Description

Technical Field

[0001] This utility model relates to medical equipment, and more particularly to a sterile microscope for neurosurgery. Background Technology

[0002] Microscopes are commonly used equipment in neurosurgery. To avoid contaminating the surgical area, a sterile microscope sleeve must be placed over the microscope arm during use. To prevent the expansion of air inside the sterile microscope sleeve from interfering with surgical procedures, most microscopes have a suction function. However, existing microscopes, microscope sleeves, and negative pressure suction devices are mostly used in a matching manner, requiring barcode verification on the microscope to activate the negative pressure suction device. This means the negative pressure suction device is not universally compatible, resulting in high operating costs and placing an economic burden on patients and hospitals. Furthermore, the negative pressure suction devices provided in operating rooms cannot be used for suction of the microscope sleeve. In addition, the microscope sleeve is not easy to install and lacks airtightness during air suction, and continuous suction is required, making it susceptible to interference from the operating noise of the negative pressure suction device during surgery. Finally, it has been found that the sterile microscope sleeve tends to close the vents prematurely during suction, causing suction failure. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a sterile microscope for neurosurgery, which improves the airtightness and the convenience of installing the sterile microscope cover. After the sterile microscope cover is tightly attached to the microscope arm, the negative pressure suction device can be turned off, reducing noise interference during surgery. Moreover, all parts except the sterile microscope cover can be reused, reducing the cost of consumables.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a sterile neurosurgical microscope, comprising a microscope and a sterile microscope sleeve, a negative pressure suction tube arranged along the arm of the microscope, the tail end of the negative pressure suction tube being sequentially connected to an extension tube, a three-way valve and a negative pressure suction device, and a suction hole being formed in the side wall of the negative pressure suction tube; the extension tube and the negative pressure suction device are respectively connected to the first and second ports of the three-way valve, and a rubber stopper is provided at the third port of the three-way valve; the sterile microscope sleeve is wrapped around the outside of the microscope arm and the negative pressure suction tube with tape, the tape being tied at both ends of the sterile microscope sleeve to achieve port closure, the front end of the negative pressure suction tube and the suction hole are both located inside the sterile microscope sleeve bound by the tape, and the tail end of the negative pressure suction tube protrudes from the sterile microscope sleeve.

[0005] As a preferred embodiment of this utility model, the negative pressure suction tube protrudes from the outer surface of the lens arm, the lower surface of the negative pressure suction tube is a plane that fits the upper surface of the lens arm, and the inner cross-section of the negative pressure suction tube is a flat ellipse.

[0006] As a preferred embodiment of this utility model, the upper surface of the negative pressure suction tube is an arc-shaped surface.

[0007] As a preferred embodiment of this utility model, the upper surface of the negative pressure suction tube includes two planes that meet at an obtuse angle.

[0008] As a preferred embodiment of this utility model, the negative pressure suction tube is embedded in the arm of the eyeglass, and the outer surface of the negative pressure suction tube is flush with the outer surface of the arm of the eyeglass.

[0009] As a preferred technical solution of this utility model, a spring corresponding to the suction hole is provided inside the negative pressure suction tube. The top of the spring is provided with a ball head. Under the natural length of the spring, the ball head partially extends beyond the outer port of the suction hole, and the ball head is smaller than the suction hole.

[0010] As a preferred technical solution of this utility model, the negative pressure suction tube is a rigid tube, and the tail end of the negative pressure suction tube is raised to separate it from the endoscope arm. The extension tube is a rubber tube, and both ends of the extension tube are connected to the negative pressure suction tube and the three-way valve respectively through threaded pipe joints.

[0011] As a preferred technical solution of this utility model, the negative pressure suction device is a general-purpose device configured in the operating room, which can quickly connect to the negative pressure suction tube.

