Description

Technical Field

[0001] The utility model relates to a medical device, in particular to a transcranial treatment device. Background Art

[0002] Transcranial magnetic stimulation (TMS) is a non-invasive neuromodulation technology with few side effects, which plays a huge role in cognitive neuroscience and clinical neurological function regulation. TMS can use the time-varying magnetic field generated by pulsed current to generate an induced electric field in brain tissue, thereby regulating neuronal excitability, stimulating specific brain functional cortex, and playing a role in treating a variety of brain diseases.

[0003] Similarly, transcranial physical therapy also includes transcranial electrical stimulation therapy, transcranial ultrasound stimulation therapy, and transcranial laser stimulation therapy. These have been clinically proven to be effective transcranial treatment methods, achieving corresponding unique therapeutic effects and solving some difficult cranial and brain problems. After decades of development and application, transcranial therapeutic devices have achieved good therapeutic effects in many fields of neuroregulation, as well as a large amount of literature support. And in the process of clinical use, they have also been widely recognized by doctors in related departments.

[0004] A treatment helmet is often used in transcranial treatment equipment. The treatment head is detachably fixed to the treatment helmet through a positioning and fixing mechanism. The positioning accuracy and stability of the positioning and fixing structure directly affect the effect of the transcranial treatment. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a uniquely structured transcranial therapeutic apparatus precision positioning fixture and its auxiliary positioner, which can more accurately, stably and quickly position and fix the treatment head at the corresponding position of the treatment helmet. At the same time, an auxiliary positioner is provided, which can assist in quickly and accurately fixing the treatment head at the accurate position of the precision positioning fixture.

[0006] In order to solve this technical problem, the technical solution adopted by the utility model is as follows:

[0007] A transcranial therapeutic instrument precise positioning fixture, which can match and be fixed to the edge of a through hole of a shell treatment head of a treatment helmet shell, comprises: an upper fixture and a lower fixture;

[0008] The lower fixture comprises a fixture bottom plate, which is matched and fixedly connected with the helmet shell through a slot structure and / or a pin hole structure, a bottom plate treatment head through hole matching the shell treatment head through hole is arranged in the middle of the fixture bottom plate, and a pair of lower fixture columns are arranged on opposite sides of the fixture bottom plate;

[0009] The upper fixture comprises a fixture top plate, and a pair of upper fixture columns matching the lower fixture columns are arranged on opposite sides of the fixture top plate; the upper fixture columns can be detachably fixedly connected to the lower fixture columns;

[0010] The treatment head can be placed in the space between the upper and lower clamps, matched and fitted on the through hole of the bottom plate treatment head, and then the treatment head is horizontally positioned by at least one pair of horizontal fixing screws, and the treatment head is vertically positioned by at least one vertical fixing screw; the horizontal fixing screw is threadedly connected to the lower clamp column and / or the upper clamp column, and the vertical fixing screw is threadedly connected to the clamp top plate.

[0011] Furthermore, the slot structure is as follows: a fixing groove is provided on the hole wall of the bottom plate treatment head through hole, which can be matched and fixedly plugged with the helmet shell through a shell fixing protrusion provided on the edge of the shell treatment head through hole.

[0012] Furthermore, the pin hole structure is as follows: the lower plane of the clamp base plate is provided with at least two fixing pins or fixing pin holes at the edge of the base plate treatment head through hole, which can be matched and fixedly plugged with the helmet shell through the fixing pin holes or fixing pins provided at the edge of the shell treatment head through hole.

[0013] Furthermore, at least one vertical fixing screw hole is matchedly arranged on the top plate of the clamp at a position corresponding to the through hole of the treatment head on the bottom plate, and the treatment head can be fixed in the vertical direction by screwing the vertical fixing screw through the distance of the vertical fixing screw hole.

[0014] Furthermore, a pair of the lower clamp columns are respectively provided with first horizontal fixing screw holes, and the treatment head can be positioned and fixed in the horizontal direction by screwing the horizontal fixing screws through the first horizontal fixing screw holes.

[0015] Furthermore, a pair of the upper clamp columns are respectively provided with second horizontal fixing screw holes matching the first horizontal fixing screw holes, and the horizontal fixing screws are threadedly connected through the second horizontal screw holes and the first horizontal screw holes in sequence.

[0016] Furthermore, a through slot on the treatment head handle is provided on the fixture top plate of the upper fixture, and when the treatment head handle is in an upwardly extending structural form, it can extend out from the through slot on the treatment head handle.

[0017] When the auxiliary positioner is fixedly connected to the fixture bottom plate, the indicating angle of the indicating portion coincides with the center point of the plane on the bottom plate of the bottom plate treatment head through hole.

