Improved device for percutaneous tracheotomy

Abstract

The invention relates to an improved device for percutaneous tracheotomy. The device comprises an outer sleeve, a puncture needle and a guide wire. The outer sleeve is made of stainless steel materials, the whole outer sleeve is in a linear shape, outer sleeve scale marks are arranged on the outer wall of the outer sleeve, the head end of the outer sleeve is designed to be of a spoon-shaped inclined face, an outer sleeve connecting base is arranged at the tail end of the outer sleeve, and a first identification component is arranged on the outer sleeve connecting base; the position of the first identification part on the outer sleeve connecting base is used for indicating the direction of a guide wire guided by the spoon-shaped inclined surface at the head end of the outer sleeve; a puncture needle connecting base is arranged at the tail end of the puncture needle, a second identification component is arranged on the outer wall of the puncture needle connecting base, and the second identification component is matched with the first identification component; and guide wire scale marks are arranged on the outer wall of the guide wire. The device can realize accurate, safe and convenient implementation of percutaneous tracheotomy.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an improved device for percutaneous tracheotomy. Background technique [0002] Tracheotomy is a common clinical operation, and it is suitable for critically ill patients who require long-term mechanical ventilation and maintain airway patency due to various etiologies. Compared with traditional tracheostomy, percutaneous tracheostomy has the advantages of less surgical trauma, safe and simple operation, and fewer related complications. At present, percutaneous tracheostomy is commonly used in clinical practice, and the instrument used is percutaneous tracheostomy. The incision set includes a blade, a puncture needle, an outer cannula, a skin expander, a guide wire, a guide forceps, and a disposable tracheal cannula. The operation process is as follows: (1) The blade cuts the epidermis. (2) The puncture needle with a cannula is used to puncture the trachea (3rd-4th ca...

AI Technical Summary

Problems solved by technology

[0003] Disadvantages of the current percutaneous tracheotomy set: (1) The puncture needle outer tube is made of plastic material, which is not hard enough. After the puncture needle is withdrawn, if the patient coughs, it will cause the trachea and skin to move, and the tube lumen will be compressed or Bending, making subsequent guidewire placement difficult

In addition, the head end of the cannula lacks a direction guiding function, and the guide wire inserted into the trachea may mistakenly enter the head end, resulting in failure of tracheotomy

There is no scale marking on the outer cannula, so the puncture depth cannot be accurately controlled

(2) The puncture needle has a sharp bevel incision, which is easy to damage the neck blood vessels and nerves around the puncture tract

(3) The guide wire also lacks scale marks, which makes it difficult to accurately control the depth of the guide wire

[0006] However, the above technical solutions have not completely solved all the defects of the aforementioned percutaneous tracheotomy set. At present, there is an urgent need for a device that can keep the puncture cavity unobstructed, strictly control the correct direction of the guide wire, control the puncture depth, reduce the damage during the puncture and The guide wire is inserted into the depth-controllable percutaneous tracheostomy device, and there are no relevant reports so far
