Problems solved by technology

[0004] In order to reduce the instability of the brain tissue exposed by the surgeon's assistant, most of the retractors currently used in brain departments are two-leaf retractors that can be adjusted and fixed. However, the two-blade retractors can only pull in two corresponding directions. When it is large, the brain tissue in the adjacent position will bulge, which will interfere with the surgical field of view

Embodiment Construction

[0046] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0047] like figure 1 As shown: in order to adjust the adjustable retractor at will according to the needs of the operation, so that the pulling depth and angle of the adjustable retractor meet the surgical requirements, pull the brain tissue with an appropriate external force, and fully expose the field of view of the surgical site, the present invention includes a retractor The base 1 and a number of hook pieces 2 arranged in the hook base 1, the hook pieces 2 are placed in the hook base 1 through the hook piece positioning control mechanism 3, and the hook pieces 2 correspond to the hook piece positioning control mechanism 3 one by one connected, when the pull hook pieces 2 are adjacent to each other in the pull hook base 1, they can form a cylindrical structure, and the pulling depth and pulling orientation of the connected pull hook pieces 2 can be adjusted...

Abstract

The invention relates to a drag hook, and especially relates to a minimally invasive tissue expander, and belongs to the technical field of medical instruments. According to the provided technical scheme, the minimally invasive tissue expander comprises a drag hook base and a plurality of drag hook sheets arranged in the drag hook base. The drag hook sheet is arranged in the drag hook base througha drag hook sheet positioning control mechanism. The drag hook sheets and the drag hook sheet positioning control mechanisms are connected with each other in a one-to-one manner. When the drag hook sheets in the drag hook base are close to each other, a cylindrical structure can be formed. Through the drag hook sheet positioning control mechanisms, required adjustment is performed on traction depth and traction orientations of the connected drag hook sheets. The adjustable drag hook sheets can be adjusted at will according to requirement of an operation, so that traction depth and angles of the adjustable drag hook sheets meet operation requirement, to pull a brain tissue by proper external forces and fully expose view of an operative site. The minimally invasive tissue expander is safe and reliable.

Description

technical field [0001] The invention relates to a retractor, in particular to a minimally invasive tissue spreader, which belongs to the technical field of medical instruments. Background technique [0002] In craniocerebral surgery, in order to fully expose the surgical field of view, it is necessary to use a spreader to stretch the tissues surrounding the lesion, so that the surgeon can operate on the lesion. However, the human brain tissue is very important. Excessive damage will cause excessive damage to the cerebral cortex, resulting in impaired neurological function of the patient, which may lead to irreversible neurological organ function damage. [0003] In order to reduce damage to the cerebral cortex, the surgical approach is very important, and it is necessary to avoid important functional cerebral cortex areas, and at the same time, it is necessary to avoid large blood vessels and other parts. This requires the surgeon to choose a good surgical access before ope...
