(first embodiment)
Fig. 1 to 3 show a deep electrode assembly according to a first embodiment of the present application.
The deep electrode assembly includes a catheter 1, a guide screw assembly 2, a wire divider 3, a plug 4, a connecting wire 5, and a protective sheath 6. The outer peripheral surface of the catheter 1 is provided with a contact 11, and a hollow area inside the catheter 1 is provided with a wire extending in the axial direction of the catheter 1. The wire is electrically connected to the contact 11 through the outer peripheral wall of the catheter 1. The wire divider 3 has a rectangular parallelepiped structure, and one end of the guide tube 1 is connected to the central portion of one surface of the wire divider 3. One end of the connection wire 5 is connected to a central portion of the other surface of the splitter 3 which faces the one surface, and the other end of the connection wire 5 is connected to the plug 4.
The lead screw assembly 2 includes a lead screw 21 and a nut 22. A nut 22 is fitted over the end of the lead screw 21 and is threadedly engaged with the lead screw 21. The guide screw 21 is formed with a through hole extending along an axial direction thereof. The guide tube 1 is inserted through the through hole from the end of the guide screw 21 where the nut 22 is mounted, so that the guide tube 1 penetrates the guide screw 21. The portion of the pipe 1 between the nut 22 and the wire divider 3 is prone to bending and stretching and thus serves as the covered portion 12 in this application.
The protective sheath 6 comprises a covering 61, a first connection 62 and a transition 63. The covering portion 61 is a hollow rotating body having both ends open. The first connection portion 62 includes a first sidewall 621 and a first end wall 622. The first sidewall 621 forms a cylindrical structure having a circular cross-section. One axial end of the first sidewall 621 is fixed to the other axial end of the covering portion 61, and the first sidewall 621 is disposed coaxially with the covering portion 61. The first end wall 622 is fixed to the other axial end of the first side wall 621 and extends toward the radially inner side. The transition portion 63 is located between the covering portion 61 and the first connecting portion 62, and one axial end of the first sidewall 621 and the other axial end of the covering portion 61 are fixedly connected to the transition portion 63. The cross-sectional area of the transition portion 63 gradually increases toward the first connection portion 62, so that the transition portion 63 is formed in a horn shape. The opening 6a extends through the covering 61, the first connecting portion 62 and the transition portion 63, and the opening 6a at the covering 61, the first connecting portion 62 and the transition portion 63 communicates between the inside of the protective sheath 6 and the outside of the protective sheath 6, so that the protective sheath 6 can be opened from the opening 6 a.
During surgery, the catheter 1 is passed through the guide screw 21 to introduce the electrode into the interior of the skull of the patient. When the catheter 1 reaches the proper position, the knob nut 22 presses against the washer between the guide screw 21 and the nut 22. The compressed washer expands in the direction of the catheter 1, fixing the catheter 1 to the guide screw 21, and the length of the covered portion 12 does not change. At this time, the protective cover 6 is opened from the opening 6a and fitted over the covered portion 12 and the nut 22. The coating portion 61 coats the outer peripheral surface of a part of the coated portion 12. The first side wall 621 of the first connecting portion 62 covers the outer peripheral surface of the nut 22, and the first end wall 622 of the first connecting portion 62 covers the end surface of the nut 22. The guide screw 21 projects through the first end wall 622 to the outside of the protective sheath 6. In this way, the covering portion 61 covers a part of the covered portion 12, so that the covered portion 12 is not easily bent at the covered part. The covering portion 61 is fixed to the first connecting portion 62, and the first connecting portion 62 is connected to the nut 22, so that the root portion of the covered portion 12 close to the nut 22 is not easily bent. The protective sheath 6 effectively reduces the risk of damage to the wires inside the catheter 1 due to bending of the catheter 1.
Furthermore, the first end wall 622 covers the end face of the nut 22, so that the protective sheath 6 is fixed relative to the catheter 1 in the axial direction of the catheter 1, preventing the protective sheath 6 from moving. The protective sheath 6 can be opened from the opening 6a so that the protective sheath 6 can be sheathed on the catheter 1 at any time during the operation, and the use of the protective sheath 6 has higher flexibility. The transition portion 63 is formed in a trumpet shape, so that the covering portion 61 and the first connecting portion 62 smoothly transition, and the risk of bending of the root portion of the covered portion 12 close to the nut 22 is further reduced.
After the protective cover 6 is mounted, a locking device can be added on the outside of the protective cover 6 to close the opening 6a, so that the protective cover 6 is tightly attached to the covered part 12 and the nut 22. In particular, the locking means may be a medical adhesive tape or elastic tape, which may be wound around the outside of the protective sheath 6.
The protective sheath 6 may have a uniform wall thickness. The protective sheath 6 may have a wall thickness in the range of 0.1mm to 5 mm. The width of the opening 6a may be 0.01mm to 2mm when the protective cover 6 is not covered with the nut 22 and the covered portion 12.
The protective sheath 6 may be made of rubber. In particular, the protective sheath 6 may be made of silicone rubber.
