Description

Technical Field

[0001] The invention relates to the technical field of neurosurgery, and in particular to an auxiliary nailing device. Background Art

[0002] In neurosurgery and other operations, it is usually necessary to open the skull for necessary surgical operations. After the operation is completed or the purpose of the operation is achieved, the separated bone flap is reconnected and fixed to the skull to protect the intracranial tissue and maintain normal intracranial pressure. The bone flap and the skull are generally connected by a connecting piece. Before the operation, the bone flap and the connecting piece are first fixed together by titanium nails, and then the bone flap with the connecting piece locked is locked on the skull by titanium nails, so that the skull bone window repair operation is realized. Before performing the skull bone window repair operation, the bone flap and the connecting piece need to be nailed together. At present, most medical staff hold the bone flap and the connecting piece in one hand and nail them with the other hand; because the bone flap and the connecting piece are pinched by one hand at the same time, it will be inconvenient to nail them, and it is easy to nail them crookedly. What's more, when using electric tools to nail quickly, the working blade will hurt the hands of medical staff and cause secondary infection. Therefore, there is an urgent need for a device that can reduce the complexity of surgical operations and safely and quickly assist in nailing the bone flap. Summary of the invention

[0031] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" 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, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] The present invention provides a nailing auxiliary device, such as Figure 1 and Figure 7 As shown, it includes a base 1 and a connecting piece clamping mechanism, the top of the base 1 is a rounded boss 2, the bone flap 14 is arranged on the rounded boss 2, the side of the base 1 is provided with a connecting piece clamping mechanism, the connecting piece clamping mechanism is provided with a positioning groove 3, and the connecting piece 16 is arranged in the positioning groove 3 and fixed by the connecting piece clamping mechanism. The auxiliary nailing device provided by the present invention has a simple structure and is easy to operate, and can clamp connecting pieces 16 of different thicknesses and shapes. By setting the connecting piece clamping mechanism, the phenomenon of skewing of nailing can be prevented, and the nailing can be adjusted in multiple directions and angles, which increases the efficiency of nailing, and the nailing operation platform is far away from the hand-held place of medical staff, which is safer.

[0033] Embodiment 1:

[0034] Reference Figure 1 to Figure 6 The connecting piece clamping mechanism includes a pressing piece 4 and a step platform 5, the step platform 5 is arranged on the side of the base 1, the pressing piece 4 is connected to the step platform 5, a positioning groove 3 is opened on the step platform 5, a buckle 6 is provided on the pressing piece 4, the buckle 6 passes through the through hole 17 on the step platform 5 and is fixed by a spring member 7, the spring member 7 is sleeved on the buckle 6, and a clamping groove 8 that can be telescopically extended up and down can be formed between the pressing piece 4 and the step platform 5, and the spring member 7 is arranged between the buckle 6 and the step platform 5, wherein the base 1 and the pressing piece 4 are made of medical polymer materials; further, as Figure 2 As shown, three through holes 17 and two positioning grooves 3 are provided on the step platform 5. Before performing a neurosurgery operation, the bone flap 14 and the connecting piece 16 are first fixed together by titanium nails 15, and then the bone flap 14 with the connecting piece 16 locked is locked on the skull by titanium nails 15, so that the skull bone window repair operation is realized. Specifically, the connecting piece 16 is first inserted into the positioning groove 3, and the buckle 6 on the pressing piece 4 and the elastic force of the spring member 7 make the pressing piece 4 clamp the connecting piece 16 in the positioning groove 3, thereby playing the role of fixing and clamping the connecting piece 16, so that the connecting piece is in the positioning groove. 3 and the step platform 5 are fixed in a clamping groove 8 that can be extended and retracted up and down. Under the action of the spring member 7, the pressing plate 4 will always maintain a certain force on the connecting plate 16 to prevent the connecting plate 16 from moving up and down, thereby playing a clamping role. The bone flap 14 is then overlapped on the rounded boss 2, and the titanium nail 15 is inserted from above the connecting plate 16 to lock the connecting plate 16 and the bone flap 14 together. During the process of inserting the titanium nail 15, the medical staff can arbitrarily adjust the angle and direction on the rounded boss 2 according to the inner arc of the bone flap 14 and the length of the connecting plate 16 until it is suitable for the insertion of the titanium nail 15.

[0035] Furthermore, the pressing plate 4 and the step platform 5 are both arc-shaped to fit the shape of the bone flap 14. The step platform 5 is provided with reinforcing ribs 9 to enhance the aesthetics and stability. The top of the step platform 5 is higher than the top of the base 1, so that the connecting plate 16 is located above the bone flap 14 to facilitate the insertion of the titanium nail 15.

[0036] Embodiment 2:

[0037] Reference Figure 7 to Figure 10 The connecting piece clamping mechanism includes an upper clamping piece 10, a torsion spring, a support shaft 12 and a lower clamping piece 11. The lower clamping piece 11 is arranged on the side of the base 1. A positioning groove 3 is opened on the lower clamping piece 11. A protrusion 13 is provided on the upper clamping piece 10, and the protrusion 13 is connected with the positioning groove 3. The connecting piece 16 is arranged in the positioning groove 3. The upper clamping piece 10 and the lower clamping piece 11 are connected and connected by the support shaft 12. A torsion spring is provided on the support shaft 12. The torsion spring drives the upper clamping piece 10 to move up and down to clamp or release the connecting piece 16 in the positioning groove 3. Specifically, by pressing the upper clip 10, the connecting piece 16 is first inserted into the positioning groove 3, the placement position of the connecting piece 16 is found, and then the upper clip 10 is loosened so that the protrusion 13 on the upper clip 10 clamps the connecting piece 16 in the positioning groove 3 of the lower clip 11, thereby playing the role of fixing and clamping the connecting piece 16. Under the action of the torsion spring, the upper clip 10 will always maintain a certain force to press on the connecting piece 16 to prevent the connecting piece 16 from moving up and down, thereby playing a clamping role, and then the bone flap 14 is overlapped on the rounded boss 2, and the titanium nail 15 is inserted from above the connecting piece 16 to lock the connecting piece 16 and the bone flap 14 together. When the position of the connecting piece 16 needs to be adjusted, the upper clip 10 is pressed again to adjust the position of the connecting piece 16. During the process of inserting the titanium nail 15, medical staff can arbitrarily adjust the angle and direction on the rounded boss 2 according to the inner arc of the bone flap 14 and the length of the connecting piece 16 to improve operating efficiency.

[0038] Furthermore, a retaining spring is provided at the end of the support shaft 12 to prevent the support shaft 12 from falling off during rotation, and the top end of the lower clip 11 is higher than the top of the base 1 to facilitate nailing.

[0039] In addition, the base 1 can be cylindrical or trumpet-shaped with a thin top and a thick bottom, and the top of the thin end of the base 1 is a rounded boss 2, which is biased to adjust the angle of the bone flap 14. A plurality of support bars 18 are provided on the inner side of the base 1 to increase the stability of the base 1.
