Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more particularly to an anastomosis device for repairing and reconstructing the recurrent laryngeal nerve. Background Art

[0002] In recent years, the incidence of thyroid cancer has increased explosively, and it is becoming more and more common for locally advanced thyroid cancer to invade the recurrent laryngeal nerve. After tumor resection, the defective ends of the recurrent laryngeal nerve need to be reconstructed. The current conventional method is to use sutures to intermittently pull and suture. Although this method seems to physically reconnect the nerve, the functional recovery effect of the recurrent laryngeal nerve is often unsatisfactory. Therefore, we proposed an anastomosis device for the repair and reconstruction of the recurrent laryngeal nerve. Summary of the invention

[0003] In order to solve the above problems, the present invention provides an anastomosis device for repairing and reconstructing the recurrent laryngeal nerve, which adopts the following technical solution:

[0004] An anastomosis device for repairing and reconstructing a recurrent laryngeal nerve comprises two symmetrically distributed collars and a mounting box located on one side of the two collars, a plurality of fixing pins distributed in a ring array are arranged on opposite sides of the two collars, the two groups of fixing pins are staggered, fixing grooves matching the fixing pins are opened on opposite sides of the two collars, limiting components are arranged in the two collars, first half-rings are fixedly installed on opposite sides of the two collars, and second half-rings are hinged on one side of the two first half-rings;

[0005] Two symmetrically distributed moving grooves are provided on the side of the installation box close to the collar, and moving blocks are slidably installed in the two moving grooves. Connecting blocks are fixedly installed on the opposite sides of the two moving blocks. Elastic splints matching the collar are fixedly installed on the sides of the two connecting blocks away from the installation box, and a driving assembly is provided between the ends of the two moving blocks away from the collar.

[0006] By adopting the above technical solution, when the device is used, the staff places the ring inside the elastic splint, and the elastic splint can play the role of clamping the ring. After the ring is clamped, the staff places the ring in the patient's body to place the nerve inside the ring. A limiting component is provided inside the ring to play the role of limiting and clamping the nerve, and the nerve is placed inside the first half ring installed on one side of the ring. Subsequently, by flipping the second half ring, the second half ring is fitted with the first half ring on the same side to form a tube, which can further clamp and fix the nerve and facilitate subsequent docking.

[0007] When the two sections of nerve are clamped, the two moving blocks are driven to move relative to each other through the driving assembly, and the moving blocks move synchronously with the ipsilateral connecting block, the elastic splint and the ring, so that the two rings move relative to and contact with the ipsilateral nerve ends, thereby playing the role of splicing the nerves. When the two rings are in contact, the fixing pin installed on one side of the ring is engaged with the fixing groove opened on the side wall of the other ring, thereby playing the role of assembling the two rings. The nerves are connected by docking the two rings, so that the two nerve ends are docked and anastomosed, so that the neatness and continuity of the anastomosis are better, which is beneficial to the recovery of the recurrent laryngeal nerve function.

[0008] Furthermore, the limiting assembly includes a plurality of limiting clamps in a ring distributed in a circular array, a plurality of movable grooves distributed in a circular array are opened on the inner sides of the two rings, elastic blocks are provided in the movable grooves, the ends of the elastic blocks on the same side are fixedly connected to the side opposite to the limiting clamps on the same side, and a plurality of first protrusions distributed in an arc-shaped array are provided on the side of the limiting clamp away from the elastic blocks on the same side.

[0009] By adopting the above technical solution, the staff places the nerve in the ring, and a limiting splint is provided in the ring. The limiting splint fits precisely with the side wall of the nerve under the elastic force of the elastic block on the same side. Through the cooperation of multiple elastic blocks and the limiting splint, the nerve is clamped and fixed. A first convex point is provided on the inner side of the limiting splint, which is beneficial to increase the friction between the limiting splint and the nerve, thereby helping to improve the stability of the device in clamping the nerve.

