Description

Double-head surgical forceps

Technical Field

The utility model relates to a double-end field of operating forceps, in particular to a double-end operating forceps.

Background

As for the surgical forceps, it is known that a plurality of forceps are used in the operation, the forceps have different sizes and functions, and the forceps are commonly used for clamping tissues and shearing necrotic tissues, so that the forceps need to be replaced back and forth in the use, and a special person delivers the forceps. However, the common surgical forceps are more in use, the back-and-forth transmission is troublesome, the situation that a nurse takes the surgical forceps by mistake is easy to occur, the forceps heads can be replaced in the market, the back-and-forth installation is troublesome, the practicability is not strong, and therefore the surgical forceps are needed to be replaced by the forceps heads, and the use is convenient.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a double-end operation pincers to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the double-headed surgical forceps comprise two forceps arms which are hinged, finger rings are fixed at the tail ends of the forceps arms, and the other ends of the forceps arms are clamping ends;

the two clamping ends are arc-shaped with opposite openings, the inner sides of the tail ends of the two clamping ends are rotatably connected with a binding clip through a pin shaft, the binding clip is provided with a first binding clip and a second binding clip which are positioned at two ends in different directions, and the clamping ends are provided with a clamp and a mechanism which can automatically clamp and fix after the binding clip is turned over by one hundred eighty degrees.

Preferably, the card and the mechanism include the locking rod of pegging graft in two hold ends mutually the back of the body one end of carrying on the back, and the locking rod is close to one side of ring, the outer end of locking rod is fixed with draws the piece, and draws between piece and the hold end through cup jointing the spring coupling on the locking rod, set up about two draw-in grooves that correspond with the locking rod of round pin shaft symmetry on the binding clip, and the draw-in groove is the arc that makes things convenient for sliding in and roll-off behind the locking rod atress, the front end of binding clip is to the arc face of sliding in the draw-in groove after the one end of being close to the hold end is convenient for the locking rod.

Preferably, the upper end of the clamping groove is in arc transition with the end face corresponding to the clamping end.

Preferably, the first jaw face is a clamping face provided with a convex pattern.

Preferably, the second jaw face is a shearing face with a blade.

Compared with the prior art, the beneficial effects of the utility model are that:

1. when the forceps are used, the stop rod clamps the clamping groove under the action of the spring, and the forceps head is prevented from rotating around the pin shaft randomly under the tension of the spring, so that the operation work is performed;

2. the first clamp face is a clamping face and can play a clamping role, the second clamp face is a shearing face and has a shearing function, so that when the other clamp face needs to be replaced, the outer end of the clamp head is directly pulled by a hand with gloves to enable the clamp head to rotate around the pin shaft, the arc-shaped clamping groove extrudes the stop rod, the elastic force of the spring is overcome, the stop rod slides out of the clamping groove, and then the other end of the clamp head extrudes the stop rod to enable the stop rod to slide into the clamping groove, so that the fixing is carried out;

just accomplished the change of two kinds of pincers faces here, for direct plug change, the change of here direct upset, it is more convenient time-saving, more have the practicality, avoided making a round trip to change the operation pincers, also avoided the nurse to take the problem of wrong operation pincers, improved operation efficiency.

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.
