Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a periosteal stripper for orbital surgery. Background Art

[0002] Orbital surgery is a common ophthalmic procedure. Currently, due to a lack of specialized instruments, orbital surgery often relies on instruments from otolaryngology and neurosurgery. This can lead to inconvenience for medical personnel during surgery, as some procedures are not well suited to the needs of orbital surgery, increasing the difficulty of operating the instruments. This reduces the comfort and accuracy of the medical personnel during the procedure, and can even exacerbate orbital damage during the procedure.

[0003] Currently, Chinese patent publication number CN203138819U discloses an orbital microsurgery periosteal stripper for ophthalmic orbital microsurgery. The device consists of a handle and stripping knives located at both ends of the handle. The handle is provided with concave and convex stripes. The stripping knife at one end of the handle is a flat, arc-shaped blunt stripping knife with a blunt blade edge. The other end of the handle is a straight, sharp stripping knife. The sharp stripping knife has no curvature and its blade edge is sharp. The straight, sharp stripping knife has the advantages of taking up little space, being easy to reach deep into the eye socket, and having a sharp blade that can easily make an incision on the periosteum. The utility model has both a flat, arc-shaped blunt stripping knife and a straight, sharp stripping knife, making orbital microsurgery convenient and safe, especially in the deep eye socket. This not only reduces the patient's pain but also saves surgical time.

[0004] However, due to the narrow space and deep position of the orbit, the surgical operation is relatively difficult. The existing periosteal strippers are prone to poor control of force during actual operation. If the force is not used carefully, it is likely to damage the nerves and muscles. Utility Model Content

[0005] Therefore, in view of the above problems, the present invention proposes a periosteal elevator for orbital surgery, which solves the problem that periosteal elevators for orbital surgery in the prior art are difficult to control the force and easily cause unnecessary damage to bones or muscles.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A periosteal stripper for orbital surgery comprises a handle and a first stripping knife and a second stripping knife respectively located at two ends of the handle.

[0008] The first stripping knife includes a first connecting rod and a first stripping head connected to each other, and the end of the first connecting rod away from the first stripping knife is connected to the handle; a plurality of reinforcing ribs are circumferentially arranged on the first connecting rod, the side surfaces of the reinforcing ribs are fixedly connected to the first connecting rod, and the bottom of the reinforcing ribs is fixedly connected to the handle.

[0009] The second stripping knife includes a second connecting rod and a second stripping head connected to each other, and the end of the second connecting rod away from the second stripping knife is connected to the handle; a serpentine structure is provided in the middle of the second connecting rod, and the serpentine structure includes a plurality of straight segments and arc segments connected in sequence.

[0010] Furthermore, the number of the arc segments is 2-4.

[0011] Furthermore, the first connecting rod and the first stripping head are integrally formed, and the second connecting rod and the second stripping head are integrally formed.

[0012] Furthermore, the first connecting rod and the handle are integrally formed, and the second connecting rod and the handle are integrally formed.

[0013] Furthermore, the first stripping head is a sharp blade head, the front end of the sharp blade head is a straight cutting edge, and the angle between the straight cutting edge and the axis of the handle is 30°-60°.

[0014] Furthermore, the second stripping head is a blunt blade head, and the front end of the blunt blade head is arc-shaped.

[0015] Furthermore, the handle is a structure that is wide in the middle and narrow at both ends, and grooves are provided on both sides of the middle of the handle.

[0016] Furthermore, the handle is provided with a rubber sleeve, and the rubber sleeve is provided with anti-slip patterns.

[0017] By adopting the above technical solution, the beneficial effects of the utility model are:

[0018] 1. The utility model has a simple structure and is easy to operate, and is suitable for periosteum stripping during orbital surgery. By providing reinforcing ribs on the first connecting rod, the strength and rigidity of the first connecting rod are improved, making the first connecting rod more secure, reducing the risk of deformation and bending of the first connecting rod during operation, and ensuring the safety of the surgical procedure; by providing a serpentine structure on the second connecting rod, the elastic potential energy of the second connecting rod is increased, allowing medical staff to obtain more refined tactile feedback during operation, facilitating precise control of the force and depth used. When the force is too great, the elastic structure can provide a certain buffering effect and feedback to the medical staff through rebound force, ensuring the stability of force control during surgery, achieving precise periosteum stripping, and avoiding unnecessary damage or trauma to surrounding bones, muscles and other tissues.

[0019] 2. By setting a rubber sleeve and anti-slip texture on the handle, the friction between the hand and the handle is increased, which can effectively prevent the medical staff's hand from slipping during the operation, ensuring the safety and reliability of the operation; by setting the handle to be wide in the middle and narrow at both ends, it is easy to hold, and at the same time, grooves are set on both sides of the middle of the handle, which is more in line with ergonomic principles, so that the handle can be held more closely when held, ensuring the stability of the grip.
