Problems solved by technology

The existing surgical planning system cannot meet the special requirements of Mohs surgery, and consumes too much manpower and material resources
Such as: Prior Art 1 (Application No. CN201210417086.9:, Publication No.: CN102961187A) discloses a surgical planning method and system for percutaneous puncture, which requires the establishment of three-dimensional models and virtual operations for each operation. Previously, it took a lot of time and manpower, and the problems of skin displacement and quadrant marking in Mohs surgery could not be solved

Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] see Figure 1-4 , a surgical planning system, which includes a skin adhesive ring (not shown in the figure), a mechanical arm 2 and a laser marking device 4 . The skin adhesive ring is attached to the periphery of the patient's skin before the operation; there are three laser marking devices 4, all installed on the mechanical arm 2, and the realization of its functions is controlled by a computer (an example of a controller) .

[0023] The skin adhesive ring fixes the skin tissue, thereby preventing displacement of the skin tissue. For Mohs surgery, the displacement of the skin tissue will make it difficult to determine the position of each part of the skin, which will bring great inconvenience to the resection of the residual tumor, increase the possibility of surgical failure, and even increase the possibility of cancer recurrence in patients grea...

Abstract

The invention discloses a surgical planning system, including a controller, a laser marking device and an image acquisition device. A surgical cut path information is stored in that control, the lasermarking device is used for projecting the surgical cutting path information to a part to be operated of a patient through a laser, At least three laser marking device are provided, and that laser projections of all the laser marking devices on the part to be operated coincide with each other, and the image acquisition device is used for acquiring images and transmitting the images to a conveyingcontroller. The system can facilitate accurate excision of skin tumors by Mohs operation, and greatly reduces the possibility of residual pseudopodia of tumor cells.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an operation planning system, especially suitable for Mohs operation planning. Background technique [0002] With the change of life pattern of Chinese residents and the increase of outdoor activities, the incidence of skin tumors in China has been increasing year by year, and has become one of the most common tumors in humans. Mohs surgery is one of the most commonly used surgeries in skin plastic surgery and even in the treatment of skin tumors. First, the Mohs operation can thoroughly check whether there is any tumor residue on the side wall and bottom of the skin tumor by observing the frozen microsection. The biggest advantage of the Mohs operation is to remove all the tumors and ensure the minimum postoperative skin defect. However, at present, the surgical path planning of Mohs surgery is completely done manually, which consumes a lot of time and energy, and there will b...
