It is used in conjunction with an intraoperative image navigation system to achieve precise registration between surgical instruments and target anatomical structures. The main purpose of this reference frame is to provide a stable reference point during the operation, enabling the surgeon to accurately position the surgical instruments.

[0003] Chinese Patent Publication No. CN212346717U, published on 20210115, discloses an automatic registration reference frame for neurosurgical navigation surgery, comprising a reference frame assembly and a reference frame base assembly. The reference frame assembly includes a reference frame body; the reference frame base assembly includes a reference frame base, at least one positioning device is provided in the middle of the reference frame body, and at least one reflective ball mounting seat is provided on the outer ring of the positioning device, with reflective balls provided on the reflective ball mounting seat; the positioning device is connected to one end face of the reference frame base; several positioning balls are provided on the other end face of the reference frame base and are then adhered to the patient's head by double-sided foam tape.

[0004] In existing automatic registration reference frames for neurosurgical navigation surgery, the top mount is directly fixed to the top of the base via a locking rod. During implementation, due to the extension of the connecting frame, it is prone to axial stress, which can cause the locking rod to loosen. Therefore, there is an urgent need to propose a corresponding automatic registration reference frame for neurosurgical navigation surgery to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an automatic registration reference frame for neurosurgical navigation surgery in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automated registration reference frame for neurosurgical navigation includes a base, a rotating seat on the base, a top seat fixedly connected to the top of the rotating seat via a locking rod, and a limiting component for limiting the axial deflection of the top seat between the top seat and the rotating seat. A connecting frame is fixedly connected to the outer wall of the top seat, and a reflective ball is fixedly connected to the top of the open end of the connecting frame.

[0008] Preferably, the outer side of the rotating seat is fitted with a fixing sleeve that is fixedly connected to the top of the base, and the outer side of the fixing sleeve is provided with a positioning part for axial positioning of the rotating seat.

[0009] Preferably, the rotating seat has a T-shaped cross-section.

[0010] Preferably, the positioning part includes a positioning rod that is screwed into the outer wall of the fixed sleeve, and the open end of the positioning rod abuts against the outer wall of the rotating seat.

[0011] Preferably, the limiting component includes a rectangular block fixedly connected to the bottom of the top seat, the outer wall of the rectangular block being inserted into the top of the rotating seat through a slot, and the top seat, the rectangular block, and the inner wall of the rotating seat being screwed together.

[0012] Preferably, the bottom of the top seat is integrally formed with the rectangular block.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. In this application, the rectangular block at the bottom of the top seat is combined with the slot at the top of the rotating seat. The top seat, the rectangular block and the inner wall of the rotating seat are simultaneously screwed together by the locking rod, thereby fixing the top seat and the rotating seat and installing the top seat and the reflective ball. While ensuring that the top seat is easy to install and remove, the cooperation between the rectangular block and the slot can limit the axial movement tendency of the top seat to avoid the locking rod from loosening, thereby improving the stability of the automatic registration reference frame used in neurosurgical navigation surgery.

[0015] 2. In this application, the positioning rod is rotated to separate its open end from the outer wall of the rotating seat, and the connecting frame is moved. The connecting frame will move in conjunction with the rotating seat to deflect axially. The T-shaped rotating seat can ensure the stability of the vertical position of the rotating seat until the connecting frame deflects to a suitable angle. Then, the positioning rod is rotated to reconnect its open end with the outer wall of the rotating seat to lock the position of the rotating seat and the connecting frame. This allows the axial position of the connecting frame and the reflector ball to be easily adjusted according to the usage requirements. Attached Figure Description

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] An automatic registration reference frame for neurosurgical navigation surgery includes a base 1, a rotating seat 10 on the base 1, a top seat 4 fixedly connected to the top of the rotating seat 10 by a locking rod 5, and a limiting component for limiting the axial deflection of the top seat 4 between the top seat 4 and the rotating seat 10. A connecting frame 2 is fixedly connected to the outer wall of the top seat 4, and a reflective ball 3 is fixedly connected to the top of the open end of the connecting frame 2.

