[0001] The invention relates to the technical field of surgical instruments, and in particular to a flushing surgical device for neurosurgery. Background Art

[0002] In order to prevent blood and tissue fluid from affecting the surgeon's operation during neurosurgery, it is often necessary to use flushing water to ensure the cleaning of the surgical site at all times. In order to avoid contamination of the surgical environment, the flushing fluid is often absorbed after flushing. The current flushing surgical equipment needs to have two functions, namely, water absorption and flushing. Frequent switching is required during operation, which is inconvenient for doctors to use. In addition, the water absorption method is to generate pressure through a negative pressure pump for absorption. The pressure when absorbing the flushing fluid is relatively high, and there is a possibility of damage to tissue and skin. In addition, the contaminated cleaning fluid flows through the negative pressure pump again, which is very troublesome for subsequent cleaning and disinfection. Based on this, a flushing surgical device for neurosurgery is proposed. Summary of the invention

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "mounted / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] Example, see Figures 1 to 7 A neurosurgery flushing surgical device comprises a water supply device 1, a water purification device 2 and an operating member arranged on a storage member, wherein the water supply device 1 and the water purification device 2 are connected to the operating member through an external flushing pipe 3 and an internal reflux pipe 4 respectively;

[0033] A delivery pump is provided in the water supply device 1 for delivering the cleaning liquid, and there is no need to design a negative pressure pump, which can facilitate subsequent cleaning and disinfection.

[0034] Furthermore, the storage member includes a storage plate 12 connected by a support frame, a blocking notch 13 is provided on the storage plate 12, a fixed chuck 14 is fixedly connected to the outer wall of the operation control end 5, and the fixed chuck 14 is connected to a buffer cone 15 through a sleeve spring;

[0035] The internal reflux tube 4 is located inside the external flushing tube 3, and the outside of the external flushing tube 3 is connected to a counterweight block 16 through a locking assembly. By setting the counterweight block 16, it can automatically fall down and drive the operating part to automatically reset to the storage part during the doctor's operation, which is convenient for the doctor to use during the operation.

[0036] It is worth noting that a wire-releasing opening is provided at the top of the blocking notch 13 for installing the operating piece on the storage piece. The inner diameter of the blocking notch 13 is smaller than the diameter of the buffer conical disk 15. When in use, the setting of the counterweight 16 can ensure that there will be no pipeline confusion when the doctor pulls the operating piece for use. After use, the operating piece can be stored by the gravity of the counterweight 16, and the buffer conical disk 15 can absorb the impact force during falling to protect the operating piece.

[0037] The operating part includes an operating control end 5 and a pipeline assembly. The operating control end 5 is connected to a flushing head 6 through an extending and retracting support rod. Furthermore, the extending and retracting support rod includes a fixed support rod 17 connected to the operating control end 5. The side wall of the fixed support rod 17 is connected to the guide triangular support rod 7. The end of the fixed support rod 17 is fixedly connected to a connecting shaft 18.

[0038] The flushing head 6 is connected to the pipeline assembly through a locking adjustment piece. The pipeline assembly includes an inner core reflux chamber 8 and a flushing water supply chamber 9 opened in the operation control end 5. The inner core reflux chamber 8 and the flushing water supply chamber 9 are connected by a flushing outer tube 10. A blood water suction tube 11 is provided on the side wall of the flushing outer tube 10 located at the guide triangular support rod 7.

[0039] The inner core reflux chamber 8 is a channel for reflux liquid, and the flushing water supply chamber 9 is a channel for delivering cleaning liquid to the outside;

[0040] It is worth noting that the guiding triangular support rod 7 limits the angle of the flushing outer tube 10 to ensure the angle between the blood water suction tube 11 and the flushing outer tube 10;

[0041] In the present solution, the accumulated blood is discharged by causing the liquid to flow at a high speed in the flushing outer tube 10, thereby generating suction on the blood-water suction tube 11 connected to the flushing outer tube 10. Under the action of the suction, the cleaning liquid mixture used to clean the accumulated blood is sucked out and discharged outward through the flushing outer tube 10. The principle thereof can be referred to as the "Venturi effect". Compared with the existing negative pressure strong suction method, this method can effectively protect the intracranial tissue during surgery and avoid damage to the intracranial tissue due to the discharged liquid.

[0042] The locking adjustment member includes an inner support end seat 19 fixedly arranged on the connecting shaft 18, and a limiting disk 20 relatively arranged is rotatably arranged on the connecting shaft 18, and the two limiting disks 20 are commonly connected to a limiting arc cover 21;

[0043] A portion of the flushing outer tube 10 is located between the inner support end seat 19 and the limiting arc cover 21 , and a pressure-guaranteed sealing effect is achieved between the flushing outer tube 10 and the limiting arc cover 21 .

