DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to a surgical device for internal use during surgical operations in body cavities, particularly during abdominal operations.
BACKGROUND ART
During abdominal operations it is ordinarily necessary to push the gastrointestinal canal aside to keep the place at which the operation is performed free and easily accessible. With this end in view, it is well known to maintain the intestines in a fixed position by utilizing liquid-absorbing cotton sheets and wound retractors which are manually held during the operation by one or more nurses assisting the surgeon.
The use of such cotton sheets and wound retractors present several drawbacks. Thus, the use of cotton sheets does not prevent the retracted intestines from being gradually released and causing inconvenience to the surgeon because the assistants gradually get tired of holding the cotton sheets and wound retractors or because the cotton sheets, due to their limited liquid absorption capacity, from time to time have to be replaced with new cotton sheets. The replacement of the cotton sheets not only delays the surgical operation but may also result in the operation is not performed at the most suitable time.
Furthermore, small particles may be released from the cotton sheets into the body cavity, which are then difficult to remove.
The object of the present invention is to provide a surgical device for use in body cavities and for maintaining organs, such as intestines, in a fixed position during an operation without the aid of assisting personnel and without damaging the organs.
SUMMARY OF THE INVENTION
This object is attained by the surgical device of the invention, this device being rod-shaped and comprising a non-elastically deformable, flexible member surrounded by a soft, liquid-absorbing material which is optionally is enclosed in an overwrap.
The presence of the non-elastically deformable, flexible member in the surgical device of the invention has the effect that the rod-shaped device, after being suitably shaped to keep organs, such as intestines, in a given position, maintains the shape thus imparted to it, thus making manually held devices superfluous. Since the non-elastically deformable member is surrounded by the soft liquid-absorbing material, the bending of the device around the organs will cause no damage to them.
The presence of the liquid-absorbing material also has the effect that exuded liquid, such as blood, is collected and is prevented from interfering with the operation.
In view of the fact that the thickness of the liquid-absorbing material surrounding the non-elastically deformable member can be varied without any significant adverse effect on the flexibility of the device of the invention, the liquid absorption capacity of the device may be varied within wide ranges and as required.
A high liquid absorption capacity of the device of the invention may be of vital importance for a successful operation. Thus, in case the patient loses blood during the operation, the blood is absorbed in the liquid-absorbing material and the amount of blood lost can be measured at intervals by withdrawing the device from the body cavity and removing the blood therefrom by squeezing. By determining the amount of blood lost, the anaesthetic can be more correctly dosed because the dosage of anaesthetic depends on the remaining amount of blood in the patient.
A preferred embodiment of the invention comprises a perforated, flexible tube incorporated in the liquid-absorbing material and adapted to be connected to a suction device, e.g. a pump, via a liquid collector.
When using this embodiment of the surgical device of the invention, the blood absorbed in the liquid-absorbing material can be continuously removed therefrom and collected in the liquid collector, thus permitting the amount of blood lost to be continuously recorded.
U.S. Pat. No. 3,923,052 discloses a fenestrated surgical drape comprising one or more sheets of a non-woven material and strips of a non-elastic deformable, flexible material. The purpose
