[0002] In the repair and anastomosis of a ruptured lacrimal canaliculus, the ruptured medial canthal ligament needs to be repaired and sutured to reduce postoperative eyelid deformity complications. Currently, the common methods for traction and fixation of the nasal end of the medial canthal ligament during medial canthal ligament repair and suturing are to directly insert ophthalmic toothed forceps into the subcutaneous tissue to grasp the nasal end of the medial canthal ligament, or to cut open the skin and subcutaneous tissue on the surface of the nasal medial canthal ligament, separate the nasal end of the medial canthal ligament, and then insert sutures.

[0003] In medial canthal ligament rupture repair surgery, beginners often struggle to accurately fix the ligament's position before suturing. Using forceps can be difficult to maintain a stable and continuous grip on the ruptured ends. Furthermore, when using forceps to hold the ruptured ligament ends, obstructed vision or operational difficulties frequently lead to suturing deviations. This necessitates repeated adjustments to the gripping position and needle insertion direction during the procedure, prolonging the operation time and increasing the risk of tissue damage. Therefore, it is necessary to provide medial canthal ligament nasal lateral rupture end gripping and positioning suturing forceps with locking gripping and guide hole structures. With the help of the guide hole, needle insertion and suturing can be performed simultaneously with gripping and locking, avoiding repeated adjustments to the position and loss of control over the needle insertion direction, reducing operation time, and lowering the risk of tissue damage.

[0022] In the following description, embodiments of the medial canthal ligament nasal end clamping and positioning suture forceps of the present invention will be described with reference to the accompanying drawings.

[0023] Figure 1-4 This invention illustrates an embodiment of a medial canthal ligament nasal end clamping and positioning suture forceps, comprising a first rotating handle 1 and a second rotating handle 2. Clamping forceps plates 3 are fixedly connected to the top of both the first rotating handle 1 and the second rotating handle 2. A locking assembly 4 is provided between the first rotating handle 1 and the second rotating handle 2. The locking assembly 4 includes an elastic piece 41 located on one side of the second rotating handle 2. Two screws 43 are threadedly connected to the right side of the elastic piece 41, and the left end of each screw 43 extends through to the left side of the elastic piece 41 and is threadedly connected to the second rotating handle 2. An arc-shaped piece 42 is integrally formed on the top of the elastic piece 41. A locking pin 44 is fixedly connected to the side of the first rotating handle 1 near the second rotating handle 2. The arc-shaped piece 42 is sleeved on the surface of the locking pin 44. A positioning pin 5 is provided at the bottom between the first rotating handle 1 and the second rotating handle 2. The positioning pin 5 is fixedly connected to the first rotating handle 1, and the second rotating handle 2 is rotatably connected to the surface of the positioning pin 5. 2. Circular grooves 6 are provided on the bottom of opposite sides of each of the two circular grooves 6. A torsion spring 7 is provided in the inner cavity of the circular groove 6. The torsion spring 7 is sleeved on the surface of the positioning pin 5. The front end and rear end of the torsion spring 7 are welded to the inner walls of the two circular grooves 6 respectively. Through the cooperation of the positioning pin 5, the torsion spring 7, and the torsion spring 7, an elastic tension force is generated between the first rotating handle 1 and the second rotating handle 2. After a single clamping, the first rotating handle 1 and the second rotating handle 2 can drive the two clamping tweezer plates 3 to separate on their own, which is convenient for the user to clamp continuously. The top of the two clamping tweezer plates 3 on opposite sides is provided with serrated ridges 8. A guide hole 9 is provided on the top of the clamping tweezer plates 3. The surfaces of the first rotating handle 1 and the second rotating handle 2 are provided with anti-slip ridges 10. The anti-slip ridges 10 increase the friction between the first rotating handle 1 and the second rotating handle 2 and the user's hand, thereby improving the stability of the user in the process of controlling the first rotating handle 1 and the second rotating handle 2.

[0024] Working principle: When using this invention, the user controls the first rotating handle 1 and the second rotating handle 2 to move towards each other, causing the two clamping forceps 3 to move towards each other and clamp the ligament tissue. Simultaneously, during the relative movement of the first rotating handle 1 and the second rotating handle 2, the torsion spring 7 repeatedly contracts and expands, assisting in opening the two clamping forceps 3, facilitating continuous clamping of the ligament tissue. When clamping for a certain period is required, the user presses the first rotating handle 1 and the second rotating handle 2 towards each other, causing the locking pin 44 to press against the surface of the arc-shaped plate 42. The locking pin is influenced by the surface shape of the arc-shaped plate 42 and the elasticity of the elastic plate 41. The locking pin 44 moves to the left side of the elastic piece 41 and engages in the inner cavity of the arc-shaped piece 42, so that the angles of the first rotating handle 1 and the second rotating handle 2 are relatively fixed, thereby locking the clamping state of the ligament tissue by the two clamping forceps plates 3. At this time, the user can suture the ligament tissue by passing the needle through the inner cavity of the guide hole 9. After the operation is completed, the user presses the first rotating handle 1 and the second rotating handle 2 in opposite directions, so that the locking pin 44 disengages from the inner cavity of the arc-shaped piece 42, and moves the elastic piece 41 and the arc-shaped piece 42, so that the first rotating handle 1 and the second rotating handle 2 are separated, and the clamping forceps plates 3 are released from the clamping state.

[0025] In summary, this medial canthal ligament nasal end clamping and positioning suture forceps, through the combined use of the first rotating handle 1, the second rotating handle 2, and the clamping forceps plate 3, clamps the ligament tissue. Simultaneously, with the cooperation of the locking component 4, the clamping state of the retaining wall can be locked. The guide hole 9 facilitates the entry of the suture needle and the adjustment of the needle angle, thus achieving the purpose of precise and convenient clamping and easy control of the needle insertion direction.
