Technical Field
[0001] The present invention relates to the technical field of medical devices, and in particular to a visualized cerebral hematoma removal device and a hematoma removal system. Background Art
[0002] Spontaneous cerebral hemorrhage refers to the formation of hematoma in the brain parenchyma after blood breaks through intracranial blood vessels due to non-traumatic reasons. It is a common and frequently occurring disease in neurosurgery, especially basal ganglia cerebral hemorrhage. Cerebral hemorrhage accounts for 17.1%-55.4% of all strokes, with an acute mortality rate of up to 30%-40%. The prognosis is extremely poor, with extremely high mortality and disability rates.
[0003] At present, the treatment of hypertensive cerebral hemorrhage in clinic mostly adopts craniotomy to remove hematoma and intracerebral hematoma puncture. The former has the disadvantage that the surgical trauma is large, especially the treatment of deep hematoma, which causes damage to important neural structures in the brain to varying degrees, with high mortality and disability rates. Craniotomy to remove hematoma requires good medical equipment conditions, high cost, great pain for patients, and strict requirements on the patient's physical condition. Many elderly and frail patients die due to poor physical conditions and lose the opportunity for craniotomy. The latter is that when the patient's intracerebral hematoma is soft in texture, with the help of intracerebral hematoma puncture tube, only part of the hematoma can be drawn out, and there is a problem of low hematoma drainage efficiency. The drainage of intracranial hematoma still needs to be judged by reexamination of cranial CT. Moreover, intracerebral hematoma puncture generally needs to wait for 6 hours after the onset of the disease before the patient's bleeding stabilizes, and the damage to important brain structures within 6 hours significantly increases the patient's disability and mortality rate.
[0004] At present, CN116616860A discloses a minimally invasive visual shaftless spiral intracranial hematoma remover and an intracranial hematoma removal method. This solution adjusts the negative pressure attraction force of an external negative pressure suction device to avoid damage to brain tissue caused by excessive suction.
[0005] However, the above scheme lacks the function of manually adjusting the negative pressure suction, which limits the precise adjustment of the suction effect. Medical staff cannot flexibly adjust the treatment strategy according to the specific characteristics of different patients and hematomas, which may lead to unsatisfactory treatment effects.

[0029] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content. Example
[0030] The present invention discloses a visual cerebral hematoma removal device and a hematoma removal system. Figure 1 and Figure 2 As shown, the visualized cerebral hematoma removal device includes an operating handle 1 and a composite tube 2 arranged on the operating handle 1, the composite tube 2 includes an outer pipe 201, one end of the outer pipe 201 is connected to an integrated terminal 202, the interior of the integrated terminal 202 is provided with a flushing port 203 and a suction port 204, the interior of the outer pipe 201 is provided with a flushing pipe 205 and a suction pipe 206, specifically, one end of the flushing pipe 205 passes through the operating handle 1 and the interior of the outer pipe 201 in sequence and penetrates the flushing port 203 in the integrated terminal 202, the other end of the flushing pipe 205 is connected to a flushing assembly 3, one end of the suction pipe 206 passes through the operating handle 1 and the interior of the outer pipe 201 in sequence and penetrates the suction port 204 in the integrated terminal 202, the other end of the suction pipe 206 is connected to a negative pressure suction pipe 4, and the negative pressure generated by the negative pressure suction pipe 4 forms a first air path inside the suction pipe 206.
[0031] like Figure 1 As shown, the connection method between the operating handle 1 and the composite tube 2 is not limited to threaded connection and snap connection, but can also include other various detachable connection methods. Various connection methods allow users to choose the most suitable connection method according to specific application scenarios and needs, thereby improving the applicability and flexibility of the equipment. Moreover, the detachable connection method makes the disassembly and assembly of the equipment more convenient, facilitates daily maintenance and cleaning, improves operating efficiency, and reduces maintenance costs. In addition, if a part of the operating handle 1 and the composite tube 2 is damaged or needs to be improved, the user can easily replace it without having to replace the entire device.
[0032] like Figure 3As shown, an adjustment hole 5 is provided on one side surface of the operating handle 1 , and the adjustment hole 5 of the operating handle 1 is connected to the suction tube 206 through a connecting tube 6 , and the negative pressure generated by the negative pressure suction tube 4 forms a second air path inside the connecting tube 6 and the suction tube 206 .
[0033] like Figure 3 As shown, when adjusting the negative pressure of the negative pressure suction tube 4, the air circuit system is divided into two independent channels, the first air circuit and the second air circuit. When the adjustment hole 5 is in a closed state, the first air circuit will maintain normal operation. When the medical staff releases their fingers, the second air circuit is connected to the external environment. At this time, the outside is in a positive pressure state and the suction tube 206 cavity maintains a negative pressure. The entry of the external positive pressure partially offsets the negative pressure in the tube, thereby achieving the adjustment of the negative pressure in the suction tube 206. By manually adjusting the opening size of the adjustment hole 5, the medical staff can control the negative pressure suction in real time to accurately adjust the suction effect.
