension member configured to mate such that an impaction axis of said impactor body and an impaction axis of said extension member are substantially axially aligned.

2. The surgical retractor of claim 1, wherein said junction is bent.

3. A surgical retractor of claim 1, wherein said surgical retractor is sized and configured for use in minimally invasive hip procedures.

4. A surgical retractor of claim 3, wherein said handle portion is longer than said site portion in order to accommodate hip surgery procedures.

5. A surgical retractor of claim 4, wherein said handle portion is angled at about 110 degrees relative to said site portion in order to accommodate hip surgery procedures.

6. A surgical retractor of claim 1, wherein a cross-sectional width of said impactor portion of said impactor body is larger than a cross-sectional width of said support portion of said impactor body.

7. A surgical retractor of claim 1, wherein said impactor portion is configured to mate with said impactor extension member in a non-rotating relationship, such that about 5 or 6 degrees of freedom of motion are controlled at a junction of said impactor portion and said impactor extension member.
