Deep tissue continuous suturing tool matching with microscope or endoscope in use

Abstract

The invention discloses a deep tissue continuous suturing tool matching with a microscope or an endoscope in use, which is applied to the technical field of medical devices. The deep tissue continuous suturing tool comprises a pair of tweezers and a rotary shaft driving mechanism, wherein the tweezers comprise an upper tweezers body, a lower tweezers body and a handle fixedly connecting the upper tweezers body and the lower tweezers body, a shaft sleeve is arranged on the upper tweezers body, a rotating shuttle mechanism is arranged at a remote end of the shaft sleeve and comprises a rotating shuttle and a line shaft, a rotary shaft capable of driving the rotating shuttle to rotate is arranged in the shaft sleeve, a suturing needle correspondingly matching with the rotating shuttle mechanism is arranged at the remote end of the lower tweezers body, and a needle hole is formed in a tip of the suturing needle. The upper tweezers body and the lower tweezers body are pressed down and then are loosened, the rotary shaft driving mechanism can rotate a circle around the rotating shuttle, and meanwhile, the suturing needle and the rotating shuttle mechanism match to complete once suturing operation. The deep tissue continuous suturing tool imitates the design of the tweezers usually used in a surgery deep operation, so that the use is convenient, the space occupation rate is minimum, components are simple, a purpose of repairing devices by simply changing the components is achieved, and meanwhile, situations that excessive suturing and tissue injury caused by operation errors during the using of external power are avoided.

Description

Technical field [0001] The invention is used in the technical field of medical devices, and particularly relates to a continuous suture tool for deep tissues used with a microscope or an endoscope. Background technique [0002] In surgical operations, it is often necessary to suture deep tissues. However, traditional channel or endoscopic surgery methods have narrow surgical channels and large surgical instruments, which seriously affect the efficiency and operability of deep tissue knotting, such as traditional neurosurgery pituitary tumors Surgical dural repair uses biological material bonding methods, which is a lack of practical alternative methods for suture of deep narrow parts. During the development of deep tissue suture devices, certain patents can achieve the purpose of suture to a certain extent, but the specific use process always has obvious defects. [0003] The invention with application number 200580033739.1 has a complicated design structure and uses an alternatin...

Problems solved by technology

In the traditional endoscopic channel for surgical operation, because the endoscopic channel is narrow and overall long, the design of the instruments passing through it is slender, and the tail end controlled during operation is far away from the working head end, resulting in inaccurate operation. The operation is slow and takes a long time

Secondly, in endoscopic endoscopic surgery, because the operating end of the instrument is located at the end of the endoscopic lens, the large double-ring structure and needle thread in the suturing operation, in the enlarged field of view, its small movement will cause the working end to be unclear.

This invention patent can neither break away from the stereotype of endoscopic surgery. The common problems of endoscopic surgery are inconvenient operation, longer operation time and longer training time, which are more prominent in this invention patent.