[0034] like Figure 3 As shown in the figure, the design has a simple structure, is easy for medical staff to operate, and provides a more intuitive user experience. Compared with the traditional method of manually adjusting negative pressure through a mechanical structure, medical staff often find it difficult to clearly perceive pressure changes during the adjustment process using a mechanical structure, and need to make adjustments and observe the effects at the same time.
[0035] like Figure 3 As shown, the suction pressure is adjustable, and the suction pressure can be adjusted according to different hematoma tissues, which can not only effectively remove the hematoma, but also protect the brain tissue from being damaged by the suction force.
[0036] like Figure 3 and Figure 4 As shown, the cross-section of the adjustment hole 5 is one of an ellipse, an oblong or a runway shape, and a linear adjustment path is formed by extending the long axis direction of the adjustment hole 5; compared with the circular hole, the design of the adjustment hole 5 can achieve a linear proportional relationship between the finger coverage position and the negative pressure suction force. The long axis size of the adjustment hole 5 is smaller than the operator's finger contact surface, and the continuous adjustment of the negative pressure gradient is achieved by dynamically changing the coverage area and the exposure area. This structure converts the physical stroke into a pressure control parameter, which is in line with the clinical operation intuition.
[0037] like Figure 3 As shown, a thrombus breaker is arranged inside the negative pressure suction tube 4. The thrombus breaker is connected to the brushless motor fixed in the operating handle 1 through a long axis. The thrombus breaker is located at the suction port 204 and hidden in the suction port 204. Compared with the traditional breaker arranged outside the suction port 204, this design effectively reduces the risk of damage to the surrounding brain tissue.
[0038] like Figure 3As shown, further, a switch 7 for controlling the power supply of the brushless motor is provided on the operating handle 1, and medical personnel can adjust the start and stop of the brushless motor through this switch 7. Driven by the adjustable speed brushless motor, the thrombus breaker can rotate, thereby achieving precise pulverization of the hematoma. This design is intended to improve the convenience of suction while effectively protecting the surrounding brain tissue and preventing it from being damaged.
[0039] like Figure 3 As shown, a conical buffer cavity 9 is provided inside the connecting pipe 6, and the narrow end of the regulating hole 5 is close to and faces the regulating hole 5; based on the Venturi tube principle, when the fluid flows from the narrow end into the larger conical buffer cavity 9, a better transition effect can be provided to avoid turbulence and further pressure fluctuations. The dual gas path parallel design can effectively avoid pressure fluctuation interference, especially during rapid adjustment.
[0040] like Figure 3 As shown, the adjustment hole 5 and the switch 7 are arranged in a spatially isolated manner, and the two are placed in different geometric planes, such as orthogonal planes or stepped planes. Tactile identification isolation is achieved through the physical height difference or axial offset of the operating interface. This design complies with the anti-mistouch principle of human-computer interaction and ensures that only a single control element exists in a single operating plane.
[0041] like Figure 3 As shown, specifically, the plane where the adjustment hole 5 is located forms an angle of ≥30° with the plane where the switch 7 is located, and a functional partition mapping relationship is established based on ergonomics. During the axial movement of the finger, it is necessary to cross the plane boundary threshold, specifically a height difference of 5-8mm, to trigger the corresponding operation, which significantly reduces the probability of false triggering caused by parallel operation.
[0042] like Figure 1 and Figure 2 As shown, the operating handle 1 is provided with a lens module 8 inside, and the lens module 8 includes a cable channel arranged inside the operating handle 1 and an endoscope lens 801 arranged inside the integrated terminal 202. A cable assembly is arranged inside the cable channel of the operating handle 1, and one end of the cable assembly is electrically connected to the endoscope lens 801, and the other end of the cable assembly is connected to an aviation connector video cable 802. The aviation connector video cable 802 is connected to an external host, and the host is connected to a display. Thus, real-time image transmission and display are achieved. This design not only enhances the visualization effect during surgery, but also improves the accuracy and safety of the operation, allowing medical staff to observe the surgical area more clearly, thereby making more accurate decisions and operations.
[0043] like Figure 1 and Figure 2 As shown, specifically, the display used can be a high-definition display device such as 4K, or a flexible and mobile small display device such as IPAD, which has the advantages of clear display and convenience and flexibility.
[0044] like Figure 5 As shown, the flushing component 3 includes a connecting tube 301, one end of which is connected to the flushing tube 205, and the other end of the connecting tube 301 is connected to a manual pressurizer 302, through which the flushing liquid is pumped into the flushing tube 205. The design of the manual pressurizer 302 allows the operator to flexibly control the pressure of the flushing liquid as needed, thereby effectively realizing the adjustment of the liquid flow rate in the flushing tube 205.
