Description

A medical clamp

technical field

The invention relates to the field of medical instruments, in particular to a fixing clip for an external fixator.

Background technique

The treatment of external fixation after fracture surgery is one of the commonly used methods in clinical practice. It has been clinically used for decades. In recent years, the ilizarov technique has become more and more widely used in the treatment of limb bone defects, bone infection, limb orthopedics and limb ischemic lesions. The stent is worn for a long time, usually 1-3 years, and local care and dressing change after wearing become one of the difficulties in daily life. In order to prevent local seepage and pollutants from entering the body along the fixed steel needle, the needle port of the fixed screw or steel needle needs to be protected by dressing. The dressing is easy to loosen and fall off after dressing the needle port. At present, bandages are commonly used to fix it, which is inconvenient for partial dressing.

Contents of the invention

The invention provides a kind of fixing clip applied in the treatment technology of external fixation frame, especially in the ilizarov technology, which is used for bandaging and fixing the needle mouth of steel needle. The present invention adopts the following technical scheme: a kind of fixing clip for external fixation frame, comprising Main body and force applying device.

The main body includes two clamp bodies with axisymmetric structure. The clamp bodies are clamping mouth, clamping hole and connecting end in sequence from front to back. The two clamping bodies are movably connected through the connecting ends. The clip body is provided with an axisymmetric concave hole between the connecting end and the clamping mouth, and the two concave holes form a clamping hole, and the clamping hole is used to bite the external fixator steel needle. The medical dressing is arranged on the lower end surface of the clip body. A locking device is arranged on the clamping mouth, and the locking device is used to provide the occlusal force of the clamping hole. An operating part is provided on the clip body for driving the two clip bodies to rotate in opposite directions around the connecting end.

Further, the shape of the clamping hole is one of circle, ellipse, triangle, polygon or rhombus.

Further, there are teeth on the clamping hole, and the shape of the teeth is one of triangular teeth, round teeth or saw teeth.

Further, the width or diameter of the clamping hole is less than or equal to 6mm.

Preferably, the width of the clamping hole is 2mm, 3mm, 4mm, 5mm or 6mm.

Further, the operating part is a clamping post or a clamping hole, which is arranged on the upper end surface of the clamping body.

Further, the main body is provided with a clamping column or a clamping hole, so that the clamping operation can be conveniently performed in the narrow operating space of the external fixator.

Further, the two clip bodies can be connected integrally or detachably at the connection end.

Further, the force applying device is a return spring, a magnet or a locking structure, and any structure in the prior art for realizing fixed locking may also be used.

As a further improvement of the present invention, there are antibiotics or antibacterial drugs on the medical dressing.

As a further improvement of the present invention, the bottom surface of the clip body, that is, the surface in indirect contact with the human body through the medical dressing is a curved surface, and the curved surface fits the curved surface of the human body.

The working principle of the present invention is: when performing ilizarov technique treatment, after the position of the steel needle entrance of the external fixation frame is sterilized with alcohol, use tweezers to separate the clamping mouth by operating the clamping column or the clamping hole respectively, and place the steel needle Insert the clamping hole into the clamping hole to make the clamping hole fit the steel needle, and then close the clamping mouth. At this time, the clamping hole bites the steel needle, and then push the fixing clip along the direction of the steel needle until it fits the skin.

The beneficial effects of the present invention are:

1. The fixing clip provided by the present invention can effectively prevent local seepage and pollutants from entering the body along the fixed steel needle, and prevent the loosening and falling off of the medical dressing;

2. The integration of dressing, liquid medicine and fixing clip not only reduces the operation steps, but also increases the continuity of treatment and the shielding effect;

3. The fixing clip can be easily replaced, which can prevent the material from deteriorating and rotting caused by the fixing clip being in contact with body fluid for a long time.

Detailed ways

It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

As shown in FIGS. 1-2 , a medical fixing clip provided by an embodiment of the present invention includes a main body 1 , a locking device 3 and a medical dressing 4 .

The main body includes a first clamping body 7 and a second clamping body 8 with two axially symmetrical structures, one end of the first clamping body 7 and the second clamping body 8 are integrally connected by a connecting end 9, the first clamping body 7 and the second clamping body The other end of the clip body 8 constitutes a clamping opening 10, on which a force applying device 3 is arranged, and the force applying device 3 is two mutually attracting magnets. The lower end surfaces of the first clip body 7 and the second clip body 8 are connected to the medical dressing 4 by glue. Both the upper end surfaces of the first clamping body 7 and the second clamping body 8 are provided with cylindrical clamping columns 2 .
