In the attached drawing, 1-a first jaw, 2-a second jaw, 12-a connecting ring, 3-antiskid teeth, 301-a first section of teeth, 302-a second section of teeth, 303-a third section of teeth, 4-a pin shaft and 5-a shaft seat.

The specific implementation mode is as follows:

in view of this, the present invention provides a micro-type anti-slip forceps head for surgical forceps, which is described below with reference to the attached drawings.

Referring to fig. 1-4, the present invention provides a micro-surgical forceps anti-slip head, which comprises: the device comprises a first jaw 1, a second jaw 2 and anti-skid teeth 3; the first jaw 1 is hinged with the second jaw 2, the first jaw 1 is symmetrical to the second jaw 2, the inner side of the first jaw 1 and the inner side of the second jaw 2 are clamping surfaces which can be overlapped with each other, anti-skid teeth 3 are arranged on the clamping surfaces, and the anti-skid teeth 3 are arranged from the front end of the jaw to the root of the jaw from dense to sparse.

Particularly, the anti-skid binding clip of the micro-operation clamp of the utility model can be used not only in the hand-held operation clamp directly used by doctors, but also in the operation clamp mainly used in the microsurgery; the size interval of the anti-skid lines of the existing surgical forceps is usually 0.5mm, the line height is also more than 0.5mm, and the adopted lines are all single-specification lines, so that the anti-skid effect is not good, and blood vessel tissues are easily damaged. The utility model provides an antiskid binding clip, grip segment's length is only 1.7mm to from front end to root on 1.7mm keep silent, with 3 designs of antiskid tooth to the structure of following fine and close gradually to wide dredging, thereby reach not the slippage, do not harm human tissue's such as blood vessel effect.

The utility model provides a miniature surgical clamp antiskid binding clip, the jaw adopts the multistage to be sawtooth antiskid structure, the inboard of two jaws is the clamping face that can coincide each other, is provided with antiskid tooth 3 on two clamping faces, the tooth interval of antiskid tooth 3 from the jaw front end to the jaw root is first section tooth 301, second section tooth 302 and third section tooth 303 in proper order; the tooth spacing of the second section of teeth 302 is larger than that of the first section of teeth 301 and smaller than that of the third section of teeth 303, the tooth height of the second section of teeth 302 is larger than that of the first section of teeth 301 and smaller than that of the third section of teeth 303, and the tooth height is the distance from the tooth tip to the tooth root.

The pressure of the first jaw 1 and the second jaw 2 is higher towards the front end position and lower towards the root part; therefore, the anti-skid tooth 3 with the structure is designed, in the clamping process, the height of the third section of teeth 303 is higher than that of the second section of teeth 302 and the first section of teeth 301 at the front end, when in clamping, the first section of teeth 301 of the first jaw 1 and the second jaw 2 cannot be tightly pressed, the pressure of the first section of teeth 301 at the front end on human tissues such as blood vessels can be reduced, the anti-skid grains of the first section of teeth 301 are most compact, and the blood vessels are not easily damaged under the condition of avoiding the slippage of the tissues; when reaching the second section of teeth 302 and the third section of teeth 303, the pressure and the friction force to blood vessels and tissues need to be increased, so that the tooth height and the tooth space are increased; the utility model provides a miniature operation clamp antiskid binding clip is no matter be used the operation clamp or the clamp of using in the micro-operation, can both effectively prevent human tissue's such as blood vessel slippage, can not harm tissues such as blood vessel simultaneously.

When the forceps are applied to microsurgery, the first jaw 1 and the second jaw 2 are sharp-nose jaws, and the length from the front end of each jaw to the root of each jaw is 1.7mm. The tooth width of the anti-skid teeth 3 is 0.005mm, and the tooth width is the length occupied by one anti-skid tooth 3 in the direction from the front end of the jaw to the root of the jaw; the tooth length of the antiskid tooth 3 is consistent with the width of the clamping surface. The teeth spacing of the first stage of teeth 301 is 0.005mm, the teeth spacing of the second stage of teeth 302 is 0.008mm, and the teeth spacing of the third stage of teeth 303 is 0.01mm. The tooth height of the first section of teeth 301 is 0.005mm, the tooth height of the second section of teeth 302 is 0.008mm, and the tooth height of the third section of teeth 303 is 0.01mm.

The roots of the first jaw 1 and the second jaw 2 are respectively connected to respective connecting rings 12, the connecting rings and the side surfaces of the jaws are positioned on the same plane, a pin shaft 4 penetrates through the connecting rings 12 of the first jaw 1 and the second jaw 2, and two ends of the pin shaft 4 pass through mounting holes of the shaft seat 5; alternatively, the connection rings 12 of the first jaw 1 and the second jaw 2 are riveted by rivets. The way of mounting the first jaw 1 and the second jaw 2 is not limited herein, and it can be applied to various scenes according to the different sizes, so long as the hinging achieves the clamping action of the first jaw 1 and the second jaw 2.

This miniature surgical clip antiskid binding clip adopts the little sawtooth antiskid structure of multistage, degaussing treatment has been carried out simultaneously, its dimensional design can correspond not unidimensional suture needle, the centre gripping dynamics is less than general handheld clamp, be difficult for causing the displacement of suture needle, the slippage, warp, also can correspond not unidimensional microsurgery clamp, be difficult to cause the slippage of tissue, and can stretch into the narrow and small space that the staff can't touch, reach the antiskid and take off, prevent that vascular tissue is hindered by the clamp and cause the risk of inflammation and secondary damage, the adhesion of human tissue has been reduced.
