Description

Technical Field

[0001] This utility model relates to a chopstick-type microscissors, belonging to the field of medical device technology. Background Technology

[0002] Microsurgical scissors, also known as microsurgical scissors, are medical instruments used for precisely trimming blood vessels, nerve tissue, or separating tissue spaces during microsurgery.

[0003] Microsurgical scissors typically consist of two symmetrical L-shaped scissor bodies. The long ends of the two L-shaped scissor bodies are made into scissor blades and are connected by a pin, so the overall shape of the microsurgical scissors is X-shaped.

[0004] Microsurgical shears are used to trim and separate blood vessels, nerves, lymphatic vessels, etc. They are mainly used for the gentle separation of small or large blood vessels and nerves, and can also be used as a suture cutting tool for 5 / 0 to 11 / 0 lines.

[0005] Microsurgical scissors typically use a spring-loaded opening and closing mechanism. The spring should not be too tight, as this can cause hand fatigue and hinder surgery; if the spring is too loose, it can easily slip off when held and may even cause blood vessel tearing.

[0006] The existing microscissors are spring-loaded microscissors, which are operated by pinching them with the thumb and forefinger. A certain amount of finger strength is required to resist the elastic force, and the elastic force increases with deformation. The force required by the fingers also gradually increases. If the finger strength is insufficient, the scissors are prone to shaking after pinching the tissue, which affects the stability of fiber handling. Utility Model Content

[0007] The technical problem to be solved by this utility model is to propose a chopstick-type micro scissors that can be operated with four fingers, has good stability, can apply force steadily, and can easily control the cutting and extension of the blade. Even without systematic micro scissor operation training, one can stably operate the chopstick-type fiber scissors of this utility model; and it is labor-saving to operate and will not cause hand fatigue.

[0008] In order to solve the technical problem of the present invention, the proposed technical solution is: a chopstick-type micro scissors, including a micro scissor head (1), a first scissor handle (2), a second scissor handle (3), a first limiting ring (4), and a second limiting ring (5);

[0009] The micro scissor head (1) has a scissor structure, with a micro scissor (1-1) at the front, a hinge (1-2) in the middle, and a first scissor handle (1-3) and a second scissor handle (1-4) at the rear.

[0010] The first scissor handle (2) is a cylindrical structure and is fixedly connected to the first scissor handle (1-3); the second scissor handle (3) is a cylindrical structure and is fixedly connected to the second scissor handle (1-4);

[0011] Below the first limiting ring (4) is the first limiting barrel (4-1), and above it is the first limiting ring (4-2); the first limiting barrel (4-1) is a cylindrical structure, nested in the middle of the first scissor handle (2), and the first limiting ring (4-2) is a ring structure, fixedly installed with the first limiting barrel (4-1); the normal of the ring plane of the first limiting ring (4-2) is perpendicular to the central axis of the first limiting barrel (4-1);

[0012] Below the second limiting ring (5) is the second limiting barrel (5-1), and above it is the second limiting ring (5-2); the second limiting barrel (5-1) is a cylindrical structure, nested in the middle of the second scissor handle (3), and the second limiting ring (5-2) is a ring structure, fixedly installed with the second limiting barrel (5-1); the normal of the ring plane of the second limiting ring (5-2) is parallel to the central axis of the second limiting barrel (5-1).

[0013] Preferably, the main body of the first scissor handle (2) and the second scissor handle (3) is straight or Z-shaped.

[0014] Preferably, the number of second limiting rings (5) is 2.

[0015] Preferably, when the first limiting barrel (4-1) is nested on the first scissor handle (2), it has frictional resistance, which can limit its rotation and axial movement.

[0016] Preferably, when the second limiting barrel (5-1) is nested on the second scissor handle (3), it has frictional resistance, which can limit its rotation and axial movement.

[0017] Beneficial effects:

[0018] 1. The chopstick-type micro scissors of this utility model have good stability, allowing medical staff to apply force steadily and easily control the cutting and extension of the blade. Even without systematic micro scissor operation training, they can stably operate the chopstick-type fiber scissors of this utility model.

[0019] 2. The chopstick-type micro scissors of this utility model do not require the use of springs or the work of overcoming elasticity. The opening and closing of the front part of the scissors is completely operated and stably controlled by the four fingers of the index finger, thumb, middle finger and ring finger.

[0020] 3. When medical staff place three fingers inside the limiting ring, they feel as if their hand and the instrument are integrated, making the operation very stable and effortless, without causing hand fatigue. Attached Figure Description

[0023] Example 1

[0024] A chopstick-type micro scissors includes a micro scissor head 1, a first scissor handle 2, a second scissor handle 3, a first limiting ring 4, and a second limiting ring 5;

[0025] The micro scissor head 1 has a scissor structure, with a micro scissor 1-1 at the front, a hinge 1-2 in the middle, and a first scissor handle 1-3 and a second scissor handle 1-4 at the rear.

[0026] The first scissor handle 2 is a cylindrical structure and is fixedly connected to the first scissor handle 1-3; the second scissor handle 3 is a cylindrical structure and is fixedly connected to the second scissor handle 1-4.

[0027] Below the first limiting ring 4 is the first limiting barrel 4-1, and above it is the first limiting ring 4-2; the first limiting barrel 4-1 is a cylindrical structure, nested and installed in the middle of the first scissor handle 2, and the first limiting ring 4-2 is a ring structure, fixedly installed with the first limiting barrel 4-1; the normal line of the ring plane of the first limiting ring 4-2 is perpendicular to the central axis of the first limiting barrel 4-1;

[0028] Below the second limiting ring 5 is the second limiting barrel 5-1, and above it is the second limiting ring 5-2; the second limiting barrel 5-1 is a cylindrical structure, nested and installed in the middle of the second scissor handle 3, and the second limiting ring 5-2 is a ring structure, fixedly installed with the second limiting barrel 5-1; the normal line of the ring plane of the second limiting ring 5-2 is parallel to the central axis of the second limiting barrel 5-1.

[0029] The main body of the first scissor handle 2 and the second scissor handle 3 is Z-shaped.

[0030] There are two second limiting rings 5, which are arranged alternately. When the surgeon puts three fingers into the first limiting ring 4 and the second limiting ring 5, it feels like the hand and the instrument are integrated, and the operation is very stable.

[0031] When the first limiting barrel 4-1 is nested on the first scissor handle 2, it has frictional resistance, which can limit its rotation and axial movement.