[0018] At the same time, the utility model also provides an auxiliary locator for the above-mentioned transcranial therapeutic apparatus precise positioning fixture, the upper plane of the auxiliary locator has a fixed connection structure consistent with the edge structure of the shell treatment head through hole of the helmet shell, and the fixed connection structure can be matched and fixedly connected with the fixture bottom plate through the slot structure and / or pin hole structure;

[0019] An observation hole is provided at the center of the auxiliary positioner, and an indicator is provided in the observation hole. When the auxiliary positioner is fixedly connected to the fixture base plate, the indicator angle of the indicator coincides with the axial projection of the center of the through hole of the base plate treatment head.

[0020] Furthermore, a positioner fixing protrusion is provided on the upper plane of the auxiliary positioner, which can be matched and fixedly plugged with a fixing groove provided in the through hole of the base plate treatment head.

[0021] Furthermore, the upper plane of the auxiliary locator is provided with a locator fixing pin hole or a fixing pin column, which can match and be fixedly plugged with the fixing pin column or the fixing pin hole provided on the lower plane of the clamp bottom plate.

[0022] Furthermore, when the auxiliary positioner is fixedly connected to the fixture base plate, the indicating angle of the indicating portion coincides with the center point of the plane on the base plate of the base plate treatment head through hole.

[0023] The precise positioning fixture of the transcranial therapeutic device of the utility model places the treatment head therein through the upper and lower fixture structures that are detachably fixedly connected, and then sets a horizontal fixing structure and a vertical fixing structure. The treatment head can be accurately, stably and quickly fixed at the specified position of the positioning fixture, thereby greatly improving the use efficiency and treatment effect of the transcranial therapeutic device.

[0024] Fixing the treatment head in the accurate designated position in the positioning fixture is difficult in itself, and its position accuracy is directly related to further improving the treatment effect. The auxiliary locator uses its through-hole structure to completely replicate the center part of the through-hole of the shell treatment head of the helmet shell, and its fixing structure with the positioning fixture also replicates the structure of the helmet shell, so it completely simulates the helmet shell in the matching position, and the indicator set in the auxiliary locator corresponds to the center point of the through-hole of the bottom plate treatment head (that is, the center point of the through-hole of the shell treatment head of the helmet shell).

[0025] After installing the treatment head in the assembled transcranial therapeutic instrument precision positioning fixture, install the auxiliary positioner, then adjust the position of the treatment head so that the center point of its treatment surface coincides with the indication angle of the indicator needle in the observation hole of the auxiliary positioning plate, and finally tighten the horizontal and vertical fixing screws on the positioning fixture to accurately fix the treatment head in the correct position. At this time, remove the auxiliary positioner, install the positioning fixture and the treatment head on the helmet shell, and ensure that the center of the treatment surface of the treatment head is aligned with the center point of the shell treatment head through hole of the helmet shell. In this case, when the treatment is carried out, the treatment action center line of the treatment head can accurately pass through the designated intracranial treatment point, and the center of the treatment surface of the treatment head can also accurately fit and contact the patient's extracranial treatment point, thereby ensuring the accuracy of the treatment position and effectively improving the treatment effect.

[0049] The present invention is further described in detail below with reference to the accompanying drawings and embodiments:

[0050] Figure 1 A transcranial therapeutic device precision positioning fixture is shown, which can match and fix the edge of the shell treatment head through hole 101 (such as Figure 4 , Figure 5 As shown), comprising: an upper fixture 4 and a lower fixture 2.

[0051] The lower fixture 2 includes a fixture bottom plate 202, which is matched and fixedly connected to the helmet shell through a slot structure and / or a pin hole structure. A bottom plate treatment head through hole 2021 matching the shell treatment head through hole 101 is arranged in the middle of the fixture bottom plate 202, and a pair of lower fixture columns 201 are arranged on opposite sides of the fixture bottom plate 202.

[0052] Specifically, Figure 3 As shown, the slot structure is: a fixing groove 2022 is provided on the edge of the bottom plate treatment head through hole 2021, which can be matched and fixedly plugged with the helmet shell 1 through the shell fixing protrusion 102 provided on the edge of the shell treatment head through hole 101. The pin hole structure is: three fixing pins 2023 (or two or four, etc.) are provided on the lower plane of the clamp bottom plate 202 at the edge of the bottom plate treatment head through hole 2021, which can be matched and fixedly plugged with the helmet shell 1 through the shell fixing pin hole 103 provided on the edge of the shell treatment head through hole 101. Of course, the structure in which the clamp base plate 202 is provided with a fixing pin 2023 and the helmet shell 1 is provided with a shell fixing pin hole 103 can also be that the clamp base plate 202 is provided with a pin hole and the helmet shell 1 is provided with a pin; similarly, the structural setting of the fixing groove 2022 and the shell fixing protrusion 102 is also the same; as long as the clamp base plate 202 can be matched and fixedly connected with the helmet shell 1 through the slot structure and / or the pin hole structure.

