Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical devices, and more specifically relates to a laparoscopic drainage device with an electric knife head. Background Art
[0002] Currently, the electrosurgical unit commonly used in laparoscopic surgery uses heat generated by high-frequency current to cut tissue. Traditionally, surgeons use one electrosurgical unit for cutting and another drainage tube to remove smoke and fluid produced during cutting. This process requires two separate instruments, complicating the procedure and, in some cases, affecting clarity and reducing surgical accuracy. Therefore, a laparoscopic Peng's electrosurgical unit is needed that reduces instrument changes, facilitates operation, and improves efficiency. Utility Model Content
[0003] The technical problem to be solved by the present invention is to provide a laparoscopic drainage device with an electric knife head, which can meet the needs of reducing instrument replacement, facilitating operation and improving efficiency.
[0004] The utility model discloses a laparoscopic drainage device with an electric knife head, comprising a tube body, a tube mouth, an electric knife head, a valve, a connecting port and an electric coagulation wire. The tube mouth is arranged at one end of the tube body, and a wall slit is provided on the tube wall of the tube mouth. The tail of the electric knife head is fixedly connected to the wall slit, and the head extends out of the tube mouth. One end of the electric coagulation wire passes through the tube body, extends into the wall slit and is connected to the electric knife head, and the other end is connected to an external electric coagulation machine. The valve is fixedly connected to a side of the middle section of the tube body away from the tube mouth. The valve is adjusted to control the smoking flow of the tube body. The connecting port is arranged at the end of the tube body away from the tube mouth. A cannula is provided at the head of the negative pressure drainage bottle, and the cannula is inserted into the connecting port so that the negative pressure drainage bottle is connected to the tube body.
[0005] As a further improvement of the present invention, the tube body is provided with several groups of smoking holes at one end near the tube mouth. The smoking holes are evenly distributed along the radial circumference of the tube body to avoid blockage caused by a single smoking hole diameter. Even if some smoking holes are blocked, the other smoking holes can still work normally, which helps to maintain a good smoking effect.
[0006] As a further improvement of the present invention, each group of smoking holes uses holes of different diameters to adapt to the flow of different liquids and gases.
[0007] As a further improvement of the present invention, the tail of the cutter head is in an arc shape that matches the tube body, and the cross-section is elliptical to meet the connection requirements between the tube body and the electric cutter head and increase the connection stability.
[0008] As a further improvement of the present invention, a section of the tube body close to the tube mouth is set to be conical, and the diameter of the cone neck is smaller than the diameter of the tube body at both ends, which promotes high-speed flow of gas, thereby forming turbulence, increasing gas flow rate, and increasing smoking efficiency.
[0009] As a further improvement of the present invention, a replaceable filter is provided in the connection port to filter the drainage liquid, prevent foreign matter from entering the negative pressure drainage bottle and ensure the purity of the drainage liquid.
[0010] Compared with the existing technology, the beneficial effects of the present invention are: the electric knife head and the smoking tube are integrated into one device, the steps of replacing the equipment are optimized, the operation is convenient and the efficiency is improved; the smoking holes are evenly distributed along the radial circle of the tube body to avoid blockage caused by a single smoking hole diameter; each group of smoking holes uses holes of different diameters to adapt to the flow of different liquids and gases; the tail of the knife head is an arc that matches the tube body, and the cross-section shape is elliptical to adapt to the connection requirements between the tube body and the electric knife head, and increase the connection stability; a section of the body close to the tube mouth is set to be conical, and the diameter of the cone neck is smaller than the diameter of the tube body at both ends, which promotes high-speed flow of gas, thereby forming turbulence, increasing gas flow rate, and increasing smoking efficiency.

[0019] Specific embodiment 1: Please refer to Figures 1-6The utility model relates to a laparoscopic drainage device with an electric knife head, comprising a tube body 1, a tube mouth 2, an electric knife head 3, a valve 4, a connecting port 5 and an electric coagulation wire 6. The tube mouth 2 is arranged at one end of the tube body 1, and a wall slit is provided on the tube wall of the tube mouth 2. The tail of the electric knife head 3 is fixedly connected to the wall slit, and the head extends out of the tube mouth 2. One end of the electric coagulation wire 6 passes through the tube body 1 and extends into the wall slit to be connected with the electric knife head 3, and the other end is connected to an external electric coagulation machine. The valve 4 is fixedly connected to the side of the middle section of the tube body 1 away from the tube mouth 2. The valve 4 is adjusted to control the smoking flow of the tube body 1. The connecting port 5 is arranged at the end of the tube body 1 away from the tube mouth 2. A cannula is provided at the head of the negative pressure drainage bottle 7, and the cannula is inserted into the connecting port 5 so that the negative pressure drainage bottle 7 is connected to the tube body 1.
[0020] In a further embodiment, Figure 4-Figure 5 As shown, the pipe body 1 is provided with a plurality of groups of smoking holes 11 at one end near the pipe mouth 2. The smoking holes 11 are evenly distributed along the radial direction of the pipe body 1. Each group of smoking holes 11 has a different diameter to adapt to the flow of different liquids and gases, avoiding blockage caused by the diameter of a single smoking hole 11. Even if some smoking holes 11 are blocked, the other smoking holes 11 can still work normally, which helps to maintain a good smoking effect.
