Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to a trigeminal ganglion compression device. Background Art

[0002] The mechanism of action of trigeminal nerve balloon compression (PBC) is that the balloon is inflated and compressed at the trigeminal ganglion, mechanically damaging the nerve root and trigeminal ganglion, thereby weakening the pain nerve signals in the trigeminal nerve area and achieving a therapeutic effect. Generally, the main factors affecting the treatment effect during trigeminal nerve semilunar ganglion balloon compression surgery include the balloon filling shape and compression time. Among them, the shape of the balloon is not easy to control. Doctors mainly use images to determine whether the balloon is filled to the ideal shape (such as pear shape). The judgment of the balloon filling shape is greatly influenced by the doctor's subjective factors, and it is impossible to quantitatively evaluate the treatment effect. This leads to large differences in treatment effects between different doctors, and even between different patients treated by the same doctor. The treatment effect varies greatly, affecting the cure rate of the disease and is not conducive to the promotion and application of trigeminal nerve semilunar ganglion balloon compression technology.

[0034] Example 1

[0035] Please also see Figures 1 to 5 A trigeminal ganglion compression device according to one embodiment includes: a balloon 10, a support tube 30, a first electrode 14, a second electrode 15, a first wire 16, a second wire 17 and a connector 18. The connector 18 is provided with an injection cavity 181. One end of the support tube 30 is inserted into the balloon 10, and the other end of the support tube 30 is connected to the connector 18, and the support tube 30 is connected to the injection cavity 181. The first electrode 14 and the second electrode 15 are both used to collect nerve signals. The first electrode 14 is arranged at the proximal end of the balloon 10. One end of the first wire 16 is connected to the first electrode 14, and the other end extends to the outside of the balloon 10. The second electrode 15 is configured to fit on the patient's face, and the second wire 17 is connected to the second electrode 15.

[0036] In one embodiment, the first electrode 14 and the second electrode 15 can be, but are not limited to, sheet-shaped or tubular. The first electrode 14 is clamped and fixed to the support tube 30 on the proximal side of the balloon 10, and the second electrode 15 is configured to fit the patient's face during use. Specifically, the distal and proximal ends of the balloon 10 are fixed to the inner support tube 30 by bonding, high-strength fiber winding, welding, or heat sealing. The first wire 16 extends to the outside of the balloon 10 and is connected to an external electrophysiological nerve signal monitoring device. The second wire 17 can be directly connected to the external electrophysiological nerve signal monitoring device. Further, in one embodiment, the first wire 16 and the second wire 17 are respectively connected to the electrophysiological nerve signal monitoring device to form a closed loop. Specifically, in this embodiment, the support tube 30 is a single-lumen tube. The inner lumen of the support tube 30 serves as both a fluid channel and a guidewire channel. The portion of the support tube 30 located inside the balloon 10 is provided with a plurality of circular, elliptical, or other shaped through-holes 36, through which the contrast agent is injected into the balloon 10. Furthermore, the support tube 30 is made of medical polymer materials, specifically but not limited to PVC, PU, ​​PA, PE, PP and other medical polymer materials.

[0037] When the above-mentioned trigeminal ganglion compression device is used, the first electrode 14 and the second electrode 15 are connected to an external electrophysiological nerve signal monitoring device through the first wire 16 and the second wire 17 respectively. The electrophysiological nerve signal monitoring device can monitor the size of the patient's trigeminal nerve pain nerve signal before and during the operation, so that the difference in nerve signals can be used to determine whether the treatment has achieved the expected pain-relieving effect. The treatment effect can be quantitatively evaluated, and the defect of uneven treatment effects caused by the lack of a quantitative parameter to evaluate treatment standards in the clinic can be effectively overcome. Clinical experiments have verified that the above-mentioned trigeminal ganglion compression device can achieve the clinical effects of precise treatment, rapid treatment, improved prognosis, and reduced complications by monitoring the difference in nerve signals before and after treatment. It can improve the cure rate of the disease and is conducive to the widespread promotion and application of trigeminal ganglion balloon compression technology.

