A device for visible puncture includes a balloon, a canula, a needle tube, an image acquisition device, and a fluid injection tube. The balloon includes a first end including a first hole, and a second end including a second hole. The canula includes a first axial through hole. The needle tube includes a second axial through hole and is disposed in the first axial through hole. The image acquisition device is disposed in the second axial through hole. The balloon is axially disposed on the canula. The first end of the balloon is disposed on the outer wall of the front end of the needle tube, and the second end of the balloon is disposed on the outer wall of the front end of the canula. The second axial through hole includes a fluid channel disposed between the outer wall of the needle tube and the canula.

Device for visible puncture

An endoscope, including: a handle, a sheath tube, an endoscopic cannula, and a tensioning mechanism. The sheath tube includes a first axial guide hole and a first joint pin disposed in the first axial guide hole. The handle includes a second axial guide hole and a second joint pin disposed in the second axial guide hole. The first joint pin matches and is directly connected to the second joint pin. The sheath tube matches and connects to the handle. The handle includes a cavity and the tensioning mechanism is disposed in the cavity. The endoscopic cannula includes a flexible part extending out of the sheath tube and a rigid part fixed in the sheath tube. The flexible part includes a steering wire. The first joint pin is connected to the steering wire. The tensioning mechanism is connected to the second joint pin.

Endoscope

A self-locking angle adjustment mechanism for an endoscope includes: an endoscope angle adjustment steel wire (), a rotation handle (), an endoscope handle () and a self-locking rotation device, wherein: an outer conical surface is provided at an external surface of the rotation shaft (), a conical cylinder is sleeved onto the outer conical surface; a spring (), which can drive the rotation shaft to move towards a direction of the conical cylinder or drive the conical cylinder to move towards a direction of the rotation shaft, and can force the inner conical surface to closely fit with the outer conical surface for self-locking, is located along an axial direction of the rotation shaft or conical cylinder. Through the present invention, the flexible sheath is locked stepless at any position, meeting free positioning requirement of endoscope during surgeries, reducing labor strength during surgeries, avoiding patient injuries caused by misoperations.

Self-locking angle adjustment mechanism for endoscope

The present invention relates to a multidirectional turning endoscope, which includes an insertion portion (), an endoscope handle () and a bending driving portion (); wherein: the bending driving portion includes a left-right driving rod, an up-down driving rod, a rotation shaft, a left turning wheel (), a right turning wheel () and a spring (); the rotation shaft includes a left half shaft () and a right half shaft (); the external surface of the left half shaft and the external surface of the right half shaft respectively have a left outer conical face and a right outer conical face, a left conical cylinder and a right conical cylinder () are respectively sleeved to the left outer conical face and a right outer conical face; a spring () is located at an axial direction of the left half shaft and the right half shaft.
