Description

Technical Field

[0001] The present invention relates to the technical field of brain puncture, and particularly to a lateral ventricle drainage set with precise positioning. Background Technique

[0002] Lateral ventricle puncture and drainage is a surgery used to treat subarachnoid blockage, tuberculous bacterial meningitis accompanied by ventriculitis, and emergency reduction of intracranial pressure.

Visual puncture leads to inaccurate puncture direction and a large deviation in direction, resulting in surgical failure. Due to unbalanced pressure, the drainage effect of the drainage device is poor. There is no sediment removal device, so blood clots are likely to block the drainage hose. In addition, when too much liquid enters the drainage pot, unbalanced pressure will cause unsmooth drainage, affecting the treatment effect. Summary of the Invention

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. By setting an arc bracket, a bracket pin, a puncture bracket, a deflection pointer, a lateral displacement rod, and an angle scale, when aligning the puncture point, first draw a line and determine the puncture point on the patient's scalp, determine the median sagittal plane of the patient and the reference plane corresponding to the precise positioning puncture device, place the arc bracket on the patient's head, rotate the deflection pointer to an appropriate angle, and then adjust the drainage tube to an appropriate position so that the drainage tube is aligned with the puncture point, making the positioning during puncture more precise, increasing the puncture efficiency, ensuring the accuracy of the puncture direction and depth, and leading the drainage tube out from a position deviating from the scalp suture. After normally suturing the scalp, the liquid is not likely to flow out from the puncture point and the scalp suture, increasing the surgical success rate and reducing the hospital stay and hospitalization cost.

[0023] 2. By setting a catheter fixing slider, a folding upper cover of the catheter fixing slider, a drainage tube puncture catheter, a puncture steel needle, a drainage tube, and a laser head, when positioning the puncture position, a laser surface can be formed through the irradiation of the laser head, and the position of the laser surface can be adjusted to coincide with the head drawing line and the puncture point, and then puncture is performed. After puncture, open the catheter fixing slider and the folding upper cover of the catheter fixing slider, remove the precise positioning puncture device, and leave the drainage tube puncture catheter, the puncture steel needle, and the drainage tube, providing convenience for finding the puncture position and puncture operation.

[0024] 3. By setting a first drainage hose, a drainage pot, a precipitation cover, a second drainage hose, a small second flow control switch, a drainage rubber ball, a large flow control switch, a drainage bottle, a filter paper, and a pot cover, during drainage, the liquid enters the interior of the drainage pot, and the blood clots precipitate into the precipitation cover, without blocking the drainage channel. When the second drainage hose is blocked, by squeezing the drainage rubber ball, the blood clots are sucked in and then sent into the interior of the drainage bottle, making the drainage smoother and reducing the influence of blockage.

[0025] 4. By setting a drug injection and cleaning valve body, a steering valve core, a limit lock nut, and a valve cap, by rotating the steering valve core, the working state of the drug injection and cleaning valve is switched, facilitating drug injection, liquid injection and cleaning, and normal drainage, meeting the drainage operation and being more convenient to use.

[0026] In summary, through the combined use of the precise positioning puncture device and the drainage device, the puncture point can be precisely positioned during puncture, making the puncture more precise, with higher puncture efficiency. The puncture point deviates from the scalp suture, and when suturing the scalp, there is no obstruction from the drainage tube, and the liquid is not likely to flow out from the puncture point and the scalp suture. The later effect of puncture is better. The drainage device facilitates the precipitation and cleaning of blood clots, and the drainage is smoother. The use of the drug injection and cleaning valve facilitates liquid injection and liquid injection cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] A bracket base 2 is installed at the top of the main body arc bracket 1. A bracket pin 3 is installed at the top of the bracket base 2. A puncture bracket 4 is installed outside the bracket pin 3. A bracket handle 5 is installed at the top of the puncture bracket 4. A power supply 6 is embedded inside the bracket handle 5. A power supply lock nut 7 is installed at the top of the bracket handle 5. A power switch 8 is installed at the top of the power supply 6;

