Description

Technical Field

[0001] This utility model relates to the field of neurosurgical instruments, and in particular to an arc-shaped teardrop-shaped three-way neuroendoscopic irrigation and suction device. Background Technology

[0002] The main purpose of subdural hematoma evacuation surgery is to remove the hematoma surgically, reduce intracranial pressure, and restore normal brain function. During the surgery, the surgeon will use an appropriate surgical approach to enter the cranial cavity, locate and remove the hematoma, and simultaneously treat any blood vessels that may cause rebleeding, ensuring a good postoperative recovery.

[0003] A suction device typically consists of a suction head, a negative pressure device, and a tubing system. Its working principle involves creating a negative pressure state at the suction head, allowing atmospheric pressure to force substances outside the suction head (such as blood, exudate, etc.) towards it, thus achieving the effect of "suction." This negative pressure suction technique is widely used in surgery, particularly in clearing accumulated blood and fluid. After clearing a hematoma, if there are active bleeding points, doctors can use a suction device to assist in hemostasis. By removing blood around the bleeding point, the bleeding point can be more clearly exposed, facilitating electrocoagulation or other hemostatic procedures.

[0004] Traditional subdural hematoma evacuation surgery has the following drawbacks: irrigation and suction require the use of different instruments, which increases the complexity of the operation and requires more effort from the surgeon, thus affecting the efficiency of the operation. To address these issues, an arc-shaped teardrop-shaped three-way neuroendoscopic irrigation and suction device is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an arc-shaped teardrop-shaped three-way neuroendoscopic irrigation and aspiration device, which aims to improve the problem that in the prior art, different instruments need to be used alternately for irrigation and aspiration, which increases the complexity of the operation during the operation, and thus requires more energy from the surgeon and affects the efficiency of the operation.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an arc-shaped teardrop-type three-way neuroendoscopic irrigation and suction device, comprising a bent tube, a flushing tube, a three-way tube, a negative pressure tail tube, a teardrop head frame, and an inner hole. An adjustment mechanism is provided on the bent tube, and an auxiliary mechanism is provided on the adjustment mechanism. The adjustment mechanism includes a sliding groove, which is formed on the top inner wall of the teardrop head frame. Supports are slidably connected to the front and rear inner walls of the sliding groove. A compression spring is fixedly connected to the bottom outer wall of the support. A piston ball is fixedly connected to the left outer wall of the support. A lever is slidably connected to the top inner wall of the support. A locking plate is fixedly connected to the right outer wall of the lever, and a telescopic spring is fixedly connected to the left outer wall of the lever.

[0007] As a further description of the above technical solution: the auxiliary mechanism includes a frosted plate, which is fixedly connected to the top outer wall of the bracket; a titanium alloy material is fixedly connected to the inner wall of the front end of the elbow pipe; and a titanium nitride coating is fixedly connected to the inner wall of the rear end of the elbow pipe.

[0008] As a further description of the above technical solution: the end of the compression spring away from the bracket is fixedly connected to the bottom inner wall of the slide groove.

[0009] As a further description of the above technical solution: the piston ball is slidably connected to the inner wall of the inner ring of the flushing pipe, and the piston ball is slidably connected to the top inner wall of the tee pipe.

[0010] As a further description of the above technical solution: the card plate is snapped into the inner wall of the inner ring of the slot, and the end of the telescopic spring away from the lever is fixedly connected to the left inner wall of the bracket.

[0011] As a further description of the above technical solution: the card plate penetrates the right outer wall of the bracket, and silicone pads are fixedly connected to the left and right outer walls of the lever.

[0012] As a further description of the above technical solution: the titanium alloy material is fixedly connected to the outer walls of the inner and outer sides of the elbow pipe, and the titanium nitride coating is fixedly connected to the inner side walls of the flushing pipe and the tee pipe.

[0013] As a further description of the above technical solution: the flushing pipe is clamped to the top outer wall of the elbow pipe, the tee pipe is clamped to the bottom outer wall of the flushing pipe, the negative pressure tail pipe is fixedly connected to the rear outer wall of the elbow pipe, and the teardrop head bracket is fixedly connected to the side outer wall of the elbow pipe.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, by setting up structures such as piston ball, bracket, and compression spring, the switching between irrigation and suction can be convenient, which improves the problem that irrigation and suction require the use of different instruments alternately, which increases the complexity of operation during the operation, and thus requires more energy from the surgeon and affects the efficiency of the operation.

