Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to a scalp retractor, a fixator and a craniocerebral retraction device. Background Technique

[0002] In neurosurgery, a scalp retractor is commonly used to retract and fix the scalp. As shown in the attached Figure 1 figure, the existing scalp retractor mainly consists of a cartridge spring clip 1, a spring coil 2 and a claw-shaped hook 3. One end is two sharp claw-shaped hooks 3, and the other end is a cartridge spring clip 1 composed of two reed pieces, and the middle is connected by a fine spring coil 2 with a length of 12 CM.

[0003] During clinical use, the cartridge spring clip 1 of the scalp retractor will be pulled back by the pulling force of the spring coil 2 during the actual process of clamping the surgical drape and cannot be clamped and fixed, which affects the surgical field and increases the surgical difficulty. At present, a rubber band is often used to fix the scalp retractor on the surgical drape, but the pulling force of this method will move with the surgical drape and is not stable, and still has an adverse effect on the surgical field.

[0004] Therefore, at present, it is urgent to solve the problem that the scalp retractor cannot be clamped and fixed. Content of the Utility Model

[0005] The purpose of the utility model is to overcome the problem that the scalp retractor cannot be clamped and fixed, and proposes a scalp retractor, a fixator and a craniocerebral retraction device.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A scalp retractor includes an elastic connecting piece. One end of the elastic connecting piece is connected to a fixing pliers, and the other end of the elastic connecting piece is connected to a claw-shaped hook. The fixing pliers are provided with pliers arms. There are two pliers arms. The two pliers arms are cross-shaped and one end is hinged through a rotating part. One end of each of the two pliers arms is integrally provided with a pliers mouth, and the other end of each of the two pliers arms is installed with a clamping plate. Anti-slip tooth plates are provided on one side of the two clamping plates, and the two anti-slip tooth plates are meshed and locked.

[0008] Further, tooth patterns are provided on the surface of the anti-slip tooth plates, and the tooth patterns of the two anti-slip tooth plates are staggered with each other.

[0009] Further, a fixing piece is provided on the inner side of one of the pliers arms. The fixing piece is provided with a rod body, and a slot hole is provided on the rod body. The slot hole of the rod body is connected to one end of the elastic connecting piece.

[0010] Further, the free length range of the elastic connecting piece is 5 cm - 10 cm, and the elastic connecting piece is made of a spring coil or an elastic band.

[0011] Further, the length of the fixed forceps is 10 cm - 14 cm, and the length of the forceps mouth is 1 cm - 4 cm.

[0012] Further, serrations are provided at the clamping end of the fixed forceps.

[0013] Further, finger rings are provided on the splints.

[0014] A scalp retractor fixator includes a rotating block, a positioning bolt, a slider, a sliding groove and a connecting buckle. The positioning bolt is screwed into the slider and extends out of both ends of the slider. The rotating block is provided at one end of the positioning bolt. The connecting ring is fixed to one side of the slider, and a sliding groove is provided at the end of the slider away from the rotating block.

[0015] Further, the connecting ring is clamped and fixed with the fixed forceps of a scalp retractor.

[0016] A craniotomy retraction device, a scalp retractor fixator is installed on the annular head ring of the craniotomy retraction device, and the scalp retractor fixator uses the scalp retractor fixator described above.

[0017] Compared with the prior art, the present utility model has the following beneficial technical effects:

[0018] For the fixed forceps proposed by the present utility model, anti-slip tooth plates are provided on both splints. The clamping method of meshing and locking of the two anti-slip tooth plates is stable and there is no risk of falling off, so that the scalp retractor can be kept fixed and a good surgical field can be formed.

[0019] For the elastic connecting piece proposed by the present utility model, it is connected with the fixed forceps through the fixing piece on the inner side of the forceps arm. The connection between the elastic connecting piece and the fixed forceps is stable and does not fall off, and will not affect the overall stability of the scalp retractor.

[0020] The free length of the elastic connecting piece proposed by the present utility model is 5 cm - 10 cm, which is suitable for any neurosurgical operation.

[0021] Serrations are provided at the front end of the fixed forceps of the present utility model, which further enhances the stability of the fixed forceps and makes the fixed forceps more reliable.

[0022] The scalp retractor fixator proposed by the present utility model is applicable to the annular head ring of the head frame for neurosurgical craniotomy operations, which not only increases the usage methods of the scalp retractor, but also expands the application scenarios of the head frame.
