Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1 to 4, the present invention provides a double-headed surgical clamp, which comprises: the utility model provides a double-end operation pincers, includes tong arm 1, tong arm 1 establishes to two of articulated connection, connects through the axle is articulated, for prior art, and the end of tong arm 1 is fixed with ring 11, and the other end of tong arm 1 is exposed core 12, also is the operation end, carries out the operation end.
The two clamping ends 12 are arc-shaped with opposite openings, the inner sides of the tail ends of the two clamping ends 12 are rotatably connected with a binding clip 2 through a pin shaft, the binding clip 2 is provided with a first binding clip 21 and a second binding clip 22 which are positioned at the two ends in different directions, and the clamping ends 12 are provided with a clamp and a mechanism which can automatically clamp and fix after the binding clip 2 turns over one hundred eighty degrees, the clamp and the mechanism comprise stop rods 23 which are inserted at the opposite ends of the two clamping ends 12, and the stop rod 23 is close to one side of the finger ring 11, the outer end of the stop rod 23 is fixed with a pull block 24, the pulling block 24 is connected with the clamping end 12 through a spring 25 sleeved on the stop rod 23, two clamping grooves 26 which are symmetrical relative to the pin shaft and correspond to the stop rod 23 are arranged on the binding clip 2, and the locking groove 26 is in a circular arc shape which is convenient for the stop rod 23 to slide in and out after being stressed, and is similar to a part of a spherical surface, so that the stop rod 23 can slide out after being stressed around the pin shaft.
The front end of binding clip 2 is connected to the arc surface that is close to the one end of exposed core 12 and is made things convenient for stopper 23 to slide into draw-in groove 26 after the extrusion, the side is the curved surface just in other words around, when stopper 23 rotated like this, shift up along the arc surface, overcome spring 25's elasticity, the terminal surface circular arc transition that upper end and exposed core 12 of draw-in groove 26 correspond makes things convenient for behind stopper 23 atress roll-off, binding clip face 21 is the clamping face that is provided with the burr, can press from both sides tight tissue dead skin like this, binding clip face two 22 is the shear plane that has the cutting edge, can cut necrotic tissue, thereby make binding clip 2 have the function of centre gripping and shearing.
The working principle is as follows: when the pliers are used, the stop rod 23 clamps the clamping groove 26 under the action of the spring 25, the pliers head 2 is prevented from rotating around a pin shaft at will under the tension of the spring 25, so that operation work is performed, the first pliers face 21 is a clamping face and can play a role in clamping, the second pliers face 22 is a shearing face and has a shearing function, and therefore when another pliers face needs to be replaced, the outer end of the pliers head 2 is directly pulled by a hand with gloves, the pliers head 2 is enabled to rotate around the pin shaft, the arc-shaped clamping groove 26 extrudes the stop rod 23, the elastic force of the spring 25 is overcome, the stop rod 23 slides into the clamping groove 26 after the other end of the pliers head 2 extrudes the stop rod 23, and accordingly fixation is achieved, and replacement of the two pliers faces is achieved.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
