Description
Technical Field
The invention relates to the technical field of medical appliances, in particular to a positioning auxiliary clamp and a reduction set for fracture surgery.
Background
In fracture reduction surgery, an anatomic plate is generally used to fix the distal end and the proximal end of the fractured bone, respectively, so that the bone is accurately reduced and fixed.
The specific operation flow of the operation is that the head end of the anatomical plate is fixed at the distal end of the bone by the screw, and then the tail end of the anatomical plate is fixed at the proximal end of the bone by the screw, so that the bone is restored and fixed at the original position.
The tool for clinically performing fracture reduction operation is mainly a reduction forceps, but the reduction forceps can only clamp and fix the proximal end of a bone, and when an anatomic plate swings on the bone around the head end of the anatomic plate, the anatomic plate is difficult to detect by naked eyes. At this time, after the tail end of the anatomical plate is fixed to the proximal end of the bone, the distal and proximal ends of the bone are offset and cannot be restored to the original position before fracture.
Disclosure of Invention
The invention aims to provide a positioning auxiliary clamp and a reduction kit for fracture surgery, which are helpful for assisting in observing and keeping an anatomical plate from swinging and displacing when clamping and fixing the proximal end of a bone, and further ensuring that the distal end and the proximal end after fracture of the bone can be fixed and restored to the original positions.
The invention is realized in the following way:
The positioning auxiliary clamp comprises a first clamp arm, a second clamp arm, a positioning mechanism and a guiding mechanism, wherein the first clamp arm and the second clamp arm are mutually hinged, the first clamp arm and the second clamp arm are respectively connected with the positioning mechanism, the guiding mechanism is arranged on the positioning mechanism, and a drill bit can always point to the midpoint position between the first clamp arm and the second clamp arm through the guiding mechanism in the swinging process of the second clamp arm relative to the first clamp arm.
When the positioning auxiliary forceps are used, the head end of the anatomical plate is fixed at the distal end of the bone, and then the tail end of the anatomical plate is extended to a proper position on the proximal end of the bone. At this time, the proximal end of the bone is gripped by the first and second jawarms, and then the positioning mechanism is used to determine the position and angle of the guide mechanism so that the drill bit, after passing through the guide mechanism, is directed precisely at the midpoint between the first and second jawarms. That is, the position of the tail end of the anatomic plate on the proximal end of the bone can be accurately located, and even if the anatomic plate undergoes a slight displacement, correction can be clearly found and quickly repositioned.
The positioning mechanism comprises a first sling and a second sling, wherein two ends of the first sling are respectively hinged to the outer walls of the first clamp arm and the guide mechanism, two ends of the second sling are respectively hinged to the outer walls of the second clamp arm and the guide mechanism, and the length of the first sling is equal to that of the second sling.
