Problems solved by technology
[0003] In order to solve the above-mentioned problem of clinical use of grasping forceps for minimally invasive surgery, the jaws of minimally invasive laparoscopic surgery grasping forceps designed by the present invention are wide and easy to grasp. The jaws are separated from the body of the operating forceps and inserted into the body assembled by connection

Embodiment Construction
[0026] In order to illustrate the technical solutions and innovative features of the present invention, the following embodiments will specifically illustrate the present invention in conjunction with the accompanying drawings.
[0027] figure 1 , 2 It is a schematic diagram of an embodiment of the present invention, figure 1 In minimally invasive laparoscopic surgery, the jaws of the jaw changing forceps are grasped, and the jaws are separated from the operating forceps body, and inserted and assembled in the body, making full use of the diameter of the sleeve of the operating channel, and the design widens the width of the jaws. When plugged in horizontally, such as figure 1 , 2 As shown, the length of the jaws is not limited by the diameter of the cannula of the operating channel, which increases the gripping area, reduces the unit pressure, and reduces the damage to the tissue, and is the same as the conventional surgical forceps in operation and use.

The invention discloses a pair of minimally-invasive endoscopic surgery grasping jaw replacing forceps capable of replacing jaws, and belongs to the technical field of medical apparatuses and instruments. In a minimally-invasive surgery, a pair of surgical forceps is used for clamping organ tissue mechanically. A minimally-invasive surgical incision is limited by an operation sleeve, the jaw is narrow and small correspondingly, and the requirement for doctor instrument holding precision and controllability is high. Referring to the diameter of the surgical operation sleeve, a traditional minimally invasive jaw is widened and lengthened. When the pair of minimally-invasive endoscopic surgery grasping jaw replacing forceps is in use, the in-vivo transverse plugging mode is adopted, a connector of the minimally-invasive endoscopic surgery grasping jaw replacing forceps is designed into a trapezoid shape, and a wide jaw plugging hole is also designed into a trapezoid shape; a holding catch steel wire is installed on the wide jaw and fixed to a fixing hole in one side of the wide jaw, one end, along the catch steel wire fixing hole, of the wide jaw is a long groove, and the connector of the minimally-invasive endoscopic surgery grasping jaw replacing forceps and the wide jaw catch are fixed through the catch steel wire by means of the long groove inside the jaw. According to the minimally-invasive endoscopic surgery grasping jaw replacing forceps, the jaw area is increased, the clamping force and stability are easy to master, and the phenomenon that congestion, edema and tissue damage of organs are caused due to the fact that clamping pressure of the minimally-invasive endoscopic surgery grasping jaw replacing forceps is excessively large is avoided.
Description
technical field [0001] The invention relates to a surgical forceps, in particular to a minimally invasive laparoscopic surgical forceps. Background technique [0002] The advantages of minimally invasive surgery are less trauma and faster recovery. The jaws of ordinary minimally invasive laparoscopic surgical forceps are correspondingly narrow, and the minimally invasive laparoscopic surgical forceps rely on the mechanical action between the surgical jaws to grasp organs or tissues (such as liver, intestine, etc.) during surgery. Due to the narrow jaws of minimally invasive laparoscopic surgical forceps, it is difficult to control the pressure on the grasped tissue. This requires the surgeon or assistant to accurately maintain the clamping pressure and the clamping position by virtue of clinical experience and the feel of holding the instrument. Be precise. If the jaw area of the minimally invasive endoscopic surgical forceps is large, the clamping strength and stability...
