Superficial tumor coating excision device and using method thereof

Abstract

The invention relates to a superficial tumor wrapping and excision device and a using method thereof, and aims to completely wrap a tumor body under the guidance of four-dimensional ultrasonic three-dimensional dynamic data, segment the tumor and suck out the tumor under negative pressure, so the size of a wound is reduced, complete excision of the tumor is ensured, and no residue is left. The extraction sequence and position of the tumor are recorded, the extracted tumor strips are spliced to restore the original shape of the tumor, it is confirmed that the tumor is completely extracted, the conditions of all parts of the tumor can be accurately obtained, and targeted expanded excision is carried out on the lesion position. The tumor body and surrounding tissues can be clearly distinguished in the operation process, unclear boundary caused by bleeding or anesthetic injection in the operation process is avoided, and the integrity and accuracy of tumor body excision are guaranteed. The tumor body is integrally cut, the tumor range is limited, and then excision is performed, so the rotary incision range is limited, the operation is more accurate, the operation is easy, and the operation difficulty and the dependence on the personal experience of doctors are reduced.

Description

technical field [0001] The invention relates to the technical field of surgical instruments, in particular to a superficial tumor encapsulation resection device and its application method. Background technique [0002] The treatment and resection of benign breast tumors are traditionally surgical resection or minimally invasive vacuum rotary excision, each has advantages and disadvantages. Traditional incision surgery is traumatic and requires incision of the skin, subcutaneous tissue, and glands layer by layer. Sometimes the tumor is soft or small and difficult to expose. It needs to be explored during the operation. Guide wire positioning or intraoperative positioning can be accurate, and sometimes positioning is difficult. Layer-by-layer sutures are required after the operation. Most of the postoperative scars are obvious, and many patients feel discomfort. [0003] The minimally invasive method has a small wound on the skin and can be accurately removed. However, the ...

AI Technical Summary

Problems solved by technology

[0003] The minimally invasive method has a small wound on the skin and can be accurately removed. However, the minimally invasive method still has the following problems: (1) When local anesthesia is infiltrated under ultrasound positioning during the operation, the boundary between the tumor and the surrounding tissue becomes unclear, and it is easy to be surgically removed. It increases the difficulty, and the visual field is blurred during accurate resection; (2) when the blood vessel is touched during the resection process, the visual field will be blurred and the tumor body will not be clearly decomposed; (3) the rotary cutter needs to be adjusted in time during the rotary cutting, otherwise It is easy to cut too much normal tissue; (4) The integrity of the specimen is completely destroyed, and the specimen is too fragmented, which makes it difficult for a small number of pathological diagnoses; (5) Individuals encounter difficulty in rotary cutting when there are many mucus components or hard tissues
