Description

Technical Field

[0001] This utility model relates to the field of neurosurgical temporalis muscle suturing technology, specifically to a neurosurgical temporalis muscle suturing and fixation device. Background Technology

[0002] Many intracranial neurosurgical procedures require the temporalis muscle to be dislocated to expose the skull, allowing for further craniotomy. The procedure involves: exposing the temporalis muscle; incising the temporalis muscle; detaching the temporalis muscle from the skull to expose it, leaving a small amount of temporalis muscle on the skull; after the intracranial surgery, PEEK craniotomy material is used to repair the hole in the skull. Once the PEEK craniotomy material is fixed, fixing the temporalis muscle is more difficult. Sutures are usually used to fix it to the subcutaneous tissue layer distal to the temporalis muscle, or the detached temporalis muscle is sutured to the small amount of temporalis muscle left on the skull during craniotomy.

[0003] This method of treating the temporalis muscle has certain drawbacks:

[0004] 1) The temporalis muscle was cut open, resulting in severe damage to the temporalis muscle;

[0005] 2) Due to poor fixation of the temporalis muscle, patients may experience temporalis muscle atrophy several months after surgery, which manifests as a depression in the surgical area compared to the normal side, thus affecting the patient's appearance and causing psychological stress.

[0006] Therefore, it is extremely important to effectively fix the temporalis muscle and avoid postoperative temporalis muscle atrophy. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a neurosurgical temporalis muscle suture fixation device to overcome the shortcomings of the prior art.

[0008] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0009] A neurosurgical temporalis muscle suture fixation device includes: a screw with at least one suture attached to it, and the other end of each suture connected to a suture needle.

[0010] The beneficial effects of this utility model are:

[0011] The procedure for suturing the temporalis muscle using this device in neurosurgery is as follows: First, the screw is directly fixed to the skull; the needle holder with the suture needle is used to suture the temporalis muscle, and the suture needle is removed; then the thread on one side of the screw and the thread on the other side of the temporalis muscle are tied together.

[0012] This device can effectively fix the temporalis muscle after incision in neurosurgery, so as to avoid poor fixation of the temporalis muscle, avoid postoperative temporalis muscle atrophy, and avoid the psychological pressure caused to the patient by the unsightly appearance caused by unilateral muscle atrophy. The design is simple and practical and can be promoted for use in various intracranial surgeries.

[0013] Based on the above technical solution, the present invention can be further improved as follows.

[0014] Furthermore, two sutures are connected to the screw.

[0015] The further beneficial effect of adopting the above method is that the temporalis muscle can be sutured in two different directions.

[0016] Furthermore, a ring is fitted onto the screw, the inner diameter of which is smaller than the diameter of the screw head. One end of each suture is connected to the ring fitted onto the screw, and the other end is connected to a suture needle.

[0017] The further beneficial effects of adopting the above are: on the one hand, the direction of the suture can be adjusted, and on the other hand, the threads on the screw can be prevented from cutting the suture.

[0018] Furthermore, the ring is provided with at least one connecting structure for securing the suture.

[0019] Furthermore, the connecting structure is a clamping tube that deforms under external force to clamp one end of the suture inside.

[0020] The further beneficial effect of adopting the above method is that the ring and the suture can be fixedly connected very easily.

[0021] Furthermore, it also includes: a PEEK plate that matches the contour of the hole to be repaired in the skull, with multiple fluid holes opened on the PEEK plate, and a screw screwed into one of the fluid holes on the PEEK plate.

[0022] The further beneficial effects of adopting the above are as follows:

[0023] The procedure for suturing the temporalis muscle using this device in neurosurgery is as follows:

[0024] Since the PEEK plate matches the contour of the hole to be repaired in the skull, the PEEK plate is fixed to the skull with nails to seal the hole to be repaired in the skull.

[0025] The temporalis muscle is sutured using a needle holder with a suture needle, and the suture needle is then removed.

[0026] Simply tie the thread on one side of the screw to the thread on the other side of the temporalis muscle;

[0027] This method eliminates the need to fix screws to the skull. Instead, screws are fixed to a PEEK plate that seals the hole to be repaired in the skull. The screws are connected to the PEEK plate by utilizing the existing fluid holes on the plate. This reduces the need to fix screws to the skull, thus minimizing damage to the body. The method achieves skull repair while simultaneously fixing the temporalis muscle after incision.

[0028] Furthermore, the inner wall of the liquid hole on the PEEK plate for engaging with the screw is provided with internal threads.

[0029] The further beneficial effect of adopting the above is that it makes it easier to connect the screw to the liquid hole on the PEEK plate. Attached Figure Description

[0037] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0038] Example 1

[0039] like Figure 1 , Figure 2 As shown, a neurosurgical temporalis muscle suture fixation device includes: a screw 1, preferably made of a material harmless to the human body, such as titanium, i.e., the screw 1 is a titanium screw; at least one suture 2 is connected to the screw 1, preferably an absorbable suture; and the other end of each suture 2 is connected to a suture needle 3.

[0040] The procedure for suturing the temporalis muscle using this device during neurosurgery is as follows:

[0041] First, fix screw 1 directly to the skull;

[0042] The needle holder with suture needle 3 is used to suture the temporalis muscle, and then suture needle 3 is removed.

[0043] Simply tie the thread on one side of screw 1 to the thread on the other side of the temporalis muscle;

[0044] This device can effectively fix the temporalis muscle after incision in neurosurgery, so as to avoid poor fixation of the temporalis muscle, avoid postoperative temporalis muscle atrophy, and avoid the psychological pressure caused to the patient by the unsightly appearance caused by unilateral muscle atrophy. The design is simple and practical and can be promoted for use in various intracranial surgeries.

