Description

TECHNICAL FIELD

[0001] The present application relates to a hematoma suction device and a method of use. BACKGROUND

[0002] Hypertensive cerebral hemorrhage is one of the most serious complications of hypertension, and is a common disease in neurosurgery. When the intracranial hematoma reaches a certain amount, it needs to be removed to save lives. The most common bleeding site of hypertensive cerebral hemorrhage is the basal ganglia region, followed by subcortical and thalamic hemorrhage, and cerebellar and brainstem hemorrhage are relatively rare. About 40% of hypertensive cerebral hemorrhage patients are accompanied by intraventricular hemorrhage, which is a risk factor for poor prognosis. The bleeding site is an important reference for selecting surgical methods. There are many surgical treatment options, including large bone flap or small bone window craniotomy hematoma removal, hematoma drilling drainage, stereotactic hematoma puncture drainage and neuroendoscopic hematoma removal. Bone flap craniotomy is traumatic, drilling, directional hematoma puncture and neuroendoscopic surgery are minimally invasive. Regardless of which scheme, the hematoma is often tough and suction is not moving. Especially in minimally invasive surgery, suction of immobile hematoma often leads to excessive residual hematoma, affecting prognosis. For example, when removing hematoma under a neuroendoscope, the hematoma is often tough and the head of the suction device cannot suck out the large blood clots. It is often necessary to use a tumor forceps and a bipolar clamp to crush the blood clots, which is time-consuming and laborious. Some scholars use a planer, which is relatively sharp and may cut brain tissue. It is often necessary to operate carefully and for a long time, so it is not commonly used. Apollo system is used internationally. Apollo system is a metal hole rod with a vibrating element inside. It breaks the post-hemorrhagic products in the metal rod through high-frequency vibration and prevents clogging. At the same time, energy is not transmitted to the tissue outside the device. This method can achieve the effect of clearing hematoma, but the device is expensive and complex in structure. Few are developed in China. Therefore, a hematoma suction device with simple structure, low cost, easy use, good performance and small risk of brain tissue damage is needed.

[0003] In Chinese patent: 201720199258.8, named: an intracranial hematoma breaking and suction device and an intracranial hematoma breaking and negative pressure suction device, it is recorded that it includes a sleeve, a negative pressure suction device and a rotating device, the rotating device is installed in the sleeve, the output end of the negative pressure suction device is connected with the sleeve, and the negative pressure suction device and the rotating device are located at both ends of the sleeve respectively.

[0004] As shown in the drawings of the patent 201720199258.8, the patent mainly utilizes the hematoma breaking device arranged on the rotating device to insert into the hematoma to directly break the hematoma, and then the broken hematoma is sucked out. The patent can achieve the effect of breaking and sucking the hematoma in principle, but the breaking mode of directly inserting the hematoma breaking device into the hematoma to break the hematoma is dangerous, the breaking process is uncontrollable, and the brain tissue of the patient is easily damaged.

[0036] As shown in the drawings, the positioning mechanism 1 is a Y-shaped positioner, which includes a positioning hoop 11 and a positioning ruler 12 connected with the positioning hoop 11. The positioning hoop 11 is a half-ring-shaped clamp made of metal. The positioning hoop 11 can be clamped on the head of a patient. In order to facilitate fixation and positioning, the positioning hoop 11 has a certain elasticity and toughness, so as to ensure that the positioning hoop 11 can be stably clamped on the head of the patient. In order to ensure the hygienic environment of the operation and save costs, the positioning hoop 11 should be made of a material that is easy to disinfect and does not rust, such as medical-grade stainless steel or medical titanium alloy. In this way, the positioning hoop 11 can be repeatedly disinfected and used, thereby saving costs. Figure 1 5 The positioning ruler 12 includes a first positioning ruler 13 and a second positioning ruler 14 arranged in a cross shape. The first positioning ruler 13 is a rectangular metal ruler with a thickness of 3 mm, which ensures that the first positioning ruler 13 will not deform under weight during use.