[0052] A deflection pointer 9 is rotatably installed in the middle of the puncture bracket 4. One end of the deflection pointer 9 is installed with a lateral displacement rod 10. An angle scale 11 is installed in the middle of the puncture bracket 4. A rotating rod is installed at the bottom end of the deflection pointer 9. The rotating rod is rotatably installed in the middle of the puncture bracket 4. The deflection pointer 9 points to the zero scale position at the center of the angle scale 11, which is convenient for the deflection pointer 9 to deflect at an appropriate angle to locate the puncture position. A catheter fixing slider 12 is slidably installed in the middle of the lateral displacement rod 10. A T-shaped chute is provided on the front end face of the lateral displacement rod 10. A T-shaped slider is installed at the rear end of the catheter fixing slider 12. The catheter fixing slider 12 is slidably connected to the T-shaped chute of the lateral displacement rod 10 through the T-shaped slider, enabling the catheter fixing slider 12 to slide to find the puncture position accurately. A catheter fixing slider folding upper cover 13 is installed at the front end of the catheter fixing slider 12. A drainage tube puncture catheter 14 is installed inside the catheter fixing slider 12. Both the catheter fixing slider 12 and the catheter fixing slider folding upper cover 13 are semi-cylindrical tubular structures. One side of the catheter fixing slider 12 is connected to one side of the catheter fixing slider folding upper cover 13 through a hinge. A pull rod is installed on the outside of the catheter fixing slider folding upper cover 13, which is convenient for the fixation and removal of the drainage tube puncture catheter 14. A puncture steel needle 15 is installed inside the drainage tube puncture catheter 14. A drainage tube 16 is installed inside the drainage tube puncture catheter 14. Laser heads 17 are installed on both sides of the puncture bracket 4;

[0053] One end of the drainage tube 16 is connected to a scalp puncture needle 33. Clamping grooves are provided on the outer sides of both ends of the scalp puncture needle 33. The needle position of the scalp puncture needle 33 is an arc structure. A thread is provided on the inner side of one end of the scalp puncture needle 33, which is convenient for clamping and installing the scalp puncture needle 33. The scalp puncture needle 33 is clamped by a clamping forceps 34.

[0054] Embodiment 2:

[0055] The steps of precise positioning and puncture are as follows:

[0056] The first step: Determine the puncture point;

[0057] As Figure 3-4 shown, according to the head CT, determine the human horizontal plane, sagittal plane and coronal plane, draw lines on the head body surface, determine the position of the punctured ventricle, mark the puncture point, puncture direction and puncture depth, or use 3D-Slicer software to determine the puncture point, puncture direction and puncture depth. Drill a hole with a bone drill at the preset puncture point, drill through the scalp, skull and dura mater, and the drilling direction is parallel to the puncture direction.

[0058] The second step: Place the precise positioning and puncture device;

[0059] As Figure 5As shown in the figure, the mid-plane of the main body arc bracket 1 of the precise positioning puncture device is determined as the first reference plane, and then the second reference plane perpendicular to the first reference plane is determined. The main body arc bracket 1 at the lower part of the precise positioning puncture device is placed on the median sagittal plane of the head. The first reference plane of the precise positioning puncture device coincides with the sagittal plane of the human body. Move the bracket base 2 and the puncture bracket 4 back and forth along the main body arc bracket 1, and stop moving after determining the optimal position.

[0060] Step 3: Align the puncture body surface line;

[0061] As Figure 6-7 shown in the figure, turn on the light sources of the two infrared laser heads 17 on the puncture bracket 4, and rotate the puncture bracket 4 back and forth around the bracket pin 3 so that the horizontal laser plane emitted coincides exactly with the line of the coronal plane to be pre-punctured on the body surface. Stop the back-and-forth rotation after determining the optimal position.

[0062] Step 4: Adjust the puncture angle;

[0063] As Figure 8 shown in the figure, adjust the deflection pointer 9 to rotate left and right according to the pre-determined puncture angle value, and make the puncture angle of the drainage tube 16 of this device reach the pre-determined value according to the angle of the angle scale 11. Stop the left-and-right rotation after determining the optimal angle.

[0064] Step 5: Align the puncture point;

[0065] As Figure 9 shown in the figure, put the drainage tube 16 with the puncture steel needle 15 into the drainage tube puncture catheter 14 and put it into the catheter fixing sliding seat 12, close the folding upper cover 13 of the catheter fixing sliding seat to seal it, move the position of the catheter fixing sliding seat 12 left and right so that the center of the bottom end of the drainage tube 16 is directly opposite to the center of the puncture point, stop moving the catheter fixing sliding seat 12 left and right, and lock the T-shaped slider on the rear end face of the catheter fixing sliding seat 12.

