Description

Technical Field

[0001] This disclosure relates generally to surgical devices, and more specifically to a surgical pen for providing suction and blowing during surgery. Background Technology

[0002] Surgical electrocautery (ES) pens are commonly used in surgery to cut tissue and / or to induce vascular coagulation. ES pens typically include a handheld component in which electrodes of various shapes and sizes can be placed. The electrodes are supplied by an ES generator (such as Medtronic's Valleylab). TM The LS10 or FT10 generator provides high-frequency (usually radio frequency (RF) AC) power. The ES generator can supply various waveforms suitable for achieving various surgical effects (such as cutting, coagulation, fusion, jetting, electrocautery, etc.).

[0003] When using an ES pen, smoke is typically generated. An effective way to remove surgical smoke is to use an ES pen with an integrated smoke exhaust nozzle in conjunction with a suction device and an ultra-low permeability air (ULPA) filter. Conventional ES pens rely on a smoke exhaust hood attached to the pen, which draws the smoke away via the suction device. The smoke exhaust hood can be an integral part of the ES pen or a separate cover attached to it. The smoke exhaust nozzle (located near the pen's electrodes) draws in streams of smoke, which pass through the pen body, through a long, flexible tube, and finally into the powered suction device outside the surgical field.

[0022] The following drawings and description illustrate details of one or more aspects of this disclosure. Other features, objects, and advantages of the technology described in this disclosure will become apparent from the description, drawings, and claims. Attached Figure Description

[0023] Various aspects of this disclosure are described below with reference to the accompanying drawings, in which:

[0032] Figure 9 yes Figure 4 A side cross-sectional view of the proximal portion of the electrode assembly. Detailed Implementation

[0033] In this specification, the term "proximal" is generally used to refer to the portion of the device closer to the clinician, while the term "distal" is generally used to refer to the portion of the device farther from the clinician. Furthermore, the term "clinician" is generally used to refer to medical personnel, including doctors, nurses, and support staff.

[0034] As fumes accumulate at the surgical site due to electrical stimulation of tissue, visualization via laparoscopes or other visualization devices becomes blurred, obscuring the clinician's view of the surgical site during the procedure. Additionally, bleeding points may be difficult to locate during the procedure because the tissue is covered in blood, making it difficult for clinicians to precisely determine where to cauterize the tissue to stop the bleeding.

[0035] To provide better identification of bleeding points and visualization of surgical sites during surgery, this disclosure provides a surgical system comprising surgical instruments for simultaneously providing fluid aspiration (e.g., carbon dioxide aspiration) and smoke aspiration at the surgical site. As described below, fluid aspiration from the distal end of the instrument disperses blood films away from the tissue to expose bleeding points and simultaneously provides the function of diluting surgical fumes present at the surgical site. Meanwhile, a dual-lumen device enables the aspiration of smoke fumes from the surgical site. The instrument includes an electrode assembly having an electrode at its distal end, which, when placed near tissue, can be sprayed with fluid (e.g., carbon dioxide) to aspirate blood-covered bleeding points. Simultaneously, the electrode, or another portion of the disclosed electrode assembly, can absorb / aspirate smoke fumes, providing a clear view for endoscopes, laparoscopes, or other visualization devices, thereby reducing the time required for smoke removal, shortening operation time, and reducing the risk associated with clinicians inhaling any fumes generated during surgery.

[0036] Figure 1 An exemplary surgical system 1 is illustrated, which includes a surgical generator 100, a smoke extraction system 200, a fluid source 300, and a surgical pen 10 configured to be connected to the surgical generator 100 to deliver surgical electrical energy generated by the surgical generator 100 to tissue. Additionally, the surgical pen 10 is configured to be connected to the smoke extraction system 200 to exhaust surgical smoke from the surgical site and to the fluid source 300 to introduce fluid into the surgical site.

[0037] Figures 2 to 9 A surgical electroplasty pen 10 and its components are shown. Typically, the surgical electroplasty pen 10 includes: a handle 14; a manifold 15 disposed within the handle 14 and operatively connected to a suction tube 18 and a blower tube 16; and an electrode assembly 20 removably connected to the manifold 15. A proximal portion 20A of the electrode assembly 20 is configured to be releasably connected to the manifold 15, and an electrode 25 extends from a distal portion 20B of the electrode assembly 20. The suction tube 18 defines a lumen configured to drain fluid from the surgical site, and the blower tube 16 defines a lumen configured to deliver fluid (e.g., carbon dioxide) to the surgical site.

[0038] The electrode assembly 20 includes an outer tubular member 28, an inner tubular member 26, and an electrode 25. The outer tubular member 28 defines at least one suction port 28A and a suction cavity 28L in fluid communication with the cavity defined by the suction tube 18. The inner tubular member 26 is disposed within the suction cavity 28L of the outer tubular member 28 and defines at least one blower port 26A and a blower cavity 26L in fluid communication with the cavity defined by the blower tube 16.

[0039] Electrode 25 is configured to deliver surgical electrical energy to tissue. Electrode 25 can be of any shape suitable for a given surgical procedure, such as hook electrode 25B. Figure 6 ) or shovel-shaped electrode 25A ( Figure 7 Additionally, the extension tube 25E surrounds at least a portion of the electrode 25 and is in fluid communication with the blower cavity 26L of the inner tubular member 26 to transfer fluid from the fluid source 300. Figure 1 The fluid (e.g., carbon dioxide) is delivered to the vicinity of electrode 25. By positioning the blower port 26A and / or extension tube 25E near electrode 25, the fluid (e.g., carbon dioxide) can be sprayed onto electrode 25 and the tissue being treated by electrode 25 to blow away blood-covered bleeding points or any tissue, assisting clinicians in identifying the location of bleeding. Once the bleeding point is identified, the clinician can treat the tissue at the bleeding point with electrode 25 (e.g., cauterize).

[0040] The suction port 28A can be a single or multiple ports defined along the length of the outer tubular member 28. Additionally, one or more suction ports 28A can be positioned proximal to the blower port 26A along the longitudinal length of the surgical pen 10 so as not to interfere with any fluid delivery through the blower port 26A. Simultaneous blowing and suction allows clinicians to clearly visualize the surgical site using a visualization device (e.g., an endoscope).

[0041] 50 power cable Figure 1 Electrode 25 is electrically connected to surgical generator 100. For example, power cable 50 may extend through at least one of blower tube 16 or suction tube 18 to reach the interior of handle 14. On one hand, the distal end of power cable 50 is electrically connected to circuit board 52 disposed within handle 14, which may be controlled by switch 53 extending through handle 14 and operable by a user. Electrically downstream of switch 53, circuit board 52 is electrically connected to inner tubular member 26. Inner tubular member 26 is conductive and electrically connected to electrode 25. For example, clip 26C may be formed on the inner surface of inner tubular member 26 to attach electrode 25 to inner tubular member 26.
