Abstract

A fibrocartilage suturing device is provided to solve the problem where the conventional procedure of the surgery is inconvenient. The fibrocartilage suturing device includes a tube assembly, a tubular member, and an anchor. The tube assembly extends through the tube assembly and includes an insertion section. The movement member is coupled with the tube assembly and includes a thrust rod extending through the tubular member. The anchor is located at one end of the thrust rod and includes a body and at least two wings connected to the body is able to be folded and unfolded relative to the body. The body of the anchor is connected to an end of a thread. Another end of the thread is connected to the tubular member.

First claim

What is claimed is:

1. A fibrocartilage suturing device, comprising:
a tube assembly ( 1 ) having a first tube unit ( 1 a ) and a second tube unit ( 1 b ) wherein a first coupling portion ( 11 ) of the first tube unit ( 1 a ) is directly threaded with a second coupling portion ( 12 ) of the second tube unit ( 1 b ), wherein the tube assembly ( 1 ) has a tube portion ( 15 ) at the second tube unit ( 1 b );
a tubular member ( 2 ) extending through the tube assembly ( 1 ) and including an insertion section ( 22 );
a movement member ( 3 ) coupled with the tube assembly ( 1 ) and including a thrust rod ( 32 ) extending through the tubular member ( 2 ); and
an anchor ( 4 ) located at one end of the thrust rod ( 32 ) and including a body ( 41 ) and at least two wings ( 42 ) connected to the body ( 41 ), wherein each of the at least two wings ( 42 ) is able to be folded and unfolded relatively to the body ( 41 ), and wherein the body ( 41 ) of the anchor ( 4 ) is connected to an end of a thread (L), and another end of the thread (L) is connected to the tubular member ( 2 );
wherein by turning the second tube unit ( 1 b ), the insertion section ( 22 ) of the tubular member ( 2 ) has an adjustable length exposed outside of the tube portion ( 15 ).

2. The fibrocartilage suturing device as claimed in claim 1 , wherein the tubular member ( 2 ) has a thread hole ( 23 ) and a wire-fixing portion ( 24 ), wherein the thread (L) passes through the thread hole ( 23 ) within the tubular member ( 2 ), and wherein the thread (L) is exposed partially outside of the tubular member ( 2 ) and is connected to the wire-fixing portion ( 24 ).

3. The fibrocartilage suturing device as claimed in claim 1 , wherein the movement member ( 3 ) has a handgrip ( 31 ) connected to the thrust rod ( 32 ), wherein the handgrip ( 31 ) has two groove portions ( 311 ) respectively connected to two guiding rails ( 14 ) of the tube assembly ( 1 ), and wherein a thickness of the handgrip ( 31 ) reduces from one end to another end thereof.

4. The fibrocartilage suturing device as claimed in claim 1 , wherein an angle (θ) is formed between each of the at least two wings ( 42 ) and is smaller than 180°.

5. The fibrocartilage suturing device as claimed in claim 1 , wherein an outer surface of the body ( 41 ) has at least two reduced portions ( 411 ) respectively corresponding to the at least two wings ( 42 ).

6. The fibrocartilage suturing device as claimed in claim 1 , wherein as each of the at least two wings ( 42 ) is in an unfolded state relative to the body ( 41 ), an angle (α) is formed between each of the at least two wings ( 42 ) and a central axis (X) of the anchor ( 4 ), and wherein 15°≤angle (α)≤90°.

7. The fibrocartilage suturing device as claimed in claim 6 , wherein the body ( 41 ) is integrally formed with the at least two wings ( 42 ).

8. The fibrocartilage suturing device as claimed in claim 6 , wherein the body ( 41 ) is in an arc shape.
