Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an anti-slip locking structure for a neurosurgical head frame. Background Technology

[0002] A neurosurgical head frame is a surgical device used in conjunction with craniocerebral surgery. It is an essential fixation instrument in neurosurgery. When using a neurosurgical head frame, head pins typically need to pierce the scalp and embed into the outer table of the skull to fix the patient's head. This fixation method provides reliable stability, ensuring that the head remains still during surgery. The head frame is mostly installed using a support structure based on the operating table frame.

[0003] The current installation method mostly involves using two half-shaft sleeves, which are fitted onto the crossbar between the legs of the operating table and fastened together with bolts. The installation is done by clamping, and the tightness relies entirely on friction. This installation base supports the entire equipment frame, head frame, and the patient's own weight. When the weight is too great and exceeds the friction, the sleeves are prone to rotation and slippage, resulting in unstable support. The resulting vibration may cause secondary damage to the head pins and affect the normal operation of the surgery. Utility Model Content

[0035] Compared with the prior art, the beneficial effects of this utility model are:

[0036] 1. Connect the two clip-on semi-rings to the connecting rod between the two legs of the operating table head, and fix them together. Then, attach the outer rotating sleeve to the outer surface of the clip-on semi-rings. Pull the first telescopic rod out of the first sleeve to a suitable length, and rotate the outer rotating sleeve on the outer surface of the clip-on semi-rings to adjust it to a suitable angle so that the abutment claws can abut against the side surfaces of the two legs of the operating table head. Install other support structures at the vertical bar at the front end of the T-shaped rod, and connect the head frame already installed at the patient's head to the support structure to support the patient's head. Conversely, the patient's own weight is used to press down on the support structure and, using the lever principle, force the two abutment claws to abut tightly against the operating table legs. This prevents the installation base where the surgical head frame is connected to the hospital bed from sliding and vibrating, which could cause secondary injury to the patient and affect the operation. This provides a certain anti-slip locking and safety effect.

[0037] 2. After the overall structure is installed, adjust the angle of the No. 2 sleeve through the hinge joint at the lower end of the T-shaped rod vertical rod, and then pull the No. 2 telescopic rod out to a suitable length so that the foot pad is against the ward floor, providing auxiliary support for the head frame and support structure, and further ensuring the stability of the overall structure.

[0044] 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.

[0045] Please see Figures 1-5 In this embodiment of the present invention, a neurosurgical head frame anti-slip locking structure includes an outer rotating sleeve 1, an inner clip 2, and an anti-slip bracket 3. The inner clip 2 includes two clip semi-rings 201. The outer rotating sleeve 1 is rotatably sleeved on the outer surface of the clip semi-rings 201. The anti-slip bracket 3 includes a first sleeve 301, which is fixedly installed on the upper surface of the outer rotating sleeve 1. A first telescopic rod 302 is slidably sleeved at both ends of the first sleeve 301. A stop hook 303 is fixedly installed at one end of the first telescopic rod 302. A T-shaped rod 304 is fixedly installed on the front side of the middle part of the first sleeve 301.

[0046] Specifically, two clip-on semi-rings 201 are fitted onto the connecting rod between the two legs of the operating table head, and then fixed together. Next, the outer rotating sleeve 1 is fitted onto the outer surface of the clip-on semi-rings 201. The first telescopic rod 302 is pulled out of the first sleeve 301 to a suitable length, and the outer rotating sleeve 1 is rotated on the outer surface of the clip-on semi-rings 201 to adjust to a suitable angle, so that the abutment claws 303 can abut against the side surfaces of the two legs of the operating table head. Other support structures are installed at the front vertical bar of the T-shaped rod 304, and the head frame already installed at the patient's head is connected to the support structures to support the patient's head. Conversely, the patient's own weight is used to press down on the support structures, and the lever principle is used to force the two abutment claws 303 to tightly abut against the operating table legs, preventing slippage and vibration at the installation base where the surgical head frame connects to the bed, thus avoiding secondary injury to the patient from the head pins and affecting the surgery, and providing a certain anti-slip locking safety effect.