[0010] Furthermore, the driving assembly includes a double-thread screw rotatably installed in the installation box, a turbine is fixedly sleeved on the side wall of the double-thread screw, a vortex is rotatably installed in the installation box, the vortex and the turbine are meshed, two moving blocks are sleeved on the side wall of the double-thread screw at one end away from the collar, a sleeve is fixedly installed on the side of the installation box away from the collar, a rotating rod is rotatably installed in the sleeve, the rotating rod rotates at one end close to the collar and passes through the installation box, and one end of the rotating rod passes through the installation box and is fixedly connected to the end opposite to the vortex.

[0011] By adopting the above technical solution, when the nerves at both ends are clamped, the rotating rod is manually rotated, the rotating rod drives the vortex rod to rotate, the vortex rod drives the turbine to rotate, the turbine drives the double-tooth screw to rotate, the double-tooth screw drives the two moving blocks to move synchronously, and the moving block moves synchronously with the connecting block, elastic splint and ring on the same side, so that the two rings move relative to and contact the nerve ends on the same side, thereby playing the role of splicing the nerves.

[0012] Furthermore, a stabilizing rod is fixedly installed in the installation box, and the ends of the two moving blocks away from the collar are slidably sleeved with side walls of the stabilizing rod.

[0013] By adopting the above technical solution, when the double-thread screw drives the two moving blocks to move, the two moving blocks slide on the stabilizing rod. The stabilizing rod is set to balance the moving blocks, which is beneficial to maintaining the stability of the movement of the two moving blocks.

[0014] Furthermore, a plurality of plug rods distributed in a linear array are fixedly installed on one side of the two second semi-rings, a slot matching the plug rods on the same side is opened at the top of one side of the first semi-ring, and a plurality of second protrusions distributed in an arc-shaped array are fixedly installed on the inner sides of the first semi-ring and the second semi-ring, and a convex cone is provided on the top of the second protrusion.

[0015] By adopting the above technical solution, after the staff places the nerve on the first half ring, the staff flips the second half ring so that the second half ring fits together with the first half ring on the same side to form a tube, which can play the role of clamping and fixing the nerve, and a plug rod is provided on one side of the second half ring. The plug rod and the slot opened on the side of the first half ring on the same side are engaged, which is conducive to improving the stability of the splicing of the first half ring and the second half ring on the same side. Second convex points are provided on the inner sides of the first half ring and the second half ring, and convex cones are provided on the tops of the second convex points. The cooperation of the second convex points and the convex cones is conducive to improving the stability of the equipment in clamping the nerve, which is convenient for subsequent stable docking.

[0016] Furthermore, positioning rods are fixedly installed on one side of the two elastic clamps close to the collar, and positioning holes matching the positioning rods are opened on the side walls of the two collars.

[0017] By adopting the above technical solution, when the collar is placed in the elastic clamp, a positioning rod is provided on the inner side of the elastic clamp, and the positioning rod is engaged with the positioning hole provided in the side wall of the collar to achieve the positioning effect.

[0018] Furthermore, two symmetrically distributed limiting rings are fixedly mounted on the side walls of the two collars.

[0019] By adopting the above technical solution, the two side walls of the collars play a role of limiting the elastic splints through the arrangement of two limiting rings, which helps to prevent the collars from slipping.

[0020] In summary, the present invention includes the following beneficial technical effects:

[0021] (1) In the present invention, two rings are provided, and a limiting assembly is provided inside the rings to clamp and locate the nerves. In addition, the opposite sides of the two rings cooperate with the first half ring and the second half ring to further clamp and fix the nerves, which is convenient for subsequent docking.

[0022] (2) In the present invention, by cooperating with the driving assembly and the elastic splint, the ring is clamped by the elastic splint, and then the two rings are driven by the driving assembly to move relative to each other, so as to achieve the function of docking the nerves. By cooperating with the fixing pin and the fixing groove, the two rings can be assembled, thereby achieving the function of docking the nerves.

[0023] (3) In the present invention, nerve growth factor is added to the inside of the limiting splint, the first half ring and the second half ring, which continuously acts on the anastomotic ends, thereby accelerating the recovery of the recurrent laryngeal nerve function. The nerves are connected by docking the two rings so that the two nerve ends are docked and anastomosed, which improves the neatness and continuity of the anastomosis and is beneficial to the recovery of the recurrent laryngeal nerve function.
