Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a cranioplasty perfusion device. Background Technology

[0002] Autologous cranioplasty is a common neurosurgical procedure that addresses abnormal cerebral blood supply, insufficient or impaired cerebrospinal fluid circulation, and brain compression caused by skull defects. In neurosurgical craniotomy, it is often necessary to remove a skull flap. If autologous cranioplasty is to be performed, the skull flap needs to be stored at low temperature. When the patient's condition is stable and cranioplasty is required, the autologous skull flap is reimplanted. Before reimplantation, the skull flap stored at low temperature is in a state of ischemia and hypoxia, which will affect its bone cells.

[0003] Currently, there is a lack of devices on the market specifically designed for the effective resuscitation and perfusion of isolated cranioplasty flaps. Existing methods for cleaning after cranioplasty mainly involve manually using two or more sterile basins filled with sterile saline solution for several washes. These simple methods cannot meet the requirements for maintaining the viability of cranioplasty flap cells and are inefficient for cranioplasty repair. Therefore, there is an urgent need for a device that can effectively resuscitate and perfuse cranioplasty flaps.

[0004] A craniotomy resuscitation and perfusion device is proposed to address the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a cranioplasty resuscitation irrigation device to solve the problem mentioned in the background art. The existing cleaning methods for cranioplasty are mainly manual, using two or more sterile basins filled with sterile saline solution for several washes. These simple methods cannot meet the requirements for maintaining the activity of cranioplasty cells and have low efficiency for cranioplasty repair.

A liquid inlet pipe is fixedly connected between the top of the insulated box and the inner liner. A valve exhaust pipe is fixedly connected to the side of the insulated box and the inner liner near the liquid inlet pipe.

A micro peristaltic pump is fixedly installed at the center of the top of the workbench. A suction tube is fixedly connected to one side of the micro peristaltic pump between the insulated box and the inner liner. An inlet pipe is fixedly connected to the output end of the micro peristaltic pump between the hollow box and the hollow box. A connecting pipe is fixedly connected between the bottom of the hollow box and the end cap. A shower head is fixedly installed at the bottom of the connecting pipe. A temperature sensor and a pressure sensor are fixedly installed on the inner side of the top of the glass box.

[0008] Preferably, the glass box has symmetrically fixed boxes installed on its inner side, and fixed frames are provided between the boxes. Rotating shafts are symmetrically fixed on both sides of the fixed frames, and one end of the rotating shaft passes through the box and is rotatably connected to the box. A forward and reverse motor is fixedly installed inside the box, and the output end of the forward and reverse motor is fixedly connected to the rotating shaft. Fixed tubes are symmetrically fixed on the inner side of the fixed frames, and a pressing rod is slidably connected inside one end of the fixed tube.

Guide rods are symmetrically fixedly installed on the top of the rubber plate, and the top of the guide rods penetrates the clamping plate and is slidably connected to the clamping plate. A stop block is fixedly installed on the top of the guide rods.

[0010] Preferably, a liquid outlet pipe is embedded on one side of the bottom of the glass box.

[0011] Preferably, the sealing assembly includes a rotating seat, and the rotating seats are symmetrically fixedly installed on both sides of the end cover. A rotating plate is rotatably connected to the inner side of the rotating seat, and a groove is provided on one side of the rotating plate. Protrusions are symmetrically fixedly connected to both sides of the top of the glass box, and the inside of the groove and the outside of the protrusion are fastened together. A fixing knob is threadedly connected between the rotating seat and the rotating plate.

[0012] Preferably, a sealing plug is fitted to the inner side of the top of the liquid addition tube.

[0013] Preferably, a frame-shaped sealing gasket is fixedly installed at the bottom of the end cap, and the outer side of the frame-shaped sealing gasket is fitted with the inner side of the glass box with a clearance.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: A cranial flap resuscitation irrigation device is described, in detail, as follows: A micro-peristaltic pump, activated by a worker, draws irrigation fluid from the inner chamber through a suction tube. The fluid then enters the hollow box through an inlet pipe and is sprayed downwards through multiple connecting pipes and a shower head, ensuring even coverage of the cranial flap surface. Temperature and pressure sensors monitor the temperature and pressure within the glass box in real time, enabling precise control of the irrigation fluid's temperature, flow rate, and pressure. This simulates the human physiological environment, providing excellent resuscitation conditions for the isolated cranial flap. It effectively maintains the activity of the cranial flap's bone cells, improves the survival rate after reimplantation, and reduces the incidence of postoperative complications such as bone flap necrosis and infection. This significantly improves the efficiency of cranial flap repair and cleaning, reduces the workload of workers, and allows the worker to place the cranial flap between the inner sides of the splints, thus placing the compression rod inside the fixation tube. As the slide proceeds, the contraction spring contracts, utilizing its extension and restoring properties to continuously press the two sets of clamps inward to fix the skull flap. A rotating shaft, driven by a forward and reverse motor, rotates the two sets of clamps synchronously in the same direction, enabling rapid flipping of the skull flap. This allows for quick fixation of the skull flap inside the glass case, and allows staff to flexibly adjust the fixation according to the size of the skull flap. Staff can also flip the skull flap based on its cleaning and resuscitation progress, greatly improving flexibility during cleaning and resuscitation. The staff rotates the two sets of rotating plates inside the rotating seat. When the rotating plates reach a certain angle, the grooves and protrusions engage. Tightening the fixing knob limits the rotation of the plates, achieving rapid assembly and fixation between the end cap and the glass case. This ensures the stability and sealing of the glass case during use, preventing the end cap from detaching due to external impacts.

