A tumor specimen collection device for surgical operation

Abstract

The invention discloses a surgical tumor specimen collecting device. The device comprises straw, a circular suction cup is arranged at the end of the straw, adjusting rods are arranged on the upper and lower sides of the suction cup and can adjust the diameter of the suction cup, the inside of the suction cup is provided with a liquid suction pipe and a specimen grabbing pipe, the liquid suction pipe and the specimen grabbing pipe both penetrate a piston rod in the straw, the head of the liquid suction pipe is provided with a liquid suction needle located in the suction cup, the head of the specimen grasping pipe is provided with a specimen grabbing hook located in the suction cup, the inside of the specimen grabbing pipe is further provided with a cover plate capable of extending the specimen grabbing pipe to cover the specimen grabbing hook, the other side of the cover plate is provided with an operation rod extending outside the specimen grabbing pipe, the bottom of the straw is provided with a first recovery portion and a second recovery portion which are communicated with the straw, and the first recovery portion is located at the front end of the second recovery portion. Thedevice achieves rapidly tumor tissue collecting and vacuum collecting to prevent the contamination problem in the collection process and transportation process, and the collected amount is relativelylarger, which is convenient for later researches.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a tumor specimen collection device for surgical operations. Background technique [0002] With the increasing influence and harmfulness of malignant tumors on human beings, how to protect, preserve and make full use of human tumor genetic resources and improve the level of cancer prevention and treatment in our country has become a top priority. Therefore, the best way is to collect tumors and conduct research. Therefore, those tumors will be collected before resecting tumors from patients. Tumor tissue specimens as materials for malignant tumor research play an important role in promoting the progress of tumor research. become the foundation of cancer research work. For example, the most common surgical tumor is used. In the current surgical tumor resection process, aspirators, especially ultrasonic aspirators, must be used. The tumor tissue is sucked away by the aspira...

AI Technical Summary

Problems solved by technology

For example, the most common surgical tumor is used. In the current surgical tumor resection process, aspirators, especially ultrasonic aspirators, must be used. The tumor tissue is sucked away by the aspirator, causing most of the tumor specimens to be lost. Tumor tissue clamping with tumor forceps is easy to waste time and manpower, and the obtained tissue is less, especially when it is difficult to obtain deep tumor or tumor tissue, it is easy to cause bleeding problems, resulting in the need for subsequent discharge of excess blood after collection , it is easy for the tumor to be contaminated with dust, which will affect the later detection, so it needs to be improved
