[0024] 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.

[0025] Please see Figure 1-3 This embodiment provides an aspirator with a composite nerve stimulation probe, including an aspiration tube 100 for aspirating blood, exudate, and tumor tissue within the surgical field of view. The tail of the aspiration tube 100 is connected to a holding tube 200, and the end of the holding tube 200 is connected to a connector for connecting to an aspiration device. The lower front end of the aspiration tube 100 has a stimulation probe 402. The holding tube 200 is internally provided with an electrical connection component for connecting the stimulation probe 402 to the device. Through the arrangement of the aspiration tube 100 and the stimulation probe 402, while aspirating blood, exudate, and some tumor tissue within the surgical field of view, the nerve functional area can be automatically identified, preventing damage to normal brain tissue. During the operation, the aspiration function and the nerve monitoring function are performed simultaneously, improving the accuracy and efficiency of nerve function localization, and significantly improving the surgical quality of neurosurgeons.

[0026] Among them, the suction device is a negative pressure source. Common negative pressure sources include central negative pressure systems and portable negative pressure suction devices. In actual operation, the appropriate one can be selected according to the needs. Central negative pressure systems and portable negative pressure suction devices are technical means that are commonplace for those skilled in the art. Their specific working principles and structures will not be elaborated on here.

[0027] The device connected to the stimulation probe 402 includes, but is not limited to, one of the following: an electromyography evoked potential instrument, a nerve stimulator, or a transcranial magnetic stimulator.

[0028] The grip tube 200 has three sets of grooves 201 on its surface, which are arranged in a ring array. The grooves 201 increase the friction when medical staff hold the grip, making the grip more stable and less prone to slipping. This helps to improve the accuracy and stability of surgical operations and reduce surgical errors that may be caused by hand slippage. At the same time, this design also improves the comfort of medical staff holding the grip and reduces hand fatigue during long-term surgery.

[0029] A side hole 202 is provided inside the groove 201 on the upper side and near the suction tube 100. The inner cavity of the side hole 202 is connected to the inner cavity of the holding tube 200. The side hole 202 can be used to inject drugs, irrigation fluid or expel gas to meet various needs during surgery. At the same time, by controlling the area of ​​the side hole 202, the suction force of the negative pressure can be adjusted, so as to adjust the suction speed of blood and exudate according to different needs.

[0030] The connector includes an insertion tube 300 connected to the tail of the holding tube 200. Several sets of rubber rings 301 are fixedly sleeved on the outer circular surface of the insertion tube 300. The outer circular surface of each set of rubber rings 301 is rounded at the tail. Through the connection, the insertion tube 300 at the tail of the holding tube 200 is fixedly sleeved with several sets of rubber rings 301. The rubber rings 301 can increase the sealing of the connection between the insertion tube 300 and the suction device, prevent air leakage during suction, and ensure that a stable negative pressure can be maintained in the suction tube 100, thereby effectively suctioning out blood, exudate and tumor tissue in the surgical area. At the same time, the rubber rings 301 can also increase the friction, making the connection between the insertion tube 300 and the suction device more secure and less likely to fall off, thus improving the reliability of the device during the operation.

[0031] The electrical connection assembly includes a wire 400 disposed inside the lower wall of the suction tube 100. One end of the wire 400 is electrically connected to the input end of the stimulation probe 402, and the other end of the wire 400 extends towards the tail and passes through the holding tube 200. The end of the wire 400 located outside the holding tube 200 is electrically connected to an external interface 401. By setting the electrical connection assembly, the wire 400 is disposed inside the lower wall of the suction tube 100, connecting the stimulation probe 402 to the external interface 401. This not only ensures stable transmission of electrical signals but also avoids potential damage or interference to the wire 400 if it is exposed to the outside. At the same time, the external interface 401 facilitates connection with various external devices, giving the device better compatibility and expandability, and enabling it to adapt to different surgical needs and external device configurations.

[0032] Working principle;

[0033] During operation, the suction device is first connected to the connector. The negative pressure generated by the suction device is transmitted through the holding tube 200 to the suction tube 100, which draws the blood, exudate and tumor tissue in the surgical field into the suction tube 100, thereby cleaning the surgical area.

[0034] Meanwhile, the stimulation probe 402 is located at the lower end of the suction tube 100. When an external device inputs an electrical signal through the external interface 401, the electrical signal is transmitted to the stimulation probe 402 along the wire 400, causing it to produce a corresponding stimulation effect. At the same time, it monitors nerve function in real time and assists in surgical operations.

[0035] In terms of gripping operation, the grip tube 200 has three sets of grooves 201 arranged in a ring array on its surface, which makes it convenient for medical staff to grip stably and increases comfort.

[0036] The side hole 202 near the suction tube 100 in the upper groove 201 has an inner cavity that communicates with the inner cavity of the holding tube 200. It can be used to inject drugs, irrigation fluid, or expel gas to meet various needs during surgery. At the same time, when the area of ​​the side hole 202 decreases, the resistance of gas passing through the side hole 202 increases. Since the negative pressure in the suction tube 100 is generated by the suction device, under the condition of a constant total negative pressure, the increased resistance of the side hole 202 will cause more negative pressure to act on the suction port at the front end of the suction tube 100, thereby increasing the suction force on the oozing blood and accelerating the suction speed. Conversely, when the area of ​​the side hole 202 increases, gas passes through the side hole 202 more easily, which will divert some of the negative pressure, making the negative pressure acting on the suction port relatively smaller, and the speed of suctioning the oozing blood will slow down.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
