Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a rotating tail wire and an operating method thereof. Background Art

[0002] When the electrode lead in the prior art connects two electrode ends, if one end needs to be rotated, the other end will often become knotted and entangled. For example, the SelectSecure 3830 pacing electrode lead is a solid electrode lead, which is currently mainly used for pacing in the His bundle and left bundle branch area. During the operation, the surgeon needs to continuously rotate the 3830 pacing electrode lead so that the implanted end of the electrode lead can be rotated into the patient's heart.

[0003] During the process of rotating the implant end, the pacemaker programmer needs to monitor the changes in electrode impedance at any time. In the current operation, the cathode and anode of the electrode end of the 3830 pacing electrode lead are fixed by crocodile clips and connected to the pacemaker programmer through test lines. When the 3830 pacing electrode lead is rotated, the crocodile clip test line will rotate synchronously, causing the test line to be entangled and knotted. Therefore, the connection between the crocodile clip test line and the tail end of the 3830 pacing electrode must be repeatedly disconnected, and continuous impedance monitoring cannot be achieved. The characteristics of the 3830 electrode determine that if continuous impedance monitoring cannot be implemented, a certain proportion of excessive rotation will inevitably occur, causing the electrode to rotate too deeply and cause ventricular septal perforation. In order to avoid rotating too deeply at one time, the tail line needs to be repeatedly disconnected and untwisted, which will extend the operation time and increase the surgical risk. Summary of the invention

[0004] The purpose of the present invention is to provide a rotating tail line and an operating method thereof, so as to solve the problems mentioned in the background technology.

[0005] In order to achieve the above technical objectives, the technical solution adopted by the present invention is as follows:

[0006] A rotating tail line comprises a shell, wherein a slip ring rotating drum is fixedly arranged inside the shell, and a joint mechanism connected to the slip ring rotating drum is arranged outside the shell;

[0007] The connector mechanism includes a conductive wire assembly and an electrode interface assembly. The conductive wire assembly is located in the shell near the probe side. The conductive wire assembly passes through the slip ring drum and is connected to the electrode interface assembly. The electrode interface assembly is rotationally connected to the slip ring drum and extends out of the shell. The electrode interface assembly is connected to an external element.

[0008] The electrode interface assembly comprises a transmission shaft and a plug-in terminal. The transmission shaft rotates through the slip ring drum and is rotationally connected thereto. The plug-in terminal is arranged outside the housing and is connected to the transmission shaft.

[0009] The plug-in terminal includes an electrode interface shell, an anode compression spring conductive sheet, a cathode compression spring conductive sheet and a compression spring wrench. The electrode interface shell is connected to the shell, and the electrode interface shell has an inner cavity. The anode compression spring conductive sheet is arranged on the lower side of the inner cavity, and the cathode compression spring conductive sheet is arranged between the electrode interface shell and the shell. The compression spring wrench is arranged on the upper side of the electrode interface shell and corresponds to the position of the anode compression spring conductive sheet. The electrode interface shell has a socket that matches the anode compression spring conductive sheet and the cathode compression spring conductive sheet.

[0010] The conductive wire assembly includes an anode conductive wire and a cathode conductive wire, the electrode ends of the anode conductive wire and the cathode conductive wire are fixed in a shell, and the wiring harnesses of the anode conductive wire and the cathode conductive wire pass through a transmission shaft and are respectively connected to the anode compression spring conductive sheet and the cathode compression spring conductive sheet.

[0011] The compression spring wrench is connected to the electrode interface housing in an up-and-down damping sliding manner.

[0012] A method for operating a rotating tail line, the specific steps are as follows:

[0013] The external element is a 3830 pacemaker. After the probe enters the body during the operation, the compression spring wrench at the plug-in end of the rotating tail wire is lifted, and the electrode lead electrode end of the 3830 pacemaker is inserted into the socket of the rotating tail wire, so that the cathode and anode of the electrode lead electrode end of the 3830 pacemaker are in close contact with the anode compression spring conductive sheet and cathode compression spring conductive sheet of the rotating tail wire respectively, and the compression spring wrench is pressed down to make the anode compression spring conductive sheet clamp the electrode lead electrode end of the 3830 pacemaker, and then the 3830 pacemaker electrode lead is connected to the test line, and the test line on the rotating tail wire is connected to the pacemaker programmable tester, and the pacemaker programmable tester is turned on. The 3830 pacemaker electrode lead can be rotated uninterruptedly by holding the handle end of the rotating tail wire, so as to realize real-time electrode impedance monitoring throughout the whole process, avoid entanglement of the test line, and realize uninterrupted implantation process until the electrode is safely in place and successfully implanted.

[0014] Compared with the prior art, the present invention has at least the following advantages:

[0015] The invention provides a rotating tail line and an operating method. The rotating tail line prevents knotting and entanglement at the tail line by arranging a slip ring drum, a conductive wire assembly and an electrode interface assembly, realizes uninterrupted operation, and ensures work efficiency and stability of current and resistance during operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 2 It is a structural cross-sectional view of the present invention.

