Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and more specifically to a cerebral hemorrhage endoscope with an adjustable and fixed suction structure. Background Art

[0002] Hypertensive intracerebral hemorrhage (HICH) is a common and frequently occurring disease in neurosurgery, with high disability and mortality rates. HICH accounts for 43.0% to 51.0% of cerebrovascular diseases, mainly in people over 55 years old, but has a trend of younger age in recent years. HICH progresses rapidly, and if the hematoma volume exceeds 20.0 mL, the disability rate can reach 30.0%. The surgical treatment of HICH, namely the removal of intracerebral hematoma, can increase the chance of survival, thereby improving the prognosis and the quality of life of patients.

[0003] At present, there are three main surgical treatments for cerebral hemorrhage: the first is craniotomy to remove the intracranial hematoma. This operation takes a long time, causes a lot of blood loss and trauma, and causes severe postoperative edema, which affects the patient's prognosis. The second is small bone window craniotomy to remove the hematoma. This operation takes a short time, has a small incision, and causes little brain damage. It can completely remove the hematoma under direct vision, find the responsible blood vessels, and stop bleeding in time, fully decompress, and is easy to operate. The third is stereotactic-assisted intracranial hematoma cavity drilling and drainage. This minimally invasive surgery uses a punching method, which causes less trauma, but it cannot fully decompress the blood vessels in time, and cannot stop bleeding reliably under direct vision.

[0004] Among them, small bone window craniotomy hematoma removal can be completed with the assistance of a microscope or neuroendoscope, but due to the small cortical incision range under the small bone window, the hematoma cannot be clearly displayed through the microscope. If difficult-to-stop bleeding occurs during the operation, the cortical wound must be enlarged to ensure a satisfactory surgical field. The use of a neuroendoscope can provide high-intensity lighting, close observation, and clear identification of the hematoma and adjacent tissues for accurate treatment. It can also visually observe the range of the hematoma to ensure reliable hemostasis. A Chinese patent document with application number 202221676938.1 discloses an endoscope sleeve device with a suction function, and the method of using the sleeve device is as follows: insert the front end of the sleeve carrying a core rod and a suction tube into the hematoma cavity, and then pull the core rod out of the sleeve from the rear end through a handle rod, forming an endoscope channel inside the sleeve, and an endoscope and bipolar electrocoagulation can be entered into the endoscope channel to perform hematoma removal and hemostasis operations. When stopping bleeding, push the suction tube to the front end until the extended section extends out of the end of the sleeve, and use the suction hole in combination with a negative pressure suction device to suck blood and water, so as to provide a surgical field for bipolar electrocoagulation hemostasis.

[0005] In existing neuroendoscopic hematoma removal surgery, a suitable cannula is usually placed in the hematoma cavity, and the hematoma is attracted and hemostasis is performed in the internal space of the cannula. During the operation, the endoscope and the suction device are placed into the hematoma cavity through the cannula to extract the hematoma. If there is clear active bleeding, a bipolar coagulation device needs to be inserted for electrocoagulation hemostasis. When stopping active bleeding, the assistant can hold the endoscope to cooperate, and the operator can perform "two-handed" hemostasis under direct vision of the endoscope. The assistant holds the endoscope to show the active bleeding blood vessel stump to the operator, and the operator holds the suction device in the left hand and the bipolar coagulation device in the right hand to perform "two-handed" hemostasis.

[0006] During the operation, there are disadvantages of the three instruments, the aspirator, the endoscope, and the bipolar electrocoagulation, interfering with each other in the working channel, as well as the problem of the two people's operation being out of sync. Summary of the invention

[0007] In view of the disadvantages of mutual interference among the three instruments, namely, the aspirator, the endoscope and the bipolar electrocoagulation, in the working channel during the existing small bone window craniotomy and hematoma removal surgery, as well as the problem of unsynchronized operation between two people, this scheme provides a brain hemorrhage endoscope with an adjustable and fixed suction structure.

[0010] The insertion part is a rigid structure, and its front end is a head end seat. A plurality of through holes are provided on the head end seat, and the through holes are used to connect the instrument channel and the blood suction cannula channel;

[0012] The instrument channel is connected to the instrument insertion port, the electrocoagulator is slidably placed in the instrument channel and the head end of the electrocoagulator extends out of the head end seat;

[0013] The blood suction cannula channel is connected to the blood suction cannula channel opening, and a blood suction cannula insertion joint is installed at the blood suction cannula channel opening. A locking mechanism is provided on the blood suction cannula insertion joint. The flexible structure of the blood suction cannula adjusts the length of the blood suction cannula head end extending out of the head end seat through the locking mechanism, and is locked in the blood suction cannula channel through the locking mechanism.

