Based on the embodiments in the present invention, all other embodiments obtained by the skilled in the art without creative work belong to the protection scope of the present invention.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be implemented in other ways different from the specific details set forth herein, and one skilled in the art may similarly generalize the present invention without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.

As shown in fig. 1 to 3, an embodiment of the scalp forceps of the present disclosure includes two forceps handles 1 disposed in a crossing manner and rotatably connected via a rotating shaft to form a conventional forceps body structure, and a distance maintaining assembly capable of separating the two forceps handles 1 is disposed between the two forceps handles 1, and the distance maintaining assembly generally employs a spring assembly, such as a helical spring ring or an arc-shaped spring plate, and is configured to slow down the closing speed of the distraction section when the scalp forceps are withdrawn, and to avoid the occlusion, dislocation and reverse crossing of the distraction section.

In the scalp clamp, an opening section is formed at the front end of a clamp handle 1, the two opening sections are folded and can extend into a scalp clamp, a handheld section is formed at the rear end of the clamp handle 1, finger rings 11 are arranged on the inner sides of the two handheld sections, fingers extend into the finger rings 11, and medical staff outputs force to separate the two handheld sections, so that the two opening sections are opened to open an opening of the scalp clamp.

In this embodiment, the scalp clip further includes a link mechanism 2. The connecting rod mechanism 2 is arranged between the two handheld sections and comprises a first connecting rod 21 and a second connecting rod 22, opposite ends of the first connecting rod 21 and the second connecting rod 22 are rotatably connected through a connecting assembly and can be locked, an opposite end of the second connecting rod 22 is rotatably connected with the corresponding handheld section through a rotating shaft, and when the first connecting rod 21 and the second connecting rod 22 are located on the same straight line, the opening angle between the two spreading sections is the maximum allowable value. When the device is not used, the two expansion sections are close, and the first connecting rod 21 and the second connecting rod 22 are connected in an angle.

The scalp clip is characterized in that a link mechanism 2 capable of controlling the maximum value of the opening angle of the two spreading sections is arranged between the two clip handles 1, and the arrangement of the link mechanism 2 can prevent the scalp clip from being damaged due to the overlarge spreading angle of the scalp clip; on the other hand, after the scalp clip is spread by an overlarge angle, when the scalp clamps are loosened, the opening of the scalp clip is quickly closed due to large deformation energy storage of the scalp clamps, and the instantaneous force of the scalp clip on the body of a patient is large, so that the body is prevented from being damaged, and the wound healing of the patient is prevented from being influenced.

The connecting assembly comprises a screw 23, a fixing cap 24, a locking plate 25 and a locking nut 26.

The outer surface of the screw 23 has at least one axial flat surface with a curved surface and flat surfaces with threads such that its cross section is non-circular. One end of the screw 23 is fixed on the first connecting rod 21, and the second connecting rod 22 is rotatably sleeved on the screw 23, so that the first connecting rod 21 and the second connecting rod 22 can be rotatably connected.

The fixing cap 24 is rotatably sleeved on the screw 23 and is fixed with the outer side of the second connecting rod 22 into a whole in a welding mode and the like, and round holes matched with the arc-shaped surface of the screw 23 are formed in the fixing cap 24 and the second connecting rod 22. A first tooth face having a plurality of raised teeth is formed on the outer end face of the locking cap 24. The locking plate 25 is sleeved on the screw 23 outside the fixing cap 24, a through hole of the locking plate is matched with the cross section of the screw 23, the locking plate 25 cannot rotate on the screw 23, and a tooth surface two capable of being meshed with the tooth surface one is arranged on the inner end surface of the locking plate 25 and is also provided with a plurality of convex teeth. The locking nut 26 is screwed onto the threaded rod 23 outside the locking plate 25.

The locking nut is screwed to enable the locking piece 25 to be meshed with the fixing cap 24, and the locking piece 25 cannot rotate along the screw 23, so that the connecting rod two 22 is limited to be screwed along the screw 23, and the position locking of the connecting rod one 21 and the connecting rod two 22 is achieved. Through the occlusion of the tooth surface between the locking plate 25 and the fixing cap 24, the locking of the first connecting rod 21 and the second connecting rod 22 can be firmer, and the locking failure of the first connecting rod 21 and the second connecting rod 22, which is caused by the rotating and sliding between the locking plate 25 and the fixing cap 24 due to the small screwing force of the nut and the scalp clip reset force during the plane contact, and the operation error and the operation time extension can be avoided.

An annular space is formed between the outer end of the fixing cap 24 and the screw 23, a spring is arranged in the annular space, and the spring is in a compressed state after the locking piece 25 is meshed with the fixing cap 24. The spring is compressed and stored energy, when the scalp clip is clamped on the incision and needs to be taken out of the scalp clamp, the medical staff outwards unscrews the nut, the locking plate 25 is quickly popped out by the spring to be separated from the fixing cap 24, so that the first connecting rod 21 and the second connecting rod 22 are in locking contact, the two handheld sections can be close to each other, the two spreading sections are folded, the scalp clip is opened and closed to be clamped on the incision, and the scalp clamp is taken out.

The disposable rubber sleeve 12 is sleeved outside the opening section, the rubber sleeve 12 is arranged, on one hand, the opening section can be in elastic contact with the scalp clip, and in addition, the rubber sleeve 12 is used as a disposable article, so that the disinfection treatment of the scalp clip is facilitated, and the cross infection is avoided.

In the scalp clamp, the distance keeping component comprises two permanent magnets with the same magnetic pole, the two permanent magnets are respectively fixed at the tail ends of the two handheld sections, and the two permanent magnets keep a set distance under the action of a magnetic field. The arrangement of the distance can ensure that the two forceps handles 1 keep an effective cross state and can not be crossed reversely, and the minimum allowable distance between the two distraction sections can be met, thereby ensuring effective use.

The round groove has been seted up at the inner circle of ring 11, in the embedded elastic ring 13 that is equipped with of recess, like the rubber circle, elastic ring 13 protrusion in the inner circle of ring 11 increases medical personnel's comfort level of operation use, and elastic ring 13 detachable is changed, is convenient for to the disinfection of scalp clamp.

The above is only the preferred embodiment of the present invention, and any person can make some simple modifications, deformations and equivalent replacements according to the present invention, all fall into the protection scope of the present invention.
