Abstract
The utility model discloses a hepatic portal blocking belt under a laparoscope, which comprises a clamp, a belt body and a tongue depressor; saw-toothed protrusions are arranged on one surface of the belt body; a clamp is fixed at one end of the belt body; a through groove is formed in the surface of the clamp; the inner surface of the through groove of the hoop is provided with a pressing tongue; a buckle is arranged on one surface of the pressure tongue corresponding to the sawtooth-shaped bulge of the belt body, and the buckle is matched with the bulge; when the tongue depressor is pressed downwards, the belt body only enters in one direction; the blocking belt can play a role in blocking the hepatic portal at any time in an operation, and compared with a binding pipe, the blocking belt reduces the influence on the main knife and an assistant in the operation process and reduces the operation risk.
Description
Technical Field
The utility model relates to the technical field of medical surgical instruments, concretely relates to hepatic portal blocking belt under peritoneoscope.
Background
With the rapid development of laparoscopic liver resection in recent years, the application of the portal blocking technique is also becoming more and more important. The application of the hepatic portal blocking technology effectively reduces the amount of bleeding in the process of laparoscopic hepatectomy and reduces the probability of abdominopexy transfer caused by massive bleeding in the operation. The hepatic portal blocking device or instrument is needed for hepatic portal blocking, and is an accessory device for laparoscopic hepatectomy, which performs intraoperative hemostasis to more successfully complete surgery, and is widely used in the medical field. The conventional laparotomy achieves the purpose of reducing bleeding by using various vascular clamps and blocking blood flow which interrupts the first hepatic portal and the like. However, there are few special instruments in laparoscopic surgery, and especially, instruments for hepatic portal block are mostly replaced by manual or other instruments.
Currently, two methods are commonly used for performing hepatic portal block under an endoscope, namely the Pringle method, one is to lead out extracorporeal block by means of a sleeve, but a poking card hole or an incision is required to be added, and the operation visual field is influenced. The students also adopt the silicone tube (or plastic hose) to combine with the Hemlock clamp for blocking, but the students waste time and labor, and the blocking is not thorough and the cost is high.
The utility model has the following contents:
according to prior art's not enough, the utility model provides a hepatic portal blocking area under peritoneoscope can play in the operation through this blocking area and block the hepatic portal effect at any time to block the area and compare the constraint pipe and reduced the influence that brings main sword and assistant when the operation, reduced the operation risk, the expense is also more economical than current hepatic portal blocking device.
In order to achieve the above purpose, the utility model discloses a following technical scheme realizes:
a hepatic portal blocking belt under a laparoscope comprises a hoop, a belt body and a tongue depressor; saw-toothed protrusions are arranged on one surface of the belt body; a clamp is fixed at one end of the belt body; a through groove is formed in the surface of the clamp; the inner surface of the through groove of the hoop is provided with a pressing tongue; the tongue depressor is an elastic pressing piece; a buckle is arranged on one surface of the pressure tongue corresponding to the sawtooth-shaped bulge of the belt body, and the buckle is matched with the bulge; when the tongue depressor is pressed down, the belt body only enters in a single direction.
Preferably, the other end edge of the belt body is of an arc-shaped structure.
The utility model provides a liver gate blocking area under peritoneoscope the utility model discloses beneficial effect has following several:
1. through the blocking belt, the liver valve can be quickly tightened when stopping bleeding, thereby achieving the purpose of stopping bleeding.
2. The inner side of the clamp is provided with a pressing tongue which is always pressed downwards under the normal state to prevent the blocking belt from loosening, and when the pressing tongue is lifted upwards, the blocking belt can be loosened to release the porta hepatis.
3. The blocking belt is disposable, but can be repeatedly used in the same operation, so that the time of the Pringle method operation is reduced.
Description of the drawings:
in order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
Fig. 1 is a schematic view of the overall structure of the present invention.
Fig. 2 is a schematic view of the back structure of the present invention.
Fig. 3 is a schematic side view of the present invention.
In the figure, a hoop 1, a band body 2, a pressure tongue 3, a buckle 4 and a bulge 5.
The specific implementation mode is as follows:
as shown in the figure, the laparoscopic porta hepatis blocking band comprises a hoop 1, a band body 2 and a tongue depressor 3; one surface of the belt body 2 is provided with saw-toothed bulges 5; one end of the belt body 2 is fixed with a clamp 1; the surface of the clamp 1 is provided with a through groove which is penetrated through the belt body 2 to form a hoop; the inner surface of the through groove of the clamp 1 is provided with a pressing tongue 3; the tongue 3 is an elastic pressing piece; one surface of the pressure tongue 3 corresponding to the sawtooth-shaped bulge 5 of the belt body 2 is provided with a buckle 4, and the buckle 4 is matched with the bulge 5; in consideration of preventing the sharp portion of one end of the band body 2 from easily pricking the organ during use, the other end edge of the band body 2 is formed in an arc-shaped configuration.
The above-mentioned fixing methods are all welded or screwed by means of the common technical means of those skilled in the art, if they are not separately described.
As shown, the operation process is as follows:
when the pressing tongue is used, the belt body 2 is clockwise wound around the hepatoduodenal ligament by a Pringle method, then the belt body 2 penetrates through the hoop 1, the belt body 2 is pulled out of the hoop 1 by using a laparoscopic forceps, and the belt body 2 can only enter in one direction at this time to play a role in tightening because the pressing tongue 3 is pressed downwards. The tightness of the bandage is adjusted according to the thickness of a blood vessel to be blocked, and the blood vessel at the hepatic portal part can be blocked. When the blocking time reaches 15 minutes, the bandage can be loosened by only lifting the pressing tongue 3 by using the laparoscopic forceps, and the blocking of the hepatic portal blood vessel is stopped. And if blocking is needed again, repeating the steps.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
