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 present disclosure provides devices and methods for insufflating abdomens of subjects under direct visualization. Such devices and methods, in some implementations, include features for cleaning the devices, and certain implementations of the methods permit procedures wherein it is not necessary to use a typical obturator to place a cannula, resulting in safer procedures.

The invention has the advantages of simple and convenient operation, reduced surgery risks, and the like.

The invention relates to a vesoperitoneum needle treatment device for female laparoscopy, which includes a workbench, a transport device and a disinfection device. A large rectangular through hole is opened in the middle of the workbench, and a collection box is fixedly arranged at the lower end of the back side of the workbench. A transport device is installed at the left end of the table, and a disinfection device is fixedly installed at the right end of the inside of the large rectangular through hole. The present invention transports the Veress needle through the transport device, and at the same time makes the sterilized Veress needle fall automatically for collection. During the entire transportation process, There is no need to manually operate or stop the equipment, which improves the processing efficiency of the equipment and prevents the Veress needle from being infected. The Veress needle is disinfected and sterilized by the disinfection device, and there is no need to manually wipe the surface, which greatly reduces the cost of the Veress needle. probability of infection.

A surgical device that provides a suction force against a patient's body. The device includes a handle and a suction head pivotally attached to the handle. The suction head includes an open-ended suction chamber having a rim positioned to engage the patient's skin. An actuator on the handle operates a pump to draw a negative pressure in the suction chamber, causing the rim to seal against the patient's skin via the suction force. Once the suction force is initiated, the user may lift the handle away from the patient's body to lift tissue. The lifted tissue provides a site for insertion of a trocar or Veress needle for a laparoscopic procedure in some embodiments. A gimbal disposed between the handle and the suction head provides at least two degrees of freedom such that the handle can be rotated and pivoted to optimize the direction of applied lifting force.

The invention discloses an airbag indicating and locating pneumoperitoneum needle. The airbag indicating and locating pneumoperitoneum needle comprises an outer needle, an inner core and a needle sheath for fixing the outer needle, an opening is formed in the rear end of the needle sheath, the rear end is provided with an elastic airbag, a rotary valve is arranged between the opening and cavity of the needle sheath, the needle sheath is communicated with the cavity through the rotary valve, the rotary valve comprises a barrel body integrated with the needle sheath and a valve body firmly matched in the barrel body, a rotating handle is arranged at one end of the valve body, the other end extends out of the barrel body to form a joint, the valve body is provided with a first passage and a second passage corresponding to the opening of the needle sheath, wherein one end of the second passage is opened, and the opening at the other end of the joint is communicated with the cavity to form the second passage when the first passage is closed. The airbag indicating and locating pneumoperitoneum needle is improved based on an existing pneumoperitoneum needle, the carbon dioxide feeding mode is changed, and the existing method for detecting whether the pneumoperitoneum needle enters the abdominal cavity is changed. By means of the airbag indicating and locating pneumoperitoneum needle, an operator does not need to prepare an injector for injecting normal saline and only needs to use air. The improved rotary valve is convenient for communicating with carbon dioxide, and the valve is very convenient to switch.

A Veress needle having a penetration member (130) that protects a needle tip (112) in order to avoid damage to an organ located inside a puncture site (192) when puncturing a wall portion (190) in a living body. The abdominal needle is provided with a fall-off prevention mechanism (105). The fall-off prevention mechanism (105) has an elasticity-based function by causing the front end portion (134) of the insertion member (130) to protrude from the inner cavity (118) after the puncture is completed. A deformed curved shape so that the needle tip (112) does not fall off from the puncture site (192).

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).
