Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1 and 2 together, the percutaneous bone nail surrounding skin fixing device comprises two fixing parts a, wherein the fixing parts a comprise a supporting part 1 and a fixing part 2 which are connected together, the supporting part 1 of the two fixing parts a is supported on the bone nail, and the fixing part 2 of the two fixing parts a is attached to the skin around the bone nail for fixing the skin.

As shown in fig. 1 and fig. 2, the fixing portion 2 in this embodiment is provided with a hollow medicine application observation area 21, and the medicine application observation area 21 is located on the periphery of the supporting portion 1. The medicine application, nursing and observation are carried out on the skin around the bone nail through the medicine application observation area 21, so that the infection rate of the skin around the bone nail is reduced, and the treatment effect is improved.

As shown in fig. 1 to 3, in the present embodiment, two fixing parts a are preferably arranged in a butt joint manner, and a first locking structure 3 and a second locking structure 4 are arranged on each of the two fixing parts a, wherein the first locking structure 3 of one fixing part a is detachably connected with the second locking structure 4 of the other fixing part a. In this embodiment, it is preferable that the first locking structure 3 is a locking protrusion, the second locking structure 4 is a locking hole, and the locking protrusion and the locking hole are both disposed on the abutting surface of the fixing component a. In practical applications, the first locking structure 3 and the second locking structure 4 may also adopt other locking structures, such as locking of locking members, and the like, and this embodiment is not limited thereto. The two fixing parts a are connected together through the first locking structure 3 and the second locking structure 4, so that the combination tightness of the two fixing parts a and the bone nail is improved, the two fixing parts a are fixed more firmly, and the skin around the bone nail is further reduced to be pulled.

As shown in fig. 1 to 3, preferably, two support portions 1 are arranged in a butt joint manner in this embodiment, the two support portions 1 are semicircular and are adapted to bone nails, an avoiding space is provided between one side of each of the two support portions 1, which is close to the skin, and the skin is prevented from being damaged by the two support portions 1, and the first locking structure 3 and the second locking structure 4 are arranged on a butt joint surface of the support portions 1.

As shown in fig. 1 and fig. 2, the upper surface of the fixing portion 2 in this embodiment is provided with an adhesive tape limiting post 23. In the embodiment, the two fixing parts a are fixed by the non-woven wide adhesive tape, and the adhesive position of the adhesive tape is limited by the adhesive tape limiting column 23, so that the two fixing parts a are fixed more firmly.

As shown in fig. 1 and 2, the tape limiting column 23 of the present embodiment is disposed at one end where the two fixing parts a are butted. The adhesive tape limiting column 23 is arranged at the position, the butt joint of the butt joint surfaces of the two fixing parts a is firmer by adhering the adhesive tape, and the two fixing parts a are prevented from moving relatively.
