Description

Technical Field

[0001] The utility model relates to a hemostatic forceps, in particular to a hemostatic forceps device used in hepatobiliary surgery. Background Art

[0002] Accurate hemostasis of blood vessels is crucial in hepatobiliary surgery. Traditional hemostatic forceps often have difficulty precisely controlling the clamping force, which can lead to excessive damage to blood vessels during surgery, compromising surgical outcomes and increasing the patient's risk of postoperative complications. Furthermore, the simple joint design of traditional hemostatic forceps makes them inflexible during operation, making them difficult to adapt to the diverse demands for clamping angles and force in different surgical scenarios.

[0003] With the continuous advancement of medical technology, the requirements for hemostatic forceps in hepatobiliary surgery are becoming increasingly higher. Therefore, there is an urgent need for a better hemostatic forceps device for hepatobiliary surgery on the market. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the defects of the above-mentioned technology and provide a hemostatic forceps device for hepatobiliary surgery.

[0005] In order to solve the above technical problems, the technical solution provided by the present invention is a hemostatic forceps device for hepatobiliary surgery: comprising a first forceps body and a second forceps body;

[0006] The joint of the first clamp body is a plate-shaped joint;

[0007] The joint of the second clamp body is a long hole joint;

[0008] The plate-like joint passes through the long hole joint, and the middle part of the plate-like joint and the middle part of the long hole joint are rotatably matched through a hinged connection. A guide tube body is fixedly provided on the long hole joint near the second finger ring, and the extension direction of the guide tube body is toward the long hole joint. A small nut is fixedly provided on the outer end of the guide tube body, and a clamping screw is provided on the small nut. The stud part on the clamping screw and the small nut are threadedly matched, and the end of the stud part on the clamping screw serves to limit the rotation of the plate-like joint.

[0009] As an improvement, friction lines are provided on the edge of the handle portion of the clamping screw.

[0010] As an improvement, the plate-shaped joint is close to the first clamping beak on the first pliers body, and the distance between the plate-shaped joint and the first clamping beak is smaller than the distance between the plate-shaped joint and the first finger ring on the first pliers body.

[0011] As an improvement, the elongated hole joint is close to the second clamping beak on the second pliers body; the distance between the elongated hole joint and the second clamping beak is smaller than the distance between the elongated hole joint and the second finger ring on the second pliers body.

[0012] The advantages of this new device over existing technologies include precise control of clamping force: By rotating the clamping screw, the degree of clamping force between the first and second clamping beaks on the blood vessel can be precisely adjusted. Tightening the clamping screw gradually reduces the clamping force to avoid over-clamping and damage to the blood vessel; loosening the clamping screw increases the clamping force, meeting the needs of different situations and achieving precise control of the clamping force. The coordinated design of the plate-shaped joint and the elongated hole joint allows for corresponding rotation according to the clamping force and angle, making the clamping process more flexible and adaptable to different surgical operation scenarios.

[0013] Safe and reliable: Precise clamping force control can effectively avoid blood vessel damage caused by excessive clamping, reducing surgical risks and improving surgical safety.

[0014] The device has a reasonable structural design and its components work closely together, ensuring stability and reliability during the operation and providing strong support for hepatobiliary surgery. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, it should not be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0023] Furthermore, the use of terms such as "horizontal," "vertical," and "overhanging" does not necessarily imply that the component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0024] In the description of the embodiments of the present invention, “a plurality of” means at least 2.

[0025] In the description of the embodiments of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0026] With reference to the accompanying drawings, a hemostatic forceps device for hepatobiliary surgery includes a first forceps body 1 and a second forceps body 2;

[0027] The joint of the first pliers body 1 is a plate-shaped joint 3, which is close to the first clamping beak 4 on the first pliers body 1. The distance between the plate-shaped joint 3 and the first clamping beak 4 is smaller than the distance between the plate-shaped joint 3 and the first finger ring 5 on the first pliers body 1.

