Description

a tumor peeler

technical field

The invention relates to the field of medical appliances, in particular to a tumor peeler.

Background technique

Tumors may occur in any part of the human body, mostly benign, and benign tumors have a complete tumor wall adhered to normal tissues. Some benign tumors of the surgical system need to be excluded. At present, surgical excision of benign tumors is performed with scissors, knife handle or index finger to blunt or sharply separate the cyst wall from the surrounding tissue and maintain the cyst integrity for easy removal. However, scissors can be used for thick adhesions, and it is easy to cause the tumor to rupture and discharge to the abdominal cavity and pelvis, so that the tumor will grow and recur, and the swelling force will decrease after the rupture of the cyst wall, which also increases the difficulty of peeling. Using fingers to separate the tumor from the human body after surgery is not easy to damage the tumor wall, but the fingers are short and it is not easy to separate the lower segment and base of the tumor. The handle of the knife is relatively straight, which is easy to damage the tumor wall and normal tissue, and is inconvenient to use for larger tumors.

At present, the cutting knives used in the existing tumor peelers are all integrally formed knives, and their lengths are not adjustable. In application, a part of the adhesion between the tumor and the normal tissue needs to be cut, which cannot be completed at one time, and the cutting efficiency is low. In the patent with the authorization announcement number CN 205391141U, a tumor peeler is disclosed, which includes a retractor fixing tube, and the retracting hook fixing tube is sleeved with a tube sleeve, both ends of the retracting hook fixing tube extend from the two ends of the tube sleeve, and the retracting hook is fixed One end of the pipe is provided with a plurality of fixing pieces, and the fixing pieces are hinged with a pulling hook with a pulling hook extension rod. When the tumor mass needs to be taken out, it is only necessary to lift the retractor fixing tube and press the sleeve down, and the two retractors are gathered to the center to clamp the tumor mass, and the tumor mass can be taken out. However, because the retractor has a long rod, the length is not adjustable, the long rod is not suitable for the tumor surface, the cutting effect is poor, and the application value is low; It is not very convenient; there is no mechanism for sucking blood, and the blood may cover the cutting site and affect the cutting operation of the treating doctor, which is not conducive to the diagnosis and treatment of the patient; and because the front end of the long rod is bent into a hook and has a large width, it needs to be extended into the surrounding of the tumor. The larger the space, the greater the damage to the normal tissue around the tumor periphery.
