A sample collector for minimally invasive surgery

Abstract

The invention discloses a specimen collector of minimally invasive surgery. The specimen collector of the minimally invasive surgery is mainly composed of a disc-shaped regulation and control device, a sealed collection bottle and a containing bottle, wherein the disc-shaped regulation and control device is capable of changing an absorption channel, the sealed collection bottle is capable of automatically discharging liquid and is provided with a filtering device, and the containing bottle is used for enabling an absorbed content to be heparinized. According to the specimen collector of the minimally invasive surgery, fresh blood is prevented from being coagulated to form a blood clot due to the fact that the absorbed content is heparinized, and the blood clot is prevented from interfering the quality and quantity of a specimen; damage to the specimen of the filtering device caused by enormous pressure on both sides of the filtering device is prevented due to the fact that the filtering device is not part of the absorption channel, the problem that the specimen blocks the absorption channel is solved at the same time, and negative pressure needed for the normal working of an aspirator is guaranteed; the tail end of the aspirator is opened when the aspirator is in a non-working state, the specimen collection bottle discharges bloody liquid continuously, only specimens such as tumor tissues are reserved in the collection bottle, and then space used for containing all specimens collected in the whole surgery process is enabled to be sufficient; and in other surgery stages when specimen collection is not needed, the absorption channel works normally as other ordinary absorption pipes.

Description

technical field [0001] The patent of the invention belongs to the technical field of medical devices, and specifically relates to a specimen collection device for minimally invasive surgery. Background technique [0002] Minimally invasive surgery is the development direction of modern surgery, including various endoscopic surgery and microsurgery, which is characterized by small incision and light trauma. Aspirators (especially ultrasonic aspirators) must be used during the operation, and tissue samples such as tumors are sucked away by the aspirator, causing most of the tissue samples such as tumors to be lost. In particular, the volume of intracranial tumors is relatively small, and most of the specimens are lost, making pathological diagnosis difficult. At the same time, minimally invasive surgery has small incisions, making it difficult to see all the lesions, and it is difficult to estimate the extent of lesion resection during surgery after most of the specimens are ...

AI Technical Summary

Problems solved by technology

[0003] At present, there is no specimen collection device accepted by the majority of clinicians, and the inventions of various specimen collection devices that have been registered for the record all have the following disadvantages: 1. All existing None of the devices considered fresh blood mixed with the specimen

As more and more specimens and fresh blood clots are retained by the filter device, its resistance increases, and the negative pressure of the aspirator head during the operation becomes smaller and smaller, which affects the operation; at the same time, both sides of the filter device The pressure difference is increasing, causing mechanical damage to the specimen; 3. A small number of registered specimen collection devices are composed of a suction tube, a suction tube and a closed specimen collection bottle, and the closed specimen collector retains all the suction contents ( Specimens and fresh blood, etc.), it is difficult to collect all the specimens during the entire operation; at the same time, the coagulation of fresh blood to form blood clots interferes with the quality and quantity of specimens
