Description

Technical Field

[0002] Endoscopic neurosurgery has the advantages of less trauma, high hematoma removal rate, short operation time and good surgical effect for partial removal of intracranial hematoma and cerebral hemorrhage. However, due to the small surgical space, after partial hematoma or lesion removal, there is tissue retraction and space collapse, which loses the subsequent operating space and increases the difficulty of the operation.

[0003] Doctors need to use a brain pressure plate to support a surgical space. The existing brain pressure plate is a flat plate-like structure with a relatively simple structure. The space it can support is too small, which makes the operation more difficult. Utility Model Content

[0011] Preferably, the angle between the handle fixing portion and the long handle of the sleeve is 80-100 degrees, and the handle fixing portion is an arc-shaped plate-like structure.

DETAILED DESCRIPTION

[0020] The technical solution of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments.

For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances. Example

[0024] like Figure 1-4As shown, the present embodiment provides a sleeve-type expandable brain compression plate, comprising a sleeve long handle 1, the sleeve long handle 1 is a long plate structure with an arc, and the two sides of one end of the sleeve long handle 1 are rotatably connected with a handle wing plate 2 by hinges, and the end of the sleeve long handle 1 close to the handle wing plate 2 is fixedly connected with a handle-wing combination part 3, and the handle-wing combination part 3 is a ring fan body structure, and the two ends of the handle-wing combination part 3 are respectively fixedly connected with a silicone liquid capsule 5, and the silicone liquid capsule 5 is connected to the handle-wing combination part 3, and a shunt pipe is embedded in the handle-wing combination part 3, and the two ends of the shunt pipe are respectively connected to the input ends of the silicone liquid capsule 5 at the two ends, and a low-pressure hydraulic pipe 4 is connected to the side of the handle-wing combination part 3, and one end of the low-pressure hydraulic pipe 4 is arranged through the handle-wing combination part 3 and is connected to the shunt pipe, and the end of the low-pressure hydraulic pipe 4 away from the handle-wing combination part 3 is connected with a pumping mechanism 6. In this embodiment, the handle wing plate 2 is initially in a storage state. At this time, there is no liquid in the silicone capsule 5, which is in a contracted state. Sterile saline is transported into the low-pressure hydraulic pipe 4 through the pumping mechanism 6. After passing through the low-pressure hydraulic pipe 4, the sterile saline enters the silicone capsules 5 at both ends from the shunt pipe. The silicone capsule 5 is filled with water to expand, and the increased volume drives the handle wing plate 2 to rotate and unfold, providing a surgical support space. The sterile saline is pumped out by the pumping mechanism 6, so that the sterile saline in the silicone capsule 5 is pumped out, the silicone capsule 5 contracts, and the handle wing plate 2 is pulled back to the folded state, and the brain pressure plate can be withdrawn at this time.

[0025] Specifically, the pumping mechanism 6 includes a mounting shell 61, one end of which is fixedly connected to a syringe 62, and the other end of which is provided with a propulsion assembly, which is fixedly connected to a push rod 621 of the syringe 62, and the output end of the syringe 62 is connected to the low-pressure hydraulic pipe 4. Sterile saline is added to the syringe 62, and the sterile saline is used as a carrier, which is highly safe. The push rod 621 of the syringe 62 is controlled by the propulsion assembly to reciprocate, thereby injecting or extracting the sterile saline into the silicone capsule 5, and completing the deployment or retraction operation of the handle wing plate 2.

[0026] Further, the propulsion assembly includes a threaded sleeve 63, a screw rod 64 and a pumping knob 65, one end of the threaded sleeve 63 is fixedly connected to the push rod 621 of the syringe 62, the screw rod 64 is threadedly connected to the threaded sleeve 63, the pumping knob 65 is fixedly connected to one end of the screw rod 64, and the pumping knob 65 is rotatably connected to the mounting housing 61. The pumping knob 65 is rotated, and the pumping knob 65 drives the screw rod 64 to rotate, and the rotation of the screw rod 64 drives the threaded sleeve 63 to move in the direction of the screw rod 64, thereby driving the push rod 621 of the syringe 62 to move forward and backward to complete the injection or liquid extraction operation. The movement of the push rod 621 of the syringe 62 is controlled by rotating the pumping knob 65, and the control is more precise and stable.

[0027] Furthermore, the sleeve long handle 1 is an arc-shaped plate-like structure. Through the arc-shaped flat and long structure, it can be attached to the inner wall of the narrow channel working sheath (puncture sheath), such as the narrow channel working sheath (puncture sheath) is a cylindrical structure, and can rotate along the inner wall.

[0028] Furthermore, one end of the low-pressure hydraulic pipe 4 is fixedly connected to the surface of the sleeve long handle 1, and the other end extends to the outside of the sleeve long handle 1. The low-pressure hydraulic pipe 4 is made of a material with a certain degree of rigidity and softness to ensure that the pipe does not collapse and has a certain degree of bending ability. It is fixed to the surface of the sleeve long handle 1 by pasting or other connection structures to prevent the low-pressure hydraulic pipe 4 from loosening during use and hindering surgical operations.

[0029] Furthermore, a handle fixing portion 7 is integrally formed at one end of the sleeve long handle 1 away from the handle-wing combination portion 3. Moreover, the included angle between the handle fixing portion 7 and the sleeve long handle 1 is 80-100 degrees, and the handle fixing portion 7 is an arc-shaped plate-like structure. The handle fixing portion 7 extending from the sleeve long handle 1 is convenient for the staff to hold and operate.

[0030] The working principle of the utility model is as follows: the handle wing plate 2 is in the storage state at the initial position. At this time, there is no liquid in the silicone capsule 5, which is in a contracted state. The pumping knob 65 is rotated, and the pumping knob 65 drives the screw 64 to rotate. The screw 64 rotates and drives the threaded sleeve 63 to move in the direction of the screw 64, thereby driving the push rod 621 of the syringe 62 to move forward, and the sterile saline is transported into the low-pressure hydraulic pipe 4. After the sterile saline passes through the low-pressure hydraulic pipe 4, it enters the silicone capsule 5 at both ends from the shunt pipe. The silicone capsule 5 is filled with water and expands. The increased volume pushes the handle wing plate 2 to rotate and unfold, providing a surgical support space. After the operation is completed, the pumping knob 65 is rotated in the opposite direction, and the sterile saline is extracted through the pumping mechanism 6, so that the sterile saline in the silicone capsule 5 is extracted, and the silicone capsule 5 shrinks, pulling the handle wing plate 2 back to the folded state, and the brain pressure plate can be withdrawn at this time.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them. Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present disclosure.
