Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, in particular to a neurosurgery clinical tumor specimen collection device. Background Art

[0002] In the actual clinical diagnosis and treatment of neurosurgery, in order to ensure the accurate judgment of the nature of the tumor, it is necessary to conduct post-sampling testing. When sampling deeper tumors, endoscopic-assisted sampling is a common sampling method. For tumors in the ventricular system or adjacent to the ventricle, doctors usually use endoscopic technology for biopsy, which can accurately sample with the assistance of a visual probe to reduce damage to surrounding brain tissue. Neurosurgery involves the diagnosis and treatment of the nervous system of the brain, and it is necessary to ensure the safety of sampling. The current neurosurgery clinical tumor specimen collection device is mainly operated by a doctor holding an endoscope. The feeding of the endoscope mainly depends on the doctor's hand operation, with limited operating accuracy, and it is not convenient to provide an intuitive prompt for the sampling feeding pressure. Excessive feeding pressure can easily damage nerves and even cause local bleeding. At the same time, for patients with cerebrospinal fluid, the surgical field is not good during sampling, and it is not easy to control the formation of a good surgical field. The traditional drainage method of direct flushing is prone to leakage and contamination of cerebrospinal fluid pollutants. At the same time, cerebrospinal fluid reflux is prone to infection at the sampling site and other hidden dangers. It is also not convenient to gradually discharge cerebrospinal fluid, which can easily lead to excessive discharge of cerebrospinal fluid and cause low intracranial pressure syndrome.

The structure can ensure the safety of sampling. At the same time, the structure adopts the expansion positioning member 3 flexible positioning method to prevent damage to the brain wall and further ensure safety. The structure is simple to control and can freely control the feeding amount according to needs. It can be slowly advanced by air pressure to ensure safety. By inserting the laparoscope body 101 into the sampling channel of the patient's brain, such as meningioma, if the location is deep, it is close to the laparoscope body 101. Near the brainstem, sampling with a traditional sampling needle is very likely to damage the brain. By placing the positioning inflation tube 303 between the left and right cerebral sutures and inflating a small amount of air through an external air pump, the stability of the positioning film sleeve 302 can be maintained. The positioning inflation tube 303 can also be placed on the patient's skull opening for positioning. It can be adjusted according to the actual sampling depth and tumor location. When the working inflation ball 4011 approaches sensitive locations such as the brainstem, the air pump external to the air guide tube 204 is started to inflate the telescopic bellows 202. At this time, under the action of air pressure, the telescopic bellows 202 can slowly expand and extend, driving the pneumatic propulsion ring 201 to pull the laparoscope body 101 to move, thereby slowly feeding and moving the laparoscope body 101 from between the left and right meninges, which is more stable.

[0035] The telescopic pulling member 4 includes: a telescopic tube 401, a working expansion ball 4011, an inner support sponge 4012, a limit ring 402 and a spring 403.

At the same time, this structure adopts a closed drainage method to achieve slow drainage in different areas, avoiding the rapid reduction of brain pressure caused by the rapid drainage of cerebrospinal fluid, causing the problem of low intracranial pressure syndrome, and reducing the risk of cerebrospinal fluid overflow, reducing the risk of cerebrospinal fluid contamination and brain infection, which can improve safety. At the same time, the working expansion ball 4011 used can also be easily expanded and supported between the left and right brains, increasing the surgical field of the doctor's operation and improving the quality of the operation. The working expansion ball 4011 that can be pulled and moved can be extended into the brain support and then retracted into the cavity. The mirror body 101 can further ensure the quality of the operation and prevent the working expansion ball 4011 from blocking the operation of the laparoscope body 101. The structure is more reasonable. The ventilation of the air pump connected to the telescopic tube 401 is controlled to control the expansion of the working expansion ball 4011 to support the meninges and increase the surgical field. After the working expansion ball 4011 is expanded and positioned, the internal exhaust of the telescopic bellows 202 can be controlled to cooperate with the traction of the reset spring 203 to retract the laparoscope body 101. At this time, there is a distance between the end of the laparoscope body 101 and the working expansion ball 4011, which can meet the sampling requirements.

After the working expansion ball 4011 is expanded and positioned, the sampling forceps in the working channel 1012 can be used for sampling. The torsion spring 503 is used to apply elastic force to control the swinging rotating block 501 to be centered when the two electromagnets 102 are not energized.

