Description

Technical Field

[0001] This invention relates to the field of bioelectric stimulation acquisition technology, specifically to a bioelectric stimulation and acquisition device. Background Technology

[0002] In modern medical diagnosis and treatment, especially in clinical neuroscience and cardiac electrophysiology research, the acquisition of bioelectrical signals and external stimulation are the two most critical basic operations. Stimulation electrodes are mainly for the output and targeting of external electrical signals, while acquisition electrodes focus on high-sensitivity, low-noise signal input. Through electrodes, external stimulation pulses are precisely applied to tissues or cells, while electrophysiological response data of the target area are collected to determine the functional status of tissues, assess the pathological mechanisms of diseases, and guide treatment plans.

[0003] However, in common clinical procedures, doctors often need to alternate between stimulation and acquisition in the same target area. The existing stimulation and acquisition devices are always relatively separate in function and structure, requiring frequent changes of instruments or movement of electrode positions, which can easily lead to deviations in target localization and affect the effectiveness of experiments or treatments.

[0004] Therefore, there is an urgent need for a bioelectric stimulation and acquisition device that can perform multi-directional data acquisition without changing instruments or moving electrode positions, in order to solve the problems mentioned in the background art. Summary of the Invention

[0005] To overcome the aforementioned deficiencies of the prior art, the present invention provides a bioelectric stimulation and acquisition device. By driving the acquisition head to rotate along the axial direction, the acquisition area is increased, providing doctors with more acquisition points and facilitating the search for the optimal acquisition point. At the same time, the acquisition head moves in a circular motion around the stimulation electrode, eliminating the need to change or move the stimulation electrode position, preventing target positioning deviation of the stimulation electrode, realizing multi-directional acquisition, and improving acquisition quality, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A bioelectric stimulation and acquisition device includes: an encapsulation tube and an acquisition head and stimulation electrodes integrated therein. The two ends of the encapsulation tube are respectively provided with a hemispherical cap and a tube seat, wherein the hemispherical cap is encapsulated at the first end of the encapsulation tube and the tube seat is rotatably installed at the tail end of the encapsulation tube.

[0008] One end of the stimulation electrode is installed at the center of the inner cavity end plate of the tube seat, and the other end is attached to the inner cavity wall of the hemispherical cap. A collection tube is set on the end face of the inner cavity end plate of the tube seat on one side of the stimulation electrode. The collection head is set in the inner cavity of the collection tube and can slide and rotate along the axial direction of the collection tube.

[0009] The hemispherical cap consists of a contact positioning part, a central rotating part, and a connecting positioning part. The inner wall of the central rotating part is provided with a bend. One end of the collection tube near the hemispherical cap is inserted into the inner cavity of the bend. The collection head slides into the bend along the axial direction of the collection tube and extends out of the central rotating part. The collection tube can drive the central rotating part to rotate between the contact positioning part and the connecting positioning part through the rotation of the tube seat.

[0010] As a further aspect of the present invention: a deformable rod is provided at the tail of the collection head. The deformable rod is made of a flexible aluminum-magnesium alloy hose that is malleable, has strong support and flexibility. The deformable rod slides into the bend along the axial direction of the collection tube and deforms along the inner bending path of the tube.

[0011] As a further embodiment of the present invention: the transverse inner diameter of the end of the bend away from the collection tube gradually increases, and the outer wall of the middle rotating part is provided with a rounded rectangular opening that communicates with the inner cavity of the bend. After deformation, the deformed rod rotates along the axial direction of the collection tube and swings left and right in the rounded rectangular opening.

[0012] As a further embodiment of the present invention: one end of the collection tube extends to the lower part of the inner cavity end plate of the tube seat, and the end of the collection tube located below the inner cavity end plate of the tube seat is provided with a driving mechanism for driving the collection head to rotate. The driving mechanism includes an end cap, which is rotatably installed at the tail end of the collection tube. The end face of the end cap is provided with a positioning tube, which extends to the inner cavity of the collection tube. The tail end of the deformation rod is provided with a connecting tube, which is fitted onto the outer wall of the positioning tube. The outer wall of the positioning tube is provided with a limiting protrusion for driving the connecting tube to rotate. The inner cavity wall of the connecting tube is provided with a limiting groove, and the limiting protrusion is slidably installed in the limiting groove.

