Description

Scissors special for tracheal cricoid cartilage

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to special scissors of trachea cricoid cartilage.

Background

Malignant tumors of the oral cavity, such as tongue cancer, mouth bottom cancer and the like, postoperative swelling of the operated area, and swollen repaired flap and the like often require a tracheotomy. At present, the tracheal cartilage is cut off by tissue scissors in clinical practice, as shown in fig. 1, which is a schematic structural diagram of the trachea, including the main body part of the trachea and the tracheal cartilage. At present, the main method of tracheotomy is to transversely cut the trachea between the tracheal cricoid cartilages in the first step after the tracheal cricoid cartilages are exposed, then cut the tracheal cricoid cartilages on both sides to form an inverted U-shaped cut, and place the cut into a tracheal cannula. However, the conventional tissue scissors have the following defects: 1. the angle of the scissor head is not ideal enough, and an ideal inverted U-shaped shape is difficult to cut in actual operation; 2. when the tracheal cartilage is cut off, the scissor head is hard tissue, so that the tracheal cartilage is not easy to fix and is easy to slide, the edge of the cut tracheal cartilage is irregular, a bone tip is formed, and the tracheal cannula air bag is cut.

Disclosure of Invention

An object of the utility model is to provide a convenient operation, skid-proof trachea cricoid cartilage special use is cut.

In order to achieve the purpose of the invention, the technical scheme adopted by the utility model is as follows: a pair of tracheal cricoid cartilage special scissors comprises a minimally invasive scissors main body, wherein the main body is composed of two scissor arms with middle sections hinged with each other; the front ends of the scissor arms are provided with elbows bent towards the same side, and a shearing area is formed between the elbows of the two scissor arms; the included angle between the elbow and the corresponding scissor arm is an obtuse angle; the cut side edge of the elbow on one side of the inner corner is provided with a groove for accommodating the tracheal ring cartilage.

Preferably, the groove is semicircular or semi-elliptical, and the width of the opening of the groove is 5-7 mm.

Preferably, the included angle between the elbow and the corresponding scissor arm is 130-140 degrees.

Preferably, the angle between the elbow and the corresponding scissor arm is 135 °.

Preferably, the elbow and the corresponding scissor arm are of an integral structure.

Preferably, the elbow is detachably connected with the corresponding scissor arm.

Preferably, the rear end of the scissor arm is provided with a finger ring.

The beneficial effects of the utility model are that the appearance is concentrated, convenient operation, can stabilize quick seting up the incision of falling the U-shaped on the trachea. Particularly, utilize conventional tissue earlier to cut along transversely cutting open the clearance between the trachea ring cartilage during the use, then recycle the utility model discloses cut the trachea ring cartilage of both sides, and then form the incision of falling the U-shaped. Compare with the straight tissue scissors of tradition, because the utility model discloses the tip of scissors arm is provided with the elbow, can not appear poor hand condition when going to trachea ring cartilage and cutting, operating angle is more reasonable. Meanwhile, the groove arranged on the shearing side edge of the elbow can be just clamped on the tracheal ring cartilage main body, so that certain positioning is formed, and the phenomena of slipping and position deviation in the shearing process are prevented. And then the smoothness of shearing the fracture and the regularity of incision have effectually been guaranteed. The tracheal cannula is erected conveniently, and the balloon of the tracheal cannula is prevented from being scratched. Of course, in order to ensure that the tracheal cartilage on the left and right sides can be cut, the utility model discloses dispose two usually, the crisscross opposite direction of two scissors arms of two special scissors, recess one left side on two special scissors is right.

Detailed Description

The scissors special for tracheal cartilage rings shown in the figures 1 to 5 are the same as the traditional tissue scissors and comprise a minimally invasive scissors main body, wherein the main body is composed of two scissor arms 1, the middle sections of which are hinged with each other. Typically, both scissor arms 1 are made of medical grade stainless steel material, or medical grade high molecular plastics. The rear end of the scissors arm 1 can be in a rod type or a ring type, as shown in fig. 1, namely, the scissors arm is in a ring type, namely, the rear end of the scissors arm 1 is provided with finger rings 4 for being sleeved with fingers, when in use, one finger ring 4 is penetrated through the thumb, and the other finger ring 4 is penetrated through the middle finger or the index finger.

The front end of the shear arm 1 is provided with an elbow 2 which is bent towards the same side, and a shearing area is formed between the elbows 2 of the two shear arms 1. When in use, the section where the shearing area is positioned is used for shearing the tracheal ring cartilage. The included angle between the elbow 2 and the corresponding scissor arm 1 is an obtuse angle, so that the operation angle is more suitable, and the situation of poor hand can not occur. Typically the angle B between said elbow 2 and the corresponding scissor arm 1 is 130-140 deg., with 135 deg. being most preferred. The elbow 2 and the corresponding scissor arm 1 are usually of an integral structure, that is to say, the elbow 2 is formed by bending the end part of the scissor arm 1 directly, and the two are integrated. Of course, detachable connections with a split structure are also possible, such as snap-fit, tongue-and-groove, small screw connections, etc., and even adhesive bonding.

As shown in fig. 2 and 3, the cut side edge of the elbow 2 on the side of the inside corner is provided with a groove 3 for receiving the tracheal ring cartilage. The shape and the size of the groove 3 are equivalent to those of the tracheal ring cartilage, the groove is generally semicircular or semielliptical, and the width of the opening of the groove 3 is 5-7 mm.

During the use earlier utilize conventional sharp blade along transversely cutting the clearance between the trachea cricoid, then recycle the utility model discloses cut the trachea cricoid of both sides, and then form the incision of falling the U-shaped. Compare with the straight tissue scissors of tradition, because the utility model discloses the tip of scissors arm 1 is provided with elbow 2, can not appear poor hand condition when going to tracheal ring cartilage and cutting, operating angle is more reasonable. Meanwhile, the groove 3 arranged on the shearing side edge of the elbow 2 can be just clamped on the tracheal ring cartilage main body, so that certain positioning is formed, and the phenomena of slipping and position deviation in the shearing process are prevented. And then the smoothness of shearing the fracture and the regularity of incision have effectually been guaranteed. The tracheal cannula is erected conveniently, and the balloon of the tracheal cannula is prevented from being scratched. Of course, in order to ensure that the tracheal cartilage on the left and right sides can be cut, as shown in fig. 2 and 3, the utility model discloses two are usually configured, the crisscross opposite direction of two scissors arms of two special scissors, and the recess one on two special scissors is left one right. In the figure, the recesses 3 are located on the lower scissor arm 1, while the lower scissor arm 1 is located on the front side and the rear side of the upper scissor arm 1, respectively, in order to accommodate the tracheal cartilages on the left and right during cutting.
