Problems solved by technology

However, it is difficult to control the heat conduction and diffusion process in the tissue when welding with such electrodes, and the thermal damage to the tissue is relatively serious when a certain welding strength is reached.
In addition, the inversion of the anastomosis method is likely to cause narrowing of the official lumen, and the continuous stimulation of the lumen contents also affects the healing of the anastomotic stoma in the welding area, which is not conducive to the recovery of tissue structure and function

Embodiment

[0037] A linkage type pressure controllable tissue welding electrode, such as figure 1 As shown, it includes a controllable linkage pressure applying device, a negative electrode, and a positive electrode set on the controllable linkage pressure applying device. The controllable linkage pressure applying device is as follows Figure 4 As shown, it includes a moving main shaft 9 and a casing 8 sleeved outside the moving main shaft 9. The inside of the casing 8 is processed with a funnel-shaped cavity. The moving main shaft 9 is provided with threads, and the casing 8 is matched with the moving main shaft 9 through threads. , by rotating the housing 8 to make the housing 8 move along the axial direction of the moving main shaft 9 . The central position of the moving main shaft 9 is provided with an axial through hole for the negative electrode to pass through, and the side wall of the moving main shaft 9 is also provided with a through bar-shaped groove along the radial directio...

Abstract

A linkage pressure controllable tissue welding electrode and an application are disclosed. The welding electrode comprises a controllable interlocking pressure applying device, a negative electrode, and a positive electrode provided on the controllable linkage pressure applying device, The controllable linkage pressure applying device comprises a moving spindle (9) and a housing (8) sleeved on theexterior of the moving spindle (9). The moving spindle (9) is centrally provided with an axial through hole through which a negative electrode passes. A radially penetrating strip groove is also arranged on the side wall of the moving spindle (9), and a slider (3) is arranged in the strip groove. Compared with the prior art, the welding electrode of the invention can anastomose the lumen tissue,and can realize the accurate control of the pressing pressure, meanwhile, the energy input to the positive electrode is adjusted independently, and the heat conduction and diffusion in the tissue arecontrolled, which is beneficial to reducing the heat damage of the tissue, promoting the healing of the anastomotic stoma and improving the quality of the operation.

Description

technical field [0001] The invention relates to an electrosurgical medical instrument, in particular to a linkage type pressure-controllable tissue welding electrode and its application. Background technique [0002] Gastrointestinal anastomosis is an important link in gastrointestinal surgery. The anastomosis process is to resect the diseased (tumor) intestinal segment, and then join the remaining intestinal segment to restore the continuity and integrity of its structure and function. The effect of anastomosis is directly related to the quality of the operation and the postoperative recovery of the patient. [0003] Commonly used methods of anastomosis include traditional manual needle and thread suture and mechanical stapler anastomosis. Compared with manual needle and thread suture, stapler anastomosis simplifies the operation process, shortens the operation time, and realizes efficient and rapid tissue anastomosis, making some operations that were difficult to achieve...