[0037] The positioning ruler 12 includes a first positioning ruler 13 and a second positioning ruler 14 arranged in a cross shape. The first positioning ruler 13 is a rectangular metal ruler with a thickness of 3 mm, which ensures that the first positioning ruler 13 will not deform under weight during use. One end of the first positioning ruler 13 is welded to the outer side of the middle part of the positioning hoop 11, and the first positioning ruler 13 is perpendicular to the outer side of the positioning hoop 11. The first positioning ruler 13 is made of a material that is easy to disinfect and does not rust, such as medical-grade stainless steel or medical titanium alloy. Identical length scales are arranged on the surface of the first positioning ruler 13, and the starting value of the scales starts from the welding position of the first positioning ruler 13 and the positioning hoop 11.

[0038] ​​In order to facilitate the positioning of the positioning mechanism 1, a laser positioning table 17 for fixing the middle line laser corrector 18 is further arranged on the first positioning ruler 13. The laser positioning table 17 is a half-arc-shaped fixing clamp provided with a rectangular platform. The half-arc-shaped fixing clamp extends in the length direction of the first positioning ruler 13. Rectangular grooves are formed in the side surfaces of the two ends of the rectangular platform and pass through the rectangular platform. The laser positioning table 17 can be sleeved on the first positioning ruler 13 through the rectangular grooves. The laser positioning table 17 is detachably fixed on the first positioning ruler 13 through the screws arranged at the bottom of the laser positioning table 17.

[0039] The middle line laser corrector 18 comprises a cross laser pen and a laser pen sleeve. The cross laser pen is used to align the puncture guide lines on the horizontal surface and the puncture surface of the positioning mechanism 1, so as to realize the accurate positioning of the puncture point. The use is convenient.

[0040] In order to ensure the sterile environment during the operation and the cross laser pen cannot be subjected to high-temperature disinfection, in order to facilitate the fixation and packaging of the cross laser pen, a circular laser pen sleeve is clamped in the laser positioning table 17. A glass is embedded in one end of the laser pen sleeve to close the laser pen sleeve. The cross laser pen is inserted into the laser pen sleeve and the other end is closed. A button for facilitating the switch of the cross laser pen is arranged at the other end of the laser pen sleeve. The switch of the cross laser pen in the laser pen sleeve can be controlled through the button.

[0041] Definition: the surface with scales marked on the first positioning ruler 13 is the upper surface, and the surface opposite to the upper surface is the lower surface.

[0042] The second positioning ruler 14 is fixed on the second positioning ruler 14 through a detachable positioning clamp 15. The positioning clamp 15 is a rectangular metal block. Two rectangular grooves perpendicular to the positioning clamp 15 are formed in the side surface of the positioning clamp 15 and pass through the positioning clamp 15. The first positioning ruler 13 and the second positioning ruler 14 can be inserted into the rectangular grooves of the positioning clamp 15. In order to facilitate the fixation of the first positioning ruler 13 and the second positioning ruler 14, the two cross-distributed rectangular grooves are communicated. The upper surface of the first positioning ruler 13 and the lower surface of the second positioning ruler 14 are in contact in the positioning clamp 15. A threaded hole is formed in the lower surface of the positioning clamp 15 and a fixing screw 19 is screwed in the threaded hole. The top end of the fixing screw 19 is in contact with the lower surface of the first positioning ruler 13. The position of the positioning clamp 15 and the second positioning ruler 14 can be arbitrarily adjusted and fixed by screwing or unscrewing the fixing screw 19. In order to facilitate the observation of the scales of the second positioning ruler 14 inserted into the positioning clamp 15, a circular observation hole is formed in the upper surface of the positioning clamp 15 and perpendicular to the positioning clamp 15. The scales of the second positioning ruler 14 inserted into the positioning clamp 15 can be observed through the observation hole.

[0043] The second positioning ruler 14 is a rectangular metal ruler with a thickness of 3 mm and will not be deformed due to weight in use. The surface of the second positioning ruler 14 is uniformly provided with scales, the scale division value of which can be millimeters, or can be appropriately enlarged or refined according to actual needs. The second positioning ruler 14 can be inserted into the rectangular slot on the positioning card 15. A long circular hole 16 penetrating the second positioning ruler 14 is vertically formed on the second positioning ruler 14 near the beginning of the scale of the second positioning ruler 14. The adjusting sleeve 21 fixing the suction tube 22 is fixed on the second positioning ruler 14 by a screw.

