Protection system for blood vessels and nerves in post-traumatic local exposed bone regions

Abstract

The invention discloses a protection system for blood vessels and nerves in post-traumatic local exposed bone regions. The protection system comprises a protecting cover and a shaping device, whereinthe protecting cover is used for preventing the blood vessels and the nerves from being extruded by a pressure source, and an accommodating space for accommodating the blood vessels and the nerves isformed in the protecting cover; and the shaping device is used for shaping the protecting cover so as to enable the extension direction of the accommodating space to be accordant with the trend of thenerves. The protection system comprises the protecting cover, the protecting cover is used for covering the post-traumatic exposed blood vessels and nerves into the accommodating space, and an isolation region is formed on the peripheral regions of the post-traumatic exposed blood vessels and nerves, so that the situation that the blood vessels and the nerves are pressed by materials such as negative pressure cotton in a subsequent closed negative pressure drainage is avoided. Meanwhile, the protection system further comprises the shaping device for shaping the protecting cover, so that the protecting cover is adapted to the trends of the blood vessels and the nerves, and the protecting cover is capable of effectively protecting the blood vessels and the nerves in the post-traumatic localexposed bone regions.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a blood vessel and nerve protection system in a local bone exposed area after trauma. Background technique [0002] With the development of society and the expansion of transportation and industrial production, personal accidents often occur, accompanied by the occurrence of limb trauma. When large limb trauma occurs, limb interruption is often accompanied by large muscle and skin defects or necrosis, and local bone exposure. It should be noted that although the muscles and skin of the limbs have large areas of damage or necrosis after limb injury, occasionally there will be a small number of complete blood vessels and nerves. At this time, the protection of these still functioning blood vessels and nerves It plays a very important role in the recovery of limbs in the later stage; especially when the injury occurs in the middle of the limb and the end of the limb is st...

AI Technical Summary

Problems solved by technology

[0004] The closed negative pressure drainage technique is currently a better clinical treatment for limb defects. However, this method is not friendly to the surviving blood vessels and nerves. In the local bone exposure area after trauma, the bone will be completely exposed or only a small amount of muscle remains. The exposed blood vessels and nerves lack both shielding and soft support. In this way, the negative pressure sponge will directly compress the blood vessels and / or nerves, causing huge damage to the exposed blood vessels and / or nerves, and even causing necrosis, which will further aggravate the later stage Difficulty of limb recovery

[0005] In the current surgery for large-area limb tissue defects, no protective measures have been taken for blood vessels and / or nerves in the local bone exposure area after trauma