[0045] like Figure 5 As shown, a pressure gauge 303 and a flow control valve 304 are provided on the connecting pipe 301. The pressure gauge 303 is used to monitor the pressure in the connecting pipe 301 in real time. It senses the pressure of the fluid in the pipeline and displays it. The feedback pressure information can help the operator understand the current working state of the system and ensure that the system operates within a safe pressure range. The flow control valve 304 is used to control the flow amount of the fluid. By adjusting the opening of the valve, the flow rate of the fluid through the pipeline can be changed, thereby achieving accurate control of the flow rate of the flushing liquid. The flow control valve 304 is usually in the form of a knob or a lever, which can be adjusted conveniently and quickly.
[0046] like Figure 5 As shown, the operator can precisely control the flushing process, including adjusting the pressure and flow of the liquid, through the pressure gauge 303 and the flow regulating valve 304, so as to achieve the best flushing effect. Through the flushing tube 205, slight tissue debris can be effectively removed by flushing liquid.
[0047] like Figure 6 As shown, based on the above-mentioned visualized cerebral hematoma removal device, the visualized cerebral hematoma removal system includes: S1: gas circuit adjustment module; When adjusting the negative pressure of the negative pressure suction tube 4, the gas circuit system is divided into two independent channels, the first gas circuit and the second gas circuit. When the adjustment hole 5 is in a closed state, the first gas circuit will maintain normal operation.
[0048] When the medical staff releases their fingers, the second air circuit is connected to the external environment, at which time the external environment is in a positive pressure state while the negative pressure is maintained in the cavity of the suction tube 206. The entry of the external positive pressure partially offsets the negative pressure in the tube, thereby achieving the regulation of the negative pressure in the suction tube 206.
[0049] Medical staff can control the negative pressure suction force in real time by manually adjusting the opening size of the adjustment hole 5 to accurately adjust the suction effect. Specifically, the adjustment hole 5 adopts an elliptical, oblong or runway-shaped cross-section design, and forms a 12-15mm linear adjustment path in the long axis direction. Compared with a circular hole, its advantages are: the dynamic ratio of the coverage area to the exposure area is more consistent with the finger movement trajectory; its long axis size is smaller than the contact surface of an adult's fingertip, ensuring full adjustment.
[0050] A conical buffer chamber 9 (with a diameter of 2 mm at the narrow end and 8 mm at the expanded end) is provided in the connecting pipe 6, and the principle of fluid dynamics is used to achieve: the instantaneous pressure difference fluctuation when the two gas paths are connected in parallel is controlled within ±5 kPa.
[0051] S2: intelligent suction module; A thrombus crusher hidden in the suction port 204 is used, wherein the thrombus crusher adopts a titanium alloy spiral crushing head with a diameter of 1.2mm and an adjustable speed range of 500-5000rpm, and is driven by a brushless motor; and with the help of a flushing tube 205 and a suction tube 206, the function of clearing and suctioning cerebral hematoma is achieved.
[0052] S3: tissue protection module; The adjustment hole 5 and the motor switch 7 are designed to be isolated in an orthogonal plane (angle ≥30°, height difference 5-8mm), and the tactile feedback difference is used to reduce the error operation rate.
[0053] S4: high-definition visualization module; T1. Endoscopic imaging unit; The integrated terminal 202 has a built-in ultra-miniature endoscope lens 801 with a diameter of 0.8 mm. The endoscope lens 801 has a resolution of 1280×720 and a field of view of 120°. When used with a 4K display on an external host, it can achieve a tissue recognition accuracy of 50μm and a clearly visible vascular network. The real-time delay is <80ms, meeting the needs of dynamic surgery. It also supports white light / fluorescence dual-mode switching to enhance lesion identification.
[0054] T2. Modular transmission unit: The military-grade 10Gbps aviation connector video cable 802 is used, which has an anti-electromagnetic interference capability of 60dB, ensuring signal stability in the complex environment of the operating room; it is also compatible with the DICOM standard and supports image archiving and postoperative analysis.
[0055] S5: Precision flushing control module; T1. Manual mechanical coordinated adjustment; The flushing component 3 includes a manual pressurizer 302 with a maximum output pressure of 300 mmHg and a flow regulating valve 304 with an adjustment accuracy of ±2 mL / min, which are used to dynamically achieve the flushing effect.
[0056] T2. Fluid dynamics optimization; The inner wall of the flushing pipe 205 is provided with a spiral groove. The design of the spiral groove enables the flushing liquid to form a swirl effect, thereby increasing the debris suspension rate by 40% and reducing the need for secondary suction; the uniformity of flow field distribution is improved, and the edge area coverage rate reaches 95%; the fluid resistance is reduced by 28%, and the flow rate is increased by 1.5 times under the same pressure.
[0057] Through mechatronic design, fluid dynamics optimization and ergonomics innovation, this system has built a brain hematoma removal solution that integrates precise control, real-time visualization and safety assurance, setting a new technical benchmark for minimally invasive neurosurgery.
[0058] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
