Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a fascia releaser. Background Art

[0002] Carpal tunnel syndrome and ankle tunnel syndrome are common neurological diseases. Due to ligament hyperplasia compressing nerves and blood vessels, they lead to related limb movement disorders and sensory disorders. Traditional treatments mainly include open surgery and acupuncture knife treatment.

[0003] Open surgery uses a scalpel to cut the skin and cut or snip the transverse carpal ligament to release pressure on nerves and blood vessels. However, open surgery has obvious disadvantages, such as large surgical wounds and long postoperative healing time, which affect the patient's normal life. At the same time, the common infection risks of open surgery bring great psychological pressure to patients. Although open surgery can achieve sufficient and thorough cutting, it is difficult to be widely used in clinical practice.

[0004] Acupuncture knife treatment opens a small wound on the wrist, and pushes or hooks the wound according to the doctor's hand feeling under non-direct vision.

[0088] or,

[0089] The upper part of the blade head 221 is a blunt stripping head that is slightly tilted upward and extends forward, and the lower part of the blade head 221 is a cutting blade.

[0090] In this embodiment, the shape of the cutter head 221 is limited to improve the safety of the surgical operation; there are two solutions:

[0091] In solution one, the blade head 221 is configured such that one side of the cutting edge is connected to the blade body 22 at an acute angle, and the side of the blade head 221 facing away from the cutting edge is connected to the blade body 22 in an arc shape; in this solution, the blade head 221 is more likely to slide in the tissue during surgery, reducing damage to surrounding tissues, and the cutting edge is sharper and more concentrated, which helps to cut tissue more accurately and effectively.

[0092] Solution 2: The upper part of the blade 221 is a blunt stripping head that is slightly tilted upward and extends forward, and the lower part of the blade 221 is a cutting blade. This solution combines the two functions of stripping and cutting. The blunt stripping head can be used to gently strip the tissue to reduce direct damage to the tissue, while the cutting blade below is used for precise cutting when necessary. This design increases the versatility of surgical tools, allowing doctors to choose the most suitable operation method according to surgical needs.

[0093] According to an embodiment of the present utility model, when facing the direction of the cutter head 221, the longitudinal cross-section of the main body of the loosening cutter body 22 is an inverted trapezoid.

[0094] In this embodiment, the longitudinal cross-section of the main body of the loosening knife body 22 is an inverted trapezoid. The size of the loosening knife body 22 matches the guide groove 12. The inverted trapezoidal design ensures that the loosening knife body 22 slides smoothly in the guide groove 12.

[0095] Working principle:

[0096] During specific use, a 2-3 mm incision is made with a dermatome at the surgical site after disinfection and anesthesia. The guide needle sheath 1 is first used to enter the incision, and blunt stripping is performed on the upper and lower parts of the target tissue to create a passage. Then, the main body 2 of the releaser is opened, and the blade head 221 lifts the incision skin and enters the subcutaneous tissue along the guide groove 12 of the guide needle sheath 1. The blunt stripping head on the head of the blade head 221 and the guide needle sheath 1 will directly form a C-shaped clamp. The blunt stripping head on the head of the blade head 221 will effectively press the target tissue (fascia) and promote cutting because it extends forward. At the same time, the blunt stripping head on the head of the blade head 221 can also effectively avoid damaging the subcutaneous nerves. After several pushes and cuts, the target tissue can be released.
