The forceps head 4 for medical instruments of the present embodiment is particularly a pair of nucleus pulposus forceps, which is used as an auxiliary instrument in orthopedic surgery, and is mainly used for taking out putrid bones and trimming bone tissues in orthopedic surgeries such as nuclectomy and the like.

The utility model discloses in, the operator passes through the utility model discloses after getting the nucleus pulposus, the movable pincers handle 21 outwards opens for better restriction, and two relative articulated pieces 611 of one end fixedly connected with of round pin axle 5 are being kept away from to fixed pincers handle 11, are equipped with threaded rod 62 between two articulated pieces 611, wear to be equipped with bolt 612 on one of them articulated piece 611, and bolt 612 wears to establish threaded rod 62 and with another articulated piece 611 threaded connection. Because activity pincers handle 21 is at the rotation in-process, can produce a rotation volume between threaded rod 62 and the activity pincers handle 21 to offer on activity pincers handle 21 and supply threaded rod 62 pivoted waist type groove 64, the other end of threaded rod 62 wears out activity pincers handle 21 and threaded connection has cylindrical latch segment 63, passes through when the operator the utility model discloses press from both sides and live behind the nucleus pulposus, the operator can rotate latch segment 63 towards the direction of activity pincers handle 21, and it is inconsistent with activity pincers handle 21 until latch segment 63, and latch segment 63 has reduced the outside open possibility of activity pincers handle 21 this moment, thereby reduces the possibility that leads to the nucleus pulposus to drop, makes fixed pincers handle 11 and activity pincers handle 21 remain stable clamping state, has improved the security of operation.

The utility model discloses in, through twisting the position of the adjustable blade 72 of nut 74, when blade 72 stretches out sword groove 71, the utility model discloses can use as the scissors, when blade 72 is located sword groove 71, the utility model discloses can use as normal medical pincers, its is rational in infrastructure, and the practicality is strong, strengthens the function of ordinary medical pincers.

The utility model discloses in, make the structure that separately constitutes by pincers handle and binding clip 4 through making medical pincers, when medical pincers take place binding clip 4 rupture, wearing and tearing, deformation etc. and lead to its condition that can not use, can take out binding clip 4 part to change newly, thereby can make full use of the not fragile characteristics of pincers handle, furthest prolongs the life of medical pincers, thereby can save material, reduce use cost.

Referring to fig. 2-3, specifically, the rear end of the fixed forceps handle 11 is further provided with a first rack 12 extending to the movable forceps handle 21, the rear end of the movable forceps handle 21 is provided with a second rack 22 corresponding to the first rack 12, the second rack 22 is engaged with the first rack 12, and a hinge joint between the fixed forceps handle 11 and the movable forceps handle 21 is provided with a gap for separating the first rack 12 from the second rack 22.

In this embodiment, the height of the saw teeth 23 on the rack is not more than 2 mm, and since the movable clamp handle 21 and the fixed clamp handle 11 have a lever effect by taking the pin 5 as a center, the hinged position of the movable clamp handle 21 and the fixed clamp handle 11 only needs to be provided with a gap of 0.1 mm-0.2 mm. When an operator clamps the nucleus pulposus through the utility model, the rack on the movable clamp handle 21 is meshed with the rack on the fixed clamp handle 11, so that the possibility that the movable clamp handle 21 is opened outwards is reduced, and the possibility of causing the nucleus pulposus to fall off is reduced; when the operator takes out from the human body the utility model discloses afterwards, the operator stirs movable pincers handle 21 downwards for two rack separation, thereby the fixed pincers handle 11 is kept away from under the elastic force that opens elasticity plectrum 3 to the activity pincers handle 21 of being convenient for, convenient and fast makes nucleus pulposus follow the utility model discloses on fall down.

Referring to fig. 2, specifically, the hinge 61 includes two opposite hinge blocks 611 disposed on the fixed clamp handle 11, the threaded rod 62 is disposed between the two hinge blocks 611, a bolt 612 is connected between the two hinge blocks 611, and the bolt 612 is disposed in the threaded rod 62 in a penetrating manner.

Through the scheme, the threaded rod 62 is hinged between the two hinge blocks 611 through the bolts 612, and when the threaded rod 62 is damaged, an operator can unscrew the bolts 612, so that the threaded rod 62 can be taken out, and the operator can replace the threaded rod 62 conveniently.

Specifically, the circumferential surface of the locking block 63 is provided with a plurality of ribs 631.

The ribs 631 formed on the circumference of the locking block 63 increase the friction between the hand of the operator and the locking block 63, thereby reducing the possibility of slipping of the hand of the operator during rotation of the locking block 63.

Referring to fig. 1-2, specifically, the fixed handle 11 and the movable handle 21 are both provided with a plurality of grooves 13 for easy holding.

Recess 13 makes the operator grip the utility model discloses the time is comparatively comfortable, has also reduced the possibility that the operator hand skidded when gripping, has improved the security of operation.

Referring to fig. 5, specifically, the connecting end of the binding clip 4 is provided with a stud 43, the connecting end of the fixed clamp handle 11 and the movable clamp handle 21 is provided with a screw hole corresponding to the stud 43, the stud 43 is screwed with the screw hole, and the binding clip 4 is fixed on the fixed clamp handle 11 and the movable clamp handle 21.

Make the standard component with the pincers handle together with its screw, binding clip 4 together with its double-screw bolt 43 during manufacturing, in case take place binding clip 4 rupture, wearing and tearing, deformation etc. and lead to the utility model discloses during the condition that can not use, can unscrew binding clip 4, then change new binding clip 4 and screw and can reuse on the pincers handle.

Referring to fig. 1, specifically, the fixed connecting rod 1 is provided with scale lines 81, and the fixed connecting rod 1 is further provided with a first warning coating 82 and a second warning coating 83.

In this embodiment, the distance from the front end of the first warning coating 82 to the front end of the fixed binding clip 4 is 30 mm, and the distance from the rear end of the first warning coating 82 to the front end of the fixed binding clip 4 is 40 mm; the front end of the second warning coat 83 is spaced from the front end of the fixed jaw 4 by 50 mm, and the rear end of the second warning coat 83 is spaced from the front end of the fixed jaw 4 by 60 mm.

The scale and the warning coating are arranged, so that an operator can easily judge the entering depth of the medical forceps, and the operator can accurately determine the maximum entering depth of the medical forceps, thereby reducing the risk of damaging the great vessels of abdominal viscera.

Specifically, the first warning coating 82 is yellow, and the second warning coating 83 is red.

The yellow and red colors are striking, which is beneficial to reminding the operator to pay attention to the depth of entry.

The above embodiments are only for describing the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements made by the technical solution of the present invention by those skilled in the art are all within the scope of the present invention as defined by the claims.
