Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a device for assisting in adjusting posture during intraventricular endoscopic surgery. Background Technology

[0002] In endoscopic surgery, once the endoscope is adjusted in angle and displacement, it needs to be held in that position. During surgery, this is usually achieved by the surgeon holding it or using a bedside support. Holding it by the surgeon can interfere with the procedure, often requiring an assistant to operate under the endoscope, but assistants often struggle to coordinate effectively with the surgeon. Using a support, which consists of multiple segments with joints, requires adjusting and fixing each joint individually, making it very cumbersome. Because it's positioned next to the operating table, it's easily bumped during surgery, causing the endoscope's position or angle to shift. Summary of the Invention

[0003] The purpose of this invention is to provide a device for assisting in adjusting the posture during intravenous endoscopic surgery, so as to solve the problems existing in the prior art. It is easy to adjust and does not occupy the space next to the bed, reducing the probability of the endoscope being unintentionally touched and changing its posture during surgery.

[0004] To achieve the above objectives, the present invention provides the following solution:

[0005] The present invention provides a device for assisting in adjusting posture during intraventricular endoscopic surgery, comprising a base, a flexible component, and a locking assembly;

[0006] The base is used to fix it to the skull of the subject by screws. The base has a first through hole in the middle, which corresponds to a bone window opened on the skull of the subject.

[0007] The lower end of the flexible member is detachably mounted on the base, and the upper end is detachably connected to the locking assembly. The locking assembly is used to lock the endoscopic endoscope. The flexible member includes a flexible tube, the inner cavity of which communicates with the first through hole. In its natural state, the flexible tube can maintain the locked endoscopic endoscope in a fixed posture. Under a certain force, the flexible tube can bend to change the posture of the locked endoscopic endoscope.

[0008] Preferably, the locking assembly includes a fixed sleeve, grippers, and a locking ring. The fixed sleeve has a plurality of sliding grooves evenly distributed circumferentially, inclined inwards from top to bottom. These sliding grooves communicate inwardly with the inner hole of the fixed sleeve, which in turn communicates with the inner cavity of the flexible tube. Each of the sliding grooves has a gripper slidably connected to it. The grippers are evenly distributed circumferentially, and their outer surfaces are located within the same conical surface. Each gripper has an external conical thread on its outer surface, and its inner bottom has a clamping part for clamping the endoscopic endoscope. The locking ring is rotatably sleeved around the fixed sleeve and axially fixed relative to it. The inner wall of the locking ring has an internal conical thread that engages with the external conical thread.

[0009] Preferably, the clamping part includes a clamping surface extending along the axial direction of the fixing sleeve, and the clamping surface is a plane or an arc surface; when the clamping surface is an arc surface, its radius is equal to the radius of the endoscopic endoscope.

[0010] Preferably, the locking assembly further includes a protective cover, which is threaded to the upper end of the fixing sleeve, and the protective cover has a through hole in the middle that communicates with the inner hole of the fixing sleeve.

[0011] Preferably, the base includes a disc and a fixing ring. The fixing ring is fixed to the upper surface of the disc and is coaxial with the disc. The outer circumferential surface of the fixing ring is provided with an external thread. The lower end of the flexible tube is fixed with a lower mounting ring. The inner circumferential surface of the lower mounting ring is provided with an internal thread for threaded connection with the fixing ring. The edge of the disc is provided with a plurality of screw mounting holes. Screws are fixed to the skull of the subject through the screw mounting holes. The center of the disc is provided with a through hole with the same inner diameter as the fixing ring.

[0012] Preferably, the lower surface of the disk is a concave curved surface to correspond to the shape of the physiological curvature of the skull.

[0013] Preferably, the upper end of the flexible tube is fixedly provided with an upper mounting ring, the inner circumferential surface of the upper mounting ring is provided with an internal thread, and the lower end of the fixed sleeve is provided with an external thread for threaded connection with the upper mounting ring.

