Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically, it relates to a device system for minimally invasive hematoma evacuation in cerebral hemorrhage. Background Technology

[0002] Hypertensive intracerebral hemorrhage is a common type of hemorrhagic stroke. Intracerebral hemorrhage has become a serious killer affecting the health of Chinese residents. After an intracerebral hemorrhage, the treatment goals of hematoma evacuation surgery are to quickly and effectively remove the hematoma, reduce or avoid intracranial hypertension caused by the hematoma, and reduce or block the secondary reaction of the hematoma to surrounding normal brain tissue. However, any hematoma evacuation surgery will inevitably cause some degree of collateral damage or complications to normal brain tissue. Therefore, minimizing surgical collateral damage or complications and making the surgery as minimally invasive as possible while evacuating the hematoma is a long-term goal that neurosurgeons should relentlessly pursue.

[0003] In recent years, surgical treatment of cerebral hemorrhage has achieved satisfactory results, leading to the development of major surgical methods such as minimally invasive hematoma puncture and drainage, microscopic hematoma evacuation, and endoscopic hematoma evacuation under endoscopic illumination via cortical stoma. While each of these methods has its own minimally invasive features, they also have inherent technical limitations. For example, while minimally invasive hematoma puncture and drainage does not require craniotomy and is relatively minimally invasive, it is difficult to manage and stop active bleeding during the procedure. Microscopic hematoma evacuation, which involves craniotomy and retraction of the cerebral cortex to the hematoma cavity, causes significant collateral damage to brain tissue. Endoscopic hematoma evacuation also faces challenges due to the limited working space; the endoscope, suction device, and bipolar electrocoagulator interfere with each other, greatly reducing the smoothness and operability of the procedure, especially in cases of active bleeding where hemostasis is difficult, leaving the surgeon in a passive position. Summary of the Invention

[0022] Please refer to the following: Figures 1 to 8This invention provides an instrument system for minimally invasive hematoma evacuation in cerebral hemorrhage. The instrument system includes: a puncture tube 1, a puncture stylet 2, a dilator 3, a conformal working channel 4, a closing fork 5, and a suction device 6. The puncture tube 1 is hollow, with one end being a pointed tip and the other an open end. The pointed tip of the puncture tube 1 has a first side hole. The puncture stylet 2 is fitted to the puncture tube 1; the puncture stylet 2 is inserted into the puncture tube 1 to seal the hollow part of the puncture tube 1. The tip of the puncture stylet 2 gradually tapers to match the pointed tip of the puncture tube 1. The dilator 3 is used after the puncture tube 1 has successfully penetrated the hematoma cavity; it is fitted over the tail end of the puncture tube 1 and inserted into the hematoma cavity along the puncture tube 1; it also forms an artificial channel between the brain surface cortex and the normal brain tissue surrounding the puncture channel in the hematoma cavity, allowing subsequent working channels to enter the hematoma cavity. The conformal working channel 4 provides a working channel for the instruments during hematoma removal. The suction device 6 includes: a suction device body, a curved tube 62, a camera 63, and a lighting lamp 64. The suction device 6 integrates lighting, imaging, suction, and electrocoagulation hemostasis functions. Specifically, the curved tube 62 is set on the suction device body 61; the curved tube 62 includes a first segment 621, a second segment 622, and a third segment 623 connected in sequence, with the first segment 621 and the second segment 622 transitioning through an angled structure, and the second segment 622 and the third segment 623 transitioning through an angled structure; the camera 63 is set on the curved tube 62; the lighting lamp 64 is set on the curved tube 62.

[0023] In some feasible embodiments, the puncture mandrel 2 is shaped like a stainless steel rod. The puncture mandrel 2 is inserted into the hollow portion of the puncture tube 1 to seal the hollow part of the puncture tube 1. The puncture tube 1 is used to puncture the hematoma cavity through normal tissue. Its outer diameter is 0.5 cm, its inner diameter is 0.3 cm, and its total length is 14 cm. The thinnest part of the tip of the puncture tube 1 is 0.2 cm, with a 0.3 cm long side hole 1 cm from the tip. The very end is rounded. During use, the puncture mandrel 2 is inserted into the puncture tube 1 to puncture the hematoma. Once the hematoma cavity is reached, the puncture mandrel 2 is removed. The hematoma fluid flowing out from the end of the puncture tube 1 indicates a successful puncture.

