Description

TECHNICAL FIELD

[0001] The application relates to the technical field of surgical instruments, in particular to a double-eyelid non-scar surgical instrument. BACKGROUND

[0002] Double eyelid refers to a shallow groove in the skin above the eyelid margin. When the eyes are open, the skin below the groove moves up, and the skin above the groove relaxes and hangs down at the double-eyelid groove. Such double eyelid can make the eyes look larger and more stereoscopic, and the face more delicate, thereby improving the owner's self-confidence in appearance. For people with single eyelid, a double-eyelid non-scar plastic surgery can achieve the effect of double eyelid, which is a very effective and long-term surgical plastic surgery.

[0003] The double-eyelid non-scar surgical method generally includes the buried thread method and the suture method. During the double-eyelid surgery, a surgical knife is needed. In order to prevent cross infection, most plastic and cosmetic hospitals use disposable blades and knife handles matched with the disposable blades. The blade and the handle are connected, so that the blade can be replaced.

[0004] The prior art discloses a double-eyelid non-scar plastic device including a handle, a mounting head and a blade mounted on the mounting head. A length adjusting mechanism is arranged in the handle. An angle adjusting mechanism is arranged between the mounting head and the handle. The length adjusting mechanism includes a transmission rod and a threaded sleeve rod. One end of the transmission rod is movably arranged in the handle and extends out of one end of the handle. One end of the transmission rod is threadedly connected with the threaded sleeve rod. The other end of the transmission rod is fixedly connected with the angle adjusting mechanism. A rotating rod is rotatably arranged at one end of the handle away from the mounting head. The rotating rod is fixedly connected with the threaded sleeve rod.

[0005] Although the plastic device in the prior art can adjust the length of the blade, the rotating rod serving as the drive is arranged at the rear end of the handle. When the length is adjusted, one hand needs to hold the handle, and the other hand needs to rotate the rotating rod to adjust. In summary, both hands need to be coordinated to adjust, which is inconvenient for adjustment during the operation. Therefore, a double-eyelid non-scar plastic device for conveniently adjusting the length of the blade head with one hand is needed. CONTENT OF THE UTILITY MODEL

DETAILED DESCRIPTION

[0026] The present application will be further described in detail below with specific embodiments in combination with the accompanying drawings. EMBODIMENT

[0027] As shown in Figure 1 , a double-fold eyelid traceless plastic device suitable for suture method in double-fold eyelid traceless surgery, specifically comprising a cutter head 1 installed at the front end of the handle, the handle comprising a front section of handle 2, a middle section of handle 3, a rear section of handle 4, a first connecting rod 5, and a driving ring 6, the front section of handle 2 is fixedly connected with the middle section of handle 3, the middle section of handle 3 is spaced apart from the rear section of handle 4 and connected through the first connecting rod 5 located at the periphery of the handle, the driving ring 6 is rotationally installed between the middle section of handle 3 and the rear section of handle 4, and the cutter head 1 is inserted with the front end of the front section of handle 2.

[0028] As shown in Figure 2 , a threaded rod 11 is threadedly sleeved at the center of the driving ring 6, the front end of the threaded rod 11 extends into the middle section of handle 3 and is installed with a sliding rod 7, the front end of the sliding rod 7 extends into the front section of handle 2 and is in close contact with the inner wall of the front section of handle 2, the sliding rod 7 is guided to do linear motion through the front section of handle 2, the rear end of the cutter head 1 is installed with a second connecting rod 10, the rear end of the second connecting rod 10 is inserted into the front section of handle 2 and is threadedly connected with the front end of the sliding rod 7.

[0029] The middle section of handle 3 and the rear section of handle 4 are connected through the first connecting rod 5, so that the driving ring 6 can rotate independently between the middle section of handle 3 and the rear section of handle 4, and the linear guidance of the sliding rod 7 by the front section of handle 2 makes the threaded rod 11 unable to rotate, in combination with the rotation of the driving ring 6, so that when the driving ring 6 rotates, it will drive the threaded rod 11 to move along the handle axis, and in turn drive the sliding rod 7 and the cutter head 1 to move, so as to adjust the length of the cutter head 1, and the design that the driving ring 6 is located between the middle section of handle 3 and the rear section of handle 4 makes the main surgeon rotate the driving ring 6 by the cooperation of the thumb and the index finger, so as to facilitate the main surgeon to adjust and operate with one hand during the operation, without the need for two-handed adjustment, which improves the actual operation convenience and is conducive to the performance of double-fold eyelid surgery.

[0030] Further, as shown in Figure 1As shown, the distance between the driving ring 6 and the front end face of the shank front section 2 is less than the length of the shank rear section 4, so that the driving ring 6 is located at the front middle position of the shank, when the surgeon holds the shank, the palm holds the shank rear section 4, and the thumb and the index finger are placed on the shank middle section 3, when the length of the tool bit 1 needs to be adjusted, the surgeon only needs to rotate the driving ring 6 by the thumb and the index finger, so as to adjust the length of the tool bit 1.

[0031] Further, as shown in Figure 2 The inner wall of the shank front section 2 is provided with a plurality of limiting grooves 8 distributed along the length direction thereof, the limiting grooves 8 are uniformly arranged along the circumferential direction of the inner wall of the shank front section 2, the outer wall of one end of the sliding rod 7 close to the threaded rod 11 is provided with a plurality of limiting sliding blocks 9 matched with the limiting grooves 8, the limiting sliding blocks 9 are one-to-one corresponding to the limiting grooves 8, and the sliding rod 7 is slidably inserted into the limiting grooves 8 through the limiting sliding blocks 9, so that the sliding rod 7 can move axially in the shank front section 2 but cannot rotate, thereby facilitating the linear motion of the sliding rod 7, the second connecting rod 10 and the threaded rod 11, and further realizing the telescopic adjustment of the tool bit 1.

[0032] Further, as shown in Figure 1 and Figure 2 The first connecting rod 5 is U-shaped and the opening faces upward, the first connecting rod 5 is arranged on the same side of the shank middle section 3 and the shank rear section 4, and the two ends of the first connecting rod 5 are fixedly connected with the outer walls of the shank middle section 3 and the shank rear section 4, respectively, which is convenient for the surgeon to hold the first connecting rod 5 by the index finger when cutting the skin, so as to improve the gripping force of the shank and further improve the operation precision.

[0033] Further, the two side end faces of the driving ring 6 are provided with connecting rings, and the two connecting rings are rotatably connected with the rear end of the shank middle section 3 and the front end of the shank rear section 4, respectively, which facilitates the rotation of the driving ring 6 between the shank middle section 3 and the shank rear section 4.

[0034] Further, the shank front section 2, the shank rear section 4 and the driving ring 6 are all hollow cylindrical, the outer diameters of the shank rear section 4 and the driving ring 6 are consistent and larger than that of the shank front section 2, and the shank middle section 3 is hollow and in the shape of a circular truncated cone, the outer diameter of the shank middle section 3 gradually increases from the shank front section 2 to the driving ring 6, and the two end faces of the shank middle section 3 are coincided with the shank front section 2 and the driving ring 6, respectively, which makes the shank front end thin, and the inclined surface of the circular truncated cone of the shank middle section 3 is helpful for the surgeon to place the thumb and the index finger, conforms to the ergonomic design, and is convenient for operation. Embodiment
