Description

Technical Field

[0001] This utility model relates to the field of neuroendoscopy, and in particular to a contact-type neuroendoscopic auxiliary fixation device. Background Technology

[0002] Contact neuroendoscopic imaging instruments have effectively solved the problem of accurately locating cerebral hematomas. After the hematoma is located, it is removed using a suction device under the imaging conditions of the contact neuroendoscopy.

[0003] Currently, contact neuroendoscopy cannot be fixed after the hematoma location is confirmed. Doctors use both hands to operate the contact neuroendoscopy and suction device separately to remove the hematoma; or, doctors use a gesture similar to holding chopsticks to relatively fix the contact neuroendoscopy and then operate the suction device separately.

[0004] However, whether operating with one or two hands, it requires a high level of skill from the doctor, which can affect the efficiency of eliminating hematoma. At the same time, since the contact neuroendoscopy is not absolutely fixed, there will still be some shaking during the operation, and the doctor will feel the screen shaking, which can easily lead to dizziness. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a contact-type neuroendoscopy-assisted fixation device, which aims to improve the problem in the prior art that "the contact-type neuroendoscopy cannot be fixed after the hematoma location is confirmed, which is inconvenient during operation and easily causes dizziness in doctors".

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a contact-type neuroendoscopy-assisted fixation device, comprising a positioning sleeve, a fixing component provided on the upper surface of the positioning sleeve, the fixing component comprising a support plate, the support plate being fixedly connected to the upper surface of the positioning sleeve, a movable plate provided on the upper surface of the support plate, a through groove provided on the upper surface of the movable plate, the through groove penetrating the right surface of the movable plate, a locking block being fixedly connected to the lower surface of the movable plate near the front of the through groove, a slot provided on the upper surface of the support plate, the inner wall of the slot being provided with a locking groove adapted to the locking block, a guide plate being fixedly connected to the left surface of the movable plate, and a buckle being rotatably connected to the front surface of the guide plate via a connecting component.

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

[0008] The fixing component also includes a positioning block, the upper surface of which is fixedly connected to the lower surface of the moving plate near the rear of the through groove.

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

[0010] The connecting assembly includes a fixing seat, which is fixedly connected to the left surface of the guide plate, and a rotating shaft is rotatably connected to the inner wall of the fixing seat.

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

[0012] The outer wall of the rotating shaft is rotatably connected to a rotating seat, and the rotating seat is fixedly connected to the outer wall of the buckle.

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

[0014] A rubber sleeve is fixedly connected to the outer wall of the rotating shaft, and a receiving groove adapted to the rubber sleeve is provided on the inner wall of the rotating seat.

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

[0016] The fixed base is provided in multiple sets, and the multiple sets of fixed bases are arranged symmetrically about the center line of the rotating base as the axis of symmetry.

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

[0018] The card block is L-shaped, and the edge of the moving plate is arc-shaped.

[0019] This utility model has the following beneficial effects:

[0020] 1. In this utility model, by setting a fixing component, the neuroendoscope can be clipped into the buckle during the examination. After locating the hematoma, the moving plate can be pressed to bend it towards the center, which will cause the locking block and the positioning plate to move closer together. Then, the locking block and the positioning plate can be inserted into the slot. After releasing the moving plate, the moving plate will return to its original position, which will cause the locking block to be inserted into the slot. This fixes the neuroendoscope in place. This is more convenient to use and can reduce the impact of neuroendoscope shaking on the operator.

[0021] 2. In this utility model, by setting a connecting component with a damping effect, after the approximate position of the neuroendoscope is fixed, if it is necessary to make a fine adjustment to its position, the buckle can be moved to rotate around the rotating shaft. When the operator stops moving the buckle, the rubber sleeve will squeeze the inner wall of the rotating seat to generate friction, thus preventing the buckle from rotating randomly, which makes fine adjustment more convenient.

[0027] 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.