[0014] Preferably, a rubber pad is provided on the clamping surface.

[0015] Preferably, the flexible tube is a cylindrical tube; or the diameter of the flexible tube gradually increases from top to bottom.

[0016] Preferably, the outer peripheral surface of the locking ring is provided with patterned protrusions.

[0017] The present invention achieves the following technical effects compared to the prior art:

[0018] This invention provides a device for assisting in adjusting the posture during endoscopic ventriculoscopy. A base is fixed to the subject's skull with screws, aligning a first through-hole in the center of the base with a bone window on the subject's skull. The lower end of a flexible component is then installed on the base, and a locking assembly is installed on the upper end of the flexible component. The endoscopic endoscope is then locked in place using the locking assembly. When the posture of the endoscopic endoscope needs adjustment, a force is applied to the flexible tube, causing it to bend. Once the endoscopic endoscope is adjusted to the desired posture, the force is stopped. The flexible tube maintains the current posture of the endoscopic endoscope. Adjustment is convenient and quick, does not occupy bedside space, and reduces the likelihood of the endoscope being unintentionally bumped and altered during surgery. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] The purpose of this invention is to provide a device for assisting in adjusting the posture during intravenous endoscopic surgery, in order to solve the problems existing in the prior art. It is easy to adjust and does not occupy the space next to the bed, reducing the probability that the endoscope will be unintentionally touched and change its posture during the operation.

[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] like Figures 1-7 As shown, this embodiment provides a device for assisting in adjusting posture during intraventricular endoscopic surgery, including a base 1, a flexible member 2, and a locking assembly 3;

[0032] The base 1 is used to fix it to the skull of the subject by screws. The middle part of the base 1 is provided with a first through hole 4, which corresponds to the bone window opened on the skull of the subject.

[0033] The lower end of the flexible member 2 is detachably mounted on the base 1, and the upper end is detachably connected to the locking assembly 3. The locking assembly 3 is used to lock the endoscopic endoscope. The flexible member 2 includes a flexible tube 5. The inner cavity of the flexible tube 5 is connected to the first through hole 4. The flexible tube 5 can maintain the posture of the locked endoscopic endoscope in its natural state. The flexible tube 5 can bend under a certain force to change the posture of the locked endoscopic endoscope.

[0034] In use, the base 1 is fixed to the subject's skull with screws, so that the first through hole 4 in the middle of the base 1 corresponds to the bone window opened on the subject's skull. Then, the lower end of the flexible member 2 is installed on the base 1, and the locking component 3 is installed on the upper end of the flexible member 2. Then, the endoscopic endoscope is locked by the locking component 3. When it is necessary to adjust the posture of the endoscopic endoscope, a force is applied to the flexible tube 5 to bend the flexible tube 5. After adjusting the endoscopic endoscope to the required posture, the force is stopped. The endoscopic endoscope is kept in the current posture by the flexible tube 5. The adjustment is convenient and quick, does not occupy the space next to the bed, and reduces the chance of the endoscope being unintentionally touched and changing its posture during surgery.

[0035] In this embodiment, the locking assembly 3 includes a fixing sleeve 6, grippers 7, and a locking ring 8. The fixing sleeve 6 has multiple sliding grooves 9 evenly arranged circumferentially, inclined inwards from top to bottom. Preferably, there are three sliding grooves 9. The sliding grooves 9 communicate inwardly with the inner hole of the fixing sleeve 6, which in turn communicates with the inner cavity of the flexible tube 5. Each sliding groove 9 has a gripper 7 slidably connected to it. The grippers 7 are evenly distributed circumferentially, and their outer surfaces are located within the same conical surface. Each gripper 7 has an external conical thread 10 on its outer surface and a clamping part 11 for clamping a ventriculoscope on its inner bottom. The locking ring 8 is rotatably sleeved around the fixing sleeve 6 and axially fixed relative to it. The inner wall of the locking ring 8 has an internal conical thread 12 that engages with the external conical thread 10. By rotating the locking ring 8, the grippers 7 can slide along the sliding grooves 9 under the action of the internal conical thread 12 and the external conical thread 10. When the locking ring 8 is rotated clockwise, the gripper 7 slides obliquely downward along the sliding groove 9, and the clamping parts 11 move closer to each other, thereby clamping and fixing the endoscopic endoscope. When the locking ring 8 is rotated counterclockwise, the gripper 7 slides obliquely upward along the sliding groove 9, and the clamping parts 11 move away from each other, releasing the endoscopic endoscope. The operation is convenient and quick.

