Abstract
Description
Technical Field
[0001] This utility model relates to an auxiliary device for medical devices, particularly a clamping component for neurosurgical instruments. Background Technology
[0002] During neurosurgical procedures, neuroendoscopic instruments and suction instruments are often used simultaneously. Currently, surgeons use one hand to hold both instruments at the same time, freeing up their other hand. However, various factors (such as the weight of the instruments) cause the instruments to lose their stable position and posture, or prolonged use can lead to hand fatigue and stiffness. Utility Model Content
[0003] In view of the above-mentioned technical problems existing in the prior art, the embodiments of this utility model provide a neurosurgical instrument clip.
[0004] To solve the above-mentioned technical problems, the technical solution adopted in the embodiments of this utility model is as follows:
[0005] A neurosurgical instrument locking device includes: a first locking component and a second locking component. The first locking component has a first locking groove adapted to the outer diameter of a neuroendoscopy tube and extending axially, so that the neuroendoscopy tube is locked in the first locking groove. The second locking component has a second locking groove adapted to the outer diameter of an inspirator tube and extending axially, so that the inspirator tube is locked in the second locking groove. The first locking component is connected to the second locking component.
[0006] Preferably, the first snap-fit component is fixedly connected to the second snap-fit component.
[0007] Preferably, the first snap-fit component and the second snap-fit component are integrally formed, and the opening of the first slot of the first snap-fit component and the opening of the second slot of the second snap-fit component face the same direction.
[0008] Preferably, the first snap-fit component and the second snap-fit component are configured to be movable relative to each other axially.
[0009] Preferably, the first snap-fit component has a dovetail groove extending axially, and the second snap-fit component has a dovetail-shaped strip extending axially, the dovetail-shaped strip being located in the dovetail groove.
[0010] Preferably, the opening of the first slot of the first snap-fit component and the opening of the second slot of the second snap-fit component face the same or opposite directions.
[0011] Preferably, a flexible component is connected between the first snap-fit component and the second snap-fit component to allow the first snap-fit component and the second snap-fit component to be able to twist relative to each other.
[0012] Preferably, the flexible component is a silicone column or a rubber column.
[0013] Compared with the prior art, the beneficial effects of the neurosurgical instrument clip disclosed in this utility model are:
[0014] The clip provided by this invention keeps the neuroendoscope and the suction device connected, thereby greatly reducing the holding force applied by the surgeon to keep the neuroendoscope and the suction device in relative position and / or state. This not only improves the stability of the position and / or posture of the two instruments, but also makes the surgeon's hands more relaxed.

The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.
[0027] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.
[0028] like Figures 1 to 7As shown, an embodiment of this utility model discloses a neurosurgical instrument clip 100. The neurosurgical instrument includes a neuroendoscope 200 and a suction device 300, which are connected together by the clip 100. The clip 100 includes a first locking component 10 and a second locking component 20, both of which are made of plastic material. The first locking component 10 and the second locking component 20 have similar structures. Specifically, the first locking component 100 has a first locking groove 11 extending axially, which is adapted to the outer diameter of the neuroendoscope 200 tube, thereby allowing the neuroendoscope 200 tube to be locked in the first locking groove 11. The second locking component 100 has a second locking groove 21 extending axially, which is adapted to the outer diameter of the neuroendoscope 200 tube, thereby allowing the neuroendoscope 200 tube to be locked in the second locking groove 21. Thus, the neuroendoscope 200 is fixed to the first locking component 10, and the suction device 300 is fixed to the second locking component 20. The first locking component 10 and the second locking component 20 are connected, thereby maintaining the connection between the neuroendoscope 200 and the suction device 300.
[0029] The clip 100 provided by this invention keeps the neuroendoscope 200 and the suction device 300 connected, thereby greatly reducing the holding force applied by the surgeon to keep the neuroendoscope 200 and the suction device 300 in relative position and / or state. This not only improves the stability of the position and / or posture of the two instruments, but also makes the surgeon's hands more comfortable.
[0030] This utility model provides three specific structures for the card 100.
[0031] The first structure of card 100.
[0032] like Figure 1 and Figure 2 As shown, the first snap-fit component 10 and the second snap-fit component 20 are fixedly connected. More preferably, the first snap-fit component 10 and the second snap-fit component 20 are integrally injection molded, and the opening of the first snap-fit groove 11 and the opening of the second snap-fit groove 21 face the same direction. In this way, the neuroendoscopy 200 and the suction device 300 are fixedly connected by being snapped onto the first snap-fit component 10 and the second snap-fit component 20 respectively.
[0033] The clamp 100 of this structure is suitable for certain situations, such as when two devices are required to maintain a fixed relative position and relative posture.
[0034] The second structure of card 100.
[0035] like Figure 3 and Figure 4As shown, the first locking component 10 and the second locking component 20 are connected in a way that allows relative axial movement. Specifically, a dovetail groove 12 is formed on the back of the first locking component 10, which extends axially and passes through the first locking component 10. A dovetail-shaped strip 22 is machined on the back of the second locking component 20, and the dovetail-shaped strip 22 is located in the dovetail groove 12. At this time, the openings of the first locking groove 11 and the second locking groove 21 face opposite directions. Thus, after the neuroendoscope 200 and the suction device 300 are respectively locked onto the first locking component 10 and the second locking component 20, the relative positions of the neuroendoscope 200 and the suction device 300 can be adjusted by sliding the dovetail-shaped strip 22 in the dovetail groove 12, but their relative posture is restricted.
[0036] The clip 100 of this structure is suitable for certain situations, such as when the relative axial position between the end of the neuroendoscope 200 and the end of the suction device 300 needs to be adjusted during the operation.
[0037] The third type of snap-fit structure.
[0038] like Figures 5 to 7 As shown, the first snap-fit component 10 and the second snap-fit component 20 are connected by a flexible component 30. Specifically, the flexible component 30 can be a silicone pillar or a rubber pillar, thereby allowing adjustment of the relative posture between the first snap-fit component 10 and the second snap-fit component 20. In this way, the posture between the neuroendoscope 200 and the inspirator, which are respectively snapped onto the first snap-fit component 10 and the second snap-fit component 20, can be adjusted.
[0039] The clamp 100 of this structure is suitable for certain situations, such as when the position between the ends of two devices needs to be adjusted at all times, for example, to adjust the position of the ends for the purpose of avoiding tissue.
