The guide assembly 1 comprises a handle 11 and a guide piece 12, the guide piece 12 is slidably connected with the handle 11, and the guide piece 12 can slide towards or away from the handle 11.

[0040] One end of the electrode piece 2 is detachably connected with the handle 11, and the other end of the electrode piece 2 is detachably connected with the guide piece 12. When the two ends of the electrode piece 2 are connected with the handle 11 and the guide piece 12 respectively, the electrode piece 2 can be sent into the brain lesion through the handle 11 and the guide piece 12 to treat the brain. The detachable connection between the electrode piece 2 and the guide piece 2 can be interference fit or threaded connection; the detachable connection between the electrode piece 2 and the handle 11 can be fixed by using a rope that can be loosened, and the rope is loosened or tightened to realize the detachment.

[0041] The control assembly 3 comprises a control piece 31, the control piece 31 is movably arranged on the handle 11 and connected with the guide piece 12, and when the control piece 31 moves relative to the handle 11, the guide piece 12 can be driven to move towards the handle 11, so that the guide piece 12 is separated from the electrode piece 2.

[0042] In the embodiment, when the electrode piece 2 needs to be sent into the brain lesion, the handle 11 and the guide piece 12 can be connected with the electrode piece 2 to support the electrode piece 2, so that the electrode piece 2 is conveniently sent into the brain lesion through the handle 11 and the guide piece 12 to treat the brain. When the electrode piece 2 reaches the brain lesion, one end of the electrode piece 2 can be detached from the guide piece 12, and the other end of the electrode piece 2 can be moved relative to the handle 11 by controlling the control piece 31, so that the guide piece 12 is driven to move towards the handle 11, thereby the guide piece 12 is separated from the other end of the electrode piece 2, the electrode piece 2 can be left in the brain, and the handle 11 and the guide piece 12 can be withdrawn from the brain, so that the handle 11 and the guide piece 12 do not injure the normal tissue of the brain.

[0043] In one of the embodiments, please refer to Figure 4The control assembly 3 further comprises a linkage mechanism 32 connecting the control member 31 and the guide member 12, the control member 31 being slidingly connected to the handle 11, and the control member 31 being capable of driving the linkage mechanism 32 to move when sliding, so as to drive the guide member 12 to slide towards the handle 11, and thus the guide member 12 to be separated from the electrode member 2.

[0044] In the embodiment, the control member 31 is slidingly arranged on the handle 11 and capable of controlling the guide member 12 to be separated from the electrode member 2 when sliding relative to the handle 11. In other embodiments, the control member 31 can be rotatably arranged on the handle 11 and capable of controlling the guide member 12 to be separated from the electrode member 2 when rotating relative to the handle 11.

[0045] In addition, the control member 31 of the embodiment indirectly connects the guide member 12 through the linkage mechanism 32 and indirectly controls the guide member 12 to slide to be separated from the electrode member 2. In other embodiments, the linkage mechanism 32 can be omitted, and the control member 31 can be directly connected to the guide member 12, for example, the control member 31 and the guide member 12 can be welded or integrally formed, so that the guide member 12 can be driven to slide to be separated from the electrode member 2 when the control member 31 slides.

[0046] In one of the embodiments, please refer to Figure 4 The linkage mechanism 32 comprises a linkage gear 321, a first rack 322 and a second rack 323, the linkage gear 321 being rotatably connected to the handle 11, the first rack 322 being engaged with the linkage gear 321 and connected to the guide member 12, and the second rack 323 being engaged with the linkage gear 321 and connected to the control member 31.

[0047] In the embodiment, the linkage mechanism 32 drives the guide member 12 to slide towards the handle 11 through gear engagement transmission. Specifically, the sliding direction of the control member 31 is parallel to the sliding direction of the guide member 12 in the embodiment, and the control member 31 can be pressed to slide towards the guide member 12, the control member 31 drives the first rack 322 to move, the first rack 322 drives the linkage gear 321 to rotate through engagement, the linkage gear 321 drives the second rack 323 to move towards the control member 31 through engagement, and the second rack 323 drives the guide member 12 to slide towards the handle 11. In the embodiment, the control member 31 only needs to be pressed to control the guide member 12 to slide towards the handle 11 to be separated from the electrode member 2, and the operation is simple.