[0025] The rectangular block 8 at the bottom of the top seat 4 is combined with the slot 9 at the top of the rotating seat 10. The top seat 4, the rectangular block 8 and the inner wall of the rotating seat 10 are simultaneously screwed together by the locking rod 5, thereby fixing the top seat 4 and the rotating seat 10. This allows the top seat 4 to be installed with the reflective ball 3. While ensuring that the top seat 4 is easy to install and remove, the cooperation between the rectangular block 8 and the slot 9 can limit the axial movement tendency of the top seat 4 to prevent the locking rod 5 from loosening, thereby improving the stability of the automatic registration reference frame used in neurosurgical navigation surgery.

[0026] It should be noted that the main body, consisting of base 1, top seat 4, connecting frame 2 and reflective ball 3, uses existing technology, and the auxiliary registration mechanism of the reference frame in neurosurgical navigation surgery will not be described in detail here.

[0027] Specifically, such as Figure 2 and Figure 4As shown, a fixed sleeve 6 is fitted on the outer side of the rotating seat 10 and fixedly connected to the top of the base 1. A positioning part for axial positioning of the rotating seat 10 is provided on the outer side of the fixed sleeve 6. The rotating seat 10 has a T-shaped cross-section. The positioning part includes a positioning rod 7 that is screwed into the outer wall of the fixed sleeve 6. The open end of the positioning rod 7 abuts against the outer wall of the rotating seat 10. Rotating the positioning rod 7 separates its open end from the outer wall of the rotating seat 10. The connecting frame 2 is moved, and the connecting frame 2 will move the rotating seat 10 axially. The T-shaped rotating seat 10 can ensure the stability of the vertical position of the rotating seat 10 until the connecting frame 2 is deflected to a suitable angle. The positioning rod 7 is then rotated so that its open end re-engages with the outer wall of the rotating seat 10 to lock the position of the rotating seat 10 and the connecting frame 2. This allows the axial position of the connecting frame 2 and the reflective ball 3 to be easily adjusted according to usage requirements.

[0028] Specifically, such as Figure 2 and Figure 3 As shown, the limiting component includes a rectangular block 8 fixedly connected to the bottom of the top seat 4. The outer wall of the rectangular block 8 is inserted into the top of the rotating seat 10 through a slot 9, and the top seat 4, the rectangular block 8 and the inner wall of the rotating seat 10 are screwed together. The bottom of the top seat 4 and the rectangular block 8 are integrally formed. The axial movement tendency of the top seat 4 can be restricted by the cooperation between the rectangular block 8 and the slot 9 to prevent the locking rod 5 from becoming loose.

[0029] Working principle: The rectangular block 8 at the bottom of the top seat 4 is combined with the slot 9 at the top of the rotating seat 10. The top seat 4, the rectangular block 8 and the inner wall of the rotating seat 10 are simultaneously screwed together by the locking rod 5, thereby fixing the top seat 4 and the rotating seat 10, and thus installing the top seat 4 and the reflector ball 3. While ensuring that the top seat 4 is easy to install and remove, the cooperation between the rectangular block 8 and the slot 9 can limit the axial movement tendency of the top seat 4 to prevent the locking rod 5 from loosening, thereby improving the stability of the automatic registration reference frame used in neurosurgical navigation surgery. Rotating the positioning rod 7 separates its open end from the outer wall of the rotating seat 10. Moving the connecting frame 2 will cause the rotating seat 10 to deflect axially. The T-shaped structure of the rotating seat 10 can ensure the stability of the vertical position of the rotating seat 10 until the connecting frame 2 deflects to the appropriate angle. Rotating the positioning rod 7 again makes its open end re-engage with the outer wall of the rotating seat 10 to lock the position of the rotating seat 10 and the connecting frame 2, so that the axial position of the connecting frame 2 and the reflector ball 3 can be easily adjusted according to the usage requirements.

[0030] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
