Planing knife for joint surgery

Abstract

The invention discloses a planing knife for a joint surgery. The knife comprises a base, a battery slot is arranged on the right side of the base at the position close to the upper surface, a batteryis arranged in the battery slot, the side of the battery slot is connected with a fixing mechanism, a PLC controller is disposed on the right side of the base at the position close to the bottom, anda grip mechanism is disposed on the right side of the base at the position close to the PLC controller. The knife is provided with a medical endoscope and the PLC controller to facilitate observationof the affected part of a patient and facilitate the surgery. By means of a knife groove, knife teeth and a planing knife groove, the affected part can be cut conveniently. By means of an inner tubeand a micro pump, the cut tissues can be collected conveniently. By means of a mounting seat, an outer tube can be removed conveniently to clear the tissues cut through the knife slot. The grip mechanism can be held by a user during the surgery, and is convenient to use.

Description

technical field [0001] The invention relates to the technical field of endoscopic surgical tools, in particular to a planer for joint surgery. Background technique [0002] Endoscopic surgery belongs to the category of minimally invasive surgery. Compared with traditional open surgery, minimally invasive surgery has the advantages of less trauma, faster recovery and fewer complications. Endoscopic surgery is being accepted by more and more patients. The demand for endoscopic surgical tools such as minimally invasive planers has also increased dramatically. During endoscopic surgery, the minimally invasive planers rotate or spin at a high frequency relative to their axes to remove the biological tissue to be removed. In the prior art, planing tools for joint minimally invasive surgical instruments mostly focus on the overall structural design of the hollow outer tube in the cutting part of the planing tool and the inner tube in the corresponding window, and less research is ...

AI Technical Summary

Problems solved by technology

In the prior art, planing tools for joint minimally invasive surgical instruments mostly focus on the overall structural design of the hollow outer tube in the cutting part of the planing tool and the inner tube in the corresponding window, and less research is involved in the serration of the cutting edge, and the teeth of the planer are not sharp enough Due to the unreasonable structure of the knife teeth and the excessive cutting force during the operation, the phenomenon of tearing of the uncut tissue and the phenomenon of planer jamming are not conducive to the smooth progress of the operation, and secondary injuries are likely to occur during the operation and affect the recovery of the postoperative patient.
