Description

Technical Field

[0001] This utility model relates to the field of medical surgical auxiliary device technology, specifically an arthroscopic nerve release device. Background Art

[0002] With the development of sports medicine and arthroscopic technology, minimally invasive surgery has become widely accepted. Arthroscopic procedures such as wrist joint release or suprascapular nerve surgery are increasingly common. However, because arthroscopic procedures currently often use plasma scalpels, blades, or small needle knives, there is a risk of accidentally damaging the nerve. This makes the procedure even more difficult for beginners. Furthermore, using ordinary blades to release the restraining structures on the nerve surface often leads to recurrence, as these restraining structures can easily regrow and re-adhere.

[0003] Current methods for releasing nerves in patients often use ion scalpels, blades, or small needle knives, which can easily damage nerves. Additionally, these methods can lead to nerves growing close to the restraining structures after surgery, making nerve release difficult. Therefore, a new type of arthroscopic nerve release device is needed, which can conveniently release nerves without causing recurrence later. Utility Model Content

[0004] The purpose of this invention is to provide an arthroscopic nerve release device to solve the technical problem mentioned in the background art of making it convenient to perform release work on patients using an arthroscopic nerve release device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an arthroscopic nerve release device, comprising: a double blade, wherein the outer wall of the double blade is provided with a release mechanism, the release mechanism being used to facilitate nerve release in patients;

[0006] The facilitating release mechanism includes a bent handle, which is disposed on the outer wall of the double-blade head. A connecting rod is installed through the inner wall of the bent handle, and a circular handle is installed on the outer wall of the bent handle.

[0007] Preferably, the dual blades are biting tips.

[0008] Preferably, the connecting rod is used to connect the two sets of bent shanks and control the opening and closing of the double cutter heads.

[0009] Preferably, a nerve guide baffle is installed at the bottom of the dual blade head, and a plug plate is installed on the outer wall of the nerve baffle.

[0010] Preferably, the inner wall of the dual-blade head is provided with a groove.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. This utility model, by incorporating a mechanism to facilitate nerve release in patients, addresses the common practice of using plasma scalpels, blades, or small needle knives for arthroscopic procedures, which carries a risk of nerve injury. This poses a significant challenge for beginners. Furthermore, using ordinary blades to release the constraint structures on the nerve surface often leads to recurrence, as these structures readily re-adhere and grow back. Therefore, this new design facilitates nerve release by having the medical staff hold a circular handle and, under arthroscopic monitoring or direct visualization, open the double-blade head. The nerve baffle is inserted below the transverse ligament or constraint structure to be released, and the tissue is guided into the blade's incision. The blades are then closed to cut the tissue, and the fragmented tissue exits through the grooved structure. After cleaning, the release procedure can be performed safely under the protection of the nerve baffle, making the surgery safer. Furthermore, a gap is created in the middle of the constraint structure after release, preventing it from re-adheding and reducing the recurrence rate. Attached Figure Description

[0019] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "connected," etc. should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0020] Please see Figure 1 , Figure 2 and Figure 3 The arthroscopic nerve release device includes: a double-blade head 1, with a release mechanism on the outer wall of the double-blade head 1 to facilitate nerve release in the patient. The release mechanism includes a curved handle 2, which is located on the outer wall of the double-blade head 1. A connecting rod 3 is installed through the inner wall of the curved handle 2, and a circular handle 4 is installed on the outer wall of the curved handle 2. The double-blade head 1 has a pointed bite-shaped nozzle. The connecting rod 3 connects the two sets of curved handles 2 and controls the opening and closing of the double-blade head 1. A nerve guide plate 5 is installed at the bottom of the double-blade head 1, and a connector plate 6 is installed on the outer wall of the nerve guide plate 5. The inner wall of the double-blade head 1 has a groove 7. Because arthroscopic procedures currently often use plasma scalpels, blades, or small needle knives, which can easily injure nerves, this type of operation is more difficult for beginners. In addition, using ordinary blades to loosen the restraining structures on the surface of nerves is prone to recurrence later, which is related to the fact that the restraining structures can easily grow back together. Therefore, it is necessary to facilitate the loosening of the patient's nerves. The medical staff holds the round handle 4, and then, under arthroscopic monitoring or direct vision, opens the double blade 1. The nerve baffle 5 is inserted under the transverse ligament or restraining structure to be loosened. The tissue to be loosened is sent into the blade 1, and then the blades are closed to cut the tissue. The broken tissue can come out from the groove 7 structure. After the broken tissue is cleaned up, the loosening operation can be performed with confidence under the protection of the nerve baffle 5, making the surgery safer. After the loosening is completed, a gap will be formed in the middle of the restraining structure, making it difficult for the restraining structure to grow back together, thereby reducing the recurrence rate.

[0021] Working principle: Since arthroscopic procedures currently mostly use plasma scalpels, blades, or small needle knives, there is a risk of nerve injury. This makes the procedure even more difficult for beginners. Furthermore, using ordinary blades to loosen the constraint structures on the nerve surface often leads to recurrence, as these structures easily regrow and re-adhere. Therefore, a method is needed to facilitate nerve loosening. The medical staff holds the circular handle 4 and, under arthroscopic monitoring or direct vision, opens the double-blade head 1. The nerve baffle 5 is inserted below the transverse ligament or constraint structure to be loosened. The tissue to be loosened is then guided into the incision of the double-blade head 1. The blades are then closed to cut the tissue. The broken tissue can exit through the groove 7 structure. After cleaning the broken tissue, the loosening operation can be safely performed under the protection of the nerve baffle 5, making the surgery safer. After loosening, a gap is formed in the middle of the constraint structure, making it less likely for the constraint structure to regrow, thus reducing the recurrence rate.

[0022] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
