Background technique

Tumors in the base of the skull and deep brain are relatively deep, and the obstruction of the superficial tissue during the operation hinders the exposure of the deep lesion. During the operation, it is necessary to stretch the peripheral nerve blood vessels or brain tissue to increase the exposure and facilitate the removal of the tumor. Conventional instruments such as suction rods, scalpels, electrocoagulation forceps, and traction devices are required in the pulling operation;

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 supporting and protective structure, and the doctor's Each finger is in direct contact with the outer wall of the cylindrical suction rod. It is necessary to hold the suction rod for a long time during the operation. The doctor's fingers will be very painful against the rod, which affects the flexibility and accuracy of the doctor's fingers during operation;

The current traction device is a retractor and a brain pressure plate. The retraction process is as follows: the operation gap is retracted on the skull, the retractor is installed on one side of the brain, and then the brain pressure plate is installed on the retractor, and the brain pressure plate is pierced through the brain. Through the operation gap and open the brain tissue, the doctor uses a suction rod and electrocoagulation forceps to perform surgical operations on the deep brain tissue; the existing traction device has the following defects: continuous use of the retractor and brain pressure plate, the brain pressure plate will be long-term Compression of brain tissue, leading to complications such as cerebral contusion, cerebral edema and intracerebral hematoma;

Therefore, both the existing cleaning device and the traction device have defects, resulting in an unsatisfactory effect of the pulling operation, and too many equipments are used in the entire pulling operation, which makes the operation cumbersome, time-consuming and costly.

The invention patent publication number CN105769268A discloses a "flexible retractor assembly, comprising a dilation balloon made of elastic material and retractable to enter the lesion and form a retraction channel for the lesion, communicating with the dilation balloon. A support tube, a connection seat located at both ends of the support tube with the expansion balloon, a locking mechanism arranged coaxially with the support tube and locked and fitted with the connection seat, and the expansion or expansion through the connection seat an inflation device connector for deflating the expansion balloon; and a brain pressure plate sleeved on the distal end of the flexible retraction assembly and entering the retraction channel to keep the retraction channel in a retracted state", which The open patent uses the airbag to expand the brain tissue, thereby increasing the surgical space and eliminating the need to use a retractor; however, the airbag occupies a large space, which is easy to block the doctor's vision of operation, and it is also inconvenient for the insertion of surgical instruments. The opening and closing gap is not easy to control.