[0014] Furthermore, the locking mechanism comprises a blood suction channel interface and a locking wheel, one end of the blood suction cannula away from the head end seat extends out of the blood suction channel interface, and the locking wheel is sleeved on the blood suction channel interface and locks the blood suction cannula by rotation.

[0015] Furthermore, the blood-sucking channel interface is an elliptical cylinder structure, the cylinder is provided with a slot extending from the front end surface along the length direction of the cylinder, a locking hole is provided at the center position of the locking wheel, the elliptical cylinder structure is inserted into the locking hole, and the locking wheel is rotated to squeeze the slot to form a locking fit.

[0016] Furthermore, a step is provided on the circumferential surface of the blood-sucking channel interface, and a convex edge is provided at a side opening of the locking hole close to the blood-sucking channel interface, and the convex edge abuts against the step.

[0017] Furthermore, the locking wheel is provided with a triangular push block extending radially outward.

[0018] Furthermore, a limiting block is arranged on one end surface of the locking wheel close to the blood sucking channel interface, and a rotation path for the limiting block to move is opened along the circumferential direction of the blood sucking channel interface.

[0019] Furthermore, it comprises a connecting portion, and the connecting portion is connected to the bottom end of the operating handle of the operating portion through a cable.

[0020] Furthermore, the through hole on the head end seat is also connected to a camera channel, a light source channel and a flushing / overflow channel.

[0021] Furthermore, the instrument insertion port is arranged above the blood suction cannula channel port and the flushing / overflow channel port, and is coaxially arranged with the instrument channel.

[0022] Furthermore, the caliber of the blood suction cannula channel opening is larger than the calibers of the instrument insertion opening and the flushing / overflow channel opening, and the blood suction cannula channel opening is arranged above the instrument insertion opening and the flushing / overflow channel opening.

[0023] Compared with the prior art, the technical solution provided by the utility model has the following beneficial effects:

[0024] (1) The brain hemorrhage endoscope of the present invention adds channels for electrocoagulation and blood suction components, and "combines" the endoscope, the suction device, and the electrocoagulator into one. The blood suction component can be fixedly connected to the endoscope body. The operator holds the brain hemorrhage endoscope of this solution in the left hand, and can simultaneously complete the suction and lighting tasks, freeing up the right hand to use bipolar electrocoagulation to electrocoagulate the active bleeding blood vessel ends in the corresponding working channel of the endoscope. The brain hemorrhage endoscope of this solution can be operated by a single operator, which not only avoids the disadvantages of the three instruments, the suction device, the endoscope, and the bipolar electrocoagulation, interfering with each other in the working channel, but also avoids the problem of asynchronous operation of two people. It combines the advantages of two-handed operation of microsurgeons and good lighting and clear magnification of neuroendoscopes.

[0025] (2) The blood-sucking cannula channel of the midbrain hemorrhage scope of the utility model cooperates with the insertion joint to realize the fixed connection between the blood-sucking cannula and the scope body, and the extension distance can be manually adjusted, thereby avoiding the problem of the lens being blocked by blood and mucus. In addition, in order to facilitate the removal of lateral hematoma, the blood-sucking cannula is designed as a flexible structure that can be bent at a certain angle, that is, the blood-sucking cannula can be manually bent to shape, and the bending angle can also be adjusted by structures such as snake bones.

[0026] (3) Since there are different requirements for the inner diameter of the blood suction cannula channel in actual use scenarios, the utility model provides a solution for expanding the inner diameter of the blood suction cannula channel to facilitate the suction of larger hematomas.

[0046] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the drawings and embodiments.

[0047] The structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no substantial technical significance. Any modification of the structure, change of the proportion relationship or adjustment of the size, without affecting the effect and purpose that can be achieved by the utility model, should still fall within the scope of the technical content disclosed by the utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and so on quoted in this specification are only for the convenience of description, and are not used to limit the scope of implementation. The change or adjustment of their relative relationship should also be regarded as the scope of implementation of the utility model without substantial change of the technical content.