[0053] The upper clamp 4 includes a clamp top plate 402, and a pair of upper clamp columns 401 matching the lower clamp columns 201 are arranged on opposite sides of the clamp top plate 402; the upper clamp columns can be detachably fixedly connected with the lower clamp columns. The specific structure is: the upper clamp column 401 is provided with a column slot 4011 at the inner wall, and the lower clamp column 201 can be matched and inserted into the column slot 4011 to circumferentially limit and position the upper clamp, and a horizontal detachable fixing structure is provided to fix the lower clamp column 201 and the upper clamp column 401, which can be a pin / hole fixing structure or a fixing screw structure, etc. As a more optimized implementation, we can use the horizontal fixing screw 3 used for horizontal positioning of the treatment head 6 as a detachable fixing structure of the lower clamp column 201 and the upper clamp column 401.

[0054] Two first horizontal fixing screw holes 2011 arranged at the same level are respectively opened on a pair of the lower clamp columns 201. When installing, the treatment head 6 is placed between the upper and lower clamps 4 and 2, and the position is adjusted. The horizontal fixing screw 3 is screwed inward from the outside to pass through the first horizontal fixing screw hole 2011 and presses against the side wall of the treatment head 6. The treatment head 6 is positioned and fixed in the horizontal direction by adjusting the screwing distance of the horizontal fixing screw 3. Figure 2 shown.

[0055] The structural form in which each lower clamp column 201 is provided with two first horizontal fixing screw holes 2011 can also be a pair of lower clamp columns 201 provided with three first horizontal fixing screw holes 2011, or other number of first horizontal fixing screw holes 2011, as long as the treatment head 6 can be positioned and fixed in the horizontal direction through a number of first horizontal fixing screw holes 2011.

[0056] A pair of upper clamp columns 401 are respectively provided with second horizontal fixing screw holes 4012 matching the first horizontal fixing screw holes 2011, and the horizontal fixing screws 3 are threadedly connected through the second horizontal screw holes 4012 and the first horizontal screw holes 2011. In this way, the lower clamp column 201 and the upper clamp column 401 are detachably fixedly connected by the horizontal fixing screws 3. Of course, the horizontal fixing screws 3 can also be set to be threadedly connected only to the lower clamp column 201 or the upper clamp column 401, while the lower clamp column 201 or the upper clamp column 401 is fixedly connected by other connecting parts.

[0057] The clamp top plate 402 is provided with three vertical fixing screw holes 4021 (it can also be one or other number) at positions corresponding to the through holes 2021 of the bottom plate treatment head. During installation, after the treatment head 6 is put in place, the vertical fixing screws 5 are screwed through the vertical fixing screw holes 4021 to press against the treatment head 6, and the treatment head is fixed in the vertical direction by adjusting the screwing distance.

[0058] The treatment head 6 can be placed in the space between the upper and lower clamps 4, 2, matched and fitted on the bottom plate treatment head through hole 2021, and then the treatment head 6 is horizontally positioned by at least one pair of horizontal fixing screws 3, and the treatment head 6 is vertically positioned by at least one vertical fixing screw 5; the horizontal fixing screw 3 is threadedly connected to the lower clamp column 201 and / or the upper clamp column 401, and the vertical fixing screw is threadedly connected to the clamp top plate.

[0059] In order to make the positioning clamp of the utility model compatible with more different types of treatment heads 6, a treatment head handle upper through slot 4022 may also be opened on the clamp top plate 402 of the upper clamp 4, and the treatment head handle upper through slot 4022 is open to one side so that the treatment head handle 602 can be inserted into the slot during installation. When the handle 602 of the corresponding style of treatment head 6 is an upward extending structure, the treatment head handle 602 can be extended from the treatment head handle upper through slot 4022.

[0060] When we install the treatment head on the positioning fixture on the helmet shell, the accuracy of its positioning will directly affect the treatment effect. Then, due to the limitations of the helmet and the fixture structure, it is difficult to quickly and accurately find a very accurate position. Therefore, the utility model also provides an auxiliary positioner 7 for the above-mentioned transcranial therapeutic device precise positioning fixture, such as Figure 6 As shown, the upper plane of the auxiliary locator 7 has a fixed connection structure that is consistent with the edge structure of the shell treatment head through hole 101 of the helmet shell 1.

