Abstract
The utility model provides a microwave scalpel of a celioscope, which not only can rapidly and safely separate tissues, but also can form a protein concretion surface with a certain thickness for a bleeding or blood exudation wound surface, thereby the microwave scalpel of a celioscope has good stanching effect. The head of the microwave scalpel comprises a reversed U-shaped radiation head (1), a movable scalpel head (2), an inner sleeve pipe (7) and an outer sleeve pipe (8); after the movable scalpel head and an arc-shaped metal piece which is arranged at the head of the inner sleeve pipe are closed, the reversed U-shaped radiation head can be surrounded, and a blade which is welded on the movable scalpel head is just inserted in the middle of the U-shaped radiation head. The pincer head of the microwave scalpel is closed to transmit microwaves to a bleeding point and can be used for stanching in a sheet mode or burning tissues. After the tissues are clamped by the pincer head, texture protein can be solidified and then is separated by the blade.
Description
Affiliated technical field
This utility model relates to a kind of micro-wave therapeutic head, is specifically related to a kind of separate tissue and hemostatic operating theater instruments of carrying out fast under peritoneoscope.
Background technology
At present, carry out laparoscopic surgery separate tissue and hemostasis method commonly used clinically and mainly be divided into electric knife and ultrasound knife two classes, electric knife makes by discharge and organizes carbonization, and normal the generation than big smog influences the visual field in the use, to active hemorrhage or trunk blood coagulation weak effect slightly, the scope of application is narrower.Ultrasound knife mainly solidifies histone by ultrasonic concussion cutter head, also can produce a certain amount of smog in the use, to active hemorrhage or the oozing of blood haemostatic effect is relatively poor widely, and costs an arm and a leg and has limited its extensive use in laparoscopic surgery.
Summary of the invention
In order to overcome existing laparoscopic instrument hemostatic problem preferably, this utility model provides a kind of peritoneoscope micro-wave scalpel, this apparatus is chorista quickly and safely, and can form certain thickness protein coagulation face, thereby has good haemostatic effect to hemorrhage or oozing of blood wound surface.
The technical scheme that its technical problem that solves this utility model adopts is: adopt pincerlike cutter head, jaw has the sheet metal of two circular arcs to surround the two sides of " U " font radiation head when closed, make microwave forwards be horn-like propagation, biological effect and penetrance by microwave make the certain thickness protein coagulation of hemorrhage wound surface, water evaporates reaches the purpose of " face coagulate ".After jaw is clamped tissue, microwave is mainly propagated to both sides around radiation head, and after the reflection through both sides circular arc sheet metal, concentration of energy is in the tissue that jaw is clamped again, by embedding the blade of " U " shape spoke shape head central authorities, thereby realize purpose with separate tissue.
The beneficial effects of the utility model are when carrying out laparoscopic surgery, organization security sharp separation such as nethike embrane, mesentery can be able to be formed certain thickness coagulation face to hemorrhage or oozing of blood wound surface.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified.
Fig. 1 is a structure composition diagram of the present utility model.
Fig. 2 is the outside drawing of the active antenna of peritoneoscope microwave ultrasound cutter.
Fig. 3 is the structure chart of the trocar sheath head of peritoneoscope microwave ultrasound cutter.
Fig. 4 is the vertical section structural map of the movable cutter head of peritoneoscope microwave ultrasound cutter.
Fig. 5 is the structure chart of the inner sleeve of peritoneoscope microwave ultrasound cutter.
The 1. microwave radiation heads that fall " U " font among the figure, the circular arc sheet metal on the 2. movable cutter head, 3. movable cutter head connects the movable handle of trocar sheath.4. the arc metal plate of inner sleeve head 5. is positioned at the intermediary blade of movable cutter head, 6. the microwave radiation core utmost point, 7. inner sleeve, 8. trocar sheath 9. clamps handle, 10. holding screw, 11. coaxial cable connector, 12. locking nuts, 13. are welded on the fixed handle of trocar sheath inside.Annotate: above each structural metallic materials surface all scribbles insulating barrier.
The specific embodiment
In Fig. 1, movable cutter head (2) links to each other by the aperture connection activity handle (3) of blade (5) afterbody and the fixed handle (13) inner with being welded on trocar sheath (8), inner sleeve (7) is stretched into by trocar sheath (8) afterbody, the fixed handle (13) of trocar sheath (8) head just embeds in inner sleeve (7) head damaged, stretch out inner sleeve, with the hole on the inner sleeve align with the hole of blade (5) upper forepart pass behind the steel wire fixing, after the microwave radiation core utmost point (6) is stretched into by the inner sleeve head, its afterbody is connected with coaxial cable connector (11), after the other end of the core utmost point forms to fall " U " font, summit and inner sleeve welding.Insert the pincers handle, screw behind the holding screw (10) internal and external casing is fixed with two of pincers handles (9) respectively.Blade behind the occluding forceps handle on the movable cutter head (5) just is embedded in the middle of " U " shape radiation head (1).
Using method: coaxial cable connector (11) is connected with the coaxial cable of microwave power source by locking nut (12), closed microwave coagulation treatment binding clip, point to the petechia launched microwave, can form certain thickness solidifying front to hemorrhage or oozing of blood wound surface, thereby reach the hemostasis purpose.Jaw is clamped tissue, opens microwave switch, histone is solidified the back separate with blade.
Claims (4)
1. peritoneoscope micro-wave scalpel, its head is by falling " U " font radiation head, movable cutter head and internal and external casing are formed, and it is characterized in that: by the sheet metal that is circular arc on movable cutter head and the inner sleeve head, can surround down the microwave operation cutter head of " U " font radiation head after the closure.
2. peritoneoscope micro-wave scalpel according to claim 1 is characterized in that: head be down " U " font and on one side with the active antenna of inner sleeve welding.
3. peritoneoscope micro-wave scalpel according to claim 1 is characterized in that: the outside is the circular arc sheet metal, and the centre is welded with blade and can clamps movable cutter head into " U " shape radiation head central authorities.
4. peritoneoscope micro-wave scalpel according to claim 1 is characterized in that: head is the inner sleeve of circular arc sheet metal.