[0015] 1. The process involves staff activating a miniature peristaltic pump to draw irrigation fluid from the inner chamber through a suction tube. The fluid then enters the hollow box via an inlet pipe and is sprayed downwards through multiple connecting pipes and a shower head, ensuring even distribution across the skull flap surface. Temperature and pressure sensors monitor the temperature and pressure within the glass box in real time, allowing for precise control of the irrigation fluid's temperature, flow rate, and pressure. This simulates the human physiological environment, providing optimal resuscitation conditions for the isolated skull flap. It effectively maintains the activity of bone cells in the skull flap, improves the survival rate after reimplantation, and reduces the incidence of postoperative complications such as bone flap necrosis and infection. This significantly improves the efficiency of skull flap repair and cleaning, reduces staff workload, and ensures the quality of the irrigation fluid and the stability of the irrigation process through the double-layer sealing and insulation design of the insulated box, minimizing the impact of external factors on the irrigation effect.

[0016] 2. The staff places the skull flap between the inner sides of the splints. The spacing of the splints is adjusted according to the size of the skull flap, allowing the compression rod to slide inside the fixation tube. At this point, the compression spring contracts, and its extension and return properties allow the two sets of splints to continuously compress inwards, fixing the skull flap. After the irrigation fluid has cleaned the top side of the skull flap, the staff starts the forward and reverse motors to drive the rotation of the shaft. The rotation of the shaft causes the two sets of splints to rotate synchronously in the same direction, quickly flipping the skull flap and achieving rapid fixation inside the glass box. The staff can flexibly adjust the fixation according to the size of the skull flap. It can also be flipped over according to the cleaning and resuscitation of the skull flap, which greatly improves the flexibility of skull flap cleaning and resuscitation and brings convenience to the staff. The staff rotates two sets of screws inside the clamping plate. The rotation of the screws drives the rubber plate to move up and down. At this time, the rubber plate drives the guide rod to slide inside the clamping plate. The guide rod is limited by the stop block. At this time, the rubber plate can be flexibly adjusted and fixed according to the thickness of the skull flap, which can further improve the stability of the skull flap when placed inside the glass box. It can effectively prevent the skull flap from shifting and falling off during the perfusion resuscitation process, greatly improve the efficiency of the device and bring practicality to the staff.

[0017] 3. The staff places the end cap on top of the glass case. At this time, the frame-shaped sealing gasket is compressed and deformed, and then the frame-shaped sealing gasket is inserted into the inner side of the top of the glass case. The staff then rotates the two sets of rotating plates inside the rotating seat. When the rotating plates rotate to a certain angle, the groove and the protrusion engage. The staff then tightens the fixing knob to limit the rotation of the plates, thereby achieving the effect of quick assembly and fixation between the end cap and the glass case. This ensures the stability and sealing of the glass case during use, avoids the phenomenon of the end cap falling off due to external force collisions, and brings convenience to the staff during use.

An outlet pipe 227 is embedded on one side of the bottom of the glass box 205. The liquid is collected through the outlet pipe 227. A flow control valve is installed on the outlet pipe 227 to adjust the liquid outflow rate as needed to ensure a stable liquid level in the chamber.