[0013] As a further embodiment of the present invention: a threaded rod is threadedly installed at the center of the positioning tube on the end face of the end cap. One end of the threaded rod extends into the inner cavity of the connecting tube and is rotatably installed on its inner wall. The connecting tube can axially push or pull the deformable rod in the inner cavity of the collection tube by the rotation of the threaded rod on the outer wall of the positioning tube.

[0014] As a further embodiment of the present invention: a convex tube is provided at one end of the collection tube near the hemispherical cap, the convex tube is inserted into the inner cavity of the curved tube, and the collection tube drives the central rotating part to rotate between the contact positioning part and the connection positioning part through the convex tube and the curved tube.

[0015] As a further embodiment of the present invention: the shape of the acquisition head is spherical, and the apex of the acquisition head extending into the central rotating part is flush with the apex of the hemispherical cap.

[0016] As a further embodiment of the present invention: the inner cavity of the encapsulation tube is provided with a cylindrical filler, the cylindrical filler surrounds the outside of the stimulation electrode and the acquisition tube and fills the gap between them, and the cylindrical filler does not contact the inner cavity wall of the encapsulation tube. The cylindrical filler is an insulating filler, which includes insulating glue and insulating ceramic.

[0017] Compared with the prior art, the advantages of the present invention are as follows:

[0018] By setting up a collection tube, the collection head is driven to slide axially into the curved tube and move out of the hemispherical cap. Then, the deformable rod outside the hemispherical cap is bent so that the apex of the collection head is aligned with the apex of the hemispherical cap. At the same time, the deformable rod in the collection tube is driven to rotate along the axial direction of the collection tube and swing left and right within the rounded rectangular opening, so that the collection head moves in an arc on one side of the stimulation electrode, increasing the collection area and providing doctors with more collection points, making it easier to find the best collection point. Moreover, the collection tube is driven by the tube seat to rotate the central rotating part between the contact positioning part and the connection positioning part around the stimulation electrode as the axis, so that the collection head moves around the stimulation electrode in a circle. There is no need to change or move the stimulation electrode position, preventing the stimulation electrode from being misaligned, realizing multi-directional collection and improving the collection quality.

Detailed Implementation

[0027] Combination Figure 1 - Figure 7 As shown in this embodiment, a bioelectric stimulation and acquisition device includes: a package tube 1 and an acquisition head 2 and a stimulation electrode 3 integrated inside it; the acquisition head 2 and the stimulation electrode 3 are respectively connected to the acquisition host and the stimulation host, and the external stimulation pulse is precisely applied to the tissue or cell through the stimulation electrode 3. At the same time, the acquisition head 2 acquires the electrophysiological response data of the target area, and the tissue functional status is judged, the pathological mechanism of the disease is evaluated, and the treatment plan is guided based on the electrophysiological response data.

[0028] In this embodiment, a hemispherical cap 11 and a tube seat 12 are respectively provided at both ends of the encapsulation tube 1. The hemispherical cap 11 is encapsulated at the first end of the encapsulation tube 1, and the tube seat 12 is rotatably installed at the tail end of the encapsulation tube 1. The acquisition head 2 and the stimulation electrode 3 are integrated and installed inside the encapsulation tube 1 by using the hemispherical cap 11 and the tube seat 12, thereby realizing the integrated assembly of the acquisition head 2 and the stimulation electrode 3.

[0029] In this embodiment, one end of the stimulation electrode 3 is installed at the center of the inner cavity end plate of the tube seat 12, and the other end is attached to the inner cavity wall of the hemispherical cover 11. The stimulation electrode 3 is attached to the inner cavity wall of the hemispherical cover 11, and the external stimulation pulse is transmitted through the hemispherical cover 11 and acts on the tissue or cell, thus satisfying the use of the stimulation electrode 3.

[0030] In this embodiment, the hemispherical cap 11 is composed of a contact positioning part 111, a central rotating part 112, and a connecting positioning part 113. Furthermore, the inner wall of the central rotating part 112 is provided with a bent tube 114. One end of the collection tube 4 near the hemispherical cap 11 is inserted into the inner cavity of the bent tube 114. The collection head 2 slides into the bent tube 114 along the axial direction of the collection tube 4 and extends out of the central rotating part 112. The collection tube 4 can drive the central rotating part 112 to rotate between the contact positioning part 111 and the connecting positioning part 113 through the rotation of the tube seat 12. 11 contacts the tissue, and the connecting positioning part 113 connects to the encapsulation tube 1. The drive tube seat 12 rotates, causing the collection tube 4 to rotate around the stimulation electrode 3 as the axis, and the central rotating part 112 rotates between the contact positioning part 111 and the connecting positioning part 113. This allows the collection head 2 to move around the stimulation electrode 3 in a circular motion, without the need to change or move the position of the stimulation electrode 3. This prevents the stimulation electrode 3 from being misaligned, achieves multi-directional collection, and improves the collection quality. Moreover, the contact positioning part 111 does not need to rotate when in contact with the tissue, which can prevent damage caused by the rotation and friction of the hemispherical cap 11 on the tissue surface.

