Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically an adjustable and controllable negative pressure suction device connector. Background Technology

[0002] Neurosurgery is a branch of surgery that, while primarily using surgery for treatment, employs unique neurosurgical research methods to study the human nervous system, including the brain, spinal cord, and peripheral nervous system, as well as related structures such as the skull, scalp, cerebral blood vessels, and meninges, examining injuries, inflammations, tumors, malformations, and certain inherited metabolic disorders or functional disturbances. During neurosurgical procedures, patients often experience significant bleeding at the surgical site, necessitating the use of a controlled negative pressure suction device to remove the accumulated blood and facilitate surgical procedures.

[0003] Most existing neurosurgical controllable suction heads have a fixed direction and cannot be adjusted. When you want to suction objects in different directions in the horizontal plane, you can only change the suction head or rotate the entire suction head, which takes up surgical time and is very inconvenient to operate.

[0004] Therefore, this utility model provides an easily adjustable controllable negative pressure suction device connector to solve the above problems. Utility Model Content

[0005] This invention provides an easily adjustable controllable negative pressure suction device connector, aiming to solve the problems mentioned in the background art, such as the fact that most existing neurosurgical controllable suction device heads have a fixed direction and do not have an adjustable function. When you want to suction objects in different directions in the horizontal plane, you can only replace the suction device head or rotate the entire suction device head, which takes up surgical time and is very inconvenient to operate.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an easily adjustable controllable negative pressure suction device connector, comprising a cylindrical body;

[0007] The cylinder has mounting holes at both its upper and lower ends, through which a suction tube is connected. A locking block is installed on the outer wall of the suction tube, and a locking groove is located at the bottom of the inner cavity of the cylinder. By using the locking groove and locking block, the suction tube moves upward, pulling the locking block out of the groove. The suction tube, along with the locking block, rotates above several grooves. When rotated to the direction required by the surgeon, the suction tube moves downward, pulling the locking block into the nearest groove. This achieves the function of adjusting the direction of the suction tube, avoiding the problem that existing neurosurgical controllable suction heads lack adjustment functionality. When suctioning objects in different directions within the horizontal plane, the suction head must be replaced or the entire suction head rotated, saving surgical time and making suction head adjustment more convenient.

[0008] Preferably, a return spring is installed on the inner end face of the cylinder and outside the suction tube. A ring seat is provided at the lower end of the return spring. A limit groove is formed on the inner wall of the ring seat. A connecting ring is rotatably installed on the ring seat through the limit groove.

[0009] Preferably, the slots are provided in a plurality of places and are arranged in a ring array at the bottom of the inner cavity of the cylinder.

[0010] Preferably, the slot and the block are matched, and the cylinder is fitted with a sealing ring through the lower mounting hole.

[0011] Preferably, a handheld box is installed at the upper end of the cylinder, the side wall of the handheld box has an opening, the opening communicates with the inner wall of the handheld box, a connecting pipe is installed at the upper end of the handheld box, and the upper end of the cylinder extends to the inner wall of the handheld box.

[0012] Preferably, the inner wall of the cylinder is slidably connected to the outer wall of the annular seat.

[0013] Beneficial effects: By setting up slots and blocks, the suction tube moves upward and disengages from the slot along with the block. The suction tube rotates above several slots with the block. When it rotates to the direction required by the surgeon, the suction tube moves downward and enters the nearest slot with the block. This achieves the function of adjusting the direction of the suction tube, avoiding the problem that existing neurosurgical controllable suction head does not have an adjustable direction function. When you want to suction objects in different directions in the horizontal plane, you can only replace the suction head or rotate the entire suction head. This saves surgical time and makes it more convenient to adjust the direction of the suction head. Attached Figure Description

[0019] 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.

[0020] Example

[0021] This embodiment provides an easily adjustable, controllable negative pressure suction device connector, such as... Figure 1-4 As shown, the controllable negative pressure suction device connector includes a cylinder 1;

[0022] The upper and lower ends of the cylinder 1 are provided with mounting holes 11. The cylinder 1 is connected to the suction tube 2 through the mounting holes 11. The outer wall of the suction tube 2 is provided with a locking block 3. The bottom of the inner cavity of the cylinder 1 is provided with a locking groove 12.

[0023] In use, the surgeon squeezes the suction tube 2 upwards, causing the suction tube 2 to move upwards along with the locking block 3. The locking block 3 disengages from the locking slot 12. Then, the surgeon rotates the suction tube 2, causing it to rotate above several locking slots 12. When the lower end of the suction tube 2 rotates to the direction desired by the surgeon, the surgeon pulls the suction tube 2 downwards, causing it to move downwards along with the locking block 3, allowing the locking block 3 to enter the nearest locking slot 12 and lock in place. This enables the surgeon to adjust the direction of the suction tube 2. By covering the opening 41 with a finger, the pressure inside the suction device is reduced to that outside, allowing the suction tube 2 to draw in objects. This avoids the problem that most existing neurosurgical controllable suction devices have fixed directions and lack adjustment capabilities. When the surgeon wants to suction objects in different directions on the horizontal plane, they have to replace the suction device head or rotate the entire suction device head. This saves surgical time and makes adjusting the direction of the suction device head much more convenient.

[0024] In this embodiment, a return spring 6 is installed on the inner end face of the cylinder 1 and outside the suction tube 2. A ring seat 7 is provided at the lower end of the return spring 6. A limiting groove 71 is opened on the inner wall of the ring seat 7. A connecting ring 8 is rotatably installed on the ring seat 7 through the limiting groove 71.

[0025] In this system, the return spring 6, the annular seat 7, and the connecting ring 8 work together to move the suction tube 2 upward with the locking block 3. The locking block 3 drives the connecting ring 8 to move, and the connecting ring 8 drives the annular seat 7 to move. The annular seat 7 then compresses the return spring 6. When the suction tube 2 rotates with the locking block 3, the locking block 3 rotates with the connecting ring 8 in the limiting groove 71. When the locking block 3 enters the corresponding slot 12 downward, the return spring 6's reset movement exerts a reverse thrust on the annular seat 7. Consequently, the annular seat 7 exerts a certain force on the connecting ring 8, and the connecting ring 8 pushes the locking block 3 back, making it tightly locked in the slot 12. Under non-human conditions, this makes it difficult for the locking block 3 to disengage from the slot 12, thus improving the stability of the suction tube 2 after the direction is adjusted.

[0026] In this embodiment, several slots 12 are provided and are arranged in a ring array at the bottom of the inner cavity of the cylinder 1; the slots 12 and the block 3 are adapted to each other, and a sealing ring is installed on the cylinder 1 through the lower mounting hole 11;

[0027] Among them, a sealing ring is installed on the lower mounting hole 11 through the cylinder 1 to increase the sealing of the connection between the liquid suction pipe 2 and the mounting hole 11 and avoid the possibility of liquid leakage from the connection seam between the liquid suction pipe 2 and the cylinder 1.

[0028] In this embodiment, a handheld box 4 is installed at the upper end of the cylindrical body 1. An opening 41 is provided on the side wall of the handheld box 4. The opening 41 communicates with the inner wall of the handheld box 4. A connecting pipe 5 is installed at the upper end of the handheld box 4. The upper end of the cylindrical body 1 extends to the inner wall of the handheld box 4. The inner wall of the cylindrical body 1 is slidably connected to the outer wall of the annular seat 7.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and concept of the present utility model, should be included within the protection scope of the present utility model.
