In order to solve the problems in the background technology, the utility model provides the following technical scheme: medical tweezers

Example 1

Comprising a forceps body 1, the forceps body 1 comprises a first forceps arm 11 and a second forceps arm 12 which are fixedly connected with each other, thereby forming medical forceps commonly used in the market.

In order to increase the area of hand pressing, the outer parts of the first forceps arm 11 and the second forceps arm 12 are provided with expansion areas 13.

Specifically, as follows, the extension plate 2 is fixedly connected to the outside of the first forceps arm 11, the extension plate 2 and the first forceps arm 11 can be integrally formed, a first mounting opening 21 is formed in the extension plate 2, a rotating block 4 is rotationally arranged in the first mounting opening 21, an arc-shaped inserting tongue 42 is fixedly arranged at the bottom end of the rotating block 4, and the arc-shaped inserting tongue 42 is used for being inserted into the second mounting opening 31 when the first forceps arm 11 and the second forceps arm 12 are pressed.

Therefore, a support plate 3 is also fixedly arranged outside the second forceps arm 12, the support plate 3 and the second forceps arm 12 are integrally formed, and a second mounting opening 31 is arranged in the support plate 3 and mainly used for receiving the inserted arc-shaped insert tongue 42.

In order to fix the position of the arc-shaped insert tongue 42, the utility model also provides a limiting component, and the limiting component can limit the arc-shaped insert tongue 42 not to be pulled out when the arc-shaped insert tongue 42 is inserted into the second mounting opening 31.

The specific design is as follows, spacing subassembly includes the fixed mounting at the outside multiunit skewed tooth 43 of arc insert tongue 42 and fixed mounting in the fixed block 32 of second installing port 31, and fixed mounting has the skewed block 33 outside of fixed block 32, and specific refining, skewed tooth 43 and skewed block 33 are hypotenuse triangle structure, so can let the roof of skewed tooth 43 closely contradict with the diapire of skewed block 33 when arc insert tongue 42 inserts in the second installing port 31 to spacing fixed is carried out the position of arc insert tongue 42, makes it can not extract in the second installing port 31.

In order to increase the adsorption effect, the bevel gear 43 is made of iron, the bevel block 33 is made of iron-absorbing stone, and the arrangement is that when the top wall of the bevel gear 43 is tightly abutted against the bottom wall of the bevel block 33, the limit fixing effect can be increased by the adsorption of the iron-absorbing stone to the bevel block 33, and the slipping-out is avoided.

In order to enable the arc-shaped insert tongue 42 to drive the bevel gear 43 to be automatically inserted into the bevel block 33, a fixed rod 44 is fixedly arranged outside the rotating block 4, a pressing plate 41 is fixedly connected to the top end of the rotating block 4 for convenient pressing, the fixed rod 44 is rotatably arranged in the first mounting port 21, a torsion spring 45 is sleeved outside the fixed rod 44, two ends of the torsion spring 45 are respectively clamped with the fixed block 32 and the inner wall of the first mounting port 21, and therefore, in an initial state, the rotating block 4 can have a counterclockwise rotation trend under the torsion of the torsion spring 45;

referring to fig. 3, in order to avoid the rotation of the rotation block 4 counterclockwise by a larger angle under the torsion of the torsion spring 45, a blocking lever 23 is fixedly connected in the first mounting opening 21, and the blocking lever 23 abuts against the outer wall of the pressing plate 41 to block the pressing plate 41 and simultaneously block the counterclockwise rotation of the rotation block 4.

The specific process is as follows, when the arc-shaped insert tongue 42 is inserted into the second mounting opening 31, then under the action of the torsion spring 45, the top wall of the helical tooth 43 tightly abuts against the bottom wall of the helical block 33, so that the position of the arc-shaped insert tongue 42 is limited and fixed, and the arc-shaped insert tongue cannot be pulled out from the second mounting opening 31.

Specific reference is made to the following operations

When the forceps main body 1 is taken to clamp the sterilized cotton ball or tissue, a doctor only needs to press the first forceps arm 11 and the second forceps arm 12 to move in opposite directions to clamp the sterilized cotton ball or tissue;

while clamping, the arc-shaped inserting tongue 42 is also inserted into the second mounting opening 31, and then under the action of the torsion spring 45, the top wall of the helical tooth 43 is tightly abutted against the bottom wall of the helical block 33, so that the position of the arc-shaped inserting tongue 42 is limited and fixed, and the arc-shaped inserting tongue cannot be pulled out from the second mounting opening 31;

therefore, the positions of the first forceps arm 11 and the second forceps arm 12 can be fixed and cannot be separated, so that a doctor does not need to hold the first forceps arm 11 and the second forceps arm 12 all the time, and can carry out subsequent operation only by taking the outer part of the forceps main body 1, and the hand force of the doctor is saved;

when it is desired to release the gripped object,

the pressing plate 41 is only pressed downwards by fingers, so that the pressing plate 41 drives the rotating block 4 to rotate clockwise by taking the fixed rod 44 as the center, and meanwhile, the torsion spring 45 is torsionally stressed, and referring to fig. 3, the rotating block 4 drives the arc-shaped inserting tongue 42 to rotate, so that the inclined teeth 43 do not collide with the inclined block 33, and then the first forceps arm 11 and the second forceps arm 12 lose restriction, so that the forceps can be opened, and the clamped object can be loosened.

Example two

The first difference between this embodiment and the first embodiment is that the limiting assembly of this embodiment includes a magnet fixedly installed outside the arc-shaped insert tongue 42 and fixedly installed in the second installation opening 31;

specifically, when the arc-shaped insert tongue 42 is inserted into the second mounting opening 31, it can be fixed and limited by mutual adsorption between the magnet outside the arc-shaped insert tongue 42 and the magnet in the second mounting opening 2.

Example III

In the first embodiment, a second magnet 46 is fixedly installed at the bottom end of the pressing plate 41, a first magnet 22 is fixedly installed in the second installation opening 31, and the first magnet 22 and the second magnet 46 are arranged in a homopolar repulsion manner, namely S-S or N-N;

specifically, the purpose of this arrangement is that if the bevel gear 43 is not in contact with the bevel block 33, the pressing plate 41 needs to be pressed downward;

in order to avoid the hand from striking the pressing plate 41 by mistake in the operation process, the arc-shaped inserting tongue 42 rotates, so that the first magnet 22 and the second magnet 46 are arranged in a homopolar repulsion mode, when the pressing plate 41 is pressed downwards to rotate, certain damping is provided, the damping (under the torque resistance of the torsion spring 45) can offset the force of the hand from striking by mistake, and the force of the hand from striking by mistake is generally smaller; the safety of the forceps body 1 is ensured.

The foregoing detailed description of the utility model has been presented for purposes of illustration and description, and it should be understood that the utility model is not limited to the particular embodiments disclosed, but is intended to cover all modifications, equivalents, alternatives, and improvements within the spirit and principles of the utility model.