[0031] In this embodiment, a deformable rod 21 is provided at the tail of the collection head 2. The deformable rod 21 is made of a shapeable, supportive, and flexible aluminum-magnesium alloy flexible tube. After the deformable rod 21 slides into the bend 114 along the axial direction of the collection tube 4, it deforms along the inner bending path of the bend 114. The deformable rod 21 is driven to slide axially in the collection tube 4 and is driven into the inner cavity of the bend 114. The deformable rod 21, which is made of a shapeable, supportive, and flexible aluminum-magnesium alloy flexible tube, deforms and bends along the inner bending path of the bend 114, pushing the collection head 2 to move out of the hemispherical cap 11. This avoids the collection head 2 being unable to extend out of the hemispherical cap 11 and contact the tissue due to interference between the deformable rod 21 and the bend 114, thus enabling the collection head 2 to extend.

[0032] In this embodiment, the lateral inner diameter of the end of the bent tube 114 away from the collection tube 4 gradually increases. The outer wall of the middle rotating part 112 is provided with a rounded rectangular opening that communicates with the inner cavity of the bent tube 114. The deformed rod 21 after deformation rotates along the axial direction of the collection tube 4 and swings left and right in the rounded rectangular opening. The deformed rod 21 in the collection tube 4 is driven to rotate along the axial direction of the collection tube 4, so that the bent deformed rod 21 in the inner cavity of the bent tube 114 swings left and right in the rounded rectangular opening, increasing the range of motion of the deformed rod 21 and preventing the deformed rod 21 from being unable to swing due to the diameter. At the same time, the swinging deformed rod 21 drives the collection head 2 to move in an arc on one side of the stimulation electrode 3, increasing the collection area and providing doctors with more collection points to facilitate finding the best collection point.

[0033] In this embodiment, one end of the collection tube 4 extends below the inner cavity end plate of the tube seat 12. A driving mechanism for rotating the collection head 2 is provided at the end of the collection tube 4 located below the inner cavity end plate of the tube seat 12. The driving mechanism includes an end cap 41, which is rotatably mounted on the tail end of the collection tube 4. A positioning tube 42 is provided on the end face of the end cap 41, extending into the inner cavity of the collection tube 4. A connecting tube 22 is provided at the tail end of the deformable rod 21, and the connecting tube 22 is fitted onto the outer wall of the positioning tube 42. The end cap 41 is driven to rotate at the tail end of the collection tube 4, causing the positioning tube 42 on the end face of the end cap 41 to rotate. The rotating positioning tube 42 drives the connecting tube 22 fitted onto its outer wall to rotate, thereby driving the deformable rod 21 on the connecting tube 22 to rotate axially within the collection tube 4, thus driving the collection head 2 to rotate axially along the collection tube 4.

[0034] In this embodiment, the outer wall of the positioning tube 42 is provided with a limiting protrusion for driving the connecting tube 22 to rotate, and the inner wall of the connecting tube 22 is provided with a limiting groove, and the limiting protrusion is slidably installed in the limiting groove; the limiting protrusion is used to limit the position of the connecting tube 22, so that the connecting tube 22 rotates with the rotation of the positioning tube 42, preventing the positioning tube 42 from rotating on its own inside the connecting tube 22. At the same time, the connecting tube 22 slides outside the positioning tube 42 and the limiting protrusion through the limiting groove, so as not to interfere with the axial sliding of the connecting tube 22.

[0035] In this embodiment, a threaded rod 43 is threadedly installed at the center of the positioning tube 42 on the end face of the end cap 41. One end of the threaded rod 43 extends into the inner cavity of the connecting tube 22 and is rotatably installed on its inner wall. The connecting tube 22 can axially push or pull the deformable rod 21 in the inner cavity of the collection tube 4 by the rotation of the threaded rod 43 on the outer wall of the positioning tube 42. The threaded rod 43 is driven to rotate in the forward direction, so that the threaded rod 43 extends into the inner cavity of the positioning tube 42 through the threaded hole on the end face of the end cap 41 and pushes the connecting tube 22 to slide axially. The sliding connecting tube 22 pushes the deformable rod 21 to slide axially into the bend tube 114, thereby realizing the axial sliding of the collection head 2 and the deformable rod 21 in the collection tube 4.

