The invention discloses a laser-assisted tumor localization and resection device, which comprises a laser displacement sensor, a cylindrical base, a joint part, a transmission rod, and a data screen, wherein the laser displacement sensor comprises 2 sensors Land L, which are revolvably arranged in the cylindrical base and are coaxial, mounting holes are arranged on both sides of the cylindrical base, the transmission rod is revolvably connected with the cylindrical base at multiple angles through the joint part, the data screen is arranged on the transmission rod. The invention belongs to the field of open surgery or minimally invasive surgery, in particular relates to a laser-assisted tumor localization and resection device that the surgeons use in the minimally invasive surgery and the open surgery to realize the real-time precise intraoperative navigation and tumor localization, ensure the correct surgical plane and enough tumor resection margin and improve the operation efficiency and precision.

Laser-assisted tumor localization and resection device

A method of treating tunnel collapse includes leveling a collapse body and moving a pavilion support under the collapse cavity, lifting a shield plate until a lower edge of the shield plate surpasses a contour line of an initial supporting arch of a tunnel, connecting a bottom column and inserting a padding plate under a column. If the hydraulic prop retracts, the column, the bottom column, the padding plate and the hydraulic prop bear a load from the shield plate. Mounting and connecting the initial supporting arch, welding the intersection point of the column and the initial supporting arch, cutting off the column in the initial supporting arch. Transferring the load of the shield plate from the pavilion support to an initial supporting shed, spraying fast-setting concrete to a grid arch to form a closed shell, and pumping filling material to fill the space of the collapse cavity.

Method of treating tunnel collapse using pavilion support

A method of treating tunnel collapse includes mounting a shield plate, a column, a support column to form a combined support and moving the combined support onto an operation platform, lifting up the combined support, and enabling the height of canopy to be greater than the height of an initial supporting arch. Actively contacting a surface of a collapse cavity by a fixed support column and bearing a load, and lifting a movable support column to the top of the collapse cavity and bearing a load. Mounting an initial supporting arch, and welding the initial supporting arch with the support column. Removing a hydraulic prop after the support column contacting the initial supporting arch is cut off and the load of the shield plate is transferred to a supporting shed. Mounting an exhaust pipe and a filling material pumping pipe, and pumping a filling material into a collapse cavity space.

Method of treating tunnel collapse with roof-contacted shield support