[0028] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a contact-type neuroendoscopy-assisted fixation device, comprising a positioning sleeve 1 for guiding the movement of the neuroendoscopy, a fixation assembly 4 for supporting the neuroendoscopy on the upper surface of the positioning sleeve 1, the fixation assembly 4 including a support plate 45 for supporting the entire fixation assembly 4, the support plate 45 being fixedly connected to the upper surface of the positioning sleeve 1, and the support plate 45 being moved along with the positioning sleeve 1. A moving plate 41 for moving the neuroendoscopy is provided on the upper surface of the support plate 45, the moving plate 41 having a through groove 42 on its upper surface, the moving plate 41 being made of an elastic material with elastic deformation capability, and the moving plate 41 being forced to deform inward by pressing it, while the through groove 42 can... To provide space for the deformation of the movable plate 41, a through groove 42 extends through the right surface of the movable plate 41. A locking block 44 for fixing the movable plate 41 is fixedly connected to the lower surface of the movable plate 41 near the front of the through groove 42. A slot 46 for the locking block 44 to pass through the support plate 45 is provided on the upper surface of the support plate 45. A slot 47 adapted to the locking block 44 is provided on the inner wall of the slot 46. When the locking block 44 is inserted into the slot 47, the locking block 44 will be restricted from moving upward. At the same time, the movable plate 41 will also be fixed on the upper surface of the support plate 45. A guide plate 48 for guiding the insertion of the neuroendoscopy is fixedly connected to the left surface of the movable plate 41. A buckle 2 for fixing the neuroendoscopy is rotatably connected to the front surface of the guide plate 48 through the connecting assembly 3.

[0029] Reference Figure 1 - Figure 3The fixing component 4 also includes a positioning block 43 for positioning the front and rear positions of the moving plate 41. The upper surface of the positioning block 43 is fixedly connected to the lower surface of the moving plate 41 near the rear of the through slot 42. The positioning block 43 is a vertical plate and its length is longer than the positioning block 43. With the help of the positioning block 43, the locking block 44 can be quickly aligned with the slot 46. The connecting component 3 includes a fixing seat 31 for supporting the overall connecting component 3. The fixing seat 31 is fixedly connected to the left surface of the guide plate 48. When the guide plate 48 moves, the fixing seat 31 will also be driven to move synchronously. The inner wall of the fixing seat 31 is rotatably connected to a rotating shaft 32 for supporting the rotation of the rotating seat 33. The outer wall of the rotating shaft 32 is rotatably connected to a rotating seat 33 for supporting the rotation of the buckle 2. The rotating seat 33 is fixedly connected to the outer wall of the buckle 2.

[0030] Reference Figure 1 - Figure 3 The outer wall of the rotating shaft 32 is fixedly connected with a rubber sleeve 35 to restrict the rotation of the buckle 2. The inner wall of the rotating seat 33 is provided with a receiving groove 34 that matches the rubber sleeve 35. By squeezing the inner wall of the receiving groove 34 with the rubber sleeve 35, a large friction force can be provided, thus restricting the rotating seat 33 from rotating freely on the outer wall of the rotating shaft 32. Multiple sets of fixed seats 31 are provided. The multiple sets of fixed seats 31 are symmetrically arranged up and down with the center line of the rotating seat 33 as the axis of symmetry. The two sets of fixed seats 31 can restrict the rotating seat 33 from moving up and down freely and can prevent the rotating seat 33 from tilting during use. The locking block 44 is L-shaped and the edge of the moving plate 41 is arc-shaped. The arc design makes it less likely for the operator to be injured during use.

[0031] Working principle: When the whole device is in operation, the positioning sleeve 1 needs to be placed in the working position first. Then, the neuroendoscope can be inserted into the buckle 2. Then, the moving plate 41 can be moved to move the neuroendoscope. When it is moved to the working position, the moving plate 41 can be pressed to move both ends of the moving plate 41 inward. The inward movement of the two ends of the moving plate 41 will cause the locking block 44 and the positioning block 43 to move closer to each other. Then, the locking block 44 and the positioning block 43 can be inserted into the slot 46. At this time, the moving plate 41 can be released. The moving plate 41 will recover under its own elastic deformation. This will cause the locking block 44 to be locked into the slot 47. At this time, the moving plate 41 will be fixed and cannot move. At the same time, the neuroendoscope will also be fixed.

[0032] After the neuroendoscopy is fixed, its position needs to be fine-tuned. This can be done by moving the latch 2. The latch 2 is rotatably connected to the guide plate 48 through the connecting component 3. When the latch 2 is moved, it will rotate around the rotating shaft 32. A rubber sleeve 35 is fixed on the outer wall of the rotating shaft 32. The inner wall of the rotating seat 33 is provided with a matching receiving groove 34. When the operator stops moving the latch 2, the rubber sleeve 35 will squeeze the inner wall of the rotating seat 33 to generate friction. This friction can prevent the latch 2 from rotating randomly, so that the neuroendoscopy can be stably maintained in the new position after fine-tuning, meeting the doctor's needs for fine-tuning the fixation position.

[0033] 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.
