The double-petal forceps body comprises two forceps body branches (a first forceps body and a second forceps body), the first forceps body and the second forceps body respectively comprise a holding portion and a forceps rod portion (a first holding portion 21, a first forceps rod body; a second holding portion 22 and a second forceps rod body), the first forceps rod body comprises a first forceps tip 11 at the front end and a first forceps rod portion 13 close to the first holding portion 21, and the second forceps rod body comprises a second forceps tip 12 at the front end and a second forceps rod portion 14 close to the second holding portion 22. When the first and second holding portions 21, 22 are pressed toward each other or released, the first and second forceps tips 11, 12 are moved away from and closer to each other (corresponding to the release and clamping of the first and second forceps tip tips 15, 16, and reference numeral 19 is the forceps tip contact portion between the two in the clamped state). The first forceps tip 11 and the second forceps tip 12 are rotatably connected with the first forceps rod part 13 and the second forceps rod part 14 respectively, and the first forceps tip 11 and the second forceps tip 12 are respectively rotated around connecting shafts (parts shown as 17 and 18 in the figure) between the first forceps rod part 13 and the second forceps rod part 14. In the illustrated example, the first and second tweezer bodies form an X-shaped staggered cross at an intersection 211.
The invention has the advantages that the forceps head is opened to work when in kneading, thereby overcoming the difficulty that the traditional electric coagulation forceps cannot smoothly open the tip of the forceps tip and cannot work due to too small minimally invasive incision, in particular to the endoscope single-hole incision; the first forceps tip 11 and the second forceps tip 12 rotate around the connecting shafts (shown as 17 and 18 in the figure) between the first forceps rod part 13 and the second forceps rod part 14, and the two joints (connecting shaft 17/18) can be adjusted at will according to the actual requirements of the surgeon under a certain strength external force, as shown in fig. 3 and fig. 4, and can be adjusted repeatedly and fixed at a set bending angle, so that the bleeding target points of almost all parts can be reached safely and smoothly by repeatedly adjusting the rotating angles of the two joints (connecting shaft 17/18) in the operation process, and bleeding can be stopped smoothly. The polytetrafluoroethylene coating covers the inner side and the outer side of the elliptical forceps head, only the side edge is left exposed, the generation of eschar can be effectively prevented, complicated water flushing is not needed in the use process, and the serious interference of water dropping on the visual field is reduced.
In the area of the X-shaped cross part 211, the two forceps rod branches are staggered and crossed one by one, so that when the holding part is held, the two forceps tips move towards the direction away from each other.
In some embodiments, as shown in fig. 2, in the front view projection direction, the transition region of each forceps body branch from the holding part to the forceps body, namely the X-shaped intersection 211, is warped upwards from the horizontal direction, namely the X-shaped intersection extends upwards and then extends downwards along a straight line (or a curve). The shape structure can be more convenient for the operation of a doctor.
In some embodiments, the first grip portion 21 and the second grip portion 22 comprise a front portion and a rear portion rotatably connected together, the front portion being rotatable about a connection axis with the rear body. Therefore, the whole electric coagulation forceps have one more joint point with a changed angle, and greater convenience is provided for the operation of doctors.
In some embodiments, as shown in fig. 5, the bipolar coagulation forceps are coated with an insulating layer 31 except for a forceps tip contact portion 19 between the first forceps tip end 15 and the second forceps tip end 16. The contact part 19 of the tip end of the forceps is provided with a polytetrafluoroethylene coating except that the side edge of the contact part 19 is bare metal to ensure electric conduction, so that eschar is prevented from being generated during working.
In some embodiments, the length of the straight line from the holding part to the forceps tip is not less than the distance from the 5 th intercostal to the top of the chest of the male axillary line. For example, in the example of fig. 1, the length of each portion may be selected according to the following dimensions: a is 4cm, b is 6cm, b1 is 2.5cm, b2 is 2.5cm, c is 10cm, and d is 5 cm; the width of the first forceps body and the second forceps body from the holding part to the forceps tip part is gradually narrowed from 0.8cm to 0.3cm, the thickness is 0.2cm, and the forceps tip is in an ellipse shape with a major axis of 0.8cm and a minor axis of 0.4 cm. Other dimensions may also be selected as desired.
In some embodiments, as shown in fig. 5, the insulating layer on the periphery of the connecting shaft 17/18 is covered by the sleeve-type 32, and is not tightly attached to the inner metal material, so that the insulating material is not too much in tension during bending and is not broken during repeated bending and folding, and electric leakage of the electric coagulation forceps occurs.
In some embodiments, the first forceps tip 15 and the second forceps tip 16 are both elliptical. The elliptic electrocoagulation head has small accidental injury to tissues.
In some embodiments, the insulating layers 31, 32 are ordinary plastic insulating layers.
In some embodiments, the polytetrafluoroethylene coating is used for covering the inner side and the outer side of the tip of the elliptical forceps tip, only the side edges are left exposed, the generation of eschar can be effectively prevented, complicated water flushing is not needed in the use process, and the serious interference of water dropping on the visual field is reduced.