[0047] Example 1

[0048] like Figures 2-4 As shown, in this embodiment, the outer rotating sleeve 1 includes a first outer half-ring 101, a second outer half-ring 102, a hinge shaft 103, a first fastening screw 104, a base rod 105, a retaining strip storage seat 106, a connecting plate 107, a pull rod 108, a limiting retaining strip 109, and a return spring 110. The first outer half-ring 101 is sleeved on the outer surface of the clamping half-ring 201; the second outer half-ring 102 is sleeved on the outer surface of the clamping half-ring 201; the hinge shaft 103 is fixedly installed on one edge of the first outer half-ring 101 and the second outer half-ring 102; the first fastening screw... Plate 104 is fixedly installed on the other edge of the first outer half ring 101 and the second outer half ring 102; base rod 105 is fixedly installed on the upper surface of the first outer half ring 101, and the upper end of base rod 105 is fixedly connected to the middle of the first sleeve 301; clip storage seat 106 is fixedly installed on the bottom of the second outer half ring 102; connecting plate 107 slides through clip storage seat 106; pull rod 108 is fixedly installed on the bottom side of connecting plate 107; limiting clip 109 is fixedly installed on the upper side of connecting plate 107; return spring 110 is embedded at both ends of the bottom of limiting clip 109.

[0049] In this embodiment, the outer rotating sleeve 1 is configured as an openable and closable clamp structure, so that the first outer half-ring 101 and the second outer half-ring 102 can be freely fitted onto the outer surface of the clamp half-ring 201. After installation, the lengths of the two first telescopic rods 302 are adjusted, and the pull rod 108 is pulled to allow the limiting clip 109 to retract into the clip storage seat 106 and be unlocked. The outer rotating sleeve 1 is rotated to adjust the angle of the base rod 105, so that the abutment claw 303 abuts against the bed leg. After adjustment, the pull rod 108 is released and the return spring 110 is used to allow the limiting clip 109 to engage in the limiting ratchet 202 for locking.

[0050] likeFigure 4 As shown, in this embodiment, the inner sleeve 2 further includes a limiting ratchet 202, a positioning snap-fit ​​203, a second fastening screw 204, and a fastening washer 205. The limiting ratchet 202 is fixedly installed on the outer surface of the sleeve half-ring 201, and the limiting ratchet 202 is engaged with the limiting snap-fit ​​strip 109. The positioning snap-fit ​​203 is provided on both sides of the joint of the two sleeve half-rings 201. The second fastening screw 204 is fixedly installed on both sides of the sleeve half-ring 201. The fastening washer 205 is fixedly installed on the inner surface of the sleeve half-ring 201.

[0051] In practice, the inner sleeve 2 is consistent with the traditional surgical head frame installation base and is installed on the operating table crossbar in a sleeve manner. The fastening pad 205 is used to increase friction and prevent slippage. Although it has the ability to be disassembled, it can be directly welded to the operating table crossbar in actual use, completely avoiding the possibility of slippage. The first outer half ring 101 and the second outer half ring 102 continue to maintain the detachability of the head frame installation frame structure.

[0052] Example 2

[0053] Based on Embodiment 1, in order to compensate for the possibility that the crossbar of T-shaped rod 304 may be bent under long-term use, since it relies entirely on the suspended T-shaped rod 304 to support other support structures, surgical head frame body and patient self-weight.

[0054] like Figure 1 , 5 As shown, in this embodiment, the anti-slip bracket 3 further includes a hinge joint 305, a second sleeve 306, a second telescopic rod 307, a foot pad 308, locking holes 309, and a locking pin 310. The hinge joint 305 is fixedly installed at both ends of the vertical rod of the T-shaped rod 304; the second sleeve 306 is hinged to the lower end of the vertical rod of the T-shaped rod 304 through the hinge joint 305; the second telescopic rod 307 is slidably sleeved on the lower end of the second sleeve 306; the foot pad 308 is fixedly installed at the lower end of the second telescopic rod 307; the locking holes 309 are evenly spaced on the upper surface of the first sleeve 301 and one side surface of the second sleeve 306; and the locking pin 310 is embedded in the upper surface of the first telescopic rod 302 and one side surface of the second telescopic rod 307.

[0055] In practice, after the overall structure is installed, the angle of the second sleeve 306 is adjusted by the hinge joint 305 at the lower end of the T-shaped rod 304, and then the second telescopic rod 307 is pulled out to a suitable length so that the foot pad 308 is against the ward floor, providing auxiliary support for the head frame and support structure, and further ensuring the stability of the overall structure.

[0056] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0057] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution.