[0045] Example 2

[0046] like Figure 2 As shown, this embodiment is a further improvement on embodiment 1, as detailed below:

[0047] Two sutures 2 are connected to the screw 1, and the other end of each suture 2 is connected to a suture needle 3. At this time, the neurosurgical temporalis muscle suture fixation device can suture the temporalis muscle in two different directions.

[0048] Example 3

[0049] like Figure 1 , Figure 2 As shown, this embodiment is a further improvement on embodiment 1, as detailed below:

[0050] A ring 4 is fitted onto the screw 1. The ring 4 is preferably made of a harmless material, such as titanium, meaning the ring 4 is a titanium ring. The inner diameter of the ring 4 is larger than the outer diameter of the screw shank end, ensuring the ring 4 fits onto the screw 1. However, the inner diameter of the ring 4 is smaller than the diameter of the screw cap end, preventing the ring 4 from detaching from the screw 1 when it is fixed to the skull. One end of each suture 2 is connected to the ring 4 fitted onto the screw 1, and the other end of each suture 2 is connected to a suture needle 3. By fitting a ring 4 onto the screw 1 and connecting the suture 2 to the ring 4, the direction of the suture 2 can be adjusted. This can prevent the threads on screw 1 from cutting the suture 2. Of course, in practical applications, it is not ruled out that the ring 4 is not designed. Instead, one end of the suture 2 forms a loop, and the suture 2 is placed on the screw 1 by relying on the loop. Alternatively, a through hole can be drilled on the screw 1 near the nut, and one end of the suture 2 can be passed through the through hole on the screw 1 first, and then its end can be connected to the suture 2 to form a loop. Or, a through hole can be drilled on the nut of screw 1, and one end of the suture 2 can be passed through the through hole on the nut of screw 1 first, and then its end can be connected to the suture 2 to form a loop.

[0051] Example 4

[0052] like Figure 1 , Figure 2 , Figure 3 As shown, this embodiment is a further improvement on embodiment 1, 2, or 3, as detailed below:

[0053] The ring 4 is provided with at least one connecting structure 5 for fixing the suture 2. The suture 2 is fixed to the ring 4 through the connecting structure 5 to ensure safety. The connecting structure 5 can be located on the upper surface of the ring 4, the lower surface of the ring 4, or the circumferential surface of the ring 4. Preferably, the connecting structure 5 is located on the circumferential surface of the ring 4, and the outer diameter of the ring 4 is smaller than the outer diameter of the nut of the screw 1. In this case, the ring 4 can be hidden under the nut of the screw 1. At the same time, the connecting structure 5 is also preferably not extended beyond the nut of the screw 1, so that the connecting structure 5 can also be hidden. Of course, in actual application, it is not excluded that a hole is drilled in the ring 4, one end of the suture 2 is passed through the hole in the ring 4 and then tied, or one end of the suture 2 is first wrapped around the inner ring 4 and then its end is connected to the suture 2 to form a loop.

[0054] Furthermore: the connecting structure 5 is a clamping tube that deforms under external force to clamp one end of the suture 2 inside it. This structure is similar to the connection method between the suture 2 and the suture needle 3. Since this method is quite common, its principle will not be described in detail here.

[0055] Example 5

[0056] like Figure 4 , Figure 5 As shown, this embodiment is a further improvement on any one of embodiments 1 to 4, as detailed below:

[0057] The neurosurgical temporalis muscle suture fixation device also includes: a PEEK plate 6 that matches the contour of the hole to be repaired in the skull, the PEEK plate 6 having multiple fluid holes 610, and a screw 1 screwed into one of the fluid holes 610 on the PEEK plate 6. Figure 4 and Figure 5 This is merely an illustrative representation of the connection between screw 1 and PEEK plate 6, and does not imply that screw 1 can only be fixed at this location on PEEK plate 6. It can be fixed in any of the liquid holes 610 on PEEK plate 6. The processed shape of PEEK plate 6 varies with the outline shape of the hole to be repaired in the skull and is not fixed. Similarly, the distribution of liquid holes 610 on PEEK plate 6 also varies with the shape of PEEK plate 6.

[0058] The procedure for suturing the temporalis muscle using this device in neurosurgery is as follows:

[0059] Since the PEEK plate 6 matches the outline of the hole to be repaired in the skull, the PEEK plate 6 is fixed to the skull with nails to seal the hole to be repaired in the skull.

[0060] The needle holder with suture needle 3 is used to suture the temporalis muscle, and then suture needle 3 is removed.

[0061] Simply tie the thread on one side of screw 1 to the thread on the other side of the temporalis muscle;

[0062] This method eliminates the need to fix the screw 1 to the skull. Instead, it fixes it to the PEEK plate 6 that seals the hole to be repaired in the skull. The screw 1 is connected to the PEEK plate 6 by using the existing fluid holes 610 on the PEEK plate 6. This reduces the need to fix the screw 1 to the skull, thereby reducing damage to the human body. The method achieves skull repair while simultaneously fixing the temporalis muscle after incision.

[0063] Example 6

[0064] like Figure 4 , Figure 5 As shown, this embodiment is a further improvement on embodiment 5, as detailed below:

[0065] The inner wall of the liquid hole 610 on the PEEK plate 6, which is used to engage with the screw 1, is provided with internal threads (not shown in the figure), which makes it easier to connect the screw 1 to the liquid hole 610 on the PEEK plate 6. In actual application, the screw 1 can be screwed in by the threads even if the inner wall of the liquid hole 610 is not designed with internal threads, but the torque required is relatively greater.

[0066] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
