Description

Multifunctional tumor stripping scissors

Technical Field

The invention belongs to the field of medical instruments, and particularly relates to a pair of multifunctional tumor stripping scissors.

Background

Any part of the human body can generate tumors, which are mostly benign, and benign tumors have a complete tumor wall which is adhered to normal tissues. Some benign tumors of the surgical system need to be removed. Currently, surgical stripping of benign tumors involves blunt or sharp separation of the wall from the surrounding tissue with scissors, handle or index finger and maintenance of cyst integrity for removal. When the existing tumor peeling scissors are used, the tumor is easy to rupture and overflow to the abdominal cavity and the pelvic cavity, so that the tumor recurs, and the expansion force is reduced after the capsule wall is ruptured, so that the peeling difficulty is increased. When the tumor is detached with a finger, the tumor wall is not easily damaged, but the finger is short and is not easily separated into the lower tumor section and the basal part.

At present, cutting tools adopted by the existing tumor dissectors are all integrally formed tool bodies, the length of the cutting tools is not adjustable, a part of the cutting tools is needed to cut the adhesion part of the tumor and the normal tissue when the cutting tools are used, the cutting can not be finished at one time, and the cutting efficiency is lower.

A tumor stripper is disclosed in a patent with an authorization publication number of CN 205391141U, and comprises a drag hook fixing pipe, wherein the drag hook fixing pipe is sleeved with a pipe sleeve, two ends of the drag hook fixing pipe extend out of two ends of the pipe sleeve, one end of the drag hook fixing pipe is provided with a plurality of fixing pieces, and the fixing pieces are hinged with drag hooks with drag hook extension rods. When the tumor mass needs to be taken out, the draw hook fixing tube is only required to be lifted to press the sleeve downwards, the two draw hooks gather towards the center to clamp the tumor mass, and then the tumor mass can be taken out. However, the length of the draw hook with the long rod is not adjustable, the long rod is not suitable for the surface of the tumor, the cutting effect is poor, and the application value is low; the draw hook is only hinged on the fixed part, and has no locking mechanism, so the state can not be stably maintained, and the use is not convenient; the blood stain can cover the cutting part without a blood stain absorption mechanism, so that the cutting operation of a treating doctor is influenced, and the diagnosis and treatment of a patient are not facilitated; and because the front end of the long rod is bent into a hook, the width is larger, and the hook needs a larger space when extending into the periphery of the tumor, so that the hook has larger damage to normal tissues at the periphery of the tumor.

Disclosure of Invention

The purpose of the invention is: the multifunctional tumor peeling scissors can automatically finish the shearing action according to the frequency set by medical personnel, have good applicability, are beneficial to reducing the damage to normal tissues around the periphery of a tumor, have high application value, can cut the whole tumor at one time and have high cutting efficiency; and the device is also provided with a blood stain sucking mechanism, so that the cutting operation of a doctor is facilitated.
