Problems solved by technology

At present, in surgical operations, electrodes of different lengths are required due to the different depths of tissue cuts. During specific operations, doctors will use electrosurgical pens with electrodes of different lengths, which is troublesome to switch, and multiple electrosurgical pens cause waste of resources; and the existing electrosurgical pens It is inconvenient to replace the electrodes in the knife pen. For example, the electrodes are divided into electric hook, electric rod, electric knife, electric shovel and electric needle. When using multiple electrodes in the operation, multiple electric knife pens are needed, which is very inconvenient to use

Abstract

The invention discloses a telescopic Intra-operative dissector used for surgical operation. The dissector comprises a housing, a telescopic link, and electrodes. A cavity structure is in the housing,and the housing comprises a shell. The upper surface of the shell is provided with a key boss, and the lower surface is provided with a friction boss, and the front end is provided with a mounting boss. A cavity of the key boss is internally provided with a control circuit board. A cavity of the friction boss is internally provided with a getter device electrically connected with the control circuit board. A cavity of the mounting boss is internally provided with a CCD image collector and an illuminating lamp electrically connected with the control circuit board. Beneficial effects of the dissector are that relative motion of a nut rotary knob and the telescopic link is used to make the telescopic link move accurately, so as to accurately adjust length of the electrode according to depth of a target tissue. A head clamping groove structure of the telescopic link is used, to provide convenience for changing the electrode. Use of the dissector is convenient. The dissector provides convenience for smoke extraction and smoke discharge. The CCD image collector provides convenience for image acquisition, and a computer is used to analyze a dissected approach.

Description

technical field [0001] The invention belongs to the field of medical equipment for shell surgery, and in particular relates to a retractable intraoperative dissector for surgery. Background technique [0002] The dissector used in surgery is an electric knife pen, which is a surgical instrument for cutting surgical tissues. The electric knife pen passes through the electrode through the high-frequency current to reach the target tissue, and the part close to the target tissue and the electrode is rapidly heated and vaporized by the high-frequency current, and the function of cutting and coagulation is realized through the change of the high-frequency current. At present, in surgical operations, electrodes of different lengths are required due to the different depths of tissue cuts. During specific operations, doctors will use electrosurgical pens with electrodes of different lengths, which is troublesome to switch, and multiple electrosurgical pens cause waste of resources; ...
