Retracting and cleaning device for brain surgery and using method thereof

Abstract

The invention relates to a retracting and cleaning device for brain surgery and a using method thereof. The retracting and cleaning device comprises a liquid suction rod and a first supporting plate for supporting a thumb is arranged on the outer wall of the liquid suction rod. The device further comprises a supporting mechanism arranged on the side wall, deviating from the first supporting plate,of the liquid suction rod; the supporting mechanism is used for supporting the index finger of the user; a third supporting plate is arranged at the bottom of the supporting mechanism and is used forsupporting the middle finger. According the invention, the brain tissue is pushed aside through the liquid suction rod, so that an operation gap is rapidly and conveniently pulled open and traction-free operation is realized; the situation of brain tissue necrosis can be effectively avoided and non-destructive traction is realized; and due to the arrangement of the supporting mechanism, a doctorcan operate more smoothly and does not feel hurt by hands.

Description

technical field [0001] The invention relates to a retraction and cleaning device for brain surgery and a method for using the same, belonging to the technical field of medical devices. Background technique [0002] Due to the relatively deep location of the skull base and deep brain tumors, the obstruction of the superficial lesion tissue prevents the exposure of the deep lesion tissue during the operation. During the operation, it is necessary to pull the peripheral neurovascular or brain tissue to increase exposure and facilitate tumor resection; Conventional instruments such as suction rods, scalpels, electrocoagulation forceps, and traction devices are required in the traction operation; [0003] The current cleaning device is a suction rod, which is used throughout the operation to clean up fluid, blood and tissue in the brain; however, the surface of the existing suction rod lacks a support and protection structure, and the doctor's Each finger is directly in contact ...

AI Technical Summary

Problems solved by technology

[0003] The current cleaning device is a suction rod, which is used throughout the operation to clean up fluid, blood and tissue in the brain; however, the surface of the existing suction rod lacks a support and protection structure, and the doctor's Each finger is directly in contact with the outer wall of the cylindrical liquid suction rod. During the operation, it is necessary to hold the liquid suction rod for a long time, and the doctor's fingers will be very painful when touched by the rod, which will affect the doctor's finger flexibility and accuracy during operation;

[0004] The current traction device is a retractor and a brain compression plate. The retraction process is as follows: retract the operation gap on the skull, install the retractor on one side of the brain, and then install the brain compression plate on the retractor. Through the operation gap and open the brain tissue, the doctor uses the suction rod and electrocoagulation tweezers to operate on the deep brain tissue; the existing traction device has the following defects: continuous use of the retractor and the brain pressure plate, the brain pressure plate will be damaged for a long time Compress brain tissue, leading to complications such as brain contusion, cerebral edema, and intracerebral hematoma;

[0005] Therefore, both the existing cleaning device and the traction device have defects, which lead to unsatisfactory effect of the traction operation, and too many devices are used in the entire traction operation, which makes the operation complicated, time-consuming and costly

[0006] The patent for invention with the publication number CN105769268A discloses a "flexible retraction assembly, including an expansion balloon made of elastic material that can shrink to enter the lesion and form a retraction channel for the lesion, and communicate with the expansion balloon. The support tube, the connection seat located at both ends of the support tube with the expansion balloon, the locking mechanism coaxially arranged with the support tube and locked with the connection seat, and the expansion or expansion through the connection seat an inflation device connector that deflates the dilation balloon; and a brain compression plate, sleeved at the distal end of the flexible retractor assembly and entering into the retractor channel so that the retractor channel is in a retracted state", the The published patent uses the airbag to expand the brain tissue, thereby increasing the surgical gap, without using a retractor; however, the airbag takes up a lot of space, which easily blocks the doctor's operation line of sight, and is not convenient for the insertion of surgical instruments. The opening and closing gap is not easy to control