[0012] The beneficial effects of adopting the above technical solution are as follows: This utility model improves the airtightness by improving the shape of the negative pressure suction tube. The sterile microscope sleeve and the negative pressure suction tube, extension tube, three-way valve and negative pressure suction device for air extraction can be quickly installed through the hook inside the threaded tube connector, which improves the convenience of microscope preparation before surgery. Due to the good airtightness and the rubber plug of the third interface of the three-way valve, the negative pressure suction device can be closed after the sterile microscope sleeve is tightly attached to the microscope arm, reducing noise interference during surgery. The negative pressure state inside the sterile microscope sleeve can be accessed simply by removing the rubber plug, making it easy to remove the sterile microscope sleeve. Moreover, all parts except the sterile microscope sleeve can be reused, reducing the cost of consumables. Due to the cooperation of the spring and the ball head, the spring causes the ball head to lift the sterile microscope sleeve before the air is completely extracted, which can prevent the sterile microscope sleeve from closing the suction hole too early and causing the air extraction to be interrupted. Only after the vacuum is completely drawn can the sterile microscope sleeve have enough air pressure difference to be tightly attached to the suction hole. Attached Figure Description

[0019] See appendix Figure 1-4 This invention relates to a sterile neurosurgical microscope, comprising a microscope 1 and a sterile microscope sleeve 2. A negative pressure suction tube 4 is arranged along the arm 3 of the microscope 1. The tail end of the negative pressure suction tube 4 is sequentially connected to an extension tube 5, a three-way valve 6, and a negative pressure suction device 7. A suction hole 8 is formed on the side wall of the negative pressure suction tube 4. The extension tube 5 and the negative pressure suction device 7 are respectively connected to the first port 9 and the second port 10 of the three-way valve 6. A rubber stopper 12 is provided at the third port 11 of the three-way valve 6. The sterile microscope sleeve 2 is wrapped around the outside of the arm 3 and the negative pressure suction tube 4 with adhesive tape 13. The adhesive tape 13 is tied at both ends of the sterile microscope sleeve 2 to achieve port closure. The front end of the negative pressure suction tube 4 and the suction hole 8 are both located inside the sterile microscope sleeve 2 bound by the adhesive tape 13. The tail end of the negative pressure suction tube 4 extends out of the sterile microscope sleeve 2.

[0020] See Figure 2-4 The negative pressure suction tube 4 protrudes from the outer surface of the microscope arm 3. The lower surface of the negative pressure suction tube 4 is a plane that fits the upper surface of the microscope arm 3, and the inner cross-section of the negative pressure suction tube 4 is a flat ellipse. A spring 14 corresponding to the suction hole 8 is provided inside the negative pressure suction tube 4. The top of the spring 14 is provided with a ball head 15. At the natural length of the spring 14, the ball head 15 partially extends beyond the outer port of the suction hole 8, and the ball head 15 is smaller than the suction hole 8. Due to the cooperation of the spring 14 and the ball head 15, before the air is completely extracted, the spring 14 keeps the ball head 15 in a state of lifting the sterile microscope sleeve 2, avoiding the sterile microscope sleeve 2 from closing the suction hole 8 too early, causing the air extraction to be interrupted. That is, only after the vacuum is completely drawn will the sterile microscope sleeve 2 have enough air pressure difference to stick to the suction hole 8, ensuring the smooth completion of the vacuuming effect inside the sterile microscope sleeve 8.

[0021] The negative pressure suction tube 4 is a rigid tube, with its tail end curved upwards to detach from the endoscope arm 3. The extension tube 5 is a rubber tube, with both ends connected to the negative pressure suction tube 4 and the three-way valve 6 respectively via threaded pipe fittings 16. This facilitates quick connection of the negative pressure suction tube 4, extension tube 5, three-way valve 6, and negative pressure suction device 7, which is beneficial for rapid preoperative preparation.

[0022] The negative pressure suction device 7 is a universal device used in operating rooms and can be quickly connected to the negative pressure suction tube 4. Except for the sterile microscope sleeve 2, all other components are reusable, reducing operating costs.

[0023] See separately Figure 2 In the first specific embodiment shown, the upper surface of the negative pressure suction tube 4 is an arc-shaped surface.

[0024] See separately Figure 3 In the second specific embodiment shown, the upper surface of the negative pressure suction tube 4 includes two planes that meet at an obtuse angle.

[0025] See separately Figure 4 In the third specific embodiment shown, the negative pressure suction tube 4 is embedded in the arm 3, and the outer surface of the negative pressure suction tube 4 is flush with the outer surface of the arm 3.

[0026] All three specific implementation methods described above can ensure a smooth transition between the negative pressure suction tube 4 and the lens arm 3, avoiding dead corners that cannot be tightly bound due to abruptness at the connection between the negative pressure suction tube 4 and the lens arm 3 when the tape 13 is tied, thus improving the airtightness.

[0027] The above description is only presented as a feasible technical solution of this utility model and is not intended as a single limitation on the technical solution itself.