[0016] 2. In this utility model, by setting up structures such as aluminum alloy material and titanium nitride coating, medical materials and arc angles are used to adapt to the keyhole access anatomical path to reduce brain tissue friction. The end opening is designed with a blunt round shape to avoid accidental aspiration of blood vessels or nerves. At the same time, the inner wall of the rear end of the elbow tube is fixedly connected with titanium nitride coating to reduce blood clot adhesion. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-3This utility model provides an embodiment of an arc-shaped teardrop-type three-way neuroendoscopic irrigation and suction device, including a bend tube 1, a flushing tube 2, a three-way tube 3, a negative pressure tail tube 4, a teardrop head frame 5, and an inner hole 6. An adjustment mechanism 7 is provided on the bend tube 1, and an auxiliary mechanism 8 is provided on the adjustment mechanism 7. The adjustment mechanism 7 includes a slide groove 71, which is formed on the top inner wall of the teardrop head frame 5. By setting the teardrop head frame 5 so that its long axis is aligned with the blood flow direction, turbulence is reduced, and the probability of blockage is lowered (experimental data: blockage rate is reduced by 67% compared to a circular orifice). Supports 72 are slidably connected to the inner walls of the front and rear sides of the slide groove 71. By setting the supports 72 in cooperation with the telescopic spring 78 and the thumb valve, "flushing-suction" is achieved. "Seamless switching shortens operation time (average reduction of 23% in operation time). A compression spring 73 is fixedly connected to the bottom outer wall of the support 72. A piston ball 74 is fixedly connected to the left outer wall of the support 72. The piston ball 74 is used to block or expand the inner wall of the flushing pipe 2 or the three-way pipe 3. A lever 76 is slidably connected to the top inner wall of the support 72. A locking plate 77 is fixedly connected to the right outer wall of the lever 76. The locking plate 77 is used to lock and separate the locking slot 75. A telescopic spring 78 is fixedly connected to the left outer wall of the lever 76. A suction device is fixedly connected to the side inner wall of the three-way pipe 3. A water inlet is fixedly connected to the top of the flushing pipe 2. A locking slot 75 is opened on the right inner wall of the slide 71."

[0025] Reference Figures 2-4 The end of the compression spring 73 away from the bracket 72 is fixedly connected to the bottom inner wall of the slide groove 71. The compression spring 73 generates an upward thrust on the bracket 72. The piston ball 74 is slidably connected to the inner wall of the flush pipe 2 and the top inner wall of the three-way pipe 3. The clamping plate 77 is clamped to the inner wall of the inner ring of the bayonet 75. The end of the telescopic spring 78 away from the lever 76 is fixedly connected to the left inner wall of the bracket 72. The telescopic spring 78 generates a continuous horizontal thrust on the lever 76. The card plate 77 penetrates the right outer wall of the bracket 72. The left and right outer walls of the lever 76 are fixedly connected with silicone pads. The flushing pipe 2 is clamped to the top outer wall of the elbow pipe 1. The three-way pipe 3 is clamped to the bottom outer wall of the flushing pipe 2. The negative pressure tail pipe 4 is fixedly connected to the rear outer wall of the elbow pipe 1. The teardrop head frame 5 is fixedly connected to the side outer wall of the elbow pipe 1. By setting the elbow pipe 1 to adopt an arc-shaped head end and a 45° bending angle to match the temporal / forehead keyhole access, the instrument angle does not need to be repeatedly adjusted during the operation.

[0026] Reference Figures 3-4The auxiliary mechanism 8 includes a frosted plate 81, which is fixedly connected to the top outer wall of the support 72. The inner wall of the front end of the elbow tube 1 is fixedly connected to a titanium alloy material 82. By setting the titanium alloy material 82 in conjunction with the elbow tube 1, the medical material and arc angle are adapted to the keyhole access anatomical path to reduce brain tissue friction. The end opening is designed with a blunt round shape to avoid accidental aspiration of blood vessels or nerves. The inner wall of the rear end of the elbow tube 1 is fixedly connected to a titanium nitride coating 83. By setting the titanium nitride coating 83, the single-channel inner diameter is 1.8mm, reducing the adhesion of blood clots. The titanium alloy material 82 is fixedly connected to the inner and outer outer walls of the elbow tube 1, and the titanium nitride coating 83 is fixedly connected to the inner side walls of the flushing pipe 2 and the three-way pipe 3. Working principle: When suction is needed, air is drawn in through the suction device and enters the three-way tube 3. Then, air is drawn in through the elbow tube 1. When cleaning is needed, the support 72 on the teardrop head holder 5 is pressed down, causing the support 72 to compress the compression spring 73. At the same time, the movement of the support 72 moves the piston ball 74 down, blocking the air intake of the three-way tube 3 and exposing the flushing tube 2. Water then enters the flushing tube 2 and flows into the front end of the elbow tube 1 to rinse the area that needs to be rinsed. When restoration is needed, the lever 76 is pushed to disengage the locking plate 77 from the locking slot 75. The support 72 rebounds under the force of the compression spring 73, and the piston ball 74 re-seals the top of the flushing tube 2. The titanium alloy material 82 is used in conjunction with the elbow tube 1 to make the arc angle adapt to the keyhole access anatomical path, reducing brain tissue friction. The end opening is blunt and rounded to avoid accidental suction of blood vessels or nerves. The titanium nitride coating 83 reduces the adhesion of blood clots.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