[0061] The upper plane of the auxiliary locator 7 is provided with a locator fixing protrusion 701, which can be matched and fixedly inserted with the fixing groove 2022 set at the edge of the bottom plate treatment head through hole 2021. The upper plane of the auxiliary locator 7 is provided with a locator fixing pin hole 702, which can be matched and fixedly inserted with the fixing pin column 2023 set on the lower plane of the clamp bottom plate 202, so that the connection between the auxiliary locator 7 and the positioning clamp is consistent with the fixed connection between the helmet shell 1 and the positioning clamp.

[0062] Similarly, here, the connection structure between the fixing groove 2022 and the locator fixing protrusion 701, and the connection structure between the fixing pin 2023 and the locator fixing pin hole 702 can also be interchangeable in terms of the slot positions and the column hole positions, as long as the auxiliary locator can be matched and fixedly connected with the clamp base plate 202 through the slot structure and / or pin hole structure.

[0063] The auxiliary locator 7 is provided with an observation hole 703 in the center, and an indicator pin 704 is provided in the observation hole 703. When the auxiliary locator 7 is fixedly connected to the fixture base plate 202, the indicator tip 7041 of the indicator pin 704 coincides with the axial projection of the center of the base plate treatment head through hole 2021. In this way, when the auxiliary locator 7 is fixedly connected to the fixture base plate 202, the indicator pin 704 in the observation hole 703 can intuitively assist the treatment head 6 in positioning and installing. A center mark 601 is provided in the center of the treatment surface of the treatment head 6, such as Figure 3 After the auxiliary locator 7 is installed, the point indicated by the pointed end 7041 of the indicating needle 704 is the standard position where the center of the treatment surface of the treatment head 6 (center mark 601) should be placed, such as Figure 7 As shown; at this time, it is only necessary to adjust the position of the treatment head 6 so that the indicating pointed end 7041 coincides with the axial projection of the treatment head center mark 601, indicating that the treatment head 6 has entered the standard position; then the treatment head 6 can be fixed in the standard position by tightening the horizontal fixing screw 3 and the vertical fixing screw 5; then the auxiliary positioner 7 is removed, and the transcranial therapeutic instrument precision positioning fixture with the treatment head fixed is fixed to the helmet shell 1 with the same slot structure and / or pin hole structure, and the treatment surface center of the treatment head 6 can be axially coincident with the center point of the shell treatment head through hole 101, as shown in FIG. Fig. 9 As shown, the treatment action centerline 603 of the treatment head 6 can accurately pass through the designated intracranial treatment point 8, and the center of the treatment surface of the treatment head can also accurately fit and contact the patient's extracranial treatment point 9 (a point on the surface of the patient's head), thereby ensuring the accuracy of the treatment position and effectively improving the treatment effect.

[0064] Of course, the above-mentioned indicator needle 704 is arranged in the observation hole 703, and the indicator needle 704 has a structure of an indicating pointed end 7041. It can also be other structural forms that can play a center indicating role. For example, a transparent cross or cross component can be arranged in the observation hole 703, and its intersection point is used as the indicating angle. During operation, it is axially coincident with the center of the through hole 2021 of the base plate treatment head or the center of the treatment surface of the treatment head 6. As long as an indicating part is arranged in the observation hole 703, when the auxiliary locator 7 is fixedly connected to the clamp base plate 202, the indicating angle of the indicating part (in the above embodiment, the indicating angle is the indicating pointed end 7041 of the indicator needle 704, and in another embodiment, it is the cross intersection point) coincides with the axial projection of the center of the through hole 2021 of the base plate treatment head.

[0065] Preferably, Fig. 9 As shown, when the auxiliary positioner 7 is fixedly connected to the fixture base plate 202, the indicating pointed end 7041 of the indicating needle 704 coincides with the center point 20211 of the plane on the base plate of the base plate treatment head through hole 2021.

[0066] In this way, when the auxiliary locator 7 is installed on the precise positioning fixture of the treatment head, and the treatment head is installed and adjusted into place, the indicating pointed end 7041 of the indicating needle 704 can be aligned with the center point of the treatment surface of the treatment head 6 (center mark 601), that is, when the treatment head 6 is installed to the standard position, not only the indicating pointed end 7041 of the indicating needle 704 is aligned with the center point of the treatment surface of the treatment head 6 in axial projection, but also the indicating pointed end 7041 is in close contact with the center point of the treatment surface of the treatment head 6. In this way, while adjusting the planar position of the treatment head 6, it is possible to detect whether the positioning fixture is deformed or over-assembled. If, after the fixture has been used for a period of time, when the auxiliary locator 7 and the treatment head 6 are installed in place, the indicating pointed end 7041 cannot be aligned with the center point of the treatment surface of the treatment head 6 or the treatment head 6 is pushed up, it means that the precise positioning fixture has been somewhat deformed or too much force has been applied in some positions during the installation process, and the fixture needs to be readjusted.

[0067] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
