Description

  The present invention relates to a surgical brain spatula used for neurosurgery and the like.

  Conventionally, in neurosurgery and the like, the surgical field is secured by pressing the opened brain with a surgical spatula.

  In recent years, neurosurgery tends to shift to minimally invasive surgery that reduces the wound size in order to minimize the invasion of patients. In minimally invasive surgery, neuroendoscopic surgery using a soft or rigid endoscope is also performed, and the wound that opens is extremely small compared to surgery under direct vision. Surgery is performed by inserting an endoscope or the like from the small wound into the brain.

  Surgery performed through a small wound on the head requires very careful operation and skill.

  Therefore, an object of the present invention is to provide a surgical brain spatula that contributes to the simplification of the above operation.

  In order to solve the above problems, the invention according to claim 1 employs a surgical brain spatula in which a spatula is fixed to the wall of a flexible tube.

  The invention according to claim 2 employs a surgical brain spatula in which the spatula has plasticity in the surgical brain spatula according to claim 1.

  The invention according to claim 3 employs a surgical brain spatula in which the flexible tube has a plurality of treatment holes in the surgical brain spatula according to claim 1 or claim 2.

  According to the invention according to claim 1, since the spatula is a surgical spatula fixed to the wall of the flexible tube, the surgical path from the open head to the affected part can be secured by the spatula during the operation. The surgical instrument can be taken in and out and various fluids can be supplied or discharged by using the hole of the flexible tube as a treatment hole. Therefore, surgery can be performed more safely and easily.

  According to the invention of claim 2, in the surgical spatula according to claim 1, since the spatula has plasticity, the brain spatula and the tube can be freely bent and the shape after bending can be maintained. it can. Therefore, a more appropriate treatment can be performed on the affected area.

  According to the invention according to claim 3, in the surgical brain spatula according to claim 1 or 2, since the flexible tube has a plurality of treatment holes, the treatment holes of the tube are properly used for various applications. For example, it can be used properly for insertion and removal of endoscopes, forceps and the like, suction and discharge of liquid from the surgical field, scouring, etc., and injection of cleaning liquid. Therefore, more effective surgical treatment can be performed.

  The best mode for carrying out the invention will be described below with reference to the drawings.

<Embodiment 1>
As shown in FIG. 1, this surgical spatula includes a flexible tube 1 and a spatula 2.

  The flexible tube 1 is made of, for example, silicon rubber. The tube 1 may be opaque, but is preferably formed to be transparent or translucent.

  The spatula 2 is formed, for example, as an elongated plate. The spatula 2 may be rigid, but is preferably formed as plastic. The plastic spatula 2 is formed by performing nickel plating on a copper plate as a base material. This plastic spatula 2 is bendable and maintains its state even after being bent.

  A slit 3 extending along the cylindrical generatrix of the tube 1 is formed in the wall thickness of the tube 1, and the spatula 2 is fixed to the wall of the tube 1 by inserting the spatula 2 into the slit 3. And integrated with the tube 1. Integration of the spatula 2 and the tube 1 can be performed by inserting the spatula 2 into the slit 3 of the slitted tube. It can be carried out. Moreover, it can also carry out by sticking the spatula 2 with an adhesive agent, an adhesive tape, etc. to the inner wall surface or outer wall surface of the tube without the slit 3.

  Next, the operation of the surgical brain spatula with the above configuration will be described.

  As shown in FIG. 2, a small-diameter hole 4a is drilled in the head 4 in neurosurgery.

  Prior to insertion of the surgical spatula, the spatula 2 is bent into a desired shape using the plasticity of the spatula 2. The tube 1 bends along the spatula 2 due to its flexibility, and the opening 6 at its tip faces the affected area.

  A surgical spatula is inserted into the inside of the brain 5 from the small-diameter hole 4a which is an open head, and a surgical route to the affected part is secured.

  Using the hole of the flexible tube 1 as the treatment hole 1a, a surgical instrument such as an endoscope or forceps (not shown) is taken in and out to treat the affected part. Further, the cleaning liquid is injected and discharged through the treatment hole 1a, and smoke generated by an electric knife is sucked. During these various treatments, the wall of the tube 1 prevents exposure of brain tissue. Thereby, a surgical instrument etc. can be taken in and out safely and easily.

<Embodiment 2>
As shown in FIG. 3, the flexible tube in the surgical brain spatula has a plurality of treatment holes.

  That is, the flexible tube includes the thick main tube 7 and the thin attached tubes 8, 9, 10, and the thin attached tubes 8, 9, 10 are attached to the outer peripheral surface of the main tube 7. The holes of the tubes 7, 8, 9, 10 can be used for various purposes as separate treatment holes 7a, 8a, 9a, 10a. For example, the main tube 7 is used for taking in and out an endoscope, forceps, etc. Use the first accessory tube 8 for injecting cleaning fluid, the second accessory tube 9 for suctioning cleaning fluid, and the third accessory tube 10 for exhausting smoke generated by an electric knife. Can do.

  The integration of the main tube 7 and the accessory tubes 8, 9, and 10 can be performed by simultaneously extruding the main tube 7 and the accessory tubes 8, 9, and 10. It can also be carried out by adhering 9, 10 with an adhesive, an adhesive tape or the like.

  The present invention is not limited to the first and second embodiments. For example, in the above embodiment, the tube is shorter than the spatula, but the tube may protrude from the tip of the spatula. You may make it extend longer from the rear end. Various treatment holes can also be formed by partitioning the inside of the tube with a partition wall.

It is a perspective view of the surgical brain spatula which concerns on Embodiment 1 of this invention. It is a perspective view which shows the usage condition of the surgical brain spatula shown in FIG. It is a perspective view of the surgical brain spatula which concerns on Embodiment 2 of this invention.
