Dual-function surgical instrument

Abstract

The invention provides a difunctional surgical instrument. A unipolar electric hook push-pull piece is arranged in a shell and can move in the shell; the tail part of the single-pole electric hook is connected with the single-pole electric hook push-pull piece and moves synchronously with the single-pole electric hook push-pull piece; the monopole electric hook is arranged on one side of the energy knife body; the single-pole electric hook insulating sheath is sleeved outside the energy knife body and the single-pole electric hook; the head of the monopole electric hook is exposed out of the monopole electric hook insulating sheath; and the monopole electric hook insulating sheath is fixedly connected with the monopole electric hook. The instrument has the advantages that the function of the monopole electric hook is integrated into the existing high-grade energy instruments such as the ultrasonic knife or the high-grade bipolar Ligature, the high-grade energy instruments and the monopole electric hook are quickly switched, and the high-grade energy instruments do not need to be additionally taken out and then placed into the monopole electric hook, so that the instrument replacement time is shortened, the operation efficiency is improved, and the safety is improved; the structure is simple, size is small and performance is stable and reliable.

Description

technical field [0001] The invention relates to a medical instrument, in particular to a dual-function surgical instrument. Background technique [0002] Surgical laparoscopic surgery has gradually become the current mainstream surgical method. Through an incision of 5-10 mm in size, surgeons can insert small light sources, cameras and surgical instruments. Through the image transmitted to the monitor, the operation of surgical instruments is guided to perform the operation. When this surgery is performed in the abdomen, it is called laparoscopic surgery, and when it is performed in the chest cavity, it is called thoracoscopic surgery. [0003] The current endoscopic surgical instruments are mainly ultrasonic scalpel and advanced bipolar Ligasurse, collectively referred to as advanced energy instruments, and there are also monopolar electric hooks, bipolar separation forceps, etc., among which monopolar electric hooks are the most common for cutting, separating and The bas...

Problems solved by technology

[0003] The current endoscopic surgical instruments are mainly ultrasonic scalpel and advanced bipolar Ligasurse, collectively referred to as advanced energy instruments, and there are also monopolar electric hooks, bipolar separation forceps, etc., among which monopolar electric hooks are the most common for cutting, separating and The basic energy device for hemostasis is often used in conjunction with advanced energy devices such as ultrasonic scalpel or advanced bipolar Ligasure, but frequent replacement of devices will lead to prolonged operation time, and repeated entry and exit of the puncture device will cause damage to the airtight port and air leakage, and may even be caused by replacement. Instruments lead to delays in optimal timing of surgical treatment
