Abstract

A medical stapler and screw inserter device is disclosed herein wherein the medical instrument is formed in a non-linear or “C” or “V” shaped conformation. The non-linear shape allows the physician to accomplish a per vaginal anchor or screw insertion into a patient'"'"'s pubic bone, while locating the triggering hand outside of the vagina of the patient and employing a pulling force on the inserter/stapler, against the pubic bone of the patient. In addition, the weight of a patient'"'"'s body may be used to counterweight the recoil effect to minimize stapler recoil during ejection of a staple from the stapler into a patient. Bone anchor screws and a related bone screw driver and a method of inserting it into the pubic bone through the vagina are also described for per vaginal bladder neck suspension procedures.

Claims

1. A medical inserter device for installing a bone anchor with attached suture into a patient, comprising:

a handle, said handle being at a first end of said medical inserter device;

a body, said body being attached to said handle, said body and said handle together forming a non-linear shape,

an anchor housing located at a second end of said body, opposite to said first end, for holding a bone anchor during installation;

a retractable shield proximate said anchor housing;

a power source in communication with said anchor housing for providing power to install said bone anchor; and

,

a trigger in communication with said power source.

2. A medical inserter device as claimed in claim 1, wherein said body and said handle together form a C shape.

3. A medical inserter device as claimed in claim 1, wherein said body and said handle together form a V shape.

4. A medical inserter device as claimed in claim 1, wherein said inserter device is a medical stapler for forcibly ejecting and implanting a bone anchor into the bone of a patient.

5. A medical inserter device as claimed in claim 1, wherein said inserter device is a screw driving device for screwing a bone anchor into the bone of a patient.
