Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a surgical suction tube for craniocerebral and spinal cord surgery that can be manually controlled. Background Technology

[0002] Craniotomy and spinal cord surgery is a type of surgical procedure performed on diseases of the brain, spinal cord, and related nervous systems. It is usually performed by neurosurgeons. The main purpose of this type of surgery is to treat or alleviate diseases, injuries, or abnormalities related to the central nervous system, such as brain tumors, cerebral aneurysms, spinal cord injuries, and nerve root compression. In order to allow surgeons to adjust the suction at any time according to the specific circumstances of the surgery and avoid unnecessary damage to healthy tissues, thereby improving the safety of the surgery, it is necessary to use a manually controllable craniotomy and spinal cord surgery suction tube.

[0003] In the use of suction tubes in traditional craniocerebral and spinal cord surgery, when it is necessary to increase suction, the doctor presses the control button on the handle, and the suction system increases suction through the negative pressure device, thereby quickly removing the fluid from the surgical area.

[0004] In the process of adjusting the suction, the valve needs to be turned to change the flow rate and thus adjust the suction force. However, the valve is fixed by friction during use, which makes it easy for the valve position to change during suction, resulting in changes in the suction force. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a manually controllable suction tube for craniocerebral and spinal cord surgery, which aims to improve the problem that the valve position is easily changed during suction, resulting in changes in suction force.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a hand-controlled aspiration tube for craniocerebral and spinal cord surgery, comprising an aspiration tube, a control sleeve fixedly connected to one end of the aspiration tube, a sealing ball rotatably connected inside the control sleeve, an adjusting valve fixedly connected to the outer wall of the sealing ball, the adjusting valve rotatably connected inside the control sleeve, a limiting post fixedly connected to the outer wall of the sealing ball, the limiting post rotatably connected inside the control sleeve, a positioning groove arranged in a ring array inside the limiting post, and a limiting component provided inside the control sleeve to prevent the sealing ball from rotating arbitrarily.

[0007] As a further description of the above technical solution:

[0008] The limiting component includes an N-shaped support rod and a locking post. The N-shaped support rod is fixedly connected to the outer wall of the locking post, and one end of the N-shaped support rod is fixedly connected to the inside of the control sleeve. The locking post is fitted into the positioning groove.

[0009] As a further description of the above technical solution:

[0010] The other end of the suction tube has a slot and a vent hole.

[0011] As a further description of the above technical solution:

[0012] An adapter is provided at one end of the suction tube, and a pinch block is fixedly connected to the outer wall of the adapter.

[0013] As a further description of the above technical solution:

[0014] One end of the adapter is fixedly connected to a threaded head, which is threaded into the inside of the suction tube.

[0015] As a further description of the above technical solution:

[0016] A sealing ring is fixedly connected to one end of the threaded head, and the sealing ring fits inside the suction tube.

[0017] As a further description of the above technical solution:

[0018] The adapter has a second sealing ring fixedly connected inside, and the second sealing ring is tapered and gradually tapers towards the inside of the adapter.

[0019] As a further description of the above technical solution:

[0020] The adapter has protrusions fixedly connected inside, and the protrusions are arranged in a ring array and fixedly connected inside the adapter.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the bottom of the sealing ball is first limited in the control sleeve by the limiting post, and the locking post at one end of the N-shaped support rod is embedded in the positioning groove in the control sleeve, which achieves the effect of limiting the valve, solves the problem that the valve position is easy to change during suction, resulting in changes in suction force, and improves the stability of the suction tube for craniocerebral and spinal cord surgery.

[0023] 2. In this utility model, the hose and the adapter are sealed by a second sealing ring. The second sealing ring is conical and gradually narrows in diameter towards the inside of the adapter. At the same time, the adapter and the hose increase friction through protrusions, which improves the connection stability. This solves the problem that when the suction tube for intracranial and spinal cord surgery is connected to the suction machine by simply plugging and unplugging, it is easy to separate. This improves the practicality of the suction tube for intracranial and spinal cord surgery. Attached Figure Description

[0031] 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.

[0032] Reference Figures 1-5 This utility model provides an embodiment of a hand-controlled aspiration tube for craniocerebral and spinal cord surgery, comprising an aspiration tube 1, a control sleeve 2 fixedly connected to one end of the aspiration tube 1, a sealing ball 3 rotatably connected inside the control sleeve 2, an adjusting valve 4 fixedly connected to the outer wall of the sealing ball 3, the adjusting valve 4 being rotatably connected inside the control sleeve 2 for adjusting the aspiration flow rate, a limiting post 5 fixedly connected to the outer wall of the sealing ball 3, the limiting post 5 being rotatably connected inside the control sleeve 2, and having positioning grooves 6 arranged in a ring array inside, these positioning grooves 6 being used to cooperate with the limiting component to prevent the sealing ball 3 from rotating arbitrarily and to ensure adjustment accuracy, the limiting component including an N-shaped support rod 7 and a locking post 8, wherein the N-shaped support rod 7 is fixedly connected to one end of the outer wall of the locking post 8, the other end of the N-shaped support rod 7 is fixedly connected to the inside of the control sleeve 2, the locking post 8 is fitted inside the positioning groove 6, the structure of the N-shaped support rod 7 stabilizes the locking post 8, keeping it stable in the positioning groove 6, preventing the sealing ball 3 from shifting during adjustment, thereby ensuring the accuracy and reliability of the operation;