[0048] Further, please refer to Figure 4The linkage mechanism 32 further comprises a first elastic member 324, which is connected to the handle 11 and the control member 31. The control member 31 can press against the first elastic member 324 when the sliding drive guide member 12 slides towards the handle, so as to drive the first elastic member 324 to accumulate elastic force. The first elastic member 324 can release the elastic force to drive the control member 31 to slide back to the original position when the external force on the control member 31 is removed.

[0049] In the embodiment, the control member 31 can compress the first elastic member 324 to accumulate elastic force when the control member 31 slides towards the guide member 12 under the action of the external force. At this time, the guide member 12 is separated from the electrode member 2. The control member 31 can be released to cancel the external force on the control member 31 when the guide member 12 is far away from the electrode member 2 during the process of withdrawing from the brain. The first elastic member 324 releases the elastic force to drive the control member 31 to slide away from the guide member 12, so as to reset the control member 31. The control member 31 drives the guide member 12 to slide away from the handle 11 through the second rack 323, the linkage gear 321 and the first rack 322 in sequence, so as to prepare for the secondary use. In addition, the first elastic member 324 in the embodiment is a spring. The second rack 323 is arranged in the spring before being connected to the control member 31, which does not affect the use of the spring.

[0050] In one of the embodiments, referring to Figure 4 and Figure 5 , the handle 11 has a first flange 111 and a second flange 112, which are spaced apart to form a limiting space 113. The linkage gear 321 is located in the limiting space 113. The first rack 322 is located between the linkage gear 321 and the first flange 111 and abuts against the first flange 111. The second rack 323 is located between the linkage gear 321 and the second flange 112 and abuts against the second flange 112.

[0051] In the embodiment, the limiting space 113 is formed by the first flange 111 and the second flange 112, so that the first rack 322 can be attached to the first flange 111 during the reciprocating movement, and the first rack 322 can stably reciprocate. Similarly, the second rack 323 can be attached to the second flange 112 during the reciprocating movement, and the second rack 323 can stably reciprocate, so as to stably drive the guide member 12 to slide away from the electrode member 2.

[0052] In one of the embodiments, referring to Figure 6 , Figure 6Another embodiment of the linkage mechanism 32 is shown. The linkage mechanism 32 of this embodiment comprises a first hook member 325, a second hook member 326 and a second elastic member 327, the first hook member 325 connecting the control member 31 and the guide member 12, the second hook member 326 slidingly connecting the handle 11 and sliding in a direction perpendicular to the sliding direction of the guide member 12, the second elastic member 327 connecting the handle 11 and the second hook member 326, the control member 31 being able to drive the guide member 12 to slide towards the handle 11 through the first hook member 325 when sliding, the first hook member 325 being able to drive the second hook member 326 to slide and be engaged with the second hook member 326 when sliding, and simultaneously drive the second elastic member 327 to be stretched to accumulate elastic force.

[0053] In this embodiment, the sliding direction of the first hook member 325 is perpendicular to the sliding direction of the second hook member 326. Please refer to Figure 7 , the first hook member 325 has a first inclined surface 328, and the second member 326 has a second inclined surface 329, the control member 31 being able to drive the guide member 12 to slide towards the handle 11 to disengage the electrode member 2 when sliding towards the second hook member 326. In this process, the first hook member 325 slides towards the second hook member 326, and the first inclined surface 328 is able to press against the second inclined surface 329 to drive the second hook member 326 to slide along Figure 6 the right side as shown, and the second elastic member 327 is stretched by the second hook member 326 to accumulate elastic force; when the first hook member 325 is misaligned with the second hook member 326, the second elastic member 327 releases a small amount of elastic force to retract, and drives the second hook member 326 to be engaged with the first hook member 325 to lock the first hook member 325, so as to prevent the guide member 12 from sliding away from the handle 11.

[0054] Further, please refer to Figure 8 , the linkage mechanism 32 further comprises a third elastic member 320, the third elastic member 320 connecting the handle 11 and the first hook member 325, the third elastic member 320 being able to accumulate elastic force when the first hook member 325 drives the guide member 12 to slide towards the handle 11, and being able to release elastic force to drive the guide member 12 to reset when the first hook member 325 is disengaged from the second hook member 326.

