Description

Technical Field

[0001] This invention relates to the field of surgical instrument technology, specifically to a hemostatic forceps for thyroid surgery. Background Technology

[0002] The thyroid gland is a butterfly-shaped endocrine gland located in the front of the neck, directly in front of the trachea. Thyroid surgery, also known as thyroidectomy, is a surgical procedure aimed at removing all or part of the thyroid gland. Hemostatic forceps used in thyroid surgery are delicate surgical instruments specifically designed to clamp, compress, or temporarily block the thyroid gland and its surrounding rich blood vessels during thyroidectomy.

[0003] The existing hemostats have a relatively smooth inner ring, and when blood and tissue fluid soak into the instrument, the operator wearing sterile gloves is prone to slipping when holding it, resulting in insufficient instrument holding stability and posing a safety hazard. Summary of the Invention

[0004] The purpose of this invention is to provide a hemostatic forceps for thyroid surgery to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a hemostatic forceps for thyroid surgery, comprising a first forceps handle, a positioning pin, and a second forceps handle. The positioning pin is fixedly connected to the middle of the first forceps handle, and the second forceps handle is rotatably connected to the outer wall of the positioning pin. A first forceps head is connected to one side of the outer wall of the first forceps handle, and a first finger ring is connected to the other side of the outer wall of the first forceps handle. A second forceps head is connected to one side of the outer wall of the second forceps handle, and a second finger ring is connected to the other side of the outer wall of the second forceps handle. A first lock is fixedly connected to one side of the outer wall of the first finger ring, and a second lock is fixedly connected to one side of the outer wall of the second finger ring. A first protrusion is connected to the inner wall of the first finger ring, and a second protrusion is connected to the inner wall of the second finger ring. Anti-slip grooves are provided on the outer walls of both the first and second protrusions. The first protrusion is used to assist the ring finger in pushing the first clamp handle upward; the second protrusion is used to assist the thumb in pushing the second clamp handle downward; the anti-slip groove is used to increase the friction between the finger and the hemostat.

[0006] Preferably, both the first protrusion and the second protrusion are arc-shaped, the first latch and the second latch cooperate in a ratchet structure, and one side of the outer wall of both the first pliers and the second pliers is a toothed area.

[0007] When the ring finger is inside the first ring, the anti-slip groove on the outer wall of the first protrusion increases friction; when the thumb is inside the second ring, the anti-slip groove on the outer wall of the second protrusion increases friction, thus preventing slippage.

[0008] Preferably, the first pliers handle, the first pliers head, and the first finger ring form an integral structure, and the second pliers handle, the second pliers head, and the second finger ring form an integral structure.

[0009] Moving ring number one will cause plier handle number one and latch number one to move together. Moving ring number two will cause plier handle number two and latch number two to move together. At this time, plier handle number one and plier handle number two rotate around the positioning pin as the axis. At this time, plier head number one moves with plier handle number one and plier head number two moves with plier handle number two.

[0010] As can be seen from the above, the hemostatic forceps for thyroid surgery provided by the present invention have the following beneficial effects.

[0011] 1. The combination of the built-in protrusion and anti-slip groove in the ring increases the force-bearing area during operation, reduces finger load, and prevents slippage, thus improving the comfort and reliability of long-term surgical operations. In addition, the locking and unlocking operations are adapted to the natural movements of the surgeon's fingers, making the operation process smooth and reducing redundant steps in instrument operation.

[0012] 2. The locking mechanism can maintain continuous and stable clamping pressure, preventing blood vessels from loosening during clamping; the fine texture of the clamp head not only prevents small blood vessels from slipping but also disperses clamping stress, protecting the fragile blood vessel walls in the thyroid region and reducing intraoperative bleeding and tissue damage.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Please see Figures 1-7 The present invention provides a technical solution: a hemostatic forceps for thyroid surgery, comprising a first forceps handle 1, a positioning pin 2, and a second forceps handle 3. The positioning pin 2 is fixedly connected to the middle of the first forceps handle 1, and the second forceps handle 3 is rotatably connected to the outer wall of the positioning pin 2. A first forceps head 4 is connected to one side of the outer wall of the first forceps handle 1, and a first finger ring 5 is connected to the other side of the outer wall of the first forceps handle 1. A second forceps head 6 is connected to one side of the outer wall of the second forceps handle 3, and a second finger ring 7 is connected to the other side of the outer wall of the second forceps handle 3. A first lock 8 is fixedly connected to one side of the outer wall of the first finger ring 5, and a second lock 9 is fixedly connected to one side of the outer wall of the second finger ring 7. A first protrusion 10 is connected to the inner wall of the first finger ring 5, and a second protrusion 11 is connected to the inner wall of the second finger ring 7. Anti-slip grooves 12 are provided on the outer walls of both the first protrusion 10 and the second protrusion 11. The first protrusion 10 is used to assist the ring finger in pushing the first clamp handle 1 upward; the second protrusion 11 is used to assist the thumb in pushing the second clamp handle 3 downward; the anti-slip groove 12 is used to increase the friction between the finger and the hemostat. Both the first protrusion 10 and the second protrusion 11 are arc-shaped. The first latch 8 and the second latch 9 cooperate to form a ratchet structure. One side of the outer wall of the first pliers head 4 and the second pliers head 6 are toothed areas. The first pliers handle 1, the first pliers head 4 and the first finger ring 5 form an integrated structure. The second pliers handle 3, the second pliers head 6 and the second finger ring 7 form an integrated structure.

