Description

Technical Field

[0001] The utility model belongs to the technical field of medical instruments, and in particular relates to a pair of vertical pliers for surgical operations. Background Art

[0002] Surgical scissors are a commonly used medical instrument in clinical surgery, mainly used to cut rough and soft tissues such as skin or muscle; they can also be used to separate tissues, that is, the tip of the scissors is inserted into the tissue gap to separate connective tissue without large blood vessels, etc.; according to their structural characteristics, there are pointed, blunt, straight, curved, long and short types; according to their use, they are divided into tissue scissors and thread scissors; tissue scissors are mostly curved scissors, sharp and fine, used for dissecting, cutting or separating tissues; usually straight scissors are used for superficial surgical operations, and curved scissors are used for deep surgical operations; thread scissors are mostly straight scissors, which are divided into thread cutting scissors and suture removing scissors. The former is used to cut sutures, dressings, drainage tubes, etc., and the latter is used to remove sutures; the difference between thread scissors and tissue scissors is that the blade of tissue scissors is sharp and thin, while the blade of thread scissors is blunt and thick; therefore, you must never replace thread scissors with tissue scissors for the sake of convenience and speed, so as to damage the blade and cause waste; suture removing scissors are straight scissors with one blunt and one straight tip, used to remove sutures.

[0003] Existing surgical procedures often require cutting Kirschner wires to prevent them from being exposed outside the wound surface. However, conventional surgical scissors are usually designed with the cutting blades parallel to the scissors handles, and the Kirschner wires are cut horizontally during surgery. This requires the doctor to make a larger and deeper incision during the operation to have a clearer field of view. In addition, when two adjacent Kirschner wires need to be cut, the horizontal cutting method may increase the risk of accidental cutting or interference, because the surgical scissors may touch non-target Kirschner wires during operation. Moreover, traditional surgical scissors have no stable force point during cutting, making it difficult to ensure stability during cutting, which can easily result in uneven cutting surfaces or residual parts, affecting the surgical effect. Based on this, a vertical surgical scissors is proposed. Utility Model Content

[0004] The purpose of the present invention is to provide a vertical surgical pliers with a simple structure and reasonable design in order to solve the above problems.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0006] A vertical surgical pliers comprises two sets of handles and a cutting head, wherein the handles are fixedly connected to the cutting head, and the two sets of handles and cutting heads are connected via a connecting shaft.

[0021] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Example

[0023] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, a vertical surgical pliers comprises two sets of handles 1 and a blade 2, wherein the handle 1 is fixedly connected to the blade 2, and the two sets of handles 1 and the blade 2 are connected by a connecting shaft 4, and the two sets of handles 1 and the blade 2 can rotate at the connecting shaft 4. The two sets of handles 1 and the blade 2 connected by the connecting shaft 4 are in a "Y" shape as a whole. The "Y" shape design of the overall pliers ensures that the blade 202 can be completely closed when force is applied. When the blade 2 is closed, the upper end of the handle 1 is at an angle of about 30 degrees. The blade 202 comprises a handle 201 and a blade 202. The blade 202 is mounted on the end of the handle 201 through a fixing assembly, and the blade 20 2 is perpendicular to the knife handle 201. When shearing, since the blade 202 is perpendicular to the knife handle 201 and the bottom blade 202 is shorter, the knife handle 201 can be inserted between the two Kirschner wires even when two Kirschner wires are adjacent to each other, thereby avoiding accidental shearing and interference and improving the safety of the operation. The blade 202 is set to be sloped. The sloped blade 202 design increases the overall strength of the blade 202 while also ensuring the sharpness of cutting. The knife handle 1 includes a knife rod 101 and a handle 102. The handle 102 is fixedly connected to the side wall of the knife rod 101. The knife rod 101 and the handle 102 are both set to be arc-shaped.

[0024] When shearing the Kirschner wire, the knife rod 101 and the handle 102 are held to open the knife head 2 so that the blade 202 is open. The opened blades 202 are then placed on both sides of the Kirschner wire so that the blades 202 are in close contact with the wound surface. The knife rod 101 and the handle 102 are then held inward to close the knife head 2, and the Kirschner wire is vertically sheared by the blade 202. The vertical shearing design ensures that the area of ​​the cutter that actually penetrates the wound is only the smaller blade 202 at the bottom. There is no need to open the wound too large, which increases the convenience during the operation. The vertical shearing method ensures that the blade 202 can be in close contact with the wound surface while exerting force, ensuring that the sheared surface is neat and residue-free, thereby improving the surgical effect.

[0025] The effect of shearing Kirschner wires in a small area with almost no exposed part is achieved. The blade 202 is designed to be perpendicular to the handle 201, so that the area of ​​the cutters actually penetrating into the wound is only the smaller blade 202 at the bottom. This makes it possible to accurately shear off the target Kirschner wire when processing adjacent Kirschner wires without interference from non-target Kirschner wires, and at the same time increases the utilization rate of the blade 202.

[0026] like Figure 4 and Figure 5 As shown, the fixing assembly includes a slide groove 302, a fixing rod 303 is slidably connected in the slide groove 302, and a push-pull plate 308 is fixedly connected to the end of the fixing rod 303. The push-pull plate 308 is slidably connected in the slide groove 302, and a fixing spring 304 is fixedly connected to the side of the push-pull plate 308 away from the fixing rod 303. A fixing groove 307 is provided in the knife handle 201, and the fixing spring 304 is fixedly connected in the slide groove 302. The fixing groove 307 is tightly matched with the fixing rod 303. The fixing assembly also includes an insertion rod 301 fixedly connected to the end of the blade 202 close to the knife handle 201, a groove 305 is provided on the insertion rod 301, and a slot 306 is provided on the side of the knife handle 201 close to the blade 202. The fixing rod 303 passes through the groove 305 and is tightly matched with the groove 305, and the slot 306 is tightly matched with the insertion rod 301.

[0027] When the blade 202 is rolled or its sharpness is reduced, it needs to be replaced or sharpened. At this time, the push-pull plate 308 is manually buckled to move the push-pull plate 308 in the direction of the fixed spring 304, squeezing the fixed spring 304, thereby pulling the fixed rod 303 out of the fixed groove 307 and the groove 305, and then the blade 202 can be pulled outward, so that the insertion rod 301 is pulled out of the slot 306, and the blade 202 can be replaced or sharpened. When reinstalling, the push-pull plate 308 is manually buckled to move the push-pull plate 308 in the direction of the fixed spring 304, squeezing the fixed spring 304, and then pulling the fixed rod 303 out of the fixed groove 307 and the groove 305. Move in the direction of the fixing spring 304, squeeze the fixing spring 304, and then the fixing rod 303 is pulled out of the fixing groove 307 and reaches the side of the slot 306 close to the slide groove 302. Then, the insertion rod 301 on the blade 202 can be inserted into the slot 306. After insertion, the push-pull plate 308 can be released so that the push-pull plate 308, under the action of the squeezed fixing spring 304, pushes the fixing rod 303 through the groove 305 into the fixing groove 307, thus completing the fixation of the blade 202.

[0028] The blade 202 can be quickly disassembled and assembled, making it convenient to repair and replace the blade 202 and preventing the need to replace the entire pliers when the blade 202 is damaged, thereby extending the service life of the pliers except the blade 202 and saving resources.

[0029] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
