Description

Technical Field

[0001] The utility model belongs to the technical field of surgical instruments, and in particular relates to a composite energy surgical cutting knife head which is a combination of a microwave hemostatic knife and an electric hook. Background Art

[0002] The microwave hemostatic cutting knife is a new type of solid tumor surgical resection instrument independently developed by my country. Compared with traditional surgical resection instruments, the microwave hemostatic cutting knife can greatly reduce surgical bleeding, reduce surgical risks, and improve surgical success rate. It plays a positive role in further expanding the field of surgery and promoting the development of departments.

[0003] The disadvantage of the current microwave hemostatic knife is that the hemostatic function is better than that of the ultrasonic knife, but the cutting function is inferior to that of the ultrasonic knife, and it is particularly difficult to separate blood vessels and fibrous tissues. Therefore, it is urgent to design a surgical cutting knife head with both outstanding cutting and hemostatic abilities. Utility Model Content

[0004] In view of the problems existing in the above-mentioned prior art, the utility model provides a composite energy surgical cutting blade head combining a microwave hemostatic knife and an electric hook, and specifically discloses the following technical solutions:

[0005] A composite energy surgical cutting blade head combining a microwave hemostat and an electric hook comprises a sleeve, wherein protective plates are respectively arranged on both sides of the front end of the sleeve, and a microwave hemostat and an electric hook are arranged on the front end of the sleeve between the two protective plates, the sleeve is filled with a filler for fixing the microwave hemostat and the electric hook, an electric wire and a microwave transmission line are penetrated through the rear part of the sleeve, the microwave hemostat is fixedly connected to the microwave transmission line, and the electric hook is fixedly connected to the electric wire, a water inlet hole is provided on the ventral surface of the microwave hemostat, a water outlet hole is provided on the back side of the microwave hemostat, and a water inlet pipe and a water outlet pipe are respectively arranged inside the sleeve, one end of the water inlet pipe extends to the interior of the microwave hemostat and is connected to the water inlet hole, and one end of the water outlet pipe extends to the interior of the microwave hemostat and is connected to the water outlet hole.

[0006] Furthermore, the microwave hemostatic knife, the electric hook and the two protective plates are all located on the same plane, the front end of the electric hook is flush with the front end of the microwave hemostatic knife and exceeds the front end of the protective plate close to the electric hook.

[0007] Furthermore, the microwave transmission line is a copper wire with an insulating sheath.

[0008] Furthermore, the filler is epoxy resin glue.

[0009] Furthermore, the vertical distance between the water inlet and the tip of the microwave hemostatic knife is smaller than the vertical distance between the water outlet and the tip of the microwave hemostatic knife.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] In the utility model, a microwave hemostatic knife and an electric hook are combined to form a composite energy surgical cutting knife head, so that the functions and advantages of the microwave hemostatic knife and the electric hook are combined, and the use is more convenient and efficient;

[0012] The ventral and dorsal surfaces of the microwave hemostatic knife are respectively provided with a water inlet and a water outlet. When the microwave hemostatic knife is used for surgery, water flows out of the water outlet to flush the tissue, while the water inlet can suck out blood and water, thereby providing a clear field of vision for the surgery.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Reference Figure 1-3A composite energy surgical cutting blade head combining a microwave hemostatic knife and an electric hook comprises a sleeve 1, the sleeve 1 can be made of stainless steel, and protective plates 4 are respectively arranged on both sides of the front end of the sleeve 1, and the protective plates 4 are two protrusions left after two U-shaped grooves are dug out of the front part of the sleeve 1. The front end of the sleeve 1 is located between the two protective plates 4 and is provided with a microwave hemostatic knife 2 and an electric hook 3. The sleeve 1 is filled with a filler 11 for fixing the microwave hemostatic knife 2 and the electric hook 3, and an electric wire is passed through the rear part of the sleeve 1 5 and a microwave transmission line 6, the microwave hemostatic knife 2 is fixedly connected to the microwave transmission line 6, the electric hook 3 is fixedly connected to the electric wire 5, a water inlet hole 7 is provided on the ventral surface of the microwave hemostatic knife 2, a water outlet hole 8 is provided on the back surface of the microwave hemostatic knife 2, a water inlet pipe 9 and a water outlet pipe 10 are respectively provided inside the sleeve 1, one end of the water inlet pipe 9 extends to the inside of the microwave hemostatic knife 2 and is communicated with the water inlet hole 7, and one end of the water outlet pipe 10 extends to the inside of the microwave hemostatic knife 2 and is communicated with the water outlet hole 8.

[0019] In this embodiment, a microwave hemostatic knife 2 and an electric hook 3 are provided at the front end of the sleeve 1. Medical personnel can select appropriate knives for operation according to actual conditions. The electric conductor 5 can provide electrical energy to the electric hook 3, and the microwave transmission line 6 is used to transmit microwaves. When the microwave hemostatic knife 2 is used for operation, the water outlet 8 on the back of the microwave hemostatic knife 2 can spray water to flush the tissue, and the water inlet 7 on the ventral side of the microwave hemostatic knife 2 can absorb blood and water, thereby ensuring a clear surgical field of view.

[0020] When the cutter head in this embodiment is actually used, its rear end is usually connected to a cutter rod and a handle, thereby forming a structure similar to a screwdriver, so that medical personnel can use it conveniently. The electrical conductor 5, the microwave transmission line 6, the water inlet pipe 9 and the water outlet pipe 10 pass through the cutter rod and the handle in sequence and are finally connected to the corresponding energy device or drive device.

[0021] In this embodiment, the microwave hemostatic knife 2, the electric hook 3 and the two protective plates 4 are all located on the same plane. The front end of the electric hook 3 is flush with the front end of the microwave hemostatic knife 2, so that medical personnel can select one of them for operation. The front end of the electric hook 3 exceeds the front end of the protective plate 4 close to the electric hook 3, thereby avoiding the protective plate 4 from hindering the use of the electric hook 3.

[0022] In this embodiment, the microwave transmission line 6 is a copper wire with an insulating sheath.

[0023] In this embodiment, the filler 11 is made of epoxy resin glue, which can effectively fix the microwave hemostatic knife 2 and the electric hook 3 after curing, and has an insulating effect.

[0024] In this embodiment, the vertical distance between the water inlet hole 7 and the tip of the microwave hemostatic knife 2 is smaller than the vertical distance between the water outlet hole 8 and the tip of the microwave hemostatic knife 2, thereby facilitating timely extraction of blood through the water inlet hole 7.

[0025] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
