The electric anastomat for the endoscope comprises an installation cylinder and a driving piece, the installation cylinder is fixedly connected with the driving piece, the output end of the driving piece is fixedly connected with a transmission rod, and the outer surface wall of the transmission rod is connected with a pushing cylinder in a screwed mode, and the pushing cylinder is connected with the inner surface wall of the installation cylinder in a sliding mode. In the application, the positioning rod is rotated to enable the open end of the positioning rod to abut against the outer surface wall of the moving cylinder, so that the fixing of the moving cylinder and the mounting cylinder is realized through friction force, subsequently, the driving piece drives the transmission rod to rotate, the transmission rod drives the pushing cylinder to translate, the pushing cylinder is in contact with the transmission block, and the transmission block drives the rack to move and stretches the spring; the rack is meshed with the tooth column to drive the tooth column and the movable anastomosis plate to deflect until the movable anastomosis plate and the fixed anastomosis plate complete anastomosis operation, and therefore the overall length of the electric anastomat can be adjusted, and meanwhile the orientation of the movable anastomosis plate and the orientation of the fixed anastomosis plate can be conveniently adjusted according to requirements.

The invention belongs to the technical field of medical instruments, and particularly relates to a catheter for protecting a stoma intestinal canal in an operation, the catheter comprises a catheter main body, the outer surface of the catheter main body is fixedly sleeved with a bag, and both sides of the outer wall of one end of the catheter main body are fixedly provided with butterfly fixators; a silicone tube is fixedly connected to the outer wall of the end, close to the butterfly fixator, of the bag, and a valve is fixedly connected to the tail end of the silicone tube. The bag almost wraps the whole catheter body, after liquid or gas is injected, an expansion bag with the uniform diameter can be formed, walking of the intestinal canal is shown, an operator can observe the stoma intestinal canal under an endoscope, in addition, the bag can be conveniently inserted into the coiled intestinal canal through the stoma and straighten out the intestinal canal, and the bag can be fixed to the skin and is convenient to use. And finally, the expansion degree of the bag can be correspondingly adjusted according to the use condition of a patient, so that the intestinal canal is prevented from being expanded by the excessively expanded bag.

The lung lobe forceps for the endoscope comprise a first forceps arm and a second forceps arm, the second forceps arm is hinged to the first forceps arm, grips are arranged on the side walls, deviating from each other, of the tail ends of the first forceps arm and the second forceps arm, and the front ends of the first forceps arm and the second forceps arm are bent in the same direction to form a first arc bent part and a second arc bent part respectively. A first forceps head is arranged at the end, away from the first forceps arm, of the first arc bent part, a second forceps head is arranged at the end, away from the second forceps arm, of the second arc bent part, the first forceps head and the second forceps head are water-drop-shaped forceps bodies in the same shape, and water-drop-shaped clamping holes are formed in the first forceps head and the second forceps head. The opposite side walls of the first forceps head and the second forceps head are provided with at least one set of non-damage teeth which are meshed with each other. The ends, away from the first clamp arm, of the first clamp head and the second clamp head are large-diameter ends, and the large-diameter ends and the arc bent parts are bent together to form protruding parts. According to the lung lobe forceps for the endoscope, the mechanical principle is better met when the lung lobe is clamped and pulled at various angles, the operation is more flexible and lossless, and the operation efficiency and the safety in the operation process are improved.

This invention relates to the field of surgical medical device technology, specifically to a laparoscopic purse-string forceps, comprising a clamp, a handle, and a shaft. The clamp includes an upper clamp and a lower clamp, and the handle includes an upper handle and a lower handle. Both the upper and lower handles have movable cavities. A first rotating shaft and a second rotating shaft are fixedly connected to the top and bottom of the upper and lower clamps, respectively. The first and second rotating shafts pass through the bottom walls of the upper and lower handles, respectively, and both are hinged to pistons located within the movable cavities. The sides of the movable cavities away from the first and second rotating shafts are connected to tracheas. A first connecting rod and a second connecting rod are hinged to the sides of the upper and lower handles away from the movable cavities, with the first and second connecting rods hinged together. The shaft contains a pull rod connected to a handle assembly and a corresponding drive assembly. This invention designs a purse-string forceps that can be used in conjunction with a laparoscopy to assist in purse-string suturing within the abdominal cavity.
