For better understanding of the technical solutions of the present invention, the following detailed descriptions of the embodiments of the present invention are provided with reference to the accompanying drawings.

It should be understood that the described embodiments are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the embodiments of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

Fig. 1 is a schematic structural diagram of bipolar forceps with rotatable forceps tips according to an embodiment of the present invention. Fig. 2 is a schematic structural view of forceps handles of the bipolar forceps with rotatable forceps tips according to an embodiment of the present invention. Figure 3 is a structure view of the end of the forceps handle provided by one embodiment of the invention. Fig. 4 is a schematic structural diagram of a forceps tip of the bipolar forceps with rotatable forceps tips according to an embodiment of the present invention. As shown in figures 1-4, the bipolar forceps with the rotatable forceps tips comprises a connecting seat 1 and two gun-shaped forceps handles 2, wherein the connecting ends of the two forceps handles 2 are respectively detachably or non-detachably fixedly connected with the connecting seat 1. The tail end of the forceps handle 2 is connected with the forceps tip 3 through a pin. The tail end of the forceps handle 2 is provided with a connecting groove 22, two sides of the connecting groove 22 are respectively provided with a first perforation 21, the connecting end of the forceps tip 3 is provided with a second perforation 31, the connecting end of the forceps tip 3 is arranged in the middle of the connecting groove, the two first perforations 21 and the second perforations 31 are aligned, the pin 5 penetrates through the two first perforations 21 and the second perforations 31, two ends of the pin 5 are respectively provided with an anti-falling piece, and the pin 5 is prevented from falling off from the perforations. Realize the pin joint of the forceps handle 2 and the forceps tip 3. The pinned forceps tip 3 is movable relative to the forceps handle 2.

As shown in fig. 2, both end portions of the connecting groove 22 and the end portions of the forceps tips 3 are arc-shaped. The inner wall 23 of the groove of the connecting groove 22 is arc-shaped and matched with the end part of the forceps tip 3 in an arc shape, after the pin joint, the arc end part of the forceps tip 3 is attached to the inner wall 23 of the groove, and the pin joint is fastened, so that a certain friction force exists in the matching between the forceps handle and the forceps tip, and the arc shape of the upper side of the forceps handle and the arc shape of the tail end of the forceps tip enable the forceps tip to rotate upwards and downwards, so that accidents are prevented.

The attachment groove 22 may be part of the forceps handle or may be a separate component. When the connection groove 22 is a separate component, the other end (the other end opposite to the direction of the forceps tips) of the connection groove 22 is fixedly connected with the forceps handle detachably or non-detachably.

In the operation process, sometimes, the forceps are stressed too much, so that the forceps tips can rotate, in order to prevent the situation, the forceps tips 3 are fixed relative to the forceps handles 2, and the connecting parts of the forceps handles and the forceps tips are provided with clamping sleeves 6 capable of fixing the forceps tips at a certain angle. The cutting ferrule 6 comprises cutting ferrules with different angles according to the angle requirement of the forceps tip 3 relative to the forceps handle 2. In the embodiment, three cutting ferrules of 0 degree, 45 degree and 90 degree are selected, namely a 0 degree cutting ferrule 61, a 45 degree cutting ferrule 62 and a 90 degree cutting ferrule 63, and the structural diagrams of the three cutting ferrules are shown in fig. 5-7.

The 0-degree cutting sleeve 61 is a hoop-shaped structure with a certain length and openings on one side surface and two end surfaces, and is clamped outside the forceps handle and the forceps tip to enable the forceps handle and the forceps tip to be fixed on the same straight line, and the fixed structure is shown in figure 8. The end face of the hoop is square.

The 45-degree cutting sleeve 62 is improved on the basis of the structure of the 0-degree cutting sleeve 61, as shown in fig. 6, one end of the upper wall of the clamping sleeve is removed, a baffle plate with an angle of 45 degrees is arranged on the corresponding lower wall, the baffle plate can be arranged into a right-angle equilateral triangle, two right-angle sides are respectively parallel to and vertical to the lower wall of the clamping groove, and the upper end edge of the triangle and the edge of the upper wall of the clamping sleeve form an opening. When the forceps are clamped, the forceps handle 2 penetrates through the clamping groove, the forceps tip 3 penetrates out of the clamping sleeve from the opening along the triangular oblique edge, and the size and the shape of the opening depend on the size and the shape of the forceps tip 3 at the corresponding position, so that the forceps tip 3 is fixed immovably in the opening. Thereby achieving the purpose of fixing the forceps tip at 45 degrees relative to the forceps handle. The fixed configuration is shown in fig. 9.

The structure of the 90-degree ferrule 63 is substantially similar to that of the 45-degree ferrule 62, except that the baffle is a 90-degree baffle perpendicular to the lower wall of the ferrule; the difference is that the opening of the upper wall of the clamp is larger than the 45-degree clamp sleeve 62, and the size and the shape of the opening are still ensured to be fixed when the corresponding position of the forceps tip 3 is placed in the opening. The 90-degree baffle can be a cube arranged perpendicular to the lower wall of the clamping hoop. When the forceps are clamped, the forceps tips penetrate out of the clamping sleeve from the opening. The fixed configuration is shown in fig. 10.

Two through holes are respectively formed in the opposite positions of the two forceps handles 2, the positioning column penetrates through the two through holes, and positioning rings 4 are respectively arranged at the two ends of the positioning column. The positioning device can ensure that the relative positions of the two forceps handles are stable.

The utility model discloses a when bipolar tweezers assembled, pack into the corresponding tweezers handle respectively with the position ring part, then will correspond the tweezers point of tweezers handle and pack into pin and fixed pin, again will assemble tweezers piece respectively with the joint chair equipment (unanimous with ordinary bipolar tweezers), adorn the cutting ferrule of required angle according to the demand at tweezers point and tweezers handle linking position, fix its angle.
