Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a sheath for a spinal surgery retractor.
Background
In current spinal surgery process, when using pedicle of vertebral arch screw to plant the method and carry out the operation of way nail behind the backbone to the patient, often need use to expose the device like the drag hook, carry out the tractive in backbone both sides, and then expose pedicle of vertebral arch needle point, because the position of needle point needs expose always, however current drag hook often uses hard material to make, and at the operation in-process, the drag hook tears the pulling for a long time of traction department muscle, can cause the damage to patient's muscle, causes painful sense to the patient.
Disclosure of Invention
The purpose of the invention is as follows: aiming at the defects of the prior art, the invention provides the sheath for the spinal surgery retractor, which can effectively avoid the damage of the retractor to muscles and has the characteristics of simple, quick and safe operation.
The technical scheme is as follows: the invention discloses a sheath for a spinal surgery retractor, which comprises a plate-shaped sheath body made of elastic materials, wherein the plate-shaped sheath body is composed of a plurality of sheath units, one surface of each sheath unit is provided with a glue layer, anti-sticking paper is arranged on the glue layer, the other surface of each sheath unit is provided with a plurality of horn-shaped bulges, and the openings of the horn-shaped bulges face the outer side of the sheath unit.
Preferably, a plurality of horn-shaped protrusions are uniformly distributed on the other surface of the sheath unit.
Preferably, the thickness of the sheath unit is not more than 1 mm; the height of the horn-shaped protrusion is not more than 1mm, and the maximum width is not more than 2 mm.
Preferably, a plurality of notches are uniformly distributed on the opening surface of the horn-shaped protrusion along the axial direction of the horn-shaped protrusion.
Preferably, the notch is a linear notch.
Preferably, the notch is a U-shaped notch.
Preferably, the notch is a V-shaped notch.
Preferably, the elastic material is rubber or silicone.
Preferably, the sheathing units are placed on the same release paper.
Preferably, the height of the horn-shaped protrusion is 0.5-0.8mm, and the maximum width is 1-1.5 mm.
Compared with the prior art, the invention has the beneficial effects that: the invention can play a role in buffering between the draw hook and the muscle, reduce the acting force of the draw hook on the muscle, reduce the direct abrasion of the draw hook on the muscle, effectively avoid the damage of the draw hook on the muscle, and has the characteristics of simple, rapid and safe operation.

Detailed Description
The technical solution of the present invention is described in detail below with reference to specific examples and drawings, but the scope of the present invention is not limited to the examples.
Examples
Fig. 1-2 show an embodiment of a sheath for a spinal surgery retractor according to the present invention, which comprises a plate-shaped sheath body made of latex, wherein the existing retractor has various shapes and no fixed structure, and if the existing retractor is designed into a traditional sleeve-shaped sheath, when the retractor has a design similar to a concave shape, the sheath cannot completely fit the hook, which causes the force application obstruction of the retractor to muscles during surgery, so that the plate-shaped sheath body is composed of two sheath units 1 with a thickness of 1mm, one side of each sheath unit 1 is provided with an adhesive layer 2, the adhesive layer 2 is provided with an anti-sticking paper 3, and the two sheath units 1 are arranged on the same anti-sticking paper 3, when in use, the sheath unit 1 can be torn off from the anti-sticking paper 3, the sticking can be performed according to the structure of the retractor, the sheath unit 1 can be cut according to the size of the retractor, so that the sheath unit 1 completely fits the retractor, avoid the application of force of drag hook to muscle to hinder, sheath unit 1 can also play the cushioning effect between drag hook and muscle, subduct the size of drag hook to the effort of muscle to and the direct wearing and tearing of drag hook to muscle.
Furthermore, eight horn-shaped protrusions 4 are uniformly distributed on the other surface of the sheath unit 1, the openings of the horn-shaped protrusions 4 face the outer side of the sheath unit 1, the height of each horn-shaped protrusion 4 is 0.6mm, and the maximum width of each horn-shaped protrusion 4 is 1 mm; therefore, the centralized action of a certain force application point of the draw hook on the muscle can be dispersed, the acting force of the draw hook on the muscle is further reduced, and the damage of the draw hook on the muscle of a patient is effectively reduced.
Fig. 3 is another embodiment of the present invention, which is based on fig. 1-2, wherein a plurality of notches 5 are uniformly distributed on the opening surface of the trumpet-shaped protrusion 4 along the axial direction thereof, and the notches 5 are linear, so that due to the arrangement of the notches 5, when the acting force of the retractor reaches the trumpet-shaped protrusion 4 through the sheath unit 1, the resultant force of the retractor can be further decomposed into more component forces, the force bearing points of muscles are increased, and the injury of the retractor to the muscles of the patient is further reduced.
Fig. 4 is another embodiment of the present invention, which is based on fig. 3, and the shape of the notch 5 on the trumpet-shaped projection 4 is replaced by a V-shaped structure, and the height of the trumpet-shaped projection 4 is replaced by 0.5mm, and the maximum width is replaced by 1.2 mm.
Fig. 5 is another embodiment of the present invention, which is based on fig. 3, and the shape of the notch 5 on the trumpet-shaped projection 4 is replaced by a U-shaped structure, and the height of the trumpet-shaped projection 4 is replaced by 0.8mm, and the maximum width is replaced by 1.5 mm.
As noted above, while the present invention has been shown and described with reference to certain preferred embodiments, it is not to be construed as limited thereto. Various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