[0066] Step 6: Puncture the drainage tube 16;

[0067] As Figure 10 shown in the figure, move the puncture steel needle 15 downward to drive the head end of the drainage tube 16 to fall into the already punctured hole. Keep the drainage tube puncture catheter 14 stationary, open the folding upper cover 13 of the catheter fixing sliding seat, quickly remove the precise positioning puncture device, leaving only the drainage tube 16, the puncture steel needle 15 and the drainage tube puncture catheter 14. Keep the angle of the drainage tube puncture catheter 14 after positioning, press down the puncture steel needle 15, send the drainage tube 16 to the preset depth in the brain, and remove the puncture steel needle 15, leaving only the drainage tube 16.

[0068] Step 7: Pierce the scalp external drainage tube 16;

[0069] As Figure 2 、 11As shown in the figure, the push tube of the drainage tube 16 after puncture is threadedly connected to the rear end of the scalp puncture needle 33. The rear groove of the scalp puncture needle 33 is clamped by the clamping forceps 34 to pierce the scalp beside the incision. Then, the front groove at the rear of the scalp puncture needle 33 is clamped by the clamping forceps 34 to bring out the scalp puncture needle 33 and the drainage tube 16 together, and the drainage tube 16 is fixed. Then, the scalp incision is sutured, and the drainage tube 16 is externally connected to a drainage device.

[0070] The drainage tube 16 is led out from a position deviating from the scalp suture line, and the scalp is sutured normally. It is not easy for the liquid to flow out from the puncture point and the scalp suture. Since the drainage tube 16 is thin and soft, it can be directly withdrawn after the operation without affecting the healing speed of the scalp suture wound.

[0071] Step 8: Externally connect a drainage device.

[0072] Example 3:

[0073] As Figure 12 shown in the figure, the drainage device includes a medicine injection and cleaning valve 18, a first drainage hose 19, a drainage pot 21, a second drainage hose 24, a second small flow control switch 25, a drainage rubber ball 26, a large flow control switch 28, a drainage bottle 29, a filter bracket 30, a filter paper 31 and a pot cover 32;

[0074] One end of the drainage tube 16 is threadedly connected to a drug injection and cleaning valve 18. One end of the drug injection and cleaning valve 18 is connected to a first drainage hose 19. A first flow control switch 20 is sleeved outside the first drainage hose 19. The top end of the first drainage hose 19 is connected to a drainage pot 21. The bottom end of the drainage pot 21 is threadedly connected to a precipitation cover 22. A blood clot discharge port is installed at the bottom end of the drainage pot 21. The precipitation cover 22 is threadedly connected to the outside of the blood clot discharge port, facilitating blood clot precipitation and blood clot discharge. A hanging strap 23 is connected to the top end of the drainage pot 21. A second drainage hose 24 is connected to the bottom end of the drainage pot 21. Two drainage connection pipes are installed at the bottom of the drainage pot 21. The first drainage hose 19 and the second drainage hose 24 are respectively installed at the bottom ends of the two drainage connection pipes. The top end of the drainage connection pipe connected to the first drainage hose 19 is placed at the top position of the drainage pot 21. The top end of the drainage connection pipe connected to the second drainage hose 24 is placed at the bottom position of the drainage pot 21, facilitating liquid drainage and blood clot precipitation and avoiding pipeline blockage. A second flow control switch 25 is sleeved outside the second drainage hose 24. The bottom of the second drainage hose 24 is connected to a drainage rubber ball 26. The bottom of the drainage rubber ball 26 is connected to a thick drainage hose 27. A large flow control switch 28 is sleeved outside the thick drainage hose 27. The bottom end of the thick drainage hose 27 is connected to a drainage bottle 29. Hooks are symmetrically installed at the top of the back end of the drainage bottle 29. The top of the hook is of an arc structure, facilitating the fixation of the drainage bottle 29. Filter brackets 30 are installed at the tops of both the drainage pot 21 and the drainage bottle 29. A filter paper 31 is embedded in the middle of the filter bracket 30. A pot cover 32 is installed at the top of the filter bracket 30. Liquid discharge ports are installed at the top ends of both the drainage pot 21 and the drainage bottle 29. The filter bracket 30 is installed inside the liquid discharge port. A number of exhaust holes are opened at the top of the pot cover 32, facilitating the installation of the filter bracket 30 and the pot cover 32 and ensuring pressure balance.

