Abstract

The utility model discloses a surgical stripping device, which comprises a handle and a stripping head fixed at one end of the handle, wherein the top surface of the stripping head is a smooth plane, and the axial included angle between the top surface of the stripping head and the handle is 110-130 degrees; the bottom surface of the stripping head is an arc surface, and the top end of the stripping head is an obtuse angle. Has the advantages that: the stripping device can extend into potential gaps of nerves and ligaments at a proper angle, the stripping head is pried into the bottom surface to be pushed away, and meanwhile, the potential gaps can be expanded through transverse pushing; when the stripping device extends into the ligament and under the nerve, the bottom surface of the stripping device is smoothly followed by an obtuse angle, and the pressure type following of the non-right-angle feeler hook avoids the risk of nerve injury; especially suitable for spinal stenosis; the device is safe and comfortable in operation angle in the bony barrier space between the upper vertebral body and the lower vertebral body, and protects the spinal cord.

Description

Surgical stripping device

The technical field is as follows:

the utility model relates to medical equipment, in particular to a stripping device for operation.

Background art:

in spinal surgery, dissectors are often used in separating nerve-ligament gaps, nerve-bone and ligament-bone potential gaps, but currently, right-angle cylindrical nerve hooks and wide-flat nerve dissectors are clinically used. When the two tools are used in the operation, the hand feeling of an operator is often not satisfactory, and the risk of nerve injury exists. The present peeling apparatus is thus designed.

The utility model has the following contents:

the utility model aims to provide a surgical stripping device which can conveniently strip ligaments and nerves from surrounding tissues in a surgery.

The utility model is implemented by the following technical scheme: the surgical stripping device comprises a handle and a stripping head fixed at one end of the handle, wherein the top surface of the stripping head is a smooth plane, and the included angle between the top surface of the stripping head and the axis of the handle is 110-130 degrees; the bottom surface of the stripping head is an arc surface, and the top end of the stripping head is a plane.

The utility model has the advantages that: compared with the prior art, the stripping device can extend into potential gaps of nerves and ligaments at a proper angle, the stripping head is pried into the bottom surface to be pushed away, and meanwhile, the potential gaps can be expanded by transverse pushing; when the stripping device extends into the ligament and under the nerve, the bottom surface of the stripping device is smoothly followed by an obtuse angle, and the pressure type following of the non-right-angle feeler hook avoids the risk of nerve injury; especially suitable for spinal stenosis; the device is safe and comfortable in operation angle in the bony barrier space between the upper vertebral body and the lower vertebral body, and protects the spinal cord.

Description of the drawings:

fig. 1 is an overall schematic view of the present invention.

Fig. 2 is a front view of the present invention.

Fig. 3 is a right side view of fig. 2.

Handle 1, stripping head 2, stripping head top surface 21, stripping head bottom surface 22, stripping head top end 23.

The specific implementation mode is as follows:

example (b): as shown in fig. 1 to 3, the posterior longitudinal spinal surgery peeling device comprises a handle 1 and a peeling head 2 fixed at one end of the handle, wherein the peeling head 2 is spoon-shaped in overall shape, the top surface 21 of the peeling head 2 is a smooth plane, and the included angle between the top surface 21 of the peeling head and the axis of the handle 1 is 110-130 degrees; the bottom surface 22 of the peeling head 2 is an arc surface, and the top end 23 of the peeling head 2 is an obtuse angle.

Instructions for use: taking an anterior cervical spine operation as an example, the skin, the subcutaneous tissues and the platysma of the neck are incised, the vascular sheath and the gap between the visceral sheaths are separated, the anterior cervical intervertebral space is exposed, the cervical intervertebral disc is excised after positioning, the posterior longitudinal ligament is exposed, the stripping head 2 is used for stretching between the bone and the posterior longitudinal ligament, if necessary, the posterior longitudinal ligament can be stretched between the posterior longitudinal ligament and the dura mater from the side, the posterior longitudinal ligament is picked up, the posterior longitudinal ligament is cut off by a sharp knife, and the intervertebral disc tissues in the gap between the dura mater and the posterior longitudinal ligament are explored.

Claims

1. The surgical stripping device comprises a handle and a stripping head fixed at one end of the handle, and is characterized in that the overall stripping head is spoon-shaped, the top surface of the stripping head is a smooth plane, and the included angle between the top surface of the stripping head and the axis of the handle is 110-130 degrees; the bottom surface of the stripping head is an arc surface, and the top end of the stripping head is an obtuse angle.
