A laparoscopic instrument for forming an incision in a body cavity, insufflating the body cavity with gas, and suturing the incision at the completion of the surgery includes a set of jaws at the distal end of the Veress needle or cannula. The jaws are pivoted to one another for motion between an open position or a closed position in which they may be used to grasp a suture in the body cavity for removal from the cavity for knotting. A push mechanism at the proximal end of the instrument moves the jaws between their open and closed position on successive actuations of a pushbutton and retains them in that state until the next push. An illumination source is provided for the distal end of the instrument to provide illumination through the walls of the body cavity so that the surgeon can determine the degree of penetration of the instrument into the body cavity and can identify any major arteries which should be avoided in the formation of other laparoscopic openings.

The invention relates to the technical field of medical instruments, and discloses a laparoscopic instrument with a sound-absorbing structure, including a Veress needle, a sound-absorbing element and a protective case, a sound-absorbing disc is arranged between the fixed blocks, and the sound-absorbing element Both ends are provided with a first internal thread, the exterior of the sound-absorbing member is provided with a fixing ring, the inside of the fixing ring is provided with a second internal thread, and the surface of the sound-absorbing member at the position of the fixing ring is provided with a second An external thread, a cross bar is installed inside the protective shell, a sphere is sleeved on the cross bar, and a return spring is sleeved on the cross bar on one side of the sphere. This kind of endoscopic instrument with sound-absorbing structure, by setting the fixed ring, the sphere and the return spring, makes the present invention have the function of convenient disassembly and assembly and the function of preventing the loss of gas, without the need of external flow-blocking equipment, and at the same time, it is convenient for users to disassemble and disassemble. The sound parts are cleaned, and the interior is cleaned to effectively keep the noise-absorbing parts clean, prevent patients from being infected, and improve the success rate of the operation.

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).