[0044] The limiting arc cover 21 is connected to the flushing head 6, and the flushing outer tube 10 is sleeved on the inner support end seat 19. The flushing outer tube 10 located at the inner support end seat 19 is provided with an adapter liquid outlet 22 that is compatible with the flushing head 6. A notch 23 is opened at the bottom of the inner support end seat 19, and a locking compression cross column 24 is fixedly connected to the limiting disk 20.

[0045] The outer flushing tube 10 is connected to the limiting arc cover 21 through the adapting liquid outlet 22, so as to deliver the high-pressure cleaning liquid to the flushing head 6, thereby achieving the cleaning of the surgical site.

[0046] It is worth noting that when the flushing work is performed, the adapting liquid outlet 22 and the limiting arc cover 21 are in the adapting position, and the limiting disk 20 rotates to move the locking compression cross column 24 to a position misaligned with the notch 23. At this time, the locking compression cross column 24 is in a position misaligned with the notch 23, and will work with the inner support end seat 19 to generate pressure on the flushing outer tube 10, and will close the channel for the flushing outer tube 10 to be transported outward, ensuring that the cleaning liquid is concentrated and high-pressure acts on the flushing head 6;

[0047] When it is necessary to absorb the accumulated blood and cleaning fluid without flushing, the limiting disk 20 can be rotated to drive the limiting arc cover 21 to rotate, so that the adapter liquid outlet 22 and the flushing head 6 on the limiting arc cover 21 are misaligned, and no water is discharged. During the rotation, the locking compression cross column 24 will be driven to rotate to the position of the notch 23. Due to the existence of the notch 23, the locking compression cross column 24 will not generate pressure on the flushing outer tube 10, so the flushing outer tube 10 will not be closed. The flushing outer tube 10 will transport high-pressure water back to the inner core reflux chamber 8. In this process, the high-pressure water flow will generate suction on the blood water suction tube 11, thereby realizing the absorption and transportation of sewage and tissue blood.

[0048] Similarly, when a small outflow of water and low-pressure absorption of flushing fluid are required, the rotation angle of the rotation limiting disk 20 can be controlled to achieve the above-mentioned effects and meet the needs during surgery.

[0049] The operation control end 5 is provided with a knob control component for controlling the rotation angle of the flushing head 6;

[0050] Furthermore, the knob control assembly includes a control rotating ring 25 rotatably arranged at the operating control end 5, a control gear disc 26 meshingly connected to the inner wall of the control rotating ring 25, the control gear disc 26 is fixedly connected to an extended worm 27, and the limiting disk 20 is connected to a worm gear 28 via a connecting ring extending outward through the side wall of the fixed support rod 17.

[0051] The extended worm 27 is connected to the operating member via a rotatably connected connecting block, and the meshing connection between the extended worm 27 and the worm wheel 28 is a prior art and will not be described in detail herein.

[0052] The extending and releasing support rod is provided with a guiding triangular support rod 7 for guiding the pipeline assembly to limit the position, and the side wall of the operation control end 5 is provided with a piezoresistive control unit for controlling the flow of the pipeline assembly;

[0053] Furthermore, the piezoresistive adjustment control unit includes a control slide groove opened at the operation control end 5, the control slide groove is slidably connected to a control slide rod 29, and the end of the control slide rod 29 is connected to a pressing roller 30 via a fixed rotating shaft.

[0054] The inner wall of the control slide groove is provided with a beveled tooth groove 31, and the control slide rod 29 is connected to the beveled rack 33 through a press-release button 32, and the beveled rack 33 is connected to the control slide rod 29 through a resistance spring, wherein the press-release button 32 is a control element commonly used in the field and will not be elaborated on here. When in use, the control slide rod 29 can be moved by pushing the press-release button 32 forward, thereby changing the control of the liquid flow by the pressure roller 30.

[0055] The present invention is used in surgery. When the surgical site needs to be flushed through the flushing head 6, the position of the limited arc cover 21 can be controlled by the knob control component, so that the limited arc cover 21 is connected to the position of the adapted liquid outlet 22. At this time, the locking compression cross column 24 closes the reflux position of the flushing outer tube 10, and the high-pressure flushing liquid flows out through the flushing head 6 to effectively flush the surgical site.

[0056] When it is necessary to absorb the flushing liquid and the accumulated blood, the limiting arc cover 21 is driven to rotate by rotating the limiting disk 20, so that the adapter liquid outlet 22 and the flushing head 6 on the limiting arc cover 21 are misaligned, and no water is discharged. During the rotation, the locking compression cross column 24 is driven to rotate to the position of the notch 23. Due to the existence of the notch 23, the locking compression cross column 24 will not generate pressure on the flushing outer tube 10, so the flushing outer tube 10 will not be closed. The flushing outer tube 10 will transport the high-pressure water back to the inner core reflux chamber 8. At this time, the blood and water suction tube 11 arranged on the flushing outer tube 10 will generate suction to effectively absorb the flushing liquid and the accumulated blood, and discharge them outward through the flushing outer tube 10 to achieve the transportation effect.

[0057] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