[0033] Specifically, when it is necessary to adjust the suction flow rate of suction tube 1, simply turn the regulating valve 4 gently. The rotation of the valve will cause the internal sealing ball 3 to rotate smoothly within the control sleeve 2. The sealing ball 3 is precisely designed with a through hole inside. By adjusting the rotation angle of the sealing ball 3, the gap between the through hole and the control sleeve 2 can be controlled, thereby achieving precise adjustment of the suction force. To ensure that the sealing ball 3 does not shift its position during rotation, the bottom of the sealing ball 3 is limited and fixed within the control sleeve 2 by a limiting post 5. At the same time, the N-shaped support rod 7 inside the control sleeve 2, through its elastic design, drives the locking post 8 to embed and position itself. Inside the groove 6, when the sealing ball 3 rotates, the locking post 8 will precisely engage in the positioning groove 6, forming a pre-positioning of the limiting post 5, preventing the sealing ball 3 from being misaligned and causing incorrect suction adjustment. The N-shaped support rod 7 has a certain degree of elasticity, which can ensure that the locking post 8 is stably engaged in the positioning groove 6, further enhancing the limiting effect on the valve. During the suction process, the end of the suction tube 1 is designed with a slot 9 and a vent hole 10. This design effectively avoids the risk of the suction tube 1 port being blocked, and prevents the patient's tissue from being blocked due to excessive suction, greatly improving the safety and reliability of the operation during the procedure.

[0034] Reference Figure 4 The other end of the suction tube 1 has a slot 9 to provide a certain flow space and prevent blockage during suction. The other end of the suction tube 1 also has vent holes 10 to maintain airflow during suction and prevent excessive negative pressure caused by overly tight suction. One end of the suction tube 1 is equipped with an adapter 11 for connecting to a suction device. A pinch block 12 is fixedly connected to the outer wall of the adapter 11 to facilitate manual operation and help the user grip and install the adapter 11 more securely. One end of the adapter 11 is fixedly connected to a threaded head 13, which is secured by a threaded connection. The connector 13 is fixed inside the suction tube 1 to ensure a firm connection. One end of the threaded head 13 is also fixedly connected to a sealing ring 14. The sealing ring 14 is tightly attached to the inside of the suction tube 1 to ensure the sealing of the connection and prevent gas or liquid leakage. The connector 11 is also fixedly connected to a sealing ring 15. The sealing ring 15 is tapered and gradually tapers towards the inside of the connector 11 to effectively enhance the sealing of the hose. The connector 11 is also fixedly connected to a protrusion 16. These protrusions 16 are arranged in a ring array on the inner wall of the connector 11 to increase the friction with the hose, prevent the hose from falling off, and ensure a firm and reliable connection.

[0035] Specifically, when connecting the suction tube 1 to the suction device, first, manually pinch the pinch block 12 to gently hold the adapter 11. Then, carefully screw the threaded head 13 of the adapter 11 into the suction tube 1, so that the adapter 11 and the suction tube 1 are firmly sealed by the precision sealing ring 14. The sealing ring 14 can effectively prevent the leakage of air or liquid, thereby ensuring the stability of suction. Next, connect the suction machine's hose to the adapter 11. Simply insert the hose into the adapter 11. The sealing is achieved with the double protection of the sealing ring 15. The sealing ring 15 is tapered, so that the diameter gradually decreases during insertion, ensuring that the hose and the adapter 11 fit tightly without any gaps. At the same time, the carefully designed protrusions 16 between the adapter 11 and the hose increase the friction, further improving the stability of the connection and preventing the hose from accidentally coming off during the operation. This ensures a firm connection between the suction tube 1 and the suction device, greatly improving the safety and operational reliability of the entire system.

[0036] Working Principle: When using this hand-controlled suction tube for craniocerebral and spinal cord surgery, firstly, when connecting the suction tube 1 to the suction device, pinch the adapter 11 with the pinch block 12. Then, screw the adapter 11 into the suction tube 1 through the threaded head 13, sealing the adapter 11 and the suction tube 1 with a sealing ring 14. Next, connect the suction machine's hose to the adapter 11 by directly inserting it into the adapter 11, sealing the hose and adapter 11 with a sealing ring 15. The sealing ring 15 is tapered, gradually decreasing in diameter towards the inside of the adapter 11. Simultaneously, the adapter 11 and the hose increase friction through protrusions 16, preventing the hose from detaching from the adapter 11 and thus improving the connection strength. Then, when adjusting the suction flow rate of the suction tube 1... Simply rotate the regulating valve 4 to rotate the sealing ball 3 within the control sleeve 2. The sealing ball 3 has a through hole. When the sealing ball 3 rotates, the gap between the through hole and the control sleeve 2 is controlled to adjust the suction force. The bottom of the sealing ball 3 is limited within the control sleeve 2 by the limiting post 5. Furthermore, the locking post 8 at one end of the N-shaped support rod 7 is embedded in the positioning groove 6 within the control sleeve 2. When the sealing ball 3 rotates, the locking post 8 is engaged with the positioning groove 6 to pre-position the limiting post 5, preventing the sealing ball 3 from being misaligned and causing incorrect suction. The N-shaped support rod 7 is N-shaped and has a certain elasticity, which can drive the locking post 8 to be stably engaged within the positioning groove 6, achieving the effect of limiting the valve. The slot 9 and vent 10 at the end of the suction tube 1 can prevent the port from being blocked, thus preventing the patient's body from being sucked up and blocked.

[0037] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