[0036] In this embodiment, the clamping part 11 includes a clamping surface 13 extending along the axial direction of the fixing sleeve 6. The clamping surface 13 is a plane. The endoscopic endoscope is clamped by the three clamping surfaces 13 approaching each other and released by the three clamping surfaces 13 moving away from each other. In other embodiments, the clamping surface 13 can also be an arc surface. When the clamping surface 13 is an arc surface, its radius is equal to the radius of the endoscopic endoscope. When the three clamping surfaces 13 approach each other to clamp the endoscopic endoscope, each arc surface is in close contact with the outer peripheral surface of the endoscopic endoscope, resulting in a better clamping effect.

[0037] In this embodiment, the locking assembly 3 further includes a protective cover 14, which is threadedly connected to the upper end of the fixing sleeve 6. The protective cover 14 has a through hole in the middle that communicates with the inner hole of the fixing sleeve 6. The protective cover 14 protects each clamping jaw 7, preventing impurities from entering the threaded connection between the clamping jaw 7 and the locking ring 8 and affecting the transmission process.

[0038] In this embodiment, the base 1 includes a disc 15 and a fixing ring 16. The fixing ring 16 is fixed to the upper surface of the disc 15 and is coaxial with the disc 15. The outer circumferential surface of the fixing ring 16 is provided with external threads. The lower end of the flexible tube 5 is fixed with a lower mounting ring 17. The inner circumferential surface of the lower mounting ring 17 is provided with internal threads for threaded connection with the fixing ring 16. The edge of the disc 15 is provided with a plurality of screw mounting holes 18, preferably four, which are evenly distributed circumferentially. Screws are fixed to the skull of the subject through the screw mounting holes 18. The center of the disc 15 is provided with a through hole with the same inner diameter as the fixing ring 16. The base 1 and the flexible tube 5 are connected by internal and external threads, which facilitates disassembly and assembly. By providing screw mounting holes 18, it is easy to fix the base 1 to the skull of the subject with screws.

[0039] In this embodiment, the lower surface of the disc 15 is a concave curved surface to correspond to the shape of the physiological curvature of the skull, so that the lower surface of the disc 15 fits more closely with the skull around the bone window and the installation is more stable.

[0040] In this embodiment, an upper mounting ring 19 is fixedly provided at the upper end of the flexible tube 5. The inner circumferential surface of the upper mounting ring 19 is provided with an internal thread, and the outer circumferential surface of the lower end of the fixing sleeve 6 is provided with an external thread for threaded connection with the upper mounting ring 19. The flexible tube 5 and the fixing sleeve 6 are connected by an internal and external thread connection, which facilitates disassembly and assembly.

[0041] In this embodiment, a rubber pad (not shown in the figure) is provided on the clamping surface 13 to increase the contact area with the outer periphery of the endoscopic endoscope, disperse the pressure of the clamping claw 7 on the endoscopic endoscope, and avoid damaging the endoscopic endoscope.

[0042] In this embodiment, the flexible tube 5 is a cylindrical tube. In other embodiments, the flexible tube 5 can also be configured as a tube structure with its diameter gradually increasing from top to bottom, which can increase the adjustable range of the ventriculoscope.

[0043] In this embodiment, the outer peripheral surface of the locking ring 8 is provided with patterned protrusions 20 to increase the friction with the hand and facilitate the rotation of the locking ring 8.

[0044] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