[0038] In one embodiment, the trigeminal ganglion compression device further includes a sealing head 19 having a curved surface 191. The sealing head 19 passes through the balloon 10 and is fixedly connected to the support tube 30. Specifically, the curved surface 191 on the sealing head 19 can reduce resistance during the advancement of the trigeminal ganglion compression device, ensure smooth advancement, and help improve surgical efficiency. The sealing head 19 can be made of metal such as stainless steel or medical polymer materials such as PVC. The sealing head 19 is partially inserted into the support tube 30 and is fixedly connected to the support tube 30 by bonding, welding or heat sealing.

[0039] In one embodiment, the trigeminal ganglion compression device also includes: a first metal buckle 20 and a second metal buckle 21, the first metal buckle 20 is sleeved on the outer side of the distal end of the balloon 10, and the first metal buckle 20 fastens and fixes the distal end of the balloon 10 to the support tube 30, and the second metal buckle 21 is sleeved on the outer side of the proximal end of the balloon 10, and the second metal buckle 21 fastens and fixes the proximal end of the balloon 10 to the support tube 30.

[0040] Specifically, the first metal buckle 20 and the second metal buckle 21 are both in the form of metal tubes or wires and can be made of stainless steel, tungsten, titanium, platinum, gold, silver, or alloys. The first and second metal buckles 20, 21 are used to provide X-ray visualization during surgery, clearly indicating the position of the balloon 10 within human tissue. In this embodiment, the first metal buckle 20 further secures the distal end of the balloon 10 to the support tube 30, while the second metal buckle 21 secures the proximal end of the balloon 10 to the support tube 30, ensuring a stable and reliable connection between the balloon 10 and the support tube 30.

[0041] In one embodiment, the trigeminal ganglion compression device further includes a syringe 22, which is pluggably connected to the connector 18. Specifically, the syringe 22 is used to inject a contrast agent into the injection cavity 181 of the connector 18. After entering the injection cavity 181, the contrast agent enters the balloon 10 through the support tube 30, causing the balloon 10 to inflate and compress the trigeminal nerve, thereby achieving the therapeutic purpose.

[0042] In one embodiment, the syringe 22 is further provided with a threaded portion 221, and the connector 18 is provided with a thread, and the threaded portion 221 is threadedly connected to the connector 18. In this embodiment, the syringe 22 is threadedly connected to the connector 18, which can improve the sealing performance of the trigeminal ganglion compression device. Specifically, in this embodiment, the threaded portion 221 is provided with an internal thread, and the connector 18 is provided with an external thread. Of course, in other embodiments, the threaded portion 221 can also be provided with an external thread and the connector 18 can be provided with an internal thread, which can also achieve the same technical effect. This embodiment does not specifically limit this.

[0043] In one embodiment, the balloon 10 is a spherical balloon (e.g. Figure 2 As shown) or capsule-type balloon, the balloon 10 is made of elastic material, specifically compliant or semi-compliant material. Figure 3As shown, in another embodiment, balloon 10 is a pear-shaped balloon made of a pear-shaped water jacket. Accordingly, the balloon 10 can be made of natural latex, polyurethane, thermoplastic elastomer, silicone, or rubber. Specifically, after expansion during surgery, the shape of balloon 10 can change to conform to human tissue, taking on a pear-shaped or other shape. In practical applications, balloon 10 can be of any shape as needed, and the above embodiment is not intended to be a specific limitation.

[0044] In one embodiment, a mounting portion 37 is provided on the support tube 30, and the second electrode 15 is detachably connected to the mounting portion 37. Specifically, the second electrode 15 is detachably connected to the mounting portion 37. When the trigeminal ganglion compression device is working, the second electrode 15 is removed from the mounting portion 37 and attached to the patient's face. After the operation, the second electrode 15 is mounted on the mounting portion 37. This can prevent the second electrode 15 from being lost when placed alone, making it convenient to use. Furthermore, in one embodiment, the second electrode 15 is snap-connected to the mounting portion 37. Specifically, the mounting portion 37 can be a groove provided on the outer surface of the support tube 30, or a protrusion with a snap-on groove provided on the outer surface of the support tube 30. The specific structure of the mounting portion 37 can be arbitrarily set according to actual needs, and this embodiment does not make any specific restrictions.

