Embodiment 1

[0061] In the present invention, the split surgical device includes two parts, the instrument and the surgical power unit. The instrument 28 is provided with a universal snake assembly 284 capable of bending in various directions, and the universal snake assembly 284 is connected with an end effector 286. For example, pliers, tweezers, scissors, etc., the end effector 286 is connected to the end of the universal snake assembly 284 away from the surgical power unit, and the surgical power unit is provided with a surgical instrument driving device 30 for outputting power. When the instrument 28 is connected to the surgical power unit At the same time, the power is output by the surgical instrument driving device 30 to release the traction force applied to one or two adjacent traction wires among the four traction wires, and at the same time, to apply traction force to the other one or two opposite traction wires, To make the universal snake assembly 284 bend to the side of the pu...

Embodiment 2

[0110] Based on the same inventive concept, another embodiment of the present invention provides a surgical power device, referring to Figure 12 ,

[0111] It includes a power host 27 and a handle mechanism 26, and the power host 27 includes the surgical instrument driving device 30 described in the first embodiment.

[0112] The power host 27 also includes a casing, and a surgical instrument driving device 30 is disposed in the casing, and a joint seat 38 for detachably connecting the instrument 28 is provided on the surgical instrument driving device 30 .

[0113] Among them, in the above-mentioned surgical instrument driving device 30, the power source A32 and the transmission part A33 are provided with two groups, which are used to simultaneously drive the four driving rods A341 to slide, and the projections of the four driving rods A341 on the front fixing plate 311 form rectangular divisions , the two driving rods A341 located on the diagonal are driven by the same gro...

Embodiment 3

[0122] Based on the same inventive concept, another embodiment of the present invention provides a split surgical device, referring to Figure 13 , including the surgical power unit and the instrument 28 mentioned above. The instrument 28 is detachably mounted on the surgical power unit.

[0123] The instrument 28 includes an interface seat 281 , an abdominal entry assembly 282 , a universal snake assembly 284 and an end effector 286 which are sequentially connected. The interface seat 281 is used for detachable connection with the joint seat 38 in the surgical power unit.

[0124] The control handle 265 in the surgical power unit controls the surgical instrument driving device 30 through the adjustment ball assembly 266, thereby controlling the universal snake bone assembly 284 to deflect synchronously following the control handle 265 through the surgical instrument driving device 30. The control handle 265 is provided with a finger buckle assembly 263 , for controlling the ...

Abstract

The embodiment of the present invention relates to the technical field of medical instruments, in particular, to a surgical instrument driving device, a surgical power device and a split surgical device. The surgical instrument driving device includes: a front fixing plate and a rear fixing plate parallel to each other, the front fixing A power source A, a transmission part A and a power output part are arranged between the plate and the rear fixed plate; the power source A includes a driving motor A and a driving wheel A, and the driving wheel A is coaxially fixed on the output shaft of the driving motor A; Part A includes a driving wire A, two first guide wheels and two second guide wheels, and the driving steel wire A is wound around the two first guide wheels and the two second guide wheels in turn to form a The first steel wire segment between the second guide wheels; the power output part includes at least two driving rods A spaced apart and arranged in parallel, and each driving rod slides through the front fixing plate, and the two driving rods A are connected to the two sections of the first steel wire. A steel wire segment is connected by transmission in one-to-one correspondence.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of medical instruments, and in particular, relate to a surgical instrument driving device, a surgical power device, and a split surgical device. Background technique [0002] Surgical robot is a complex integrating a number of modern high-tech means, which is widely recognized in surgery. Through surgical robot, surgeons can operate the machine to perform surgery, which greatly improves the safety and convenience of surgery. [0003] In the related art, the driving device of general surgical instruments is driven by screw rod, synchronous belt or gear. Due to the structural characteristics of the transmission structure, there is a gap between the transmission structures during linear forward and reverse motion, resulting in errors in motion. , and to reduce the error of the structural transmission clearance, the contact between the transmission structures needs to be closer, which will ...