[0028] The joint of the second pliers body 2 is a long hole joint 6, which is close to the second clamping beak 7 on the second pliers body 2; the distance between the long hole joint 6 and the second clamping beak 7 is smaller than the distance between the long hole joint 6 and the second finger ring 8 on the second pliers body 2;

[0029] The plate-shaped joint 3 passes through the long hole joint 6, and the middle part of the plate-shaped joint 3 and the middle part of the long hole joint 6 are rotated and matched by a hinged connection. A guide tube body 9 is fixedly provided on the long hole joint 6 at the part close to the second finger ring 8, and the extension direction of the guide tube body 9 is toward the long hole joint 6. A small nut 10 is fixedly provided at the outer end of the guide tube body 9, and a clamping screw 11 is provided on the small nut 10. The stud part on the clamping screw 11 and the small nut 10 are threadedly matched. The end of the stud part on the clamping screw 11 plays a role in limiting the rotation of the plate-shaped joint 3. The purpose is to limit the clamping of the blood vessels between the first clamping beak 4 on the first clamp body 1 and the second clamping beak 7 on the second clamp body 2 by limiting the rotation between the plate-shaped joint 3 and the long hole joint 6, so as to avoid excessive clamping and damage to the blood vessels.

[0030] The edge of the handle portion 12 of the clamping screw 11 is provided with friction lines 13 to achieve better effect.

[0031] First, the user inserts their fingers through the first finger loop 5 of the first clamp body 1 and the second finger loop 8 of the second clamp body 2. Next, they begin clamping the blood vessel. Through the movement of their fingers, the first and second clamping beaks 4 and 7 approach each other, clamping the blood vessel or the area requiring hemostasis. During this process, the plate joint 3 and the elongated hole joint 6 rotate accordingly based on the force and angle of the clamp.

[0032] If the clamping force needs to be adjusted, this can be achieved by rotating the clamping screw 11. As the clamping screw 11 is tightened, the end of the stud gradually approaches the plate joint 3, thereby restricting its rotation. This reduces the angle between the first clamping beak 4 and the second clamping beak 7, further reducing the clamping force and preventing damage to blood vessels due to over-clamping. Conversely, when the clamping screw 11 is loosened, the rotational restriction between the plate joint 3 and the elongated hole joint 6 is reduced, and the clamping force is correspondingly increased. This adjustment can be made based on actual usage to ensure safe use.

[0033] In addition, since the edge of the handle portion 12 of the clamping screw 11 is provided with friction grooves 13, when rotating the clamping screw 11, the fingers can better grip the handle portion 12, thereby increasing the stability and convenience of the operation.

[0034] Precisely control the clamping force: By rotating the clamping screw 11, the degree of clamping force between the first and second clamping beaks 4 and 7 can be precisely adjusted. Tightening the clamping screw 11 gradually reduces the clamping force to prevent over-clamping and damage to the vessel; loosening the clamping screw 11 increases the clamping force to meet the needs of different situations, achieving precise control of the clamping force. The coordinated design of the plate joint 3 and the elongated hole joint 6 allows for corresponding rotation according to the clamping force and angle, making the clamping process more flexible and adaptable to different surgical operation scenarios.

[0035] Safe and reliable: Precise clamping force control can effectively avoid blood vessel damage caused by excessive clamping, reducing surgical risks and improving surgical safety.

[0036] The device has a reasonable structural design and its components work closely together, ensuring stability and reliability during the operation and providing strong support for hepatobiliary surgery.

[0037] Convenient and efficient operation: The user simply inserts their fingers through the first finger ring 5 of the first clamp body 1 and the second finger ring 8 of the second clamp body 2 to easily operate the hemostat for clamping. Friction grooves 13 are provided on the edge of the handle portion 12 of the clamping screw 11, allowing the fingers to better grip the handle portion 12 when rotating the clamping screw 11, increasing operational stability and convenience, and improving surgical efficiency.

[0038] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