[0024] In some feasible embodiments, the expansion tube 3 includes a first tube body 31 and a second tube body 32 connected to the first tube body 31. The diameter of the first tube body 31 gradually tapers from one end close to the second tube body 32 to the other end. Specifically, the expansion tube 3 has an inner diameter of 0.55 cm, an outer diameter of 1.4 cm, and a total length of 12 cm. The first tube body is 2 cm long, and its diameter gradually tapers from one end close to the second tube body to the other end. The second tube body is 10 cm long, and its diameter is a fixed value. The diameter of the second tube body is the same as the maximum diameter of the first tube body.

[0025] In some feasible embodiments, the conformal working channel 4 includes a hollow tube 41, a blade portion 42 connected to one end of the hollow tube 41, and a handle portion 43 disposed at the other end of the hollow tube 41, wherein the hollow tube 41 is cylindrical in shape. The blade portion 42 includes two symmetrically arranged blades, which act as pressure plates. Specifically, the conformal working channel 4 is used to ensure that the instrument does not touch the shape of the surrounding normal brain tissue when entering the hematoma cavity. The size of the conformal working channel 4 is designed to adapt to the shape of the expanded channel and / or the hematoma cavity.

[0026] In some feasible embodiments, the hollow tube 41 has an outer diameter of 1.4 cm, an inner diameter of 1.2 mm, a wall thickness of 1 mm, and a length of 9 cm. The front blade is 1.3 cm wide and 2 mm thick, and opens in a "(" shape. It is elastic and naturally opens in a "(" shape, and closes in a "()" shape. At this time, the lower ends of the two blades are set outward. The end handle is 2 cm long and extends to the side at a right angle. There is a longitudinal slit between the two blades. Under the action of the closing fork 5, the two blades can be closed. The lower ends of the two blades converge inward. After the closing fork 5 is withdrawn, the blades rely on their own elasticity to restore the "()" shape and open. At this time, the lower ends of the two blades are set outward.

[0027] In some feasible embodiments, the closing fork 5 is a metal fork-shaped structure, comprising a main body 51, fork fins 52 disposed at one end of the main body 51, and a handle 53 disposed at the other end of the main body. Specifically, the main body is 11cm long, with two fork fins at the front end, each 2cm long, and a 1.0cm gap between them. A handle, a ring-shaped handle, is provided at the end of the main body for easy gripping. Upon entering the working channel, the two fork fins pass through the two leaf-shaped slits from the inside out, closing the two leaf-shaped slits.

[0028] In some feasible embodiments, the bend 62 includes a first segment 621, a second segment 622, and a third segment 623. The angle between the first segment 621 and the second segment 622 is 120°; the angle between the second segment 622 and the third segment 623 is 120°. The length of the first segment 621 is 1.5 cm. The length of the second segment 622 is 15 cm. The length of the third segment 623 is 5 cm. The end of the first segment 621 facing away from the second segment 622 has a 1x2000 metal teardrop-shaped electrocoagulation bead structure 624, which can be used to electrocoagulate the rear end of the suction device outside the working channel of the monopolar electrosurgical unit to stop bleeding. The end of the first segment 621 near the second segment 622 extends laterally. The second segment 622 has a miniature camera 63 near the first bend. Two symmetrically distributed lighting lamps 64, spaced a certain distance from the camera 63, are provided on the second segment to provide a light source. The third section 623 is equipped with a side hole 625, through which medical personnel can adjust the suction strength. The third section 623 also features a control structure 65, which is connected to a camera 63 and a lighting lamp 64 via metal wires. The lighting lamp 64 provides illumination to the corresponding hematoma cavity within the conformal working channel 4. The camera 63 provides real-time images of the aforementioned space, which can be projected onto a monitor in the operating room via the control structure 65, allowing the surgeon to observe the display while performing the procedure.

[0029] When the electrocoagulation bead comes into contact with the severed end of the blood vessel that is bleeding actively, the power of the traditional monopolar electrosurgical unit is turned up to an appropriate level (usually around 10), allowing the electrosurgical head to contact the metal part of the multi-functional suction device outside the working channel, thus achieving electrocoagulation hemostasis.

[0030] In some feasible embodiments, the puncture tube 1 and the dilation tube 3 may be made of non-toxic, food-grade silicone material, which has a relatively hard texture.

[0031] In some feasible embodiments, the conformal working channel 4 can be made of non-toxic, food-grade, and sterile silicone material, possessing toughness, elasticity, and a two-blade structure that does not break when joined, and can return to its original initial state after the closure fork 5 is removed. The conformal working channel 4 is also transparent. Both the inner and outer surfaces of the conformal working channel 4 are smooth, and the edges of the two blades are rounded. These properties ensure minimal damage to surrounding normal brain tissue during puncture, expansion to form the fistula, and placement of the conformal working channel.

