Description

Neural scope and aspirator fixing device

[ field of technology ]

The utility model relates to the technical field of medical instruments, in particular to a fixing device for a neuroendoscope and an aspirator.

[ background Art ]

Currently, the neuroendoscopic technology has been rapidly developed in neurosurgery, and is widely applied and accepted in not only the traditional treatment of ventricular and skull base diseases, but also a plurality of neurosurgery fields. The working conditions of the endoscope require the presence of an operative channel and a cavity, the channel being intended for passage of the endoscope therethrough, the cavity being naturally available, or being disease-causing or operative, while the cavity requires sufficient space to enable the endoscope to view surrounding structures and to enable safe and effective operative procedures to be performed therein. The prior endoscope mainly plays an auxiliary observation role, and can be operated by a single person and an assistant, along with the gradual expansion of the technical development and application range, the main current practice is to match the operation by the operator and the assistant, namely, the operation of 'two persons and four hands', the operation of holding the endoscope and flushing by the assistant, and the operation of holding the instrument by the operator. The surgical mode needs that the operator and the assistant have enough expertise and under-lens training at the same time and are closely matched to be perfectly implemented. The current surgical approach that attempts to hold both the endoscope and the aspirator with one hand is called "chopsticks technique". The technique can perfectly implement the operation by a single person theoretically without assistant cooperation, thereby greatly reducing the risk of the operation caused by the error of cooperation; however, the difficulty of the technology is far better than that of using chopsticks, one hand needs to keep the stability of the holding mirror and has the flexibility of the aspirator, and the aspirator can be used for matching with the other hand of instruments to operate at any time according to the condition in operation. Because most neurosurgeons are right-handed, the use of left-handed mirrors, right-handed instruments, and the high demands on left-handed flexibility limit the use of this technique. Most of the existing endoscopes and attractors are separated, two instruments are needed to be held by one hand, and difficulty is high. If the endoscope and the aspirator are simply fixed, the endoscope and the aspirator are not easy to move, and the flexibility is greatly insufficient. And if the endoscope with the controllable suction channel is redesigned, the cost of device updating is huge. For the problems in the related art, no effective solution has been proposed at present.

Chinese patent application: CN112274100a, bulletin day: 2021.01.29A neuroendoscope aspirator bayonet is disclosed, including the buckle body, the inside of buckle body is provided with the wash pipe, the buckle body is two sets of integrative, the one end buckle of buckle body can with endoscope camera lens between looks adaptation, the other end buckle of buckle body can with the operation suction pipe between looks adaptation, the material of buckle body is the stainless steel, the length of buckle body is 8.5cm. The advantages are that: the suction device is used for clamping the suction device in the process of performing the neuroendoscopic surgery, clamping the endoscope lens, changing the two-hand operation of a hand-held mirror for observation and a hand-held suction device in the endoscopic surgery into one-hand operation, and the other hand can perform other operations, thereby increasing the convenience of the neuroendoscopic surgery, reducing the possibility of errors, increasing the use effect and being beneficial to long-term use. Although the device can combine the neuroendoscope and the aspirator together for single-hand use, the angle between the neuroendoscope and the aspirator can not be flexibly adjusted during use, and the operation is easy to influence.

Chinese patent application: CN115153385a, bulletin day: 2022.10.11A chopstick type holding device of a neuroendoscope and an aspirator, wherein a neuroendoscope cavity is penetrated on a neuroendoscope bracket, and an upper finger ring is integrally formed at the upper end of the neuroendoscope bracket; the suction device bracket is provided with a suction device cavity and a hook-shaped rod which is integrally formed at the lower end, the free end of the hook-shaped rod is bent to form a rectangular lantern ring, and the suction device positioning sleeve and the rectangular lantern ring are distributed at the two ends of the suction device bracket; a guide groove is cut on the nerve endoscope bracket along the length direction of the nerve endoscope bracket, the root of the guide groove is circular, the opening part is in a shape like a Chinese character '<', and the diameter of the root of the guide groove is larger than the gap of the starting part of the opening part along the section direction; the suction device also comprises a connecting device with one end movably connected with the guide groove and the other end fixedly connected with the suction device bracket. The advantages are that: the doctor can control the neuroendoscope and the aspirator by one hand, and can realize the relative displacement of the two instruments. Although the device can control two instruments by a single handle and can realize the relative displacement between the two instruments, the device has complex structure, more parts and large connecting part volume, and can influence the light channel in operation and the view field of the operator.

In view of the foregoing, there is a need for a neuroendoscope and aspirator fixing device that not only changes the angle and relative displacement between the two instruments, but also does not affect the light path during surgery, does not obstruct the view of the operative field of view of the operator, and is highly operable, simple and practical.
