Percutaneous punching and belemnoid truncation device

Abstract

The invention discloses a percutaneous punching and belemnoid truncation device. The percutaneous punching and belemnoid truncation device comprises a skin traction device, a belemnoid truncator and asleeve for supporting the skin traction device and guiding the belemnoid truncator, wherein a guide rod is arranged in the sleeve in the axial direction of the sleeve. The percutaneous punching and belemnoid truncation device further comprises a slider in sliding fit with the guide rod. A support is fixed to the slider and provided with a rotating shaft. A driving wheel fixedly sleeves the rotating shaft. The percutaneous punching and belemnoid truncation device further comprises a plurality of tensioning wheels fixed to the support. A steel wire rope for truncating belemnoid is wound on thedriving wheel and the tensioning wheels. A pretightening spring for driving the slider to move downwards is arranged at the position, above the slider, of the guide rod. The principle is that the steel wire rope is driven by the driving wheel to move and the belemnoid is truncated by the rapidly-moving steel wire rope. The pretightening spring has downward acting force so that the steel wire ropecan closely fit the belemnoid all the time without manual intervention.

Description

technical field [0001] The present invention relates to a device for styloid process shortening. Background technique [0002] Temporal styloid process refers to the thin and long bony protrusion that protrudes forward and downward under the temporal bone, usually ranging from a few millimeters to 2.5cm, and is located below the ear. Styloid syndrome, also known as overlong styloid process, Eagle syndrome, styloid neuralgia. Styloid process syndrome is a foreign body sensation in the pharynx, sore throat or reflex otalgia, pain in the head and neck and salivary glands caused by excessively long styloid process (more than 2.5cm) or stimulation of adjacent blood vessels and nerves due to its abnormal position and shape. A general term for symptoms. Common in adults. The onset is slow, and the medical history varies in length. There is often pain in the tonsil area and the base of the tongue, which is often unilateral, usually not severe, and can radiate to the ear or neck, ...

AI Technical Summary

Problems solved by technology

However, in actual use, the inventor found that it is inconvenient to use a circular saw to shorten the styloid process, and it is easy to deviate during the manual lifting process, and the shortening efficiency is not high

At the same time, it is necessary to put the circular saw on the styloid process before shortening, which is difficult to operate
