Problems solved by technology

But it also has its disadvantages. The splint only fixes the middle segment and the distal segment of the affected finger, while the extensor tendon of the finger is connected to the entire finger. The movement of the finger near the interphalangeal joint will undoubtedly affect the recovery of the affected finger, and the finger naturally moves toward the finger. The center of the palm is bent, and it is only fixed at the middle and distal segments, which will easily cause the splint to loosen and the fixation effect is poor

Abstract

The invention relates to the field of treatment of mallet fingers, and in particularly relates to a postoperative fixing device for a mallet finger. The device comprises a fixing plate and a fixing belt, wherein the fixing plate is a sheet body provided with a groove on the lower surface, the fixing plate is spoon-shaped from side-looking, and the fixing plate comprises a carpometacarpal joint fixing sheet, a finger hill section fixing section, a finger median segment fixing section and a distal finger fixing section from the front end to the tail end. The distal finger fixing section extends upward from the tail end of the finger median segment fixing section, and the finger hill section fixing section and the finger median segment fixing section as well as the finger median segment fixing section and the distal finger fixing section are in circular arc transition. According to the treatment demand, angles among the three sections are designed to facilitate postoperative recovery. The fixing belt is designed in sections and the carpometacarpal joint fixing sheet is additionally arranged, so that the fixing effect is good. The comfort level of the patient is improved due to arc shapes at transition of three sections, the groove and the cushion layer.

Description

technical field [0001] The invention relates to the field of mallet finger treatment, in particular to a hammer finger postoperative fixation device. Background technique [0002] Hammer finger is a rupture of the finger extensor tendon at its insertion at the base of the distal phalanx, resulting in a flexion deformity of the distal interphalangeal joint. At present, surgery is mostly used for the treatment of mallet fingers, but postoperative external fixation with plaster bracket is the main method, that is, external fixation with plaster and tape for 6 weeks, but this fixation method has poor air permeability, and it is difficult to adjust the tightness of the fixation once it is fixed. degree, and it is easy to cause skin allergies and even local ulceration. Now it is gradually fixed with a fixed plate. The existing fixed plates include stack splint, Mikes splint, and Tsuxia splint. These splints are all fixed on the inner side of the finger (palm side). After being f...