[0055] In the embodiment, the third elastic member 320 is added to the last embodiment to reset the control member 31 for secondary use, and to make the first hook member 325 and the second hook member 326 more stable. When the control member 31 slides towards the second hook member 326, the third elastic member 320 is compressed to accumulate elastic force. When the first hook member 325 and the second hook member 326 are clamped, the third elastic member 320 is still in the state of being compressed to accumulate elastic force. At this time, the third elastic member 320 drives the first hook member 325 to have a tendency to move away from the second hook member 326 by elastic force, so that the first hook member 325 and the second hook member 326 are clamped more tightly and stably. When the control member 31 needs to be reset, an external force can be applied to the second hook member 326 to drive the second hook member 326 to slide to the right along the direction indicated by the arrow in the figure until the second hook member 326 is separated from the first hook member 325. The third elastic member 320 releases the elastic force to drive the first hook member 325 to slide away from the second hook member 326, and the first hook member 325 drives the control member 31 to slide down to reset. Figure 6

[0056] In one of the embodiments, the control member 31 is rotationally connected to the handle 11 and can drive the guide member 12 to move towards the handle 11 when it rotates.

[0057] In the embodiment, another way of movably arranging the control member 31 on the handle 11 is shown. The control member 31 is movably arranged on the handle 11 by rotational connection and can drive the guide member 12 to move towards the handle 11 when it rotates relative to the handle 11. Specifically, the control member 31 is connected to the guide member 12, and at least one of the control member 31 and the guide member 12 is threadedly connected to the handle 11, so that when the control member 31 rotates, the guide member 12 is driven to move towards the handle 11 by the thread.

[0058] In one of the embodiments, please refer to Figure 9 In the embodiment, only the control member 31 is threadedly connected to the handle 11. When the control member 31 rotates, it can drive the guide member 12 to move towards the handle 11 by the thread between the control member 31 and the handle 11, so that the guide member 12 is separated from the electrode member 2.

[0059] In another embodiment, please refer to Figure 10 In the embodiment, only the guide member 12 is threadedly connected to the handle 11. The control member 31 penetrates the handle 11 and can rotate relative to the handle 11. When the control member 31 rotates, it can drive the guide member 12 to rotate. When the guide member 12 rotates, it can move towards the handle 11 by the thread between the guide member 12 and the handle 11, so that the guide member 12 is separated from the electrode member 2.

[0060] ​In another embodiment, the control member 31 and the guide member 12 can also be screwed with the handle 11 at the same time, the control member 31 and the guide member 12 have the same pitch and thread diameter, and the control member 31 can drive the guide member 12 to rotate synchronously relative to the handle 11 when the control member 31 rotates, so as to drive the guide member 12 to move towards the handle 11. Compared with the above two embodiments, the connection between the control member 31, the guide member 12 and the handle 11 is more stable.

[0061] In one of the embodiments, referring to Figure 11 , the electrode member 2 includes an electrode base 21 and an electrode contact 22, the electrode base 21 includes a first segment 211 and a second segment 212 arranged at an angle, and the electrode contact 22 is arranged on the first segment 211, and the second segment 212 is in interference fit with the guide member 12.

[0062] In the embodiment, the electrode member 2 is a flexible electrode made by using a silk screen printing technology, MEMS, laser and other micro-nano processing technologies, the electrode base 21 can be made of, but is not limited to, a high biocompatibility material such as polyimide, polyurethane or perlaplatin, and the electrode contact 11 can be made of, but is not limited to, a biocompatible metal material such as platinum, platinum-iridium, iridium oxide or titanium nitride. Based on the micro-nano processing technology, the width of the electrode member 2 can be 0.4mm-0.8mm, and the number of the electrode contact 22 can be 4 / 8 / 16 / 32 / 64 / 128, etc. A proper number of the electrode contact 22 can be selected according to the actual indications including, but not limited to, Parkinson's disease, depression, Alzheimer's disease, epilepsy and other neurological diseases, and any number of the electrode contact 22 can be programmed to record and stimulate through the post-CMOS circuit and the upper computer software.

