Problems solved by technology

[0004] The fluorophore positioning device combined with gastroenteroscope and laparoscope to locate and resect the lesion cannot change the size of the fluorophore positioning device according to the size of the lesion, so as to better clamp the lesion, and the operation is cumbersome, and it is not necessary during the operation. It is easy to operate, and it is easy to fall off when the lesion is removed, and it needs to be removed by surgery again, which will cause harm to the patient again. Therefore, we propose a fluorescent body positioning device for positioning by puncture surgery or abdominal surgery to solve the above-mentioned problems.

Abstract

The present invention is a fluorescent body positioning device applied in puncture surgery or abdominal surgery. The size of the fluorescent body positioning device is changed by changing the size of the phosphor, the operation is cumbersome, and the lesion is easy to fall off when the lesion is removed, which will cause harm to the patient again. The following scheme is proposed, including the control box. There are two rotating shafts, and the outer wall of the rotating shaft is fixed with a rotating rod. In the present invention, by pulling the control rod laterally, the opening angle of the fluorescent body positioning device body can be changed according to the size of the lesion, and laparoscopic operation and surgical puncture can be performed selectively. Operation, positioning biopsy operation, laparoscopic operation to remove the lesion, two phosphor positioning device bodies wrap the lesion in the phosphor positioning device body, prevent the lesion from falling, and are easy to use.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a fluorescent body positioning device for puncture surgery or abdominal surgery. Background technique [0002] Medical devices refer to instruments, equipment, utensils, in vitro diagnostic reagents and calibrators, materials, and other similar or related items that are directly or indirectly used on the human body, including the required computer software. The utility is mainly obtained through physical means, not through Pharmacological, immunological or metabolic means, or although these means are involved, they only play an auxiliary role. The purpose is diagnosis, prevention, monitoring, treatment or mitigation of disease; diagnosis, monitoring, treatment, mitigation or functional compensation of injury; examination, replacement, regulation or support of physiological structures or physiological processes; life support or maintenance; pregnancy control; To provide i...
