A kind of multifunctional tumor stripping scissors

Abstract

The invention discloses multifunctional tumor stripping scissor. The scissor comprises a handle, an outer knife tube connected to the handle in a manner rotatable about an axis thereof, an inner knifetube sleeved with the outer knife tube, a scissor body, a driving motor, a flat pushing sleeve and a rotating sleeve, the right end of the inner knife tube extends out of the handle and is connectedwith a liquid suction hose, the scissor body comprises two curved blades coaxially hinged to the left end of the outer knife tube, the left end of the inner knife tube is respectively hinged to the two curved blades through two connecting rods, the driving motor is disposed in the handle, the flat pushing sleeve is located in the handle, is fixedly sleeved in the inner knife tube and is cooperatedwith a flat pushing gear through a thread, the driving motor can drive the flat pushing gear to rotate, and drive a flat pushing sleeve head and the inner knife tube to reciprocate axially together to achieve the shearing action of the scissor body, and the rotating sleeve is fixedly sleeved with a rotating gear. The stripping scissor can automatically perform the shearing action, and have good applicability and high cutting efficiency.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a multifunctional tumor stripping scissors. Background technique [0002] Tumors may occur in any part of the human body, and most of them are benign. Benign tumors have a complete tumor wall that adheres to normal tissues. Some benign tumors in the surgical system need to be excluded. At present, in surgical dissection of benign tumors, scissors, knife handles or index fingers are used to bluntly or sharply separate the cyst wall from the surrounding tissue and maintain the integrity of the cyst for removal. When the existing tumor stripping scissors are used, it is easy to cause tumor rupture and discharge to the abdominal cavity and pelvic cavity, which will cause tumor recurrence, and the swelling force will decrease after the capsule wall ruptures, which will also increase the difficulty of stripping. Although it is not easy to damage the tumor wall when using fi...

Problems solved by technology

However, since the retractor has a long rod, the length cannot be adjusted, and the long rod is not suitable for the surface of the tumor, the cutting effect is poor, and the application value is low; the retractor is only hinged on the fixing part, there is no locking mechanism, and the state cannot be stably maintained. Not very convenient; there is no mechanism for sucking blood stains, blood stains may cover the cutting site and affect the doctor's cutting operation, which is not conducive to the patient's diagnosis and treatment; and because the front end of the long rod is bent into a hook with a large width, it needs to be inserted into the surrounding tumor Larger space, greater damage to normal tissues around the tumor
