Surgical device and surgical instrument

Abstract

The invention provides a surgical device and a surgical instrument. The surgical instrument includes a handheld end, a connecting structure, an end effector and a driving device; a near end of the connecting structure is mounted onto the handheld end, and a far end of the connecting structure is connected with the end effector; moreover, the connecting structure includes a first flexible structureand a second flexible structure; the driving device includes a first flexible driving structure connected with the first flexible structure and the second flexible structure; and the first flexible driving structure is configured to make the first flexible structure and the second flexible structure rotate in opposite directions. By such configuration, the purpose that more than two surgical instruments are simultaneously inserted into a human body for surgical operations is achieved, and the more than two surgical instruments cannot be interfered during the operations; and preferably, the surgical instruments can also get close to the same target tissue simultaneously, thereby lowering the surgery difficulty.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an operating device and an operating instrument. Background technique [0002] In order to reduce the number of surgical wounds and improve surgical aesthetics, single-port laparoscopic surgery is becoming more and more popular. However, due to the "chopstick effect", ordinary medical instruments (mostly rigid straight rods) need to be cross-operated after being inserted into the body, and it is difficult to use two or more tools to approach a single target area in the treatment tissue at the same time, which increases the difficulty of the operation , Moreover, cross friction will occur when ordinary medical devices are operated at the same time, which not only affects the normal use, but may sometimes cause secondary injury to the patient. [0003] Chinese patent application CN105266856A discloses a glove-type single-hole laparoscopic puncture device. The puncture ...

Problems solved by technology

However, due to the "chopstick effect", ordinary medical instruments (mostly rigid straight rods) need to be cross-operated after being inserted into the body, and it is difficult to use two or more tools to approach a single target area in the treatment tissue at the same time, which increases the difficulty of the operation , and ordinary medical devices will have cross friction when they are operated at the same time, which not only affects the normal use, but may sometimes cause secondary harm to the patient

[0003] Chinese patent application CN105266856A discloses a glove-type single-hole laparoscopic puncture device, which adopts a flexible glove-type puncture device, although it increases the operating space of the doctor's hand-held end , but did not solve the problem of interference between surgical instruments in the abdominal cavity

In addition, the Chinese invention patent CN104352264B also discloses a multi-degree-of-freedom laparoscopic surgical instrument, which is provided with a handle, and a knob is provided at the handle, and the proximal end of the push rod passes through the center of the knob, so that the rotational movement of the knob Control the bending of the bending unit so that the front end can bend in any direction. However, this method requires the operator to operate the push rod separately, and the movement direction of the push rod is opposite to that of the end effector, which is not conducive to the operator to adjust the instrument at any time, and The reverse operation also increases the difficulty of operation