[0045] Example 2

[0046] In the above embodiment 1, the support tube 30 of the trigeminal ganglion compression device is a single-lumen tube. In other embodiments, the support tube 30 can also be a multi-lumen tube. In this embodiment, the support tube 30 is a double-lumen tube. Figures 6 and 7 The support tube 30 has two cavities, which respectively form a fluid channel 31 and a guidewire channel 33. A guidewire through hole 183 is provided on the connector 18. The fluid channel 31 is connected to the balloon 10 and the injection cavity 181, respectively, and the guidewire channel 33 is connected to the balloon 10 and the guidewire through hole 183. Specifically, the support tube 30 includes an inner support tube 34 and an outer support tube 35. The inner support tube 34 is sleeved on the inner side of the outer support tube 35. The inner support tube 34 and the outer support tube 35 are sleeved to form a double-lumen structure, wherein the inner cavity of the inner support tube 34 serves as a guidewire channel, and the gap between the inner support tube 34 and the outer support tube 35 forms another cavity as a fluid channel. The contrast agent enters the balloon 10 through the gap between the inner support tube 34 and the outer support tube 35, thereby eliminating the need to open through holes on the inner support tube 21 and the outer support tube 35. In this embodiment, the support tube 30 forms a double-lumen structure by sleeve-jointing an inner support tube 34 and an outer support tube 35. In other embodiments, the support tube 30 may also directly adopt a double-lumen tube, with one cavity of the double-lumen tube serving as a fluid channel 31 and the other cavity serving as a guidewire channel 33. In actual applications, the specific structure of the support tube 30 may be selected according to actual needs, and this embodiment does not make any specific limitations.

[0047] Furthermore, in this embodiment, one end of the inner support tube 34 is connected to the distal end of the balloon 10, and the other end of the inner support tube 34 extends outside the balloon 10 and is inserted into the connector 18 to communicate with the injection cavity 181. The outer support tube 35 is sleeved outside the inner support tube 34, one end of the outer support tube 35 is connected to the proximal end of the balloon 10, and the other end of the outer support tube 35 is connected to the connector 18. The first electrode 14 is clamped and fixed to the inner support tube 34 on the proximal side of the balloon 10. Both the distal and proximal ends of the balloon 10 are fixed to the outer wall of the inner support tube 34 by bonding, high-strength fiber winding, welding, or heat sealing. The first wire 16 extends outside the balloon 10 and is connected to an external electrophysiological nerve signal monitoring device. The first metal buckle 20 is sleeved on the outer side of the distal end of the balloon 10, and the first metal buckle 20 fastens and fixes the distal end of the balloon 10 to the inner support tube 34. The second metal buckle 21 is sleeved on the outer side of the proximal end of the balloon 10, and the second metal buckle 21 fastens and fixes the proximal end of the balloon 10 to the outer support tube 35. The difference between the trigeminal ganglion compression device of this embodiment and the trigeminal ganglion compression device of Example 1 is that the support tube 30 has a different number of cavities. The structure and composition of the components such as the head 19 and the syringe 22 in the device are the same, and will not be repeated here.

[0048] Example 3

[0049] Please also see Figures 8 and 9 In this embodiment, the support tube 30 of the trigeminal ganglion compression device is a double-lumen tube, and the two cavities of the support tube 30 respectively form a fluid channel 31 and a wire channel 32, and a lead channel 182 is opened on the connecting piece 18; the fluid channel 31 is respectively connected to the balloon 10 and the injection cavity 181, and the wire channel 32 is connected to the lead channel 182.

[0050] Specifically, the support tube 30 includes an inner support tube 34 and an outer support tube 35. The inner support tube 34 is sleeved on the inner side of the outer support tube 35. The inner support tube 34 and the outer support tube 35 are sleeved to form a dual-lumen structure. The inner lumen of the inner support tube 34 serves as a fluid channel 31 and also serves as a guidewire channel. The gap between the inner support tube 34 and the outer support tube 35 forms another lumen, which serves as a guidewire channel 32. The inner support tube 34 is provided with a through hole 36. The contrast agent passes through the fluid channel 31 of the inner support tube 34 and then enters the capsule 10 through the through hole 36. In this embodiment, the support tube 30 forms a dual-lumen structure by sleeved with the inner support tube 34 and the outer support tube 35. In other embodiments, the support tube 30 can also be directly a dual-lumen tube, with one lumen of the dual-lumen tube serving as the fluid channel 31 and the other lumen serving as the guidewire channel 32. In actual applications, the specific structure of the support tube 30 can be selected according to actual needs and is not specifically limited in this embodiment.

