The invention relates to hernia procedures and in particular to an improved hiatal hernia treatment.
Hiatal hernias can cause acid reflux, difficulty swallowing, regurgitation, and pain. In addition, vomiting and gastrointestinal bleeding can occur. Though small hiatal hernias may have some symptoms, large hiatal hernias can be serious and require surgery. For example, a hiatal hernia having limited blood flow may need to be treated through surgery.
From the discussion that follows, it will become apparent that the present invention addresses the deficiencies associated with the prior art while providing numerous additional advantages and benefits not contemplated or possible with prior art constructions.
An improved hiatal hernia treatment is disclosed herein. As will be described further below, the improved hiatal hernia treatment enhances recovery after surgery by directly addressing pain caused by a hiatal hernia treatment. The reduction in pain reduces the need for pain medication, increases patient comfort, and health during the postoperative recovery period.
In one exemplary method, a method for a hiatal hernia treatment is provided, with such method comprising exposing an area of repair containing a hiatal hernia, positioning one or more applicators at a hiatus within the area of repair, and applying an anesthetic at distinct portions of the hiatus with the applicator without pressurization. For example, the application of anesthetic may be gravity driven.
The method may also include adjusting a valve of the applicators, such as to control a flow of anesthetic. A nozzle of the applicators may be adjacent the hiatus when the anesthetic is applied. In addition, the nozzle of the applicators may be within the hiatus when the anesthetic is applied. Anesthetic may be applied to a portion of a diaphragm within the area of repair, to a portion of an esophagus within the area of repair, or both.
In another exemplary method, a method for a hiatal hernia treatment comprises exposing an area of repair containing a hiatal hernia, and positioning one or more applicators at a hiatus. The applicators comprise a reservoir holding anesthetic and one or more valves.
A flow of the anesthetic from the reservoir is provided when the valves are opened. The flow of anesthetic is applied to distinct portions proximate the hiatus with the applicators. The flow of anesthetic is gravity driven. The area of repair may be closed subsequent application of the flow of anesthetic.
A nozzle of the applicators may be adjacent the hiatus when the anesthetic is applied. In addition, the nozzle of the applicators may be within the hiatus when the anesthetic is applied. It is noted that the anesthetic may be applied to a portion of a diaphragm within the area of repair, to a portion of an esophagus within the area of repair, or both.
In another exemplary method, a method for applying anesthetic to a surgical incision is provided, with such method comprising exposing an area of repair of a patient, the area of repair encompassing the surgical incision, positioning one or more applicators at the area of repair, and applying the anesthetic to at least two distinct areas proximate the surgical incision.
The anesthetic is driven through the applicators substantially without pressurization. It is noted that the surgical incision may be sutured prior to the application of the anesthetic. In addition, the area of repair subsequent application of the anesthetic.
A nozzle of the applicators may be adjacent the surgical incision when the anesthetic is applied. In addition, the nozzle of the applicators may be within the surgical incision when the anesthetic is applied. The applicators may comprise a reservoir and one or more valves. The anesthetic may flow from the reservoir and through the applicators when the valves are opened.
Other systems, methods, features and advantages of the invention will be or will become apparent to one with skill in the art upon examination of the following figures and detailed description. It is intended that all such additional systems, methods, features and advantages be included within this description, be within the scope of the invention, and be protected by the accompanying claims.
The components in the figures are not necessarily to scale, emphasis instead being placed upon illustrating the principles of the invention. In the figures, like reference numerals designate corresponding parts throughout the different views.
In the following description, numerous specific details are set forth in order to provide a more thorough description of the present invention. It will be apparent, however, to one skilled in the art, that the present invention may be practiced without these specific details. In other instances, well-known features have not been described in detail so as not to obscure the invention.
The improved hiatal hernia treatment herein is advantageous for patient recovery. A significant amount of tissue dissection occurs during a hiatal hernia repair treatment. This is because such tissue must be dissected in order to access the area of repair. The improved hiatal hernia treatment anesthetizes the area of repair to reduce pain and enhance recover after the treatment is completed.
In an early stage condition, the greater curve 128 at the fundus 116 forms a generally obtuse angle where the greater curve 128 meets the esophagus 112. The same is illustrated in the exemplary anterior view of the abdominal area shown in
In a herniated condition, a portion of the stomach 104, such as the fundus 116, may slide through the hiatus 120 an into the chest. This may be caused by a tear or weakness of the hiatus 120 of the diaphragm 108. A patient may experience chest pain, heartburn or both. In serious cases, blood flow to the stomach 104 may be strangled or limited.
In such cases, surgery may be recommended to repair or reduce the hernia. In addition, in early stage conditions, surgery may be utilized to decrease or reinforce the hiatus 120 to prevent a hiatal hernia from forming or enlarging.
One cause of hiatal hernias is obesity. As such, patients undergoing gastric surgery may also undergo an improved hiatal hernia treatment where by the hiatus 120 is reinforced or otherwise repaired, a hiatal hernia is reduced or repaired, or both as appropriate when an early stage condition or herniated condition is detected.