[0037] Embodiment 2, on the basis of embodiment 1, the extrusion detection member 6 comprises: a connecting air pipe 601, a three-way valve 602, a detection tube 603 and a supporting air pipe 604, the connecting air pipe 601 is fixedly installed at the end of the telescopic tube 401; the connecting air pipe 601 is fixedly connected with a three-way valve 602; the detection tube 603 is installed on the three-way valve 602; the supporting air pipe 604 is installed on the three-way valve 602; the supporting air pipe 604 is externally connected with an air pump; the extrusion detection member 6 also comprises: an air pressure pipe 605, an air pressure piston 606, anti-accidental touch spring 6061, the air pressure tube 605 is fixedly installed at the end of the detection tube 603; the air pressure piston 606 is slidably installed inside the air pressure tube 605; the anti-accidental touch spring 6061 is sleeved inside the air pressure tube 605; the end of the anti-accidental touch spring 6061 is fixedly installed on the air pressure piston 606; the other end of the anti-accidental touch spring 6061 is fixedly installed inside the air pressure tube 605; the extrusion detection part 6 also includes: an alarm switch 607 and a prompt light 608, the alarm switch 607 is fixedly installed on the air pressure tube 6 05 inside; the alarm switch 607 is located on the inside of the anti-mistouch spring 6061; the alarm switch 607 is aligned with the air pressure piston 606; the prompt light 608 is fixedly installed on the air pressure tube 605; the alarm switch 607 is electrically connected to the prompt light 608; the prompt light 608 is used to prompt abnormal pressure. The use of the extrusion detection member 6 can further improve the safety of the present structure during the actual sampling operation by means of pressure detection. It can cooperate with the working expansion ball 4011. If the pressure is too high, prompts can be given in time to avoid squeezing and damaging the brain. The present structure has accurate detection and can improve the quality of surgery. At the same time, the intuitive prompt method is adopted to avoid the problem of high misjudgment rate of relying on the doctor's hand feeling. When the working expansion ball 4011 moves into the sampling cavity or the working expansion ball 4011 is in place and expands to fit the left and right brain meninges, once the working expansion ball 4011 is excessively squeezed by the brain stem, or the working expansion ball 4011 is excessively expanded and squeezes the left and right brains, the prompt light 608 can light up to prompt, and the operation is simple and convenient.

[0038] The working principle of this embodiment is as follows: first, the positioning inflation tube 303 is placed between the left and right cerebral sutures, and a small amount of air is inflated through an external air pump to maintain the stability of the positioning film sleeve 302. The positioning inflation tube 303 can also be placed on the patient's skull opening for positioning, and can be adjusted according to the actual sampling depth and tumor location. When the working inflation ball 4011 approaches sensitive locations such as the brain stem, fine-tuning is performed, and the air pump external to the air guide tube 204 is started to inflate the telescopic bellows 202. At this time, under the action of air pressure, the telescopic bellows 202 can slowly expand and extend, driving the pneumatic propulsion ring 201 to pull the laparoscope body 101 to move, so as to achieve the slow feeding and movement of the laparoscope body 101 from between the left and right meninges, which is more stable. Subsequently, the probe of the laparoscope body 101 itself can be used to observe the tumor location, and the sampling forceps in the working channel 1012 can be used to perform sampling using existing mature laparoscope technology; the working inflation ball 4011 is placed in the working channel 1012, and the sampling forceps in the working channel 1012 are used to perform sampling. It is placed at the front end of the laparoscope body 101. When the laparoscope body 101 enters the sampling cavity, the working expansion ball 4011 is pushed into the sampling cavity together. At this time, the air pump connected to the telescopic tube 401 can be controlled to ventilate, and the working expansion ball 4011 can be controlled to expand to support the meninges and increase the surgical field. After the working expansion ball 4011 is expanded and positioned, the internal exhaust of the telescopic bellows 202 can be controlled, and the laparoscope body 101 can be retracted a certain distance in coordination with the pulling of the reset tension spring 203. At this time, there is a distance between the end of the laparoscope body 101 and the working expansion ball 4011, which can meet the sampling requirements. The telescopic tube 401 can be pulled to fine-tune the position of the working expansion ball 4011; if the telescopic tube 401 blocks the sampling clamp, one of the two electromagnets 102 can be controlled to be energized according to the blocking position, and the magnetic iron sheet 504 on the same side can be magnetically attracted, so as to drive the swinging rotating block 501 to rotate and toggle the telescopic tube 401, so as to control the telescopic tube 401 not to block the sampling clamp for sampling;

[0039] When the working expansion ball 4011 moves into the sampling cavity or after the working expansion ball 4011 is in place and expands to fit the left and right brain meninges, the three-way valve 602 can be rotated to close the detection tube 603, and the air pump connected to the external support air pipe 604 can be turned on. At this time, the air pressure in the working expansion ball 4011 is connected to the air pressure pipe 605. Once the working expansion ball 4011 is excessively squeezed by the brain stem, or the working expansion ball 4011 is excessively expanded and squeezes the left and right brains, the air pressure will push the air pressure piston 606 to compress the anti-mistouch spring 6061, and then touch the squeeze alarm switch 607, and control the prompt light 608 to light up to prompt, thereby realizing the detection work.
