JP-2026514483-A - Surgical devices for suction, irrigation, and tissue traction.

Abstract

A system for surgical suction and/or perfusion is provided, which can be made rigid or flexible. In some embodiments, the system comprises a rod and two flexible and substantially coaxially aligned conduits. The second conduit of the two substantially coaxially aligned conduits can be sealed at its distal end and may have an inner diameter greater than or equal to the outer diameter of the rod. The rod may have an elastic modulus of at least 1 mPa. The second conduit may be configured to pass the rod through it without being removed from the patient while being surgically inserted into the patient. At least a first portion of the first conduit of the two substantially coaxially aligned conduits can be joined to at least a second portion of the second conduit or co-extruded to at least a second portion of the second conduit.

Description

This disclosure relates to surgical instruments, and more specifically, to variable-stiffness suction and irrigation surgical systems. In surgical procedures, it is often necessary to irrigate the surgical field with sterile solutions and/or aspirate body fluids or irrigation fluids from the surgical field. Traditionally, suction/irrigation devices have been designed to function as handheld tools intended for use by the surgeon or surgical assistant. These handheld devices typically incorporate a valve mechanism that the surgeon manually operates to control the suction and irrigation functions. A common valve configuration is known as a "trumpet valve." A trumpet valve consists of an irrigation button and a suction button, each of which can be manually pressed against a compression spring by the operator to engage the valve barrel. Manually pressing the suction button allows suction through the device, while pressing the irrigation button allows fluid to be irrigated through the device. Recently, robot-assisted surgery has been increasingly adopted by surgeons to perform technically challenging procedures in a minimally invasive manner. In robot-assisted surgery, the surgeon uses a robotic console to remotely control robotic arms within the surgical field to perform the surgery. Suction/perfusion devices can be operated by the robotic arms, but doing so would distract the surgeon. In addition, an assistant surgeon may be present at the patient's side to manually operate surgical tools, such as those that cannot be controlled by the robot. Improvements in this area would involve a single suction/perfusion device that can be operated by the robotic arms or manually operated by an assistant at the patient's side, without removing the device from the surgical field. In the first example, a surgical suction and perfusion device is provided, comprising a rod and two flexible and substantially coaxially aligned first and second conduits, the second of which has an inner diameter configured to receive the rod, with the second conduit sealed at its distal end, and the first conduit being in fluid communication with a vacuum source and a perfusion source. Example 2 incorporates the subject matter of Example 1, wherein the rod is at least twice as stiff as the coaxially aligned conduit when tested using Test 1. Example 3 includes the subject matter of Example 1, and the rod comprises metal, metal alloy, steel, stainless steel, glass, or polymer. Example 4 incorporates the subject matter of Example 1, wherein at least a first portion of the first conduit of two substantially coaxially aligned conduits is solvent-bonded to at least a second portion of the second conduit, or co-extruded to at least a second portion of the second conduit. Example 5 incorporates the subject matter of Example 1, and by Test 1, the rod has a stiffness rating of A or B, and the coaxially aligned conduits have a stiffness rating of C or D. Example 6 incorporates the subject matter of Example 1, wherein the second conduit is configured to allow the rod to pass through without being removed from the patient while it is surgically inserted into the patient. Example 7 includes the subject matter of Example 1, wherein the second conduit is shorter and/or narrower than the first conduit. Example 8 incorporates the subject matter of Example 1, wherein the surgical suction and irrigation device is configured to be used to pull the patient's tissue while the rod is inserted into the second conduit. Example 9 incorporates the subject matter of Example 1, wherein the first conduit of two substantially coaxially aligned conduits is configured to perform suction and/or perfusion during surgery. Example 10 incorporates the subject matter of Example 1, wherein the conduit includes a lumen through which it passes, and/or the distal portion of the coaxially aligned conduit is reversibly bendable. Example 11 incorporates the subject matter of Example 1, wherein the first conduit is in fluid communication with the suction/perfusion tip, and the second conduit is not in fluid communication with the suction/perfusion tip. Example 12 describes a method using a surgical suction and irrigation device comprising a rod and two substantially coaxially aligned conduits. The second conduit of the two substantially coaxially aligned conduits can be sealed at its distal end, may have an inner diameter greater than or equal to the outer diameter of the rod, and can pass the rod through it. The method may include performing suction and/or irrigation during surgery using the first conduit of the two substantially coaxially aligned conduits. Example 13 includes the subject matter of Example 12 and further includes inserting the rod into the second conduit. Performing suction and/or perfusion may include performing suction and/or perfusion using the first conduit while the rod is inserted into the second conduit. The method may further include removing the rod from the second co
