Problems solved by technology

[0003] The object of the present invention is to overcome the disadvantages of large surgical channel and non-adjustable angle of the existing abdominal forceps that need to be established when performing abdominal surgery, and propose a laparoscopic surgical forceps with adjustable bending angles
The effect of this solution is: the rotatable forceps arm can adapt to different pathological positions and structures during abdominal surgery, minimize the opening of surgical channels, and solve the problem that the existing abdominal forceps cannot be bent and cause large surgical channel openings

Embodiment 1

[0048] Embodiment 1: as attached Figure 8 and 9 As shown, a spring fixing groove is provided at the rotating joint 4 of the pliers arm 1, and the pressure piece spring is installed in the spring fixing groove, and the pull wire is connected to the pressure piece spring. Straightening, so as to achieve the control of the pincer arm 1 to adjust the rotation angle of the rotary joint 4, and realize the state of controlling the pincer arm 1.

Embodiment 2

[0049] Embodiment 2: as attached Figure 10 and 11 As shown, the compression spring provided inside the pliers arm 1 is pulled by a pull wire to adjust the rotation angle of the revolving joints 4 to control the bending angle of each revolving joint 4 of the pliers arm 1 .

[0050] During the use of the present invention, it is first necessary to establish a surgical channel in the abdomen of the patient by means of a trocar. After the channel is established, the turntable 5 is first rotated, and the bottom gear is driven by the turntable 5 to rotate. The flexion and extension of any joint can be controlled by the number of retracted pull loops of the turntable 5, and the rotating joint 4 of the forceps arm 1 can be rotated to a horizontal state through the turntable 5, and then go through the above-mentioned surgical channel to the surgical site, and after entering the surgical site, turn the rotary disc again 5. The spring of the rotating joint 4 is relaxed and automaticall...

Abstract

The invention discloses laparoscopic forceps with adjustable bending angle. The laparoscopic forceps with adjustable bending angle comprises a pair of forceps arms, a forceps body and a pair of forceps handles; each of the forceps arms is provided with at least one rotating joint; each of the forceps handles is provided with a rotating joint regulator; and the rotating joint regulators regulate angles of the rotating joints through pull wires. The laparoscopic forceps with adjustable bending angle disclosed by the invention can adapt to different pathological positions and structures during abdominal cavity operation in virtue of the rotatable forceps arms so as to minimize operation channel, thereby solving the problem of large operation channel opening due to unable adjustment of the bend of the existing abdominal forceps.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and in particular relates to a laparoscopic surgical forceps with adjustable bending angles. Background technique [0002] In clinical applications, it is often necessary to use some surgical instruments with large bending angles for tissue separation, clamping, and blood vessel hemostasis, such as right-angle separation forceps, tracheal dilation forceps, lateral curved needle forceps, vena cava forceps, and renal pedicle forceps. Pliers etc. are widely used. At present, the above-mentioned instruments have the following disadvantages in the use process: firstly, in laparoscopic surgery, in order to facilitate the entry of surgical instruments, a Trocar with a larger inner diameter is required to establish a surgical channel, but too large a surgical channel will not only increase the pain of the patient, but also not conducive to the patient. Postoperative recovery, and after recov...
