Embodiment Construction

[0025] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in various ways defined and covered below.

[0026] refer to figure 1 , the preferred embodiment of the present invention provides a kind of nerve guidance device, comprises: the absorption head 10 that is used to coat the stump of the nerve of the nerve to be pulled, the absorption head 10 is communicated with guide strip 20, and guide strip 20 uses Under the action of external force, the suction head 10 is guided to move and penetrate the soft tissue tunnel. The guide bar 20 is connected with a vacuum suction device, and the vacuum suction device is used to make the suction head 10 vacuum absorb and tightly wrap the stump of the nerve through the guide bar 20 . A negative pressure regulator 30 is communicated with the guide bar 20, and the negative pressure regulator 30 is used to manually adjust the suct...

Abstract

The invention discloses a nerve guiding device. The nerve guiding device comprises an adsorption head used for wrapping nerve broken ends of nerves to be dragged, the adsorption head communicates with a guiding strip, and the guiding strip is used for guiding the adsorption head to move and penetrate through a soft tissue tunnel under the action of external force. The guiding strip communicates with a vacuumizing adsorption device, and the vacuumizing adsorption device is used for enabling the adsorption head to adsorb and wrap the nerve broken ends in vacuum through the guiding strip. The guiding strip communicates with a negative pressure regulator, and the negative pressure regulator is used for manually regulating the adsorption force of the adsorption head for vacuum adsorption of the nerve broken ends. According to the nerve guiding device, in the traction process, the nerve broken ends can be protected through wrapping of the adsorption head, the nerve broken ends are prevented from being bruised and collided, the situation that the nerves are damaged due to external force compression or tearing can be effectively avoided, the adsorption force of the adsorption head for vacuumizing and adsorbing the nerve broken ends can be adaptively adjusted through the negative pressure regulator, so that the traction requirements of various nerve broken ends are met, and the application range of the nerve guiding device is widened.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a nerve guiding device. Background technique [0002] In nerve injury repair surgery, it often involves pulling the retracted nerve stump or the donor nerve used for nerve transfer to the predetermined anastomosis or bridge position through the soft tissue tunnel. At present, there is no dedicated nerve traction device clinically, and surgical clamps are often used to clamp or suture at the nerve stump and weave it into a wire harness to assist traction. [0003] During the clamping and traction of the suture bundle, there will inevitably be external pressure or tearing on the nerve, which will cause additional damage to the nerve tissue; when the sharp surgical clipper enters the soft tissue tunnel, it may injure other tissues, and the soft bundle itself passes through There are also operational difficulties in long soft tissue tunnels; in addition, during the process o...