[0044] As shown in Figure 1 and 5 , the adjusting sleeve 21 is a circular tube welded on a rectangular platform. The hematoma suction device 2 is inserted into the adjusting sleeve 21. A threaded hole is vertically formed on the lower surface of the rectangular platform of the adjusting sleeve 21. The adjusting sleeve 21 is fixed at the long circular hole 16 on the second positioning ruler 14 by a screw. In order to enhance the fixing effect, a gasket is placed between the screw and the adjusting sleeve 21. After the second positioning ruler 14 is fixed on the first positioning ruler 13, the position of the hematoma suction device 2 can be finely adjusted through the long circular hole 16.

[0045] In order to facilitate the adjustment and fixation of the position of the hematoma suction device 2 in the longitudinal direction, the diameter of the adjusting sleeve 21 is slightly larger than the diameter of the suction tube 22. A threaded hole is vertically formed on the surface of the adjusting sleeve 21. A screw threaded in the threaded hole can fix the suction tube 22 in the adjusting sleeve 21, thereby achieving the adjustment and fixation of the position of the hematoma suction device 2 in the longitudinal direction.

[0046] As shown in Figure 2 and 4 , the hematoma suction device 2 includes a suction tube 22, a breaker 23 and an adjusting knob 24.

A convex lens head 25 is embedded at the port of one end of the suction tube 22. When puncturing, a neuroendoscope can be inserted into the suction tube 22 to real-time view the puncturing process through the neuroendoscope and the convex lens head 25, thereby ensuring the accuracy of puncturing. The convex lens head 25 seals the port of the suction tube 22, thereby preventing blood from flowing into the suction tube 22 from the interface of the convex lens head 25.

[0047] In order to facilitate the breaking and suction of the hematoma, a suction and breaking port 26 is opened on the suction and breaking tube 22, near the end embedded with the convex lens head 25, 5mm from the end, penetrating the single wall of the suction and breaking tube 22, the breaker 23 inserted into the suction and breaking tube 22 breaks the hematoma sucked into the suction and breaking tube 22, in order to prevent blood from flowing into the suction and breaking port 26 to contaminate the lens of the neuroendoscope and affect the observation of the puncture process, a silica ring is embedded 1mm behind the convex lens head 25, the inserted neuroendoscope can be inserted into the silica ring to form a sealed cabin, keeping the lens clear and visible, facilitating clear observation of the tissue in front of the convex lens.

[0048] As shown in Figure 6 The puncture positioning principle of the present embodiment is shown, the puncture target point is a little lower than the center of the hematoma, the distance h1 of the puncture target point from the midline is measured on the CT, the distance h2 of the inner plate of the skull 2cm from the midline on the same side of the midline is calculated, and then h3=2h2-h1 is calculated, so that the size of h3 is obtained, the position of the adjusting sleeve 21 is determined, and the positions of the suction and breaking tube 22 and the breaker 23 are determined.

[0049] In the puncture process of the present embodiment, the positioning mechanism 1 is fixed to the appropriate position before puncture, then the breaker 23 in the hematoma suction device 2 is removed, the neuroendoscope is inserted into the suction and breaking tube 22, then the screw on the adjusting sleeve 21 is loosened, so that the suction and breaking tube 22 can move in the adjusting sleeve 21, then the suction and breaking tube 22 is slowly punctured, and the upper interface of the brain tissue changed into hematoma is observed, at this time the lens will turn white and red, the depth a0 of the suction and breaking tube 22 is recorded by using the scale on the suction and breaking tube 22, then the lower interface of the hematoma is observed, at this time the lens will turn red and white, the depth a00 of the suction and breaking tube 22 is recorded. The lower 1 / 3 of the hematoma is taken as the target point, that is, the puncture depth a=2 / 3(a00-a0)+a0=2 / 3a00-1 / 3a0. After reaching the puncture depth, the screw on the adjusting sleeve 21 is tightened to fix the position of the suction and breaking tube 22, then the neuroendoscope is withdrawn, the breaker 23 is inserted into the suction and breaking tube 22, the adjusting knob 24 on the breaker 23 is rotated while the blood clots are sucked out, the adjusting knob 24 has two different precision knobs, which can realize the breaking of the hematoma at different rates.