[0063] The first segment 211 and the second segment 212 of the electrode base 21 in the embodiment are preferably arranged perpendicularly to each other, so that the second segment 212 is convenient to interfere fit with the guide member 12. The end of the first segment 211 away from the second segment 212 can be fixed on the handle 11 by a rope, so that the electrode member 2 will not be greatly deviated when it touches the brain tissue during being sent into the brain. When the guide member 12 is separated from the second segment 212, the rope can be cut to unlock the first segment 211, and at this time the handle 11 and the guide member 12 can be smoothly withdrawn from the brain. The interference fit connection between the second segment 212 and the guide member 12 makes the connection between the guide member 12 and the electrode member 2 more stable, and the guide member 12 can stably send the electrode member 2 into the brain lesion.

[0064] The interference fit between the second segment 212 and the guide member 12 has two cases, the first case is that the second segment 212 is provided with a hole, and the diameter of the guide member 12 is slightly larger than the hole diameter; the second case is that the guide member 12 is provided with a hole at the end, and the second segment 212 is provided with a cylindrical protrusion, and the diameter of the cylindrical protrusion is slightly larger than the hole diameter.

[0065] In a preferred embodiment, referring to Figure 11 , the second section 212 is provided with a positioning hole 213, and the positioning hole 213 is in interference fit with the guide 12. This embodiment only needs to open a hole in the second section 212, which is simple in process, and the guide 12 can be quickly and conveniently withdrawn from the positioning hole 213.

[0066] In an embodiment, referring to Figure 11 , the guide 12 comprises a guide body 121 and a clamping flange 122, one end of the guide body 121 is slidably connected to the handle 11, the other end of the guide body 121 is connected to the clamping flange 122, the diameter of the clamping flange 122 is smaller than the diameter of the guide body 121, and the clamping flange 122 is in interference fit with the positioning hole 213.

[0067] In this embodiment, the diameter of the clamping flange 122 is slightly larger than the diameter of the positioning hole 213, so that the clamping flange 122 can be in interference fit with the positioning hole 213. When the clamping flange 122 of this embodiment is in interference fit with the positioning hole 213, the guide body 121 can abut against the second section 212 to limit the clamping flange 122, avoiding that the clamping flange 122 easily damages normal tissues of the brain by excessively extending out of the positioning hole 213.

[0068] In an embodiment, referring to Figure 12 and Figure 13 , the guide assembly 1 further comprises a catheter 13, the catheter 13 is connected to the handle 11, the guide 12 is slidably arranged inside the catheter 13 and extends out of the end of the catheter 13 away from the handle 11 to detachably connect the electrode 2.

[0069] In this embodiment, the catheter 13 is hollow at both ends, one end of the catheter 13 is connected to the handle 11 and communicates with the inside of the handle 11. The guide 12 is located inside the catheter 13 and passes through the catheter 13, one end of the guide 12 extends out of the end of the catheter 13 away from the handle 11 and is in interference fit with the electrode 2, the other end of the guide 12 passes out of the other end of the catheter 13 into the inside of the handle 11 and is connected to the control member 31. Under the driving of the control member 31, the guide 12 can slide relative to the catheter 13 towards the handle 11 to be separated from the electrode 2. The catheter 13 of this embodiment is mainly used to support and guide the guide 12, so that the guide 12 is not easy to deform during the process of sending the electrode 2 into the brain, and the electrode 2 can be stably sent into the brain lesion.

[0070] In addition, the catheter 13 has a placement plane 131 for placing the electrode member 2, in particular for placing the first section 211 of the electrode member 2, to support the electrode member 2. No additional connection is formed between the placement plane 131 and the electrode member 2, for example, the placement plane 131 is not provided with adhesive to stick the electrode member 2, so that when the guide member 12 is separated from the electrode member 2, the catheter 13 can also be separated from the electrode member 2 to withdraw from the brain.

[0071] In one embodiment, referring to Figure 1 The outer wall of the handle 11 is provided with a connecting groove 114 for connecting with an external micro-propeller, so that the handle 11 is stably connected with the external micro-propeller.
