Problems solved by technology

However, the working power of the electric knife in the prior art is relatively low, and the operating efficiency is also relatively low. The reason is that the electric knife under high power operation will cause a large area of ​​overheating, thereby affecting other tissues of the human body.
Moreover, it is difficult for the electric knife to quickly and accurately control the heat of a large area of ​​overheating during use, which makes the operation inconvenient
[0003] The electric knife in the prior art also has the disadvantages of unsatisfactory heat conduction effect, small working temperature range, low energy conversion efficiency, and low energy storage density of the energy storage component. Moreover, the energy storage component of the existing electric knife cannot be disassembled. It makes the energy storage parts inconvenient to recycle, which makes it inconvenient to handle the electric knife after the operation

Embodiment 1

[0061] See Figure 1 to Figure 6. The heat dissipation structure of an integral heat pipe type electric knife in this embodiment is scissor-shaped, and includes two electrode ends 1, two heat pipes 2, two phase change energy storage rings 5 ​​and two knife handles 6. Two heat pipes 2 are hinged by the hinge shaft 3 and form a cross shape; the heat pipe 2 includes a cold end 21 of the heat pipe and a hot end 22 of the heat pipe, the cold end 21 of the heat pipe is connected to the front end of the handle 6, and the hot end 22 of the heat pipe is connected to the electrode end 1 Connection; the phase change energy storage ring 5 is detachably sleeved on the front end of the handle 6 . Because the heat dissipation structure is scissors-shaped and the structure design is reasonable, the heat dissipation structure of the integral heat pipe electric knife is easy to operate and flexible to use when cutting, coagulating, and burning tissues and organs in the human body during surger...

Embodiment 2

[0070] Embodiment 2 of the heat dissipation structure of the integral heat pipe type electric knife of the present invention, the difference between this embodiment and Embodiment 1 is that in this embodiment, the heat dissipation structure of the integral heat pipe type electric knife also includes nuts , the end of the energy storage ring groove 16 is provided with an external thread, and the nut is fixed on the end of the energy storage ring groove 16 through the external thread to fix the phase change energy storage ring 5 and limit the phase change energy storage ring 5 along the energy storage ring groove. 16 axial movement. Other structures and working principles of this embodiment are the same as those of Embodiment 1, and will not be repeated here.

Embodiment 3

[0072] See Figure 7 . Embodiment 3 of the heat dissipation structure of an integral heat pipe type electric knife of the present invention, the difference between this embodiment and Embodiment 1 is that in this embodiment, the liquid-absorbing core is set as a groove-type liquid-absorbing core 17, The grooved liquid-absorbing core 17 has the advantage of high thermal conductivity. Other structures and working principles of this embodiment are the same as those of Embodiment 1, and will not be repeated here.

Abstract

The invention relates to the technical field of surgical operating instruments, in particular to a heat dissipation structure of an integral heat pipe type electrotome and a manufacturing method thereof. The heat dissipation structure is in the shape of scissors and comprises two electrode terminals, two heat pipes, two phase-change energy storage rings and two knife handles, wherein the two heat pipes are hinged to each other through a hinged shaft in a cross mode; each heat pipe comprises a heat pipe cold end and a heat pipe hot end, the cold ends of the heat pipes are connected with the front ends of the knife handles, and the hot ends of the heat pipes are connected with the electrode terminals; the phase-change energy storage rings are arranged at the front ends of the knife handles in a detachable and sleeved mode. Due to the fact that the heat dissipation structure is in the shape of scissors, the heat dissipation structure of the integral heat pipe type electrotome is convenient to operate and flexible in use when used for conducting shearing, coagulation and ignition on tissue and organs of the human body during an operation, and then operation efficiency is improved; due to the fact that the phase-change energy storage rings are detachable, cyclic utilization of the phase-change energy storage rings can be achieved conveniently. The manufacturing method of the heat dissipation structure of the integral heat pipe type electrotome has the advantages of being simple and applicable to large-scale production.

Description

technical field [0001] The invention relates to the technical field of medical surgical instruments, in particular to a heat dissipation structure and a manufacturing method of an integral heat pipe type electric knife. Background technique [0002] Among medical devices, electric knife has replaced most of the mechanical scalpel and plays the role of cutting, coagulation, burning and so on in the operation. However, since the electric current of the electric knife directly acts on human tissue, the safety requirements for the electric knife are very strict. However, the working power of the electric knife in the prior art is relatively low, and the operating efficiency is also relatively low, because the electric knife operating under high power will cause a large area of ​​overheating, thereby affecting other tissues of the human body. Moreover, it is difficult for the electric knife to quickly and accurately control the heat of a large area of ​​overheating during use, t...
