Abstract

The invention relates to a tracheostoma spacer with a tubular support framework. The support framework can be expand from an initial state to a supporting state of increased diameter and has a fixing element at the ends. The tracheostoma spacer is intended for use as a spacer in a tracheostoma (an opening in the trachea). The invention further relates to a device for inserting a tracheostoma spacer into a tracheostoma with a cutting instrument in the form of a trocar, the tracheostoma spacer being able to be positioned on the shaft of said trocar. A cover sleeve is also provided which can be moved on the shaft over a tracheostoma spacer positioned there.

Claims

1. Tracheostoma spacer with a tubular support framework, wherein the support framework is able to expand from an initial state to a supporting state of increased diameter and has a fixing element at the end.

11. Tracheostoma spacer according to claim 1, wherein the support framework has tubular guide elements to guide the tracheotomy device or a catheter to be inserted through the tracheostoma spacer.

38. Tracheotomy device for inserting a tracheostoma spacer according to claim 1 into a tracheostoma, wherein the tracheotomy device comprises a cutting instrument on whose shaft the tracheostoma spacer can be placed, and a cover sleeve which is movable on the shaft over a tracheostoma spacer that has been placed there.

39. Tracheotomy device according to claim 38, wherein the cutting instrument has a conical tip.

40. Tracheotomy device according to claim 38, wherein the cutting instrument has a channel for a guide wire.

41. Tracheotomy device according to claims 38, wherein the cutting instrument comprises a needle.

42. Tracheotomy device according to claim 38, wherein the cutting instrument comprises a knife, a scalpel, or a trocar.

43. Tracheotomy device according to claim 38, wherein a cuff is arranged on the cover sleeve.

44. Tracheotomy device according to claim 38, wherein the shaft has a magazine section.

45. Tracheotomy device according to claim 38, wherein the shaft has a guide section.

46. Tracheotomy device according to claim 38, wherein the shaft and the cover sleeve are curved.

47. Tracheotomy device according to claim 38, wherein an outer shape is adapted in cross section to be capable of adapting to an opening of the trachea.

48. Tracheotomy device according to claim 38, wherein a grip surface is provided.

49. Tracheotomy device according to claims 38, wherein a safety element is provided to protect from over-inserting the tracheotomy device into the trachea.

50. Tracheotomy device according to claim 49, wherein the safety element is a housing.

51. Tracheotomy device according to claim 49, wherein the safety element is an abutment.

52. Tracheotomy device according to claim 49, wherein the safety element is an arc shape formed along an axial length of the tracheostoma spacer to facilitate a curved entrance through the skin and into the trachea.
