The invention discloses a soft tissue expander, which comprises two forceps bodies which are movably connected, wherein the forceps bodies comprise handle parts and straight parts; soft tissue expansion sheets are fixed to the ends of the straight parts of the forceps bodies; an adjusting rod is arranged between the handle parts of the forceps bodies; and the adjusting rod comprises a first spiral sleeve which is fixed to the handle part of the first forceps body and a second spiral sleeve which is fixed to the handle part of the second forceps body in a mode of being opposite to the first spiral sleeve, and the adjusting rod comprises screw rods which are mutually connected and are embedded into the first spiral sleeve and the second spiral sleeve. According to the device (the soft tissue expander), expansion degrees of the soft tissue expansion sheets can be precisely regulated and controlled, so that tearing degree of a wound can be precisely controlled; and meanwhile, with the application of the device, probability of esophageal fistula in an anterior cervical surgery course can be also reduced.
Description
Technical field [0001] The invention belongs to the technical field of medical equipment, and specifically relates to a soft tissue expander. Background technique [0002] Cervical myelopathy (compression of the cervical spinal cord after a herniated disc) is a common disease that has plagued patients for a long time. Most of the current treatment methods use open surgery, that is, anterior cervical discectomy, decompression and fusion, which has large surgical trauma, long recovery time for patients, and high treatment costs. With the development and progress of minimally invasive technology, spine endoscopic anterior approach surgery for cervical spondylotic myelopathy has emerged. Its advantages are: less surgical trauma, surgery under local anesthesia, faster recovery of patients after surgery, and lower treatment costs. This operation requires an incision of about 4mm in the skin of the front of the neck, the puncture is positioned to the target area, and then the soft tiss...
