Retractor for hepatobiliary surgery and application method thereof

Abstract

The invention relates to the technical field of medical apparatus and instruments, and discloses a retractor for hepatobiliary surgery. The retractor includes a beam, supporting plates, plate coats, cross bars, fixing plates and dragging hooks; the supporting plates are fixed on the two sides of the beam, and the bottom of the two supporting plates are provided with the plate coats; connecting blocks are fixed at the bottoms of the two plate coats, and the middle parts of the two connecting blocks are in threaded connection with first threaded rods; and the two first threaded rods respectivelypenetrate the two connecting blocks. During using, two screw rods can be respectively or simultaneously rotated by respectively or simultaneously rotating second rotary knobs, so that the fixing plates on the two cross bars and the dragging hooks on the fixing plates can be away from each other, and therefore, surgical blades can be pulled open; and during the pulling-open of the blades, intern doctors do need to pull the dragging hooks with hands in the whole course, so that the intern doctors can better observe surgical procedures, and therefore, chief surgeons cannot be influenced due to the letting-go of the dragging hooks.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a retractor for hepatobiliary surgery and a method for using the same. Background technique [0002] Medical devices refer to instruments, equipment, utensils, in vitro diagnostic reagents and calibrators, materials, and other similar or related items that are used directly or indirectly on the human body, including the required computer software, which are often required during hepatobiliary surgery. Use the surgical retractor to pull the surgical incision apart, so that the surgeon can perform the operation conveniently. [0003] During surgery, in order to make the intern learn better, the chief surgeon often brings the intern into the operating room to watch the operation process, and when the surgical incision is pulled apart by the surgical retractor, It is often necessary for the intern to pull the surgical retractor to avoid the closure of the surgical incision, ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a drag hook for hepatobiliary surgery and its use method, which solves the problem of soreness and numbness in the hand muscles of interns after the operation due to the contractility of muscle tissue, and for For some interns with weak hand strength, it may cause the retractor to fall out of the hand