[0032] In some feasible embodiments, the outer surface of the puncture core 2 is a smooth surface, which can be achieved by treating the outer surface of the puncture core 2 with a hydrophobic material.

[0033] In any feasible embodiment, the surfaces of the puncture tube 1, puncture core 2, dilator 3, and conformal working channel 4 are all made of food-grade, non-toxic, heavy metal-free, and harmless high-molecular-weight silicone (such as PV) material, possessing toughness, transparency, and elasticity. These properties can be achieved through silicone modification experiments. Furthermore, the interiors and surfaces of all the aforementioned components are smooth and burr-free, with blunt, non-sharp edges. This ensures no damage to brain tissue during surgery. The puncture tube 1, puncture core 2, and dilator 3 are perfectly matched in size, allowing for easy and smooth sliding insertion and fitting together without gaps, thus preventing brain damage. The surfaces of the puncture tube 1, dilator 3, and conformal working channel 4 are all treated with a hydrophobic substance, resulting in smooth surfaces that effectively prevent damage to brain tissue during surgery.

[0034] The present invention provides a method for using an instrument system for minimally invasive hematoma evacuation in cerebral hemorrhage, comprising the following steps: After successful anesthesia, the patient lies supine on the operating table with their head positioned stably in the center of the skull. Routine disinfection and draping are performed. A longitudinal incision of approximately 15cm is made on the frontal side of the hematoma, 25cm inward from the hairline and lateral to the midline (this incision is commonly used in the basal ganglia region; for other lobar hematomas, the incision is made on the scalp closest to the hematoma while avoiding functional areas). The scalp is incised and retracted using a mastoid retractor to expose the skull. A burr hole is drilled, and a small flap peak approximately 2.5cm in diameter is milled off with a milling cutter, along with the dura mater, to expose the cerebral cortex. Electrocoagulation puncture point is established in the cerebral cortex, and the hematoma is punctured according to the direction and depth determined by the T-scan of the skull. The puncture tube 1, with a stylet 2 attached, is inserted into the hematoma. The stylet 2 is then removed; successful puncture is indicated by the outflow of hematoma fluid. The operator stabilizes the puncture tube 1 at the correct direction and depth with one hand, while using the other hand to place the dilator tube 3 over the puncture tube 1 and gently push the dilator tube 3 from the surface of the cerebral cortex into the hematoma cavity. This creates an artificial sinus tract from the surface of the cerebral cortex to the hematoma cavity. The assistant holds the dilator tube 3 still and inserts the two wings of the closing fork 5 from the rear end of the conformal working channel 4. The wings are inserted from the inside to the outside of the gap between the two blades, and the two blades are closed. The maximum diameter of the two closed blades is smaller than the diameter of the hollow tube 41. The working channel closed by the closing fork 5 is placed into the hematoma cavity (before this step, the assistant removes the dilator so that the sinus tract from the cortex to the hematoma cavity is not closed, thus facilitating the surgeon to place the conformal working channel 4). The closing fork 5 is removed, leaving the conformal working channel 4 in place.

[0035] After the conformal working channel 4 is inserted into the hematoma cavity, the operator inserts the suction device 6 into the working channel to begin suctioning and removing the hematoma. Simultaneous suction and irrigation with saline solution can be performed. If the hematoma is too large or too hard, it can be crushed and suctioned out using appropriate instruments. In cases of active bleeding, the electrocautery bead structure can be brought into contact with the bleeding point to the severed vessel end. A monopolar electrosurgical unit is then used to contact the metal part of the suction device outside the working channel to achieve electrocoagulation hemostasis. Specifically, the multi-functional suction device is moved so that the electrocautery bead touches the severed vessel end, and then a traditional monopolar electrosurgical unit is used to contact the part of the suction device outside the working channel. Through conductivity, the electrocautery bead causes electrocoagulation hemostasis. Essentially, the monopolar electrosurgical unit exerts its electrocoagulation effect through the electrocautery bead, except that the monopolar unit does not need to be inserted into the hematoma cavity; it works from the outside through the electrocautery bead. The central hematoma is suctioned first; the peripheral hematoma gradually flows into the center under pressure, and finally, all hematomas are removed. After the hematoma cavity is completely removed, the two lobes of the brain tissue on both sides of the hematoma are separated, forming a small space (to prevent the cavity from completely closing after the hematoma is removed). Under the guidance of camera 63 and illumination light 64, carefully observe the bottom and surrounding area of ​​the hematoma cavity for any bleeding. Carefully rinse with saline, apply pressure with cotton pads, or use electrocoagulation beads or other methods to reliably stop any active bleeding. Cover the surface of the hematoma cavity with hemostatic gauze or other materials, and the hematoma is then completely removed.

