The purpose of the specific embodiment is to provide an electric hook for laparoscopic surgery, which retains the function of the traditional electric hook, and meanwhile, a metal hook rod with a hollow structure is communicated with an external negative pressure suction device through an internal pipeline of a handle, so that the hook rod has the function of a negative pressure suction tube; thereby solving the problem that the electric hook and the negative pressure suction apparatus for the laparoscopic surgery are respectively of independent structures in the prior art.

Hereinafter, embodiments will be described with reference to the drawings. The embodiments described below do not limit the scope of the invention described in the claims. Further, the entire contents of the configurations shown in the following embodiments are not limited to those necessary as a solution of the invention described in the claims.

Referring to fig. 1-2, the present embodiment provides an electric hook for laparoscopic surgery, including a hook head 1, a hook rod 2 and a handle 4; the hook head 1 is made of a conductive metal material, the hook rod 2 is a metal rod with a hollow structure, an insulating layer is wrapped on the outer surface of the hook rod 2, and the insulating layer is preferably a TPU elastic flexible rubber tube in the embodiment because the material has the characteristics of high pressure and high temperature resistance, no toxicity, no harm, flame retardance, difficult aging and the like, when an electric hook is used for an electric hook operation, the condition that the electric hook is infected when being contacted with human organs or tissues can be effectively avoided, and meanwhile, the material is difficult to age, so that the service life of the electric hook can be greatly prolonged; the hook head 1 is fixedly connected with the first end of the hook rod 2, the hook head 1 and the hook rod 2 are of an integrally formed structure, the hook head 1 and the hook rod 2 can be made of silver, copper or aluminum, and the hook head 1 and the hook rod 2 are made of the materials, so that the hook head and the hook rod have certain hardness and supporting strength and excellent conductivity, and the hook rod 2 is electrically connected with an external power supply through a cable 3; handle 4 fixed connection is held at the second of hook stem 2, and the inside of handle 4 is linked together through pipeline 6 and external negative pressure aspirator, installs button 5 on handle 4 and the switch of button 5 can control the break-make of pipeline 6.

According to the arrangement, the electric hook for laparoscopic surgery keeps the function of the traditional electric hook, meanwhile, the metal hook rod 2 of the hollow structure is communicated with an external negative pressure suction device through the internal pipeline 6 of the handle 4, so that the hook rod 2 has the function of a negative pressure suction tube, when the surgical wound oozes blood and more seepage liquid in the anatomical separation process to influence the surgical field of vision, the pipeline 6 in the handle 4 is opened only by pressing the button 5 on the handle 4, the anatomical separation can be continued while suction, when the negative pressure suction function is not needed, the pipeline 6 in the handle 4 is closed only by pressing the button 5 on the handle 4, and the negative pressure suction tube and the electric hook are combined into a whole; thereby solving the problem that the electric hook and the negative pressure suction apparatus for the laparoscopic surgery are respectively of independent structures in the prior art.

As an optional implementation mode, a plastic hose 7 is fixedly connected to the handle 4, one end of the hose 7 is communicated with the pipeline 6 in the handle 4, and the other end of the hose 7 is communicated with an external negative pressure suction device. So arranged, the arrangement of the hose 7 provides a medium flow channel between the electric hook and the negative pressure suction apparatus, and the electric hook and the negative pressure suction apparatus are communicated.

As an alternative embodiment, the rear end of the handle 4 is provided with a circular opening 8. So set up, the cable conductor 3 in the handle 4 passes opening 8 and is connected with external power supply electricity.

In a more specific embodiment, the handle 4 is made of rubber, and the outer surface of the handle 4 is provided with corrugated protrusions 9 around the circumference. Due to the arrangement, the handle 4 is made of rubber, so that the experience degree of a worker in use is greatly improved, and the holding feeling of the worker on the handle 4 is more comfortable; the design of the corrugated bulges 9 on the handle 4 increases the friction force between the handle 4 and the palm of the worker, effectively reduces the slipping between the hand of the worker and the handle 4, and avoids the occurrence of errors in the laparoscopic surgery.

In a further embodiment, the protrusion 9 and the hose 7 are formed integrally with the handle 4 by injection molding. So set up, hose 7 and handle 4 formula structure as an organic whole, there is not the gap in the junction of hose 7 and handle 4, the condition that oozing blood or sepage leaked from the junction of hose 7 and handle 4 can not appear.

As an alternative embodiment, the first end of the hooking rod 2 is conical. So set up, the volume of the first end of 2 hook bars can effectually be reduced in the design of coniform, when carrying out laparoscopic surgery, the first end that has reduced 2 hook bars produces unnecessary contact with other organs in the abdominal cavity inside, avoids carrying out the fish tail to other organs in the abdominal cavity.

In a more specific embodiment, the hook stem 2, the conduit 6 and the hose 7 are all circular in cross-section. With the arrangement, the blood or the seepage in the abdominal cavity has certain viscosity, and when the blood or the seepage flows at the solid boundary, the blood or the seepage is blocked and interfered by the wall surface of the solid boundary, so that the flow resistance is formed, but the cross section area of the channel is circular, so that the stress of the liquid in the channel can be uniform, and the resistance of the liquid in the channel can be reduced to the greatest extent.

In a further embodiment, the radius of the hook stem 2, the pipe 6 and the hose 7 are all equal. So set up, when certain appeal was exerted to the negative pressure suction device, the radius of hook pole 2, pipeline 6 and hose 7 is all equal, can guarantee that the velocity of flow of the inside liquid of three is all the same.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
