Detailed Description

The present embodiment is a pair of surgical forceps or surgical scissors for minimally invasive intra-abdominal surgery using laparoscope or the like, and the difference between these two instruments is that the two

portions

102, 103 of the head 100 of the instrument are clamped by the jaws as shown in fig. 1 and 2, or the two

portions

104, 105 of the head 100 of the instrument are the heads of the scissors as shown in fig. 3, and the rest are the same structure. When partial lesion tissues need to be cut by scissors or redundant suture lines need to be removed in the operation, the multifunctional needle holding scissors shown in figure 3 are adopted, and a notch is arranged at the cutting part of the scissors so as to clamp the needle. If hemostasis is desired, a forceps-head instrument, which is a hemostatic forceps, may be used, as shown in fig. 1 and 2. Currently, there are also hemostats or surgical scissors, respectively, suitable for laparoscopic surgery among medical instruments.

Example 1, as shown in fig. 1 and 2: the multifunctional needle holding device of the embodiment is a multifunctional needle holding forceps, and consists of three parts, namely a device head part 100, a handle part 200 and a connecting part 300, wherein the device head part 100 is provided with two parts, namely a fixed part 102 and a movable part 103, and when the fixed part 102 and the movable part 103 are folded, the device can clamp some tissues in an abdominal cavity to stop bleeding or clamp suture used in the abdominal cavity to suture a wound surface. In this embodiment, the fixed part 102 and the movable part 103 are mutually opened when no external force is applied, and the fixed part 102 and the movable part 103 can be realized by using a return spring, which is the same as the structures of some current abdominal hemostats.

In this embodiment, when the fixed portion 102 and the movable portion 103 need to be clamped to hold a needle during a surgical operation, the instrument head portion 100 and the handle portion 200 are connected by a connection wire 303, and the fixed portion 102 and the movable portion 103 can be clamped by pulling the pull wire 303 outward on the handle portion 200, and there are many structures for realizing such functions at present, in this embodiment, the connection portion 300 uses a metal tube with a hollow middle, such as a stainless steel tube, through which the pull wire 303 penetrates, of course, the connection portion 300 can also be a rod with other shapes, the pull wire 303 can run along the rod, the two ends of the connection portion 300 are respectively provided with joints of the pull wire 303, the two similar scissor handles 205 and 206 of the handle portion 200 are used, and a movable handle 205 and a fixed handle 206 are hinged to each other as with the instrument head portion 100, and during the operation, a big mother finger is inserted into the movable handle 206, or an index finger and a middle finger are inserted into the movable handle 206, when the two parts are closed, the pulling wire 303 is pulled outwards, the end part of the pulling wire 303 is also connected with the movable part 103 in the head part 100 of the instrument, and when the connecting wire 303 is tightened, the fixed part 102 and the movable part 103 are clamped. Can clamp tissue for hemostasis and can hold needles.

In this embodiment, when the suture end is to be seen in order to realize needle holding, the instrument head 100 is made to swing around the hinge shaft 301 provided at the end of the connecting portion 300, and the suture can be torn out during the swing. The joint 300 is provided with a hinge shaft 301 at one end of the joint instrument head 100, the instrument head 100 and the joint 300 are connected through the hinge shaft 301 to form a connection structure rotating around the hinge shaft 301, and the joint instrument further comprises a rotating mechanism operating the instrument head 100 to rotate around the hinge shaft 301 at the handle part 200. Such rotary mechanisms are numerous at present, including a tappet 302 disposed through the connecting portion 300 in the middle of the connecting portion 300; the two ends of the tappet 302 are respectively connected with the handle part 200 and the instrument head part 100, and the instrument head part 100 can rotate around the hinge shaft 301 in the left and right directions by using a rigid tappet 302, while in the embodiment, a pull wire 303 is needed for controlling the instrument head part 100 to open or close, because when the instrument head part 100 swings to one side, only the pull wire 303 can be pulled to close the two parts. In the embodiment, the hinge piece 101 is hinged on the side surface of the head part 100 of the instrument, and the hinge piece 101 is hinged with one end of the tappet rod 302; the tappet 302 slides up and down along the middle of the connecting part 300 to drive the instrument head 100 to rotate around the hinge shaft 301; when the tappet 302 pushes inwards, the instrument head 100 swings rightwards, when the tappet 302 pulls outwards, the instrument head 100 swings leftwards, so that the instrument head 100 swings leftwards and rightwards, when a suture line needs to be pulled, the instrument head 100 swings to one side, such as the left side, the forceps clamp the suture needle, the tappet 302 pushes inwards, so that the instrument head 100 swings rightwards to pull out the suture line, then the suture line is inserted from the suture position on the left side, the suture needle is clamped after the suture line comes out, then, the tappet 302 is taken outwards, the instrument head 100 swings rightwards, and the suture can be well sewn in a plurality of times.

In addition, in the embodiment, in the handle portion 200, for the purpose of vitality, a lever 203 of the handle portion 200 is further used as a fulcrum 202, a resistance end of the lever 203 is hinged with the other end of the tappet 302, and an operation handle 201 is arranged at a power end of the lever 203; the operating handle 201 swings to drive the tappet 302 to slide up and down along the middle of the connecting part 300. The lever can save labor. In this embodiment, the handle portion 200 is further provided with a fixing device 204 for fixing the tappet 302 to prevent it from automatically sliding up and down along the middle of the connecting portion 300, as shown in fig. 2, this fixing device 204 is a fixing plate for preventing the lever from moving, and when the swing of the instrument head portion 100 is not required, the operating handle 201 is fixed by the fixing plate to prevent it from swinging.

Example 2 as shown in fig. 3, it differs from example 1 in that two blades are provided in the instrument head 100, forming scissors instead of the jaws in the reference.
