Description

Peritoneoscope heating device for gastrointestinal surgery

Technical Field

The utility model belongs to the medical treatment field, concretely relates to peritoneoscope heating device for gastrointestinal surgery.

Background

The laparoscope for gastrointestinal surgery is an instrument with a miniature camera, like a gastroscope. Laparoscopic surgery is a procedure performed using a laparoscope and its associated instruments: the method comprises the steps of using a cold light source to provide illumination, inserting a laparoscope lens (the diameter is 3-10 mm) into the abdominal cavity, conducting an image shot by the laparoscope lens to a post-stage signal processing system through an optical fiber by using a digital camera technology, and displaying the image on a special monitor in real time. Then, the doctor analyzes and judges the state of the patient through images of different angles of the patient organ displayed on the monitor screen, and performs the operation by using a special laparoscope instrument.

When the existing laparoscope is initially arranged in a patient body, the lens of the laparoscope, namely the objective lens, can be fogged immediately due to the fact that the temperature difference between the outside of an operating room and the inside of the patient body is large instantaneously. This is because some of the water vapor is easily condensed on the relatively cold laparoscope lens, so that a layer of mist is formed on the laparoscope lens, which affects the definition of the view field viewed by the laparoscope lens, and further affects the examination or operation process.

Detailed Description

The invention will be further explained with reference to the following figures and examples:

as shown in fig. 1 and 2, the present invention discloses a laparoscopic heating device for gastrointestinal surgery, comprising an inner cylinder 3 made of heat conductive metal and an outer cylinder 1 made of heat insulating material, the outer cylinder 1 totally enclosing the bottom of the inner cylinder 3 and the body of the inner cylinder 3. The inner wall of the outer cylinder 1 is provided with a spiral groove, a spiral electric heating wire 2 is arranged in the groove, and the electric heating wire 2 is attached to the inner cylinder 3. The bottom of inner tube 3 is equipped with power module 6, and the bottom of urceolus 1 is equipped with power socket 5, and power socket 5, power module 6 and heating wire 2 are connected in proper order electrically, will carry out the power supply heating to heating wire 2 by power module 6, then utilize heating wire 2 to heat inner tube 3. The power socket 5 is connected with an external power line and takes 220V electricity. Moreover, the power supply module 6 is a mature component purchased from other companies, and the models thereof are numerous, and the working principle of the power supply module 6 is well known to those skilled in the art and will not be described herein.

The upper part of the inner cylinder 3 is provided with an opening, and the opening of the inner cylinder 3 is provided with a closed structure which comprises a flexible folding layer 7 and a rubber ring 4. The outer edge of the flexible folding layer 7 is fixedly connected with the outer barrel 1 in a full-sealing mode, and the inner edge of the flexible folding layer 7 is fixedly connected with the rubber ring 4 in a sealing mode along the circumferential direction of the rubber ring 4. The inner cylinder 3 is preferably made of silver, such as a silver cylinder, but may also be made of copper or aluminum. The flexible folding layer 7 is a medical silica gel layer coated with heat insulation paint. An ultraviolet lamp 8 is installed at the bottom of the inner barrel 3, and the ultraviolet lamp 8 is electrically connected with the power supply module 6. The inner cylinder 3 and the outer cylinder 1 are provided with water drainage holes at the bottom, and the two water drainage holes communicate the inside of the inner cylinder 3 with the outside of the outer cylinder 1.

In the present case, the throat that the rubber circle 4 formed after the shrink should be less than the camera lens of peritoneoscope, has realized that after the camera lens of peritoneoscope passes through throat and inserts the inner tube 3 the inside, will be under the elastic action at rubber circle 4, the inward flange of flexible folded layer 7 will closely laminate on the outer wall of peritoneoscope. The flexible folding layer 7 in the scheme is not flexible in material, but because the flexible folding layer 7 is radially folded along the plane to realize shrinkage, the flexible folding layer 7 can be deformed along with the rubber ring 4. When the lens of the laparoscope is not inserted into the inner cylinder 3, the necking formed by the contraction of the rubber ring 4 is very small, so that the heat inside the inner cylinder 3 is prevented from being lost through the necking. In particular, a set of heating devices described herein may be used in conjunction with one or more laparoscopes. The heating device is placed on an operating table, the lens part of the laparoscope is inserted into the inner cylinder 3 from top to bottom, and the laparoscope is placed on the outer cylinder 1. The inner cylinder 3 is heated by the electric heating wire 2, so that the internal temperature of the inner cylinder 3 is maintained between 30 and 40 degrees and is close to the temperature in the human body. When the laparoscope needs to be inserted into the human body, the medical staff takes the laparoscope out of the inner cylinder 3, and the temperature difference between the lens part of the laparoscope and the temperature in the human body is small, so that the mist cannot be formed on the lens part.

In the present case, when the lens portion passes through the throat that the shrink of rubber circle 4 formed, under the elastic action of rubber circle 4, the inward flange of flexible folded layer 7 also rubs the lens portion virtually, consequently, provides medical silica gel layer as the flexible folded layer 7 of optimization in this optimized scheme to directly clean flexible folded layer 7. Therefore, as shown in fig. 1, an ultraviolet lamp 8 is further installed at the bottom of the inner tube 3, the lens end is sterilized by the ultraviolet lamp 8, and the ultraviolet lamp 8 is electrically connected with the power supply module 6 and is powered by the power supply module 6. Meanwhile, the bottom parts of the inner cylinder 3 and the outer cylinder 1 are provided with drain holes, and the two drain holes communicate the inside of the inner cylinder 3 with the outside of the outer cylinder 1. When the inner cylinder 3 needs to be washed, the cleaning liquid in the inner cylinder 3 can be discharged through the water discharge hole. In actual use, it is necessary to clean the inner cylinder 3 regularly, because the medical instruments need to be kept clean and sanitary, and especially, the inner cylinder 3 needs to be sterilized by alcohol.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
