Problems solved by technology

Invasive skin closure external fixation brackets are mostly made of plastic materials, which are not easy to sterilize, and the bone needles are very thin, which can easily cause insufficient pulling force to cover the skin and soft tissue or excessive pulling force, thereby cutting the skin and soft tissue prone to secondary injury

Embodiment Construction

[0015] The present invention will be further described below in conjunction with accompanying drawing.

[0016] see figure 1 and figure 2 , The skin closure external fixation bracket of the present invention includes a pair of sliding side blocks 1, a threaded flat rod 2, two springs 3, a pair of sheet nuts 4 and a plurality of Z-shaped bone needles 5.

[0017] The two sliding side blocks 1 are sleeved on both sides of the threaded flat rod 2 respectively, that is, the sliding side block 1 has a flat through hole 11 through which the threaded flat rod 2 passes. Two piece nuts 4 are respectively screwed on the two ends of the threaded flat rod 2 to correspond to the two sliding side blocks 1 one by one. Each corresponding sliding side block 1 and the piece nut 4 are connected by a spring 3 that is also sleeved on the threaded flat rod 2 to play a certain buffering effect.

[0018] The sliding side block 1 is provided with a flat hole 12 for inserting the tail end of the Z-s...

Abstract

The invention discloses a skin occlusion outer fixing bracket. The skin occlusion outer fixing bracket comprises a threaded flat rod, a pair of sliding side blocks, a pair of sheet nuts, a plurality of Z-shaped bone spicules and two springs, wherein the pair of sliding side blocks is arranged on both sides of the threaded flat rod in a sleeving way; the pair of sheet nuts is screwed at the two ends of the threaded flat rod and corresponds to the sliding side blocks one by one; the two springs are arranged on the threaded flat rod in a sleeving way and are connected with corresponding sliding side blocks and sheet nuts respectively; the heads of the two Z-shaped bone spicules are relatively fixed on opposite sides of the two sliding side blocks respectively. During use of the skin occlusion outer fixing bracket, skin or soft tissues are prevented from being cut, so that secondary harm is avoided.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a skin closure external fixation bracket. Background technique [0002] The skin closure external fixator is mainly used clinically for traction repair of skin, muscle and tendon soft tissue. It is used to stretch the soft tissue with large defect or partial skin for covering direction traction, and finally achieve the effect of skin coverage. [0003] At present, clinically commonly used skin closure external fixation brackets can be divided into two types: invasive and non-invasive. Invasive skin closure external fixation brackets are mostly made of plastic materials, which are not easy to sterilize, and the bone needles are very thin, which can easily cause insufficient pulling force to cover the skin and soft tissue or excessive pulling force, thereby cutting the skin and soft tissue It is easy to cause secondary injury. Contents of the invention [0004] The purpose of the...
