Invagination suture according to Ramdohr, further developed by Jobert

Philipp Friedrich Ramdohr (born September 14, 1694 in Wolfenbüttel , † February 10, 1755 in Braunschweig ) was the personal surgeon of the Dukes of Braunschweig-Lüneburg and the inventor of a surgical sewing technique.

origin

He became the eldest surviving son from the first marriage of Melchior Franz Ramdohr (born September 19, 1661; † February 18, 1717) and his wife Dorothea (Lutheran) who was married in 1690 as a princely Brunswick mill clerk ( on the new mill ) since at least 1694 , * around 1670) born in Wolfenbüttel . His godparents were the Chancellor Philipp Ludwig Probst von Wendhausen , the privy councilor Friedrich Achaz Freiherr von der Schulenburg (1647–1701) and the ducal maid of honor Sophia Henrietta von Lente, wife of the Oberhofschenk Anton Albrecht Freiherr von Imhoff (* December 17, 1653; † 1715 in Dresden), all of them senior officials in the Braunschweig-Lüneburg state. Philipp Friedrich Ramdohr had the younger brothers Christian Heinrich (* September 22, 1701 in Wolfenbüttel; † 1730) and Anton Wilhelm Ramdohr (* October 13, 1707, at the baptism Duke Anton Ulrich and Hereditary Prince August Wilhelm were the godparents; † 1757, Berg -Chirurgus in Zellerfeld ) and the half-brother Dietrich Johann Ramdohr (born September 22, 1716; godparents were the commissioners Conerding and Matthei as well as a Fraulein Eberhard). Four other siblings died in early childhood.

Live and act

Ramdohr studied medicine and was body surgeon for the Duke of Braunschweig-Lüneburg from around 1722 . In 1727 he became known in the field of intestinal surgery through an intussusception operation carried out together with D. Kuntzius in Wolfenbüttel on an almost doomed woman from the people who suffered from a pinched hernia in the groin area, which after advanced inflammation developed into an abscess broke open, exposing about two feet of necrotic intestinal tissue. Ramdohr's method saved the woman's life and was an important medical novelty at the time. Although he did not publish this operation himself, the method was presented in a disputation by Johannes Fridericus Moebius, which he held on December 19, 1730 before Lorenz Heister in Helmstedt defended, who in turn described this method in 1739 and 1750. From then on, it was also referred to as the Ramdohr suture and was considered the best technique for sewing larger transverse wounds and circular incisions for over a century. This procedure inspired both Jobert de Lamballe (1824) and Lembert (1826) to conduct animal experiments on sutures on the intestine. Later modifications of this suture technique, for example by Peyronie in 1732, also took into account the invagination principle. Overall, Ramdohr's method thus led to advances in military medical services and intestinal surgery

Ramdohr also worked as a senior hospital surgeon from 1748 , took part in the campaign to Brabant and around 1751, in addition to his function as body surgeon under Duke Karl, also worked as a demonstrator for lectures in surgery at the Collegium Anatomico-Chirurgicum in Braunschweig. He also gave lessons for midwives in his private home for a long time and also performed operations on newborns (in 1751, for example, he repaired a harelip ). At Ramdohr's funeral on February 14, 1755, a mourning poem was published by his son-in-law, the lawyer Ernst Gottlieb Schmidt.