[0036] The surgeon holds the conformal working channel 4 steady with one hand, and with the other hand, inserts the closing fork 5 into the conformal working channel 4 again, and inserts the two wings of the closing fork 5 into the gap between the two blades of the conformal working channel 4, so that the two blades close together and the conformal working channel 4 and the closing fork 5 are removed.

[0037] The dura mater, skull fixation, and scalp suturing are the same as in traditional surgical methods, and will not be described in detail here.

[0038] This invention provides an instrument system for minimally invasive hematoma evacuation in cerebral hemorrhage. Compared with existing technologies, this invention's instrument system for minimally invasive hematoma evacuation in cerebral hemorrhage changes the traditional simple tubular structure used in endoscopic hematoma evacuation by setting a conformal working channel 4. The front end is designed with two elastic, symmetrical blades that close when entering the hematoma cavity and open naturally during hematoma evacuation. This design adapts and matches the shape and size of the tubular portion at the rear end to the shape and size of the cortical sinus tract and the hematoma cavity. This matching design has the following advantages: No existing surgical method can avoid creating a pathway from the normal cerebral cortex surface to the hematoma cavity before proceeding with the operation (microsurgical techniques use a brain retractor to retract the brain tissue from the cortex to the hematoma cavity, endoscopic hematoma removal involves cortical puncture followed by expansion, and stereotactic procedures involve puncturing the hematoma with a drainage tube). A sinus tract is formed by puncturing with puncture tube 1 and expanding with dilation tube 3. Then, a two-lobe structure is inserted into the hematoma cavity. Because the diameter of the two lobes is smaller than the diameter of the hollow tube 41 when closed, the two lobes are positioned in the center of the hematoma. The closing fork 5 is withdrawn to aspirate the hematoma. As the pressure at the center of the hematoma decreases, the two-lobe structure opens to both sides under its own elastic force, but always without damaging the surrounding brain tissue, until the hematoma slowly decreases and blood gradually concentrates towards the center. After the hematoma is completely removed, the two lobes return to their naturally open state, separating the two sides of the brain tissue like a brain retractor. Throughout the entire process, there is no additional damage to the surrounding brain tissue.

[0039] Due to the elasticity of the two-lobed structure, a space gradually appears as the hematoma is removed. This space is smaller than the inherent volume of the hematoma, and its size depends on the interaction between the elasticity of the lobed portion 42 and the pressure of the hematoma. When the space gradually becomes larger than the diameter of the hollow tube portion 41, it provides a larger operating space, facilitating blood flow. This space also facilitates the use of curved instruments such as forceps to break up the hematoma, or the use of cotton wool for compression. In short, the existence of this space greatly improves the convenience of the surgical procedure. The elasticity of the two lobes acts like a brain template, which is beneficial for the surgeon to check for any residual hematoma. With a simple endoscope, the tubular channel is used to aspirate the hematoma while gradually withdrawing from the working channel. This may leave hematoma residue or hide in the gap after the brain tissue closes (or the hematoma cavity collapses) after hematoma removal. However, with this patent, because the two lobes are elastically open, and the working channel is rotated during the operation, bleeding can be viewed and treated before the brain tissue on all four walls of the hematoma closes. The blade section 42 can be used in conjunction with the suction device 6 to fully utilize the working range of the suction device. The suction device 6 also integrates functions such as lighting, imaging, blood collection and drainage, and hemostasis, which can effectively avoid the drawbacks of multiple instruments interfering with each other in endoscopic surgery.

[0040] In the solution provided by this invention, if hemostasis is required, simply aspirate the blood, and when the active bleeding vessel ends are visible, move the aspirator 6 and use the electrocoagulation bead structure 624 to touch the bleeding point to complete hemostasis. The first segment 621 bends upward and extends straight out. This part extends outside the structure of the hollow tube 41 and continues to extend forward from between the two blades, with a range of motion far greater than the narrow space of a single endoscopic channel. The aspirator 6 integrates multiple functions, allowing surgical operations to be completed with a smaller working channel diameter. Therefore, the working channel of this patent has a tubular diameter of 1.4 cm, while the diameter of the traditional endoscopic tubular working channel is 1.8-2.0 cm. The solution provided by this application can be performed under more minimally invasive conditions.

[0041] In the solution provided by this invention, the conformal working channel 4 and the suction device 6 complement each other, and their combined use can better leverage their respective advantages. The surfaces of the puncture tube 1, the dilation tube 3, and the conformal working channel 4 are all smooth, causing no damage to brain tissue during use. The edges of the leaf portion 42 are rounded and smooth, also preventing damage to brain tissue during use.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.
