Description

Technical Field

[0001] The utility model is applicable to the technical field of medical devices and provides a hemostatic forceps. Background Technique

[0002] A hemostatic forceps is a medical tool used to control bleeding during surgical operations and other medical procedures. It is usually made of stainless steel or other corrosion-resistant materials and has two movable handles and a pair of lockable clamping heads. The main function of the hemostatic forceps is to effectively stop bleeding or reduce bleeding by clamping blood vessels or tissues around the blood vessels.

[0003] In order to correctly use the hemostatic forceps, medical staff will select a suitable hemostatic forceps according to the type of surgery or operation to ensure that its size and shape are suitable for the target tissue; at the same time, during the use process, the handle of the hemostatic forceps needs to be correctly held so that the opening and closing actions of the handle are flexible and easy to control, and the hemostatic forceps can be accurately clamped near the blood vessels or tissues that need to stop bleeding, ensuring that the clamping heads are completely closed to achieve the hemostatic effect; after clamping the blood vessels or tissues, lock the clamping heads of the hemostatic forceps to ensure that they are firmly held in place to prevent the blood vessels from reopening or moving.

[0004] Although hemostatic forceps are widely used in medical practice, there is a common problem with some hemostatic forceps on the market at present: after coming into contact with blood, the surface of the hemostatic forceps easily becomes slippery, resulting in medical staff losing effective control of the tool during the operation. Especially in some incorrect holding postures, such as under the slippery surface of gloves or the operation area, this problem may be further exacerbated, increasing the risk of accidents or delays in medical operations. Content of the Utility Model

[0005] In view of the above defects, the purpose of the utility model is to provide a hemostatic forceps, aiming to solve the problems raised in the background technique. The device includes a first forceps body and a second forceps body hinged through a hinged structure.

[0023] One end of the first hinge portion 14 away from the first pliers body 1 is fixedly connected to a first jaw 13; one end of the second hinge portion 24 away from the second pliers body 2 is fixedly connected to a second jaw 23. One ends of the first pliers body 1 and the second pliers body 2 away from the hinge structure are respectively fixedly connected to a first ring sleeve 11 and a second ring sleeve 21, and the circular surfaces of the first ring sleeve 11 and the second ring sleeve 21 are parallel to each other.

[0024] On one side of the first pliers body 1 close to the second pliers body 2, a first locking tooth 12 is fixedly connected; on one side of the second pliers body 2 close to the first pliers body 1, a second locking tooth 22 is fixedly connected. The first locking tooth 12 and the second locking tooth 22 are both provided with tooth-shaped structures, and the tooth-shaped structures of the two can be engaged with each other to lock the hemostat after the first jaw 13 and the second jaw 23 clamp the blood vessel or tissue, ensuring that the first jaw 13 and the second jaw 23 are firmly held in position to prevent the blood vessel from reopening or moving.

[0025] One end of the first ring sleeve 11 away from the first pliers body 1 is fixedly connected to a palm rest 110, and an arc-shaped structure is provided on one side of the palm rest 110 away from the first ring sleeve 11; specifically, the arc portion of the arc-shaped structure is concave inward in the direction close to the first ring sleeve 11, and the arc-shaped structure and the palm rest 110 have a fillet transition.

[0026] On one side of the first pliers body 1 away from the second pliers body 2, a first contact portion 101 is provided. The first contact portion 101 is an arc-shaped groove provided on one side of the first pliers body 1; specifically, the depth of the lowest concave portion of the first contact portion 101 is 1.2 mm. Taking the arc on the arc-shaped groove surface of the first contact portion 101 as a secant line, the two ends of the secant line are respectively located at the junction of the first contact portion 101 and the first pliers body 1, and the length of this secant line is 12 mm.

[0027] Preferably, the surface of the first contact portion 101 is provided with a rough surface; the rough surface of the first contact portion 101 can specifically be fine tooth grooves formed by mechanical grinding, or a rough surface formed by laser or chemical etching technology. The rough surface can increase the friction with the glove, and even if there is blood splashing on the first contact portion 101, a certain friction can still be maintained between the gloves to prevent slipping during the hemostasis operation.

[0028] On the second pliers body 2, a second contact portion 201 is provided. The second contact portion 201 is an arc-shaped groove provided on one side of the second pliers body 2; specifically, the depth of the lowest concave portion of the second contact portion 201 is 1.4 mm. Taking the arc on the arc-shaped groove surface of the second contact portion 201 as a secant line, the two ends of the secant line are respectively located at the junction of the second contact portion 201 and the second pliers body 2, and the length of this secant line is 18 mm.

[0029] Preferably, the surface of the second contact part 201 is provided with a rough surface; the rough surface of the second contact part 201 can specifically be fine tooth grooves formed by mechanical grinding, or a rough surface formed by laser or chemical etching technology. The rough surface can increase the friction with the glove, so that even if blood splashes on the second contact part 201, a certain friction can still be maintained between the gloves, preventing slipping during the hemostasis operation.

[0030] Preferably, the first jaw 13, the first hinge part 14, the first pliers body 1, the first cogs 12, the first ring sleeve 11 and the palm rest 110 are of an integrally formed stainless steel structure. The second jaw 23, the second hinge part 24, the second pliers body 2, the second cogs 22 and the second ring sleeve 21 are of an integrally formed stainless steel structure. This method can make the hemostatic forceps easy to disinfect and clean, reduce gaps, and prevent the residue of bacteria and viruses.

[0031] In summary, during actual use, the user operates the hemostatic forceps with the right hand. The user's right thumb passes through the second ring sleeve 21, and the ring finger of the right hand passes through the first ring sleeve 11 forward or backward. Thus, it can be ensured that the opening and closing of the two jaws of the hemostatic forceps can be controlled by the opening and closing of two fingers. When holding the instrument, the correct holding method requires pressing the pulp of the index finger on the second pliers body 2, and at the same time, the second phalanx of the middle finger is pushed upward against the part of the first pliers body 1 close to the first ring sleeve 11. In this technical solution, under the condition of standard holding, the second contact part 201 and the first contact part 101 are respectively arranged at the contact positions of the index finger and the middle finger with the hemostatic forceps. Thus, it can form a certain psychological hint for the operator, teach the user to maintain the standard holding posture of the instrument, and also play a good teaching role for novices. At the same time, the second contact part 201 and the first contact part 101 are provided with rough surfaces, which can play an anti-slip role, and can also ensure that there is no slippage between the two when blood splashes between the finger and the hemostatic forceps.
