Surgical instrument with bendable actuator

Abstract

The invention provides a surgical instrument. The surgical instrument comprises an actuator, an extension tube and a controller. The near end of the extension tube is connected with the controller, the far end of the extension tube is connected with the actuator, and the actuator can rotate relative to the far end of the extension tube. The controller comprises a bending control mechanism, and the bending control mechanism can move in at least one direction. The extension tube comprises a first flexible part and moves in at least one direction through the bending control mechanism, and the first flexible part enables the actuator to rotate towards at least one side relative to the far end of the extension tube. The invention further provides a bendable nail box. The flexible part enables the actuator to be bent relative to the far end of the extension tube, the actuator can be bent by a larger angle, and therefore the surgical instrument is suitable for medical treatment under the more complex clinical condition.

Description

technical field [0001] The invention relates to a medical device, more particularly to a laparoscopic device. Background technique [0002] A surgical stapler is a surgical instrument that works by closing two corresponding actuators (usually including an anvil assembly and a staple cartridge assembly) to clamp tissue, and then push out the metal staples in the stapler cartridge Shaping, stitching the tissue together. In some staplers, a cutting knife is also installed to cut off the stitched tissue. [0003] With the advancement of technology, traditional surgical methods have gradually turned to laparoscopic surgery. Laparoscopic surgery is to make several small incisions with a diameter of 5 to 12 mm in different parts of the abdomen or chest. Through these small incisions, a camera lens and various special surgical instruments are inserted, and the images of each area in the abdominal cavity captured by the camera inserted into the abdominal cavity are inserted. The i...

Problems solved by technology

In the case where the actuator needs to be bent at a large angle to complete the operation, the use of the actuator with a small bending angle cannot achieve lesion resection in some parts

For example, in low rectal resection, because the space of the pelvis restricts the angle of instruments entering the pelvis, although the nail box actuator turns, the actuator still cannot be sutured and cut at a perpendicular angle to the rectum in some operations, resulting in some Patients with low-lying tumors cannot be treated surgically with the device
