Detailed Description
The invention will be further described with reference to the following drawings and specific embodiments:
as shown in fig. 1, a combined aspirator 1 scalpel 2 special for brain surgery comprises an aspirator 1 and a scalpel 2 arranged in the aspirator 1; a rack 3 is arranged on a handle 21 of the scalpel 2, a gear which is meshed with the rack 3 and can enable the scalpel 2 to move up and down is arranged in the aspirator 1, the gear is fixed in the aspirator 1, and part of gear teeth of the gear penetrate out of the aspirator 1; the inner wall of the suction tube is connected with an elastic bag 5 with elasticity, the scalpel 2 penetrates through the elastic bag 5, and an elastic rod 6 capable of adjusting the volume of the elastic bag 5 is arranged on the scalpel 2 in the elastic bag 5.
Specifically, the shape of the aspirator 1 is a reducing shape with two small ends and a big middle part, the upper end of the aspirator is connected with an aspirator through a suction tube, and the other lower end of the aspirator is used for sucking and removing bleeding and exudates in the operation, so that the operation field is clear, and the pollution chance is reduced. In this embodiment, the inner diameter of the upper end of the aspirator 1 is 5mm, and the aspirator is made of stainless steel. The end of the scalpel 2 is provided with a scalpel head 22 with a replaceable scalpel blade 23, so that different types of scalpel blades 23 can be replaced as required; the surgical knife blade 23 is arranged close to the end part of the suction tube, the lower end of the suction tube is arranged into a suction device opening 7 matched with the surgical knife blade 23, and the surgical knife blade 23 can extend out of the suction device opening 7 and form a sealing effect on the suction device opening 7.
As shown in fig. 2 and 3, the gear is a cylindrical gear 4, and the end surfaces of the two sides of the gear are fixedly connected with the inner wall of the aspirator 1 through a connecting shaft 41; the cylindrical gear 4 is provided with a sliding groove 42 matched with the knife handle 21 of the scalpel 2, the sliding groove 42 is fixedly arranged on the outer side of the gear teeth of the cylindrical gear 4 and is fixedly connected with the end face of the gear teeth, and the scalpel 2 is inserted into the sliding groove 42 so that the scalpel 2 is limited to move in the sliding groove 42. An opening matched with the cylindrical gear 4 is formed in the wall of the aspirator 1, and partial gear teeth of the cylindrical gear 4 penetrate through the opening; the rack 3 on the knife handle 21 is transversely arranged, so that gear teeth of the rack 3 and the cylindrical gear 4 can be meshed with each other, and the rack is manually rotated to penetrate through the cylindrical gear 4 of the aspirator 1, so that the scalpel 2 can move up and down; when the elastic rod 6 is positioned in the middle of the elastic bag 5, the cylindrical gear 4 is pulled upwards, the scalpel 2 moves downwards until the scalpel extends out of the aspirator port 7, and the scalpel blade 23 is in a cutting state; then the cylindrical gear 4 is pulled downwards, the scalpel 2 moves upwards, and the scalpel blade 23 retracts into the aspirator 1 to play a role of a protective sleeve.
The upper end and the lower end of the elastic bag 5 are both fixedly connected to the inner wall of the aspirator 1 through a connecting rod 8, in the embodiment, the elastic bag 5 is made of rubber, openings for passing through the scalpel 2 are arranged at the two ends of the elastic bag, and the openings can keep the tightness of the cavity of the elastic bag 5. As shown in fig. 4, the elastic rod 6 includes a hollow cross-shaped main rod 61, a cross-shaped compression spring 62 is disposed in the middle of the main rod 61, and the four ends of the compression spring 62 are respectively connected with an auxiliary rod 63 that can be inserted into the main rod 61. When the elastic rod 6 is positioned in the middle of the elastic bag 5, the four auxiliary rods 63 extend outwards under the action of the elastic force of the pressure spring 62, and the elastic bag 5 is expanded outwards to form an approximate ellipsoid shape, so that the volume of the elastic bag 5 is the largest, and a certain gap is still kept between the elastic bag 5 and the inner wall of the expansion section of the aspirator 1; when the elastic rod 6 moves upwards or downwards, the elastic force of the elastic bag 5 enables the pressure spring 62 to be compressed, the four auxiliary rods 63 retract into the main rod 61, so that the volume of the elastic bag 5 expanded by the elastic rod 6 is gradually reduced, and when the elastic rod 6 is positioned at two ends of the elastic bag 5, the elastic bag 5 is approximately cylindrical; namely: the volume of the elastic bag 5 is the largest when the elastic rod 6 is in the middle of the elastic bag 5, and the volume of the elastic bag 5 is the smallest when the elastic rod is at the two ends.
Further, the initial position of the elastic rod 6 is in the middle of the elastic bag 5; when the cylindrical gear 4 is pulled downwards, the scalpel 2 moves upwards to drive the elastic rod 6 to move upwards, so that the volume of the elastic bag 5 is gradually reduced until the elastic rod 6 moves to the upper end of the elastic bag 5, and the volume of the elastic bag 5 is the minimum; the cylindrical gear 4 is pulled upwards, the scalpel 2 moves downwards, and the elastic rod 6 is driven to move downwards from the upper end part of the elastic bag 5, so that the volume of the elastic bag 5 is gradually increased until the elastic rod 6 is positioned in the middle of the elastic bag 5, and the volume of the elastic bag 5 is maximum; when the suction force of the suction machine connected to the upper end of the suction apparatus 1 is constant, the suction force at the suction apparatus port 7 is increased when the volume of the suction apparatus 1 occupied by the elastic bag 5 is increased, and the suction force at the suction apparatus port 7 is decreased when the volume of the suction apparatus 1 occupied by the elastic bag 5 is decreased, so that the suction force of the suction apparatus 1 can be adjusted without replacing the suction machine.
When in use, when the surgical knife 2 of the suction apparatus 1 needs to be in a suction state, the suction apparatus 1 is connected with a suction machine through a suction tube, the surgical knife blade 23 is in a body retracted into the suction apparatus 1, and the bleeding and exudation in the operation can be sucked through the suction apparatus opening 7; when the suction force of the suction apparatus 1 needs to be adjusted, the cylindrical gear 4 is shifted downwards, the scalpel 2 moves upwards, and the elastic rod 6 is driven to move upwards, so that the volume of the elastic bag 5 is gradually reduced, and the suction force at the suction apparatus opening 7 is increased; instead, the cylindrical gear 4 may be pulled up to reduce the suction force at the aspirator port 7. When the scalpel 2 of the aspirator 1 needs to be in a cutting function, the cylindrical gear 4 is pulled upwards until the scalpel blade 23 extends out of the aspirator port 7, and the aspirator port 7 is sealed; when the surgical knife blade 23 is cut, the cylindrical gear 4 is pushed downwards, so that the surgical knife blade 23 retracts into the suction apparatus 1.