[0048] like Figure 1As shown, the intracerebral hemorrhage endoscope with an adjustable and fixed suction structure of this embodiment includes an insertion portion 100, an operating portion 200 and a connecting portion 300. The insertion portion 100 is a rigid structure and cannot be bent. The connecting portion 300 is connected to the bottom end of the operating handle 220 of the operating portion 200 through a cable 230.

[0049] like Figure 2-1 and 2-2 As shown, the front end of the insertion part 100 is a head end seat 101, and a plurality of through holes are provided on the head end seat 101, three of which are respectively connected to a camera channel 110 and two groups of light source channels 120, for installing a camera and two groups of light sources, which are preferably optical fiber or LED lighting.

[0050] The other three through holes are used to connect the instrument channel 130 , the blood suction cannula channel 140 , and the flushing / overflow channel 150 , respectively.

[0051] Furthermore, the rear of the head end seat 101 can be connected to the main sleeve of the insertion part, and the outer sleeve of the insertion part wraps the rear end of the head end seat 101 and the main sleeve of the insertion part. The outer sleeve of the insertion part plays a role in stabilizing the connection and making the insertion part 200 flat and without edges to avoid damage to brain tissue.

[0052] The operating part is composed of a channel opening 210 and an operating handle 220. The operating handle 220 includes a handle lower shell 221 and a handle top cover 222. The channel opening 210 includes an instrument insertion opening 211, a blood suction cannula channel opening 212 and a flushing / overflow channel opening.

[0053] like Figure 3-1 and 3-2 As shown, the instrument insertion port 211 is arranged at the upper end, which is convenient for inserting instruments such as electrocoagulators. The flushing / overflow channel port and the blood suction cannula channel port 212 are arranged below the instrument insertion port 211. The port of the flushing / overflow channel port is a Luer connector, and the port of the blood suction cannula channel port 212 is a blood suction cannula insertion connector 213. The instrument insertion port 211 is coaxially arranged with the instrument channel 130 to ensure that the instrument channel 130 is straight and not bent.

[0054] Since the operator needs to control the length of the electrocoagulator extending from the end of the cerebral hemorrhage lens at any time, the electrocoagulator needs to be able to move freely in the channel. In this embodiment, the instrument channel 130 is connected to the instrument insertion port 211, and the electrocoagulator 250 is slidably placed in the instrument channel 130 and the head end of the electrocoagulator 250 extends out of the head end seat 101.

[0055] In order to allow the operator to complete the suction work simultaneously while holding the endoscope with one hand, the blood suction cannula needs to be fixedly connected to the endoscope.

[0056] In this regard, the blood suction cannula channel 140 of the present embodiment is connected to the blood suction cannula channel opening 212, and a blood suction cannula insertion joint 213 is installed at the blood suction cannula channel opening 212. A locking mechanism is provided on the blood suction cannula insertion joint 213. The blood suction cannula 240 adjusts the length of the head end of the blood suction cannula 240 extending out of the head end seat 101 through the locking mechanism, and is locked in the blood suction cannula channel 140 through the locking mechanism.

[0057] During use, the operator inserts the blood suction cannula into the intracerebral hemorrhage endoscope and, under the guidance of the image of the intracerebral hemorrhage endoscope, extends the tip of the blood suction cannula to an appropriate distance beyond the lens end of the intracerebral hemorrhage end, and then locks the blood suction cannula through the locking mechanism on the blood suction cannula insertion connector. During the operation, the operator can adjust the length of the blood suction cannula extending out of the lens end of the intracerebral hemorrhage end at any time through the locking mechanism.

[0058] The blood suction function structure of the cerebral hemorrhage endoscope of this embodiment is different from that of the existing cerebral hemorrhage endoscope, which only adds a blood suction channel and uses a negative pressure device at the rear end of the channel. The blood suction channel of the endoscope is used to suck blood, that is, the end face of the blood suction channel is consistent with the end face of the lens. The disadvantage of this solution is that when sucking blood, the end of the cerebral hemorrhage lens needs to be close to or partially extended into the hematoma. The lens is easily blocked by coagulated blood or mucus and the surgical field cannot be seen clearly. Repeated flushing is required, which increases the difficulty of the operation.

[0059] In this embodiment, the blood suction cannula channel cooperates with the blood suction cannula insertion joint to achieve a fixed connection between the blood suction cannula and the scope body, and a manually adjustable extension distance function, thereby avoiding the problem of the lens being blocked by blood or mucus.