[0075] As Figure 13 shown, the drug injection and cleaning valve 18 includes a drug injection and cleaning valve body 1801, a steering valve core 1802, a limit lock nut 1803, and a valve cap 1804;

[0076] The steering valve core 1802 is rotatably embedded on one side of the drug injection and cleaning valve body 1801. A limit lock nut 1803 is installed at the position corresponding to the steering valve core 1802 on one side of the drug injection and cleaning valve body 1801. A valve cap 1804 is installed at one end of the steering valve core 1802

[0077] Example 4:

[0078] As Figure 12-14 shown, connect the drainage tube 16 to the drainage device in sequence and start the following drainage process:

[0079] 1. Adjust the first flow control switch 20 on the left to control the flow rate of the liquid in the brain to the drainage pot 21;

[0080] 2. The drained liquid enters the first drainage hose 19 from the drainage tube 16, and finally enters the drainage pot 21, where it precipitates. Opening the sediment cover 22 can discharge the sediment, avoiding clogging of the second drainage hose 24, reducing the replacement of the drainage pot 21, and lowering the cost;

[0081] 3. The hanging strap 23 on the drainage pot 21 can hang the drainage pot 21 on the bracket;

[0082] 4. The additional filter bracket 30, filter paper 31 and pot lid 32 on the drainage pot 21 can prevent the generation of negative pressure phenomenon and ensure pressure balance on the premise of ensuring gas cleanliness;

[0083] 5. The top of the drainage connection tube connected to the first drainage hose 19 is located at the top of the drainage pot 21, so that the liquid flows into the interior of the drainage pot 21. When there is more liquid in the upper layer, it can be discharged from the liquid discharge port at the bottom of the drainage pot 21. The sediment cover 22 at the bottom of the drainage pot 21 is conducive to the precipitation of blood clots. The top of the drainage connection tube connected to the second drainage hose 24 is located at the bottom of the drainage pot 21, at a certain height from the bottom end of the drainage pot 21. The blood clots generated during drainage can be deposited in the drainage pot 21 and are not easily blocked by the second drainage hose 24;

[0084] 6. The drainage rubber ball 26 and the second small flow control switch 25 and the large flow control switch 28 on both sides thereof can clear the blood clots in the second drainage hose 24 and keep the drainage smooth;

[0085] When the second drainage hose 24 is blocked by blood clot precipitation, close the right second small flow control switch 25, keep the large flow control switch 28 in the open state, squeeze the drainage rubber ball 26, close the large flow control switch 28, open the right second small flow control switch 25, and then release the drainage rubber ball 26 to make the blood clot precipitation flow into the drainage rubber ball 26. Then close the second small flow control switch 25 and open the large flow control switch 28 to discharge the blood clot precipitation through the thick drainage hose 27 into the drainage bottle 29;

[0086] 7. The additional filter bracket 30, filter paper 31 and pot lid 32 on the drainage bottle 29 can prevent the generation of negative pressure phenomenon and ensure pressure balance on the premise of ensuring gas cleanliness;

[0087] 8. A hook is installed at the rear end of the drainage bottle 29, and the drainage bottle 29 is hung on the bedside railing through the hook.

[0088] Such as Figure 15 shown, the three working states of the drug injection and cleaning valve 18 in the drainage device:

[0089] Drug injection state: Rotate the steering valve core 1802 so that its port faces the drainage tube 16, open the valve cap 1804, and use a syringe to inject drugs into the brain to meet the daily drug injection needs;

[0090] Liquid injection and cleaning state: Rotate the steering valve core 1802 so that its port faces the first drainage hose 19, open the valve cap 1804, and use a syringe to inject liquid into the left first drainage hose 19 to clean the blocked first drainage hose 19;

[0091] Normal drainage state: Pull the steering valve core 1802 backward to make the internal channel of the medicine injection and cleaning valve body 1801 conduct, cover the valve cap 1804 to make the drainage channel unobstructed to meet normal drainage.

[0092] Finally, it should be noted that the above are only preferred examples of the present invention and are not used to limit the present invention. Although the present invention 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 perform equivalent replacements for some of the technical features.