Referring to
The area of repair 404 shown is below the lungs 408 and adjacent the fundus 116 of the stomach 112. In one or more embodiments, the area of repair 404 will be that containing the hiatus where it meets the esophagus. The connective tissue 412 surrounding the area of repair 404 must be dissected, divided, or both to expose the hiatus and esophagus. Dissection may be accomplished with various laparoscopic instruments. Typically, this area of a patient contains significant amounts of connective tissue 412 which must be dissected or divided before a hiatal hernia can be repaired. This causes trauma to the area.
It is noted that the area of repair 404 may differ, such as by being larger or smaller, for different patients. In addition, more extensive dissection may occur to access the area of repair 404 in some cases. For example, dissection may occur further into the chest cavity, superior to the diaphragm or area of repair 404. As will be discussed below, such dissection may be treated as part of the improved hiatal hernia treatment disclosed herein to aid in patient recovery.
An exemplary area of repair after dissection is shown in
Though illustrated as a posterior repair procedure in
An open end, outlet, or nozzle 608 of the applicator 604 may be used to control the locations at which anesthetic 612 is applied. For example,
As alluded to in the foregoing, an applicator 604 may comprise a tubular structure in fluid communication with a reservoir or source holding a quantity of anesthetic 612. In use, the anesthetic 612 may flow from the reservoir and through the applicator 604 where it may be applied to a surface via the nozzle 608 of the applicator. It is noted that, typically, an applicator 604 will not inject or otherwise pressurize the anesthetic 612 but rather the anesthetic will be driven by gravity out of the applicator's nozzle 608 and onto the desired surface or surfaces.
Application of anesthetic 612 reduces pain at the area of repair for a number of hours after the improved hiatal hernia treatment is completed. In some cases, pain can be reduced for approximately six hours after the improved hiatal hernia treatment is completed. The period of time immediately after a surgical procedure is typically the most painful for patients. Reduction of pain is beneficial in lowering patient stress, discomfort, and heartrate, especially during the postoperative period. In addition, the need for postoperative pain medication, and during the perioperative period overall, is typically reduced as compared to traditional procedures.
The improved hiatal hernia treatment will now be described with respect to the exemplary flow diagram of
At a step 808, a treatment may be executed. In one or more embodiments, the treatment reinforces the hiatus to prevent a hernia from forming or enlarging. A treatment may include repositioning a herniated stomach. A surgical suture, staples, or other reinforcement devices may be sewn, tied, or otherwise implanted to reinforce or repair the hiatus.
After treatment is completed, an applicator may be positioned adjacent a surface at a step 812, such as a surface of the hiatus, diaphragm, or other adjacent structure. The applicator will typically be positioned such that its nozzle is adjacent the surface. At a step 816 anesthetic may be applied to the selected surface, such as by permitting the anesthetic to flow out of the applicator's nozzle. This coats the surface with anesthetic thereby numbing the surface to pain.
At a decision step 820, additional surfaces may have anesthetic applied thereto such as by returning to step 812 to position the applicator adjacent another surface. As illustrated in
Once all desired surfaces have had anesthetic applied thereto, the patient may be closed for recovery at a step 824, such as by removing any instrumentation, pads, or other surgical implements and closing incisions with staples, sutures, or the like. The patient can then proceed to the postoperative recovery stage. As can be seen, the application of anesthetic may be specific to the area of repair, where the patient is likely to experience the most pain after surgery. This is advantageous in reducing the need for other pain medication as while improving patient comfort and heart rate, thereby enhancing the recovery process.
Though described herein with regard to hiatal hernia treatments, it is contemplated that anesthetic may be applied as described herein during a variety of surgeries to directly address pain at various areas of repair. Typically, anesthetic will be applied after a treatment but prior to completion of the treatment (i.e., the end of the surgical procedure). It is contemplated though that, in some embodiments, anesthetic may be applied to an area of repair during the postoperative period, such as by introducing an applicator laparoscopically and applying anesthetic to one or more surfaces, as disclosed herein.
In one or more embodiments, an applicator 604 will be a laparoscopic instrument to permit use while minimizing the size of incisions in the patient. An exemplary applicator 604 is shown in
As disclosed above, in operation, the nozzle 608 of an applicator 604 may be positioned adjacent a selected surface. Thereafter, anesthetic may flow through the applicator 604 and out the nozzle 608 for application to the surface. The flow rate may be controlled by a valve 912 or the like of the applicator 604.
One or more reservoirs 908 may be provided to hold anesthetic. A conduit 904 may connect the inlet 916 of an applicator 604 to the reservoir 908 to allow the applicator to receive anesthetic therefrom. The conduit 904 will typically be flexible to allow free movement of the applicator 604, such as to position the nozzle 608 adjacent a selected surface.
While various embodiments of the invention have been described, it will be apparent to those of ordinary skill in the art that many more embodiments and implementations are possible that are within the scope of this invention. In addition, the various features, elements, and embodiments described herein may be claimed or combined in any combination or arrangement.