[0030] Working principle: Before using this craniotomy resuscitation and perfusion device, it is necessary to check the overall condition of the device to ensure that it can function normally. Figure 1 - Figure 5As shown, the perfusion fluid is first poured into the inner tank 202 through the filling pipe 203. The inner tank 202 is made of medical-grade polycarbonate, which has good chemical stability and corrosion resistance, effectively preventing contamination of the perfusion fluid. The polyurethane foam filling inside the insulated box 201 maintains the perfusion fluid within a suitable temperature range (35-37℃), close to human body temperature, providing a favorable physiological environment for the cranioplasty. A one-way valve installed in the vent pipe 204 prevents outside air from entering and contaminating the perfusion fluid, while ensuring the fluid's stability. Once the internal pressure is balanced, the operator activates the micro-peristaltic pump 208, which drives the suction tube 209 to draw irrigation fluid from inside the inner liner 202. The operator can precisely control the flow rate of the irrigation fluid by adjusting the speed of the peristaltic pump, with a flow rate adjustment range of 5-20 mL / min to meet the irrigation needs of the skull flap in different surgical scenarios. The irrigation fluid then enters the hollow box 207 through the inlet pipe 210, and is then sprayed from top to bottom through multiple connecting pipes 211 and a shower head 212, ensuring the irrigation fluid is evenly sprayed onto the surface of the skull flap. Temperature sensor 213 and pressure sensor 214 monitor the temperature and pressure inside the glass chamber 205 in real time. Temperature sensor 213 transmits the monitored data to the temperature controller. When the temperature deviates from the set range (35-37℃), the temperature controller automatically activates the heating or cooling device for adjustment. Pressure sensor 214 transmits the pressure data to the pressure controller. When the pressure inside the glass chamber 205 is too high or too low, the pressure controller regulates the pressure inside the glass chamber 205 by controlling the opening and closing of the exhaust valve and the intake valve, maintaining it within the normal physiological pressure range (8-1). The temperature, flow rate, and pressure of the perfusion fluid can be precisely controlled (2 mmHg), simulating the physiological environment of the human body. This provides good resuscitation conditions for the isolated cranial flap, effectively maintaining the activity of the cranial flap bone cells, improving the survival rate after reimplantation, reducing the incidence of postoperative complications such as bone flap necrosis and infection, greatly improving the efficiency of cranial flap repair and cleaning, and reducing the workload of staff. The double-layer sealing and heat preservation design of the 201 insulated box ensures the quality of the perfusion fluid and the stability of the perfusion process, reducing the impact of external factors on the perfusion effect.

[0031] The staff places the skull flap between the inner sides of the splints 222. The spacing of the splints 222 is adjusted according to the size of the skull flap, allowing the compression rod 220 to slide inside the fixing tube 219. At this time, the contraction spring 221 contracts, and its extension and return properties allow the two sets of splints 222 to continuously compress inwards, fixing the skull flap. After the irrigation fluid has cleaned the top side of the skull flap, the staff starts the forward and reverse motor 218, driving the rotating shaft 217 to rotate. The rotation of the rotating shaft 217 causes the two sets of splints 222 to rotate synchronously in the same direction, achieving rapid flipping of the skull flap. This allows for quick fixation of the skull flap inside the glass box 205. The staff can flexibly adjust the fixation according to the size of the skull flap and can also flip it according to the cleaning and recovery status, greatly improving the flexibility of skull flap cleaning and recovery and providing convenience for the staff. The staff also rotates the two sets of screws 223 inside the splints 222. The rubber plate 224 moves up and down, causing the guide rod 225 to slide inside the clamp 222. The guide rod 225 is limited by the stop block 226. The rubber plate 224 is flexibly adjusted and fixed according to the thickness of the skull flap, which can further improve the stability of the skull flap when placed inside the glass box 205. It can effectively prevent the skull flap from shifting and falling off during the perfusion resuscitation process, greatly improving the efficiency of the device and bringing practicality to the staff. The liquid outlet pipe 227 is used to collect the liquid after perfusion. The liquid outlet pipe 227 is equipped with a flow control valve, which can adjust the liquid outflow speed as needed to ensure the stability of the liquid level of the perfusion fluid in the chamber. The design of the sealing plug 228 makes it easy for the staff to replenish the perfusion fluid in the inner liner 202. The frame-type sealing gasket 229 is closely connected to the glass box 205 to ensure the sealed environment in the chamber and prevent the perfusion fluid from leaking and external contamination. The liquid inlet pipe 210 uses medical-grade silicone tubing, which has good flexibility and biocompatibility.

[0032] The staff places the end cap 206 on top of the glass box 205. At this time, the frame-shaped sealing gasket 229 is compressed and deformed, and then the frame-shaped sealing gasket 229 is inserted into the inner side of the top of the glass box 205. The staff then rotates the two sets of rotating plates 302 inside the rotating seat 301. When the rotating plate 302 rotates to a certain angle, the groove 303 and the protrusion 304 engage. The staff then tightens the fixing knob 305 to limit the rotation plate 302, thereby achieving the effect of quick assembly and fixing between the end cap 206 and the glass box 205. This ensures the stability and sealing of the glass box 205 during use, avoids the phenomenon of the end cap 206 falling off due to external force collisions, and brings convenience to the staff during use.
