Problems solved by technology

[0002] In the existing spinal surgery process, such as using the pedicle screw implantation method to perform posterior spinal screw surgery on patients, it is often necessary to use exposure devices such as retractors to pull on both sides of the spine, thereby exposing the vertebral arch Because the position of the needle entry point needs to be exposed all the time, however, the existing retractors are often made of hard materials. During the operation, the long-term tearing of the muscles at the traction site by the retractors will damage the patient's muscles. Injury, causing pain to patient

Embodiment

[0023] Figure 1-2 It is an embodiment of a sheath used for spinal surgery retractors in the present invention, including a plate-shaped sheath body made of latex material. Due to the various shapes of existing retractors, there is no fixed structure. If it is set as a traditional Sheath-like sheath, when the pull hook has a similar concave design, the sheath cannot completely fit the hook, resulting in the hindrance of the force exerted by the pull hook on the muscles during the operation, so the plate-shaped sheath body is set with two 1mm thickness The sheath unit 1 is composed of a sheath unit 1, and one side of the sheath unit 1 is provided with an adhesive layer 2, and the adhesive layer 2 is provided with a release paper 3, and the two sheath units 1 are placed on the same release paper 3, when in use , the sheath unit 1 can be torn off from the anti-adhesive paper 3, and pasted according to the structure of the hook, and the sheath unit 1 can also be cut according to t...

The invention has the characteristics of simple, quick and safe operation.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a sheath used for a retractor for spinal surgery. Background technique [0002] In the existing spinal surgery process, such as using the pedicle screw implantation method to perform posterior spinal screw surgery on patients, it is often necessary to use exposure devices such as retractors to pull on both sides of the spine, thereby exposing the vertebral arch Because the position of the needle entry point needs to be exposed all the time, however, the existing retractors are often made of hard materials. During the operation, the long-term tearing of the muscles at the traction site by the retractors will damage the patient's muscles. cause injury and pain to the patient. Contents of the invention [0003] Purpose of the invention: The purpose of the present invention is to address the deficiencies of the prior art and provide a sheath for a retractor for spinal ...