[0051] In this embodiment, the first electrode 14 is clamped and fixed on the inner support tube 34 on the proximal side of the balloon 10. One end of the first wire 16 is connected to the first electrode 14, and the other end passes through the wire channel 32 and then through the lead channel 182 to extend to the outside of the connector 18, and is connected to the external electrophysiological nerve signal monitoring device. In this embodiment, the support tube 30 has a wire channel 32, and the connector 18 is provided with a lead channel 182. The first wire 16 passes through the wire channel 32 and then through the lead channel 182 to extend to the outside of the connector 18, which can effectively prevent the first wire 16 from being entangled or damaged, is beneficial to protecting the first wire 16 and is convenient to use. The difference between the trigeminal ganglion compression device of this embodiment and the trigeminal ganglion compression device of Example 2 is that the flow channel function of the cavity of the support tube 30 is different. Other structures, such as the structure and composition of the components such as the head 19 and the syringe 22 are the same as those of Example 1 and Example 2, and will not be repeated here.

[0052] Example 4

[0053] Please also see Figures 10 and 11 In this embodiment, the support tube 30 has three cavities, which respectively form a fluid channel 31, a wire channel 32, and a guidewire channel 33. The connector 18 is provided with a guidewire channel 182 and a guidewire through-hole 183. The fluid channel 31 is respectively connected to the balloon 10 and the injection cavity 181, the wire channel 32 is respectively connected to the guidewire channel 182, and the guidewire channel 33 is respectively connected to the balloon 10 and the guidewire through-hole 183. Specifically, the contrast agent is injected into the balloon 10 through the fluid channel 31. The first wire 16 passes through the wire channel 32 and then through the guidewire channel 182 to the outside of the connector 18. The guidewire channel 32 is for the guidewire to pass through. The fluid channel 31, wire channel 32, and guidewire channel 33 are independently provided, which further facilitates use. The difference between the trigeminal ganglion compression device of this embodiment and the trigeminal ganglion compression devices of Examples 1, 2 and 3 is that the support tube 30 has a different number of cavities. The structures and compositions of the components such as the head 19 and the syringe 22 in the device are the same and will not be repeated here.

[0054] The following is a detailed description of the use of the trigeminal ganglion compression device in Example 3. Specifically, the specific clinical operation of the trigeminal ganglion compression device in Example 3 is as follows:

[0055] First, after general anesthesia, the patient is placed in a supine position with a cloth roll of appropriate height placed under the shoulder to ensure slight extension of the neck. Then, under an X-ray environment, a channel is established approximately 2.5 cm from the corner of the mouth on the affected side with the help of X-ray imaging, and the balloon 10 is inserted. After the balloon 10 enters the semilunar ganglion of the trigeminal nerve in Meckle's cavity and is positioned, the second electrode 15 is attached to the patient's face, and the electrophysiological nerve signal monitoring device is used to measure the nerve signal before treatment; then, the diluted contrast agent is injected into the inner support tube 34 through the injection cavity 181 of the connector 18. The balloon 10 is inflated. At this time, the amount of diluted contrast agent injected can ensure that the Meckle's cavity is just filled. The filling shape of the balloon 10 is monitored in the lateral position through X-ray imaging, and the nerve signals during the treatment are monitored through an electrophysiological nerve signal monitoring device. During this process, the shape and position of the balloon 10 are continuously adjusted to keep the balloon 10 inflated and compress the trigeminal ganglion for 3 to 7 minutes. When the nerve signal difference value that achieves the best clinical treatment effect appears, the operation is successful. At this time, the contrast agent is extracted and the operation is completed.

[0056] The above-mentioned trigeminal ganglion compression device can be connected to an electrophysiological nerve signal monitoring device to monitor the size of the patient's trigeminal nerve pain nerve signal before and during surgery, so that the difference in nerve signals can be used to determine whether the treatment has achieved the expected pain-relieving effect. It can quantitatively evaluate the treatment effect, overcome the defect of uneven treatment effects caused by the lack of a quantitative parameter to evaluate treatment standards in clinical practice, and achieve the clinical effects of precise treatment, rapid treatment, improved prognosis, and reduced complications. It can effectively improve the cure rate of the disease and is conducive to the widespread promotion and application of trigeminal ganglion balloon compression technology.

[0057] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention.
