Three-vane fan-shaped forceps with passage for minimally invasive surgical operation

Abstract

The invention belongs to the technical field of medical appliances and relates to three-vane fan-shaped forceps with a passage for a minimally invasive surgical operation. The forceps comprise a curvature knob, an opening and closing knob, a tubular forceps rod, a flaky forceps rod, a tubular forceps rod and a three-blade forceps head, wherein the curvature knob is arranged on a handle and used for controlling the curvature of a rod; the opening and closing knob is used for controlling the opening and closing of the three-blade forceps; and the tubular forceps rod, the flaky forceps rod, the tubular forceps rod and the three-blade forceps head are connected in turn. The forceps are characterized in that: the flaky forceps rod is bent in a semi-arc shape and the middle of the flaky forceps rod is provided with an appliance passage. The forceps have the advantages that: after the three-vane fan-shaped forceps with the passage are inserted into a puncture outfit (a puncture passage), other surgical appliances can enter a surgical site through the appliance passage of the flaky forceps. The opening and closing knob is rotated, so that the three-vane forceps head stretches; and the curvature adjusting knob is rotated, so that the field of operation is exposed better. Two different appliances enter one passage, so that the belly wall wound of a patient is minished and the surgical operation of a doctor is facilitated. Operation is simple and convenient and surgical safety is enhanced. The forceps can be applied to a single-hole laparoscope and a multi-hole laparoscope.

Description

technical field [0001] The invention belongs to the technical field of medical instruments for minimally invasive surgery, and relates to a three-leaf fan-shaped retractor, in particular to a fan-shaped forceps with a channel for minimally invasive surgery. Background technique [0002] In minimally invasive surgery, it is necessary to make several puncture channels in the abdomen, usually 3-5 channels. Recently, a channel called single-port laparoscopy has appeared. During the operation, for separation, cutting, hemostasis, suturing, etc., instruments need to be replaced repeatedly. Minimally invasive instruments are long, and the puncture channel enters and exits the instruments, which greatly affects the operation process. At present, during single-port laparoscopy and three-port laparoscopy, one channel is occupied for observation, forceps occupy the second channel, and ultrasonic knife or aspirator occupy the third channel. Can no longer rub into the retractor to expo...

AI Technical Summary

Problems solved by technology

Frequent replacement of instruments not only increases the operation time, but also may lead to surgical misoperation

98% of laparoscopic operations are performed by one person, especially when there is a large amount of bleeding during the operation, good exposure is required for hemostasis, and the surgeon often finds it difficult to perform operations with both hands

And frequent replacement of surgical instruments may increase the risk of surgery