[0036] The threaded rod 43 is driven to rotate in the opposite direction, so that the threaded rod 43 moves out of the collection tube 4 through the threaded hole on the end face of the end cap 41, pulling the connecting tube 22 to slide down and fit on the outside of the positioning tube 42. At the same time, the connecting tube 22 pulls the deformable rod 21 and the collection head 2 through the bend 114 into the collection tube 4, realizing the storage of the collection head 2 and the vertical stretching of the deformable rod 21.

[0037] In this embodiment, a protruding tube 44 is provided at one end of the collection tube 4 near the hemispherical cover 11. The protruding tube 44 is inserted into the inner cavity of the bent tube 114, and the collection tube 4 drives the central rotating part 112 to rotate between the contact positioning part 111 and the connection positioning part 113 through the protruding tube 44 and the bent tube 114. The protruding tube 44 is used to insert the collection tube 4 into the bent tube 114, connecting the inner cavity of the bent tube 114 and the collection tube 4. The inner cavity of the bent tube 114 and the collection tube 4 are spliced ​​together to form a moving channel, allowing the collection head 2 to move along the moving channel to the outside of the hemispherical cover 11, realizing the extension of the collection head 2. At the same time, by driving the collection tube 4 to rotate around the stimulation electrode 3 as the axis, the rotating collection tube 4 drives the bent tube 114 and the central rotating part 112 to rotate between the contact positioning part 111 and the connection positioning part 113, satisfying the multi-directional collection needs of the collection head 2.

[0038] In this embodiment, the acquisition head 2 is spherical in shape, and the apex of the acquisition head 2 extending into the central rotating part 112 is flush with the apex of the hemispherical cover 11. When used for the first time, the acquisition head 2 and the stimulation electrode 3 make synchronous contact with the tissue. If the parameters acquired by the acquisition head 2 for the first time meet the requirements, there is no need to adjust the acquisition head 2.

[0039] In this embodiment, the inner cavity of the encapsulation tube 1 is provided with a cylindrical filler. The cylindrical filler surrounds the outside of the stimulation electrode 3 and the acquisition tube 4 and fills the gap between them. The cylindrical filler does not contact the inner cavity wall of the encapsulation tube 1. The cylindrical filler is an insulating filler, which includes insulating glue and insulating ceramic. The outside of the stimulation electrode 3 and the acquisition tube 4 is filled with insulating glue, insulating ceramic and other insulating fillers using a mold cavity. After demolding, the integrated encapsulated stimulation electrode 3 and acquisition tube 4 are obtained, realizing the integration of stimulation electrode 3 and acquisition head 2. The processing difficulty is low. Moreover, the use of insulating glue, insulating ceramic and other fillers can prevent mutual interference between stimulation electrode 3 and acquisition head 2, ensuring the use effect of stimulation electrode 3 and acquisition head 2.

[0040] The bioelectric stimulation and acquisition device proposed in this invention integrates a stimulation electrode 3 and an acquisition head 2. The acquisition head 2 and the deformable rod 21 are driven to slide axially within the acquisition tube 4, propelling them into the inner cavity of the curved tube 114. This causes the deformable rod 21 to deform and bend along the bending path within the curved tube 114, pushing the acquisition head 2 out of the hemispherical cap 11. The deformable rod 21 outside the hemispherical cap 11 is then bent, aligning the apex of the acquisition head 2 with the apex of the hemispherical cap 11 for synchronous contact with the tissue. Simultaneously, the deformable rod 21 within the acquisition tube 4 is driven to move along its... The axial rotation and left-right swing within the rounded rectangular opening allow the acquisition head 2 to move in an arc shape on one side of the stimulation electrode 3, increasing the acquisition area and providing doctors with more acquisition points to facilitate finding the optimal acquisition point. Then, the acquisition tube 4 is driven by the tube seat 12 to rotate the central rotating part 112 between the contact positioning part 111 and the connecting positioning part 113 around the stimulation electrode 3, allowing the acquisition head 2 to move around the stimulation electrode 3 in a circle. This eliminates the need to change or move the position of the stimulation electrode 3, prevents targeting deviation of the stimulation electrode 3, achieves multi-directional acquisition, and improves acquisition quality.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
