Abstract

OCR 09WP 04 / 11 / 2568 A transparent brain retractor tube is a device used to assist in brain surgery. The transparent brain retractor tube, used for brain surgery, consists of two main parts, as shown in the figure. 1. It is the central core (1) which is in the form of a bullet-shaped cylindrical rod that can be inserted into the expanding tube (2) which has the following characteristics: It is a long cylindrical tube with a handle.

Claims

OCR 09WP 04 / 11 / 2568 1. The transparent dilator tube for brain surgery consists of two main parts: the central shaft (1) and the dilator tube (2). The core (1) is shaped like a bullet-shaped cylinder with one end tapering and serving as Inserted into the head passage for brain surgery. Inside the central core (1) there is a hole in the center (3) located in the center according to The longitudinal axis (1) through which the central hole (3) serves to insert the device, the rod of the brain-guided system device. (brain navigator system) can go down. At one end of the central axis (1) there is a gripping axis (5) which has the following characteristics It is shaped as an overhang around the central edge (1) to allow the central shaft to be grasped and pulled. (1) Exit the expansion tube (2) Its special characteristics include: In the outer center of the central shaft (1), there is a small pin (6) protruding from the body. The central shaft (1) is attached to the clamp (9) of the expansion tube (2), which the bolt (6) serves to prevent the tube from slipping. Extended scope for brain surgery to prevent dislodging during the insertion of instruments into the brain. The dilating tube (2) is a long cylindrical tube with open ends, serving the function of For inserting the central shaft (1) or inserting the device used for the procedure, by the outer surface of the speculum. The expansion tube (2) has a symbol indicating the depth level of the device. At one end of the expansion tube (2) there is The flared shape and handle (7) has a flat shape that serves to grip, hold, adjust the position or pull the expansion tube (2). It is removed from the patient's brain tissue. In addition, the flat gripping area (7) is thick enough to hold it in place. With the flat spatula retractor system clamp holding the spatula (2) in place. To keep it still, inside the expansion tube (2) there is a small clamp (9) which holds the bolt (6) from the center axis (1) in order to Secure the central shaft (1) and the dilating tube (2) so they do not slip apart while inserting the device into the brain tissue.

2. A transparent speculum for brain surgery, according to claim 1, at the other end of the central hole (3) there is an opening. (4) At least one hole serves to allow fluid in the brain tissue, such as blood or cerebrospinal fluid. (cerebrospinal fluid) can flow through, and the opening (4) serves to indicate that the end of the central axis (1) is in position. Where pathological conditions were found.

3. Transparent dilator for brain surgery, according to claim 1, where the grip area (7) shall have at least one notch (8). One groove 4. Transparent dilating tube for brain surgery, according to claim 1, where the central core (1) is longer than the dilating tube. (2)
