초록 ▼

A multifunctional surgical instrument for use in laparoscopic surgery, including a rigid hollow tube, or trocar, mounted on a pistol-grip shaped holder in which a cartridge may be removably mounted, incorporating valves and tubes for connection to a source of vacuum and a source of flushing liquid. The instrument is very simple yet efficient in structure, very handy and easy to use, and designed to allow fast and easy interchange of a tube by another tube incorporating or not electrodes or laser fibers. It can be used through a cannula, not only for irrigation or suction of physiological matter but also for suction of gas or vapors, electrocautery, laparoscopy or laser surgery.

대표청구항 ▼

A multi-functional surgical instrument for use in carrying out laparoscopic surgery, said instrument comprising: A) a pistol-shaped holder, said holder including: (i) a handle shaped as a pistol-grip; and (ii) a hollow cylinder shaped, positioned and oriented as a pistol barrel on top of the handle; said cylinder having an open front end and a rear end, B) a suction and irrigation cartridge mounted within said handle and connectable to a source of vacuum and a source of flushing liquid, respectively, said cartridge including: (i) a three way valve mounted inside said handle, said valve including: first, second and third fluid ports and first and second spring-biased valve plugs operable by first and second push-buttons respectively, said first valve plug being devised to place in fluid communication said first port with said third port when said first push button is pressed, said second valve plug being devised to place in fluid communication said second port with said third port when said second push button is pressed, both of said first and second push buttons projecting outwardly of said handle so as to be easily accessible and operable with a finger when said handle is held in one hand, (ii) a fluid irrigation tube having one end connected to and in fluid communication with the one port of the valve and another end extending outside said handle and connectable to said source of flushing liquid; (iii) a fluid evacuation tube having one end connected to and in fluid communication with the second port of the valve and another end extending outside said handle and connectable to said source of vacuum; (iv) a fluid connection tube having one end connected to and in fluid communication with the third port of the valve and another end connected to a fluid opening provided in said cylinder between the front and rear ends thereof; and C) an interchangeable surgical tool including: (i) a cylindrical shaft sized in diameter and length to fit into said cylinder, said shaft having front and rear ends and including: an annular groove positioned to be in front of and in fluid communication with said fluid opening when said shaft is fully inserted into said cylinder through the open front end thereof; an internal bore opening into said annular groove and extending therefrom up to the front end of the shaft; and sealing means located forwardly and rearwardly of the annular groove to prevent flushing liquid from leaking out of the cylinder when the shaft is inserted therein and liquid is allowed to flow through the annular groove and bore; and (ii) a trocar in the form of a long, rigid tube connected to and projecting substantially coaxially away from the front end of the shaft, said trocar having an open free end distant from said shaft and an internal passage extending between said open free end and the internal bore of the shaft, said passage placing said open free end and said internal bore in fluid communication.
