Abstract
The invention concerns a clamp, especially a surgical clamp, with a left clamp half to receive a left half of a breastbone during a surgical procedure, a right clamp half to receive a right half of the breastbone, as well as a first toothed rod and a detent mechanism engaging in the first toothed rod to secure the left clamp half at a distance from the right clamp half, wherein the detent mechanism engaging in the first toothed rod has a detent region extending at least from the left clamp half to the right clamp half.
Claims24
A surgical clamp, comprising:
- a left clamp half,
- a right clamp half,
- a first toothed rod affixed on one end to the right clamp half,
- a detent mechanism within the left clamp half engageable with the first toothed rod to secure the left clamp half at a distance from the right clamp half;
- and
- characterized in that the detent mechanism engageable with the first toothed rod has a detent region extending at least from the left clamp half to the right clamp half,
- wherein the detent mechanism engaging in the first toothed rod is a second toothed rod:
- the left clamp half and the right clamp half are each provided with a respective housing;
- the housings each having a continuous opening bounding a through passage into which at least one of the toothed rods can be introduced during a use thereof;
- the width of the openings of each of the housings being adapted to the width of the respective toothed rods:
- at least one plate having lugs is provided on at least one of the toothed rods or on the clamp halves. whereby the at least one plate enables affixing the clamp to an external bone member during the use;
- a toothing of each respective toothed rod is respectively configured such that a plurality of flanks belonging to respective teeth of each said toothing run in the same direction relative to said toothing from the perspective of a base of the tooth to a tip of the tooth.
