Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0030] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0031] The present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings.
[0032] See also Figure 1 and Figure 2 As shown, this embodiment provides a preoperative intraspinal positioning needle, including a positioning needle body 100; the outer wall of the positioning needle body 100 is provided with a depth scale mark 200; the upper part of the positioning needle body 100 is provided with an easy-to-break notch 300 so that the positioning needle body 100 can be broken from the corresponding easy-to-break notch 300.
[0033] Specifically, before spinal surgery, medical personnel, with the assistance of a fluoroscopic instrument, insert the positioning needle body 100 into the target vertebra for surgery and confirm it through the fluoroscopic instrument. During the puncture process, medical personnel can confirm the puncture depth of the positioning needle body 100 according to the setting of the depth scale mark 200 to avoid damage to the vertebra by the positioning needle body 100, which is convenient for medical personnel to operate. After puncturing to the corresponding depth, medical personnel can break the positioning needle body 100 exposed outside the skin through the easy-to-break notch 300, thereby not affecting the formal operation.
[0034] It should be noted that the positioning needle body 100 of the preoperative spinal positioning needle provided in this embodiment is provided with a depth scale mark 200. Therefore, when the positioning needle body 100 is knocked into the patient's body, the medical staff can clearly know the insertion depth of the positioning needle body 100, thereby avoiding the positioning needle body 100 being inserted too deeply and causing adverse effects on the spine.
[0035] It should also be noted that the positioning needle body 100 of the preoperative intraspinal positioning needle provided in this embodiment is provided with an easy-to-break notch 300. After the medical staff knocks the positioning needle body 100 into the patient's body, the positioning needle body 100 exposed outside the patient's body can be broken through the easy-to-break notch 300, thereby reducing the length of the positioning needle body 100 exposed outside the patient's body, or even eliminating the length of the positioning needle body 100 exposed outside the patient's body. Therefore, in the subsequent formal operation, the doctor can directly cut the patient's skin from the positioning needle body 100, without excessively avoiding the positioning needle as in the prior art, so that the incision can directly correspond to the surgical position of the vertebra after it is opened.
[0036] See also Figure 1 and Figure 2 As shown, in an optional solution of this embodiment, the positioning needle body 100 adopts a solid needle body.
[0037] Specifically, the positioning needle body 100 of the preoperative spinal positioning needle provided in this embodiment adopts a solid needle body. Through such a configuration, the resistance encountered by the positioning needle body 100 is reduced, and it is easier to knock it into the patient's body.
[0038] It should be noted that the positioning needles in the prior art are all of a sleeve-type structure, that is, the positioning needle is a hollow sleeve structure, so the puncture resistance is large.
[0039] See also Figure 1 and Figure 2 As shown, in an optional solution of this embodiment, a striking seat 400 is provided at the tail end of the positioning needle body 100 so that medical personnel can strike the positioning needle body 100 .
[0040] Specifically, a striking seat 400 is provided at the rear end of the positioning needle body 100 , and medical personnel can use a small tool to strike the striking seat 400 , thereby knocking the positioning needle body 100 into the patient's body.
[0041] Among them, the provision of the striking seat 400 enables medical personnel to strike the positioning needle body 100 more conveniently.
[0042] See also Figure 1 and Figure 2 As shown, in an optional solution of this embodiment, a transition rib 410 is provided between the striking seat 400 and the positioning needle body 100 .
[0043] Specifically, a transition rib 410 is provided between the striking seat 400 and the positioning needle body 100. The provision of the transition rib 410 strengthens the connection firmness between the positioning needle body 100 and the striking seat 400, thereby preventing the striking seat 400 from tilting relative to the positioning needle body 100 due to the medical staff knocking the striking seat 400 crookedly.
[0044] In an optional solution of this embodiment, the outer wall of the striking seat 400 is provided with a friction surface for increasing the friction force.
[0045] Specifically, a friction surface is provided on the outer wall of the striking seat 400. The friction surface is provided to increase the friction force of the striking seat 400 so that volunteers can hold it better and avoid the striking seat 400 from slipping during the striking process.
[0046] Herein, a rubber layer may be provided on the outer wall of the striking seat 400 or the roughness of the outer wall of the striking seat 400 may be increased.
[0047] In an optional solution of this embodiment, the ratio of the diameter of the positioning needle body 100 to the depth of the easy-to-break notch 300 is not less than 3.
[0048] Specifically, the ratio of the diameter of the positioning needle body 100 to the depth of the easy-to-break notch 300 can be set to 3, or the ratio of the diameter of the positioning needle body 100 to the depth of the easy-to-break notch 300 can be set to 4, or the ratio of the diameter of the positioning needle body 100 to the depth of the easy-to-break notch 300 can be set to 5, or the ratio of the diameter of the positioning needle body 100 to the depth of the easy-to-break notch 300 can be set to 6, or the ratio of the diameter of the positioning needle body 100 to the depth of the easy-to-break notch 300 can be set to 7, or the ratio of the diameter of the positioning needle body 100 to the depth of the easy-to-break notch 300 can be set to 8. Through such a setting, it can be ensured that the medical staff can break the positioning needle body 100 at the easy-to-break notch 300, and the positioning needle body 100 will not break during the knocking process.
[0049] See also Figure 1 and Figure 2 As shown, in an optional solution of this embodiment, the number of the easy-to-break notches 300 is multiple.
[0050] There are two easy-to-break notches 300 , which are symmetrically arranged on the outer wall of the positioning needle body 100 , and have the same height.
[0051] Specifically, in actual use, the preoperative intraspinal positioning needle provided in this embodiment can be set in a plurality of models of different sizes, and models of corresponding lengths are used for corresponding patients, so that after the positioning needle body 100 is inserted into the patient's body to a set depth, the easy-break notch 300 can be located at the skin, so that after the medical staff breaks the positioning needle body 100 through the easy-break notch 300, the length of the positioning needle body 100 exposed outside the skin is as short as possible.
[0052] In addition, two easy-to-break notches 300 may be symmetrically arranged at the same height of the positioning needle body 100 , so that medical personnel can more conveniently break the positioning needle body 100 .
[0053] In addition, a red color mark is provided in the easy-folding notch 300 so that medical personnel can identify the easy-folding notch 300 .
[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
