Detailed Description

The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention. Unless otherwise specified, the technical means used in the examples are conventional means well known to those skilled in the art.

As shown in fig. 1 to 6, the jugular vein retractor for thyroid surgery according to the embodiment of the present invention comprises a first portion 10 and a second portion 20 connected to each other. Wherein, the first portion 10 is rod-shaped or bar-shaped. The second part 20 comprises a bent section 21, the bent section 21 is in a hook shape and is arranged at the end of the second part 20, the first end of the bent section is close to the first part, and the second end of the bent section is far away from the first part; the width of the developed surface of the bent section 21 is gradually increased in the development direction from the first end to the second end. In thyroid surgery, it is sometimes necessary to clean the cervical lateral lymph node, and since some lymph nodes are located laterally and posteriorly (in the direction of observation during surgery) of the jugular vein, the jugular vein must be pulled inward to expose the visual field. The specific operation method comprises the following steps: in operation, the first portion 10 is held by hand, the bend 21 of the second portion is carefully inserted into the surgical area and the jugular vein is pulled inward to expose the lymph node.

In a preferred embodiment, as shown in fig. 1-6, the second portion 20 further comprises a straight section 22, one end of the straight section 22 is connected to one end of the first portion 10, and the other end of the straight section 22 is connected to the bent section 21. The straight section 22 is used for connecting the first part 10 and the bent section 21, so that good transition between the two is realized, and the integral shape is more attractive and smooth. For example, when the width of the first portion 10 is relatively small and the end of the bent section 21 near the first portion 10 is relatively wide, a smooth transition may be made through the straight section 22.

In a preferred embodiment, as shown in fig. 5-6, the development of the curved section 21 can be fan-shaped or trapezoidal. The fan-shaped expansion surface has the characteristics of beautiful lines, natural smoothness and symmetry, as shown in fig. 6. The development of the trapezium can be an isosceles trapezium, as shown in fig. 5. Both scallops and trapezoids are common shapes and meet the need for a width that increases progressively in the direction of the flare from the first end to the second end.

In a preferred embodiment, as shown in FIG. 2, the first portion 10 has an arcuate configuration that conforms to the internal anatomy of the human body. According to the physiological anatomy characteristics of the neck, the first part 10 has bionic physiological bending and conforms to the physiological structure of a human body, so that a surrounding uplifted trachea can be avoided accurately, and the surgical field and the traction effect are ensured.

In a preferred embodiment, as shown in fig. 3-4, the other end of the first portion 10 may be provided with a fixing means 11. For example, the fixing device 11 may be a fixing hole provided at the other end of the first portion 10, or may be a fixing tab. Through the fixing device 11, the utility model can be fixedly arranged at the position convenient for operation. For example, the jugular vein retractor for thyroid surgery can be fixed on the surgical drape through a rubber band on the fixing hole or the fixing pull ring. Of course, direct manual pulling is also possible. By utilizing the fixing function of the fixing device 11, the surgical field can be fully exposed, the surgical safety is ensured, and simultaneously, the labor can be greatly saved, so that the surgical operation is simpler and more convenient.

In a preferred embodiment, as shown in fig. 2-4, the first portion 10 can be a flat bar, so that the fingers can grip the first portion 10 more easily, and the first portion is ergonomically designed, so that the operation is more comfortable and the gripping is more stable. The second portion 20 is matched with the first portion 10 in a flat strip shape, that is, the second portion 20 can also be in a flat shape, so that the structure is smooth, the space is saved, and the operation is more flexible and convenient.

In a preferred embodiment, as shown in fig. 5-6, the adjacent edges of the extended surface of the curved section 21 may be in a circular arc transition to avoid sharp edges and scratches on the tissues such as blood vessels or trachea during the operation.

In a preferred embodiment, as shown in fig. 1-6, the junction between the first portion 10 and the second portion 20 may be a smooth transition to avoid sharp edges and scratches on tissues such as blood vessels or trachea during surgery, and make the whole body more beautiful and elegant. In addition, all parts with edges of the whole structure need to be in circular arc smooth transition, so that the whole structure is smooth and has no sharp part, tissues such as blood vessels are prevented from being scratched, and the tissues such as the blood vessels are protected to the greatest extent.

In a preferred embodiment, as shown in fig. 1-6, the straight section 22 and the bent section 21 may be integrally formed, for example, the straight section 22 and the bent section 21 may be formed into an integral structure by a mold, which not only has a simple structure and smooth lines, but also has an elegant appearance.

In a preferred embodiment, as shown in fig. 1 to 4, the first portion 10 and the second portion 20 may be integrally formed on the basis that the straight section 22 and the bent section 21 are integrally formed. Further has simple integral structure, smooth and fluent lines and beautiful and elegant appearance.

The drag hook can help to obtain a finer and perfectly designed drag hook, and a better dragging effect is achieved.
