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

[0035] Example 1 as Figure 1-8 As shown, it includes a cannula 1 and a percutaneous punching device that cooperates with the cannula 1 to punch holes, a cutting device for shortening the styloid process, and a tissue stripping device for stripping the attached tissue on the styloid process.

[0036] 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. The cannula 1 not only serves as a channel for other devices to enter and leave the human body, but also serves as a barrier to prevent damage to blood vessels and nerves outside the styloid process 10 . In addition, during the process of inserting the styloid process 10 , t...

Embodiment 2

[0042] Example 2 as Figure 4 As shown, there are four cutting blades 5 evenly distributed along the circumference, and the cutting blades 5 have sharp working parts. The cutting edge 5 includes a blade 21, and the tail end of the blade 21 is fixedly connected with a connecting rod 23; it also includes a mounting seat 22 fixed on the inner ring surface of the rotating sleeve 4, and the front end of the mounting seat 22 has a small hole; the connecting rod 23 extends into the mounting seat 22 through a small hole, and the part of the connecting rod 23 located in the mounting seat is covered with a preload spring 24; the connecting rod 23 and the inner wall of the mounting seat 22 are provided with a spring seat. The cutting edge 5 of the above structure cuts more thoroughly because the blade 21 can extend to the center of the circle of the rotating sleeve 4 .

[0043] The cutting blades in Embodiment 1 and Embodiment 2 can be used alone or in conjunction with each other. That...

Abstract

The invention discloses percutaneous perforating equipment for truncating a temporal bone styloid process. The equipment comprises a sleeve, a percutaneous perforating device matching the sleeve for perforating, and a cutting device for truncating the styloid processes. Compared with a traditional operation mode which combines external cervical incision with breaking, the system of the invention adopts a perforating and cutting mode, the operation wound is small, recovery is fast, the operation time is short, the operation difficulty of an operator is reduced, good wound area illumination is provided, damage to surrounding tissues is small, and complications are few.

Description

technical field [0001] The invention relates to a device for shortening 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 radiate to ...
