Medical Surgical Instruments

Abstract

The existing endoscopic surgical instruments mainly comprise a pneumoperitoneum needle, separating pliers, a casing needle, a switching cap, grasping forceps, a needle holder, an electrocoagulation hook, an application device, scissors, a snare, a line type cutting anastomat, a repair stapler, a retractor, a specimen bag and a hook. Because the material and structural design factors, functions of the surgical instruments are undiversified, the instruments need to be frequently changed to implement multiple actions such as a separation, a shearing, a grasp and a pull, bringing inconvenience to an operator, and prolonging the operation time. To resolve the problems of the endoscopic instruments in the prior art, such as a complex structure, high costs in production and use of an integrated structure, undiversified functions, easiness to damage a tissue, failure to conform to ergonomics and impacts on surgical operations, a medical surgical instrument is provided. The medical surgical instrument comprises a handle, a steering fixing device, a push pipe (1), and a connecting rod (2). The handle is of an integrally-formed structure or a whole structure formed by connected segments, and comprises a transverse arm (3) and a vertical arm (4).

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 retractors, 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 connect...
