Medical surgical instrument

Abstract

The existing endoscopic surgical instruments mainly comprise a pneumoperitoneum needle, an elastic separating plier, a trocar, a conversion cap, a grabbing nipper, a needle holder, an electro-coagulation hook, an applicator, a scissor, a snare, a linear cutter anastomat, a repairing stapling device, a retractor, sample bags and pull hooks, and the like. Because of the material and structural design factors, the surgical instruments are unitary in function, the instruments are in the needs to be constantly replaced in the use process so that the multiple separation actions of cutting, grabbing, pulling, and the like are completed, the process brings inconvenience for patients and lengthens the operating time. In order to solve the problems that in the prior art the endoscopic surgical instruments are complex in structure, the integrated structure is high in production and use cost, the function is unitary, the tissues are easily damaged, the criteria of human engineering is not met, the surgical operations are affected and the like, the invention provides a medical surgical instrument, the instrument comprises a handle, a rotating fixture, a push pipe and a connecting rod; the handle is a molding structure overall, or after the subsections are formed, the subsections are connected into a whole structure, the whole structure includes a cross arm and a vertical arm.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to medical surgical instruments. Background technique [0002] Existing endoscopic surgical instruments mainly include Veress needles, separation forceps, trocars, conversion caps, grasping forceps, needle holders, electrocoagulation hooks, applicators, scissors, snares, linear cutting staplers, repair staples devices, retractors, specimen bags and hooks, etc. The operation mode of the existing surgical instrument handle is single, and most of them are clamped by fingers. Long-term use during the operation may easily cause finger fatigue and wrist damage. In addition, when clamping and pulling tissues, it is necessary to rotate the wrist to change the working direction of the instrument. Finding a suitable working point brings great inconvenience to the operation; at present, surgical instruments adopt a stainless steel multi-piece hinge structure, which is connected wi...
