Problems solved by technology

The problem with the external cervical approach is that 1. The incision is long and located in the neck, which affects the appearance of the patient
2. Due to the deep position of the styloid process, the shadowless lamp in the operating room cannot achieve effective lighting conditions at present, and the lighting direction and body position need to be changed repeatedly. 3. The separation of the neck to reach the styloid process needs to pass through important tissues such as the parotid gland, internal carotid artery, and facial nerve. Unfamiliar with the anatomical structure of the neck, it is easy to damage important tissues during the process of searching for the styloid process, resulting in serious complications 4. At present, there is no special instrument that can quickly and effectively peel off the attached muscle tissue on the styloid process Sometimes it is easy to stab the surrounding blood vessels and nerves, causing serious complications. 6. The existing surgical methods have high requirements for the surgeon, and require multiple people to cooperate in the operation

Embodiment 1

[0031] Example 1 as Figure 1-3 , 5, including a sleeve 1 and a percutaneous punching device that cooperates with the sleeve 1 to punch holes, and a crushing device for crushing the styloid process.

[0032] Both ends of the casing 1 are open, and a slope is provided at the front end; the slope is relatively gentle, and the angle between the slope and the axis is between 80° and 85°. The sleeve 1 is fixedly provided with an internally threaded sleeve 2 coaxial therewith, and the internally threaded sleeve 2 can also be connected to the sleeve 1 through an external thread, which is more convenient for replacement.

[0033] The percutaneous punching device includes a sharp piercing head 4, and a threaded post 5 is arranged behind the piercing head 4, and the threaded post 5 is mated and connected with the inner threaded sleeve 2 in the casing 1.

[0034] The crushing device includes an external threaded sleeve 6 with openings at both ends that cooperates with the internal threa...

Embodiment 2

[0042] Example 2 as Figure 4 Shown, compared with embodiment 1, the mode of its pulverization is slightly different. The crushing device includes an external thread sleeve 6 with openings at both ends that cooperates with the internal thread sleeve 2 of the casing 1; the external thread sleeve 6 is provided with a number of discontinuous crushing teeth 11 arranged in a spiral, and the several crushing teeth Teeth 11 are surrounded by a tapered sleeve shape with a large bottom and a small top.

[0043] In this embodiment, the purpose of cutting off the styloid process 12 can also be achieved by destroying the styloid process 12 through the crushing teeth 11 arranged in a helical shape and staggeredly arranged.

[0044] In this application, the styloid process of the temporal bone is truncated by crushing the styloid process instead of the existing breaking method. The incision is small and the truncated length is more controllable. For the protection of the sleeve, the surro...

Abstract

The invention discloses a percutaneous perforating styloid process shortening system. The system comprises a casing pipe, a percutaneous perforating device matched with the casing pipe for perforatingand a crushing device for crushing the styloid processes. Compared with a traditional operation mode of external neck incision and breaking of the outer cervical paths, the system has the advantagesthat under an adopted perforating and crushing pattern, the operation wound is small, the recovery speed is high, the operation time is short, the operation difficulty of operators is lowered, a greatillumination condition is provided for a wound area, the damage of surrounding tissue is small, and there are few complications.

Description

technical field [0001] The present invention relates to a system for truncation of the styloid process of the temporal bone. 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 ...