[0017] For specific implementation, please refer to Figure 1 and Figure 2 First, confirm that the hemostats are tightly engaged, the locking mechanism is flexible and without jamming, and the tip of the hemostat is not deformed. Then, the doctor inserts his thumb into the first ring 5 and his ring finger into the second ring 7, and moves the first ring 5 and the second ring 7 by moving the thumb and ring finger. See Figure 4 and Figure 6The operator adopts a standard grip posture: the ring finger is placed in ring 5 and the thumb is placed in ring 7. Through the coordinated movement of the thumb and ring finger, ring 5 and ring 7 are driven to produce relative displacement. The displacement of ring 5 is synchronized with the movement of handle 1 and latch 8, and the displacement of ring 7 is synchronized with the movement of handle 3 and latch 9. Handles 1 and 3 pivot around positioning pin 2, and the head 4 moves synchronously with handle 1 and the head 6 moves synchronously with handle 3. Through the aforementioned pivoting motion, the first clamp head 4 and the second clamp head 6 work together to perform a fine dissection of the thyroid capsule, and then clamp and occlude the target blood vessel. The ratio of the power arm, i.e. the handle section, to the resistance arm, i.e. the lever arm of the thyroid-specific hemostatic forceps, is configured as 3:1. With the help of the leverage amplification effect, the operator only needs to apply a small amount of finger force to achieve effective clamping of the forceps, avoiding the risk of loss of force control during fine operation. During the clamping process, the first locking buckle 8 and the second locking buckle 9 interlock with each other. After locking, the clamping pressure of the clamp head can be stably maintained without the operator having to continuously apply gripping force. At the same time, the surface of the clamp head is provided with fine interlocking texture, which can increase the friction with the target tissue / blood vessel and effectively prevent the slippage of small blood vessels with a diameter of <1mm. This texture structure can also disperse clamping stress and avoid damaging the fragile blood vessel walls in the thyroid area.

[0018] See Figure 5 and Figure 7 The first ring 5 integrates the first protrusion 10, and the second ring 7 integrates the second protrusion 11. When the ring finger is placed inside the first ring 5, the anti-slip groove 12 on the outer wall of the first protrusion 10 can increase the friction between the fingertip and the ring. When the thumb is placed inside the second ring 7, the anti-slip groove 12 on the outer wall of the second protrusion 11 similarly enhances the friction, thereby preventing slippage during operation.

[0019] See Figure 3 When it is necessary to release the clamp head, the operator pushes the first ring 5 upward with the ring finger, simultaneously moving the first clamp handle 1 upward; at the same time, the operator presses down on the second ring 7 with the thumb, simultaneously moving the second clamp handle 3 downward, so that the first lock 8 and the second lock 9 are disengaged. Among them, the first protrusion 10 can increase the force-bearing area when the ring finger pushes upward, and the second protrusion 11 can increase the force-bearing area when the thumb presses down, so that the operator can efficiently complete the lock separation operation.

[0020] This design combines a built-in protrusion in the ring with an anti-slip groove 12, which increases the force-bearing area during operation, reduces finger load, and prevents slippage, thus improving the comfort and reliability of long-term surgical operations. Furthermore, the locking and unlocking operations are adapted to the surgeon's natural finger movements, ensuring a smooth operation and reducing redundant steps in instrument operation.

[0021] The locking mechanism maintains continuous and stable clamping pressure, preventing blood vessels from slipping during clamping; the fine texture of the clamp head prevents small blood vessels from slipping and disperses clamping stress, protecting the fragile blood vessel walls in the thyroid region and reducing intraoperative bleeding and tissue damage.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made to the technical solutions and inventive concepts of the present invention should all be covered within the scope of protection of the present invention.