[0060] Furthermore, in order to facilitate the removal of lateral hematoma, the blood-sucking cannula adopts a flexible structure that can be bent at a certain angle, that is, the blood-sucking cannula can be shaped by manual bending, and the bending angle can also be adjusted by structures such as snake bones.

[0061] As an implementation method of the locking mechanism, Figure 4-1 to Figure 4-4 As shown, the locking mechanism includes a blood suction channel interface 214 and a locking wheel 215. The end of the blood suction cannula 240 away from the head end seat 101 extends out of the blood suction channel interface 214. The locking wheel 215 is sleeved on the blood suction channel interface 214 and locks the blood suction cannula 240 by rotation.

[0062] Specifically, the part where the blood-sucking channel interface 214 is connected to the locking wheel is an elliptical cylinder structure, and a slot 2141 is extended from the front end surface of the cylinder along the length direction of the cylinder. The locking wheel 215 has a locking hole 2151 at the center position that matches the elliptical cylinder of the blood-sucking channel interface.

[0063] When the blood-sucking cannula needs to be locked, the locking wheel is rotated 90 degrees, and the oval cylindrical groove of the blood-sucking channel interface is closed to press the blood-sucking cannula, thereby completing the locking; the locking wheel is rotated in the opposite direction to unlock.

[0064] Furthermore, in order to prevent the locking member from falling off, a step 2142 is provided on the circumferential direction of the blood sucking channel interface 214 , and a convex edge 2152 is provided at one side opening of the locking hole 2151 close to the blood sucking channel interface 214 , and the convex edge 2152 abuts against the step 2142 .

[0065] In order to facilitate the operator to push the locking wheel, Figure 6-3 to Figure 6-5 As shown, the shape of the locking wheel can be improved: the locking wheel 215 is radially extended outward to be provided with a triangular push block 216. Compared with the arc-shaped locking wheel, the locking wheel with a triangular push block is easier to push, which improves convenience and also helps to improve the comfort of the operator.

[0066] If the locking wheel rotates excessively during the operation, parts and instruments may be damaged. In this regard, the locking mechanism can be further improved: a limit block 217 is provided on one end face of the locking wheel 215 close to the blood suction channel interface 214, and a rotation path 218 for the limit block 217 to move is provided on the blood suction channel interface 214 along the circumferential direction.

[0067] By increasing the rotation path of the locking wheel, the rotation range of the locking wheel is limited, which can ensure that the locking wheel rotates to lock the blood suction cannula and prevent the locking wheel from rotating excessively to damage components and instruments.

[0068] Due to different requirements for the inner diameter of the blood suction cannula channel, it is sometimes necessary to enlarge the inner diameter of the channel to facilitate the suction of a larger hematoma. Therefore, the channel arrangement on the operating part needs to be changed, and the handle structure also needs to be changed accordingly.

[0069] As a channel arrangement, such as Figure 6-1 and Figure 6-2 As shown, the caliber of the blood suction cannula channel opening 212 is larger than the caliber of the instrument insertion opening 211 and the flushing / overflow channel opening, and the blood suction cannula channel opening 212 is arranged above the instrument insertion opening 211 and the flushing / overflow channel opening. Accordingly, this embodiment provides another operating handle structure, which includes a handle housing 223, a handle side cover 224, and a handle end cover 225.

[0070] The cerebral hemorrhage endoscope of this embodiment "combines" the endoscope, the aspirator, and the electrocoagulator into one by adding channels for electrocoagulation and blood suction components, and the blood suction component can be fixedly connected to the mirror body. The operator holds the cerebral hemorrhage endoscope of this solution in the left hand, and can simultaneously complete the suction and lighting tasks, freeing up the right hand to use bipolar electrocoagulation to electrocoagulate the active bleeding blood vessel ends in the corresponding working channel of the endoscope. The cerebral hemorrhage endoscope of this embodiment can be operated by the operator alone, which not only avoids the disadvantages of the three instruments, the aspirator, the endoscope, and the bipolar electrocoagulation, interfering with each other in the working channel, but also avoids the problem of asynchronous operation and coordination between two people, and combines the advantages of two-handed operation of the microsurgeon and good lighting and clear magnification of the neuroendoscope.

[0071] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