[0019] Figure 3 This is a schematic diagram of the structure of the present invention after removing the shell.

[0022] like Figure 1-3 The rotary tail line shown comprises a housing 1, a slip ring drum 2 is fixedly arranged inside the housing 1, and a joint mechanism connected to the slip ring drum 2 is arranged outside the housing 1;

[0023] The connector mechanism includes a conductive wire assembly and an electrode interface assembly. The conductive wire assembly is located in the shell 1 near the probe side. The conductive wire assembly passes through the slip ring drum 2 and is connected to the electrode interface assembly. The electrode interface assembly is rotationally connected to the slip ring drum 2 and extends out of the shell 1. The electrode interface assembly is connected to external components.

[0024] During surgical operation, the conductive wire assembly is connected to the front probe, the rear side of the conductive wire assembly is connected to the electrode interface assembly, and the test line of the external component is connected to the electrode interface assembly, so that the signal can be monitored by inserting the probe into the patient's lesion. The probe needs to be rotated during the insertion process. To avoid the wiring harness from being entangled, since the electrode interface assembly is rotatably connected to the slip ring drum 2 and extends out of the shell 1, the external test line can be fixed first, and then the electrode interface assembly is rotated to untangle the conductive wire assembly in the shell 1, and then the electrode interface assembly and the shell 1 are fixed, and then the external test line is rotated to untangle. This method of fixing different components separately and then untangling them step by step can ensure continuous monitoring of the wiring harness during surgery, and there is no need to deliberately untie the connection to avoid wiring harness entanglement.

[0025] The electrode interface assembly includes a transmission shaft 3 and a plug-in terminal. The transmission shaft 3 rotates through the slip ring drum 2 and is rotationally connected thereto. The plug-in terminal is arranged outside the shell 1 and is connected to the transmission shaft 3. The transmission shaft 3 can rotate relative to the slip ring to drive the electrode interface assembly to rotate to achieve an adjustment effect.

[0026] The plug-in terminal includes an electrode interface shell 4, an anode compression spring conductive sheet 41, a cathode compression spring conductive sheet 42 and a compression spring wrench 43.

The anode compression spring conductive sheet 41 is arranged at the lower side of the inner cavity 44. The cathode compression spring conductive sheet 42 is arranged between the electrode interface shell 4 and the shell 1. The compression spring wrench 43 is arranged at the upper side of the electrode interface shell 4 and corresponds to the position of the anode compression spring conductive sheet 41. The electrode interface shell 4 has a socket 45 that matches the anode compression spring conductive sheet 41 and the cathode compression spring conductive sheet 42.

[0027] The electrode interface housing 4 is used to protect the internal components, the anode compression spring conductive sheet 41 and the cathode compression spring conductive sheet 42 are used to cooperate with the external wiring harness and the conductive wire assembly to connect the signal and power supply, and the compression spring wrench 43 is used to tighten the electrode lead electrode end of the 3830 pacemaker inserted into the socket 45, and other fastening methods such as levers, spring clips, etc. can also be used.

[0028] The conductive wire assembly includes an anode conductive wire 5 and a cathode conductive wire 51, the electrode ends of the anode conductive wire 5 and the cathode conductive wire 51 are fixed in the shell 1, and the wiring harnesses of the anode conductive wire 5 and the cathode conductive wire 51 pass through the transmission shaft 3 and are respectively connected to the anode compression spring conductive sheet 41 and the cathode compression spring conductive sheet 42; in this way, after the anode conductive wire 5 and the cathode conductive wire 51 are relatively fixed, they can not only play an effective signal and power transmission role, but also can achieve the effect of unwinding by rotating the parts as needed.

[0029] The compression spring wrench 43 is connected to the electrode interface housing 4 in an up-and-down damping sliding manner.

[0030] A method for operating a rotating tail line, the specific steps are as follows:

[0031] The external component is a 3830 pacemaker. After the probe enters the body during the operation, lift the compression spring wrench 43 at the plug-in end of the rotating tail wire, insert the electrode lead electrode end of the 3830 pacemaker into the socket 45 of the rotating tail wire, make the cathode and anode of the electrode lead electrode end of the 3830 pacemaker tightly contact with the anode compression spring conductive sheet 41 and cathode compression spring conductive sheet 42 of the rotating tail wire respectively, press down the compression spring wrench 43, make the anode compression spring conductive sheet 41 clamp the electrode lead electrode end of the 3830 pacemaker, then connect the 3830 pacemaker electrode lead to the test line, connect the test line on the rotating tail line to the pacemaker programmable tester, turn on the pacemaker programmable tester, hold the handle end of the rotating tail line, and rotate the 3830 pacemaker electrode lead continuously to realize real-time electrode impedance monitoring throughout the process, avoid entanglement of the test line, and realize uninterrupted implantation until the electrode is safely in place and successfully implanted.
